Abstract In this work, lead(II) adsorption on activated carbons, tire-derived carbon (TAC), and commercial (CAC), in a packed-bed column, was simulated using the Aspen Adsorption® V11 flowsheet simulator. The simulator used to model fixed-bed column establish breakthrough curves by varying initial concentration of ions (500 mg/L, 1000 2000 3000 mg/L), bed height (0.2 m, 0.3 0.4 0.5 0.6 m), flow...

height, weight and body mass index (bmi) of married adults aged 20-69 years with a school-aged child in shiraz (iran) are reported. smoothed centile values have been derived from the raw data by healy's nonparametric method. factors affecting obesity of adults are examined. shiraz adults are taller and heavier than most adults from developing areas of the world, but are shorter and lighter...

This paper provides a simple methodology for the design of air reactor chemical looping combustor to optimize its characteristics when it is employed connected turbo expander produce power. The process, given certain objective (e.g., electric power) defines specifics, namely height and diameter, taking into account following aspects: solids inventory reactor; gas velocity; transport disengaging...

In the present study, we show that the fastest runners and swimmers are becoming not only faster but also heavier, taller and more slender. During the past century, the world record speeds for 100 m-freestyle and 100 m-dash have increased with body mass (M) raised to the power 1/6, in accordance with the constructal scaling of animal locomotion. The world records also show that the speeds have ...

The height of the front of the seat is the primary determinant of appropriate seat size in the school setting. In the present study, this dimension was fixed at 445 mm and, using a brief adjustment period, students adjusted the angle of the seat to their preferred rear seat height (PRSH) under three fixed and one adjustable desk height conditions and for one desk height, under two time conditio...

The physical stature of lowerand upper-class English youth are compared to one another and to their European and North American counterparts. The height gap between the rich and poor was the greatest in England, reaching 22 cm at age 16. The poverty-stricken English children were shorter for their age than any other European or North American group so far discovered, while the English rich were...

Although a height >2SD below the mean for age and gender is used to define short stature, evaluation of short children based on this criteria yields organic etiology only in 14 % of these children. However, when a height SD <−3 is considered for the evaluation of short stature, the proportion of children with organic causes increases to 58 %. Nevertheless, children with height between −2SD and ...
