Authors: Gao Yubin , Shao Yanling
Published: December 2016

An $n\times n$ sign pattern ${\cal A}$ is said to be potentially nilpotent (PN) if there exists some nilpotent real matrix $B$ with sign pattern ${\cal A}$. In [M.~Arav, F.~Hall, Z.~Li, K.~Kaphle, and N.~Manzagol.Spectrally arbitrary tree sign patterns of order $4$, {\em Electronic Journal of Linear Algebra}, 20:180--197, 2010.], the authors gave some open questions, and one of them is the following: {\em For the class of $4 \times 4$ tridiagonal sign patterns, is PN (together with positive and negative diagonal entries) equivalent to being SAP?}\ In this paper, a positive answer for this question is given.

Aims

The aims of this study were to evaluate the clinical and radiological outcomes of the Universal-2 total wrist arthroplasty (TWA) in patients with rheumatoid arthritis.

Patients and Methods

This was a retrospective review of all 95 Universal-2 TWAs which were performed in our institution between 2003 to 2012 in patients with rheumatoid arthritis. A total of six patients were lost to follow-up and two died of unrelated causes. A total of ten patients had bilateral procedures. Accordingly, 75 patients (85 TWAs) were included in the study. There were 59 women and 16 men with a mean age of 59 years (26 to 86). The mean follow-up was 53 months (24 to 120). Clinical assessment involved recording pain on a visual analogue score, range of movement, grip strength, the Quick Disabilities of the Arm, Shoulder and Hand (DASH) and Wrightington wrist scores. Any adverse effects were documented with particular emphasis on residual pain, limitation of movement, infection, dislocation and the need for revision surgery. Radiographic assessment was performed pre-operatively and at three, six and 12 months post-operatively, and annually thereafter. Arthroplasties were assessed for distal row intercarpal fusion and loosening. Radiolucent zones around the components were documented according to a system developed at our institution.

Results

The mean worst pain was 8.1 (3 to 10) pre-operatively and 5.4 (0 to 10) at latest follow-up (p <  0.001). Movements were preserved with mean dorsiflexion of 29o (0 o to 70 o) and palmar flexion of 21o (0o to 50o). The mean grip strength was 4.8 kg (1.7 to 11.5) pre-operatively and 10 kg (0 to 28) at final follow-up (p < 0.001). The mean QuickDASH and Wrightington wrist scores improved from 61 (16 to 91) to 46 (0 to 89) and 7.9 (1.8 to 10) to 5.7 (0 to 7.8) (p <  0.001). A total of six patients (7%) had major complications; three required revision arthroplasty and three an arthrodesis. The Kaplan-Meier probability of survival using removal of the components as the endpoint was 91% at 7.8 years (95% confidence interval 84 to 91).

Conclusion

The Universal-2 TWA is recommended for use in patients with rheumatoid arthritis. Cite this article: Bone Joint J 2016;98-B:1642–7.
Is the hip capsule thicker in diseased hips?
Authors: Rakhra K. S. , Bonura A. A. , Nairn R. , Schweitzer M. E. , Kolanko N. M. , Beaule P. E.
Published: December 2016

Objectives

The purpose of this study was to compare the thickness of the hip capsule in patients with surgical hip disease, either with cam-femoroacetabular impingement (FAI) or non-FAI hip pathology, with that of asymptomatic control hips.

Methods

A total of 56 hips in 55 patients underwent a 3Tesla MRI of the hip. These included 40 patients with 41 hips with arthroscopically proven hip disease (16 with cam-FAI; nine men, seven women; mean age 39 years, 22 to 58) and 25 with non-FAI chondrolabral pathology (four men, 21 women; mean age 40 years, 18 to 63) as well as 15 asymptomatic volunteers, whose hips served as controls (ten men, five women; mean age 62 years, 33 to 77). The maximal capsule thickness was measured anteriorly and superiorly, and compared within and between the three groups with a gender subanalysis using student’s t-test. The correlation between alpha angle and capsule thickness was determined using Pearson’s correlation coefficient.

Results

Superiorly, the hip capsule was significantly greater in cam- (p = 0.028) and non-FAI (p = 0.048) surgical groups compared with the asymptomatic group. Within groups, the superior capsule thickness was significantly greater than the anterior in cam- (p < 0.001) and non-FAI (p < 0.001) surgical groups, but not in the control group. There was no significant correlation between the alpha angle and capsule thickness. There were no gender differences identified in the thickness of the hip capsule.

Conclusion

The thickness of the capsule does not differ between cam- and non-FAI diseased hips, and thus may not be specific for a particular aetiology of hip disease. The capsule is, however, thicker in diseased surgical hips compared with asymptomatic control hips. Cite this article: K. S. Rakhra, A. A. Bonura, R. Nairn, M. E. Schweitzer, N. M. Kolanko, P. E.

