Continuous stress–strength interference (SSI) model regards stress and strength as continuous random variables with known probability density function. This, to some extent, results in a limitation of its application. In this paper, stress and strength are treated as discrete random variables, and a discrete SSI model is presented by using the universal generating function (UGF) method. Finally...

iran is widely drought prone, considering its semi-arid climate. eleven wheat cultivars differing in yield potential and drought resistance were employed to determine the possible relationship among grain filling rate and duration, stem reserves remobilization and grain yield under either irrigated (ir) or non-irrigated (nir) conditions at gerizeh research station in sanandaj for a duration of ...

Methods Retrospective study was conducted at WH. This included a total of 1806 women who underwent to C-section from Jan 2008 to Dec 2009. The risk factor data were collected from I.C surveillance notification form of each patient’s SSI. The risk factors which were studied included: age, SSI bundles, type of C-section elective or emergency, duration of operation (less or more than 57 minutes), ...

BACKGROUND Surgical Site Infections (SSI) is the third most commonly reported nosocomial infection which has an adverse impact on the hospital as well as on the patient. A continuous surveillance is called for, to keep a check on the occurrence of SSI. OBJECTIVES to study the incidence of SSI in our hospital.to study the risk factors of SSI in our hospital.to identify the areas in our hospita...

Organic matter is essential in improving the physical, chemical and biological properties of soils. Thus, organic widely considered a crucial indicator environmental quality biodiversity. In this study, effect gyttja addition as soil conditioner on some physical soils formed volcanic serpentine parent materials was investigated. The layout incubation study randomized plots with 3 replications l...

Background Surgical site infections (SSI) are the common nosocomial infection in surgical patients, and are a significant source of postoperative morbidity resulting in increased hospital stay, morbidity and cost. Objective The objective of this study was to obtain the incidence of SSI and determine various risks factors influencing the SSI rate with special reference to the National Nosocomial...

BACKGROUND AND PURPOSE The size variation of single subcortical infarcts (SSIs) may be because of differences in stroke mechanisms or branching patterns of perforators. We aim to investigate this issue using high-resolution MRI. METHODS Patients with high-resolution MRI-identified SSI without significant (≥50%) middle cerebral artery stenosis were enrolled. Perforator stems were defined as pe...
