In all countries, transport is considered as the basis for ensuring economic, social, military, environmental and other types of national security. It is provided more than 200 billion dollars in the US, about 200 billion dollars in Japan, more than 100 billion euros in Germany on the development of transport system. In Russia, for these purposes, is spent 14-15 times less. The purpose of environmental security's transportation ensuring - protection of life and health of people, the environment, cargo and vehicles, the sustainability of transport communications and transport infrastructure in normal conditions, in emergency situations and in wartime. Man, in the process of knowing the surrounding material world, forms “speculative” (ideal) ideas about how this world is arranged and how it functions. The basis of such knowledge is intuitive or conscious modeling. The initial level of visual modeling is the multipoint representation of the object of study, so: any phenomenon, object, process, object, definition, and other elements of the conceptual layer of consciousness are put in correspondence with the “point”. The further procedure of visual modeling involves the identification of all the points involved and the interrelations between them (the “logician”), this procedure will provide insight into infographic models of anthropotechnology management in the conditions of modern economic fundamentals and trends in the development of a market economy for the application of anthropotechnical management infographic models. Certification of manual labor's mechanization and transportation of construction cargo and structures (СMIT) - is one of the important construction service packages.

This paper reports a study that identified andcategorised the modifications to the 5thEdition of the British Standard Method ofMeasurement (SMM5) of building works inGhana. Typical modifications involved ‘costinsignificant items’, ‘minor labour items’,‘custom units of measurement’, ‘methodrelated items’, ‘combinable items’,‘subordinate items’, and ‘items of minorinformative impact’. It was also observed thatthe desirable characteristics/ qualities ofstandard methods of measurement (SMM) ofbuilding work were noteworthy, since theyprovide insight into the nature of a SMMrequired for the construction industry inGhana.The research reviewed available literature,various SMMs and bills of quantities (BQs).The relevance of the modifications andSMM characteristics identified wasconfirmed by a survey of the opinions ofprofessional quantity surveyors conductedthrough a carefully designed questionnaire.Inferences from the opinion survey formedthe basis for grouping both SMMmodifications found and the desired qualitiesof a SMM for Ghana.Survey respondents confirmed all theidentified modifications to the British SMM,except for the elimination of items of minorinformative impact. It was held that allinformation was relevant in measurement.Desirable characteristics of a SMM were ratedin decreasing order of relevance as: easylocation of items; cost significance; simplicity;thoroughness; ease of cost analysis; goodpractice; conciseness; adoptability; precision;industry practice; stakeholders’ opinion;custom classification; regional relevance; andinclusion of jargon. It was noted that therelevance of these characteristics may varyform one region to the other as a result oftechnological, cultural and legal differences.However, the desired SMM characteristicswere recommended as fundamental indeveloping an appropriate SMM for Ghana.

Fat deposition is important to carcass value and some palatability characteristics. Carcasses with higher USDA quality grades produce more value for producers and processors in the US system and are more likely to have greater eating satisfaction. Using genomics to identify genes impacting marbling deposition provides insight into muscle biochemistry that may lead to ways to better predict fat deposition, especially marbling and thus quality grade. Hereford steers (16) were managed the same from birth through harvest after 270 days on feed. Samples were obtained for tenderness and transcriptome profiling. As expected, steaks from Choice carcasses had a lower shear force value than steaks from Select carcasses; however, steaks from Standard carcasses were not different from steaks from Choice carcasses. A significant number of differentially expressed (DE) genes was observed in the longissimus lumborum between Choice and Standard carcass RNA pools (1257 genes, p < 0.05), but not many DE genes were observed between Choice and Select RNA pools. Exploratory analysis of global muscle tissue transcriptome from Standard and Choice carcasses provided insight into muscle biochemistry, specifically the upregulation of extracellular matrix development and focal adhesion pathways and the downregulation of RNA processing and metabolism in Choice versus Standard. Additional research is needed to explore the function and timing of gene expression changes.

This research explores the failure of competitively tendered projects in the UK construction industry to procure the most suited contractor(s) to conduct the works. Such work may have equal relevance for other developed nations globally. This research seeks to teach clients and their representatives that “lowest price” does not mean “best value”, by presenting a case study of a successfully negotiated tender undertaken by a small-to-medium enterprise (SME) contractor; SME studies are relatively scant in academic literature. By applying the “lessons learnt” principle, this study seeks to improve future practice through the development of a novel alternative procurement option (i.e., negotiation). A mixed philosophical stance combining interpretivism and pragmatism was used—interpretivism to critically review literature in order to form the basis of inductive research to discuss negotiation as a viable procurement route, and pragmatism to analyse perceptions of tendering and procurement. The methods used follow a three-stage waterfall process including: (1) literature review and pilot study; (2) quantitative analysis of case study data; and (3) qualitative data collection via a focus group. Our research underscores the need to advise clients and their representatives of the importance of understanding the scope of works allowed within a tender submission before discounting it based solely on price. In addition, we highlight the failings of competitive tendering, which results in increased costs and project duration once the works commence on site. These findings provide new contemporary insight into procurement and tendering in the construction industry, with emphasis on SME contractors, existing relationships, and open-book negotiation. This research illustrates the adverse effects of early cost estimates produced without first securing a true understanding of project buildability and programming. Our work concludes with a novel insight into an alternative procurement option that involves early SME contractor involvement in an open-book environment, without the need for a third-party cost control.

