Introduction & Objective: Recognition of climatic variables affecting the thermal comfort and morphology created in the open spaces of residential complexes made it possible to provide appropriate solutions to increase the quality of open environments. Therefore, the purpose of this study is to study the formal geometry and shape structure of residential complexes on the thermal comfort of open spaces to increase the quality of the ambient and the use of users. Methodology: This research is applied in terms of purpose, and the method is quantitative. Four forms of common types of urban residential complexes in Shiraz have been selected with a linear pattern, regular and irregular complexes, central (environmental) and combined (mixed) and have been studied and analyzed in three short cases of 3-storey, medium-height 6-storey and high-rise 12 floors. Methods: To analyze the data, the simulation has been performed by considering the form and orientations in four different patterns in the current situation and by analyzing the results of the simulation with different geometric forms. And their measurement is done using ENVI-met software. Then, using climatic data in Rayman software, the physiologically equivalent temperature is obtained. Findings and Discussion: The results showed that the form of composite and complex blocks in the short case has a better performance in terms of thermal comfort due to more shading. In the mid-height mode, due to the higher wind speed and shading, and the linear form due to the higher wind speed, they have more favorable conditions in terms of thermal comfort and the least critical hours. In the form of composite and complex blocks in the mid-height state, increasing the height reduces the wind movement in other places and the efficiency of these two forms decreases. In the high-height mode, the peripheral and linear blocks have higher wind speeds and more favorable conditions in thermal comfort due to the elongation of the form. Finally, considering the differences in the morphology of residential complexes, it will affect the amount of thermal comfort and utilization of the environment.   Manuscript profile

Inroduction and Objective: Morpholine is a substance with various applications in industry and agriculture which toxic effects can be absorbed into the body by ingestion, by inhalation and through skin. The present study aimed to study of morpholineand physiological saline effect on blood parameters and spleen tissue of6-week-old nmri albino male mice Materials and Methods: 40 adult male mice were placed in 4 experimental groups including control group, physiological saline (sham) group, treatment group A, fed with 300 mg/kg per day for 15 days, 1 ml of the prepared solution (0.009 ml morpholine+ 0.91 ml of distilled water) and group B, treated using the same method with the same volume of morpholine and physiological saline in the same period of time. After weighing, anesthesia and blood sampling, the number of red blood cells, hematocrit and hemoglobin were respectively measured using Neubauer slide, hematocrit capillary tube, and Sally method applying a plasma density refractometer. Microscopic and structural studies were conducted on prepared slides of spleen and statistical analyses were performed using SPSS19 software. Results: Increased number of red blood cells (%6.7), hematocrit (%21), plasma density (%25), and hemoglobin (%10) and decreased thickness of splenic capsule wall and becoming more fibrous (%8.3), increased thickness of central arteriole wall of white pulp (%30), increased spleen weight (%6.14), and reduced body weight (%2.14) were observed in group A, compared to control group and sham group. Considering group B, all listed features (except thickness of splenic capsule wall and weight loss) decreased. The results indicated a significant difference between group A and B (pConclusion: The significance of this relationship indicated that morpholine increased blood parameters, caused parenchyma adhesion, led to inflammation and increased spleen weight and decreased body weight and that physiological saline decreased its adverse effects. Given destructive effects of morpholine and its usage in our daily life, industry should look for a suitable replacement in order to maintain human health. Manuscript profile

In order to investigate the effect of nano-hydroxyapatite phosphate synthesized by two synthetic methods of microwave and ultrasonic on some morphological and physiological properties of maize, an experiment was performed in the factorial form in a completely randomized design in the greenhouse of Kerman Agricultural and Natural Resources Research Center, Summer 2018. Treatments included simple superphosphate and triple superphosphate fertilizer, nano-hydroxyapatite synthesized by microwave and ultrasonic methods, each at five levels in three replications. The results showed that application of nano-hydroxyapatite by ultrasonic method compared with normal condition lead to a 17.47% increase leaf number, 13.02% in stem weight, 46.19 chlorophyll content and 23.06% in phenol content. In addition, nano-hydroxyapatite by microwave method increased the leaf weight, phosphorus and biological yield by 21.87%, 43.47% and 51.06% respectively, compared with control condition. The application of nanohydroxyapatite phosphate improved the growth characteristics and physiology of the maize plant compared to control and simple superphosphate fertilizers and triple. The results also showed that nano-phosphates could more effectively improve the growth and biochemical yield of maize. The highest biochemical function was obtained from nano-hydroxyapatite treatment by microwave method.  According to the obtained results, it is concluded that both methods can improve plant growth conditions and ultimately increase plant yield and production; However, since the microwave synthesis method resulted in higher yield (wet and dry weight), it was identified as the superior method of introduction.

