Sustainability

– Resolution (d) or dividing the price scale – the minimum amount that may change the weight readings. – Price verification scale (e) – conditional value, expressed in mass units. That's it characterizes the accuracy of the scales. Typically, the operation of e 10d. – GOST24104-1988-2001 GOST24104. Currently, there are two guests, in which all calibrated laboratory scales: GOST24104-1988-2001 and GOST24104, so the choice of weights in addition to accuracy class should be specified and the number of GOST. – Accuracy of weighing – the difference (x – a), where – given a number, which is regarded as an approximate value of a quantity whose exact value is equal to x. For laboratory balances by GOST 24104-2001 error in the measurement range in absolute value should not exceed the limits of permissible error.

The values of n (the number of verification scale, which are defined as LEL / e) and NmPV depending on the accuracy class weights and price verification scale e GOST 24104-2001 are shown in Table: Accuracy en NmPV special (I) any more than 50,000, and 100d high (II) to 50 mg inc. from 100 to 5000 incl. 20d St.. 50 mg of 5000 to an average 50d (III) to 2 g incl. from 100 to 10000 incl. 20d St.. 2d 500 to 10000 incl. 20d weights to certain requirements, regardless of their destination. These requirements can be divided into metrology, operational and health, but for laboratory balances preferred metrological requirements, which determine the quality of work balance. We select the most important of them – this is the accuracy of the weighing sensitivity, consistency and stability of readings. Accurate scales are considered when weighing the testimony they give to the deviation from the true readings within the margin of error. On the accuracy of laboratory balances can be divided into groups: – Analytical – scales with an accuracy greater than 0.1 mg – Precision – scales up from 1 g to 1 mg. You can also select some other properties and abilities: – The sensitivity of the scale – to leave the property equilibrium with a slight change in weight of cargo. In this case, the sensitivity of electronic scales is their discrete nature. – Sustainability – property weights in deriving them from the equilibrium state independently return to its original position after some hesitation. – Persistence of evidence – the ability to give the same testimony with multiple repeat weighings.

Space Roses

Unicorns and roses – it would seem that the combination can be found only in fairy tales. However, NASA Infrared Telescope Facility Wide (Wide-field Infrared Explorer, WISE) has recently received image Rosette Nebula, which is located exactly in the constellation Unicorn. This nebula, shaped like a flower located in our Galaxy and is also known under the less romantic name NGC 2237. It is a huge gas-dust cloud in which stars form. Distance to nebula is (according to different sources) from 4500 to 5000 light years of space in the center of the flower is a cluster of young stars called NGC 2244. The most massive stars emit a huge amount of ultraviolet and generate strong stellar winds that erode the surrounding dust and gas, creating a large central cavity. The radiation also cuts off the electrons from the surrounding hydrogen ionizing it and creating what astronomers call Zone H II, or the same region of ionized hydrogen. Although the Rosette Nebula is too weak (it can not be seen with the naked eye), astronomers like to Cluster NGC 2244, because it can be seen in small telescopes or with help of good binoculars.

It was opened by the English astronomer John Flamsteed with a telescope in about 1690, but the nebula was discovered about 150 years later, John Herschel (who is the son of William Herschel who discovered infrared light). In the image obtained after multiple exposures WISE, also shows a trace of a satellite flying in a light-colored stripes. This image is a combination of four pictures received four infrared detectors WISE in different colors. At the final composite image colors are subject-iconic blue and light blue represent the infrared radiation with a wavelength of 3.4 and 4.6 microns, respectively, and it preimeschestvenno stellar radiation. Green and red wavelengths are shown 12 and 22 microns, which are mainly emitted by the heated dust .

