The modalities of communication are the sum of the expression dimension (linguistics) and the expressivity dimension (prosody), both being equally important in language communication. The expressivity dimension which comes first in the act of speech, is the basis on which phonemes, syllables, words, grammar, and morpho...syntax, i.e., the expression dimension of speech is superimposed. We will review evidence (1) revealing the importance of prosody in language acquisition and (2) showing that prosody triggers the involvement of specific brain areas dedicated to sentences and word-list processing. To support the first point, we will not only rely on experimental psychology studies conducted in newborns and young children but also on neuroimaging studies that have helped to validate these behavioral experiments. Then, neuroimaging data on adults will allow for the conclusion that the expressivity dimension of speech modulates both the right hemisphere prosodic areas and the left hemisphere network in charge of the expression dimension.Read more

We contrast three very distinct mathematical approaches to the hard problem of consciousness: quantum consciousness, integrated information theory, and the very large-scale dynamical systems simulation of a network of networks. We highlight their features and their associated hypotheses, and we discuss how they are ali...gned or in conflict. We suggest some challenges to these theories, in considering how they might apply to the human brain as it develops both cognitive and conscious sophistication, from infancy to adulthood. We indicate how an evolutionary perspective challenges the distinct approaches to aver performance advantages and physiological surrogates for consciousness.Read more

Many snakes live close to water, with several groups displaying morphological, physiological, or behavioral adaptions to aquatic environments. Although marine snakes have been found at depths beyond 200 m, freshwater snakes are rarely reported at depths larger than a few meters. Here we report freshwater depth records ...for the dice snake Natrix tessellata, an aquatic snake belonging to the family Natricidae. Dice snake was observed at depths down to 17 m, including in habitats below the thermocline, in Lake Orta (Northern Italy). These observations open new perspectives related to the biology and physiology of Palearctic freshwater snakes belonging to the family Natricidae.Read more

Six alkaloid compounds were isolated (the discovery of a natural drug, which is a combination of the six alkaloid compounds). Alkaloids viz., 1,3,5-Triazine-2-carboxylic acid, 4-amino-6-methyl; 1,2,4-Triazino[5,6-E][1,2,4]-triazine-3,6-dione, hexahydro; 2-(4,5-Dihydro-3-methyl-5-oxo-1-phenyl-4-pyrazole)-5-nitrobenzoic ...acid; 4-metyl-3,4-dihydro-[1,2,3] trizolo [4,5-d] pyrimidine-5,7-dione; Propanoic acid-3-(perhydro-2,5-dioxo-imidazol [4,5-d] imidazole-1-yl) and 1,2,3-Triazolo[4,5-f] benzotriazole- 4,8(4H,8H)-dione, were isolated from Cinnamomum verum cortexes by using ethanolic acetic acid, sulphuric acid, and ammonia solvents, and they were characterized by using preliminary qualitative tests, gas chromatography-mass spectrumGC-MASS.The medicinal efficacy was studied for these six alkaloidic compounds theoretically by using the Autodock program and the results showed the presence of high efficacy of the compounds. Then the medicinal efficacy was measured biologically for the six compounds mixture in vitro depending on the synergistic interaction principle by using various concentrations (5, 10, 15, 20, and 25 mg/ml) by using of agar diffusion technique. The results showed that the six alkaloidic compounds’ mixture is biologically active against Alternaria alternate fungus, where the inhibition zone diameters were recorded equal to 27, 33, 41, 45, and 49 mm respectively towards the pathogenic fungus. Also, cytotoxicity tests for the different concentrations of six active alkaloid compounds mixture proved there is no toxic effect belonging to them towards red blood cells, and no hemolysis effect appeared in blood cells. Therefore, six alkaloid compounds isolated from Cinnamomum verum cortexes can be used as active drugs for the treatment of various diseases especially those caused by pathogenic fungi represented by Alternaria alternate, without any side effects.Read more

Uremic toxins (UTs) are compounds derived from the metabolism of dietary molecules such as tryptophan (Indossyl Sulphate, IS) and phenil-alanine (P-Cresyl Sulphate, PCS), that are normally eliminated by the kidneys of healthy patients. The accumulation of such toxins is an indicator of kidney disease at different degre...es of severity, and the toxins can be found as free or protein bound in human biological samples. The toxicity of such compounds causes the loss of several biological functions, and the subjects suffering from such complications will need, more often than not, hemodialysis to properly excrete these toxins. Despite this not being a resolutive, but rather a symptom managing clinical approach, this is the most common course of treatment. Two analytical methods are proposed to quantify both the protein-bound and free forms of IS and PCS (HPLC-UV for the former; LC-MS/MS with ESI negative ionization for the latter), with lower variability and higher robustness than what is currently proposed, allowing for a precise simultaneous determination of the aforementioned UTs.Read more

This study presents a new assessment tool, FIKR (Facet, Insight, Knowledge, and Resilience) Personality Traits (PTs) for organisational talent development and leadership. The FIKR assessment tool offers a thorough framework for developing talent and leadership, covering facets, insights, knowledge, and resilience. By u...sing these elements, individuals can enhance their ability to successfully and strategically guide and influence others. Gaining self-awareness of one’s strengths and shortcomings, harmonising personal values with objectives for developing talents, obtaining the requisite information and abilities, and cultivating resilience not only promotes personal progress but also cultivates the potential of people within the organisation. By embracing the interaction of these FIKR characteristics, one may adopt a comprehensive and influential approach to talent development and leadership.Read more

There is constructed a qualitative model of the electrical conductivity of semiconductors irradiated with sufficiently high-energy particles. At certain conditions (irradiation temperature and dose, and subsequent thermal treatment), high-energy particles fluence, in addition to primary and secondary point radiation de...fects, forms a number of nano-sized disordered regions, highly conductive (“metallic”) compared to the semiconductor matrix. Their high total volume fraction can lead to the charge major carriers’ effective Hall mobility significantly exceeding that of the matrix. Due to elastic stresses created by these disordered inclusions, a high concentration of point radiation defects tends to form defective shells. In certain temperature ranges, such nanosized core-shell structures act as capacitors storing the electric charge sufficient for the Coulomb blockade of the major current carriers. Transformation of high-conductive inclusions into low-conductive (“dielectric”) ones manifests in a noticeable decrease in effective Hall mobility. The proposed model qualitatively explains all the experimental data available on single-crystalline n- and p-type silicon irradiated with high-energy electrons and protons and isochronously annealed.Read more

