This paper presents a complete methodology for modeling gradings also called non-full-availability groups servicing single-service and multi-service traffic streams. The methodology worked out by the authors makes it possible to determine traffic characteristics of various types of gradings with state-dependent call arrival processes, including a new proposed structure of the Erlang’s Ideal Gra...

Connectivity, or the exchange of individuals among marine populations, is a central topic in marine ecology. For most benthic marine species with complex life cycles, this exchange occurs primarily during the pelagic larval stage. The small size of larvae coupled with the vast and complex fluid environment they occupy hamper our ability to quantify dispersal and connectivity. Evidence from dire...

The impacts of such water transfers are expected to vary temporally and spatially. The aim of this paper is to specify a method to assess these impacts. Although water trading and its impacts have been discussed qualitatively in the literature; there are limited qualitative models available. In the past economists primarily modeled water trading without considering biophysical and systemic cons...

Based on the physico-biophysical considerations, mathematical analysis and some approximate formulations generally adopted in meteorology and ecology, an ecological dynamic model of grassland is developed. The model consists of three interactive variables, i.e. the biomass of living grass, the biomass of wilted grass, and the soil wetness. The major biophysical processes are represented in para...

Many fluorescent proteins are currently available for biological spectroscopy and imaging measurements, allowing a wide range of biochemical and biophysical processes and interactions to be studied at various length scales. However, in applications where a small fluorescence reporter is required or desirable, the choice of fluorophores is rather limited. As such, continued effort has been devot...

INTRODUCTION Treatment of the severe forms of acne vulgaris remains a challenge. Isotretinoin is a drug often used in these cases. Retinoids affect the mechanisms that play a role in the pathogenesis of acne, reduce the production of sebum and sizes of the sebaceous glands. However, isotretinoin appears to have undesirable side effects in the skin, mucous membranes and hair. AIM THE AIM OF TH...

background: the aim of this study was to compare the biophysical profile parameters (bpp), especially amniotic fluid index (afi), before and after administration of corticosteroids (dexamethasone and betamethasone) and these two groups with each other. materials and methods: this double-blind clinical trial study was done on 70 patients for 28–34 weeks women having at least one preterm labor in...