Rhetorik der Stadt
Authors: Smolarski Pierre
Published: December 2016

Die Rhetorik ist ohne die Stadt nicht zu denken. Die Stadt als der Ort verdichteten Austauschs - nicht nur von Waren und Dienstleistungen, sondern vor allem auch von Meinungen, Ansichten und Weltauffassungen, kurz: als ein Ort der Doxa - ist der prototypische Ort der Rhetorik. Anhand von Problemen der Orientierung und des Place-Making zeigt Pierre Smolarski die Stadt als Ort nicht nur der Verdichtung und des Wettstreits divergenter Meinungen, sondern auch als Gegenstand mannigfaltiger rhetorischer Bemühungen - sie ist nicht nur ein Raum für Rhetorik, sondern auch für sich ein rhetorischer Raum.

Authors: Grzechca Damian E. , Pelczar Piotr , Chruszczyk Lukas
Published: December 2016

This paper presents analysis of object location accuracy of a mobile device on the basis of the iBeacon technology. The research starts with radio signal strength indicator analysis along the corridor in order to create a path loss model for iBeacon. Two cases are taken into account: line of sight and non-line of sight for model creation. For both cases two tests: Chi-square, Shapiro-Wilk have been performed. It has also been checked if the HCI (Host Controller Interface) is a source with a memory. Acquired data have been filtered with different type of filters, e.g. median, moving average and then compared. Next, the authors evaluated the indoor positioning trilateration algorithms with the use of created model for exemplary hall. The RSSI map (radiomap) was created and the logarithm propagation model was designed. The logarithmic model estimated distance with average error 1.09m for 1 – 9m and 1.75m for 1-20m and after trilateration, the positions with average error 2.45m was achieved. A statistical analysis for acquiring data led to the final conclusion which enhanced knowledge about positioning based on the popular iBeacon technology.

Effects of Temperature and Strain Rate on Tensile Deformation Behavior of 9Cr-0.5Mo-1.8W-VNb Ferritic Heat-Resistant Steel
Authors: Guo Xiaofeng , Weng Xiaoxiang , Jiang Yong , Gong Jianming
Published: December 2016

A series of uniaxial tensile tests were carried out at different strain rate and different temperatures to investigate the effects of temperature and strain rate on tensile deformation behavior of P92 steel. In the temperature range of 30–700 °C, the variations of flow stress, average work-hardening rate, tensile strength and ductility with temperature all show three temperature regimes. At intermediate temperature, the material exhibited the serrated flow behavior, the peak in flow stress, the maximum in average work-hardening rate, and the abnormal variations in tensile strength and ductility indicates the occurrence of DSA, whereas the sharp decrease in flow stress, average work-hardening rate as well as strength values, and the remarkable increase in ductility values with increasing temperature from 450 to 700 °C imply that dynamic recovery plays a dominant role in this regime. Additionally, for the temperature ranging from 550 to 650 °C, a significant decrease in flow stress values is observed with decreasing in strain rate. This phenomenon suggests the strain rate has a strong influence on flow stress. Based on the experimental results above, an Arrhenius-type constitutive equation is proposed to predict the flow stress.
An Analysis of Factors Affecting Mature Age Students’ Academic Success in Undergraduate Nursing Programs: A Critical Literature Review
Authors: Hayden Lisa J. , Jeong Sarah Y. , Norton Carol A.
Published: December 2016

The population of mature age students entering university nursing programs has steadily increased in both Australia and worldwide. The objective of the literature review was to explore how mature age students perform academically and to analyse the factors associated with their academic performance in nursing programs. A literature search was conducted in the following databases: CINAHL, ProQuest, Medline, Cochrane, Mosby’s Index, Joanna Briggs Institute (JBI), and Scopus. Twenty-six (26) research papers published between 2000 and 2014 have met the selection criteria of this review. The key themes identified include; 1) ambiguity in definition of mature age and academic success, 2) age and academic success, 3) intrinsic factors (life experiences, emotional intelligence, and motivation and volition), and 4) extrinsic factors (peer, academic and family support; and learning style, components of the modules and mode of delivery). Current literature provides evidence that mature age nursing students perform at a higher level within the methodological issues discussed in this paper. Future research is warranted to advance the understanding of the complex relationship between extrinsic and intrinsic factors of mature age students and their academic success in higher education. Nursing educators will benefit from novel evidence, ideas and opportunities to explore and implement in nursing education.

