Making of Pressure Springs From Low Carbon Steel St 37 Material as an Alternative to Standard Pressure Springs in Mold Construction Through Solid Carburation Processes
Authors: Setiawan Heri 
Published: June 2023

Compression Spring is one of standard components type that are widely used in machinery construction, as well as in mold construction that serves to restore the position of the ejector mould into position. This study aims to find alternative materials for standard compression spring using specimen test of low carbon steel St 37 in the form of a compression spring is made by using coiling process followed to heat treatment processes such as pack carburizing, hardening, quenching and tempering. To ensure the quality process, the tests should be done in the laboratory such us the hardness test, the distribution of hardness, microstructure and deflection of the spring test. The pack carburizing is done at a temperature of 925ºC with a holding time of 2.5 hours, followed by a case hardening process at a temperature of 870ºC with a holding time of 12.5 minute and quenched on medium oil and tempered at a temperature of 350ºC. The results of this research show that the method used to generate the average value of 456.57 HV and have ? – martensite microstructure and also the compression spring deflection average value of 18.625 N/mm on 613.9 N. Those data approaches the compression spring standard value of hardness, microstructure and deflection. Based on the data analysis, low carbon steel St 37 can be used as alternative material for standard compression spring.
Issues, Problems and Challenges of Enhancing Social Functioning among Children with Cognitive Disabilities in Tanzania: A Theoretical Review
Authors: Rwegoshora Harold , Mnyanyi Cosmas , Mohamed Fauzia 
Published: June 2023

The paper attempts to provide a theoretical and empirical perspective related to the issues, problems and challenges of enhancing social functioning among children with cognitive disability in Tanzania. Specifically, the study reviews three theories, namely empowerment, inclusive and ecological with a view of finding the challenges associated with the enhancement of children with cognitive disability. The study is a literature review based on survey from books, scholarly articles and other relevant sources seeking explanations on the enhancement of social functioning among children with cognitive disability. The reviewed literature were summarized, analysed, and synthesized. The findings reveal that, the theories used in social work practice have diverse and different foci of analysis and intervention. This is largely because addressing a social problem there are many variables and uncertainties in social work practice. Because of that, there is no one single objective “reality” in social theory and practice. Secondly, whereas theories such as the ecological describes the influence of different subsystems in the changing individual behaviour, other behaviours such as discrimination and social exclusion among people with disabilities do not seem to change. The study further reveals that the assumptions of the inclusive theory of developing positive social relationships (e.g. friendships and acquisition of social skills) have not been successful because of existence negative attitudes among societal members which are influenced by false beliefs about people with cognitive disability. The study concludes that, whereas the theories help social workers to understand complex human behaviour and social environment which influence their clients’ lives and the nature of social problems, there are no theories which help in understanding African realities. The study observes that, negative social environment and attitudinal change have a negative impact in facilitating positive behavioural change in as far as enhancing social functioning among children with cognitive disability. The study recommends that more research be conducted to address the existing prohibiting factors. It is further recommended that concerted be made among different actors including policy interventions to raise awareness of local communities.

Published: June 2023

AbstractA promising strategy to cure HIV‐infected individuals is to use latency reversing agents (LRAs) to reactivate latent viruses, followed by host clearance of infected reservoir cells. However, reactivation of latent proviruses within infected cells is heterogeneous and often incomplete. This fact limits strategies to cure HIV which may require complete elimination of viable virus from all cellular reservoirs. For this reason, understanding the mechanism(s) of reactivation of HIV within cellular reservoirs is critical to achieve therapeutic success. Methodologies enabling temporal tracking of single cells as they reactivate followed by sorting and molecular analysis of those cells are urgently needed. To this end, microraft arrays were adapted to image T‐lymphocytes expressing mCherry under the control of the HIV long terminal repeat (LTR) promoter, in response to the application of LRAs (prostratin, iBET151, and SAHA). In response to prostratin, iBET151, and SAHA, 30.5%, 11.2%, and 12.1% percentage of cells, respectively. The arrays enabled large numbers of single cells (>25,000) to be imaged over time. mCherry fluorescence quantification identified cell subpopulations with differing reactivation kinetics. Significant heterogeneity was observed at the single‐cell level between different LRAs in terms of time to reactivation, rate of mCherry fluorescence increase upon reactivation, and peak fluorescence attained. In response to prostratin, subpopulations of T lymphocytes with slow and fast reactivation kinetics were identified. Single T‐lymphocytes that were either fast or slow reactivators were sorted, and single‐cell RNA‐sequencing was performed. Different genes associated with inflammation, immune activation, and cellular and viral transcription factors were found.

