        Visible   steam   emitting   from   the   cooling   tower   and   H 2 S   smell   are   obvious   environmental manifestations of a geothermal facility. They are usually coupled with concerns about exposure to the high  toxicity of  mercury  and  arsenic  along  with  radon  radiation. They  have been,  to  a  large  extent, responsible  for  the  perception  that  air  quality  is  significantly  affected  by  geothermal  activities.  In reality, air quality is affected by geothermal facilities a little, especially as compared to many other industries  or  fossil-fuel  power  plants.  If  the  quality  of  air  is  considered  in  the  construction  and utilization of geothermal installations, worries about air quality will be removed. The key to success in air quality programs is the early collection of data, plant operational scenarios, educational programs, etc.The  present  study  aims  at  predicting  dispersion  pattern  of  one  of  the  main  gases  of  Sabalan geothermal power plants to find a solution for its probable negative effects.  Manuscript profile

        Background: Sulfur dioxide as one of the important gas pollutants has an irreparable impact onplants, animals and objects; therefore this monitoring and control is important. Biological indicators asair pollutants indicators, are appropriate conductive in order to air pollution control in urban andindustrial environments. Lichens are one of the bioindicators that are used in this case.Material and methods: Therefore, survey of efficiency and effectiveness biomonitoring of SO2 withuse of lichen, Lecanora mularis, was considered. In this research, Lecanora was placed into the specialbags and exposed with 40, 100 and 200 ppb SO2 for three hours. Then chlorophyll determination (chla, chl b and chl a+b) and ratio of OD 435/415 was measured by extracting of 20 mg net weight oflichen in 10 ml DMSO.Results: Thus, the average of chlorophyll determination (chl a, chl b) in control and exposed samplesto SO2 was 94.1% and 77.3%, respectively; and there was a direct relationship between determinationand pollutant's concentration, in all cases.Conclusion: So, in order to high sensivity of lichens to uptake the SO2, monitoring and indicating theexistence and absence of sulfur dioxide in air is possible, thus this monitoring is one of the mosteffective and applicable approach.

        Parallel with man’s achievements in different aspects of technology, aluminum anodizing industry has improved a lot, but like other progressive industries, it has caused destructive effects on the environment, as well. In fact, aluminum anodizing industry is hazardous because it requires contact with sulfuric acid. The aim of the present study was to control sulfuric acid mist during the process of aluminum anodizing in a factory located in Alborz Industrial Estate. Following sampling, it was found that the concentration of sulfuric acid mists was 8 times higher than the standard level (standard level: 1mg/m3). In order to control the diffusion of sulfuric acid mist in the workshops and the areas where the workers breathe, a local ventilation system, based on the velocity-pressure method and according to the balancing of branches, was put into operation. The implemented hood was chosen based on the standards stated in the American Conference of Governmental Industrial Hygienists (ACGIH) guidelines. And the rate of required standard volumetric flow (scfm) for open-surface tanks was calculated to be equal to 1050 ft3/min for each hood. Consequently, based on the psychometric status of the studied workshop and the actual volumetric flow rate, the rate of required volumetric flow for each hood was considered to be 1239cfm. The whole system was divided into four independent ventilation units, two of which were equipped with 12 hoods (9 with unidirectional suction and 3 with bidirectional suction) and the others with 9 hoods (all with unidirectional suction). In order to resist against corrosion, steel 316 was selected as the constructing material of the canals, and in order to purify the exhaust air, following the necessary evaluations, mist eliminator scrubber system was selected. Also, to provide the required driving force, Back Ward centrifugal fan was considered. Manuscript profile

        In order to identify the best method and time of herbicide application in bromus (Bromus japonicus) control, a factorial experiment was conducted in a form of a randomized complete block design with 3 replications. The experimental treatments include (1) the application of 3 post-emergence herbicides metsulfuron methyl + sulfosulfuron (45 grams of active substance per hectare), (2) sulfosulfuron (26.6 grams of effective substance per hectare) and pinoxaden (450 mg of effective substance per hectare) and (3) three times of herbicide application were before tillering, during tillering and after tillering of wheat. The dry weight of bromus and wheat was measured during all three stages of spraying, 30 and 60 days after spraying and during harvest along with grain yield. Metsulfuron methyl + sulfosulfuron and sulfosulfuron treatments showed the highest reduction in bromus biomass and increase in wheat grain yield both before tillering and during wheat tillering. With the application of herbicides after tillering of wheat, the use of the mentioned herbicides in the control of bromus was observed to decrease in a similar way, and by delaying the spraying time, the yield of wheat was also reduced. Based on the results of this study, two herbicides, methsulfuron methyl + sulfosulfuron and sulfosulfuron, are suggested for the effective control of bromus in the early stages of wheat and weed growth.

        Efficacy of Iminoctadine Tris (Belkute® WP 40%) and Sulphur (Sulfolac® WG 80%) in controlling of cucumber powdery mildew disease agent (Golovinomyces cichoracearum) was studied at 2011-2012 in Karaj under field conditions. Treatments included different doses of Belkute and Sulfolac as the target and Karatane (Dinocap® EC 35%) and Sulphur (Thiovit® WG 80%) as the reference fungicides along with the no spraying control. Trials were done at Complete Randomized Design with 9 treatments and 4 replications. For each plot 10 supposed areas (50×50 Cm) selected randomly and labeled. Foliar application of fungicides were made at the onset of the early symptoms in the treated plots and followed until control plots got high infection at 5, 7, 10 and 14 days intervals. Assessment of the effects of treatments in terms of decreasing disease severity index (DSI) assigned by foliage protection percentage (FPP) was performed using modified Horsfall and Barrat method by giving 1-7 marks, before each spraying. The two final assessing was done with 14 days intervals after the last spraying. Area under the disease progress curve (AUDPC) and efficacy of treatments calculated compared to control using five separate disease assessments data. Analysis of variance done in Randomized Complete Blocks Design (RCBD) for each assessments, AUDPC and efficacy by SAS software, and means were compared with Duncan multiple range tests. The results of analysis of variance revealed that there were significant differences among treatments in DSI in all assessments, AUDPC and efficacy (P<0.05 and P<0.01) for two years. Comparison of the means showed that Belkute 0.75 and 1 kg/ha had the best effects in disease control and decreased disease as 89.46% and 90.74% compared to control respectively. Manuscript profile

