The Impact of Job Enrichment on Job Satisfaction of Local Government Workers in Temeke Municipal Council of Tanzania

This study examines the impact of job enrichment on employee job satisfaction of local government workers in Tanzania. Specifically, the study examines how job characteristics, job meaningfulness, job responsibilities, and knowledge about job results impact employee job satisfaction. The target population of the study is 4000 employees of Temeke Municipal Council in Tanzania from which a sample of 396 respondents were drawn using a stratified simple random sampling technique. Temeke Municipal Council was selected since it is one of the biggest municipalities where the workers are highly dissatisfied due to the big workload and the pressure from the central bureaucracy, but it is not clear to what extent job enrichment is affecting job satisfaction. The data were collected through a self-administered questionnaire with closed-ended questions and analyzed quantitatively using descriptive statistics and regression analysis with the aid of STATA software. The findings show that job enrichment impacts positively on employees' job satisfaction because all the variables of job enrichments show a strong positive and statistically significant relationship with job satisfaction. This study recommends that job satisfaction among employees of the organizations could be increased through enriching their jobs focusing on job characteristics, job meaningfulness, job responsibilities, and knowledge about job results.

One-Dimensional Modeling and Experimental Analysis of Nail Penetration Thermal Runaway for Large Capacity Li-Ion Power Battery

This paper takes a certain type of large-capacity pure electric vehicle NCM li-ion power battery as the object, and analyzes and studies the process of nail penetration thermal runaway(TR). With the aid of AMEsim one-dimensional simulation software, considering the structure composition of the cell, the heat generation mechanism of each side reaction and the three heat transfer modes of thermal radiation, heat conduction and convective heat transfer between the cells, box and the environment, the thermoelectric characteristics of the battery module (six cells) are modeled. The TR behavior of the battery module during nail penetration is simulated and analyzed, and the experiment of the battery module is carried out according to Chinese new regulation GB 38031−2020. The experimental results verify the accuracy of the established model and the reliability of the simulation results, and provide technical reference for the design and development of battery thermal management such as the prediction of TR temperature and the safety of preventing TRP of battery pack.

Effect of Heat Treatment on Tensile Properties and Microstructure of Co-Free, Low Ni-10 Mo-1.2 Ti Maraging Steel.

Production of high-quality maraging steel is dependent not only on the production technology but also on the alloying design and heat treatment. In this work, cobalt-free, low nickel, molybdenum-containing maraging steel was produced by melting the raw materials in a vacuum induction melting furnace and then refining with a shielding gas electroslag remelting unit. The critical transformation temperatures of the investigated steel samples were determined experimentally by differential scanning calorimetry (DSC) analysis and theoretically aiding Thermo-Calc software. Types and chemical composition plus volume fraction and starting precipitation temperature of suggested constituents calculated with the aid of Thermo-Calc software. The microstructures of forged steel specimens that were heat-treated under several conditions were evaluated by X-ray diffraction (XRD), optical microscopy (OP), scanning electron microscopy (SEM), and electron backscattering (EBSD), in addition to transmission electron microscopy (TEM). The mechanical properties of the investigated steel specimens were evaluated by measuring the tensile strength properties and micro-hardness, furthermore, estimating their fracture surface using scanning electron microscopy at lower magnification. The metallographic results show that the microstructure of steel in aged conditions includes high-alloyed martensite and nickel-rich phase, in addition to the low-alloyed-retained-austenite, intermetallic compounds, and lavas-phase (MoCr). Furthermore, TEM and EBSD studies emphasized that the produced steel has high dislocation density with nano-sized precipitate with an average size of ~19 ± 1 nm. Moreover, the metallographic results show that the mentioned microstructure enhances the tensile properties by precipitation strengthening and the TRIP phenomenon. The tensile strength results show that the n-value of investigated steel passes two stages and is comparable with the n-value of TRIP-steel. Steel characterized by 2100 MPa ultimate tensile strength and uniform elongation of more than 7% can be produced by the investigated production routine and optimum heat treatment conditions.

Study on Stress Field Distribution during the Construction of a Group of Tunnels Using the Pile–Beam–Arch Method

To study stress field distributions during the construction of a group of tunnels using the pile–beam–arch method, the excavation for an underground station of Beijing subway line 7 was taken as an engineering problem, and a numerical structural model of a tunnel group was built with the aid of software. In this model, four stress-monitoring planes were set up to extract the data obtained from monitoring stress. The construction of the pilot tunnels was simulated according to six established construction schemes, and images were generated for the stress field distribution on each monitoring plane using different schemes. Finally, a verification of physical model tests was carried out. The results show that the effect of excavation on vertical stress in pilot tunnels has a range that is essentially equal to twice the width of the station. After the excavation of pilot tunnels, peaks appeared both at the tops of the pilot tunnels and between the bottoms of the tunnels; moreover, valleys appeared both at the bottoms of the pilot tunnels and between the tops of the tunnels. Pilot tunnels located at the top of the group were less affected during excavation than the tunnels located at the bottom of the group both in stress concentration factor and in the point of extreme stress. Finally, the model verified the numerical simulation results of the stress variation law.

