Abstract
As we move towards more sustainable livelihood there has been a certain increment in the usage of eco-friendly transport medium. Even corporate and non-corporate organisations have started adopting non-pollutant vehicles such as bicycles, solar-powered vehicles etc. As there have been many technological advancements in the recent past even bicycles have been considered a fast and easy medium of transport thereby requiring efficient and effective safety parameters concerning structural and integral stability. As it is known that there has been a constant growth in the study of materials being used for braking applications, depending upon the economic and performance factors many investigations are ongoing in this field. Brakes play a vital role in controlling the speeding vehicles as in today’s bicycles. In order to provide a better efficient and economical braking system for bicycles, a rotor disc made of Glass Fibre Reinforced Composite (GFRC) was studied along with the conventional rotor discs. Upon testing and analysis factors affecting the performance of vehicles such as weight ratio, braking efficiency, durability, impact strength and few other material characteristics were studied for use and fabrication. GFRC was found to be a promising material to be used for the fabrication of rotor disc which is durable, efficient and economical.

Abstract
In Gas Insulated Substations (GIS), a free conducting particle can approximate any shape. If the conductor surface is not smooth and rough, then dielectric strength will be lost. So, to regain the dielectric strength, which was lost, the conductor inner surface is coated with a dielectric material of epoxy resin for which the dielectric strength can be regained. In this paper, work of simulation is done forvoltage class 132kV, 145kV,220KV and 245KVin a 1-ϕGIB for Al & Cu particles and peak radial movement was found. All the simulation analysis was carried out and resultsare shown in detail.

Published: December 2020

Abstract
Ability of multilevel inverters (MLI) to operate with matured medium power electronic devices has enhanced their prominence for active front converters in various applications such as drive control, battery energy storage systems and PV/Grid integrated systems. In short, Active front end (AFE) converters are regenerative rectifiers incorporated to, simultaneously regulate dc-link voltage and ensure unity power factor at source terminals. Realizing the significance of MLI based active front end converter, this paper presents Simulink implementation of MLI based active front end converter, using most popular classical MLI i.e., cascaded H-bridge. Imposing level shifted and phase shifted carrier arrangements, implementation PWM for CHB is demonstrated and MATLAB simulation results for both open loop and closed systems are presented.

Abstract
This study is focussed on the integration of wind farm connected through high voltagedirect current (HVDC)link in the study of load frequency control (LFC). In the study, the designed test system is an interconnected two-area multi-generating unit power system. In each area of the studied test system, the generating sources are reheating thermal, hydro, gas, nuclear generating units, and the wind farm which is connected through the HVDC system. In the study, important physical constraints which are related to system dynamics like time delay, governor dead band and generation rate constraint are considered for the effective LFC study. The primary contribution of the work is to show the impacts of a wind farms through the multi-terminal HVDC system in LFC task. The concept of inertia control and droop control of the wind farm are used in the paper for primary frequency control. For LFC model design, modified grey wolf optimizer algorithm is taken into consideration for the optimal values of proportional-integral-derivative controller gains.

Published: December 2020

Abstract
A multilevel converter can be actualized in numerous distinctive ways for a rising number of output voltage levels, increasing levels have continuously been a major inspiration within the investigate of multilevel inverters (MLI) for the reduction of total harmonic distortion (THD) with a smaller number of power devices. This paper proposes a level doubling network (LDN) and utilizes this to nearly double the number of voltage levels of a multilevel inverter topology and addition of another LDN for the development of two more output voltage level. This network sustains the merit of even loading of the distinct cell for a symmetric MLI whereas the approach is appropriate to all the existing arrangements, the unit works best for cascaded H-bridge topology, Operation of the symmetrical and unsymmetrical MLI with LDN is verified by MATLAB simulation result.

Published: December 2020

Abstract
Fly debris (FA)-is a side-effect failure extracted from coal terminated force plants by electrical / electrostatic clarifier. India does have the planet’s very largest coal reserves. In the current scenario, about 160 million tonnes of fly-debris have been produced, almost double in the last decade. A significant proportion of warm-force plants in India use bitumen and subbituminous coal and generate huge volumes of fly debris. High debris material (30 percent-half) of fossil fuels adds to these enormous fly debris volumes. Fly-debris is used in various sections such as block making, construction of streets and banks, concrete processing, agricultural uses, low-lying areas recovery, mines filling. Dust Dyke Raising the wasted enormous volume of fly debris has attracted analysts’ attention to explore new wide use techniques. Fly debris bank is one of the drive regions to mass disperse fly dust. As in India, the actual condition of street and dike fly debris use is just 6 percent. The present study refers to the potential uses as a dike material for fly debris. Fly debris does have the larger part of the important and good geophysical patent for its use as bank fill.

