Published: June 2019

Organization Citizenship Behavior (OCB) is known to have important role for supporting employee performance in a company. Considering this positive outcomes for company, many researcher began to gave interest on this topic. This study aimed to see the role of personal value on employees OCB behavior. The study was conducted on 30-dyads employee and their supervisor from several types of industrial backgrounds. Unlike previous OCB studies in Indonesia, this time, OCB would be measured using a rating from the supervisor. Personal value will be masured by employee self-report. Thus, common method variance bias can be avoided. The result show that only achievement values significantly affect OCB behavior, meanwhile power and benevolence did not significantly affect OCB behavior.

Published: June 2019

Due to rise in drug resistance among pathogens, there is always an urge to look for new drug alternatives. So in this study we aimed to identify the unexplored rhizosphere microflora of alfalfa plant for new antimicrobials. With initial screening for isolates from rhizosphere region for antibacterial activity against selected bacterial pathogens, the isolate AL10 had better activity selected for this study. The isolate mass was cultured and secondary metabolites were extracted using ethyl acetate and subjected to FTIR and GC-MS analysis. Based on functional diversity analysis, the isolate subjected to anti-bacterial activity revealed significant activity against Streptococcus pneumonia, Klebsiella, S. aureus with zone of inhibition in the range of18-20 mm. Based on GC-MS analysis report ten compounds were identified and 1-Octadecane and 1-nonadecanol were found to be responsible for bio-activity. FT-IR results showed that N-H stretching functional group was dominantly present in the extract. Molecular identification of the isolate by 16S rRNA sequencing showed the isolate as Pantoea agglomerans. The results showed that the isolate P.agglomerans, gram negative bacteria had wide antibacterial activity due to 1-Octadecane and 1-nonadecanol. Though Alfalfa plant has been described for various biological activities, this is a first report on rhizosphere region of plant reporting for antibacterial potential microbes.

Dam inflow forecasting information is essential for planning and management of the dam system. Time series analysis is the most commonly employed technique to forecast the future values based on historical information. In this study, Palar-Porandalar dam in Tamil Nadu inflow series were forecasted in R software package using ARIMA model with seasonal factors. The monthly inflow series of the dam from 2003 January to 2017 December were used as an input source for modeling and forecasting process. Mann-Kendall’s trend test and various Stationarity test were performed to verify the Stationary nature of the data set. From the Correlogram plot, different models were identified; their parameters were optimized and residuals were diagnostically tested using Autocorrelation plot and Ljung Box test. Finally, the best model was selected based on minimum Akaike Information Criteria (AIC), BIC, RMSE and Theil’s U statistic values. From various models, SARIMA (0, 0, 1) (1, 0, 2)12 model was selected as the best one for forecasting the inflow series.
Effect of UV-B radiations on mortality and enzymes level in fish larvae of Tor tor and Schizothorax richardsonii on laboratory scale
Authors: Kumar Sunil , Malik D. S. , Rathi Prachi
Published: June 2019

Depletion of stratospheric ozone layer is resulting into increase in solar UV-B on earth surface. Ultra violet radiation is well known to cause many detrimental effects in aquatic organisms. The present study was performed to study the effect of solar ultraviolet radiation on fish fingerlings of Tor tor and Schizothorax richardsonii as a model system on laboratory scale. The effect of different intensities of natural solar and artificial UV-B radiation on fish larvae of T. tor and S. richardsonii in a presence of retene was investigated. Solar ultraviolet intensity showed seasonal and altitudinal variations in Garhwal region. Solar UV radiation level was lower (0.390 mw/cm2) in the month of January- February at lower altitude and highest (1.192 mw/cm2) in the month of July-August 2018 at higher altitude. Fish larvae exposed to artificial UV-B (average wavelength 312 nm and intensity of 750 mw/cm2) with retene (50µg/l) showed increase in gills malandialdehyde level and caused larvae mortality as indicating that enhanced solar UV-B exposure could be lethal to fish fauna in aquatic ecosystem. Artificial UV-B had a stronger damaging effect on fish larvae than solar radiation exhibited highly toxic in presence of retene. The larvae of S. richardsonii was found more sensitive than T. tor as indicated by high mortality rate (30%) and high pigmented characteristics on dorsal side. The solar and ultraviolet radiation showed a positive effect on high pigmentation. These results suggest that on a short time scale, UV-B radiation causing developmental stress on fish larvae may contribute to assess the phototoxic behaviour of cold water fishes.

