A stroke is when the flow of oxygen-rich blood to a portion of the brain is blocked. Without oxygen‚ brain cells start to die after a few minutes. Sudden bleeding in the brain also can cause a stroke if it damages brain cells (What is a Stroke‚ 2016). Strokes or Cerebrovascular accidents (CVA) are the fourth leading cause of death in America‚ accounting for five percent of deaths killing over 128‚000 people per year (Kochanek‚ 2016). Over 20‚000 more women than men suffer from CVA (Alan‚ 2013) and

How does pH affect the activity of the Amylase? Abstract: In my experiment I aimed to observe how ranging pH levels will affect the rate in which amylase will break down the starch molecules. I will be measuring the time it takes for the dark liquid to disappear and leave a yellow brown liquid to be shown‚ which would show that there is no starch present in the solution because it would have broken into maltose by adding amylase. Results did not fully demonstrate what we expected in our hypothesis

Compressors are similar to pump‚ both increase the pressure on a fluid and both can transport a pipe. As gases are compressible‚ the compressor also reduces the volume of a gas. Liquids are relatively incompressible‚ while some can be compressed‚ the main action of a pump is to pressurize and transport liquids. Types of compressors The main types of compressors are shown below: Compressor types Positive displacement Dynamic 1. Reciprocating. 2. Rotary 1.Centrifugal. 2. Axial

Biology Lab Report Research Question: Effects of pH on amylase activity Introduction: Amylase is an enzyme that is in human’s saliva as well as the pancreas. Enzymes are biological catalysts that speed up a chemical reaction. They break down complex molecules into simple ones. In this case‚ amylase converts starches (complex molecule) into simple sugars. That is why foods like potatoes for example‚ may taste sweet to us‚ because they contain starch. The optimum pH for pancreatic

Studying locally or studying abroad is better? Going overseas for a university education excites lots of people. But‚ we cannot deny the fact that it has both advantages and disadvantages for students who go overseas for a university education. However‚ it is strongly disagreed that studying locally is better than studying abroad because by studying overseas‚ students can gain new knowledge about other country and it trains them to be more independent.

Modeling Queuing Phenomenon at Petrol Pumps -A Case Study of Bharat Petroleum Rakesh Kumar Lecturer School of Mathematics Shri Mata Vaishno Devi University‚ Sub Post Office‚ Katra-182320 (J&K)-INDIA Abstract The queuing problems are more frequent everywhere. A significant amount of time and resources are wasted if we do not have a suitable mechanism to deal with the rising congestion/queuing problems. This study is a part of a consultancy project which is undertaken at Bharat Petroleum. The problems

When I was a high school student‚ I thinked that studying in high shool was similar to study in college.After graduating high school‚and being a college student‚ I find down how different they are. High shool and college are alike but also different in a lot of ways. There are many reasons why studying in high school is extremely different from studying in college. The first difference is the way of studying.In high school‚ students are taugh for what responsibilities they have and students

formed‚ which is a six stroke engine. Lot of research works are conducting on this topic nowadays and already six types of six stroke engines were discovered yet. Of these the resent developed three six stroke engines‚ i.e.‚ Beare head‚ Bruce crowers and Velozeta’s are undergoing tremendous research works. During every cycle in a typical four stroke engine‚ piston moves up and down twice in the chamber‚ resulting in four total strokes and one of which is the power stroke that provides the torque

during his/her study session and the individual’s study habits showed that the main effect of drinking caffeine on exam preparation was not significant There were participants‚ 20 male and 58 female college students (N=78)‚ answered self-ratings on their personal consumption of caffeine as well as their study habits when preparing for a test/exam. It was hypothesized that the more caffeine a student consumes while studying‚ the more accurately his or her study habits would be labeled as ’unhealthy’‚ as
