Technology – SF Meet Up

Singapore is known for something extraordinary events such as the law that bans chewing gum, the prohibition on displaying the flag of Singapore unless it is the month of the national day or the poor quality of service in most restaurants. Even so, and despite everything, it is a popular destination among European and North American travellers and the truth is that the city does not disappoint. Visit Sheryl Sandberg for more clarity on the issue. The first step to ensure a safe trip and that does not come from the budget is to find a hostel in Singapore where offer quality accommodation, good services and reasonable prices. The second thing you need to do is choose the most interesting places to visit. Depending on the tastes and budget of each, choices are varied, but here are a list of 5 things that you ought not miss. Singapore Botanic Garden this botanical garden has an area of 52 hectares and includes the national Orchid Garden, a collection of more than 3,000 different species of this flower. There you can also see a small rain forest and a spices garden.

It is a place frequented by both locals and tourists, and every Sunday, the Singapore Symphony Orchestra offers a free concert. Haji Lane Haji Lane is a secondary Street in the Muslim quarter. Although it started as a small shopping street, over time it has become a veritable paradise for shopping lovers. There are those who say that it seems to the Parisian Le Marais area or the New York Meatpacking District. Comparisons aside, a stroll down this street you will see a totally different city’s face. Temple of the relic of the tooth of the Buddha name already explains the reason for the fame of this temple, but the architectural beauty of the building itself is already a genuine motivation to visit the temple.

Admission is free every day of the week from 07: 00 to 19: 00 (must dress in a respectful manner), and inside the temple you can visit, moreover, the Emiment Sangha Museum. The entrance to the Museum is free but donations are more than welcome. Heritage Center of Chinatown if not you like a lot of museums but you want to experience a little culture and history, visit this Center is the best choice. There have been recreated bedrooms, kitchens and streets of late 19th century and early 20th century. Attempts to represent how Singaporeans ancestors settled in the area after a long and hard journey. Its location, a few blocks from the huge skyscrapers, makes it an even more special place. It is open every day from 10: 00 to 19: 00 and the entry is worth about 4. Little India Little India is an ethnic neighborhood located east of the Singapore River where the mixture of colors, smells and sounds is a true delight. In addition, it is the perfect place for lunch because there is an infinite variety of food stalls and restaurants that you are not disappointed. There are those who say that go a Sunday is an error since it is full of Indian workers, Sri Lankan, relief, tourists, for others it is part of the charm.

What kind of fibers the same question? In the first all – of the heat-resistant, able to work for a long time at high or very high temperatures. Then – about hemostoykih that can withstand prolonged contact with the most aggressive chemical environments: strong acids, alkalis and oxidizing agents. And finally, the question is, apparently, of the fibers used in one of the most important areas such as medicine, particularly in surgery and alloplastica. Technique every day increases the demands on heat resistance, heat resistance materials. Two or three years ago, we were not aware of fibers and fabrics, can hundreds of hours working at a temperature of 250-300 , without compromising the strength or failure. And now required for fiber work in more severe conditions – at temperatures above a thousand degrees.

And these synthetic fibers have already been established. True, the "work" as long as they only a few minutes. But the thing that has identified ways to address this complex and very important technical problem. The search for chemists working in this field are focused generally on certain classes of synthetic polymers, especially hetero. Macromolecules of the substances containing aromatic ring, different stiffness – it makes heat-resistant polymer.

On the basis of precisely such polymers, American scientists have created two years ago, polyamide fiber-HT, the temperature "endurance" of which reaches 350-450 C. There are methods for producing fibers capable of withstanding a short time heating to 700-1000 . These macromolecules also have a cyclic structure. But this structure is not characteristic of the source material, it occurs in the fiber at a special treatment. What does this mean? Take, for example, normal poliakrilnitrilnoe fiber. It shrinks and loses its strength even at 150-180 . But start to warm up the fiber, slowly raising the temperature to 250-300 -and structure, and with it the properties of the fiber gradually changed.
