As Mobile Ad hoc Networks (MANETs) are established using battery-powered nodes, the major concern to minimize the power consumption of the nodes is still a challenge while the lifetime of the network is taken into account. Thus, power-aware routing is the effective way to handle the situation that aims at minimizing the power consumption and network overhead in order to increase the network lifespan. Therefore, an effective power-aware secure routing protocol is designed using the proposed Fuzzy Krill Herd-based Grasshopper Optimization Algorithm (Fuzzy KH-GOA) such that the secure path is determined. Hence, it is evident that the routing path for transmitting the data packets is effectively decided using the proposed algorithm, which is based on the fitness parameters, such as fuzzy function, delay, distance, and power consumed by the path. The significance of this research relies on the link lifetime estimation for which the lifetime of the routes is detected in order to measure the link failure. The performance of the proposed Fuzzy KH-GOA reported the values of 23.858 J, 0.016 sec, 0.783, 0.840, and 10.908 sec, respectively in the absence of the attack and 22.624J, 22.624sec, 0.773, 0.812, and 9.862sec, respectively in the presence of attack for the measures, such as power, delay, Detection Rate (DR), throughput, and average Link Life Time.

Antenna arrays are prominently used in satellites, radars mobile and wireless communication systems. Design of an antenna array with minimum side projections is the crucial component for noise free communications. There are various nature inspired optimization method have been suggested to optimize the peak side projections. To overcome low solution accuracy and low convergence rate, we are using newly developed Cauchy mutated invasive and optimization (CMIWO) to minimize the peak side projection levels in the radiation pattern. CMIWO is adapted to reduce the amplitude of the each antenna element. We have used 24, 32, and 64 element linear array of antenna for the synthesis. Based on the results the CMIWO produces suggestive reduction in peak side projections when contrasted with other array of antennas.

Data Mining plays an important role in the Business world and it helps the educational institution to predict and make decisions related to the students’ academic status. From a large volume of data in educational databases it is difficult to predict student performance. In India currently the existing systems lack in monitoring and analyzing the students’ performance. The main reason is that the existing system has insufficient capabilities for identification of performance of the student and it also not considered all factors that affect the achievements of a student’s in the context of India. Therefore, a systematical literature review on predicting student performance by the proposed system is a web-based which makes use of the mining techniques for the extraction of useful information. This work is digging insight into the state-based and event-based approaches for predicting student performance. A Comparative analysis is conducted to suggest regression-based algorithms of state-based framework lack accuracy and correlation-based algorithms under the event-driven approach outperform classical regression algorithms. It is also concluded from pedagogical a point of view, higher engagement with social media leads to higher final grades.

The use of absorbent materials such as fibrous materials is considered as an innovative solution to solve noise problems. The purpose of this research paper is to study the acoustic absorption of a new bio-sourced fibrous material called "Alfa fibers", in order to use it as an absorbent material to reduce reverberation time in the building construction domain (theatre, cinema, conference room, ...). For that, a set of 36 samples was designed and prepared for different thicknesses and different densities in order to evaluate the effect of thickness variation and density variation on sound absorption performance. An experimental study was carried out to measure the sound absorption coefficient at normal incidence, using the ISO 10534-2 standard method known as two-microphone transfer function method. All tests were performed in a Kundt tube with a diameter of 10 cm, in the frequency range (50-1600 Hz). These measurements show that the absorption coefficient can reach a value of 0.9 around 1000 Hz. The experimental results clearly show that sound absorption improves when the thickness of the samples increases, or when the density increases to an optimal value of 300Kg/m3 from which absorption performance begins to decrease. At low frequencies, sound absorption can be improved by creating an air gap between the sample and the rigid bottom.

