Monte Carlo Method-Based Behavioral Reliability Analysis of Fully-Mechanized Coal Mining Operators in Underground Noise Environment

Sound is an important aspect in working environment, and underground strong noise environment imposes a serious impact on operators' physical and mental health and easily leads to people's unsafe behaviors, thus giving rise to accidents. How to quantitatively study operators' behavioral reliability is a study hotspot. To mitigate the noise impact on operators and reduce the occurrence rate of accidents due to human factors, the relational models between noisy working environment and human physiological indexes were established first through a laboratory simulation, and then a reliability integral model was obtained using performance function and limit state equation. Second, the established reliability integral model was numerically simulated based on Monte Carlo numerical simulation method to obtain its numerical solution, and operators' behavioral reliability values under different sound pressure levels (SPLs) on fully-mechanized coal mining face were calculated. The results show that the behavioral reliability of fully-mechanized coal mining operators is high with low accident occurrence rate under noise SPL of 50-70 dB. Under 70-90 dB, their behavioral reliability is 0.7092 with potential accident risks. The behavioral reliability is low when SPL is 90-110 dB, under which accidents may easily take place. This study manifests that operators' behavioral reliability analysis under underground noise environment based on Monte Carlo method is of certain feasibility. The conclusions have a certain guiding significance for relieving human physical and mental harms incurred by noise, improving human behavioral reliability, reducing human errors and guaranteeing safety production.
Optimization of ball screw transmission six-DOF platform based on error analysis

This study proposes an optimization method based on error analysis for ball screw transmission six-DOF platform (BSTSP). The error model of BSTSP has been built up based on the simpler error source model. According to the error model, the upon platform outputting error influenced by structural parameters has been computed. And the preferable range of the structural parameters is preliminarily identified. Then the upon platform outputting error is set as optimization objective function. The structure of BSTSP is optimized by using ADAMS based on error analysis. The optimal analysis results provide an important basis for improving the space position accuracy of BSTSP.

The Association of Myositis Specific Antibodies in Patients with Inflammatory Myositis: Preliminary Data in Indian Patients

Context: Autoantibodies have a role in the diagnosis and prognosis in Autoimmune Inflammatory Myositis (AIM). Aims: The aim of this work was to study the prevalence and clinical correlation of myositis specific and associated antibodies (MSA and MAA) in AIM. Setting and Design: This was a cross-sectional observational study. Methods and Materials: Consecutive AIM patents were divided into groups as dermatomyositis (DM), polymyositis (PM), CTD-associated myositis (CTD-M), cancer-associated myositis (CAM) and juvenile myositis (JM). Their data along with serum samples were collected after obtaining informed consent. Sera was analyzed for IgG antibodies against Jo-1, PL-7, PL-12, EJ, SRP, Mi-2, MDA-5, TIF1γ, SAE1, SAE2, NXP2 and SSA/R052kD using the microELISA technique. The institutional ethics committee approved the study. Statistical Analysis: SPSS software (version 24.0) was used. P value < 0.05 was considered statistically significant. Results: There were 48 patients (DM = 19, PM = 19, CTD-M = 5, CAM = 2, JM = 3) included. MSA were positive in 37.5% patients. Antibodies against Mi-2 were present in 6 (12.5%), Jo-1 in 5 (10.4%), 2 (4.1%) each had PL-7 and SRP antibodies. One patient (2%) each had MDA-5, NXP2 and TIf1g antibodies. Jo-1 antibody was associated with mechanic's hands and ILD. There was a significant association of rash in the Mi-2 group with none of the patients having ILD. Malignancy screening was negative in NXP2 and TIF1g antibody-positive patients. Ro52 was the most common MAA (33.3%) and was associated with mechanic's hand. Conclusion: MSA was present in almost 40% of the cohort. Anti Jo-1 antibody was associated with mechanic's hands and ILD. None of the Mi-2 patients had ILD, which may point to a protective role of this antibody for ILD. The association of newer antibodies in Indian patients needs to be further studied in larger cohorts.
β-HCG Level as a Predictive Marker of Pregnancy Progression or Retrogression