Published: December 2020

Abstract
Electromagnetic interference produced by high-speed electrical and electronic systems (i.e., base stations, mobile phones, radar, television and radio transmitters) that facilitate daily life also caused a pollution to be dealtwith as a part of daily life. Increasing use of electronic devices arising from the rapid developments in science and technology increased electromagnetic interference in electronic devices well besides the electromagnetic pollution in the environment. Therefore, there is a tremendous need to develop effective protection against the negative effects of electromagnetic interference. The objective of this paper is to make the composite boards from the recycling of Tetra Pak packages and to investigate the effect of aluminum additive on absorption efficiency of electromagnetic interference at various frequencies. Experimental results showed that as the ratio of aluminum additive rate in the composite material increased, the attenuation ratio increased.

Abstract
Many research works focused on using vegetable oils alone as cutting fluid and some with nanoparticles for better lubrication. But very few literature pieces are available for the use of environment-friendly nanoparticles and vegetable oils in machining. Also, the nanoparticles generally used for the research is expensive. With this paper’s help, some alternatives to conventional machining fluids are exposed through the formulation and analysis of nanofluids, which are economically feasible, effective lubricants, and environmentally friendly. For this, vegetable oils such as palm oil, peanut oil, sunflower oil, coconut oil, and castor oil are used to turn AISI 52100 (EN31) steels using tungsten carbide insert (VNMG160408) under the environment of a minimum quantity of lubrication. A newly developed environment-friendly metal cutting nanofluids of three base fluids is prepared with three zinc oxide concentrations. The most suitable nanoparticle inclusion ratio for nanofluid preparation is determined after machining at fixed levels of machining parameters.Further experiments and analyses are carried out based on Taguchi’s L9 orthogonal array to identify the appropriate cutting parameters for optimization. A considerable reduction in surface roughness and the cutting temperature are achieved using an environmentally-friendly metal cutting nanofluids instead of the base fluids. A maximum reduction in surface roughness of about 57% is obtained for EN31 using palm oil-based metal cutting nanofluids with 0.125% of the nanoparticle. About 13% drop in cutting temperature is observed using sunflower and groundnut based metal cutting nanofluids, both with 0.125% concentration. Results also indicate that the environment-friendly metal cutting nanofluids used in the experiment can replace the conventional fluids used in most metal cutting industries.

Abstract
For the design of nanostructured semiconductor solar cells and photodetectors, optics modelling can be a useful tool that reduces the need of time-consuming and costly prototyping. We compare the performance of three of the most popular numerical simulation methods for nanostructure arrays: the Fourier modal method (FMM), the finite element method (FEM) and the finite-difference time-domain (FDTD) method. The difference between the methods in computational time can be three orders of magnitude or more for a given system. The preferential method depends on the geometry of the nanostructures, the accuracy needed from the simulations, whether we are interested in the total, volume-integrated absorption or spatially resolved absorption, and whether we are interested in broadband or narrowband response. Based on our benchmarking results, we provide guidance on how to choose the method.
On a Wing and a Prayer! An Exploration of Students’ Experiences of External Supervision
Authors: Cleak Helen , Zuchowski Ines , Cleaver Mark 
Published: December 2020

Abstract
Field education is a core component of social work courses globally and has been recognised as providing significant learning opportunities to develop professional practice. Evidence highlights the strong correlation between student satisfaction with their supervisory relationship and their satisfaction with placement, but current practices have resulted in more reliance on placements with a variety of supervisory arrangements, which may be compromising a quality and supportive supervisory relationship. This article reports on an Australian online survey of 284 social work students about their experience of supervision, focusing on 119 students who received external supervision. Both quantitative ratings and qualitative comments showed that students generally described their external supervision as valuable and offered space to reflect critically on practice. Nevertheless, many felt disadvantaged without a social work presence onsite and not being observed or observing social work practice. Concerns were raised about task supervisors who offered supervision ‘on the run’ and had limited understanding of social work roles and values. Many students struggled on placement and felt that, once placement was confirmed, they received minimal support from University staff. Findings should alert field education programmes that students require consistent and ongoing involvement.
Hepatitis C Virus Transmission Among Men Who Have Sex With Men in Amsterdam: External Introductions May Complicate Microelimination Efforts

Published: December 2020

Abstract

Background
It is unclear whether unrestricted access and high uptake of direct-acting antivirals (DAAs) is sufficient to eliminate hepatitis C virus (HCV) in high-risk populations such as men who have sex with men (MSM). This study presents historic trends and current dynamics of HCV transmission among MSM in Amsterdam based on sequence data collected between 1994 and 2019.

Methods
Hypervariable region 1 sequences of 232 primary HCV infections and 56 reinfections were obtained from 244 MSM in care in Amsterdam. Maximum-likelihood phylogenies were constructed for HCV genotypes separately, and time-scaled phylogenies were constructed using a Bayesian coalescent approach. Transmission clusters were determined by Phydelity and trends in the proportion of unclustered sequences over time were evaluated using logistic regression.

Results
Seventy-six percent (218/288) of sequences were part of 21 transmission clusters and 13 transmission pairs. Transmission cluster sizes ranged from 3 to 44 sequences. Most clusters were introduced between the late 1990s and early 2010s and no new clusters were introduced after 2012. The proportion of unclustered sequences of subtype 1a, the most prevalent subtype in this population, fluctuated between 0% and 20% in 2009–2012, after which an increase occurred from 0% in 2012 to 50% in 2018.

