We, for the first time, demonstrate that orthorhombic V₂O₅ can exhibit superior electrochemical performance in sodium ion batteries when uniformly coated inside nanoporous carbon. The encapsulated V₂O₅ shows a specific capacity as high as 276 mAh/g, while the whole nanocomposite exhibits a capacity of 170 mAh/g. The V₂O₅/C composite was...

Despite the considerable advances of deposition technologies, it remains a significant challenge to form conformal deposition on surface of nanoporous carbons. Here, we introduce a new ambient hydrolysis deposition method that employs and controls pre-adsorbed water vapor on nanoporous carbons to define the deposition of TiO₂. We converted the deposited...

The main objective of the study was an attempt to obtain a
general explanation for the geographical pattern of agricultural income.
This was undertaken in the belief that certain possible determinants
of agricultural income, specifically those related to natural
resource characteristics, have not been satisfactorily considered in
investigations up to...
Selenoprotein W (SeW) is a protein whose function is unknown, but potentially plays a vital role in calcium metabolism, as an indirect link has been established with white muscle disease (WMD). White muscle disease occurs in selenium deficient animals, and is characterized by the precipitation of calcium in muscle, leading...
Dietary cyclopropenoid fatty acids (CPFA) have long
been known to cause pronounced physiological disorders in
both farm and laboratory animals. Past work has shown
CPFA to be a powerful promoter of carcinogenesis in trout,
rats and mice. Sterculic and malvalic acids (CPFA's) are
found in seed lipids of plants from...

Vegetatively propagated peppermint (Mentha piperita L., cv. Black Mitcham) was used to determine the effects of night temperatures (8°C vs 25°C) on the plant growth in terms of fresh weight and leaf area, and on metabolite contents. The plants were sampled after 14 days, 21 days and 28 days in...
The vast area of sandy soils in Thailand which are low in fertility
and can hardly hold water, prompted this investigation. A greenhouse
study was conducted from December 1978 to April 1980 to find out
the effect of straw on nitrogen availability that could affect dry
matter yield and nitrogen...
Na-ion batteries are emerging as one of the most promising energy storage technologies, particularly for grid-level applications. Among anode candidate materials, hard carbon is very attractive due to its high capacity and low cost. However, hard carbon anodes often suffer a low first-cycle Coulombic efficiency and fast capacity fading. In...

Human cathelicidin antimicrobial peptide (CAMP/LL-37) is a cationic antimicrobial peptide that is widely expressed by myeloid and epithelial cells at the human-environment interface. It possesses broad spectrum antimicrobial capacity against bacteria, fungi and viruses. In addition to its direct antimicrobial activity, CAMP/LL-37 also attracts and recruits monocytes, neutrophils and other...
The objective of this study was to further determine the distribution of
selenoprotein W (SeW) in tissues from rats and sheep fed different selenium levels and to
search for the possible functions of this protein. In the rat study a total of 28 rat tissues
were examined and SeW was...
This study was conducted by the School of Forestry at Oregon State University to provide some of the information needed by the Oregon Board of Forestry to develop a forestry program for Oregon. The study makes three contributions: One, a data base that provides an up-to-date timber inventory and information...
Here, we describe and demonstrate a geographic information systems-based lithic morphometric research (GLiMR) software approach. GLiMR accurately and rapidly handles a sequence of ArcGIS procedures to extract geometric morphometric data from 2D and 3D scan files of lithic artifacts. GLiMR generates three main types of geometric properties: shape data, topographic...

A new method for the preparation of the 2, 3, 3a,8a-tetrahydro-2-hydroxyfuro[2, 3-b] benzofuran, XXX, ring system has been developed. The synthesis envolved a substitution reaction of phenol, XXIV, with 1-bromo-2, 5-hexadiene, XXV, to give 2, 5-hexadien-l -yl phenyl ether, XXVII. The ether was rearranged via an ortho-Claisen rearrangement to 3-(o-hydroxyphenyl)-l,...
A hybrid landscape optimization/simulation model called SafeD (Simulation and analysis of forests with episodic Disturbances) was built to address the needs of forest management planning in the Applegate River Watershed, southwestern Oregon (the Apple gate Project). There are two goals of the Applegate Project: 1) search for forest policies and...
Throughout the course of this thesis, I argue that the prose of David Foster Wallace, specifically his posthumously published novel The Pale King, inhabits a middle ground between universal sincerity and the particularized authenticity of postmodern irony. I examine Lionel Trilling's definitions of sincerity and authenticity before moving toward an...
A low-voltage plateau at ∼0.3 V is discovered during the deep sodiation of Na₃V₂(PO₄)₃ by combined computational and experimental studies. This new low-voltage plateau doubles the sodiation capacity of Na₃V₂(PO₄)₃, thus turning it into a promising anode for Na-ion batteries.

Pelargonium graveolens Ait., rose geranium, contains several oxygenated monoterpenes, most of which are related to each other structurally. In this work, the metabolism and interconversions of these terpenes was investigated. A chromatographic analysis of geranium oil was performed initially for the purposes of identifying the terpenes and determining which chromatographic...

Authentic assessment of visitor learning in museum settings is a challenging
endeavor. Evaluation literature includes very few studies that link adult visitors' behavior
to their learning. Multiple data collection methods in a naturalistic environment hold
