Classification of edge‐transitive rose window graphs

Given natural numbers n?3 and 1?a, r?n?1, the rose window graph R_n(a, r) is a quartic graph with vertex set $\{{{x}}_{{i}}|{{i}}\in {\mathbb{Z}}_{{n}}\} \cup \{{{y}}_{{i}}|{{i}}\in{\mathbb{Z}}_{{n}}\}Given natural numbers n?3 and 1?a, r?n?1, the rose window graph R_n(a, r) is a quartic graph with vertex set $\{{{x}}_{{i}}|{{i}}\in {\mathbb{Z}}_{{n}}\} \cup \{{{y}}_{{i}}|{{i}}\in{\mathbb{Z}}_{{n}}\}$ and edge set $\{\{{{x}}_{{i}},{{x}}_{{{i+1}}}\} \mid {{i}}\in {\mathbb{Z}}_n \} \cup \{\{{{y}}_{{{i}}},{{y}}_{{{i+r}}}\}\mid {{i}} \in{\mathbb{Z}}_{{n}}\}\cup \{\{{{x}}_{{{i}}},{{y}}_{{{i}}}\} \mid {{i}}\in {\mathbb{Z}}_{{{n}}}\}\cup \{\{{{x}}_{{{i+a}}},{{y}}_{{{i}}}\} \mid{{i}} \in {\mathbb{Z}}_{{{n}}}\}$.

青春期体质指数及腰臀比的性别差异

目的 探讨青春期体质指数(BMI)及腰臀比(WHR)的性别差异。方法 整群抽取广州市六年级及高三学生1 309名,按内科常规进行BMI、腰围、臀围等检查,通过科学统计,分析青春期体质指数(BMI)及腰臀比(WHR)的性别差异。结果 在青春期各年龄段中,BMI、WHR均具有显著性差异,男生的BMI、WHR均显著大于女生;在相关性分析中,我们发现青春期WHR与性别的相关性比BMI与性别的相关性更为密切。结论 我市青春期学生中男性的超质量或肥胖现象比女生更为显著,而BMI更适合于评价整体学生体格发育情况。     

Determination of Chemical Composition of Commercial Rose Bengal Preparations by Chemical and Biological Methods

The method of the fraction separation in commercial rose bengal has been described. Individual fractions were identified on the basis of the absorption maxima obtained on a spectrophotometer. Iodine labelled rose bengal was used for biological investigation in the experimental animals. It was found that rose bengal produced by Durand contains a high percentage of the main component of tetraiodotetrachlor-fluoresceine (absorption maxima at 548 nm) and is therefore most suitable for the labelling process.     

Effect of bengal rose sensitizer on activity of the photosynthetic apparatus of green barley leaves

We have observed disruption of the energy distribution between chlorophyll-protein complexes, their partial degradation, and inactivation of photosystem II in green barley leaves under photooxidative stress conditions induced by the photosensitizer bengal rose. __________ Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 73, No. 2, pp. 266–269, March–April, 2006.

Long-term stability of emulsion based on rose oil

This paper was aimed at determining the parameters responsible for the long-term stability of emulsions. Compositions of six emulsions with different amounts of emulsifier and thickener were developed according to the authors’ own specifications and requirements of KT-Skor software (based on Kleeman’s method). Physical properties of the emulsions were evaluated (determination of emulsion type, structure of emulsion, stability tests, viscosity, average particle size, and dispersity index). The results obtained indicate that the emulsion containing 10?g of rose oil and 0.2?g of thickener exhibited the highest stability.     

Über die Bindung von Jodid an mit Silberchlorid präparierte Keramikkörper

Mit Radiojod markierte Präparate haben eine erhebliche Bedeutung in der klinischen Diagnostik. Besonders die mit ¹³¹J markierten Verbindungen unterliegen jedoch während ihrer Lagerung einer erheblichen Autoradiolyse infolge der in der Substanz absorbierten Strahlungscenergie.     

Blood flow and arterial endothelial dysfunction: Mechanisms and implications

The arterial endothelium exquisitely regulates vascular function, and endothelial dysfunction plays a critical role in the development of atherosclerosis. Atherosclerotic lesions develop preferentially at arterial branches and bifurcations where the blood flow is disturbed. Understanding the basis for this observation requires elucidating the effects of blood flow on the endothelial cell (EC) function. The goal of this review is: (1) to describe our current understanding of the relationships between arterial blood flow and atherosclerosis, (2) to present the wide array of flow-induced biological responses in ECs, and (3) to discuss the mechanisms by which ECs sense, transmit, and transduce flow-derived mechanical forces. We conclude by presenting some future perspectives in the highly interdisciplinary field of EC mechanotransduction.     

局部氧疗配合炉甘石治疗新生儿红臀的临床观察

为探讨氧气疗法对新生儿臀红的治疗效果,将2000年1月—2004年12月100例臀红患儿随机分为观察组和对照组。两组新生儿臀部均涂用炉甘石洗剂,观察组患儿在涂用炉甘石之前予氧气疗法;对照组不给予氧气,观察两组治疗痊愈天数。结果表明,观察组与对照组治疗痊愈天数有明显差异性(P<0.05),观察组治疗效果优于对照组。提示氧气疗法配合炉甘石洗剂治疗新生儿臀红临床疗效显著。     

苦水玫瑰精油化学成份研究

本文研究了甘肃省苦水玫瑰精油的化学成份。并测定其物理化学性能,用毛细血管气相色谱和GC/MS联用法从苦水玫瑰精油中鉴定出48个组份,β-香茅醇和香叶醇的含量高达68%。用MS、IR和NMR等波谱法对这两个组份进行了解析确证。其理化特性与世界闻名的保加利亚玫瑰油十分接近。
