Application of Granular Activated Carbon (GAC) in adsorption process has been studied for the advanced treatment of municipal and industrial wastewater. Because of entering poisonous compounds such as furfural, phenol and sulfides into the oily wastewater of Tehran refinery, biological aeration basins of wastewater treatment unit may not have the desired performance of COD reductio...

The 1,000 soldiers in this study were consecutive, non-selected cases who were sent to the roentgen (X-ray) department because of a low back complaint. By using their meticulous methodology of measurement, these authors conclude it is possible to accurately measure differences in lower extremity lengths as manifested by a difference in the heights of the femoral heads. The greatest difference i...

Standard morphometric methods were applied to the lungs of 36 boys and 20 girls aged from 6 weeks to 14 years, dying as a result of trauma or after short illnesses. Individual lung units, alveolar dimensions, and number of alveoli per unit area and volume did not differ between boys and girls, but boys had bigger lungs than girls for the same stature. This resulted in a larger total number of a...

BACKGROUND Little other than subjective judgment is available to help clinicians determine when a patient should be transferred out of the intensive care unit. OBJECTIVE To assess whether remaining in the intensive care unit longer than judged to be medically necessary is associated with increased 30-day mortality. METHODS This prospective, observational cohort study was performed in a 13-b...

to study the effect of plant density and planting pattern on iranian ox-tongue, an experiment carried out with two factors: planting pattern (square and rectangular pattern) and plant density (2, 4, 6, 8 plant m-2) in a factorial test performed based on rcbd in 3 replications during 2009-2010 in latmahalleh eshkevarat village in guilan province, iran. characteristics that measured included: dry...

The accurate definition of physiologic normality in man is a prerequisite to quantitation of disease. It has long been known that the total lung volume or a subdivision thereof of a person has limited significance as an isolated measurement unless it can be compared to a normal value. Although the ranges of normality of the various subdivisions, when expressed as a percentage of the normal tota...

the effect of soil and topographic features on distribution of amygdalus scoparia in nehbandan (iran) was investigated. slope, aspect and altitudinal maps were overlaid to prepare a working map unit. quantitative and qualitative traits, including height, number, collar diameter of sprout with the highest diameter, crown diameter and trunk health were recorded in 1000 m2 plots (27 plots). in eac...

OBJECTIVES The purposes of this study were to investigate the use of radial artery applanation tonometry and a generalized transfer function for the assessment of central aortic pressure augmentation in subjects taking commonly used antihypertensive agents (angiotensin-converting enzyme inhibitors, beta-adrenergic blockers, Ca2+ antagonists, diuretic therapy). BACKGROUND Applanation tonometry...

The current empirical study was conducted to investigate the wall neighborhood impact on the two-dimensional flow structure and heat transfer enhancement behind a square cylinder. The low- velocity open-circle wind tunnel was used to carry out the study tests considering the cylinder diameter (D)-based Reynolds number (ReD) of 5130. The selected items to compare were different gap he...
