Investigation of mechanical properties and fatigue life of ECARed AA5083 aluminium alloy
Authors: Sedighi M , Monshi P , Joudaki J 
Published: February 2017

AbstractEqual‐channel angular rolling (ECAR) is a continuous severe plastic deformation process. In this process, severe shear strains apply to the sheet. This strain increases the yield or ultimate strength of sheet without significant change in sheet dimension. In this paper, the effect of ECAR process on mechanical properties and fatigue life of manufactured sheets will be studied. Four AA5083 samples have been prepared and annealed for obtaining stress‐free samples. Three samples have been rolled by the ECAR process with one, two and three passes of rolling, respectively. Mechanical tests including tensile test, hardness and axial fatigue tests have been carried out on prepared samples. Fatigue tests have been implemented according to a strain‐based approach with a constant strain ratio equal to 0.75 and 0.5 Hz frequency of loading. All of the tests have been carried out in controlled laboratory conditions. Results show that the ultimate tensile strength of samples increases with increasing the pass of rolling. Also, the maximum elongation of samples decreases. Maximum elongation was 17% in annealed samples, while it decreases to 10% in samples with three passes of rolling. The hardness of samples has been measured, and the results show an increase in hardness for a higher pass of the ECAR process. Fatigue test results show that fatigue life of AA5083 samples decreases in manufactured sheets of the ECAR process. Also, cyclic softening has been observed in the ECARed sample. The fracture surfaces of samples after fatigue test have been observed with a scanning electron microscope. A comparison of fracture surfaces confirms that the crack growth was intergranular in annealed samples while it changes in ECARed samples to transgranular.

Published: February 2017

AbstractObjectiveTo investigate the knot holding capacity (KHC) of pattern‐ending square, surgeon's and Aberdeen knots each tied in 4 throw combinations using large gauge suture after exposure to media commonly found in equine abdominal surgery.Study designIn vitro mechanical study.Sample population: Knotted suture strands (n = 10/group).MethodsStrands of 2 polydioxanone or 3 polyglactin 910 were exposed to 1 of 4 media for 15 minutes. Control suture strands remained dry. Media used included balanced electrolyte solution, 1% sodium carboxymethylcellulose, equine serum, or equine fat. Pattern‐ending knots for the 3 knot configurations were loaded to failure in a linear fashion on a materials testing machine to determine KHC.ResultsSurgeon's knots tied using media‐exposed 3 polyglactin 910 had a significantly higher KHC than the same dry knots with 5 and 6 throws. Square knots tied using media‐exposed to 3 polyglactin 910 had a significantly higher KHC than the same dry knots at 5 throws. Aberdeen knots tied with either media‐exposed 2 polydioxanone or 3 polyglactin 910 had a significantly higher KHC than their equivalent dry knots. Aberdeen knots had a superior KHC, while requiring less suture than both surgeon's and square knots.ConclusionMedia exposure either had no effect on KHC or significantly improved the KHC of all knots investigated. Based on KHC and knot volume, Aberdeen knots tied using media‐exposed 3 polyglactin 910 with 3 throws and 1 turn are recommended to end a continuous suture pattern.
Managing Talents in Higher Education Institutions: How Effective the Implementation of Succession Planning?

Published: February 2017

The organisations that are aware that human capital is one of their greatest treasured resources would have an impressive competitive mechanism. “Great vision without great people is irrelevant”. Organisations may choose to focus on financial capital, information technology, equipment, and excellent processes; but in the end, their personnel and individual employees are the most important. The contributions of employees are undeniable. To accomplish the objectives of the National Higher Education Strategic Plan, the government is trying hard to transform Malaysian Higher Education Institutions (HEIs) with the leadership development for top and middle-level management. This study investigated the effectiveness of sucession planning in HEIs. This study employed the stratified random sampling technique from the population of academics from public universities in Malaysia. The results determine that the sample mean of succession planning at α = 0.05 level of significance concludes that succession planning at Malaysian HEIs is effective. This result might answer the capability of HEIs in practising effective succession planning. The succession process should include the identification of a successor, the designation of a successor, the selection and training of the successor, the development of a vision or strategic plan for the firm following the succession, the definition of the role of the incumbent and the communication of the decision to key stakeholders.
Estrogen-dependent effects of 5-hydroxytryptophan on cortical spreading depression in rat: Modelling the serotonin-ovarian hormone interaction in migraine aura
Authors: Chauvel Virginie , Multon Sylvie , Schoenen Jean 
Published: February 2017

