Shape optimization for the eigenfrequency of the plate
Authors: Gasimov Yusif S. , Allahverdiyeva Natavan A.
Published: February 2017

In this paper, we consider an eigenvalue problem for the biharmonic operator that describes the transverse vibrations of the plate.
Under the imposed boundary conditions, the eigenvalues of this operator are indeed eigenfrequencies of the clamped plate.
The domain of the plate is taken variable and the domain functional, involving an eigenfrequency, is studied.
A new formula for an eigenfrequency is proved, the first variation of the functional with respect to the domain is calculated, and the necessary condition for an optimal shape is derived. New explicit formulas are obtained for the eigenfrequency in the optimal domain in some particular cases.
Introduction: understanding language management and multilingualism in Malaysia
Authors: Zhou Minglang , Xiaomei Wang
Published: February 2017

This article introduces multilingualism in Malaysia and examines how the language management of the multilingual society there is challenged by interactions among global, regional, national, and local language orders. These orders and their interactions give rise to various language ideologies, which are struggling to maintain a hierarchy of their respective choice. From this perspective, this introductory article reviews the seven contributions in this issue and analyzes the impact of conflicting language ideologies on language policies, use, maintenance and development in families and communities in Malaysia. The analysis suggests that in Malaysia global and regional language orders have significantly influenced the national and local language orders while the national order has a relatively weak impact on the local language order. Malaysia’s diverse and sometimes conflicting language ideologies reflect the existing language orders and support them. The combination of the existing language orders and ideologies seems to be a perfect fit for unity in diversity regarding nation-building, but it is not necessarily a fit for diversity in unity in Malaysia. The lesson from the Malaysian experience is that language management and nation-building have to take full consideration of the interaction among global, regional, and national language orders within the communities involved.
Indigenous language development in East Malaysia
Authors: Smith James A. , Smith Karla J.
Published: February 2017

Many of the 138 living languages in Malaysia are listed as endangered and some listed as vigorous are undergoing language shift. Most of these languages are shifting towards Malay, the national language, and to English, an international language. Since standard Malay is the language of instruction in the government schools, many indigenous parents are speaking Malay to their children with the hope of giving them a better start in school. People in a number of the indigenous minority groups in Sabah and Sarawak recognize that language shift is occurring and are taking steps to reverse it. In the past 15 years several of the indigenous minority groups have been engaged in language development projects and, as awareness grows, more groups are joining them. They have developed appropriate writing systems and produced linguistic papers to increase understanding of the vocabulary and grammar of their languages. They have also implemented early childhood education programmes with the intention of increasing the number of speakers of the languages, and raising their status. This article presents some of the methods, activities, successes and challenges that these groups have experienced in their language development projects while seeking to revitalize their vulnerable languages.

Evaluation of ammonium bifluoride fusion for rapid dissolution in post-detonation nuclear forensic analysis
Authors: Hubley Nicholas T. , Brockman John D. , Robertson J. David
Published: February 2017

Dissolution of geological reference materials by fusion with ammonium bifluoride, NH4HF2 or ABF, was evaluated for its potential use in post-detonation nuclear forensics. The fusion procedure was optimized such that the total dissolution time was <3 h without compromising recovery. Geological reference materials containing various levels of silicates were dissolved and measured by ICP-MS to quantify elemental recovery. Dissolutions of NIST 278 obsidian and urban canyon matrix were performed with radiotracer spikes to measure potential loss of volatile elements during the fusion procedure via gamma-ray spectroscopy. Elemental percent recoveries obtained by ICP-MS were found to be 80–120% while recoveries of radiotracers were observed to be 90–100% with the exception of iodine.
Wann erleben Beschäftigte ihre Arbeit als sinnvoll? Befunde aus einer Untersuchung über professionelle Dienstleistungsarbeit
Authors: Hardering Friedericke
Published: February 2017