Scientific Journals

A man who has devoted himself to science in the 21st century, a matter of respect. After all, such as it depends on the development progress. Every new scientist – this is the completion of the gold reserves of the state and its people. Associate scientist or professor, seems to know a secret which can not know everything. His mind is developing and growing, giving light and clarity of the universe. We do not know what he was doing in his lab, or what thoughts and challenges keeps in his head, but then he is looking for journal scientific publications, and publishes an article that sheds light on his work, his discovery, his investigation. And he did not tell anyone about the problems that arise when entering graduate school for example, how many nights he did not sleeping and not eating because of sociology, or problems with the publication of articles in scientific journals – how many sites need to be reviewed to find the appropriate scientific journal … For him the important opportunity of the experiment, analysis of these facts, the which ordinary people do not even think.

Here's an example: "Skeletonization fingerprint image 'to you about something speaks? This article was published in a scientific journal and the author awarded the President for deep scientific study. Here it is – a scientist, the real, he is interested in the idea of Skeletonization, and not a reward for it. But for a scientist it is also the bread. It's his job – to make new discoveries and to publish articles to educate others. And magazines scientific publications can help scientists to present their research findings. Publish an article in the journal of scientific publications is a prerequisite for dissertation and capacity to new and emerging excavations in science. To publish scientific works must try to find the one magazine that will not leave at the end of the article content, and value it highly. "The World of Arts" – this magazine, which will take into account all wishes of the author-scientist. To publish the article enough to link to the publication of articles and graduate students and postdoctoral article will be published.

Russian Association Biosphere Reserves

Workshop for the biosphere reserves in European Russia was held in the Volga-Kama National Nature Reserve and Raifsky Mother of God Monastery men. The seminar was organized by the Russian MAB Committee, UNESCO Moscow Office and the Government of the Republic of Tatarstan with the support of the Ministry of Environment and Natural Resources, Republic of Tatarstan and the Volga-Kama National Reserve. Apart from the above The following organizations also attended the meeting: Department of the Protected Areas (PAs) in the Russian Ministry of Natural Resources (MNR), the Biodiversity Conservation Center, Institute for Sustainable Communities, Institute of Ecology and Evolution, Russian Academy of Sciences, Moscow State University, Administration of Zelenodolsk region of Tatarstan Republic, the Grand Kokshaga and Volga-Kama National reserves. The following topics were discussed during the seminar: – Experience in implementing the recommendations of the Seville Strategy and the contribution of biosphere reserves to implement the concept of sustainable development – Establishment of Russian Association Biosphere Reserves and mechanisms to strengthen cooperation within the net biosphere reserves' in the European territory of Russian Federation – Biosphere Reserve – a standard description of the Internet and the expansion of participation of biosphere reserves' in the exchange of information – development of possible joint projects in extra-budgetary support. The results of the meeting were summarized in a resolution in the narrative which says that the Russian biosphere reserves perform the functions assigned strategy Seville. They are effective in the biodiversity and landscape conservation and cultural preservation. Research and environmental Education at a relatively high level. .

Royal Navy

Apparently, they crossed the resulting migration towards the coast near the Uruguayan oil strip width of 30 meters and a length of 20 kilometers. Land pollution is the result of a collision between two commercial ships. When an accident of Greek and Maltese vessel in the ocean has resulted in at least 14 thousand cubic meters of fuel. According to scientists, the number of dead penguins may increase. The country's authorities intend to impose a large fine on the owners, because of ocean pollution that has occurred, resulting in dead birds.

The population of the Magellanic Penguin continues to decline and in our days. Up to 20 dolphins have died off the coast of Cornwall English. According to the Association of British divers, environmentalists, the dolphins are likely to have been thrown ashore in while a strong ebb. Arriving on the scene, rescue workers said they opened their eyes a spectacle it was "just horrible." Five animals have been able to save – the rescuers on the boat had to take them to a safe place and let the sea. The reason for the mass death of dolphins off the coast of Cornwall English teaching could become the Royal Navy.

Autopsy of animals showed no obvious cause of death, so that environmental specialists can talk as long as only hypothetical. At present, ecologists examine whether there were no deaths of dolphins in the area of unusual underwater noise caused by movement of ships or military exercises. At last Week 55 besklyuvyh rare dolphins ashore in Madagascar.
