Premiership Footballer Wants to be A Chemical Engineer
Sunday, October 19, 2008
It's a fact that playing football in Barclay Premier League (BPL) must be very lucrative. However STOKE star Seyi Olofinjana has a different view of it. He wants a new career in the later when he retire from football. He wants to join the oil industry.
The 28-year-old midfielder already has a degree in chemical engineering and wants to top that.
He is paying 12,000 pounds sterling for a distance learning course in subsea engineering with Aberdeen University and hopes to work in the huge oil industry back home in Nigeria one day.
Middlesbrough is not a dream day out for many people — but the chemical plants of Teesside could provide a glimpse into Olofinjana’s future.
He said: "I could be working out on the oil rigs when I’m 35, you never know."
The key thing is to get myself prepared. You need to fall back on something. No matter how well you do in football, it’s not for ever.
Source: The Sun NewspaperIt's very interesting to know that a professional footballer like Seyi have an interest and degree in chemical engineering and looks forward on his new career later. Not a lot of footballer will have radical career plan change like him. Let's just see his new career after retiring from soccer.
My 2 cents: I hope he'll be a successful chemical engineer (and hope to see him wear coveralls and safety helmet...).

Pinch Valve Sleeves
Saturday, October 18, 2008
Many industries use specific valves, called pinch valves, to control fluids, waste water, slurries, abrasives and corrosive chemicals. Pinch valves are constructed of a heavy-duty, rugged pinch mechanism that positions a sleeve. The valve offers maximum durability and ensures precise flow control in many industrial processes.
Inside every pinch valve is a sleeve that is crucial to the performance success of the valve. This sleeve enables a pinch valve to have a bi-directional, drop tight shut off with which to control flow. Most pinch valve sleeves are made of flexible elastomer compounds, many of which resemble rubber in composition and feel. Because a sleeve's composition is crucial to the success of the valve's application, valve manufacturers offer different elastomer options from which the sleeve can be constructed.
The many uses of the pinch valve
Because pinch valves are useful in a wide range of industries, the ability of a purchaser to choose the desired sleeve composition is paramount. Commonly used in the mining industry, a pinch valve's tough construction makes it ideal for use on harsh and abrasive mining slurries. Pinch valves can also be useful in demanding wastewater treatment applications. For example, a pinch valve's accurate, repeatable linear flow control and drop tight, bi-directional shut off make this valve type a good choice for sludge and raw sewage control.
In the power industry, pinch valves are an important component used in lime and ash handling - two tough services commonly found within a power plant. The abrasion-resistant, self-cleaning, and flexible elastomer sleeve of a pinch valve won't scale, bridge, plug or freeze on slurries. Pinch valves can also work in the treatment and handling of corrosive chemicals. Because there is no packing to maintain and no cavities, seats, or cam action to bind valve operation, pinch valves are often used in corrosive chemical applications.
Pinch valves can also be used in pulp and paper mills. Pulp stock, coating and recycled paper lines are some of the most difficult applications for a valve. The flexible elastomer sleeve of a pinch valve are able to withstand these abrasive services. Pinch valves can also be a great asset in food and beverage plants, cement/sand/silica factories, refineries, pneumatic conveying, and scrubbing.
A sleeve elastomer for every application
The multitude of uses for pinch valves require that purchasers be able to choose specific sleeve compositions and styles for various applications. A pure gum rubber sleeve, for example, is not suitable for the handling of strong acids, but might be appropriate for food manufacture or alcohol distillation. The application of a particular pinch valve, including the temperature range to which it will be exposed, dictates which sleeve elastomer a valve customer should choose.
Pure gum rubber sleeves are resilient and abrasion-resistant. They can handle an incredibly wide temperature range, from -50 F to 180 F, and they are extremely flexible, as well as non-marking. They are composed of natural rubber, and are most suitable for organic (or, carbon-based) acids, and mild chemical compounds, including alcohols. Strong acid and basic solutions, oils, and solvents are some of the chemicals that this type of pinch valve sleeve is ill-equipped to handle.
Neoprene pinch valve sleeves are synthetic rubber sleeves composed of chloroprene polymers. They handle a slightly wider temperature range than pure gum rubber sleeves do, working well with temperatures up to 220 F. Neoprene is chemically inert, and works best in the handling of moderate acids and other chemicals. Unlike pure gum rubber, it is strong and resilient enough to handle products containing ozone, as well as some oils and fats. Neoprene is more resistant to abrasion than is gum rubber; however, it can be eroded or weakened by oxidizing acids, ketone, ester, and chlorinated hydrocarbons.
Sleeves composed of chlorobutyl elastomers, or chlorinated butyl rubber compounds, handle major temperature ranges, from -60 F to 300 F. These sleeves are known for their good abrasion resistance and their ability to handle animal and vegetable fats. However, other types of oils are too heavy for chlorobutyl elastomers to handle -- as are solvents, which can break down the rubber.
The trademarked name of nitrile (a triple-bonded carbon-nitrogen compound), Buna-N can be used to make sleeves suitable for -40F to 240 F temperature ranges. These types of sleeves can be useful in chemical manufacture and chemical engineering because they can handle chemicals and solvents. They are not suitable, however, for ozone, ester, ketone, or nitro/chlorinated hydrocarbons. Meanwhile, Hypalon, a trademarked name for a chlorosulfonated polyethylene compound, is used to construct sleeves suitable for temperature ranges between -60 F and 275 F. This durable compound can handle quite strong acids and bases, as well as freon, ozone, alcohol compounds, and alkalines. This type of pinch valve sleeve should not be used with ketone, ester, or various aromatic and chlorinated hydrocarbons. Hypalon resists weathering quite well, however.
EPDM (or ethylene propylene diene monomer) valve sleeves are excellent for use with fats and oils. These valves -- made of the material used to seal vehicle doors, windows, and the like -- can withstand temperature ranges between -60F and 300F. They should not be used, however, to work with mineral oils or solvents. They also weather well. Viton, a type of synthetic rubber used commonly in O-rings, can also be used with animal and vegetable oils, as well as with acids. Though this type of sleeve performs poorly at temperatures lower than -10 F, it performs quite well at temperatures up to 400 F. Viton sleeves also display excellent tensile strength.
Each of the many uses of pinch valves requires careful consideration of the valve sleeve that is most appropriate to the process for which the valve will be used. With the variety of sleeve elastomer options available, it is no wonder that pinch valves are applicable in so many situations and for so many processes.
Red Valve, in Pittsburgh, Pennsylvania, manufactures custom pinch valves, including air operated, control, and manual pinch valves, along with pinch valve sleeves. For more information, visit Red Valve's Web site.

