Published: March 2022

Abstract
In this paper, the nonlinear finite element analysis by ABAQUS was used to predict the behavior and ultimate capacity of shaft lining steel-concrete composite structures. The numerical data for designing the shaft lining structure in coal mines; the stress-strain response and damage of steel-concrete composites is deeply explore through finite element analysis and analytical methods. The present work studies the influence of thickness-diameter ratio on the shaft lining structures performance by focusing on the stress-strain characteristics, geometry imperfections, damage and deformations occurs inside the materials structure properties. The results from the finite element simulation agree very well with the experimental observations, especially with regard to load-deflection response, crack patterns at different load stages, failure modes and stress-strain mechanisms. All these indicate that the constitutive models used for shaft linings concrete by ABAQUS are able to capture compressive behavior and stress-strain response of the different Z1, Z2, Z3, Z4, Z5, Z6, Z7, Z8, and Z9 specimens. The results show that the nine models have an acceptable agreement with the experimental results for stress-strain response and progressive damage with high reliability. In this paper the traditional bearing capacity calculation formula is also used to calculate the ultimate bearing capacity of the shaft lining structures. The finite element software ABAQUS is employed for modeling, analyzing and simulation of a new high strength composite for coal mining application design. Finally, the plastic strain, compressive damage variable, tensile damage variable, compressive stressstrain curves, and load-displacement diagrams are obtained at the same time verified by incremental loading method employed on ABAQUS for solving the rationality of the shaft lining structures bearing in finite element dynamic analysis.Based on the present research, for the studied cases, the experiment results of shaft linings concrete and FEM analysis by ABAQUS were in good agreement; the mean ratios of experimental-to-predicted values for: ultimate load capacities equal to 40 MPa; the limit loop strain of steel and concrete varying between 4000 to 6000 𝜇𝜀; the limit loop stress of steel is about 300 to 400 MPa, while for the concrete is about 150 to 200 MPa. Finite element analysis and experimental results show that, as loading progressed, the strain distribution in the shaft lining structure became approximately uniform indicating the formation of a tied arch mechanism. Concrete strain distribution is nonlinear and non-conform to Bernoulli’s assumptions for strain and stress distribution; this nonlinearity is due to the shear deformations inside the structural element. The study can provide certain reference for practical engineering calculation and analysis of compressive damage effects & stress-strain response of shaft lining structures.

Abstract
Background Chronic kidney disease (CKD) is a leading cause of death and premature morbidity. Exercise may potentially delay or prevent disease progression. We conducted a systematic review and meta-analysis of the effect of exercise in people with pre-dialysis CKD on functional ability, quality of life, renal parameters, cardiovascular risk factors and inflammatory markers.Methods We searched 7 major databases from January 2000 to November 2021, using key terms related to pre-dialysis CKD and exercise. Trials comparing the effects of exercise with a control group were pooled. Meta-analyses used a random effects inverse variance model. Results Twenty-six trials (860 participants) met the inclusion criteria. Significant improvements were identified in peak VO2 (2.85mL/kg/min, 95%CI:1.31,4.40; p=0.0003); the 6 Minute Walk (54.25m, 95%CI:29.65,78.85; p<0.0001), Timed Up and Go (-0.34, 95%CI:-0.57,-0.12; p=0.003), 2 Minute Step (57.48 steps, 95%CI:27.80,87.16; p=0.0001), and Sit To Stand tests (6.45 repetitions, 95%CI:1.18,11.72; p=0.02)]; Short Form [SF]-36 General Health (5.27, 95%CI:0.25,10.28; p=0.04); SF-36 Physical Component Summary (1.91, 95%CI:0.25,3.57; p=0.02); SF-36 Mental Component Summary (2.40, 95%CI:0.37,4.42; p=0.02)]; and waist circumference (-3.17, 95%CI:-4.44,-1.89; p<0.00001).Conclusions Exercise improved aerobic capacity, functional ability and quality of life in people with early CKD. Additional evidence is needed to determine if progression towards dialysis can be delayed.

