Published: April 2021

Background: Seasonal agricultural workers group is one of the most disadvantageous groups of working life in Turkey same as many other countries. We aimed to determine the status of cardiovascular disease risk factors among migrant seasonal agricultural workers (MSAW) and to compare obtained data with local residents.
Methods: This study cross-sectional study was conducted among MSAW in Eskisehir, Turkey and closest town residents in 2015 during agricultural season. These 455 MSAW were living in camps composed of 20 or more tents. Local residents sample composed of 532 local residents were reached at their houses by using random sampling method with data acquired from health organization records. Both groups were subjected to same questionnaire.
Results: The prevalence of overweight/obesity among MSAW women was 40.5%, hypertension 19.9%, diabetes 4.9% and hypercholesterolemia 6.5%. These prevalences were 68.0%, 38.6%, 13.9% and 20.8% respectively among local residents. The prevalence of smoking risk among local residents was 1.5 times more than MSAW. In addition, the prevalence of overweight/obese risk was 4 times more; hypertension risk 1.8 times more, diabetes risk 3.8 times more and hypercholesterolemia risk 2.7 times more among local residents than MSAW (P<0.05).
Conclusion: The prevalence of cardiovascular disease risk factors of MSAW was lower than local residents in the study groups. Even though health risks that MSAW faced were more linked with environment and life conditions, cardiovascular disease risk factors should not be ignored. Health services should be guided by considering obstacles that MSAW experienced in accessing health services.

Published: April 2021

Background: To investigate the expression of miR-451a in prostate cancer tissues and its effect on prognosis.
Methods: Each of 78 specimens of prostate cancer tissues and corresponding adjacent normal tissues were collected from patients in Changshu Hospital Affiliated to Soochow University, Changshu, China from Apr 2014 to Jun 2015. Real-time quantitative RT-PCR (qRT-PCR) was used to detect the expression of miR-451a in tissues. The relationship between the expression of miR-451a and clinical pathological parameters was analyzed. The median expression of miR-451a in the experimental group was used to distinguish the high and low expressions of miR-451a in the experimental group. Kaplan-Meier was used to analyze the survival of miR451a high and low expression groups.
Results: The expressions of miR-451a in the patient's tissues and serum were decreased, and the correlation analysis found that they were positively correlated. ROC curve analysis showed that miR-451a had a high clinical value in the diagnosis of prostate cancer and the area under the curve was 0.921. The incidence of stage III+IV lymph node metastasis, Gleason score of >7 points and a serum Prostate-specific antigen (PSA) level of >20 ng/ml in patients of the low expression group increased significantly. The 5-yr survival rate of patients with low expression was significantly lower than that of those with high expression (P=0.005). MiR-451a was an independent factor affecting the prognosis of patients.
Conclusion: miR-451a is lowly expressed in prostate cancer, and patients with low expression have a poor prognosis.

Authors: Wang Yibing , Qu Xueling , Wang Haitao
Published: April 2021

Background: Entrepreneurs not only promote a nation’s economic growth but also increase employment. The risk of obesity among entrepreneurs may bring heavy economic burdens not only to the entrepreneurs but also to the national health care system. We aimed to examine the association between entrepreneurship and the risk of obesity.
Methods: We utilized data from the 2015 Harmonized China Health and Retirement Longitudinal Survey, including 2,802 individuals aged between 45 and 65 with complete data. This study used BMI (Body Mass Index) (kg/m2 ) as an indicator of obesity risk. Entrepreneurs were defined as those respondents who run their own businesses as main jobs. We used multivariate OLS regression models and Bayesian Markov Chain Monte Carlo (MCMC) method to examine the link of entrepreneurship and obesity risk.
Results: The multivariate OLS regression results showed that entrepreneurship was positively associated with BMI (P<0.01). The Bayesian MCMC results indicated that the posterior mean was (0.597, 90% HPD CI: 0.319, 0.897), demonstrating that entrepreneurship was indeed significantly positively associated with the risk of obesity.
Conclusion: Being an entrepreneur is positively associated with the risk of obesity. As obesity can cause diseases such as hypertension, diabetes, coronary heart disease and stroke, the health departments should take necessary health interventions to prevent entrepreneurs from being obese in order to increase their entrepreneurial success.

