Inhibitors of Corrosion Induced by Sulfate-Reducing Bacteria

Currently, a lot of researcher’s attention is devoted to the problem of microbiologically influenced corrosion (MIC), since it causes huge damages to the economy, initiating the destruction of oil and gas pipelines and other underground constructions. To protect industrial materials from MIC effects an organic chemical inhibitors are massively used. However, the problem of their use is associated with toxicity, dangerous for the environment that caused the need for development the alternative methods of MIC repression. At the review, the data about different types of inhibitors-biocides usage has provided. The chemical inhibitors features are given and the mechanisms of their protective action are considered. The screening results and use of alternative and eco-friendly methods for managing the effect of corrosion caused by sulfate-reducing bacteria (SRB) are highlighted. Methods of joint application of chemical inhibitors and enhancers, such as chelators, biosurfactants, which contribute to reducing the concentration of chemical inhibitors, are discussed. The possibility of disruption of the quorum sensing interaction in the bacterial community to prevent the biofilm formation is considered. The information about the use of natural plant extracts, food waste, as well as by-products of agro-industrial production to combat MIC is provided. The development of biological corrosion control methods (to combat MIC) is of great importance for creating the best alternative and eco-friendly approaches to managing the effect of corrosion caused by SRB. The analysis of the literature data indicates the need to find the best alternatives and environmentally friendly solutions.
Association between Health-Related Physical Fitness and Risk of Dyslipidemia in University Staff: A Cross-Sectional Study and a ROC Curve Analysis

Background: This study aimed to assess the relationship between dyslipidemia (DL) risk and health-related physical fitness (HPF) and evaluated the prognostic value of HPF for risk of DL. Methods: A total of 776 university staff members were recruited, of which 407 were females, and 369 males. Blood samples and HPF tests were collected from all participants after 12 h fasting. Results: The prevalence of DL was 41.77% and 51.49% in female and male university staff members, respectively, and there was no significant difference between genders (χ2 = 2.687, p = 0.101). According to the logistic regression analysis, age, male sex, GLU, hypertension, BMI, BF, WHtR, and LAP were significant risk factors for DL (p < 0.05), VCI and, SAR were significant protective factors for DL (p < 0.05), and SMI, GS, and VG were not significantly associated with the risk of DL. The area under the receiver-operating characteristic (ROC) curve (AUC) analysis indicated that, LAP (AUC: 0.730, 95CI%: 0.697–0.762), WHtR (AUC: 0.626, 95CI%: 0.590–0.660), and BMI (AUC: 0.599, 95CI%: 0.563–0.634) are valid predictors of DL, and LAP and WHtR perform better than BMI (Z = 8.074, p < 0.001) in predicting DL in male and female university staff members. Conclusion: The risk of DL is significantly related to body composition, cardiorespiratory fitness, and flexibility. LAP and WHtR perform better than BMI in predicting risk of DL in male and female university staff members.
Understanding Adverse Childhood Experiences and Juvenile Court Outcomes: The Moderating Role of Race and Ethnicity

Youth involved in the juvenile justice system have enhanced traumatic exposure including abuse, neglect, and household dysfunction compared to their non-involved counterparts. While prior research has conceptualized the role of trauma in predicting juvenile recidivism, the interrelated role of adverse childhood experiences (ACEs) and race/ethnicity in informing juvenile court processing and outcomes is unaddressed. As such, we examine the moderating role of race/ethnicity with ACEs across court outcomes (e.g., dismissal, diversion, probation, residential placement) among juveniles after their first ever arrest (37.2% Black, 18.3% Hispanic). Higher ACEs were associated with (1) decreased adjudication likelihood, (2) case dismissal for Black and Hispanic youth, (3) deeper dispositions versus diversion for Hispanic youth, (4) residential placement versus diversion for White youth, and (5) residential placement versus probation, with no racial or ethnic differences. Policy implications and future research surrounding the treatment of justice-involved youth with childhood traumatic exposure across race/ethnicity are discussed.
Introduction of a Parameter Based Compressor Blade Model for Considering Measured Geometry Uncertainties in Numerical Simulation

