The Ni-B4C nanocomposite coatings were fabricated via pulse electrodeposition on a copper substrate, and the effects of pulse current density, duty cycle, and pulse frequency on the microstructure, morphology, and corrosion characteristics were assessed. Field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS) tests were employed. The baseline electrodeposition conditions were set at i = 1 A/dm², γ = 50%, and f = 10 Hz. Embedding B4C nanoparticles (NPs) into the nickel matrix significantly reduced the nickel crystallite size for the primary (111) and (200) crystal planes. Increasing the pulse current density from 1 to 4 A/dm² caused a substantial decrease in the incorporation rate of B4C NPs, from 5.5 to 2.9 vol.%. However, an increase in the duty cycle from 25 to 50% and the pulse frequency from 1 to 10 Hz raised the incorporation rate to 5.5 vol.% and 4.6 to 3.9 vol.%, respectively. Surprisingly, the incorporation of B4C led to an increase in the corrosion current density from 2.301 to 4.541 µA/cm². Increasing the pulse current density from 1 to 4 A/dm² and the duty cycle from 25 to 50% notably decreased the corrosion current density from 4.541 to 1.375 µA/cm² and from 7.243 to 4.541 µA/cm², respectively. Conversely, the minimum corrosion current density of 0.599 µA/cm², deposited at 1 Hz, increased significantly to 4.541 µA/cm² at 10 Hz, while the B4C NPs content increased from 3.9 to 5.5 vol.%, possibly due to a more uniform distribution of B4C NPs at 1 Hz. The Ni-B4C specimen deposited at 1 Hz exhibited a higher Rct compared to the pure nickel sample under baseline conditions, indicating strong consistency between the EIS and potentiodynamic results.

The production of oilseeds plays a significant role in saving currency, accelerating the process of economic development, security and food independence of the country. Camellia (Camelina sativa L. Crantz) from Brassicaceae family, is able to grow in different weather and soil conditions and requires less water, fertilizer and pesticides than other oilseeds. Therefore, the current research was conducted with the aim of introducing this plant and evaluating its yield potential and cultivation compatibility in Mazandaran.

This experiment was carried out as factorial based on randomized complete block design in four replications at Bayekola Agricultural Research Station (Mazandaran Agricultural and Natural Resources Research and Training Center). Six sowing dates (November 5, November 21, December 5, December 21, January 4 and January 19) and five planting distances (15, 20, 25, 30, and 35 cm) were selected as the study factors.

The results of analysis of variance showed that the treatments of planting distance and planting date had a significant effect on different traits of camellia plant. Plant height, number of sub-branches and biological yield were influenced by the interaction effect of the studied factors. The highest plant height values were observed on the planting date of November 15 and at 20 and 30 cm intervals (125.5 and 124.75 cm, respectively). Also, the characteristics of seed yield, days to flowering, days to maturity, the number of seeds in a pod and 1000 grain weight were affected by sowing date factor, and the traits of days to flowering, days to maturity and 1000 grain weight were affected by planting distance factor.

In the field of seed production and obtaining more seed yield, although the planting dates of November 5 to December 5 did not have significant differences with each other; but the planting date of November 21 is the best possible planting date due to the highest seed yield and the higher number of seeds in the pod. Also, the treatment combination of planting distance of 25 cm and planting date of December 5 with high biological yield can be a suitable treatment combination.

Nitrogen (N), an essential nutrient for growth and development of plants, is added to agricultural fields to boost crop yields, however, its applications limited in the aquatic ecosystems due to leaching. Accordingly, accelerated surface water eutrophication, and public health issues due to consumption of contaminated groundwater have been linked to enrichment of excess use of N that can be lost to the environment through leaching to the groundwater. These losses can be reduced by adoption of appropriate methods or best management practices, that increase the accessibility of N for plant use, enhance plants’ N uptake ability, and match nutrient applications with agronomic needs. Thus, improving N use efficiency through a combination of agronomic and soil management methods is critical for crop profitability and environmental management.One way to improve the efficiency of nitrogen fertilizer application and reduce its losses is the simultaneous use of organic and biological fertilizers along with chemical fertilizers. There are several ways to increase soil organic matter, but the most of these materials are not resistant to microbial decomposition and decompose quickly and lost from the soil. Biochar is one of the types of organic fertilizers, which is resistant to microbial decomposition.Biochar can affect chemical and biological N reactions in the soils. Biochar increase nitrogen use efficiency (NUE), influence nitrification rates and adsorption of ammonia, and improve NH+ accumulation by enhancing cation exchange capacity in soils.Nitration ofgroundwater due to improper use of chemical fertilizers and high leaching of nitrogen fertilizers and also low efficiency of nitrogen application in flood irrigation of rice, indicates the need for alternate management methods in rice cultivation, including changing irrigation methods and fertilizers types. The use of biochar fertilizer along with nitrogen-fixing bacteria in rice irrigation rotation can be a good solution to reduce the mentioned problems.

