Authors: Castro B. , Bastida F.D. , Segovia T. , López Casanova P. , Soldevilla J.J. , Verdú-Soriano J. 
Published: December 2017

Objective: Oxidative stress can contribute to impaired wound healing and chronic wounds. Our objective was to test the results of a new antioxidant dressing that could help stop the oxidative stress of cells in the wound bed. Method: A multicentre, prospective case study series was conducted in three Spanish hospitals. The RESVECH 2.0 index was used for healing assessment. Data from each patient was collected by the attending clinical researchers. Data analysis was performed using the statistical concept intention-to-treat (ITT). Descriptive results were presented as frequency and percentages for qualitative variables and mean, standard deviation (SD), range and median for quantitative variables. For analytical-inferential analyses, incidence of healing was calculated for chronic and acute wounds. Relative risk (RR) was used to establish the differences of healing between both types of wounds. Healing was represented by Kaplan-Meier survival curves, and these were compared using the log-rank test. Results: A total of 31 patients with hard-to-heal wounds were recruited. During the 8-week follow-up period, nine wounds (29%) completely healed, of which seven (77.8%) were acute and two (22.2%) chronic. The remaining wounds (22) showed a significant improvement after treatment with the antioxidant dressing. RESVECH 2.0 scores decreased an average of 10.16 points over the 8-week period. Conclusion: The antioxidant dressing could represent an alternative in the dressing landscape for many types of acute and chronic wounds.
Portrayal of professions and occupations on veterinary practice websites and the potential for influencing public perceptions
Authors: Kinnison Tierney 
Published: December 2017

Aim: Veterinary practice websites have the ability to attract and retain clients. They also have the potential to influence clients' perceptions of the veterinary team. This paper investigated ‘Meet the Team’ pages on UK practice websites to identify the current portrayal of veterinary professions and occupations. Method: One hundred random practices, treating any species, were selected from the RCVS' list of practices. Information on the team was collected. Results: Meet the Team pages existed on 82 websites. All Meet the Team pages included veterinary surgeons (VSs). Veterinary nurses (VNs) were included on 82.9% of pages. Of the 14 pages that did not include veterinary nurses, six pages belonged to practices which did employ veterinary nurses. ‘Other’ occupations (such as receptionists and administrators) were included on 90.2% of pages. Of the eight pages that did not include other groups, four belonged to practices which did employ other groups. According to their biographies, 76% of VNs are RVNs, 13% are qualified, while 11% had no indication of qualification. There was no significant difference between the proportions of individuals per profession who had photographs within their biographies, or between the focus of photographs per profession. VS's biographies were significantly longer than VN's. Conclusion: The analysis was largely reassuring. The majority of practices included all groups which make up their team. However, some do not, or put more emphasis on certain groups, which may influence clients' understanding and value for other members of the veterinary team. Some suggestions for Meet the Team pages are made.
Energy efficiency of rotary digesters
Authors: Golub G. A. , Szalay K. , Kukharets S. M. , Marus O. A. 
Published: December 2017

In this paper, a new technical solution is introduced for the substrate mixing in a digester. The novelty content lies in the direction changes of the gravitational forces that influence the movement of organic and mineral biomass fractions. Digester case is designed as a horizontal cylinder rotating around a horizontal axis. Digester rotates in water that is in the outer casing.
This design creates a lift force for rotating digester which reduces the load on the bearings. The friction is reduced and therefore it reduces the energy loss of digester rotation and mixing of the substrate.
FACTORS PREDICTING DIFFICULT LAPAROSCOPIC CHOLECYSTECTOMY
Authors: Ismaeil Deari , Salih Barham , Abdulla Karzan 
Published: December 2017

Background
Laparoscopic cholecystectomy has become the standard operative procedure for cholelithiasis, but there are still some patients requiring conversion to open cholecystectomy, mainly because of technical difficulty.
Objectives
To identify the prediction of difficult laparoscopic cholecystectomy.
Materials and Methods
Preoperative clinical, laboratory, and radiologic parameters of 249 patients, who underwent laparoscopic cholecystectomy, were analyzed for their technical difficulty. Parameters (male sex, abdominal tenderness, previous upper abdominal operation, sonographically thickened gallbladder wall, age over 65 years, preoperative diagnosis of acute cholecystitis, history of ERCP) were found to have significant effect in multivariate analysis.
Results
Overall 54 operations (21.7%) were difficult; 36 operations (14.5%) took long time and 18 patients (7.2%) required conversion to open cholecystectomy.
Conclusions
Conversion risk can be predicted to some extent. Patients having high risk may be informed and scheduled appropriately. An experienced surgeon has to operate on these patients, and he or she has to make an early decision to convert in case of difficulty.
SINGLE INCISION MULTI-PORT LAPAROSCOPIC SURGERY (SIMPLS), A NOVEL TECHNIQUE IN IRAQ
Authors: Almahfooz Nezar 
Published: December 2017