Authors: Liu Xun , Jiang Jiguo , Zhang Yanli
Published: April 2021

Background: The global outbreak of the novel coronavirus pneumonia (COVID-19) has seriously affected people’s work and lives. Disaster-related traumatic stress events increase the risk of substance abuse. Therefore, the COVID19 outbreak, as a stress event, inevitably has a negative impact on Chinese adolescents with Internet addiction.
Methods: In 2020, 1787 copies of the questionnaire were randomly distributed among adolescents aged 12–16 years in three communities in Shandong Province, China. Among the respondents, 121 Internet addicts voluntarily participated and were divided into the experiment group (60 members) and the control group (61 members). Logotherapybased mindfulness intervention was carried out on the experiment group. The effects of the intervention were analyzed after eight weeks of intervention.
Results: After the intervention, significant decreases occurred in the scores of Internet addiction and its five dimensions in the experiment group (P < 0.05), thereby implying better invention effects in the experiment group than the control group. The experiment group exhibited an increase in the positive coping score and a decrease in the negative coping score (P < 0.05). Significant decreases were found in the anxiety and depression scores in the experiment group (P < 0.05).
Conclusion: Logotherapy-based mindfulness intervention can significantly reduce the degree of Internet addiction among adolescents during the COVID-19 period, improve their positive emotions, reduce their negative emotions, and alleviate the degree of anxiety and depression in adolescents.

Published: April 2021

Background: Food insecurity can affect health directly or indirectly through its impact on nutritional status. We aimed at determining the effects of nutrition education intervention on household food insecurity in Zahedan, southeast Iran.
Methods: The study was conducted using multi-stage sampling method. The first stage was a cross-sectional investigation whereby 2,160 households were studied in Zahedan in 2015. The prevalence of food insecurity was determined and food-insecure households were identified. Household food security status was assessed through the 18-item US Household Food Security Survey Module. In the second stage, based on the determined sample size of 150 households in each group, eligible households were randomly divided into the intervention and control groups. Before the educational intervention, questionnaires including demographic and socioeconomic information were completed for both groups. Then, data analysis was performed and the intervention was conducted on the intervention group. Six months post-intervention, a final assessment was made by interviewing the two groups to complete demographic, socioeconomic, and household food security questionnaires.
Results: The prevalence of food insecurity in the 2,160 households was 58.8%. After the intervention, the number of food-insecure households diminished by 22% in the intervention group, and these households were assigned to the food secure category. After controlling the confounding variables, the educational intervention was significantly effective in reducing food insecurity score (P<0.001).
Conclusion: The findings demonstrated the beneficial role of nutritional education and the skills of resource management in modifying nutritional behaviors and improving food security in the study population.

Authors: Pilevari Nazanin , Valeh Shiva Mahyar
Published: April 2021

Background: The outbreak of the COVID-19 virus has had many destructive impacts on socio-economic and health systems. The health systems of countries could be supportive in crisis management, but they also are affected by the impact of the crisis, consequently, their operational level has declined. This study pursued resilience in an overall national health system under pandemic stress.
Methods: Based on WHO building blocks, by interviewing informants of the Ministry of Health and Medical Education, in Tehran-Iran, early 2021 a rich picture of the current situation depicted, the resilience model was extracted via a mixed method of Soft System Methodology (SSM) and total interpretive structural modeling (TISM). Dynamic capabilities were applied for the orchestration of the Iranian health system.
Results: Particular functional and structural suggestions applicable for designing a ubiquitous resilience model for the country-wide health system are presented in this study. The variables of crisis sensing, opportunity seizing, and reconfiguration are the cornerstones of health system resilience.
Conclusion: Well-suited health technology assessment (HTA) and health information system (HIS) play significant roles in the overall strengthening of the health system. All reforms for resilience will have a lasting result when the capabilities created by the resilience model are learned and reused in a dynamic cycle.