Factors Driving Pregnant Women’s Participation in Non-therapeautic Clinical Research in Tanzania: Qualitative Findings from Mwananyamala Regional Hospital, Dar-Es-Salaam Region

Background: Pregnant women’s participation in non-therapeutic clinical trials has gained global attention. However, the imposition of unnecessary harm to the fetuses because of their participation is questionable. This is proved by the historical tragedies that resulted from the use of diethylstilbestrol and thalidomide, which caused cancer among daughters of the treated women. Methods: The study was an exploratory qualitative facility-based conducted at Mwananyamala Regional Hospital in Kinondoni District, Dar-es-Salaam Region, Tanzania, among pregnant women who were enrolled in a clinical trial: “Adverse birth outcomes among mothers who received intermittent preventive treatment with Sulphadoxine- Pyrimethamine in the low malaria transmission region”. Data were collected through in-depth interviews and analyzed by thematic analysis with the aid of NVivo computer software. Findings: Several push and pull factors such as saving of the life of the fetus and the mother; delivery complications; the desire to contribute to maternal-fetal science; societal benefits; incentives; advice from medical professionals; free or voluntary participation, and therapeutic misconception influenced pregnant women to voluntarily participate in non-therapeutic clinical researches. Conclusion: The study findings show that saving of the life of the fetus and the mother, delivery complications, desire to contribute to maternal-fetal science, advice from medical professionals, and incentives were core factors for pregnant women’s participation in non-therapeutic clinical researches in Tanzania. Fetal harms and therapeutic misconceptions decelerate pregnant women’s rate to participate in non-therapeutic clinical researches hence bioethical education is highly needed in this aspect.

A proposed formation mechanism of the Type-A radiocaesium-bearing microparticles released from Units 2/3 during the Fukushima Daiichi Nuclear Power Plant accident

A large amount of radiocaesium-bearing microparticles (CsMPs) were released into surrounding environment during the Fukushima Daiichi Nuclear Power Plant accident. To clarify the formation mechanism of the Type-A CsMPs, which were released from Units 2/3 and have spherical or ellipsoidal morphologies, oxidation behavior of 304 stainless steel containing 1 wt.% Si at 1200 ºC in steam atmosphere was investigated in this work. Both Fe2SiO4 and Ni-Fe-Cr phases were formed and distributed in the porous oxide scale. With the progress of oxidation, Fe2SiO4 and Ni-Fe-Cr phases were oxidized, causing severe spallation of the oxide scale somewhere between 90 min and 120 min. Trace amounts of Al and Ti were detected in the silica microparticles transformed from Fe2SiO4 oxidation. Furthermore, thermodynamic calculations were performed with the aid of FactSage software, revealing that: (1) when severe spallation of the oxide scale occurs, high levels of Fe oxides can stably exist in silica-based microparticles distributed in the oxide scale; (2) the Type-A CsMPs may be formed in reducing atmospheres. Based on the experimental and thermodynamic results, a completely new formation mechanism of the Type-A CsMPs is proposed. Silicate matrix is inherited from partially oxidized FeO-bearing silica-based microparticles, which are released from the oxide scale due to spallation. Moreover, diffusion of volatile constituents into FeO-bearing silica-based microparticles occurs in the reactor pressure vessel (RPV), not out of the RPV. This new formation mechanism can well explain many characteristics of the Type-A CsMPs.

Willingness of French General Practitioners to Prescribe mHealth Apps and Devices: Quantitative Study.

