This study was carried out to optimize a computational model of a new underground passive solar greenhouse to improve thermal performance, storage, and saving of heat solar energy. Optimized and conventional passive solar greenhouse were compared in regards of indoor air temperature, irradiation, and energy demand. Six different materials were used in the conventional model. In addition, TRNSYS software was employed to determine heat demand and irradiation in the greenhouse. The results showed that the annual total heating requirement in the optimized model was 30% lower than a conventional passive solar system. In addition, the resulting average air temperature in the optimized model ranged from −4 to 33.1 °C in the four days of cloud, snow, and sun. The average air temperature in the conventional passive solar greenhouse ranged from −8.4 to 24.7 °C. The maximum monthly heating requirement was 796 MJ/m2 for the Wtype87 model (100-mm lightweight concrete block) and the minimum value was 190 MJ/m2 for the Wtype45 model (50-mm insulation with 200-mm clay tile) in a conventional passive solar greenhouse while the monthly heating requirement estimated 126 MJ/m2 for the optimized greenhouse model. The predictability of the TRNSYS model was calculated with a coefficient of determination (R2) of 95.95%.

This study is focused on the influence of convective drying (50, 60, and 70 °C) and infrared (IR) power (250, 500, and 750 W) on the drying kinetics, the specific energy consumption of terebinth drying as well as quality and bioactive compounds upon various pretreatments such as ultrasound (US), blanching (BL), and microwave (MW). Compared to convective drying, IR drying decreased more the drying time and energy consumption (SEC). Application of higher IR powers and air temperatures accelerated the drying process at lower energy consumption (SEC) and higher energy efficiency and moisture diffusion. Terebinth dried by a convective dryer at 60 °C with US pretreatment showed a better color compared to other samples. It also exhibited the polyphenol and flavonoid content of 145.35 mg GAE/g d.m. and 49.24 mg QE/g d.m., respectively, with color variations of 14.25 and a rehydration rate of 3.17. The proposed pretreatment methods significantly reduced the drying time and energy consumption, and from the other side it increased energy efficiency, bioactive compounds, and quality of the dried samples (p< 0.01). Among the different pretreatments used, microwave pretreatment led to the best results in terms of the drying time and SEC, and energy efficiency. US pretreatment showed the best results in terms of preserving the bioactive compounds and the general appearance of the terebinth.

The study targeted towards drying of cantaloupe slices with various thicknesses in a microwave dryer. The experiments were carried out at three microwave powers of 180, 360, and 540 W and three thicknesses of 2, 4, and 6 mm for cantaloupe drying, and the weight variations were determined. Artificial neural networks (ANN) and adaptive neuro-fuzzy inference systems (ANFIS) were exploited to investigate energy and exergy indices of cantaloupe drying using various afore-mentioned input parameters. The results indicated that a rise in microwave power and a decline in sample thickness can significantly decrease the specific energy consumption (SEC), energy loss, exergy loss, and improvement potential (probability level of 5%). The mean SEC, energy efficiency, energy loss, thermal efficiency, dryer efficiency, exergy efficiency, exergy loss, improvement potential, and sustainability index ranged in 10.48–25.92 MJ/kg water, 16.11–47.24%, 2.65–11.24 MJ/kg water, 7.02–36.46%, 12.36–42.70%, 11.25–38.89%, 3–12.2 MJ/kg water, 1.88–10.83 MJ/kg water, and 1.12–1.63, respectively. Based on the results, the use of higher microwave powers for drying thinner samples can improve the thermodynamic performance of the process. The ANFIS model offers a more accurate forecast of energy and exergy indices of cantaloupe drying compare to ANN model.

