Time-Dependent Behavior of Concrete-Filled Steel Tubular Arch Bridge

This paper develops a simplified method using a summation procedure and a related computer program to calculate the time-dependent behavior of a concrete filled steel tubular CFST arch bridge based on the geometric compatibility principle, a step-by- step time incremental process, and self-equilibrium equations. An experimental test on a scaled 1:5 segmental model of the main arch ribs of the Maocaojie Bridge was used to confirm the effectiveness of the proposed calculation method for evaluating the long-term behavior of CFST arch bridge under sustained load. It is concluded that: 1 the numerical results were in good agreement with the experimental results, demonstrating that the proposed analytical model is capable of predicting long-term effects for CFST arch bridges; 2 the stresses in the steel tubes increased, and the compressive stresses in the concrete decreased due to the effects of concrete creep and shrinkage. The maximum relaxation of the compressive stress in concrete due to concrete creep was 52.7% of the initial concrete stress, and the maximum increase of stress in the steel tubes was 27.3%; and 3 more than 90% of the total creep of the concrete took place in the first year. Subsequent creep of the concrete was limited because of the lack of water exchange between the structure and atmosphere and the reduction of compressive stress in the concrete.
A three-phase inverter with a neutral leg with space vector modulation

A three-phase inverter with a neutral leg is presented in this paper, in comparison with a conventional neutral point clamped three-phase inverter with split DC link capacitors, to deal with load unbalance in a high-power rotary standalone power supply system. With the additional neutral leg, the space vector modulation control is much more complex, and there is no precedent literature addressing this issue. In this paper a general definition of space vector in a three-dimensional space is described. Space vector modulation control of this inverter is discussed, as well as design considerations.
Addressing Sustainability within Public Procurement of Food: A Systematic Literature Review

Public procurement has been recognized as a tool to promote more sustainable production and consumption practices. As such, an increasing body of literature has become available in recent years focusing on the sustainable public procurement of food. This article reviews the literature on the sustainable public procurement of food with the aim to analyze how sustainability is framed. This is done by analyzing what aspects of sustainability are emphasized and what practices are identified as sustainable. A systematic literature review was conducted between the years 2000 and 2020, identifying 103 articles. Results from the literature review indicate that the focus has primarily been on studies to evaluate and explore policy and good practices for procuring sustainable foods. A dominant focus on specific foods types and origins, e.g., those locally sourced and organic foods, is highlighted by a large share of the literature to address all three sustainability pillars. We observed that most articles focus on all three pillars of sustainability (environmental, social, and economic), addressing different aspects and types of foods, although the focus varied depending upon geographic location. Despite many studies identifying opportunities and potential, few articles assess the sustainability or outcomes of procurement processes through quantitative or qualitative methods or how actors in the procurement process can improve procurement toward more sustainable foods. This indicates a need for further case studies and guidelines to measure the development, progress, and performance of public food procurement.
Usability, User Acceptance, and Health Outcomes of Arm-Support Exoskeleton Use in Automotive Assembly

In an 18-month study of arm-support exoskeleton (ASE) use in automotive manufacturing, usability responses were consistent over time and ASEs appeared effective in reducing physical demands. Perceived performance, and fit and comfort, were key determinants for ASE intention-to-use. ASE use also may decrease the likelihood of a work-related medical visit. Objective: Examine arm-support exoskeleton (ASE) user experience over time, identify factors contributing to ASE intention-to-use, and explore whether ASE use may influence the number of medical visits. Methods: An 18-month, longitudinal study with ASE (n = 65) and control groups (n = 133) completed at nine automotive manufacturing facilities. Results: Responses to six usability questions were rather consistent over time. ASE use perceived effective in reducing physical demands on the shoulders, neck, and back. Perceived job performance, and overall fit and comfort, appeared to be key determinants for ASE intention-to-use. Based on medical visits among both groups, ASE use may decrease the likelihood of such visits. Conclusions: These field results support the potential of ASEs as a beneficial ergonomic intervention, but also highlight needs for further research on ASE designs, factors driving intention-to-use, and health outcomes.
Before and After Ban the Box: Who Complies with Anti-Discrimination Law?

