Published: September 2022

Abstract
Objective: As current periviable survival calculators account for only five characteristics, this study aimed to create a predictive calculator for periviable infant survival that accounts for any variable associated with survival.
Study Design: US population-based cohort study of livebirths between 22 0/7 – 25 6/7 weeks of gestation from 2009 through 2013 to identify factors associated with neonatal survival. Multivariate logistic regression estimated the association of factors on risk of survival with Hosmer-Lemeshow calibration for test of fit.
Results: Variables in the model by magnitude of influence were birthweight, gestational age, sex, antenatal steroid exposure, resuscitation, presentation, mode of delivery and multifetal gestation. Receiver operator characteristic (ROC) curve achieved AUC of 0.800 (95% CI 0.795-0.804), higher than presently available periviable calculators. External validation demonstrated a consistent measure of discrimination (AUC 0.800, 95% CI 0.790-0.809).
Conclusion: The calculator is available at https://stage.ob.tools/calc/elbw (username:elbw@ob.tools, password: personalizeCare) for use by health care providers in counseling women with threatening periviable birth.

Abstract

This study aims to provide researchers and practitioners with a more elaborate instrument to measure turnover intentions based on the planned behaviour theory model. The questionnaire assesses 5 distinct aspects of turnover intentions (i.e., subjective social status, organisational culture, personal orientation, expectations, and career growth). We demonstrate the reliability, factor structure, and validity evidence based on internal structure and relationship with other variables of the new measure among two samples (N1 = 622; N2 = 433). In total, the study indicates that the assessment can be used to reliably assess several major indicators of turnover intentions.

Abstract
Toxoplasma gondii, a highly prevalent obligate apicomplexan parasite, is important in clinical and/or veterinary medicine. Based on its virulence in laboratory mouse strains, T. gondii is divided into three lineages. In this study, we examined and compared the distributions of the glycerophospholipids phosphatidylserine (PtdSer) and phosphatidylethanolamine (PtdEtn) and a glycosphingolipid GM3 in type I RH and type II PLK strains of T. gondii (highly and moderately virulent phenotypes, respectively). The gold labeling density of PtdSer in the exoplasmic leaflet (EF) of the inner membrane complex (IMC) in the RH strain was significantly higher than that in the PLK strain. PtdEtn labeling was significantly higher in the EF than in the cytoplasmic leaflet (PF) of the middle and inner IMC membranes in the RH strain. In contrast, PtdEtn labeling was low in the PLK strain. The gold labeling density of GM3, localized in the EF of the IMC membrane, was much higher in the RH strain than that in the PLK strain. GM3 is a major raft component and both PtdSer and PtdEtn affect the maintenance of raft microdomains, which are important for gliding motility when T. gondii enters mammalian host cells. Raft microdomains have significant roles in the virulence of T. gondii. Therefore, we suggest that the PtdSer and PtdEtn expression levels are correlated with the virulent phenotypes of T. gondii. Furthermore, we demonstrated that PtdSer was absent in the PF of the inner IMC membrane but present in the PF of the middle IMC membrane. This suggests that a barrier-like mechanism that prevents the diffusion of PtdSer exists in the PF between these two membranes.

Abstract
The Ria de Aveiro is an important coastal lagoon for wildlife in Portugal, where the production of bivalves reaches approximately 2700 tonnes annually. However, the illegal overfishing of bivalves is frequent in this lagoon, which causes critical changes in the ecosystem. In this study, using a developed food-web model (Ecopath model), the ecological carrying capacity and maximum sustained yield of bivalve filter feeders were estimated, and further increases in bivalve biomass in other species groups were investigated. The results showed that 1) the current biomass and legal catch of bivalves do not yet exceed the ecological carrying capacity (177.84 tonnes km− 2) or the maximum sustained yield (88.92 tonnes km− 2 year− 1) in Ria de Averio; 2) the harvested bivalves of the maximum sustained yield represent removing from the ecosystem ~ 581 tonnes carbon (C) and ~ 83 tonnes nitrogen (N) annually, with substantial ecological and economic implications; and 3) a further increase in the biomass levels of bivalves may cause the ecotrophic efficiency of other groups to become unrealistic, potentially leading to decreases in ecosystem transfer efficiency, biodiversity and health. The results here are expected to guide the sustainable development and management of bivalves in Ria de Averio and the protection of the local environment.

