5. POPULATION AND ITS TYPES

Under population (literally - population) is understood as an isolated set of individuals of the same species, characterized by a common origin, habitat and forming an integral genetic system.

According to a more detailed interpretation, a population is a minimal and at the same time quite numerous self-reproducing group of one species that inhabits a certain space over an evolutionarily long period of time. This group forms an independent genetic system and its own ecological hyperspace. Finally, this group for a large number of generations is isolated from other similar groups of individuals (individuals).

Basic population criteria - this:

▪ uniformity of habitat or geographic location (area);

▪ unity of origin of the group;

▪ relative isolation of this group from other similar groups (presence of interpopulation barriers);

▪ free crossing within the group and adherence to the principle of panmixia, i.e., equal probability of meeting all existing genotypes within the range (absence of significant intrapopulation barriers).

The ability to maintain for a number of generations such a number that is sufficient for the self-reproduction of the group.

All of these biological definitions are equally fair in relation to humans. But since anthropology has a twofold orientation - biological and historical, two important consequences can be deduced from the presented formulations:

▪ biological consequence: individuals belonging to a population should be characterized by somewhat greater similarity to each other than to individuals belonging to other similar groups. The degree of this similarity is determined by the unity of origin and territory occupied, the relative isolation of the population and the time of this isolation;

▪ historical consequence: the human population is a special category of populations that has its own characteristics. After all, this is a community of people, and population history is nothing more than the “fate” of an individual human community, which has its own traditions, social organization and cultural specifics. The vast majority of populations have a unique, rather complex and still undeveloped hierarchical structure, subdividing into a number of natural smaller units and at the same time being part of larger population systems (including ethno-territorial communities, racial groups, etc.) .

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 ... >>

GPS beacons for drug bottles 21.05.2014

To catch drug-addicted pharmacy robbers, the US police use all methods available today. Now, instead of a bottle of OxyContin - an opioid analgesic based on oxycodone, which has a very strong pain-relieving effect and is often used illegally by drug addicts - pacifiers with a built-in "gift" from the police will be available at points of sale.

To combat and subsequently quickly catch drugstore robbers, the New York City Police Department (NYPD) decided to supply state pharmaceutical stores with baits - fictitious bottles of OxyContin, in the lid of which a miniature GPS device is mounted. Thus, during the robbery of pharmacies by drug addicted criminals, instead of a real bottle with a drug, the robber will receive an imitation, which, although it does not contain a pill, looks no different from the package with a real drug and even makes a similar sound when shaking conditional pills. And the unsuspecting attacker himself will give out the current location for the police group to arrive at the designated place.

One of the last reported cases of successful practice of this technology was an incident at the HealthSource pharmaceutical store in New York. Then the robber demanded money and a bottle of OxyContin from the sellers. Instead of the latter, he received an analogue with the possibility of GPS-tracking the capacity. Police were able to track down 45-year-old Scott Kato, who robbed a pharmacy, 30 blocks from the crime scene, but he was shot while resisting arrest.

The use of such baits proved to be extremely effective, despite the apparent simplicity of the idea. Since their introduction, 111 drug theft suspects have been caught. Such measures, given the extreme severity of the drug trafficking problem, are a necessary and completely justified step that will deter robbers from trying to take possession of OxyContin to consume or sell the contents of a bottle at $ 80 per tablet.

The New York Times noted that this is the first such case when the police department openly informed about the use of such devices as a means of capturing a villain. This fact, according to NYPD Commissioner Raymond Kelly (Raymond Kelly), should restrain the zeal of criminals from the idea of easy money or the use of a prohibited drug.

The bait bottles will be produced by the same company that develops the real OxyContin.
