Kidney Stones/Renal Calculi

Image
 By:Samsubrat   Kidney stones are common disorders that affect the urinary tract. Kidney stones are hard, pebble-like pieces of material that are formed when your urine becomes concentrated, allowing minerals to crystallize and stick together. Kidney stones usually originate in your kidney. However, they can develop anywhere in your urinary tract, which includes these parts : Kidneys Ureters Urinary bladder Urethra Kidney stones vary in shape and size. They can be as small as grain of sand or as large as pea and some stones rarely grow larger than the size of pea. Kidney stone is considered as one among the most painful conditions. Most kidney stones pass on their own causing little or no pain but large stones may get stuck anywhere in the urinary tract and can block urine flow which is very painful. Most of the kidney stones become lodged in the narrowing sites of ureters and these sites are : Ureteropelvic juction(UPJ)  The Urethral crossing of the iliac vessels and The

How the memory is organised in computer systems(Memory Organization)

Image
  By:Sakib Shabir   Memory:     A memory is the collection of storage units or devices together.The memory unit stores the binary information together in the form of bits. Generally, memory storage is classified into two categories 1.Volatile memory:This loses its data ,when power is switched off. 2.Non-Volatile:This is a permanent storage and does not loses any data when power is switched off.    Memory hierarchy: The total capacity of a computer can be visualised by hierarchy of components.The memory hierarchy system consists of all storage devices contained in a computer system from the slow Auxiliary memory to fast main memory and to the smaller cache memory.As we go from top to bottom speed and cost decreases but size increases. Memory hierarchy is nothing but various labels of memory Auxiliary memory access time is generally 1000 times that of  the main memory ,hence it is at the bottom of the hierarchy The main memory occupies the central position because it is equipped to co

Applications of Computer Graphics in Medical Training

Image
By:Sakib Shabir   Computer graphics have played a significant role in the advance of medicine. Since the mid 1970's, when the first three-dimensional visualizations of Computed Tomography 1 were reported, computer graphics have evolved to aid the medical profession in various aspects such as diagnosis, procedures training, pre operative planning and telemedicine (McCloy & Stone, 2001). The use of computer graphics for medical diagnosis has provided an extraordinary ability to visualize, measure and evaluate structures in a non intrusive manner. One of the most important areas in medicine where computer graphics have had a positive impact is training. Computer graphics provide new methods for learning, as professionals can test their skills in simulators and evaluate their performance in a virtual environment. Whereas traditional training in the medical area involved a great number of dissections in order to correctly learn about the human anatomy, computer graphics have provide
