AbstractThe HPTN 071(PopART) study was a community-randomised trial in Zambia and
South Africa, examining the impact of combination-prevention including universal
testing and treatment (UTT), on HIV-incidence. This sub-study evaluated factors
associated with IPV (physical and/or sexual) to identify differences by HIV status.
During 2015–16, a random subset of adults who participated in the first year of the
PopART intervention were recruited and standardised questionnaires were
administered. Logistic regression was performed to estimate odds ratios of factors associated with IPV. Among > 700 women studied (300 HIV-negative;400 HIV-positive),
~ 20% reported experiencing physical and/or sexual violence in the last 12-months.
Sexual violence was similar by HIV status, but physical violence and reporting both
physical/sexual violence was more common among HIV-positive women. Spending
nights away from the community in the last 12-months was associated with higher odds
of IPV among both HIV-negative (aOR 3.17, 95% CI 1.02–9.81) and HIV-positive women
(aOR 1.79, 95% CI 0.99–3.24). Among HIV-positive women, financial autonomy was
associated with reduced IPV (aOR:0.41,95%CI:0.23-0.75) while pregnancy in the last
12-months (aOR 2.25, 95% CI 1.07–4.74), risk of alcohol dependence
(aOR 2.75, 95% CI 1.51–5.00) and risk of mental distress (aOR 2.62, 95% CI 1.33–5.16)
were associated with increased IPV. Among HIV-negative women reporting sex in the
last 12-months, transactional sex (aOR 3.97, 95% CI 1.02–15.37) and not knowing
partner’s HIV status (aOR 3.01, 95% CI 1.24–7.29) were associated with IPV. IPV was
commonly reported in the study population and factors associated with IPV differed by
HIV status. The association of mobility with IPV warrants further research. The high
prevalence of harmful alcohol use and mental distress, and their association with IPV
among HIV-positive women require urgent attention.

Published: February 2022

AbstractWith the continued proliferation of digitized materials, critical attention to the ideologies informing the creation of digital archives remains crucial. How are digital archives made and what are their goals? How do different participants in the process work together in collaborative teams towards shared ideals? This paper outlines the methodological and political considerations that underlie the creation of a critical digital archive of historical and born-digital materials relating to 20th-century publishing history,The Modernist Archives Publishing Project(MAPP). Here we outline the archival practices and critical ethos that have informed the collaborative creation ofMAPPby an international team of scholars, archivists, cultural institutions, students, and copyright estate holders. We address issues of selection that arise in creating a critical digital archive; feminist critical metadata practices; and our approaches to workflow and copyright; and conclude with an example of an archival document type in which the issues of feminist critical curation and copyright collide.
PRESSAFE-disp: a method for the fast in-plane seismic assessment of existing precast RC buildings after the Emilia earthquake of May 2012
Authors: Bovo Marco , Praticò Lucia , Savoia Marco 
Published: February 2022

AbstractThe existing precast reinforced concrete structures not specifically designed against earthquakes have proved to be very sensitive to seismic demands. After the lesson learnt from the Emilia earthquake of May 2012, causing many collapses and severe damage, reliable seismic design criteria have been established for the design of new precast structures and for the strengthening of the existing ones. Despite this, a large percentage of the existing precast buildings in the Italian territories actually has not been object of interventions and remains in an unsafe condition with regard to the seismic actions. In this context, the methods for a rapid seismic assessment can be very helpful both to estimate the current safety level of large building stocks and to plan the necessary strengthening interventions, possibly at the large scale of an industrial area. To this aim, the paper proposes the PRESSAFE-disp (PRecast Existing Structure Seismic Assessment by Fast Evaluation-displacements) method, useful for the fast evaluation of the fragility curves of precast structures. The damage criteria, applicable both to structural elements and non-structural cladding elements on the perimeter, have been selected in order to capture the damage mechanisms observed during the building inspections conducted by the authors in the aftermath of the 2012 Emilia earthquakes. The method allows a comprehensive explanation of the seismic in-plane behaviour of existing precast RC buildings and could be effectively adopted, for example, in earthquake loss estimations and seismic risk assessments of large Italian industrial areas, as well as of wide seismic-prone territories of the Mediterranean area.

AbstractThe recommendation systems plays an important role in today’s life as it assist in reliable selection of common utilities. The code recommendation system is being used by the code databases (GitHub, source frog etc.) aiming to recommend the more appropriate code to the users. There are several factors that could negatively impact the performance of code recommendation systems (CRS). This study aims to empirically explore the challenges that could have critical impact on the performance of the CRS. Using systematic literature review and questionnaire survey approaches, 19 challenges were identified. Secondly, the investigated challenges were further prioritized using fuzzy-AHP analysis. The identification of challenges, their categorization and the fuzzy-AHP analysis provides the prioritization-based taxonomy of explored challenges. The study findings will assist the real-world industry experts and to academic researchers to improve and develop the new techniques for the improvement of CRS.