Materials and Methods :

This research was conducted at the research fields of the Sari Agricultural Sciences and Natural Resources University (SANRU) in 2017. The experimental site is located at 36º 39ʹ42ʺ N latitude and 53º03´54ʺ E longitude with -11 m above sea level. Soil samples were taken from depths of 0-30 cm before land preparation. The experiment was done in split split plot arrangement based a complete randomized blocks design with three replications. Two irrigation regimes (flooding and irrigation regimes) was the main plot. Nine fertilizers levels (100% of recommended nitrogen or N100, N100+ 10 ton biochar or biochar 10, N100+ biochar 20, N75, N75+ biochar 10, N100+ biochar 20, N50, N50+ biochar 10 and N100+ biochar 20) and seedling inoculation with Azospirillum lipoferum (without inoculation was also included as control) were sub and sub sub plots, respectively.

Results showed that biochar and nitrogen fertilizers, irrigation methods and also seedling inoculation with bacteria had significant effects on NUE, the amount of nitrogen and protein in the rice grains. Mean comparison of combination effects showed that consumption of 20 tons of biochar along with N50 or N75 had the greatest effect on NUE and the amount of nitrogen and protein in the grain, and the lowest amount of these traits was recorded in plots with N100 and no application of biochar. On the other hand, the highest level of nitrogen efficiency indices was obtained when 20 tons of biochar applied with N50 or N75 while the lowest amount of nitrogen use efficiency indices was obtained by using N100 and no biochar consumption.

 It seems that biochar improves nitrogen uptake by the rice plant by maintaining nitrogen in the soil and consequently increases the concentration of nitrogen in the grains and rice plants organs. There was no similar trend for effect of biochar on nitrogen uptake when fertilizer application rates increased.

Drying is a common technology that provides a long post-harvest storage period for products such as cantaloupe. Hot air drying is a method that, if the conditions are optimized, gives the product better appearance and improved textural properties. In this study, drying time, specific energy consumption, energy efficiency, shrinkage, rehydration ratio, changes in total color, phenol and antioxidant content were modeled to optimize drying factors (air temperature and air velocity) using the response surface method. The drying processes of the samples were investigated at three temperature levels of 50, 60 and 70 °C and three velocity levels 0.5, 1 and 1.5 m/s. For optimization of the drying conditions (drying time, SEC, energy efficiency, shrinkage, RR, color changes, TPC and AC), the influences of two levels of independent variables including air temperature and air velocity were assessed by response surface method through a face-centered central composite design. The results showed that in the drying of cantaloupe using the hot air method by increasing the inlet air temperature and decreasing the air velocity, energy efficiency, rehydration ratio, total phenol content and antioxidant were increased, while drying time, specific energy consumption, shrinkage and color changes were reduced. The optimum point for drying cantaloupe samples was obtained at an air temperature of 70 °C and air velocity of 0.5 m/s. The results showed that drying at higher temperatures increases the desirability index of the model obtained from the response surface method. The authors believe the outcomes of the present study can be used as a framework for choosing efficient drying parameters for drying cantaloupe or similar fruits in HAD systems

Cultivation of medicinal and aromatic plants has had long a special rank in the traditional agricultural systems of Iran and these systems have played an important role in creating diversity and sustainability. Management of soil nutrients using organic fertilizers is among major pillars of sustainable agriculture. Peppermint (Mentha piperita L.) is a medicinal plant, which proper nutrition and absorption of mineral elements play an important role in increasing its quantitative and qualitative performance. The high cost of fertilizers in farming systems, soil pollution and degradation of soil are factors that caused to full use of available renewable nutrient sources of plant (organic and biological) with optimal application of fertilizers in order to maintain fertility, structure, biological activity, exchange capacity and water-holding capacity of the water in soil. The global approach to balance nutrition and the production of medicinal plants, towards the use of sustainable agricultural systems and the use of management methods, such as application of biofertilizers, is improvement the quantitative and qualitative performance of these plants. So, the use of natural inputs such as organic and biological fertilizers seems to be a good way to move towards a sustainable production system. Accordingly, due to the possible effect of organic fertilizers such as biochar and vermicompost and biological fertilizers like mycorrhizal fungi and plant growth-promoting bacteria on the quantity and quality of peppermint essential oil, this research was carried out under organic conditions.

The present research was conducted as factorial layout based on a randomized complete block design in three replications at Sari Agricultural Sciences and Natural Resources University in 2017. The experimental site is located at 36º 39ʹ42ʺ N latitude and 53º03´54ʺ E longitude with -11 m above sea level. Soil samples were taken from depths of 0-30 cm before land preparation. Treatment consisted biochar on two level (0 and 10 ton ha-1) and organic and biological fertilizers on five level (no fertilizer, vermicompost (10 ton ha-1), Pseudomonas fluorescens, Azotobacter and Arbuscular mycorrhizal (Glomus mosseae, G. intradices and G. etunicatum. Weeds and pests were controlled mechanically or by hand and no herbicides or pesticides were used. The measured properties also included the pepermint yield, essential oil and essential oil compounds.

