Can a criminal's set of chromosomes justify his crime?

One of the violations of the sex chromosomes is an extra Y-chromosome in the karyotype (a set of features of chromosomes characteristic of cells of the body of an organism of one species or another) of the cells of the male human body.

The set of sex chromosomes in such men is XYY - instead of the normal XY. Very often these are bright personalities, tall, strong, but uncontrollable, they are characterized by cruelty and a tendency to violence. Many of them are criminals.

A study conducted in one of the Scottish prisons showed that about 4 percent of the men imprisoned in it had an XYY chromosome set, while, according to some experts, this combination of chromosomes occurs on average in one in 3 thousand men. In other words, among prisoners, men with XYY chromosomes are found 120 times more often.

In Australia, in 1968, one murderer was even acquitted on the grounds that he had an XYY set of sex chromosomes and therefore allegedly could not control his actions.

Why did the West get scared of Khrushchev's Kuzka's mother?

Khrushchev's famous phrase "I'll show you Kuz'kin's mother!" at the UN Assembly translated literally - "Kuzma's mother". The meaning of the phrase was completely incomprehensible and from this the threat acquired a completely sinister character. Subsequently, the expression "kuzkina mother" was also used to refer to the atomic bombs of the USSR.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Routers Tenda W308R, W309R, W322U 08.05.2013

The Chinese company Tenda, which has a wide range of network devices, has expanded the class of budget routers with an N-class Wi-Fi adapter with two models W308R and W309R, and also introduced a compact USB keychain W322U, endowed with the same wireless module.

The W308R and W309R routers are housed in the same 172 x 110,2 x 31 mm cases and have similar features, but the older model has some improvements. For example, the W309R has two detachable antennas with a gain of 7 dBi, while the simpler version has 5 dBi fixed antennas. External features include the possibility of wall mounting and side placement of ventilation holes. On the rear panel there are 4 LAN ports operating at speeds up to 100 Mbps, and one WAN with the same performance indicators, as well as a WPS button that combines the functions of resetting and establishing WPS communication. In front are indicators of the operation of the router.

The devices are based on a rather productive BroadCom BCM 5357 processor with a frequency of 500 MHz, 32 MB of RAM and 4 MB of permanent firmware storage. The Wi-Fi 802.1 b/g/n communication module is used, providing wireless data transmission at speeds up to 300 Mbps thanks to a two-channel connection using MIMO technology. WPA-PSK and WPA2-PSK encryption standards are available. Routers support all modern types of Internet connection: PPPoE, static and dynamic IP, PPTP and L2TP. They have built-in DHCP for automatic assignment of IP addresses within the network. Equipped with QoS technology, which allows you to set priorities in the use of the Internet channel for individual programs or connected devices. Devices allow you to work with IPTV.

Routers are managed through a web interface. It supports configuring security filters for ports, MAC or URL addresses. You can change the MTU, MAC-ID of the WAN port and DNS server addresses, as well as manually configure routing. There is a traffic counter, in the same section of the interface, restrictions are set on the speed of the Internet channel or the number of downloads for one user or group. USB-adapter Tenda W322U Wi-Fi 802.11 b/g/n has modest dimensions - 75 x 23,5 x 11,4 mm and allows you to quickly equip your computer with high-speed wireless communication with a declared bandwidth of up to 300 Mbps, using two built-in antennas. WPS technology allows you to establish a secure Wi-Fi connection just as quickly. Supports WEP, WPA and WPA2 security standards and the ability to create an access point.

Testing of the W308R and W309R routers shows that the performance of the platform is sufficient to perform the most complex tasks: when processing thousands of torrent requests, there is no heating, drop in speed, or slowdown in the performance of the web interface. Data transfer over LAN corresponds to the declared characteristics, but the performance of the Wi-Fi adapter turned out to be only at the level of 25 Mbps at a distance of 2 meters and about 10 Mbps at a distance of 10 meters, and the W309R, as expected, showed itself somewhat better . Perhaps some improvements will be made in this area after the release of the updated firmware. The W322U adapter provides a stable connection, and its speed performance is approximately at the level of the described routers.

Tenda W322U is already on sale in Russia at a price of 500 rubles, and W308R and W309R will be available in the near future - the expected cost will be approximately 800 and 1000 rubles, respectively.