An ordered sequence of biologic events is precursors of the birth of a healthy baby. Hormonal interactions acting as a nexus between the fetus, placenta and mother that controls the establishment and progression of pregnancy and fetal development are very important. We examined the role of Beta-Human Chorionic Gonadotropin (β-HCG) as a predictive marker. Applying radioimmunoassay that utilizes anti-sera generated from specific β-submit of HCG we evaluated the serum β-HCG level in 60 pregnant women in the three trimesters. Results showed that there was consistent increase in concentration that drops gradually and maintained a plateau only to drop from the 40 th week of pregnancy. 3 subjects (5%) that had a sudden sharp drop in β-HCG level resulted in complications. Inclusion of β-HCG level screening and mon-itoring in pregnancy will raise assurance of progress or retrogression in pregnancy. We provide data that can be used as a reference range for β-HCG using this method.
The epistemic and pragmatic function of dichotomous claims based on statistical hypothesis tests

Researchers commonly make dichotomous claims based on continuous test statistics. Many have branded the practice as a misuse of statistics and criticize scientists for the widespread application of hypothesis tests to tentatively reject a hypothesis (or not) depending on whether a p-value is below or above an alpha level. Although dichotomous claims are rarely explicitly defended, we argue they play an important epistemological and pragmatic role in science. The epistemological function of dichotomous claims consists in transforming data into quasibasic statements, which are tentatively accepted singular facts that can corroborate or falsify theoretical claims. This transformation requires a prespecified methodological decision procedure such as Neyman-Pearson hypothesis tests. From the perspective of methodological falsificationism these decision procedures are necessary, as probabilistic statements (e.g., continuous test statistics) cannot function as falsifiers of substantive hypotheses. The pragmatic function of dichotomous claims is to facilitate scrutiny and criticism among peers by generating contestable claims, a process referred to by Popper as “conjectures and refutations. ” We speculate about how the surprisingly widespread use of a 5% alpha level might have facilitated this pragmatic function. Abandoning dichotomous claims, for example because researchers commonly misuse p-values, would sacrifice their crucial epistemic and pragmatic functions.
Applicability of the Functional Assessment of Anorexia/Cachexia Therapy instrument to assess quality of life in maintenance haemodialysis patients with cachexia

Background Many patients on maintenance haemodialysis (MHD) eventually suffer from cachexia. The Functional Assessment of Anorexia/Cachexia Therapy (FAACT) is a tool used to evaluate the quality of life of patients with cachexia related to various diseases, but its suitability for use in MHD patients has yet to be verified. This study aims to explore the applicability of the FAACT in MHD patients by conducting reliability and validity tests.Methods Qualified MHD patients were selected to complete the FAACT and Kidney Disease Quality of Life Short Form 36 (KDQOL-36) questionnaires, and their demographic data and biochemical test results were collected from electronic medical records. Then, statistical software was used to perform a reliability test, and Pearson correlation analysis was carried out with KDQOL-36 as the calibration scale. Finally, the patients were divided into groups to evaluate discriminant validity.Results A total of 299 patients were included in this study. The Cronbach’s alpha coefﬁcients of the FAACT and its anorexia-cachexia subscale (ACS) were 0.904 and 0.842, respectively, and their test–retest reliability exceeded 0.85. The correlation coefficients between the FAACT and its items ranged from 0.146 to 0.631, and the correlation coefficients between the FAACT and KDQOL-36 dimensions ranged from 0.446 to 0.617. The effects of cachexia status (present or absent) on FAACT and ACS scores had effect sizes of 0.54 (P＜0.001) and 0.60 (P＜0.001), respectively. The FAACT and ACS also significantly discriminated between patients with and without inflammation (P＜0.001). Conclusions The FAACT and ACS have acceptable reliability and validity in MHD patients and are suitable for measuring the quality of life of MHD patients with cachexia.

Accumulation and toxicity of lanthanum and neodymium in horticultural plants (Brassica chinensis L. and Helianthus annuus L.)

Accumulation and Toxicity of Lanthanum and Neodymium in Horticultural Plants Arefeh Rezaee Advisors: University of Guelph, 2016 Dr. Emily YW Chiang Dr. Beverley Hale In this study, the dose response of Brassica chinensis L. and Helianthus annuus L. to light rare earth elements (REEs), lanthanum and neodymium, were investigated in vitro. The phytotoxicity of the studied REEs was determined by measuring the aboveground and belowground biomass, and the chlorophyll concentration of the plants. The half maximal inhibitory concentration (IC50) in plant biomass and total chlorophyll concentration were estimated. The available ion species of La and Nd for plant uptake were determined through geochemical modeling. The concentration of these elements in the plants was measured to assay the ability of these plants to hyperaccumulate. Low dosages of La and Nd showed hormetic effects on the shoot and root masses of Helianthus annuus L. , while both elements at high concentrations were toxic to the species tested. Tissue content analysis result indicated that the plants were not effective hyperaccumulators.
Electronic Supported Solutions to Scale-up Maternal New-born and Child Health Interventions Feasibility Assessment for Hoima District