The research work was carried out to investigate the behaviour of bituminous concrete mix with addition of waste plastic bottles made up of Polyethylene Terephthalate (PET) via dry process. Marshall moulds were prepared with bitumen content 5.0 to 5.8% (with 0.2% increment) and waste plastic content 0%, 4%, 6%, 8%, 10%, 12% and 14 % by weight of bitumen. Mechanical properties required for an ideal mix were determined. Results show that with increase in quantity of PET, mechanical properties of bituminous concrete mixes improve initially up to certain extent. The optimum bitumen content for conventional mixes was found to be 5.66%. Modified mix of 8% PET content with 5.40% bitumen content fulfils the requirements of modified mixes as per IRC SP-98, 2013 specifications. Bitumen content reduced to be 4.59% with addition of waste plastic bottle in bituminous concrete mixes. Hence, application of plastic waste in bituminous pavements is environmental friendly solution in terms of disposal of non-biodegradable waste plastic along with improvement in mechanical properties of bituminous mixes.

This paper concentrates on the design of DC multiplier for solar photovoltaic application. The main aim of this paper is to boost up the voltage from solar panel without using transformer and to track maximum power using maximum power point algorithm. The system design includes solar panel, snubber circuit, switching circuit, coupled inductor, opto isolator, voltage multiplier, microcontroller and load. Normally boost converter is used in conjunction with solar PV to boost the output voltage from panel. But the boost converter can be able to increase the input voltage to a limited value. In other, converter transformers are used. Hence core loss, magnetic loss and copper loss will occur. To overcome these losses and also to achieve isolation coupled inductor can be used. Thus proposed system overcomes the core loss, magnetic loss, copper loss and also helps to achieve the isolation between the circuits by using the coupled inductor. By using voltage multiplier, the boost converter can able to increase the input voltage beyond the rated value. Simulations are done in MATLAB/Simulink platform. It forms the voltage multiplier for renewable energy application to boost the DC voltage.

Mathematical analysis and stability prediction of soft switched isolated dc-dc converter is presented in this paper. Half bridge dc-dc converter is an attractive topology for low voltage applications due to its simplicity, lower cost, improved reliability and enhanced dynamic performance. Both power semiconductor switches of the proposed isolated converter operate asymmetrically under Zero Voltage Switching (ZVS) to achieve high efficiency and low voltage stress. Furthermore, the ringing resulted from the oscillation between the transformer leakage inductance and the junction capacitance of two switches is eliminated. Conversion efficiency is also improved by providing synchronous rectifier with very small output filter. The operating principle, state space analysis and control strategy of proposed converter is explained with small signal model. Experimental results are presented to explain the zero voltage switching capability and stability features of proposed converter.

Historical growth for development of power to fulfil the demands, together provides a challenge for depletion of fossil fuels. The internal combustion engines have a major share used to develop power. To fulfil the increasing demands, many researchers worked on diesel engine with biodiesel blends derived from edible and non-edible oils as an alternative fuel. Some researcher’s experimented gaseous fuels along with diesel also in which diesel will be primary fuel and gaseous fuels like acetylene will be secondary fuel. Increased rates of pollutants again required more focus in modification of engine sub-assemblies. The present study carried out to find the cost effectiveness while the constant speed diesel engine supplied 2 liter per minute flow rate of acetylene at different compression ratios. It realized that the brake specific fuel consumption and required cost to operate the engine, in case of duel fuel mode operation will be less for the compression ratio of 17. It was also noted that for idling or low load the operation of engine will be costly with duel fuel mode of operation and for maximum load the cost of operation will be barely same as the operation on only diesel. The results from performance analysis states that in duel fuel mode of operation by decreasing compression ratio to 17, no change in power out with decreased sound pressure. Also from emission analysis decreased CO2, HC emission found than only diesel operation.