Cross-cultural data shows musical scales evolved to maximise imperfect fifths
Authors: Mcbride John , Tlusty Tsvi
Published: June 2019

Musical scales are used throughout the world, but the question of how they evolved remains open. Some suggest that scales based on the harmonic series are inherently pleasant, while others propose that scales are chosen that are easy to communicate.However, testing these theories has been hindered by the sparseness of empirical evidence. Here, we assimilate data from diverse ethnomusicological sources into a cross-cultural database of scales. We generate populations of scales based on multiple theories and assess their similarity to empirical distributions from the database. Most scales tend to include intervals which are close in size to perfect fifths (“imperfect fifths”), and packing arguments explain the salient features of the distributions. Scales are also preferred if their intervals are compressible, which may facilitate efficient communication and memory of melodies. While scales appear to evolve according to various selection pressures, the simplest, imperfect-fifths packing model best fits the empirical data.
Relationships among Carbon Emissions, Economic Growth, Energy Consumption and Population Growth: Testing Environmental Kuznets Curve Hypothesis for Brazil, China, India and Indonesia
Authors: Alam Md. Mahmudul , Murad Wahid , Noman Abu Hanifa Md. , Ozturk Ilhan
Published: June 2019

This study examines the impacts of income, energy consumption and population growth on CO2 emissions by employing an annual time series data for the period 1970-2012 for India, Indonesia, China, and Brazil. The study used the Autoregressive Distributed Lag (ARDL) bounds test approach considering both the linear and non-linear assumptions for related time series data for the top CO2 emitter emerging countries in both the short run and long run. The results show that CO2 emissions have increased statistically significantly with increases in income and energy consumption in all four countries. While the relationship between CO2 emissions and population growth was found to be statistically significant for India and Brazil, it has been statistically insignificant for China and Indonesia in both the short run and long run. Also, empirical observations from the testing of environmental Kuznets curve (EKC) hypothesis imply that in the cases of Brazil, China and Indonesia, CO2 emissions will decrease over the time when income increases. So based on the EKC findings, it can be argued that these three countries should not take any actions or policies, which might have conservative impacts on income, in order to reduce their CO2 emissions. But in the case of India, where CO2 emissions and income were found to have a positive relationship, an increase in income over the time will not reduce CO2 emissions in the country.

Published: June 2019

This research aims at examining the direct and indirect impacts of climatic changes as well as the effects of non-climatic factors on household food security in Malaysia. The study is based on primary data collected in the months of July – October, 2012 through a questionnaire survey on 460 low income households from East Coast Economic Region (ECER) of the country. The samples were selected from E-Kasih poor household database, based on cluster random sampling technique. The statistical estimation was done through two-stage formative path measurement model by using nonparametric bootstrap procedure under Smart PLS. This study finds that household food insecurity ECER – Malaysia is not only related to social and economic factors, but also statistically significantly linked to the direct and indirect impacts of climatic factors. The policy implications of the study suggest that design of food security programs must be integrated with climatic change adaptation programs. The government and other relevant agencies should jointly develop appropriate policies for poverty alleviation, household level food security, and adaptation with climatic changes in Malaysia.

Best Practice in Supporting Professional Identity Formation: Use of a Professional Reasoning Framework
Authors: Armitage-Chan Elizabeth
Published: June 2019

Professional identity and professionalism education are increasingly important to veterinary education, but many of the concepts remain intangible to veterinary students, and engagement is a persistent challenge. While whole-curriculum integration is recommended for a successful professional studies program, this is complicated by clinical faculty’s discomfort with the content. Where professional studies education is centered around professional identity formation, a key element of this is the multi-perspective nature of veterinary work, with the veterinarian negotiating the needs of multiple stakeholders in animal care. Constructing teaching around a framework of professional reasoning, which incorporates the negotiation of different stakeholder needs, ethical decision making, communication, teamwork, and outcome monitoring, offers the potential to make professional identity a concept more visible to students in veterinary work, and guides students in the contextualization of taught material. A framework is presented for veterinary professional reasoning that signposts wider curriculum content and helps illustrate where material such as veterinary business studies, animal welfare, the human–animal bond, and professional responsibility, as well as attributes such as empathy and compassion, all integrate in the decisions and actions of the veterinary professional. The aims of this framework are to support students’ engagement in professional studies teaching and help them use workplace learning experiences to construct an appropriate professional identity for competence and resilience in the clinic. For faculty involved in curriculum design and clinical teaching, the framework provides a tool to support the integration of professional identity concepts across the extended curriculum.