        In 2001, an experiment was conducted to evaluate the performance of different herbicides on weed control and yield of ratoon rice in a randomized complete block design with four replications in the Pasha Cola village in Sari, Iran. The treatments were Anilofos + Ethoxysulfuron (3 lit ha-1), Butachlor (3 lit ha-1) + Setoff [Cinosulfuron (100 grams ha-1)], Londox [Bensulfuron methyl (75 g ha-1)] + Butachlor (3 lit ha-1), Butachlor (3 lit ha-1), Cinosulfuron (100 g ha-1), Bensulfuron methyl (75 g ha-1) along with a two-step weeding and weedy treatment (control). Generally, the results showed that the Sulfonylurea herbicides such as Cinosulfuron and Bensulfuron methyl reduced both the density and dry weight of weed and the density and dry weight of weed in total during the growing season. It led to increase in ratoon rice yield at the end of the growing season. In addition, the results showed that the Butachlor did not affect on the density and dry weight of weeds so that it caused a reduction in weight of 1000 grain and yield of ratoon rice.

        In order to evaluate the efficiency of non-chemical and chemical methods and their simultaneous use to control of weeds (Echinochloa Crus-galli, Amaranthus Retroflexus and Convolvulus Arvensis) in maize, a split plot experiment was conducted in the randomized complete block design in three replications and implemented at Varamin-Iran. The main factor (A) was non-chemical treatments consisted of three levels: AM: Irrigation before sowing (agronomic), AC: cultivator (mechanical) and A0 (without agronomic or mechanical operations). Sub-factor was (H) of chemical treatments include three levels of HFS (Foramsulfuron (at a rate of two liters per hectare, HNS (nicosulfuron at a rate of 1.5 liters per hectare), HA + G (atrazine and Gazaprim) and H0 (manual weeding by hand), respectively. The number of Amaranthus Retroflexus and Convolvulus Arvensis weeds (compared to the control) decreased by about 90% with the irrigation before sowing (Am) or cultivator (AC), and the increase in yield (compared to the control) was about 55-60%. While the non-chemical treatments (agro-mechanical) had no effect on reducing the number of Echinochloa Crus-galli weed. Nicosulfuron herbicide, similar to hand weeding (H0), controlled more than 90% of the Amaranthus Retroflexus and Convolvulus Arvensis weeds, but only 70% of the Amaranthus Retroflexus and Convolvulus Arvensis weeds. There was no significant difference in terms of corn grain yield (8000-8500 kg / ha) between hand weeding (H0) and nicosulforn herbicide (HNS) in plots in with agro-mechanical operations. However, in plots where agro-mechanical operations (A0) were not performed, hand weeding (H0) had 12.5% ​​higher corn grain yield compared to Nicosoluren herbicide application (HNS). Therefore, for Echinochloa Crus-galli, a combination of Irrigation-nicosulfuron and cultivator-nicosulfuron treatments is proposed. Manuscript profile

        Sulfur is an organic and mineral in coal and is one of the most disturbing elements in the steel industry.The high percentage of sulfur in Tabas coal is considered as a polluting and harmful element. Sulfur, in addition to reducing the production efficiency of coking plants, causes environmental pollution. The study of reducing the amount of sulfur by physical methods such as flotation is one of the goals of this paper.Investigation of coal samples in flotation method and effective factors in increasing the efficiency of sulfur separation are investigated .Factors such as ash content, the effect of collectors and Foam maker, mechanicalproperties and floating cells conditions are considered.The amount of collector, the amount of foaming and pulp percentage and the remaining time are the parameters that are effective in reducing the sulfur content of the flotation method.By increasing the amount of Gasoil collector, the amount of recycling and the amount of pyrite sulfur decreases with a slow process. Increasing or reducing excessive engine speed reduces the rate of desulfurization. Increasing pulp percentages on reducing sulfur and reducing ash increases recycling rates. Manuscript profile

Results showed that Flawheat biofertilizer had significant effect on leaf area index, plant dry weight, number of fertile spike and seed yied, and application of two liters of biofertilizer improved the traits under study. The highest plant height (117.7 cm) was observed in Tirgan cultivar by using 2 kg.ha-1 of flawheat biofertilizer and 250 kg.ha-1 of sulfur. In all three cultivars of Gonbad, Ehsan and Tirgan, consumption of 2 l.ha-1 of flawheat and 250 kg.ha-1 of sulfur increased wheat dry weight compared to the control. Tirgan cultivar with 5298 kg.ha-1 produced highest seed yield by using two liters of Flawheat and 250 kg of sulfur per hectare. Based on the results obtained, it can be concluded that Tirgan among the three cultivars studied in the central and eastern regions of Mazandaran province, produced higest seed yield by using of 250 kg.ha-1 of sulfur and the application of two liters per hectare of Flawheat.