Melamine - What is Melamine?
Monday, October 06, 2008
Melamine combines with cyanuric acid to form melamine cyanurate, which has been implicated in the Chinese protein export."
Melamine adulteration of food products has made other headlines in recent years, including pet food recalls in Europe and the U.S. in 2007. It has also been employed as an additive to cattle feed to boost its nitrogen content, appearing in soy meal, corn gluten meal and cottonseed meal.

For further information or latest update on milk products tainted with melamine issue, please access Food Safety and Quality Division website under Ministry of Health Malaysia. Alternatively, please visit WHO website to better understand about melamine contamination.
To obtain the updated list of milk/dairy products that are not affected by melamine contamination by Food Safety and Quality Division, Ministry of Health Malaysia, click here.
I'm sorry but I'm not able to provide information of the approve milk/dairy product for all countries.
New tests on baby milk powder in China show no signs of melamine. The scandal that broke almost a month ago, is responsible for the deaths of four infants and sickening more than 54 thousand others. (Oct. 6). Source: AssociatedPress (AP).
One child has died and an official said the number of children sickened had risen to 432.
Investigators have detained 19 people and are questioning 78 to find out how melamine was added to milk supplied to Sanlu Group Co., China's biggest milk powder producer, officials said at a news conference. They said some tainted powder was exported to Taiwan but none was sent to other foreign markets.
In Taiwan, authorities seized thousands of bags of Chinese milk powder. The incident reflects China's enduring problems with product safety despite a shake-up of its regulatory system after a spate of warnings and recalls about tainted toothpaste, faulty tires and other goods.
The biggest group of victims is in China itself, where shoddy or counterfeit products are common. Infants, hospital patients and others have been killed or injured by tainted or fake milk, medicines, liquor and other products.
In 2004, more than 200 infants suffered malnutrition and at least 12 died after being fed phony formula with no nutrients. Some 40 companies were found to be making phony formula.
