Macro- and micronuclei of Tetrahymena thermophila each contain approximately 30 clusters of 5S genes per haploid genome. Structural changes in DNA sequences associated with some of these clusters occur during the development of the transcriptionally active macronucleus from the transcriptionally inert micronucleus. Exonuclease digestion indicates that DNA fragmentation is not responsible for th...

Obsessive-Compulsive Disorder (OCD) is characterized by absurd, recurrent thoughts (obsessions) followed by certain stereotyped actions (compulsions). 5-Hydroxytryptamine (5-HT) abnormalities may be involved in OCD, and further, cause changes in serotonergic transmission that may have direct or indirect effects on the neuronal firing of other neuromodulators affecting thoughts, feelings and beh...

A novel algorithm for one machine scheduling to minimize total weighted earliness and tardiness using particle swarm optimization is proposed. Existing techniques face challenges such as job size limitations increase in computational time and inaccurate solutions. To overcome these challenges the proposed work implements Meta-Heuristic based particle swarm optimization to optimize the total wei...

We consider the problem of determining the allocation of demand from different customer orders to production batches and the schedule of resulting batches to minimize the total weighted earliness and tardiness penalties in context of batch chemical processing. The problem is formulated as a mixed-integer nonlinear programming model. An iterative heuristic procedure that makes use of the network...

Single machine, distinct due dates, early/lately machine problem and fuzzy environment closely models the situation faced by ‘Just In Time’ manufacturing. The objective of this paper is to sequence the jobs on the machine, so that the total penalty cost be minimum. This cost is composed of the total earliness and the total tardiness cost. An algorithm is developed here to minimize the total pen...

this research in order to identify and introduction of  cotton  suitable cultivar  or cultivars for the double cropping of after wheat and canola harvesting  was carried out in the northern region of ardebil province. in this study, eight  varieties  of    imported cotton germplasm resources in recent years were chosen   and   with the iran's cultivars included  mehr  and varamin  were eva...

OBJECTIVE We hypothesized that early weight gain would be associated with incident obesity, higher blood pressure, systemic inflammation, and arterial wall thickening in later childhood. METHODS A longitudinal birth cohort was recruited antenatally from 2 maternity hospitals in Sydney, Australia, between September 1997 and December 1999. Three hundred ninety-five nondiabetic children who were...
