The Psychological Effect of Popular Media on the Increase of Crime Over time‚ it has been observed that people have a tendency to learn from the world around them and from the people they interact. The phenomenon of learning within a social context by observation can be termed as social learning. Most individuals tend to observe and replicate the behavior of things with which they come in frequent contact and this is more likely to occur if their feel an emotional attachment with the object

Effect of physical training on the capacity to secrete epinephrine M. Kjaer and H. Galbo +Author Affiliations 1. Department of Medical Physiology B‚ Panum Institute‚ University of Copenhagen‚ Denmark. Abstract Epinephrine responses to hypoglycemia and to identical relative work loads have been shown to be higher in endurance-trained athletes than in untrained subjects. To test the hypothesis that training increases the adrenal medullary secretory capacity‚ we studied the effects of

Part B: Practical Report The Effect of Temperature on Enzyme Activity Aim: To investigate how temperature effects the enzyme catalase. Hypothesis: If the temperature of water is increased then the enzyme will react quicker to form oxygen and water‚ when compared to cold water. Purpose: To design and conduct a plan of a practical about the effects of temperature on enzymatic activity with a partner. Introduction: An enzyme is a protein‚ which speeds up a specific chemical reaction without altering

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

of the drag force on a circular cylinder. The devices used in this experiment were a fan‚ closed-channel venturi-shape pipe‚ a Pitot tube‚ circular cylinder with holes of different angles‚ U-tube manometers and a barometer. INTRODUCTION When a fluid is passing through an object‚ it produces a total force on the object. This force is a combined force of lift and drag forces (Anderson 2007). External flows past objects have been studied extensively because of their many practical applications. For

Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature

Fluid Catalytic Cracking Fluid catalytic cracking* (FCC) is the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling hydrocarbonfractions of petroleum crude oils into more valuable [1][2][3] gasoline‚ olefinic gases and other products. . Cracking of petroleum hydrocarbons for conversion of heavy fractions into lighter fractions was originally done by thermal cracking which has been almost completely replaced by catalytic cracking because
