The increased land-use change (LUC) from native lands to other land use at the Conoor region of western ghats in Tamil Nadu has severely declined soil carbon concentration. Therefore to quantify this decline, Carbon Management Index (CMI) was worked out under major land uses {(Forest (FOR), cropland (CRP), tea plantation (TEA)} using total organic carbon (TOC) and carbon pools under varying degrees of lability {a) NLC (non-labile carbon) b) VLC (very labile carbon) c) LC (labile carbon) d) LLC (less labile carbon)}. Results portray that the carbon pools were significantly (p < 0.05) higher in FOR than in TEA and CRP. The contribution of active pools {(very labile carbon (VLC) and labile carbon (LC)} towards TOC was higher in TEA and CRP, whereas in FOR, the passive pool {(less labile carbon (LLC) and non-labile carbon (NLC)} was higher. TOC (0-45 cm) was concentrated on the surface soils of FOR (32.88 g kg-1), CRP (11.87 g kg-1) and TEA (18.84 g kg-1) and it gradually declined with the increase in depth. The decline in TOC was maximum between 0 – 15 and 15 – 30 cm depth in CRP (30.62%) and FOR (22.17%), whereas it was maximum (37.16%) between 15 -30 and 30 -45 cm depth in TEA. Therefore, LUC spotlights the degradation of carbon pools and its extent was quantified using the carbon management index (CMI). The CMI (0 – 45 cm) recorded at CRP (12.93) and TEA (32.62) signals the need for an implementation of carbon management strategies at Conoor to keep the soils alive and protect biodiversity.

The enzyme amylase is one of the most important in biotechnology, and lipase operates as a catalytic agent for a broad range of hydrolytic and synthetic activities. This study aimed to assess the optimization of amylase and lipase enzyme produced by microorganisms isolated from selected waste or garbage dumpsite in Akure, Ondo State Nigeria. The isolates were identified using biochemical and cultural characteristics. A total of seven bacterial isolates were identified and quantitative production of amylase and lipase by solid-state fermentation was assessed for each bacterial isolate. The optimization of nutritional and environmental parameters on enzymes produced by the isolated organisms was standardized with respect to incubation time, temperature, pH, and carbon and nitrogen sources. The activity of the enzymes generated was determined by spectrophotometric assay. Of the seven organisms isolated, Bacillus cereus LA326 and Bacillus subtilis AU021 had the highest amylase and lipase activity and were therefore chosen for further research. The maximum level of amylase and lipase activity attained by B. subtilis AU021 was 68.0 mmol/min and 16.3 mmol/min after 18 hours of incubation respectively, while the maximum levels of amylase and lipase activity attained by B. cereus LA326 were found to be 76 mmol/min after 12 hours and 16.3mmol/min after 18 hours of incubation, respectively. The study found that B. cereus and B. subtilis isolated from dumpsites could be efficient producers of biotechnology-relevant enzymes and that environmental conditions could influence their enzyme production.

Published: September 2022

Soil heavy metal pollution is widespread and has severe adverse effects on soil organisms. Earthworms are the major soil organisms which perform several beneficial ecological functions butare vulnerable to damage from heavy metal pollution of soil. The present study was conducted to evaluate the potential toxicity of arsenic (As) and chromium (Cr) on the biochemical response of the earthworm, Eisenia fetida. Following exposure to various sub-lethal concentrations ofAs (34, 68, 102 and 136 mg/kg) and Cr(26, 51, 77 and 102 mg/kg ) for 28 days, the levels of several biochemical markers, including superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), Glutathione-S-transferase (GST) and malondialdehyde (MDA) content were assessed. The results showed that both heavy metals significantly (p<0.05) impacted the antioxidant enzyme activities and MDA content during the entire exposure period. Compared with the control, SOD, CAT, POD and GST activities increased significantly (p<0.05) by (6.21-23.23, 6.32-18.6, 15.87-34.18 and 0.84-5.45% respectively) at14th day, but after prolonged exposure, these activities were significantly (p<0.05) decreased (9.58-38.13, 10.09-30.03, 19.05-53.16 and 2.26-9.36% respectively) at 28th day. The contents of MDA showed significant (p<0.05) increase (17.84-45.59%) in all exposure groups for entire exposure period. Therefore, it can be concluded that antioxidants play a direct role in the adaptive response of E. fetida for survival in heavy metal contaminated soil. This adaptive antioxidant response can be used as an important biomarker to assess the toxicity of heavy metals in the soil ecosystems.

Pre-Service International Teaching Assistant’s (ITA’s) investments in their ITA Training Course
Authors: Anderson Roger 
Published: September 2022

Research has focused almost exclusively on ITA’s experiences as instructors, overlooking the ITA training class. This has led to the marginalization of Pre-Service ITA’s in the literature. The locus of potentially important learning, a descriptive, multiple case study examined the investment (Darvin & Norton, 2015) of 3 Pre-Service ITA’s in their ITA training class over one semester at a large U.S. university. Data included ITA’s weekly journals, individual interviews/ stimulated recalls, class assignments, and fieldnotes from classroom observations. Findings are presented as portraits of real, multifaceted ITA’s, then from cross-case analyses. Participants experienced the same course very differently, impacted most prominently by their ITA educators’ teaching approach, their exposure to teaching role models, and their home department structures. Recognizing the incredible diversity ITA’s represent, pedagogical implications suggest an “intense exposure experience” or teaching-training focused pedagogy be implemented -instead of test-centric pedagogies, situating ITA’s learning within un-simulated spaces with real undergraduates.
Research of the Stress-Strain State for Steel Support Structures of Nuclear Power Plant Components under Seismic Loads
Authors: Shugaylo O. , Bilyk S. 
Published: September 2022

