1: List the basic steps in securing an operating system. Assume that the O.S. is being installed for the first time on new hardware. Solution An OS allows different users to access different resources in a shared way. The OS needs to control the sharing and provide an interface to allow the access. Each layer is impotent to attack from below if the lower layers are not secured appropriately. The top four assessments for securing os are: Most important thing in securing operating system is to secure a base operating system. The following are the simple steps:.

A blood clot had been silently forming in Adam Parker\'s left anterior descending coronary artery. The 53 year old advertising executive arrived at the Greenville Convention Center feeling fine, but suddenly a dull ache started in the center of his chest and he became nauseated. At first he thought it was the after effects of the convention banquet the night before. When the chest pain persisted, he thought of his family history of heart disease and took an aspirin remembering a radio ad that said to do this if you were having symptoms of a heart attack. Adam then went to the Center\'s Aid Station m not feeling well\" he told the emergency medical technician (EMT). The EMT, on hearing Adam\'s symptoms and seeing his pale, sweaty face immediately thought of a heart attack. \"let\'s get you over to the hospital and get this checked out\" When people speak of a \"heart attack\" they are actually referring to a clot that stops the blood supply to part of the heart, creating a condition known as ischemia In medical terms, a heart attack is called a myocardial infarction (MI), referring to an area of heart muscle that is dying because of a lack of blood supply. The clot in Adam\'s coronary artery had reduced the blood flow to part of his left ventricle and the myocardial cells were beginning to die from lack of oxygen. When someone has a heart attack immediate medical intervention is critical. In the ambulance the EMT gave Adam oxygen, hooked him to a heart monitor and started an intravenous (IV) injection of normal saline (isotonic). With an IV line in place other drugs could be given rapidly if Adam\'s condition worsened. Solution Myocardial infarction leads to congestive heart failure and sudden cardiac death. Oxygen supplimentation given to improve the blood oxigen saturation. In myocardial infarction there is less release of oxigen from heamoglobin leads to tissue hypoxia.the inhalation of 100% oxigen at high barometric pressure, called hyperbaric oxygen therapy.this causes increased the amount of dissolved oxygen in plasma. Which is useful to relieve from ischemia. The osmolarity is the number of osmoles per litre of solution. The solution that have same osmolarity as plasma are said to be isotonic.e.g. 0.9% sodium chloride solution. We know that, when RBC are placed in isotonic solution, they remain suspended in it, neither swell nor shrink because the osmotic pressure of isotonic solution is equal to the osmotic pressure within the RBCs. Hence, by injecting the istonic saline only extra cellular fluid volume Increase.the intra cellular fluid volume and body osmolarity remains same. Since injecting fluid is isotonic it cannot cross the membranes..

What is a SIFI and how does it related to “too big to fail”? Describe the “too big to fail” debate. Solution SIFIs (Systematically Important Financial Institutions) are the financial institutions which are the important part of the economy and the failure of these institutions result in economic and financial crisis. When the financial institutions are very large in size that its failure may result in huge financial crisis, the government take necessary steps to provide necessary strength to the institution that it may not fail. The main motive of SIFIs rules was to cater to the systematic risks and the moral hazard problems of the institutions which were seen in the markets as “too big to fail”. The SIFIs were also called as banks which are too big to fail. Around 29 banks were categorized as SIFIs. The regulations led to higher incentive for the banks to take risks. The government decided to bail out the creditors to prevent the economy after financial failure. The institutions become too leveraged and go for more credit, maturity, and liquidity. SIFI plan includes additional loss absorption capacity, greater supervision, and institution specific cross border cooperation agreements etc. The too big to fail banks supports the economy but also have lot of risk for the financial failure having devastating impact on the economy. During 2008 crisis, the government bailed the creditors to save the banks from failure. This helped the banks to strengthen its condition and improve the profitability. These institutions had capacity to serve the customers throughout USA and with the low costs because of their huge size. This has resulted in the growth in the economy..

Examine the issue of insider trading Analyze the ethical issues at stake (be sure to look at the issue from both Utilitarian and Kantian perspectives). Do you believe insider trading is ethical? Why or why not? Be sure to support your position with reasoned argumentation (including showing why the alternative positions are ethically weaker than your own) Write a critical essav (either in sunnort of Previous Next Dashboard Calendar To Do Notifications Inbox Solution Answer ) Insider Trading and Business Ethics Many people are complaining insider trading since it is unfair for some people who do not have confidential information about a certain company. People who do not have information that is not yet into the public lose their confidence and trust towards the company. Therefore, many companies lose potential investor from insider trading. Insider trading is a huge issue among people. Insider trading can be an unethical; yet sometimes it can be ethical. What is Insider Trading :Insider trading is a word that has many definitions and connotations and which includes both legal and illegal activities. It can also be described as an insider trading of a company’s stock, securities, bonds and stock options by persons with possible access to non- public information about the company. Nevertheless, insider trading can take place lawfully every day, when trading by the corporate insiders such as officers, directors, employees and large shareholders to buy or sell stock in their own companies if this trading will not be taking advantage of the non-public information and also be within the boundaries of the company’s policies and the rules governing this trading. However, the term “insider trading\" is mostly used to describe a practice in which an insider party trades based on non-public material information gained through the performance of the insider’s obligation at the company, in violation of other relationships of faith and assurance or otherwise when the non-public information was stolen from the company. In other words, insider trading is buying, selling or dealing in securities, bonds, and stocks of a company by a director, manager, or employee of the company who has confidential information that is not accessible to the public. Who is an Insider:An insider is a person who has entrée to the confidential information about a company or corporation that will affect the stock price or might manipulate investors’ decisions. This is “material information\". Moreover, most company executives clearly have important information about the company. For example, the manager of sales knows how much the company has sold and if it rallies, the estimates provided with the investors. Moreover, others who work with the company also have material information; for instance, the accoun.