In order to investigate the effect of sowing date on the physiological growth indices of maize, an experiment was performed in the form of randomized complete blocks with three replications in Varamin at 2015 year. The treatments included five sowing dates (9th of April, 21th of May, 18th of June, 30th of June and 15th of July) and the cultivar of Karoun (single cross 701) used. In each of the 5 to 7 day periods of each plot, 5 plants were randomly selected and the traits studied in connection with this study included: total dry weight, leaf area and leaf dry weight to draw the curve of physiological growth indices of maize plants during the growing season. The results showed that the effect of sowing date was significant on the maximum leaf dry weight, total dry weight, leaf area index (LAI), relative growth rate (RGR), crop growth rate (CGR), specific leaf area (SLA) and fresh yield. In the meantime, the fourth sowing date (30th of June) had the highest maximum leaf dry weight, total dry weight, leaf area index, CGR and fresh yield, and the second sowing date (21th of May) was superior to the rest of the sowing dates in terms of maximum RGR and SLA. The CGR was reduced in different sowing dates after reaching its maximum and eventually became negative. According to the results of this study, maize sowing in the first decade of July can be recommended for Varamin region. Manuscript profile

Drought one of the most important global threats against bread wheat production. In order to identify physiological traits associated with drought tolerance, 52 bread wheat varieties were cultured under two normal and drought stress condition in a randomized complete block desigen with three replications. RWC (in three independent times), leaf rolling, leaf silvering, days to flowering, days to maturity and stem reserve remobilization were investigeted. Also in a pot experiment osmotic adjustment of the varieties were measured at seedling stage. varieties Star and Bezostaya had the highest RWC (0.79 and 0.78, respectively). Osmotic adjustment in Rasol and Unknown11 were highest (0.58 and 0.56, respectively). Varieties Tipik, Unknown11 and Azar2 showed the least decrease in thousand grain weight after spraying with KI (4.8, 5.5 and 5.5, respectively). Also varieties Dez, Gaspard and MV-17 have the highest degree of leaf silvering and varieties Niknejad, Star and Kohdasht under drought stress were able than the other varieties bring their leaves to form a rolling and cope with water deficit. Under drought stress, Varieties Alborz, Zagros and Inia were observed premature than the other varieties and Gaspard and Kaslojen varieties were observed late mature than the other varieties. Altogetehr varieties Kohdasht, Star and Bezostaya can be used as genetic resources for leaf water retention under drought stress condition for imjproving other varieties. Also as Azar2 and Unknown11 had highest amount of thousand grain weight under normal condition and simoultanously showed high ability in stem reserves remobilization they can be selected as parents in crosses for improving these traits.  Manuscript profile

Plantain (Platanus orientalis L.)is an important tree used in green space in Tehran. Due to severe air pollution in Tehran, these trees experience early fall in recent years. The present study in an attempt to find the causes of this phenomenon, measured leaf area, dry weight, stomata conductance, stomata resistance, relative leaf humidity, relative chlorophyll concentrations, and the values of calcium, magnesium, lead, and cadmium. Leaves were collected from three regions in Tehran:  Sadra Park  as a clean region, Al-Mahdi Park as the polluted region 1, and Avesta Park as the polluted region 2. Results showed that air pollution causes significant reduction in leaf area and increase in stomatal conductance in Al-Mahdi Park. The highest amounts of magnesium and lead were also observed in Avesta Park plantain leaves. The highest value of cadmium in leaves was recorded in Sadra Park region.  No significant differences were observed in the other traits under study at the collection sites. It seems plantain is able to absorb heavy metals. Manuscript profile

