Currently, among the ship's power plant (SPP), diesel installation taking pride of place, they are used by approximately 90% of global civil courts-fleet. In the domestic shipbuilding industry more than 95% of vessels under construction are the vessels. Diesel units are equipped with many types of vehicles and fishing vessels of sea and river fleet. The main factors contributing to the widespread use of diesel engines on ships as the main and auxiliary engines are their high efficiency, reliability, service life significantly. As part of Navy ships is a large number of ship internal combustion engines (ICE) various types and grades, which differ both in structure and in performance. GOST 4393-74 * includes common symbols marine, locomotive and stationary diesel engines.

" In the letter grades of diesel engines mean: D-stroke, H – Four-, R – Reverse, C – ship with the reverse clutch, P – with the gear transmission, DD – two-stroke double-acting, K – cross-head, h – supercharged. Figures show, the first facing letters – the number of cylinders in the numerator – the diameter of the cylinder, in the denominator – stroke 2. The number after the shot – the revision number of this type (1, 2, etc.) of the engine. For example, grade diesel 5DKRN5O/110 – 2 means a five-cylinder, two stroke, cross-head, reversible, with the supercharged cylinder diameter 50 cm, 110 cm stroke, the second modification. In addition to signs on state standards, used as factory brand diesel engines.

Ozone Layer

But U.S. researchers at Texas Tech University have discovered a new kind of Amazon ants. I found an ant pale body color, no eyes. It said about the underground lifestyle. In place of the mouth are soft hairy pincers, which scientists believe are designed to chew small invertebrates. Forelimbs developed a much stronger back.

Scientists believe that a new species of ants is the oldest in existence. According to them, it is the same relative modern ants, as the platypus – a modern mammals. Scientists have discovered that butterflies have multiple systems to protect researchers from Cornell University found that the butterflies of the family Arctiidae (or bear), there are two warning systems of predators – a visual and audible. These mechanisms prevent necessary to protect the butterflies. When eating predators Arctiidae poisoning occurs, so that once you try it, they will bypass her side. On the bears hunt primarily bats and birds. At the same birds for hunting use vision, and bats – a rumor.

Scientists have put forward several hypotheses of occurrence of such multi-level security systems. One of them says that the simultaneous effect on hearing and vision to increase the efficiency warnings of one kind of predators. The second hypothesis is that the warning system are formed independently, each against a certain type of predator. Recent studies attest to this second theory. On Earth, marked the International Day for the Preservation of the Ozone Layer on 16 September each year the Earth is the International Day for the Preservation of the Ozone Layer – the 1994 General Assembly proclaimed 16 September the International Day Preservation of the Ozone Layer. Day established in memory of signing the Montreal Protocol on Substances that Deplete the Ozone Layer. It was preceded by the Vienna Convention, which was signed two years earlier. The main purpose of these two agreements is to prevent the destruction of the ozone layer by anthropogenic influences. As is known, ozone protects the earth from ultraviolet radiation, which is the main cause of melanoma and other skin cancers. Annually die from these diseases 66 000 people. For the first time in a decline in the Earth’s atmosphere stratospheric ozone layer that protects the planet from harmful solar radiation, scientists drew attention in the late 60s of the twentieth century. The Montreal Protocol has been to ban the production and consumption of 100 kinds of chemicals that deplete the ozone layer.