Effective actions in supersymmetric gauge theories: heat kernels for non-minimal operators
Authors: Grasso Darren T. , Kuzenko Sergei M. 
Published: June 2023

AbstractWe study the quantum dynamics of a system ofnAbelian$$ \mathcal{N} $$N= 1 vector multiplets coupled to$$ \frac{1}{2}n\left(n+1\right) $$12nn+1chiral multiplets which parametrise the Hermitian symmetric space Sp(2n, ℝ)/U(n). In the presence of supergravity, this model is super-Weyl invariant and possesses the maximal non-compact duality group Sp(2n, ℝ) at the classical level. These symmetries should be respected by the logarithmically divergent term (the “induced action”) of the effective action obtained by integrating out the vector multiplets. In computing the effective action, one has to deal with non-minimal operators for which the known heat kernel techniques are not directly applicable, even in flat (super)space. In this paper we develop a method to compute the induced action in Minkowski superspace. The induced action is derived in closed form and has a simple structure. It is a higher-derivative superconformal sigma model on Sp(2n, ℝ)/U(n). The obtained$$ \mathcal{N} $$N= 1 results are generalised to the case of$$ \mathcal{N} $$N= 2 local supersymmetry: a system ofnAbelian$$ \mathcal{N} $$N= 2 vector multiplets coupled to$$ \mathcal{N} $$N= 2 chiral multipletsXIparametrising Sp(2n, ℝ)/U(n). The induced action is shown to be proportional to$$ \int {\textrm{d}}^4x{\textrm{d}}^4\theta {\textrm{d}}^4\overline{\theta}E\mathfrak{K}\left(X,\overline{X}\right) $$∫d4xd4θd4θ¯EKXX¯, where$$ \mathfrak{K}\left(X,\overline{X}\right) $$KXX¯is the Kähler potential for Sp(2n, ℝ)/U(n). We also apply our method to compute DeWitt’sa2coefficients in some non-supersymmetric theories with non-minimal operators.
Renormalisation of SMEFT bosonic interactions up to dimension eight by LNV operators
Authors: Bakshi Supratim Das , Díaz-Carmona Álvaro 
Published: June 2023

Abstract
We present the renormalisation group running of the bosonic operators of the Standard Model effective field theory (SMEFT) by the Lepton Number Violating operators (LNVs) at 1-loop order up to $$ \mathcal{O} $$
O
(v4/Λ4), with v ∼ 246 GeV as the electroweak scale and Λ as the SMEFT cut-off. Using these relations with the positivity bounds on Wilson coefficients of ϕ4D4 class, we derive sign constraints on the Wilson coefficients of LNV operators, for models where ϕ4D4 operators do not appear at tree-level. We inspect these constraints for the LNV Wilson coefficients generated from matching the Type-I and III seesaw models to SMEFT up to dimension seven at tree-level. We also exhibit the unique bounds induced by the T-parameter on LNVs.

AbstractTo understand in detail the transcriptional and functional overlap of IFN-I- and IFN-II-activated responses, we used an integrative RNAseq-ChIPseq approach in Huh7.5 cells and characterized the genome-wide role of pSTAT1, pSTAT2, IRF9 and IRF1 in time-dependent ISG expression. For the first time, our results provide detailed insight in the timely steps of IFNα- and IFNγ-induced transcription, in which pSTAT1- and pSTAT2-containing ISGF3 and GAF-like complexes and IRF1 are recruited to individual or combined ISRE and GAS composite sites in a phosphorylation- and time-dependent manner. Interestingly, composite genes displayed a more heterogeneous expression pattern, as compared to GAS (early) and ISRE genes (late), with the time- and phosphorylation-dependent recruitment of GAF, ISGF3 and IRF1 after IFNα stimulation and GAF and IRF1 after IFNγ. Moreover, functional composite genes shared features of GAS and ISRE genes through transcription factor co-binding to closely located sites, and were able to sustain IFN responsiveness in STAT1-, STAT2-, IRF9-, IRF1- and IRF9/IRF1-mutant Huh7.5 cells compared to Wt cells. Thus, the ISRE + GAS composite site acted as a molecular switch, depending on the timely available components and transcription factor complexes. Consequently, STAT1, STAT2 and IRF9 were identified as functional composite genes that are part of a positive feedback loop controlling long-term IFNα and IFNγ responses. More important, in the absence of any one of the components, the positive feedback regulation of the ISGF3 and GAF components appeared to be preserved. Together, these findings provide further insight in the existence of a novel ISRE + GAS composite-dependent intracellular amplifier circuit prolonging ISG expression and controlling cellular responsiveness to different types of IFNs and subsequent antiviral activity. It also offers an explanation for the existing molecular and functional overlap between IFN-I- and IFN-II-activated ISG expression.