Background
Single incision laparoscopic surgery (SILS) is a natural evolution of minimally invasive surgery (MIS) era.The advent of SILS was in the field of gynecology 1969. The first published report in general surgery appeared in 1992 with appendectomies. The first report of SILS cholecystectomy came in 1997 in a letter to the editor in the British Journal of Surgery by Navarra.Curcillo et al., developed Single Port Access (SPA™) surgery in April 2007 as a novel and innovative platform of minimal access surgery. Saber et al. reported the first series of single-incision laparoscopic SG in 7 patients in 2008. SILS recently becoming an interest of both patients and minimally invasive surgeons. Purposes were esthetic (scarless surgery), minimize parietal trauma, less pain and fast patient postoperative recovery. Despite these advantages, there is a concerned report of complications. Aiming to overcome the SILS complications, this novel technique; Single Incision Multiport Laparoscopic Surgery SIMPLS innovated in Iraq.
Objectives
To introduce SIMPLS (Single Incision Multiport Laparoscopic Surgery) as a novel technique in Iraq and assess safety, cost, aesthetic and any associated complications. To evaluate its use in some advanced laparoscopic procedures.
Materials and Methods
SIMPLS is a single surgeon prospective study conducted from Aug. 2009- Dec. 2016, in four hospitals in Iraq with the same laparoscopic platforms. Technique tested in different laparoscopic operative procedures on 129 different cases.
Results
Cholecystectomy (n=76), sleeve gastrectomy (n=20), appendectomy (n=9), diagnostic laparoscopy (n=8), hydatid cystectomy liver (n=4), fundoplication (n=4), ovarian cystectomy (n=3), renal cystectomy (n=3), combined sleeve gastrectomy and hiatal hernia repair (n=1), and small bowel tumor(n=1). Time spend initiating ports ranging from 9-12 minutes. No much difficulty or struggle faced using standard laparoscopy instruments. Time spend in procedures noticed to be acceptable and less than SILS. P value couldn’t see any significant difference with SILS. No conversion was reported till today. The cosmetic outcome found to be extremely acceptable by patients.Specific complications and difficulties, one case difficult intra-corporal liver retraction, gall bladder retraction in a severely inflamed gall bladder, bleeding at (angle of His),hematoma and ecchymosis, no port incision infection, and no incisional hernia.
Conclusion
SIMPLS technique is introduced by the author as a novel procedure in IRAQ 2009. Similar technique started few years before in some countries in the word. Benefits of the procedure: technically feasible, reproducible for expert devoted surgeons, shorter time ports initiation, excellent esthetic results, lowest cost, not associated with incisional hernia. I advise wider practice, more trials to confirm these findings and I suggest it for interested experienced minimally invasive surgeons.

DA INSTANTIA CRUCIS AO EXPERIMENTO CRUCIAL: DIFERENTES PERSPECTIVAS NA FILOSOFIA E NA CIÊNCIA
Authors: Raicik Anabel Cardoso , Peduzzi Luiz De Quadro , Angotti José André Peres 
Published: December 2017

A existência e o significado dos experimentos cruciais são questões que não ostentam consenso na ciência e na filosofia da ciência. Duhem, Popper e Lakatos, por exemplo, apresentam posicionamentos antagônicos entre si e, inclusive, em relação à ideia de instantia crucis explicitada por Francis Bacon no Novum Organum. Este artigo visa resgatar a definição baconiana, reconhecendo que ela faz parte de uma postura filosófica distinta das teses contemporâneas, e discutir algumas concepções de experimento crucial tanto por filósofos da ciência, quanto por alguns estudiosos, como Newton. Ainda, apontar algumas reflexões para o ensino de ciências.