Plum flesh browning is one of the most important disorders in Golestan. This research is aimed to evaluate the effects of climatic conditions on this disorder and other physiochemical traits of the fruit. The evaluation was done using a randomized complete block in a nested design with three replications. The influence of different regions (Azad Shahr, Bandar Gaz, Ghonbad, and AghGhala) on total fruit number, yield, and the percentage of disorder were significant. Results demonstrated that the most fruit number and yield belonged to Bandar Gaz while Azad Shahr had the lowest levels of these attributes. In addition, the highest disorder percentage was registered in Bandar Gaz, whereas no disorder was observed in Ghonbad and Agh Ghala. Data analysis in infected regions (Azad Ahahr and Bandar Gaz) revealed that region had a significant effect on some physical traits of fruits. Furthermore, the effect of type of fruit in region was significant on all chemical traits. Comparison of means showed that the highest fruit length, fruit diameter, stone weight, and stone length belonged to normal fruits of Azad Shahr. The highest soluble solid content was recorded in normal fruits of southwestern Bandar Gaz and the lowest soluble solid content was seen in normal fruits of northwestern Azad Shahr. Physical traits of fruits (weight, length, diameter, and the ratio of length to diameter) showed a significant correlation with physical traits of stone (length, diameter, the ratio of length to diameter, and stone thickness), and the weight of fruit flesh. Among physical traits, fruit weight, fruit length, fruit diameter, stone width, and stone thickness, and among chemical traits only total acidity had a significant relationship with pH.

The aim of this study was to investigate the effect of sesame aqueous extract on growth parameters, proline, chlorophyll pigments, and soluble sugars of leaves and roots of soybean and morning-glory (Ipomoea sp.). To this end, an experiment was conducted as a split plot in a randomized complete block design with three replications in the Research Farm of Golestan Agricultural and Natural Resources Research and Education Center. The main plot included 5 different concentrations of sesame extract (0, 2.5, 5, 10, and 10% with surfactant) and the sub-plot included the target plants at two levels (Soybean and Ipomoea sp). Results showed that the effects of different concentrations of sesame on growth parameters such as root length, fresh and dry weight of shoots and roots, and number of leaves of soybeans and Ipomoea sp were significant different while photosynthetic pigments of these two plants were not influenced by the allelopathic effects of sesame crop extract. Based on the obtained data, increasing the concentration of sesame extract led to increases in the amount of soluble sugars in soybean leaves and roots while decreasing this parameter in Ipomoea sp. Also, the amount of proline in the roots and shoots of soybean and Ipomoea plants increased under effect of sesame extract, in which the increase in the proline content of soybean leaves was significant in comparison with Ipomoea plants. Generally, based on the obtained results, the allelopathic effect of aqueous extract of sesame on morphophysiological parameters of Ipomoea sp. weed in this study was more than those in soybeans, and a complementary research on seed and crop yield, may make it possible to suggest application of sesame extract as a natural herbicide in soybean fields.

Medicinal plants, as important agricultural products, can be considered as the greatest national wealth for any country because of their vital role in promoting national goals for health and also as genetic treasures. Having a diversity of climates, Iran has a great variety of medicinal plants. Detecting the growth status of medicinal plants under drought stress conditions can lead to the cultivation of resistant plants in dry or semidry areas. In the present study, we investigated the morphological and physiological responses of ten ecotypes of the medicinal plant Teucrium polium L. native to southeastern Iran under drought stress. For this purpose, a factorial greenhouse experiment was conducted in a completely randomized design with three replications. In this experiment, moisture treatments of 100, 70, and 40% of field capacity were applied. Analysis of the data showed that the morphological traits under study including stem length and fresh and dry weight of shoots decreased by 5% with increasing drought stress. Drought stress also increased root length, proline content, and phenolic compounds while decreasing chlorophyll a, b, total chlorophyll, and protein contents. The highest resistance to stress was shown by ecotypes growing in Sarcheshmeh and Kuhpayeh regions and the lowest resistance was shown by plants in Shahdad and Anbarabad regions. The results of the study indicated the relative resistance of this plant to drought stress. Therefore, it is a very suitable medicinal plant for cultivation in dry and low water areas of Iran. Among the studied ecotypes, the plants of Sarcheshmeh and Kuhpayeh regions responded 40% better to drought stress conditions and cultivation of these ecotypes in stressed areas can be recommended with more confidence.