This paper provides a method to transfer geometric uncertainties of compressor blades into the numerical simulation. Therefore a method to capture geometric variations of measured blades by typical profile parameters is introduced. An optical measurement technique using structured light is applied to scan compressor blades in order to receive a three–dimensional point cloud of the measured blade. The evaluation of these points is done on curves of constant spanwise coordinate between hub and casing. In this way, section outlines are extracted, which then are split into camber lines and chord lines. The derived thickness and camber distributions are used to specify typical profile parameters for each section. To consider the geometric uncertainties in numerical simulation, the design geometry is adapted through a special reconstruction algorithm. Therefore the differences between the measured airfoil and the design geometry are quantified by the profile parameters. Since only the difference is analyzed, few parameters are needed to model the measured geometry. The three-dimensional blade then is reconstructed through assignment of the parameters to the spanwise coordinate. To illustrate the developed method, the whole process chain is applied on a selected compressor blade.Copyright © 2009 by Rolls-Royce Deutschland Ltd. & Co. KG
Influence of dipeptidyl peptidase-4 inhibitors on glycemic variability in patients with type 2 diabetes: A meta-analysis of randomized controlled trials

Objective The influence of dipeptidyl peptidase-4 (DPP4) inhibitors on glycemic variability compared to other oral antidiabetic drugs (OADs), measured based on the mean amplitude of glycemic excursions (MAGE), has not been comprehensively analyzed. The aim of the study was to perform a meta-analysis to compare the effects of DPP4 inhibitors on MAGE with other OADs in type 2 diabetes mellitus (T2DM) patients without concurrent insulin treatments. Methods The Medline (PubMed), Embase (Ovid), and CENTER (Cochrane Library) databases were searched for relevant randomized controlled trials (RCTs). Study characteristics and outcome data were independently extracted by two authors. A random-effect model was used to combine the results. Results Fourteen studies with 855 patients were included. Compared to other OADs, DPP4 inhibitors significantly reduced MAGE (mean difference [MD]: -0.69 mmol/L, 95% confidence interval [CI]: -0.95 to -0.43, P<0.001) with mild heterogeneity (I2 = 28%). Predefined subgroup analyses suggested that DPP4 inhibitors were more effective in reducing MAGE compared to insulin secretagogues (MD: -0.92 mmol/L, P<0.001) and non-secretagogues (MD: -0.43 mmol/L, P=0.02), as well as compared to sulfonylureas (MD: -0.91 mmol/L, P<0.001) and sodium glucose cotransporter 2 inhibitors (MD: -0.67 mmol/L, P=0.03). Conclusions DPP4 inhibitors may significantly reduce glycemic variability compared to other oral anti-diabetic drugs, as evidenced by MAGE in T2DM patients with no concurrent insulin treatment.

Ergonomics of ergonomic chairs: a study of adjustability features

The ease of adjustability of ‘ergonomic chairs’ was investigated. Twenty-six chairs were classified with respect to control features. There were 24 different types of control arrangements. Twenty subjects participated in a series of three experiments. The first experiment investigated what types of control mechanisms could be identified by naive users who had received no training or instruction in the use of control devices. The chairs were classified into five broad categories, and one chair from each category was tested. Two control design features, control discernibility and control feedback, significantly improved users' understanding of the adjustability controls. In the second experiment controls on 20 chairs were evaluated. Subjects were first trained in the operation of the controls for each chair; and then they performed a chair adjustability task. Six control evaluation criteria were used: reachability, force, ease of operation, preference, time to adjust, and number of control activations. Cont.
An Analysis of Lexical Collocation Errors in Students’ Writing