Melanin-based plumage coloration is associated with exposure in tawny owls under novel conditions
Authors: Perrault Charlotte , Morosinotto Chiara , Brommer Jon E. , Karell Patrik 
Published: June 2023

Abstract

Intraspecific color variation is often associated with camouflage or protection, but melanin-based color variation is also linked to behavioral and physiological aspects including boldness. In the melanin-based plumage color polymorphic tawny owl (Strix aluco), the grey morph is known to be more cryptic than the brown morph. Using 19 captive tawny owls (11 grey and 8 brown), we tested if these two color morphs that differ in camouflage tend to differently use exposed perches in a familiar environment (home aviary) and a novel environment (experimental aviary), as well as whether their response to predation risk and mobbing cues differs. The two color morphs did not differ in their exposure under known conditions (in their home aviary), but brown tawny owls were more likely to use exposed perches than grey tawny owls after release in a novel environment.

Significance statement
Melanin-based coloration can be associated with several behavioral traits. However, it is still unknown how predators with genetically-based color polymorphism vary in their efficiency of active background choice and risk-prone behavior while facing predation risk or mobbing harassment. Using captive tawny owls, we investigated predators’ behavior (attention towards the stimulus and use of space) while confronted to mobbing events and predation risk. We showed that tawny owls were using their space differently according to their color morph in a novel environment (experimental aviary) but not in a familiar environment (home aviary).
Bird traits and their nutrient impact on terrestrial invertebrate populations
Authors: van der Vegt W. , Bokhorst S. 
Published: June 2023

AbstractBirds are a large nutrient vector from marine to terrestrial environments where the increased nutrient input typically results in greater primary production and enhanced microbial activity. Associated invertebrate populations however, show large response variability to bird nutrient subsidies. To explain this variable invertebrate response, we performed a meta-analysis (50 articles ranging from polar to tropical regions) where we compared the effect of bird presence on invertebrate populations between: bird taxa, nesting site selection, bird diet and climate regions. In addition, we quantified how different invertebrate taxa and trophic guilds respond to the presence of birds. Invertebrate abundance was on average > 1000% higher by bird presence, but there was little evidence for any specific bird-taxa effects on invertebrate abundance responses. Birds with a mixed diet increased Coleoptera populations the most. Invertebrate responses to bird presence were largest in polar regions but variation remained high. Not all species within communities responded to bird presence, indicating that nutrient limitation is species-specific or ecosystems are affected in different ways by birds. Furthermore, sampling strategies were inconsistent and may impact effect-sizes. Despite the contrasting nature of the different studies, an overall positive invertebrate abundance response was found in the presence of birds, with larger responses observed in polar regions. Standardized sampling approaches would resolve much of the remaining variability. As natural experiments, bird nests and affected areas are a prime spot to study community assembly rules and address issues of anthropogenic disturbance and climate change.
The association between diet quality, plant-based diets, systemic inflammation, and mortality risk: findings from NHANES
Authors: Wang Yoko Brigitte , Page Amanda J. , Gill Tiffany K. , Melaku Yohannes Adama 
Published: June 2023

Abstract
Purpose
To our knowledge, no studies have examined the association of diet quality and plant-based diets (PBD) with inflammatory-related mortality in obesity. Therefore, this study aimed to determine the joint associations of Healthy Eating Index-2015 (HEI-2015), plant-based dietary index (PDI), healthy PDI (hPDI), unhealthy PDI (uPDI), pro-vegetarian dietary index (PVD), and systemic inflammation with all-cause, cardiovascular disease (CVD), and cancer mortality risks by obesity status.

Methods
Participants from NHANES were included in cross-sectional (N = 27,915, cycle 1999–2010, 2015–2018) and longitudinal analysis (N = 11,939, cycle 1999–2008). HEI-2015, PDI, hPDI, uPDI, and PVD were constructed based on the 24-h recall dietary interview. The grade of inflammation (low, moderate, and high) was determined based on C-reactive protein (CRP) values and multivariable ordinal logistic regression was used to determine the association. Cox proportional hazard models were used to determine the joint associations of diet and inflammation with mortality.

