Switched Reluctance Motor (SRM) benefits from a simple, low cost, and robust structure. However, it exhibits high levels of torque ripple and vibration due to its non-uniform distribution of the flux ...and force densities in the air gap. To address this problem, a novel rotor with optimally designed flux barriers has been designed to be used along with a conventional SRM stator. In this paper, an optimization algorithm comprised of Genetic Algorithm (GA) and Finite Element Analysis (FEA) has been used to identify the best rotor geometry for maintaining average torque while minimizing torque ripple and tangential vibration of the stator. The performance of the optimized motor is then compared with a conventional SRM of the same size experimentally. The results show significant improvement in torque ripple as well as vibration for the new topology with no tangible drop in efficiency at high speeds.
Adherence to treatment is one of the major challenges in patients with HIV/ADIS. If the patients do not adhere, they will face recurrent consequences, such as disease progression. The aim of this ...study was to investigate the effect of information, motivation, and behavioral Skills (IMB) model on medication adherence, diet adherence, and physical activity in HIV/ADIS patients.
This interventional study was conducted on 122 patients with 20 years of age and over with HIV/AIDS in Kerman City, Iran, in 2018. A total of patients were selected by census method and categorized into the intervention and control groups. Later, a researcher-made questionnaire on IMB was used before and 3 months after the intervention to assess medication adherence, diet adherence, and physical activity .The intervention study consisted of at least 8 training sessions (90 min) over a 12-week period.
In adherence to medication, information (
= 0.034) and personal motivation (
= 0.003) constructs and in adherence to diet, information (
= 0.025), personal motivation (
= 0.001), self-efficacy (
= 0.010), and skills (
= 0.011) were significantly different between the two groups after the intervention (
= 0.011). However, regarding the adherence to physical activity, no significant difference was found between the two groups after the intervention.
The IMB model can be effective in promoting the diet adherence in HIV/AIDS patients. In this regard, more qualitative and quantitative studies are recommended on the adherence to medication and physical activity.
This descriptive-correlational study was conducted on 122 Iranian people living with HIV (PWHIV), who referred to a behavioral diseases counseling center in 2018. The AIDS Clinical Trial Group (ACTG) ...questionnaire was used to collect the required data. The study aimed to determine the level of medication adherence and its determinants in PWHIV.
About 75.4% (confidence interval 67.2%-82.8%) of the samples had a good combined antiretroviral therapy (cART) adherence and 74.6% (n = 91) of them were sure about the positive effects of medications on their health. Patients reported that most important reasons for medication non-adherence included forgetfulness, high drug dosage, lack of knowledge about ART value, and transportation problems.
Breast cancer (BC) is the most common malignancy in women. Identifying and avoiding the preventable risk factors of BC reduces its occurrence effectively. So, this study aimed to assess BC's risk ...factors and risk perception status in Babol, Northern Iran.
This cross-sectional study was conducted on 400 women aged 18 to 70 in Babol, Northern Iran. According to the eligibility criteria, the selected participants completed the demographic characteristics and researcher-made valid and reliable questionnaires. The statistical software was SPSS20.
The significant risk factors related to BC were old age (60 years old and more) (30.2%), obesity (25.8%), history of radiation (10%), and familial history of BC (9.5%), respectively (P < 0.05). Suspected symptoms of BC were observed in 78 (19.5%) women, including indentations in 27 (6.75%), redness in 15 (3.75%), pain in 16 (4%), and enlargement of lymph nodes in 20 (5%). The BC risk perception score was 107.72±13.22.
Most participants had at least one risk factor for BC. It is essential to implement intervention programs to control obesity and BC screening programs in obese and overweight women to prevent BC and its complications. Further studies are needed.
Introduction: Hypertension is the most important public health problem in developing countries. This study aimed to investigate factors associated with medication adherence of hypertension based on ...the health belief model.
Method: This was an analytical cross-sectional study. In this study, 403 hypertensive patients in Shahdad and Andoohjerd of Kerman were selected by census method. Data collection tools were a researcher-made questionnaire including the Health Belief Model (HBM) and Moriskyself-report questionnaire. Cronbach alph was 0.9. Then the data were analysed by SPSS vesrsion 24 and the significance level was P< 0.05. mean (SD), Frequency (percent) used to descriptive statistics and two Independent sample t-test, Mann-Whitney U test and Binary Logistic Regression were used for data analysis. All statistical analysis were done in SPSS 19 with significant level of 5 %.
Results: More than half of the patients (57.1%) had poor medication adherence. Most of the subjects (84.1%) used less than three drugs. Chi square test results showed a significant relationship between drug compliance and age group, education and job results of multiple logistic regression showed, three factors of awareness (OR=1.116, p =0.016), cues to action (OR=0.68, p =0.030) and perceived barriers (OR=0.83, p=<0.001) had significant effect on Medication Adherence .
Conclusion: Effective interventions based on the health belief model and with emphasis on raising awareness, practicing guide and removing perceived barriers can increase medication adherence in patients with hypertension.
Introduction. The growing rate of nonmelanoma skin cancer (NMSC) and melanoma has been a great challenge for global health system. The present research aims to determine sailors’ protective behaviors ...against the risks of sunlight and skin cancer in Iran. Materials and Methods. The present research was qualitative in type, and its data were collected from August to December 2019. To this aim, 23 participants were recruited with whom semistructured interviews were held. The data collection continued until data saturation, and the interviews were coded in MAXQDA 10. Conventional content analysis was used to analyze the qualitative data. Results. Analysis of sailors’ perceptions and experiences revealed 7 categories: protective behaviors, hard personal and familial conditions, social interactions, poor social support, feeling of satisfaction, self-care, and fear. Conclusion. Sailors are prone to skin cancer due to their specific work conditions. Perceptions and determinants of skin cancer and protective behaviors against sunlight were identified among sailors. Promotion of protective behaviors and beliefs that impeded preventive behaviors are among issues that require special attention.
