up with the bounded rationality and information overload aspects‚ as well. II. METHODOLOGY If data gathering methodology is considered‚ there are two main alternatives: Quantitative Research (which is mostly acquainted with surveys) and Qualitative Research which can be seen as a methodology type not including quantitative data (Gill and Johnson‚ 2010) (and which covers interviews). These two alternatives widely differ from each other regarding the information collection. With questionnaires

Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques used were in accordance with NMU Professor Dr. D. Becker’s lab manual (ISBN 0-390-53911- 2; McGraw Hill). Changes in protocol or interpretation

Assessment of Catalase Function Lab Introduction The purpose of this lab report was to test and measure the rate of substrate destruction by an enzyme‚ we tested the destruction of hydrogen peroxide by the enzyme catalase. Hydrogen peroxide is a poisonous by product of metabolism that can damage cells if it is not removed. Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide into water and oxygen gas. H2O2 + catalase → H2O + O2 A catalyst is a substance that lowers the

Laboratory #6 Qualitative Tests for Carbonyls: Aldehydes vs. Ketones Introduction Various chemical tests identifying ketones and aldehydes are used in this experiment in order to identify an unknown carbonyl compound. The tests used are: 2‚4-dinitrophenylhydrazone test‚ Tollen’s Test‚ Benedict’s Test‚ Chromic Acid Test‚ aka Bordwell-Wellman Test‚ Schiff’s Test‚ and Iodoform Test. These classification tests provide results based on color change or formation of precipitation‚ which is then used