Published: September 2022

Abstract
Genetic diversity is considered to be necessary for the long-term survival of species as it enables environmental adaptations to increase a species' or population's chances of survival, but it is being threatened by several environmental changes and anthropological interventions. Five microsatellite markers were employed to analyze the genetic diversity of Oreochromis mossambicus (Mozambique Tilapia) from River Jhelum. Average values of allelic number (Na) and allelic richness (Ar) ranged from 2.40 to 3.60. The average observed (HO) and expected heterozygosity (He) values ranged from 0.55 to 0.69 and 0.54 to 0.67, respectively. The inbreeding coefficient FIS values showed the highest level of inbreeding in Rasool Barrage and lowest in Pind Dadan Khan. Significant departure from HWE was observed in 3 out of 25 tests. The AMOVA specified that majority of variation (87.050%) was attributed to “within individuals”. UPGMA dendrogram revealed that PDK, RB, MD and JB populations were highly related, while THW appeared to differ significantly from other populations. The findings of this research will be helpful for the management of the concerned populations to maintain their genetic quality in in Pakistan.

Abstract
Although VB-Group transition metal disulfides (TMDs) VS2 nanomaterials with specific electronic properties and multiphase microstructures have shown fascinating potential in the field of electromagnetic wave (EMW) absorption, the efficient utilization of VS2 is limited by their environmental instability and sole electromagnetic (EM) loss mechanism. In order to fully exploit the maximal utilization values of VS2 nanomaterials for EMW absorption through mitigating the chemical instability and optimizing the EM parameters, biomass-based glucose derived carbon (GDC) like sugar-coating has been decorated on the surface of stacked VS2 nanosheets via a facile hydrothermal method, followed by high-temperature carbonization. As a result, the modulation of doping amount of glucose injection solution (Glucose) could effectively manipulate the degree of GDC coating on VS2 nanosheets, further implementing the EM response mechanisms of the VS2/GDC hybrids through regulating the conductivity and constructing multi-interface heterostructures, as reflected by the enhanced EMW absorption performance to a great extent. The minimum reflection loss of VS2/GDC hybrids could reach -52.8 dB with a thickness of 2.7 mm at 12.2 GHz. Surprisingly, compared with pristine VS2, the VS2/GDC hybrids have the effective absorption bandwidth (EAB) increased from 2.0 to 5.7 GHz, while their environmental stability is much enhanced because of GDC. Obviously, this work provides a promising candidate to realize frequency band tunability of EMW absorbers with exceptional performance and environmental stability.

Abstract
The study aims to enriched ogi using Aduwa defatted protein meal and protein concentrate at 16% protein target inclusion (ogi control only, ogi + 16% protein inclusion with defatted Aduwa protein meal and 16% inclusion with Aduwa protein concentrate. Enrichment of ogi with aduwa proteins significantly (p<0.05) improved the proximate phytochemical and functional properties of the mix while a reverse trend was found for sensory properties.. The protein, fat, crude fibre, ash, bulk density, water absorption capacity, oil absorption capacity foam capacity, percentage dispersibility and total phenolic content of the enriched mix were significantly (p<0.05) higher as compared to control-ogi. The sensory parameters namely colour, texture, mouthful, aroma, appearance, and general acceptability of DAPM-ogi and APC-ogi were significantly (p<0.05) lower than the control-ogi (100% maize ogi). Further, DAPM -ogi and APC-ogi enriched meals were brown in colour and a flouring mix, the sensory appraisal revealed that the control - ogi without enrichment received high sensory scores comparable to the enriched mix samples. The physiochemical and anti-nutrients analysis revealed that enriched DAPM-ogi and APC-ogi are rich in nutrients and are safe.

Abstract

The effect of alloy composition and oxidation condition on specific mass gain of FeCrAl alloys was studied and analyzed using a combination of experimental and AI approaches. A Neural Network (NN) classification model was used on the experimental FeCrAl dataset produced at GE Research from steam oxidation studies at both high (~ 1000°C) and low temperature (~ 400°C). Furthermore, using the Shapley Additive exPlanations (SHAP) explainable Artificial Intelligence (XAI) tool, we explore how the NN can identify an alloy at specific oxidation condition to form a protective oxide or not. We found high Al and Cr concentration increases the chances of forming protective oxide layer, which is consistent with literature studies. Contrary to Al and Cr, the presence of Mo in FeCrAl creates thick unprotective oxide scale that results in high mass gain per unit area.