Results
In the fully adjusted model, HEI-2015 (ORT3vsT1 = 0.76, 95% CI 0.69–0.84; p-trend =  < 0.001), PDI (ORT3vsT1 = 0.83, 95% CI 0.75–0.91; p trend =  < 0.001), hPDI (ORT3vsT1 = 0.79, 95% CI 0.71–0.88; p trend =  < 0.001), and PVD (ORT3vsT1 = 0.85, 95% CI 0.75–0.97; p trend = 0.02) were associated with lower systemic inflammation. In contrast, uPDI was associated with higher systemic inflammation (ORT3vsT1 = 1.18, 95% CI 1.06–1.31; p-trend = 0.03). Severe inflammation was associated with a 25% increase in all-cause mortality (ORT3vsT1 = 1.25, 95% CI 1.03–1.53, p trend = 0.02). No association was found between PDI, hPDI, uPDI, and PVD with mortality. The joint association, between HEI-2015, levels of systemic inflammation, and all-cause, CVD and cancer mortality, was not significant. However, a greater reduction in mortality risk with an increase in HEI-2015 scores was observed in individuals with low and moderate inflammation, especially those with obesity.

Conclusion
Higher scores of HEI-2015 and increased intake of a healthy plant-based diet were associated with lower inflammation, while an unhealthy plant-based diet was associated with higher inflammation. A greater adherence to the 2015 dietary guidelines may reduce the risk of mortality associated with inflammation and may also benefit individuals with obesity who had low and moderate inflammation.
Über die Ausbildung und Form von flüssigen Wülsten an gekrümmten Festkörperkanten
Authors: Sommer Oliver , Wozniak Günter 
Published: June 2023

ZusammenfassungWenn ein flüssiger Film ein festes Substrat in der Umgebung einer Ecke oder Kante benetzt, bildet das Fluid eine ausgeprägte Randwulst, in der Praxis auch als „Fettkante“ bezeichnet, aus, deren Form von verschiedenen Parametern abhängt. Die Ursache dieses Phänomens ist die Oberflächenspannung, welche Druckdifferenzen in der benetzenden Flüssigkeit aufgrund der Oberflächenkrümmung durch die Kantengeometrie verursacht. Der Formationsprozess dieser Wulst und ihre finale Form werden durch das Zusammenspiel von Kapillarität, Viskosität und Trägheitskräften bestimmt. In technischen Anwendungen wie etwa dem Beschichten von festen Oberflächen stellen diese Fettkanten oftmals Beschichtungsdefekte dar. In der Praxis versuchen Hersteller daher in vielen Fällen, diesen Effekt zu unterdrücken oder zumindest zu minimieren, um ein homogeneres Beschichtungsergebnis zu erhalten. Wir untersuchen daher in dieser Arbeit das Entstehen und Verhalten dieser Fettkanten numerisch und experimentell. Unsere Ergebnisse zeigen den relativen Einfluss der dominierenden Parameter auf mit dem Ziel, das Ausmaß und die Form dieser flüssigen Wülste gezielt beeinflussen oder sogar unterdrücken zu können.
Adsorption Efficiency of Bentonite Clay and Parrotia persica During Acid Mine Drainage Treatment for the Removal of Turbid Material
Authors: Ntwampe I. O. 
Published: June 2023

AbstractWe conducted jar tests on the efficacy of using various mixtures of pulverized bentonite clay and Parrotia persica plant to treat AMD from a mine in Mogale City, South Africa without adding alkalinity. Two nearly identical sets of experiments were conducted using the same materials after they were rinsed using distilled and potable waters, respectively, to remove impurities, and then dried in an oven at 60 °C for 24 h, after which they were pulverized again. The pH, electrical conductivity, oxidation reduction potential, turbidity, and metal concentrations were measured before and after the experiments. The samples were treated in a jar test using standard procedures, i.e. rapid and slow mixing and settling for 1 h. The results showed that increasing the concentration of P. persica relative to the bentonite improved treatment effectiveness and that the highest turbidity removal (> 96.8%) was produced by rinsing the mixtures with potable water, drying them, and then pulverizing them again. Potentially toxic metals were removed by more than 93.7%. The morphological structure of the SEM micrographs indicate that the removal mechanism involves both physical and chemical phenomena and that the clay and P. persica are both important, particularly to the physical aspects.