Background: The application of mobile telecommunication technologies in the improvement of Maternal New-born and Child Health for developing countries including Uganda is one of the key innovations in improving health outcomes. One of the key models used in disseminating health messages to mothers is the timed and targeted counselling (ttC) model. This model is being implemented in Uganda and it utilizes the services of Village Health Teams (VHTs) to drive change through mHealth. Understanding the feasibility of electronic supported solutions in scaling up Maternal New-born and Child Health intervention is critical at inception to guide resource allocation, understand existing strength, weaknesses, opportunities and threats to successful implementation of a mobiles health solution. Methods: Across-sectional study to collect quantitative and qualitative data from 432 VHTs was used. A census of 43 Health facilities was also done in Hoima district. Secondary data was collected from the District Health Team, Ministry of Health (MoH) and other relevant actors. The study followed the mHealth Assessment and Planning for Scale (MAPS) Toolkit self-assessment and planning guide designed to offer improvement of project capacity to pursue strategies that increase potential for scaling up and long-term sustainability achievements. A semi structured questionnaire was used which assessed the mHealth feasibility basing on the 16 domains under the 6 axes for the assessment for scale-up of an mHealth platform. Data was analysed at different levels from CommCare, and the District Health Information System (DHIS2) using SPSS. Results. 95.8% of VHTs owned a mobile phone and majorly used them for text messaging (71.3%). The biggest portion of VHTS use MTN network for voice calls or data services with accessibility findings of 88.8% and 86.2% respectively. Most health facilities (55.8%) had personnel trained in computer skills but only 46.5% are proficient in basic computer skills. From the analysis of the 6 axes, the functionality of the mHealth in Hoima district was at 42.6% with Axis 1 on ground work planning and implementation scoring highest with 63.9% and Axis 3 that focuses on Financing the mHealth platform scoring the lowest of 30.0%. Conclusion. For successful application of telecommunication mobile technologies, partnership between different actors needs to be up scaled to reduce on costs and maximize benefits. A deeper stakeholder analysis needs to be done for different organisations to be engaged in different elements that support the mHealth project.
Research into Silicon Nanoparticles as Agents for UHF Hyperthermia In Vitro

The current approaches to cancer treatment, including surgery and high-energy beam irradiation, do not always give satisfactory results for a number of oncological neoplasms. One of the promising areas in oncology is the use of nanoparticles selectively heated by external action as agents for hyperthermia of some types of tumors. In this work, we performed selective heating of suspensions of silicon nanoparticles using a device for electromagnetic high-frequency therapy (UHF-60).
Happiness: does it transform with age?

The ultimate goal of all our actions and desires is happiness. It is a pursuit that continues across the life span. But how does the experience of happiness vary as we age? This study aims to explore how the level of happiness varies across age and gender. A purposive sample of young adults, middle aged and old aged individuals were selected for the study. The Questionnaire for Eudaimonic Well Being (Waterman et al, 2010) and The Orientation to Happiness measure (Peterson, Park & Seligman, 2005) were administered as tools for data collection. The total sample comprised a total of 180 males and females. 3 x 2 factorial research design was applied in the present comparative and descriptive research study. Both Analysis of Variance (ANOVA) and Pearson’s Correlation were calculated to find the relationship between happiness and age. We found that with the increase in age, both orientations to meaning and pleasure increased, and this was supported by the finding that the young and old differed significantly with respect to meaning in life.
Original Research Paper FORMULATION AND EVALUATION OF ERYTHROMYCIN DENTAL IMPLANTS FOR PERIODONTITIS

Periodontitis is an inflammatory response to the overgrowth of anaerobic organisms in the subgingiva and if unchecked, results in the destruction of the bone and soft tissues supporting the tooth, which results in tooth loss. Erythromycin is a macrolide antibiotic that has an antimicrobial spectrum similar to or slightly wider than that of penicillin. Erythromycin has antibacterial activity and is used in the treatment of superficial infections caused by organisms susceptible to Erythromycin. In present work dental implants were prepared by solvent casting technique using glass moulds. Implants were prepared by dissolving Ethyl cellulose alone and with copolymers (HPMC K4M, Sodium Alginate) in chloroform and dichloromethane (1:1) solution, using dibutyl phthalate and PEG‐400 as plasticizers. These formulated implants were then evaluated for different parameters like uniformity of thickness, uniformity of weight, tensile strength of the films, folding endurance and in vitro drug release.
The somatosensory link: S1 functional connectivity is altered by sustained pain and associated with clinical/autonomic dysfunction in fibromyalgia

