Introduction: in-hospital infections cause significant morbidity and mortality. They affect approximately 45 % to 51 % of patients treated in intensive care. The intensive care unit (ICU) is a high-risk facility for the emergence and spread of multidrug-resistant organisms. The World Health Organization (WHO) classified pathogens of priority concern from level 1 to level 3.
Method: the study design was a retrospective observational cohort study. Data were collected from seventy clinical histories of the Hospital General de Agudos Donación Francisco Santojanni, located in the city of Buenos Aires, CABA, in the intensive care unit, during a period of 6 months.
Results: a review of 70 medical records was made, of which 14 records presented infections by multiresistant microorganisms, representing 20 % of them.
Conclusions: in-hospital infections will always be present, the important thing is to minimize them and assist them early, ideally to avoid them, so care must be taken in the organization of procedures with all aseptic measures

Nagari Batuhampar has several tourist attractions planned as object tourist destinations in the strategic plan. However, publication and presentation on social media are less effective in promoting the unique characteristics of tourist attractions. This research aims to identify the distribution of tourist destination objects in Nagari Batuhampar, followed by comprehensive information. The type of research used is descriptive survey research with the waterfall method, which consists of requirement analysis, system analysis, system implementation, system testing, system evaluation, operation, and maintenance. Data collecting techniques include observation using GPS and documentation, interviews to obtain information for web development, and questionnaires. Furthermore, the built-in data application QGIS 3.32.3” Lima” is open source. WebGIS, built using the Database Management System (DBMS) approach, is designed as software to manage big data. Big data is meant to be a collection of lots of data tailored to the project being carried out, such as mapping the distribution of public facilities and village potential. In this research, DBMS focuses on spatial data and religious and supporting tourism attributes. This is focused on data on religious and supporting tourism attributes. The result found that historical religious tourist attractions dominated the distribution of attractions in Nagari Batuhampar. The WebGIS of Tourist Destination Object was constructed using a waterfall method that was effectively created. This development was conducted through system evaluation tests, resulting in most respondents being satisfied with the process's performance.
What a Feeling: The Role of Immediate and Anticipated Emotions in Risky Decisions
Authors: Schlösser Thomas , Dunning David , Fetchenhauer Detlef 
Published: October 2011

ABSTRACTThe risk‐as‐feelings hypothesis argues that many risky decisions are not only predicted by anticipated emotions, as most consequentialistic decision making theories would presume, but also by immediate emotions. Immediate emotions refer to the “hot” visceral feelings people feel as they contemplate a specific decision option at the cusp of making a decision, whereas anticipated emotions are those emotions that people forecast that they will feel once they experience possible consequences of that decision. Four studies focused on the role of both types of emotions in decisions under risk and uncertainty. Decisions were substantively predicted by immediate emotional states beyond anticipated emotions or the subjective probability attached to outcomes. Thus, risky choices may be prompted, in part, by how people feel about the “riskless” portion of the decision—specifically, the various decision options they are contemplating—rather than the potential outcomes those options may produce.

ABSTRACTA simple and rapid liquid chromatography–mass spectrometry (LC‐MS) method was developed and validated for analysis of ginsenoside Rb1, Rb2, Rc, Rd, Re, Rf, Rg1, icariin and epimedin A, B, C in rat target tissues (spinal cord, brain, muscle and sciatic nerve) after intravenous administration of Jiweiling freeze‐dried powder using genistein as an internal standard (IS). The tissue samples were treated by protein precipitation with methanol prior to HPLC and chromatographic separation was performed on a C18 column utilizing a gradient elution program with acetonitrile and 0.1% formic acid aqueous. Electrospray ionization (ESI) source was employed and the 11 analytes and IS were detected by multiple reaction monitoring (MRM) scanning under the negative ionization mode. Higher sensitivity was achieved and the optimized mass transition ion‐pairs (m/z) for quantitation were selected. The calibration curves were linear over the investigated concentration ranges with correlation coefficients higher than 0.995. The intra‐ and inter‐day RSDs were all less than 10% with the relative error (RE) within ±9.3%. The mean extraction recoveries for all compounds were between 93.3 and 106%. The proposed method was successfully applied to investigate the target tissue distribution of the 11 compounds in rat after intravenous administration of Jiweiling freeze‐dried powder.

