Modified Winkler method for dissolved oxygen determination Abstract In this study the group has determined the presence of oxygen in sample through a modified winkler method. The amount of oxygen is determined through a series of reaction. A body of water can sustain life if dissolved oxygen is sufficed. Depletions in dissolved oxygen can cause major shifts in the kinds of aquatic organisms found in water bodies. Introduction The amount of dissolved oxygen present in water or wastewater is

Determining the Percent Oxygen in the Air INTRODUCTION: Recent tragedies in coal mines have exemplified the importance for us humans to breathe an adequate amount of oxygen if we are to survive. But what amount of oxygen is adequate? How can we know the amount of oxygen present in what we consider fresh air? The purpose of this experiment was to determine the percent oxygen typically present in air. The conclusion of the test suggested that the concentration of oxygen in the lab at the time

Oil consumption in less developed countries | Empirical study on oil consumption in less developed countries | Abstract: This paper investigates the relation between GDP and oil consumption in a sample of 71 LDC’s. Two outlier countries with a deviating rate of oil consumption are found. Equatorial Guinea has relatively low oil consumption‚ while The Seychelles has relatively high oil consumption‚ in relation to their GDP. After that possible factors that might affect oil consumption are discussed

Structured Report on the Health Benefits of Fruit and Vegetable Consumption. Introduction: The importance of the consumption of fresh fruit and vegetables as a means of preventing disease has been known since at least 1747 when a ships surgeon‚ James Lind carried out an experiment which conclusively proved that citrus fruit prevented scurvy. According to Lind‚ scurvy caused more deaths in the British navy than French and Spanish arms combined. He gave some crew members two oranges and one lemon