Biodiesel is considered as a key prospective renewable energy source in India. Hence, a study was carried out for the improvement of palm kernel oil biodiesel production using a transesterification process at different molar ratios. This study comprehensively examined all aspects of biodiesel from optimum production to the effect of additives on its combustion behavior. The optimum yield condition was validated with the MINITAB-17 software and analyzed using the Taguchi method. Two different additives, 5% diethyl ether (DEE) and 2000 ppm Butylated hydroxyltoluene (BHT), were also experimented. Engine experiments were conducted at constant speed (1500 rpm) and five different engine loads (0, 25, 50, 75 and 100%) on a single-cylinder direct injection diesel engine. Heat release rate, brake specific fuel consumption, brake thermal efficiency, engine emissions, such as CO, HC, NOx, and smoke opacity were analyzed. The maximum palm kernel oil (PKO) biodiesel yields, obtained at 55 °C, for the KOH and NaOH catalysts were 86.69% and 75.21% at the molar ratio of 6:1. B20BHT combustion showed 4.6% higher brake thermal efficiency (BTE). NOx emission was reduced by 19.4%, compared to the diesel fuel values. DEE resulted in higher CO and HC emissions compared to diesel fuel values by 39.2% and 7.6%, respectively, whereas smoke emission was improved by 11.5%.

Background. Despite the availability of various guidelines, rules, and strategies, hand hygiene adherence rates among healthcare workers are reported significantly lower than expected. The aim of this meta-analysis is to determine the most effective interventions to improve hand hygiene and to develop a logic model based on the characteristics of the most effective interventions. Methods. A literature search was conducted on PubMed, ProQuest, Web of Knowledge, Scopus, Cochrane Library, and ScienceDirect databases up to December 21, 2019, with no time limit. Randomized clinical trials which had designed interventions to improve hand hygiene were reviewed. Data were extracted independently by two authors. All statistical analyses were performed using Comprehensive Meta-Analysis (CMA) software (version 2.0). A random-effects model was used to estimate odds ratios. Results. Although 14 studies were initially reviewed, only 12 studies entered the meta-analysis, since they had identified percentage rates of hand hygiene compliance. The most effective intervention (odds ratio 18.4, 95% CI (13.6–24.8)) was a multilevel strategy that influenced the determinants of hand hygiene behavior at individual, interpersonal, and organizational levels. Following this, a theory-driven logic model was mapped out to promote hand hygiene, based on situational analysis. Conclusion. This study suggests that designing integrated interventions based on a multilevel socioecological approach has the greatest potential to improve hand hygiene compliance in healthcare workers. The logical model proposed in this study can thus provide a useful guide for designing and conducting future experimental research.

Motivation determines the possibility of an individual's intention to accept health-related behaviors. Despite the important role of the motivational system in conducting healthy and safe nutrition behavior, this issue has not been adequately addressed. The purpose of this qualitative study was to explain the healthy and safe nutrition motivation system among Iranian adolescent girls. In this qualitative study, conventional content analysis was used and participants were selected using the purposive sampling method. Semistructured in-depth interviews were conducted with 42 adolescent girls in Shiraz, Iran. The interviews continued until data saturation was obtained. Qualitative data were analyzed using the Graneheim and Lundman qualitative content analysis by MAX-Q-DA (version 10) software. The data analysis resulted in three main categories for the participants' motivational factors for healthy and safe nutrition: (1) maintaining health and social functions, (2) maintaining the family's mental and economic health, and (3) achieving goals and success in life. The first category included two subcategories: “desire to have an appropriate look and appearance” and “fear of diseases and their complications.” The second category included two subcategories of “maintaining the family's mental health” and “maintaining the family's economic health.” The third category consisted of two subcategories: “desire to form a family and be successful in life” and “achieving the future career goals.” The motivation to maintain health and social functions, to maintain the family's mental and economic health, and to achieve goals and be successful in life has a powerful impact on the decisions and behaviors of adolescent girls to have safe and healthy nutrition. Therefore, recognizing the motivational system, as a key and determinative factor in developing the adolescents' intention to adopt health-related behaviors, is an effective step to design and develop successful interventions in promoting nutritional behaviors.

As well as causing a global health crisis, the COVID-19 pandemic has also generated multilevel social changes by damaging psychosocial and economic resources across Iranian society. Therefore, this qualitative study was conducted to examine and explain these social consequences and their impact on the social capital of Iran during the COVID-19 outbreak. Using a content analysis approach, nine experts participated in semistructured, in-depth interviews. Interviews were recorded and transcribed verbatim and analyzed using Lundman and Graneheim’s method. The social impacts of COVID-19 can be summarized into six categories and 32 subcategories. Three positive-negative categories emerged from the data analysis: “formation of new patterns of social communications; formation of new patterns of behavior; creation of economic changes.” Three entirely negative categories included “creating a climate of distrust; disruption of cultural, social, and religious values; psychosocial disorders.” Overall, most findings (27 out of 32 subcategories) indicated the destructive effects of the COVID-19 pandemic on social capital. Therefore, this raises concerns about social capital endangerment in Iran. However, positive social impacts can guide policies that strengthen social action and improve social capital.

