UCSD, BIMM 124
Excerpt: ... Pediatr Pulmonol. 2005 Apr 13; [Epub ahead of print] How much do Pseudomonas biofilms contribute to symptoms of pulmonary exacerbation in cystic fibrosis? Vandevanter DR, Van Dalfsen JM. Chiron Corporation, Seattle, Washington. Recent studies suggest that chronic Pseudomonas aeruginosa lung infections in cystic fibrosis (CF) involve anaerobic biofilms, and that these biofilms are the reason chronic infections are rarely eradicated by antibiotic therapy, regardless of the in vitro susceptibility of infecting bacteria. These observations led to the development of an in vitro method for testing antibiotic susceptibility of CF clinical isolates in biofilms (Moskowitz et al., J Clin Microbiol 2004;42:1915-1922) and unearthed an apparent paradox. Antibiotics that remain cornerstones of clinical management of CF pulmonary exacerbations (e.g., beta- lactam antibiotics) appear to have little to no activity at clinically achievable concentrations when tested in vitro against clinical P. aeruginosa isolates growing in b ...

Sheet Sandstone or Isolated Sand Bodies? If these sandstones are equivalent in age, perhaps they are part of a regionally extensive sheet that was later eroded, resulting in the scattered remnants of similar quartzites A sheet-like geometry may suggest a shallow marine environment of deposition Isolated channel-like bodies may suggest deposition in river systems How can we tell without fossils to correlate? Perhaps similarities in composition, texture and sedimentary structures, as we ...

Recent studies suggest that peak bone mass in women is achieved at some time between the ages of 15 and 40. After about age 45, bone loss is gradual in both males and females, but a sharp decrease in ovarian estrogen production has been identified as the cause of more rapid bone loss in women during the first ten years after menopause. ...

Excerpt: ... MINERAL ASSEMBLAGES OF HIGH-PRESSURE, QUARTZ-MICA SCHISTS FROM SYROS , CYCLADES , GREECE Dan O. Breecker Amherst College Amherst, MA 01002 dobreecker@amherst.edu The island of Syros lies within the blueschist belt of the Attico-Cycladic metamorphic complex. The island is underlain by alternating, north dipping marbles, metapelites and acidic metavolcanics, which may be repeated in a greatly thickened sequence of stacked thrust sheets. Metabasite localities dot the island and a mlange zone exists to the north. Recent studies suggest that the island was metamorphosed under blueschist facies conditions at approximately 80 Ma, during the Alpine orogeny (Cheney et al., 2000; Brcker and Enders, 1999). There is also local evidence of a greenschist overprint, widely accepted to be a late Oligocene/early Miocene event. This study concerns the mineral assemblages of samples from an island-wide set of quartzmica schists localities. In most samples, three texturally distinct assemblages have been recognized. The matrix ...

Excerpt: ... A Preliminary Habitat Suitability Analysis for the Restoration of South China Tigers in Hupingshan Reserve, China Rob Mehlich ES212: Introduction to GIS and Remote Sensing Colby College April, 2005 Abstract: The South China tiger, Panthera tigris amoyensis, once roamed the greater part of southern China. However, expanding human populations and other anthropogenic effects have resulted in the extinction of the wild population. The Chinese government has expressed interest in a reintroduction program for this species of tigers. Recent studies suggest that the Hupingshan preserve is potentially a good candidate for a tiger reintroduction program. Hupingshan is located on the border of the Hunan and Hubei provinces in Southern China. This study was a preliminary habitat suitability analysis, for the restoration of South China tigers in the Hupingshan reserve, China. ArcGIS 9.0 was used to develop a model that combined roads, railroads, slope, land cover, park classification, and population density. The tiger hab ...