BackgroundThe field of mobile health (mHealth) is constantly expanding. Integrating mHealth apps and devices in clinical practice is a major and complex challenge. General practitioners (GPs) are an essential link in a patient’s care pathway. As they are patients’ preferred health care intermediaries, GPs play an important role in supporting patients’ transition to mHealth.ObjectiveThis study aims to identify the factors associated with the willingness of French GPs to prescribe mHealth apps and devices to their patients.MethodsThis study was part of the ApiAppS project whose overall objective was to help remove barriers GPs face when prescribing mHealth apps and devices by developing a custom-built platform to aid them. The study included GPs recruited from the general practice department of several medical faculties in France (Lyon, Nice, and Rouen) and mailing lists of academic GPs, health care professional associations, and social and professional networks. Participants were asked to complete a web-based questionnaire that collected data on various sociodemographic variables, indicators of their involvement in continued education programs and the amount of time they dedicated to promoting healthy behaviors during patient consultations, and indicators characterizing their patient population. Data on their perceptions of mHealth apps and devices were also collected. Finally, the questionnaire included items to measure GPs’ acceptability of prescribing mHealth apps and devices for several health-related dimensions.ResultsOf the 174 GPs, 129 (74.1%) declared their willingness to prescribe mHealth apps and devices to their patients. In multivariate analysis, involvement in continued education programs (odds ratio [OR] 6.17, 95% CI 1.52-28.72), a better patient base command of the French language (OR 1.45, 95% CI 1.13-1.88), GP-perceived benefits of mHealth apps and devices for both patients and their medical practice and GP-perceived drivers for mHealth apps and device implementation in their medical practice (OR 1.04, 95% CI 1.01-1.07), and validation of mHealth apps and devices through randomized clinical trials (OR 1.02, 95% CI 1.00-1.04) were all associated with GPs’ willingness to prescribe mHealth apps and devices. In contrast, older GPs (OR 0.95, 95% CI 0.91-0.98), female GPs (OR 0.26, 95% CI 0.09-0.69), and those who perceived risks for the patient or their medical practice (OR 0.96, 95% CI 0.94-0.99) were less inclined to prescribe mHealth apps and devices.ConclusionsmHealth apps and devices were generally seen by GPs as useful in general medicine and were, for the most part, favorable to prescribing them. Their full integration in general medicine will be conditioned by the need for conclusive certification, transparency (reliable and precise data concerning mHealth app and device methods of construction and clinical validation), software aids to assist GPs prescribe them, and dedicated training programs.

And finally, it revealed a negative but significant effect of financing activities on the liquidity of listed pharmaceutical companies in Nigeria. Therefore, it was recommended that listed pharmaceutical companies in Nigeria should be encouraged to build a reasonable cash flow control strategy that will bring efficiency to the firm, thereby enhancing the firm financial performance. Also, pharmaceutical companies should re-evaluate their cash flow management strategies in order to enable them to generate enough cash sufficient to meet their investing activities.

A Novel Truncated DNAzyme Modified Paper Analytical Device for Point-of-Care Test of Copper Ions in Natural Waters

On-site determination of trace copper ions in natural waters is of great significance to environmental monitoring, and how to develop accurate and specific point-of-care test methods is one critical issue. In the study, a paper-based analytical device (PAD) being modified with a new truncated DNAzyme (CLICK-T, which was derived from a reported DNAzyme-CLICK-17) was developed for Cu ions detection. The detection mechanism was based on Cu(II)-catalyzed azide-alkyne cycloaddition (Cu(II)AAC) reaction. It can directly conduct on-site analysis of Cu(II) ions based on fluorescent signals detected using a mobile phone. In the assay, the CLICK-T was firstly modified on the PADs. Then, water samples containing Cu ions mixed with 3-azido-7-hydroxycoumarin and 3-butyn-1-ol were instantly dripped on PADs and incubated for 20 min. Finally, the PADs were excited at 365 nm and emitted fluorescence which could be analyzed on site using smart phones. The Cu(II) concentration could be quantified through RGB analysis with the aid of iPhone APP software. The limit of detection is 0.1 µM by the naked eye due to the fact that CLICK-T exhibited a good catalytic effect on Cu(II)AAC. The Cu(II) concentration could also be directly detected without using reductant, such as ascorbic acid, which is prone to be oxidized in air. This simplifies the PDA detection process improves its efficiency. The PAD is convenient for the on-site analysis of Cu ions in natural waters.

A comparative assessment of GSM and UMTS Networks

It is common knowledge that the transition of mobile networks from one generation to another is basically for the improvement in the network’s Quality of Service (QoS). Bearing this in mind, we will assumme that the Universal Mobile Telecommunication System (UMTS) will outperform the Global System for Mobile Communication (GSM), hence, the motivation to conduct this study in Calabar, Nigeria, for four mobile networks; MTN, Airtel, Globacom and 9mobile. With the aid of a TEMS investigation software installed in a laptop, a measurement campaign was carried out and log files collected, with focus on Call Setup Success Rate (CSSR), Dropped Call Rate (DCR), Handover Success Rate (HOSR), Call Setup Time (CST), network coverage and network quality. The collected data was analyzed with the aid of a TEMS discovery software. The analyzed data for each Key Performance Indicator (KPI) was compared with the minimum benchmark of the telecommunications regulatory body, the Nigerian Communication Commission (NCC). Result reveal that there was no outright improvement in the QoS and there was fluctuation in the QoS provided by the network operators. We therefore conclude that the network operators, either did not make accurate planning before installing their base stations or do not optimize their networks frequently and this led to poor QoS in most cases.