Abstract The rapid emergence of Coronavirus disease-2019 (COVID-19) caused by severe acute respiratory syndrome 2 coronavirus (SARS-CoV-2) as a pandemic that presents an urgent human health crisis. Many SARS-CoV-2 neutralizing antibodies (NAbs) were developed with efficient therapeutic potential. NAbs-based therapeutics against SARS-CoV-2 are being expedited to preclinical and clinical studies with two antibody drugs, LY3819253 (LY-CoV555) and REGN-COV2 (REGN10933 and REGN10987), approved by the US Food and Drug Administration for emergency use authorization for treating COVID-19. In this review, we provide a systemic overview of SARS-CoV-2 specific or cross-reactive NAbs and discuss their structures, functions and neutralization mechanisms. We provide insight into how these NAbs specific recognize the spike protein of SARS-CoV-2 or cross-react to other CoVs. We also summarize the challenges of NAbs therapeutics such as antibody-dependent enhancement and viral escape mutations. Such evidence is urgently needed to the development of antibody therapeutic interventions that are likely required to reduce the global burden of COVID-19.

Radio frequency identification (RFID) has been viewed as a promising technology for quite some time. Initially developed a couple of decades ago, the technology has been accompanied by predictions of imminent widespread adoption since its beginnings. A majority of retailers and other users are now using or planning to use the technology. This paper employs a combination of the technology-organization-environment (TOE) model and the 3-S (substitution, scale, structural) model to analyze the long journey of RFID adoption in retail. Top retail executives in the US and Europe were interviewed to investigate RFID adoption patterns based on differences in technological, organizational, and environmental circumstances. As the retail industry is moving into a post-adoption era, these results demonstrate the current stage of retail RFID adoption, identify factors playing important roles over time as motivators or impediments, and provide some insight into the slow pace of adoption.

AbstractAcquisition of genes through horizontal gene transfer (HGT) allows microbes to rapidly gain new capabilities and adapt to new or changing environments. Identifying widespread HGT regions within multispecies microbiomes can pinpoint the molecular mechanisms that play key roles in microbiome assembly. We sought to identify horizontally transferred genes within a model microbiome, the cheese rind. Comparing 31 newly-sequenced and 134 previously sequenced bacterial isolates from cheese rinds, we identified over 200 putative horizontally transferred genomic regions containing 4,733 protein coding genes. The largest of these regions are enriched for genes involved in siderophore acquisition, and are widely distributed in cheese rinds in both Europe and the US. These results suggest that horizontal gene transfer (HGT) is prevalent in cheese rind microbiomes, and the identification of genes that are frequently transferred in a particular environment may provide insight into the selective forces shaping microbial communities.

The researcher called for economic research to consider the potential effect of advancement in technology on analysis of economic data in Eddison Walters Modern Economic Analysis Theory in the future represented a paradigm shift in economic analysis that will significantly reduce the potential for error due to data distortion in the future. The foundation of the world&#39;s economy is based on the sharing of information, yet very little attention has been given to the effect of technology advancement in the analysis of data. The researcher of the current study highlighted the critical nature of sharing information to the development of the world&rsquo;s economy in the past, as well as the critical nature of sharing information to the world&rsquo;s economy today. Advancement in technology has drastically improved the sharing of information and has led to the globalized economy. The lack of evidence supporting the widely accepted theory of the Global Financial Crisis of 2007 and 2008 prompted the investigation by the current researcher aimed at gaining insight into economic factors that were responsible for conditions contributing to the Global Financial Crisis of 2007 and 2008. Walters (2018) presented evidence suggesting no financial bubble existed before the Global Financial Crisis of 2007 and 2008. The study resulted in the development of &ldquo;Eddison Walters Risk Expectation Theory of The Global Financial Crisis of 2007 and 2008&rdquo;. The theory presented an alternative explanation for the financial crisis. The researcher called for additional investigation to gain insight into the nature of the cause of the Global Financial Crisis of 2007 and 2008. Further investigation in Walters (2019) provided evidence supporting the idea, technological advancement led to the rapid growth in home prices before the Global Financial Crisis of 2007 and 2008. The result from the analysis of data in Walters (2019) revealed the following, 0.989 Adjusted R-square, 194.041 Mean Dependent Variable, 5.908 Square Error of Regression, and 488.726 Sum-of-Square Residual, from nonlinear regression analysis. The dependent variable in the study was, &ldquo;home purchase price&rdquo; and the independent variable was, &ldquo;advancement in technology&rdquo;. The current study continued the investigation into factors that were described in the literature which set the conditions leading to the Global Financial Crisis of 2007 and 2008. Gaining insight into the effect of technological advancement on the significant increase in consumer debt prior to the Global Financial Crisis will significantly contribute to the understanding of the economic environment before the Global Financial Crisis of 2007 and 2008. Insight into the effect of advancement in technology on the increase in consumer lending prior to the Global Financial Crisis of 2007 and 2008, will significantly contribute to the understanding of the Global Financial Crisis of 2007 and 2008.