Abstract

Crop residues potential for the bioeconomy is often limited under the basis of avoiding prospective soil organic carbon depletion. However, when processed in the bioeconomy the biomass carbon can be partially recovered in a stabilized degradation-resistant state in the coproducts. This study interlinks the theoretical basis between the coproducts’ characteristics and behavior in soils and the use of soil models to predict the effect of replacing crop residues with bioeconomy coproducts. Stemming from a revision of over 600 datasets we defined conversion coefficients from biomass C to coproduct (Cc) and their inherent recalcitrance in soils (CR) for pyrolysis (Cc: 48%, CR: 95%) and gasification biochar (Cc: 20%, CR: 95%), hydrochar (Cc: 31%, CR: 83%), digestate (Cc: 36%, CR: 68%) and lignocellulosic bioethanol solid (Cc: 44%, CR: 42%) and liquid (Cc: 21%, CR: 46%) coproducts. Different approaches to incorporate stabilized organic matter in soil models were investigated as well as the data requirements of a variety of soil models to set the basis for model adaptation in a dynamic harvest – return of C to explore future scenarios involving the coproducts return as a strategy to increase the bioeconomy feedstock provision while ensuring the maintenance of SOC stocks.

Abstract
Old, valuable trees (OVT) comprise an important urban ecological and cultural resource. Understanding their innate traits and driving factors can facilitate management, conservation and ecotourism development. This study assessed relationship between the species diversity composition, distribution, growth status, and tree-habitat of OVT in Wuzhishan City in Hainan Province, south China. We acquired tree and site data by field surveys, literature mining, interviews and laboratory tree-age determination. The results show that there are 216 OVT in Wuzhishan City, belonging to eight families and 13 genera and 21 species. Sapindaceae was the family with the largest number of species (79). Lychee was the predominant genus represented by Litchi chinensis. The overall age structure of OVT in Wuzhishan City is pyramidal, mainly concentrated in the range of 100-299a (average 163a). According to the grading norms of Chinese OVT, there are three Grade 1, 21 Grade 2 and 192 Grade 3 OVT. Tree height, trunk girth and crown width were normally distributed, mainly concentrated at ten-19 m (mean 32.1 m), 300-499 cm (mean 423 cm) and ten-20 m (mean 17 m), respectively. The overall number of individuals of OVT in Wuzhishan City was evenly distributed. The results of General Linear Model (GLM) analysis showed that the tree height of OVT in Wuzhishan City was highly significantly correlated with precipitation of wettest month (P=8.69E-04), trunk girth was highly correlated with annual mean temperature (P=9.30E-04) and precipitation of coldest quarter (P=3.06E-04), crown width was significantly correlated with mean temperature of warmest quarter (P=8.28E-03). The number of OVT in Wuzhishan City was significantly or highly significantly correlated with most environmental factors. In conclusion, Wuzhishan City has a rich variety of OVT with a uniform distribution; environmental factors have a greater impact on OVT, and it is recommended that targeted protection measures for OVT be developed in conjunction with the actual situation of the city.

Abstract
Although cities have risen to prominence as climate actors, emissions data scarcity has been the primary challenge to evaluating their performance. Here we develop a scalable, replicable machine learning methodology for evaluating the mitigation performance for nearly 50,000 local and municipal actors in the European Union from 2001–2018. We find that participation in one of the largest voluntary transnational climate initiatives is associated with a 1.6 percent reduction in annual emissions. Overall, these cities representing 301 million inhabitants have reduced nearly 186 million tons of carbon dioxide emissions. Compared to only 35 percent of external cities that have reduced emissions, 84 percent of cities participating in transnational climate governance have reduced emissions over the same time period. Participating cities reporting emissions data on average have higher annualized per capita reduction compared to cities without reported emissions. These findings provide quantitative evidence urban climate governance initiatives’ effect on global climate mitigation.

Published: March 2022

Abstract
The ability of adsorbent prepared from by - product of agriculture for the removal of dye was investigated. This study was aimed at the use of citric acid modified Globimetula oreophila to remove copper from aqueous solution. The adsorbent was characterized by Scanning electron microscope (SEM) and Fourier Transform Infrared (FTIR). The parameters investigated are the following: effect of pH, point of zero charge, initial copper concentration, contact time, kinetics and the effect of temperature. The optimum pH of adsorption was 5.2. Adsorption capacity increases gradually with increase in mass of biomass. The adsorption capacity decreased with increase in the initial copper concentration. 93% of the adsorption capacity was achieved in 15 minutes of contact time. The maximum adsorption capacity at equilibrium is 18.5 mg/g. The Dubinin–Radushkevich model was the most appropriate in describing the adsorption process. The Pseudo- second order kinetic model was suitable for explaining the adsorption of copper onto modified Globimetula oreophila. Thermodynamic properties related to the adsorption process were determined to be endothermic for the enthalpy change (36.3 kJmol-1), spontaneous (ΔG = -ve), and there was disorderliness at the adsorbent - adsorbate interface. The adsorption process was physisorption. Citric acid modified Globimetula oreophila is a promising adsorbent for the removal of copper from waste - water.
Spin Cross-Correlation Experiments in an Electron Entangler