We present here the incompleteness of the Copenhagen interpretation regarding the impossibility of explaining the transition from the exact quantum mechanics to the Born-Oppenheimer approximation, where the inaccurate method captures phenomena like spontaneous symmetry breaking, but this is impossible to achieve with e...xact equations. The solution to this dilemma lies in the revision of quantum field theory which bounds together internal and external (vibrational, translational, and rotational) degrees of freedom in a similar way as the Lorentz transformation deals with space and time. This is the only way how to exactly mathematically justify the corrections beyond the Born-Oppenheimer approximation (Born-Huang ansatz). The consequences are overwhelming: It reveals the wrong BCS theory of superconductivity, derived on the basis of the incomplete quantum field, and all erroneous theories inspired by the BCS one (e.g. Higgs mechanism). Moreover, the second Bohr complementarity emerges from the mechanical wholeness and field fragmentation, opening the door for the megascopic mirror of the microscopic Copenhagen interpretation and for the explanation of megascopic quantum phenomena. Finally, we get an entirely new look at the meaning of physics and chemistry: The first one deals with microscopic and the second one with megascopic phenomena.Read more

This study explores the repercussions of excessive reliance on Artificial Intelligence (AI) on human cognitive processes, specifically targeting problem-solving, creativity, and decision-making. Employing qualitative semi-structured interviews and Interpretative Phenomenological Analysis (IPA), it delves into the nuanc...ed challenges and risks stemming from an overemphasis on AI.

Maize stem borer (Chilo Partellus), poses a substantial threat to maize crops all over the world, causing damage that ranges from 26.7% to 80.4%. Its destructive impact includes killing the shoot in young plants, leading to a “dead heart,” and damaging the upper stem in older plants through boring activity.... To combat this issue, a field experiment evaluated various insect growth regulators (IGRs) such as Lufenuron®, Pyriproxyfen®, Sitara®, Viper®, Track®, and Priority®. These IGRs, known as reduced-risk pesticides, target pest juveniles and are less harmful to beneficial insects. Conducted through a Randomized Complete Block Design (RCBD) with 24 treatments, excluding a control group, the study recorded maize stem borer populations at 3, 7, and 14 days post-IGR application. In conclusion, the study identifies pyriproxyfen® and Priority® at double the standard concentrations as highly effective insect growth regulators in mitigating maize stem borer infestations, offering promising avenues for enhanced pest control strategies in maize cultivation.Read more

The objective of this research paper is to examine and assess the correlation between the economic expansion of European Union member states and the escalating rate of motorization, which subsequently leads to road accidents resulting in significant loss of life and injury. A statistical analysis of economic growth, th...e rate of motorization, and road incidents in EU member states from 2010 to 2020 constitutes the research methodology. The research paper employs a quantitative approach to analysis and comparison. The research paper demonstrates how an increase in the number of motor vehicles in EU member states contributes to road accidents and human mortality. Varying degrees of economic development are associated with disparities between the rate of motorization expansion and the decline in fatalities. Because the rate of increase in motor vehicle usage surpasses the decline in fatalities per motor vehicle at low-income levels. At increased levels of income, the opposite occurs. Practical Implications: This research paper illustrates the importance for road traffic safety authorities to be aware of safety performance indicators and to incorporate them into legislative deliberations in order to bolster the European Union’s “zero victims” objective and provide enhanced protection for motor vehicle accident victims. Originality – This paper examines the correlation between motorization rates and fatalities in various EU member states with varying degrees of economic development over the past few decades.Read more

This study evaluates the impact of precipitation on water quality in Heidelberg, Germany’s recreational lakes during sporadic rainfall events from August to September 2023. Data were collected from five stations, monitoring physicochemical properties and nutrient levels before and after rainfall. Measurements of ...dissolved oxygen, pH, conductivity, and redox potential were conducted in situ, while turbidity, nitrates, phosphates, sulphates, zinc, and copper levels were analyzed in the SRH Heidelberg water laboratory. Findings indicate pH levels increased due to dilution effects, while conductivity rose due to runoff, enhancing ion concentration in the lakes. Dissolved oxygen levels also increased, attributed to aeration from rainfall-induced surface turbulence. Redox potential decreased, reflecting atmospheric oxygen dissolution. Nutrient concentrations, including nitrates and phosphates, along with sulphates, declined post-rainfall, suggesting a dilution effect without significant impact from surface runoff. This outcome implies the absence of major nutrient and sulphate sources upstream. Heavy metals like zinc and copper also decreased in concentration, indicating no introduction through runoff or sediment transport. The study underscores the variability of water quality parameters across different lakes, influenced by factors such as water sources, surrounding land use, geological conditions, and lake characteristics. Overall, water quality improved post-rainfall, making the lakes suitable for recreational activities, with the study establishing a non-linear correlation among the water quality parameters and deducing the P ratio for each parameter.Read more

The article provides information about modern problems of writing the Kazakh language, the importance of its role and development in the context of mass digitization using artificial intelligence technologies and computational linguistics methods. The incorrectness of the current alphabet of the Kazakh language based o...n the Cyrillic alphabet is proved in connection with the inclusion of Cyrillic letters in it, denoting phonemes that are not included in its sound structure. The necessity of reforming the Kazakh writing by replacing the incorrect alphabet is substantiated. Errors and contradictions are shown in the approved version of the Kazakh alphabet based on the Latin alphabet, as well as the alphabet proposed as a replacement for the approved one, in which some previous errors are repeated. In both cases, no analysis and clarification of the sound system of the Kazakh language, which is the basis of any alphabet, is carried out. In this study, to clarify the sound system of the Kazakh language, experiments were carried out to determine the articulation and acoustic features of Kazakh sounds with the help the computer programs used for many natural languages. In the articulation analysis, special attention was paid to vowels, which give rise to various contradictions in the Kazakh letter. It is proposed to use a new classification of vowels according to four binary features, rather than the traditional classification according to three binary features. Acoustic analysis uses the method of formant analysis, which is aimed at identifying certain formants in the spectrogram. The formant is obtained using a spectrograph. Quantitatively, the formants correspond to the maxima in the speech spectrum and usually appear on spectrograms as horizontal bands. After determining the composition and classification of the sound system of the Kazakh language, two variants of the alphabet based on the Latin alphabet are proposed: the first one is based on the Turkish alphabet using diacritical marks; the second is based on the English alphabet using digraphs. The second option offers ways to solve problems that arise when using digraphs. In conclusion, information is provided on the ongoing and ongoing work in Kazakhstan related to the creation of smart systems in the Kazakh language based on the methods and technologies of artificial intelligence and computational linguistics, the results of which are reflected in the list of sources.Read more

