OBJECTIVE This report presents revised rates of reproduction for 1990-93, reproduction rates for 1994-2002, and intrinsic rates for 2000-2001. The revised rates for 1991-93 are based on populations consistent with the April 1, 2000, census, as are the rates for 1994-2002. METHODS Tabular and graphic data on the reproduction and intrinsic rates by race and Hispanic origin of mother are present...

OBJECTIVE More than half of the pacemaker systems now being implanted can be rate adaptively paced. Our objective was to determine which patients benefit from rate-adaptive pacing in terms of improvement in maximum performance and aerobic capacity. METHODS Thirty patients with implanted accelerometer-driven, rate-adaptive pacemakers underwent a standardized, ergospirometrically and maximally ...

the amount of nitrogen fertilizer is an effective factor on the growth, development, and reproduction of phytophagous insects. to investigate the effect of nitrogen fertilization on intrinsic rate of increase of cabbage aphid, brevicoryne brassicae l., plants rape oilseed (rgs003cultivar) were treated with four nitrogen levels (zero (check) 50, 100, and 150% of recommended levels. the results s...

background: motivation is a driver to health worker performance in most ghanaian hospitals. in view of this, ghana’s ministry of health has rolled out enough motivational policies to accentuate work performance of health workers. objective: the focus of this study was to examine the impact of motivation and identify how intrinsic and extrinsic motivating factors affect the work performance of h...

the seeds of lepidium sativum (garden cress) were selected as a new source of hydrocolloid and some of its fundamental physico-chemical properties such as intrinsic viscosity and functional group were determined. ftir analysis showed that this polymer was composed of carbohydrate with functional carboxyl and hydroxyl groups. intrinsic viscosity was determined to be 1.33 ml/mg in water. the hydr...

self-determination theory (sdt) states that satisfaction of basic psychological needs, including the need for autonomy, competence and relatedness will lead to intrinsic motivation. this study examines the relationship between basic psychological needs and intrinsic motivation of iranian female students in mathematics. for this purpose, 382 students of five school responded to the scale of intr...

sublethal effects of two juvenile hormone analogue, flufenoxuron and lufenuron, were evaluated on larval, pupal and adult stages of habrobracon hebetor say under laboratory conditions. dose-response bioassays were carried out on the insect’s immature and adult stages through dipping and contact residue methods. in the sublethal effect tests, field rates (500 ppm) of the two insecticides were em...
