Nutrition project 1 - Essay Example Our mouth contains tongue and teeth which helps in mechanical digestion that is breaking down the food into particles, chewing and then swallowing. Next part is oesophagus which is very elastic as well as muscular and helps the food go downward by involuntary contractions of the muscles. Next is stomach, it secrets gastric juices it process the food churn further. Basically protein or fat parts of foods are chemically digested here. As 85% of rice is actually carbohydrate so its absorption is done in the small intestine. Carbohydrates are at first hydrolyzed to monosaccharide. Salivary alpha amylase and ptyalin begins the digestion of starch in mouth. Pancreatic amylase further digests it into small intestine. Starch than breaks down into alpha dextrin which then digested by gluco-amylase into maltose and maltotriose. Disaccharides are also hydrolyzing to monosaccharides by enzymes like maltose, isomaltase, sucrase and lactase which are present in brush boarder of the small intestine . The absorption occurs through the brush boarder epithelium covering villi. Chicken has highest level of protein in it. Where milk and rice also have some amount of protein.Protein digestion is mainly done in two organs of human body. It starts at stomach and end with accomplishment in small intestine. Proteins are made of with complex organic molecules such carbon, oxygen, sulphur, hydrogen, nitrogen and amino acids chain. Digestion initiates at stomach with the secretion of hydrochloric acid and enzyme called pepsin. It breaks protein bonds now individual protein digests by proteases and proteinases which called hydrolysis process. Protein molecule now transform into in its simplest form peptones and proteose. Now they leave the stomach and enter into small intestine. The output of stomach in called chime it is highly acidic in nature. It mixes with alkaline and become neutral in small intestine. Pancreatic digestive enzyme trypsin and chymotripsin

Common Software Vulnerabilities', Database Security, and Attacks Essay

Common Software Vulnerabilities', Database Security, and Attacks on Networks discussion - Essay Example Linux has applications from cars to cameras and Raspberry Pi and the bug could be fatal in Android, IBM machines, and Windows (Johnson, 2011). The primary source of the attack emanates from the web where a hacker could manipulate the bug to add malicious code on websites or to funnel information such as health records or bank details (Fogel, 2013). Shellshock allows the intruder to access each internet-powered device in an individual’s home from very innocuous entities such as smart light bulbs. Rated at ten on the severity check, the only solution to the vulnerability is updating devices with patches by the website and server owners to secure their clients. While antivirus and firewalls are the initial defenses for most organizations, they will not to be able to stop the attacker getting in this way and, therefore, must be advised to obtain operating system updates from software vendors. The bug is believed to have been in existence for 25 years, to its discovery by Linux’s expert Stà ©phane Chazelas. For instance, Apache web server operates Bash in its background in executing tasks such as processing personal data keyed in through online forms. Encryption in databases has worked its way to the top of the priorities list in the current IT sector. Applications and firewalls no longer suffice in protection of data and businesses in the present day’s complex and open IT environments. Complying with a number of regulations and mitigating the risk are the main drivers forcing database encryption onto the security agenda. However, there are some proposed corrections to the challenge. At the moment, businesses are taken by key management, concerning the largest challenges as database encryption. They are also grappling with matters such as a way to seclude security management and databases, controlled usage, key copying and the means to offer the security auditor proof of secure systems (Cherry, 2011). Governments for are insisting on encryption to
