分离出了一种具有高度缓蚀作用的新喀里多尼亚弧菌,通过电化学测量方法和表面分析技术研究了该细菌对Cu在人工海水中腐蚀行为的影响。结果表明,新喀里多尼亚弧菌使Cu的开路电位明显负移;在有菌介质中,Cu表面的阻抗值显著增大;同时腐蚀电流密度明显降低,说明该细菌可以抑制Cu在人工海水中的腐蚀。CLSM结果显示,Cu表面吸附有大量的细菌,而SEM观察到Cu表面生物膜并不多,说明这种抑制作用是由吸附在Cu表面的细菌引起的,而与Cu表面的生物膜关系不大。

Background and Purpose: Researchers’ incomplete perception of the concerns about childbearing decision making process is revealed in discussions about policies and programs that are designed to influence fertility. Perceiving the concerns of women is essential to explain process of decision making for childbearing. This study aimed to understand women’s main concerns about childbearing decision making. Methods: This qualitative study was performed by conventional content analysis approach. The participants included 22 married women in Tehran who were pregnant for the first time or were using contraceptive methods. Purposeful sampling began and continued up to data saturation. To collect data, the unstructured in-depth interviews were used. Data were analyzed using qualitative content analysis by Lundman and Graneheim method. Findings: Four categories were obtained from data including “fear”, “uncertainty”, “hope” and “financial security”. The main category or theme was “concerns about one’s own future or securing child’s future” that was extracted as the main concern of women about childbearing decision making process. Conclusion: The findings of this study suggest that concerns about one’s own future or securing child’s future are the main concerns of women about childbearing decision making. Deep understanding of women’s concerns about childbearing will help midwives and other service providers to provide services, strategies and more sensitive and appropriate interventions.

Chinese Journal of Traumatology 2017年第2期20卷 67-74页

作者： masoumeh Abedzadeh-Kalahroudi Ebrahim Razi Mojtaba Sehat Mohsen Asadi-Lari Trauma Research Center Kashan University of Medical Sciences Kashan lran School of Public Health Iran University of Medical Sciences Tehran Iran

Purpose： To evaluate the return to work （RTW） rate, time and predictors among trauma patients using survival analysis. Methods： This cohort study was conducted with a three-month follow-up on 300 trauma patients hospitalized in Shahid Beheshti Hospital, Kashan, Iran in 2014. The data were collected through con- ducting interviews and referring to patients＇ medical records during their hospital stay and follow-up information at one ＆ three months after discharge from hospital. Final analysis was conducted on the data retrieved from 273 patients. Data were analyzed by chi-square test, Mann Whitney U test and survival analysis method. Results： The rate of RTW at the end of the first and the third follow-up months was respectively 21.6% and 61.2%. Survival analysis showed that the RTW time （Time between admission to first return to workl was significantly longer among patients with illiteracy, drug abuse, hospitalization history in the intensive care unit, low socioeconomic status, non-insurance coverage, longer hospital stay, multiple and severe injuries as well as severe disability. Conclusion： Our findings indicated that trauma has profound effects on the rate and time of RTW. Besides disability, many personal and clinical factors can affect the outcome of RTW.

从位于中国东海的钢铁研究总院舟山海洋腐蚀研究所近海海域的海底沉积物中分离提取得到杀鱼假交替单胞菌,分别将其接种到细菌培养广口瓶和模拟海水流动环境培养器中,利用电化学工作站、扫描电镜及红外光谱仪对浸泡于两种培养体系中Q235碳钢样品的腐蚀行为进行研究。结果表明,杀鱼假交替单胞菌能抑制碳钢在海水中的腐蚀进程。样品的阻抗在广口瓶培养体系中得到了更为明显的提高,广口瓶培养体系中的碳钢样品表面覆盖着一层质地均匀且完整的生物膜;而模拟海水流动环境中碳钢样品表面的生物膜厚度不均匀,海水通过膜层上的孔洞和裂隙与未成膜基体直接接触,在生物膜与样品表面之间形成氧浓差微电池使得局部腐蚀得以发展。红外光谱分析结果显示,培养7 d后两个体系中碳钢样品表面的生物膜内细菌的分泌物大分子不同。

