residual across countries. At a deeper level, we document that the differences in capital accumulation, productivity, and therefore output per worker are driven by differences in institutions and government policies, which we call social infrastructure. We treat social infrastructure as endogenous

proposed approach does not make any assumptions about the presence of infrastructure or about node capabilities, other than the availability of multiple power levels in sensor nodes. We present a protocol, HEED (Hybrid Energy-Efficient Distributed clustering), that periodically selects cluster heads

, where r is the residual vector y − A˜x and t is a positive scalar. We show that if A obeys a uniform uncertainty principle (with unit-normed columns) and if the true parameter vector x is sufficiently sparse (which here roughly guarantees that the model is identifiable), then with very large probability

Background: Pesticides are one of the important sources of environmental pollution that influence human health. The aim of current study was to determine diazinon and benomyl residues levels in mushrooms grown in greenhouses. Methods: Mushroom samples were obtained from 10 active greenhouses

ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression

.7, and 3.3 times more good alignments (“balanced ” score> 0.3) than the next best method (COMPASS), and 1.6, 2.9, and 9.4 times more than PSI-BLAST, at the family, super-family, and fold level. Speed: HHsearch scans a query of 200 residues against 3691 domains in 33s on an AMD64 3GHz PC. This is 10

2.1 Sorting the residue results on a time basis

An efficient modified QuEChERS method combined with high performance liquid chromatography-tandem mass spectrometry detection (HPLC-MS/MS) was established and evaluated for the residue analysis of thifluzamide in rice grain, husk, straw, seedling, paddy water, and soil. Thifluzamide residues were

Concentrations of hexachlorocyclohexane isomers (β,γ,δ HCH), dichlorodiphenyl trichloro ethane (pp, opDDT) and its metabolites ( ppDDE, ppDDD), aldrin, dieldrin, heptachlor, heptachlor epoxide, endosulfan isomers (α, β) and metoxychlor were determined in Benni fish collected from Shadegan, Mahshahr and susangerd cities at Khozestan province in Iran. All the collected fish were contaminated by 14 investigated organochlorine pesticides. The highest and lowest mean concentrations of organochlorine pesticides belonged to β- HCH (65.36 μg/kg) and op DDT (0.13 μg/kg) and were found in Mahshahr and Shadegan Benni fish respectively. Keywords: Organochlorine pesticide, Contamination, Benni fish.

ergy function is designed for fold recognition. It is a residue-level single-body potential so that highly efficient dynamic programming method can be used for alignment optimization. It contains a backbone torsion term, a buried surface term, and a contact-energy term. The energy score combined
