Nowadays, information security is a very important issue and DES cipher is the most used cryptosystem throughout the world to protect data. But since many researchers have been dubious for the lack of disclosure which was due to some trapdoors and hidden weaknesses in the DES [2]. How DES algorithm can be improved to provide more secure services to users? 1. Introduction (Data Encryption Standard) DES which was announced by National Bureau of Standard has been around for more than 25 years [8]....
P -The population that will be examined are male and female patients with a physical status (PS) of I-II requiring general anesthesia for surgery, ages 20-40. I - The intervention being introduced is utilizing Sevoflurane (UltaneĀ®) as the inhaled anesthetic for surgeries requiring general anesthesia lasting less than one hour. C - The comparison group will be those utilizing Desflurane (SupraneĀ®) as the inhaled anesthetic for surgeries requiring general anesthesia lasting less than one hour. O...
Autologus stem cell s are routinely collected from patients suffering with a range of haematological disorders they are routinely stored in liquid nitrogen at -180°C.The stem cell harvest typically arrives in the laboratory after 4pm, as a consequence the collection must be stored overnight at 4°C.A aliquot of sample is used to measure the amount of CD34 positive cells collected using flow cytometry. Embryonic stem cells are considered totipotent due to their ability to generate any...
Cellular respiration, aerobic, meaning occurring in the presence of oxygen occurs in the case of seeds. Respiration is the process by which cells breakdown or oxidize the organic molecule glucose into the lower energy state CO and H O. During this process, energy in the form of ATP is released. For aerobic respiration to occur the extremely electronegative diatomic element Oxygen is required in large amounts. So, when the organism is respirating, oxygen is consumed and CO and H O are...
When we enter the enchanting world of electronics we have pleasant routes. The path we have chosen is the union of electronics & medicine. Though many goals could be achieved when passing through those routes we found our routes as a pleasing one. Let us peep inside the real world of MEDICAL ELECTRONICS. MEMS used in various disciplines of life sciences are referred to as BIO-MEMS. After computers & Information technology, MEMS may be the next technological forte of our country....
The research and developments of the renewable resources become more important for a sustainable developments and tackling issues due to the goal of the creation of a bio-based economy is challenging to agriculture, forestry, chemistry and industry. Currently, biomass palys an important role in the development of sustainable energy die to the abundance availability of this and all the biomass are behave as renewable resources. On the other hand, there natural polymer has been also attracted...
ABSTRACT : Alzheimer's Disease is a neurological disease majorly characterized by "decline in the brain function" and "memory loss".The disease involves mainly three stages.Different chemical factors and possibly genetic factors are responsible for causing the disease.Symptoms can be treated by provision of the sufficient supplements to reduce the risk of the disease.Techniques are also available for the treatment and detection which are being expected to be more advance in...
Pica Disorder is the affliction that causes people to have a sudden urge to consume non-food related items (1). This disorder has baffled scientist for decades, and research has yet to come up with a clear reason or cause (1). Pica disorder can be found in literature as early as Hippocrates, and has been classified by many ancient scholars during the middle ages and Renaissance times (1). Many explorers, missionaries, and colonist have also written accounts about pica disorder in their journeys...
This study was done to assess the renal function in normal healthy individuals with normal serum creatinine levels, on the basis of eGFR and to compare and correlate eGFR obtained by various formulae. The mean eGFR was reduced with increase in age. There was a reduction in eGFR in 44.5% of subjects, with stage 3 chronic kidney disease (CKD) in 5.2% of them as calculated by Modification of Diet in Renal Disease study (MDRD) equation. The eGFR values calculated by MDRD, Chronic Kidney Disease...
An Old World monkey, rhesus macaques, has a resistance to herpes simplex virus (HSV) and the reason being is not known. HSV is a DNA virus that can cause disease in many other animals for various reasons. One of these reasons could be that HSV has three known receptors for attachment. HSV also has about twelve surface proteins that allow HSV entry into several kinds of cells as well as different mechanisms on how to replicate without host interference. Since rhesus macaques seems to...