        This research was conducted in order to evaluate effects of irrigation levels on yield and yield components of 8 pea lines and cultivars at research station of faculty of agriculture in Islamic Azad University, Tabriz branch in 2010 growth season. The experiment was conducted in split plot form based on completely block design with three replications. Treatments were irrigation levels: Irrigation after 70, 105 and 140 mm evaporation from pan as main plot, and lines and cultivars of pea: Jam, Azad, FLIP 00-78C, FLIP 97- 32C, FLIP 00-75C, FLIP 97-26C, ILC8617 and ILC 482 as sub plot. Results showed that the highest branch number per plant, number of pod and number of grain per plant were obtained in ILC 482 and the lowest number grain per plant were obtained in FLIP00-78c and ILC 86 17. The higher values for grain yield (208 g.m-2) were obtained in ILC 482.  In comparison to irrigation after 70 mm evaporation from the evaporation pan, the irrigation after 105 and 140 mm evaporation caused 23 and 45% decreases in the leaf area, 29 and 52% in number of grain per plant, 11 and 23 % in 1000 kernel weight, 29 and 51 % in pod number per plant, respectively. Irrigation after 105 and 140 mm evaporation from the evaporation pan, led to 27 and 64% reduction in grain yield, so in production of pea should be considered to value of water and yield of crop.  Manuscript profile

        Selenium is an essential element for human and animal heath, with antioxidant and anti-cancer properties. Although, researchers have found it to increase vegetative growth. It is not considered to be essential for higher plants. In order to evaluate the effect of selenium and sulfur on growth and yield of three cultivars of spring wheat a factorial experiment based on randomized complete  block design with three replicates was conducted in pots at the Agricultural Faculty of Islamic Azad University, Tabriz Branch, Iran, during 2009-2010. Treatments were 3 cultivars of spring wheat (Karaj, Pishtaz and Sepahan), 5 levels of selenium (0, 0.2, 2, 5 and 10 mg/kg) in the form of sodium selenate used and 4 levels of elemental sulfur (0, 50, 100 and 150 mg/kg). Results showed that 0.2 and 2 mg Se/kg of soil increased growth and yield in all three cultivars, but 5 and 10 mg Se/kg of soil without sulfur, caused toxicity symptoms, white spots on leaf margins, while its toxicity decreased when 50 and 100 mg S/kg of soil was used and toxicity disappeared by using 150 mg S/kg of soil. This indicates that low levels of Se may have positive effects on growth and yield of wheat through meaningful interaction between Se and sulfur. Manuscript profile

        In order to evaluate the effects of integrated weed management on weed control by using reduced herbicide dose, a field experiment was conducted in 2010 in Qazvin. The experiment was conducted in randomized complete block design with 24 treatments and 4 replications. The treatments were: different planting patterns at three levels (single row, square double rows and zigzag double row  plantings) and doses of  Nicosulfuron and Foramsulfuron application at four levels (1, 1/5, 2 and 2/5 liters per hectare), The results showed that among the different planting patterns, zigzag planting reduced weed populations and their dry weights significantly. Foramsulfuron herbicide could control weeds better than Nicosulfuron. Among the herbicide dosages, 2/5 litter dose per hectare highly reduced weed density its dry weight as compared to one litter dose. Manuscript profile

        A field experiment was conducted at Rasht, in 2014, to investigate controlling weeds in native Hashemi cultivar paddy fields by different methods of herbicide applications and inoculated with Azotobacter chroococcum. The factorial experiment based on a randomized complete block design with three replicates was performed. Factors were Azotobacter application with two levels (inoculation with or without Azotobacter chroococcum) and weed management regimes with six levels (pretilachlor plus a supplementary hand weeding, bensulfuron methyl plus a supplementary hand weeding, and pretilachlor + bensulfuron methyl plus a supplementary hand weeding, hand weeding during rice growing period + no herbicide, un-weeded during rice growing period + no herbicide). Results indicated that paddy rice yield was significantly increased by 16% after Azotobacter chroococcum inoculation. Rice paddy yield was significantly reduced in un-weeded plots compared to hand weeded and herbicide treated plots. ANOVA also revealed that there was no interaction effect between Azotobacter chroococcum applications and weed management regimes on paddy and biological yields, indicating that the herbicides had no adverse effect on Azotobacter efficiency in promoting growth and paddy yield of rice. Weed dry weight was reduced by 88, 91, 92, and 94 percentages in weeded plot and plots treated with pretilachlor, bensulfuron methyl, and pretilachlor + bensulfuron methyl, respectively, compared to un-weeded plots. Azotobacter chroococcum inoculation had no significant effect on weed biomass. Overall, the result of this experiment confirmed the feasibility of chemical weed control in paddy fields inoculated with Azotobacter chroococcum. Manuscript profile

        To study the effect of irrigation levels and spraying of chemical fertilizers on some Morphophysiological traits in castor oil plant an experiment was conducted in East Azarbaijan Agricultural Research and Education Center, Tabriz- Iran at the 2017 crop season. The field experiment was carried out by a split-plot design based on a completely randomized block design with three replications. The first factor was irrigation levels consisting of control (normal irrigation), irrigation after 80 mm and 140 mm evaporation from the pan evaporation in asseinged to main plots and eight spraying chemical fertilizers including sulfur, potassium, nitrogen, sulfur + potassium, sulfur + nitrogen, potassium + nitrogen, sulfur + potassium + nitrogen and control to subplots.The results showed that the effects of irrigation levels and chemical fertilizer treatments on all traits were significant furthermore, the interaction of two treatments were also significant on all traits except chlorophyll index. Irrigation interval after 140 mm evaporation reduced the leaf chlorophyll index by 18.25% compared to normal conditions. Also, spraying S + N + K increased this trait by 14.90% compared to the control treatment. The highest plant height (135.15 cm), number of leaves (25.12), stomatal conductance coefficient (276.55 Mmol.m2sec), number of branches (7.25), biomass (1.60 kg.m2) and grain yield (0.45 kg.ha-1) and the lowest proline content (0.19μmol.g-1) were recorded by spraying plants with S + N + K under normal irrigation condition. Spraying plants with S+N +K under irrigation interval after 80 and 140 mm also increase grain yields by 45.83 and 40.0 percent respectively, compared with control treatment and it was able to modify the effect of water deficit on traits under study.