Der Beitrag knüpft an die aktuelle Diskussion über das Sinnerleben in professionellen Dienstleistungstätigkeiten an und beleuchtet die bisher weitgehend unberücksichtigte Frage nach der subjektiven Erlebensqualität sinnvoller Arbeit. Gegenstand sind die subjektiven Erfahrungen des Sinnerlebens sowie dessen Einschränkungen, die auf Basis von Interviews mit ÄrztInnen und SozialarbeiterInnen rekonstruiert werden. Der Beitrag zeigt, dass sich die Erfahrung von Sinnhaftigkeit wesentlich aus dem Gefühl von Kongruenz, der wahrgenommenen Übereinstimmung unterschiedlicher Nutzenperspektiven im Sinne eines Nutzens für den Einzelnen sowie für Andere ergibt. Zudem lassen sich neuartige Bedrohungen des Sinnerlebens identifizieren, die aus dem Verlust positiver Erfahrungsräume in der Arbeit sowie einer Reflexivierung von Sinnfragen resultieren.
Bioenergetic strategy of microalgae for the biodegradation of tyrosol and hydroxytyrosol
Authors: Papazi Aikaterini , Ioannou Andreas , Symeonidi Myrto , Doulis Andreas G. , Kotzabasis Kiriakos
Published: February 2017

Olive mill wastewater has significant polluting properties due to its high phenolic content [mainly tyrosol (trs) and hydroxytyrosol (htrs)]. Growth kinetics and a series of fluorescence induction measurements forScenedesmus obliquuscultures showed that microalgae can be tolerant of these phenolic compounds. Changes in the cellular energy reserves and concentration of the phenolic compounds adjust the “toxicity” of these compounds to the microalgae and are, therefore, the main parameters that affect biodegradation. Autotrophic growth conditions of microalgae and high concentrations of trs or htrs induce higher biodegradation compared with mixotrophic conditions and lower phenolic concentrations. When microalgae face trs and htrs simultaneously, biodegradation begins from htrs, the more energetically demanding compound. All these lead to the conviction that microalgae have a “rational” management of cellular energy balance. Low toxicity levels lead to higher growth and lower biodegradation, whereas higher toxicity levels lead to lower growth and higher biodegradation. The selection of appropriate conditions (compatible to the bioenergetic strategies of microalgae) seems to be the key for a successful biodegradation of a series of toxic compounds, thus paving the way for future biotechnological applications for solving complicated pollution problems, like the detoxification of olive mill wastewater.
Schema activation through pre-reading activities: teaching proverbs in L2
Authors: Salbego Nayara , Osborne Denise M.
Published: February 2017

Although educators are aware that the use of pre-reading activities can prompt schemata and therefore enhance the reading process in a foreign language (e.g., Aebersold; Field, 2007; Johnson, 1982; Langer, 1981), planning an effective pre-reading activity may pose a challenge. In this article, we discuss how students’ schemata on proverbs can be activated through pre-reading activities by promoting text structure awareness (e.g., Grabe; Stoller, 2011) and exploring cultural aspects embedded in proverbs in their first(s) language(s). This study proposes a pre-reading activity for the teaching of proverbs in a Portuguese as a foreign language class in a multilingual context, in which minimal interference from the teacher is required and dialogical interaction among students is promoted. The activity was applied in an intermediate class of Portuguese learners in an American university. The pre-reading activity was designed in order to help students establish a well-grounded basis before they encounter proverbs in Portuguese, from both formal and content perspectives. This study also analyzes the students’ feedback, collected in an online survey. The analysis shows an overwhelmingly positive response to the pre-reading activity.
Repensando o ensino da compreensão oral em turmas heterogêneas de língua-cultura estrangeira
Authors: Cunha José Carlos Chaves da , Santos Edirnelis Moraes dos
Published: February 2017

