Comments on the article

High Efficiency Linear Lamps, strictly speaking, are only a variation of ordinary linear lamps. An increase in light output is achieved in them due to a special internal coating of the bulb, which reflects infrared radiation. The heat generated by the filament is thus returned back to the filament and contributes to its additional heating.

As the temperature of the filament increases, the light output of a heat lamp increases. High efficiency lamps have a standard length, but their power is slightly reduced compared to standard models (225-250 and 375-400 W instead of 300 and 500 W, respectively).

Attention! The use of a single quartz glass bulb creates a hazard due to UV radiation from the filament (linear lamps are intended for enclosed luminaires only). In addition, this type of glass is sensitive to the touch of bare hands. The necessary safety measures during operation and handling of lamps are indicated in catalogs and on packaging with appropriate pictograms.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

The first wars in human history 04.01.2005

When did people start fighting among themselves? Archaeologists have studied the remains of ancient human settlements in the Oaxaca Valley (Mexico).

Approximately 3600 years ago, nomads began to establish permanent settlements here with adobe huts. In the largest of the villages, there were more than a hundred inhabitants. As shown by carbon isotope dating, 200-300 years after the founding of these settlements, they began to be surrounded by high wooden fences. And two thousand years ago, many men who lived here began to wear metal helmets. Apparently, somewhere in this period, wars between people began.

The Mexican finds support the theory of the American anthropologist Raymond Kelly, according to which nomadic hunter-gatherer societies had murders but no fights between large groups of people.

When permanent settlements arose, relations between people changed, and the essence of conflicts also changed. The killing of one villager came to be seen as an attack on the entire village, for which the enemies should be avenged. Entire armed crowds began to gather on a campaign against a neighboring settlement. The militancy of the ancients intensified when the prosperity of the villages increased: for the sake of rich booty, it was worth going on a campaign.
