1紫外线杀菌的原理介绍1.1紫外线杀菌原理紫外线用于消毒、杀菌已经很多年了,细菌的细胞中含有细菌的遗传信息核酸DNA和RNA,当核酸被紫外线照射时会大量地吸收紫外光,从而就会在体内形成一部分的间二氮杂苯(主要构成为蛋白酶)和间二氮杂苯的异构体.这种物质会使细菌自身的新陈代谢机能出现障碍,并且会导致细菌的遗传性出现问题,而持续的紫外线照射,最后就会导致因为上述原因所造成的细菌群体的死亡.此外,紫外光除了杀菌的用途外,也可用于让微生物降低自身的'活动性',有些细菌在可见光的照射下是比较活跃的,我们称之为'光恢复'特性,也就是说,在波长为300～500nm的可见光下,细菌自身有一种光恢复酶素会让细菌种群变得很活跃,自身会大量繁殖.所以,当需要控制这种细菌的数量及种群时,则可以考虑用微弱的紫外线进行照射,将细菌的数量控制在一定范围之内.

日本稻瘟病发生及防治现状

农药译丛 1989年第2期11卷 27-30页

日本稻瘟病发病情况在日本,由稻梨孢(稻瘟病菌)引起的稻瘟病在病害中最为严重,尽管受害面积和发病率随栽培期气候条件因年而异。然而,如(图1,略)所示,自1976年以来,除了1980年叶瘟和穗颈瘟病情严重及1984年叶瘟大面积发生外,受害面积的... 详细信息

日本稻瘟病发病情况在日本,由稻梨孢(稻瘟病菌)引起的稻瘟病在病害中最为严重,尽管受害面积和发病率随栽培期气候条件因年而异。然而,如(图1,略)所示,自1976年以来,除了1980年叶瘟和穗颈瘟病情严重及1984年叶瘟大面积发生外,受害面积的总趋势是在减少。日本稻瘟病的发生和病情发展过程已基本清楚。在最低气温高于16℃以及当日和次日有雨时,水稻田会初次受到稻瘟病菌的侵染。正常年份中,日本北部水稻田叶瘟病斑一般在六月底七月初首次出现,那些地区大多在五月底前插秧。

Organometal trihalide perovskite-based solid-state hybrid solar cells have attracted unexpected increasing interest because of the high efficiency(the record power conversion efficiency has been reported to be over 17%)and low cost for preparation.1)The high efficiency was thought to mainly originate from the strong optical absorption over a

用分光反射光谱(SR)和分光椭偏光谱(SE)来分析低温激光退火多晶硅薄膜的光学特性。利用多层光学和Braggeman有效介质近似模型(B-EMA),对薄膜光学常数和结构参数(膜厚度,表面粗糙度和非均匀性)的退火功率依存关系进行解析。解析结果表明,有一个临界退火功率存在。退火达到这个功率时,多晶硅薄膜的光学常数非常接近单晶硅。由于受增大晶粒尺寸影响,在这个功率时,薄膜表面粗糙度和非均匀性也显示了一峰值。在整个退火区域,膜厚度有大约8%变化。

作者： C. Zhao H. Okada M. Asakawa R. Sugimoto K. yoshino School of Environmental Science and Engineering Kochi University of Technology Kochi Japan Shimane Institute for Industrial Technology Matsue Japan.

Methyl methacrylate (MMA) was grafted onto silk fiber in a one-step emulsion system using a diethylzinc and 1,10-phenanthroline complex. The reaction conditions were investigated by varying temperature and initiator to monomer ratio. Fourier transform infrared (FTIR) spectrum, thermogravimetric analysis (TGA), and scanning electron microscopy (SEC) techniques were used to characterize the structure, thermal stability, and surface morphology of the obtained product, respectively. Grafting of MMA onto silk increased the thermal stability of silk. The FTIR spectrum and SEM images provided further evidence that MMA has been successfully grafted onto the silk fiber. A peak ascribed to the C=O stretching vibration of MMA was detected in the FTIR spectrum of grafted silk fiber, which was not present in the spectrum of pure silk fiber. Moreover, the SEM images illustrated the increase in diameter and surface roughness of grafted silk compared with pure silk. Lastly, the dyeing performance of the modified silk was significantly increased.

Open Journal of Gastroenterology 2013年第5期3卷 276-280页

作者： Takatoshi Kitazawa Yusuke yoshino Ichiro Koga Akari Isono Takatsugu Yamamoto Yasushi Kuyama Yasuo Ota Department of Internal Medicine Teikyo University School of Medicine Tokyo Japan

Objective: The incidence of Clostridium difficile-associated diarrhea (CDAD) has increased in many developed countries. In addition to previous use of antimicrobials, use of proton pump inhibitors (PPIs) is thought to increase the incidence of CDAD. However, most previous studies that showed a positive relationship between PPI use and CDAD were conducted retrospectively in Western countries. We investigated whether the use of PPIs increases the incidence of CDAD in Japan. Methods: The study was carried out with all the patients admitted to the department of internal medicine of Teikyo University Hospital from April 2009 to June 2009. Clinical data were obtained from medical records. CDAD was defined as detection of CD toxin from stool samples in diarrheal patients. PPI users were defined as patients that were prescribed with PPI for more than 30 days at the detection of CD toxin. The results of Clostridium difficile (CD) toxin were collected until April 2011. Results: A total of 793 patients were included, and PPIs were prescribed to 489 patients (59.8%). The average age of PPI users was higher than that of PPI nonusers (68.9 vs. 63.1 years). Among the 489 PPI users, 19 patients developed CDAD, while 4 developed CDAD among the 304 PPI nonusers. The relative risk of PPI use on the incidence of CDAD was 3.20 in univariate analysis (95% confidence interval, 1.10 to 9.32, p = 0.04), although the hazard ratio in multivariate analysis was 1.23 (95% confidence interval, 0.35 to 3.83, p = 0.82). Conclusions: There was no association between CDAD occurrence and PPI use in patients in Japan.

INTRODUCTION: Gait asymmetry can become very pronounced in patients who have suffered a stroke. The impairment of trunk function in some stroke patients can restrict thorax mobility and cause respiratory muscle weakness. Trunk and neck dysfunction are believed to affect the gait in stroke patients. OBJECTIVE: This study aimed to investigate the relationship between gait asymmetry and respiratory function in stroke patients by measuring the step time and trunk acceleration. METHODS: This study employed a cross-sec- tional design. Thirty stroke patients participated in this study. The symmetry index (SI) and Lissajous index (LI) were used to evaluate asymmetry during walking. The respiratory function and respiratory muscle strength were evaluated by spirometry. We examined the relation between SI or LI and the respiratory function/respiratory muscle strength in patients with stroke. RE-