The results of analysis of variance showed that the simple effects of biochar and organic and biological fertilizers had a significant effect on the shoot fresh weight at 1% of probability level, while the interaction effect of experimental treatments on this trait did not have significant effect. According to the results, application of 10 ton ha-1 of biochar, caused a 42.96% increase in shoot fresh weight compared to no application. In the study of the simple effect of organic and biological fertilizers on shoot fresh weight, the results showed that the highest and lowest ones were obtained with mycorrhiza application and control (no application of organic and biological fertilizers) with an average of 667.95 and 418.08 g m-2, respectively. The highest shoot dry weight with an average of 89.08 g m-2 was associated with the combined use of biochar and mycorrhiza and the lowest one belonged to the control (no application of biochar and organic and biological fertilizers) with an average of 61.76 g m-2. The results also showed that the interaction of biochar and organic and biological fertilizers on essential oil compounds such as Menthone, Menthol, α-Pinene, Cineol-1,8, iso Menthone, Pulegone, Piperitone oxide, Menthyl acetate and Menthofuran was significant.

In general, the results showed that the use of biochar and biological and organic fertilizers can be effective in both the quality and quantity of peppermint essential oil, when the highest percentage of essential oil and the most peppermint essential oil compounds were obtained in treatments with application of biochar and biological and organic fertilizers. Where, the use of the bacterium Azobacter and Pseudomonas with biochar had the greatest effect on the quality of peppermint essential oil, especially in Menthol and Menton compounds. Finally, it can be concluded that the combined use of biochar with biological fertilizers has a significant impact on the quantitative and qualitative increase of peppermint essential oil in ecological or low input agricultural.

Backgrounds and Objectives:

Direct seeding is being developed in many Asian countries as a new technology that farmers are tending to use this technology in current years considering that it has appropriate economic efficiency, faster and easier cultivation, less labor force, more mechanization and shorter growth period than transplanting cultivation and due to discontinuous irrigation, less methane emission. But what makes it mainly obstacle are weeds.The use of seed priming can be one of methods that it can compensate the paucities of direct seeding and get promote seed quality. Seed priming also can active the initial germination mechanisms before planting and many benefits were mentioned for this treatment that the most significant of them is increasing the percentage and rate of germination. Indeed these plants expand their root system in shorter period of time compared untreated seeds. They are also reached to autotroph stage earlier by absorbing more water, nutrients and producing photosynthetic part. 

Materials and Methods:

The field experiment was conducted in Neka in 2018. The experiment was performed as a factorial in randomized complete block design in three replications. Experimental treatments include  seed priming in four levels 1- no priming, 2- hydropriming (priming with water), 3- priming with humic substances (10 g per 1.5 liters of water) 4- priming with auxin hormone (1.5 cc in 1.5 liters of water) and also, weed management at five levels 1- no weeding, 2- council active herbicide (15 g per 20 liters of water), 3- twice weeding (one month after planting + before the earing stage), 4- council active herbicide (15 g per 20 liters of water applied about one month after planting) + weeding (1.5 months after planting) and 5- complete weeding (weeding of all weeds during the growing season). 

Results:

Based on the results, by applying seed priming with humic acid, the maximum plant height, ear length and number of plants m-2 were obtained and complete weeding caused the maximum plant height, fertile tiller, total tiller and ear length. Also, seed priming with humic acid along with complete weeding caused the highest filled grain number (79.67 number) and total grain number (90 number), 1000-grain weight (23.47 g), grain yield (2327 kg ha-1), biological yield (11220 kg ha-1). Based on total weed density and biomass, in all three stages of sampling, the lowest amount of weed biomass and density was obtained with application of humic acid priming along with council active herbicide + weeding, which was not significantly different from application of humic acid priming and twice weeding and application of auxin with council active herbicide + weeding and twice weeding. Overall, the findings of this study indicate the effect of priming of rice seeds especially with humic acid and auxin along with council active herbicide + weeding and twice weeding, on reducing the weeds density and biomass as well as increasing the yield and yield components of rice in direct cultivation. 

Discussion:

According to results which were obtained this research and evaluation of yield and yield components are identified that application of herbicide cannot control the weed solitary. This research was showed that application of council active herbicide + weeding and twice weeding cause to reduce the weeds density and biomass as well as increasing the yield and yield components of rice in direct cultivation and also own to elimination of competing species, they improve the crop growth. Therefore, mechanical weeding, which is a non-chemical method of weed management, should be considered as a necessary part of sustainable agriculture.

