-Illite polytype quantification allows the differentiation of diagenetic and detrital illite components. In Paleozoic shales from the Illinois Basin, we observe 3 polytypes: 1M d, 1M and 2M~. 1M d and 1M are of diagenetic origin and 2M1 is of detrital origin. In this paper, we compare experimental X-ray diffraction (XRD) traces with traces calculated using WILDFIRE 9 and quantify mixtures of al...

Simulations of 29Si and 23Na MAS NMR spectra indicate the presence of differing proportions of two polytypes and a third phase in three samples of penkvilksite, Na4Ti2Si8O22•5H2O. The most abundant peaks are assigned to the 2O and 1M polytypes, and a third set of peaks are provisionally assigned to a proposed 2M polytype. The quadrupolar interaction parameters for 23Na, Cq and , were calculated...

Bacillus subtilis bacteriophage phi 1m, a host-range variant, was isolated after mutagenesis of virulent bacteriophage phi 1. Unlike its wild-type antecedent, phi 1m could not form plaques on lawns of B subtilis 168 at 37 C, although it adsorbed to, penetrated, and killed this bacterium. Experiments conducted in liquid medium at 37 C showed that B. subtilis 168 cells allowed reduced levels of p...

A near-diploid mouse fibroblast cell line m5S/1M used in this study shows a high sensitivity to contact-dependent inhibition of growth, and the addition of EGF causes both morphological change and loss of contact-dependent inhibition of growth. The m5S/1M cell and its transformants obtained by x-ray irradiation have been used to search for the cell surface glycoproteins that are responsible for...

The objective of this study was to evaluate the physical and chemical properties of the broiler feather concentrate (BFC) in different hydrolysis processes. The raw materials in the form of broiler feather waste (BFW) were hydrolyzed into broiler feather concentrate (BFC) products in the form of feather meal. A total of 1000 g of dry feather samples were used in this study. The study was design...

On-farm production of protein is limited in most dairy farm operations in arid and semi-arid environments. Cereal-legume intercropping could be a viable option to obtain forage with higher protein content. A two-year experiment was conducted during 2009 and 2010 growing seasons in a loamy soil to determine whether intercropping pattern of barley (Hordeum vulgare L.) and annual medic (Medica...
