After an initial lag in 1973 and 1974‚ when large surpluses were saved and invested abroad‚ consolidated public expenditure accelerated rapidly: by 1976 it absorbed the entire oil windfall (Figure 2). By 1977 combined federation and states capital expenditure increased six fold over their 1970 level. Public capital expenditure accelerated so strongly that it alone accounted for the spending of more than half of the entire oil windfall. However‚ Nigeria’s continued failure to improve its ranking

Dear Tetchie By Sylvia L. Mayuga INQ7.net Posted date: May 29‚ 2006 (Editor’s note: Tetchie Agbayani remains a blast of a human being. This article about her‚ published as a column 24 years ago‚ has just been echoed and confirmed by her most recent portrait in Newsbreak) Once in a while someone like you comes up to magnetize the public eye and‚ like litmus paper‚ shows up the acidity or alkalinity in us all. You’d think someone‚ anyone‚ might say‚ “Thank you.” What for? You and the activist

Objectives: This lab examines the alkalinity of Spring Creek at the following sites: Chester County Camp‚ Galbraith Gap Run (at the bridge)‚ Spring Creek at Boalsburg’s Military Museum‚ Spring Creek Park‚ Fisherman’s Paradise‚ Spring Creek at Bellefonte (below Buffalo Run)‚ and Spring Creek at Milesburg‚ to determine how the population expansion occurring in State College has affected the watershed‚ along with how human land use and the area’s lithology potentially affects the creek’s alkalinity

Introduction- Can a filter be made for the polluted water so the water will have a clarity of 0%. If a filter is built for the polluted water‚ then the waters clarity will be 0% and the pH value will be 7. The purpose for this lab is to get the polluted water to a clarity of 0%. Water pollution is playing a major role in today’s ecosystems because the water is becoming unsafe to live in and unsafe to consume. “Water pollution is any physical or chemical change in water that adversely affects organisms”

Procedure: The addition of 4.0 mL cyclohexanol‚ 1.0 mL of 85% phosphoric acid‚ and one boiling chip‚ were all added to a 10 mL round bottom flask that would be attached to the end of an assembled simple distillation set up. A sand bath was placed atop a hot plate‚ and the simple distillation mechanism was lowered into the sand bath with the bottom most piece (the 10 mL round bottom flask) submerged about half way. The distillation process was completed after a sufficient amount of liquid distillate

According to my forensic teams research‚ the evidence sample contained starch. My team was also able to determine that the evidence sample dissolved in water ‚and felt like a powder. Performing different tests helped to determine the ingredients that the evidence consisted of. First‚ my team performed a water test‚ by mixing drops of water with the substances A through E and the evidence sample. The forensics then conducted a vinegar test and an iodine test‚ to test for Co² and starch. Finally‚ a

ANALYSIS OF MOUTHWASH Background Information: Commercial mouthwashes are mixtures of water‚ alcohol‚ dyes‚ flavorings‚ and other compounds. In this experiment‚ you will use gas chromatography to determine the alcohol content of the mouthwash. Since the volumes of alcohol and water are not additive when mixed‚ a calibration curve must be used. It will provide the correction factor needed for alcohol-water mixtures. The calibration curve will be prepared by placing a known amount of alcohol

Hypothesis: If pH is increased or decreased past the enzyme’s optimum pH‚ the number of products produced by the enzyme will decrease because the enzyme will become denatured. Variables: The Independent variable is the pH of the environment. The uncertainty of pH is ± 1. pH is a unitless value. The Dependent variable is the number of products produced. The uncertainty of this this measurement is ± 1 product. In order for this experiment to be controlled‚ many variable were identified and held constant
