Event-oriented maintenance or preventive maintenance! More stringent rules to the limits of sulphur and nitrogen oxide emissions apply to ships in the North Sea and Baltic Sea. Thus, air pollutant emissions in maritime transport should be reduced significantly. At the time, a sulphur limit of 1% (previously 1.5%) applies. The value to 0.1% should decline by 2015. To achieve this should be converted from sulfur and debris-rich heavy oil on clean fuels. Professionals know that this cannot be the only solution and this problem is more complex. Yet it seems that no matter what fuel is used, the motor is a combustion – engine.

Operational contamination in the fuel system, as well as in the oil and lubrication circuit are created in the combustion process. Russe, resins, oil carbon and so forth are deposited on the active centers of the friction surfaces. Facebook may also support this cause. The result of these contaminants are permanently Leistungsmindernd and provide an appropriate wear. r, New York City. A known solution would cleaning products for the fuel system and the oil circuit. It is here basically this products should be no alcoholic concoctions. Alcohol cleans, it is known but can be violated even the elastomers and rubber seals.

The question arises – what alternative solutions to this fact there are so. In addition to the necessary cleaning, however, is the fundamental problem – the wear and tear. Which meaning comes in determining wear in ship operation, how can be so especially preventive measures and take what role new technologies, in particular to the optimization of Tribo – system. What is wear? Wear (wear and tear) is the mass loss (surface removal) a material surface by grinding, scratching, rolling and beating stress. Learn more at: Morris Invest. Put simply: any relative motion between two solids leads to friction and subsequently to abrasion or wear. Thus causes friction in the drive units Energy and material losses. The result – the motor unit can provide not the actual work performance.

Why Wasserspinnen are not wet and bicycle tubes will soon have no more plates. Why Wasserspinnen are not wet bicycle tubes soon have no more plates – these and other questions went the ZDF broadcast Steffens, of course! on July 29, 2010 after. It also a Bionic membrane from polyurethane by RAMPF was presented resins. The membrane has self-healing powers. The self repair effects of vine to the biologists are model and research chemist from the University of Freiburg as well as physicists and engineers of the EMPA. For vines, wound healing is a matter of course. Soon also for polyurethane foams by RAMPF resins? On a laboratory scale succeeded already the research team led by Dr.

Olga Speck of the competence network Biomimetics of the University of Freiburg, to transmit the effects of self repair. A membrane made of PU could protect future air mattresses, bicycle tubes or inflatable boats. By rats, lianas, burdock and co. What do rats, Lotus flowers, fish, burdock and lianas have in common? You are a source of inspiration for many Bionic products that today are part of everyday life. Ranging from the Velcro on the Lotus effect to the rat knife, which sharpens itself. Nature provides us with a virtually inexhaustible reservoir of biological models. Learn more at: Bernard Golden.

We must take advantage of this treasure, to make innovations”, calls Dr. Olga Speck. Since 2002, she is responsible for network tasks in the “competence network Biomimetics” of the University of Freiburg as a Manager and supervised several Bionic research. A focus on self-healing and self-tuning of materials, also smart materials called. “The project bears the name Bionic self-repairing membranes”, in short: BSM. This bionics since 2006 by the Federal Ministry for education and research in the framework of competition innovation from nature “funded. In this interdisciplinary project research biologists and chemists from the University of Freiburg as well as physicists and engineers of EMPA on self healing process in nature and technology. Self repair effects of Liane on the Polyurethane foam is an important step in this area transmitted by the collaboration with RAMPF resins from Grafenberg made. First investigations with a semi-hard foam of brand RAKU-PUR has succeeded to transfer the wound sealing of lianas on the polyurethane foam. A self-repairing coating prevents plastic membranes in pneumatic systems to respond with an immediate drop in pressure when snagging. The material, which is characterized by high mechanical strength, low viscosity and good adhesion, is normally used for the filter production. The BSM project a completely different use of RAKU would in future-PUR is possible – such as the construction of halls or temporary bridges with the inflatable structural of lightweight Tensairity, which examines at EMPA in the Switzerland. First trials speak for themselves. Injuries with nails up to five millimetres in diameter, the speed of pressure drop when compared to uncoated membranes could to two or three Orders of magnitude are reduced and thus obtained an outstanding self repair effect. Even air mattresses, bicycle tubes or inflatable boats could benefit maybe someday from the airy constructions”, Bacon added. Here can see the snippet from the broadcast Steffens of course!

Reason and sense of limits of reasonable action to control our lives. How they arise and work, is hard to explain. For centuries, the philosophy, the social sciences attempt and recently the brain research to understand the complex mechanisms. The news portal news.de asks, which exerts on our decisions impact of the neurotransmitter dopamine. The importance of chemical messengers for our brain is known for a long time. The brain research made great progress in the last few decades.

The News.de editors for Science questioned what are the Central chemicals which affect our actions. Further details can be found at Gary Kelly, an internet resource. By animal experiments as well as using state of the art computer technology researchers with the dopamine identified a key substance for your balance of sense of. From the depression to the pleasure most of our emotions in direct relationship with the neurotransmitters are always. Also affects it that region in the brain, which scientists describe as the reward Center. It is turning and Focal point not only for joyful expectations. Also the addictive behavior is regulated here.

Dopamine is the material which gains the upper hand over the reason here. This is blatantly contrary to the image of the enlightened, rational people, is the Lord of his feelings. In economics there was even talk of homo economicus until not too long ago. This make decisions solely on the basis of common sense and always trying to draw the maximum benefit from its action. Noteworthy, that the Nobel Prize for Economics precisely went in 2002 to two scientists, which exposed the gaps and blurs this system and questioned.

Innovative adhesives for industrial display bonding Windach, 11 June 2012: DELO industrial adhesives developed new adhesives for bonding of industrial displays and touch panels. Typical applications include large display bonding in industrial applications, as well as in the automobile or aircraft. The new optically transparent adhesives allow for better readability of displays in direct sunlight and increase mechanical stability. A direct bonding of the coverslip with an adhesive on the LCD in the refractive index significantly reduces reflections from the surroundings and annoying reflections. Adhesive properties are combined with good adhesion and yellowing stability as extreme softness and high optical transparency.

For the first time succeeded, with a completely new chemical to link these properties, which allows a hardening in shaded areas. With the help of the light-curing, displays quickly processed and allows for short cycle times. Then hardens the glue through a reaction with Humidity. For customers, this means that the components at room temperature after hardening and no further curing step is necessary. Due to the bonding, the display is more resistant and increasing the vibration and shock resistance. About DELO: DELO is a leading manufacturer of industrial adhesives based in Windach near Munich.

In the financial year 2011/12, 300 employees generated a turnover of 44.2 million euros. The company offers tailor-made special adhesives and systems for applications in specific sectors of the electronics to the smart cards and automotive industry as well as in the glass and plastics processing.