Based on the data of GEALC (Research Group Teaching and Learning of Languages and Cultures), we are interested in teaching oral comprehension (OC) in foreign language (FL) or second language (L2) in heterogeneous classes under the linguistic and cultural perspective. OC is indeed one of the most neglected general competences in teachers’ training, the most difficult to be acquired and the most present in people’s life. Based on the Lhote’s “landscape” model of OC (1995, 2001), Conseil of Europe’s action-oriented approach (2001) and ethnographic methodology, we describe and analyze the oral records and OC activities taken place in PFL (Portuguese as a foreign language) classes of UFPA. We noticed the material mainly consists of records of activities proposed and adopted by the course’s pedagogical kit (music, audiovisual resources produced by proficiency exam). The OC activities (“identical to the real” life and“pedagogically communicative”) are clearly driven by action-oriented approach, but Lhote’s model is still not or rarely applied in the preparation of activities, which could result in a more attentive listening capacity.

Published: February 2017

El objetivo de este trabajo fue determinar el efecto de sistemas de labranza y densidades de siembra en la calidad de las raíces tuberosas de batata (Ipomoea batata (L) Lamb.). El estudio se realizó en la Universidad Central de Venezuela, en el año 2014. Se determinaron los grados de severidad de la degradación del suelo y su correspondencia con las escalas de preferencia basadas en el peso unitario y dimensiones de la raíz tuberosa. Se usó un arreglo en franjas, donde los sistemas de labranza (SL) fueron asignados a las parcelas, y las densidades de siembra (Ds) a las franjas. Los SL consistieron en labranza vertical con cincel (LC), con arado de disco (LA), convencional con tres pases de rastra de disco (LCo) y mínima con un pase de rastra de disco (LM). Las Ds fueron de 0,25 cm (D1) y 0,15 cm (D2) en la hilera. La calidad física del suelo fue superior en los tratamientos de LA. De estos, la combinación con la distancia de siembra más larga (LA-D1) favoreció la mayor calidad postcosecha del cultivo. Al contrario, en los tratamientos con cincel se promovió la menor aceptación del consumidor. La ligera a moderada severidad de la degradación del suelo no explicó la variación de la calidad postcosecha. Se in ere sobre la menor tasa de movimiento de agua en LC, que promovió un exceso de humedad y la más baja calidad de la raíz tuberosa.

Abstract:

Introduction: Violence against health care providers is getting more awareness nowadays. This topic is in the focus of international scientific attention also, although in Hungary exact data is lacking. Aim: The present study aimed to assess the correlations between violent acts against health care workers and their effects with different sociodemographic and workplace-related factors. Method: A quantitative cross-sectional online survey was conducted enrolling 1201 health care providers. Data were analysed trough chi-square, Kolmogorov–Smirnov, Mann–Whitney and Kruskal–Wallis tests, where appropriate. Results: Verbal and physical aggression was experienced more frequently by nurses who were males, above the age of fifty, working in in-patient care or in 12 hours shifts or constant night shifts. The same groups of health care providers suffered more from the negative emotional consequences of violent acts. Conclusions: Aggression is a serious problem in the Hungarian health care system, therefore employees have to be prepared for these acts. Orv. Hetil., 2017, 158(6), 229–237.

Stabilising railway embankments using an integrated tied back-to-back strengthening system
Authors: Esmaeili Morteza , Arbabi Behnam
Published: February 2017

This study investigates the role of an integrated tied back-to-back strengthening system in increasing the failure load and decreasing the crest settlement of railway embankments. The strengthening system consists of bars or tendons installed through the embankment and tied together with continuous plates on each side. Numerous three-dimensional numerical finite-element models of railway embankments with and without the strengthening system were analysed to obtain the optimum level for installation of the system and the mechanical specifications required to satisfy embankment stability requirements. Six 10 m-high embankments with 1:1 side-slopes, three with the strengthening system and three without, were constructed at a 1:20 scale in a loading chamber and uniformly loaded on the crest. The results revealed that the unstrengthened embankments failed under an average stress level of 123 kN/m2 with an average crest settlement of 38·5 mm. The strengthened embankments failed under an average stress level of 186·67 kN/m2 with a crest settlement of 29·0 mm, representing a 51% increase in failure stress and a 25% decrease in crest settlement.
Grinding point-temperature model of Elid oxide film and its heat transfer and formation mechanism of α-Fe2O3
Authors: Kuai Jicai
Published: February 2017

