Abstract
Background: Injury prevalence data, muscle strength, and fatiguability have shown differences between males and females. In addition, arm spatial orientation affects muscle activation and strength of the shoulder muscles, but little to no research has been conducted in relation to the shoulder rotator muscles comparing men and women. Therefore, the main aim of of this study was to perform a comparative investigation between two arm spatial orientations (45⁰ and 90⁰ of abduction in frontal plane) during a fatigue assessment of shoulder internal rotator (IR) and external rotator (ER) muscles. Secondly, the interaction of gender and dominance with muscular performance was assessed.Methods: Forty healthy sedentary participants, 20 males and 20 females took part in this study. Participants performed a fatigue resistance protocol consisting of 30 consecutive maximal concentric contractions of the IR and ER shoulder muscles in a supine position at a speed of 180⁰/s. The upper limb was abducted to an angle of 45⁰ or 90⁰ in frontal plane and each subject was tested on dominant and nom-dominant side, counterbalanced in order of administration. Performance measures of Induced Fatigue (IF), Cumulated Performance (C.Perf) and Best repetition (BR) were calculated and used for further analysis.Results: There was a significant difference in angle, with higher values observed in 90⁰ of abduction compared to 45⁰ of abduction for C.Perf by 6% and 7% for BR (P < 0.0005) in the ER. The dominant arm was significantly higher than the non-dominant arm for C.Perf with higher values of 9.7% at 90⁰ of abduction compared to 45⁰ of abduction (P = 0.017) and BR with higher values of 4.2% at 90⁰ of abduction compared to 45⁰ of abduction (P < 0.0005) in the ER in males. There was a significant difference in muscle group, with higher values observed in the IR for C.Perf (88.2%), BR (22.5%) and IF (36.9%); at 90⁰ of abduction compared to 45⁰ of abduction in males (P < 0.0005). Significantly higher values were observed for C.Perf in females between the dominant and non-dominant arm for the IR and ER (P < 0.0005). The females showed significantly lower values for C.Perf (47.74-55.10%) and BR (47.30-53.41%) in both muscle groups, both testing positions and in both limbs, when compared to males (P < 0.05)Discussion: It was established that an increase in the abduction angle will influence the strength of ER muscles in favour of the 90° angle without any differences observed in IR muscles. Males were found to produce approximately double the amount of work done compared to females, but the amount of induced fatigue was no different between both groups. Conclusion: Therefore, these findings are useful for clinicians throughout the monitoring of rehabilitation programs in sedentary individuals following shoulder injuries.

Abstract
The upper and lower seam of seam No.3 of some coal mines in Shandong Province are in close proximity which can be regards as close-distance coal seam mining.This paper takes the close-distance working face of Fucun coal mine as engineering background and mainly focuses on the investigation and research on inaccuracy of the forecasting and incompetence of the developing principles of water-flow fractured zone(WFFZ)during close-distance coal seam group mining.First,calculations on the height of WEEZ by adopting empirical formula.And FLAC3D software was established to calculate the height of the overburden WFFZ after repeated mining of the upper and lower seam of seam No.3.At the same time,using the double-ended water plugging observation technology of downhole drilling and upward hole drilling by analyzing the water injection loss ratio of the reference hole and the post-mining hole,the accurate numerical values of the WFFZ and the ratio of WFFZ height to mining height(W-M ratio)are obtained.The comparative analysis shows that the numerical simulation results are close to the measured ones,and the empirical formula is not applicable to the near-distance repeated mining.Finally,the prediction model is established based on the measured height of the WFFZ of multiple working faces,which provides a scientific basis for further exploring the development law of the overlying rock in underwater coal mining and ensuring the safe mining of coal seams at close distances.

Abstract
The research of unloading response characteristics of caverns with weak structure has important engineering value for the development and construction of underground space. In this paper, firstly, the cross fault cavity model is established based on particle flow code (PFC) software, considering different fault dip angles. The parallel bond model (PBM) is used in the cavern model and the smooth joint model (SJM) is used in the fault model. Then, the mechanical, acoustic emission (AE), energy response characteristics and failure modes of the cavern model with different fault angles are explored. The research result show that the fault angle has a great influence on the stress distribution and failure modes of surrounding rock.The existence of faults does not change the overall law of AE evolution curve, that is, the number of AE hits increases first and then decreases. However, the existence of faults changes the maximum number of AE hits and the duration of AE. When the cavern is unloaded, the strain energy of the model first decreases and then increases.