Mechanistic Insight into the Catalytic Activity of ββα‐Metallonucleases from Computer Simulations: Vibrio vulnificus Periplasmic Nuclease as a Test Case
Authors: Bueren‐Calabuig Juan A. , Coderch Claire , Rico Eva , Jiménez‐Ruiz Antonio , Gago Federico 
Published: October 2011

AbstractUsing information from wild‐type and mutant Vibrio vulnificus nuclease (Vvn) and I‐PpoI homing endonuclease co‐crystallized with different oligodeoxynucleotides, we have built the complex of Vvn with a DNA octamer and carried out a series of simulations to dissect the catalytic mechanism of this metallonuclease in a stepwise fashion. The distinct roles played in the reaction by individual active site residues, the metal cation and water molecules have been clarified by using a combination of classical molecular dynamics simulations and quantum mechanical calculations. Our results strongly support the most parsimonious catalytic mechanism, namely one in which a single water molecule from bulk solvent is used to cleave the phosphodiester bond and protonate the 3′‐hydroxylate leaving group.

Authors: Zou C. , Zhao P. , Lei Y. , Ye H. , Yao Y. , Chen M. , Wang T. 
Published: October 2011

AbstractAllyl‐β‐cyclodextrin is utilized to react with dimethyl diallyl ammonium chloride and acrylamide to synthesize a novel water‐soluble cationic polymer by redox free‐radical polymerization. The optimum polymerization conditions are determined by the single‐variable method, while the structure is characterized by Fourier transform infrared and scanning electron microscopy. In rheological experiments the polymer demonstrates superior properties compared to polyacrylamide. Interfacial tension and adsorption experiments prove the excellent performance of the polymer which can effectively decrease the interfacial tension and reduce the surfactant loss caused by stratum absorption in the process of polymer/surfactant flooding, thus indicating the potential application of the polymer for enhancing oil recovery.
Heat Transfer Augmentation and Entropy Generation Analysis of a Helically Coiled Tube with Internal Longitudinal Fins
Authors: Wang F. , Wang G.‐W. 
Published: October 2011

AbstractHeat transfer augmentation and entropy generation were investigated for a helically coiled tube with internal longitudinal fins. The Nusselt number, friction factor, thermal‐hydraulic performance ratio, and augmentation entropy generation number were calculated and analyzed. The results indicated that the internal longitudinal fins enhance the secondary flows and increase the temperature gradient near the tube wall, which in turn increase the heat transfer. It was found that the helically coiled tube with internal longitudinal fins provides the best integrated performance over the range of computed Dean numbers. The Nusselt number rised by 20–35 % with a corresponding 27–56 % increase of the friction factor. The computed results indicated that augmentation entropy generation numbers are approximately changed between 0.012 to 0.132 levels, i.e., the novel helically coiled tube with internal longitudinal fins is more efficient than that without internal fins.
Does Workforce Diversity Matter in the Fight against Climate Change? An Analysis of Fortune 500 Companies
Authors: Ciocirlan Cristina , Pettersson Caroline 
Published: October 2011

ABSTRACTThis paper asks whether more diverse companies are more committed to the fight against climate change than less diverse companies. Workforce diversity is measured along several socio‐demographic dimensions: age, gender, race, and presence in European Union countries. The paper develops the concept of Environmental Workplace Behavior, which explains how environmental attitudes and beliefs influence work decisions. The dependent variable is a climate change index calculated by a non‐profit organization, for a sample of Fortune 500 companies. A cross‐sectional research design is employed, using ordinary least squares (OLS) regression to analyze the data. The results suggest that companies that employ more women and have a stronger European presence tend to exhibit a higher concern for climate change. Companies do not seem to involve minorities and young people in meaningful decision‐making regarding climate change actions and initiatives. Future research might analyze other diversity dimensions, such as gender orientation, education, political liberalism, or religious affiliation.

