Published: September 2017

AbstractThe crystal structure of karibibite, Fe33+(As3+O2)4(As23+O5)(OH), from the Urucum mine (Minas Gerais, Brazil), was solved and refined from electron diffraction tomography data [R1= 18.8% forF> 4σ(F)] and further confirmed by synchrotron X-ray diffraction and density functional theory (DFT) calculations. The mineral is orthorhombic, space groupPnmaand unit-cell parameters (synchrotron X-ray diffraction) area= 7.2558(3),b= 27.992(1),c= 6.5243 (3) Å,V= 1325.10(8) Å3,Z= 4. The crystal structure of karibibbite consists of bands of Fe3+O6octahedra running alongaframed by two chains of AsO3trigonal pyramids at each side, and along c by As2O5dimers above and below. Each band is composed of ribbons of three edge-sharing Fe3+O6octahedra, apex-connected with other ribbons in order to form a kinked band running alonga. The atoms As(2) and As(3), each showing trigonal pyramidal coordination by O, share the O(4) atom to form a dimer. In turn, dimers are connected by the O(3) atoms, defining a zig-zag chain of overall (As3+O2)n-nstoichiometry. Each ribbon of (Fe3+O6) octahedra is flanked on both edges by the (As3+O2)n-nchains. The simultaneous presence of arsenite chains and dimers is previously unknown in compounds with As3+. The lone-electron pairs (4s2) of the As(2) and As(3) atoms project into the interlayer located aty= 0 andy= ½, yielding probable weak interactions with the O atoms of the facing (AsO2) chain.The DFT calculations show that the Fe atoms have maximum spin polarization, consistent with the Fe3+state.
Use of Regional Anesthesia for Outpatient Surgery Within the United States: A Prevalence Study Using a Nationwide Database
Authors: Gabriel Rodney A. , Ilfeld Brian M. 
Published: September 2017

BACKGROUND:
Regional anesthesia is of benefit for outpatient surgery given its demonstrated improvement in analgesia and decrease in complications, resulting in shorter average recovery room times and lower hospital readmission rates. Unfortunately, there are few epidemiological studies outlining the overall utilization of peripheral nerve blocks (PNBs) in this setting. Therefore, the primary objective of this study was to report the overall utilization of several types of PNBs among all candidate cases in the outpatient setting within the United States.

METHODS:
We identified all cases from the National Anesthesia Clinical Outcomes Registry that were performed as an outpatient surgery. We reported the frequency of various types of PNBs among all candidate cases, defined as cases that potentially could have received a PNB. Changes in prevalence of PNB utilization from 2010 to 2015 were analyzed by using logistic regression.

RESULTS:
Of the 12,911,056 outpatient surgeries in the National Anesthesia Clinical Outcomes Registry, 3,297,372 (25.5%) were amenable to a PNB. However, the overall PNB frequency was only 3.3% of the possible cases. The overall utilization for PNB of the brachial plexus, sciatic nerve, and femoral nerve were 6.1%, 1.5%, and 1.9%, respectively. The surgical procedures generating the highest volume of PNBs were shoulder arthroscopies and anterior cruciate ligament reconstruction, in which 41% and 32% received a PNB, respectively. During this time period, there was a significant increase in overall PNB utilization for both single-injection and continuous PNB (P < .0001). However, the proportion of continuous PNB to single-injection PNB did not increase significantly.

CONCLUSIONS:
While the overall frequency of PNB is relatively low, there was a significant increase in its prevalence during the study period. Regional anesthesia offers significant positive impact for perioperative outcomes and hospital efficiency metrics; however, it is not clear what is limiting its widespread use. Future studies are necessary to identify barriers and disparities in care to implement methods to increase regional anesthesia volume nationwide where beneficial and appropriate.

The exploding tumour on breast magnetic resonance imaging: an infected skin comedo
Authors: Tjalma WAA , Huizing MT 
Published: September 2017

A 61-year-old woman with a histologically proven invasive lobular carcinoma entered a clinical trial, which involved repeat magnetic resonance imaging (MRI). The protocol of the repeated MRI described a T4 breast cancer with involvement of the skin (Fig 1). There were only 17 days between the first and second MRI and during this short time it appeared that there had been rapid disease progression. On the initial MRI, a skin comedo could be seen in the left breast close to the tumour. The patient had squeezed the skin comedo, which had become infected. The second MRI captured the infected skin comedo, which had the appearance of an extensive breast cancer with skin involvement. The patient could be mismanaged if the clinician does not correlate the clinical findings with the radiological findings.

