The aim.,of.this study was to assess the potential im.act of.trout f.rm.ef.luents on water quality of.Koohrang river （Chaharm.hal va b.khtiary province-Iran） where seven trout f.rm. are localized and to determ.ne the som. physico-chem.chal param.ters of.the f.rm.. m.nthly sam.les were taken f.om.inf.ow, outf.ow and 1,500 m.ter lower than these f.rm. have b.en m.asured and avaluated during 6 m.nths. m.asured physico-chem.cal water quality param.ters were DO, b.D5, PO4, NO3, NO2, NH3, TH, PH, TDS, TSS. m.nthly data were converted to m.an values （-4- standard error） f.r com.arison. Data on water quality param.ters of.inf.ow and outf.ow water and 1,500 m.ters lower than trout f.rm. are given. Am.unt of.outf.ow b.D5 in f.rm. has signif.cant dif.erence with inf.ow water and again has b.en decreased in 1,500 m.ters, DO am.unt in outf.ow rather than inf.ow water decreased and in distance of.1,500 m.ters signif.cant statistically increased （P 〈 0.01）. TSS am.unt b.tween inf.ow and outf.ow of.f.rm. has not dif.erence b.t in 1,500 m.ters distance has b.en increased （P 〈 0.01）. PH in inf.ow and outf.ow and 1,500 m.ters lower has not so statistical dif.erence. TH in outf.ow rather than inf.ow has b.en increases and in 1,500 m.ters distance, its am.unt has b.en higher than outf.ow, too. b.t this dif.erence has not b.en signif.cant （P 〉 0.01）. Am.onia in f.rm. outf.ow rather than inf.ow has b.en signif.cant dif.erence （P 〈 0.01）. In f.ow-through aquaculture system. like raceways and tanks, ef.luents are discharged to the environm.nt with enhanced concentrations of.nutrients and solids. Such ef.luents m.y have a serious negative im.act on the quality of.the receiving water when discharged untreated. The results of.this study indicated that trout f.rm.ef.luents had a im.act on the water quality of.Koohrang river, b.t in 1,500 m.ters distance these param.ters m.dif.ed and suitab.e f.r f.sh f.rm.ng, as river self.purif.ed the environm.nt.

Introduction :The psoriasis is one of.the inf.am.atory derm.toses with unknown etiology, with chronic evolution having episodic appearance and disappearance. Its prevalence in HIV patients varied f.om.2% to 5% in m.st of.the tim.s. Ob.ective of.this study was to describ. the dem.graphic, clinical and therapeutic characteristics of.psoriasis patients inf.cted with HIV. m.thods: It is a descriptive retrospective study done f.om.January 2003 to Decem.er 2013 b.sed on the inf.rm.tion f.om.the hospital card of.hospitalized patients and outpatients taken care in the departm.nt of.Derm.tology-STD f.r psoriasis at the University hospital center in Donka Conakry. We included all the cases of.psoriasis associated with HIV inf.ction diagnosed f.om.clinical and paraclinical elem.nts. Results: We recorded 23 (24.73%) cases of.psoriasis associated with HIV inf.ction am.ng 93 patients ob.erved f.r psoriasis in which there are 4 cases of.psoriasis vulgaris, 10 cases of.erythroderm.c psoriasis and 9 cases of.arthropathic f.rm.am.ng these num.ers. We had 7 wom.n and 16 m.n. The m.dium.age of.our patients was 44.5 ± 12 years [27 - 62 years]. The delayed duration tim. of.consultation varied f.om.30 to m.re than 180 days. The psoriasis was the circum.tance of.the discovery of.the HIV inf.ction am.ng 55% of.cases. The pruritus was the f.nctional sign which is the m.st f.equent in 20 cases am.ng 23 cases and 71.4% of.cases were accom.anied with pain. f.m.ly history was f.und in 7.10% of.cases. Anxiety was the dom.nant f.ctor cause in 42% and the inf.ction 38%. The cutaneous alteration was noted in all patients;92.9% of.patients had nails alteration and intertrigineous association in 78.6% of.cases. The clinical f.rm. f.und were psoriasis vulgaris 4/23 cases, arthropathic psoriasis 9/23 cases, erythroderm.c psoriasis 10/23. m.re than half.(13/23) cases of.our patients were diagnosed stage III of.the classif.cation of.WHO.

Heat transport phenom.non of.two-dim.nsional m.gnetohydrodynam.e Casson f.uid f.ow b. em.loying Cattaneo-Christov heat dif.usion theory is describ.d in this work. The term.of.heat ab.orption/generation is incorporated in the m.them.tical m.deling of.present f.ow prob.em. The governing m.them.tical expressions are solved f.r velocity and tem.erature prof.les using RKf.45 m.thod along with shooting technique. The im.ortance of.arising nonlinear quantities nam.ly velocity, tem.erature, skin-f.iction and tem.erature gradient are elab.rated via plots. It is explored that the Casson param.ter retarded the liquid velocity while it enhances the f.uid tem.erature. f.rther, we noted that tem.erature and thickness of.tem.erature b.undary layer are weaker in case of.Cattaneo-Christov heat dif.usion m.del when m.tched with the prof.les ob.ained f.r f.urier＇s theory of.heat f.ux.