Polypyridyl Metal Complexes with Biological Activity
Authors: Salassa Luca 
Published: October 2011

AbstractPolypyridyl metal complexes have optical properties that have been exploited in a wide range of biological and technological applications. Their structural diversity, chemical and redox properties provide a unique opportunity for designing new anticancer agents. Despite this great potential, relatively little is known about the cytotoxic effects of metal polypyridyl complexes, at least in comparison with other classes of coordination and organometallic compounds. This review uses selected examples to illustrate the most recent research carried out on this class of complexes as enzyme inhibitors and cytotoxic agents.
MEASURING THE EFFECT OF NAPSTER ON RECORDED MUSIC SALES: DIFFERENCE‐IN‐DIFFERENCES ESTIMATES UNDER COMPOSITIONAL CHANGES
Authors: Hong Seung‐Hyun 
Published: October 2011

SUMMARYThis paper measures the effect of Napster on record sales. I treat the introduction of Napster as a technological event that only Internet users experienced, and use a difference‐in‐differences (DD) approach. Because of potential compositional changes in Internet users, I examine identifying assumptions for the DD estimator under compositional changes and develop a test for identifying restrictions. To address potential bias due to compositional changes, I extend DD matching estimators to the case of two‐variate propensity scores. I find evidence suggesting that file sharing is likely to explain 20% of total sales decline, which is driven by households with children aged 6–17. Copyright © 2011 John Wiley & Sons, Ltd.
Spectral analysis of higher order differential operators with unbounded coefficients
Authors: Behncke Horst , Nyamwala Fredrick Oluoch 
Published: October 2011

AbstractHigher even order linear differential operators with unbounded coefficients are studied. For these operators the eigenvalues of the characteristic polynomials fall into distinct classes or clusters. Consequently the spectral properties, deficiency indices and spectra, of the underlying differential operators are superpositions of the contributions from the individual clusters. These results are based on a quantitative improvement of Levinson's Theorem. Our methods will also be applicable to other classes of linear differential operators.
The contribution of general and cancer‐related variables in explaining physical activity in a breast cancer population 3 weeks to 6 months post‐treatment

AbstractObjectivePhysical activity determinants are subject to change when confronted with the diagnosis of ‘cancer’ and new cancer‐related determinants appear. The aim of the present study is to compare the contribution of cancer‐related determinants with more general ones in explaining physical activity 3 weeks to 6 months post‐treatment.MethodsA theory‐based and validated questionnaire was used to identify physical activity levels (total and domain‐specific) and associated determinants among 464 breast cancer survivors (aged 18 to 65 years) 3 weeks to 6 months post‐treatment.ResultsDescriptive analyses showed higher scores for general determinants in comparison with cancer‐related determinants. Nevertheless, regression analyses showed that both general and cancer‐related determinants explained total and domain‐specific physical activity. Self‐efficacy, enjoyment, social support, lack of time and lack of company were important general determinants. The perception of returning to normal life, cancer‐related barriers (fatigue, lack of energy and physical side effects) and self‐efficacy in overcoming these barriers were important cancer‐related determinants. Although results differed according to the women's working status and the physical activity domain, general self‐efficacy explained most physical activity types in both groups.ConclusionComparable with the general population, enhancing breast cancer survivors' self‐efficacy in being sufficiently physically active seems to be important in physical activity interventions post‐treatment. However, interventions should be tailored to the experienced symptoms and working status of the women. Copyright © 2011 John Wiley & Sons, Ltd.
Fatal explosion caused by an intermittently used fuel gas piping system
Authors: Ogle Russell A. , Dillon Scott , Carpenter Andrew 
Published: October 2011

AbstractA fatal explosion occurred at a foundry during a routine test of an intermittently used liquid propane standby system. Just before the explosion, maintenance personnel were preparing the propane standby system for a startup test. While preparing for the startup test, the group was alerted that employees in an adjacent building had detected the odor of propane. The test was stopped, and the group conducting the test implemented emergency shutdown procedures. The explosion occurred during the execution of the emergency shutdown. The explosion resulted in three fatalities, numerous injuries, and extensive property damages.The propane standby system was intended to supply synthetic natural gas in the event of an interruption of the natural gas supply from outside utility company. Synthetic natural gas is a mixture of propane and air that has similar combustion properties to natural gas. To ensure the reliability of the propane standby system, it was scheduled for two routine maintenance tasks each year: a preventative maintenance task and a startup task. The liquid propane supply piping for the standby system was a buried pipe. When the underground propane piping was placed back into service for the test, flashing liquid propane discharged from an undetected hole in the pipe into loose backfill material in the surrounding soil. The propane vapor migrated underground and entered a nearby building through a penetration in the building foundation and was subsequently ignited. Following the incident, the buried liquid propane line was excavated, and the hole in the piping was discovered.This accident was caused by the failure of the mechanical integrity of the liquid propane piping. Within the body of this article, the root causes of the piping failure are discussed along with corrective actions that could have prevented this accident. The corrective actions include selecting an alternative material of construction for the piping, implementing proper construction practices for buried piping, following appropriate test and maintenance procedures for the existing cathodic protection system, and verification of piping integrity by leak testing with an inert gas before placing it into service. © 2011 American Institute of Chemical Engineers Process Saf Prog, 2011