The aim of the study was to determine the incidence of laboratory aspirin resistance; and to study the associations of genetic markers and clinical and laboratory parameters (including parameters of the platelet hemostasis) in patients with non-cardioembolic ischemic stroke using machine learning methods to assess the ...prognosis of recurrent ischemic strokes. Clinical and laboratory data (including induced platelet aggregation) were analyzed from 296 patients with ischemic stroke who were treated in the stroke center of City Clinical Hospital No. 1 named after. N.I. Pirogov. The frequencies of polymorphic variants of the ITGB3, GPIba, TBXA2R, ITGA2, PLA2G7, HMOX1, PTGS1, PTGS2, ADRA2A, ABCB1, PEAR1 genes and intergenic region 9p21.3) in patients with non-cardioembolic ischemic stroke, which were identified using hydrogel biochip technology, were determined. Using the developed machine learning model, additional clinical and genetic factors influencing the development of laboratory aspirin resistance and recurrent ischemic stroke were studied. In the future, the identified factors can be used for differentiated prevention of recurrent ischemic strokes.Read more

Upon dysfunction of the Endoplasmic Reticulum (ER), eukaryotic cells provoke a gene expression program, namely, the Unfolded Protein Response (UPR), leading to an increase in the size and function of the ER. In the yeast Saccharomyces cerevisiae, the UPR is modulated by the Hac1i protein, which is a transcription facto...r produced by ER stress. When the UPR is artificially triggered under non-stress conditions by artificial expression of the Hac1i protein, S. cerevisiae cells carry an enforced and enlarged ER, which allows us to obtain commercially valuable materials such as secretory proteins and functional lipids abundantly.Read more

The finite Markov chain to which there correspond the qualities of the conformational dynamics of the K-Ras4B proteins in the catalytic reaction is written. The corresponding Markov-Sates models are studied. The properties of the K-Ras4B processes Markov chain allow one to define a new two-state MSM for the analytical... description of the final-state transition. The time evolution of the eigenvalue corresponding to the final-state transition in the Galerkin description is written. The tools for the analytical calculations of the relative error are therefore prepared. New analytical formulations of the time evolution of the eigenvalue corresponding to the final-state transition are newly written from the experimental data and form the properties of the lag time in shaping the discretization error. The features of the discretization error are newly studied. A comparison with the experimental data is proposed.Read more

Since time immemorial, Indigenous communities have always perceived the landscape as a complex web of living, physical, and spiritual things. These communities have always relied on their Indigenous knowledge systems (IKS), emphasizing ancestral burial grounds, mountains, caves, rivers, pools, forests, monuments, and o...ther cultural diacritics as symbols of place identity. In addition, myriad metaphors like taboos, legends, tales, folklore, myths, proverbs, stories, and practices, also constituted an integral part of Indigenous cultural and nature connections. This heritage was constantly imagined and configured to cement human-nature relations. However, the advent of colonialism severely violated this status quo, thereby causing deep environmental, political, and social crises. Through imposing a hegemonic scientific paradigm, knowledge compartmentalization, and capitalist aggrandizing practices, the original harmonious human-nature praxis premised on IKS was disrupted. To this day, the exclusionary colonial legacy and poisoned ‘sense of place’ remains our greatest threat to climate and environmental stability. Thus, this paper advocates for the recentralization of IKS as a valid way of knowing with already inbuilt human and natural disaster management solutions. By pivoting Rozvi narratives premised on five mountains, namely; Manyanga in Bubi district, Mavangwe, MunwewaMwari and Bepe in Buhera district, and Mutikwiri in Maungwe near Rusape town, all situated in former Butua/Guruuswa regions of Zimbabwe as case studies, the power of ancient wisdom as a holistic epistemic approach towards sustainable human-nature relations is explicated.Read more

The paper reports on the life and works of Fred Vlès (1885-1944) and Paul Reiss (1901-1944), and Charles Laville (1877-1959) who worked in a similar field. Vlès was the founder of the first institute of biophysics in France at the University of Strasbourg, and Reiss was his pupil and associate. They worke...d in the time of 1910 to 1944 on the acid-alkaline balance and the reduction-oxidation (redox) potentials of the body fluids and tissues and their influence on the proteins and colloids of the “terrain”, along the lines given by the “milieu interne” (internal environment) or homeostasis concept by Claude Bernard. Vlès and Reiss were also electrobiologists and were some of the first scientists to investigate the physiological effects of electrical grounding where also the work of Charles Laville is relevant. In the conclusion we link this historical narrative to contemporary research.Read more

The use of polycarboxylate ether superplasticizer PCE in the preparation of mortars and concretes influences the hydration kinetics and the amount of total heat released. This leads to a modification of certain properties of the mortar, namely workability, calorimetry and mechanical resistance. In this study two ether ...polycarboxylate superplasticizers with different chemical structures were used; they were incorporated at different dosages into a standardized cement-based mortar. The objective of this work is to study the effectiveness of these superplasticizers and to select the most compatible product with cement and the most suitable for use according to the climates of the country. The impact of superplasticizers on fresh cement was studied by measuring the Marsh cone flow time and calorimetric measurement. In the hardened state, the mechanical properties were provided by measuring the compressive strength. The results show that low dosages of ether polycarboxylate superplasticizer promote grain hydration and produce more heat. On the other hand, high dosages delay the contact of the cement grains with the mixing water and cause a reduction in the final heat released and a delay in setting. The ether polycarboxylate superplasticizer with high carboxylic density gives the best mechanical resistance compressive at 7 and 28 days.Read more