Background Cortical spreading depression (CSD) is the likely culprit of the migraine aura. Migraine is sexually dimorphic and thought to be a “low 5-HT” condition. We sought to decipher the interrelation between serotonin, ovarian hormones and cortical excitability in a model of migraine aura. Methods Occipital KCl-induced CSDs were recorded for one hour at parieto-occipital and frontal levels in adult male (n = 16) and female rats (n = 64) one hour after intraperitoneal (i.p.) injection of 5-hydroxytryptophan (5-HTP) or NaCl. Sixty-five oophorectomized females were treated with estradiol- (E2) or cholesterol- (Chol) filled capsules. Two weeks later we recorded CSDs after 5-HTP/NaCl injections before or 20 hours after capsule removal. Results 5-HTP had no effect in males, but decreased CSD frequency in cycling females, significantly so during estrus, at parieto-occipital (−3.5CSD/h, p < 0.001) and frontal levels (−2.5CSD/h, p = 0.014). In oophorectomized rats, CSD susceptibility increased during E2 treatment at both recording sites (+5CSD/h, p = 0.001 and +3CSD/h, p < 0.01), but decreased promptly after E2 withdrawal (−4.7CSD/h, p < 0.001 and −1.7CSD/h, p = 0.094). The CSD inhibitory effect of 5-HTP was significant only in E2-treated rats (−3.4CSD/h, p = 0.006 and −1.8CSD/h, p = 0.029). Neither the estrous cycle phase, nor E2 or 5-HTP treatments significantly modified CSD propagation velocity. Conclusion 5-HTP decreases CSD occurrence in the presence of ovarian hormones, suggesting its potential efficacy in migraine with aura prophylaxis in females. Elevated E2 levels increase CSD susceptibility, while estrogen withdrawal decreases CSD. In a translational perspective, these findings may explain why migraine auras can appear during pregnancy and why menstrual-related migraine attacks are rarely associated with an aura.

AbstractObjective:To evaluate the effect of fish oil supplementation on pregnancy outcomes in mother and newborn.Methods:This randomized, triple-blind, placebo-controlled trial was conducted on 150 pregnant women aged 18–35 years from Feburary 2014 to April 2015 in Tabriz, Iran. Participants were assigned to receive either 1000 mg fish oil supplements containing 180 mg eicosapentaenoic acid (EPA) and 120 mg docosahexanoic acid or placebo from week 20 of gestation to birth. The primary outcome measure was birth weight. Gestational duration, preterm labor low birth weight (LBW), length, head circumference, and maternal serum docosahexaenoic acid (DHA) and EPA level at 35–37 weeks were also examined. The statistical analysis was on an intention-to-treat basis.Results:Demographic characteristics were similar in both groups (P>0.05). The mean (SD) birth weight values in the fish oil and placebo groups were 3256 (362) g and 3172 (447) g, respectively (adjusted mean difference (MD)=84.1 g, 95% confidence interval [CI]=−24.8 to 193.2). Five (7.6%) neonates in the placebo versus no case in the fish oil group were born with LBW (P=0.02). The rate of preterm labor was lower in the fish oil group (adjusted OR=0.74, 95% CI=0.16–3.42). However, there were no statistically significant differences in the maternal outcomes (P>0.05) with the exception of the proportion of maternal serum DHA fatty acid at 35–37 weeks (P<0.001).Conclusion:Although low dose fish oil supplementation increased birth weight, its effect was not statistically significant. The frequency of LBW was significantly reduced in the intervention group, but the observed reduction needs to be confirmed in future larger investigations using different doses of omega-3.
Using GIS to discover changes in the local water cycle of wetlands – case study Poblockie Peatbog
Authors: Sikora Magda , Cieśliński Roman 
Published: February 2017

Abstract
The aim of this study is to reconstitute the changes in the local water cycle and plant habitats occurring in wetlands under anthropic influence. The selected area for the study in this paper is the swamp of Pobłockie Peatbog, located in the catchment area of the river Łeba in northern Poland. The fieldwork was performed in October of 2013. Using ArcMap the hydrographic network of the study area in the years 1837, 1918, 1936, 1976 and 2000 were digitized and represented. Using a LIDAR image, the terrain model for the swamp of Pobłockie Peatbog was generated in ArcMap. This was then used to create a map showing the location of runoff pathways from the waterlogged areas. Long-term drainage and the construction of new drainage ditches have led to the encroachment of bog woodland on the originally treeless swamp of Pobłockie Peatbog.
Comparison of experimental and theoretical results for the structure and elastic properties of moganite
Authors: Grimmer Hans , Delley Bernard 
Published: February 2017

