Title: Laboratory 2: Measurement of Biochemical Oxygen Demand (BOD) Objective To determine the amount of oxygen necessary for biological oxidation of wastewater effluent and determine the amount of oxygen required by bacteria while stabilizing decomposable organic matter. Methodology Apparatus ; Biochemical Oxygen Demand (BOD) meter‚ Dissolved Oxygen bottle (DO bottle)‚ pipette‚ Teflon tape‚ dilution water‚ incubator machine. Procedure; Add 300 ml dilute water then take DO reading immediately

EXPERIMENT 11: DETERMINATION OF DISSOLVED OXYGEN IN A WATER SAMPLE (WINKLER METHOD) INTRODUCTION In an alkaline solution‚ dissolved oxygen will oxidize manganese(II) to the trivalent state. 8OH-(aq) + 4Mn2+(aq) + 2H2O(l) －－＞ 4Mn(OH)3(s) The analysis is completed by titrating the iodine produced from potassium iodide by manganese(III) hydroxide. 2Mn(OH)3(s) + 2I-(aq) + 6 H+(aq) －－＞ 2Mn2+(aq) + I2(aq) + 6H2O(l) Sodium thiosulphate is used as the titrant. Success of the method is critically

Obstructive Pulmonary Disease Abstract #1 Copd is at the apex of causes for mortality worldwide‚ with a greater incidence rate than ten years prior; systemic infections are the mainstay of the disease process. Periodontal disease has been vividly studied and the absolute foundation of the multifactorial process restrictive airways. The infection leads to inflammatory responses that perpetuates the diseased state via inflammatory mediators‚ and thus mediating copd. Counter arguments for obesity-related

This assignment will explain the pathophysiology of the disease process chronic obstructive pulmonary disease (COPD). It will examine how this disease affects an individual looking at the biological‚ psychological and social aspects. It will accomplish this by referring to a patient who was admitted to a medical ward with an exacerbation of COPD. Furthermore with assistance of Gibbs model of reflection (as cited in Bulman & Schutz‚ 2004) it will demonstrate how an experience altered an attitude.

Chronic obstructive pulmonary disease (COPD) has become one of the major leading causes of mortality worldwide and the prevalence has increased in the last decades (Konstantikaki et al.‚ 2011‚p. 275; Macedo & Usmani 2009‚p. 39). A report compiled by WHO described COPD will be the third leading of mortality rate in the world by 2020 ( Jain‚ Rohan‚ Sharma & Thakkar 2011‚p.258; Macedo & Usmani 2009. p. 39.It has become a serious economic and social burden in individual‚ family and society/ ( Konstantikaki

Title: Amount of Oxygen‚ Mung Beans (Vigna Radiata) Consume during Cellular Respiration Introduction: Cellular respiration is a catabolic reaction that refers to the process of converting chemical energy of organic molecules into a simplify form so it can be used immediately by organism. Glucose may be oxidized completely if sufficient oxygen is available‚ by the following equation: C6H12O6 + 36 ADP + 36Pi + 6O2(g) 6 H2O + 6 CO2(g) + 38 ATP + heat All organisms‚ including plants and animals

Joseph Priestley Joseph Priestley was chemist who discovered oxygen which the most important air in our life. He was one of the most influential chemists in eighteenth century. He was born in 1733. He was born in Birstall‚ West Yorkshire. His family was successful wool-cloth maker. He lived with his grandmother‚ but he could not live with his mom. He came back to home after his mom died. He suffered from his serious ill. He had good education in language‚ history‚ and education. He was awarded for

COPD Salve Aguilar West Coast University Pathophysiology Dr. Isabelle Tardif August 7‚ 2015 Abstract The case study presents the outcome of smoking that resulted to RS’ chronic bronchitis and chronic obstructive pulmonary disease. His ABGs’ show partially compensated respiratory acidosis as manifested by decreased pH‚ increased PaCO2‚ decreased PaO2 and increased HCO3. RS most likely has the following clinical findings caused by COPD: enlarged right heart along with the signs and symptoms

100 180 100 100 100 Modifications The results from my preliminary experiment show that 100 cm3 of oxygen has been produced in the first 30 seconds.. This reaction is far too quick and will prevent me from analysing the effects different substrate concentrations have on enzymes if I decide to continue. I will therefore lower my yeast concentration to 1%. I will also measure the volume of oxygen produced every 15 seconds‚ instead of every 30 seconds. This will make my results more reliable and allow