Conclusions
The proportion of external introductions of HCV infections among MSM in Amsterdam has recently increased, coinciding with high DAA uptake. Frequent international transmission events will likely complicate local microelimination efforts. Therefore, international collaboration combined with international scale-up of prevention, testing, and treatment of HCV infections (including reinfections) is warranted, in particular for local microelimination efforts.

Published: December 2020

Abstract

Background
Rates of syphilis in the United States have more than doubled over the last several decades, largely among men who have sex with men (MSM). Our study characterizes a cluster of neurosyphilis cases among people with human immunodeficiency virus 1 (HIV-1) in Vermont in 2017–2018.

Methods
Vermont Department of Health disease intervention specialists conduct interviews with newly diagnosed HIV-1 cases and pursue sexual networking analyses. Phylogenetic and network analyses of available Vermont HIV-1 polymerase (pol) sequences identified clusters of infection. Fishers-exact and independent t-tests were used to compare people with HIV-1 within or outside an identified cluster.

Results
Between 1 January 2017 and 31 December 2018, 38 residents were diagnosed with HIV-1 infection. The mean age was 35.5 years, 79% were male and 82% were White. Risk factors for HIV-1 included MSM status (79%) and methamphetamine use (21%). Eighteen cases (49%) had HIV-1 viral loads (VLs) &gt;100 000 copies/mL and 47% had CD4 cell counts &lt;200/mm3. Eleven of the 38 (29%) had positive syphilis serology, including four (36%) with neurosyphilis. Sexual networking analysis revealed a ten-person cluster with higher VLs at diagnosis (90% with VLs &gt; 100 000 copies/mL vs 33%, P = 0.015). Phylogenetic analysis of pol sequences showed a cluster of 14 cases with sequences that shared 98%–100% HIV-1 nucleotide identity.

Conclusions
This investigation of newly infected HIV-1 cases in Vermont led to identification of a cluster that appeared more likely to have advanced HIV-1 disease and neurosyphilis, supported by phylogenetic and network analyses.

Published: December 2020

Abstract
Agricultural development is a major threat to global biodiversity, and effective conservation actions are crucial. Physiological repercussions of life alongside human-modified landscapes can undermine adaptable species’ health and population viability; however, baseline data are lacking for many wildlife species. We assessed the physiological status of a generalist carnivore, the Malay civet (Viverra tangalunga), persisting within an extensively human-modified system in Sabah, Malaysian Borneo. We characterized hematology and serum biochemistry panels from civets sampled across a mosaic landscape comprising tropical forest fragments and oil palm plantations. Intra-population variation in certain blood parameters were explained by expected biological drivers such as sex, age category and sampling season. Furthermore, we determined several erythrocyte measures, immune cell counts and dietary biochemistry markers significantly varied with proximity to oil palm plantation boundaries. These findings were supported by a case study, whereby blood profiles of GPS collared male civets were contrasted based on their exclusive use of forests or use of oil palm plantations. These data provide robust and valuable first insights into this species’ physiological status and suggest agricultural landscapes are impacting the persisting population.
Associating Site Characteristics With Distributions of Pestiferous and Predaceous Arthropods in Soybean

Published: December 2020

AbstractAlthough site-specific pest management has the potential to decrease control costs and environmental impact associated with traditional pest management tactics, the success of these programs relies on the accurate characterization of arthropod distributions within a crop. Because potential correlation of insect counts with remotely sensed field attribute data could help to decrease the costs associated with and need for fine-scale spatial sampling, we chose to determine which within-field variables would be informative of soybean arthropod counts in an attempt to move toward site-specific pest management in this crop. Two soybean fields were grid-sampled for pestiferous and predaceous arthropods, plant productivity estimates, and abiotic variable characterization in 2017–2018. Negative binomial, zero-inflated models were used to estimate presence and counts of soybean arthropod taxa based on normalized difference vegetation index (NDVI), soybean plant height, soil electrical conductivity (ECa), elevation, and calendar week. Among all variables, calendar week was the most reliable predictor of arthropod counts, as it was a significant predictor for a majority of all taxa. Additionally, counts for a majority of pestiferous taxa were significantly associated with distance from the field edge, elevation, soybean plant height, and NDVI. Although site-specific pest management has the potential for reduced management inputs and increased profitability over conventional management (i.e., whole-field) practices, management zones must first be clearly defined based on the within-field variability for the variables of interest. If site-specific pest management practices are to be applied in soybean, calendar week (and associated soybean phenology), soybean plant height (and associated elevation), and NDVI may be useful for describing the distributions of pests, such as kudzu bug, Megacopta cribraria (Hemiptera: Plataspidae) (Fabricius), green cloverworm, Hypena scabra (Lepidoptera: Erebidae) (Fabricius), velvetbean caterpillar, Anticarsia gemmatalis (Lepidoptera: Erebidae) (Hübner), and soybean looper, Chrysodeixis includens (Lepidoptera: Noctuidae) (Walker).