        In order to investigate the effect of nitrogen and sulfur on quantitative and qualitative yield of rapeseed, a factorial experiment was conducted in a randomized complete block design with three replications in Research Field of Shastklateh Forest of Gorgan in 2018. Four amounts of nitrogen fertilizer 25, 50, 75 and 100 kg of pure nitrogen per hectare (from urea source) as the first factor, two amounts of sulfur fertilizer to zero (control) and 200 kg / ha as the second factor and two spring rapeseed genotypes Hyola 50 hybrid and ARGS 003 were selected as the third factor. The results showed that biological yield, grain yield, 1000-grain weight, number of pods per square meter, number of seeds per pod, protein percentage and oil percentage were affected by cultivar, nitrogen and sulfur. Comparison of the average interactions of nitrogen and cultivar showed that biological yield (8360 kg/ha), grain yield (275.6 g/m2), 1000-grain weight (4.1 g), number of pods per square meter (5323.53), Number of seeds per pod (31.64) and grain protein (24.32%), Soluble sugar (33.35 μmol/g) and total chlorophyll (1.38 mg/g) at the level of 100 kg N/ha and Hyola 50 hybrid cultivars and the highest grain oil (41.65%) at the level of 75 kg N and hybrid cultivars Monsters 50 were observed. Also, the comparison of the mean of the interaction of sulfur and cultivar showed that the highest number of latere better ability to absorb and transfer nitrogen and sulfur and therefore produce more yield.

        Plant nutrition from different sources of fertilizers is one of the most critical factors for crop improvement under stress conditions. The purpose of this research was to study the morpho-physiological responses of the lemongrass (Cymbopogon citratus (DC.) Stapf) medicinal plant to the application of different fertilizer sources (control, NPK, nitroxin, mycorrhizal fungi, and biosulfur) under irrigation water salinity stress (0, 100, and 200 mM) in two climates (Fars and Tehran), implemented as a factorial split-plot based on a randomized complete block design in three replications during 2020-2021. Growth and yield attributes and also physiological traits such as photosynthetic pigments, proline content, and qualitative characteristics (essential oil percentage and yield) were measured. Results showed that high salinity concentration (200 mM) negatively affected growth and yield parameters (root dry weight and volume, plant height, number of leaves, and plant yield). The highest plant yield was obtained at 0 and 100 mM salinity with an average of 4183.1 and 4191.9 kg.ha-1, respectively in Fars. Among the fertilizer treatments, there was no difference in terms of plant yield, and all of them led to an increase in yield compared to the control treatment. Using nitroxin biofertilizer under non-stress conditions in Fars region led to the highest total chlorophyll and chlorophyll a, which showed an increase by 51.3% and 47.0%, respectively, compared to the control. Salinity stress (200 mM) and the use of biosulfur in Tehran climate led to an increase in proline content. The use of NPK fertilizer and mycorrhizal fungi under severe salinity stress in Fars led to increases by 2.3 and 2.4 times in essential oil percentage. The lowest average essential oil was also observed in the application of biological and chemical fertilizers in Tehran. The highest essential oil yield was obtained in the application of mycorrhizal fungi under moderate salinity stress in Fars, which was 2.7 times higher compared to the control. All fertilizer treatments at 200 mM level in Fars also had the highest essential oil yield. In general, the lemongrass plant had a good tolerance against the salinity stress of irrigation water and the use of NPK, nitroxin, and mycorrhiza fertilizers while increasing the quantitative and qualitative yield led to the adjustment of the adverse effects caused by the salinity stress.

        This research mainly aims to investigate the effect of economic-social development on air quality in Middle East countries. For this purpose, the effects of Socio-economic Development indicators and natural resource utilization indicators are examined as one of the main drivers of growth and development in the Middle East on Sulfur dioxide  emission as an indicator  for air  quality. Since air pollution is a stable occurrence over time, the time-varying coefficient panel data model during the time period 2000-2019 is used to examine the impact of variables on Sulfur dioxide emissions. The results show that human capital, per capita income, and innovation have the greatest impact on the increase in Sulfur dioxide emissions, but resource usage indicators, especially the consumption of fossil fuels, lead to a decrease in Sulfur dioxide emissions. In fact, given the low use of renewable energy in the Middle East, energy consumption is mainly based on carbon sources. Thus, it is necessary to use environmental technologies and innovations instead of technology-based activities to control this issue in order to achieve sustainable economic growth and development.

        Faujasite zeolites are considered as the main and important component of catalysts of hydrotreating process; In order to zeolites to be achieved higher acidity and volume of mesopores, post-synthetic modification method (dealumination) with different techniques such as: acid treatment (H4EDTA) and thermal (calcination) was used. The dealumination process, while maintaining the crystal lattice of zeolite, led to exit of structural aluminum of zeolite and increase of acidity. NH3-TPD, BET, FESEM, FT-IR, AAS, XRD analyzes were used to investigate the physicochemical properties of zeolite. Atomic adsorption analysis shows an increase in the ratio of silicon to aluminum in the modified zeolite that in the De-Y and De-X zeolites, the Si/ Al ratio increased from 2.27 and 1.2 to 7.8 and 2.2 from the initial values, respectively. Measurement of surface area of zeolite and pore volume were performed by BET and BJH methods; decrease in surface area and increase in mesopore volume in modified zeolites is evident. During the dealumination process, acidity of De-Y zeolite increased from 0.72 mmol NH3 /g to 1.96 mmol NH3 /g and in De-X zeolite, the acidity increased from 0.95 mmol NH3/ g to 0.32 mmol (Na-X). Modified zeolites were used in the synthesis of HDS catalyst. The results showed that the synthesized catalysts had a better performance in removing sulfur compounds and by increasing acidity, the removal of sulfur compounds increased so that Cat-De-Y catalyst has the highest acidity and sulfur removal rate (Conversion= 89%).