作者： masoumeh Mahbouby Niyeh Alireza Jafarirad Jalal Karami Saeed Jabbari Bokani Department of Geology Islamic Azad University Science and Research Branch Tehran Iran Department of Geography Tarbiat Modares University Tehran Iran Department of Geomatics Geological Survey of Iran (GSI) Tehran Iran

The reason of this research is to identify the favorable areas for copper, zinc, and lead mineralization in the western part of the 1:100,000 Tafresh geological Sheet in the Urmia-Dokhtar structural zone of Iran. Effective data layers for mineralization, such as geology, geochemistry, structures, and satellite images, were analyzed and then integrated using the AHP-OWA method to identify favorable areas. Geochemical stream samples were analyzed by univariate, multivariate, and classical statistical methods and revealed the first, second, and third class anomalies for copper, zinc, and lead in the study region. Detection of hydrothermal alteration zones by Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite imagery in various algorithms, such as Relative absorption Band Depth (RBD), Minimum Noise Fraction (MNF), and Least Square Fit (LS-Fit), shows that argillic, phyllic, propylitic, and iron oxide alterations develop around the faults in the area under study. The favorable areas for copper, zinc, and lead mineralization have been identified by a combination of evidence maps of lithology, faults, dikes, geochemistry, and alteration data layers. Field observations in the area under study have confirmed the results.

从位于中国东海的舟山海域海底沉积物中分离提取得到4种细菌,分别为弧菌、威尼斯不动杆菌、河流弧菌及咸海鲜芽孢杆菌。采用电化学测量和表面分析技术研究了外加磁场下纯Cu在4种混合细菌溶液中的腐蚀行为。结果表明,磁场对细菌生长无明显影响,但影响Cu表面生物膜的结构与成分,加快生物膜形成与剥落的速率,且磁场越大,附着速度越快。随着磁场增大,生物膜中脂质含量减少,生物膜组成由脂质、蛋白质、碳水化合物转变成蛋白质和碳水化合物,且蛋白质含量降低,碳水化合物含量增多。施加磁场,样品在溶液中的Rct值明显提高,腐蚀电流密度减小,同时表面的点蚀程度减弱,表明磁场可以抑制Cu的微生物腐蚀进程,且磁场强度为60 mT时比28 mT时更能明显抑制Cu的腐蚀。

Anxiety is one of the psychological problems in pregnant women that sometimes takes the form of pathological and affects the mental health of mother. The aim of this study was to determine the effects of fetal movement counting on mental health of mother. In a randomized-controlled trial, 208 nulliparous women were randomly divided into two groups. At 28th weeks, both groups completed the GHQ-28. Then the intervention group started to count fetal movements from 28th to 37th weeks of gestation and the control group received routine prenatal care. Again, both groups completed the questionnaire at 37 weeks＇ gestation and the results were compared. Analysis was performed by SPSS and a P value 〈 0.05 was considered significant. The mean scores of mental health of mothers in 28th and 37th of pregnancy was respectively 23.52 ± 10.23 and 21.09 ± 10.12 in the intervention group and the difference was significant （P = 0.025）. The mean in the control group was 23.69 ± 9.43 and 23.88± 8.60 respectively, and the difference was not significant （P = 0.52）. In comparing the mean scores between the two groups, it was found that the difference was not significant at 28th weeks of gestation （P = 0.37）, but it was significant in 37th week （P = 0.002） and the counting of fetal movements could improve the mental health of mothers compared to control group. The women who had fetal movements counting at weeks 28 to 37 Of gestation reported better mental health than the control group. The mother renorted concerns about decreased fetal movement was similar in the two grouns.