Authors: Zandkarimi Eghbal , Moghimbeigi Abbas , Mahjub Hossein
Published: April 2021

Background: Iran has ranked second in the frequency of cesarean delivery (CD) and this rate in 2014 has increased by 56 percent. The CD has multiple complications for the woman and newborn, and due to the women's readmission after surgery impose additional costs to the countries. Although CD has many complications and is not recommended by obstetrician and midwives; some factors affect the choice of this method of delivery.
Methods: We used data from the Iranian Institute for Health Sciences Research (IIHSR) in 2015. We studied the effects of factors such as socioeconomic and demographic factors and supplemental insurance status in the choice of CD. We used multilevel Zero-Inflated models for the modeling of data.
Results: The employed women resident in urban areas with the high-income and age greater than 34-yr old and supplemental insurance more likely chose CD. On the other hand, women with high education level, women who use at least one media (e.g. Radio, television, etc.) and women that use contraceptive methods have chosen the less CD.
Conclusion: Our findings highlighted the importance of supplemental insurance and socio-economic status in choosing a CD by women. However, in some cases especially in the rich class of society, the high cost of this type of delivery does not affect the choice decrease of it, and governments should adopt rigorous policies in using this method.

Published: April 2021

Background: We aimed to verify the association between blood group systems and prognosis of SARS-Cov-2 disease.
Methods: In this cross-sectional study, 329 patients infected with SARS-Cov-2 diagnosed based on their COVID-19 RT-PCR results and chest CT scans, were enrolled in the study. These patients were admitted to Kamkar Arab Nia Hospital, Qom, Iran from March to June 2020. Their blood groups and RH were determined, and demographic characteristics and clinical signs of patients were recorded. The patients’ temperature and peripheral capillary oxygen saturation levels (SpO2) were measured. Finally, the duration of hospitalization, intubation, and death rate were also analyzed.
Results: The results of the patients' blood group analysis were as follows: 129(39.2%) patients had A type, 66(20.1%) B type, 21(6.4%) AB type, and 113(34.3%) O type. Of 329 patients, 297 (90.3%) had Rh antigen. The dead cases were higher in O blood type at 13 cases (11.5%). Considering the positive and negative rhesus antigen, 31 (10.4%) and 1 (3.1%) were dead respectively, but the difference was not statically significant. As for the A group, the mean of admission duration (8.4±6.1 days) was not significantly different from the B group (8.8 ±7.2 days). AB group with a mean (7.4 ±4.4 days) was not significantly different from the O group (7.8 ± 5.4 days). There was no significant difference in the duration of hospitalization in RH patients, positive or negative. B blood group showed a significant association with the time interval to return to normal oxygen levels.
Conclusion: Blood type was not associated with COVID-19 death rate, nor was it associated with admission duration. B blood group showed a significant association with the time interval to return to normal oxygen levels.

Authors: Habiba Umme , TuzZohora Jui Fatema , Meem TaheraMahnaz , Kabir Farhad
Published: April 2021

Introduction: Presently, there has been an emergent concern that rising numbers of the world’s population are deserted due to the undesirable impacts of natural hazards, especially floods. Geographically, Bangladesh is a low-lying flood plain country with only a few hills in the south-east and the north-east part. Undoubtedly, education is a principal factor of socio-economic development, but regrettably, Bangladesh is suffering from the uncontainable effects of floods. After considering such issues, the foremost focus of this study was to recognize both the academic challenges faced by school-going children during a flood and examine the impact of the flood on the health of the children.
Methods: Interview schedule, questionnaire survey, and document analyses had been carried out for this study. The study design was carried out by applying a mixed method. Students of Biddanondokathi Government Primary School and Mangalkot Secondary School from Mirzapur village of Mangalkot union in Keshabpurupazilla were randomly selected. The well-structured questionnaires were disseminated to 80 respondents of two academic institutions of Keshabpurupazilla of Jashore district. Additionally, descriptive statistics and chi-square tests were conducted to attain research objectives.
Results: The outcome of this study revealed that flood unswervingly impacts the academic routine and health status of school-going children. Almost 93.8% of students faced academic challenges and 87.5% of children were the victims of waterborne diseases like diarrhea, skin diseases, and dysentery. Almost 82% of respondents did not go to school as the roads were impassable, 28.8% of individuals faced problems due to washed away bridges, and 28.8% faced challenges as their school was surrounded by water. About 66.2% of children dropped out of school and 17.5% of students did not attend their classes at all after the flood.
Conclusions: Not onlyschool-going children but also infrastructure is the crucial victims of flood disasters, compromising the children’s rights to access to quality education, information, good sanitation, as well as their participation rights. Flood disasters have key impacts on children’s education and progress and this study suggests that strategies need to be adapted to attend to the disaster risks encountered by school-going children of Bangladesh.

