The conventional method to send payloads to Mars is by direct trans-Mars injection (TMI) from LEO. NASA is considering an alternative of fueling large Mars-bound cargo transfer vehicles in cis-lunar space with propellants derived from the Moon by in situ propellant production (ISPP) prior to trans-Mars injection from cis-lunar space. A large team of investigators developed an Evolvable Lunar Campaign (ELC) that defined its strategic objective as follows:"The ELC strategic objective is commercial mining of propellant from lunar poles where ...it will be transported to lunar orbit to be used by NASA to send humans to Mars."Unfortunately, sending Mars-bound vehicles to cis-lunar space prior to trans-Mars injection saves little mass in LEO, unnecessarily includes lunar ISPP, which is costly, complex, and risky, and at the bottom line, has no benefits. The problem is that the amount of propellant needed to go from LEO to cis-lunar space is roughly comparable to the amount of propellant used for direct TMI from LEO, so the lunar-derived propellants only offset a small amount of propellant used to augment Mars Orbit Insertion and Entry, Descent, and Landing, and the amount of propellant required in LEO is almost the same in both cases. The initial mass in low Earth orbit (IMLEO) is not reduced much by utilizing lunar ISPP.At the bottom line, sending Mars-bound MCTV to cis-lunar space adds complexity, cost, and risk and provides essentially no benefits.Read more

This article highlights that the main causes of global warming are related to the production of military weapons. It has also been analyzed geographically and geopolitically that changes in carbon dioxide in the atmosphere under the influence of anthropogenic factors are one of the important factors shaping the “greenhouse effect”.

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 v...arious 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: 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 firefighters 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. Res...ults: 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
