What do you mean by Water Injection method?

The Water Injection way used in oil production is where water is injected back into the reservoir generally to raise pressure and so stimulate production. The Water injection wells are normally found offshore. This Water Injection method is used to raise oil recovery from an existing reservoir- Water is injected to force unrecovered oil out of reservoir rock and into close by oil wells. In general only 30% of the oil in a reservoir can be extracted. With the Water Injection that percentage will be superior and the production rate of a reservoir is guaranteed over a long period of time.

How do Lenses and frames made?

The Lenses are characteristically made from one of three materials. They comprise glass, plastic (usually acrylic), and polycarbonate. Glass lenses have the finest optical clearness and scratch resistance, but are heavier than plastic or the polycarbonate lenses. They can also shatter or break on impact. The Plastic lenses are lighter than glass lenses, but are more prone to scratching. They do on the other hand, offer more resistance to shattering than glass. The Polycarbonate lenses are even lighter than plastic lenses. They are shatter-resistant (but not indestructible) making them apt for impact protection.

The Frames are normally made from plastic, nylon, a metal or metal alloy. Nylon frames are generally used in sports for the reason that they are light weight and flexible. They are able to twist slightly rather than breaking when pressure is applied to them. This flex can also help out the glasses grip well on the wearer's face. Metal frames are generally more inflexible than nylon frames thus they can be more simply damaged when participating in sporty activities, but this is not to say that they cannot be used for such activities. For the reason that metal frames are more rigid, various models have spring loaded hinges to help them grip the wearer's face better. The end of the ear pieces and the bridge over the nose can be textured or have a rubber or plastic material to hold better. The ends of the ear pieces are generally bent so that they wrap around the ear; on the other hand, some models have straight ear pieces. Oakley, for instance, has straight ear pieces on all their glasses.

A general view on Computer

A computer is a machine capable of processing data according to a program — a list of instructions. The data to be processed may possibly represent many types of information counting numbers, text, pictures, or sound. The short definition for COMPUTER is “common oriented machine particularly used for technical and educational research”.

Computers can be very versatile. In actual fact, they are universal information processing machines. As said by the Church-Turing thesis, a computer with a certain minimum threshold capability is in principle competent of performing the tasks of any other computer, from those of a personal digital supporter to a supercomputer. So, the same computer designs have been modified for tasks from processing company payrolls to controlling industrial robots. Modern electronic computers also have great speed and capability for information processing compared to earlier designs, and they have become exponentially very powerful over the years (it is a phenomenon known as Moore's Law).

Computers are obtainable in many physical forms. The original computers were the size of a large room, and such great computing facilities still exist for specialized scientific computation - supercomputers - and for the business deal processing requirements of large companies, in general called mainframes. Smaller computers for personage use, called personal computers, and their handy equivalent, the notebook computer, are ubiquitous information-processing and communication tools and are perhaps what most non-experts imagine of as "a computer". However, the most ordinary form of computer in use today is the embedded computer, small computers used to manage another device. The Embedded computers control machines from the fighter planes to digital cameras.

God and his attributes

God most normally refers to the holy being worshipped by followers of monotheistic and monolatrist religions, whom they accept as true to be the creator and ruler of the world.

Theologians have ascribed various attributes to a variety of conceptions of God. The most ordinary among these consist of omniscience, perfect goodness, omnipotence, omnipresence, divine simplicity, and everlasting and necessary existence. God has also been conceived as being incorporeal, a personal being, the source of the entire moral obligations, and the "greatest conceivable existent". These attributes were all supported to varying degrees by the early Christian, Jewish and Muslim theologian philosophers, including Augustine of Hippo, Al-Ghazali, and Maimonides. Many famous medieval philosophers developed arguments for the existence of God, attempting to fight with the obvious contradictions implied by many of these attributes.