Authors: Neyestani Maral , Hazrati Raziabad Reza , Shavali Gilani Parisa , Shariatifar Nabi
Published: April 2021

Emulsions with a nanoparticle diameter are called nanoemulsions. Nanoemulsions actually refer to dispersed systems of different liquids. Nanoemulsions contain oil, water, and an emulsifier. Nanoemulsions have more prominent properties (they are more stable against droplet aggregation and biphasic) than emulsions. Due to these properties, it is more appropriate to use them in some foods and supplements. Also, the advantages of this method and the use of food-grade compounds in their preparation is a safe and appropriate method for the production of encapsulated food compounds and supplements. Nanoemulsions can be used in different fields of food technology and food supplements by increasing bioavailability, release control and preservation of compounds. The activity of some food ingredients and supplements such as vitamins, enzymes, synthetic and natural antioxidants, colors, synthetic and natural antibacterial, etc. can be maintained by using nanoemulsions for a longer period of time. Therefore, in this article, we have tried to examine various aspects of nanoemulsions, including existing preparation techniques and their various applications in food industry technology and food supplements.

Authors: Enunwaonye Hossanna Chimdi , Olugbade Adekunle Cyril
Published: April 2021

Outbreaks of food-borne diseases globally still exist and continue to generate public health concerns. This raises possible concerns that the extent of food safety regulation is not taken seriously among the regulation authorities, food handlers and even the consumers of food in markets and streets. Evidence of the impact of these food-borne illnesses exists and they pose not only health but also economic challenges on global health and national growth. This study aimed to examine the compliance with safe food hygiene practices and factors hindering compliance with food safety practices among food handlers in Benin-City, Nigeria. A descriptive cross-sectional study design was adopted in conducting this study. Total of 269 participants were recruited after ethical clearance from health authority in Benin-city. Data collection was with use of structured questionnaire and observational checklist. Retrieved data were coded and recorded in secured system, analysed using SPSS Ver.21. More than half (57.7%) of the respondents had poor compliance with (21.9%) having good compliance, while the rest (20.4%) had fair compliance. Also, majority of the respondents identified lack of potable water in cooking areas, lack of financial support and training as factors hindering their food safety compliance. Lack of compliance with food safety exist among food vendors in the markets. The relationship between the years of handling food, level of education of food handlers and compliance with food hygiene practices was statistically significant. Non-compliance with food safety exist among food vendors in the markets despite self-reported positive practices.

Published: April 2021

Objectives: The coronary endarterectomy combined with coronary artery bypass grafting (CABG) is an useful but still controversial surgical technique in diffuse coronary artery disease. The aim of this study was to analyze the operative and early postoperative outcomes of the patients who underwent CABG with and without coronary endarterectomy.
Methods: This retrospective study included a total of 312 consequtive patients undergoing on-pump CABG from December 2018 to December 2020 in the Department of Cardiovascular Surgery, Bursa Yüksek İhtisas Training and Research Hospital. Patients were divided into 2 groups as those who underwent coronary endarterectomy combined with on-pump CABG (Group 1, n = 48) and those who underwent isolated on-pump CABG (Group 2, n = 264). Peroperative variables were obtained from our hospital's computerized database and retrospectively analyzed.
Results: Previous percutaneus coronary intervention rate and the number of patients with diabetes mellitus was significantly higher in the endarterectomy group. The demographics and characteristics of the patients were similar between the two groups. The median number of distal anastomoses was 4 (2-5) in Group 1 and 2 (1-5) in Group 2. Median cross-clamp duration and perfusion times in Group 1 were longer than Group 2 (82 min vs. 63 min; p < 0.001 and 120 min vs. 95 min; p = 0.003, respectively). A total of 54 coronary endarterectomy practices were performed on 48 patients, and the LAD artery (73%) was the most endarterectomized vessel. In Group 1, postoperative 24 hours high-sensitive troponin I levels were significantly higher than in Group 2 (p < 0.001). There was no significant difference between the groups in terms of operative mortality, low cardiac output rates and perioperative myocardial infarction rates. Postoperative atrial fibrillation was significantly higher in Group 1 (p = 0.023).
Conclusions: Although coronary endarterectomy is a complex procedure, in patients with diffuse coronary artery disease, it is an essential and sometimes mandotary method in order to achieve complete revacularization and can be performed safely with acceptable operative and early postoperative outcomes.

