The bacteriological analyses were Total Plate Count (TPC), Total Coliform Bacteria (TCB), Total fecal Coliform Bacteria (TFCB) and Escherichia coli O157:H7. Bacteriological analysis of tube well drinking water results revealed that highest TPC values 576 cfu/ml and the lowest were 76 cfu/ml, TCB were found in the range 23-<1.1MPN/100ml, TFCB were found in the range 16-<1.1MPN/100ml and E. coli O157:H7 were present in four localities water samples. The Hand pump water samples showed that TPC were in the range 234-32cfu/ml, TCB were found in the range 23-<1.1MPN/100ml, highest TFCB (MPN/100ml) values 16 and lowest values <1.1 and 50% samples were contaminated with E. coli O157:H7. Open well water samples analysis data indicated that 80% samples were unfit due to higher TPC values for human...

Phytochemicals are the natural compound occur in plants, vegetables and fruits, that work with nutrients and fibers to act against diseases or more specifically to act against diseases. As the plants are directly in contact with air, water and soil, the constituents of these sources might contaminate the plants. In addition to the toxic elements such as mercury, arsenic, lead, nickel and cadmium which might be present in some plants and threatened the consumer health, especially the children and elderly. Useful elements such as calcium, magnesium, zinc, manganese and iron are also usually present in plants which help the good health. Many countries have already evaluated their popular herbal medicines with regard to toxic heavy metals. [Naseem Ullah, Muhammad Zahoor, Farhat Ali Khan, Shazeb Khan.

We hypothesized that predictors and outcomes of angiographically impaired culprit vessel flow can be identified and compared. This trial evaluated the outcomes following triage angiography in acute coronary syndromes ineligible for thrombolytic therapy. Eligible patients (n=201) with<24 hours of symptoms were randomized to early triage angiography and subsequent therapies based on the angiogram versus conventional medical therapy. This analysis was performed in 165 patients, from experimental and control arms, in whom angiography was performed on the index hospitalization with the outcome of interest being target vessel flow (Thrombolysis In Myocardial Infarction [TIMI] grades 0 to 2) on initial angiography. Patients with and without impaired culprit lesion flow were similar with respect to ...

The study was conducted using seawater from the Arabian Gulf (higher salinity and temperatures than average seawater). Membranes from several manufacturers were tested under similar operational conditions and the same feed water source. It was found that significant boron rejections, as high as 96%, were successfully achieved, using readily-available commercial RO membranes under a two-pass configuration and without any pH adjustment. Moreover, single-pass configurations exhibited high salt and boron rejection results reaching 99% and 91%, respectively. First pass permeates had boron levels below 1.4 ppm, which are adequate to comply with the new WHO guidelines (2.4 ppm) and those of other countries such as Australia, Canada, and UAE, whose boron guideline thresholds are above 1.4 ppm. The paper also assesses the influence of several operational parameters such as feed water salinity, flow velocity, temperature and feed pressure in second pass on boron removal in this process. It was found that higher boron removals were obtained with higher feed velocity, higher second-pass pressures, and lower feed temperatures.
