Prediction of fatal accidents in Indian factories based on ARIMA
Authors: SVS Rajaprasad 
Published: April 2018

Abstract
The inherent benefits of an accident prevention program are generally known only after an accident has occurred. The purpose of implementation of the program is to minimize the number of accidents and cost of damages. Allocation of resources to implement accident prevention program is vital because it is difficult to estimate the extent of damage caused by an accident. Accurate fatal accident predictions can provide a meaningful data that can be used to implement accident prevention program in order to minimize the cost of accidents. This paper forecast the fatal accidents of factories in India by using Auto-Regressive Integrating Moving Average Method (ARIMA) model. Accident data for the available period 1980 to 2013 was collected from the Labour bureau, Government of India to analyze the long term forecasts. Different diagnostic tests are applied in order to check the adequacy of the fitted models. The results show that ARIMA (0, 0, 1) is suitable model for prediction of fatal injuries. The number of fatal accidents is forecasted for the period 2014 to 2019. These results suggest that the policy makers and the Indian labour ministry must focus attention toward increasing fatal accidents and try to find out the reasons. It is also an opportunity for the policy makers to develop policies which may help in minimizing the number fatal accidents.

Abstract
The aim of this article is to show the use of the analysis of the failure causes and effects as a prevention tool in controlling the quality of a given production process in the company. The scope of the work covers an analysis of a selected process, definition of inconsistencies present in this process, and then the FMEA analysis. In the production company one should implement thinking and actions based on the so-called ‘quality loop’ – it is an interdependence model of the undertaken actions which affect the quality shaping. It is carried out from the possibility for identifying a customer’s requirements through a project, production process, up to the assessment of effective capability for meeting the defined requirements.
The application of such an approach enables to take the actions improving the operation of quality management in a systemic way.

Published: April 2018

BACKGROUND: Early detection and prompt reporting of epidemic prone diseases (EPD’s) has been cited as the pivot in the surveillance and control of outbreaks. The contributions by clinical staff towards early detections is highly relevant, however the level of knowledge and attitude towards reporting remains unknown. The study was therefore conducted to examine the knowledge and reporting standards of clinical staff towards outbreak investigations. METHODS: A cross sectional study design was conducted in Komfo Anokye Teaching Hospital (KATH), tertiary hospital in Kumasi-Ghana between February and May 2013. Stratified, simple random sampling was used to select 111 participants and a structured questionnaire used as the instrument for data collection.RESULTS: The mean age was 31.1(±6.8) years. About 87% (n=95/111) indicated knowledge of EPD’s. More than half of these, 62.1% (n=59/95) had no idea of the definition and 30.5% (n=29/95) gave correct definition of EPD’s but had limited knowledge on the laboratory specimen required for its investigation. About 48% (n=46/95) of the respondents indicated that they would consult the nurse-in-charge of the ward instead of the public health official when an outbreak is suspected.CONCLUSION: The knowledge level of EPD’s was generally low but was found to be high with meningitis and poliomyelitis. The study has shown that the procedure for reporting EPD’s remains a challenge in the Komfo Anokye Teaching Hospital. A protocol on outbreak investigation procedures would address the gaps identified in the study.

Rabies is a source of concern for Public Health Officials. It is known to have a case fatality of 100% worldwide. Of all cases reported, 95% occurred in Africa and Asia put together. The Ghana Office of Rabies in West Africa (RIWA) suggests that the numbers in Ghana maybe underreported due to ineffective surveillance systems. The study therefore reviewed medical records of all suspected rabies cases and case-based forms filed by Disease Control Officers to the Disease Surveillance Unit of the Ghana Health Service. Twenty-one cases of suspected human rabies cases were reported in the Komfo Anokye Teaching Hospital (KATH) from January 2013 to January 2015. A little of 50% of cases were males. A third of the cases did not receive PEP though they reported to a health facility. On the average cases were reported 2 months after the exposure. This study also reported 100% fatality with 60% dying within 24 hours post admission. It is recommended that there is effort aimed at Public Education and also to control stray dogs. Governments are also admonished to make available PEPs at health facilities.