This study is aimed to investigate the effect of a Hybrid Hot air-Microwave- Rotary Drum (HMRD)  dryer on the thermal properties, quality, and nutritional characteristics of green pea under different operational conditions. The experiments were conducted under different air temperatures (40, 55, and 70 °C), microwave power (90, 270, 450, and 630 W), and drum rotation speeds (5, 10, and 15 rpm). The thermal properties (e.g. drying time, effective moisture diffusion coefficient, activation energy, and specific energy consumption), quality features (color, shrinkage, and rehydration ratio), and nutritional properties (antioxidant activity and total phenol content) were determined. The results indicated that by increasing the microwave power, air temperature, and drum rotation speed, the drying time will decline. The highest diffusion coefficient and energy consumption were determined as 5.0410-11 m2/s and 109.91 MJ/kg, respectively. The lowest changes in color, shrinkage, and rehydration were calculated as 41.34, 24.08%, and 1.57. The highest total phenol (14.02 mg GAE/g d.w) and antioxidant (85.86%) were obtained. Thus the newly designed dryer can be employed for drying granular products and lead to satisfactory results.

This experiment was performed to investigate some morphological traits, yield and yield components of rice cultivars under direct cultivation conditions in competition with weeds.

The experiment was conducted in 2019 in Sari as a factorial in a randomized complete block design with three replications. Experimental factors included five rice cultivars (Tarom Hashemi, Neda, Shiroodi, Keshvari and Line 08) and two levels of weed competition (competition and non-competition with weeds).

The results showed that weed control had a significant effect on important traits such as number of fertile tillers, flag leaf weight, weight of other leaves, stem weight, 1000-seed weight, number of seeds per plant and rice grain yield, highest yield Seed was observed in weed weeding conditions in Shiroodi cultivar (5312 kg . ha-1) and the lowest grain yield was in the country cultivar with grain yield of 313.4 kg . ha-1 In weed weeding conditions, the highest grain yield was in Tarom cultivar. Hashemi was observed with 429.9 kg . ha-1 and the lowest grain yield was obtained in the country cultivar with the amount of 0.62 kg . ha-1.

In general, weed interference in direct cultivation can occur between 73 to 91% loss of rice grain yield, which indicates the need for effective weed control in this crop system. Also, it seems that among the studied cultivars, Shiroodi cultivar is a more suitable cultivar for direct rice cultivation if weed control.

The tendency to produce aromatic and medicinal plants and the demand for natural products is increasing especially in the world. Ecological agriculture (Agroecology) of medicinal plants guarantees their quality and reduces the possibility of negative effects on their quality and yield. Evaluation of different plant nutrition systems is one of the most important principles in the production planning of medicinal plants in order to achieve high yield and quality of effective ingredients. Proper fertilizer management is one of the most important factors in agricultural production. Identification of fertilizers which are compatible with nature and are suitable for plant growth could have favorable effects on quantitative and qualitative indices of the plant. Organic fertilizers are genuine and risk-free products that could be suitable for agricultural sustainability. Soil organic matter improves fertility and water retention, provides proper ventilation, long-term storage of plant nutrients and microorganisms, so replacing chemical fertilizers with fertilizers such as vermicompost and biofertilizer can reduce the above-mentioned effects. Biofertilizers are one of the operations that is nowadays in accordance with the principles of sustainable agriculture for soil fertility. Biofertilizers include the compost of one or more types of useful soil organisms or as metabolic by-products of these organisms that are used to provide the plant with the nutrients it needs in an agroecosystem.

In order to investigate the effect of biochar, organic and biological fertilizers on the quantity and quality of Ocimum bacilicum L., a factorial experiment was done in a randomized complete block design with three replications. Experimental treatments included two levels of biochar (0 and 20 ton ha-1) and five levels of fertilizers (vermicompost (10 ton ha-1), Mycorrhiza, Azotobacter, Pseudomonas and no fertilizer application). Prior to planting sweet basil seed, biofertilizers and vermicompost were mixed with soil to the depth of 15 cm. Mycorrhizal fungi were mixed with seed. Azotobacter and Pseudomonas bacteria were also incubated with seeds (seed inoculated). It should be added that in this study no chemicals were used to control weeds and pests.

According to the results, the highest plant height and number of main branches were obtained in biochar application with vermicompost (49.37 cm and 7, respectively), which was significantly better than other treatments. The interaction effect of biochar and fertilizer had a significant effect on fresh and dry weight of leaf and stem. Mean comparison of treatments showed that the highest leaf and stem fresh weight were obtained in biochar + Pseudomonas application (792 and 876 g m-2, respectively), which had no significant difference with biochar + vermicompost; and also, the maximum leaf dry weight and stem dry weight were obtained in biochar with Pseudomonas application (166 and 175 g m-2, respectively). The interaction between biochar and fertilizer on phenol, flavonoids and antioxidant activity of basil showed a significant differences between treatments.