Abstract
Moganite, which is monoclinic at ambient temperature, undergoes a displacive transition to an orthorhombic phase at ≈570 K. Whereas the monoclinic phase may be considered as α-quartz that is Brazil twinned along {1 0 1̅ 1} at the unit-cell scale (cell-twinning), the orthorhombic phase cannot be interpreted as a Brazil cell-twin of β-quartz, in contrast to statements made in the literature. The shape of the oxygen tetrahedra in monoclinic moganite has been determined more reliably by density functional theory (DFT) calculations than by experiment: the differences between the various experimental results for the shape of the oxygen tetrahedra at ambient temperature are typically ten times larger than the differences between the DFT results. The DFT calculations suggest that the oxygen tetrahedra in moganite are very close in shape to the oxygen tetrahedra in α-quartz. Among the three DFT calculations considered, the most convincing results for the bond angles in moganite are obtained for the DMol3 code with functional PBE.
Technology Focus: Mature Fields and Well Revitalization (January 2017)
Authors: Lee Jesse 
Published: February 2017

Technology Focus
In last year’s Technology Focus concerning mature fields, I highlighted the topics of refracturing, efficiency, and environmental responsibility. Evidently, these three topics remain as the critical aspects of mature-field development. However, for 2017, I would like to steer readers’ attention to new technology, advanced modeling, and the interesting topic of fracture hits.
Advanced modeling, the ability to capture reservoir information in high definition and translate the knowledge into mathematical expressions, has always been a key enabler that allows our industry to maximize well performance. For instance, advanced modeling allows much more thorough derisking of enhanced-oil-recovery investment and leads to the maximization of financial returns.
Concerning new technology that improves mature-field development, the advanced geosteering and reservoir-scale mapping tool not only enhances oil production from the target reservoir but also can help the asset team in proper reservoir characterization and redevelopment planning. It has been a challenge for our industry to implement new technology for the past 2 years because of market depression. However, 2017 is certainly the year to revisit the topic of new technology and prepare ourselves for the activity uptick.
In this feature, I would like to bring up the topic of fracture hits. While in-field drilling is becoming more common, this crosswell communication initiated while pumping a hydraulic-fracturing treatment seems to be inevitable. It is not entirely clear how to prevent or control this phenomenon. However, there are several years of data and publications regarding this matter, plus some new technology to minimize fracture hits. I believe this will open up new opportunities for further maximization of well production.
In this editorial, I talked about advanced modeling, new technology, and fracture hits. Therefore, I have selected several papers on these topics to share with you. Enjoy your reading.

OBJECTIVE
Many reports have successfully demonstrated that cervical disc arthroplasty (CDA) can preserve range of motion after 1- or 2-level discectomy. However, few studies have addressed the extent of changes in segmental mobility after CDA or their clinical correlations.

METHODS
Data from consecutive patients who underwent 1-level CDA were retrospectively reviewed. Indications for surgery were medically intractable degenerative disc disease and spondylosis. Clinical outcomes, including visual analog scale (VAS)–measured neck and arm pain, Neck Disability Index (NDI), and Japanese Orthopaedic Association (JOA) scores, were analyzed. Radiographic outcomes, including C2–7 Cobb angle, the difference between pre- and postoperative C2–7 Cobb angle (ΔC2–7 Cobb angle), sagittal vertical axis (SVA), the difference between pre- and postoperative SVA (ΔSVA), segmental range of motion (ROM), and the difference between pre- and postoperative ROM (ΔROM), were assessed for their association with clinical outcomes. All patients underwent CT scanning, by which the presence and severity of heterotopic ossification (HO) were determined during the follow-up.

RESULTS
A total of 50 patients (mean age 45.6 ± 9.33 years) underwent a 1-level CDA (Prestige LP disc) and were followed up for a mean duration of 27.7 ± 8.76 months. All clinical outcomes, including VAS, NDI, and JOA scores, improved significantly after surgery. Preoperative and postoperative ROM values were similar (mean 9.5° vs 9.0°, p > 0.05) at each indexed level. The mean changes in segmental mobility (ΔROM) were −0.5° ± 6.13°. Patients with increased segmental mobility after surgery (ΔROM > 0°) had a lower incidence of HO and HO that was less severe (p = 0.048) than those whose ΔROM was < 0°. Segmental mobility (ROM) was significantly lower in patients with higher HO grade (p = 0.012), but it did not affect the clinical outcomes. The preoperative and postoperative C2–7 Cobb angles and SVA remained similar. The postoperative C2–7 Cobb angles, SVA, ΔC2–7 Cobb angles, and ΔSVA were not correlated to clinical outcomes after CDA.