Seismic resistance of equipment and piping of nuclear power plant units is determined, particularly, by seismic resistance of their steel support structures. A significant number of these structures are located in the reactor building of nuclear power plants and belong to seismic resistance categories I and II. Therefore, such support structures of nuclear power plant equipment and piping, in general, shall perform their functions under seismic hazards that correspond to the safe shutdown earthquake and design-basis earthquakes, respectively.
Steel support structures of serial equipment (piping valves, electric and pneumatic drives of piping and pump valves, expansion tanks, etc.) are often designed “on site” in the limited conditions of their actual location. Therefore, it is necessary to design steel support structures of a number of equipment taking into account the fact that it can be connected, in particular, to existing piping with their actual routing. In connection with the above, the research of operation for such support structures under seismic loads is relevant.
The article presents the research results for the spectrum of natural oscillation frequencies of the equipment support structure, and the stress-strain state of the considered structure under seismic loads is determined. At the same time, the parameters during normal operation and maximum design basis accident at the nuclear power plant power unit are considered. The calculated combination of loads, which simultaneously includes two episodic impacts (maximum design basis accident and an earthquake) is considered.

Authors: Szabó Péter J. 
Published: September 2022

Effect of plastic deformation on the lattice misorientation in lath martensite was investigated by Electron Backscatter Diffraction (EBSD). As-quenched rod-like specimens were plastically deformed until 9000 N, 14000 N, 19000 N and 21000 N of tensile loading. Grain average misorientation maps were collected by EBSD. It was shown that the average misorientation during plastic deformation increased from 0.887 to 1.156 degrees. Results showed that the density of geometrically necessary dislocations, which caused the lattice misorientation, slightly increased during plastic deformation of lath martensite.

Published: September 2022

BackgroundThe objective of this study was to build models that define variables contributing to pneumonia risk by applying supervised Machine Learning (ML) to medical and oral disease data to define key risk variables contributing to pneumonia emergence for any pneumonia/pneumonia subtypes.MethodsRetrospective medical and dental data were retrieved from the Marshfield Clinic Health System's data warehouse and the integrated electronic medical-dental health records (iEHR). Retrieved data were preprocessed prior to conducting analyses and included matching of cases to controls by (a) race/ethnicity and (b) 1:1 Case: Control ratio. Variables with &gt;30% missing data were excluded from analysis. Datasets were divided into four subsets: (1) All Pneumonia (all cases and controls); (2) community (CAP)/healthcare-associated (HCAP) pneumonias; (3) ventilator-associated (VAP)/hospital-acquired (HAP) pneumonias; and (4) aspiration pneumonia (AP). Performance of five algorithms was compared across the four subsets: Naïve Bayes, Logistic Regression, Support Vector Machine (SVM), Multi Layer Perceptron (MLP), and Random Forests. Feature (input variables) selection and 10-fold cross validation was performed on all the datasets. An evaluation set (10%) was extracted from the subsets for further validation. Model performance was evaluated in terms of total accuracy, sensitivity, specificity, F-measure, Mathews-correlation-coefficient, and area under receiver operating characteristic curve (AUC).ResultsIn total, 6,034 records (cases and controls) met eligibility for inclusion in the main dataset. After feature selection, the variables retained in the subsets were: All Pneumonia (n = 29 variables), CAP-HCAP (n = 26 variables), VAP-HAP (n = 40 variables), and AP (n = 37 variables). Variables retained (n = 22) were common across all four pneumonia subsets. Of these, the number of missing teeth, periodontal status, periodontal pocket depth more than 5 mm, and number of restored teeth contributed to all the subsets and were retained in the model. MLP outperformed other predictive models for All Pneumonia, CAP-HCAP, and AP subsets, while SVM outperformed other models in VAP-HAP subset.ConclusionThis study validates previously described associations between poor oral health and pneumonia. Benefits of an integrated medical-dental record and care delivery environment for modeling pneumonia risk are highlighted. Based on findings, risk score development could inform referrals and follow-up in integrated healthcare delivery environments and coordinated patient management.

Published: September 2022

ObjectiveThe purpose of this study was to examine whether the METS-IR index is associated with kidney stones in American adults.MethodParticipants from the National Health and Nutrition Examination Survey (NHANES) database from 2007-2018 were selected for logistic regression analysis, subgroup analyses, and the calculation of dose-response curves to assess the association between the METS-IR index and the incidence of kidney stones.ResultThis study enrolled 30,612 adults aged &gt;20 years, 2901 of whom self-reported having had kidney stones in the past. And, after controlling for potential confounders, each unit increase in the METS-IR index was linked with a 1.23 percent rise in kidney stone incidence (OR= 1.0123, 95% CI: 1.0092 - 1.0155), with stratified analysis indicating that this was true in all subgroups. Between all groups, an elevated METS-IR index was related to kidney stone formation, and the dose-response curve revealed a positive non-linear connection between METS-IR index and kidney stone risk, with a threshold effect analysis revealing an inflection point value of 50.8314.ConclusionHigher METS-IR index is associated with the occurrence of kidney stones,and while no causative association can be shown, this is cause for concern.
