DSP implementation of direct power control with constant switching frequency for three-phase PWM rectifiers

This paper proposes a novel and simple direct power control scheme for three-phase PWM rectifiers operated at constant switching frequency using space vector modulation (DPC-SVM). The active and reactive power is used as the pulse width modulated (PWM) control variables instead of the three-phase line currents usually used. Moreover, a line voltage sensors are replaced by virtual flux (VF) estimator. Theoretical principle of this method is discussed. The steady state and dynamic results of DPC-SVM scheme that illustrates the operation and performance of the proposed system are presented. It is shown that DPC-SVM exhibits several features as: simple algorithm, good dynamic response, constant switching frequency and particularly provide low THD sinusoidal line current when supply voltage is no ideal. Simulated and experimental results have proven excellent performances and verify the validity of the proposed system.
Multi-Omics Reveal Additive Cytotoxicity Effects of Aflatoxin B1 and Aflatoxin M1 toward Intestinal NCM460 Cells

Aflatoxin B1 (AFB1) is a common crop contaminant, while aflatoxin M1 (AFM1) is implicated in milk safety. Humans are likely to be simultaneously exposed to AFB1 and AFM1; however, studies on the combined interactive effects of AFB1 and AFM1 are lacking. To fill this knowledge gap, transcriptomic, proteomic, and microRNA (miRNA)-sequencing approaches were used to investigate the toxic mechanisms underpinning combined AFB1 and AFM1 actions in vitro. Exposure to AFB1 (1.25–20 μM) and AFM1 (5–20 μM) for 48 h significantly decreased cell viability in the intestinal cell line, NCM460. Multi-omics analyses demonstrated that additive toxic effects were induced by combined AFB1 (2.5 μM) and AFM1 (2.5 μM) in NCM460 cells and were associated with p53 signaling pathway, a common pathway enriched by differentially expressed mRNAs/proteins/miRNAs. Specifically, based on p53 signaling, cross-omics showed that AFB1 and AFM1 reduced NCM460 cell viability via the hsa-miR-628-3p- and hsa-miR-217-5p-mediated regulation of cell surface death receptor (FAS), and also the hsa-miR-11-y-mediated regulation of cyclin dependent kinase 2 (CDK2). We provide new insights on biomarkers which reflect the cytotoxic effects of combined AFB1 and AFM1 toxicity.
Secretory Profile of Adipose-Tissue-Derived Mesenchymal Stem Cells from Cats with Calicivirus-Positive Severe Chronic Gingivostomatitis

The feline calicivirus (FCV) causes infections in cats all over the world and seems to be related to a broad variety of clinical presentations, such as feline chronic gingivostomatitis (FCGS), a severe oral pathology in cats. Although its etiopathogeny is largely unknown, FCV infection is likely to be a main predisposing factor for developing this pathology. During recent years, new strategies for treating FCGS have been proposed, based on the use of mesenchymal stem cells (MSC) and their regenerative and immunomodulatory properties. The main mechanism of action of MSC seems to be paracrine, due to the secretion of many biomolecules with different biological functions (secretome). Currently, several pathologies in humans have been shown to be related to functional alterations of the patient’s MSCs. However, the possible roles that altered MSCs might have in different diseases, including virus-mediated diseases, remain unknown. We have recently demonstrated that the exosomes produced by the adipose-tissue-derived MSCs (fAd-MSCs) from cats suffering from FCV-positive severe and refractory FCGS showed altered protein contents. Based on these findings, the goal of this work was to analyze the proteomic profile of the secretome produced by feline adipose-tissue-derived MSCs (fAd-MSCs) from FCV-positive patients with FCGS, in order to identify differences between them and to increase our knowledge of the etiopathogenesis of this disease. We used high-resolution mass spectrometry and functional enrichment analysis with Gene Ontology to compare the secretomes produced by the fAd-MSCs of healthy and calicivirus-positive FCGS cats. We found that the fAd-MSCs from cats with FCGS had an increased expression of pro-inflammatory cytokines and an altered proteomic profile compared to the secretome produced by cells from healthy cats. These findings help us gain insight on the roles of MSCs and their possible relation to FCGS, and may be useful for selecting specific biomarkers and for identifying new therapeutic targets.