Background: Many people spend more than a third of their post-maturation on work. Thus, workplace environment and climate have a great impact on individuals' lifestyles, and work environment brings a health perspective that provides a healthier lifestyle for employees. Objectives: The present study aimed to assess the staff's lifestyles and health behaviors as well as their relationship with organizational climate. Methods: This cross-sectional study was conducted on 404 employees from governmental departments in Shiraz in 2018. The data were collected using a three-part questionnaire, including demographic information, health-promoting lifestyle, and organizational climate questionnaires. Data were analyzed using the SPSS-25 software. Multivariate analysis of variance (MANOVA) was used to determine the significant relationship between demographic characteristics and organizational climate, and health-promoting lifestyle indices. The correlations between the lifestyle dimensions of health promotion and organizational climate were analyzed. Results: Age, education level, work experience, gender, and type of organization were the effective factors in the perception of organizational climate. In addition, work experience, type of organization, and the organizational climate governing the workplace were the determinants of the health-promoting lifestyle. The results revealed a significant, positive, weak correlation between the health-promoting lifestyle and organizational climate. A significant correlation was also observed between self-actualization and organizational climate (r = 0.290, P < 0.001). Conclusions: It is necessary to identify which individual and organizational characteristics should be improved to support the organizational climate to improve the health-promoting lifestyle.

Background and objective: Considering the worldwide increase in mental health problems among adolescents and the hypothetical positive impact of mental health literacy (MHL) on mental health promotive behaviours, this study examined the effect of a MHL intervention in a sample of Iranian high school students. Design: Educational intervention with a pretest–posttest and control group design conducted among Iranian high school students in 2019. Setting: Four public schools in Shiraz, Iran. Methods: In this study, 220 students (110 in each intervention and control group) were selected using the cluster multi-stage sampling and participated in the study. Participants completed the adolescent MHL questionnaire at two stages (pretest and posttest). A training programme which comprised six 60- to 90-minutes sessions using collaborative learning techniques and printed materials was conducted with the experimental group. Data were subjected to covariance analysis. Results: No significant differences were found between study groups regarding demographic and MHL scores before the intervention. After completing the training programme, the intervention group showed a significant improvement in MHL and subscale scores ( p < .01). Covariance analysis confirmed an improvement of MHL in the intervention group after controlling for pretest scores but not in the control group. Conclusion: Study findings demonstrated the efficacy of the training intervention to improve adolescents’ MHL. Further research is recommended to examine the effects of the same intervention among boys and longer-term outcomes.

The present study aimed to examine the effect of ultrasonic pretreatment and hot air, microwave–hot-air, infrared–hot air, and freeze-drying on the drying time, specific energy (SE), qualitative properties (i.e., color, shrinkage, and rehydration ratio), and bioactive compounds’ properties (i.e., antioxidant activity, phenolic, and flavonoid contents) of hawthorn fruit. Drying of hawthorn was conducted from 45 min for the ultrasonic + microwave–hot-air drying to 1280 min for the freeze-drying method. The lowest amount of SE was obtained using the ultrasonic-microwave–hot-air drying method, which was 47.57 MJ/kg. The lowest values in color changes (12.25) and shrinkage (17.21%) were recorded for the freeze-drying method, while the highest amounts for these traits were 45.57% and 66.75% in the HA drying, respectively. In general, the use of different drying methods reduces the antioxidant capacity (AC), total phenolic content (TPC), and total flavonoid content (TFC) during processing compared to fresh samples. The highest values for AC, TPC, TFC, and the rehydration ratio were 30.69%, 73.07 mg-GAE/gdw, 65.93 mg-QE/gdw, and 2.02 for the freeze-drying method, respectively.

