Abstract:

This study was divided into two main sections; an examination the performance of the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) and attempts to use the imaging spectrometer to estimate foliar biochemical contents over an area of forest. To examine instrument performance the SNR required to estimate foliar biochemical contents from reflectance data was estimated by using laboratory reflectance spectra of vegetation and random noise. A number of methods were used to estimate the SNR of the AVIRIS based on estimates of noise from the instrument and the data. It was concluded that whi

Abstract:

Protein-bound and free lysine contributed to the total lysine content of maize endosperm, and both of these can be significantly increased by the opaque-2 (o2) mutation. Elongation factor 1A is one of the lysine-rich proteins increased in o2 mutants, and its concentration is highly correlated with the protein-bound lysine content of the endosperm. However, the biological basis of this correlation is unknown. The mechanism by which the free amino acid content, including free lysine, is increased by the o2 mutation is also poorly understood. Understanding the biological basis of these traits co

Abstract:

Improvement of feeding regimens for production animals has been hindered by a lack of fundamental knowledge about how the capacity to regulate nutrient absorption across cell membranes affects the function of nutrient metabolizing enzymes. The objective is to determine if the activities and protein content of system X-AG glutamate transporter, its regulatory protein (GTRAP3-18 and ARL6IP1), glutamine synthetase (GS) and glutathione (GSH) content, changes in liver (Experiment 1), longissimus dorsi (LM) and subcutaneous adipose tissue (SF) (Experiment 2) as beef steers transitioned from predomin

A atividade antioxidante (AOX) de vinhos é decorrente, dentre outros fatores, da presença de substâncias fenólicas, como as antocianinas que, além de contribuírem para a formação da cor, devido a sua capacidade redutora, são capazes de neutralizar moléculas de radicais-livres. No presente trabalho, 92 amostras de vinhos tintos da safra 2008/2009, provenientes de diversas regiões do país, agrupadas de acordo com a sua similaridade (UF e fisiografia), foram analisados quanto à cor, através de parâmetros de luz, saturação e tonalidade; à concentração de antocianinas totais (por espectrofotometria

Abstract:

Objective: Biochemical and biomechanical changes occur in the meniscus before osteoarthritis (OA) is clinically diagnosed through symptoms. However, existing techniques to characterize such changes are destructive and time-consuming. This study evaluated the ability of contrast-enhanced computed tomography (CECT) and contrast agent flux using the contrast agents Ioxaglate (ioxaglate) and CA4+ to correlate with the glycosaminoglycan (GAG) distribution and water content in ex vivo human menisci using microCT imaging. Methods: A diffusion-in kinetics study for CA4+ was conducted to determine the

Full text

Abstract:

The relatively high level of palmitic acid (22 mol%) in cottonseeds may be due in part to the activity of a palmitoyl-acyl carrier protein (ACP) thioesterase (PATE). In embryo extracts, PATE activity was highest at the maximum rate of reserve accumulation (oil and protein). The cotton FatB mRNA transcript abundance also peaked during this developmental stage, paralleling the profiles of PATE enzyme activity and seed oil accumulation. A cotton FatB cDNA clone was isolated by screening a cDNA library with a heterologous Arabidopsis FatB probe (Pirtle et al., 1999, Plant and Cell Physiology 40

The objective of this paper is to evaluate the effectiveness of leachate recirculation and bioreactor landfills at enhancing biodegradation, and to optimize the operation of a bioreactor. Waste Management has been examining leachate recirculation landfills for several years. Samples of Municipal Solid Waste (MSW) from existing leachate recirculation (LR) landfills were collected and analyzed for several physical and biochemical properties. These parameters of interest were moisture content, pH, density, temperature, volatile solids, cellulose/lignin ratios, and biological methane potential

Abstract:

<p> Epioblasma capsaeformis, commonly named the oyster mussel, once occupied thousands of miles of stream reaches, but has now been reduced in range to small, isolated populations in a few river reaches. Due to this significant decline in population numbers, a study was conducted to develop a diet for propagating this endangered species under captive conditions. Oyster mussel juveniles were collected from several sites on the Clinch River and sacrificed for gut content and biochemical composition analyses in summer. Feces and pseudofeces from live river-collected juveniles were examined season

Abstract:

Nitrogen availability in agricultural soils from fertilizer, plant residue inputs, and soil organic matter has important implications beyond crop yield. Legume winter cover crops and one fourth the recommended N rate on sweet corn resulted in yields equivalent to those at the recommended rate in the Willamette Valley of western Oregon. Cereal rye winter crops absorbed an average of 40 kg N/ha that otherwise would have been leached, but did not effectively replace fertilizer N. Cereal rye as a cover crop therefore shows an ability to immobilize N from fertilizer. This was further confirmed in a