The study of use of nutrients and the optimal balance between nutrients and concentrations of absorbable compounds has always attracted the attention of researchers in biological and agricultural sciences. In this research, effects of four levels of Nitrogen sources (100 % urea, nano-chelate nitrogen, 100% Panaromix biologic fertilizer, and 50% urea + 50 % Panaromix biologic fertilizer) along with three levels of Zinc sources (control or without application of Zn, zinc sulfate, and nano-chelate zinc) and interaction effects of hese sources were investigated on physiology and yield of wheat. The study was carried out by split-plot method based on completely randomized blocks design with 3 replications and 12 treatments in a private farm located in the north of Jelin, a city located 3 Km east of Gorgan, during the 2017-2018 crop year. Results showed that the traits under study were affected by the sources of nitrogen supply and the interaction effects of sources of the two elements but there was no significant difference under treatment with sources of zinc supply. In Nitrogen supply sources, the maximum leaf area and number, shoot length, chlorophyll b and chlorophyll (a+b) content, and nitrate reductase activity as well as biological and grain yield was related to 100% urea and 50% urea + 50% biologic fertilizer. In combined treatments with the interaction effects, the highest amount of proline was related to 100% biological fertilizer + nano-chelate zinc and in the treatments that were associated with increased proline, there was no increase in the soluble sugars and glycine betaine contents. The highest level of NR activity, chlorophyll a, and total chlorophyll (a+b) content, and also the highest level of grain performance and biological yield were observed in 100% urea + Zinc sulfate fertilizer treatment. The results showed that high yield of wheat in this treatment was a function of plant physiological behavior, showing a positive interaction between nitrogen and zinc. Manuscript profile

In order to investigate the diversity of 25 populations, an experiment was conducted using 18 morphophysiological characteristics and percentage of essential oil.Samples were collected at their full flowering phase and morphophysiological characteristics were recorded.The results showed a variation among populations. By calculating genetic and environmental variances, changes in most traits including: stem leaf length, stem leaf width and stem leaf width/length, umbellule diameter, umbellule 100 dry weight/ umbellule 100 wet weight and a chlorophyll/b chlorophyll were determined by genetic factors. The general heritability showed the percentage of essential oil, umbellule number in plant and umbellule 100 dry weight were 0.91, 0.51 and 0.77, respectively. Study of correlation between characteristics and stepwise regression exhibited the greatest impact of the flower texture on essential oil production and umbellule 100 dry weight. Based on the factor analysis results, the three main factors justified 78.6% of the total variation among the characteristics. The biomass of the plant was the first factor followed by percentage of essential oil and flower weight as the second and third factors, respectively. Based on the cluster analysis results, the populations can be divided into 5 groups; in which third and fifth groups, with the highest average percentage of essential oil and maximum Umbellule 100 dry weight and Umbellule numbers in a plant, exhibited a great potential for cultivation. Moreover, the populations in cluster 1 and 4 alternatively have the greatest genetic distance from each other which can be exploited in cross over and production of synthetic seeds.

Dracocephalum kotschyi is one of the most important medicinal plants of the Lamiaceae family, which is endangered due to unfavorable environmental conditions. Therefore, in order to evaluate the effectiveness of biofertilizers on changes in some physiological and biochemical traits, the effect of biofertilizers at four levels (nitroxin, super nitroplus, biophosphorus and non-use of biofertilizer) on Dracocephalum kotschyi growth under drought stress at three levels (irrigation until the completion of 80%, 60 and 40% of field capacity), an experiment in 1398 in the form of factorial in a completely randomized design with 3 replications in a greenhouse was carried out. The study of changes in photosynthetic pigments, chlorophyll fluorescence and leaf relative water content in Dracocephalum kotschyi in response to various biofertilizers and different irrigation regimes showed that with increasing drought stress, chlorophyll a, b and total chlorophyll along with chlorophyll fluorescence (Fv/Fm) had a significant decrease. While the use of supernitroplus and biophosphorus biofertilizers in irrigation conditions up to 60 and 40% of field capacity significantly increased the above-mentioned traits in the Dracocephalum kotschyi leaves in comparison with plants treated with nitroxin fertilizer and control plants (Without biofertilizer). Increased drought intensity also caused a significant increase in carbohydrates, soluble proteins, anthocyanins and flavonoids, although the use of biofertilizers containing growth-promoting bacteria, further enhanced the amount of these compounds compared to the control (no fertilizer treatment). The highest levels of anthocyanins (37.82 mg g-1 fresh weight) and flavonoid compounds (16.62 mg g-1 fresh weight) were found in plants grown under severe drought stress (irrigation up to 40% of field capacity) and Biophosphorus application.