CONCLUSIONS
Segmental mobility (as reflected by the mean ROM) and overall cervical alignment (i.e., mean SVA and C2–7 Cobb angle) had no significant impact on clinical outcomes after 1-level CDA. Patients with increased segmental mobility (ΔROM > 0°) had significantly less HO and similarly improved clinical outcomes than those with decreased segmental mobility (ΔROM < 0°).

Published: February 2017

Devido a crescente influência das Ciências Humanas na área da Educação Física que sempre se desenvolveu a partir dos ideais das Ciências Biológicas, passam a circular na área formas de se investigar o corpo que trazem em comum aspectos políticos, culturais e históricos. No bojo deste cenário encontra-se Michel Foucault. Este artigo investiga nas obras do mesmo e a partir de comentadores, como se dá a fundamentação do conceito de Corpo em seu pensamento. Entende-se a partir da análise, o Corpo como uma superfície material, concreta, na qual se instala diferentes formas de Sujeito fabricadas por tecnologias políticas específicas e históricas. Tal análise possui sua validade para uma melhor compreensão das problematizações realizadas no cenário contemporâneo da Educação Física.

Alfabetização e ética: um trabalho interdisciplinar de formação docente e discente
Authors: Carneiro Ana Lúzia Magalhães 
Published: February 2017

O trabalho sobre a temática da Ética proposto pelos Parâmetros Curriculares Nacionais (1997) é essencial para o desenvolvimento da autonomia de crianças e adolescentes. Entretanto, as dificuldades de aprendizagem principalmente no sistema público de educação, impõem práticas educativas focadas na leitura, escrita e cálculos básicos, em detrimento dos problemas da realidade das comunidades escolares. Quando as escolas decidem desenvolver projetos sobre as relações de desrespeito e o tipo de imagem que as crianças constroem de si e do “outro”, a área de História passa a assumir o trabalho de formação. Este artigo pretende discutir uma experiência vivenciada por professores e alunos dos anos iniciais do Ensino Fundamental, na qual a alfabetização e a ética constituíram-se como eixos para o desenvolvimento de um projeto de formação/ação docente e discente.

Published: February 2017

AbstractA one‐pot N‐Boc deprotection and catalytic intramolecular reductive amination protocol for the preparation of enantiomerically pure tetrahydroisoquinoline alkaloids is described. The iodine‐bridged dimeric iridium complexes displayed superb stereoselectivity to give tetrahydroisoquinolines, including several key pharmaceutical drug intermediates, in excellent yields under mild reaction conditions. Three additives played important roles in this reaction: Titanium(IV) isopropoxide and molecular iodine accelerated the transformation of the intermediate imine to the tetrahydroisoquinoline product; p‐toluenesulfonic acid contributed to the stereocontrol.

AbstractBiochemical studies of cellular processes involving polyubiquitin have gained increasing attention. More tools are needed to identify ubiquitin (Ub)‐binding proteins. We report diazirine‐based photoaffinity probes that can capture Ub‐binding proteins in cell lysates, and show that diazirines are preferable to aryl azides as the photo‐crosslinking group, since they decrease non‐selective capture. Photoaffinity probes containing at least two Ub units were required to effectively capture Ub‐binding proteins. Different capture selectivity was observed for probes containing diubiquitin moieties with different types of linkages, thus indicating the potential to develop linkage‐dependent probes for selectively profiling Ub‐binding proteins under various cellular conditions.
Supramolecular Vesicles Coassembled from Disulfide‐Linked Benzimidazolium Amphiphiles and Carboxylate‐Substituted Pillar[6]arenes that Are Responsive to Five Stimuli

Published: February 2017

AbstractNovel supramolecular vesicles based on host–guest systems were coassembled from carboxylate‐substituted pillar[6]arene (CPA[6]) and disulfide‐linked benzimidazolium amphiphiles, and the microstructures of the CPA‐based supramolecular vesicles were clearly elaborated. The supramolecular vesicles showed controlled drug release in response to five stimuli, with glutathione, pH, CO2, Zn2+ ions, and hexanediamine, leading to cleavage of the disulfide bonds, protonation of the carboxylate groups, metal chelation, and competitive binding. This is the first case of a smart pillararene‐based supramolecular vesicle being integrated with five stimuli‐responsive functions to meet the diverse requirements of controlled drug release. Importantly, each of the five stimuli is closely related to microenvironments of tumors and diseases of the human body. The smart stimuli‐responsive supramolecular vesicles have promising applications in drug therapy of tumors and relevant diseases.
