2Improved performance of UVC-LEDs by combination of high-temperature annealing and epitaxially laterally overgrown AlN/sapphire显示文摘We report on the performance of AlGaN-based deep ultraviolet light-emitting diodes(UV-LEDs)emitting at 265 nm grown on stripe-patterned high-temperature annealed(HTA)epitaxially laterally overgrown(ELO)aluminium nitride(AIN)/sapphire templates.For this purpose,the structural and electro-optical properties of ultraviolet-c light-emitting diodes(UVC-LEDs)on as-grown and on HTA planar AlN/sapphire as well as ELO AlN/sapphire with and without HTA are investigated and compared.Cathodoluminescence measurements reveal dark spot densities of 3.5×10^9 cm^-2,1.1×10^9 cm^-2,1.4×10^9 cm^-2,and 0.9×10^9 cm^-2 in multiple quantum well samples on as-grown planar AIN/sapphire,HTA planar AlN/sapphire,ELO AlN/sapphire,and HTA ELO AlN/sapphire,respectively,and are consistent with the threading dislocation densities determined by transmission electron microscopy(TEM)and high-resolution X-ray diffraction rocking curve.The UVC-LED performance improves with the reduction of the threading dislocation densities(TDDs).The output powers(measured on-wafer in cw operation at 20 mA)of the UV-LEDs emitting at 265 nm were 0.03 mW(planar AlN/sapphire),0.8 mW(planar HTA AlN/sapphire),0.9 mW(ELO AlN/sapphire),and 1.1 mW(HTA ELO AlN/sapphire),respectively.Furthermore,Monte Carlo ray-tracing simulations showed a 15%increase in light-extraction efficiency due to the voids formed in the ELO process.These results demonstrate that HTA ELO AlN/sapphire templates provide a viable approach to increase the efficiency of UV-LEDs,improving both the internal quantum efficiency and the light-extraction efficiency.NORMAN SUSILO EVIATHAR ZIFFER SYLVIA HAGEDORN LEONARDO CANCELLARA CARSTEN NETZEL NEYSHA LOBO PLOCH SHAOJUN WU JENS RASS SEBASTIAN WALDE LUCA SULMONI MARTIN GUTTMANN TIM WERNICKE MARTIN ALBRECHT MARKUS WEYERS MICHAEL KNEISSL 2020Photonics Research2020,8,4:4
3Indirect calorimetry in obese female subjects: Factors influencing the resting metabolic rate显示文摘AIM: To evaluate selected factors influencing resting energy expenditure(REE) in obese female subjects.METHODS: Seventy seven 61 obese Caucasian women [mean age of 52.93 ± 13.45 years, and mean body mass index(BMI) of 41.78 ± 11.54 kg/m2] were enrolled; measurements of resting metabolic rate(RMR) by a ventilated, open-circuit system, indirect calorimeter were performed after an overnight fast. Body composition as well as medications, physical parameters, blood samples, disease pattern, and smoking were considered. RESULTS: RMR was significantly associated with body weight(r = 0.732, P < 0.001), body height(r = 0.401,P = 0.008), BMI(r = 0.504, P < 0.001), waist circumference(r = 0.602, P < 0.001), mid-upper arm circumference(r = 0.417, P = 0.006), mid-upper arm muscle circumference(r = 0.344, P = 0.028), total body water(r = 0.339, P = 0.035), body temperature(r = 0.409, P = 0.007), smoking(P = 0.031), serum T4 levels(r = 0.331, P = 0.036), obstructive sleep apnoea syndrome(OSAS; P = 0.023), impaired glucose tolerance(IGT; P = 0.017) and impaired glycaemic status, including hyperinsulinism, IGT and diabetes mellitus(P = 0.003).CONCLUSION: Future research should be prompted to optimize the procedure of indirect calorimetry to achieve clinical benefits in obese subjects.Theresa Hagedorn Eleonora Poggiogalle Claudia Savina Cecilia Coletti Maddalena Paolini Luciano Scavone Barbara Neri Lorenzo Maria Donini 2012World Journal of Experimental Medicine2012,2,3:2
4德国农业——关于经济、政治及环境可持续性的一些见解显示文摘本文就当前德国农业所发生的主要变化是否与经济、社会、环境和政治可持续性相适应的问题进行了讨论。所讨论的第一个问题是西德农业结构调整的过程和收入问题。结论是农场家庭必须克服的社会困难、由政策变化引起的经济崩溃及农业耕作方式所造成的严重的生态问题明显地不符合可持续发展原则。本文讨论的第二个问题是关于东德农业中发生变化的两个主要方面的转变:集体化农场的重新构建和国有土地的私有化。从长远来看,由这些变化带来的农业的机构配置和组织形式不可能总是可持续的,这是因为转变过程本身带来了巨大的经济转化成本和因其诱发了有关不同利益集团和政治网的寻求各种活动的政治分歧。共同的农业政策(CAP)的现在和末来的变化是本文讨论的第三部分,尤其是关于当前对CAP改革问题的讨论。农业还面临着严峻的可持续的问题。花费在每公顷或每头牲畜的费用使分配产生了巨大的偏差从而降低了经济效益。而这些也只能证明是一些暂时的因价格下降引起的调整过程的补救措施。另外,用于环境项目中改革措施的花费只有很少的一部分。最后,本文通过对一些主要问题的简要说明描述了德国农业的生态状况。Konrad Hagedorn 王燕 1997人类环境杂志1997,26,7:2
