What causes red-eye in photos?

The flash, located on the same optical axis as the camera, is to blame for the appearance of red eyes in photographs. Its bright light passes through the pupil and is reflected from the choroid that feeds the retina with blood - this is the reason for the red color. The effect is more pronounced in fair-skinned people, as they have a lower concentration of melanin pigment, as well as in children, because their pupils dilate faster in the dark. Keeping the flash away from the lens helps to avoid red-eye.

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 ... >>

Infineon launches 512Mb NAND storage 08.03.2004

Infineon Technologies, together with the Israeli company Saifun Semiconductors, has begun production of flash chips with a capacity of 512 Mbit, NAND compatible type.

The chip is built on the basis of non-volatile NROM memory, based on TwinFlash technology, which allows you to write two bits of information into one cell at once. Thanks to this, the chip size is reduced by 40% compared to technologies in which one cell stores one bit, and the cost of products is reduced accordingly.

The company has already received several orders for the new memory, but neither the names of the customers nor the details of the planned production volumes have been disclosed yet. However, representatives of the company noted that they could increase these volumes if necessary, as they expect good demand for their products.

Gartner predicts the NAND flash market will grow from $3,4 billion in 2003 to $4,4 billion in 2004, with unit prices expected to fall from $11,15 to $8,50. USD. Infineon expects to release flash chips with a capacity of 2005 Gbit by 2.