Abstract
BackgroundThis paper describes the process and results of a health promotion intervention to engage lay communities using telephone and online communication, to improve their current responses to the spread of COVID-19. MethodsAn intervention was conducted from March to July 2020 in three districts of Sri Lanka. Seven ‘trigger’ stories were shared through telephone or online communication to stimulate brainstorming and engage selected community members in repeated discussions to identify, prioritise and implement what they too agreed were potentially beneficial actions. The process was monitored, outcomes evaluated monthly and activities modified according to ongoing observations. ResultsA total of 638 families (both adults and children) involved themselves actively in implementing useful actions, and reported an increased sense of personal control. Potential risk groups, best feasible community safety precautions and preparation to face challenges in the event of infection reaching their community were identified during brainstorming sessions with community mobilizers. A majority reported that they felt more confident, united and less anxious about handling potential risks and problems. Other beneficial outcomes include lifestyle changes leading to healthier behaviours and a sense of greater control over the conditions that govern their lives. ConclusionUse of telephone and online communication were effective in generating desirable community changes.

Published: May 2021

Abstract
The dyes used in the textile industry contribute significantly to pollution of water sources as they are disposed, most of the time, without proper treatment. The objective of this work was to test three strains of two species of the genus Trametes collected in Brazil against the ability to discolor the indigo carmine dye and to detect the activity of the enzymes laccase, lignin peroxidase and manganese peroxidase. The experiment was carried out in Kirk medium under static, non-sterile condition, at ±28 °C for 120 h. Trametes lactinea (URM8350) discolored 81.40% of the indigo carmine dye, T. lactinea (URM8354) 85.09% and T. villosa (URM8022) 96.11%. Laccase was detected in all specimens. Manganese peroxidase was detected in T. villosa (URM8022) and T. lactinea (URM8354), while lignin peroxidase was not detected in any of the isolates under the conditions of the experiment. The discoloration rates observed demonstrate the ability of the strains to discolor carmine indigo and the promising use in the discoloration processes in wastewater from the textile segment.

Abstract
PurposeBlood from infarct-related arteries obtained by thrombus aspiration is good material for studying the local microenvironment of blood vessels in myocardial infarction. Here, we aimed to observe the effects of intracoronary microparticles (MPs) on cardiac fibrosis and to find associated microRNAs in MPs.MethodsBlood samples were collected from patients with ST-segment elevation myocardial infarction who underwent emergency percutaneous coronary intervention, and sub-supersonic centrifugation was used to separate the MPs.ResultsWe found that rats treated with intracoronary MPs showed better cardiac function after myocardial infarction compared with rats treated with PBS control or peripheral MPs. RNA microarray analysis indicated that microRNAs, especially miR-625-5p, may play a role in the process. Supplementation with miR-625-5p inhibited proliferation of cardiac fibroblasts and myocardial fibrosis in a mouse myocardial infarction model. ConclusionOur findings indicate that plasma MPs in infarct-related arteries in patients with acute myocardial infarction can inhibit myocardial fibrosis and improve cardiac function, with a process mediated by miR-625-5p and HMGA1 (high mobility group AT-hook 1). The current study may provide a possible reference for thrombus aspiration standard.

Published: May 2021

Abstract
Oscillatory base manipulators (OBMs) are a kind of mechanical systems suffering from unexpected base oscillations. The oscillations affect tremendously system stability. Various control methods have been explored, but most of them require measurement or prediction of the oscillations. This study is concerned with a novel OBM-the autoloader, which are used in modern, autonomous main battle tanks. The base oscillation of the autoloader is hard to be obtained in practice. Furthermore, control synthesis for autoloaders is complicated with intrinsic payload uncertainty and actuator saturation. To address these issues, a novel robust control scheme is proposed in this work relying on the implicit Lyapunov method. Moreover, a novel two-Degree-of-Freedom manipulator operating on a vibrating base is constructed to realize the proposed control. To the best of the authors' knowledge, this is the first study considering both control and hardware implementation for the OBM-like autoloaders. Experimental results demonstrate that, although without prior information of the base oscillation, the proposed controller exhibits good robustness against the base oscillation and payload uncertainty.

