BACKGROUND Studies have shown a mixed association between socioeconomic status (SES) and prevalent HIV infection across and within settings in sub-Saharan Africa. In general, the relationship between years of formal education and HIV infection changed from a positive to a negative association with maturity of the HIV epidemic. Our objective was to determine the association between SES and HIV i...

Magnesium (Mg) and its alloys have attached more attention because of their potential as a new type biodegradable metal materials. In this work, AZ31/ZrO 2 nanocomposites with good uniformity were prepared successfully by friction stir processing (FSP). The scanning electron microscope (SEM) transmission (TEM) used to characterize the microstructure composites. mechanical properties, electroche...

OBJECTIVES--To follow up 102 patients with vibration induced white finger (VWF). METHODS--102 subjects with VWF were reexamined one to 13 years after the condition had first been diagnosed. Information about symptoms, occupation, vibration exposure, smoking habits, age, and the prevalence of other diseases was present in the medical records from the first examination and was collected by a ques...

natural plant extracts / products have the potential as safe alternatives for chemical fungicides in plant disease management. methanol and pure methanol: water (50:50 v/v) extracts of peppermint, lavandula, eucalyptus, datura and nettle were screened for their antifungal activity against alternaria sesami, the causal agent of alternaria leaf spot of sesame at 5, 10 and 15% concentrations in sh...

Multipass friction stir processing (MP-FSP) is a solid-state surface modification technique, which was developed based on the simple principle of FSW. Aluminium plates were subjected to MP-FSP from 1 14 passes along longitudinal direction with specified process parameters such as rotational speed 1000 rpm and travel 70 mm/min axial force 15 kN. Subsequently, similar had followed by doublepass (...

The objective of this article is to provide a review of friction stir processing (FSP) technology and its application for microstructure modification of particle reinforced composite materials. The main focus of FSP was on aluminum based alloys and composites. Recently, many researchers have investigated this technology for treating other alloys and materials including stainless steels, magnesi...

BACKGROUND Controlled ovarian stimulation (COH) with intrauterine insemination (IUI) is commonly offered to infertile couples with patent fallopian tubes because it is simple, non-invasive and cost-effective technique. Another non-invasive method is fallopian tube sperm perfusion (FSP). This study was performed to compare the relative efficacy between FSP using fallopian sperm transfer (FAST) s...

Trigonella foenum graecum (fenugreek) is traditionally used to treat disorders such as diabetes, high cholesterol, wounds, inflammation, and gastrointestinal ailments. Recent studies suggest that fenugreek and its active constituents may possess anticarcinogenic potential. We evaluated the preventive efficacy of dietary fenugreek seed and its major steroidal saponin constituent, diosgenin, on a...
