This small size mains adapter is designed to power a decimeter wave converter or other similar circuits.

Network adapter with galvanic isolation

The main extinguishing element C1 type K73-17. VD1 serves to pre-stabilize the voltage, and thus protect C2 and the bridge diodes from high voltage. Tr1 provides galvanic isolation from the network (it is necessary to isolate the windings well!). The diodes in both bridges can be any low power rectifier or 20 volt switching diode.

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 ... >>

Morality, charity and religion 12.08.2007

Does faith in God contribute to the moral health of a nation?

The data obtained so far by sociologists are contradictory. Thus, a study of the relationship between religiosity and morality in 18 developed democracies, published in 2005 in the American Journal of Religion and Society, argues that the relationship is negative. The degree of religiosity of the population was assessed by the percentage of believers among the respondents, by the proportion of those who declared their unconditional acceptance of biblical information about the origin of the universe and man, by the frequency of church attendance and the frequency of prayers outside the church.

The researchers considered the number of murders, infant mortality, the prevalence of sexually transmitted diseases, the frequency of pregnancies and abortions among underage girls as indicators of the health of society. It turned out that where the population is more pious, all these indicators are higher than in countries with a less religious population. For example, out of 18 countries, the United States turned out to be the most religious, and there are also significantly more murders, and venereal patients, and underage pregnancies.

On the other hand, statistics on charity in the United States, compiled by Professor Arthur Brooks, shows that believers give 30% more money to charitable organizations than non-believers, they donate blood more often, spend their free time on free work in hospitals, shelters or public organizations. A believing American is 57% more likely to help a homeless vagrant than a non-believer.