On the Rate of Neutron Star Binary Mergers from Globular Clusters

Published: December 2019

The first detection of gravitational waves from a neutron star–neutron star (NS–NS) merger, GW170817, and the increasing number of observations of short gamma-ray bursts have greatly motivated studies of the origins of NS–NS and neutron star–black hole (NS–BH) binaries. We calculate the merger rates of NS–NS and NS–BH binaries from globular clusters (GCs) using realistic GC simulations with the CMC Cluster Catalog. We use a large sample of models with a range of initial numbers of stars, metallicities, virial radii, and galactocentric distances, representative of the present-day Milky Way GCs, to quantify the inspiral times and volumetric merger rates as a function of redshift, both inside and ejected from clusters. We find that over the complete lifetime of most GCs, stellar BHs dominate the cluster cores and prevent the mass segregation of NSs, thereby reducing the dynamical interaction rates of NSs so that at most a few NS binary mergers are ever produced. We estimate the merger rate in the local universe to be ∼0.02 Gpc−3 yr−1 for both NS–NS and NS–BH binaries, or a total of ∼0.04 Gpc−3 yr−1 for both populations. These rates are about 5 orders of magnitude below the current empirical merger rate from the Laser Interferometer Gravitational-Wave Observatory/Virgo. We conclude that dynamical interactions in GCs do not play a significant role in enhancing the NS–NS and NS–BH merger rates.

Authors: Drenska Maria , Elitova Savina , Grigorova Velina , Naseva Emilia , Getov Ilko
Published: December 2019

Introduction: The off-label use of medicines is a common practice that covers a wide range of therapeutic areas in both, adults and children. So far, the extent of off-label use among neurology patients in Bulgaria has not been studied. The aim of this study is to provide data on the off-label use in neurology patients in Bulgaria and to contribute to planning actions by the European Commission and EMA to provide a harmonized guideline and to regulate the off-label use of medicines within the European Union.

Materials and methods: The data on prescriptions of 360 neurology outpatients, treated in a 1 – year period, were recorded and provided for analyses. The Summaries of Product Characteristics, were used as reference documents for assessment of prescriptions.

Results: The results from this study show that most neurology patients (63%) were exposed to off-label use. Most of the medicines prescribed off-label (90%), were used for a therapeutic indication, other than the one listed in the authorized product information. Meloxicam is found to be the most commonly prescribed off-label medicine. Other medicines, like trasadone, pentoxyfylline and fupentixol / melitracen were prescribed less frequently, but deserve special attention, as they were found to be used off-label to a very large extent, some of them in 100% of prescriptions. Half of the top 10 medications, most commonly used off-label in neurology, were found to be non-steroidal anti-inflammatory drugs.

Conclusion: The results reveal a big gap between the authorized medicines and the real medical needs. Further studies based on a larger number of medical centers are needed to establish more accurate data on off-label prescribing in neurology patients on a national level.

Borders within. An Ethnographic Take on the Reception Policies of Asylum Seekers in Alto Adige/South Tyrol
Authors: degli Uberti Stefano
Published: December 2019

The “processual turn” in the study of borders has opened up to the analysis of how borders and border regimes, conceived of as social practices, are created/recreated in many ways, for many actors, at any place and time; however, this perspective still coexists with traditional approaches to borders, characterized by a fixation with the notion of border only as a tangible entity, the physical outcome of political, social and/or economic processes. These studies develop through sophisticated and erudite conceptual analysis, not always balanced by equal empirical anchorage. Conversely, based on an ethnographic account of asylum seekers’ reception policies in Alto Adige/Südtirol, the article empirically frames the concept of “border” by retracing the experiences of the so-called “out-of-quota” asylum seekers (profughi fuori quota/Asylbewerber fuori quota) in light of their categorization prompted by local policy and media discourses. The author unveils the performative dimension of labelling practices by arguing that these not only fuel misrepresentation but translate into bordering practices that exacerbate juridical and social vulnerability and hinder access to reception facilities and welfare services.
“To Own or Not to Own”. Post-socialist Housing Policy, Privatism and Regimes of Vulnerability in Prague, Czech Republic
Authors: Lehečka Michal
Published: December 2019

In the course of 2016, housing prices in Prague started to grow rapidly, as a result of long-term pressure generated by stagnation of construction industry, a constant influx of newcomers, speculations, shared economy platforms, etc. These globally embedded processes brought to light almost forgotten urban vulnerables: the non-owners. Prague’s current housing situation emerged from the post-socialist way of ownership liberalization and deregulation, often labelled as a regime of privatism (Hirt 2012). After the 40-year period of state-driven socialist ownership, 1990’s and 2000’s privatization transformed approx. 90% of housing stock into private property. Private ownership was thus rediscovered as a component of social status while simultaneously both city and the state abandoned any pro-active housing policy. Based on fieldwork conducted on peripheries of Prague, my paper focuses on various forms of housing vulnerability in Prague. A situation of non-owners, who have to cope with danger of displacement, will be confronted with the strategies and practices of the “newcomers” – post-Soviet region immigrants who are moving in and buying apartments in similar suburban housing estates. Examined through individual spatialities, temporalities, and hybrid regimes of in/out and local/global the paper will discuss the post-socialist housing market.

