Published: May 2020

Abstract
This study concerns the weldability of dissimilar Ultra high-strength steel (UHSS) and advanced high-strength steel (AHSS), which is used in the modern machine industry. The materials offered superior strength as well as relatively low weight, which reduces microstructure contamination during a live cycle. The choice of the welding process base of the base material (BM) and welding parameters is essential to improve the weld joint quality. S700MC/S960QC was welded using a gas metal arc welding (GMAW) process and overmatched filler wire, which was performed using three heat input (7, 10, and 15 kJ/cm). The weld samples were characterized by a Vickers-hardness test, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). The test reveals a decrease of softening areas in the HAZ and the formation of the stable formation of Bainite-Ferrite for S700MC and Bainite-martensite for S960QC when the heat input of 10 kJ/cm is used. It is recommended to use the GMAW process and Laser welding (Laser beam-MIG), with an optimal welding parameter, which will be achieved a high quality of manufacturing products.

Abstract
This paper provides a critical review on the current status of graphene-reinforced metal matrix composites (GRMMCs) in an effort to guide future work on this topic. Metal matrix composites are preferred over other types of composites for their ability to meet engineering and structural demands. Graphene is considered an ideal reinforcement material for composites due to its unique structure and extraordinary physical, thermal, and electrical properties. Incorporating graphene as a reinforcement in metals is a way of harnessing its extraordinary properties, resulting in an enhanced metallic behavior for a wide variety of applications. Combining graphene with bulk metal matrices is a recent endeavor that has proven to have merit. A systematic study is needed to critically examine the efforts applied in this field, the successes achieved, and the challenges faced. This review highlights the three main pillars of GRMMCs: synthesis, structure, and properties. First, it discusses the synthesis techniques utilized for the fabrication of GRMMCs. Then, it highlights the resulting microstructures of the composites, including graphene dispersion and interfacial interactions. Finally, it summarizes the enhancements in the mechanical, electrical, thermal, and tribological properties of GRMMCs, while highlighting the effects of graphene type and content on those enhancements.

Authors: Buchanan Jenna K. , Plieger Paul G. 
Published: May 2020

Abstract

9Be solution NMR spectroscopy is a useful tool for the characterisation of beryllium complexes. An updated comprehensive table of the 9Be NMR chemical shifts of beryllium complexes in solution is presented. The recent additions span a greater range of chemical shifts than those previously reported, and more overlap is observed between the chemical shift regions of four-coordinate complexes and those with lower coordination numbers. Four-coordinate beryllium species have smaller ω
1/2 values than the two- and three-coordinate species due to their higher order symmetry. In contrast to previous studies, no clear relationship is observed between chemical shift and the size and number of chelate rings.

Authors: Musfirah Musfirah , Rangkuti Ahmad Faizal 
Published: May 2020

The environmental conditions of Code River were strongly influenced by anthropogenic activities that include industry, hospitals, domestic, and agriculture. The contamination status on the Code River according to BLH Yogyakarta reported in 2014 was heavily polluted based on STORET (≤-31). The riverside community were misusing the river for final disposal site, potentially contaminating it with lead (Pb). Local communities were potentially exposed to Pb toxicity through well water consumption. An Environmental Health Risk Assessment (EHRA) study of ingestion exposure of heavy metals was never conducted in the Code Riverside, making it interesting for further studies. The study aimed to determine human health risks of consumption of well water containing Pb in Code Riverside, Yogyakarta City using an observational design with an Environmental Health Risk Assessment approach. There were 9 environmental samples and 47 respondents selected based on certain criteria. Data was collected through environmental inspection and human health assessment, interviews and anthropometric data measurement of respondents. Data was analyzed by univariate (frequency distribution) and EHRA methods. The result showed that the noncarcinogenic risk level of Pb due to well water consumption from majority of research sites have RQ value (Risk Quotient) > 1, which means high potential risk to human health.

