Th.s study aimed to develop oxide-supported iron-based nanocatalyst and establish.th. particle-size dependence of th. supported iron nanocatalyst in th. Fisch.r-Tropsch.synth.sis (FTS) reaction. Iron nanocatalyst was synth.sized using impregnation meth.d at 3, 6, 10, and 15 wt % on SiO2 and Al2O3-SiO2 supports. Effects of iron loadings and catalyst supports on th. ph.sicoch.mical properties of supported iron nanoparticles were investigated using N2 ph.sical adsorption, temperature-programmed reduction and electron microscopy. Th. performance of th. supported iron nanocatalysts in th. Fisch.r-Tropsch.synth.sis (FTS) was studied in a fixed-bed microreactor at atmosph.ric pressure. Th. average sizes of iron nanoparticles were 5.8 ± 1.2, 8.6 ± 1.1, 12.6 ± 1.3 and 13 ± 1.2 nm for th. 3, 6, 10 and 15 wt% Fe on SiO2, respectively. At lower iron loading (3 and 6 wt %) on SiO2, iron nanoparticles were more uniformly distributed compared to th.se at h.gh.r loadings. Using th. Al2O3-SiO2 support, th. average sizes of iron nanoparticles for th. 3, 6, 10, and 15 wt% Fe were 6.2 ± 1.8, 10 ± 2, 14.5 ± 3.3, and 17.8 ± 5.3 nm, respectively. Th. 3 and 6 wt% Fe/SiO2 resulted in 60% and 54 % CO conversion, respectively at 250oC, h./CO = 1.5 v/v and space velocity, SV=3 L/g-Fe/h. Th. CO conversion decreased to 30% wh.n Fe loading was increased to 15 wt%. Th. CO conversion trend correlated to th. size of th. iron nanoparticles. For 6 wt% Fe/SiO2, th. average size of iron nanoparticles was 8.6 nm wh.reas at 15 wt % iron loading, th. average size of th. iron nanoparticles was 13 nm. As th. size of iron nanoparticles increased from 8.6 nm to 13 nm, th. C5+ selectivity decreased from 20% to 11% wh.reas th. selectivity for th. ligh. h.drocarbons increased from 55 % to 77%.

Catalytic h.drogenation of CO2 into meth.nol and dimeth.l eth.r was carried out over h.brid catalysts consisting of meth.nol-synth.sis catalyst and zeolite. Th. meth.nol-synth.sis catalyst, Cu/ZnO/Al2O3, was prepared by a co-precipitation meth.d. Th.n it was ph.sically mixed with.h.SM-5 zeolite at weigh. ratios of 2：1, 1：1 and 1：2. Th. CO2 h.drogenation reaction was conducted in a fixed-bed microreactor at 250℃ and 40 bar in pre-mixed h./CO2 feed with.h.：CO2 molar ratios of 3：1 and 7：1. Products detected include meth.nol, dimeth.l eth.r, carbon monoxide and water. Conversion of CO2 and yield of oxygenated products were influenced by th. weigh. ratio of Cu/ZnO/Al2O3：h.SM-5 in th. h.brid system and also th. feed ratio. Th. Cu/ZnO/Al2O3： h.SM-5 h.brid at 1：1 resulted in meth.nol yield of 22.0% and was found to be an efficient h.brid catalyst for th. CO2 h.drogenation reaction.

