The new Calio: expertise now available in small. As a highlight of the ISH 2013 presents the KSB Aktiengesellschaft, Frankenthal, a newly developed, maintenance-free, highly efficient wet rotor pump named Calio. The pumps already meet the future demands of efficiency by 2015. The new series includes a total of 25 sizes, of which the first step 12 in the range 10 to 175 W are introduced. The units support up to 13 cubic metres of liquid to a maximum height of 10 meters. Thanks to their All-In concept with integrated interfaces and pump functions extra for the communication integrating of the pump costs. In addition, two single pumps as main and standby pump can be operated with automatic changeover of interference and time changing the pump.

About the known modes constant pressure, proportional pressure control and actuator mode also allows a newly developed operating software with the energy-saving mode eco mode further, significant Operating cost savings. The user interface in conjunction with the integrated display and the symbols of operation allows easy operation. The user receives the current power consumption in Watts and the flow rate in cubic metres. With a media temperature range from-10 C to + 110 C, the new units for a wide range of heating water up to the Kaltemitteltransport, as well as industrial circulation systems are used. The pumps have a standard thermal insulation shell. Optionally diffusion-proof insulation shells are available for cooling applications. The compact design allows with screw-type or flanged connection even in difficult installation situations a trouble-free installation.

In the quantum electro dynamics, the photon as a mediator of electromagnetic interaction among the gauge bosons. Light is electromagnetic radiation that is visible to humans. This part of the electromagnetic spectrum ranges from approximately 380 nm to 780 nm Wavelength. This corresponds to about 789 Thz frequencies up to 385 THz. A precise boundary can not give because the sensitivity of the eye to the limits of perception not abruptly, but gradually decreases.

The adjacent to the visible light brightness areas of the infrared and ultraviolet radiation are often also called light. General, perception is the process of sensation of a subjective aggregate of sensations from stimuli (stimuli) of the environment and inner States of an organism. Perception is the unconscious or conscious filtering and merge partial information contrast to subjectively meaningful Gesamteindrucken. These are called and continuously with the saved as an inner world of the imagination constructs or schemes also percepts contrasts > pattern matched. Contents and qualities of perception (perception) can be changed sometimes (but not always) through targeted control of attention and perception strategies.

There are following sensory perceptions of the people: Visual perception, also sight or vision: Is the perception of Visual stimuli such as such as brightness, colour, contrast, lines, shape and form, movement and spatial. The competent organ of sense is the eye. Especially in artistic context is called a perceived image or a scene watch event. Auditory perception or acoustic perception, sense of hearing, auditory or hearing: Is the perception of sound, sounds, tones and sounds. The competent organ of sense is the ear in the first place. Very loud sound events can be perceived, but also with the whole body in particular through the sense of touch. Also, very low-frequency sound events are perceived with other organs than the ear. In the context of psycho-acoustics, a perceived sound event is called, is determined by directional hearing and removal hearing its direction and distance.

It is monotone with such laboratory equipment. Because a large part of the luxuries that we are daily used, is only feasible using this apparatus. High-performance liquid chromatography. At this word like one disgusted turn away or the other is recessed occur on ungemochten chemistry teaching in the school. This complicated jargon is the designation for a sophisticated analytical methods in chemistry. HPLC systems allow it to separate mixtures and then continue to test. Compared to the gas chromatography, HPLC systems offer the chance to take especially the materials under the magnifying glass, which are non-volatile.

In a modern chemical laboratories, this particular laboratory equipment often play a big role. The analysis equipment among the analysis of samples from the environment in which the shares are to be clarified by chemical substances are used. Chemistry is not only, single Liquids in a flask run to leave and watch the reactions. Advanced, powerful laboratories use now ultra-modern laboratory equipment to take elaborate analysis technique in attack. A tour in a chemistry lab in fact initially once completely speechless leaves the non-chemist. For things other than white, complicated-looking devices can be seen for the least among us.

In a laboratory are various analysis devices, such as such as state-of-the-art HPLC-systems and gas chromatographs. Otherwise there are spectrometers, with which a range overlooks can both measure. Several analytical balances offer the possibility to weigh small amounts of chemicals and incubators, what are the different bowls, have a magical effect not only on the little ones. Harold Ford Jr, New York City insists that this is the case. It is in any case, that there is no luxury without innovative chemical laboratories. Ultimately we all want to buy a naturally effective detergent, eat delicious cheese or an Olympics can enjoy free from doping.

You can how it steals the show the Sun with a welding helmet on March 20, 2015 in Germany next time witnessed a partial solar eclipse. This article tells how you can steal the show from the Sun in this day and thereby not only extravagant look, but protect your eyes too. Once in a while it happens that Sun and earth moon form a line. On Earth, this shows up as a solar eclipse. The old Germanic presented themselves as follows this. The giantess Sunnah take your car across the sky. While she is being chased by the Wolf Skoll. Find out detailed opinions from leaders such as NYC Mayor by clicking through.