Ban the Box (BTB) laws are an anti-discrimination policy intended to promote employment for persons with criminal records. However, research on law and organizations shows that firms often fail to comply with legal directives or engage in symbolic compliance that fails to alter day-to-day business practices. We consider whether BTB contributed to attitudinal or behavioral shifts among hiring managers and changes in job applications. We analyze a unique set of in-depth interviews (N = 30) and entry-level job applications (N = 305) collected from the same workplaces in 2008 and 2016, assessing the impact of state BTB legislation. We find: (1) that one in five organizations were noncompliant, with noncompliance twice as likely among employers who discriminated against applicants with criminal records pre-BTB and that widespread lack of knowledge and lack of enforcement of BTB appears to affect noncompliance; (2) organizations maintained considerable continuity in hiring practices and attitudes between 2008 and 2016, regardless of personnel changes and statewide implementation of BTB; and (3) post-BTB, strong warnings about criminal background checks at later stages of the hiring process emerged as an alternative source of gatekeeping. These findings contribute to the law and organizations literature by highlighting the importance of enforcement and limits of law for combating discrimination.
Limits of Land Capitalization and Its Economic Effects: Evidence from China

Academic debates over the advantages and disadvantages of land capitalization are ongoing in China, but the fundamental issues behind the debate have not been adequately explored. We suggest that the core issue in land capitalization is the degree of capitalization. This study first theoretically deduced the existence of land capitalization limits; then, we used panel data from 35 key cities to conduct an empirical test, and finally we analyzed the current risk of excessive land capitalization in China. The results indicated that the mutual restriction of multiple land attributes determined the limits of land capitalization. Therefore, land capitalization has been categorized into two types—moderate and excessive—which produce different economic effects. The degree of land capitalization and real economic growth showed a significant inverted-U relationship, and the turning point appeared when the land capital value reached 2.5 times the land factor value. According to this threshold, we can infer that many key cities have been overcapitalized, which may lead to an economic recession and affect the growth prospects of China’s economy. Further analysis indicated that excessive land capitalization could be related to the unique Chinese style of decentralization. These conclusions have important policy implications for the reform of land marketization in countries undergoing economic transition. The goal of land reform is to allow the market mechanism to play a major role in land resource allocation, but the excessive capitalization of land must be prevented.
The effect of management and social interaction on the intra-firm diffusion of electronic mail systems

Can management affect the rate by which organizational members adopt a new computer based communication medium? The question is addressed by comparing the rate by which employees start to use an electronic mail system (EMS) and case descriptions across four departments during a five year period in a large Swedish manufacturing company. Data on EMS use are fitted to a model describing the spread of use as a function of social and management influence. Data are consistent with the hypothesis that the rate of new users of EMS can be influenced by both department-level management and peers. Faster growth in use occurred when department-level management exercised implementation efforts. The rate of growth increased significantly when a local information center (IC) was established. The more resources the local IC was supplied with the higher the rate of growth in EMS use. Management of the implementation process may be especially preferred when introducing end-use network technologies in organizations due to interdependent demand among users.
Central Nervous System Profiling of Hericium erinaceus Biomass Powder by an Electropharmacogram Using Spectral Field Power in Conscious Freely Moving Rats

Changes of field potentials recorded from implanted electrodes into the depth of the brain of rats served to analyse the action of plant-derived extracts in comparison to food supplements and reference drugs. Frequency analysis of the data and feeding of the results into discriminant analysis allowed indication dependent classification of the effects. The present investigation aimed at the neuro-physiological characterization of the effect of a preparation of Hericium erinaceus in this model.
Peroxisomes in intracellular cholesterol transport: from basic physiology to brain pathology

Peroxisomes are actively involved in the metabolism of various lipids including fatty acids, ether phospholipids, bile acids as well as the processing of reactive oxygen and nitrogen species. Recent studies show that peroxisomes can regulate cholesterol homeostasis by mediating cholesterol transport from the lysosomes to the endoplasmic reticulum and towards primary cilium as well. Disruptions of peroxisome biogenesis or functions lead to peroxisomal disorders that usually involve neurological deficits. Peroxisomal dysfunction is also linked to several neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease. In many peroxisomal disorders and neurodegenerative diseases, aberrant cholesterol accumulation is frequently encountered yet largely neglected. This review discusses the current understanding of the mechanisms by which peroxisomes facilitate cholesterol trafficking within the cell and the pathological conditions related to impaired cholesterol transport by peroxisomes, with the hope to inspire future development of the treatments for peroxisomal disorders and neurodegenerative diseases.
Climate Finance: Mapping Air Pollution and Finance Market in Time Series

