In the future, grid mapping of animal and plant organisms will also play a major role in Mongolia. Based on geographical coordinates, a grid with a resolution of 100 x 100 km was created, which contained 561 cells. Methods and level of current understanding are exemplified by means of two raptors and three mammal species. This establishes a basis for an initial project, which will summarize all breeding occurrences of raptors based on all records, publications, or diary notes. For the first time, the short toed eagle was verified in Mongolia as a breeding bird in 2004. By 2006, ten …

The conversion of farmland near cities to other human uses is a global trend that challenges our long-term capacity to provide food, fiber, and ecosystem services to a growing world population. If current trends continue in the United States, the population will reach 450 million by the year 2050. At the same time, an accelerating change in land use will reduce today’s two acres per person of farmland to less than one acre per person. This is scarcely enough to produce food for our domestic population, without any food available for export – even assuming advances in technology. We need …
Administering The Clean Water Act: Do Regulators Have "Bigger Fish To Fry" When It Comes To Addressing The Practice Of Chumming On The Chesapeake Bay?, Hope M. Babcock
Administering The Clean Water Act: Do Regulators Have "Bigger Fish To Fry" When It Comes To Addressing The Practice Of Chumming On The Chesapeake Bay?, Hope M. Babcock
Georgetown Law Faculty Publications and Other Works
The Chesapeake Bay is one of the country's most productive estuaries. However, for decades the health of the Bay has been declining due in large part to nutrification. Excessive nutrients encourage algal blooms, which lower dissolved oxygen and increase turbidity in the Bay's waters. More than 40% of the Bay's main stern is now dead largely as a result of this problem. The practice of chumming, the discarding of baitfish, usually menhaden, over the sides of fishing boats to attract game fish like striped bass, is contributing to the Bay's nutrification problem because the decomposing chum raises the waters biological …

Clusterin is an extracellular chaperone present in all disease-associated extracellular amyloid deposits, however, its roles in amyloid formation and protein deposition in vivo are poorly understood. The current study initially aimed to characterise the effects of clusterin on amyloid formation in vitro by a panel of eight protein substrates. Two of the substrates (Alzheimer's beta peptide and a PI3-SH3 domain) were then used in further experiments to examine the effects of clusterin on amyloid cytotoxicity and to probe the mechanism of clusterin action. We show that clusterin exerts potent effects on amyloid formation, the nature and extent of which vary …

We have studied the effects of the extracellular molecular chaperone, clusterin, on the in vitro aggregation of mutational variants of human lysozyme, including one associated with familial amyloid disease. The aggregation of the amyloidogenic variant I56T is inhibited significantly at clusterin-to-lysozyme ratios as low as 1:80 (i.e. one clusterin molecule per 80 lysozyme molecules). Experiments indicate that under the conditions where inhibition of aggregation occurs, clusterin does not bind detectably to the native or fibrillar states, or to the monomeric transient intermediate known to be a key species in the aggregation reaction. Rather, it seems to interact with oligomeric species …

Clusterin is the first well characterized, constitutively secreted extracellular chaperone that binds to exposed regions of hydrophobicity on non-native proteins. It may help control the folding state of extracellular proteins by targeting them for receptor-mediated endocytosis and intracellular lysosomal degradation. A notable feature of secreted clusterin is its heavy glycosylation. Although carbohydrate comprises approximately 20−25% of the total mass of the mature molecule, its function is unknown. Results from the current study demonstrate that deglycosylation of human serum clusterin had little effect on its overall secondary structure content but produced a small increase in solvent-exposed hydrophobicity and enhanced the propensity …

The Climate Engineers: Playing God To Save The Planet, James Fleming
James R. Fleming
As alarm over global warming spreads, a radical idea is gaining momentum. Forget cuts in greenhouse-gas emissions, some scientists argue. Find a technological fix. Bounce sunlight back into space by pumping reflective nanoparticles into the atmosphere. Launch mirrors into orbit around the earth. Create a “planetary thermostat.” But what sounds like science fiction is actually an old story. For more than a century, scientists, soldiers, and charlatans have hatched schemes to manipulate the weather and climate. Like them, today’s aspiring climate engineers wildly exaggerate what is possible, and they scarcely consider political, military, and ethical implications of attempting to manage …

Effects Of Support On The Initiation And Duration Of Breastfeeding, Sara L. Gill, Elizabeth Reifsnider, Joseph F. Lucke

Researchers attempted to increase the initiation of breastfeeding and its duration to 6 months among a group of low-income, Hispanic women through an intervention program which included prenatal education and home based postpartum support. All participants were telephoned after delivery to determine infant feeding method. Duration of breastfeeding was determined by counting the number of days from initiation to the last day the baby was put to the breast. The Bayesian approach was used for the statistical analyses. In the intervention group, the propensity to initiate breastfeeding exceeded that of the control group. Results indicate the intervention group had twice …

Controlled Language: The Next Big Thing In Translation?, Uwe Muegge
Uwe Muegge
Many global organizations are beginning to see the productivity indicators for their translation and localization processes reach a plateau. That’s an inevitable fact even for those organizations that use what’s currently billed as the latest and greatest in translation technology, such as translation memory with automated workflow components or globalization management systems. Even with these tools in place, making content available in multiple languages remains a very expensive and time-consuming proposition. For those looking for ways to reduce the cost of translation to the point where almost all materials that should be translation actually can be translated, controlled language may …

CONTEXT: Current breast-feeding rates fall short of the recommendations set forth in Health People 2010. The Breast-feeding Attrition Prediction Tool (BAPT), administered in the postpartum period, has been useful in predicting breast-feeding attrition. However, assessing a woman's intention to breast-feed prior to birth would identify women at risk for breast-feeding attrition.
PURPOSE: The purpose of this study was to describe a revised BAPT, administered antepartally that measures intention to breast-feed.
METHODS: The BAPT, comprising 94 items on a 6-point Likert-type scale, was translated into Spanish and back-translated for accuracy. The BAPT was then revised by reducing the number of items …
