Despite the rather large variety of types of houses and garden houses, as well as outbuildings for various purposes, power supply schemes contain a limited number of elements. Everywhere, an introductory device (pipe rack or distribution box), an apartment shield, sockets, switches, etc. are required.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Collective intelligence in insects 29.07.2022

Scientists from Rockefeller University have found that ant colonies behave in the same way as neural networks during decision making. This was done using a new method of analysis, writes sciencedaily.com.

Two researchers, Daniel Kronauer and Asaf Gal, set up an experimental setup to analyze decision making in ant colonies. They tested how the insects would behave in an extreme temperature increase for them.

When each individual ant in the group feels hot underneath, it holds on as usual until the entire colony suddenly changes course. "They run out as one," the scientists say. "It's almost as if they had a large collective mind."

The data obtained during the experiment indicate that the ants combine sensory information with the parameters of their entire group. So they make one decision at all. This process is similar to neural computing, leading to decision making in the same way.

"We first looked at ant colonies as a cognitive-like system," says Kronauer. "This is one of the first steps to understanding how insect communities participate in collective decisions."