Health interregionalism in combating communicable diseases
Authors: Rollet Vincent
Published: June 2019

This last decade, regional organizations progressively became
unavoidable actors of regional health governance and have been supported by some global health actors to strengthen such a role. Among these actors, the European Union (EU) is the only regional organization that implements health initiatives in cooperation with its regional counterparts. This article focuses on such “health interregionalism” toward Southeast Asia and Africa and in the field of communicable diseases, with the main objective of assessing its nature and identifying its main functions. It concludes that although appreciated and needed, the EU’s health interregionalism should better reflect the EU’s experience in regional health governance in order to represent a unique instrument of development aid and an added value for regional organizations
Wide-neck aneurysms: systematic review of the neurosurgical literature with a focus on definition and clinical implications

Published: June 2019

OBJECTIVE

Wide-necked aneurysms (WNAs) are a variably defined subset of cerebral aneurysms that require more advanced endovascular and microsurgical techniques than those required for narrow-necked aneurysms. The neurosurgical literature includes many definitions of WNAs, and a systematic review has not been performed to identify the most commonly used or optimal definition. The purpose of this systematic review was to highlight the most commonly used definition of WNAs.

METHODS

The authors searched PubMed for the years 1998–2017, using the terms “wide neck aneurysm” and “broad neck aneurysm” to identify relevant articles. All results were screened for having a minimum of 30 patients and for clearly stating a definition of WNA. Reference lists for all articles meeting the inclusion criteria were also screened for eligibility.

RESULTS

The search of the neurosurgical literature identified 809 records, of which 686 were excluded (626 with < 30 patients; 60 for lack of a WNA definition), leaving 123 articles for analysis. Twenty-seven unique definitions were identified and condensed into 14 definitions. The most common definition was neck size ≥ 4 mm or dome-to-neck ratio < 2, which was used in 49 articles (39.8%). The second most commonly used definition was neck size ≥ 4 mm, which was used in 26 articles (21.1%). The rest of the definitions included similar parameters with variable thresholds. There was inconsistent reporting of the precise dome measurements used to determine the dome-to-neck ratio. Digital subtraction angiography was the only imaging modality used to study the aneurysm morphology in 87 of 122 articles (71.3%).

CONCLUSIONS

The literature has great variability regarding the definition of a WNA. The most prevalent definition is a neck diameter of ≥ 4 mm or a dome-to-neck ratio of < 2. Whether this is the most appropriate and clinically useful definition is an area for future study.

Authors: Hughes Marion A. , Jani Ronak H. , Fakhran Saeed , Chang Yue-Fang , Branstetter Barton F. , Thirumala Parthasarathy D. , Sekula Raymond F.
Published: June 2019

OBJECTIVE

The aim of this study was to identify preoperative imaging predictors of surgical success in patients with classic trigeminal neuralgia (cTN) undergoing microvascular decompression (MVD) via retrospective multivariate regression analysis.

METHODS

All included patients met criteria for cTN and underwent preoperative MRI prior to MVD. MR images were blindly graded regarding the presence and severity (i.e., mild or severe) of neurovascular compression (NVC). All patients were contacted by telephone to determine their postoperative pain status.

RESULTS

A total of 79 patients were included in this study. Sixty-two patients (78.5%) were pain-free without medication following MVD. The following findings were more commonly observed with the symptomatic nerve when compared to the contralateral asymptomatic nerve: NVC (any form), arterial compression alone, NVC along the proximal trigeminal nerve, and severe NVC (p values < 0.0001). The only imaging variable that was a statistically significant predictor of being pain-free without medication following MVD was severe NVC. Patients with severe NVC were 6.36 times more likely to be pain-free following MVD compared to those without severe NVC (p = 0.007).

CONCLUSIONS

In patients with cTN undergoing MVD, severe NVC on preoperative MRI is a strong predictor of an excellent surgical outcome.