Mastering lexical collocation uses in learning English as a foreign language is absolutely essential to develop students’ communicative skills and linguistic abilities. Most students, however, have problems with putting words together in a characteristic of “natural” English native speaker-like manner during writing. Students tend to use strange lexical collocation expressions therefore students’ language production does not sound natural and carries imprecise meaning. With regard to this underlying issue, the main emphasis of the current study was lying on the investigation of the types and the causes of lexical collocation error committed by EFL students in their argumentative writing. Through a qualitative research approach applying a descriptive-analytic method, sixteen university students were chosen purposively. The data were collected from two principal sources i.e., students’ writing samples and semi-structured interviews. In terms of data analysis technique, this study employed an error analysis technique developed by Ellis (1994) to analyze the obtained lexical collocation errors and applied a content analysis technique provided by Kumar (2011) to analyze the interview results. The study revealed 54 erroneousness of lexical collocation production consisting of verb + noun/pronoun (PP), adjective + noun, adverb + adjective, noun + noun, and verb + adverb combination. These errors were caused by a lack of collocation competence, native language influence, the use of synonym, overgeneralization, and approximation.
Raman spectroscopic study of pressure–induced phase transitions in tridymite modifications

Pressure–induced phase transitions of tridymite modifications (MC, MX–1, and PO–10) were investigated by in–situ Raman spectroscopy. Starting from MC, a transition to PO–10 was observed at 0.4 GPa. At about 1.6 GPa, new Raman peaks appeared and were observed up to 8.7 GPa. This revealed a new phase, and it reverted to PO–10 at around 0.4 GPa during decompression. Contrary to previous study, PO–10 was recovered to ambient pressure. MX–1 also transformed to PO–10, and PO–10 was recovered. Starting from PO–10, the transition to the new phase was also observed but was gradual and the phase reverted to PO–10 during decompression. Present study revealed a new route to form PO–10 from MC and suggests rare PO–10 found in meteorites could be formed through this route.
An Adaptive Institution? The German Vocational Education System and Pressures for Change

ABSTRACT This article outlines the main elements of the German system of vocational training and looks at recent pressure for change in the system. It identifies two central elements in the system, the notion of the occupation and the dual structure of training delivery. These characteristics are embedded in an array of institutional arrangements which include co-determination within companies, industry-level collective bargaining, national legislation defining occupational categories, and state provision for apprenticeship schools. Several criticisms of the German vocational training system have emerged in recent years, reflecting changes in the German economy and society and the influence of external economic pressures for change. A review of some of the criticisms of the vocational training system and of legislative responses suggests that the system has managed most of these pressures by adapting its institutional arrangements rather than abandoning them.
On the dynamic response of regular structures exhibiting tilt

The mechanical characteristics of earthquake-resistant structures and the ground motion properties that have an important influence on the seismic performance of structures with asymmetric load–deformation behaviour, are identified from the results obtained from a parametric study of the dynamic response of single-degree-of-freedom systems. The dynamic response of tilted single and multi-degree-of-freedom systems, designed according to Mexican requirements for the design of asymmetric structures is studied. After a general understanding of this phenomenon is offered, shortcomings in current design requirements for tilted structures are discussed. Research needs to establish a rational design approach of this type of structures are identified. Copyright © 2000 John Wiley & Sons, Ltd.
Combined Effects of Citrulline Plus Nitrate-Rich Beetroot Extract Co-Supplementation on Maximal and Endurance-Strength and Aerobic Power in Trained Male Triathletes: A Randomized Double-Blind, Placebo-Controlled Trial

