Generations Of Computers and their Evolutions  ? FIRST GENERATION OF COMPUTERS (1949-55) :      The first electronic computer was introduced in 1946 by a team led by Professors Eckert and Mauchly at the University of Pennsylvania in U.S.A.-This computer was called Electronic Numerical.integrator and Calculator (ENIAC). It used high speed vacuum tube switching devices. It had a very small memory and  was designed primarily to calculate the trajectories of missiles.  The ENIAC added two digits in around 200 microseconds and multiplied in about 2800 microseconds.   IMPLEMENTATION OF PROGRAM LOOPS : The first computer was designed and commissioned in 1949  at Cambridge University, U.K. under the leadership of Professor Maurice Wilkes. This computer called EDSAC (Electronic Delay storage Automatic Calculator) used mercury delay lines for storage.      Early in the 1950s, stored programme electronic computers saw commercial manu...

        Accompanying with the recent rise in transcontinental trading and travelling, an imcreasing number of plants have been either intentionally or unintentionally translocated far from their native areas (Khuroo et al., 2007). Intentional translocation includes the introduction of non-native plants for agricultural or ornamental purpose. Those introduced plants often escape from the cultivated places to wild habitat if the environmental condition permits. Unintentional introduction occurs with the small mobile seeds that dispersed by animals or get mixed in import goods (Khuroo et al., 2007; Sharma et al., 2005).            Those translocated plants in the non-native lands, called alien plants (Pysek et al., 2004), have attracted the broad attention from various fields such as biology, ecology and economy. Some alien plants, often cultivated, provide food, fuel, fodder or medicine, whereas others cause negative impacts on a...

What is Cholesterol ? Cholesterol is a fat (lipid) which is produced by the liver and is crucial for normal body functioning. Cholesterol is found in many foods, but we donot require it in our diet because the body can synthesize all we need. Cholesterol exists in the outer laver of every cell in our body and has many functions. It is a waxy steroid and is transported in the blood plasma of all animals. It is the main sterol synthesized by animals - small amounts are also Synthesized in plants and fungi. The word “cholesterol" comes from the Greek word chole, meaning “bile”, and the Greek word stereos, meaning “solid, stiff”.  Functions of cholesterol (How It works in our Body ?) 1. It builds and maintains cell membranes (outer layer), it prevents crystallization of hydrocarbons in the membrane.  2. It is essential for determining, which molecules can pass into the cell and which cannot (cell membrane permeability) . 3.   It is involved in the production of sex hormones...

  The Holy Quran is the word of Allah as transmitted by the Angel Gabriel (Jibrail), in Arabic language through Prophet Muhammad (PBUH) it is regarded as un-translatable since the Arabic language is in separable from its message. It is actually available in many other languages but these versions are regarded as interpretations rather than translations .           Although the Holy Quran is a religious book more than 1400 years old with a total of 6666 verses dealing with many aspects of regular life, about 1000 of those verses are of a scientific nature. There are more than 900 verses in the Holy Quran that can be related to relatively new scientific discoveries, which miraculously are said not to contradict the facts as we currently understand them. It reviews diverse scientific topics such as astronomy, geology, embryology, genetics, biology, archaeology, etc.  The Holy Quran has been revealed for the guidance of mankind and invites the people ...