        Hydrogen sulfide is a by-product of processes related to fossil fuels (such as natural gas and crude oil). Selective oxidation of hydrogen sulfide process (superclaus) following the claus process used to convert residual hydrogen sulfide to sulfur and plays a major role in controlling and reducing pollutant gases. The catalysts used in this process play a very important role in the production efficiency of elemental sulfur and various materials can be used as catalysts to decrease hydrogen sulfide. These catalysts have specific surface area, porosity, mechanical resistance, particle size distribution, acidity, and other special properties that distinguish them for converting hydrogen sulfide to sulfur. In this study, different types of catalysts that used in the superclaus process are investigated. In this regard, support based catalysts including metal oxides, carbon compounds, zeolites and clays supports as well as supportless catalysts including metal oxides, iron, and vanadium in the selective oxidation of hydrogen sulfide to sulfur are investigated.

        The presence of sulfur compounds in gas condensate is one of the problems in the field of fuel. In this study, the oxidative desulfurization (ODS) process of gas condensate of Ilam refinery was completely studied using molybdenum-based polyoxometalates catalyst. The catalyst was synthesized using a simple method and characterized by FTIR and BET tests. The ODS catalytic activity of gas condensate with total sulfur of 3780 ppm was evaluated in the presence of peroxide hydrogen. The effect of catalyst amount, oxidizing agent amount and operating parameters including temperature, time and type of extraction solvent was investigated on the efficiency of ODS process and solvent effectiveness factor. The results showed that the highest conversion and effectiveness factor were 97.4 % and 8.11, respectively under optimal conditions of catalyst amount of 0.02 wt.% relative to the condensate, the oxidizing agent amount of 6.64 wt.%, temperature of 70 °C and reaction time of 3 h in the presence of dimethylformamide solvent. At this condition, the total sulfur content of the gas condensate reduced from 3780 to 100 ppm. The results showed that the efficiency of ODS process is firstly increased by increasing the temperature and catalyst molar ratio, and then the inverse trend is observed. It was concluded that the reaction time had a positive effect on ODS efficiency. Also, the kinetics and mechanism of ODS reaction were discussed and the mean constant desulfurization rate of ODS was obtained to be 0.022 min-1. Manuscript profile

        Improving safety and increasing efficiency of utilization of natural gas is very important issue due to its wide use as one of the main energy sources for industry and home consumers all around the world. On the other hand, utilization of this clean fossil energy is too risky without considering safety cautions regarding gas leakage, explosion, and flammability. Due to the above mentioned facts and to overcome the problems, it is vital to inject proper compounds to natural gas to make it easily detectable by any person. So far, various types of compounds as "odorant" have been formulated and produced to inject to natural gas. In case of gas leakage, these compounds at low concentration are easily detectable by any person, due to their specific and pungent stink odor. Odorants are classified into classical and modern categories. In this article, a comprehensive study on different aspects of modern natural gas odorants and their odorization process has been performed. In addition, with studying basic chemistry and history of these compounds, the most important properties of odorants have been presented in order to help to recognize the most proper odorant for a specific application and its synthesis methods.

        In this research, desulfurization of diesel from Tehran Refinery was investigated by oxidation method. To investigate this process, the performance of different advanced oxidation systems (acetic acid/hydrogen peroxide, formic acid/hydrogen peroxide) along with acetonitrile extraction were investigated for desulfurization of diesel fuel with 13370 ppm primary sulfur in a discontinuous reactor. The effect of different operating factors such as molar ratio of acid to sulfur (nacid/ns) (15, 20, and 25), molar ratio of hydrogen peroxide (oxidant) to sulfur (no/ns) (5, 10, and 15), temperature and also reaction time were investigated. Many tests showed that in the optimal conditions for removing sulfur from gas oil with the acetic acid/hydrogen peroxide system, the amount of sulfur reached to 9130 ppm with an efficiency of 31%, and with the formic acid/hydrogen peroxide system, the amount of sulfur reached to 2500 ppm with an efficiency of 81%. Also, the examination of the experiments confirmed this point that it is not possible to completely remove the sulfur from heavy oil fractions such as diesel with normal oxidative desulfurization methods.

        Claus process is based on hundreds process of sulfur recovery units in the worldwide because of the shortening sweet hydrocarbons reservoirs and increasing the extraction of oil and gas from sour reservoirs. Suitable selection and predicting the performance of pure alumina Claus catalysts in view of the diversity of manufacturers and the high consumption is an important issue in the efficiency of Claus process. In this paper, catalysts were taken and their physical, chemical, and microstructural properties were evaluated by X-ray diffraction, scanning electron microscope, nitrogen and mercury adsorption, mechanical resistance etc. According to the results obtained from the study of the properties, the presence of active alumina phases and sodium impurity up to 2500 ppm, the lack of boehmite phase and others impurities like silica and iron oxide, good distribution of pore volumes for increasing active surface area and free access to the reaction zone are important properties. These properties lead to a longer life for the catalyst. The high attrition and mechanical resistance with maintaining proper distribution of pore volume and low density are important characters for the catalyst selection. Nanostructured catalysts have suitable properties. Manuscript profile

        Background & Objectives: Chemolithotrophic bacteria have an important role in the biogeochemical cycle in natural ecosystems. For instance, the oxidative part of the sulfur cycle is handled by sulfur-oxidizing bacteria. Moreover, these bacteria have an important role in various industrial fields including bioleaching. The aim of this study was isolation and identification of chemolithotrophic sulfur-oxidizing bacteria from the Namakdan cave Qeshm, Iran. Materials & Methods: In this cross-sectional study, after sampling from the Namakdan cave in Qeshm and transferring the samples (salt, water, and sediment) to the lab, sample inoculation into enrichment media was carried out with three concentrations of NaCl. Following pH and temperature measurement, samples were transferred into solid and two-phase media. Further characterization of the isolates was performed using 16S rRNA gene amplification. Further analysis was performed to characterize the autotrophic or heterotrophic features of the isolates. Biomass was examined using classical turbidity method. Results: Totally, 39 strains were isolated from samples, based on differences in primary features such as colony form or growth rate. A total of 5 isolates were selected for further studies. Phylogenetic analysis showed that these isolates belong to Halothiobacillus genus. Conclusion: Due to 30% salinity and neutral pH of this cave, isolation of chemolithotrophic sulfur-oxidizing bacteria was limited to few genera. Chemolithotrophic bacteria have longer growth time in comparison to heterotrophic ones, increasing generation time to 30 days. Manuscript profile