Published: December 2017

The purpose of this research is to understand the influence of investor reaction towards profit that measured by the earning response coefficient with the variable of conservatism accountancy, persistence of profit and the systematic risk at the company, which have high market capitalization and listed in the LQ 45 index. Population in the research are companies, which are listed in the LQ 45 index from the period of 2011 to 2015 that have complete financial information, and have financial notation in the form of Rupiah and excluded from the banking sector. The analysis method that being used is multiple linier regressions analysis and the result shows that conservatism accountancy partially significant affecting the Earning Response Coefficient. It shows that there is an investor reaction towards companies in the Index LQ 45, which applies conservatism accountancy in gaining profit. Profit persistence and the systematic risk is not significantly affecting earnings response coefficient.
The Determinants of Sell-side Analysts’ Forecast Accuracy and Media Exposure
Authors: Sorogho Samira Amadu 
Published: December 2017

This study examines contributing factors to the differential forecasting abilities of sell-side analysts and the relation between the sentiments of these analysts and their media exposure. In particular, I investigate whether the level of optimism expressed in sell-side analysts’ reports of fifteen constituents of primarily the S&P 500 Oil and Gas Industry1, enhance the media appearance of these analysts. Using a number of variables estimated from the I/B/E/S Detail history database, 15,455 analyst reports collected from Thompson Reuters Investext and analyst media appearances obtained from Dow Jones Factiva from 1999 to 2014, I run a multiple linear regression to determine the effect of independent variables on dependent variables. I find that an analyst’s forecast accuracy (as measured by the errors inherent in his forecasts) is negatively associated with the analyst’s level of media exposure, experience, brokerage size, the number of times he revises his forecasts in a year and the number of companies followed by the analyst, and positively associated with the analyst’s level of optimism expressed in his reports, forecast horizon and the size of the company he follows.
Les stratégies d’ajustement mises en place lors d’un plan de licenciement : le cas des cadres intermédiaires
Authors: Grima François , Brunel Olivier , de Becdelièvre Pauline 
Published: December 2017

Cet article vise à comprendre comment les cadres intermédiaires gèrent leurs rôles d’acteurs lors d’un plan de licenciement. Le cadre théorique du modèle transactionnel du stress est mobilisé auprès de 70 personnes interrogées (54 managers et 16 Professionnels en Ressources Humaines). En croisant l’orientation (salariés licenciés vs entreprise) et l’intensité (faible vs forte) de l’engagement, l’analyse fait ressortir 4 postures développées par les cadres intermédiaires pour tenir leur rôle d’acteur du plan de licenciement. Elle identifie également les ressources internes et externes mobilisées par le cadre dans ces ajustements. Dépassant les logiques explicatives unidimensionnelles survalorisant l’agent ou la structure, cette recherche précise les stratégies, tactiques et ressources utilisées et intègre les conséquences organisationnelles de la tenue du rôle d’acteur du licenciement par le cadre intermédiaire.
L’immersion du salarié dans une expérience de travail : conceptualisation et implications
Authors: Brillet Franck , Maubisson Laurent , Ndiaye Adama 
Published: December 2017

L’immersion est un concept qui trouve ses fondements en psychologie positive et qui est actuellement mobilisé au sein des sciences de gestion par le marketing et les systèmes d’information. À partir de ces travaux et partant du constat que la gestion des ressources humaines ne s’y est pas encore intéressée, les auteurs proposent de considérer ce concept dans le cadre de situations de travail. Ainsi, un modèle conceptuel est proposé et une étude empirique conduite auprès de 311 employés a été réalisée. Les résultats permettent de donner une définition de ce concept en GRH et montrent un lien très étroit entre l’immersion dans une situation de travail et l’engagement ; lien toutefois modéré selon l’âge et l’ancienneté dans le poste.

AbstractAchieving efficient bulk‐heterojunction (BHJ) solar cells from blends of solution‐processable small‐molecule (SM) donors and acceptors is proved particularly challenging due to the complexity in obtaining a favorable donor–acceptor morphology. In this report, the BHJ device performance pattern of a set of analogous, well‐defined SM donors—DR3TBDTT (DR3), SMPV1, and BTR—used in conjunction with the SM acceptor IDTTBM is examined. Examinations show that the nonfullerene “All‐SM” BHJ solar cells made with DR3 and IDTTBM can achieve power conversion efficiencies (PCEs) of up to ≈4.5% (avg. 4.0%) when the solution‐processing additive 1,8‐diiodooctane (DIO, 0.8% v/v) is used in the blend solutions. The figures of merit of optimized DR3:IDTTBM solar cells contrast with those of “as‐cast” BHJ devices from which only modest PCEs <1% can be achieved. Combining electron energy loss spectrum analyses in scanning transmission electron microscopy mode, carrier transport measurements via “metal‐insulator‐semiconductor carrier extraction” methods, and systematic recombination examinations by light‐dependence and transient photocurrent analyses, it is shown that DIO plays a determining role—establishing a favorable lengthscale for the phase‐separated SM donor–acceptor network and, in turn, improving the balance in hole/electron mobilities and the carrier collection efficiencies overall.

