Published: August 2018

Introduction Patients with large ptotic breasts undergoing immediate implant-based reconstruction often require skin-reducing mastectomy to optimise the aesthetic outcome. However, healing complications, especially at the resulting inverted T-junction, leading to wound dehiscence, infection, skin necrosis, implant exposure and failed reconstruction have been widely reported. We present an innovative approach for immediate implant-based reconstruction combining porcine- or bovine-derived acellular dermal matrices with a de-epithelialised dermal sling to protect and support the implant, while improving clinical outcomes in this challenging group of patients. Materials and methods Demographic, tumour and surgical data were reviewed for patients undergoing Wise pattern (T-scar) skin-reducing mastectomies with immediate implant-based reconstruction combining porcine- or bovine-derived acellular dermal matrices with a de-epithelialised dermal sling. Results This technique was successfully employed to reconstruct five large pendulous breasts in four breast cancer patients with a median age of 50.5 years (range 34–61 years) who were not suitable for, or had declined, flap-based reconstruction. The acellular dermal matrices used were SurgiMend®, StratticeTM and Braxon® and the expandable implants were placed in the sub-pectoral (n = 3) and pre-pectoral (n = 1) planes. The technical steps and clinical outcomes are presented. One patient experienced T-junction breakdown overlying the de-epithelialised dermis without implant loss. Conclusion The combination of an acellular dermal matrix and a dermal sling provides a double-layer ‘water-proofing’ and support for the implants inferiorly, avoiding T-junction breakdown complications, since any dehiscence is on to well-vascularised dermis. Furthermore, the acellular dermal matrix stabilises the implant in the large mastectomy cavity (pocket control). This approach provides a viable option which facilitates mastectomy and immediate implant reconstruction in large-breasted patients.
A rare complication of ileostomy obstruction: Boerhaave syndrome
Authors: Yap D , Ng M , Mbakada N 
Published: August 2018

Small bowel obstruction is the most common surgical emergency after a patient has had abdominal surgery. However, Boerhaave syndrome secondary to an ileostomy obstruction has not been reported in current literature. We present a rare case of two concurrent surgical emergencies in a patient with Boerhaave syndrome and small bowel obstruction. A 38-year-old woman presented with sudden onset severe central chest pain associated with breathlessness. She had a history of Crohn’s disease, which had been treated with pancolectomy and ileostomy. Clinical examination showed an extensive palpable surgical emphysema extending from the neck to the pelvis with a distended abdomen. Computed tomography contrast of the chest and abdomen reported bilateral pneumothoraces, ruptured oesophagus and distended small bowel secondary to obstruction at the ileostomy. She was referred to the nearest cardiothoracic centre for an urgent assessment. Unfortunately she passed away shortly after the scan. Ruptured oesophagus is associated with a high mobidity and mortality if it is not recognised, so early diagnosis and prompt treatment is crucial in reducing the mortality rate. There is a strong association between stoma formation and incidence of small bowel obstruction but no difference between an ileostomy and colostomy. This case helps to illustrate the challenging management of chronic recurring abdominal obstruction and the delicate balance of risk of complication versus benefit of various management being surgical or conservative. All general surgeons should be wary of the potential complication of oesophageal perforation secondary to intestinal obstruction.
‘Smart, clued-in guys’: Irish rugby players as sporting celebrities in post-Celtic Tiger Irish media
Authors: Free Marcus 
Published: August 2018

Abstract
Ireland’s ‘Celtic Tiger’ economic boom ended with the 2008 global financial crisis. There followed a series of severe ‘austerity’ budgets and public service pay deals involving cuts in public service provision and employment reform. These were accompanied by approving Irish media narratives of atonement for Celtic Tiger ‘excess’ and, more recently, of corresponding ‘recovery’ through collective and individual discipline and entrepreneurial endeavour. This article focuses on the interplay between Irish media narratives of austerity and recovery and constructions of gender, class and national identity in representations of rugby players as celebrities. It explores how elite players have been presented as exemplary of the neo-liberal management of physical and economic risk, and how the repeated focus on successful struggles with diet and injury and post-career educational and business investments highlights their optimizing of the physical and social capital afforded by celebrity status. The emphasis on discipline and ‘smart’ economic management chimes with the hegemonic political and media discourse of ‘no alternative’ government austerity, and with economic recovery through individual acceptance of responsibility.

Authors: Groth Stefan 
Published: August 2018

Zusammenfassung
Sprichwörter und Redewendungen dienen in multilateralen Verhandlungen und anderen politischen Kontexten der Verstärkung und Legitimierung von Aussagen. Als Anspielungsformeln eignen sie sich zur impliziten Kommunikation, bei der keine direkten Anschuldigungen oder Forderungen erhoben werden und die für viele politische Kontexte typisch sind. Der Beitrag beleuchtet unterschiedliche Funktionen von Sprichwörtern und Redewendungen als Teil von kommunikativen Strategien in multilateralen Verhandlungen und fragt nach kontextuellen Faktoren, die bei ihrer Analyse Berücksichtigung finden müssen.