Chronic pain patients feel pain as a primarily somatosensory sensation, although it is well understood that clinical pain is much more than somatic and encompasses multiple affective and cognitive domains. Fibromyalgia (FM) is a prototypical functional pain syndrome characterized by multi-dimensional symptomatology. Symptoms include widespread pain, mood disturbance with significant pain catastrophizing, cognitive and physical fatigue, dysfunction of autonomic activity, and amplified sensitivity and temporal summation to experimental pain stimuli (1). Multiple neuroimaging studies have supported the theory that FM is primarily a multi-system disorder of central nervous system (e.g. brain) processing. However, the precise linkage between the circuitries processing somatic sensation with those underlying broader affective and cognitive domains remains unknown. Functional connectivity magnetic resonance imaging (fcMRI) is an adaptation of fMRI that may help assess brain circuitry supporting spontaneous clinical pain. While spontaneous clinical pain(2), and negative affect (3) components of FM have been linked to altered resting (or intrinsic)functional brain connectivity, previous studies have not systematically probed the primary somatosensory cortex (S1) – a potentially integral brain area for somatic symptomatology such as pain. In FM, decreased secondary somatosensory (S2) connectivity to primary motor cortex (3), and reduced connectivity between S2 and S1 (4) were also recently reported. Interestingly, S1 connectivity is also sensitive to sustained experimental pain stimulation in healthy adults (5), suggesting malleable state-like properties for S1 connectivity networks. This view is consistent with generalized reports that functional brain connectivity can reflect both state and trait processes (6). Such state processes may even underlie the hyperalgesia, allodynia, and temporal summation commonly noted in chronic pain patients, as region-specific changes in S1 connectivity may support maladaptive changes in central processing of somatosensory afference. Our current study investigated evoked-pain state induced alterations in S1 connectivity in chronic pain patients suffering from FM. We also explored how altered S1 connectivity is associated with clinically-relevant variables such as pain intensity and pain-related catastrophizing, key determinants of FM morbidity. Furthermore, we linked evoked deep-tissue pain modulated S1 connectivity with temporal summation of pain and core non-somatic aspects of FM pathophysiology including altered autonomic modulation. The latter investigation follows past studies that have noted autonomic dysfunction in FM patients (7), linking such dysfunction with clinically-relevant parameters (7, 8). We hypothesized that multi-system pathology, common to FM, is supported by altered functional S1 connectivity at rest and/or in response to evoked nociceptive stimuli highly relevant to FM patients – i.e. deep-tissue pain.
DECOMPOSITION OF ORGANIC DYES IN THEIR AQUEOUS SOLUTIONS UNDER ACTION OF ELECTRIC DISCHARGES OF ATMOSPHERIC PRESSURE

В обзорной работе рассматриваются процессы деградации органических красителей в их водных растворах под действием различных типов разрядов атмосферного давления. Эти процессы имеют важное значения для решения экологической задачи, связанной с очисткой воды от органических загрязнений. Дается краткое описание типов разрядов, используемых для этих целей диэлектрического барьерного разряда, импульсного коронного разряда, разряда скользящей дуги, тлеющего разряда постоянного тока, диафрагменного разряда, электролиза контактным тлеющим разрядом. Приводятся электрические параметры разрядов – напряжения, токи, вкладываемые мощности. Анализируются результаты по степени деградации более 30 типов красителей в разных типах разрядов. Обсуждаются особенности сравнения разных типов разрядов по их энергетической эффективности процесса деградации – энергии, затрачиваемой на разложение одного грамма красителя. Показывается, что для корректного сравнения результатов по эффективности разложения в разных типах разрядов требует задания, по крайней мере, одинаковой удельной мощности разряда, одинаковой начальной концентрации красителя и одного объема обрабатываемого раствора. Рассматриваются кинетические закономерности процесса разложения и влияние на них различных факторов – начальной концентрации красителя, мощности разряда, рН раствора, строения молекул красителя. Показано, что в большинстве случаев кинетика разложения описывается уравнением первого кинетического порядка по концентрации красителя. Обсуждаются возможности ускорения деградации с использованием гомогенных и гетерогенных катализаторов. Анализируются возможные механизмы протекающих процессов и участие в них активных частиц, образующихся в растворе под действием разряда (радикалов ОН, НО2, озона и других).
