Impulse Control Disorder General Psychology 11:00-12:15 T/H 11/29/13 What is impulse control disorder? Impulse control disorder is more than just acting on a whim. People with an impulse control disorder‚ a newer form of personality disorders‚ can’t resist the urge to do something harmful to themselves or others (Ploskin‚ 2007). People with these disorders may or may not plan the acts‚ but the acts generally fulfill their immediate‚ conscious wishes. Most people‚ however‚ find their

Adol Condensation Introduction: This reaction is carried out by adding benzaldehyde and acetone into a flask. The product created is a 1‚5-diphenyl-1‚4-pentdiene-3-one‚ which includes two double bonds‚ and two benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be

The Effect of Metal Ions on Lichens Casey Stinnett ESC 1510 October 30‚ 2014 Introduction Lichens are a sybiotic association of fungus (mycobiont) and algae (Pediastrum boryanum . The fungus engulfs the algae‚ then supplies carbs‚ nitrogen‚ and vitamins while the algae photosynthesizes. This unusual relationship enables the lichen to grow in environments where neither fungus nor algae would normally be able to solely survive. They are found on every continent‚ ranging all the way from

Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)