Abstract
Mexico City is one of the largest cities in the world and therefore there is a high generation of waste, of which 44% is equivalent to the Organic Fraction of Municipal Solid Waste (OFMSW). In this work, two case studies are evaluated for the application of biogas obtained in an anaerobic digestion process using OFMSW. CASE I considers obtaining biomethane, while CASE II considers energy cogeneration. The biogas yield was determined and was used to carry out an analysis of the process through an economic and environmental impact evaluation on different amounts of OFMSW (100-500 MT). The net present value of this project does not show the feasibility of the process, unless subsidy support is considered. The value of the smallest subsidy over the total investment to find NPV = 0, is 5.64 % for CASE I and 6.84% for CASE II at 200 MT of OFMSW. The WAste Reduction (WAR) methodology was used, which shows that the potential for environmental impact for the two cases is only 4%. The in-depth research of this work helps to maintain the anaerobic digestion process in a circular economy context, for the supply of energy and the protection of the environment.
Advances and Physicochemical Property Investigations by Methylene Chain Length of Perovskite-type Layer Crystals [NH3(CH2)nNH3]CdCl4 (n=2, 3, and 4)
Authors: Lim Ae Ran 
Published: May 2021

Abstract
Hybrid perovskites have potential applications in several electrochemical devices such as supercapacitors, batteries, and fuel cells. However, despite various potential applications, there have been limited studies on compounds containing Cd. Therefore, in this study, the structures and phase transition temperatures TC of organic–inorganic perovskite [NH3(CH2)nNH3]CdCl4 (n=2, 3, and 4) were confirmed by X-ray diffraction and DSC experiments. The thermal stabilities obtained by TGA and DTA results were considered as a function of the length n of the CH2 groups in the cation. In addition, structural characteristics and molecular dynamics of the cation and anion near TC were studied by 1H MAS NMR, 13C MAS NMR, 14N static NMR, and 113Cd MAS NMR experiments. From these results, regardless of whether n is even or odd, the differences in thermal and physical properties were minimal. Rather, the difference in molecular motion relative to the length of the cation was seen only at higher temperatures. These results provide insights into the thermal stability and molecular dynamics of [NH3(CH2)nNH3]CdCl4 crystals and are expected to facilitate potential applications.
COVID19 Vaccine Intentions in South Africa: Health Communication Strategy to Address Vaccine Hesitancy

Published: May 2021

Abstract
Background: Widespread vaccine acceptance is key to achieving herd immunity through vaccination against COVID19, especially because the available vaccines do not have 100% efficacy. The continued infection amongst the unvaccinated can lead to heightened risk of further virus mutation, exposing even those vaccinated to new virus strains. Therefore, there are social benefits in minimising vaccine hesitancy. The objective of this study is to assess the level of COVID19 vaccine hesitancy in South Africa, identify the socio-economic patterns in vaccine hesitancy and to develop a targeted health communication strategy based on the HBM and EPPM models in order to improve vaccine acceptance. Methods: The study uses the nationally representative National Income Dynamics Study - Coronavirus Rapid Mobile Survey (NIDS-CRAM) survey. The analysis combines univariate and bivariate statistics together with multivariate regression models like binomial/ordinal logit and seemingly unrelated regressions.Results: The study finds that vaccine acceptance is lower than that of non-pharmaceutical intervention life face-mask use. Only 55% are fully accepting of the vaccine, while a further 16% are moderately accepting of vaccines. Together, vaccine acceptance is estimated at 70.8% and vaccine hesitancy against COVID19 is estimated at 29.2% amongst the adult South African population. The reasons cited for vaccine hesitancy are primarily due to concerns regarding the side-effects and efficacy of vaccine. the study has identified perceived risk of infection with the mediating role of efficacy as a key predictor of vaccine intention. Apart from vulnerability to infection, those perceiving higher severity of risk (elderly and those with chronic illness) have lower hesitancy. Higher awareness of COVID19 related information and higher household income are correlated with lower vaccine hesitancy. The non-black African population group has significantly high vaccine hesitancy compared to black Africans. Males on average have lower hesitancy compared to females, and unmarried/unpartnered individuals are found to have higher hesitancy. Conclusions: There are other significant differences across socio-economic and demographic variables in vaccine hesitancy. From a communication perspective, it is imperative to continue risk messaging, hand in hand with clearer information on the efficacy of the vaccines

Published: May 2021

Abstract
Background: Although the incidence of myocardial bridge (MB) has been defined in different conventional coronary angiography (CCA) studies,the frequency of MB in radial access coronary angiography (RACA) is unknown.The aim of this study was to determine the incidence of MB in patients undergoing RACA.Method: A total of 2600 consecutive patients who underwent RACA were retrospectively investigated to detect the presence of MB.The clinical,laboratory, and angiographic features of the patients with MB were analyzed. Results: MB was detected at an incidence of 10.2%, in 255/2600 patients who underwent RACA.The most involved coronary artery was the left anterior descending artery (LAD) (86.9%) and the mid segment (84.9%) was the most affected section.Co-involvement of multiple coronary arteries by MB was 7.8%. Coronary artery disease (CAD) was determined in 102 (36.2%) of the coronary arteries with MB, 82.4% which were proximal to the MB.Conclusion: These data demonstrated that the incidence of MB able to be detected on RACA was much higher than reported in previous CCA studies.