In general, the results showed that the use of biochar and biological and organic fertilizers could be effective in both the quality and quantity of sweet bail, where, the use of the bacterium Azobacter and Pseudomonas with biochar had the greatest effect on the quality and quantity of sweet bail. Finally, it could be concluded that the combined use of biochar with biological fertilizers had significant impacts on the quantitative and qualitative traits of sweet bail in ecological or low input agricultural.

The present study investigates the effect of combined application of biochar, Azospirillium lipofrom bacteria and nitrogen in two flooding and intermittent irrigation methods on yield and yield components of rice (Oryza sativa L. cv. ‘Tarom Hashemi’). The experiment is done in split-split plot arrangement based on a complete randomized block design with three replications at the research farm of Sari Agricultural Sciences and Natural Resources University between two consecutive years of 2017 and 2018. The treatments are two irrigation methods (flooding and alternation irrigation regimes) as main plot and nine fertilizers levels (100%, 75%, and 50% nitrogen in combination with control (without biochar), 20 and 10 tons of biochar per hectare) and seedling inoculation with Azospirillum lipoferum (inoculation and non-inoculated control) as sub and sub-sub plots, respectively. According to the significance of the studied factors’ effects on the measured traits, application of 20 tons of biochar along with 75% to 100% of the recommended nitrogen show the greatest impact on rice yield and yield components in both intermittent and flooding irrigation methods. Since, the effectiveness of biochar in imtermittent irrigation is more significant, it can be concluded that the application of 20 tons of biochar per hectare plus 75% to 100% of the recommended nitrogen could greatly compensate the yield reduction due to reduced water consumption in intermittent irrigation, compared to the flooding irrigation.

Garlic has many medicinal properties in the food industry. In this study was investigated the effect of ultrasonic pretreatment (10, 20 and 30 min) on some thermodynamic and physical properties of dried garlic at thicknesses (2, 4 and 6 mm) using microwave at different power (100, 200 and 300 W). 10 mathematical models were used to describe the moisture ratio during garlic drying. The obtained results from this investigation showed that specific energy consumption (SEC) decreased significantely (p < 0.05) with increasing ultrasonic time, microwave power as well as with decreasing the thickness of samples. Fitting the mathematical models to the moisture ratios with the experimental data showed that the Logistic model can satisfactorily satisfy the drying curve of the samples in a microwave dryer with ultrasonic pretreatment with high correlation coefficient (R2 = 0.9996), minimum root mean square error (RMSE = 0.0113), and chi-square (χ2 = 0.0009) to describe. Effective moisture diffusion coefficient of the dried samples was found to be 8.04×10-11 to 1.64×10-9 m2/ s. The highest and lowest SEC was 340 and 35.87 kWh/kg, respectively. The results showed that increasing the microwave power, ultrasonic time, and decreasing thickness of the samples reduced significantely (p < 0.05) the shrinkage. By decreasing the microwave power and thickness of the samples as well as increasing the ultrausonic time, reduced significantely (p < 0.05) the color value.

The largest share of greenhouse gases in the world is related to the use of fossil fuels in power plants for electricity generate. Production and emissions of greenhouse gas are more important for the drying process that has high specific energy consumption (SEC). In this study, modeling and optimization of SEC and greenhouse gas emissions including CO2 and NOx during the process of blackberry drying under infrared-hot air combined dryer (at three inlet air temperature levels 50, 60 and 70 ° C) with different pretreatments including of microwave (90, 180 and 360 w), blanching (70, 80 and 90 ° C) and ultrasond (15, 30 and 45 min) were evaluated by response surface methodology. The drying energy was provided by various steam turbines, gas turbines and combined plants using natural gas, heavy oil and gas oil as fuel. The results showed that by increasing the microwave power and ultrosond time decreased quadraticly the amount of SEC (from 185.55 to 55.53 kWh/kg). However, this value decreased linearly (from 208.08 to 88.56 kWh/kg) with increasing blanching temperature. Emissions amount for all greenhouse gas decreased quadraticly (from 194460.67 to 24987.97g for CO2 and from 1074.36 to 106.06 g for NOx) with increasing microwave power, ultrosound time and hot air tepmerature for all turbines with different fuels. However, this amount decreased linearly with increasing blanching temperature (from 218063.85 to 39985.54g for CO2 and from 1204.76 to 169.72 g for NOx). Based on modeling using RSM, optimum conditions for the minimum SEC were determined to be microwave power of 349.7 W and inlet air temperature of 69.8 oC for microwave pretreatment, ultrasound time of 45 min and inlet air temperature of 70 oC for ultrasound pretreatment, blanching temperature of 90 oC and inlet air temperature of 70 oC for blanching pretreatment with disierability mean of 99.8%.

