glycerol is a promising feedstock for microbial cultivation and production of 1,3 propanediol (1,3 pdo). here we report a newly isolated bacterial strain ba11 from soil, capable of fermenting glycerol to 1,3 pdo, and has been identified to be a strain of klebsiella pneumoniae. strain ba11 was fast growing showing peak 1,3 pdo production in 6 h of cultivation with productivity of 1.2 g/l-h witho...

in this study, the mineralogical composition and concentration of heavy metals in surfacesediment of north west persian gulf (musa estuary and hendijan coastline) were investigated. fifteensampling sites were selected and the sediment samples were collected using peterson grab sampler in august2013. xrd analyses demonstrated that the sediments of study area are principally composed of calcite,q...

Environmental enrichment is a critical component of Refinement, one of the 3Rs underlying humane experimentation on animals. In this paper I discuss why primates housed in laboratories, which often have constraints of space and study protocols, are a special case for enrichment. I outline a framework for categorising the different types of enrichment, using the marmoset as a case study, and sum...

The enrichment of the Intra-Cluster Medium (ICM) with heavy elements is reviewed. There is now good observational evidence for enrichment including abundance ratios and metallicity distributions. Various processes involved in the enrichment process – rampressure stripping, galactic winds, galaxy-galaxy interactions, AGN outflows and intra-cluster supernovae – are described. Simulations of the I...

Although environmental enrichment improves spatial memory and alters synaptic plasticity in aged rodents, it is unclear whether all types of enrichment treatments yield similar benefits. The present study examined the effects in aged male mice of three types of enrichment on spatial memory in Morris water maze and radial arm maze tasks, and on levels of the presynaptic protein synaptophysin in ...

The role of enrichment culture for the isolation of Campylobacter jejuni from faeces is discussed. It is concluded that enrichment culture is only necessary for those specimens where it is anticipated that the number of organisms is likely to be low. In a trial of a blood free enrichment broth (CCD broth) and the modified Preston enrichment broth the latter gave significantly superior results.

This paper is concerned with automatic enrichment in the particlepartition of unity method (PPUM). The goal of our automatic enrichment is to recover the optimal convergence rate of the uniform h-version independent of the regularity of the solution. Hence, we employ enrichment not only for modeling purposes but rather to improve the approximation properties of the numerical scheme. To this end...

Proliferation of data sources associated to Internet Things (IoT) deployment as well those bound Open Data Portals (e.g. European Portal, Municipalities Portals, etc.) and Social Media platforms is creating an abundance information that called bring benefits for both the private public sectors, through development added-value services, increasing administrations’ transparency availability or fo...
