BACKGROUND The review aimed to compare the effectiveness, safety and acceptability of vasectomy techniques for male sterilization. METHODS We searched five computerized databases and reference lists of relevant articles and book chapters for randomized controlled trials (RCTs) and controlled clinical trials (CCTs) comparing vasectomy techniques. Two reviewers independently extracted data from...

* Department of Soil Science, Punjab Agricultural University, Ludhiana 141 004 Abstract: Different irrigation methods and regimes affect maize (Zea Mays L.) growth differently. The field experiment was conducted to study the interactive effect of three irrigation methods and three irrigation regimes on maize growth under sandy loam soil at the Research Farm of Department of Soil Science, Punjab...

The sustainability of the Hetao Irrigation System, located in the water scarce upper Yellow River basin, is a priority considering the need for water saving, increased water productivity, and higher farmers’ incomes. The upgrading of basin irrigation, the main irrigation method, is essential and includes the adoption of precise land levelling, cut-off management, improved water distribution uni...

crust breaking of saffron is an important operation at the first stage of growth that should be accuratly operated as in this period sprouts of saffron rise up to near the soil surface. after primary irrigation, farmers soften the soil surface by means of different cultivation implements, which enables saffron flowers arise from subsurfarce. this research was conducted to compare tillage implem...

Introduction We aimed to investigate irrigation and drainage characteristics of commercially available urethral catheters and determined which catheter offers the best flow characteristics. Material and methods Twelve different commercially available urethral catheters from three companies (Bard™, Rusch™ and Dover™) were investigated to compare their irrigation and drainage properties. Irriga...

This study was designed to compare the infection rates of simple lacerations irrigated with tap water versus sterile normal saline before repair. Patients with simple lacerations to an extremity that were less than 8 hours from injury were prospectively enrolled. Exclusions from the study were: dog bites, hand lacerations, immunocompromised patients, and those on antibiotics at the time of inju...

PURPOSE To determine whether daily irrigation with sterile saline solution during silicone hydrogel (SiH) contact lens continuous wear (CW) can mitigate increases in corneal epithelial permeability (Pdc) and reduce the risk of adverse events. METHODS In this study, 161 non-contact lens wearers were fit with SiH contact lenses and randomized to either a treatment (n = 81) or control (n = 80) g...

to better understand the potential for improving biomass accumulation and radiation use efficiency (rUE) of winter wheat under deficit irrigation regimes, in 2006–2007 and 2007–2008, an experiment was conducted at the luancheng Experimental Station of Chinese academy of Science to study the effects of deficit irrigation regimes on the photosynthetic active radiation (Par), biomass accumulation,...

The aim of this in vitro study was to determine whether irrigation with apical negative pressure was more effective than traditional positive-pressure irrigation in eradicating Enterococcus faecalis from preshaped root canals. Fifty-four extracted mandibular molars were instrumented to produce either a non-tapered or tapered preparation, sterilized, inoculated with E. faecalis for 30 days, and ...