Published: March 2022

Abstract
Correlations are fundamental in describing many body systems - not only in natural sciences. However, in experiments, correlations are notoriously difficult to assess on the microscopic scale, especially for electron spins. Here, we demonstrate a direct measurement of the spin cross-correlations between the currents of a Cooper pair splitter, an electronic device that emits electrons originating from Cooper pairs in a superconductor. While it is firmly established theoretically that these electron pairs form maximally spin-entangled singlet states with opposite spin projections, no spin correlation experiments have been demonstrated so far. We use ferromagnetic sidegates, compatible with superconducting electronic structures, to individually spin polarize the transmissions of two quantum dots fabricated in the two electronic paths, which act as tunable spin filters. The signals are detected in standard transport and in highly sensitive transconductance experiments. We find that the spin-cross correlation is negative, compatible with spin singlet emission, and deviates from the ideal value mostly due to a finite overlap of the Zeeman split quantum dot states. Our results demonstrate a new route to perform spin auto- and cross correlation experiments in nanometer scaled electronic devices, especially suitable for those relying on magnetic field sensitive superconducting elements, like unconventional, triplet or topologically non-trivial superconductors, or to perform Bell tests with massive particles, like electrons.

Abstract
The Productive SafetyNet Program (PSNP) is a major political ingenuity by governments and donors that makes millions of chronically food-deficient rural populations safer and more predictable from ongoing food relief. So, we will move mainly to cash-based social protection. This study aims at examining major features of Productive Safety Net Program and its impact on the livelihood of rural households in Doba District, Ethiopia. A multi-stage sampling technique was used to draw 220 sample respondents from PSNP beneficiaries and non-beneficiaries. Household survey, focus group discussions and key informant interviews were employed to collect quantitative and qualitative data. Data were analyzed using Propensity Score Matching (PSM) and binary logistic regression model. Results revealed that PSNP increased total annual income by 39% and calorie intake by 8.4% of the PSNP participant households compared to non-participant households. PSNP has positive and statistically significant effect on food consumption and total annual income and on the livelihood of farming households. The logistic estimator also revealed participation in PSNP was significantly associated with variables such as cultivable land size, livestock holding, house roofing materials, distance from the extensions’ office and access to credit service.

Abstract
Background
Aerobic capacity is crucial for the performance of soccer players. However, the relationship between aerobic capacity and the running performance of visually impaired soccer players is not clear.
Aims
The aims of this study were: (a) to determine the differences of lab measured VO2max between athletes and sedentary with visual impairment (VI); and to assess the relationship between lab measured VO2max of soccer players with VI (b) with the total distance that was covered in a soccer match and (c) with physiological parameters during soccer match.
Methods
Six male soccer players with VI and six male sedentary people with VI participated in this study. An analyzed match running performance of the six soccer players during soccer matches took place using a global positioning system. VO2max of all the participants was measured in a laboratory.
Results
Soccer players’ weight was 33% lower and their BMI was 23% lower than this of the sedentary men (p = .023, η2 = .457 & p = .038, η2 = .394 respectively). The relative with body mass VO2max of athletes was 42.9% higher in comparison with sedentary men with VI (p = .002, η2 = .755). No correlations were found between VO2max and match running performance (p = .679) and other parameters during the match in soccer players with VI.
Conclusions
The results demonstrate that soccer players presented more healthy anthropometric and physiological characteristics than sedentary people with VI. The match running performance depends on the tactical role of each player in the team and the rules of the match.

Published: March 2022

Abstract

With continued forest loss in tropical regions, it is important to understand whether and how public policies influence deforestation rates. One potentially important policy is Brazil’s “Native Vegetation Protection Law” (NVPL), passed in 2012 and popularly known as the New Forest Code. The goal of the law is to prevent forest loss; however, its success at maintaining forest is unclear. We analyze the effectiveness of the law in the state of Amazonas, Brazil by measuring forest loss in 2009 and 2012, pre implementation of the new vegetation protection law (NVPL) and comparing this to loss that occurred in 2015 and 2018, post-NVPL, in Settlement Projects (SP) affected by NVPL and Indigenous Lands (IL) and State/National Forests which were not under the mandate of the NVPL. We used these last two categories as Control Areas. Forest loss was greatest in SP during both time periods relative to two other categories considered. Implementation of the NVPL did not reduce overall deforestation in SPs. However, it did keep deforestation within the 20% limit set by NVPL in 31 of 35 SPs surveyed. In addition, forest cover decreased in only a few SPs. The variable with the strongest influence on deforestation within SP and IL was intensity of human land use in surrounding areas. We also found that IL and CU categories play an important role in maintaining overall forest cover.