Abstract
There is growing evidence of increasing pollution threats to groundwater resulting from anthropogenic activities. Assessments of the risk of groundwater contamination are useful for preventing and controlling groundwater pollution. This study established a quantitative evaluation model based on the origin–pathway–target model. The target, guideline, and indicator layers were established through a comprehensive analysis of the distribution of pollution sources, hydrogeological conditions, and other conditions in the northeastern plain area of Beijing by applying the hierarchical analysis method. Each assessment index was quantified and analyzed based on the groundwater pollution risk assessment index system, and the risks associated with pollution sources, groundwater susceptibility to pollution, and groundwater value in the study area were evaluated. The comprehensive assessment results were superimposed by the matrix method and the pollution risk classification was conducted using the ArcGIS platform. Grade Ⅰ to Ⅴ pollution risk areas accounted for 12.5%, 28.5%, 23.2%, 26.1%, and 9.7% of the total area, respectively. The V pollution risk area was mainly in the central and northeastern part of the Beijing plain area and agriculture and industry were the main sources of pollution in the central and northeastern areas, respectively. The study area had a large net recharge, soils were dominated by sand and gravel, and there was a high permeability coefficient. The study area also showed poor groundwater pollution prevention performance, which resulted in the infiltration of pollutants into the groundwater environment. The V pollution risk area contained sensitive groundwater targets, and the pollution index, groundwater richness, annual average groundwater extraction, and risk of pollution were high.

AbstractThere is overwhelming evidence that the shallow water stocks of Lake Malawi have been noticeably overexploited by both the artisanal and commercial trawl fishers. However, there have been some recent initiatives to restore these areas such as enhancing monitoring, control and surveillance, revamping local fisheries management authorities and establishments of community managed fish protected areas. Yet, information evaluating the impacts of such interventions on the fish stocks is limited. This information is critical for fisheries management and planning. Therefore, a study to reveal the current status of Chambo (Oreochromisspecies) and other shallow water fish stocks of the southwest arm (SWA) and southeast arm (SEA) of Lake Malawi was conducted. The study compared the status of fish stocks in the two arms using stock abundance and biodiversity indicators. Results indicated similar fish species diversity in the two arms. Overall, Chambo (Oreochromis spp.) was among the top ten fish that contributed a significant amount of weight to the total sampled catch. The SWA and SEA reported average catch rates of 77.4±22.6Kg/0.5hr and 177.7±18.4Kg/0.5hr, respectively whereas Chambo registered mean catch rates of 61.0±8.1Kg/0.5hr and 68.0±13.7Kg/0.5hr, respectively. Overall fish densities for all fish species in the SWA and SEA were estimated at 2.9tons/km2and 3.5tons/km2, respectively. Chambo density estimates for both SWA and SEA were calculated as 1.1tons/km2 and 1.2tons/km2, respectively. A total biomass of 10, 722 tons was estimated in both regions with the SEA contributing 57% while the biomass estimates of Chambo was 3,964 tons of which 54% was registered in the SEA. A decline in fish stocks in the shallow waters was observed and masks the efforts that the Government is doing to ensure the restoration and sustainability of fish stocks in the areas. It is therefore strongly believed thatregulating mesh sizes, limiting fishing effort and protecting critical breeding habitats are critical in reversing the observed trends.

Abstract

Chile, the world's largest copper producer, generates massive amounts of mine tailings that are a source of ongoing environmental concern for local communities. The main objective of this work is to evaluate the concentration of elements: As, Cd, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Zn and SO42- in soils, water, and vegetation in the communities surrounding a mine tailings dam in central Chile. Soils, waters and plants samples were collected from the towns of Chacabuco, Huechún, Huertos Familiares, Punta Peuco and Santa Matilde, which are located at 3 to 8 km from the Ovejería mine tailings site, operated by CODELCO in operation since 1999. The results showed that the levels of metals/metalloids and SO42- in water (pH 6.69–7.95) met both WHO limits and Chilean water quality standards for miscellaneous uses. In soil (pH 7.67–8.39), total and available concentrations of metals/metalloids did not exceed common international reference values. Plants with acceptable levels of metals and S were Citrus limon, Eucalyptus, Schinus molle, Prunus persica, Medicago sativa, Citrus sinensis, and Ficus carica. The only species with a content of one metal (Fe) well above the reference value and high concentrations of other metals (Cu, Mn, Mo, and Pb) was Acacia caven. The concentrations of chemical elements determined between 2015–2018, in soils, water and plants in different locations near the active copper tailings dam Ovejeria, in Central Chile, allow us to conclude that in general the levels are comparable to national and international references and do not indicate contamination.