Published: May 2020

The textile industries’ growth in 2018 have contributed to national economic growth (Kemenperin, 2018). Enhancing competitiveness through conductive business climate is a strategic step to increase productivity (Kemenperin, 2017). Surakarta is one of the major cities in Indonesia famous for its textile products. Based on Indonesian Statistic Center, in 2016, the national textile industry productivity declined to 7.65%, directly affecting the productivity of textile industries in Surakarta, including PT IT. The weaving department of PT IT experienced the highest decline in work productivity with physical factor exposure more than Threshold Limit Value (TLV), including lighting intensity. This research aimed to analyze the correlation between the light intensity and worker productivity in 2018. This was a quantitative observational analytic research with cross sectional design in PT IT. From 50 workers in the weaving department, 32 were selected as samples through random sampling method. Light intensity was measured using Lux Meter ANA 999 in 32 measurement points. Work productivity was calculated using Productivity formula= Output (O)/ Input (I). Spearman correlation and SPSS program were used for data analysis. The result showed that there was a significant correlation between light intensity and worker’s productivity (p=0.000, r=0.629).

Published: May 2020

Adolescent fertility is an important health and social problem because it is related to the level of morbidity and mortality of mothers and children. The results of the 2017 IDHS show that 7% of women aged 15-19 are already mothers, 5% have given birth, and 2% are pregnant with their first child. The data shows that adolescents are already sexually active, but still have an understanding of low reproductive health. The purpose of this study was to determine the effectiveness of community-based health communication models that developed to improve access to information and public knowledge related to contraceptive methods in young married couples in Rembang Regency in 2019. This research used Research and Development design with a quasi-experimental data collection method. The population in this study were adolescents who married at a young age in Rembang District, while the sample was adolescents who married young in Sedan and Kragan villages (intervention group), Menoro and Ngasinan (control group). Quantitative data analysis uses univariate, bivariate, and multivariate, while for qualitative data use grounded theory. The effectiveness test showed significant data for knowledge (p = 0,000), attitudes (p = 0.003), access to information (0.012), preferences (p = 0.001), and access to contraception (p = 0,000). It can be concluded that the community-based health communication model can improve knowledge, attitudes, access to information, preferences, and access related to contraception in early married couples

Abstract
A long-standing effort in biology is to precisely define and group phenotypes that characterize a biological process, and the genes that underpin them. In Saccharomyces cerevisiae and other organisms, functional screens have generated rich lists of phenotypes associated with individual genes. However, it is often challenging to identify sets of phenotypes and genes that are most closely associated with a given biological process. Here, we focused on the 166 phenotypes arising from loss-of-function and the 86 phenotypes from gain-of-function mutations in 571 genes currently assigned to cell cycle-related ontologies in S. cerevisiae. To reduce this complexity, we applied unbiased, computational approaches of correspondence analysis to identify a minimum set of phenotypic variables that accounts for as much of the variability in the data as possible. Loss-of-function phenotypes can be reduced to 20 dimensions, while gain-of-function ones to 14 dimensions. We also pinpoint the contributions of phenotypes and genes in each set. The approach we describe not only simplifies the categorization of phenotypes associated with cell cycle progression but might also potentially serve as a discovery tool for gene function.
Effects of Energy Consumption on GDP: New Evidence of 24 Countries on Their Natural Resources and Production of Electricity
Authors: Khan Rabnawaz , Kong YuSheng 
Published: May 2020

Because of rapid economic expansion, China, the USA, and India have become the largest energy producers and sources of CO2 emissions in the world. They burned over 45% of global fuels in 2016. Meanwhile, the developing strategies of 24 polluted states to decrease fossil energy consumption without additional economic output. This paper explores the effect of world top polluted countries’ CO2 emission, their GDP and production of electricity by potential indicators and identifies the basic factors that contribute to changes in an environment where petroleum, natural gas, coal, nuclear, biomass, and other renewable energy and hydroelectric sources are examined with GDP per capita. We estimate our data for the period from 1968 to 2017 and use the GLM model. The results show that more production of electricity is causing abnormal CO2 emissions. The Granger causality test shows that there is a unidirectional relationship between energy consumption and economic advancement. Also, there is a short-run bidirectional causality that exists among the energy indicators. We find a unilateral causality between energy consumption and economic growth. Therefore, the consumption of energy might be conductive of 24 (polluted) countries and better economic development; the consumption of energy may be failsafe and guaranteed, while we should limit the resources of countries.

