Glycinebetaine (betaine) affords osmoprotection in bacteria, plants and animals, and protects cell components against harsh conditions in vitro. This and a compelling body of other evidence have encouraged the engineering of betaine production in plants lacking it. We have installed the metabolic step for oxidation of choline, a ubiquitous substance, to betaine in three diverse species, Arabido...

To establish a baseline understanding of feeding practices on Canadian dairies, survey was distributed online to dairy producers. Responses were split into three categories as follows: western provinces (Alberta, British Columbia, Manitoba, and Saskatchewan; n = 84), Ontario freestall farms (n 75), tiestall 71). Regional differences observed for many feed ingredients; example, corn soybean meal...

Sažetak A study of physico-chemical properties and instrumental measurement of colour and texture was carried out on seven different brands of traditional homemade dry fermented horse salami from Pakrac area. Basic physico-chemical properties, pH values and salt content showed significant variability (p = 0.05), except for the values of aw. Textural and colour parameters (L*, a* and b*) also sh...

Context The rates and pathways of nutrient cycling through ecosystems depend on interactions between both bottom-up forces, including the chemical characteristics of biomass that influence its decomposition and consumption by higher trophic levels, and top-down forces, such as the nutritional requirements andmetabolic efficiencies of consumers and decomposers that influence their feeding and ex...

Abstract Recent excavations at the Pre-Pottery Neolithic A site of Sharara (ca. 9250 cal bc ) in southern Jordan have yielded a rich assemblage charred macrobotanical remains. The bulk this was recovered from single structure settlement that destroyed by fire and which appears to functioned as an area for processing possibly also storing plant foods. Among remains space were nearly 700 fig frui...

Reciprocating compressors of the crosshead design have sealing elements around the piston and piston rod. These seals can be of lubricated or nonlubricated design. This paper will give details about our R&D-work for dry running piston rod sealings or packings for high pressure applications. Starting with an overview of packing design some details are given about tribological tests. Measurements...

in the egg shells when the eggs were studied in UV-light (Fig. 1). Control eggs did not fluoresce. The concentration of oxytetracycline in the egg shell, albumen, and yolk was measured by UV-absorption spectrofluorometry (Hayes and DuBuy, 1964). Oxytetracycline was deposited mainly in the shell (0.182 ± 0.028 iig./gm., mean ± SD), and albumen (0.190 ± 0.030 !*g./gm.) whereas the yolk contained ...

MCC was made from cotton linter using mild acid hydrolysis in 2.5 M solution of HCl at 105° for 1 hour. For the SAXS experiments, MCC powder was immersed in distilled water, ethanol, and acetone about 3 weeks prior to the measurements. Also, dry MCC powder was measured using SAXS to be able to compare the MCC-solvents with the dry state. The previously done wide-angle x-ray scattering (WAXS) st...

Acorns are an important wildlife food resource and seed source for oak regeneration. Most acorn production studies note wide and consistent differences in acorn productivity among individuals, but none clearly demonstrate determinants of productivity. Acorn production by black, northern red, scarlet, chestnut and white oak was measured from 1993 to 1997 in the southern Appalachians was measured...
