The integration of gallium nitride(GaN)nanowire light-emitting diodes(nanoLEDs)on flexible substrates offers opportunities for applications beyond rigid solid-state lighting(e.g.,for wearable optoelectronics and bendable inorganic displays).Here,we report on a fast physical transfer route based on femtosecond laser lift-off(fs-LLO)to realize wafer-scale top–down GaN nanoLED arrays on unconventional *** with photolithography and hybrid etching processes,we successfully transferred GaN blue nanoLEDs from a full two-inch sapphire substrate onto a flexible copper(Cu)foil with a high nanowire density(~107 wires/cm2),transfer yield(~99.5%),and *** nanoanalytical measurements were conducted to evaluate the performance and limitations of the fs-LLO technique as well as to gain insights into physical material properties such as strain relaxation and assess the maturity of the transfer *** work could enable the easy recycling of native growth substrates and inspire the development of large-scale hybrid GaN nanowire optoelectronic devices by solely employing standard epitaxial LED wafers(i.e.,customized LED wafers with additional embedded sacrificial materials and a complicated growth process are not required).

本文使用1960-2010年14个碳排放环境库兹涅茨曲线呈现典型倒U型国家的面板数据,采用改进的STIRPAT模型考察了碳排放拐点在能源结构、生产结构、技术水平、贸易结构、消费水平、政策等因素影响下的变化情况。研究发现,碳排放环境库兹涅茨曲线的拐点并未在上述因素的冲击下产生显著变化,该结果证明了经典环境库兹涅茨曲线在拐点预测方面的有效性。在该结论的基础上,本文使用经典环境库兹涅茨模型对中国的碳排放拐点进行了预测,结论表明,在人均GDP增长率为7%的高油价情景下,中国碳排放拐点最早将会在2022年出现。

The Effect of a Food Supplement and a Hair Lotion on the Progression of Androgenetic Alopecia

引用

Journal of Cosmetics, Dermatological Sciences and Applications 2019年第4期9卷 292-304页

作者： Michael Bayer Manfred Gahrtz Werner voss Gerrit Schlippe Thomas Whitfield Dermatest GmbH Münster Germany Oxford Biolabs Deutschland GmbH Regensburg Germany Oxford Biolabs Ltd. Oxford UK

Background: Progressing androgenetic alopecia (AGA), in both sexes, can result in severe distress. Treatments with the capacity to slow down the progression of AGA, or even to bring it to a halt, and at the same time don’t come with side effects are consequently highly sought for. Therefore this study investigates the effect of an over-the-counter nutritional supplement and a similarly formulated topical hair lotion on the progression of AGA. Methods: Seventy-nine healthy study participants of both sexes, who were diagnosed with AGA were divided into 4 study groups. The subjects of the first group were treated with the nutritional supplement, the subjects of the second group with the topical hair lotion, the subjects of the third group with both products, and the subjects of the fourth group served as a no-treatment control. At the beginning and at the end of this nine-month study, the participants were evaluated for their hair loss status. They also answered a questionnaire for self-assessment. A part of the subjects from each study group were further analysed by phototrichography, in order to measure the number of anagen and telogen hairs. Results: It turned out that the supplement, the lotion as well as the treatment with both products not only lead to a reduction in hair loss but also to an increased anagen to telogen hair ratio, whereas no such effects could be measured for the control group. Conclusion: The results show that a systemic delivery via a nutritional supplement, as well as a follicular delivery via a topically applied lotion, both resulted in a reduced hair loss rate as well as in an increased anagen to telogen hair ratio. This demonstrates that the tested formulation is effectively slowing down the progression of AGA.

False contouring effect of the uterine wall during hysteroscopy a lesson from immediate hydrosonography

引用

Open Journal of Obstetrics and Gynecology 2013年第5期3卷 1-4页

作者： Yaron Hamani Ernst voss Asher Shushan Ronit Haimov-Kochman Department of Obstetrics and Gynecology Hadassah Medical Center Mt. Scopus Jerusalem

A 42 years old woman suffering from repeated events of intensive vaginal bleeding during the week off birth control pills was referred for diagnostic hysteroscopy. The patient underwent hysterohy drosonoscopy, a 3-step procedure, including a transvaginal ultrasound scan, a diagnostic hysteroscopy and immediate hydrosonography. A3 cmintramural myoma was detected by the ultrasound scan without impinging onto the uterine cavity as visualized by diagnostic hysteroscopy. However, continuous hydrosonographic evaluation of the uterus, performed immediately afterwards, unveiled a fibroid with a significant intracavitary portion. A falsely normal cavity could be appreciated by high pressured hysteroscopy, while during the gradual fall of the intracavitary pressure a significant lesion could be revealed encroaching into the lumen. In the absence of an agreed distention pressure range during hysteroscopy, an immediate hydrosonography may serve as an auxiliary tool to follow the uterine wall contour as distention pressure declines during the eventual escape of the distention fluid from the lumen. Uterine wall contour is heavily dependent on the distension pressure and guidelines for intrcavitary pressure during hysteroscopy are evidently needed.

Influence of the Degree of Maturation on the Bioactive Compounds in Blackberry (<i>Rubus</i>spp.) cv. Tupy

引用

Food and Nutrition Sciences 2012年第10期3卷 1453-1460页

作者： Josiane K. Rutz Glenise B. voss Rui Carlos Zambiazi Departament of Chemical Engineering and Food Engineering Federal University of Santa Catarina Florianópolis Brazil Department of Agroindustrial Science and Technology Federal University of Pelotas Pelotas Brazil

Fruit consumption is primarily due to the increasing awareness of consumers on the health benefits of a healthy diet. Thus some small fruits stand out because they have bioactive compounds that may have health benefits. Among these fruits is the blackberry, which contains different levels of bioactive compounds depending on the maturation stage. Therefore, the aim of this study was to evaluate the phytochemical and physicochemical compositions of blackberries (cv. Tupy) at three maturation stages. It was observed that during maturation, there was a decrease in acidity, carotenoids and tocopherols and an increase in the total soluble solids, pH, anthocyanins, antioxidant activity and total amount of phenolic compounds. Epicatequin was the major phenolic compound found in blackberries.