For the first time, a method for calculating formulas of homologous series of chemical compounds of the systems (Aa+ – Bb+ – Cc–) and {Zn2+ – Ge4+ – P3–} in a generalized form is presented. The calculation is confirmed by the literature experimentally obtained compounds: thirteen com...pounds of the system (Na+ – Ti4+ – O2–), seven – systems (Li+ – Ti4+ – O2–), five – systems (K+ – V5a+ –  – O2–), eight – systems (Ba2+ – Cu2+ – O2*). Homological series in (Aa+ – Bb+ – Cc–) have the following generalized form: A{t – k·r + nr – r)bcBracC{t – k·r + nr)ab and AtbcB{r – k·t + nt – t}acC (r – k·t + nt)ab.In (Zn2+ – Ge4+ – P3–) systems for the m-group the formulas of homologous series, that develops towards Ge3P4, have the following generalized form: Zn6tGe(6r – 6kt + 6n – 6t)P(8r – 8kt + 8n)  and for αm-homologous series – Zn6Ge3nP4(n + 1). A method for calculating formulas of homologous series of chemical compounds in a generalized form can be used for any system of chemical elements.Read more

The mango, known as the {king of fruits}, is commercially significant in many parts of the world. In addition to offering a delicious tropical flavor, mangoes are a great source of nourishment and can make eating a satisfying and healthy sensory experience. Even though mango farming is known to exist in more than 120 n...ations, just 15 of them are responsible for more than 1% of the world’s supply. More than 60% of the mangoes produced worldwide are grown in India, China, Thailand, Indonesia and Mexico. The effects of climate change on agriculture must take into account the increasing CO2 concentration, a significant contributor to climate change, as CO2 is essential to critical plant functions, including photosynthesis. The fluctuation of temperature represents another climatic factor that affects mango productivity. The primary challenge facing the mango industry is irregular cultivation. The mango flowering was negatively impacted by the erratic distribution of cold nights and relatively warm winters. Mango output is already being impacted by rising average maximum temperatures. Therefore, regardless of mango growers, geniuses, or consumers, rapid climate change should be a top priority. A benefit of selection and breeding operations to adapt to climatic change is the high genetic variety of mangoes.Read more

This research reveals the previously unexplored pharmacognostic potential of antidepressants found in nutrients derived from both legume and animal sources. Through preclinical investigations involving mouse models, the study focused into antidepressant and antioxidant activities of non-denatured and denatured protein ...extracts from beans and eggs. Non-denatured protein extracts from beans and eggs, at saturation levels of 40% and 80%, were examined as macronutrients, while denatured protein extracts at equivalent saturation levels were considered micronutrients. The study employed the DPPH and hydrogen peroxide tests to assess antioxidant activity, and the forced swimming test and sucrose preference test to evaluate acute and chronic mild antidepressant effects, respectively. The acute toxicity study revealed that macronutrients from eggs at 40% and 80% saturation displayed non-toxic effects (LD50 >5 g/kg), while those from beans, specifically at saturation of 80%, exhibited a relatively low level of toxicity (LD50 = 2.5 g/kg). Evaluation of antioxidant activity using the DPPH test yielded inconclusive results due to the influence of ethanol precipitation. In contrast, the H2O2 test demonstrated significant antioxidant potential in both macronutrients and micronutrients extracted from beans and eggs at all saturation levels. In investigating antidepressant properties, both macronutrients and micronutrients of bean and egg protein extracts at 40% and 80% saturation exhibited notable antidepressant effects, particularly the micronutrients at saturation of 80%. This antidepressant effect was characterized by a reduction in immobility time and an increase in sucrose preference.In conclusion, this study uncovers the multifaceted potential of protein extracts sourced from natural products, plant and animal origins, as agents for treating depression. It opens up new avenues for research, with implications ranging from neuroprotection to the management of depression, inspiring optimism for innovative approaches to mental health treatment.Read more

Synthetic approaches to the construction of the heterocyclic benzo[4’,5’]imidazo[2’,1’:6,1]pyrido[2,3-d]pyrimidine system based on heterocyclizations of substituted benzimidazoles and a new alternative strategy based on 2,4,6-trisubstituted pyrimidinyl-5-propanoic acids are considered. The latte...r method has been shown to be a successful addition to previously described methods, since it allows one to bypass the significant limitations associated with the use of substituted benzimidazoles and allows the introduction of functional substituents at different positions of the heterocycle that are inaccessible by other methods. The available information on derivatives of this heterocyclic system and their biological properties is summarized.Read more

This work is carried out to fill the epistemic and hermeneutical gap within Igbo socio-metaphysical space. Notable works have been done in Igbo studies, however, the place of the Dibia in Igbo ontology has been neglected, hence the current work. The researchers combined library and fieldwork approaches in executing thi...s work. In the end, the research notes that modern Igbo people have neglected the place and activities of the Dibia. Noting that the Dibia being the active presence of the God[s] among the people is an indispensable persona in the Igbo existence. Therefore, the current crisis of relevance the people are experiencing is a result of this neglect. The works, therefore, conclude that if the Dibia and her activities are brought back to the centre stage of Igbo existence, the socio-political and economic crises of the moment would have been a history.Read more

Energy Valley Optimizer (EVO) is one of the recent metaheuristic algorithms. It draws inspiration from advanced principles in physics related to particle stability and decay modes.

Levy flight is one of the most important randomization techniques. Fifteen mathematical test functions (five unimodal functions, four multimodal functions, and six composite functions) are solved with the proposed algorithm. We also compare our results with previous results of metaheuristic algorithms. The statistical results show that the results of the Levy Energy Valley Optimizer (LEVO) outperform other algorithms in almost all mathematical test functions.Read more

Cyber Threat Analysis (CTA) in current conflicts focuses on identifying, monitoring, and assessing potential cyber threats. The main objective is to understand how the parties to the conflict use information and network technologies to conduct warfare, espionage, disinformation, or attacks on digital infrastructure. Th...is analysis includes the identification of actors involved in conflicts and their targets in cyberspace, as well as the analysis of techniques and tools used in cyber activities. The aim of the article is to identify the role of cyber threat analysis in the context of two current conflicts - the war in Ukraine and the Hamas attack on Israel. The article describes the essence of cyber threat analysis. The research problem focuses on identifying and understanding the role of cyber threat analysis in these conflicts and their potential consequences for international security and regional stability. Through the analysis of reports, online sources, and scientific literature, the article aims to familiarize readers with the role of cyber threat analysis in the context of these conflicts and to propose possible strategies for cyber risk management in the face of contemporary armed conflicts. The results of the analysis of cyber threats (CTA) in current conflicts include the identification of specific actors operating in cyberspace, their modus operandi, their objectives, and the techniques and tools used. In addition, the analysis can reveal existing vulnerabilities in digital security and areas that are particularly vulnerable to attacks. To sum up, it is necessary to create recommendations and directions for changes regarding the strengthening of digital security measures, such as software updates, implementation of network security, and increasing staff awareness of cyber threats. In addition, the CTA may suggest the need for better international cooperation to combat cyber threats and the need to develop strategies to prevent and respond to cyber-attacks.Read more

