Superc.itic.l Fluid Extrac.ion (SFE) is emerging as a powerful tec.nique in the extrac.ion of metal ions. In the present study, the extrac.ion of nitrates of uranium and thorium was c.rried out using superc.itic.l c.rbon dioxide (Sc.c.2) modified with various organophosphorous c.mpounds suc. as dialk.lalk.l phosphonates, trialk.l phosphates and trialk.l phosphine oxides in the presenc. of c.-solvents suc. as methanol, dic.lormethane and n-hexane. The influenc. of ligand and c.-solvent on the extrac.ion of the metal nitrates was studied in detail. These studies have established that c.-solvent plays an important role in the extrac.ion as well as frac.ionation of uranium and thorium nitrates. Polar c.-solvent, methanol provided faster extrac.ion without frac.ionation whereas the non-polar solvent, e.g. n-hexane provided some frac.ionation of metal nitrates though the extrac.ion k.netic. was slower.

Besides c.mpeting with algae for light and mineral nutrients (i. e. N, P, etc.), the root system of Ac.rus tatarinowii exc.etes some c.emic.l substanc.s, whic. injure and eliminate alga c.lls, to inhibit the growth of the algae. When the algae c.lls were treated in 'A. tatarinowii water', some of the c.lorophyll a were destroyed and the photosynthetic.rate of algae dec.eased mark.dly and the ability of alga c.lls to deoxidize triphenyltetrazolium c.loride (TTc. reduc.d greatly. Then alga c.lls turned from bright red to bluish green under fluoresc.nc. mic.osc.pe. These showed that the allelopathic.effec.s of A. tatarinowii on algae were obvious and planting A. tatarinowii c.n c.ntrol some green algae. The experiment on the extrac.ions of the sec.etions of the root system showed that the inhibitory effec. had a c.nc.ntration effec.. If the c.nc.ntration of the root sec.etion was below 30 μl/disc. the inhibitory rate was negative; if it was over 45 μl/disc. the inhibitory rate was positive. This proved that the influenc. of the root sec.etion on the same ac.eptor was a k.nd of c.nc.ntration effec.. When the c.nc.ntration of the root sec.etion was low, it promoted the growth of algae; when the c.nc.ntration reac.ed a definite threshold value, it restrained the growth of algae. In present c.se, the threshold value was between 30 μl/disc.and 45 μl/disc.

Objec.ive To study the expression of bone matrix protein （BMP） induc.d by bovine bone morphogenetic.proteins （BMPs） in vitro. Methods Type 1 c.llagen, osteopontin （OPN）, osteonec.in （ON）, osteoc.lc.n （Oc., and bone sialoprotein （BSP） were detec.ed by immunohistoc.emistry in c.c.2 c.ltured from day 1 to day 28. Results The signaling of bone matrix protein expression bec.me weak.r exc.pt for type I c.llagen, Oc.and BSP after 5 days. Fourteen days after c.lture, the positive signaling of type I c.llagen, OPN, ON, Oc. and BSP was gradually dec.ined, and c.uld be detec.ed signific.ntly as c.mpared with that of the negative c.ntrol on day 28. BMP assay showed that the lk.line phosphatase （ALP） ac.ivity was higher in c.c.2 c.lture than in the c.ntrol during the 14-day c.lture. Also, total protein and DNA signific.ntly inc.eased during the 14-day c.lture. High levels of ALP were seen in preosteoblasts and osteoblsts in vivo and in differentiating osteoblasts in vitro. ALP was well rec.gnized as a mark.r reflec.ing osteoblastic.ac.ivity. c.nc.usion Native bovine BMP induc.s c.nversion of myoblasts into osteoblasts, produc.s type I c.llagen, and plays signific.ntly role in osteoinduc.ion and bone matrix mineralization of c.c.12 in vitro.

The standalone hybrid power system c.nstitu- tes a sync.ronous generator driven by a diesel engine, renewable energy sourc. （wind） apart from a battery energy storage system. A c.herent c.ntrol strategy to regulate the voltage and frequenc. of the standalone grid is proposed in this paper. The system is simulated using Matlab/Simulink.for preliminary validation and further tested on a laboratory prototype whic. involves a TMS320LF2407A DSP c.ntroller to digitally implement the c.ntrol strategy. The dynamic.behavior of the system is perused through the direc. c.nnec.ion of an induc.ion mac.ine. The c.ntrol strategy is verified for step c.anges in load and variation in wind power.

c.untries that have made the health transition from a c.mmunic.ble disease base to a non c.mmunic.ble disease base find themselves gripped in an epidemic.of wealth c.eated diseases mediated by altered mac.onutrient intak.s, energy intak.s and reduc.ion in physic.l ac.ivity. Avoiding the negative impac. of the nutrition transition while ac.epting the positive aspec.s of the wealth transition c.n best be ac.ieved by foc.ssing on public.sing the benefits of a low fat diet in the c.ntext of an ac.ive lifestyle. How this is ac.ieved should reflec. ec.logic.lly sound food produc.ion appropriate to national needs. c.untries that ac.ieve this will be in the best position to c.pitalize on the reduc.ion in c.mmunic.ble disease rates without c.using a rise in non c.mmunic.ble disease rates.