Authors: Rai Dhyanendra Bahadur 
Published: April 2018

Vegetable gardening is one of the important branches of vegetable farming in which vegetables are produced for the purpose of self-consumption and local market. In these days, the demand of fresh vegetable is increasing day by day because of rapid population growth, urbanization and growing awareness towards green vegetable in the kitchen. Hence, in the urban fringes, vegetable gardening has appeared as one of the productive enterprises for cash generation as well as self-employment. This study is completely based on primary data collected in the field by household questionnaire survey, key informants interview as well as focus group discussion (FGD). Finding clearly indicates that the cultivation of vegetable around Kirtipur area is gradually increasing and also able to fulfill few demands of vegetables in the local market of Kirtipur. This area has emerged as one of the vegetable growing pocket area among the outlying areas of Kirtipur Municipality.

The Landless Sharecroppers of Dumraha Village: A Case Study on Food Sufficiency among Tharu Community
Authors: Chaudhari Lalit 
Published: April 2018

This research analyzed the situation of sharecroppers and their food sufficiency level in forty Tharu community households in Dumraha village of Sunsari. Household interviews, focus group discussions, key informants survey and observations are led to fulfill the research objective. Among ninety-one landless sharecroppers forty households were selected for the study applying the equation. The landlessness Tharu people are compelled to do agriculture or non-agriculture labor besides farming. The Tharu communities are engaged as sharecropper to face the challenges of food self-sufficiency. Some of the sharecroppers are found to be the previous owner of the land. The practice of sharecropping is fully based on mutual relationship between landlord and sharecroppers, where they agree in sharing the output equally. Sharecropping has helped the landless Tharus to be food self sufficient. Nepalese Journal of Development and Rural StudiesVol. 14 (Joint issue) (1&2), 2017, Page: 36-42
Everyday Lives of LGBTI in Kathmandu Valley: A Narrative Inquiry
Authors: Bhatta Megh Vilas 
Published: April 2018

There is an increasing recognition of political and socio-economic right and identification of the LGBTI throughout the world. Hereby, I soaked into lived experiences of LGBTI people and interpreted those experiences for better understanding of their daily life activities, the gap between their individual identities and social identities, prevailing exclusionary provisions and need of their social inclusion in term of gender identities and social development. The study also relates to the multiple realities of the world view of LGBTI investigated through interpretive paradigms and narrative inquiry as methodology which focuses on critical life events depicted through participants’ stories, exploring their holistic views and holds valuable potential for researchers in a broad range of socio-cultural and economic structures. The research questions; how do LGBTI perform everyday life activities, how have they been appraising their identity and why social exclusionary practices have been affecting the lives of LGBTI in the development process of Nepal have been instrumental to materialize them.

Acoustic Disturbances in Galaxy Clusters
Authors: Zweibel Ellen G. , Mirnov Vladimir V. , Ruszkowski Mateusz , Reynolds Christopher S. , Yang H.-Y. Karen , Fabian Andrew C. 
Published: April 2018

Abstract
Galaxy cluster cores are pervaded by hot gas which radiates at far too high a rate to maintain any semblance of a steady state; this is referred to as the cooling flow problem. Of the many heating mechanisms that have been proposed to balance radiative cooling, one of the most attractive is the dissipation of acoustic waves generated by active galactic nuclei. Fabian et al. showed that if the waves are nearly adiabatic, wave damping due to heat conduction and viscosity must be well below standard Coulomb rates in order to allow the waves to propagate throughout the core. Because of the importance of this result, we have revisited wave dissipation under galaxy cluster conditions in a way that accounts for the self-limiting nature of dissipation by electron thermal conduction, allows the electron and ion temperature perturbations in the waves to evolve separately, and estimates kinetic effects by comparing to a semicollisionless theory. While these effects considerably enlarge the toolkit for analyzing observations of wavelike structures and developing a quantitative theory for wave heating, the drastic reduction of transport coefficients proposed in Fabian et al. remains the most viable path to acoustic wave heating of galaxy cluster cores.
A Novel Approach to Resonant Absorption of the Fast Magnetohydrodynamic Eigenmodes of a Coronal Arcade
Authors: Hindman Bradley W. , Jain Rekha 
Published: April 2018