This case study investigates the implementation of Virtual Reality (VR) technology in facilities management Competency-Based Training (CBT) within one of Singapore’s leading facilities and township management companies. Traditionally, workplace training in facility management has relied heavily on lecture-based m...ethods, often resulting in insufficient preparation and a high turnover rate among newly onboarded staff. To address this challenge, this study explores the conversion of training materials into VR-based courseware, enabling immersive and interactive learning experiences.Two groups of newly onboarded staff underwent either traditional lecture-based or VR training sessions. Results indicate that those trained using VR exhibited a better comprehension of the material and higher levels of motivation compared to their counterparts in the traditional lecture-based group. However, it was noted that VR training carries the risk of cybersickness, with some participants reporting symptoms such as dizziness.

Many UK inhabitants now adopt careers working in both university and manufacturing sectors. In a typical engineering career, a young student may now start at university, spend time in factories, often in research and development, and then return to university in later life to teach evolving innovation principles of ind...ustry. It is clear to such people that universities are expanding rapidly whereas manufacturing has declined and reached an equilibrium of output but with lower job numbers due to robotics. Manufacturing in 2022 was approximately 8% of British GDP whereas the university sector was only about 2%. This paper analyses the growing connections and co-locations with numerous universities/manufacturing companies, predicting that convergence in both jobs and GDP contribution will occur around 2050.Read more

Today’s cadet leader is tomorrow’s officer, a professional capable of integrating knowledge and solving complex problems in a full-scale war with incomplete information, being a leader and authority for the personnel. Most of the time, cadets study in study groups using traditional technology, which is not ...enough to form a professional cadet leader. With the advent of computer technology, students’ and cadets’ motivation to learn using traditional teaching methods has paradoxically begun to decline rapidly. The problem of the quality of training of military specialists for the needs of communication and cybersecurity units is not reflected in the publications reviewed. However, significant progress has been made in the use of computer technology as the basis of training tools for ground forces units. Similar training complexes are actively used in NATO member states in the military education system in the training of air force pilots (navigators). Therefore, the author chose the improvement of the educational process at the Department of Combat Use of Communication Units in combination with the methodology of professional-business game for the development of a cadet leader in professional training courses (L-1B) of the tactical level of military education as the direction of research. The purpose of the study and the article is to substantiate the conceptual view of the department in the need to build a computerized training complex for training officers of leaders in professional training courses (L-1B) of the tactical level of military education, capable of using communication units based on computer games. Fragments of the game mechanics of stimulating the interest and motivation of cadets to study, for example, electronic shooting range, and learning Morse code, are considered.

Fractals are complex structures that repeat themselves at several scales. Nature exhibits these in many forms like snowflakes, mountains, coastlines, the human brain/lungs/ nervous system, and many more. It appears that these are nature’s organic way of growth. Thus, there is an underlying science that works to g...row or create these self-similar patterns. In this work, tin oxide-based fractals have been grown under laboratory conditions and applied to a gas-sensing field. The facile growth methodology successfully grows fractals on a large scale. The tin oxide fractals have unique basic building units that connect and grow in different directions. These tin oxide fractals have successfully sensed ethanol vapors in the range of 20 ppm to 100 ppm. The best sensing response has also detected ethanol vapors as low as 10 ppm at room temperature with response and recovery times of 18 ± 3 s and 22 ± 5 s, respectively. The best sensing response recorded for such sensors was under 12 s. The characteristic fractal growth is attributed as the defining factor that enhances ethanol sensing at room temperature.Read more

The pervasive Internet of Things (IoT) integration has revolutionized industries such as medicine, environmental care, and urban development. The synergy between IoT devices and 5G cellular networks has further accelerated this transformation, providing ultra-high data rates and ultra-low latency. This connectivity ena...bles various applications, including remote surgery, autonomous driving, virtual reality gaming, and AI-driven smart manufacturing. However, IoT devices’ real-time and high-volume messaging nature exposes them to potential malicious attacks. The implementation of encryption in such networks is challenging due to the constraints of IoT devices, including limited memory, storage, and processing bandwidth. In a previous work [1], we proposed an ongoing key construction process, introducing a pivotal pool to enhance network security. The protocol is designed with a probability analysis to ensure the existence of a shared key between any pair of IoT devices, with the predefined probability set by the system designer. However, our earlier model faced vulnerabilities such as the “parking lot attack” and physical attacks on devices, as highlighted in the conclusion section. We present a complementary solution to address these issues, fortifying our previous protocol against cyber threats. Our approach involves the implementation of an internal Certification Authority (CA) that issues certificates for each IoT device before joining the network.Furthermore, all encryption keys are distributed by the primary IoT device using the Unix OS ‘passwd’ mechanism. If a device “disappears,” all encryption keys are promptly replaced, ensuring continuous resilience against potential security breaches. This enhanced protocol establishes a robust security framework for IoT networks, safeguarding against internal and external threats.Read more

The currently existing Russian and other legislation, as well as special literature, do not contain a methodology for the formation of the business reputation of the organization’s personnel and as a result, there is no unambiguous perception of the business, professional qualities of personnel as an object of ev...aluation of the organization in the market system. Therefore, it is impossible to single out the share of the results of intellectual advantage in the goods and services produced. This confirms the requirements formulated in paragraph 4 of Accounting Regulation 14/2007 «Accounting for intangible assets», which states that the intellectual and business qualities of the organization’s personnel, their qualifications, and their ability to work are not included in the intangible assets (since they are inseparable from their carriers and cannot be used without them). Meanwhile, the interests of the leading economically developed countries of the world lie in the field of accelerated growth of knowledge acquisition and application of professional skills. This trend of development of economically developed countries forms the basis of competitiveness and efficiency of their work. It should be noted that in the world economy, there is insufficient theoretical elaboration and a special practical significance and relevance of the issue of assessing the business reputation of the personnel of an economic entity. The article presents a comprehensive methodology for evaluating the performance of industrial and production personnel (the standard-production methodology), which contributes to the formation of accounting and information support for the analysis of the activities of both structural divisions, responsibility centers, business segments and commercial organizations as a whole. The author’s standard-production methodology makes it possible to determine the business reputation of industrial and production personnel, which contradicts the official economic paradigm.Read more