Identification of Arboreal Vegetation and Potential Areas in the Commercial Center of Capitão Poço, Brazil

Green spaces are urban spaces that bring man and nature closer together, positively influencing the quality of life of the population. The planning of green spaces is essential in urban areas and Geographic Information Systems (GIS’s) are tools capable of assisting in the identification, management and monitoring of these spaces. The objective of the work was to map the urban vegetation and carry out a survey of potential areas for parks and green areas in the commercial center from the municipality of Capitão Poço - PA. The study was carried out in the commercial center from Capitão Poço, PA - Brazil by obtaining images from the Google Earth software and photointerpreted with the aid of the QGIS software. Finally, the current and potential tree green areas were identified in the georeferenced images. The survey of green areas in the commercial center identified that only 4.74% of the total area contains tree vegetation, in addition to 53% of this vegetation being found around the mother church and the municipal square of Alvorada. For potential green areas, it was found that the commercial center has 5,873.5% more potential areas in relation to current tree vegetation. In this sense, it is observed that the commercial center from the municipality of Capitão Poço contains a low proportion of areas with arboreal vegetation and a high potential for the implantation of parks, forests and other types of green areas.

Pharmacological Mechanisms of Tinglizi against Chronic Heart Failure Determined by Network Pharmacology and Molecular Docking.

Objective Tinglizi has been extensively used to treat chronic heart failure (CHF) in modern times, but the material basis and pharmacological mechanisms are still unclear. To explore the material basis and corresponding potential targets and to elucidate the mechanism of Tinglizi, network pharmacology and molecular docking methods were utilized. Methods The main chemical compounds and potential targets of Tinglizi were collected from the pharmacological database analysis platform (TCMSP). The corresponding genes of related action targets were queried through gene cards and UniProt database. The corresponding genes of CHF-related targets were searched through Disgenet database, and the intersection targets were obtained by drawing Venn map with the target genes related to pharmacodynamic components. Then, drug targets and disease targets were intersected and put into STRING database to establish a protein interaction network. The “active ingredient-CHF target” network was constructed with Cytoscape 3.8.2. Finally, Gene Ontology (GO) Enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment of intersection targets were analyzed using metascape. With the aid of SYBYL software, the key active ingredients and core targets were docked at molecular level, and the results were visualized by PyMOL software. Molecular docking was carried out to investigate interactions between active compounds and potential targets. Results A total of 12 active components in Tinglizi were chosen from the TCMSP database, and 193 corresponding targets were predicted. Twenty-nine potential targets of Tinglizi on CHF were obtained, of which nine were the core targets of this study. Twenty GO items were obtained by GO function enrichment analysis (P < 0.05), and 10 signal pathways were screened by KEGG pathway enrichment analysis (P < 0.05), which is closely related to the treatment of CHF by Tinglizi. The constructed drug compound composition action target disease network shows that quercetin, kaempferol, and other active compounds play a key role in the whole network. The results of molecular docking showed that all the key active ingredients, such as quercetin and isorhamnetin, were able to successfully dock with ADRB2 and HMOX1 with a total score above 5.0, suggesting that these key components have a strong binding force with the targets. Conclusion Through network pharmacology and molecular docking technology, we found that the main components of Tinglizi in the treatment of CHF are quercetin, kaempferol, β-sitosterol, isorhamnetin, and so on. The action targets are beta 2-adrenergic receptor (ADRB2), heme oxygenase 1 (HMOX1), and so on. The main pathways are advanced glycation end products/receptor for advanced glycation end products (AGE-RAGE) signaling pathway in diabetic complications, hypoxia-inducible factor (HIF-1) signaling pathway, estrogen signaling pathway, and so on. They play an integrated role in the treatment of CHF.