Abstract
The arched field lines forming coronal arcades are often observed to undulate as magnetohydrodynamic waves propagate both across and along the magnetic field. These waves are most likely a combination of resonantly coupled fast magnetoacoustic waves and Alfvén waves. The coupling results in resonant absorption of the fast waves, converting fast wave energy into Alfvén waves. The fast eigenmodes of the arcade have proven difficult to compute or derive analytically, largely because of the mathematical complexity that the coupling introduces. When a traditional spectral decomposition is employed, the discrete spectrum associated with the fast eigenmodes is often subsumed into the continuous Alfvén spectrum. Thus fast eigenmodes become collective modes or quasi-modes. Here we present a spectral decomposition that treats the eigenmodes as having real frequencies but complex wavenumbers. Using this procedure we derive dispersion relations, spatial damping rates, and eigenfunctions for the resonant, fast eigenmodes of the arcade. We demonstrate that resonant absorption introduces a fast mode that would not exist otherwise. This new mode is heavily damped by resonant absorption, travelling only a few wavelengths before losing most of its energy.
Radiation-mediated Shocks in Gamma-Ray Bursts: Pair Creation
Authors: Lundman Christoffer , Beloborodov Andrei M. , Vurm Indrek 
Published: April 2018

Abstract
Relativistic sub-photospheric shocks are a possible mechanism for producing prompt gamma-ray burst (GRB) emission. Such shocks are mediated by scattering of radiation. We introduce a time-dependent, special relativistic code which dynamically couples Monte Carlo radiative transfer to the flow hydrodynamics. The code also self-consistently follows electron–positron pair production in photon–photon collisions. We use the code to simulate shocks with properties relevant to GRBs. We focus on plane-parallel solutions, which are accurate deep below the photosphere. The shock generates a power-law photon spectrum through the first-order Fermi mechanism, extending upward from the typical upstream photon energy. Strong (high Mach number) shocks produce rising νF

spectra. We observe that in non-relativistic shocks the spectrum extends to

, where v is the speed difference between the upstream and downstream. In relativistic shocks the spectrum extends to energies

where its slope softens due to Klein–Nishina effects. Shocks with Lorentz factors γ > 1.5 are prolific producers of electron–positron pairs, yielding hundreds of pairs per proton. The main effect of pairs is to reduce the shock width by a factor of

. Most pairs annihilate far downstream of the shock, and the radiation spectrum relaxes to a Wien distribution, reaching equilibrium with the plasma at a temperature determined by the shock jump conditions and the photon number per proton. We discuss the implications of our results for observations of radiation generated by sub-photospheric shocks.
On the Importance of the Nonequilibrium Ionization of Si iv and O iv and the Line of Sight in Solar Surges
Authors: Nóbrega-Siverio D. , Moreno-Insertis F. , Martínez-Sykora J. 
Published: April 2018

Abstract
Surges are ubiquitous cool ejections in the solar atmosphere that often appear associated with transient phenomena like UV bursts or coronal jets. Recent observations from the Interface Region Imaging Spectrograph show that surges, although traditionally related to chromospheric lines, can exhibit enhanced emission in Si iv with brighter spectral profiles than for the average transition region (TR). In this paper, we explain why surges are natural sites to show enhanced emissivity in TR lines. We performed 2.5D radiative-MHD numerical experiments using the Bifrost code including the nonequilibrium (NEQ) ionization of silicon and oxygen. A surge is obtained as a by-product of magnetic flux emergence; the TR enveloping the emerged domain is strongly affected by NEQ effects: assuming statistical equilibrium would produce an absence of Si iv and O iv ions in most of the region. Studying the properties of the surge plasma emitting in the Si iv λ1402.77 and O iv λ1401.16 lines, we find that (a) the timescales for the optically thin losses and heat conduction are very short, leading to departures from statistical equilibrium, and (b) the surge emits in Si iv more and has an emissivity ratio of Si iv to O iv larger than a standard TR. Using synthetic spectra, we conclude the importance of line-of-sight effects: given the involved geometry of the surge, the line of sight can cut the emitting layer at small angles and/or cross it multiple times, causing prominent, spatially intermittent brightenings in both Si iv and O iv.
Quasi-periodic Pulsations in the Most Powerful Solar Flare of Cycle 24
Authors: Kolotkov Dmitrii Y. , Pugh Chloe E. , Broomhall Anne-Marie , Nakariakov Valery M. 
Published: April 2018

