20. EQUATORIAL BIG RACE

The equatorial (or Australo-Negroid) large race is characterized by dark skin coloration, wavy or curly hair, a wide nose, a low average nose, a slightly protruding nose, a transverse nostril, a large oral fissure, and thick lips. Prior to the era of European colonization, the habitat of the representatives of the equatorial great race was located mainly south of the Tropic of Cancer in the Old World. The large equatorial race is divided into a number of small races:

1) Australian: dark skin, wavy hair, abundant development of tertiary hair on the face and body, very wide nose, relatively high bridge of the nose, average cheekbone diameter, above average height and tall;

2) veddoid: poor development of hairline, less wide nose, smaller head and face, smaller stature;

3) Melanesian (including Negritos types), unlike the two previous ones, is characterized by the presence of curly hair; in the abundant development of the tertiary hairline, strongly protruding superciliary ridges, some of its variants are very similar to the Australian race; in composition the Melanesian race is much more motley than the Negroid;

4) the Negroid race differs from the Australian and Vedoid (and to a much lesser extent from the Melanesian) by a very pronounced curly hair; it differs from the Melanesian in greater thickness of the lips, a lower nose bridge and flatter bridge of the nose, somewhat higher orbits of the eyes, little protruding brow ridges, and, in general, higher stature;

5) the Negril (Central African) race differs from the Negroid not only in its very short stature, but also in the more abundant development of the tertiary hairline, thinner lips, and a more sharply protruding nose;

6) the Bushman (South African) race differs from the Negroid not only in its very short stature, but also in its lighter skin, narrower nose, flatter face, very flattened nose bridge, small face size and steatopygia (deposition of fat in the gluteal region).

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 ... >>

The level of mercury will show the mobile phone 19.02.2013

Chemists from the University of Burgos (Spain) have developed a technology that allows using a mobile phone to detect and assess the level of environmental pollution with the most dangerous toxic metal.

Scientists have made a special membrane plate based on the fluorescent organic compound rhodamine. This substance does not dissolve in water, but the scientists managed to turn it into a hydrophilic polymer that absorbs water and turns red when in contact with mercury. Thanks to the modified rhodamine, the fact of mercury contamination can be seen with the naked eye. Moreover, when photographing the membrane with a mobile phone, the mercury concentration can be accurately determined. Thus, scientists managed to create a simple and reliable way to identify toxic material.

The importance of this development cannot be overestimated. Mercury is a problem that particularly affects developing countries. Toxic metal released into the environment by industrial enterprises, especially mining, accumulates in the brain, kidneys and causes severe neurological diseases. At the same time, mercury pollution is on the rise. In particular, in the world's oceans over the past century, the concentration of mercury has increased by 25%.

An important feature of the invention of Spanish scientists is the ability to fine-tune the mercury "litmus test". The rhodamine strip can be made to respond to a specific concentration of mercury, such as a sanitary one. At lower concentrations, the strip will not change its color.
