Optoelectronics Letters 2025年第1期21卷 21-27页

作者： Sura h.AL-REKABI A.A.ALWAhIB Electrical Technique Department Al Suwayrah Technical Institute Middle Technical University Laser and Optoelectronics Department University of Technology-Iraq

A process for purifying aqueous solutions containing heavy and toxic metals such as chromium（Cr） has been investigated. One of the extremely harmful pollutants in rivers and seawater is the heavy metal ions due to their direct impacts on human, animals and plants are hexavalent Cr（Ⅵ）. Consequently, highly sensitive sensor to detect Cr is essential. Surface plasmon resonance（SPR） technique has attracted huge research interest in detecting heavy metals specifically. In this study, three types of prism-based SPR sensor, gold（Au）/silver（Ag）, Au/polyaniline（PANI） and Au/titanium dioxide（TiO2） nanostructured films, are investigated as potential sensing material to detect the presence of Cr（Ⅵ） ions in water. The base Au layer with thickness of 48.3 nm is deposited on a glass slide for all sensors. For Au/Ag, Au/PANI nanofibers and Au/TiO2sensor films, the Cr（Ⅵ） concentration is varied from 1 ppm to 15 ppm with sensitivity of 0.270 °ppm-1, 0.082 °ppm-1and 0.039 °ppm-1, respectively. Based on these results, the Au/PANI nanofibers are the most sensitive to Cr（Ⅵ） among the tested sensing materials.

The Effect of Novel Low Energy Pulsed Light Combined with Galvanic Energy for home-Use hair Removal of Dark Skin

引用

Journal of Cosmetics, Dermatological Sciences and Applications 2015年第4期5卷 283-290页

作者： michae. h. gold hela Goren Tennessee Clinical Research Center Nashville USA home Skinovation Ltd. Yokneam Israel

Background and Objectives: Permanent reduction of unwanted hair on skin types V and VI is the most challenging procedure among all hair removal technologies based on selective absorption of light or laser. The objective of this study is to evaluate the safety and efficacy of a low energy pulsed-light device combined with galvanic energy, intended for home-use hair removal on dark skin. Materials and Methods: Fifteen women with skin types V and VI and dark terminal hair in axillaarea self-administrated 6 treatments at 2 week intervals, using a hand-held IPL combined with galvanicenergy device, using hPL (home Pulsed Light) technology. hair count and photographs were performed pre-treatment and 1 and 3 months after the last sixth treatment. Adverse events and subject satisfaction scores were recorded. Results: All patients showed a positive clinical response to treatment, with reduction of unwanted hair. hair counts were significantly reduced by 57.3% 1 month following last treatment and by 44.5% 3 months following last treatment. No adverse events were recorded. Subject satisfaction scores of the device usability and the treatment outcome were high. Conclusions: Low energy pulsed light combined with galvanic energy may be applied safely and effectively for at-home hair removal for people with dark skin types V and VI.

Clinical Evaluation of a Novel Blended Mode Diode Laser for hair Removal

引用

Journal of Cosmetics, Dermatological Sciences and Applications 2019年第1期9卷 19-29页

Introduction: Photoepilation by lasers is a popular procedure in aesthetic dermatology for removing unwanted body and facial hair. The use of the most appropriate laser wavelength is crucial as it affects treatment depth and melanin absorption. The three commonly used hair removal lasers are of specific wavelengths: 755 nm, 810 nm, and 1064 nm, each preferred certain types of skin and hair characteristics. The current evaluation reports the safety and efficacy of unique blended modes 755/810 nm and 810/1064 nm diode lasers for hair removal. Methods: hair removal results from 50 patients treated with the 755/810 nm handpiece and 50 patients treated with the 810/1064 nm handpiece were gathered from a few clinics. 3 treatments on various body areas were conducted 6 weeks apart and patients were followed up with 6 months after the last treatment. Results were evaluated by baseline, follow-up photographs, and hair counts. Results: Treatment area photos demonstrated hair reduction in the treated body and facial areas. Average hair count reduction at 6 months follow-up was 84% for the 755/810 nm handpiece and 81% for the 810/1064 nm handpiece. No significant or unexpected adverse events were detected in any of the patients. Conclusions: The novel blended mode hair removal diode lasers are proven to be safe and effective for hair removal in facial and body areas for patients of various skin types and hair characteristics.