Published: December 2017

AbstractThe use of heterogeneous bimetallic Pd‐based nanocatalyst for directing the inactivated sp3 C−H coupling has been scarcely explored. This work reported the formation of symmetrical C−C bonds from the inactivated sp3 C−H bonds catalyzed by employing reduced graphene oxide supported PtPd@Pt porous nanospheres. The reaction of sp3 C−H activation proceeded under mild conditions without any solvent, ligand or directing group. It is a higher atom‐, step‐ and cost‐effectiveness strategy for developing heterogeneous catalysts in the synthesis of bibenzyls with various functional groups (e. g. aryl, alkyl, methoxyl, halogen, ester, and pyridyl).magnified image
Synthesis of Chiral Sulfonyl Lactones via Copper‐Catalyzed Asymmetric Radical Reaction of DABCO⋅(SO2)

Published: December 2017

AbstractIn the present work, an asymmetric copper‐catalyzed radical multi‐component cascade reaction of an unsaturated carboxylic acid, aryldiazonium tetrafluoroborate, and DABCO⋅(SO2)2 (DABSO) has been developed for the enantioselective synthesis of sulfonyl lactones. In this reaction, this SO2 surrogate, DABSO was applied for the first time in the construction of chiral compounds. This multiple‐step asymmetric radical reaction was carried out under mild conditions and tolerated a wide range of substrates, resulting in the corresponding sulfonyl lactones with up to 95% chemical yields and 88% ee. The current reaction enriches the research contents of DABSO, and provides a new and efficient strategy to chiral functionalized lactones bearing quarternary stereogenic center.magnified image
Nonclassical Hydrophobic Effect in Micellization: Molecular Arrangement of Non‐Amphiphilic Structures
Authors: Uchman Mariusz , Abrikosov Alexei I. , Lepšík Martin , Lund Mikael , Matějíček Pavel 
Published: December 2017

AbstractMicellization brought about by nonclassical hydrophobic effect invokes enthalpy as the driving force. Thus, the underlying molecular phenomena differ from the entropically dominated hydrophobic effect. In quest for a molecular‐scale understanding, we report on the molecular arrangement of nonamphiphilic structures of an anionic boron cluster compound, COSAN. We synergistically combine experimental (NMR and calorimetry) and theoretical (molecular dynamics and quantum chemical calculations) approaches. The experimental data support the mechanism of closed association of COSAN, where the self‐assembly is driven by the enthalpy contribution to the free energy. Molecular dynamics simulations in explicit solvent show that water molecules form a patchy network around COSAN molecules, giving rise to the strong hydrophobic self‐association. In the second solvation shell, water forms a slightly hydrophilic “spot” close to the C‐H segments of the cluster. The simulations further show a counterintuitive short‐range [COSAN]−∙∙∙[COSAN]− attraction and Na+∙∙∙[COSAN]− repulsion. Quantum chemical calculations reveal a major role of solvation in stabilizing the contact pairs. Further, the calculations show the parallel/X‐shape geometrical arrangements of COSAN dimers as the most preferred. Lastly, dihydrogen bonding are found to influence the structure of micelles. In summary, we provide a molecular view of nonclassical micellization that can be extended to other amphiphiles like boranes.

Published: December 2017

ObjectiveMixed neuropathologies are the most common cause of dementia at the population level, but how different neuropathologies contribute to cognitive decline at the individual level remains unknown. We quantified the contribution of 9 neuropathologies to cognitive loss at an individual level.MethodsParticipants (n = 1,079) came from 2 longitudinal clinical–pathologic studies of aging. All completed 2 + cognitive evaluations (maximum = 22), died, and underwent neuropathologic examinations to identify Alzheimer disease (AD), other neurodegenerative diseases, and vascular pathologies. Linear mixed models examined associations of neuropathologies with cognitive decline and estimated the proportion of cognitive loss accounted for by each neuropathology at a person‐specific level.ResultsNeuropathology was ubiquitous, with 94% of participants having 1+, 78% having 2+, 58% having 3+, and 35% having 4+. AD was most frequent (65%) but rarely occurred in isolation (9%). Remarkably, >230 different neuropathologic combinations were observed, each of which occurred in <6% of the cohort. The relative contributions of specific neuropathologies to cognitive loss varied widely across individuals. Although AD accounted for an average of about 50% of the observed cognitive loss, the proportion accounted for at the individual level ranged widely from 22% to 100%. Lewy bodies and hippocampal sclerosis also had potent effects, but again their impacts varied at the person‐specific level.InterpretationThere is much greater heterogeneity in the comorbidity and cognitive impact of age‐related neuropathologies than currently appreciated, suggesting an urgent need for novel therapeutic approaches that embrace the complexity of disease to combat cognitive decline in old age.
