Resource selection analyses based on detection data are widely used to parametrize resistance surfaces identify ecological corridors. To successfully resistance, it is crucial decouple resident and disperser behaviours yet date connectivity studies using have not addressed this issue. Here, we decoupled of dispersing wolves by analysing collected within a natural corridor crossing human dominat...

We examine the role of preshearing on flow properties polymer solutions containing essentially an acrylamide-based copolymer obtained from emulsified emulsion inverted by a surfactant. The were presheared using three methods: (1) Buddeberg disperser, (2) Ultra-Turrax and (3) pressure-driven through capillary. Shearing solution was done under fast to induce high stretching chains thus promote br...

phenolic resins have been widely used for selective high technology applications due to their excellent ablative properties, structural integrity and thermal stability that make them appropriate for thermal insulation materials, wood products industry, coatings, moulding compounds and composite materials. polymer layered silicate nanocomposites based on montmorillonite (mmt) have attracted a gr...

A very simple, rapid and sensitive dispersive liquid-liquid microextraction (DLLME) followed by gas chromatography and flame ionization detection (GC-FID) was developed for the determination of phenol and carvacrol in honey samples. A mixture of 100 µl dichloromethane (extraction solvent) and 0.5 ml acetonitrile (disperser solvent) was rapidly injected into sample solution. Thereby a cloudy sol...

Extraction and determination of naproxen from human plasma were performed using Vortex-Assisted Inverted Dispersive Liquid-Liquid MicroExtraction (VA−IDLLME) and High-Performance Liquid Chromatography (HPLC). The parameters affecting extraction recovery such as type and volume of extraction and disperser solvents, pH of sample solution, stirring rate, extraction time and salt addition were ...

water contamination due to the wide variety of pesticides used in agriculture is a global environmental pollution problem. in order to reach at sub-î¼gl-1 levels of detection, an efficient extraction technique is required. a simple, fast and economical method, dispersive liquid-liquid micro extraction (dllme), followed by gas chromatography-mass spectrometry was assessed for determining endosul...