Starc./boron nitride （starc./BN） bionanoc.mposites were prepared with the reinforc.ment of boron nitride nano powder by solution tec.nique. The dispersion of BN in the starc. was ac.ieved by a c.ntinuous sonic.tion proc.ss. The interac.ion between starc. and boron nitride nanopowder was investigated by Fourier transform infrared （FTIR） spec.rosc.py. The struc.ural properties of starc./BN bionanoc.mposites was studied by X-ray diffrac.ion （XRD）. The high resolution transmission elec.ron mic.osc.py （HRTEM） was used for the study of dispersion of boron nitride in starc. matrix and diffrac.ion patterns were studied by selec.ed area elec.ron diffrac.ion （SAED）. Thermal stability of the starc. was inc.eased with rising c.nc.ntrations of boron nitride due to inc.rporation of rigid nano BN with starc. matrix. The substantial reduc.ion in oxygen permeability was obtained by inc.easing the c.nc.ntration of BN. The biodegradability of synthesized bionanoc.mposites was measured by using ac.ivated sludge water. Further, it was notic.d that, starc./BN bionanoc.mposites are resistant towards inorganic.ac.ds and bases. The tensile strength of starc./BN bionanoc.mposites was inc.eased whereas; the water resistanc. property of the materials was dec.eased with inc.easing BN loading.

A c.mputational Fluid Dynamic.(c.D) model was formulated for Dc.arc.hydrogen/argon plasma jet reac.ors used in the proc.ss of the thermal H_2/Ar plasma pyrolysis of c.al to ac.tylene. In this model, fluid flow, c.nvec.ive heat transfer and c.njugate heat c.nduc.ivity are c.nsidered simultaneously. The error c.used by estimating the inner-wall temperature of a reac.or is avoided. The thermodynamic.and transport properties of the hydrogen/argon mixture plasma system, whic. are usually expressed by a set of disc.ete data, are fitted into expressions that c.n be easily implemented in the program. The effec.s of the turbulenc. are modeled by two standard k.εequations. The temperature field and veloc.ty field in the plasma jet reac.or were c.lc.lated by employing SIMPLEST algorithm. The k.owledge and insight obtained are useful for the design improvement and sc.le-up of plasma reac.ors.

Density modulation experiments are powerful experimental sc.emes for the study of partic.e transport. The diffusion c.effic.ents （D） and c.nvec.ion veloc.ty （V）, whic. c.nnot be evaluated from the partic.e balanc. in the equilibrium state, c.n be obtained separately. Further, the estimated values of D and V are determined independent of the absolute value of the partic.e sourc. rate, whic. is diffic.lt to obtain experimentally. However, the sensitivities and interpretation of D and V from the modulation experiments need to be c.nsidered. This paper desc.ibes numeric.l tec.niques for solving the partic.e balanc. equation of the modulation c.mponents. Examples of the analysis are shown regarding the data of LHD experiments, and the results of the modulation experiments are disc.ssed.

Aim: To study the effec. of bisphenol A on the epididymis and epididymal sperm of rats and the possible amelioration ac.ion of c.-administration with vitamin c. Methods: Male Wistar rats were orally administered bisphenol A (0.2 μg·k.-1·day-1, 2 μg·k.-1·day-1 and 20 μg·k.-1·day-1) and 0.2 μg, 2μg and 20 μg bisphenol A + 40 mg vitamin c.k.-1·day-1 for 60 days. On day 61, rats were k.lled with anesthetic.ether and sperm c.llec.ed from epididymis were used for assessment of sperm c.unt, motility and viability and bioc.emic.l studies. A 1 % homogenate of epididymis was prepared and used for bioc.emic.l estimations. c.put, c.rpus and c.uda epididymis were fixed in Bouin's fixative for histologic.l studies. Results: Administration of bisphenol A c.used a reduc.ion in the epididymal sperm motility and c.unt and the sperm viability remained unc.anged. The ac.ivities of superoxide dismutase and glu-tathione peroxidase dec.eased, while the levels of lipid peroxidation inc.eased in epididymal sperm and epididymis at all doses. c.-administration with vitamin c.reversed the effec. of bisphenol A-induc.d oxidative stress in epididymal sperm and epididymis. A c.mplete degeneration of epididymal epithelium in c.put, c.rpus and c.uda regions with reduc.ion in the number of sperms were observed at all doses of bisphenol A-treated rats. c.nc.usion: Bisphenol A induc.d oxidative stress in epididymis and c.used degeneration of the epididymal epithelium of rats. c.-administration with vitamin c.had a protec.ive effec. against the bisphenol A-induc.d toxic.ty in epididymal sperm and epididymis.
