A heterotrophic carbon utilizing microbe (R31) capable of simultaneous nitrification and denitrification (SND) was isolated from wastewater of an Indian slaughterhouse. From an initial COD value of 583.0 mg/L, 95.54% was removed whilst, from a starting NH4 (+)-N concentration of 55.7 mg/L, 95.87% was removed after 48 h contact. The concentrations of the intermediates hydroxylamine, nitrite, and...

Using a repeat sales data set, this paper tests whether a single small seller can influence the selling price of their house. We find that this influence exists and that it dominates the influence of commonly-used market conditions. Since the estimated magnitude of this effect is much higher than expected, we verify the estimate using several supplementary tests. JEL: C78, D80, R21, R31

In this research, which including two cytoplasmic male sterile female (CMS) lines and six recessives branching tester parent (RfRf), 12 hybrids (F 1 ) were obtained by crossing the in Plant Breeding Greenhouse of Field Crops Department 2018-19 winter period. trial was carried out 2019 as four replications. height (cm), head diameter 100 seed weight (g), yield (kg ha -1 ), oil content (%) invest...

In this article, a new type of ruled surfaces in a Lorentz 3-space R31 is obtained by a strictly connected time-like oriented line moving with Frenet s frame along a space-like curve. These surfaces are classified into time-like and space-like surfaces. The wellknown theorems due to Bonnet and Chasles in the 3-dimensional Euclidean space are proved for a time-like ruled surface. 2005 Published ...

School choice systems aspire to delink residential location and school assignments by allowing children apply schools outside of their neighborhood. However, programs also affect incentives live in certain neighborhoods, this feedback may undermine the goals choice. We investigate possibility developing a model public narrows range between highest lowest quality compared neighborhood assignment...