Abstract
Cancer-associated fibroblasts (CAFs) participate in critical processes in the tumor microenvironment, such as extracellular matrix remodeling, reciprocal signaling interactions with cancer cells and crosstalk with infiltrating inflammatory cells. However, the relationships between CAFs and survival are not well known in lung cancer. The aim of this study was to reveal the correlations of CAFs with survival rates, genetic alterations and immune activities. This study reviewed the histological features of 517 patients with lung adenocarcinoma from The Cancer Genome Atlas (TCGA) database. We performed gene set enrichment analysis (GSEA), network-based analysis and survival analysis based on CAFs in four histological types of lung adenocarcinoma: acinar, papillary, micropapillary and solid. We found four hallmark gene sets, the epithelial-mesenchymal transition, angiogenesis, hypoxia, and inflammatory response gene sets, that were associated with the presence of CAFs. CAFs were associated with tumor proliferation, elevated memory CD4+ T cells and high CD274 (encoding PD-L1) expression. In the pathway analyses, CAFs were related to blood vessel remodeling, matrix organization, negative regulation of apoptosis and transforming growth factor-b signaling. In the survival analysis of each histological type, CAFs were associated with poor prognosis in the solid type. These results may contribute to the development of therapeutic strategies against lung adenocarcinoma cases in which CAFs are present.

Published: May 2021

Abstract
Background: Patient satisfaction and expectations are now recognized as an outcome measure for successful total knee arthroplasty (TKA). The purpose of this study was to determine which factors including soft tissue balance during surgery affect patient satisfaction and expectations after TKA.Methods: A total of 135 patients (157 knees) with knee osteoarthritis who underwent primary TKA with a posterior stabilized design were studied. After implantation of all components, varus/valgus laxity of the knee was measured intraoperatively with the knee at 0°, 30°, 60°, 90°, and 120° guided by an image-free navigation system. Factors that affected patient satisfaction and expectations, including lateral and medial laxities, were evaluated using the 2011 Knee Society score.Results: The mean intraoperative lateral laxity was 1.1°, 1.6°, 0.9°, 1.3°, and 1.7° with the knee at 0°, 30°, 60°, 90°, and 120°, respectively. The mean intraoperative medial laxity was 1.1°, 1.4°, 1.1°, 1.1°, and 1.7° with the knee at 0°, 30°, 60°, 90°, and 120°, respectively. Patient satisfaction after TKA correlated positively with symptom (R = 0.61, P < 0.01) and functional activity (R = 0.47, P < 0.01) scores. Patient expectations after TKA correlated positively with symptom (R = 0.29, P < 0.01) and functional activity (R = 0.20, P = 0.01) scores, and negatively with medial laxity at 30° (R = -0.21, P < 0.01).Conclusion: Midflexion medial laxity was associated with worse patient expectations after TKA. Avoiding medial laxity could be one of the important techniques during TKA.

Abstract
Considerable uncertainty and debate exist in projecting the future capacity of forests to sequester atmospheric CO2. Here we generate spatially explicit patterns of biomass loss by mortality (LOSS) from a dataset (n = 2676) of long-term (1951 to 2018), largely unmanaged forest plots to constrain projected (2015–2099) net primary productivity (NPP), heterotrophic respiration (HR) and net carbon sink in six dynamic global vegetation models (DGVMs) across North and South America, Africa, Asia, and Australia. This approach was motivated by the higher accuracy of field-derived LOSS estimates and the strong relationship among LOSS, NPP, and HR at continental or biome scales. The field observations showed higher values of LOSS in tropical regions (0.53 Kg m− 2 y− 1) than in North America (0.22 Kg m− 2 y− 1). The upscaled gridded LOSS map show hotspots in Southern Asia & Australia, Northwestern South America, and the western coast of North America. The DGVMs overestimated LOSS, particularly in tropical regions and eastern North America by as much as 0.5 Kg m2− y1. The spread of DGVM-projected NPP and HR uncertainties was substantially reduced after constraining the simulations with the observed LOSS patterns. The observation-constrained models show a decrease in the tropical forest carbon sink by the end of the century, particularly across South America (from 2 to 1.3 PgC y1), and an increase in the sink in North America (from 0.75 to 0.97 PgC y1). These results suggest that forest demographic data can be used to constrain land carbon sink projections.