Abstract
Background
Hepatitis B virus (HBV) is a major healthy problem worldwide. Because of the narrow host range of HBV, relative research was hampered by lacking of an appropriate animal model. The natural history of woodchuck hepatitis virus (WHV) infection in woodchuck is highly similar to that of HBV infection in human. Therefore this animal may be an valuable species for establishing an in vivo and in vitro HBV infection model to evaluate HBV DNA vaccines and anti-HBV drugs. Sodium taurocholate cotransporting polypeptide (NTCP) is the functional receptor for HBV and hepatitis D virus (HDV) infection. Considering that HBV cannot successfully infect woodchuck cells possibly due to the difference of the functional domain between woodchuck NTCP (wNTCP) and human NTCP (hNTCP), therefore, we tried to make woodchuck hepatocytes susceptible to HBV infection by replacing wNTCP with hNTCP .
Methods
The sequences alignment showed the functional domain of hNTCP related to HBV binding and entry process was different from wNTCP. In this study, hNTCP was introduced into the woodchuck hepatocytes by different approaches including transduction of vLentivirus-hNTCP in woodchuck hepatocytes, transfection of plentivirus-hNTCP-eGFP plasmids in woodchuck hepatocytes, as well as transduction of vAdenovirus-hNTCP-eGFP in woodchuck hepatocytes, in an attempt to make the woodchuck hepatocytes susceptible to HBV. After check the expression of hNTCP by immunofluorescence, the hNTCP-expressed woodchuck hepatocytes were then used to test its susceptibility to HBV infection, which was evaluated by secreted HBeAg in the supernatants. In order to determine whether these hNTCP-expressed hepatocytes could be infected by HDV, the established vAdenovirus-hNTCP-eGFP transduced woodchuck hepatocytes were subsequently subjected to HDV infection, and HDV viral genome was quantified by real-time PCR.
Results
hNTCP was successfully introduced to the woodchuck hepatocytes by using above three different methods. However, hNTCP-expressed woodchuck hepatocytes could not be infected by HBV. Nevertheless, we found that woodchuck hepatocytes containing hNTCP were sensitive to HDV infection.
Conclusion
This study indicating that there exist some other key factors mediate the HBV infection at early stage which have strict species specificity, and hNTCP is not the only determinant needed for HBV successful infection.
REA: Resource Exergy Analysis - A basic guideline for application focusing on energy systems evaluation
Authors: Jentsch Andrej 
Published: March 2022

Abstract
Evaluating energy systems using resource exergy analysis (REA) is key to ensure that climate targets are reached in time.The reason for this effect is wastefulness. Wastefulness in otherwise GHG-free energy systems increases the amount of GHG-free energy supply required to cover a considered demand. That means that less GHG-free energy converters are available for the rest of the energy system and overall fossil fuel use is increased.REA allows to assess wastefulness comprehensively and thus obtain a key indicator in addition to GHG emissions, that is grounded in science, namely resource exergy consumption.This publication provides a basic guideline to the application of resource exergy analysis (REA) with a focus on energy systems evaluation.REA is a well-tested application of exergy analysis to the field of technology comparison that can replace the less comprehensive Primary Energy Analysis and reduce the risk of suboptimal decisions.

Published: March 2022

Abstract
The Halda River of Chattogram is an icon being the only tidal river supporting the spawning of the genetically pure major Indian carp species. Halda is declared as the Bangabandhu Fisheries Heritage due to the broader support for movement towards its conservation. Discrete studies addressed water quality, land-use changes, ecosystem valuation, etc. without taking an integrated heritage conservation approach. This study aims to elucidate priority policy interventions for its integrated management by mapping significant constraints against Halda conservation. Published journal articles, newspaper reports, and reports on Halda from different organizations served as secondary information sources. Primary data were collected using structured questionnaires from 132 respondents from the egg collectors, tobacco farmers, and the rubber dam irrigation project users living in three Upazilas adjacent to the Halda River – Manikchhari, Hathazari, and Raozan. Key informant interviews were taken from the professionals of government and non-government institutions and researchers. Egg collectors appreciated the Upazila administration (65%) and the Department of Fisheries (48%) as effectively working institutions. Administrative bodies marked pollution (73%) as the main challenge in Halda conservation. Based on findings, recommendations were made which may assist the policymakers in developing strategies for integrated management of the river.