The Holy Quran, as a miraculous miracle, has spoken in various surahs of the movement of the sun. Experimental science has also studied the motion of the sun. The question is, in terms of Quran commentators, what motions are spoken? How are the definitive findings of empirical science with the views of the commentators? The apparent difference between some verses such as Bakhtar / 258 and .. How is Saghar correct with the definitive findings of experimental science?The hypothesis of this research is not only the correspondence of the definitive findings of science, but also the scientific miracle and scientific spectacle of the Qur'an in some way of the movement of the sun.The research methodology is the data collection method and the library study and analysis of the content of the data.In this research, it was determined that the sum of verses related to the motion of the sun is divided into two categories. In the descriptive verses, the aspect of the scientific miracle of verses, such as: the moving of the Sun (Imari Lajel Masami), the wise state of movement (al-Shams and al-Qamar al-Fayl-i-Bashoon), the transitional-longitudinal movement (al-Shams-e Tazari, Lhashtar Lah, Dhlqqat al-'Aziz al-Alim) There is a long-range movement along with the galaxy (and al-Shams and al-Qamar al-Fayl-i-Bilak). The second verses of the second category have apparent inconsistencies with the definitive findings of empirical science, but with regard to the cornea of the authority, the industry of controversy and its conditions, there is no conflict between expression and empirical findings.

In this research was investigated the impact of various pre-treatments on effective moisture diffusivity coefficient (Deff</sub></em>), specific energy consumption (SEC</em>), total color difference and shrinkage of blackberry (Rubus spp) in convective – infrared dryer. Experiments were done at three temperature leveles 50, 60, 70 °C with four different pretreatments, including of blanching thermal pretreatment at 70, 80, 90 °C, pulsed pretreatment with microwaves power 90, 180, 360 W, chemical with Ascorbic acid solution at concentration of 1% and mechanical pretreatment with ultrasound in times of 15, 30, 45 min. Results shown that the highest and lowest of Deff</sub></em> value (1.43×10-8</sup> m²/s) and amount (55.52 kWh/kg) was obtained using microwave pretreatment under 360 W power and 70 o</sup>C drying temperature, respectively. Also, the minimum and maximum extent of Deff</sub></em> (4.24×10-9</sup> m²/s) and (239.89 kWh/kg) were in controlled sample and drying temperature of 50 °C, respectively. The highest amount of color difference (30.28) and shrinkage (55.62%) were seen in controlled sample. The lowest value of color difference (7.01) and shrinkage (19.23%) was obtained in microwave pretreatment with power of 360 W and drying temperature of 70 o</sup>C. So, the value of SEC (76.86%), color difference (76.85%) and shrinkage (65.43%) of samples reduced significantly (P<0.05) using various pretreatments, respectively.

In order to investigate the effect of biochar and biological fertilizer on photosynthetic pigments, yield and nutrient content of peppermint (Mentha piperita L.), an experiment was conducted as factorial based on a randomized complete block design in three replications at Sari Agricultural Sciences and Natural Resources University in 2017. Treatment consisted biochar on two level (0 and 10 ton ha-1) and organic and biological fertilizers on five level (no fertilizer (F0), vermicompost (10 ton ha-1) (F1), Pseudomonas fluorescens (F2), Azotobacter (F3) and Arbuscular mycorrhizal (Glomus mosseae, G. intradicces and G. etunicatum) (F4)). The results of this study showed that the main effect of biochar and bio-fertilizer had a significant effect on leaf, stem and total fresh weight of the plant. In addition, the use of biochar and also mycorrhiza treatment increased average of leaf fresh weight (294.73 and 306.8 g.m-2), stem fresh weight (366.73 and 361.15 g.m-2) and total fresh weight (661.46 and 667.95 g.m-2). The interaction effect of treatments had a significant effect on leaf, stem and total dry weight. The highest rate of these traits was observed in biochar treatment with mycorrhiza, which had no significant effect with by a combination of vermicompost + biochar. Therefore, with respect to the production of medicinal plants in the low-input cropping systems, environmental protection, and achievement of sustainable agricultural to improve plant growth and photosynthesis of peppermint application of biochar + mycorrhiz and biochar + vermicompost treatment is recommended.

In ancient Greece, Socrates as Imam of philosophers called himself a philosopher. His goal of rationality was to find the truth and guide the behavior. Aristotle saw the goal of wisdom as pure knowledge and considered it superior to practical wisdom. With the rise of Islam and the emergence of wisdom in the Qur'an, Especially in the era of the translation movement due to the influence of Aristotelian philosophy on Muslim philosophers, this question arose: What is the difference between Qur'anic wisdom and Aristotelian philosophy? Is the practical wisdom of the Qur'an similar to Aristotelian philosophy is inferior? Our hypothesis in this study is the fundamental difference between the two. Therefore, the comparative study revealed that the following are distinct from each other: Qur'anic and philosophical wisdom in the sense of the word and its teachings of wisdom; the problems and goals of wisdom, The trainer and trained of wisdom, the variety of presentations and the ways of acquiring wisdom, the audience of wisdom, and so on are different. It also turned out, although the practical wisdom of the Qur'an is interior in terms relation to credit matters, but in terms insightfulness and gainfulness of theoretical wisdom, the practical wisdom is its criterion, and isn't inferior.