Citrulline (CIT) and nitrate-rich beetroot extract (BR) are ergogenic aids and nitric oxide (NO) precursors. In addition, both supplements seem to have other actions at the level of muscle metabolism that can benefit strength and aerobic power performance. Both supplements have been studied in numerous investigations in isolation. However, scientific evidence combining both supplements is scarce, and to the best of the authors’ knowledge, there is no current study of endurance athletes. Therefore, the main purpose of this study was to determine the effect of 9 weeks of CIT plus BR supplementation on maximal and endurance-strength performance and aerobic power in male triathletes. This study was a randomized double-blind, placebo-controlled trial where participants (n = 32) were randomized into four different groups: placebo group (PLG; n = 8), CIT plus BR group (CIT- BRG; 3 g/kg/day of CIT plus 3 mg/kg/day of nitrates (NO3−); n = 8), CIT group (CITG; 3 g/kg/day; n = 8) and BR group (BRG; 3 mg/kg/day of NO3−; n = 8). Before (T1) and after 9 weeks (T2), four physical condition tests were carried out in order to assess sport performance: the horizontal jump test (HJUMP), handgrip dynamometer test, 1-min abdominal tests (1-MAT) and finally, the Cooper test. Although, no significant interactions (time × supplementation groups) were found for the strength tests (p > 0.05), the CIT- BRG supplementation presented a trend on HJUMP and 1-MAT tests confirmed by significant increase between two study moments in CIT-BRG. Likewise, CIT-BRG presented significant interactions in the aerobic power test confirmed by this group’s improve estimated VO2max during the study with respect to the other study groups (p = 0.002; η2p = 0.418). In summary, supplementing with 3 g/day of CIT and 2.1 g/day of BR (300 mg/day of NO3−) for 9 weeks could increase maximal and endurance strength. Furthermore, when compared to CIT or BR supplementation alone, this combination improved performance in tests related to aerobic power.
Recommendations from LGBTQ+ adults for increased inclusion within physical activity: a qualitative content analysis.

For decades, physical activity contexts have been inherently exclusionary toward LGBTQ+ participation through their perpetuation of practices and systems that support sexuality- and gender-based discrimination. Progress toward LGBTQ+ inclusivity within physical activity has been severely limited by a lack of actionable and practical suggestions. The purpose of this study was to garner an extensive account of suggestions for inclusivity from LGBTQ+ adults. Using an online cross-sectional survey, LGBTQ+ adults (N = 766) were asked the following open-ended question, "in what ways do you think physical activity could be altered to be more inclusive of LGBTQ+ participation? " The resulting texts were coded using inductive qualitative content analysis. All coding was subject to critical peer review. Participants' suggestions have been organized and presented under two overarching points of improvement: (a) creation of safe(r) spaces and (b) challenging the gender binary. Participants (n = 558; 72.8%) outlined several components integral to the creation and maintenance of safe(r) spaces such as: (i) LGBTQ+ memberships, (ii) inclusivity training for fitness facility staff, (iii) informative advertisement of LGBTQ+ inclusion, (iv) antidiscrimination policies, and (v) diverse representation. Suggestions for challenging the gender binary (n = 483; 63.1%) called for the creation of single stalls or gender-neutral locker rooms, as well as for the questioning of gender-based stereotypes and binary divisions of gender within physical activity (e.g., using skill level and experience to divide sports teams as opposed to gender). The findings of this study represent a multitude of practical suggestions for LGBTQ+ inclusivity that can be applied to a myriad of physical activity contexts.
Companies’ Stock Market Performance in the Time of COVID-19: Alternative Energy vs. Main Stock Market Sectors

The paper aims to detect the differences in stock market performance between companies from the alternative energy sector and main stock market sectors in the first and second years of the COVID-19 pandemic. We used Global Industry Classification Standard to analyse eleven main stock market sectors and the alternative energy sector. Based on the one-factor variance analysis—ANOVA, we reveal the statistically significant differences between the analysed stock market sectors in both 2020 and 2021. The analysis implied that the performance of stock market companies during COVID-19 is sector-specific. Tukey’s Honestly Significant Difference (HSD) test for pairwise comparison indicates that the alternative energy sector shows the most differentiation. Its average rate of return in 2020 is the highest and is significantly different for all eleven stock market sectors, while the top constituents from the conventional energy and financial sectors suffered the most. In 2021, a reverse trend in the stock prices can be observed. Companies from the conventional energy and financial sectors achieved the highest positive average weekly rates of return among all of the analysed stock market sectors, while the alternative energy sector performed significantly worse than the other sectors did. Nevertheless, throughout the entire analyses period of 2020–2021, the companies from the alternative energy sector turned out to be the biggest stock market beneficiaries. This study might imply that the COVID-19 pandemic has not hampered but has instead accelerated growing concerns about the environment and climate change.
A Descriptive Study on the Clinical Correlates of Conversion Disorder

