| The paper deals with the formal speciication of a general-purpose multimedia synchronization mechanism, known as the conditional delivery mechanism capable of addressing both intra-and inter-stream synchronization issues. The proposed mechanism, initially introduced in 3, 11], is based on the identiication of causal relations among information units of one or several streams and has the purpo...

Humane culling of embryos before incubation and one-day-old chicks in the first days is most important unsolved problem production poultry products. A number European countries have laws prohibiting destruction male are developing restrictions to limit live avian eggs after 6 incubation. spectral setup for determining sexual dimorphism an embryo a bird egg has been developed based on MV1-D2048x...

there are little information about growth properties of low pathogenic (lp) avian influenza virus (aiv) in embryonated chicken eggs (eces) at different incubation temperatures. knowledge of this information increases the quantity and quality of antigen in vaccine production process. for this purpose, 10-5 dilution of aiv (a/chicken/iran/99/h9n2) was inoculated (intra-allantoic) into 400, 11-day...

The role of alveolar macrophages in the production of granulocyte/ macrophage colony-stimulating factor(s) by the rat lung was investigated. Lavaged lungs, when incubated at proper weight per volume of culture medium, produced the same amount of colony-stimulating factor as unlavaged ones. Both lavaged and unlavaged lungs produced similar types of colony-stimulating factor (s). Prolonged i...

BACKGROUND AND PURPOSE Ischemic stroke lesion volumes have proven difficult to analyze due to the extremely skewed shape of their underlying distribution. We introduce an extension of generalized linear models, beta regression, as a possible method of modeling extremely skewed distributions as evidenced in ischemic stroke lesion volumes. METHODS The NINDS rt-PA clinical trials measured ischem...

A cytomorphometric study was performed in lumbar spinal ganglia neurons of Gallus domesticus on the 10th and 18th incubation days and 8th, 35th, 61st, and 120th post-hatching days. The absolute volume of nucleus and relative volume of cytoplasm were respectively estimated by the Bach caryometric method and by point-counting volumetry, carried out in 0.5 micrometer thick araldite sections. The r...

Biological impacts of climate change are exemplified by shifts in phenology. As the timing of breeding advances, the within-season relationships between timing of breeding and reproductive traits may change and cause long-term changes in the population mean value of reproductive traits. We investigated long-term changes in the timing of breeding and within-season patterns of clutch size, egg vo...

introduction: herogeneous proliferative activity of glioma cells (ie non-cycling cells) is on of the main barriers to the therapeutic of radiolabelled iudr. therefore it is important to evaluate the proliferative heterogeneity on iudr theoretical because theoretical calculation suggests that this could be the dominant factor in the efficacy of treatment. materials and methods: the uptake of iud...