Abstract
Quasi-periodic pulsations (QPPs) are common in solar flares and are now regularly observed in stellar flares. We present the detection of two different types of QPP signals in the thermal emission light curves of the X9.3-class solar flare SOL2017-09-06T12:02, which is the most powerful flare of Cycle 24. The period of the shorter-period QPP drifts from about 12 to 25 s during the flare. The observed properties of this QPP are consistent with a sausage oscillation of a plasma loop in the flaring active region. The period of the longer-period QPP is about 4 to 5 minutes. Its properties are compatible with standing slow magnetoacoustic oscillations, which are often detected in coronal loops. For both QPP signals, other mechanisms such as repetitive reconnection cannot be ruled out, however. The studied solar flare has an energy in the realm of observed stellar flares, and the fact that there is evidence of a short-period QPP signal typical of solar flares along with a long-period QPP signal more typical of stellar flares suggests that the different ranges of QPP periods typically observed in solar and stellar flares is likely due to observational constraints, and that similar physical processes may be occurring in solar and stellar flares.
An Extreme-ultraviolet Wave Generating Upward Secondary Waves in a Streamer-like Solar Structure
Authors: Zheng Ruisheng , Chen Yao , Feng Shiwei , Wang Bing , Song Hongqiang 
Published: April 2018

Abstract
Extreme-ultraviolet (EUV) waves, spectacular horizontally propagating disturbances in the low solar corona, always trigger horizontal secondary waves (SWs) when they encounter the ambient coronal structure. We present the first example of upward SWs in a streamer-like structure after the passing of an EUV wave. This event occurred on 2017 June 1. The EUV wave happened during a typical solar eruption including a filament eruption, a coronal mass ejection (CME), and a C6.6 flare. The EUV wave was associated with quasi-periodic fast propagating (QFP) wave trains and a type II radio burst that represented the existence of a coronal shock. The EUV wave had a fast initial velocity of ∼1000 km s−1, comparable to high speeds of the shock and the QFP wave trains. Intriguingly, upward SWs rose slowly (∼80 km s−1) in the streamer-like structure after the sweeping of the EUV wave. The upward SWs seemed to originate from limb brightenings that were caused by the EUV wave. All of the results show that the EUV wave is a fast-mode magnetohydrodynamic (MHD) shock wave, likely triggered by the flare impulses. We suggest that part of the EUV wave was probably trapped in the closed magnetic fields of the streamer-like structure, and upward SWs possibly resulted from the release of slow-mode trapped waves. It is believed that the interplay of the strong compression of the coronal shock and the configuration of the streamer-like structure is crucial for the formation of upward SWs.
Données administratives et évaluation des politiques régionales

Published: April 2018

L’évaluation de l’impact des politiques du travail ou concernant le capital humain se base normalement sur des enquêtes menées directement auprès des individus ayant bénéficié des dispositifs d’aides. Pour estimer leur impact net il faut en plus observer des individus non traités mais très homogènes par rapport au groupe principal. Le coût élevé de réalisation des enquêtes empêche d’augmenter la taille des échantillons et il est alors difficile de pouvoir mener des comparaisons à un niveau local. L’accès à des bases de données (fiscales, administratives, de suivi) pourrait remédier à ces limites avec beaucoup d’avantages, mais la fiabilité de cette source est souvent surestimée. Dans cet article nous présentons un travail de validation d’une base de données très complexe qui enregistre les communications ( Cob ) qui sont prévues par la loi italienne quand il y a un changement de contrat de travail. Deux sources différentes pour l’évaluation de l’impact sont comparées et discutées : la base de données des Cob et une enquête plus classique.	Classification JEL : C55, C81, P46 ; J08