Published: September 2017

Introduction Short hospital stays and accelerated discharge within 72 hours following colorectal cancer resections have not been widely achieved. Series reporting on accelerated discharge involve heterogeneous patient populations and exclude important groups. Strict adherence to some discharge requirements may lead to delays in discharge. The aim of this study was to evaluate the safety and feasibility of accelerated discharge within 72 hours of all elective colorectal cancer resections using simple discharge criteria. Methods Elective colorectal cancer resections performed between August 2009 and December 2015 by a single surgeon were reviewed. Perioperative care was based on an enhanced recovery programme. A set of simplified discharge criteria were used. Outcomes including postoperative complications, readmissions and reoperations were compared between patients discharged within 72 hours and those with a longer postoperative stay. Results Overall, 256 colorectal cancer resections (90% laparoscopic) were performed. The mean patient age was 70.8 years. The median length of stay was 3 days. Fifty-eight per cent of all patients and sixty-three per cent of patients undergoing laparoscopic surgery were discharged within 72 hours. Accelerated discharge was not associated with adverse outcomes compared with delayed discharge. Patients discharged within 72 hours had significantly fewer postoperative complications, readmissions and reoperations. Open surgery and stoma formation were associated with discharge after 72 hours but not age, co-morbidities, neoadjuvant chemoradiation or surgical procedure. Conclusions Accelerated discharge within 72 hours of elective colorectal resection for cancer is safely achievable for the majority of patients without compromising short-term outcomes.
Constrained Allocation of Projects to Heterogeneous Workers with Preferences over Peers
Authors: Klijn Flip 
Published: September 2017

AbstractWe study the problem of allocating projects to heterogeneous workers. The simultaneous execution of multiple projects imposes constraints across project teams. Each worker has preferences over the combinations of projects in which he can potentially participate and his team members in any of these projects. We propose a revelation mechanism that is Pareto-efficient and group strategy-proof (Theorem 1). We also identify two preference domains on which the mechanism is strongly group strategy-proof (Theorem 2). Our results subsume results by Monte and Tumennasan (2013) and Kamiyama (2013) .
„Henne ensam lagen fällde“. Zur literarischen Verhandlung der Kindstötung und der Frage nach der (Mit-)Schuld der Väter
Authors: Wennerscheid Sophie 
Published: September 2017

AbstractThis article examines the literary representation of infanticides in Scandinavian literary texts from the 19th and 20th centuries. While most research on infanticide addresses the problematic situation of the mother who has killed her newborn child, the role of the father has suffered unwarranted neglect. It is therefore the purpose of this article to give an overview of central Scandinavian texts treating infanticides and to investigate more deeply how the father’s responsibility or guilt is discussed. Another important question is how law and justice are thematized in the texts. It will be argued that the literary texts take into account the fathers‘ (joint) guilt in the child’s death more often than commonly assumed. The article also shows that the literary texts do not take the androcentric perspective of the governing legislation for granted, but rather call it into question. It can thus be said that the literary texts on infanticide are implicitly critical of social institutions and legal norms for being ignorant of their own shortcomings.

Published: September 2017

AbstractCeCl3solution was used as a precursor to prepare CeO2microspheres by ultrasonic spray pyrolysis (USP). This is a green process that allows the transformation from CeCl3to CeO2without consuming any precipitant. The prepared material was investigated through various analysis technologies, such as X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), high resolution TEM (HRTEM), energy dispersive X-ray spectroscopy (EDS), N2adsorption-desorption and X-ray photoelectron spectroscopy (XPS). The prepared sample was confirmed as high purity CeO2microspheres, and two different microstructures were observed. The microsphere surface area was 86.5 m2/g according to the Brunauer-Emmett-Teller method. The microsphere diameter ranged from 0.09 μm to 3.86 μm and the microsphere surface was covered by numerous nanoparticles. The observed nanoparticles ranged in size from 19 nm to 200 nm as determined from FESEM and HRTEM images. The concentrations of Ce4+, Ce3+, residual chloride and oxygen vacancy in CeO2were studied by relative sensitivity factors based on the XPS results. Finally, the data suggested the possible formation mechanism of the CeO2microsphere structure.