Published: February 2022

AbstractIn this study, simulation and experimental methods were used to investigate the influence of cold spray conditions on AISI 316L stainless steel coatings. The effect of both helium and nitrogen gases used was investigated. The temperature, particle sizes of spraying powder, and distance from the nozzle throat to the impinging point were estimated by using the Kinetics Spray Solutions GmbH software. The 316L stainless steel (SS) coatings were examined by X-ray diffraction, Scanning Electron Microscopy and Energy Dispersive X-Ray Microanalysis. The tribological behavior was evaluated under different loads (2 N and 5 N) in dry conditions. It was found that the nitrogen and helium propellant gas with high speed and fine particles led to produce good coatings with dense microstructures. From the nanoindentation experiments, the Young's modulus and hardness of the SS 316L samples were enhanced of about 8% with helium due to the high particle velocity. It was shown that the wear resistance of SS 316L produced with helium was higher than that of the standard SS 316L coatings. The coatings produced with helium revealed lower friction coefficient (0.65) and wear rate (6.9 × 10–4 mm3/Nm) under 2 N applied load than that obtained nitrogen. It was also found that the SS 316L cold sprayed by helium with dense structure presents high hardness and good tribological performance that can be suggested for several applications.

Can Gestures Give us Access to Thought? A Systematic Literature Review on the Role of Co-thought and Co-speech Gestures in Children with Intellectual Disabilities
Authors: Lacombe Noémie , Dias Thierry , Petitpierre Geneviève 
Published: February 2022

AbstractThis systematic review analyzes the differential use of gestures in learning by children with intellectual disability (ID) compared to typically developing ones (TD). Eleven studies published between 2000 and 2020 fulfilled the inclusion criteria (N = 364 participants). The results identify three key elements: (1) Children with ID accompany their spoken language with more gestures than TD children; (2) Specifically, they produce more iconic gestures that provide access to the conceptualization process and understanding in students with ID; (3) Children with ID rely on gesture more than TD children to carry meaning (i.e., produce unimodal gestural utterances without accompanying speech). Possible implications for teaching and guidelines for future research are proposed.
Are we free to make the laws?
Authors: Loew Christian , Hüttemann Andreas 
Published: February 2022

AbstractHumeans about laws maintain that laws of nature are nothing over and above the complete distribution of non-modal, categorical properties in spacetime. ‘Humean compatibilists’ argue that if Humeanism about laws is true, then agents in a deterministic world can do otherwise than they are lawfully determined to do because of the distinctive nature of Humean laws. More specifically, they reject a central premise of the Consequence argument by maintaining that deterministic laws of nature are ‘up to us’. In this paper, we present a new argument for Humean compatibilism. We argue that Humeans about laws indeed have resources for defending compatibilism that non-Humeans lack (though not for the reasons typically discussed in the literature). Moreover, we show that utilizing these resources does not lead to objectionable consequences. Humeans about laws should thus embrace Humean compatibilism.
Physical analysis of the environmental impacts of fishery complementary photovoltaic power plant

Published: February 2022

AbstractPhotovoltaic (PV) power plants have shown rapid development in the renewable sector, but the research areas have mainly included land installations, and the study of fishery complementary photovoltaic (FPV) power plants has been comparatively less. Moreover, the mechanism of local microclimate changes caused by FPV panels has not been reported. This work revealed this mechanism using a physical model to illustrate the impact of FPV power plants in a lake on the environment. The results indicated that the lake becomes a heat sink after deploying the PV panel on water. The comprehensive albedo (0.082) decreased by 18.8% relative to the free water surface (0.101). The water energy change was dominated by the water–air vapor pressure deficit. In addition, the FPV panels had a heating effect on the ambient environment; however, the range of this effect was related to the water depth. The installation had an obvious heating effect on surface water.
Sequential stress control and delayed support in deep shaft construction