Thermophoresis and Brownian motion effects on Williamson nanofluid flow past a stretching surface with thermal radiation and chemical reaction

AbstractThe heat transfer mechanism of nanofluids has numerous industrial applications owing to the non‐Newtonian behavior and has been exercised as a thermophysical phenomena in presence of thermal radiation. The present paper deals with the thermal transfer characteristics of time‐independent magnetohydrodynamics Williamson fluid past a stretching surface in presence of the reaction of chemical equilibrium is dealt. The flow constitutive nonlinear partial differential coupled equations are transmitted into ordinary differential equalities by employing relevant similarity transmutations. These deduced equations are determined by using the Runge–Kutta numerical technique with a shooting approach with the aid of MATLAB software. Influences of distinct pertinent flow parameters like an inclined uniform magnetic field, Soret number, heat generation/absorption, and Schmidt number constrained to convective boundary condition is displayed through graphs with relevant physical interpretations. Computed numerical values for the friction factor coefficient, local Nusselt parameter, and Sherwood number are tabulated.

Smartphone-based fluorescence detection of bilirubin using yellow emissive carbon dots.

Development of highly sensitive and selective fluorescent probes for biomolecule detection has significant implications in clinical diagnosis and bioanalysis. In this study, yellow emissive carbon dots (Y-CDs, λex 430 nm, λem 550 nm) are synthesized utilizing a one-pot solvothermal approach with o-phenylenediamine (oPDA) as a precursor. The fluorescence of Y-CDs was quenched with the addition of bilirubin due to the inner filter effect mechanism. The fluorescence intensity of Y-CDs decreases as bilirubin concentration increases and can be completely quenched with approximately 90 μM bilirubin. Over other coexisting interferents (26 interferents), the Y-CD probe exhibited great selectivity for bilirubin. More crucially, a smartphone can capture the visible color intensity change of the Y-CD probe under a 365 nm UV lamp and later with the aid of computer software, RGB (red/green/blue) analysis was performed for the quantification of colors. This provides computer vision-based detection and sensitive bilirubin assay with a linear range of 4.0-225 μM and a limit of detection of 1.37 μM. Furthermore, the proposed fluorescent probe was applied in real samples (newborn serum, serum and urine of adults with hyperbilirubinemia) with satisfactory recoveries (96-102%). Based on the validation findings, solution and computer vision-based methods have the potential to be used as fast detection methods for bilirubin in biological samples at the bedside. For the first time, a fluorescent probe based on yellow emissive CDs and RGB analysis for bilirubin recognition has been reported.

Radial force cancellation of bearingless brushless direct current motor using integrated winding configuration

A bearingless brushless direct current (BLDC) motor incorporates the function of magnetic bearings into a BLDC motor, making it a new type of high-performance motor. In this paper, the main motor windings are used to generate the radial force cancellation by injecting the required dc current, “integrated winding configuration”. The bearingless BLDC motor, direct current (DC) cancellation system model is established with the aid of (ANSYS/MAXWELL) software. The simulation results confirm that the rotor radial force is approximately zero and results from a balanced distribution of the magnetic flux density. The proposed DC excitation system is suitable to realize the rotor radial force cancellation in the bearingless BLDC motor. The simulation results of the proposed configuration show the approach of integrating winding configuration at different active pole positions to find the more efficient suspension performance and reduce the suspensions system current.

to describe the obstetric care developed in teaching hospitals (TH) in the city of Maceió-AL, intended for high-risk pregnancies. Retrospective cohort study performed between June and November 2018 with 291 women who received assistance with vaginal delivery, cesarean section, or abortion process in teaching hospitals selected as settings for this research. Data collection allowed the characterization of the interviewees as well as the assistance received and its relationship with obstetric violence. The analysis was performed using descriptive and analytical statistics with the aid of the Epi Info software (version 7.2.0.1) and measures that allowed the comparison of means and proportions. All women reported at least one violent situation, contrary to recommendations based on scientific evidence. It becomes necessary to optimize professional training to deconstruct obstetric care based on medicalization and pathologization of pregnancy and strengthen science-based care.

Segmentation and Classification of White Blood Cells Using the UNet.

In the bone marrow, plasma cells are made up of B lymphocytes and are a type of WBC. These plasma cells produce antibodies that help to keep bacteria and viruses at bay, thus preventing inflammation. This presents a major challenge for segmenting blood cells, since numerous image processing methods are used before segmentation to enhance image quality. White blood cells can be analyzed by a pathologist with the aid of computer software to identify blood diseases accurately and early. This study proposes a novel model that uses the ResNet and UNet networks to extract features and then segments leukocytes from blood samples. Based on the experimental results, this model appears to perform well, which suggests it is an appropriate tool for the analysis of hematology data. By evaluating the model using three datasets consisting of three different types of WBC, a cross-validation technique was applied to assess it based on the publicly available dataset. The overall segmentation accuracy of the proposed model was around 96%, which proved that the model was better than previous approaches, such as DeepLabV3+ and ResNet-50.