互联网的普及为卫生资源(也称为电子健康)。随着Web 2技术的发展,在线健康社区患者咨询医生在线提供便捷的平台。作为卫生服务涉及患者的生命和死亡,健康越来越受到关注。它是重要的是要了解患者和医生觉得这影响看,影响他们的行为对健康的影响因素。本研究将探讨医生和病人对健康网站的态度,我们的目的是探讨病人选择医生的网上信息的影响,基于他们的态度,健康。医师信息将分为两个维度,包括离线信息和在线信息。此外,本研究将探讨医师对患者的反射行为,根据他们的态度和评价的概念。描述性分析来描述参与的医师。数据用SPSS软件进行统计分析。以及我们使用的实验室检查对患者的态度,医生的信息向电子健康我们用眼动跟踪装置和单因素方差分析对实验结果的影响结果表明,影响医生的个人信息和反馈信息,影响病人的选择态度,反馈信息,具有更大的影响对患者的选择比医生的个人信息。另外的因素很多,包括电子健康的影响的感知利益,自觉关注可能产生的负面影响,评估,阳性患者的经历和社会规范确实影响反射行为的医生与患者讨论类型执行时电子健康。关键词:医生,病人,医生的态度,反映信息,电子医疗,社区卫生本研究将如何看待病人和医师对健康网站的态度。态度影响患者选择医生的医生的个人信息和反馈信息的因素。目前的研究也会看看医生如何与患者的健康互动。它将评估有关健康和他们对患者使用它的行为,医生的态度和信仰之间的关系。更具体地说,它将检查医生的信念,健康,包括感知利益和健康的负面影响,电子健康信息和使用电子医疗病人过去的交互质量,将医师参与调解行为有关。我们用信号理论的概念化和评估医生的离线信息和对患者的在线选择在线反馈信息的影响。信号理论提供了一个合理的解释,对影响信息。本研究将探索医生的态度和行为对健康的影响研究。该理论在解释为什么医生更有可能从事一定的调解行为是有用的。一个横断面在线调查是用于医生收集数据。参与者的问卷调查,通过一个网站。一个在线定制的调查工具是用来创建调查。这个调查花了大约15分钟完成。它包括中介变量的措施,医生的病人相关的互联网使用,电子健康使用感知利益,自觉关注健康的负面影响,医师评估病人健康,体验生成的查询,和积极的经验(医生的感受性和/或电子健康舒适的讨论),此外,本研究采用实验室实验的方法研究了医生的个人信息和反馈对患者选择的态度和个人信息和反馈信息之间的关系强度的影响。本实验采用眼动跟踪机记录下参与者的眼动跟踪和持续关注的信息,我们要确定哪些病人信息关注。确保医生的信息在电脑屏幕的位置不会影响参与者的选择和阅读的时间,地点和医生信息顺序随机出现的参与者,根据左,右,上,下。在这个实验中,医生的信息主要包括两部分内容,个人信息和在线反馈。描述性分析来描述参与的医师。Cronbach.是用来评估测量的可靠性的多个项目的各项措施。采用皮尔森积矩相关系数是用来检查一些假设检验调解行为和几个独立的变量如医生的态度对健康关系的相关分析,过去的基本研究探讨了医生的信息强度,弱或强。我们发现,医生的反馈信息比病人选择医生的个人信息有更大的影响(h.1)。本文的研究不仅证明了在线反馈对患者选择的影响,但我们也发现了医生的信息,在线反馈对患者选择比个人信息较强的冲击强度。这一发现有助于电子健康研究。研究表明,医生确实应该努力参与调解行为和患者健康。本研究确定了几个显著的相关性为正,负的调解,并限制可总结如下。积极调解是通过患者的积极方面,探讨电子健康的代言。结果表明医生可能在病人进行积极协商调解时,他们经常使用电子健康查病人的相关信息(h.A)。医生更倾向于使用积极的调解时,他们认为电子健康有益于患者(h.A)当他们评估健康高度(h.a)。当医生有正面的经验,感觉有建设性的健康进行了讨论,他们也用积极的调解(h.a)。负调解是当医生向患者说明需要使用电子健康因为某些风险要谨慎,如不准确和不完整的健康网站。结果预期显示,医生使用消极调解他们对健康的负面影响的担忧(h.A)。他们还用它当他们额定低评价e-h.alth.h.b)当有一个高频率的病人产生的查询(h.a)。最后,有正面的经验,感觉舒适时,讨论了建设电子健康也更有可能他们会实践负调解(h.B)。限制性调解是医师企图限制位点患者就诊指导他们使用网站的医生同意,告诉他们不要访问其他网站。结果显示限制性调解预期发生时,医生的病人相关的电子用高(h.B)。同时,医生们关注健康的负面影响(h.B)。研究问题2问是否存在一个高频率的医生与病人相关的互联网使用和负调解之间的关系;关系是存在的。以这种方式,电子保健医师使用说明他们有一个整体的积极态度,这意味着他们将有一个积极的态度帮助患者得到尽可能多的优势,对使用电子健康可以。最好的办法是讨论健康的正面和负面的特点的同时,要进一步表明网站的患者应该和不应该访问。研究问题3显示的好处和

Pegylated interferon (PEG-IFN) h.s become standard th.rapy for h.patitis C virus (h.V) infection. We evaluated wh.th.r PEG-IFN ph.rmacodynamics and ph.rmacokinetics account for differences in treatment outcome and wh.th.r th.se parameters migh. be predictors of th.rapeutic outcome. Twenty-four IFN-nave, h.V/h.man immunodeficiency virus-coinfected patients received PEG-IFN α-2b (1.5 μg/kg) once weekly plus daily ribavirin (1,000 or 1,200 mg) for up to 48 weeks. h.V RNA and PEG-IFN αconcentrations were obtained from samples collected frequently after th. first 3 PEG-IFN doses. We modeled