        In order to study the effect of irrigation interval, humic acid and sulfur fertilizer on some morphological and yield traits of fenugreek, a split-plot factorial experiment based on randomized complete blocks design with three replications was conducted at research field of Islamic Azad University, branch of Birjand in 2013. The main plots were 5 and 10 days irrigation intervals. The sub-plots were combination of two rates of humic acid (0 and 10 L.ha-1) and four types of sulfur fertilizer (control or no application, bentonit containing, humic containing and urea with sulfur cover). In this study plant height, branch number of main stem, pod length, 1000–seed weight, seed yield, biological yield and harvest index of seed were evaluated. The results showed that increasing irrigation interval from 5 to 10 days significantly reduced plant height, pod length, 1000–seed weight, seed yield, biological yield and harvest index of seed by 19.9, 20.9, 34.6, 37.4, 34.4 and 16.7%, respectively. Also humic acid application (10 L/ha) significantly increased all measured traits by 10.3, 13.5, 15.5, 42.8, 47.7, 85.2 and 42%, respectively. The effect of sulfur fertilizer on the measured traits was not significant. Also, interaction of irrigation and humic acid was significant on plant height, 1000–seed weight, biological yield and harvest index. In general 5 days irrigation interval and acid humic application (10 L.ha-1) is recommended for fenugreek cultivation in Birjand. Manuscript profile

        In order to investigate the effects of increasing soluble phosphorus on seed production and phosphorus use efficiency of black seed (Nigella sativa L.) in a calcareous soil, a greenhouse experiment with three replications was conducted at Faculty of Agriculture, Ferdowsi University of Mashhad, Iran, in 2013. A complete randomized design was used based on factorial arrangement. The fertilizer resources (control, vermi compost, sulfur, vermicompost + sulfur, vermicompost + Thiobacilus bacteria, sulfur + Thiobacilus bacteria and vermicompost + sulfur + Thiobacilus bacteria) and three levels of phosphorus (0, 30 and 60 kg.ha-1) were the first and second experimental factors, respectively. Sulfur + Thiobacilus bacteria and vermicompost + sulfur + Thiobacilus bacteria significantly decreased soil pH (by 0.85 and 0.80) and increased EC and available phosphorus of soil (more than 2.5 times), respectively. in condition of no phosphorus application, sulfur or sulfur + Thiobacilus bacteria had significantly effects on increasing the soil available phosphorus. Vermicompost + sulfur + Thiobacilus bacteria had the highest total plant dry weight and seed weight per plant. However, the lowest phosphorus uptake efficiency (15.31%) was observed in control treatment. In a calcareous soil, sulfur application individually or in combination with vermicompost treatment can be suitable approach in decreasing the problems caused by applying of chemical phosphorus fertilizers.

        In order to evolution of radiation use efficiency (RUE) of sesame in the condition of using biological and chemical fertilizers and calculation of light extinction coefficient (K), an experiment was conducted in the year 2013 in RCBD design with 3 replications and 10 treatments. Treatments included biological fertilizers of Nitroxin, Biophosphor, Biosulfur, the mixture of Nitroxin-Biophosphor (Ni+BP), the mixture of Nitroxin-Biophosphor-Biosulfur (Ni+BP+TB) and chemical fertilizers of Urea, Triple superphosphate, the mixture of Urea-Triple superphosphate (U+P), the mixture of Urea-Triple super phosphate-Sulfur (U+P+S) and Control. Results showed that light extinction coefficient of 0.7 was an acceptable value. Biological and chemical fertilizers increased leaf area index (LAI) and RUE of Sesame and generally, chemical fertilizers increased RUE more in comparison of biological fertilizers. The highest value of LAI (3.42 and 3.32) belonged to U+P+S and U+P. RUE values in mixture treatments of biological and chemical fertilizers especially for Ni+BP+TB and U+P+S (1.34 and 1.41 respectively) were greater than its values in the sole application of fertilizers. Urea increased radiation use efficiency of sesame (1.34) more than Nitroxin (1.14), while the amount of increase of radiation use efficiency in triple superphosphate (1.26) and Biophosphor (1.25) was almost identical. Therefore, it is recommended that fertilization of sesame be done by using the mixture of some different biological or chemical fertilizers in order to maximizing RUE by compliment of plant nutritional needs.

The experiment consisted of 10 treatments including separate and combined application of herbicide nicosulfuron, ultima, bromicide MA and 2,4- D by different dose in addition with weedy and weed free during growth season. All of herbicides were effective on broadleaf weed control such as pigweed, lambsquarters and borage. The highest dry weight of weeds was related to weedy treatment, 2-4-D herbicide (1.5 L/ha) and CMA (bromoxynil+MCPA) 1.5 L.ha during growth season. Reduction in herbicide doses of nicosulfuron and ultima (1.5 L/ha and 150 g/ha) were successful in weed control.  While application of Bromicide with 0.5 L/ha besides nicosulfouron 1 L/ha and citogate surfactants did not have proper control of johnson grass. Maximum height, number of kernels per ear, ear length, 1000 grain weight and biological yield were related to non-control. The highest grain yield, was related to weed control treatments than nicosulforun (2 and 1.5 L.ha) ultima 175 and 150 g/ha) and bromicide (0.5 L.ha plus nicosulforun 1.5 Lha). Grain yield reduction was 45 percent in control treatment compared to control weeds. Reduction of grain yield was also 27 and 37% with 2-4-D and Bromicide respectively, compared to control weeds.   Manuscript profile

