The importance of a realistic leakage evaluation to support public awareness and acceptance for carbon capture and storage
Authors: Busch Andreas 
Published: October 2022

Carbon Capture and Storage is not only highly recommended by the IPCC as a mechanism to significantly lower carbon emissions to the atmosphere, it is now also gaining traction in terms of large-scale implementation. Its importance is increasing in many parts of the world to directly decrease emissions from industrial sources, but also to lower the carbon footprint of blue hydrogen production.With most CCS projects being planned for offshore locations, public acceptance is less of a determining factor than it used to be 10-20 years ago, where discussions were rather for onshore locations. CO2 leakage has always been a risk highlighted in the public debate, while no or minimal leakage has been reported for current CCS projects worldwide. However, as scientific community, we need to realistically highlight the risk of leakage across sealing units for CO2 stored to inform various stakeholders like regulators, the public and of course also operating companies.Caprock leakage needs to be studied across various length and time scales, considering the undisturbed matrix as well as fracture networks and faults; we need to consider advective and diffusive flow and transport and incorporate mineral alterations, potentially leading to changes in hydraulic or mechanical properties.This talk will highlight the current state of research, advancements and future research required for a realistic evaluation of caprock leakage. It will be based on past research related to matrix transport as well as current research focusing on single and multiphase flow along faults and fractures.

Factors Affecting Construction Productivity for Steel Rebar Work in Hot Climate Country
Authors: Aldahash Mohammed , Alshamrani Othman Subhi 
Published: October 2022

Introduction:
Construction industry is increasingly emphasizing productivity due to its effect on key performance indicators such as schedule, budget, and quality of work. This study aims to identify and rank the factors affecting the productivity of steel rebar work in construction projects in a hot climate. Among the activities involved in structural reinforced concrete work, fabricating and placing reinforced steel on a construction site is considered the most labor-intensive, outdoor, and time-consuming.

Methods:
In this paper, an intensive qualitative literature review is conducted to identify the factors affecting the productivity of steel rebar work in concrete construction. Initially, forty factors were identified from the literature affecting the productivity of steel rebar work in Saudi Arabia. Final list of thirty-seven factors was used in the questionnaire survey. The identical nature and core content of these factors are clustered and grouped into five categories: technical, labor, management, external, and financial. As part of this study, fifty contractors working in the Saudi Arabian construction industry are recruited to participate and complete a structured pilot study questionnaire.

Results:
The results of the questionnaire are weighted using the pairwise comparison method and then ranked based on the Analytic Hierarchy Process technique. The analysis of the thirty-seven factors results in a top ten list of the leading factors that directly impact the productivity of steel rebar work in concrete construction projects in Saudi Arabia. These factors are (1) humidity, (2) delay of salary, (3) sandstorms, (4) payment delay by client, (5) labor's low wage, (6) lack of financial incentives, (7) labor work experience and skills, (8) completeness of drawings, (9) poor labor relations, and (10) labor absenteeism. The general trend in these studies is that the factors tend to vary from jurisdiction to jurisdiction, from one construction project to another, and are directly related to the zone or country of construction.

Conclusion:
These findings benefit stakeholders working in the concrete construction industry in Saudi Arabia, particularly project managers, project planners, cost estimators, and civil design and site engineers working on construction projects.