Detecting and controlling stress levels in drivers is especially important to reduce the potential risks while driving. Accordingly, in this study, a detection system was presented to identify four levels of stress (low, neutral, high and very high) in drivers based on physiological signals. The proposed method used the drivedb database, which includes the recording of physiological signals from 17 healthy volunteers while driving on specific routes on city streets and highways. A set of statistical and entropy features along with morphological features that were calculated only for the ECG signals, were used. The calculated features were applied as inputs to the classification units to detect stress levels. Support vector machine (SVM), k nearest neighbors (kNN) and decision tree (DT) were evaluated as classification methods. The main purpose of this study was to improve the accuracy of stress level detectionusing the idea of classifiers fusion. To achieve this goal, the combination of individual classification units, each of which used only the features of one of the ECG, EMG and GSR signals, was performed by the Demster-Shafer method. Using genetic algorithm as feature selection method, SVM classifier and Dempster-Shafer fusion strategy, the best stress detection accuracy of 96.9% was obtained. While the highest detection accuracy among individual classifiers was 75% and obtained by a subsystem that used ECG features.The results show significant performance of the proposed method compared to previous studies that used the same dataset.

در بسیاری مناطق ایران شدت نور در طول تابستان میتواند منجر به تنش نوری در گیاهان تحت شرایط گلخانه و هوای آزاد شود. علیرغم اینکه رزها جهت رشد بهینه مکانهای آفتابی را میپسندند، اما در عمل به صورت تجربی مقداری سایهدهی در تولید رزهای گلخانهای در بین کشاورزان منطقه جهت بهبود کیفیت گل تولیدی اعمال میشود. یافتن شدت نوری که ارقام مختلف رز عملکرد و کیفیت مطلوب را تولید کنند بسیار ضروری است. در مطالعه حاضر شدت نورهای مختلف برای دو رقم رز "Red One" و “Gulmira” بوسیله سطوح مختلف سایهدهی 1200، 640، 520 و 240 میکرومول بر مترمربع بر ثانیه بوسیله توریهای پلاستیکی سبز رنگ بکار رفت. نتایج نشان داد که غلظت پروتئین برگ، فعالیت پراکسیداز، مقادیر کربوهیدراتها و غلظت آنتوسیانین گلبرگ به طور معنیداری تحت تأثیر سطوح سایهدهی قرار گرفتند. بالاترین غلظت پروتئین در تیمار شدت نور 640 میکرومول بر مترمربع بر ثانیه بدست آمد. بالاترین غلظت آنتوسیانین گلبرگها در رقم “Red One” و تحت شدت نور 520 میکرومول بر مترمربع بر ثانیه بدست آمد. در رقم “Gulmira” نیز بیشترین مقدار آنتوسیانین در همین شدت نور بدست آمد ولی تفاوت آماری با دیگر تیمارهای سایهدهی نداشتند. بیشترین غلظت کربوهیدراتهای برگ در شدت نور 520 میکرومول بر مترمربع بر ثانیه بدست آمد. نتایج بطور کلی بیانگر آن است که وقتی شدت نور بالاست، سایهدهی تا یک شدت نور حدود 520 میکرومول بر مترمربع بر ثانیه میتواند منجر به بهبود کیفی گل رز شود.  Manuscript profile

In order to evaluation of trend yield and physiological indices variation of some current Rice cultivars an experiment was carried out in split-plot arrangement using randomized complete blocks design with three replication. In 2006 and 2007 years at Shavoor Agricultural Research Station in Khuzestan province. For exposing rice cultivars to different higher temperature regimes, main plots were assigned to three sowing dates from 5 May with 20 days intervals and cultivars namely: Hoveizeh, Hamar (heat tolerance) Ghermez Anbori, Champa (heat sensitive) and Danial (relatively heat tolerant) were randomized in sub-plots. The results of combined analysis of variance showed that the highest grain yield was harvested from the second sowing date (26 May). It was the superior to first sowing date (5May) with 62.5 percentages. The reason of higher yield related to superior physiological indices in panicle exertion, LAD in ripening duration and also higher dry matter storage potential. In among cultivars, Hoveizeh was the superior to other cultivars and had higher yield related to Ghermez Anbori, Champa with 50.9 and 36.3 percentage respectively. In spite of heat sensitive cultivars had higher of Maximum leaf area index but their's crop growth rate, net assimilation rate and relative growth rate were lower. Manuscript profile