Against All Odds? Sami women's lower NEET experience in an Arctic Context: Education and Work Participation among Multicultural Young People in Northern-Norway, the Norwegian Arctic Adolescent Health Study (NAAHS)

The present paper explores Sami women’s lower NEET (Not engaged in Education, Employment or Training) experience in an ethnoreligious multicontext perspective. Data are derived from a cross-sectional cohort and registry follow-up study in Northern Norway, 2003–2012, and data from Statistics Norway are included for an up-to date data analysis (2021). This is a cross-sectional cohort and registry data study in Northern Norway, 2003-2012. The participants were adolescents and young people. Out of 5 877 10th graders 83% answered a questionnaire in a cross-sectional study, the Norwegian Arctic Adolescent Health Study (NAAHS), whereas consent-based follow-up consisted of 68% (3987 young people). There is an ethnic self-report of 9.2% with Sami ethnicity in the respondent/consent group, hence 10% in NAAHS. The outcome variables were educational aspirations, non-completion of upper secondary school, tertiary education, and NEET experience among female Sami young adults as explained by ethnoreligious affiliation. The explanatory variables are sociodemographic factors (gender, ethnicity, residency). Stratification of the participants are made by dividing girls and boys, Sami, and non-Sami, Laestadian and non-Laestadian and residency by counties in Arctic Norway (previously Finnmark, Troms and Nordland). The results show that Sami women stood positively out compared to majority women and all men through the footprint to work participation. Some of the conclusions from the study is that sociocultural and macroeconomic factors must be considered to create means for Sami women’s work participation.
Effect analysis of silencing grooves on pressure and vibration characteristics of seawater axial piston pump

Seawater axial piston pump is a critical power component in seawater fluid power system. As the properties of high bulk modulus and low viscosity of seawater, the pressure and vibration characteristics of the seawater axial piston pump will be getting poorer than the traditional oil pump. In this study, the pressure, flow, and vibration characteristics for a seawater axial piston pump are investigated. The three-dimensional computational fluid dynamics simulations for the port plate with non-grooved, U-shaped, and triangle-based pyramid silencing groove designs have been conducted over a range of operating conditions, which consider the fluid compressibility effect and cavitation damage. Measurements of pressure ripple and pump vibration are carried out at various loading conditions to verify the results of simulation. The experiment turned out that the well-designed port plate can mitigate both pressure ripples as well as vibrations of the pump. This research will lay the foundation for the further development of a low fluid noise seawater axial piston pump.
A real-time posture monitoring method for rail vehicle bodies based on machine vision

ABSTRACT Monitoring vehicle operation conditions has become significantly important in modern high-speed railway systems. However, the operational impact of monitoring the roll angle of vehicle bodies has principally been limited to tilting trains, while few studies have focused on monitoring the running posture of vehicle bodies during operation. We propose a real-time posture monitoring method to fulfil real-time monitoring requirements, by taking rail surfaces and centrelines as detection references. In realising the proposed method, we built a mathematical computational model based on space coordinate transformations to calculate attitude angles of vehicles in operation and vertical and lateral vibration displacements of single measuring points. Moreover, comparison and verification of reliability between system and field results were conducted. Results show that monitoring of the roll angles of car bodies obtained through the system exhibit variation trends similar to those converted from the dynamic deflection of bogie secondary air springs. The monitoring results of two identical conditions were basically the same, highlighting repeatability and good monitoring accuracy. Therefore, our monitoring results were reliable in reflecting posture changes in running railway vehicles.
Efficacy and Safety of Nutrient Supplements for Glycaemic Control and Insulin Resistance in Type 2 Diabetes: An Umbrella Review and Hierarchical Evidence Synthesis