This paper studies the temperature of the grinding point of an oxide film and establishes a temperature model. The calculation results indicate that the temperature of the grinding point of a single abrasive grain is much higher than that of the grinding zone of the grinding wheel. Based on the analysis of the point-temperature model, the formation mechanism of the composite abrasive grains in an electrolytic in-process dressing (Elid) grinding oxide film is further clarified – that is, under the effect of the high temperature of the grinding point of the abrasive grains, the hydrous ferric oxide (Fe2O3) in the oxide film surrounding the abrasive grains is dehydrated and converted into α-ferric oxide, thus forming the grinding composite abrasive grains centered on grains and surrounded by α-ferric oxide. The results reveal the root causes why an Elid grinding oxide film has a polishing effect, which enriches the Elid grinding technology theory and has extremely important theoretical and practical significance.

Looking into the patriarchal world of Roald Dahl's short story "Taste" through and beyond its narrator
Authors: De Juan Luis
Published: February 2017

This article reflects on the presence of narrators in Roald Dahl’s short stories for adults, especially those in which the account is carried out by one of the characters. After underlining a number of features common to these narratives, it’s my aim to analyse the presence of the narrator in one of his most well-known short stories, “Taste”, and my main contention is that a careful consideration of this presence enriches the reading of the story. Even though the narration is carried out by a secondary character, whose role in the development of events might be minimum, his participation as narrator/commentator of the events allows to address both gender and class issues; furthermore, John Berger’s concept of gaze becomes a very useful element with which to uncover the narrator’s sympathies with a society ruled by patriarchal and classist parameters.
Protección constitucional del derecho a la inviolabilidad del domicilio en el ámbito castrense
Authors: García Martínez Gema
Published: February 2017

La especialidad de las misiones que constitucionalmente le han sido encomendadas a las Fuerzas Armadas y a sus miembros, así como la singularidad de los destinos del personal militar, con frecuentes cambios de localidad de manera forzosa, hacen que, de manera habitual, se vean obligados a residir fuera de su domicilio familiar. Es por este motivo, por el que en numerosas ocasiones los militares desarrollan su privacidad bien en cuartos habilitados en las propias unidades, centros u organismos militares, en residencias militares gestionadas por directores con empleo militar y dependientes del Ministerio de Defensa  o en períodos de ejercicios, maniobras o misiones, dentro o fuera del territorio nacional, en tiendas de campaña, barracones, o buques. De esta manera, podemos observar, como se amplían considerablemente los lugares en los que los miembros de esta institución, desarrollan su vida privada, lo cual a su vez, genera problemas de determinación en torno a cuáles de estos lugares pueden incluirse en el concepto de domicilio constitucionalmente merecedor de protección, especialmente a los efectos de la realización de entradas y registros.
Diferentes modelos de la función consultiva y jurisdiccional de la institución del Consejo de Estado: Francia, Bélgica, Portugal y Colombia
Authors: Triguero Ortiz Orlando
Published: February 2017

En este artículo, se describen las características del Consejo de Estado desde una perspectiva comparada. En algunos países dispone de una función de asesoramiento y en otros países tiene una función judicial como un tribunal administrativo supremo.Primeramente se estudia el Consejo de Estado francés y los Consejos de Estado con competencias similares, entre otros, el Consejo de Estado de Bélgica y el Consejo de Estado colombiano (como uno de los países de América Latina inspirado en la tradición jurídica europea), los cuales tienen un Consejo de Estado con una doble función, consultiva y judicial. Estos Consejos tienen generalmente el papel de asesor del gobierno y de ser la más alta jurisdicción de la rama administrativa.Seguidamente se estudia el Consejo de Estado portugués, que sólo dispone de una función de asesoramiento, de conformidad con la Constitución portuguesa. El Consejo de Estado portugués asesora al Presidente de la República en el ejercicio de la mayor parte de sus poderes de reserva.
Diritti costituzionali e crisi finanziaria: la rigidità costituzionale alla prova
Authors: Nocito Walter
Published: February 2017

