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 ... >>
Random news from the Archive 34" IPS monitor LG 34UM95 with a resolution of 3440 x 1440 pixels
17.03.2014
LG has started selling the UM95, UM65 and UB65 series monitors in Europe, announced in mid-December last year. Each line includes only ultra-wide monitors based on IPS matrices with an aspect ratio of 21:9.
The flagship model LG 34UM95 is offered in Europe at a price of 999 euros. This monitor is equipped with a 34-inch LCD panel with 3440 x 1440 dots resolution, 320 cd/m1000 brightness, 1:5 contrast ratio, 34ms pixel response time. LG 95UM14 is endowed with a three-port USB hub, two speakers with a total power of 1.2 W, as well as DisplayPort 2 and Thunderbolt 1.4 video inputs and two HDMI XNUMX.
The UM65 series monitors are cheaper. Their cost is as follows: LG 25UM65 (diagonal - 25 inches) - 279 euros, 29UM65 (29 inches) - 449 euros, 34UM65 (34 inches) - 609 euros. The characteristics of their matrices are as follows: resolution - 2560 x 1080 pixels, brightness - 300 cd / sq.m (in LG 25UM65 - 250cd / sq.m), contrast - 1000:1, response time - 5 ms. Each of the three models is equipped with two speakers, two HDMI ports and one DVI.
Simultaneously with the models of the UM65 series, the 29UB65 model went on sale, which differs from the 29UM65 only in the presence of a transformable stand with the ability to rotate the display at an angle of 90 ° (pivot). Price LG 29UB65 - 489 euros.