Most agricultural products are harvested with a moisture content that is not suitable for storage. Therefore, the products are subjected to a drying process to prevent spoilage. This study evaluates an infrared rotary dryer (IRRD) with three levels of infrared power (250, 500, and 750 W) and three levels of rotation speed (5, 10, and 15 rpm) to dry terebinth. Response surface methodology (RSM) was used to illustrate and optimize the interaction between the independent variables (infrared power and rotation speed) and the response variables (drying time, moisture diffusivity, shrinkage, color change, rehydration rate, total phenolic content, and antioxidant activity). As infrared power and rotation speed increased, drying time, rehydration rate, antioxidant activity, and total phenolic content decreased, while the other parameters were increased. According to the results, the optimum drying conditions of terebinth were determined in the IRRD at an infrared power of 250 W and drum rotation speed of 5 rpm. The optimum values of the response variables were 49.5 min for drying time, 8.27 × 10−9 m2/s for effective moisture diffusivity, 2.26 for lightness, 21.60 for total color changes, 34.75% for shrinkage, 2.4 for rehydration rate, 124.76 mg GAE/g d.m. for total phenolic content and 81% for antioxidant activity.

In this research work, two intelligent methods, namely artificial neural networks (ANNs) and adaptive neuro-fuzzy inference system (ANFIS) are applied to predict the moisture ratio (MR), energy utilization (EU), energy utilization ratio (EUR), exergy loss and exergy efficiency of onion slices drying process by a Multi-Stage Semi-Industrial Continuous Belt (MSSICB) dryer. The experiments are carried out for various temperature levels (40, 55, 70 °C), air velocities (0.5, 1, 1.5 m/s) and belt linear speeds (2.5, 6.5 and 10.5 mm/s). The results demonstrate that by using the high levels of air temperature and velocity along with a low belt linear speed, the values of effective moisture diffusivity (Deff), color change (ΔE), EU, EUR, and exergy loss increase whereas the drying time, specific energy consumption (SEC) and exergy efficiency decrease. The highest values of Deff, SEC and ΔE are found to be 3.74 × 10−11 m2/s, 484.54 MJ/kg and 23.65, respectively. EU and EUR vary between 0.0641 to 0.2451 kJ/s and 0.0848 to 0.5028, respectively. Moreover, exergy loss and efficiency vary in the ranges [0.0182−0.0555] kJ/s and [62.33–89.25] %, respectively. Moreover, the results showed that the prediction accuracies of MR, EU, EUR, exergy loss and exergy efficiency by the use of ANNs model were 0.9995, 0.9957, 0.9984, 0.9960 and 0.9979, respectively so that the values of 0.9998, 0.9972, 0.9991, 0.9962 and 0.9985, obtained by application of ANFIS model, respectively. Therefore, the selected ANN and ANFIS models can be used confidently to estimate the exergy efficient drying conditions for a sustainable drying process by MSSICB.

Objectives. This study examined the validity and reliability of the Family Health Climate Scale (FHC-Scale) among Iranian families. Second, can it be attributed to other family members by measuring the health climate in one person? Method. In total, 261 female students and 196 mothers completed the FHC-Scale. The study instrument was a Persian version of the FHC-Scale prepared through a translation and back-translation process. Results. The results showed that the Persian version of the FHC-Scale is acceptable. Cronbach’s alpha coefficient for FHC-PA in female students and their mothers, respectively, was 0.88 and 0.86 for the whole scale. Cronbach’s alpha coefficient for FHC-NU in female students and their mothers, respectively, was 0.83 and 0.92 for the whole scale. The CVI values for all the items were equal to or above 0.8, and the CVR value for the total scale was 0.90. Conclusion. The Persian version of the FHC-Scale is therefore an effective tool for evaluating the different dimensions of family health climate in the Iranian population.