PEG/Salpn complex with weight ratio 1:4, 2:4 and 3:4 of Salpn and PEG were prepared in methylene chloride solvent by a simple deporotonation procedure. Obtained Results show that PEG/IMZ complex is very effective corrosion inhibitor of carbon steel in the acid environment in compare with PEG, Salpn and noncomplex form of them. Maximum corrosion inhibition was obtained for PEG/Salpn complex with weight ratio 1:4 of Salpn and PEG. The inhibition efficiency increased with the increase in the temperature up to 45°C and decrease in higher temperatures. Results from all the corrosion tests were examined using SEM and are in reasonable good agreement. Adsorption thermodynamic data (〖K 〗_ads and 〖∆G〗_ads ) was calculated using the weight loss data Manuscript profile

        In this research, the tanks made of carbon steel, similar to the practical conditions and in the form of pilot, was investigated. The tank containing 98% and 72% sulfuric acid was evaluated by potentiodynamic polarization test, open circuit potentials and potentiostatic test. Also, electrochemical noise measurement was carried out before, during and after the anodic protection, and the results were analyzed by statistical analysis at time intervals. . By analyzing the frequency range, PSD curves were obtained and it was observed that the values of slope and current and potential skewness could be used to determine the deviation or non-deviation of the normal distribution of electrochemical noise data. It was also found that by using spectral density curves, it is possible to eliminate the negative effects of additional noise and obtain complete information about the corrosion process. Noise resistance was obtained, but the noise resistance could be applied qualitatively to determine the corrosion rate. In this study, it was concluded that the electrochemical noise method is an efficient method for studying corrosion phenomena, such as crevice corrosion and anodic protection system during protection of tanks and heat exchangers in sulfuric acid. It was found that for a mild steel tank in Sulfuric Acid 98%, during protection, the slope value of the ROLL-OFF region was 2.4 and for dilute sulfuric acid 4.4, and it was found that in this area, the anodic protection was considerably high for carbon steel so protection in the sulfuric acid solution 72% is more suitable.

        Mustard sulfur (SM) is a blister and has destructive effects on the lungs, eyes, and skin. MicroRNAs are non-coding RNA molecules that regulate many important cellular pathways. The clear association of microRNA expression changes in a wide range of diseases and their interception in various organs of the body, including the skin, has made them a suitable biomarker. This study aims at evaluating the changes in miR-21 gene expression in chemical warfare victims infected with SM. In this study, skin biopsy specimens including 10 veterans exposed to SM with moderate complications, 10 veterans exposed to SM with severe complications, and 10 control samples were collected, and then total RNA was extracted. cDNA synthesis was performed. MiR-21 gene expression was assessed using real-time PCR. 5 s rRNA gene was used as the internal control. Graph Pad Prism software version 6.07 was used for the statistical analysis of data. Roc curve was used to evaluate the biomarker value of the miR-21 gene. Increased expression of the miR-21 gene was observed in samples of SM veterans compared with normal samples. There was a statistically significant difference in the expression of the miR-21 gene in the skin samples of veterans exposed to SM with moderate complications and veterans exposed to SM with severe complications compared with the samples of control skin (P-value 0.0001). The expression of the miR-21 gene in the skin samples of veterans exposed to SM with severe complications and veterans exposed to SM with moderate complications in old age was not significantly related to the control sample (P-value = 0.8049, P-value = 0.3802). This study showed that the relative expression of miR-21 could be a potential biomarker in distinguishing SM veterans from healthy individuals but needs further researches.. Manuscript profile

        This experiment was conducted in order to investigate the effect of zinc foliar application and different levels of sulfur fertilizer on yield and wheat yield components of Baharan cultivar in 2016-2017 in Tehran Agricultural and Natural Resource Research Center. The statistical format of the design was factorial based on random complete blocks in 3 replications. The factors include sulfur fertilizer at three levels (zero, 250 and 500 kg.ha-1 from biosulfur or thiobacillus sulfur) and zinc element foliar application of zinc sulfate source (ZnSo4, 2H2o) at three levels (pure water spraying, solution Zinc spraying with a concentration of 0.5% and 1%). Zinc sulfate contained 34% pure zinc. The results showed that sulfur consumption had a significant effect on yield and quantitative components of wheat growth. The effect of consumption of this element on gluten, protein and grain content was also significant. Foliar application of zinc also had a significant effect on the weight characteristics of one thousand seeds, number of fertile tillers, grain yield, biological yield and leaf surface index. Also, all the qualitative traits of the grain were significantly affected by this element. The highest grain yield was obtained from the treatment of 500 kg of sulfur with 1% solution of zinc spraying at 6789 kg.ha-1. The combined use of biofuels and zinc increased the yield of wheat grains by 36%. The highest weight of 1000 grains was obtained from the consumption of 500 kg.ha-1 of sulfur and zinc foliar application with a concentration of 1% and a rate of 49.6 g. The maximum gluten in the grain was obtained from the consumption of 500 kg.ha-1 of sulfur and zinc foliar application with a concentration of 1%, respectively. Under the conditions of sulfur consumption, the positive effect of zinc foliar application on this trait increased. Zinc consumption increased the protein content by 10.3% and 17.7% for two concentrations of 0.5% and 1% of foliar application, respectively. The highest percentage of protein was obtained in the treatment of 500 kg.ha-1 of biofuels. The highest amount of zinc was recorded in the treatment of sulfur consumption of 500 kg.ha-1 along with 1% solution of zinc spraying at a rate of 63.30 mg.kg-1. The increase in leaf area index for both sulfur and zinc was significant compared to control.       Manuscript profile