This chapter reviews several components of five certification schemes: 1) pre-requisites, 2) knowledge areas, 3) skills areas, 4) language combinations, and 5) certification maintenance. The comparisons reveal similar approaches to interpreter certification with a few significant variations. These common elements form the basis for a substantive international equivalence and comparability. At a closer look, each scheme reveals different solutions to the shared challenges. This chapter ends with recommendations for any ongoing or future interpreter certification program and for interpreting stakeholders.
Interpreting and the Mental Status Exam
Authors: Fox Meghan L. , Pollard Jr. Robert Q
Published: December 2019

The necessity of engaging qualified interpreters to work in partnership with mental health clinicians when serving patients with a limited English proficiency (LEP) is gaining widespread support. Numerous research studies have documented improved patient health and satisfaction outcomes in this regard. Psychiatric practice often involves complexities of thought, language, and communication that clinicians and interpreters must appreciate. One such topic is engaging LEP patients in the mental status examination (MSE). This chapter describes the nature of the MSE, challenges when interpreting for the MSE, strategies for handling such challenges, and approaches for effective collaboration between interpreters and mental health clinicians regarding the MSE and cross-linguistic mental health care more broadly. The current state of scholarship in the field of mental health interpreting and training opportunities for interpreters who seek to improve their knowledge and skills in the mental health arena also are discussed.

With the developing complexity of international communication and the development of hospitals, diversified interpreting demands, such as interpreting for conferences held by hospitals and for visiting delegations from overseas healthcare institutions, have emerged in the medical field, other than interpreting in the clinical setting. Instead of engaging a professional interpreter temporarily, many hospitals are more inclined to invite their own staff to interpret, for many reasons. The core issue is to empower the medical staff with interpreting competence. This chapter examines a case study closely to summarize and share the teaching experience for training conference-level dual-role interpreters in the medical field. The research then proposes the competence-oriented task-based learning approach and examines its effectiveness.
In Through the Looking Glass
Authors: Sasso Angela
Published: December 2019

Traditional interpreter education programs were designed for conference interpreting markets. With the introduction of dialogue interpreting, some portion of the educational content was then allotted to public service interpreting and specialized settings became more prominent, programs then added courses to place more attention on specific contexts. In the last decade researchers began to view healthcare interpreting as a specialization of interpreting, and not just interpreting in a different setting. This chapter will review the evolution of the healthcare interpreter's role in the context of alignment between education and workplace reality in Canada. The results of this review demonstrate that the work expectations of healthcare interpreters do not align with delineations of the interpreter as a language conduit nor with current educational programs and recommends a more robust and situated pedagogical schema that includes ongoing and deliberate continuing education as an interim measure to mitigate tensions between student and practitioner, theory and practice.
Three-Dimensional Optical Scanning in Post–kala-azar Dermal Leishmaniasis (PKDL)

Published: December 2019

Post–kala-azar dermal leishmaniasis may occur after successful treatment of visceral leishmaniasis and is characterized by macules, papules, or nodules in the skin, with varying size. The response to antileishmanial therapy remains difficult to assess because there are presently no reliable biomarkers. To date, skin lesions are clinically assessed for decrease in size or change in color, which is invariably subjective. Novel 3-dimensional optical scanning devices offer safe and field-adapted methods to objectively assess skin lesions for changes over time in size and color that can be quantified with great accuracy.

