Acid rain not only to blame

Fructose Not to Blame for Weight Gain?

Study selection. Controlled feeding trials lasting 7 or more days that compared the effect on body weight of free fructose and nonfructose carbohydrates in diets providing similar calories (isocaloric trials), or diets supplemented with free fuctose to provide excess energy (hypercaloric trials). Exclusion criteria included trials where fructose was delivered only as sucrose or only as high-fru...

To blame or not to blame: Analysts’ reactions to external explanations for poor financial performance

Managers often provide self-serving disclosures that blame poor corporate financial performance on temporary, external factors. For example, many managers have pointed to the September 11th terrorist attacks and the downturn in the economy as explanations for their firm’s poor performance over the past year. Little is known about how financial analysts respond to such disclosures. Results of an...

Acid Rain

Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater actually has a pH of about 5.6 (acidic).[Recall from Experiment 1 that pH is a measure of the hydrogen ion (H+) concentration.] The acidity of rainwater comes from the natural presence of three substances (CO2, NO, and SO2) found in the troposphere (the lowest layer of the atmosphere). As is seen in Table I, carbon dio...

Folic Acid Supplementation: to Advise or not to Advise?

Acid Rain in Wisconsin

While pure rain is naturally slightly acidic, the higher level of acidity in acid rain makes it a threat to plant and aquatic life and to some manmade materials and structures. The slight natural acidity of pure rain is the result of carbon dioxide in the air dissolving in water to produce a weak carbonic acid solution. This natural acid in rainfall and snowmelt is partly responsible for the lo...
