1用于干形描述的2个少参数削度函数(英文)显示文摘以修正的Brink函数和Pain函数拟合尾巨桉干形曲线。材料来源于南非暖温带花岗岩低地草原地区桉树工业用材林53块标准地的153株尾巨桉干形测定数据。2个削度方程均能对调查数据进行很好地拟合,只是在不同的相对高度时有小的偏差。参数少的方程具有十分好的应用前景,因为从理论上来说,可以用参数预估的方法建立一个广义的干形模型。参数预估不能运用于修正的Brink函数,但在Pain函数的基础上建立参数预估模型是可能的甚至是必要的,因为Pain函数是把绝对树干直径描述为相对树干高度的函数。为此,对参数预估模型是否能描述的树形差异或者仅仅是大小的差异作了测度评价。应用结果表明,参数预估模型未必能用于描述树形的差异。Khalid A.

4Thermoelectric properties of silicon and recycled silicon sawing waste显示文摘Large-scale-applicable thermoelectric materials should be both self-sustaining,in order to survive longterm duty cycles,and nonpolluting.Among all classes of known thermoelectric materials,these criteria reduce the available candidate pool,leaving silicon as one of the remaining options.Here we first review the thermoelectric properties of various silicon-related materials with respect to their morphologies and microstructures.We then report the thermoelectric properties of silicon sawing wastes recycled from silicon wafer manufacturing.We obtain a high power factor of~32 mWcm1 K2 at 1273 K with 6%phosphorus substitution in the Si crystal,a value comparable to that of phosphorus-doped silicongermanium alloys.Our work suggests the large-scale thermoelectric applicability of recycled silicon that would otherwise contribute to the millions of tons of industrial waste produced by the semiconductor industry.Ran He Wieland Heyn Felix Thiel Nicolas Perez Christine Damm Darius Pohl Bernd Rellinghaus Christian Reimann Maximilian Beier Jochen Friedrich Hangtian Zhu Zhifeng Ren Kornelius Nielsch Gabi Schierning 2019Journal of Materiomics2019,5,1:2

6Chronic hepatitis C:Treat or wait? Medical decision making in clinical practice显示文摘AIM:To analyzes the decision whether patients with chronic hepatitis C virus (HCV) infection are treated or not.METHODS:This prospective cohort study included 7658 untreated patients and 6341 patients receiving pegylated interferon α2 a/ribavirin,involving 434 physicians/institutions throughout Germany (377 in private practice and 57 in hospital settings).A structured questionnaire had to be answered prior to the treatment decision,which included demographic data,information about the personal life situation of the patients,anamnesis and symptomatology of hepatitis C,virological data,laboratory data and data on concomitant diseases.A second part of the study analyzes patients treated with pegylated interferon α2a.All questionnaires included reasons against treatment mentioned by the physician.RESULTS:Overall treatment uptake was 45%.By multivariate analysis,genotype 1/4/5/6,HCV-RNA ≤ 520 000 IU/mL,normal alanine aminotransferase (ALT),platelets ≤ 142 500/μL,age > 56 years,female gender,infection length > 12.5 years,concomitant diseases,human immunodeficiency virus co-infection,liver biopsy not performed,care in private practice,asymptomatic disease,and unemployment were factors associated with reduced treatment rate.Treatment and sustained viral response rates in migrants (1/3 of cohort) were higher than in German natives although 1/3 of migrants had language problems.Treatment rate and liver biopsy were higher in clinical settings when compared to private practice and were low when ALT and HCV-RNA were low.CONCLUSION:Some reasons against treatment were medically based whereas others were related to fears,socio-economical problems,and information deficits both on the side of physicians and patients.Claus Niederau Dietrich Hüppe Elmar Zehnter Bernd Mller Renate Heyne Stefan Christensen Rainer Pfaff Arno Theilmeier Ulrich Alshuth Stefan Mauss 2012World Journal of Gastroenterology2012,18,12:2
