Groundwater in the Touggourt region—or as its named, Oued Righ—in southeastern Algeria, is only source of irrigation. To assess suitability for agricultural purposes, we collected 72 samples from wells at this region, physical and chemical measurements were carried out each water sample, calculations sodium adsorption ratio (SAR), permeability index (PI), soluble percent (SSP), residual carbona...

abstract turbidity current is one of the most important factors that effect the sediments distribution and also their transportation and release from reservoir. in this study, effects of these currents on sedimentation process in sefidroud dam were simulated by tcm model in 30 years period. comparison between the case of turbidity currents that reach to the dam wall and release from the reservo...

BACKGROUND Lowering the blood cholesterol level may reduce the risk of coronary heart disease. This double-blind study was designed to determine whether the administration of pravastatin to men with hypercholesterolemia and no history of myocardial infarction reduced the combined incidence of nonfatal myocardial infarction and death from coronary heart disease. METHODS We randomly assigned 65...

In the early 1960s the urban area speed limit was increased from 30 to 35 mph in Victoria and NSW. With the introduction of metrication in 1974 the urban area speed limit of 35 mph (56 km/h) was changed to 60 km/h throughout Australia. The reason why 60 km/h was selected is discussed. A study of the likely relationship between travelling speeds and the incidence of pedestrian fatalities was con...

UGF is a small peptide present in the urines and tissues of patients with gynecologic cancers. Published research (which, at present, mainly comes from our laboratory) on the general application of UGF as a tumor marker, and on its use in the diagnosis of ovarian cancer, is reviewed, and new studies on its use, alone and with CA125, in the management of patients with ovarian cancer, are present...

Untreated acetabular dysplasia following treatment for developmental dysplasia of the hip (DDH) leads to early degenerative joint disease. Clinicians must accurately and reliably recognise dysplasia in order to intervene appropriately with secondary acetabular or femoral procedures. This study sought early predictors of residual dysplasia in order to establish empirically-based indications for ...

BACKGROUND AND METHODS Laboratory, clinical, and epidemiologic evidence suggests that calcium may help prevent colorectal adenomas. We conducted a randomized, double-blind trial of the effect of supplementation with calcium carbonate on the recurrence of colorectal adenomas. We randomly assigned 930 subjects (mean age, 61 years; 72 percent men) with a recent history of colorectal adenomas to re...