Background: Nutrient supplements are widely used for type 2 diabetes (T2D), yet evidence-based guidance for clinicians is lacking. Methods: We searched the four electronic databases from November 2015–December 2021. The most recent, most comprehensive, high-ranked systematic reviews, meta-analyses, and/or umbrella reviews of randomised controlled trials in adults with T2D were included. Data were extracted on study characteristics, aggregate outcome measures per group (glycaemic control, measures of insulin sensitivity and secretion), adverse events, and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) assessments. Quality was assessed using A Measurement Tool to Assess Systematic Reviews Version 2.0 (AMSTAR 2). Results: Twelve meta-analyses and one umbrella review were included. There was very low certainty evidence that chromium, Vitamin C, and omega-3 polyunsaturated fatty acids (Ω-3 PUFAs) were superior to placebo for the primary outcome of glycated hemoglobin (HbA1c) (Mean Difference/MD −0.54, −0.54 and ES −0.27, respectively). Probiotics were superior to placebo for HbA1c (Weighted Mean Difference/WMD −0.43%). There was very low certainty evidence that Vitamin D was superior to placebo for lowering HbA1c in trials of <6 months (MD −0.17%). Magnesium, zinc, Vitamin C, probiotics, and polyphenols were superior to placebo for FBG. Vitamin D was superior to placebo for insulin resistance. Data on safety was limited. Conclusions: Future research should identify who may benefit from nutrient supplementation, safety, and optimal regimens and formulations.
Personality Traits, Motivation and Performance of Employees in a Pharmaceutical Company in the Philippines: Basis for Performance Improvement Plan

This descriptive correlational design study examined the relationship between employees' personality traits, motivation, and performance of employees in a pharmaceutical company in the Philippines. Corollary to this, it determined whether personality traits and motivation predict the work performance of medical sales representatives. A total of 125 medical sales representatives assigned at the NCR were selected for the study using stratified and universal sampling. Three instruments were used in this investigation: The Big Five Personality Test by Mcrae and Costa (2003) to identify the personality of the respondents; Work Motivation Questionnaire-A by Agarwal (2012), and the Performance Appraisal Evaluation by Getz Pharma (2018). Motivation and job performance were shown to be positively associated, as were personality traits and work performance, but motivation and personality were found to be unrelated. The strength of the relationship for the first two constructs, however, was weak. Further, results also suggested that material incentives and job situations were significant predictors of work performance. The majority of the findings are supported by the literature review, except for the link between personality traits and motivation in the context of sales, which needs further investigation. Finally, a general work performance improvement plan is recommended to further improve the performance of the medical sales representatives.
Active Vibration Control of Piezoelectric Sandwich Plates

This paper deals with the active vibration control of piezoelectric sandwich plate. The structure consists of a substrate plate layer sandwiched between two layers of piezoelectric sensor and actuator. Based on laminate theory and constitutive equation of piezoelectric material, the vibration active control dynamic equation of the sandwich structure is established by using hypothetical mode method and Hamilton principle. The Rayleigh-Ritz method is used to solve it. The form of hypothetical solution is used for approximate solution, which is simple and accurate. The method of this paper is verified by several examples. The parametric studies of the sandwich plate structures are carried out. The results show that applying different boundary conditions and piezoelectric patch positions to the structures have a great influence on the natural frequency. When the driving voltage increases, the deflection of the plate structures increase approximately linearly. The active vibration control studies are investigated as well. The results show that within a certain range, the larger the value of the speed feedback coefficient, the better the active control effect. The positions of the piezoelectric patches affect the effectiveness and cost of active control. When the piezoelectric plate is located at the fixed end, the effect and cost of active control are better than that at the midpoint and free end of the plate.
Hydraulic Characteristics and Sediment Yielding on Engineering Excavated Soil Slope under Simulated Rainfall