En este trabajo nos proponemos de analizar la protección de los derechos sociales fundamentales así como las restricciones financieras, desde la perspectiva de la rigidez constitucional, de la resi-liencia y de la recistencia en el "nucleo duro" de los derechos fundamentales en un Estado social de de-recho. El análisis se centra en el dilema de la justicia constitucional en tiempos de crisis, y pone de ma-nifiesto los riesgos de la sobreexposición política para los Tribunales Constitucionales. Finalmente, en el trabajo se analiza el problema de la defición política de las priopridades relativas a los derechos funda-mentales en comparación con la teoría del constitucionalismo normativo y garantista.
Pharmacological Approaches and Natural Products for Prevention of Chemotherapy-Induced Peripheral Neuropathy - A Review
Authors: Cascella Marco , Muzio Maria Rosaria
Published: February 2017

Chemotherapy-induced peripheral neuropathy (CIPN) is a one of the most common and severe cancer treatment-related adverse effect. It can often cause the stop of the treatment and affects the long-term quality of life of cancer survivors, too. Unfortunately, there are no effective agent or protocol to prevent with strong evidence of effectiveness this toxicity prevention of CIPN. Thus, CIPN prevention mainly consists of cumulative dose-reduction or lower dose-intensities, especially in higher risk patients. After a brief description of pathophysiology and features of CIPN, the purpose of this study is to analyse the role of standard pharmacological approaches and natural products for prevention of this serious side effect.

A case vignette is provided to illustrate the approach. The intent is to provide undergraduate social work students and educators with grounding in a resiliency-oriented framework useful in assessment and practice with military service personnel to facilitate healthy coping and adaptation to civilian life.
Learning Strategies and Mutual Aid Groups in BSW Education
Authors: Trull Laura , Myers Karen
Published: February 2017

Drawing from cooperative learning strategies and the mutual aid model as theoretical foundations, a creative design for teaching group work practice skills to baccalaureate level social work students is presented. Students in a senior-level group work course facilitate a series of six group sessions structured around a course reading with sophomore-level Introduction to Social Work students. Multiple benefits were initially reported including skill acquisition, mentorship, and a sense of increased competence. This design is promising, and social work educators are encouraged to replicate different versions and interpretations of it for further experience and increased quantitative evaluation.

Published: February 2017

AbstractMedical educators are recognizing that social accountability is a tenet of Canadian medical education, yet it is a difficult concept to teach didactically. Accumulating evidence supports the integration of social accountability into the medical curriculum through community involvement. Fortunately, the University of British Columbia Faculty of Medicine enables students to pursue community learning as part of its curriculum; and we, five medical students, benefited from that opportunity. This commentary will promote the importance of teaching social accountability in medical schools through community-based learning based on available literature and our personal experience with Vancouver’s Downtown Eastside (DTES). RésuméLes professeurs de médecine reconnaissent que la responsabilité sociale est un pilier de l’éducation médicale canadienne; néan- moins, c’est un concept difficile à enseigner didactiquement. De plus en plus de preuves appuient l’intégration de la responsabilité sociale au curriculum médical à travers l’engagement communautaire. Heureusement, la Faculté de Médecine de l’Université de la Colombie-Britannique permet aux étudiants de participer à l’apprentissage par engagement communautaire en tant que composante du curriculum; nous, cinq étudiants en médecine, avons pu profiter de cette opportunité.

