Spontaneous imbibition happens in many natural and chemical engineering processes in which the mean advancing front usually follows Lucas-Washburn's law. However it has been found that the scaling law does not apply in many cases. There have been few criteria to determine under what conditions the Washburn law works. The effect of gravity on spontaneous imbibition in porous media was investigat...

The monomeric model of rhodopsin-like G protein-coupled receptors (GPCRs) has progressively yielded the floor to the concept of GPCRs being oligo(di)mers, but the functional correlates of dimerization remain unclear. In this report, dimers of glycoprotein hormone receptors were demonstrated in living cells, with a combination of biophysical (bioluminescence resonance energy transfer and homogen...

The present study was carried out in a field located at Department of Botany, University of Karachi where soil was treated with various concentrations of pesticides before sowing. Combined effects of pesticides on soybean growth and nutritive composition of seeds were observed. Pesticide treated soil had significant effects on leaf growth components such as leaf area ratio, leaf area index, spe...

We used a computer-based method to help validate the reference ranges of assays for triiodothyronine (T3) and thyroxin (T4). A retrospective search of a database of laboratory results for the previous six months identified all patients with apparent euthyroid status, as defined by methods independent of the immunoassay under review. A computer-generated reference group (CGR Group) of 2001 recor...

Residual renal function (RRF) is a key element for good maintenance of patients on peritoneal dialysis (PD). Several reports have been published comparing RRF preservation between continuous ambulatory PD and automated PD (APD); however, no comparisons have yet been made between tidal and non tidal APD. We therefore retrospectively analyzed RRF in patients on tidal (n = 10) and non tidal (n = 1...

Field experiments were conducted to evaluate plant population and N-fertilizer effects on yield and yield components of maize (Zea mays L.). Three levels of plant populations (53000, 66000, and 800,000 plants ha⁻¹ corresponding to spacings of 75 × 25, 60 × 25, and 50 × 25 cm) and 4 doses of N (100, 140, 180, and 220 kg ha⁻¹) were the treatment variables. Results revealed that plant growth, ligh...

In several species including the buffalo cow, prostaglandin (PG) F2α is the key molecule responsible for regression of corpus luteum (CL). Experiments were carried out to characterize gene expression changes in the CL tissue at various time points after administration of luteolytic dose of PGF2α in buffalo cows. Circulating progesterone levels decreased within 1 h of PGF2α treatment and evidenc...

Article history: Received 17 May 2013 Received in revised form 27 May 2013 Accepted 30 May 2013 Available online 10 June 2013 This paper provides comprehensive, detailed documentation of major corporate governance reforms (CGRs) undertaken by 26 advanced and emerging economies. We investigate whether these reforms have altered investor protection (IP) and impacted corporate investments. Specifi...

Space information networks (SINs) are pushing the boundaries of networking into near-Earth orbit and beyond. Nevertheless, harsh costly space context forces most risk-prone missions to be designed with minimal chance failure. The careful consideration routing protocols used connect fleet is by no means exception. Although decentralized SIN schemes have received attention research community, cen...