Engineering excavated soil slopes play an important role in artificial soil loss. In order to assess the impact of these engineering excavated soil slopes, hydraulic characteristics and sediment generation must be quantified. Field rainfall simulation experiments were conducted under five rainfall intensities (0.6, 1.1, 1.61, 2.12 and 2.54 mm/min) and three slope gradients (10°, 15°and 20°) on engineering excavated soil slopes. The precipitation of each rainfall was set to 50 mm, the duration of rainfall was 83, 45, 31, 24 and 20 min for simulated rainfall intensities of 0.6, 1.1, 1.61, 2.12 and 2.54 mm/min respectively. Plots used in this study were laid out to be 3 m in length and 1 m in width. Calibration of rainfall intensities was conducted before each experiment. Totally, 45 simulated rainfall events were performed. Three indices were used to research the soil erosion processes, including surface and subsurface runoff volume and the sediment yield. Results showed that: 1) both surface and subsurface runoff varied depending on slope gradient and rainfall intensity. Surface runoff and subsurface runoff were 33.6~42.7 mm and 0.15~ 1.24 mm, respectively. The process of surface runoff yield was the main hydrological process, accounting for 67.2~85.4% of the precipitation. Under conditions of low (0.6 mm/min) and high (2.12 and 2.54 mm/min) rainfall intensity, surface runoff increased with slope. 2)The averaged flow velocity, Reynold number, Froude number, Darcy-Weisbach friction coefficient, Manning roughness coefficients and stream power were 0.047~0.104 m/s, 48.985~392.918, 0.355~0.581, 1.317~5.171, 0.044~0.101 m-1/3·s, 0.029~0.457 kg·s-3, respectively. In addition, flow velocity and Reynold number had a greatly significant correlation with rainfall intensities, Manning roughness coefficients, Darcy-Weisbach friction coefficients and stream power a week correlation with rainfall intensity, Froude number had a week correlation with rainfall and slope. There was no obvious relationship between Darcy-Weisbach friction coefficient and the Reynolds number and there was a “increase resistance” phenomenon in engineering excavated soil slopes. 3) Interrill erosion was the main erosion form on engineering excavated soil slopes. Rainfall intensity, runoff rate and slope gradient are key factors to model sediment yield rate. Three commonly interrill erosion models were evaluated and compared, the fitness of model followed the pattern: model 1(NSE=0.977)>model 2(NSE=0.966)>model 3(NSE=0.924). A further comparison between the models showed that the convex curvilinear slope factor (model 1) was more precise than the power (model 3) and linear (model 3) slope factor in describing the effect of slope gradient for this data. Interrill erodibility adopted in the WEPP model was determined as 0.332×106 kg·s·m-4. The results provide valuable data for establishing water erosion prediction model of engineering excavated slope.
Effects of water quality on rural livelihoods: a case of Tamale Metropolis

Water quality issues are a challenge in both developed and developing countries, which affects the people who depend on it. This study aimed at examining the quality of water sources used by the residence of 18 rural areas in Tamale Metropolis and their effects on their livelihoods. This was done by collecting water samples from four different sources used by residents: hand-dug wells, boreholes, Ghana Water Company Limited (GWCL) household tap and dam for laboratory analysis for both dry and rainy seasons. Furthermore, selected respondents from 18 communities in rural Tamale in the Northern region of Ghana who depend on these water sources were interviewed to examine the effect of the water sources on their livelihoods. From the findings, almost all households have access to at least 2 of these water sources with 51 percent of households storing water due to the lack of year-round water. The water quality test also shows that apart from water provided by the GWCL which passed the standard for physico-chemical parameters; dam, well, and borehole test results for colour (10.9-105.0 Hz), turbidity (23.5-226.0 NTU) and iron (0.35-1.99 mg/l) fell beyond the recommended range set by World Health Organization. No water source could meet the bacteriological requirements with a total (7-1910 CFu) and faecal (7-1200 CFu) coliforms content increasing in the rainy season. Seventy-three (73) percent of households reported sharing water with animals and 41 percent perceived to drink from unclean sources. Additionally, 70 percent indicated an increase in diseases such as cholera and diarrhoea while 90 percent responded that the cost of getting quality or potable water and attending for healthcare affects their household income. The overall implication is that the effect of poor water quality on the livelihoods of rural residence in Tamale Metropolis is significant and requires urgent intervention.
ROLE OF FABP1 AS A DIAGNOSTIC BIOMARKER FOR NON-ALCOHOLIC FATTY PANCREATIC DISEASE

Background: Fatty pancreas or nonalcoholic fatty pancreatic disease (NAFPD) is an excessive fat infiltration of the pancreas due to obesity. The need of laboratory marker that can be used as simple non-invasive biomarker to aid in diagnosis is crucial to be adding to the investigations, especially when used the abdominal ultrasound. Fatty acid binding protein 1 (FABP1) is a tissue specific marker that can be used to diagnose NAFPD as per Nature. Objective: To determine the incidence of NAFPD among obese and non-obese Egyptian people with or without DM, evaluate for possible association with DM or obesity, correlate between pancreatic steatosis (NAFPD) and non-alcoholic liver disease, and evaluate the diagnostic role of FABP1 in Egyptian patient with or without DM in relation to obesity. Patients and methods: A prospective cohort study included 80 patients aged from 18-70 years,