Aim: The aim of this study was to compare the effects of dialysis type on right heart functions with two-dimensional speckle tracking echocardiography (2D-STE).
Material and Methods: A total of 53 patients who have peritoneal dialysis and hemodialysis, applied to cardiology and nephrology outpatient clinics, were included in the study. Those with left heart failure, coronary artery disease, primary and secondary pulmonary hypertension, pulmonary embolism, deep vein thrombosis, moderate and severe heart valve failure and stenosis were excluded from the study. Sociodemographic characteristics and biochemical parameters of the patients were recorded. Right heart functions of the patients were evaluated using 2D-STE.
Results: There was no difference between groups with respect to age (p=0.496), the rate of male was higher in hemodialysis group (p=0.006). In comparison of 2D-STE measurements; right atrium (RA) maximum volume and RA minimum volume were significantly higher in hemodialysis patients (p=0.006, p=0.007, respectively). There were no difference between the groups in RA maximum volume index, RA minimum volume index and tricuspid annular plane systolic excursion (TAPSE). RAS strain and RAA strain were significantly lower in hemodialysis patients (p=0.001, p=0.012, respectively). A positive correlation was found between TAPSE and RA maximum volume in hemodialysis patients (r=0.484, p=0.036), and between TAPSE and RA minimum volume in peritoneal dialysis patients (r=0.486, p=0.025).
Conclusion: Right ventricular functions were found to be similar in peritoneal dialysis and hemodialysis patients. It was observed that right atrial functions were better protected in peritoneal dialysis patients than hemodialysis patients.

Published: April 2021

Aim: Percutaneous imaging-guided core needle breast biopsy has become widely used as an alternative to incisional biopsy in the diagnosis of breast lesions. In this study, it was aimed to evaluate and report our core needle breast biopsy experiences performed with 14- and 18-gauge needles.
Material and Methods: Patients who underwent core needle breast biopsy between March 2012 and December 2019 in our radiology department and whose biopsy specimens were evaluated in the pathology department, of all age groups and both sexes, were included in this study. A total of 628 (615 female and 13 male) patients with breast masses were examined.
Results: The mean age of the patients was 52.20±13.94 (median= 51, range, 13-96) years, 90.4% (n=568) of the lesions were masses and the majority of lesions (53.2%, n=334) were 11-20 mm in size. The most of cases (47.2%, n=268) were BI-RADS 5. There was no significant difference between the two needles in terms of gender distribution, age, type of surgery, and core needle breast biopsy results. In 86.5% (n=141) of the patients, there was diagnostic accuracy between the surgical specimen and the core needle breast biopsy result.
Conclusion: We demonstrated that the 14-gauge and 18-gauge needles have similar performance of results. Smaller needles should be used for ultrasound-guided breast biopsies, which is less invasive, less painful, and creates less risk of hemorrhage. Moreover, no patient admitted to the emergency department because of the core needle breast biopsy acute complications such as hematoma, bleeding, etc. during this time.

Published: April 2021

As a practitioner with over twenty-five years of experience in the domain of education and training, educators at all levels of education face serious challenges while attempting to embrace technology in instructional processes. To cope with the new trends, educators in the field of education and professional training are challenged to update their skills and benefit from the flexibility offered by contemporary learning technologies. Based on the wealth of experience acquired while assisting institutions of learning at all levels of education to put their courses online, I thought it necessary to assist colleagues with a book entitled "Course Design for Technology Mediated Learning".

Course Design for Technology Mediated Learning is structured into seven chapters:
Chapter 1: Basic Notions of Learning Theories.
Chapter 2: Structure and Processes of the Human Memory
Chapter 3: Classification of Learning Domains and Objectives
Chapter 4: Instructional Design Models
Chapter 5: Searching Electronic Resources on Internet
Chapter 6: Learning Management Systems
Chapter 7: Basic Steps in Course Creation and Learners Enrolment in Moodle

It is important to note that the chapters are not organised in a hierarchical order thus providing you with a greater flexibility to explore each chapter independently based on your needs. However, it is important to walk through from chapter one. Even if you are familiar with the different topics, there might be something new. I believe in the psychology of learning which upholds that concepts are best mastered when we rehearse existing knowledge. With this in mind, this book provides an opportunity to rehearse what you already know. References for further reading have been provided at the end of each chapter thus making it easy for those who are interested in deepening their knowledge in the issues discussed.

