Cedar Crest College is a private liberal arts women's college in Allentown, Pennsylvania, in the United States. During the 2006-2007 academic year, the college had 1,000 full-time and 800 part-time undergraduates and 85 graduate students. It also admits male students for evening classes.Founded in 1867, the college is historically tied to the United Church of Christ, though it remains academically independent.Cedar Crest is one of two four-year colleges located in Allentown. Muhlenberg College, a liberal arts college loosely affiliated with the Evangelical Lutheran Church in America, like Cedar Crest, is located in Allentown's West End. Wikipedia.

A system for construction of simple poster-board models is described. The models dynamically demonstrate the symmetry operations of proper rotation, improper rotation, reflection, and inversion for the chemically important point groups D3h, D4h, D5h, D6h, T d, and Oh. The models also clearly show where the applicable point, line, or plane lies in relation to the other symmetry elements. This method is presented for use as a one-period exercise in the laboratory course that traditionally accompanies the third-or fourth-year undergraduate-level (advanced) inorganic chemistry lecture course. © 2010 The American Chemical Society and Division of Chemical Education, Inc.

Like other species of Drosophila, Drosophila pseudoobscura has a distinct bias toward the usage of C-and G-ending codons. Previous studies have indicated that this bias is due, at least in part, to natural selection. Codon bias clearly differs among amino acids (and other codon classes) in Drosophila, which may reflect differences in the intensity of selection on codon usage. Ongoing natural selection on synonymous codon usage should be reflected in the shapes of the site frequency spectra of derived states at polymorphic positions. Specifically, regardless of other demographic effects on the spectrum, it should be shifted toward higher values for changes from less-preferred to more-preferred codons, and toward lower values for the converse. If the intensity of natural selection is increased, shifts in the site frequency spectra should be more pronounced. A total of 33,729 synonymous polymorphic sites on Chromosome 2 in D. pseudoobscura were analyzed. Shifts in the site frequency spectra are consistent with differential intensity of natural selection on codon usage, with stronger shifts associated with higher codon bias. The shifts, in general, are greater for polymorphic synonymous sites than for polymorphic intron sites, also consistent with natural selection. However, unlike observations in D. melanogaster, codon bias is not reduced in areas of low recombination in D. pseudoobscura; the site frequency spectrum signal for selection on codon usage remains strong in these regions. However, diversity is reduced, as expected. It is possible that estimates of low recombination reflect a recent change in recombination rate. © 2014 Kliman. Source

Nutrition in Clinical Practice | Year: 2011

For many years, those who studied renal disease recognized a strong correlation between diet and disease progression. Diet therapy, now referred to as medical nutrition therapy, has long been investigated in the treatment of kidney insufficiency and kidney failure. Given that the kidneys have numerous vital functions, including a primary role in the excretion of waste products and urine, the diminishing effects of aging and disease on the kidney require adaptation of the nutrition consumed. Over the years, numerous theories have evolved as treatment modalities. This article explores the history of dietary management of kidney disease going back to leading researchers including Borst, Giovannetti, and Kopple, along with others. Clinicians have witnessed the historic development of national guidelines and protocols for nutrition treatment of chronic kidney disease and acute kidney injury, leading to improved uniformity among practitioners. Some of the changes in medical nutrition therapy and specialized nutrition support are addressed. © 2011 American Society for Parenteral and Enteral Nutrition. Source

Nursing faculty are seldom viewed as a vulnerable population, yet those who teach nursing are susceptible to physical, psychological, and emotional harm from students, peers, and administrators. Such harm can arise from uncivil or dangerous encounters with students, horizontal violence from colleagues, and abuse of power by administrators. Although faculty vulnerability is a serious issue, strategies exist that can minimize the problem. © SLACK Incorporated. Source

Density functional calculations were performed on N,N′-bis(4′- l-phenylalaninyl)-1,4-quinonediimine, a novel substituted aniline "trimer." This is the second reported symmetric quinonediimine with outer rings derived from amino-acid related structures, the first of which derived from an unmodified, naturally occurring amino acid. Results of the calculations were compared to experimental properties of the herein synthesized trimer. The calculated HOMO levels for isomers of the title compound range from -6.0423 to -6.0178 eV, and the LUMO levels from -3.1794 to -3.1772 eV. The calculated electron affinities range from 2.1509 to 2.1554 eV. The LUMO level is lowest for the syn isomer, and the electron affinity greatest in magnitude for the anti isomer. Compared to the widely-studied amino-capped aniline trimer N,N′-bis(4′-aminophenyl)-1,4-quinonediimine, the title compound has lower LUMO levels and greater electron affinity in both the emeraldine base or emeraldine dihydrochloride (salt) form, suggesting that it might be even more effective in corrosion control applications. Because the outer rings are derived from amino-acid related structures, such molecules, particularly as capping groups for polyanilines, could find use in biomedical applications. © 2012 Elsevier B.V.