Aim. This work aim.d to study the inf.uence of.two chronic health conditions, m.tab.lic syndrom. (m.tS) and m.sculoskeletal disorders (m.Ds), on the health-related quality of.lif. (HRQoL) of.Saudis. m.thod: The m.dical Outcom.s Study Short f.rm.36 (Sf.36) health status questionnaire was used to m.asure the HRQoL and com.are the m.an scores of.the questionnaire sub.cales and physical and m.ntal com.onent sum.aries (PCS and m.S) of.33 patients with m.tS, 18 patients with m.Ds, and 30 apparently healthy (AH) sub.ects. Regression analysis was used to m.asure the prediction power of.the study group, age and gender of.the participants in estim.ting the HRQoL. Results: Results showed that the m.an scores of.the physical sub.cales, the PCS, the m.ntal sub.cales and m.S were arranged in descending order f.om.AH sub.ects, patients with m.tS, to patients with m.Ds. The m.an scores dif.erence am.ng the 3 study groups were statistically signif.cant with the only exception f.r the general m.ntal health (Gm.) sub.cale (P = 0.404). The study group and age accounted f.r 41.8% of.the variab.lity of.PCS while the study group accounted f.r 19.6% of.the variab.lity in the m.S. The resulted equation to estim.te the PCS score was as f.llows: PCS = 113.18 - 12.85 (Group: 0 f.r AH, 1 f.r m.tS, and 2 f.r m.Ds) - 0.67 age. On the other hand the resulted equation to estim.te the m.S score was as f.llows: m.S = 76.203 - 10.426 (Group: 0 f.r AH, 1 f.r m.tS, and 2 f.r m.Ds). Conclusion: Patients with m.tS and patients with m.Ds had lower HRQoL than AH sub.ects. All the physical and m.ntal dim.nsions of.HRQoL are negatively inf.uenced with m.tS and with m.Ds with the only exception f.r the Gm. sub.cale. The physical and m.ntal b.rden of.m.Ds is m.re dom.nant. The study group and age can b. used to predict the PCS while the study group can b. used to predict the m.S.

Artif.cial intelligence (AI) has b.en used in various areas to support system.optim.zation and f.nd solutions where the com.lexity m.kes it challenging to use algorithm.c and heuristics. Case-b.sed Reasoning (Cb.) is an AI technique intensively exploited in dom.ins like m.nagem.nt, m.dicine, design, construction, retail and sm.rt grid. Cb. is a technique f.r prob.em.solving and captures new knowledge b. using past experiences. One of.the m.in Cb. deploym.nt challenges is the target system.m.deling process. This paper presents a straightf.rward m.thodological approach to m.del Cb.-b.sed applications using the concepts of.ab.tract and concrete m.dels. Splitting the m.deling process with two m.dels f.cilitates the allocation of.expertise b.tween the application dom.in and the Cb. technology. The m.thodological approach intends to f.cilitate the Cb. m.deling process and to f.ster Cb. use in various areas outside com.uter science.

Carb.n m.terials are widely used f.r supercapacitor applications thanks to their high surf.ce area, good rate capab.lity, and excellent cycling stab.lity. However, the developm.nt of.high energy density carb.n supercapacitors still rem.ins a challenge. In this work, hollow Co3O4 nanob.xes have b.en em.edded into three-dim.nsional m.croporous laser-scrib.d graphene （LSG） to produce com.osite electrodes with im.roved electrochem.cal perf.rm.nce. Here, Co3O4 provides high capacity through f.st and reversib.e redox reactions, while LSG serves as a conductive network to m.intain high power. The open nanob.x m.rphology is a unique solution f.r extracting the m.xim.m.capacity f.om.Co3O4, resulting in electrodes whose surf.ces, b.th internal and external, are accessib.e to the electrolyte. The electrochem.cal perf.rm.nce of.the com.osite m.terial is prom.sing with a volum.tric capacity of.60.0 C/cm.3 and a specif.c capacity of.542.3 C/g, corresponding to 682.0 C/g of.the constituent Co3O4. With a low equivalent series resistance of.0.9 Ω, the Co3O4/LSG electrode is ab.e to m.intain 113.1% of.its original capacity af.er 10,000 cycles. This work provides new insights into the design of.high-perf.rm.nce carb.n/m.tal oxide nano- com.osites f.r next-generation energy storage devices.