Abstract:

The fish sorting process carried out by fishermen or sellers, to select fish based on quality is still using manual methods and sometimes misses due to the limited sense of sight when tired. So far the examination has only been seen physically. As a result, the fish will often be damaged when consumed. This study tries to apply the Convolutional Neural Network (CNN) algorithm to distinguish between fresh and non-fresh fish. Convolutional Neural Network is a method of deep learning that is capable of conducting independent learning processes for object recognition, object extraction, and object classification. In this study, the Convolutional Neural Network algorithm is applied to distinguish between fresh and non-fresh fish. Network learning process produces 100% accuracy of training data and data validation. Testing of testing data also results in 100% accuracy. The results of this study indicate that the use of the Convolutional Neural Network method can identify and classify fresh and non-fresh fish very well.

On the solution of the problem of synthesis of the control system for the process of dosed feed of electrode wire for arc welding equipment
Authors: Lebedev V.A.
Published: April 2021

Goal. Refinement of the methodology for the development of an effective control system for an electric drive with controlled relay-type regulators for organizing a metered feed of an electrode wire using the parameters of the arc process with the possibility of using it in design practice and practice of technological application. Methodology. The proposed method for the mathematical description (mathematical model) of the system of the developed structure electric drive - arc process with current feedback of welding with a variable structure device is based on the theory of automatic control as applied to nonlinear elements, the application of the theory of operational calculus. At the same time, a selection and description of a nonlinear node in the feedback circuit in the form of a relay element with a certain structure and subsequent linearization of this element was made. As an electric motor of the electrode wire feeder, a new development of a specialized valve electric motor is used, which is used in the system with a microprocessor controller. Results. Due to the presence of a substantially nonlinear link, the calculation of the valve electric drive system – the arc process can be found on the basis of a system of nonlinear differential equations, which is practically impossible for practical application. In this work, these complications are overcome on the basis of a rational choice of the description of the nonlinear link, its harmonic linearization and obtaining on this basis a mathematical description of the system, from which, using the methodology of operational calculus, the relations necessary for calculating the parameters of the system are determined in analytical form. Originality. The problem of calculating a rather complex problem of mathematical description of the valve electric drive system – a technological link in the form of an arc process with a substantially nonlinear link in the feedback circuit in the work is solved with the effective use of a set of methodological methods, which include as a means of representing individual links, including nonlinear links selected simplifications and solutions of the obtained differential equations using original methods of operational calculus. The proposed method (mathematical model) is tested in two directions – oscillography of a real system, as well as system simulation. Practical significance. Using the developed methods for describing the control system, it is possible to calculate its characteristics and, on their basis, select the parameters for setting the electric drive controller, which allows, without additional experimental research, to obtain the necessary character of the transfer of electrode metal, and, consequently, the quality of the result of the arc process.
New algorithm for energy dispatch scheduling of grid-connected solar photovoltaic system with battery storage system
Authors: Slama F. , Radjeai H. , Mouassa S. , Chouder A.
Published: April 2021

Purpose. In last decade the problem of energy management system (EMS) for electric network has received special attention from academic researchers and electricity companies. In this paper, a new algorithm for EMS of a photovoltaic (PV) grid connected system, combined to an storage system is proposed for reducing the character of intermittence of PVs power which infect the stability of electric grid. In simulation model, the PV system and the energy storage system are connected to the same DC bus, whereas EMS controls the power flow from the PV generator to the grid based on the predetermined level of PV power. In the case where the PV power is less than the predefined threshold, energy is stored in the batteries banc which will be employed in the peak energy demand (PED) times. Otherwise, it continues to feed the principal grid. The novelty of the proposed work lies in a new algorithm (smart algorithm) able to determine the most suitable (optimal) hours to switching between battery, Solar PVs, and principal grid based on historical consumption data and also determine the optimal amount of storage energy that be injected during the peak demand. Methods. The solution of the problem was implemented in the Matlab R2010a Platform and the simulation conducted on Laptop with a 2.5 GHz processor and 4 GB RAM. Results. Simulation results show that the proposed model schedules the time ON/OFF of the switch in the most optimal way, resulting in absolute control of power electric path, i.e. precise adaptation at the peak without compromising consumers comfort. In addition, other useful results can be directly obtained from the developed scheme. Thus, the results confirm the superiority of the proposed strategy compared to other improved techniques.