Published: September 2022

Abstract
Background: The aim of the study was to compare the delayed potentiation (DLP) effects induced by cluster sets (CS) versus traditional sets (TS) resistance training.
Methods: Sixteen male collegiate athletes were recruited for the study in a crossover design. All the subjects performed a CS (30 s interval between reps, 4 minutes interval between sets) and a TS (no rest between reps, 4 minutes interval between sets) resistance training sessions (3 sets of 3 repetitions of barbell back squat at 85% 1RM) in random order separated by 72 hours. Countermovement jump (CMJ), 20-meter sprint and T-test performance were evaluated at baseline and 6 hours after the resistance training sessions.
Results: 6 hours after the resistance training sessions, both the CS and TS significantly improved the CMJ height (CS: ES = 0.48, P < 0.001; TS: ES = 0.23, P = 0.006), CMJ take-off velocity (CS: ES = 0.56, P < 0.001; TS: ES = 0.38, P = 0.004), CMJ push-off impulse (CS: ES = 0.38, P < 0.001; TS: ES = 0.26, P = 0.006), 20-meter sprint (CS: ES = 0.85, P < 0.001; TS: ES = 0.58, P = 0.006) and T-test (CS: ES = 0.99, P < 0.001; TS: ES = 0.73, P = 0.003) performance compared with baseline values. Following the CS, CMJ height (ES = 0.25, P = 0.007), CMJ peak power (ES = 0.2, P = 0.034) and 20-meter sprint performance (ES = 0.31, P = 0.019) were significantly better compared with that following TS.
Conclusions: Both TS and CS configurations could induce DLP at 6 hours following the training. CS is a better strategy to induce DLP compared with TS training.
Massive and massless plasmons in germanene nanosheets

Published: September 2022

Abstract
Atomically thin crystals may exhibit peculiar dispersive electronic states equivalent to free charged particles of ultralight to ultraheavy masses. A rare coexistence of linear and parabolic dispersions yields correlated charge density modes exploitable for nanometric light confinement. Here, we use a time-dependent density-functional approach, under several levels of increasing accuracy, from the random-phase approximation to the Bethe-Salpeter equation formalism, to assess the role of different synthesized germanene samples as platforms for these plasmon excitations. In particular, we establish that both freestanding and some supported germenene monolayers can sustain infrared massless modes, resolved into an out-of-phase (optical) and an in-phase (acoustic) component. We further indicate precise experimental geometries that naturally host infrared massive modes, involving two different families of parabolic charge carriers. We thus show that the interplay of the massless and massive plasmons can be finetuned by applied extrinsic conditions or geometry deformations, which constitutes the core mechanism of germanene-based optoelectronic and plasmonic applications.
Research on rock movement control method in underground mining based on the action of granular lateral pressure
Authors: Zhang Dongjie , Liu Zeyu , Liu Shuxin , Liu Yang 
Published: September 2022

Abstract
Lateral pressure provided by caving rocks plays an important role in keeping the stability of the sidewall rock mass and controlling the rock movement. Taking Xilinhot Fluorite Mine as an engineering background, we studied the control mechanism of the granular media lateral pressure on the rock movement by combining physical experiments, theoretical analysis and field monitoring. The results indicated that with the increase of the granular media depth, the lateral pressure provided by the static granular media presented two stages of rapid growth and slow growth. The lateral pressure on the footwall was negatively correlated with the dip angle of the orebody, and the lateral pressure on the hanging wall was positively correlated with the dip angle of the orebody. Ore drawing only caused the granular media lateral pressure near the drawing point to decrease. As the granular media moved, the granular media lateral pressure outside the pressure reduction area further increased, and this part of the granular media would play a key role in limiting surface rock movement. On this basis, the improved calculation formula of GLMP was given, which could be better applied to calculate the GLMP and critical granular media column with different dip angles. The action mechanism of the GLMP in the control of the surface rock movement was clarified. The granular body in the collapse pit was mainly composed of three parts: the bottom loose granular media column, the middle compaction granular media column and the upper critical granular media column. The critical granular media column was the most important area to control surface subsidence and rock movement. Finally, through field practice, after effective filling of the collapse pit, the surface vertical displacement of the hanging wall and footwall was decreased by 56.8% and 55.6%, respectively, and the control effect of surface rock movement was remarkable.