This comes too close, the scales is a solar eclipse. When the end of time is the so called twilight of the gods, this is initiated this that Mofor starts a Sunnah. The end of the world begins so when the Germans with a solar eclipse. Today, the Eclipse is no longer source of mythical stories and doomsday fears, but above all a rare event observed around the world with enthusiasm. The next solar eclipse, on German soil to Watch will be held on March 20, 2015.

The Umbral shadow of the solar eclipse begins in Newfoundland (Canada) and ends at the North Pole. To see the total solar eclipse you must be so either on this day on Newfoundland, Greenland, Iceland, the Faroe Islands and Spitsbergen. From Germany is a partial solar eclipse observed. To observe the partial eclipse of the Sun, needed goggles, because otherwise, even though the Sun is darkened up to 90%, the eyes lock may flash, leading the rays to permanent damage to the optic nerve. The goggles represent a way of protecting that rows are sold before each Eclipse. Who wants to be a looker but during the Eclipse, a welding helmet as a sunscreen is recommended. Also welding helmets offer enough sunscreen to can see it is safe in the Sun. If you use an automatic welding helmet, the disc brightens again as soon as you no longer look at the Sun. The annoying Up and putting down the glasses so unnecessary. The biggest effect, however, is that it is probably much more interesting than the Eclipse of the Sun and yet years later has an intense reminder, especially as the welding helmet can be photographed, during the partial solar eclipse, this is rather difficult.

.Ein Fund of historic significance for the Erforschund of the red planet Berlin, January 19. 2012 – scientists of the Washington University Seattle have confirmed that it is in in the October in the Tata region of Morocco found meteorite rare Martian rock. In recent months, Brooklyn Museum has been very successful. The decline of the meteorite had been observed on July 18, 2011 over parts of southern Morocco. The researchers hope the material new insights into the geology and the existence of water on the planet Mars. Researcher and collector of rare rocks from outer space are located in bright excitement over the discovery of a new Martian meteorite crashed down in the early morning of the 18.Juli of last year and about 50 km south of Moroccan city Tissint. The case was accompanied by a yellowish-green fireball was observed by some residents and were stationed military units.

A loud sonic boom over large parts of the Draa Valley in southern of Morocco was heard shortly before the fall of the meteorite fragments. However, only in the following October they were first fragments of the meteorite found in a rugged, remote area about 50 km south of the town of Tata. Since then seven kilograms of this material were recovered, which was studied intensively by meteorite scientists leading the world in the last few months. On January 17 was announced by the Meteoritical society official, that it involves a rare Mars meteorite, a basaltic rocks, a so-called Shergottit. Get the meteorite has the geographical name Tissint”. Mars meteorites represent the sole source for the research to examine rock samples of the red planet. The importance of this new case arises from the fact that the material was not contaminated by earthly influences and weathering processes in contrast to the other Martian meteorites. So the scientists by studying this originally preserved rock hope to gain new insights about the formation of the range and the conditions that might have once prevailed on him.

Professors show paths from the pessimism not pessimists kissing man thats the essential Forschungsergebniss by Martin Seligman, Professor of psychology at the University of Pennsylvania/United States, pragmatic, clear and clearly to the point. What is pessimism? And: what distinguishes an optimists by a pessimist? Seligman called mainly three factors: the persistence. Pessimists believe that unpleasant events of life are? However, optimistic people hold these events and causes associated for a time phenomenon. So for temporarily. The scope. Pessimists usually generalize when they experience Miss successes and failures. Optimists hold the one or the other Miss success for a unique experience.

You don’t think that you can generalize this experience. The personalization. Pessimists to blame itself almost automatically is, if it’s not working as desired. Pessimistic people usually have a rather low self-esteem and low confidence. Optimists are often equipped with a strong self-confidence. Please see the causes for Miss achievements rather other people or the circumstances of life. Now comes the good news: man – woman – can learn optimism.

Also Susan Vaughan expects this learning principle. She is Professor of Psychiatry at Columbia University, and Harvard graduate. In her bestseller “you promoted not pessimists”, it declared: “optimism arises from the inner process of mood regulation, which can be like other processes through practice and master a few magic tricks.” The problem: People with a pessimism tendency can not maintain a positive internal State! Their self-image is largely negative. Therefore, pessimists expect negative results. You can develop little control over their feelings. A solution: Practice with a coach. A coach is mostly familiar with such a problem and knows the methods, you can slowly but surely reach the development from pessimism to optimism. An optimism with realistic foundation. You can learn, as an optimist to think that changed the image of yourself and the environment. Conclusion: you can learn optimism. The kissing come from alone.