This paper examines differences between formal safety and real safety in Estonian small and medium-sized enterprises. The results reveal key issues in safety culture assessment. Statistical analysis of safety culture questionnaires showed many organisations with an outstanding safety culture and positive safety attitudes. However, qualitative data indicated some important safety weaknesses and aspects that should be included in the process of evaluation of safety culture in organisations.
Job-Specific Factors and Prevalence of Multiple and Disabling Musculoskeletal Pain Among Office Workers, Nurses, and Caregivers in Estonia
Authors: Merisalu Eda , Animägi Liina , Oha Kristel , Freimann Tiina , Sirk Tuuli
Published: December 2016

The aims of this study were to describe job-specific factors and prevalence of musculoskeletal pains (MSPs) by the occupation and body regions in the past 12 months and past month, to analyse multisite and disabling pain and sick leave among office workers (OW), nurses and caregivers (CG); and to find relationships between the observed indicators. The study groups were selected by random sample method. Questionnaire responses on demographic parameters, job-specific factors, and MSPs by body parts in the past 12 months (MSP-12) and past month (MSP-1) were analysed. A questionnaire was sent to 1291 participants. The response rate was 54%. Most of the participants were women, with mean age 41.2 (±11.5) years, working on average 42.8 (±6.7) hours per week and had service length more than five years. Repetitive movements of wrist/hands and working under time pressure were more often reported risk factors by the nurses. Lifting weights 25 kg and more, climbing up and down, kneeling more than one hour a day and piecework finished in the work shift were the most often reported job-related risk factors for the CGs. Use of a keyboard was the same frequent work-related risk factor for the OWs. The most prevalent MSP-12 was low back pain for CGs (66.3%) and nurses (56.1%) and neck pain for OWs (51.5%). The most often reported MSP-1 was shoulder pain for nurses and OWs (84.4% and 65.7%, correspondingly), and elbow pain for CGs (74.9%). In the the entire sampled group, low back pain (53.9%) in the past 12 months and shoulder pain (70.9%) in the past month were the most often reported pain regions. A higher prevalence of multiple and disabling MSP and sickness absence were reported by CGs, compared to other occupation groups (p < 0.05). Correlation analysis showed positive relationships between job-related risk factors, like repetitive movements, physical load, and time demands, and MSPs and sick leave, especially among CGs (p < 0.05). Job-specific factors need more attention to prevent multiple and disabling pain and sick leave among office and hospital workers.
Detection of Persistent Organic Pollutants in Blood Serum of Electricians and Welders in Latvia
Authors: Sudmalis Pāvels , Baķe Mārīte Ārija , Rotbergs Juris
Published: December 2016

Persistent organic pollutants (POPs) are chemical substances that persist in the environment, bioaccumulate through the food web, and pose a risk of causing adverse effects to human health and the environment. The aim of the study was to assess the POP (polychlorinated biphenyls (PCBs), polybrominated diphenylethers (PBDEs), DDT and their derivatives) levels in blood serum to identify possible risk group workers. Blood serum samples (116 in total) were collected from two groups of employees — electricians, who can come in contact with PCB-containing transformer and capacitor oil, and welders, who were used as a control group. Sample purification was done by double solid phase extraction. The concentrations of POPs in blood serum were determined by gas chromatography with electron capture detector GC/ECD and recovery controlled by internal standard CB-174. None of the 116 samples contained the full range of tested POPs. However, all samples contained at least one of pesticides, and a marker PCB and mono-ortho PCB. Blood serum samples of 52% of electricians and 97.8% of welders contained non-ortho PCB compared to 84% and 74.7%, respectively, for PBDE’s. The concentrations of 18 detected PCBs, 4 detected PBDEs and 6 chlorinated pesticides and their metabolites varied in wide ranges and the differences in mean values between groups were not statistically significant (p > 0.05). The estimated concentrations of POPs correspond to the lowest levels detected in other countries. Mean concentrations of low-chlorinated marker PCBs were higher in the electrician group, suggesting that the employment sites are contaminated with PCBs, or that employees have contact with PCB-containing items.
Proposal of English equivalents for the soil taxa names in the Polish Soils Classification
Authors: Świtoniak Marcin , Kabała Cezary , Charzyński Przemysław
Published: December 2016

The article presents proposed English translations of all names of soil units (orders, types and subtypes) listed by Polish Soils Classification, PSC (2011). The proposal has been elaborated based on the recent Polish and foreign literature, using uniform and consistent criteria. Due to the lack of soil names translation in the recent, fifth edition of PSC, the suggested English nomenclature was basically derived from the previous, fourth edition of PSC (1989). However, significant amendment and numerous additions to the latest version were proposed. A uniform and comprehensive system of soil taxa translations may help to avoid nomenclature chaos in the English papers of Polish authors, which intentionally base or refer to PSC.
Deceptive Signification: Walter Scott, Ivanhoe, and Eighteenth-Century Hermit Discourse
Authors: Sommer Tim
Published: December 2016

