Bronchopulmonary dysplasia (BPD) may adversely affect the postnatal growth of the extremely premature infant; however, most studies have not controlled for birth weight. We studied 90 Black premature infants (mean birth weight 989 +/- 148 g). Weight was recorded biweekly until discharge and at 4, 8, and 12 months of age corrected for prematurity. Infants with BPD (N = 23) were contrasted with i...

in order to study the effect of light quality and quantity on morphological and physiological characteristics of two late and early maize (zea maize l.) s.c., an experiment was conducted in greenhouse conditions, ferdowsi university of mashhad, iran, during 2008. the experiment was carried out factorial based on randomized complete block design with six treatments and three replications. differ...

Vital rates and energetics of marine fish larvae were examined in relation to temperature to determine if recruitment potential and spawning strategies might vary as a consequence of differences in these traits among species. Literature-derived values of growth rates, mortality rates. larval stage durations, gross growth efficiencies, and oxygen uptakes were considered. Results were presumed to...

In this study, a soil culture experiment was set up in barrels to investigate the effect of waterlogging duration at different growth stages on the growth, yield, and quality of cotton in the Huang-Huai Region of China during summer. The experiment was conducted at four growth stages of cotton (seedling, squaring, flowering, and boll opening), and the waterlogging duration at each stage was set...

the time of duration of plant developmental stages could have an effect on crop yield and adaptation in a specific environment. the aim of this study was to evaluate the phenological behavior in a wide range of wheat cultivars and their relation with adaptation and potential of crop production in a specific climate (semi-arid and cold). by using a simple lattice design with three replications i...

Many human diseases are characterized by multiple stages of progression. While the typical sequence of disease progression can be identified, there may be large individual variations among patients. Identifying mean stage durations and their variations is critical for statistical hypothesis testing needed to determine if treatment is having a significant effect on the progression, or if a new t...

We consider online learning in repeated decision problems, within the framework of a repeated game against an arbitrary opponent. For repeated matrix games, well known results establish the existence of no-regret strategies; such strategies secure a long-term average payoff that comes close to the maximal payoff that could be obtained, in hindsight, by playing any fixed action against the obser...

The purpose of this study was to investigate the relationship between prolonged stage transition duration (STD) and aspiration. STDs and aspiration ratings were made from videofluoroscopic examinations previously obtained for other studies. Three groups of subjects were examined: (1) 20 stroke patients who aspirated, (2) 31 stroke patients who did not aspirate, and (3) 15 normal subjects. Aspir...