Authors: Buduma Parusharamulu , Panda Gayadhar 
Published: August 2018

AbstractThis paper presents an output and state feedback robust LQR (OSRLQR ) optimal controller for the control of active (P) and reactive power (Q) in grid-connected mode, and voltage (V) and active power in islanded mode of photovoltaic (PV) distributed generation (DG) system. The OSRLQR scheme is comprising of an output and state feedback controllers, which are designed based on LMI-LQR optimization approach. The DG inverter along with proposed controller is configured to work as a current source in grid-connected mode and a voltage source in island mode using P-Q and P-V control scheme respectively. A seamless transition between the grid connected and island modes under the presence of the proposed controller is achieved using a passive island detection and synchronization algorithm along with load shedding. The entire control scheme of the DG system is modelled and analyzed using MATLAB/SIMULINK/Robust Tool-Box, and the practical feasibility of the proposed control scheme is verified using dSPACE. A superior trade-off robustness among the stability and performance is the final outcome of the DG system with proposed control scheme. Performance of the proposed control scheme is compared with conventional PI controller and the comparative results indicate the superior performance of proposed control scheme over the conventional control scheme.

Abstract
Brooks, ER, Benson, AC, and Bruce, LM. Novel technologies found to be valid and reliable for the measurement of vertical jump height with jump-and-reach testing. J Strength Cond Res 32(10): 2838–2845, 2018—Vertical jump testing is used by coaches and athletes across many sports and disciplines to assess lower-body power and neuromuscular fatigue. A range of devices are available to measure jump height, with recent innovations attempting to improve portability, usability, and accessibility. New devices should be evaluated for their effectiveness and dependability in specific tests before being adopted. The purpose of this study was to assess the validity and reliability of 2 novel measurement devices for jump height testing with a jump-and-reach protocol. Twenty-six healthy, active adults participated during 2 testing occasions. A wearable inertial measurement unit (VERT) and a smart device application (My Jump 2) were compared with established measures (force platform and jump-and-reach apparatus [Yardstick]). Correlations between the VERT and force platform were r = 0.95 (90% confidence interval [CI]: 0.93–0.97), and r = 0.93 (90% CI: 0.90–0.95) for the Yardstick. Correlations between the My Jump 2 app and force platform were r = 0.98 (90% CI: 0.97–0.99), and r = 0.94 (90% CI: 0.92–0.96) for the Yardstick. Reliability, measured as intraclass correlation coefficient (ICC), was 0.91 (90% CI: 0.87–0.94) for the VERT, and 0.97 (90% CI: 0.96–0.98) for the My Jump 2 app. Intrarater reliability for the My Jump 2 app was ICC = 0.99 (90% CI: 0.99–0.99). The VERT and the My Jump 2 app have both shown acceptable validity and reliability compared with both the force platform and Yardstick. However, practitioners should consider which measurement device/s to use based on the acceptable level of potential error for their population and testing objectives.

Numerical Study of Plasticity Effects on High Residual Stress Measurement Using Ring-Core Technique
Authors: Moharrami R. , Sadri M. 
Published: August 2018

Abstract
The ring-core technique is a stress relaxation-based method that is used to determine surface residual stresses in a material based on the linear elastic theory. However, material yielding that is due to ring creation on a highly stressed body would cause some errors. In this article, plasticity effects on high-level uniform residual stresses calculated by the ring-core technique were examined via a numerical analysis. The plasticity error owing to yielding was obtained by comparing the applied stress and the calculated stress derived from finite element (FE) simulation. Moreover, using the prepared FE model, the effects of various parameters, such as state of loading, ring geometry, and tangent modulus, were investigated. The results showed a maximum 30 % positive errors in the calculated residual stresses and the great impact of ring geometry on the plasticity error. Based on the results, the optimized ring diameter and depth for suitable precision were proposed.
Jet Cavitation Erosion in Chamfered and Tapered Cylindrical Passages: Comparison with Visualization and Simulation
Authors: Kazama Toshiharu , Noda Tatsuya 
Published: August 2018

Abstract
In hydraulic equipment, a jet cavitation occurs frequently at points wherein oil flows through an orifice and a gap that is due to a high pressure and large pressure difference. These jets typically erode equipment surfaces when the cavitation bubbles collapse. Although the erosion characteristics have been studied for cases wherein jets impinge on surfaces at normal or oblique angles, cavitation erosion has not been studied in cases wherein jets flow parallel to the wall surfaces. This study uses the method outlined in ASTM G134-17, Standard Test Method for Erosion of Solid Materials by Cavitating Liquid Jet, to perform 8-hour-long erosion tests on aluminum specimens and to visualize cavitation jets in transparent acrylic specimens. We test specimens with chamfers and tapers in different orientations and compare the results with numerical simulations to better understand the mechanisms behind cavitation erosion. The inner walls of the chamfered specimens were partially eroded near the downstream chamfered edge, regardless of the chamfer location. During the testing time, the chamfered surfaces and outer surfaces on both ends were not eroded. Erosion pits were visible locally along the convergent and straight paths in the tapered specimen, but the pits did not appear in the divergent-tapered specimen. Visualization and numerical results offer some insights into the pressure dynamics that explain why divergent tapers seem to be effective countermeasures against cavitation erosion in hydraulic equipment.
Cavitating Flow Luminescence as a Potential Source for Analytical Spectroscopy
Authors: Whitfield Claire M. F. , Foulkes Michael E. , Hywel Evans E. 
Published: August 2018