Published: September 2017

Abstract
The lipophilic and hydrophilic extractives in the sapwood (sW) and heartwood (hW) of stems from Pinus halepensis Mill and Eucalyptus camaldulensis Dehnh trees grown in the north of Algeria were analyzed. The extraction of dried samples was carried out in an accelerated solvent extractor (ASE). The lipophilic substances were first extracted with n-hexane and then the hydrophilic ones with acetone/water. The extractives were analyzed by gas chromatography-flame ionization detection (GC-FID), GC-mass spectroscopy (MS) and high-performance size-exclusion chromatography (HPSEC). The largest amount of lipophilic extractives (≈13.4 mg g−1) was observed in the hW of P. halepensis, while the hW of E. camaldulensis contained the largest amount of hydrophilic extractives (≈116.3 mg g−1). Lipophilic extractives are mainly composed of oleoresins (resin acids, terpenes), fats (fatty acids, glycerides, steryl esters, sterols) and waxes (fatty alcohols). Hydrophilic extractives are composed of polyphenols (stilbenes, flavanols), sugars (monosaccharides) and sugar alcohols (cyclic polyols). The main identified lipophilic extractives are resin acids in pine and glycerides in eucalypt. The main identified hydrophilic extractives are cyclic polyols in pine and flavanols and monosaccharides in eucalypt. The total content of extractives is higher in hW than in sW.

AbstractBackgroundYouth friendly health services (YFHS) are services that attract, respond to the needs of and retain young people for continuing care. This study was conducted to determine the factors affecting utilization of government (GYFF) and non-governmental youth friendly facilities (NGYFF) in Lagos state, Nigeria.MethodsA descriptive cross-sectional study was conducted. A total of 543 adolescents aged 15–24 years, between August 1, 2014 and October 31, 2014 were consecutively recruited from 10 (five government and five non-governmental) youth friendly health facilities that had been in operation for at least 6 months prior to the study. Logistic regression was used to determine predictors of utilization of youth friendly health facilities.ResultsOverall, the mean age of respondents was 17.9 ± 2.8. However, the mean age of respondents at GYFF (18.5 ± 3.0) was significantly higher than those at NGYFF (17.1 ± 2.5) (p < 0.001). Of the 567 youths enrolled, 196 (34.6%) had good utilization of youth friendly facilities (YFF) (34% from the GYFF and 35.2% from the NGYFF). Marital status, school attendance, having a baby, satisfaction with visit, perception that information shared was kept confidential and accessibility of the youth friendly services were associated with utilization of YFF (p < 0.05). Confidentiality and access to facilities were predictors of utilization of YFF.ConclusionThere is poor utilization of both government and non-governmental youth friendly services in Lagos, Nigeria. There is a need for both the government and private sector to harmonize resources aimed at encouraging utilization of YFF in Lagos, Nigeria.

Abstract

Background
Sexual puberty in adolescents occurs before their mental and emotional maturity and exposes them to high-risk sexual behaviors. Because sexual risk-taking occurs before adolescents become involved in a sexual relationship, this study was conducted to identify the effect of group counseling based on self-awareness skill on sexual risk-taking among female high school students in Gorgan in order to suggest some preventative measures.

Methods
The present parallel study is a randomized field trial conducted on 96 girl students who were studying in grades 10, 11 and 12 of high school with an age range of 14–18 years old. Sampling was done based on a multi-stage process. In the first stage, through the randomized clustering approach, four centers among six health centers were selected. In the second stage, 96 samples were collected through consecutive sampling. Finally, the samples were divided into two intervention and control groups (each one having 48 subjects) through the simple randomized approach. It has to be noted that no blinding was done in the present study. The data were collected using a demographic specifications form and the Iranian Adolescents Risk-Taking Scale (IARS). The consultation sessions based on self-awareness skill were explained to an intervention group through 60-min sessions over 7 weeks. The pretest was conducted for both groups and the posttest was completed 1 week and 1 month after the intervention by the intervention and control groups. Finally, after the loss of follow-up/drop out, a total of 80 subjects remained in the study; 42 subjects in the intervention group and 38 subjects in the control group. Data analyses were done using SPSS v.16 along with the Freidman non-parametric test and the Mann-Whitney and Wilcoxon tests.