Since the latter part of the nineteenth century, critics have tended to treat Walter Scott’s fiction disparagingly – the tacit assumption often being that it lacks formal sophistication or semantic ‘depth.’ Reading Scott against the grain of this reception, I argue here that Ivanhoe (1819/1820) commands an allusive density which complicates such verdicts. Offering a detailed analysis of both the novel’s hermit figure and the cultural geography in which it appears, this essay retraces Scott’s references to eighteenth-century literary, aesthetic, architectural, and horticultural discourses. Acutely aware of drawing from a codified set of readily consumable images, Scott both quotes and subverts the eighteenth-century hermit tradition. Employing an elaborately intertextual strategy to defamiliarize readerly notions of identity and signification, Scott’s writing emerges as somewhat more complex than the history of his critical reception would seem to suggest.
Noradrenaline from Locus Coeruleus Neurons Acts on Pedunculo-Pontine Neurons to Prevent REM Sleep and Induces Its Loss-Associated Effects in Rats
Authors: Khanday Mudasir Ahmad , Somarajan Bindu I. , Mehta Rachna , Mallick Birendra Nath
Published: December 2016

Normally, rapid eye movement sleep (REMS) does not appear during waking or non-REMS. Isolated, independent studies showed that elevated noradrenaline (NA) levels inhibit REMS and induce REMS loss-associated cytomolecular, cytomorphological, psychosomatic changes and associated symptoms. However, the source of NA and its target in the brain for REMS regulation and function in health and diseases remained to be confirmedin vivo. Using tyrosine hydroxylase (TH)-siRNA and virus-coated TH-shRNA in normal freely moving rats, we downregulated NA synthesis in locus coeruleus (LC) REM-OFF neuronsin vivo. These TH-downregulated rats showed increased REMS, which was prevented by infusing NA into the pedunculo-pontine tegmentum (PPT), the site of REM-ON neurons, normal REMS returned after recovery. Moreover, unlike normal or control-siRNA- or shRNA-injected rats, upon REMS deprivation (REMSD) TH-downregulated rat brains did not show elevated Na-K ATPase (molecular changes) expression and activity. To the best of our knowledge, these are the firstin vivofindings in an animal model confirming that NA from the LC REM-OFF neurons (1) acts on the PPT REM-ON neurons to prevent appearance of REMS, and (2) are responsible for inducing REMSD-associated molecular changes and symptoms. These observations clearly show neuro-physio-chemical mechanism of why normally REMS does not appear during waking. Also, that LC neurons are the primary source of NA, which in turn causes some, if not many, REMSD-associated symptoms and behavioral changes. The findings are proof-of-principle for the first time and hold potential to be exploited for confirmation toward treating REMS disorder and amelioration of REMS loss-associated symptoms in patients.
Expo Milano: Capitalist Dreams and Eating Machines
Authors: Feinberg Rebecca
Published: December 2016

Expo Milano, the 2015 World Fair, promised visitors an experience that would change how we imagine feeding the planet in the generations to come. Dozens of nations constructed monumental pavilions and spectacles, creating a Disneyland-like environment of cleverly concealed technologies and mass entertainment. For the 20 million people who came to play at social justice or sample bites of sustainability, what did Expo Milano really offer? What questions were asked, what experiences created, and what did visitors leave with at the end of the day? This article critiques the event for its profit-based design and logics, depicting a theme park simulacrum that gave visitors a high tech but empty-handed role in thinking or doing foodways differently. In addition to examining Expo Milano's shortcomings, I also point to the kinds of innovations and interactions that might allow us to imagine a more dynamic—and challenging—future of food.
Fostering Multiple Goals in Farm to School
Authors: Lakind Alexandra , Skipper Lihlani , Morales Alfonso
Published: December 2016

In the United States, the farm to school movement has recently spread from fringe and grassroots to mainstream. As schools expand their participation, there is a rapidly growing demand to scale up food distribution. Yet, in the rush to support “farm” and “school,” the supply chain, made up of the aggregation, processing, distribution, and logistics services, has been overlooked. Paying attention to the ways in which the standard model is incongruent with goals of the movement incites possibilities for new types of supply chain that reorient from profit and efficiency toward regional economy and transparency. This article elucidates a cooperative framework consisting of three primary aims: sustain the values of the movement; successfully scale up food distribution, expanding access to local, nutritious food; and support the negotiations needed to achieve individual and collective goals. This university/community collaboration evinces the great potential for cooperatives to play a significant role in future supply chain partnerships.
Live and Active Cultures: Gender, Ethnicity, and “Greek” Yogurt in America
Authors: Gurel Perin
Published: December 2016

