Chemical changes in pike perch (Sander lucioperca L Kottelat 1997), rainbow trout (Oncorhynchus mykiss WALBAUM 1792) and eel (Anguilla anguilla L 1766) after hot smoking were investigated. Some differences in water, protein, lipid, ash and carbohydrate contents of the fish were established as significant (P < 0.01). The flesh productivity of fresh eel and pike perch was found to be very high. Differences in group averages of total microprotein content of fresh, smoked and stored eel, rainbow trout and pike perch were found to be significant (P < 0.01). Using polyacrylamide gel electrophoretic analysis, 18 protein bands in rainbow trout, 12 bands in pike perch and 14 bands in eel were determined. Most of the bands disappeared after smoking and storage owing to denaturation of the fish proteins. © 2001 Society of Chemical Industry 相似文献

Adsorption of metal cations by kivircik wool from aqueous NiCl2, CuCl2, ZnCl2, CdCl2, HgCl2 and Pb(NO3)2 solutions at 25°C and 50°C was investigated using atomic absorption spectroscopy. A fiber diffusion controlled adsorption rate model was used to predict the effective diffusion coefficients of metal ions in wool. It has been shown that wool is a potential adsorbent for removing toxic metal ions from contaminated water. 相似文献

Silica gels that were made humidity indicating by impregnation of CoCl2 were used for air drying in isothermal packed column. The effects of type of silica gel, packing height, particle size and air flow rate on breakthrough curves were studied. The breakthrough curves predicted by Rasmuson and Neretniek's analytical solution were in good agreement with experimental data. 相似文献

In order to prevent the emission of SOx, with the flue gas, certain amount of the sulphur of the coal can be retained by adding an adequate amount of lime in the combustion chamber. In this study, two series of experiments were conducted by adding lime at the molar ratios of CaO/S = 0·5 to 2·0 using Ankara-Beypazan lignites, which have around 5 % sulphur content as received form. In one of the series lime was added directly in to the lump coal, and in the other, coal was briquetted together with lime using molasses as binder. It was observed from the experimental results that the increase in the lime ratio leads to an increase in the retained sulphur percentage while it leads to a considerable decrease in thermal efficiency. In order to retain 50 % of sulphur, it was necessary to add lime into lump coal at a CaO/S molar ratio of at least 1,1. This minimum ratio was 0·70 for briquetted coal. When lime was added at these ratios, the thermal efficiencies in the first case dropped to as low as 82 % and to 92 % in the second. 相似文献

The Sideritis species are widely used in the treatment of gastrointestinal disorders, rheumatism, cough, the common cold and as a diuretic, and they are commonly used as an herbal tea in folk medicine in Turkey. The teas of Sideritis have unique tastes, pleasant aromas and a transparent yellow colour, and are preferred as a hot beverage. In order to evaluate this information, the crude methanolic extract and the water soluble part of the methanolic extract after partition with chloroform and n-butanol were investigated for their anti-inflammatory and antinociceptive activities. Phytochemical studies performed on the n-butanol extract of the overground parts of Sideritis brevibracteata, which is rich in phenolic compounds with promising activities, resulted in the isolation of six acetylated allose containing 8-hydroxyflavone glycosides and a phenylethanoid glycoside. The structures of the compounds were established by spectroscopic evidence (UV, IR, NMR, MS). Furthermore, these phenolic compounds of S. brevibracteata were studied for anti-inflammatory, antinociceptive, antioxidant and aldose reductase inhibitory activities. The experimental data demonstrated that S. brevibracteata displayed remarkable anti-inflammatory, antinociceptive and antioxidant activities. 相似文献

A de novo formulation of metformin (MET) was developed through the physical loading of drug into a chitosan-grafted-[poly(acryl amide)-block-poly(acrylic acid)] [CS-g-(PAAm-b-PAA)] terpolymer. For this purpose, CS was functionazed with phthalic anhydride followed by 4-cyano, 4-[(phenylcarbothioyl)sulfanyl]pentanoic acid to produc a macro-RAFT agent (CS-CTA). Afterward, acryl amide and acrylic acid monomers were graft and block copolymerized onto the synthesized CS-CTA through a reversible addition–fragmentation chain transfer (RAFT) polymerization technique to afford CS-g-PAAm copolymer and CS-g-(PAAm-b-PAA) terpolymer, respectively. The fabricated CS-g-(PAAm-b-PAA) terpolymer was loaded with MET as an anti-diabetic drug, and its drug release behavior was evaluated in the body simulated environment. As results, it was concluded that the fabricated CS-g-(PAAm-b-PAA) nanosystem has high potential as de novo drug delivery system (DDS) for diabetes therapy, mainly due to controlled drug release profile in comparison with conventional formulations of MET. © 2019 Wiley Periodicals, Inc.

In this study, a hardware‐accelerated dynamic clustering of moving virtual entities technique is proposed. By clustering virtual entities, both clustered and unclustered virtual agents became more aware of other agents’ topological configurations. Clustering is based on their continuously changing velocity and position vectors. The proposed clustering technique efficiently uses graphics processor's parallel processing capabilities. Therefore, almost no additional central processing unit overhead is required to bring the clustering information into the simulation. In addition, in this paper, how cluster information can be used on top of the proposed virtual human steering technique is explained. The results show that by using the dynamic clustering, the number of collision in the simulation reduces, and the velocities of the the agents in the simulation increase.
