The synergistic study of Acacia Senegal (arabic gum) and Anacardium occidentale (cashew gum) combination in corrosion inhibition of mild steel was carried out to determine the inhibition efficiency of their combination. The gums were purified using standard methods and the blend prepared using the method as described by Femi – Oyewo et al. The blend was then used for corrosion study at two temperatures (303 K and 333 K) and the corrosion rates calculated. The adsorption process was found to satisfy the Langmuir isotherm and hence the sorption study reveals that the interaction is a physical one since the free energy of adsorption (ΔG^(o) ads kJ/mol) is given as (−16.47 and −15.61) kJ/mol at temperature T = 303 K and 333K accordingly. The GCMS technique was used to characterize the blend, five chemical compounds and their area percentage [6-O-(1-L-maloyl)-alpha-,beta-D-Glcp (veracylglucan A) (22.11%), 6-Octadecanoic acid (55.76%), Methylhexadecanoate (3.97%), 1-Pentadecane carboxylic acid (10.78%) and 9, 12-Octadecadienoic acid (7.38%)] were identified and subjected to computation corrosion study, the binding energy for the constituents of the blend on Fe surface were computed using Accelrys Material Studio and the mean values were found to be −327.097 kJ/mol, −446.943 kJ/mol, −602.826 kJ/mol, −608.625 kJ/mol and −693.749 kJ/mol respectively.

The conceptualization of the HousehoLd/Neighborhood Model for skilled nursing facilities began in 1987 at Evergreen Retirement Community in Oshkosh, WI, USA in the search for the ＂perfect＂ nursing home. Being able to see perfection required being freed from the mental constraints of regulations, reimbursement systems, and existing staff training programs so that visionary thinking was possible. ConceptuaLization was followed by a pilot project to test various aspects of the vision. The result was （1） a management philosophy built on Continuous QuaLity Improvement, （2） a team-based organization structure, （3） cross-functionaL staff roles, （4） sociaL-modeL activity programming, and （5） a residential style physical setting that won strong support from the State of Wisconsin. With this support, we had the opportunity to open in 1997 the first fuLL-scaLe model of a HousehoLd/Neighborhood in the United States based upon providing ＂resident and relationship centered services and care＂. The mode[ was validated through a year-tong evaluative research study. In 2004 we opened a second full-scale model incorporating significant improvements identified through experience. The opportunity to further develop the model has been provided through its adoption in China by China Senior Care, which wiLL open their first facility in 2014.

In the last few decades, several monitoring systems integrated with water level detection have been the major research focus. Production boost and its sustainability depend mainly on sustainable water supply, measuring water level, and avoiding waste of water is an essential task for all stakeholders. Therefore, the aim of this paper is to design and implement a mobile phone-based remote control. This will be applied to control the operation of a submersible motor in a water tank. The water level in the tank is detected and the device remotely turns the motor pump on/off. The design process is accomplished by developing an android application that works on GSM technology to manage the filling of water tank. An AT89C51 microcontroller is used for the desired programming. At the transmitting end, sensor is used for level detection and GSM module is used to send the information to user. According to this information, user controls the on/off operation of the pump. A SIM card is required for its operation and it works on attention (AT) commands. After the design and implementation of the device, the test results showed that all features of the device worked properly, and the device functions exactly as expected. More significantly, the paper has shown that ultrasonic sensors can be used to determine the level of water in a water tank and a GSM module can be used to control a submersible pump. The design and implementation of this device can help to reduce waste of time and power. Ultimately, it avoids water wastage thereby ensuring availability, conservation, and sustainability of water supply.

AIM: To appraise the current evidence for prophylactic oophorectomy in patients undergoing primary curative colorectal cancer ***: Occult ovarian metastases may lead to increased mortality, therefore prophylactic oophorectomy may be considered for women undergoing colorectal resection. A systematic review and meta-analysis wasperformed for English language studies from 1994 to 2014(PROSPERO Registry number: CRD42014009340), comparing outcomes following prophylactic oophorectomy(no known ovarian or other metastatic disease at time of surgery) vs no ovarian surgery, synchronous with colorectal resection for malignancy. Outcomes assessed: local recurrence, 5-year mortality, immediate post-operative morbidity and mortality, and rate of distant ***: Final analysis included 4 studies from the United States, Europe and China, which included 627 patients(210 prophylactic oophorectomy and 417 non-oophorectomy). There was one randomized controlled trials, the remainder being non-randomised cohort studies. The studies were all at high risk of bias according to the Cochrane Collaboration's assessment tool for randomised studies and the NewcastleOttawa Score for the cohort studies. The mean age of patients amongst the studies ranged from 56.5 to 67 years. There were no significant differences between the patients having prophylactic oophorectomy at time of primary colorectal resection compared with patients who did not with respect to local recurrence, 5-year survival and distant metastases. There was no difference in post-operative complications or immediate post-operative mortality between the ***: Current evidence does not favour prophylactic oophorectomy for patients without known genetic predisposition. Prophylactic surgery is not associated with additional risk of post-operative complications or death.

目的本研究尝试由护士对住院患者开展简短的饮酒问题早期干预,观察干预对于患者饮酒状况改善的情况。方法对北京某三级甲等医院的1019例住院内外科患者使用酒精依赖性疾患识别测验(AUDIT)进行饮酒状况的筛查,筛查出问题饮酒者,即危险饮酒者和有害饮酒者后,随机将其分为实验组(即早期干预组)和对照组,实验组患者接受护士有关饮酒问题的20min简短干预,1年后使用AUDIT随访实验组和对照组患者。结果实验组和对照组干预前后饮酒状况都有明显的改善(P<0.01),但实验组AUDIT总分下降的幅度显著高于对照组(P<0.05)。结论综合医院住院患者中有相当比例的患者属于危险饮酒或有害饮酒。护士开展的简短干预对于患者改善饮酒状况有一定的效果。但是如何修订更符合文化背景的干预内容,寻找改善饮酒问题的有效成分还需要进一步的研究。

企业对可持续性导向型管理的接受速度有多快？一项关于可持续性和创新的新研究表明,各企业分为两大清晰的阵营：“主动接受型”和“谨慎接受型”,并勾画出了一幅管理创新的未来印象。尽管全球经济和政治上的因素可能预示着可持续性管理的削弱,但实际上企业在可持续性管理上的投入越来越多了。总体看来,各企业都增强对可持续性管理的投入,但有一群组织正在以较其他企业远为激进的方式加大投入,在对可持续性管理策略的领导者（即“主动接受型”）和落后者（即“谨慎接受型”）之间出现了一道鸿沟。
