Efficient processing, handling, and storage of corn stover, a major crop‐based biomass, require an understanding of the moisture sorption thermodynamic properties of its fractions. Moisture sorption thermodynamic properties of the major corn stover fractions such as leaf, stalk skin, and stalk pith were determined, utilizing the static gravimetric sorption isotherms data in the temperature rang...

Although qualitative inquiry has developed into a popularized and very useful way of conducting research within the health sciences, there has been a relatively disproportionate amount of literature devoted to “who“ is represented in such inquiries. It is most often assumed that the end text should present an objective, value-free, and accurate representation of the participants and therefore e...

The major aim of this study was to compare the morphology and activity of rumen protozoa of Khuzestan water buffalo and Holstein cow using in vitro digestibility and gas production parameters of steam treated sugarcane pith. Rumen fluid obtained from two buffalo and cow steers fed the same diet, 30:70 concentrate: forage. To separate rumen protozoa, antibiotic solution and fungicides were added...

The influence of ethylene on growth in etiolated lupine (Lupinus albus L.) hypocotyls was studied in ethephon-treated plants. Ethephon reduced the length and increased the diameter of hypocotyls. At the end of the hypocotyl growth period (14 days), the fresh weight was reduced by 53%, and the dry weight was reduced by 16%. Thus, ethylene reduced water uptake in the tissues to a greater extent t...

PALAVRAS-CHAVE Densidade Sentido medula-casca sentido base-topo ABSTRACT: The wood density is one of the parameters that most affect its properties, which makes it knowledge essential for any use indication. However, due to the high variability of this aspect within the tree, its determination shall consider a sampling throughout the stem. Thus, this study aimed to evaluate the longitudinal and...

Position-resolved small-angle X-ray scattering was used to investigate the nanostructure of the wood cell wall in two softwood species (Norwegian spruce and Scots pine) and two hardwood species (pedunculate oak and copper beech). The tilt angle of the cellulose fibrils in the wood cell wall versus the longitudinal cell axis (microfibril angle) was systematically studied over a wide range of ann...

Three auxin analogs, 4-, 5-, and 6-azido-3-indoleacetic acid (4-N(3)-IAA, 5-N(3)-IAA, and 6-N(3)-IAA) have been synthesized for use as fluorescent photoaffinity labeling agents. The pK(a) values of these compounds (4-N(3)-IAA, 4.67; 5-N(3)-IAA, 4.65; 6-N(3)-IAA, 4.66; all +/- 0.04) are experimentally indistinguishable from the pK(a) of 3-indoleacetic acid (IAA, 4.69 +/- 0.04). The auxin activit...

Increasing global concern over the environmental issues and depletion of fossil fuels, significant interest has been shown by the researchers to develop alternate energy technologies like biomass, biogas, solar to meet the future energy demand. The prediction of the performance of different biomass energy sources in gasifiers is needed for the implementation of this technology to fulfil the nee...

European and Mediterranean corn borers are two of the most economically important insect pests of maize (Zea mays L.) in North America and southern Europe, respectively. Cell wall structure and composition were evaluated in pith and rind tissues of resistant and susceptible inbred lines as possible corn borer resistance traits. Composition of cell wall polysaccharides, lignin concentration and ...
