4. PHYSICAL ANTHROPOLOGY

Anthropology physical is a biological science about the structure of the human body, about the variety of its forms.

The diversity of a person in time and space is made up of manifestations of a large number of very different features and characteristics.

Anthropological sign - this is any feature that has a specific state (variant), according to which the similarity or difference between individuals is found.

Special sections of anthropology are devoted to the study of genetic, molecular, physiological systems of signs, morphology is studied at the level of organs and their systems, at the level of the individual. The variability of these characteristics is studied at the supra-individual - population level.

The tasks of physical anthropology are the scientific description of the biological diversity of modern man and the interpretation of the causes of this diversity.

Methods of research:

a) morphological;

b) genetic (especially population genetics);

at) demographic (connection of demography with population genetics);

d) physiological and morphophysiological (ecology and human adaptation);

d) psychological and neuropsychological (anthropology and the problem of the emergence of speech and thinking; racial psychology);

f) ethnological (primatology and the emergence of human society and the family);

g) mathematical (biological statistics and its role for all sections of anthropology).

Anthropology explores the historical and geographical aspects of the variability of human biological properties (anthropological features). In terms of its content, it belongs rather to the circle of historical disciplines, and in methodological terms - unambiguously to the field of biology.

Also historically, the division of physical anthropology into three relatively independent areas of study:

▪ anthropogenesis (from the Greek anthropos - man, genesis - development) - an area that includes a wide range of issues related to the biological aspects of human origin. It is the morphology of man, considered in time, measured by the geological scale;

▪ racial science и ethnic anthropology, studying the similarities and differences between associations of human populations of different orders. Essentially, this is the same morphology, but considered on a scale of historical time and space, i.e., on the entire surface of the globe inhabited by humans;

▪ actual morphology, studying variations in the structure of individual human organs and their systems, age-related variability of the human body, its physical development and constitution.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Biofuels: more and cheaper 30.08.2012

The new process, developed by scientists at the University of Illinois, doubles the production of alternative fuels while cutting costs. This discovery should make butanol-based fuel more commercially viable. Scientists have finally found a way to get around the problem areas in the production chain, which previously disappointed the industry and did not allow to increase the production of alternative fuels.

The main problem in the production of butanol using microorganisms (eg Clostridium pasteurianum) is that at a certain concentration, butanol becomes toxic to bacteria. This limits the amount of fuel that can be produced per unit of time in one bioreactor. Accordingly, more equipment is required per ton of fuel, which increases the cost of the final product. The second problem is the high energy consumption for the removal of butanol from the "soup" with enzymes in the bioreactor.

American scientists have solved both of these problems. To do this, the scientists used non-ionic surfactants or copolymers that capture and hold butanol molecules. This allows you to maintain a low concentration of butanol in the bioreactor, which means that the bacteria do not die and continue to produce fuel. In general, the yield of butanol increases by 100 percent or more.

But this is only the beginning of a highly effective process. Scientists also use one of the properties of the copolymer - thermal sensitivity. After heating the enzyme solution with butanol, the first is separated into two layers: rich in butanol and saturated with copolymer. This makes it not only easy to separate the fuel, but also the copolymer can be reused up to three times. At the same time, a 3-4-fold saving of electricity is observed in comparison with modern separation technologies.

Butanol is a very promising type of fuel. It can be produced from waste, but it contains 30% more energy than ethanol. In addition, butanol is less flammable and mixes easily with gasoline.