The effects of hot air temperature (40, 50 and 60 oC) and Radiation Intensity (RI) (0.21, 0.31 and 0.41 w/cm2) on the response variables (drying time, Head Parboiled Rice Yield (HPRY), color value and hardness)) of parboiled rice were investigated. The drying was performed using hybrid hot air–infrared drying. The optimization of drying variables and the relationship between response variables and the influence factors were analyzed using response surface methodology (RSM).  Based on RSM results, the best mathematical model for prediction of HPRY, hardness and color value and drying time of samples was linear(R2= 0.96), quadratic(R2= 0.99), linear(R2= 0.93) and linear(R2= 0.99) equation, respectively. The HPRY (62.13- 68.13%) and hardness (130.27- 247.3 N) increased with increasing drying temperature and RI, while the color value (19.77- 18.03) and drying time (59.72- 34.41 min) decreased. The optimized parameters of drying were obtained 55 oC drying temperature and 0.41 w/ cm2 RI.

The aim of this study was to determine the kinetics, effective moisture diffusivity, activation energy, specific energy consumption, and also predict the moisture content of white mulberry during the drying process with microwave-hot air dryer using mathematical models, Artificial Neural Networks (ANN) and Neuro-Fuzzy Inference System (ANFIS). Drying process was accomplished in three temperature levels (40, 55, and 70°C), three inlet air velocity levels (0.5, 1 and 1.5 m/s) and three microwave power levels (270, 450 and 630 W). To estimate the moisture ratio of white mulberry, 10 mathematical models, ANN and ANFIS were used to fit the experimental data of thin-layer drying. The results showed, the maximum and minimum effective moisture diffusivity during drying was calculated 3.56×10-9 and 3.86×10-10 m2/s, respectively. Also, the minimum and maximum effective moisture diffusivity during drying was achieved 48.54 and 1380.88 Mj/kg, respectively. Among the mathematical models under study, the Page model was the best model for describing the behavior of the thin layer of white mulberry drying. The mean square error (MSE) values for the mathematical models, ANN, and ANFIS were 0.00059, 0.0052 and 0.0044, respectively. Therefore, the ANFIS model with the highest Correlation Coefficient (R2=0.99995), the least percentage of mean relative error (ε=1.84) and mean square error (MSE=0.0044) were used to evaluate the moisture ratio in comparison with other methods implemented in this research Selected as the best model

The purpose of this research is to obtain the thermodynamic properties of lemon drying under the influence of ultrasonic pre-treatment in a hot air dryer. Experiments were performed using a convection dryer with ultrasound pretreatment in 40, 55 and 70 °C air temperature, 1 m/s air velocity and duration of ultrasonic pre-treatment of 0 min (for control sample), 10, 20 and 40 min. The drying kinetic of the lemon was estimated by 14 mathematical models. The results showed that the drying time decreased with increasing the air temperature and the time of applying ultrasound. The best model to predict the drying of lemons was selected by Midilli et al. The use of ultrasonic pre-treatment at different temperatures resulted in a significant increase in the effective moisture diffusivity ( ) from 5.04×10-11 to 2.00×10-10 m2/s. Activation energy ( ) of the lemon was obtained between 34.93 and 42.97 kJ/mol. The values of specific energy consumption ( ) were 47.39 to 240.46 kWh/kg.