Using a transnational and comparative cultural studies approach, this essay investigates how yogurt, perceived as a strange and foreign food in the early to mid-twentieth-century United States, became localized through intersectional processes of feminization and de-exoticization. In the transition from the 1970s to the 1980s, the dairy industry adopted a postfeminist ethos, which co-opted the hippie and feminist self-care movements that had made yogurt a staple health food outside the purview of the medical-industrial complex and on the margins of the market economy. Increasingly, yogurt was marketed to the prototypical (white middle class) dieting female, expected to discipline her body by consuming pre-proportioned approximations of dessert. The rising popularity of “Greek yogurt” in the early twenty-first century has modified this cultural neutralization by foregrounding a nonthreatening “white” ethnicity—while furthering the feminization of yogurt consumption and obscuring connections to the food cultures of the Middle East.
Círculos viciosos: migración y violencia en la narrativa y el cine trans-centroamericanos
Authors: Espinoza Mauricio
Published: December 2016

La migración, tanto intra-ístmica como trans-ístmica, ha marcado la vida de millones de centroamericanos a finales del siglo XX y principios del siglo XXI. Este ensayo analiza dos obras representativas del reciente subgénero narrativo de la migración centroamericana: la novela The Tattooed Soldier (El soldado tatuado, 1998), de Héctor Tobar, y el largometraje El camino (2007), dirigido por Ishtar Yasin. En él se arguye que ambos textos abordan la migración de ciudadanos  centroamericanos mediante una estrategia narrativa identificada como “violencia circular desterritorializada”. En este sentido, la violencia inicial (nacional, territorializada) migra junto a los protagonistas hacia los países receptores, transformándose en un fenómeno transnacional y desterritorializado. Debido al carácter transnacional y circular de esta violencia, los personajes no logran escapar de ella y más bien terminan en peores circunstancias después de migrar a la supuesta “tierra prometida”. Por medio  de esta estrategia narrativa, The Tattooed Soldier y El camino critican la forma en que los centroamericanos más vulnerables han sido víctimas de una violencia estructural e institucionalizada que se extiende más allá del territorio nacional y cuyo origen y causa común es la desigualdad socioeconómica y la precariedad que marcan a estos individuos antes y después de convertirse en migrantes.
Barriers of Pediatric Residents to Speaking Up About Patient Safety
Authors: Landgren Rachel , Alawadi Zeinab , Douma Caryn , Thomas Eric J , Etchegaray Jason
Published: December 2016

BACKGROUND AND OBJECTIVES:

Medical errors are a leading cause of death in the United States. Effective communication and speaking up are crucial factors in patient safety initiatives. We examined the reasons reported by pediatric residents for not speaking up about safety events when they are observed in practice. We also tested a priori hypotheses of associations between categories of barriers to speaking up with perceptions of safety and teamwork culture.

METHODS:

Pediatric residents completed an anonymous electronic survey measuring safety and teamwork culture along with an open-ended question asking them to list the top 3 barriers to speaking up about patient safety concerns. Researchers independently coded the open-ended responses to identify themes, which were then categorized into a published framework. Data were collected in 2013 (response rate = 46%) and 2014 (response rate = 62%).

RESULTS:

The most common reported barriers to speaking up were as follows: perceived personal safety of speaking up (consequences, intimidation, and hierarchy concerns), individual barriers (communication skills and confidence), perceived efficacy of speaking up (feeling powerless), and contextual factors (high workload). Residents who reported barriers relating to efficacy of speaking up reported lower safety culture scores in 2013 and 2014. Residents who reported barriers related to safety reported lower teamwork culture scores in 2013.

CONCLUSIONS:

Pediatric residents reported individual barriers, personal safety concerns, lack of efficacy, and contextual factors as reasons to not speak up about patient safety. Concerns about the safety of speaking up and the efficacy of speaking up were correlated with teamwork and safety culture, respectively.
Pediatric Medication Safety in Adult Community Hospital Settings: A Glimpse Into Nationwide Practice
Authors: Alvarez Francisco , Ismail Lana , Markowsky Allison
Published: December 2016

BACKGROUND AND OBJECTIVES:

Most children in the United States are treated in adult settings. Studies show that the pediatric population is vulnerable to medication errors. It can be extrapolated that children cared for in adult settings are at equal or higher risk for errors. The goal of this study was to assess the existing pediatric medication safety infrastructure within adult hospitals.