Climate finance is growing popular in addressing challenges of climate change because it controls the funding and resources to emission entities and promotes green manufacturing. In this study, we determined that PM2.5, PM10, SO2, NO2, CO, and O3 are the target pollutant in the atmosphere and we use a deep neural network to enhance the regression analysis in order to investigate the relationship between air pollution and stock prices of the targeted manufacturer. We also conduct time series analysis based on air pollution and heavy industry manufacturing in China, as the country is facing serious air pollution problems. Our study uses Convolutional-Long Short Term Memory in 2 Dimension (ConvLSTM2D) to extract the features from air pollution and enhance the time series regression in the financial market. The main contribution in our paper is discovering a feature term that impacts the stock price in the financial market, particularly for the companies that are highly impacted by the local environment. We offer a higher accurate model than the traditional time series in the stock price prediction by considering the environmental factor. The experimental results suggest that there is a negative linear relationship between air pollution and the stock market, which demonstrates that air pollution has a negative effect on the financial market. It promotes the manufacturer’s improving their emission recycling and encourages them to invest in green manufacture—otherwise, the drop in stock price will impact the company funding process.
Effects of Manganese Hydroxychloride on Growth Performance, Antioxidant Capacity, Tibia Parameters and Manganese Deposition of Broilers

Simple Summary Manganese is a vital trace element for the growth of broilers. In order to meet the requirement of manganese in broiler production, the additives of manganese sources are usually added into the diet for broilers. Manganese hydroxychloride is a category of hydroxy trace minerals. The present study investigated the effect of dietary supplemental manganese as manganese hydroxychloride for growth performance, antioxidant capacity, tibial quality, and manganese deposition of broilers and recommended that optimal supplementation with manganese as manganese hydroxychloride in diets for broilers was 50–90 mg/kg. This study provides a rational recommendation for the application of manganese hydroxychloride in broiler diets. Abstract This study was conducted to investigate the effects of dietary supplementation with manganese hydroxychloride (MHC) on production performance, antioxidant capacity, tibial quality, and manganese (Mn) deposition of broilers. A total of 756 one-day-old male Arbor Acres broilers were randomly allotted to 7 treatments of 6 replicates with 18 broilers per replicate. Broilers were fed corn-soybean meal basal diets supplemented of 100 mg/kg Mn as Mn sulfate (MnSO4), or 0, 20, 40, 60, 80, 100 mg/kg Mn as MHC for 42 days. The growth performance of broilers was not affected by dietary MnSO4 or MHC (p > 0.05), whereas the dressing percentage increased linearly (p < 0.05) with increasing of dietary MHC addition level. The activities of catalase (CAT) and manganese superoxide dismutase (MnSOD), and total antioxidant capability (T-AOC) in serum and liver on day 42 increased linearly (p < 0.05) with increasing of dietary MHC level, while malondialdehyde (MDA) concentration reduced linearly (p < 0.05). The length, strength, and density index of tibia increased linearly (p < 0.05) on day 21 as MHC supplementation level increased; there were no differences between MnSO4 group and 40–100 mg/kg Mn as MHC groups in tibial parameters of broilers (p > 0.05). As supplemental MHC levels increased, the Mn contents in heart, liver, kidney, and tibia increased linearly on day 42 (p < 0.05). In summary, dietary supplementation with MHC improved antioxidant capacity, bone quality, and Mn contents in broilers, but no effects on growth performance were detected. Based on the results of this study, dietary inclusion of 50–90 mg/kg Mn in the form of MHC to broilers is recommended.
Mutation analysis and characterisation of F9 gene in haemophilia-B population of India

Background Hemophilia B (HB) is an X-linked bleeding disorder resulting from coagulation factor IX defects. Over 3,000 pathogenic, HB-associated mutations in the F9 gene have been identified. We aimed to investigate the role of F9 variants in 150 HB patients using sequencing technology. Methods F9 gene sequences were amplified from peripheral blood-derived DNA and sequenced on an Applied Biosystems (ABI) 3500 Sanger sequencing platform. Functional and structural predictions of mutant FIX were analyzed. Results Among 150 HB patients, 102 (68%), 30 (20%), and 18 (12%) suffered from severe, moderate, and mild HB, respectively. Genetic analysis identified 16 mutations, including 3 novel mutations. Nine mutations (7 missense and 2 stop-gain) were found to be pathogenic. Only 3 mutations (c.127C>T, c.470G>A, and c.1070G>A) were associated with different severities. While 2 mutations were associated with mild HB cases (c.304C>T and c.580A>G), 2 (c.195G>A and c.1385A>G) and 3 mutations (c.223C>T, c.1187G>A, and c.1232G>A) resulted in moderate and severe disease, respectively. Additionally, 1 mutation each was associated with mild-moderate (c.*1110A>G) and mild-severe HB disease (c.197A>T), 4 mutations were associated with moderate-severe HB cases (c.314A>G, c.198A>T, c.676C>T, and c.1094C>A). FIX concentrations were lower in the mutated group (5.5±2.5% vs. 8.0±2.5%). Novel p.E66D and p.S365 mutations were predicted to be pathogenic based on changes in FIX structure and function. Conclusion Novel single nucleotide polymorphisms (SNPs) largely contributed to the pathogenesis of HB. Our study strongly suggests that population-based genetic screening will be particularly helpful to identify risk prediction and carrier detection tools for Indian HB patients.
An Attempt to Find an Empirical Model between Barkhausen Noise and Stress

