Linear trimetallic Co(III)/Co(II)/Co(III) cobalt complexes with bridging acyl-alkoxy ligands are electrocatalysts for the reduction of tosic acid in acetonitrile. The -OCMe2CH2COMe complex appears to operate homogeneously, and at a modest onset overpotential of 175 mV. A turnover frequency of ca. 80 s(-1) was observed at an overpotential of 300 mV.

We performed spectral line observations of CO J = 2 → 1, CO J = 1 → 0, and CO J = 1 → 0 and polarimetric observations in the λ = 1.3 mm continuum and CO J = 2 → 1 toward a multiple protostar system, L1448 IRS 3, in the Perseus molecular complex at a distance of ∼ 250 pc, using the BIMA array. In the λ = 1.3 mm continuum, two sources (IRS 3A and 3B) were clearly detected with estimated envelope ...

in this study, a total of 101,147 monthly test day records of somatic cell count collected from 13,977 first lactation holstein cows (in 183 herds) calved between 2002 and 2006 were used. for the genetic analysis, a random regression test day model was utilized. somatic cell score (scs) was calculated based on natural logarithm of somatic cell count. in the model, fixed effect of contemporary g...

the glass transition temperature of several pvac(1)-b-poly(ma-co-mma) (2) terpolymers with different fractions of methyl acrylate (ma) and methyl methacrylate (mma) repeating units in random copolymer (block 2) were calculated with barton, kwei and topological equations. the calculation was on the basis of the correlation between the fraction of repeating units in random copolymers and theoreti...

In multiclass semi-supervised learning, sometimes the information about datapoints is present in multiple views. In this paper we propose an optimization based method to tackle semi-supervised learning in the presence of multiple views. Our techniques make use of mixed integer linear programming formulations along with the EM framework to find consistent class assignments given the scores in ea...

Policy, Institutional Factors and Earnings Mobility This paper uses ECHP and OECD data for 14 EU countries to explore the role of labour market factors in explaining cross-national differences in the dynamic structure of earnings: in permanent inequality, transitory inequality and earnings mobility. Based on ECHP, minimum distance estimator is used to decompose earnings inequality into the perm...

نتایج مطالعات مختلف در طول سال های گذشته به خوبی نشان می دهند که با افزایش تولید شیر، عملکرد تولیدمثلی در گاو شیری دچار افت شده است، که این مسأله می تواند سوددهی واحدهای تولیدی گاوشیر را تحت تأثیر قرار دهد به همین دلیل هدف از انجام این مطالعه بررسی صفات تولیدمثلی در شهرکرد بود. در این پژوهش از 700 رکورد مربوط به 501 تلیسه هلشتاین و 1773 رکورد مربوط به788 رکورد رأس گاو (موجود در 8 و 9 واحد پرورش...