Late Into The Night, I Sit Alone in My Study, Listening. in This, I Am Not Unlike The Title Character of Italo Calvino's “A King Listens,” one of three stories that make up hisUnder a Jaguar Sun, first published as a collection in 1986. The aim of Calvino's king is the acoustic surveillance of his realm, every corner of which is connected to the throne room by a twisting network of resonant tubes. Day in, day out, he listens, learning much, but feeling very little.This royal listener would later capture the imagination of the philosopher Adriana Cavarero, who opens her bookFor More than One Voicewith a close reading of the story. For Cavarero, Calvino's king is very much like philosophy in its traditional Western form, listening for bodiless, universallogos, the Greek word for “word” that ancient philosophy uses to designate the rational order of the cosmos. In the story, the king is brought to his knees, suddenly and unexpectedly, by the sound of a woman singing. For Cavarero, this single, singular voice embodies the particularity that philosophy traditionally excludes in the name of the universal.
Aural Philology and the Latin Recordings of the Harvard Vocarium
Authors: Howley Joseph A. 
Published: May 2020

Philology is Often Taken to Be a Matter of Eyes and Hands: We Make Sense of Written Text, And Then Write Down Our Findings. This essay is interested in philology as a matter of the ear. Since Walter Ong declared the fundamental opposition of orality and literacy, humanists have located the lost, spoken origins of written text in the realm of orality. By contrast, aurality, the way texts are encountered by the ear, is a condition of consumption, which is to say reading, and so by considering aurality we are also considering the history of reading.Sound recordings, created by phonographic technology, provide a useful critical framework for the history of reading. In addition to what we think of as the legible or intentional content of a recording, sound recordings have what audio engineers call “room tone”—the sonic signature of the space in which the recording was made, the equipment used to make it, and the specific placement of that equipment in relation to a subject. Although we learn to unhear room tone by means of what Jonathan Sterne calls “audile techniques” (137), its presence is always felt. By attuning our ears to the room tone of historical phonography, then, we can practice attuning our historians' ears to the barely perceptible silences, markers of space, and context in textual artifacts of historical reading culture.
Elsie McLuhan's Vocal Science
Authors: McDowell Paula 
Published: May 2020

Full out the plug in order to get back to the physical body.—Marshall McLuhan, 19 December 1978Four Years Before a Massive Stroke Took Away his Ability to Speak, Marshall McLuhan Advised his Son Eric To “Develop the power and habit of listening. It is not a power that I have, and nobody ever told me how to go about getting it.” A notorious talker who would “lecture and discourse nonstop if anyone else was present” (Marchand 273), and who frequently telephoned his friends and colleagues in the wee hours of the morning to discuss his latest idea, this English professor turned media theorist was also one of the first academics to recognize and seize the opportunities offered by the new media of popular culture to reach audiences wider than the readerships of scholarly journals. From the 1960s onward, McLuhan made dozens of appearances on radio and television and even made a cameo film appearance: in Woody Allen'sAnnie Hall, he silences an arrogant Columbia University professor by declaring, “You know nothing of my work.” At once a raconteur and an aphorist, he was most alive when processing his thoughts aloud to a live audience, whether in a Canadian Broadcasting Corporation recording studio, at his family dinner table, or in his office at the University of Toronto, where he dictated many of his later writings (books, articles, and correspondence) to his secretary, Margaret Stewart (“Marge”). “Telephone conversations with Marshall would turn into miniature symposia,” recalled the University of Toronto president Claude Bissell (qtd. in Nevitt 284). Ironically, given his own wee-hours use of the telephone, McLuhan theorized this medium of secondary (or electronic) orality as “an intensely personal form that ignores all the claims of visual privacy prized by literate man” and as “an irresistible intruder in time or place” (Understanding Media296).

