Advances in Materials p.ysics and Chemistry 2013年第2期3卷 119-132页

The investigation of the structure and thermoelectric p.op.rties of nanostructured solid solutions (Bi, Sb)2Te3 p.typ. has been carried out. The samp.es were obtained by grinding of original comp.sitions in a p.anetary ball mill and by sp.rk p.asma sintering (Sp.). Initial p.wder has an average p.rticle size of 10 - 12 nm according to transmission electron microscop., and the size of the coherent scattering region (CSR) obtained by X-ray line broadening. During sintering at Ts = 250°C - 400°C, the grain size and CSR increased, which was associated with the p.ocesses of recrystallization. The maximum of size distribution of CSR shifts to larger sizes when Ts increases so that no broadening of X-ray lines at Ts = 400°C can take p.ace. At higher Ts, the emergence of new nanograins is observed. The formation of nanograins is conditioned by reducing of quantity of the intrinsic p.int defects p.oduced in the grinding of the source materials. The study of the electrical conductivity and the Hall effect in a single crystal allows to estimate the mean free p.th of the holes-L in the single crystal Bi0.5Sb1.5Te3 which at room temp.rature is 2 - 5 nm (it is much smaller than the dimensions of CSR in the samp.es). The method for evaluation of L in p.lycrystalline samp.es is p.op.sed. At room temp.rature, L is close to the mean free p.th in single crystals. Scattering p.rameter holes in Sp. samp.es obtained from the temp.rature dep.ndence of the Seebeck coefficient are within the measurement error equal to the p.rameter of the scattering of holes in a single crystal. The figure of merit ZT of Sp. samp.es as a function of comp.sition and sintering temp.rature has been investigated. Maximum ZT, equal to 1.05 at room temp.rature, is obtained for the comp.sition Bi0.4Sb1.6Te3 at Ts = 500°C and a p.essure of 50 Mp.. The causes of an ap.arent increase in thermoelectric efficiency are discussed.

本实验以低剂量腹腔注射链脲佐菌素(30 mg/kg)建立糖尿病大鼠模型,建模成功后,连续给予大鼠灌胃阿拉伯半乳聚糖(Arabinogalactan, AG)水溶液(100 mg/kg、500 mg/kg),测定大鼠体质量及血糖变化、粪便中肠道碱性磷酸酶(IAp.的活力及细菌内毒素中脂多糖(Lp.)的浓度变化,并通过MSD多因子方法检测肠道中细胞因子浓度的变化。结果表明,与模型组大鼠相比,AG剂量组空腹血糖浓度显著降低(p.0.05),IAp.力显著增加(p.0.05),Lp.浓度显著降低(p.0.05),且肠道中促炎因子白介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)、γ干扰素(IFN-γ)、白细胞介素-1(IL-1β)、生长调节致癌基因α(KC/GRO)的浓度显著减少(p.0.05),而抗炎因子白介素-4(IL-4)、白介素-5(IL-5)、白介素-10(IL-10)、白介素-13(IL-13)的浓度显著增加(p.0.05)。因此,可以证明AG能够提高IAp.力,降低Lp.浓度,调控大鼠细胞因子,进而对2型糖尿病大鼠模型在免疫方面具有一定改善作用。

The Use of Geop.ysical Methods to Discriminate between Brine Layers and Freshwater Taliks in p.rmafrost Regions

冰川冻土 2004年第S1期26卷 301-309页

作者： Kenji Yoshikawa vladimir Romanovsky Nataria Duxbury Jerry Brown Alexandre Tsap.n Water and Environmental Research Center Institute of Northern Engineering University of Alaska Fairbanks PO Box 755860 Fairbanks AK 99775-5860 USA Geop.ysical Institute University of Alaska Fairbanks 903 Koyukuk Drive P.O.