Published: February 2017

Background: Mimosa pudica is a traditionally used folk medicine to treat various disorders like infections, anxiety, depression, bleeding disorders, convulsions, rheumatoid arthritis, muscular pain, asthma, snake bite etc. We evaluated the anti-inflammatory activity of hydroalcoholic extract of Mimosa pudica whole plant (HAEMPWP) in rats.Methods: HAEMPWP was prepared using Soxhlets apparatus. Acute toxicity tests were done with HAEMPWP given orally to albino rats in increasing doses up to 3200 mg/ kg body weight. The anti-inflammatory action was evaluated by Carrageenan induced paw edema method. Thirty albino rats were grouped into five groups and each contained six rats. Group I (control group) received distilled water orally. Group II (standard) received Aspirin orally dissolved in distilled water. Groups III, IV and V received HAEMPWP in doses of 200 mg/kg, 400 mg/kg and 800mg/kg orally dissolved in distilled water. Data analysis was done by one way ANOVA and unpaired t test using SPSS 16 for windows.Results: HAEMPWP showed a significant anti-inflammatory activity as compared to control. There was no statistically significant dose dependent increase in the anti-inflammatory activity.Conclusions: HAEMPWP possesses significant anti-inflammatory activity and could be an effective treatment option for various inflammatory conditions.

Background: Infertility leads to considerable personal suffering and disruption of family life. According to United Nations "Reproductive health is a state of complete physical mental and social well-being and not merely the absence of disease or infirmity in all matters relating to the reproductive system and to its functions and processes". The objective of present study was to find out different causes of female infertility with diagnostic laparoscopy and their comparative frequency in primary and secondary infertility.Methods: It is a prospective study conducted on all infertile women and they underwent diagnostic laparoscopy for primary and secondary infertility during the study period. Couples who had not lived together for at least 12 months, and those with male factor infertility were excluded. Data were collected on a proforma, and analyzed on SPSS package for windows version 10. Frequencies were calculated for laparoscopic findings regarding primary and secondary infertility.Results: Fifty infertile women underwent laparoscopy during the study period, 35 (70%) had primary infertility while 15 (30%) secondary infertility. 10 (28.5%) patients with primary and 3 (20%) patients with secondary infertility had no visible abnormality. The common finding was tubal blockage in 10 (28.5%) and 5 (33.3%) cases of primary and secondary infertility respectively. 9 (25.7%) cases of primary infertility were detected as polycystic ovaries (PCO) and 2 (13.3%) in cases of secondary infertility. Endometriosis was found in 1 case with primary infertility and 2 (13.3%) cases with secondary infertility. Fibroid was found in 3 (8.57%) and 1 (6.6%) cases of primary and secondary infertility respectively.Conclusions: Most common causes responsible for infertility were tubal occlusion and polycystic ovary. Infertile couple should be thoroughly investigated. Laparoscopy in infertility can be used for a definitive diagnosis.

Published: February 2017

Background: Intestinal perforation as a complication of enteric fever is still a serious problem in developing nations. Enteric ileal perforation is associated with high morbidity and mortality and many patients present in a severe toxic state because of delay in diagnosis and late presentation to hospital.Methods: A prospective study was conducted to assess the prognostic factors in enteric ileal perforation. Observations were made regarding symptoms, signs, duration of illness and presentation of patients to the hospital after acute episode. Per operative findings regarding site, size and number of perforations were recorded. Operative procedures were simple closure, ileostomy, or resection of diseased segment including right hemicolectomy done for associated caecal perforation and entero enteric anastomosis. Post-operative complications like wound infection, wound dehiscence, residual abscess, faecal fistula and deaths were documented.Results: There were 50 enteric ileal perforation cases with a age range of 13-80 with a mean age of 30.7. Male: female ratio was 11: 1. 85% of patients presented within 48 hrs of onset of symptoms of perforation and there is significant mortality in patients who presented more than 48 hrs of onset of symptoms of perforation (57.14%). Mortality was high in multiple perforation group (40%) and also higher incidences of fecal fistula and wound dehiscence.Conclusions: Age and sex have no bearing on the outcome. Perforation presentation interval, delay in surgery, number of perforations are important prognostic markers for typhoid ileal perforation.