The present study examined the effect of ultrasonic pretreatment at three time the levels of 10, 20 and 30 min on some thermodynamic (effective moisture diffusivity coefficient(Deff ), drying time, specific energy consumption (SEC), energy efficiency, drying efficiency, and thermal efficiency) and physical (color and shrinkage) properties of kiwifruit under hybrid hot air-infrared(HAI) dryer at different temperatures (50, 60 and 70 °C) and different thicknesses (4, 6 and 8 mm). A total of 11 mathematical models were applied to represent the moisture ratio (MR) during the drying of kiwifruit. The fitting of MR mathematical models to experimental data demonstrated that the logistic model can satisfactorily describe the MR curve of dried kiwifruit with a correlation coefficient (R 2) of 0.9997, root mean square error (RMSE) of 0.0177 and chi-square (χ 2) of 0.0007. The observed Deff of dried samples ranged from 3.09 × 10−10 to 2.26 × 10−9 m2/s. The lowest SEC, color changes and shrinkage were obtained as 36.57 kWh/kg, 13.29 and 25.25%, respectively. The highest drying efficiency, energy efficiency, and thermal efficiency were determined as 11.09%, 7.69% and 10.58%, respectively. The results revealed that increasing the temperature and ultrasonic pretreatment time and decreasing the sample thickness led to a significant increase (p < 0.05) in drying efficiency, thermal efficiency, and energy efficiency, while drying time, SEC and shrinkage significantly decreased (p < 0.05).

Drying can prolong the shelf life of a product by reducing microbial activities while facilitating its transportation and storage by decreasing the product weight and volume. The quality factors of the drying process are among the important issues in the drying of food and agricultural products. In this study, the effects of several independent variables such as the temperature of the drying air (50, 60, and 70 °C) and the thickness of the samples (2, 4, and 6 mm) were studied on the response variables including the quality indices (color difference and shrinkage) and drying factors (drying time, effective moisture diffusivity coefficient, specific energy consumption (SEC), energy efficiency and dryer efficiency) of the turnip slices dried by a hybrid convective-infrared (HCIR) dryer. Before drying, the samples were treated by three pretreatments: microwave (360 W for 2.5 min), ultrasonic (at 30 °C for 10 min) and blanching (at 90 °C for 2 min). The statistical analyses of the data and optimization of the drying process were achieved by the response surface method (RSM) and the response variables were predicted by the adaptive neuro-fuzzy inference system (ANFIS) model. The results indicated that an increase in the dryer temperature and a decline in the thickness of the sample can enhance the evaporation rate of the samples which will decrease the drying time (40–20 min), SEC (from 168.98 to 21.57 MJ/kg), color difference (from 50.59 to 15.38) and shrinkage (from 67.84% to 24.28%) while increasing the effective moisture diffusivity coefficient (from 1.007 × 10−9 to 8.11 × 10−9 m2/s), energy efficiency (from 0.89% to 15.23%) and dryer efficiency (from 2.11% to 21.2%). Compared to ultrasonic and blanching, microwave pretreatment increased the energy and drying efficiency; while the variations in the color and shrinkage were the lowest in the ultrasonic pretreatment. The optimal condition involved the temperature of 70 °C and sample thickness of 2 mm with the desirability above 0.89. The ANFIS model also managed to predict the response variables with R 2 > 0.96.

This study aims to investigate the effect of different drying methods on the thermal, qualitative, and antioxidant properties and pH of terebinth. To perform the experiments in this study, the hot air (HA), infrared (IR), microwave (MW), hot air–infrared (IR–HA), and hot air–microwave drying (MW–HA) methods were considered. The results showed that the minimum drying time was obtained by the hot air–microwave (MW–HA) method. However, the lowest specific energy consumption (SEC) and the highest energy efficiency (ηe) were obtained by the MW method. Considering the color criteria, the best method was obtained by the MW–HA method. The highest amount of rehydration ratio (RR) and the lowest shrinkage (Sb) of the dried terebinth samples were obtained using the MW dryer compared with other drying methods. The MW and MW–HA methods resulted in higher contents of total phenol content (TPC), total flavonoid content (TFC), and antioxidant capacity (AntiOX) than other methods. According to the results of this study, the most effective drying method for terebinth was determined to be the MW and MW-HA methods.