Pharyngitis is usually caused by a viral infection for which antibiotics are often unnecessarily prescribed, adding to the burden of antimicrobial resistance. Identifying who needs antibiotics is challenging; microbiological confirmation and clinical scores are used but have limitations. In a cross-sectional study nested within a randomized controlled trial, we estimated the prevalence and antibiotic susceptibility profiles of group A Streptococcus (GAS) in patients presenting to primary care with a sore throat and fever in northern Thailand. We then evaluated the use of C-reactive protein (CRP) and clinical scores (Centor and FeverPAIN) to identify the presence of GAS. One hundred sixty-nine patients were enrolled, of whom 35 (20.7%) had β-hemolytic Streptococci (BHS) isolated from throat swab culture, and 11 (6.5%) had GAS. All GAS isolates were sensitive to penicillin G. The median CRP of those without BHS isolation was 10 mg/L (interquartile range [IQR] ≤ 8–18), compared with 18 mg/L (IQR 9–71, P = 0.0302) for those with GAS and 14 mg/L (IQR ≤ 8–38, P = 0.0516) for those with any BHS isolated. However, there were no significant relationships between CRP > 8 mg/L (P = 0.112), Centor ≥ 3 (P = 0.212), and FeverPAIN ≥ 4 (P = 1.000), and the diagnosis of GAS compared with no BHS isolation. Identifying who requires antibiotics for pharyngitis remains challenging and necessitates further larger studies. C-reactive protein testing alone, although imperfect, can reduce prescribing compared with routine care. Targeted CRP testing through clinical scoring may be the most cost-effective approach to ruling out GAS infection.

Environmental enteric dysfunction (EED) may be ameliorated by zinc supplementation. The objective of this study was to investigate the impact of different forms of zinc supplementation on biomarkers of EED (i.e., plasma citrulline, kynurenine, and tryptophan concentrations and the kynurenine:tryptophan [KT] ratio) among young Laotian children. In a double-blind randomized controlled trial, 3,407 children aged 6–23 months were randomized into one of four groups: daily preventive zinc dispersible tablets (PZ; 7 mg zinc), daily multiple micronutrient powders (MNP; 10 mg zinc, 6 mg iron, and 13 other micronutrients), therapeutic zinc supplements for diarrhea treatment (TZ; 20 mg/day for 10 days), or daily placebo powder, and followed up for ∼36 weeks. Plasma samples at baseline and endline for 359 children were analyzed for citrulline, kynurenine, and tryptophan concentrations. At baseline, the prevalence of stunting and zinc deficiency was 37% and 76.5%, respectively. The mean plasma citrulline, kynurenine, and tryptophan concentrations were 24.6 ± 5.4 µmol/L, 3.27 ± 0.83 µmol/L, and 72.3 ± 12.9 µmol/L, respectively; the mean KT ratio (×1,000) was 45.9 ± 12.0. At endline, neither plasma citrulline, kynurenine, or tryptophan concentrations, nor the KT ratio differed among intervention groups (P > 0.05). In this population, PZ, MNP, and TZ had no overall effect on plasma concentrations of citrulline, kynurenine, and tryptophan, or the KT ratio. The need remains to better understand the etiology of EED, and the development of biomarkers to diagnose EED and evaluate the impact of interventions.

Schistosomiasis control programs rely heavily on mass drug administration (MDA) campaigns with praziquantel for preventative chemotherapy. Areas where the prevalence and/or intensity of schistosomiasis infection remains high even after several rounds of treatment, termed “persistent hotspots” (PHSs), have been identified in trials of MDA effectiveness conducted by the Schistosomiasis Consortium for Operational Research and Evaluation (SCORE) in Kenya, Mozambique, Tanzania, and Côte d’Ivoire. In this analysis, we apply a previously developed set of criteria to classify the PHS status of 531 study villages from five SCORE trials. We then fit logistic regression models to data from SCORE and publically available georeferenced datasets to evaluate the influence of local environmental and population features, pre-intervention infection burden, and treatment scheduling on PHS status in each trial. The frequency of PHS in individual trials ranged from 35.3% to 71.6% in study villages. Significant relationships between PHS status and MDA frequency, distance to freshwater, rainfall, baseline schistosomiasis burden, elevation, land cover type, and village remoteness were each observed in at least one trial, although the strength and direction of these relationships was not always consistent among study sites. These findings suggest that PHSs are driven in part by environmental conditions that modify the risk and frequency of reinfection.