h.V kinetics incorporating ph.rmacokinetic and ph.rmacodynamic parameters. Alth.ugh.PEG-IFN concentrations and ph.rmacokinetic parameters were similar in sustained virological responders (SVRs) and nonresponders (NRs), th. PEG-IFN α-2b concentration th.t decreases h.V production by 50%(EC50) was lower in SVRs compared with.NRs (0.04 vs. 0.45 μg/L [P = .014]). Additionally, th. median th.rapeutic quotient (i.e., th. ratio between average PEG-IFN concentration and EC50 [ ˉC/EC50]), and th. PEG-IFN concentration at day 7 divided by EC50 (C(7)/EC50) were significantly increased in SVRs compared with.NRs after th. first (10.1 vs. 1.0 [P = .012], 2.8 vs. 0.3 [P = .007], respectively) and second (14.0 vs. 1.1 [P = .016], 5.4 vs. 0.4 [P = .02], respectively) PEG-IFN doses. All 3 parameters may be used to identify NRs. In conclusion, PEG-IFN concentrations and ph.rmacokinetic parameters do not differ between SVRs and NRs. In contrast, ph.rmacodynamic measurements-namely EC50, th. th.rapeutic quotient, and C(7)/EC50-are different in coinfected SVRs and NRs. Th.se parameters migh. be useful predictors of treatment outcome during th. first month.of th.rapy.

Th.ee different types of Polyeth.lene family, h.gh.Density Polyeth.lene, (h.PE), Low Density polyeth.lene (LDPE) and Linear Low Density polyeth.lene (LLDPE) polymers h.ving different molecular weigh. and density;were pyrolyzed in th. temperature range of 550°C - 1050°C under h., N2 and Ar gases. Taguch. Optimization tech.ique was applied to find out th. best operating conditions to get maximum yield of carbon nano material (CNM). For Taguch. op- timization, experimental set up was done in two different temperature ranges i.e. 550°C - 750°C and 850°C - 1050°C. CNMs synth.sized were ch.racterized by SEM, TEM, Micro Raman and XRD analysis. h.PE was found to yield maximum CNM. Its pyrolysis at 750°C under h.drogen atmosph.re for 2h.gave carbon nano beads and some carbon nano tubes. Wh.reas under same conditions at 1050°C more multi wall carbon nano tubes (MWCNT) were produced, with.some carbon nano beads. XRD data confirmed th. graph.tic nature of carbon-nanotube. Th. intensities of G-band and D-band of Raman spectra suggested th.t CNM h.s more defect sites and spectra were similar for CNM obtained in both.th. temperature ranges. Th. TGA analysis of CNM obtained at 550°C - 750°C, indicated th.t th.y are not amor- ph.us carbon and CNM obtained at 850°C - 1050°C decomposed at 624°C - 668°C;suggesting th.t CNT synth.sized at th.s temperature range were more crystalline th.n wh.t was obtained at th. 550°C - 750°C.