METHODS:

Questionnaire developed through Research Electronic Data Capture (REDCap) and distributed to pediatric hospitalist programs listed on the American Academy of Pediatrics, Section on Hospital Medicine web site and members of the American Academy of Pediatrics Quality Improvement Innovation Networks listserv. There were >20 questions regarding the use of various safety measures and characteristics of the hospital.

RESULTS:

Thirty-eight program staff and 26 Quality Improvement Innovation Networks listserv members completed the survey (total = 64). Of these, 90.6% use order sets or computerized provider order entry with pediatric weight-based dosing, 79.7% review pediatric medication safety events or concerns, 58.7% were aware that their hospital had defined or documented maximum doses on orders, and 50.0% had milligram-per-kilogram dosing required to be in the order. A majority of respondents document weights only in the metric system (kilograms or grams) in both the emergency department and the pediatric unit (84.4% and 92.1%, respectively). A total of 57.8% of hospitals had pharmacists trained in pediatrics, with hospitals with >300 beds more likely to have a pediatric pharmacist than those with <300 beds (75% vs 44%, P ≤ .05).

CONCLUSIONS:

Pediatric medication safety infrastructure shows variations within the sites surveyed. Our results indicate that certain deficiencies are more widespread than others, providing opportunities for targeted, but hospital-specific interventions.
Peripheral Nerve Disorders in the Neonate
Authors: Choi Hyoung Won , Kuntz Nancy L.
Published: December 2016

The diagnosis of peripheral nerve disorders in the neonate is challenging because of a wide range of conditions that can present with similar clinical features. The neonate with peripheral nerve disorders typically manifests generalized hypotonia with or without respiratory insufficiency. Diseases with lesions at various levels of the central or peripheral nervous system, as well as myriad systemic conditions, can all present with the same clinical features at birth. Neurophysiologic testing, appropriate genetic evaluation including detailed family history, cerebrospinal fluid analysis, and most importantly, careful neurologic examination and observation of the clinical course will help narrow down the differential diagnosis. This review aims to introduce representative forms of peripheral nerve disorders during the newborn period. We will discuss clinical features, how to differentiate between the disease entities, and the implications of early diagnosis and prognosis.
Occurrence of Cr-bearing beryl in stream sediment from Eskişehir, NW Turkey
Authors: Erkoy Hülya , Kadir Selahattin
Published: December 2016

Beryl crystals are found within stream sediments transecting schists in the northeast of Eskişehir, western Anatolia. This paper studied the Eskişehir beryl crystals with optical microscopy, scanning electron microscopy (SEM-EDX), infrared spectroscopy (IR) and geochemical analyses. Beryl is accompanied by garnet, glaucophane, quartz, epidote, muscovite and chlorite in the stream sediments. The crystals are euhedral emerald (green gem beryl) and light bluishgreen aquamarine, with ideal sharp IR bands. Wet chemical analysis of Eskişehir beryl yielded 61.28% SiO2, 15.13% Al2O3, 12.34% BeO, 0.18% Cr2O3, 1.49% MgO, 1.69% Na2O, 0.98% Fe2O3, and 0.008% V2O3, resulting in the formula (Al1.75Cr0.01Mg0.22Fe0.08)(Be2.90Si6.00)(Na0.32)O18. Large Ion Lithophile Elements (LILE) (barium, strontium), some transition metals (cobalt, except nickel) and High Field Strength Elements (HFSE) (niobium, zirconium, and yttrium) in stream sediments that are associated with beryl exhibited low content about metamorphic rocks. Beryl formation appears to be controlled by upthrust faults and fractures that juxtaposed them with Cr-bearing ophiolitic units and a regime of metasomatic reactions. Such beryl crystals have also been found in detrital sediments that are derived from the schists. Presencia de berilios relacionados con Cromo en corrientes sedimentarias de Eskisehir, noroeste de Turquía  ResumenCristales de berilio fueron encontrados en sedimentos de corrientes que atraviesan en esquistos en el noreste de Eskisehir, al oeste de Anatolia.

El berilio estaba acompañado de granate, glaucofana, cuarzo, epidota, moscovita, y clorito en las corrientes sedmientarias. Los cristales son esmeraldas de formas definidas (gema verde de berilio) y aguamarinas color verde celeste, con bandas de espectroscopia infrarroja de buena nitidez. El análisis químico húmedo del berilio de Eskisehir mostró 61.28 % de SiO2, 15.13 % de Al2O3, 12.34 % de BeO, 0.18 % de Cr2O3, 1.49 % de MgO, 1.69 % de Na2O, 0.98 % de Fe2O3, y 0.008% de V2O3, lo que resulta en la formula (Al1.75Cr0.01Mg0.22Fe0.08)(Be2.90Si6.00)(Na0.32)O18. Los elementos litófilos de ion grande (bario, estroncio), algunos metales de transición (cobalto, excepto níquel) y los elementos de gran campo de fuerza (niobio, circonio e itrio) en las corrientes de sedimentos que están con berilio mostraron un bajo contenido sobre las rocas metamórficas. Las formaciones de berilio aparecen controladas por fallas de cabalgamiento y fracturas que se yuxtaponen con las unidades ofiolíticas relacionadas con cromo y un régimen de reacciones metasomáticas. Estos cristales de berilio se han encontrado también en sedimentos detríticos que se derivan de los esquistos.
Fronteras del mito, la filosofía y la ciencia. De los mitos cosmogónicos a la teoría del Big Bang
Authors: Ordóñez Díaz Leonardo
Published: December 2016