Results
The results showed that the sexual risk-taking mean scores in the intervention group (10.54 ± 15.64) were reduced by applying 1-week (8.03 ± 12.82) and 1-month (4.91 ± 10.10) follow-ups after the intervention. This reduction was statistically significant (p = 14%). However, no statistically significant difference was observed in the control group.

Conclusion
Group counseling based on self-awareness skill decreased the sexual risk-taking in girl students of the high school. As prevention is prior to treatment, this method could be proposed as the prevention of high-risk sexual behavior to healthcare centers and educational environments and non-government organizations (NGOs) interacting with adolescents.

Published: September 2017

Abstract
The paper presents a numerical study of the discharged heat water effect on the aquatic environment from the thermal power plant by using two water discharged pipes. It is solved by the Navier–Stokes and temperature transport equations for an incompressible fluid in a stratified medium. The aim of this study is to improve the existing water discharge system to reduce the heat load on the reservoir-cooler of the thermal power plants operation (Ekibastuz SDPP-1). In this study thermal pollution to the reservoir-cooler using only two water discharged pipes as so using the existing one and building only one additional in the eastern part of the reservoir-cooler is numerically simulated. The numerical method is based on the projection method which was approximated by the finite volume method. The numerical solution of the equation system is divided into four stages. The algorithm is parallelized on a high-performance computer. The obtained numerical results of three-dimensional stratified turbulent flow for two water discharged pipes of the thermal power plant were compared with experimental data and with numerical results for one water discharged pipe. General thermal load in the reservoir-cooler decreases comparing one water discharged pipe and revealed qualitatively and quantitatively approximately the basic laws of hydrothermal processes occurring in the reservoir-cooler can be seen that from numerical simulations where two water discharged pipes were used.

Authors: Li Yajun , Deng Feiqi , Li Jingzhao 
Published: September 2017

Abstract
The delay-dependent state estimation problem for Takagi-Sugeno fuzzy stochastic neural networks with time-varying delays is considered in this paper. We aim to design state estimators to estimate the network states such that the dynamics of the estimation error systems are guaranteed to be exponentially stable in the mean square. Both fuzzy-rule-independent and the fuzzy-rule-dependent state estimators are designed. Delay-dependent sufficient conditions are presented to guarantee the existence of the desired state estimators for the fuzzy stochastic neural networks. Finally, two numerical examples demonstrate that the proposed approaches are effective.

Published: September 2017

Abstract
This paper is an attempt to compare the nonlinear chiroptical and non-reciprocity effects of bi-isotropic media. The nonlinearity used is of a Kerr type. Following the approach of Mezache–Benabdelaziz, recently new nonlinear effects are characterized in a bi-anisotropic medium, which is due to the magnetization vector under the influence of a strong electric field. We then use these results to present the solution of nonlinear Schrödinger equation in the general case of bi-isotropic (chiral and non-reciprocal). Numerical simulations were carried out, in order to confirm the effect of the nonlinear chiroptical and non-reciprocity on the propagation analysis.

The aim of this review article is to provide the reader with information concerning the importance of Tunisian medicinal plants in the prevention and management of cancer and to open the door for the health professionals and scientists working in the field of pharmacology and therapeutics to produce new drug formulations to treat different types of cancer.
Interactional management of face-threatening acts in casual ELF conversation: an analysis of third-party complaint sequences
Authors: Konakahara Mayu 
Published: September 2017

AbstractThis paper investigates how English as a lingua franca is used to manage adversarial moments in casual conversation among friends, using conversation analysis and politeness theory. It presents a single case analysis of face negotiation devices utilized in two cases of third-party complaint sequences, in which complaints are made about someone else who is not present. The two cases to be analyzed were extracted from recordings of conversation of international students in British universities. The analysis revealed that the interactants utilize verbal and nonverbal devices, which are sometimes linguistically inexplicit but nonverbally resourceful, in a pragmatically sensitive manner in situ, thereby saving mutual face, intensifying the degree of face-threatening, or expressing disaffiliation in a face-saving way.