OBJECTIVE

Prior studies have provided conflicting evidence regarding the contribution of key ligamentous structures to atlantoaxial (AA) joint stability. Many of these studies employed cadaveric techniques that are hampered by the inherent difficulties of testing isolated-injury scenarios. Analysis with validated finite element (FE) models can overcome some of these limitations. In a previous study, the authors completed an FE analysis of 5 subject-specific craniocervical junction (CCJ) models to investigate the biomechanics of the occipitoatlantal joint and identify the ligamentous structures essential for its stability. Here, the authors use these same CCJ FE models to investigate the biomechanics of the AA joint and to identify the ligamentous structures essential for its stability.

METHODS

Five validated CCJ FE models were used to simulate isolated- and combined ligamentous–injury scenarios of the transverse ligament (TL), tectorial membrane (TM), alar ligament (AL), occipitoatlantal capsular ligament, and AA capsular ligament (AACL). All models were tested with rotational moments (flexion-extension, axial rotation, and lateral bending) and anterior translational loads (C2 constrained with anterior load applied to the occiput) to simulate physiological loading and to assess changes in the atlantodental interval (ADI), a key radiographic indicator of instability.

RESULTS

Isolated AACL injury significantly increased range of motion (ROM) under rotational moment at the AA joint for flexion, lateral bending, and axial rotation, which increased by means of 28.0% ± 10.2%, 43.2% ± 15.4%, and 159.1% ± 35.1%, respectively (p ≤ 0.05 for all). TL removal simulated under translational loads resulted in a significant increase in displacement at the AA joint by 89.3% ± 36.6% (p < 0.001), increasing the ADI from 2.7 mm to 4.5 mm. An AACL injury combined with an injury to any other ligament resulted in significant increases in ROM at the AA joint, except when combined with injuries to both the TM and the ALs. Similarly, injury to the TL combined with injury to any other CCJ ligament resulted in a significant increase in displacement at the AA joint (significantly increasing ADI) under translational loads.

CONCLUSIONS

Using FE modeling techniques, the authors showed a significant reliance of isolated- and combined ligamentous–injury scenarios on the AACLs and TL to restrain motion at the AA joint. Isolated injuries to other structures alone, including the AL and TM, did not result in significant increases in either AA joint ROM or anterior displacement.

Published: June 2019

The content of the man-made radioactive nuclide 137Cs was investigated in different groups of the salt lakes of Crimea peninsula. One of the main sources of 137Cs was determined to be the North-Crimea channel, which supplied the Dnepr water to Crimea until 2014 with a high content of radioactive nuclides of Chernobyl origin. The other source of 137Cs is the Black Sea water owing to its drainage and direct connection with the coastal salt lakes of Crimea, which demonstrates a positive correlation between 137Cs concentration and water salinity.
Do “Tractatus” às “Observações filosóficas”: reflexões sobre a natureza da filosofia
Authors: Gonçalves Acríssio Luiz
Published: June 2019

No presente artigo, analiso a concepção de Wittgenstein sobre a natureza e a função da filosofia, discutindo o seu método deflacionista para o tratamento dos problemas filosóficos. Apresento os motivos pelos quais Wittgenstein teria compreendido a filosofia não como uma atividade descritiva, mas como uma atividade elucidativa, cujo propósito central seria dissolver os problemas filosóficos por meio da análise lógica (e/ou lógico-fenomenológica). Para cumprir este propósito, divido o artigo em três seções, nas quais discuto o pensamento de Wittgenstein a partir do Tractatus Logico-philosophicus (1921), de Some Remarks on Logical Form (1929) e das Philosophical Remarks (de 1929-1930), respectivamente. Nesse percurso, apresento a crítica de Wittgenstein à possibilidade de interpretar a filosofia como uma disciplina que, assim como a ciência, seja capaz de oferecer uma representação teórica sobre algum domínio de objetos ou fatos. Posteriormente, analiso algumas mudanças em sua descrição da atividade filosófica, mostrando que, até o início do período intermediário de sua filosofia, Wittgenstein mantém inalterada a ideia de que a função da filosofia seria a de estabelecer a distinção entre problemas teóricos reais (solucionáveis) e pseudoproblemas filosóficos.
Moral, ética e estética da existência em Michel Foucault
Authors: Carmo Miguel
Published: June 2019