BackgroundPassive, case-based surveillance underestimates the true extent of active infections in the population due to undiagnosed and untested cases, the exclusion of probable cases diagnosed point-of-care rapid antigen tests, and the exclusive use of at-home rapid tests which are not reported as part of case-based surveillance. The extent in which COVID-19 surveillance may be underestimating the burden of infection is likely due to time-varying factors such as decreased test-seeking behaviors and increased access to and availability of at-home testing.ObjectiveThe objective of this study is to estimate the prevalence of SARS-CoV-2 based on different definitions of a case to ascertain the extent to which cases of SARS-CoV-2 may be underestimated by case-based surveillance.MethodsA survey on COVID-19 exposure, infection, and testing was administered to calculate point prevalence of SARS-CoV-2 among a diverse sample of cohort adults from February 8, 2022, to February 22, 2022. Three-point prevalence estimates were calculated among the cohort, as follows: (1) proportion positives based on polymerase chain reaction (PCR) and rapid antigen tests; (2) proportion positives based on testing exclusively with rapid at-home tests; and (3) proportion of probable undiagnosed cases. Test positivity and prevalence differences across booster status were also examined.ResultsAmong a cohort of 4328, there were a total of 644 (14.9%) cases. The point prevalence estimate based on PCR or rapid antigen tests was 5.5% (95% CI 4.8%-6.2%), 3.7% (95% CI 3.1%-4.2%) based on at-home rapid tests, and 5.7% (95% CI 5.0%-6.4%) based on the case definition of a probable case. The total point prevalence across all definitions was 14.9% (95% CI 13.8%-16.0%). The percent positivity among PCR or rapid tests was 50.2%. No statistically significant differences were observed in prevalence between participants with a COVID-19 booster compared to fully vaccinated and nonboosted participants except among exclusive at-home rapid testers.ConclusionsOur findings suggest a substantial number of cases were missed by case-based surveillance systems during the Omicron B.1.1.529 surge, when at-home testing was common. Point prevalence surveys may be a rapid tool to be used to understand SARS-CoV-2 prevalence and would be especially important during case surges to measure the scope and spread of active infections in the population.

BackgroundDigital surveillance tools and health informatics show promise in counteracting diseases but have limited uptake. A notable illustration of the limits of such tools is the general failure of digital contact tracing in the United States in response to COVID-19.ObjectiveWe investigated the associations between individual characteristics and the willingness to use app-based contact tracing in Detroit, a majority-minority city that experienced multiple waves of COVID-19 outbreaks and deaths since the start of the pandemic. The aim of this study was to examine variations among residents in the willingness to download a contact tracing app on their phones to provide public health officials with information about close COVID-19 contact during summer 2020.MethodsTo examine residents’ willingness to participate in digital contact tracing, we analyzed data from 2 waves of the Detroit Metro Area Communities Study, a population-based survey of Detroit, Michigan residents. The data captured 1873 responses from 991 Detroit residents collected in June and July 2020. We estimated a series of multilevel logit models to gain insights into differences in the willingness to participate in digital contact tracing across a variety of individual attributes, including race/ethnicity, degree of trust in the government, and level of education, as well as interactions among these variables.ResultsOur results reflected widespread reluctance to participate in digital contact tracing in response to COVID-19, as less than half (826/1873, 44.1%) of the respondents said they would be willing to participate in app-based contact tracing. Compared to White respondents, Black (odds ratio [OR] 0.45, 95% CI 0.23-0.86) and Latino (OR 0.32, 95% CI 0.11-0.99) respondents were significantly less willing to participate in digital contact tracing. Trust in the government was positively associated with the willingness to participate in digital contact tracing (OR 1.17, 95% CI 1.07-1.27), but this effect was the strongest for White residents (OR 2.14, 95% CI 1.55-2.93). We found similarly divergent patterns of the effects of education by race. While there were no significant differences among noncollege-educated residents, White college-educated residents showed greater willingness to use app-based contact tracing (OR 6.12, 95% CI 1.86-20.15) and Black college-educated residents showed less willingness (OR 0.46, 95% CI 0.26-0.81).ConclusionsTrust in the government and education contribute to Detroit residents’ wariness of digital contact tracing, reflecting concerns about surveillance that cut across race but likely arise from different sources. These findings point to the importance of a culturally informed understanding of health hesitancy for future efforts hoping to leverage digital contact tracing. Though contact tracing technologies have the potential to advance public health, unequal uptake may exacerbate disparate impacts of health crises.

