Human beings are genetically adapted to conditions of scanty and irregular nutrition. In case of food abundance this advantage turned into a significant part of population’s predisposition to “diseases of civilization”. This conclusion has been made by I.S. Liberman, Doctor of Sciences, based on his own data and findings of other investigators.
Atherosclerosis, type II (insulin-independent) diabetes, primary hypertension, and obesity often accompanying them are called diseases of civilization. Within the last decades, these diseases are found with younger people and are often found with patients at the age over 30. According to some researchers, practically everybody has atherosclerosis of aorta and coronary arteries, their manifestation intensifying with years. Such mass distribution, in fact, pandemic of vascular pathology allows to assume that mankind is predisposed to this pathology in the conditions of civilization. Naturally, the degree of such predisposition varies with different people.
The genotype, which determines disposition to diseases of civilization, was formed at the early stages of the mankind development. Its nutrition was then scanty and irregular, and in these conditions the possibility to eat one’s fill for future use was very important. Excessive fat and carbohydrates were laid in the adipose tissue, and mature adipose tissue was a big advantage, particularly with women, who had to give birth and to nurse children. Men spent a lot of energy on hunting, cattle-raising and farming, therefore, their muscles were better developed. The majority of people did not enjoy abundance of food, and there was certain balance between caloric content of food and energy consumption.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