Excerpt: ... i. P( A B ) j. P( A B ) 1 2. A consumer goods company recruits several graduating students from universities each year. Concerned about the high cost of training new employees, the company instituted a review of attrition among new recruits. Over 5 years, 30% of new recruits came from a local university and the balance came from more distant universities. Of the new recruits, 20% of those who were from the local university resigned within two years, while 45% of those who were from more distant universities did. Suppose that a randomly selected new recruit resigned within two years. (15) b. Define the events involved. c. What is the probability that she was hired from the local university? d. What is the probability that she was hired from a more distant university? 2 3. Because of rising health care cost, many people now favor government-sponsored health care that is available to every one. Recent studies suggest that 45% of American adults favor government-sponsored health care and t ...

seedprod1
Virginia Tech, SOILS 1
Excerpt: ... 2) TSGR = total seed growth rate EFP = effective (seed) fill period ISGR = individual seed growth rate When considering how we might manipulate plants to increase yield, we should look closely for any plasticity or ability to alter the key yield-forming processes. Is it possible to manage plants (by fertility, row spacing, irrigation, etc.) to get them to increase the rate at which they fill seeds (without adversely affecting the number of seeds being filled)? Is it possible to manipulate plants to increase the time over which they fill seeds (without reducing the rate of fill or number of seeds being filled)? If so, we could increase yield. Recent studies suggest s that seed fill rate (ISGR or TSGR) cannot be manipulated by management, but it can be selected for genetically. On the other hand, the duration of seed fill is somewhat under environmental control (and the grower has some control over the environment!). TSGR x ISGR x seed density (g/seed/d) (seeds/m2) Influenced by: Influenced by: gen ...

Excerpt: ... 9.) Eat a carb rich diet for 3 days, and carb feeding during exercise lasting 1-4 hours. 10.) Eat a carb rich diet for 3 days and your muscle glycogen storage will double. 11.) Taking in carbs during performance improves endurances and taking in carbs after performance makes recovery faster. 12.) Concentration, along with the type of carbohydrate in the solution, are determinants in the regulation of the rate of gastric emptying. A solution's caloric content, a reflection of its concentration, might be a major determinant of how quickly it empties from the stomach and is absorbed in the intestine. 13.) Early research showed that sports drinks should have less than 2.5 g of sugar per 100 ml of water to speed their passage through the stomach. However, such a small amount of carbohydrate contributes little to energy reserves. Recent studies suggest that to improve performance, athletes should consume at least 50 g of sugar per hour. Most commercial sports drinks on the market today only contain 6 to 8 g of s ...

Iowa State, NR 26658
Excerpt: ... nny, windy days during the winter when temperatures are above freezing. If the soil is frozen, transpired water cannot be replaced and the tree or shrub suffers desiccation stress (foliage browning and tissue death). Certainly, this kind of winter desiccation can occur in early spring when the foliage is actively losing water and the soil is still frozen, however, researchers have demonstrated that water loss alone in midwinter does not cause foliar browning. Instead, recent studies suggest a complex combination of environmental stresses cause foliar symptoms associated with winter injury on evergreens. Winter browning results from the interaction of injurious minimum temperatures with frequent freeze/thaw cycles, and rapid cooling and thawing rates. These conditions are more apt to be found on portions of the plant that intercept the most sunlight during the winter months, and explains why "browning" or "burning" is usually noticed on the south or southwest sides of evergreens. Therefore, the key to reducing ...

Small magnetic crystals in the glacial rocks align themselves to the Earths magnetic field as the sedimentary rocks form. If they had formed near the pole, these crystals would be oriented nearly vertically; in fact, they are nearly horizontal. For a period in the early 1990s the low latitude location of these glacial deposits was called into question but recent studies suggest that Harland had it right. The most recent paleomagnetic data suggests that in the late precambrian, these land area were arranged as follows (Hyde et al., Nature, 405, 425, 2000): Notice that a number of these glacial deposits are located in the tropics (15S-15N). We know these are glacial deposits (limestone and dolomite) and that some reached the ocean because of the presence of ice-rafted drop stones. How is this possible?