Published: February 2022

AbstractIn constructing hard rock mine deep shafts, the failure caused by high stress is a significant problem. A construction section extending from the -930 m to -1271 m level of a 1527 m deep shaft was selected as a case study. Q, RMR, and GSI rock mass quality classifications of the surrounding rock were obtained to determine the shaft’s maximum unsupported sinking cycle height in different construction sections. The potential failure mode, failure zone shape, and failure depth of the surrounding rock shaft under high stress were then analyzed theoretically, empirically, and by numerical simulation, sequential stress control and delayed support technology was proposed according to the results. The temporary and permanent support timing parameters were calculated and verified by the empirical chart, numerical simulation, convergence-confinement theory, and theoretical formula. Results show that the surrounding rock in all the construction sections from -930 m to -1271 m belongs to the mild or severely pressure squeezed strata. The potential failure mode is stress-controlled, and the failure zone of the surrounding rock is “ear” shaped. Temporary support strengthens the rock mass, improves the shear capacity of surrounding rock, and prevents the broken rock from falling but does not release stress. Permanent support, conversely, cannot bear the stress of surrounding rock. The stress and elastic strain energy in rock mass should be released to the greatest extent possible before installing permanent support; it is not advisable to install it too early. The time and cycle height of delayed permanent shaft support were comprehensively determined to be four days and 16 m, respectively. The numerical simulation and safety factor proof show that the sequential stress control process effectively minimizes stress in surrounding rock and ensures long-term shaft stability.

Abstract
The Palaeoproterozoic eastern Mahakoshal belt of Central India Tectonic Zone (CITZ) is known for gold occurrences. Gold occurs predominantly in quartz veins and quartz-carbonate veins. It is associated with pyrite, pyrrhotite and arsenopyrite mineral assemblages. The secondary alteration products such as ‘scorodite’ and ‘mansfieldite’ are also associated with gold mineralisation. Recent investigations carried out in Parsoi area, have indicated the association of gold with bismuth, bismuthinite and telluride. This is the first record of bismuth from the Mahakoshal belt. The studies of the bismuth tellurides contribute to the assessment and evaluation of concentrations of gold resources.
Importance of Fracturing Hard and Massive Overlying Strata for Complete Extraction of Thick Coal Seam – Case Studies

Published: February 2022

Abstract
Engineering efforts need to be organized as per the rock mechanic conditions of the site for efficient underground extraction of a thick coal seam. Geo-mining conditions of Indian coalfields have favoured development of thick coal seams on Bord and Pillar (B&P) method, where single lift depillaring of total thickness (SLDTT) is vital for their final extraction. Competency of heightened pillar is an important factor for uncontrolled roof-pillar interaction during caving of the hard and massive overlying strata. An increase in extraction height by underwinning of roof coal band of the thick coal seam during retreat, developed along its floor horizon, is found to be the main reason for the strength deterioration. Conducted field studies also showed that the presence of competent overlying strata caused caving after a large overhang inside the goaf varying from 6000 m2 to 12500 m2. An attempt was made to control the roof caving by a proportional increase in width of the heightened pillars and it worked well but caused the issue of resource conservation. However, another field study with SLDTT working below laminated and weak overlying strata experienced a smooth strata control condition. This fortifies the idea of strength reduction of the competent overlying strata by fracturing for a controlled strata behaviour. This paper presents the result of the field investigations to demonstrate the role of strength reduction of overlying strata for underground extraction of total thickness of a thick coal seam in single lift.
The Effect of Discontinuity Orientation and Thickness of the Weathered Layer on the Stability of Lesser Himalayan Rock Slope
Authors: Ray Arunava , Rai Rajesh , Singh T. N. 
Published: February 2022

Abstract
The effect of discontinuity orientations and thickness of the weathered layer in the stability of jointed phyllite rock slopes of the Lesser Himalayan region was examined in this study. Numerical simulation was performed using the Rocscience RS2 V9 finite element software package. The performance of the slope was assessed for varying slope height, slope angle, weathered layer thickness, and orientation of the main joint and the cross joint set. The results indicate that the stability of rock slope depends on the relative orientation and distribution of the contained joint sets and the thickness of the weathered layer. Based on numerical simulation, the order of percentage reduction of a factor of safety (FOS) for the critical combination of joint sets has been identified. It was deduced that while keeping all the parameters constant, the effect of cross joint orientations is prominent in the case of shallow weathered layer and reduces as the thickness of the weathered layer increases. The effect of main joint orientations is prominent in the case of a deep weathered layer and reduces as the thickness of the weathered layer decreases. Analysis of variance (ANOVA) of the obtained result indicates that all the independent variables (slope height, slope angle, weathered layer thickness, main joint set, and cross joint set) are significantly predicting the dependent variable (FOS of rock slope) and the reducing order of significance is weathered layer thickness, slope angle, main joint orientation, slope height, and cross joint orientation.

