Hydraulic conductivities of sands with different gradation and grain shape were estimated experimentally at a relative density (Dr) of about 40 % and a 22 ± 2 °C of constant temperature. Narli Sand (NS) with 0.67 of sphericity (S) and 0.72 of roundness (R), and Crushed Stone Sand (CSS) with 0.55 of S and 0.15 of R values were artificially graded into sixteen different grain-size fractions (4.75...

The carbamate compounds are a class of cholinesterase inhibiting pesticides, and bendiocarb is the most widely used carbamate insecticide used to control disease vectors (mosquitoes, flies, household and agricultural pests). In this study histological structure of rabbit lymphoid tissue and selected parameters of homeostasis after bendiocarb administration were studied. Bendiocarb was perorally...

A multi-platform field measurement campaign involving aircraft and balloons took place over West Africa between 26 July and 25 August 2006, in the frame of the concomitant AMMA Special Observing Period and SCOUT-O3 African tropical activities. Specifically aiming at sampling the upper troposphere and lower stratosphere, the high-altitude research aircraft M55 Geophysica was deployed in Ouagadou...

The spectrum of the compound from V. sativa shows two bands, the more complex one, at higher field, is the AB portion of an ABX spectrum which has been further split by a single proton. The lower field band is the AB part of an ABX spectrum. The position and multiplicities of these bands in the observed spectrum are those expected of the 3and 5-protons of the proposed formula. The 2and 4proton ...

Over 250 British children and adolescents completed a questionnaire on their sources of personal income (pocket money/allowance, part-time job, gifts), as well as how much they had saved, where it was stored, and for what purpose it was intended. Particular attention was paid to bank accounts. The participants also responded to various attitude statements about money and the economic situation ...

Genetic improvement in sows' prolificity is limited by their milk capacities, which do not allow all piglets to survive or grow normally. This experiment compared the behaviour, growth and immune responses of piglets that were weaned early at 6 days of age (EW) vs. control Large White piglets' (C) suckled by their mothers. Behaviour of 9 litters of 5 to 8 piglets in each group were observed fro...

We model entrepreneurship and the emergence of firms as a result of simultaneous bidding for labor services among heterogeneous agents. Unique to our approach is that occupational choices, job matching and organizational forms are determined simultaneously, so that the opportunity costs of entrepreneurs are accounted for. We find that (1) individuals who are relatively unmanageable become entre...

Boron-modified nucleic acids comprise a new set of DNA mimics that have potential biological and therapeutic applications. A series of nine dinucleotides containing N7-cyanoborane-2'-deoxyguanosine ((7b)dG) at the 3', 5' or both positions of the phosphodiester linkage have been synthesized using solution phase phosphoramidite chemistry. Fmoc was used as the 5'-protecting group because of incomp...

In the phototrophic nonsulfur bacterium Rhodobacter capsulatus E1F1, L-alanine dehydrogenase aminating activity functions as an alternative route for ammonia assimilation when glutamine synthetase is inactivated. L-Alanine dehydrogenase deaminating activity participates in the supply of organic carbon to cells growing on L-alanine as the sole carbon source. L-Alanine dehydrogenase is induced in...

The Impact of Teams on Output, Quality and Downtime: An Empirical Analysis Using Individual Panel Data To investigate the size and the timing of the direct impact of participatory arrangements on business performance, we assemble and analyze extraordinary daily data – for rejection, production and downtime rates for all operators in a single plant during a 35 month period, more than 77,000 obse...
