Pressure Regulators – Design Principles, Types and applications A pressure regulator is a device which controls the pressure of liquids or gases (medium) by reducing a high input pressure to a controlled lower output pressure. They also work to maintain a constant output pressure even when there are fluctuations in the inlet pressure. http://www.novors.com/gas-regulator/low-pressure-regulator/

The answer might actually be a bit more complicated than you would think. Examining the history of the engagement ring will show you that it was originally more about the woman than the man.

Since ancient times, plants have been used as herbal medicines. Ayurveda has a 5000 years old rich heritage of the use of plants in the treatment of various human ailments as alternative medicines. Herbal extracts are primarily added to the cosmetic formulations due to several associated properties such as antioxidant, anti-inflammatory, antiseptic and antimicrobial properties. Even today, people in rural and urban areas depend upon herbs for traditional cosmetics. http://www.xazbbio.com/herbal/

They must be durable, long lasting and resistant to a wide range of temperatures, moisture and chemicals. There are five main materials that conveyor belts are made out of: thermoplastics, metal, rubber, fabric and leather. Plastics include polyester, polyvinyl chloride, silicone and polyethylene. The metals are stainless and carbon steel, and the fabric materials are canvas or cotton. The most popular material is a rubber composite because it is flexible, resistant, smooth and seamless. http://www.xhconveyorbelt.com/chevron-conveyor-belt/

Diesel fuel is priced moderately higher than gasoline, but diesel has a higher energy density, i.e. more energy can be extracted from diesel as compared with the same volume of gasoline. Therefore, diesel engines in automobiles provide higher mileage, making it an obvious choice for heavy-duty transportation and equipment. Diesel is heavier and oilier compared with gasoline and has a boiling point higher than that of water. And diesel engines are attracting greater attention due to higher efficiency and cost effectiveness. http://www.xtengineparts.com/diesel-engine/

India is facing the twin challenge of water scarcity and population explosion. The ongoing water crisis has affected nearly 600 million people and is expected to only worsen: The country's population is touted to increase to 1.6 billion by 2050. The agriculture sector is the largest consumer of water in India. It accounts for approximately 90 per cent of 761,000 billion litres of annual freshwater withdrawals in the country. Per capita consumption of water in agriculture sector ranges from 4,913 to 5,800 kilolitre per capita per year. http://www.yby-irrigation.com/micro-irrigation-system/

Instead of just lifting weights, an amateur bodybuilder in the United Kingdom tried to plump up his arm muscles and by injecting them with Instead of just lifting weights, an amateur bodybuilder in the United Kingdom tried to plump up his arm muscles and by injecting them with coconut oil, according to a new report of the case. But he wound up developing cysts inside his arm muscles from the oil, and because he also used steroids, he ruptured his triceps and needed surgery, the report said. http://www.yycindustry.com/bodybuilding-oil/

The Coil Coating Process: Prepainted Steel And Aluminum Coil coating refers to the process of creating prepainted steel and aluminum. Prepainted steel or aluminum can be found in a high number of household products. From refrigerators to air conditioners and construction material, prepainted steel can be found everywhere. Different coatings can be applied for different demands. http://www.chinawanjintong.com/coated-aluminum-coil/

Some batteries will also provide longer backup than others. The 13.5-kilowatt-hour capacity of Tesla’s Powerwall, for instance, outranks Sunrun’s Brightbox at 10 kilowatt-hours. But those systems have the same power rating, at 5 kilowatts, which means they offer the same “maximum load coverage,” according to WoodMac’s director of solar, Ravi Manghani. “Typically, during a power outage, one wouldn't aim to draw at the maximum 5 kilowatts," a load roughly equivalent to running a clothes dryer, microwave and hair dryer all at once, Manghani said. http://www.combinetech.cn/industrial-vehicle-battery/

Why You Should Absolutely Buy an Electric Motorcycle Most motorcycle owners are in it for the feel of the thing. Wind in your hair, sun in your face, engine moving under you, all that. However, there's now an emerging alternative: electric motorcycles. EV bikes have many upsides, and in many more ways, capitalize on what makes bikes so consumer-friendly. So, the real question is, why not enjoy all the upsides of an EV with the perks of motorcycle ownership on top of it? http://www.dbaoescooter.com/electric-motorcycle/
