Storm Lake, IA, United States

Buena Vista University is a private 4-year college located in Storm Lake, Iowa. Founded in 1891 as Buena Vista College, it is affiliated with the Presbyterian Church. The university's 60-acre campus is situated on the shores of Storm Lake, a 3,200-acre natural lake. BVU's academic programs feature a balance between traditional liberal arts courses and hands-on learning opportunities, such as travel and internships. The university awards its faculty with the $30,000 George Wythe Award for Teaching Excellence, one of the largest faculty awards in the nation. The average student-to-professor ratio is 13:1.At its inception, the college was housed in the Storm Lake Opera House, where it remained for only a year. Old Main, the college's first building, opened in 1892, and was occupied by faculty and students until it burned down in 1956. Major construction projects in the 1950s and 1960s extended the college, which soon included three dormitories, a library, and a number of classroom buildings.The college gained accreditation in 1952, and began to grant degrees under the authority of the North Central Association of Colleges and Secondary Schools. The first graduate degrees were offered in 1995, at which time the college became Buena Vista University.The main campus of Buena Vista University offers a 4-year residential collegiate experience and currently offers classes in 42 majors. Seventeen additional locations throughout Iowa and online serve working adult and graduate students as part of the Graduate & Professional Studies program. The university is ranked in the top 20 Midwestern Comprehensive Colleges, as reported by U.S.News and World Report's college rankings. In 2012, BVU was ranked 9th for academic quality in the Midwestern Baccalaureate category. Wikipedia.

Textured gadolinium nitride (GdN) thin films grown on (100) lanthanum aluminum oxide substrates were prepared by chemical vapor deposition with gadolinium chloride and ammonia. The films were found to have a (100) planar orientation and a growth rate of 102±5nm/min. Xray diffraction patterns show that the (200) reflection peaks from these GdN films have full widths at half maximum of ca. 1.2°. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source

The sequence dependence of RNA energetics is important for predicting RNA structure. Hairpins with Cn loops are consistently less stable than hairpins with other loops, which suggests the structure of Cn regions could be unusual in the "unfolded" state. For example, previous nuclear magnetic resonance (NMR) evidence suggested that polycytidylic acid forms a left-handed helix. In this study, UV melting experiments show that the hairpin formed by r(5′GGACCCCCGUCC) is less stable than r(5′GGACUUUUGUCC). NMR spectra for single-stranded C4 oligonucleotide, mimicking the unfolded hairpin loop, are consistent with a right-handed A-form-like helix. Comparisons between NMR spectra and molecular dynamics (MD) simulations suggest that recent reparametrizations, parm99χ-YIL and parm99TOR, of the AMBER parm99 force field improve the agreement between structural features for C4 determined by NMR and predicted by MD. Evidently, the force field revisions to parm99 improve the modeling of RNA energetics and therefore structure. © 2013 American Chemical Society. Source

Neutron detection in thick boron carbide(BC)/n-type Si heterojunction diodes shows a threefold increase in efficiency with applied bias and longer time constants. The improved efficiencies resulting from long time constants have been conclusively linked to the much longer charge collection times in the BC layer. Neutron detection signals from both the p-type BC layer and the n-type Si side of the heterojunction diode are observed, with comparable efficiencies. Collectively, these provide strong evidence that the semiconducting BC layer plays an active role in neutron detection, both in neutron capture and in charge generation and collection. © 2010 IOP Publishing Ltd.

Recent studies have established that the highly condensed and transcriptionally silent heterochromatic domains in budding yeast are virtually dynamic structures. The underlying mechanisms for heterochromatin dynamics, however, remain obscure. In this study, we show that histones are dynamically acetylated on H4K12 at telomeric heterochromatin, and this acetylation regulates several of the dynamic telomere properties. Using a de novo heterochromatin formation assay, we surprisingly found that acetylated H4K12 survived the formation of telomeric heterochromatin. Consistently, the histone acetyltransferase complex NuA4 bound to silenced telomeric regions and acetylated H4K12. H4K12 acetylation prevented the over-accumulation of Sir proteins at telomeric heterochromatin and elimination of this acetylation caused defects in multiple telomere-related processes, including transcription, telomere replication, and recombination. Together, these data shed light on a potential histone acetylation mark within telomeric heterochromatin that contributes to telomere plasticity. © 2011 Zhou et al. Source

This study proposes an electrochemical conservation routine applicable to iron archaeological artifacts extracted from their archaeological context and later exposed to a marine atmosphere. The case of study consisted of a Nineteenth Century anchor safeguarded in the Mexican City of Campeche. Metallurgical characterization and electrochemical studies were used to evaluate and assess the conservation process (electrochemical free chloride removal and species reduction, passivation and coating treatment evaluation) and to quantify their effectiveness. Additionally, archaeological information regarding the manufacture process was obtained. The techniques used include potential measurement, potentiodynamic polarization (polarization curves), potentiostatic measurements, electrochemical impedance spectroscopy, electrochemical noise measurements, as well as metallography studies. The method here proposed can then be used in analogous set up as a guideline example for evaluation and assessment purposes during similar procedures. © 2009 Springer Science+Business Media B.V.