C. Lévi-Strauss advirtió que la variedad de mitos, lejos de constituir una proliferación anárquica de relatos, exhibe un aire de familia que trasparenta la profunda unidad del pensamiento humano. A partir de esta idea, el artículo muestra cómo ciertas teorías filosóficas y científicas sobre el origen del cosmos se apoyan en una estructura narrativa implícita en los mitos cosmogónicos. Esta comparación evidencia inesperadas afinidades en el intento por responder la pregunta por el origen del cosmos.
Antimicrobial test of roselle (hibiscus sabdariffa L.) ethanol extract againts porphyromonas gingivalis and streptococcus sanguis using agar method (in vitro study)
Authors: Indriani Lenni , Dharmautama Mohammad
Published: December 2016

The use of natural materials in the world of health tends to increase every single year, including  in dentistry. Due to the increased of resistance to antibiotics, the development and new innovations to obtain a new antimicrobial agent. Some potential sources of plants have been studied. One of the natural plants is used as drinks, food, medicine and antimicrobial agent is Hibiscus sabdariffa Linn commonly known as Roselle. Several major Gram-negative bacteria are related to periodontal disease such as Porphyromonas gingivalis (P.gingivalis), The dominant species of Gram-positive including Streptococcus sanguis(S.sanguis). The purpose of this in vitro study is to evaluate the Roselle ethanol extract against P.gingivalis bacteria (Gram negative bacteria) and S. sanguis (Gram positive bacteria) with a concentration of 2.5%, 5%, 7.5% and 10%. The in vitro study of antibacterial effectiveness of Roselle (Hibiscus sabdariffa L.) ethanol extract on P.gingivalis and S. sanguis. Natrium Agar (NA) solution was poured into a glass plate which had previously been sterilized and then left in place until the medium solidified. P.gingivalis and S.sanguis bacterial cultures were inoculated with inscribed which had solidified. Then put paper disk which had previously been saturated with Roselle extract samples with a concentration of 2.5%, 5%, 7.5% and 10%, and the negative control at the surface of the medium (Ampicillin) and incubated for 1 day. Clear zone is formed then observed and measured. There are 24 samples, consisting of 12 samples  P.gingivalis and S.sanguis 12 samples, given intervention roselle flower extract with four types of concentrations to determine the minimum inhibitory consentration (MIC). The observations show that the extensive zone of inhibition concentration of 2.5% a broad zone of inhibition is the smallest among other concentration, both of S.sanguins and P.gingivalis. Meanwhile, the average increases the broad zones of inhibition of P.gingivalis followed by increasing concentrations of roselle flower extract, making it the largest broad zones of inhibition are shown at a concentration of 10%, However, the bacteria S.sanguins, shows that vast zone of greatest inhibition was found at a concentration of 7.5%. The results of this research showed that the ethanol extract of roselle effectively inhibits P. gingivalis as Gram-positive bacteria atconcentrations of 10% and S. sanguins at a concentration of 7.5%. Iit can be concluded that the ethanol extract of roselle flowers effective at inhibiting Gram positive and Gram negative bacteria.
Pradhan Mantri Jan-DhanYojana – A Game Changer for the Economy
Authors: Sharma Sunita
Published: December 2016

Financial inclusion is a national priority as it is an enabler for inclusive growth. It is important to take banking services to the unbanked and under banked areas, and to the people who are hitherto excluded and left to fend for themselves for their financial needs. In order to provide the much needed thrust to financial inclusion, a flagship programme called the ‘PradhanMantri Jan-DhanYojana’ (PMJDY) was announced by Honourable Prime Minister on 15th August 2014. This paper presents an overview of the scheme. An analysis of views of 50 customers covered under the scheme of State Bank of India is summarized, followed by concerns raised and the way forward.
Empowerment of Microfinance Beneficiaries in India and Bangladesh: A Factor Analysis Approach
Authors: Chakraborty Rajib , Vasanthagopal R.
Published: December 2016

It is a widely known fact that micro finance plays an important role in empowering the poorer section of the population, particularly rural women, who traditionally lack access to the banking related services. From its basic norm to providing small amount of loan to the poor women to implement a number of social development programmes, micro finance is now considered as a tool of women empowerment. The present paper aims to identify the socio-economic factors that affect the empowerment level of microfinance beneficiaries in India and Bangladesh most. Further, it checks whether demographic characteristics of the beneficiaries have any association with the identified factors.

