Background: The aim of this study was to determine the sperm deformity index (SDI) of proven fertile males and compare this with that of infertile males. Methods: The study was carried out at Islamic International Medical College Rawalpindi and Islamabad Clinic Serving Infertile Couples, Islamabad, from July 2005 to July 2006. It was a cross-sectional comparative study. Fifty healthy fertile ma...

Presumably, hedge fund managers pursue unique strategies, because they possess innovative ideas and superior investment skills, while less skilled managers are more likely to herd and follow publicly known investment strategies. For investors, knowing how innovative and skillful their managers are is thus extremely important but difficult because of the opaque nature of hedge fund operations. I...

As one of the most important technology for implementing large-scale distributed systems, peer-to-peer (P2P) computing has attracted much attention in both research and academia communities, for its advantages such as high availability, high performance, and high flexibility to the dynamics of networks. However, multidimensional data indexing remains as a big challenge to P2P computing, because...

this research was carried out for evaluation of competitive ability of some wheat cultivars (triticum aestivum l.) of recommended wheat in dargaz region with common weed of feral rye (secale cereale). experiment was conducted as factorial based on randomized complete block design with three replications in 2010-2011 growing season. experimental factors were included four wheat cultivars of says...

Traffic resistance of turfgrasses is an essential indicator urban recreational and sports turf quality (TQ). In our study, four turfgrass species were investigated for their wear resistance. A self-made traffic simulator was used to determine the study area in a 2-year field trial (2019–20). The experimental plots established using randomized block design with three replicates. morphological ch...

Abstract This study was intended to analyze dry spell-based drought index (SDI) performance in predicting agricultural drought. Agricultural estimated using soil moisture deficit (SMDI) over a monthly time-scale. The calculated water content profile predicted by SWAT model. result indicated that SDI has poor index. However, the outcome might be explained low temporal resolution of data.

INTRODUCTION Evidence from HIV-negative cohorts suggests a link between osteoporosis and cardiovascular disease. We evaluated the presence and distribution of abdominal aortic calcifications (AAC) and its correlation with bone mineral density (BMD) and vertebral fractures (VF) in a cohort of HIV-positive patients. MATERIALS AND METHODS In this cross-sectional study, 280 asymptomatic HIV-posit...

Pine stand density is a key determinant of damage resulting from attacks by the southern pine beetle (SPB, Dendroctonus frontalis Zimm.). High-density stands of maturing loblolly pine (Pinus taeda L.) are at high risk for losses to SPB, and reducing stand density is the primary tool available to forest managers for preventing and mitigating damage. Field studies are expensive and inflexible for...

Forest attributes and their abundances define the stand structural complexity available as habitat for faunal biodiversity; however, intensive anthropogenic disturbances have the potential to degrade and simplify forest stands. In this paper we develop an index of stand structural complexity and show how anthropogenic disturbances, namely fire, logging, livestock, and their combined presence, a...

Drought is a natural disaster that has impacts on society, the environment, and ecosystem. Ethiopia faced many horrible severe drought events in last few decades. Even though there are some drought-related studies country, most of investigations were focused meteorological analysis. This study was hydrological analysis using streamflow index (SDI). The main objective to identify drought-prone a...
