Cleanliness PETROLEUM

Use of contaminated water with a high content of fuel and lubricants, as you know, a very negative impact on the work of machines and mechanisms, may lead to sudden (especially at low temperatures) failure or premature failure. Therefore, it should be noted that in the process of transportation, refueling, storage tanks in warehouses or in the tanks of vehicles existing fuel quantity of water and solids may exceed permissible levels. This is due to the natural ability of the fuel to accumulate water in contact with air and its pollution of atmospheric dust (including the abrasive nature of

Neutralizes WATER

The pool with trout slipped so-called surface-active agents (surfactants). Slightly, only 1.8 grams per cubic meter of water. Within twelve weeks of almost all the trout were ordered to live long. Some did not survive a few days.

But surfactants — no poison. We face them every day. They are used for ore flotation and cleaning of metals, in the food, chemical, and leather and footwear industry. But most of all surfactants discharged into drains laundry there is now such synthetic detergents and washing powders, wherever they were. Long surfactant molecules include hydrophilic and hydrophobic groups. The last of

About Presnyakov

In 1929, while studying at the school, Alexander Presnyakov proposed to replace the water vapor in the combustion chamber of the turbine kerosene or diesel oil. And in the same year received a certificate from the Kompodiza for the invention of a new turbine and then a patent first in their lives. Now, these are called gas turbine.

A series of new inventions: the ship’s propellers, appliances, improving driving characteristics of vessels. For example, a young inventor was able to significantly increase the speed of model boats, covering his body mucin — the biological «grease» that makes it easier

This dazzling outdoor area features several entertaining spaces for the owners and their guests to enjoy.

The homeowners of this property wanted to create an ideal space for entertaining by the pool. They also wanted to incorporate the latest in water sanitisation, as well as an environmentally-sensitive pool. The swimming pool was constructed to the far rear end of the property on a sloping block. This proved challenging as the existing yard had several areas of different heights. These level changes were overcome by creating large planter boxes and a sunken entertainment area that adjoined the swimming pool. The sunken


ECO-productive cities.

Auroville, a growing international township near Puducherry, known for its efforts in social and environmental sustainability is hosting a three-day workshop on ECO-Productive Cities. Distinguished national and international professionals in the field will share their vision and experiences addressing sustainable resource and waste management in the context ECO-Productive Cities.

Cities today are global ECO-predators, occupying 3-4% of the land surface. They consume 80% of its resources and discharge more wastes. And cities in India are growing, the scale and speed of today’s urbanization is unprecedented. An estimated 400 million people are living in cities today. By 2050 another 500 million

My kochia and higher and more beautiful

I love ornamental shrubs, especially kohiyu. Familiar proudly showed me his half-meter kohiyu growth — a beauty! I thought, and you can grow it even higher? Before the rain fed by a bush conventional potash fertilizers — soon grew kochia, it counts twice!

And plants can give quite any form. I take two wires: steel and knitting. I form a steel frame — for example, a ball or animal figures. This design fetter binding wire. The completed form carefully sit down on the plant and start a haircut. Indescribable beauty!


Do you want to get a cheap and

Dwarf Corys

Dwarf corys are the ideal choice for the classic 24-inch (60cm), 15-gallon (54-L) tank. They are peaceful, active during the daytime, and easy to maintain. They can be reproduced quite easily because they do not eat their offspring.

In short, if you like nano-scale fishes and only have a bit of space you should try dwarf corys. This article introduces the most common species.

Among the more than 400 catfish species of the subfamily Corydoradinae (family Callichthyidae) that colonize the numerous South American river systems, we know a variety of shapes and sizes. They range from the large, bulky species

Summer dawns on Voloshne

Even novice spinning know what to go for pike without durable metal leash — it is almost hopeless. On the line, including the braid, spotted predator straightened quickly and easily. Exceptions, however, are. For example, if you are felled on the edge of her lips. But often it happens so that when fishing for chub, ide, chub and other predators lure unexpectedly attack the pike.

Over a rather narrow bay, framed mixed forest, and over the Voloshney slowly dissipate torn shreds of night fog. Indescribable beauty. Three days in a row with short breaks was boring drizzling rain. All attempts

Large packagings for table apples

Rationalization of methods of mechanization intraindustrial transport and other types of ‘works in horticulture US now widely developed.

One such method — the introduction of so-called large packaging. Initially it was used for the marketing of fruit now — and for dessert apple varieties.

In 1960, Michigan approximately 25% of the crop gathered in large packagings, used in most cases, boxes of 120 XX 120X67,5 centimeters; total height of the box 80 centimeters.

Large packagings of the preferred sizes of the established size of freight wagons in many states: the width of the car can accommodate two drawers, height —

Crayfishes compete for optimal water temperatures

The survival of many animals depends on their ability to compete for resources—food, water, shelter, or territory. But could optimal temperatures be an equally valuable resource for cold-blooded species—and a reason for territorial disputes? Canadian scientists led by Glenn J. Tattersall have observed this type of competition in the Louisiana Crayfish, Procambarus clarkii. When it comes to securing a territory with the right temperature, this crayfish shows behaviors similar to those seen in traditional intraspecific rivalries.

The behavior of the Louisiana Crayfish was recorded with video cameras and analyzed later. The experimental containers (so-called shuttle boxes) were divided in two.