Authors: Latheef E. N. Abdul , Muhammed K. , Riyaz Najeeba , Binitha M. P.
Published: December 2016

Background: Vitiligo is a common skin disease affecting 1%-2% of general population. Even though different modalities of treatment available, it remains as a difficult disease to treat. Many cases remain stable after a period of medical therapy without any further response. Surgical techniques are the only hope in such patients. The aim of this study was to evaluate the response of autologous, noncultured melanocyte keratinocyte cell transplantation in patients with stable focal vitiligo.

Methods: A retrospective study of 100 cases focal vitiligo treated by autologous, noncultured melanocyte-keratinocyte cell transplantation. Serial of photographs were taken on each visit. The patents were followed for a period of 5 years. The results were analyzed on a visual analogue scale.

Results: Out of total 100 patients, 44 had excellent (90 to 100%) response, 18 had good (60 to 89%) response, 12 had fair (25 to 59%) response and 26 had poor response (0 to 24%). Age and sex of the patients and size and duration of lesions, did not show significant influence on results of transplantation.

Conclusions: This is a simple, safe, and effective surgical therapy for replenishing the missing melanocytes in resistant cases of vitiligo. Repigmentation lasts long with very good cosmetic acceptability.

Published: December 2016

Despite the wealth of data on RNA secondary structure, conformational dynamics and tertiary structure in vitro and in vivo, predicting RNA biological activity in cellular environments remains difficult. Here we describe a method of in silico RNA fingerprinting that allows efficient design of hammerhead ribozyme molecules with a high intracellular efficiency. Our method, which we call RNA dactyloscopy, is a reliable tool for assessing catalytic properties, modeling and design of RNA.
INTEGRASI PENGAJIAN SAINS-TEKNOLOGI DAN PENGAJIAN SYARIAH: SATU PENILAIAN SEMULA
Authors: Azhar Alias
Published: December 2016

The development of shariah is being questioned because it has deviated from the original purpose and tends to focus more on formal aspects than on its application and usefulness for life. Therefore, it is the time to re-evaluate the strategy and execution of all forms of shariah to fit with the modern era and improve the business of ummah to cover the advancement of science and technology. There are two choices in establishing the patterns of shariah studies. First, follow the trends with tecnical, bureaucratic and legal also formal rule that will make Islamic shariah static. Secondly, formulate the paradigm of integrated shariah studies covering the development of science and technology whose purpose is to establish a dynamic and responsive Islamic law to the problems of society.
KONSEP INGSUN DALAM SASTRA SUFI JAWA: Analisis Terhadap Ingsun Siti Jenar
Authors: Fauzan Aris
Published: December 2016

Pembicaraan tentang Syekh Siti Jenar dan ungkapannya Iya Ingsun iki Allahmenimbulkan polemic di kalangan masyarakat, hingga melahirkan kesimpulan bahwaSyekh Siti Jenar mengaku sebagai Tuhan, Allah. Namun membaca teks-teks sufismeJawa, tidak bisa hanya membaca dan memaknai secara harfiah suatu ungkapan yangterpisah. Begitu pula membaca pernyataan Syekh Siti Jenar Iya Ingsun iki Allah.Untuk memahaminya diperlukan rujukan lain seperti Suluk Acih, Serat SulukWalisana, dan tiga Serat Siti Jenar masing-masing karya Raden Sasrawijaya, RadenMas Ngabehi Mangunwijaya, dan Raden Mas Harjawijaya. Berdasarkan pada tigapembacaan terhadap teks-teks tersebut dengan menggunakan pendekatan integrasiinterkoneksitekstual, dapat disimpulkan bahwa ingsun mempunyai arti yang tidaktunggal. Dalam hal ini ingsun berarti, hakikat Tuhan, ingsun sebagai ungkapanpuncak rohani, ingsun sebagai representasi manusia sempurna, dan ingsun sebagaibentuk pembicaraan dua orang yang mempunyai derajat yang sama atau saling marah.Dijatuhkannya hukuman pada Syekh Siti Jenar atas pertimbangan social politiksemata. Karena pada kenyataannya para wali tidak menolak konsep-konsep ingsunyang ada dalam ajaran sufisme Siti Jenar.