O presente texto tem como objetivo não só precisar os conceitos de “moral”, “ética” e “estética da existência”, nos períodos estudados por Michel Foucault, como também captar suas diferenças significativas, tendo em vista o direcionamento para a possibilidade de uma ético-política na e da atualidade. Tais estudos arqueo-genealógicos da Grécia Clássica (século IV A.C.), do período Greco-Romano (séculos I-II D.C.) e do Cristianismo (séculos III-IV D.C.), mostram que os referidos conceitos mantem sua marca, de época em época, pela utilização de técnicas que visavam atingir a temperança e um cuidado de si cada vez maior e detalhado. A estilização da vida ganhou formas das mais variadas neste processo histórico, tendo como base práticas que, por vezes, aproximavam ou não a atitude moral da atitude ética. Essa flexibilidade dos usos dos conceitos, consequentemente, das práticas históricas e culturais, traz em Foucault a abertura do pensamento na busca de uma atitude política perante os atos, os pensamentos e a liberdade.

Tau is a phosphoprotein with natively unfolded conformation that functions to stabilize microtubules in axons. Alzheimer’s disease pathology triggers several modifications in tau, which causes it to lose its affinity towards microtubule, thus, leading to microtubule disassembly and loss of axonal integrity. This elicit accumulation of tau as paired helical filaments is followed by stable neurofibrillary tangles formation. A large number of small molecules have been isolated from Azadirachta indica with varied medicinal applications. The intermediate and final limonoids, nimbin and salannin respectively, isolated from Azadirachta indica, were screened against tau aggregation. ThS and ANS fluorescence assay showed the role of intermediate and final limonoids in preventing heparin induced cross-β sheet formation and also decreased hydrophobicity, which are characteristic nature of tau aggregation. Transmission electron microscopy studies revealed that limonoids restricted the aggregation of tau to fibrils; in turn, limonoids led to the formation of short and fragile aggregates. Both the limonoids were non-toxic to HEK293T cells thus, substantiating limonoids as a potential lead in overcoming Alzheimer’s disease.

Passive wheel speed sensors are widely used in automotive applications where knowledge of the rotational velocity of the rotating axes and resistant to environmental impacts are required. This paper presents a general introduction to wheel speed sensor systems and the underlying physical behaviour are explained with the help of three-dimensional time-stepping finite element method. The 3D field simulations well reflect the dynamics of the magnetic field of the real problem and they provide a quantitative understanding of the output signal behaviour concerning model parameter variations. The sensor geometry is analyzed in detail, featuring a study of the influence of the main parameters. As an outcome of parameter analysis, it was possible to determine the influence of the sensor parameters on the output signal of the sensor. In addition, this study aims to advance the understanding of the physical behaviour of passive wheel speed sensors by three-dimensional nonlinear finite element analysis, which is missing from the literature.
Modelling and experimental investigation of a squeeze mode magnetorheological damper
Authors: Meng Fanxu , Zhou Jin
Published: June 2019

In this paper, a novel mechanical model based on arc tangent function is established to accurately describe the hysteretic behavior of the squeeze mode Magnetorheological (MR) damper. An improved differential evolution (DE) algorithm, which can avoid the shortage of being easily trapped in a local extremum, is applied to identify the parameters of the model. The dynamical characteristic of the MR damper is experimentally investigated with the help of the MTS machine. The validity of the proposed model is confirmed from a good agreement between the simulations and measured data. In addition, comparative analysis of the simulations with two other existing models, reveals that the proposed model has a relatively high modelling accuracy with less parameters and explicit physical meaning.

Published: June 2019

The solenoid valve used on the hydraulic roof support in the coal mine is an intrinsically safe solenoid. It requires the solenoid valve to achieve large electromagnetic force at low current. The load can not be driven if the current is too low, while a large temperature rise and energy loss would occur in the form of heat if the current is too high. In order to solve this contradictory problem, the load force of the solenoid valve was analyzed first. Then the ANSYS models of the solenoid were established to carry out the simulation jobs. The effects of the three parameters, the sleeve length, the seat length and the boss height, on the electromagnetic forces and magnetic fields were researched so as to optimize the three parameters. The static and dynamic characteristics of the optimized solenoid valve were also studied. An experimental setup was established to verify the simulation results finally. Results show that the simulation values are in good agreement with the experimental values. The peak value of starting current and holding current is small and the solenoid responses rapidly. This study proves the accuracy and reliability of the simulation models and the methods. It also provides valuable references for the design and optimization of the intrinsically safe solenoid valve.