In this study, the drying time, effective moisture diffusivity (Deff), specific energy consumption (SEC), and quality (color, shrinkage, and rehydration) of the ultrasound-pretreated (US) carrot slices were compared when dried by hot air drying (HD), microwave drying (MWD), infrared drying (INFD), and hybrid methods of MW–HD and INF–HD. Five mathematical models were considered to describe the drying kinetics in the carrots. The results show that US+MW–HD and INFD were the fastest and the slowest drying techniques compared to the HD technique with a 73% and 23% drying time reduction, respectively. The Deff ranged from 7.12 × 10−9 to 2.78 × 10−8 m2/s. The highest and lowest SECs were 297.29 ± 11.21 and 23.75 ± 2.22 MJ/kg which were observed in the HD and US+MWD, respectively. The color variation indices indicated that the best sample in terms of color stability was the one dried by US+MW–HD with the color variation of 11.02 ± 0.27. The lowest and highest shrinkage values were also observed in the samples dried by US+MWD and HD (31.8 ± 1.1% and 62.23 ± 1.77%), respectively. Samples dried by US+MWD and HD possessed the highest and lowest rehydration, respectively. Although the carrot slices dried at a higher pace by US+MW–HD (compared to US+MWD), the shrinkage and SEC of the samples dried by US+MWD were significantly lower than the US+MW–HD (p < 0.05). Therefore, it can be concluded that the application of the US+MWD method can be considered as a proper alternative for drying the carrot slices when compared to the HD, MWD, INFD, and hybrid methods.

The failure of classical techniques and algorithms have triggered researchers to search for stochastic tools capably of exploring the search space with constant convergence speed. Grey wolf optimizer (GWO) is a moderately novel stochastic algorithm with only a few parameters to regulate that can be easily employed for global optimization. For the first time, this study explored GWO to model biodiesel yield. It is worthy to note that, kerosene (KS) popularly known as paraffin oil has gained global attention in the aviation and biodiesel industries to improve cold flow properties and can be mixed with diesel in different proportions. Therefore, in this study, (1) Response Surface Methodology (RSM) and GWO were explored to model the waste sunflower oil methyl ester (WSOME)/biodiesel (BD) production from waste sunflower oil (WSO) and (2) Least square regression method was accosted to correlate the density of (0%KS + 100%BD), (5PKS + 95%BD), (20%KS + 80% BD), (50%KS + 50%BD) and (100%KS + BD) blends. The yield of WSOME (96.70%) was optimum at the methanol/oil molar ratio of 5.99/1, catalyst amount of 1.1 wt.% and reaction time of 77.6 min. The GWO model displayed a higher coefficient of determination, and a lower value of root mean squared errors compared to the RSM model. GWO predicted values, as compared to RSM, predicted yield indicates its reliability and usefulness for prediction without trial and error of conventional experimentation. The fuel properties concurred with the ranges of the ASTMD6751 and EN 14214 specifications. The quadratic relation with high regression coefficient (R2) was detected for the densities of (0%KS+100%BD) and (20%KS +80% BD) while the linear was found suitable for the densities of (5KS + 95%BD), (50%KS +50BD) and (100%KS+0%BD). The model and correlations can find application in biodiesel and aviation industries.

Background: Smoking is one of the greatest challenges for public health. It is estimated that 7% - 25% of adolescents have experienced smoking in Iran. Objectives: The present study aimed to investigate the viewpoints of high school male students, their parents, and teachers about smoking by adolescents based on four components of the social marketing mix. Methods: A qualitative study with a phenomenological approach was conducted via 12 focus group sessions in Persian language. To this end, 82 participants (30 students, 28 parents, and 24 teachers) were selected based on purposive sampling method in 2015.The data were analyzed through directed content analysis. Results: All the three studied groups viewed “looking older” as the major cause of adolescent smoking, other factors included getting others’ attention, looking smart person, calmness, decreasing pain, and attractive packaging of cigarette. Some differences were observed between the viewpoints of students, parents, and teachers about the complications of cigarette. The students focused on the social consequences of smoking, but the parents and teachers were more worried about its long term physical side effects and addictive properties. Unlike parents, the teachers and students considered imitating from parents and famous people as the main socio-environmental factor of smoking. All three groups believed that people’s negative social image and negative attention towards smokers should be included in smoking prevention educational programs. However, some differences were reported between their ideas in other educational subjects. Conclusions: Evaluating factors related to tobacco use from three different perspectives can provide a more comprehensive view of these factors and show the reason for the failure of many efforts to prevent student tobacco use and develop a more effective program to promote health.
