Transplantation of eelgrass Zostera marina has become a promising restoration tool since natural recolonisation during the last century failed after massive mortality, due to a combination of a wasting disease outbreak and a sequence of human impacts. We studied the interactive effects of planting density and hydrodynamic exposure on the survival of transplants of an annual population of intert...

the seasonal diversity and distribution of microphytes and macrophytes in 40 artificial irrigationponds constructed in a semi-arid region, and the most suitable conditions to maintain these enclaves asbiodiversity spots were studied for the first time. a total of 104 species were detected. bacillariophyta,cyanobacteria and chlorophyta dominated both pelagic and benthic microphytic communities, ...

In this paper we propose a new adaptation technique for improved text-independent speaker verification with limited amounts of training data using Gaussian mixture models (GMMs). The technique, referred to as probabilistic subspace adaptation (PSA), employs a probabilistic subspace description of how a client’s parametric representation (i.e. GMM) is allowed to vary. Our technique is compared t...

Mouse 3T3 cells and their Simian Virus 40-transformed derivatives (3T3SV) were used to assess the relationship of transformation, cell density, and growth control to the cellular distribution of newly synthesized glycosaminoglycan (GAG). Glucosamineand galactosamine-containing G A G were labeled equivalently by [all]glucose regardless of culture type, allowing incorporation into the various G A...

Introduction: Lead is a toxic metal found in the Earth's crust and has been used by humans for 7,000 years due to its high density, flexibility and strength, and low melting point. The widespread use of this metal in industry and the exposure of workers has led to widespread environmental pollution and public health problems in many parts of the world. Due to the widespread use of lead in vario...

Background & objectives: Work-related illnesses account for a large number of social problems. According to occupational therapists, occupational diseases are considered as life-threatening factors for workers. The aim of this study was to measure air pollution to suspended particles and to assess the health risk of PM2.5 and PM10 exposure in the textile industry. Methods: This analytical-cros...

BACKGROUND Children who were only exposed to a mixture of chloromethylisothiazolinone (CMIT) and methylisothiazolinone (MIT) as humidifier disinfectant (HD) components were evaluated for humidifier disinfectant-associated lung injury (HDLI) from 2012. This study was to evaluate the pulmonary function using, impulse oscillometry (IOS) for children exposed to a mixture of CMIT/MIT from HD. METH...