People are suffering from” data obesity” as a result of the expansion and quick development of various Artificial Intelligence (AI) technologies and machine learning fields. The management of the current techniques is becoming more challenging due to the data created in the Smart-Health and Fintech service ...sectors. To provide stable and reliable methods for processing the data, several Machine Learning (ML) techniques were applied. Due to privacy-related issues with the aforementioned two providers, ML cannot fully use the data, which becomes difficult since it might not give the results that were expected. When the misuse and exploitation of personal data were gaining attention on a global scale and traditional machine learning (CML) was facing difficulties, Google introduced the concept of Federated Learning (FL). In order to enable the cooperative training of machine learning models among several organizations under privacy requirements, federated learning has been a popular research area. The expectation and potential of federated learning in terms of smart-health and fintech services are the main topics of this research.Read more

The result of this research will illustrate the importance of geothermal energy as an alternative renewable energy in Indonesia to replace crude oil resources as the main natural resource in Indonesia. This research recommends the mapping of resources, requiring technology as a breakthrough in processing geothermal energy to take it directly from the reservoir because of its unorthodox classification based on its source as well the cost and benefit impact on the economy related to consumer mapping to detect early the market changes of energy to geothermal.Read more

The article presents a case study on the Investigation of lateral vibrations in the turbine-generator unit 5 of the Inga 2 hydroelectric power plant in the Democratic Republic of the Congo. Lateral vibrations were experimentally determined using twelve proximity and eddy-current probes, positioned on each measurement p...lane. The results were analyzed using the Dasylab and R software. Hence, it was observed that the vibration amplitudes of the upper guide bearing, lower guide bearing, and pivot/rotor exceeded acceptable or critical limit values of the international vibration standard for a rotating speed between 100-250 rpm. These excesses can lead to rotor mass imbalances, the eccentricity of the rotor axis relative to the rotation axis of the shaft, and the deformation of the coupling shaft between the upper rotor shaft and the turbine rotor shaft. Subsequently, the means and the variances of the vibration amplitudes were evaluated and compared to the reference values of the international standard. The results of the compliance analysis revealed statistically significant differences between the measured amplitudes and the reference values. Thus, it indicates deviations from international specifications.Read more

The operating experience of mechanical seals shows that as a result of angular deformations of the rings, the wear of the contact surfaces along the radius is uneven. When designing mechanical seals, it is necessary to calculate the amount of expected leakage through the seal, friction power consumption, as well as the... possible durability of the unit. These calculated dependencies and estimates are obtained based on the constructed mechanical seal model. In the area of hydrodynamic load support in the case of a confusor joint or a converging film, the slope of the pressure diagram is such that a decrease in the film thickness increases the hydrodynamic support. This is referred to as enabling stable non-contact sealing operation. The execution of the rubbing surfaces of the interface of the end pair should ensure the formation of the calculated confusor shape of the sealing gap in all modes of operation and axisymmetric pressure fields during the rotation of the rotor.Read more

This paper tackles the vital issue of missing value imputation in data preprocessing, where traditional techniques like zero, mean, and KNN imputation fall short in capturing intricate data relationships. This often results in suboptimal outcomes, and discarding records with missing values leads to significant informat...ion loss. Our innovative approach leverages advanced transformer models renowned for handling sequential data. The proposed predictive framework trains a transformer model to predict missing values, yielding a marked improvement in imputation accuracy. Comparative analysis against traditional methods—zero, mean, and KNN imputation—consistently favors our transformer model. Importantly, LSTM validation further underscores the superior performance of our approach. In hourly data, our model achieves a remarkable R2 score of 0.96, surpassing KNN imputation by 0.195. For daily data, the R2 score of 0.806 outperforms KNN imputation by 0.015 and exhibits a notable superiority of 0.25 over mean imputation. Additionally, in monthly data, the proposed model’s R2 score of 0.796 excels, showcasing a significant improvement of 0.1 over mean imputation. These compelling results highlight the proposed model’s ability to capture underlying patterns, offering valuable insights for enhancing missing values imputation in data analyses.Read more

The textile sector has great relevance in the Brazilian socioeconomic context, generating large volumes of effluents of varied composition, with dyes being one of the most worrying contaminants due to their characteristics of high solubility, harmfulness and low degradability. Among them the Reafix Yellow B8G (ARB8G) d...ye has an azo nature, harmful to organisms in the aquatic environment. According to Brazilian laws, it is recommended to dispose of waste through incineration or landfill, due to its resistance to biodegradation. One of the methods for treating effluents is the adsorption of contaminants using materials with adsorption capacity, such as residue from the burning of biomass in boilers (ash). The general objective of this work was to evaluate the adsorption kinetics by contact time of the ARB8G dye by boiler ash. The test was based on mixing the adsorbent material with a dye solution at 75 mg.L-1, at constant temperature and stirring at different time intervals. To quantify the amount of adsorbed dye, the UV-Vis spectrometry method was used. The kinetic test indicated an equilibrium time of 30 minutes, with 100% removal under the tested conditions. From this result and considering that boiler residue is an underutilized and low-cost material, it is concluded that this substance has significant potential to be applied as an alternative material for the treatment of effluents containing dyes.Read more

The article obtained systematized, scientifically substantiated gross, technical, economic, and environmental energy resource potentials from the introduction and use of solar energy technologies. The technical, economic, and environmental priorities of power plants were assessed in terms of energy efficiency, fuel eco...nomy, and the environmental impact per square meter from conversion to thermal and electrical energy in the city of Arkadag.The calculated results are, kWh/m2 per year: gross resource potential of solar energy - 1844.6; the technical potential for conversion into thermal and electrical energy is equal to - 1256.44 and 242.44; economic - 502.6 and 96.98 kg fuel equivalent/m2 per year; environmental reduction in emissions of various harmful substances into the environment when using solar photovoltaic modules in the city of Arkadag will be: with annual electricity generation per m2 - 242.44 kW⋅h, annual fuel consumption savings - 96.96 kg. e., the reduction in emissions will be, kg per year: SO2 – 2.0; NOx – 1.1; CO – 0.14; CH4 – 0.29; CO2 – 155.0; solids – 0.21; when converted into thermal energy per m2 and annual production of 1256.4 kW⋅h, annual fuel savings are 502.6 kg of fuel equivalent; emission reduction will be, kg per year: SO2 – 10.4; NOx – 5.6; CO – 0.73; CH4 – 1.53; CO2 – 803.5; solids – 1.1.Empirical equations (1-5) have been obtained taking into account the gross, technical, economic, and environmental resource potentials of solar energy in the city of Arkadag, it is possible to carry out energy and environmental forecasting when drawing up a feasibility study.Read more

