Where did the first and last British soldiers killed in World War I meet?

The last British soldier to die in action in World War I was George Ellison. He was buried near the place of death in a military cemetery east of the Belgian city of Mons.

Coincidentally, Ellison's grave was located opposite the grave of John Parr, the first British to die in this war.

How does an egg develop?

What could be easier than an egg? But his birth is a rather complicated thing. In the belly of a bird, the egg yolk is first formed. It is formed inside a special organ called the ovary.

Once the yolk has formed, it moves into the oviduct. This is where the protein is made. Further, the egg, or rather part of it, moves to the lower end of the oviduct, where a leathery membrane and shell are formed. The egg is now ready to be laid. The shell is quite hard, but has pores. As the liquid content of the egg gradually evaporates through the pores, air enters to supply oxygen to the developing embryo.

The embryo is the part from which the body of the chicken will develop. Inside the shell is a leathery sheath that forms an airy rind at the blunt end of the egg.

It also contains a protein called albumin. It is a tasteless and odorless liquid, jelly-like in appearance, mostly consisting of water. White strands can be seen in the protein. Their purpose is to keep the yolk in the center of the egg, like in a hammock, and keep it from being hit. The yolk itself is round in shape: it is food for the embryo, which is located in a small cavity on its surface. The embryo of a fresh chicken egg is clearly visible if you carefully examine the yolk. And the germ in the eggs of other birds is so small that it is visible only under a microscope.

The size of the egg does not always depend on the size of the bird itself. It depends on the amount of food needed to feed the developing embryo until it hatches from the egg. Birds born blind and helpless hatch from small eggs that didn't have enough food to fully develop until they were born, when they could take care of themselves.

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 ... >>

Biofuels: more and cheaper 30.08.2012

The new process, developed by scientists at the University of Illinois, doubles the production of alternative fuels while cutting costs. This discovery should make butanol-based fuel more commercially viable. Scientists have finally found a way to get around the problem areas in the production chain, which previously disappointed the industry and did not allow to increase the production of alternative fuels.

The main problem in the production of butanol using microorganisms (eg Clostridium pasteurianum) is that at a certain concentration, butanol becomes toxic to bacteria. This limits the amount of fuel that can be produced per unit of time in one bioreactor. Accordingly, more equipment is required per ton of fuel, which increases the cost of the final product. The second problem is the high energy consumption for the removal of butanol from the "soup" with enzymes in the bioreactor.

American scientists have solved both of these problems. To do this, the scientists used non-ionic surfactants or copolymers that capture and hold butanol molecules. This allows you to maintain a low concentration of butanol in the bioreactor, which means that the bacteria do not die and continue to produce fuel. In general, the yield of butanol increases by 100 percent or more.

But this is only the beginning of a highly effective process. Scientists also use one of the properties of the copolymer - thermal sensitivity. After heating the enzyme solution with butanol, the first is separated into two layers: rich in butanol and saturated with copolymer. This makes it not only easy to separate the fuel, but also the copolymer can be reused up to three times. At the same time, a 3-4-fold saving of electricity is observed in comparison with modern separation technologies.

Butanol is a very promising type of fuel. It can be produced from waste, but it contains 30% more energy than ethanol. In addition, butanol is less flammable and mixes easily with gasoline.