Summarize the main characteristic of insects Solution 1.Insects are cold blooded and have six legs, 3 main body parts and an exoskeleton. 2. Insects lay eggs and many have four wings. 3.Insects have a tough defensive mechanism known as exoskeleton. Because they lack backbones, they are invertebrates. 4.An insect\'s body has three major body elements, inclusive of a head, thorax and stomach. 5.Insects can live on land, inside the water or both. Most insects have antennae that permit them to the touch, flavor, pay attention and smell. These antennae assist them for meals and danger from predators. 6.Some bugs undergo a entire metamorphosis, meaning they grow into completely one of a kind creatures than they had been in their larval stage. Insects that undergo this change include butterflies, real flies and beetles. 7.Insects that go through an incomplete metamorphosis appearance very just like adults of the identical species, most effective smaller. Cockroaches and grasshoppers undergo an incomplete metamorphosis..

please help in microprocessor course (NO handwriting) What is multi-core processing? How does it help in improving computer performance? Write about the different levels of integrated circuit technologies (such as SSI, MSI, LSI, VLSI, etc.). Give examples of each. Write a detailed report on Intel\'s IC fabrication technology with the help of pictures and diagrams. What is the latest technology Intel is working on for chip making? Solution 8)A multi-core processor is a single computing component with two or more independent actual processing units (called \"cores\"), which are the units that read and execute program instructions. Multi-core processors offer developers the ability to apply more computer resources to a particular problem. These additional resources can be employed to offer two types of advantages, improved turnaround time or increasing throughput. An improved turnaround time example is the processing of a transaction in a point-of-sales (POS) system. The time it takes to process a transaction may be improved by taking advantage of multi-core processors. While one processor core is updating the terminal display, another processor core could be tasked with processing the user input. Increase in throughput can occur in the servers that handle back-end processing of the transactions arriving from the various POS terminals. By taking advantage of multi-core processors, any one server could handle a greater number of transactions in the desired response time. Balancing both improved turnaround time and increased throughput is power utilization. A power budget may be specified for the individual system used on the client end or the collection of back-end servers. The additional performance may lead to space, power, and cooling cost savings as fewer systems would be required to meet a specific level of demand. 9) Small Scale Integration (SSI) where the number of transistors incorporated in a single IC chip is up to 100 and they include basic gates and flip flops. Examples:The 7400 TTL series. Medium Scale Integration (MSI) where the number of transistors incorporated in a single IC chip is from 100 to 1000 and they include logic functions such as Encoders, Decoders, Counters, Registers, Multiplexers and small memories etc. Examples:multiplexer,Decoder. Large Scale Integration (LSI) where the number of transistors incorporated in a single IC chip is from 1000 to 20,000 and they include memories. Examples:CPU Very Large Scale Integration (VLSI) where the number of transistors incorporated in a single IC chip is from 20,000 to 10,00,000. Ultra Large Scale Integration (ULSI) where the number of transistors incorporated in a single IC chip is from 10,00,000 to 1,00,00,000. 10)IC Fabrication Technology – Doping, Oxidation, Thin-film deposition, Lithography, Etch, Lithography trends, Plasma processing, Chemical mechanical polishing Integrated Circuit Fabrication: Mass fabrication (i.e. simultaneous fabrication) of many “chips”, each a circuit .

List some applications of surveying in Geology, Forestry, and archeology Solution Remote sensing in geology is remote sensing used in the geologicalsciences as a data acquisition method complementary to field observation, because it allows mapping ofgeological characteristics of regions without physical contact with the areas being explored. RS and GIS has wide applications in geology, requires good knowledge and expertise in hyper spectral data processing and interpretation and quantitative approaches used in imaging spectroscopy for the determination of material composition. Lithological mapping Structural mapping Geomorphological mapping Mineral exploration Hydrocarbon exploration Sedimentation mapping and monitoring Geo-hazard mapping planetary mapping. There are many forestry applicationsthat remote sensing can be used for. Some of these applications include terrain analysis, forest management, recultivation, updating of existingforest inventories, forest cover type discrimination, the delineation of burned areas, and mapping of cleared areas. In archaeology, survey or field survey is a type of field research by which archaeologists(often landscape archaeologists) search for archaeological sites and collect information about the location, distribution and organization of past human cultures across a large area (e.g. typically in excess of one hectare.