Eggplant (Solanum melongenaL.) is being cultivated in North America, Asia and the Mediterranean area. Its limited shelf life is one of the important restrictions in the trade of eggplant as a fresh product. Drying is one of the most current methods used to maintenance agricultural products. This process improves the food stability, since it reduces significantly the water and microbiological activity of the material and minimizes physical and chemical changes during its storage. Dynamic modeling of drying characteristics for various agricultural products, including artificial intelligence techniques that include artificial neural networks (ANNs), particle swarm optimization (PSO) and grey wolf optimizer (GWO) Which has attracted a lot of attention recently, because the ability to learn from these systems to detect fruit and vegetable behaviors is a complex process in which mathematical models simply do not apply in recent decades. The main objective of this research was to determine the effective moisture diffusivity, and specific energy consumption of eggplant slices with a semi-industrial continuous band dryer. Moreover, some novel methods including ANN, PSO and GWO as an approximating tools were developed and evaluated for prediction of Deff and SEC of the process. Freshly harvested eggplant were purchased from a local market and stored in the refrigerator at about 4°C for experiments. The initial moisture content of eggplant was determined by oven method. About 40 g of eggplant slice (4 mm thickness) with three replicates were dried at 70°C for 24 h. Eggplant slice with average initial moisture content of 10.25% (d.b.) was chosen as the drying material.
The dryer consists of an adjustable centrifugal blower, hot air suction tube, heater, control panel, air channel to uniform distribution of hot air, drying chamber, Belt (20 cm, 200 cm), three inverters (LS, Korea), temperature and humidity sensors, electrical motor, removable upper part, base, shafts, three infrared lamps (Philips, Belgium) and belt guide. The experiments were performed at air temperatures of 45, 60, and 75C, air velocities of 1, 1.5, and 2 m/s, and belt linear speeds of 2.5, 6.5, and 10.5 mm/s. Feed and cascade forward neural networks were used in this study. There are two types of multilayer perceptron neural network. Two training algorithms including LevenbergMarquardt (LM) and Bayesian regulation (BR) back propagation algorithms were used for updating network weights. The PSO is a simple, powerful and metaheuristic technique that can be applied to solve optimization problems. In the PSO model, every solution is showed as a particle that is alike to a bird flying via the space of a potential solution. In order to mathematically model the social governance of wolves when designing Grey Wolf Optimizer (GWO), assume the fittest solution as the alpha ( ). Consequently, the second and third best solutions are named beta ( ) and delta ( ), respectively. In the present study, the application of Artificial Neural Network (ANN), particle swarm optimization (PSO) and grey wolf optimizer (GWO) for predicting the and was investigated. Based on several statistical operates [such as coefficient of correlation ( ) and mean-square error ( ), mean absolute error ( )], for predicting and was found that the GWO ( =0.9915, =0.9986, Respecively) performs better than the PSO (with =0.9927, =0.9890) and ANN (with = 0.9618, =0.9773) models. Drying behavior of eggplant slices at different air temperatures of 45, 60, and 75C, air velocities of 1, 1.5, and 2 m/s and belt linear speeds of 2.5, 6.5, and 10.5 mm/s was studied. The moisture ratio was reduced exponentially with drying time as expected. When the temperature was increased, the drying time eggplant fruit reduced. In other words, at high temperatures, the transfer of heat and mass was higher and the water loss was more excessive. Effective moisture diffusivity and specific energy consumption were calculated after drying of turnip fruit. Maximum values of for eggplant were 1.14×10-8 m2/s. The lowest amount specific energy consumption ( ) was calculated at the boundary of 130.62 MJ/kg.

Staphylococcus aureus nasal carriage plays an important role in the epidemiology and pathogenesis of infections, and this status accounts for both community-acquired and nosocomial infections..
This study was conducted to determine the frequency of the nasal carriage of S. aureus in healthy medical students..
Patients and This cross-sectional study was undertaken among medical students from August of 2012 until January of 2013. Nasal samples from both anterior nares were obtained from the subjects using sterile moistened swabs, and the isolates were identified as S. aureus by the standard microbiological tests. The antibiotic susceptibility profiles were determined by the disc diffusion method according to the Clinical and Laboratory Standards Institute (CLSI) guidelines..
Out of the 200 nasal swabs obtained, the overall nasal carriage of S. aureus was 24.5% (49/200). The prevalences of the methicillin-susceptible and resistant Staphylococcus aureus nasal carriage were 20% (40/200) and 4.5% (9/200), respectively, while the antibiotic susceptibility tests revealed that all 49 S. aureus isolates were sensitive to mupirocin..
Despite the higher frequency of S. aureus nasal carriage in the interns, compared to the first year students, the difference did not reach statistical significance. Therefore, attendance at medical centers cannot be considered a risk factor for increasing carriage..

The puzzling note is how this metal piece passed through the anterolateral compartment of the thigh to the posterior compartment of the calf. Accord ing to our literature review, migration of fixation pins through the knee joint is an extremely rare occurrence and could be missed by an inattentive physician.

Shiism and Cathilic believe in respectively pure Imam and pure Pope and know the belief as a religious principle lacking it would lead to one`s going out of religion. In spite of such a resemblance, Imam differs in deferent aspects of meaning, place, functions, Imam`s qualities, Imam`s role, its proofs in Quran, tradition and reason, the authority of the proofs as well as the way of Imam`s appointment from Pope. Explaining the structure of the subject and supplemental cases, has sought to describe and study them comparatively and, in this way, prepare a ground for studies in the future.

In the studies between religions, the intercession of punishment and salvation are the common issues in the books of major divine religions. This means that those who commit sin will be forgiven from God punishment by the intercessor. This issue is mentioned in the Jewish Bible, for example in the book of Isaiah (chapters 53, items12), the New Testament, Romans (Chapter 5, item 15), and the Holy Quran, Sura Anbiya (verse 28). The intercession of punishment in the Old Testament is attributed to the mercy of God (Numbers, chapter 14), and in the Quran to His being clement (Zmr / 53 and Anbiya / 107), merciful (Taha /109 and Maryam / 87), and forgiving (Zmr / 53). But the interpretation of intercession, the quality of the intercessor’s practice and its effect (independent or dependent) on the penalties, the relationship between intercession and monotheism, violation of God's will, rudeness of the guilty, divine justice, and the messages of this issue have not been explained well. In this study, different interpretations of the subject and the related issues have been explained from the viewpoints of religions.