A new design of a fine positioner or high precision driven unit with a large positioning range is proposed for a custom-made in-situ indenter device equipped inside an SEM chamber. The design configuration of the proposed system is size-effective for the confined working area of the SEM chamber. The indentation depths ...can be precisely varied by controlling the fine positioner driven by a piezoelectric actuator. The main goal is to achieve very deep penetrations toward the bottom layers of tall or large-size scale specimens by single indentation, without the need for sequential indentations. Thus, the proposed design can eliminate the need for sequential adjustments of the specimen position with respect to the indenter tip as currently being practiced by the researchers. The specimen position adjustment after each indentation heavily depends on the coarse positioner and its accuracy level in a sub-millimeter regime which could result in position errors and unwanted lateral forces in the nanoindentation process. Therefore, the sequential indentations technique could lead to considerable variations in the outcomes of nanoindentation tests done on similar specimens. The proposed design will be realized to deploy in the Continuous Stiffness Measurement (CSM) techniques generally used to evaluate elastic properties as a function of continuous penetration depth with high-frequency loading and unloading cycles.Read more

All professional technical assessment processes are fraught with uncertainty. If a decision is premised upon the result, the decision maker must understand the reliability of the performed assessment. A causal theory application is developed utilizing distinct (linguistic, ordered) terms and continuous (numerical) vari...ables. It uncouples the methods from the result of the assessment obtained and focuses on those aspects that are important to the reliability assessment of the conclusion, not the answer itself. Matrices provide a means of characterizing the uncertainty of the methods and information available for each principal issue impacting the reliability. These matrices are determined as paired qualitative assessments of the Quality of the Measures Used and the Quality of Implementation of component description measures. Each is qualified by two to five grades, allowing three, five, seven, or nine quality distinctions for the assessed element. Uncertainty β values are determined for each component of the assessment combined by either an RMS procedure or a weighted average and converting a numerical value back to a consistent linguistic term. This procedure yields a basis for using good judgment while being sensible and reasonably cautious by independently determining the reliability using a carefully considered approach. California State University has assessed seismic retrofit priorities for 56 buildings using this method and has committed to its continuing use as its retrofit priority evaluation tool.Read more

Epithelial ovarian cancer is one of the most common causes of cancer-related death in women. More than half of patients are diagnosed at an advanced stage, usually due to the locoregional spread of peritoneal carcinomatosis. We present the case of a 49-year-old woman who suffered from constitutional syndrome and abdomi...nal distention. The imaging tests revealed two large, vascularized, and heterogeneous masses that depended on both ovaries. Bilateral adnexectomy was performed and the result of the anatomopathological study was endometrioid carcinoma moderately differentiated. The patient was treated according to the latest recommendations of the NCCN guidelines. A combination of systemic chemotherapy and cytoreductive surgery has been the standard treatment since the mid-1990s. However, a combination of hyperthermic intravenous and intraperitoneal chemotherapy may reduce plasma toxicity and increase therapeutic effectiveness.Read more

Fungi, and especially mold fungi, play a very important role in natural environments, as well as in the food industry for the production of many specialized products. However, many of them, under favorable conditions, are capable of producing toxic compounds called mycotoxins. Many of them have an adverse effect on the... growth and development of all groups of organisms, including humans. Mycotoxins can appear in all food products and animal feed. Mycotoxins accumulated in food of plant and animal origin and consumed by humans can accumulate in various tissues and organs, which results in disorders in their functioning and may cause cancer. Plants have the ability to defend themselves against mycotoxins by neutralizing them as a result of the glycosidation process. Mycotoxins neutralized in this way are called “masked mycotoxins”, which are not toxic to plants, but after entering the body of animals or humans in the digestive tract, they return back to their original toxic form. Let’s appeal and spread knowledge about mycotoxins because they pose a constant threat to the health of people and farm animals.Read more

Background: Rectal toxicity is an important side effect of prostate cancer irradiation affecting 25% of patients. The role of dosimetric variables has a set of dose-volume constraints and curves to estimate the risk of rectal damage. The rectum position at the time of CT planning is different from the position during r...adiotherapy. Three methods are available to achieve optimal rectum position: enema; prostate cancer spacer; fiber-/fat-free diet. Methods: A 70.2 Gray radiation divided into 26 hypo-fractions was administered to 115 patients with prostate cancer by VMAT referred to a single center in Italy. To empty the rectum, all patients were administered a fiber-/fat-free diet and those with Eating Disorders (ED) were also added with activated charcoal (2 tablets/day) and a macrogol-based medical device (2 sachets/day). During treatment, the volumetric amount of rectum in the target was measured by comparing control-CT with simulation-CT, and acute toxicity was also checked. Results: The rectum position during control-CT in diet-only patients (29) predicted toxicity recorded during treatment, while in the ED group rectum position was adherent to position during simulations. Rectal volume target > 0.25 cc receiving a dose > V70 caused acute G3 toxicity that attenuated or worsened with rectal displacement. Acute rectal toxicity occurred in 6/29 (20.68%) patients (1 G3, 5 G1) in the diet-only group, while only in 1/86 (1.16%) patients (G1) in the ED group. No chronic toxicity was recorded in either group. Conclusion: Prostate cancer patients treated with VMAT, diet, charcoal, and macrogol emptied the rectum optimally and reduced incidence and severity of acute rectal toxicity, also with benefit on late toxicity.Read more