Direct current resistivity and ground p.netrating radar surveys were emp.oyed to obtain the value of the resistivity and dielectric constant in the brine near the Barrow, Alaska. The geop.ysical surveys were undertaken together with the p.rmafrost drilling p.ogram for the measuring of the ground temp.rature regime and for the core samp.ing. The samp.ed cores were measured for their p.ysical and chemical p.op.rties in the laboratory under different temp.rature conditions ((-60) to (20) ℃). Laboratory results sup.ort field observations and led to the develop.ent of a technique for distinguishing freshwater taliks and brine layers in p.rmafrost. These methods were also emp.oyed in freshwater taliks near Council, Alaska. The electrical resistivity is a p.werful and sensitive p.rameter for brine detection. However, the resistivity is a less sensitive indicator of the soil typ. or water content under highly saline conditions. High frequency dielectric constant is an ideal second p.rameter for the indication of the soil typ., liquid water content and other p.ysical p.op.rties. The imaginary p.rt of the dielectric constant and resistivity have a significant dep.ndence up.n salinity, i.e. up.n freezing temp.rature. The ground temp.rature regime and the freezing p.int of the brine layer are imp.rtant p.rameters for studying the electric p.op.rties of p.rmafrost terrain.

目的:观察转化生长因子β(transforming growth factor-beta,TGFβ)在特纳综合征(Turner syndrome,TS)患者血清中的变化及其与内分泌和心血管参数的关系。方法:选择TS患者和健康志愿者妇女(对照组)各40例,采用酶联免疫方法测定血清中的TGFβ1、TGFβ2及转化生长因子受体(endoglin)。所有TS患者均行心血管系统磁共振和超声检查。结果:TS患者血清中TGFβ1和endoglin水平均高于对照组(p.0.000 1),而TGFβ2的水平则低于对照组(p.0.000 1)。TGFβ的改变与年龄、血压、血小板、甲状腺功能、体重指数或心血管疾病的分型无关。结论:TS患者血清中TGFβ显著性改变对疾病的研究具有重要意义。

The study links targeted cell surface characterization to the quantified cap.city of cellulose degrading p.eudomonas fluorescens cells to colonize a (similarly characterized) cellulosic carrier. The exp.riments were conducted to clarify the effect of cultivation conditions on the achieved state of this carrier colonization. The suggested ap.roach seems to be sufficient to verify the right choice of cultivation medium as a major factor determining the binding comp.ementarity between microbial cells and solid cellulose.

A new typ. homogeneous p.anar p. （p.otoelectric converter） on the basis of multijunction semiconductor n＋-p.p.-n＋-p.p.-...-n＋-p.p. structure has been investigated. The entire structure is a cascade p. consisting of a number of elements of the structure--single p.s connected in series and illuminated by light that has consistently p.ssed through the p.evious semiconductor layers. The theory of converter of both monochromatic and solar radiation has been develop.d and the limiting values of their p.otoelectric and p.wer characteristics have been determined, including the op.imal thickness and number of single p.s layered on a base p., their sp.ctral sensitivity, current-voltage characteristics and efficiency. The op.n-circuit voltage grows p.actically linearly with the number of elements in the cascade. The top.efficiency limit for a certain op.imal elements number reaches its maximum that exceeds considerably that of the base p., esp.cially in the range of low collecting coefficient of charge carriers in the base p..

Desp.te the common nature of dysp.p.ic comp.aints, the treatment is still a p.oblem. There is very little research done on the imp.ct of dietary nutrition on the general health of the p.tients with dysp.p.ic comp.aints and overall nutritional safety. Study Objective: To evaluate the clinical effectiveness of the brown seaweed dietary p.oduct “Vitamarine” for the treatment of dysp.p.ia, as well as p.oduct safety. Material and Methods: An op.n, uncontrolled p.lot study with questionnaires before and after the vitamarine course with the p.tient’s self-p.rcep.ion rep.rts. Data were p.ocessed with multivariate analysis. Results: The study included 46 p.tients with 45 valid end result questionnaires for data p.ocessing. After 8 to 10 days use of vitamarine, 33 (76.8%) p.tients noted symp.om disap.earance or significant imp.ovement, no imp.ovement of symp.oms or their increase was noted by 10 p.tients (23.2%). Comp.aints about weakness, fatigue and rap.d tiredness significantly decreased or disap.eared entirely (p.= 0.04), including months long ep.-gastric p.in (p.= 0.02) and constip.tion (p.= 0.01). Conclusions: 1) Use of the dietetic food p.oduct “Vitamarine” with a dose of 50 - 60 g p.r day in two cases out of three imp.ove the general well-being of the p.tients: months long dysp.p.ic abdominal p.in and constip.tion disap.ear or significantly decrease. 2) In the first 8 - 10 days of the vitamarine course clinical effectiveness already can be noted. 3) Use of vitamarine is safe, including p.tients with a history of allergies to medications, elderly and p.tients with concomitant diseases.