In order to study the effects of biological nutrition and irrigation managements on qualitative indices of fenugreek, an experiment was carried out in split plot based on a Randomized Complete Block Design with three replications and 15 treatments at Research Station, Faculty of Agriculture, Azad University, Birjand, Iran, during growing season of 2010-2011. Experimental treatments included irrigation interval (in three levels including irrigation every 6, 9 and 12 days) and biofertilizer (in five levels including nitroxin, biosphere, and micorhyza fungi of G. mosseae, G. intraradices and control treatment or none fertilizer). Results of statistical analysis showed that irrigation treatments had a significant effect on physiological indices like carbohydrate, chlorophyll a, ash, Na, K and proline. The effect of biofertilizer was significant on carbohydrate, chlorophyll a, and on ash. Results showed that proline, carbohydrate, Na, chlorophyll b and ash improved by increasing irrigation interval to every 12 days but K and chlorophyll a decreased. The highest content of carbohydrate, chlorophyll and ashwere observed in G. mosseae, biosphere and G. intraradices, respectively. Overall, results showed that application of biofertilizers had positive effects on qualitative indices of fenugreek and created type of plant adaptation to drought stress. Manuscript profile

In order to evaluate the joint effects of cold and light stresses on chlorophyll fluorescence parameters in stevia (Stevia rebaudiana Bertoni), an experiment was done in a factorial arrangement based on a completely randomized design with three replicates. Treatments were five levels of cold stress (0, 4, 8, 12 and 16 days) at 6±2 ᵒC and three light intensity levels of normal light, 50 and 10 % of normal light (240, 120 and 24 µm.m-2.s-1, respectively). Plants were kept in controlled conditions for 30 days then chlorophyll fluorescence parameters were measured. Results showed that Fv/Fm and Fv/Fo in response to cold stress changed in reduce trend and was described by a segmented model. Accordingly, these parameters increased linearly until twelfth day with a soft slope (0.0007 and 0.0149, respectively) and then decreased with a sharp slope (0.0074 and 0.1098, respectively). Also, Fm, Fv, Ft, Fm' only linearly respond to cold stress when stevia plant grown at 240 and 120 µm.m-2.s-1, while in 24 µm.m-2.s-1 the response of plant was fitted by a segmented model in which linearly decreased and then increased. Furthermore, Y(II) adversely affected by cold stress in all light intensity levels while Y(NPQ) and Y(NO) increased particularly in 240 µm.m-2.s-1. In conclusion, the results suggest that chlorophyll fluorescence parameters are sensitive to cold stress particularly when stevia plant exposed for a prolonged period of time and higher light intensity.

In order to assess the response of ajowan to drought stress that induced by PEG 6000 on germination and growth stages, two separate experiments that in each useed completely randomized design with three replications were done. In first experiment, the response of germination of ajowan seeds was investigated to different levels of drought stress include osmotic potential of zero (control), - 1/5, -2, -2/5 and -3bar that prepared by PEG6000. The second experiment was same first, but in this experiment, morphological and physiological characters of ajowan in different level of drought stress were evaluated. Results of Anova at our data showed that drought stress has significant effect (p≤0/01) on germination characters such as germination percentage, germination rate, height of plumule, length of radicle, dry weight of radicle and plumule. Mean comparison of treatments showed, with increase in drought stress, all the above characters have been reduced. Morphological traits such as leaf area, fresh and dry weight of shoot and root and shoot dry weight ratio to root decreased under drought stress. Also, drought stress had a significant effect on the amount of proline and soluble sugars in the aerial part and root. Comparison of mean of treatments showed that, with increasing stress, the amount of proline and soluble sugars in the shoot and root increased (p≤0/01). The results showed, that germination parameters were reduced by drought stress. Ajowan showed differently responce to tolerate drought stress. Ajowan plant for tolerance to drought stress has different reactions, including reduction of traits such as leaf area and dry and fresh weight of aerial part and root and increase traits such as proline content and soluble sugars.