Aim: Conversion disorder is defined by the presence of deficits affecting the voluntary motor or sensory functions lacking any known neurological cause. The aim of the study is to describe the sociodemographic profile and clinical characteristics including the frequency distribution of various types of presentations of patients with conversion disorders in a tertiary care psychiatric facility and to assess the presence of depression and anxiety and its level of severity in those patients. Methods: After obtaining informed consent, 50 consecutive patients who had met with the ICD-10 diagnosis criteria for conversion disorder and those who meet the inclusion/exclusion criteria, were enrolled for the study. They were interviewed using a semi-structured Performa and were administered Hospital Anxiety and Depression scale (HADS) and the results were analysed using SPSS software and interpreted. Results: Majority of the study patients were young adolescents (48%), females (76%), rural residents (60%), mostly unmarried (46%). Dissociative motor disorders (30%) were the most common presentation followed by mixed dissociative disorder (26%) and Dissociative convulsions (22%). HAD scale revealed that, both depression and anxiety scores were significantly high in major number of patients. Conclusion: The most common presenting symptom was that of dissociative motor type followed by dissociative convulsions with considerably high rates of depression (48%) and anxiety (54%). This made us to conclude that conversion as a phenomenon emerges to uphold its significance as a non-verbal communication process of the subconscious Mind. Keywords: Conversion, Dissociation, Hysteria, Dissociative Motor Disorder, Dissociative Convulsions, Laterality, Depression, Anxiety.
Immunological tolerance in the evolution of male pregnancy

The unique male pregnancy in pipefishes and seahorses ranges from basic attachment (pouch‐less species: Nerophinae) of maternal eggs to specialized internal gestation in pouched species (e.g. Syngnathus and Hippocampus) with many transitions in between. Due to this diversity, male pregnancy offers a unique platform for assessing physiological and molecular adaptations in pregnancy evolution. These insights will contribute to answering long‐standing questions of why and how pregnancy evolved convergently in so many vertebrate systems. To understand the molecular congruencies and disparities in male pregnancy evolution, we compared transcriptome‐wide differentially expressed genes in four syngnathid species, at four pregnancy stages (nonpregnant, early, late and parturition). Across all species and pregnancy forms, metabolic processes and immune dynamics defined pregnancy stages, especially pouched species shared expression features akin to female pregnancy. The observed downregulation of adaptive immune genes in early‐stage pregnancy and its reversed upregulation during late/parturition in pouched species, most notably in Hippocampus, combined with directionless expression in the pouch‐less species, suggests immune modulation to be restricted to pouched species that evolved placenta‐like systems. We propose that increased foeto‐paternal intimacy in pouched syngnathids commands immune suppression processes in early gestation, and that the elevated immune response during parturition coincides with pouch opening and reduced progeny reliance. Immune response regulation in pouched species supports the recently described functional MHC II pathway loss as critical in male pregnancy evolution. The independent co‐option of similar genes and pathways both in male and female pregnancy highlights immune modulation as crucial for the evolutionary establishment of pregnancy.
A new model for squeeze-film damping of electrically actuated microbeams under the effect of a static deflection

This paper presents a new approach to the modeling of squeeze-film damping for electrically actuated microbeams under the effect of a static deflection. The approach utilizes the compressible Reynolds equation coupled with the equation governing the beam deflection. Two squeeze-film damping models for a cantilever microbeam and a fixed–fixed microbeam are derived, respectively. The pressure in the air gap is represented by the product of an assumed parabolic function along the beamwidth and a cosine series along the beam length. Compared with the previous models, the present models account for the static deflection due to the electric load; thus the present models can be used for general purpose design, analysis and optimization of microbeam-based devices. The accuracy of the present models is verified by comparing their results with the experimental results available in the literature.