Transport of gold by h_2S-rich oil field waters, and the origin of Carlin-type deposits

Chinese Science Bulletin 1999年第S2期44卷 161-162页

作者： Christopher h. Gammons Diane Wolfgram Montana Tech of the University of Montana Dept. of Geological Engineering Butte MT 59701 USA

DURING the course of hydrocarbon evolution and migration, large quantities of h 2S are often *** process is most familiar to petroleum geologists, and may lead to forming of natural gas deposits. Themost important h2S-forming reactions are bacterial sulfate reduction （BSR）, and thermochemical sulfatereduction （TSR）. Whereas BSR is restricted to relatively low temperature （hallowdepths, TSR becomes important at elevated temperature （>150℃） and greater depth of burial. Becauseh2S is highly soluble in water, any groundwater in the vicinity of a TSR-active zone will also become enriched in h2S. The central hypothesis of this paper is that hot groundwaters associated with TSR in carbonate terrains acquire the ability to transport gold and other elements （e.g. Ag, hg, As, Sb, Tl）

AIM： To investigate the clinicopathologic features which predict surgical overall survival in patients with proxima gastric carcinoma involving the esophagus （PGCE）. METhODS： Electronic pathology database established in the Department of Pathology of the Nanjing Drum Tower hospital was searched for consecutive resection cases of proximal gastric carcinoma over the period from May 2004 through July 2009. Each retrieved pa- thology report was reviewed and the cases with tumors crossing the gastroesophageal junction line were se- lected as PGCE. Each tumor was re-staged, following the guidelines on esophageal adenocarcinoma, accord- ing to the 7th edition of the American Joint Commission on Cancer Staging Manual. All histology slides were studied along with the pathology report for a retrospec- tive analysis of 13 clinicopathologic features, i.e., age, gender, helicobacter pylori （h. pylon} infection, surgical modality, Siewert type, tumor Bormann＇s type, size, dif- ferentiation, histology type, surgical margin, lympho- vascular and perineural invasion, and pathologic stage in relation to survival after surgical resection. Prognos- tic factors for overall survival were assessed with uni- and multi-variate analyses. RESULTS： Patients＇ mean age was 65 years （range： 47-90 years）. The male： female ratio was 3.3. The 1-, 3- and 5-year overall survival rates were 87%, 61% and 32%, respectively. By univariate analysis, age, male gender, h. pylori, tumor Bormann＇s type, size, histology type, surgical modality, positive surgical margin, lym- phovascular invasion, and pT stage were not predictive for overall survival; in contrast, perineural invasion （P = 0.003）, poor differentiation （P = 0.0003）, 〉 15 to- tal lymph nodes retrieved （P = 0.008）, positive lymph nodes （P = 0.001）, and distant metastasis （P = 0.005） predicted poor post-operative overall survival. Celiac axis nodal metastasis was associated with significantly worse overall survival （P = 0.007）. By multivariate analys

在草原科学中所已经建立的数学模型至少已达200个以上。数学模型的应用愈来愈广,它能更精确地说明草原科学若干本质及其规律。这是数学与草原科学巧妙结合的结果。但是对于这两者如何结合,在结合中应具有什么基本概念,并不是所有打算使用模型的人都正确理解的。为此,我们邀请了兰州大学秭佩同志就h.J.苟尔德著《生物系统的数学模型》的有关部分译出,以飨读者。原著深入浅出,文字隽永。译文也流畅易读。这是一篇分量颇重而并不枯燥的科学论文。