Published: February 2022

AbstractThe toxicity of heavy metals in the aquatic environment is a serious challenge to the global community. Even at low concentrations, heavy metals have a cumulatively destructive effect on living organisms in the aquatic environment. Biomass wastes have been investigated for heavy metals removal in the published literature; however, the low performance and capacity of the biomass represents a drawback towards effective application. Therefore, in this study, biomass waste such as corn leaves that have low cost is investigated as a precursor for eco-friendly sustainable nanostructured composite. In this research, several experiments have been conducted focusing on upgrading the capacity of the bioresource for removing heavy metals from the aquatic environment. In addition to low-cost biomass material, nanomaterials such as zinc oxide represents an attractive combination for effective removing heavy metals such as iron and nickel ions. Characterization of the synthesized composite material was conducted using XRD–FESEM-mapping and EDX–HRTEM and SAED–Zeta size and Zeta potential. Moreover, studying the efficiency of synthesized nano-composite for heavy metals ions adsorption of iron and nickel ions shows an outstanding increase of performance. The results suggest that adding nanomaterial to biomass matter and obtaining a composite at nanosize, enables the increase of the adsorption efficiency of heavy metals.
Investigation of transonic aerodynamics on a triple-delta wing in side slip conditions

Published: February 2022

AbstractThe vortex-dominated flow around the triple-delta wing ADS-NA2-W1 aircraft is investigated in order to achieve a better understanding of the flow physics phenomena that occur over the aircraft particularly at the transonic speed condition. Both URANS and scale-resolving DDES have been employed in order to explore the range of suitability of current CFD methods. The Spalart–Allmaras One-Equation Model with corrections for negative turbulent viscosity and Rotation/Curvature (SA-negRC) is employed to close the RANS equations, whereas the SAneg-based DDES model is applied in the scale-resolving computations. The DLR TAU-Code is used to perform the numerical simulations. The deficiencies of the URANS results are illustrated and promising improvements are reached employing the SAneg-DDES numerical method. The hybrid method results show great advancement in the prediction of the multiple-delta wing flow by revealing physical aspects which have not been seen from URANS with sufficient accuracy like vortex–vortex interaction and shock-vortex interaction. These phenomena furthermore explain in a clear way the improved prediction of the surface pressure coefficient over the aircraft and consequently of the aerodynamic force and moment coefficients.

Authors: Huijben Manou , Lock M. W. T. Tycho 
Published: February 2022

SamenvattingHypogonadisme is een wereldwijd probleem onder mannen dat seksuele, fysieke en mentale problemen veroorzaakt. Clomifeencitraat (CC) is een alternatieve, offlabel therapie, vooral voor mannen met een actieve of toekomstige kinderwens. In deze single-centerstudie werden 153 mannen die behandeld werden met CC voor hypogonadisme retrospectief geëvalueerd. Uitkomstmaten waren onder andere hormonale evaluatie, hypogonadale symptomen, metabole en lipidenparameters, veiligheidsaspecten en bijwerkingen. Tijdens de behandeling nam het totaal testosteron toe van 9 naar 16 nmol/l, met een biochemische toename in 89% van de patiënten. Verhoogd niveau van totaal testosteron hield aan na acht jaar behandeling. Bij behandeling met CC ervoer 74% van de patiënten verbetering van de hypogonadale symptomen. Laag-normaal luteïniserend hormoon vóór CC-behandeling was voorspellend voor een betere testosteronrespons. Tijdens CC-therapie werden weinig, niet-ernstige bijwerkingen gemeld. Concluderend, CC is een effectieve therapie op korte en lange termijn, die zowel klinische symptomen als biochemische markers van mannelijk hypogonadisme verbetert met weinig bijwerkingen en goede veiligheidsaspecten.
Sentiment and structure in word co-occurrence networks on Twitter
Authors: Fudolig Mikaela Irene , Alshaabi Thayer , Arnold Michael V. , Danforth Christopher M. , Dodds Peter Sheridan 
Published: February 2022

AbstractWe explore the relationship between context and happiness scores in political tweets using word co-occurrence networks, where nodes in the network are the words, and the weight of an edge is the number of tweets in the corpus for which the two connected words co-occur. In particular, we consider tweets with hashtags #imwithher and #crookedhillary, both relating to Hillary Clinton’s presidential bid in 2016. We then analyze the network properties in conjunction with the word scores by comparing with null models to separate the effects of the network structure and the score distribution. Neutral words are found to be dominant and most words, regardless of polarity, tend to co-occur with neutral words. We do not observe any score homophily among positive and negative words. However, when we perform network backboning, community detection results in word groupings with meaningful narratives, and the happiness scores of the words in each group correspond to its respective theme. Thus, although we observe no clear relationship between happiness scores and co-occurrence at the node or edge level, a community-centric approach can isolate themes of competing sentiments in a corpus.
