Endocrine and metabolic changes in human aging

Autor: J. E. Morley, W. A. Banks

Publikováno v: AGE. 23:103-115

Numerous alterations in hormonal secretion occur with aging. In general, these tend towards a disintegration of the normal cyclic secretory patterns resulting in lower total circulating levels. In addition, declines in receptors and postreceptor func

Reactions between Cr(VI) and wood and its model compounds

Autor: J. P. de Jesus, W. B. Banks, F. S. Jorge, Teresa M. Santos

Publikováno v: Wood Science and Technology. 33:487-499

Wood, macromolecular and simple model compounds, were reacted with CrO3 or K2CrO4 aqueous solutions. Extracted lignin, guaiacol, vanillin, vanillyl alcohol and homovanillyl alcohol were chosen as model compounds for lignin, whilst cellulose, gum Ghat

Fixation of Chromium in Wood from Trivalent Chromium Salt Solutions

Autor: F. C. Jorge, Teresa M. Santos, J. D. Pedrosa De Jesus, W. B. Banks

Publikováno v: Holzforschung. 53:465-473

Summary The aim of this study was to fix chromium chemically in wood from trivalent chromium solutions. Chromium(III) nitrate, chloride and sulphate salts were applied, both in aqueous and in methanolic solutions. To improve chromium fixation metalli

Extraction and Characterization of Xylose-Rich Pectic Polysaccharide from Wheat Straw

Autor: J. Mark Lawther, W. B. Banks, Run-Cang Sun

Publikováno v: International Journal of Polymer Analysis and Characterization. 4:345-356

Xylose-rich pectic polysaccharide (XRPP) was extracted from defatted and protein-free wheat straw with a pH 1.6 solution adjusted with 20% hydrochloric acid. The yield of XRPP was 1.1% of the dried wheat straw. The isolated XRPP contained 44.8% galac

Isolation and characterization of hemicellulose B and cellulose from pressure refined wheat straw

Autor: J. Mark Lawther, Run-Cang Sun, W. B. Banks

Publikováno v: Industrial Crops and Products. 7:121-128

The hemicellulose and cellulose were extracted with 24% KOH and 2% boric acid at 20°C for 2 h from pressure refined wheat straw holocellulose. The yields were 26.2–28.4% and 41.8–43.0%, respectively. The hemicellulosic material was further fract

Publikováno v: Cellulose. 5:89-111

To aid in the understanding of cellulose ultrastructure, computer modelling has been employed to create a model of monoclinic (Iβ) native cellulose. This was achieved by building a chain of cellulose, which was used in a two chain unit cell. An ener