Nancy can paint a house twice as fast as Terry can. They year they worked together it took them 7 days. How long would it take each to paint the house alone? Solution Let x=amount of time it takes Nancy to paint a house Then 2x= amount of time it takes Terry to paint a house Now Nancy can paint at the rate of 1/x houses per day Terry can paint at the rate of 1/2x houses per day Together they can paint at the rate of 1/7 house per day. So our equation to solve is: (1/x)+(1/2x)=1/7 multiply each term by 14x 14+7=2x collect like terms 21=2x divide both sides by 2 x=10.5 days-------Amount of time it takes Nancy to paint a house 2x=2*10.5=21 days----Amount of time it takes Terry to paint a house CK (1/10.5)+1/21=1/7 multiply each term by 21 2+1=3 3=3 Also 10.5*2=21 21=21 Hope this helps.

Meningoencephalitis in a 9-year old boy In 2004, a \"9 year old boy is admitted to the hospital in Northern Italy\" from an illness that included a \"1-day history of fever and persistent headache onthe right side.\" The boy had swum in a small \'swimming hole associated with the po River 10 days before the onset of symptoms.\" \"The region was experiencing an unusually hot summer.\" \"The patient\'s temperature was 38c, total leukocyte count his was 13,780/mm3 his reactive protein level was 1.2mg/L He did not have any symptoms of meningitis and his CT scan was normal.\" -on day 2, he developed a stiff neck and became progressively sleepy. A lumbar puncture revealed a total leukocyte count of 6,800/mm3 with 90% neutrophils. csF smears were Gram-stained and were negative for bacteria and fungi.\" on day 3-the Tuc more than tripled and the creactive protein level increased nearly 10x. The patient was started on \"ceftriaxone and corticosteroids\" and transferred to the pediatric ICU. He was \"lethargic and had a scale of He was treated with acyclovir and mannitol and was ed and mechanically ventilated. An \"EEG showed decreased electric activity with short, focal convulsive seizures. Further testing of the csF and blood was done and did not reveal any viruses, bacteria, or fungi. He continued to decline and \"was pronounced dead 6-days after the onset of symptoms.\" on autopsy-no chronic illnesses were discovered. His brain was swollen, had an abnormal appearance, and showed a massive and diffuse inflammatory infiltrate.\" upon further examination, a high number of neutrophils were found and large clusters of cells that resembled amoeba. \"None of the patient\'s friends and relatives who swam in the same water hole on the same day became ill. Nasal swabs from all of them were negative for amoebas.\" Reference From EID, vol 10, no 10, October 2004 1. What is the diagnosis? Name the pathogen that caused the boy\'s illness. 2. What are the incidence and the fatality rate for this disease? 3. How is the disease transmitted? 4. How would you categorize this pathogen? virulent? zoonotic? opportunistic? Solution Answer: 1. Meningoencephalitis in a 9 year old boy: (1) Autopsy revealed massive and diffuse inflammatory infiltrate characterized by a high number of neutrophils, few large clusters of cells that morphologically resembled amoebic vegetative forms, tentatively classified as Entamoeba or Naegleria. It appears to be a case of primary amoebic meningoencephalitis (PAM) caused by Naegleria fowleri. (2) PAM is a rare disease and fatality rate has remained more than 95%. (3) Naegleria fowleri usually infects people when contaminated water enters the body through the nose. Once the amoeba enters the nose, it travels to the brain where it causes PAM, which is usually fatal. Infection typically occurs when people go swimming or diving in warm freshwater places, like lakes and rivers. (4) Naegleria fowleri can be are free living amoeba and can be categor.

in Measurement Of Chlorophyll of the fractionation of the spinach leaf cells, why is PSII activity measured and not PSI? Solution Photosynthetic electron transport in chloroplasts involves the transfer of electrons from water to NADP+. This process is carried out by two photosystems namely photosystem I and II. PSII transfers electrons from water to plastoquinone and PSI transfers electrons from plastocyanin to NADP+. During the subcellular fraction of chlorophyll from spinach leaves, the measurement of PSII activity is relatively easy to measure in vitro due to artificial electron acceptor such as dichlorophenol indophenol (DCPIP). This can be used to measure the activity of PSII by the change in the absorbance of a reaction mixture..

describe how light moves from outside the eye to the fovea centralis. Name all structures and fluids it passes through and how it is refracted to the retina. Solution FUNCTIONING OF AN HUMAN EYE. Human eye acts as a camera.Eye adjusts amount of light it lets in,focuses the objecs near and far and produces images which is transmitted to the brain. Light enters the trough cornea which acts like lens. The iris of the eye acts as a diaphram controlling the amount of light which enters the eye and the size of the pupil is adjusted which acts as an aperture. Then the light travels through viterous humor, a clear gel like fluid in the middle eye, Then the light travels to the retina a sensitive inner lining of the eye which acts as camera film and converts optical image into electronic signals. The image formed in thr retina is upside down ,The optic nerve transmits signals to the visual cortex of the brain which flips the image right side up and creats one complete image..