AbstractThe Third International Workshop on thin film silicon solar cells (IWTFSSC‐3) was held on 11–14 October 2010 at ANA Hotel Nagasaki Gloverhill in Nagasaki, Japan (the first workshop was in Nara, Japan in 2007 and the second one in Berlin, Germany in 2009). This workshop mainly consists of invited talks and panel discussion on the present status and future prospects of thin film silicon photovoltaics (PV) technologies. The 50 participants include internationally most renowned experts. 50 reports were presented including 20 invited talks. Among these reports, 13 papers were selected to be published in this special issue.Driven by an increasing demand for PV, a shortage of crystalline silicon and the availability of turn‐key production lines, thin film silicon solar cells have been attracting increasing attention over the past few years. Many companies have invested in mass production lines for a‐Si and a‐Si/μc‐Si solar modules. A large number of these companies are still in the ramp‐up phase, or even before.Despite impressive growth of the thin film Si manufacturing capacity, many technological issues remain of importance. These include high deposition rate processes, large area uniformity, optical confinement, or laser scribing. To stay ahead of competing technologies, it will be important to address more fundamental and longer‐term issues as well, such as photo degradation of a‐Si, very high current cells, triple cells, new structures, or advanced transparent conductive oxides (TCOs).It is the aim of this workshop to address these and other topics, and to discuss them in an informal atmosphere with other experts. All participants vigorously exchanged their ideas leading to significant progress in important issues in thin film silicon solar cells.Thanks to the organizers and participants, there was an excellent blend of research reports from industry and academia and research reports worldwide (© 2011 WILEY‐VCH Verlag GmbH & Co.

Photovoltaic effect of BiFeO3/poly(3‐hexylthiophene) heterojunction
Authors: Liu Zhike , Yan Feng 
Published: October 2011

AbstractThe photovoltaic effect of the heterojunction based on multiferroic material BiFeO3 and organic semiconductor poly(3‐hexylthiophene) has been studied for the first time. A typical rectifying J–V characteristic of the heterojunction is observed with a rectifying ratio of ∼103. The power conversion efficiency of the device is comparable to those of hybrid solar cells based on poly(3‐hexylthiophene) and other oxide semiconductors, such as TiO2 or ZnO, indicating that BiFeO3 is a promising material for photovoltaic devices.

Lock‐in technique applied to cathodoluminescence of biomedical specimens in the SEM
Authors: Bröcker W. , Hauck G. , Wefgelt H. , Pfefferkorn G. 
Published: October 2011

AbstractVery low signals or disturbances by unwanted, foreign signals often lead to a restriction in the application of the cathodoluminescence (CL) method in the scanning electron microscope (SEM). This is even true if one uses an optimal CL detection system. We, therefore, introduced the lock‐in‐amplification technique, which has proved very successful in investigations of semiconductor materials into the biomedical field. After attaching the lock‐in system to our SEM which has a special CL equipment, we found that this technique could remove the disturbance caused by the light emitted from the heated filament, which can be reflected into the CL detector. Specimens on polished Al‐stubs or on Au‐coated glass slides could be imaged with improved contrast. The same was true if we measured the wavelengths of the CL. A general improvement of the signal‐to‐noise ratio in all specimens could not be detected. However, the beam current could often be reduced when using the lock‐in technique without a decrease in the quality of the CL image. A disadvantage of the commercially available lock‐in amplifier is that pictures need a longer exposure time than without lock‐in amplification.