Breast cancer is the most common type of cancer in women worldwide. It can be spread when cancer cells get into the blood or lymph system and then are carried to other parts of the body. As it is one of the leading causes of death among women, this study aims to identify the most relevant risk factors for breast cancer... through several prevention methods for early detection. The social impact of breast cancer is so strong that the World Health Organization (WHO) has established 19 October as International Breast Cancer Day. The pink ribbon is the symbol of this important day worldwide. The objective is precisely to raise awareness among the population about the disease and promote access to timely and effective diagnoses, checks, and treatments.Good prevention should be carried out through behavior or lifestyle modifications (e.g., diet, physical activity, alcohol limitation, etc.). Although, certain risk factors cannot be modified (e.g., aging, family history). Screenings are a fundamental tool to deal with breast cancer, even if sometimes they are not enough as in the case of interval cancers or in cases of particularly ambiguous presentation. Worldwide organizations recommend screening by means of ultrasound, mammography, and magnetic resonance, with appropriate follow-up for an abnormal screening test. To avoid overdiagnosis and overtreatment that can lead to long-term complications and false negatives, these screening differs by recommended ages and frequency. Identification of women at risk for BRCA1 and BRCA2 mutations is also recommended with a referral for genetic testing and, in the presence of dubious lesions, a biopsy is needed. In order to fight this disease, is important to act on time, so, information is fundamental. First of all, the female population should be conscious of risk factors and of the importance of breast examinations from a young age, lastly, they should be aware of the possibility of joining programs of free screening.Read more

Incisional acute wounds of the skin are characterized by a rapid biomechanical response by stromal cell contraction that joins the wound lips through the fibrin cloth. In this work, we have performed an in vitro model using Fibroblast-Populated Collagen Lattices (FPCLs) that partially mimic that physiological process. ...Injured FPCLs under relaxed or stressed conditions were evaluated over time, and cross-sections of the lattices were stained with picrosirius red. Wounds filled with fibrin in relaxed FPCLs were closed earlier than controls, the fibrillar pattern of the collagen lattice was different between the wound and the edges of the lattice. On the other hand, stressed FPCLs did not close wounds, even those filled with fibrin, because the tension generated from the lattice borders maintained high tension towards the wound. Controls or fibrin-treated stressed FPCLs, showed high tension in the wound matrix, characterized by the high packing of collagen observed like yellow-red birefringent fibers when stained by picrosirius red. Despite wounds that remain open, fibrin-treated FPCLs exhibited less wound area than controls. With this work, we have demonstrated that FPCL models can be used to study wound closure, mainly when they are improved with other elements of the wound environment that allow us to analyze the biological process.Read more

Smooth muscle tumours are the most common mesenchymal tumors of the vulva and vagina, yet their infrequency is demonstrated by the prevalence of published reports as individual cases or small case series.This article reports a case of a 42-year-old woman who presented with apparently recurrent vulvovaginal leiomyoma an...d a past history of surgical excisions. Histopathology revealed Smooth Muscle Tumor of Uncertain Malignant Potential (STUMP).Read more

Background: Firefighters are subject to a variety of stressors, hence the importance of equipping them with resources that contribute to the management of these stressors. Aims: Considering that a healthy lifestyle is one of these resources, this study aimed to characterize the lifestyle of a Portuguese firefighte...rs sample, rate their general lifestyle level, and analyze its association with their subjective well-being (i.e., flourishing). Methods: A sample of 860 firefighters responded to an adapted version of the FANTASTIC. Results: The results showed that most (72.8%) had a good lifestyle. However, regarding each habit, a significant percentage had bad habits: sometimes consuming high-calorie foods (81.2%); sometimes having difficulties sleeping (50.9%); drinking more than 4 - 5 alcoholic drinks on the same occasion (43.9%); and exceeding their ideal weight by more than 8 kg (29.7%). However, a marked percentage also had healthy habits: having people to talk to (71%) and giving and receiving affection (63.5%); exercising at least once a week (81.5%); not smoking (63.9%); almost always eating healthily (26.7%); sometimes sleeping well (50.2%); and managing stress (56.7%). As expected, the assumption that firefighters’ lifestyle is related to their flourishing was supported. Conclusion: A healthy lifestyle is an important resource to ensure the firefighters’ flourishing and should be a part of the day-to-day life of these professionals.Read more

Post-stroke aphasia and hand movement dysfunction are common and disabling conditions. Observations indicate that most patients with post-stroke aphasia also suffer from hand movement dysfunction. Research in human evolution, behavior, and neuroscience has revealed a strong connection between language function and hand...-motor function, with the latter playing a critical role in language use. Consequently, there is an urgent need for the development of new, comprehensive, and efficient rehabilitation methods for post-stroke aphasia that is accompanied by hand dysfunction. One promising approach involves investigating the shared neural networks between language and hand function as a foundation for novel treatment methods. This article aims to review the current state of clinical research on comprehensive treatments for stroke-induced aphasia and hand dysfunction, as well as to explore their underlying neural mechanisms. The results of this study may provide a valuable reference for the advancement of treatment technologies that effectively address both dysfunctions and enhance clinical outcomes.Read more

For me personally, high technologies in pediatrics are not just new opportunities for solving regular professional problems.

This study examined upper limb kinematics under simulated visually impaired conditions. By investigating how upper limb movements adapt in these circumstances, we aimed to gain insights that may prove valuable for both healthy populations and those with clinical conditions. Data, including 3D marker-based motion captur...e and accelerometer readings, were collected from seven healthy volunteers walking on a treadmill at 1.5 m/s under two conditions: without glasses (NG) and with stroboscopic glasses (G). Each walking condition lasted 2 minutes, and two 10-second recordings were analyzed from the midpoint of each session. Contrary to our hypothesis, simulated visual impairment with stroboscopic eyewear at 6Hz did not statistically affect upper limb kinematics, specifically in terms of wrist acceleration and hand distance in the frontal plane. Future research should explore varied visual impairment conditions, extend task durations, and investigate the relationship between subjective gait difficulties and biomechanical data.Read more

Economists often provide predictions about future interest or policy rates. In contrast to stock market predictions, these forecasts are typically regarded seriously and presented with a degree of accuracy. This paper explores whether placing more confidence in policy rate predictions than stock market predictions is r...easonable. It begins by examining historical policy rates predictions in Sweden, comparing them to actual rates to assess their accuracy. The paper then delves into the discussion of how costs of mispredictions, such as sudden and unexpected policy rate increases, can and should be addressed. Despite the Central Bank making predictions within confidence intervals and the banking sector regulating individuals’ borrowing, the burden of unpredicted rate increases falls almost entirely on individuals. The paper addresses whether that is reasonable.Read more