Abstract
Cavitating flow luminescence (CFL) has been observed for the first time at the microscale in fluid flow through a Venturi orifice. Water and mixtures of dimethyl sulfoxide and water were pumped through a Venturi orifice with a 220-μm inside diameter at flow rates between 60–100 mL min−1 to generate cavitation bubbles downstream of the Venturi restriction. Cavitation inception was observed to occur at a flow rate of 35 mL min−1 and a cavitation inception number of σi ≈ 0.83. The onset of CFL emission occurred at a flow rate of 60 mL min−1 and increased with increasing flow rate through the orifice. CFL also increased with decreasing temperature and decreasing vapor pressure of the cavitating fluid. The intensity of CFL also increased when argon was present as a dissolved gas compared to untreated fluids.
Cancer risk assessment for occupational exposure to chromium and nickel in welding fumes from pipeline construction, pressure container manufacturing, and shipyard building in Taiwan

Published: August 2018

Abstract

Objective
We assessed the cancer risks resulting from the exposure to chromium, hexavalent chromium (Cr (VI)), oxidic nickel (Ni), and soluble Ni in welding fumes during pipeline and shipyard construction and pressure container manufacturing in Taiwan. We also determined the roles of welding performance and demographic characteristics during the exposure to Cr and Ni.

Methods
Personal air samples were collected for the analysis of Cr and Ni, and the concentrations of Cr (VI), oxidic Ni, and soluble Ni were quantified. We assessed cancer slope factors for Cr, Cr (VI), oxidic Ni, and soluble Ni, and we used the Incremental Lifetime Cancer Risk model proposed by the United States Environmental Protection Agency to calculate excess risk.

Results
The risks of exposure to Cr and Cr (VI) in welding fumes exceeded the acceptable level of occupational exposure (10-3). We ranked the excess cancer risk in three industries in decreasing order as follows: pipeline construction, shipyard construction, and pressure container manufacturing. The most sensitive parameters for the risk assessment were Cr and Ni concentrations. Statistically significant determinants of Cr (VI), oxidic Ni, and soluble Ni concentrations were the following : stainless steel as the base metal and the filler metals of shielded metal arc welding (SMAW) and of gas tungsten arc welding (GTAW).

Conclusion
The study revealed that welders belong to a high cancer-risk group. Furthermore, we demonstrated the roles of filler metals and stainless steel in exposure to Cr and Ni.

Published: August 2018

BACKGROUND:
Recruiting and retaining community-based pediatricians for teaching medical students has been explored through the lens of preceptors and educational leaders. The purpose of this study was to explore the perspective of pediatric department chairs, a key stakeholder group charged with maintaining teaching capacity among a faculty.

METHODS:
In 2015, members of the Association of Medical School Pediatric Department Chairs and Council on Medical Student Education in Pediatrics joint task force disseminated a 20-item survey to pediatric department chairs in the United States and Canada. Topics included demographics, incentives offered to community pediatricians, and the perceived value and feasibility of such incentives. Data were analyzed using descriptive statistics and χ2 to compare categorical variables.

RESULTS:
Pediatric department chairs from 92 of 145 (63% response rate) medical schools returned the survey. Sixty-seven percent reported difficulty recruiting or retaining preceptors, and 51% reported high-reliance on preceptors for the ambulatory portion of the pediatrics clerkship. Almost all (92%) cited competition from other programs for the services of community preceptors. The provision of incentives was correlated with perceived feasibility (R2 = 0.65) but not their perceived value (R2 = 0.12). Few (21%) chairs reported providing financial compensation to preceptors. The provision of compensation was not related to reliance but did vary significantly by geographical region (P &lt; .001).

CONCLUSIONS:
Pediatric departments rely heavily on community-based pediatricians but face competition from internal and external training programs. The perspective of department chairs is valuable in weighing interventions to facilitate continued recruitment and retention of community preceptors.

El derecho administrativo colombiano esta impregnado con un fuerte barniz de jurisdiccion rogada, si bien de suma importancia en el desarrollo de muchos temas, presenta grandes contradicciones en el derecho administrativo desde el derecho constitucional colombiano. Veeremos las fuentes historicas interpretativas en la que se ha desarrollado la dialectica que se presenta entre el estado constitucional de derecho y la justicia rogada en el derecho administrativo colombiano, y como el debate entre paradigmas hermeneuticos como el Positivismo y Jusnaturalismo han sido la fuente fundamental de las apresiaciones juridicas el marco de la jurisdiccion rogada. Asi mismo, la influencia de las nuevas concepciones del derecho adminsitrativo desde una optica constitucional de la mano de principios como el iura novit curia ofrecen acercamientos hacia una justicia material efectiva en el derecho laboral administrativo.