Published: May 2020

Significance StatementAlthough antibiotics have been associated with an increased risk of kidney stones, particularly early in life, perturbations of the gut microbiome and metabolome in early-onset nephrolithiasis have not been investigated. Using shotgun metagenomic sequencing and untargeted metabolomics of stool samples in a study of 44 children with kidney stones and 44 controls matched for age, sex, and race, the authors found that 31 bacterial taxa—including seven butyrate-producing taxa and three that degrade oxalate—were less abundant among children with calcium oxalate stones. Levels of 18 metabolites differed between cases and controls and correlated with the fecal bacteria that were less abundant among children with nephrolithiasis. Such disruptions in the gut microbiome and metabolome may thus be determinants of early-onset disease and may explain the association between antibiotics and nephrolithiasis.BackgroundThe relationship between the composition and function of gut microbial communities and early-onset calcium oxalate kidney stone disease is unknown.MethodsWe conducted a case-control study of 88 individuals aged 4–18 years, which included 44 individuals with kidney stones containing ≥50% calcium oxalate and 44 controls matched for age, sex, and race. Shotgun metagenomic sequencing and untargeted metabolomics were performed on stool samples.ResultsParticipants who were kidney stone formers had a significantly less diverse gut microbiome compared with controls. Among bacterial taxa with a prevalence >0.1%, 31 taxa were less abundant among individuals with nephrolithiasis. These included seven taxa that produce butyrate and three taxa that degrade oxalate. The lower abundance of these bacteria was reflected in decreased abundance of the gene encoding butyryl-coA dehydrogenase (P=0.02). The relative abundance of these bacteria was correlated with the levels of 18 fecal metabolites, and levels of these metabolites differed in individuals with kidney stones compared with controls. The oxalate-degrading bacterial taxa identified as decreased in those who were kidney stone formers were components of a larger abundance correlation network that includedEggerthella lentaand severalLactobacillusspecies. The microbial (α) diversity was associated with age of stone onset, first decreasing and then increasing with age. For the individuals who were stone formers, we found the lowestαdiversity among individuals who first formed stones at age 9–14 years, whereas controls displayed no age-related differences in diversity.ConclusionsLoss of gut bacteria, particularly loss of those that produce butyrate and degrade oxalate, associates with perturbations of the metabolome that may be upstream determinants of early-onset calcium oxalate kidney stone disease.

Objective To study the prognostic role of current serum biomarkers in patients with myocardial infarction (MI) by constructing a multifactorial model for prediction of cardiovascular complications (CVC) in remote MI. Acute coronary syndrome is a major cause of death and disability in the Russian Federation. Introduction of current biomarkers, such as N-terminal pro-brain natriuretic peptide, stimulating growth factor (ST2), and centraxin-2 (Pentraxin, Ptx-3), provides more possibilities for diagnostics and calculation of risk for CVC.Materials and Methods Concentrations of biomarkers were measured in 180 patients with MI (mean age, 61.4±1.7) upon admission. At one year, specific and composite endpoints were determined (MI, acute cerebrovascular disease, admission for CVD, and cardiovascular death). Based on this information, a prognostic model for subsequent events was developed.Results A mathematical model was created for computing the development of a composite endpoint. In this model, the biomarkers NT-proBNP, Ptx-3 and, to a lesser extent, ST2 demonstrated their prognostic significance in diagnosis of CVC with a sensitivity of 78.79 % and specificity of 86.67 % (area under the curve, AUC 0.73).Conclusion In patients with remote MI, the biomarkers NT-proBNP, ST2, and Ptx-3 improve prediction of CVC.