Published: October 2022

In this article, a model is established for the planning of the weekly distribution of refreshments in a company that produces 6 types of beverages in 3 Production Centers, with the potential use of 3 Distribution Centers and supplying 22 Consumer Centers located in Bogota. Due to the impact of transportation costs on the company profits, it is necessary to determine the optimal planning of the allocation of sources to destinations in the nodal network of the system and its subsequent routing with two types of vehicles. Therefore, a two-phase model is proposed. In the first, the initial optimal assignments are established by comparing two techniques; one based on the Open Transshipment Problem (OTP) and the other on the Capacitated Transshipment Problem (CTP), which determine the trips to be made from production centers to consumer centers using distribution centers as intermediaries. This comparison allowed to analyze its efficiency to choose the model with the lowest cost and number of trips. In the second phase, routing was performed on routes that do not use the full capacity of the vehicles. The routes were established through the Travelling Salesman Problem (TSP). As a result, a comprehensive model was obtained to carry out the planning of the product distribution, obtaining in Phase II the use of the OTM model, which presented 14% less distance; 2.6% less time and 0.28% less than the total cost compared to the CTP model. In Phase II 5 routes were obtained, of which Distribution Center 2 covers 59% of customers.

Published: October 2022

In the 21st century, innovations are necessary because they allow us to withstand the rapidly changing and growing competition in a globalized world. Entrepreneurs who do not introduce innovations face stagnation and lagging behind competitors. Regardless of the size of the enterprise, the volume of production or the field of activity, innovation should be the hallmark of any modern enterprise. The innovation processes that take place at enterprises are determined by an extensive constellation of both internal and external conditions, which should be considered in the category of stimulators, as well as barriers to innovation. Enterprises can use various typical strategies to create and implement innovations. However, they must decide how to act innovatively, which strategy to choose and how to use it to ensure market success.The article discusses the basic concepts and definitions of innovative activity of the enterprise, considers various approaches to the formulation of the concepts of innovative activity and innovation system. The basic principles of the mechanism of management of innovative activity of the enterprise are defined. The stages of formation of the organizational and economic mechanism of innovation management were also investigated, the theoretical foundations of the formation of such a mechanism were worked out.

Published: October 2022

Production of Arumanis mango shows an increase, however to meet the needs of the export markets, quarantine regulations are hampered because mango is a host for fruit flies. The combination of hot water treatment (HWT) and waxing is an alternative for fruit fly disinfestation and maintaining quality. The purpose of this study was to determine the effect of HWT and waxing on the quality of Arumanis mango. Arumanis mangoes at 85% maturity were obtained from farmers in Cirebon having average weight of 400-450 g. The HWT was carried out at 47.0°C for 65 minutes and 75 minutes then waxing the fruit in: 1.5% chitosan (P1), 6% beeswax (P2) and a combination of beeswax 6% + chitosan 1.5% (P3). After the treatment, the fruit quality was analyzed every 4-day including hardness, weight loss, total soluble solids, color, respiration rate, total plate count, and organoleptic test. The best treatment was HWT at 47.0°C for 65 minutes and waxing using a combination of beeswax and chitosan. This combination treatment resulted in fruit quality with hardness was 1.72 kgf weight loss of 0.05%; total dissolved solids of 13.4°Brix; and color L* a* b*, of respectively 43.9 ;16.7; 28.2, the respiration rate of 5.2 ml O2/kg.h and CO2 production were of 7.1 ml CO2/kg.h and total plate count of 1.25 × 103 CFU/ml.

Published: October 2022

Abstract
This paper analyses the structural changes of the underlying stock and currency markets as well as the industrial productions by using a minimum spanning tree graph on a Central and East European sample. The aim is to point out the similarities and differences of the COVID-19 pandemic compared to previous recessions, namely the Dot-com crisis in the early 2000s and the Subprime crisis around 2008. Focusing on the incidence, closeness, and betweenness properties of the graph, we are looking for the emergence of a shock-propagating hub. We identify such a hub during the Subprime crisis but not during the COVID-19 pandemic, which points to the higher efficiency of the economic policy to absorb the worst effects of the crisis.
