a key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. so, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. the x-ray diffraction patterns indicated that exfoliated ty...
The Fe-Ni-Sb-B amorphous alloy has been prepared by a solid-solid chemical reaction of ferric trichloride, nickel chloride, antimony chloride and potassium borohydride powders at room temperature. The inductive couple plasma study indicates that the resultant is composed of Fe 5.38 %, Ni 56.19 %, Sb 29.02 % and B 0.44 %. The XRD and thermal analysis show that the alloy is a non-strict sense amo...
Gossiping is one of the most crucial applications in Wireless Sensor Networks (WSNs) which has been the focus of many researchers. A main issue of gossiping is how to assign timeslots to nodes for interference-free data transmission. There are three models concerning gossiping in WSNs: unit-sized, bounded-sized, or unbounded-sized messages. For these models, the problem of constructing minimum ...
Background and purpose: In spite of many studies on composting from municipal solid wastes, rural solid wastes have not been studied. A high percentages of rural solid wastes containing domestic, animal and agricultural solid waste is biodegradable. The objective of this research was to study the chemical and microbial quality of compost produced by mixed rural solid wastes and other composts...
In this study, centrifugal casting process was used for producing Al/Mg bimetal. Molten Mg was poured at 700 oC, with 1.5 and 3 melt-to-solid volume ratio (Vm/Vs) into the 450 oC preheated solid Al rotating at 800, 1200, 1600 and 2000 rpm. Castings were kept inside the centrifuged casting machine and cooled down to 150 oC. Investigating the effect of melt-to-solid volume ratio showed that incre...
The aim of the present work was to develop immediate release dosage form of the solid dispersion of glimperide (GLIM) for potential enhancement in the bioavailability. The solid dispersions of GLIM were prepared with PEG6000, PVP K30 and Poloxamer 188, in 1:1, 1:3 and 1:5 %w/w ratio by using solvent wetting and solvent melt method. The in vitro dissolution parameters (%DE10min, %DE30min, %DE60m...
Garcia MLG, Calvo C, Pozo F, et al. Detection of human bocavirus in ill and healthy Spanish children: a 2-year study. This paper has been retracted.
Abstract Hyperspectral imaging has broad applications and impacts in areas including environmental science, weather, geo/space exploration. The intrinsic spectral–spatial structures potential multi-level features different frequency bands make multilayer graph an intuitive model for hyperspectral images (HSI). To study the underlying characteristics of HSI to take advantage signal processing (G...
The alkaline thermal treatment of biomass has recently been proposed as a novel method for producing high purity H2 with suppressed COx formation under moderate reaction conditions (i.e., 523 K and ambient pressure). This technology has a great potential for sustainable bioenergy production because it can handle a wide range of feedstocks including biomass and biogenic wastes with high water co...