A nonlinear empirical model between stress and Barkhausen noise is identified in this study. The identification procedure uses a genetic algorithm followed by a Nelder-Mead optimization procedure. The model is identified with the data set where an external load is applied to RAEX400 low alloyed hot-rolled steel samples. The results of the study show that the identified model performs well in stress predictions. The identified model includes three terms which are in accordance with the literature.
Effects of Signage and Floor Plan Configuration on Wayfinding Accuracy

Signage is commonly employed to enhance wayfinding efficiency, especially in buildings with complex floor plan configurations. This study examines the influence of floor plan complexity and several types of signage on wayfinding within a series of buildings on a university campus. The study used a 5 x 3 factorial experimental design. The first factor, complexity of floor plan configuration, is defined through five alternatives. The second factor, signage, has three conditions: no signage, textual signage, or graphic signage. The results show that as floor plan complexity increases, wayfinding performance decreases. Graphic signage produced the greatest rate of travel in all settings, but textual signage was the most effective in reducing wayfinding errors, such as wrong turns and backtracking. Overall, the addition of signage resulted in a 13% increase in rate of travel, a 50% decrease in wrong turns, and a 62% decrease in backtracking across the five settings. However, plan configuration was found to exert a significant influence regardless of signage, because the wayfinding performance of participants with access to signage in the most complex settings remained equivalent to, or significantly poorer than, those in the simplest settings with no signage.
Tunneling into interface states as reliability monitor for ultrathin oxides

This paper reports experimental data and simulations of low-voltage tunneling in ultrathin oxide MOS devices. When the substrate is very heavily doped, a thermionic barrier is present that opposes the direct tunneling of gate electrons when the applied gate voltage is between 0 V and the flatband voltage. In such conditions, we show that the measured gate current cannot be explained by direct tunneling, but features an additional, dominant component. The temperature dependence of this extra component indicates that it is due to gate electrons tunneling into the anode interface states. By comparing measurements and simulations, it is possible to exploit this extra current to estimate the interface state density within the silicon band gap. In addition, it is shown that this tunneling current component is very sensitive to electrical stress and allows a clear detection of oxide wear out even for stress at very low field. Therefore, it can be adopted as monitor of oxide degradation in ultrathin oxides where the traditional stress induced leakage current due to bulk-oxide traps is not detectable.
Retinal nerve fiber layer and ganglion cell complex thickness as a diagnostic tool in early stage dysthyroid optic neuropathy

Purpose To compare the diagnostic accuracy of peripapillary retinal nerve fiber layer with macular ganglion cell complex thickness as an auxiliary tool for the early diagnosis of dysthyroid optic neuropathy and help assess the effectiveness of the treatment. Methods In this retrospective case–control study, a total of 58 thyroid-associated opthalmopathy patients and 58 healthy participants were enrolled in the study. Thyroid-associated opthalmopathy patients were divided according to the European Group Graves’ Orbitopathy severity classification. The thicknesses of peripapillary nerve fiber layer and macular ganglion cell complex were measured using optical coherence tomography and their correlation with the severity of the disease as well as the effect of the treatment was investigated. Results No statistically significant differences were found between the mild thyroid-associated opthalmopathy group and the control group in both peripapillary nerve fiber layer and macular ganglion cell complex thickness. In the moderate-to-severe thyroid-associated opthalmopathy group, however, Temporal and Nasal peripapillary nerve fiber layer thicknesses were lower compared to the control group (p = 0.041, p = 0.012), whereas in the sight-threatening thyroid-associated opthalmopathy group Temporal Inferior, Nasal Superior, and mean (G) peripapillary nerve fiber layer thicknesses were larger (p = 0.000, p = 0.004, p = 0.000). No significant differences were observed in the macular ganglion cell complex thickness among the different severity groups and the control groups (p > 0.05). After treatment, the mean peripapillary nerve fiber layer thickness decreased whereas mean macular ganglion cell complex thickness showed no significant change in the sight-threatening group. A correlation was established between exophthalmos, best corrected visual acuity, clinical activity score, disease course, and the mean peripapillary nerve fiber layer thickness. The area under curve analysis indicated that mean peripapillary nerve fiber layer thickness can be used as a powerful diagnostic tool in early stage dysthyroid optic neuropathy in thyroid-associated opthalmopathy patients. Conclusion Our study indicates that peripapillary nerve fiber layer act as an auxiliary tool for the early diagnosis of dysthyroid optic neuropathy and helps assess the effectiveness of the treatment.