        Cycas revolute is one of the most primitive living seed plants of subtropical landscapes. There is substantial demand for ornamental leaf trade due to their attractive shape and long shelf life. Seeds of most commonly cultivated Cycas species is now available. Fast and uniform seed germination is essential because of relatively rapid loss of seed viability of Cycas duo to delayed seed germination. Some dormancy mechanisms contribute to delayed seed germination including: inhibitors, thick and very hard sclerotesta, and immature embryo at the time of seed abscission. An experiment was conducted as a factorial in compeletely randomized design in order to study the effect of growth regulators and temperature storage on embryo development and germination of Cycas seeds. Seeds were stored at 5 and 22˚C for 24 weeks and subsequently were treated with H2SO4 (15M) for 0, 15, 30 and 45 minutes followed by 100 and 200 ppm of GA3 for 0, 24,48 and 72 hours. Seeds then were planted in trays filled with coarse and were placed in greenhouse with 28 /20˚C (day/night) under mist system. The results indicated that 92 % of seeds survived at 5˚C, but only 42% of stored seeds at 22˚C were alive after 24 weeks. Gibberellic acid and Sulfuric acid treatments had showed considerable effect on seed germination and their higher concentrations and longer exposure time increased germination rate and speed. Seed treatment with 200 mg/lit. Gibberellic acid for 48 hours and Sulfuric acid (15 M) for 30 minutes resulted in optimal germination rate of stored seeds at 5˚C for 24 weeks. Manuscript profile

        Alkalinity of soils in many cultivated areas of corn in Iran prevents the accessability of nutrients, particularly phosphore (P), by the plant. Application of solphur (S) and its subsequent oxidation which is usually accompayning with a reduction of soil PH will enhance the absorbability of P and most micronutrient solubles in the soil. Today, low price of phosphorus sources such as apatite and composts can be taken into consideration as phosphorus fertilizers for plant nutrients in agriculture. These sources could promote absorbable phosphors in the alkaline soils and later on taken by the plant. However, we studied effects of changing PH and increasing phosphorus solubles in the soil on yield production of a corn single cross 301. The experiment was a factorial based on a  randomized complete block design with three replications and carried out at the Research Station of Soil and Water Research Institute, Karaj, Iran, in 2005. The experiment consisted of four factors, each at two levels such as: urban compost (0 and 10 t/ha), Phosphate-solubilizing microorganisms (PSB) as check and bacteria, apatite (0 and 1 t/ha) and phosphor (P) inoculated with oxidative Thiobacillus bacteria (0 and 4 t/ha).. The results showed that the highest yield (9600 kg/ha) was obtaind for the application of compost and Bacillus megaterium treatment. For the factors in which only apatites was used, yielded the lowest value (6937 kg/ha) as compared to the check (7700 kg/ha). Indeed, interaction effects of compost and Bacillus megaterium was significant (P <0.05) for yield. Application of apatite in alkality soils not only did not increase phosphorus solubles, but had a negative effect on the soil characteristics and plant growth. It is suggested that application of compost and Bacillus megaterium promote the accessability of plant to nutrients like phosphor and consequently will increase yield production of corn in the field.

        Effects of different amounts of four nitrogen fertilizers sources on seed and oil yield of rapeseed cv. SLM046, and nitrogen residues in the soil were studied after harvesting. An experiment was conducted at Zanjan Agricultural Research Center, in 2004. A factorial experiment based on a randomized complete block design with three replications was used. Five levels of N comprised of 0, 60, 120, 180 and 240 Kg of net nitrogen/ha and fertilizer sources of sulfur coated urea (SCU), urea (U), ammonium nitrate (AN), and ammonium sulphate (AS) were used at three stages: planting time, stem elongation and seed setting, but U fertilizer was applied at the planting time. The highest seed and oil yield were obtained for UN240. The highest N residues were found for SCU fertilizer. An increase of nitrogen (N) ranges from 0 to 240 kg/ha incraesed N residues in the soil. In addition, more NO3- was observed by applying AN, U, and SCU as compared with SA. The highest and the least NH4+ in soil was detected when fertilizers SCU and AN were applied, respectively. In general, despite of different N applications in rapeseed, amounts of NO3- and NH4+ residues in soil were lower than of those before planting, indicating high potential of rapeseed crop in N absorption. It was also revealed that increase of applied N was in contradictory with nitrogen uptake efficiency. NA fertilizers showed the highest and SCU the lowest nitrogen uptake efficiency in rape seed crop. Manuscript profile

SC704 in different growth stages an experiment was conducted in factorial based on randomized complete block design with three replications at the Research Station of Saatlo, Urmia, north-western Iran during growing seasons of 2013-2014. Treatments were five levels of foliar application include (N (Urea), Mg (MgSO4.H2O), Fe (FeSO4.H2O), Sulfur WP, and control) and three growth stages including of the 8-10 leaves stage, the tasseling stage and the seed-filling stage. Concentrations of foliar applications were determined in ratios of 5 to 1000 for Mg, Fe and S and 5 to 100 for N. A significant effect of different growth stages on ear height, number of row on ear, number of seed on row, 100-grain weight and total seed weight was found. Also, nutrients foliar application had a significant effect on ear height, number of seed on row, 100-grain weight and total seed weigh. In all of traits, treatment of 8-10 leaves stage had the highest and nitrogen foliar application in all treatments but seed on row number had the highest value. Application of treatments on 8-10 leaves stage was more than filling stage had 42.46% ear height, 5.98% number row per ear, 45% number of seed per row, 39.42% 100-grain weight and 2.84% total seed weight on ear. N-foliar application increased 45.71% ear height, 29.1 % 100- grain weight and 33.61 % total seed weight on ear compared to control. Besides, Fe foliar application had the highest number of seed on row comparing to control (43.39%). On the whole, 5% N foliar application and 5/1000 Fe foliar application improved the some of morpho-physiological characteristics of maize. This indicates that spraying while also providing balanced nutrition, is also economically affordable. Manuscript profile

        The experiment was carried out as a factorial experiment based on a randomized complete block design with four replications to evaluate of the best combination of herbicides and cultivation in silage corn fields in Miyaneh region in the summer of 2009. Treatments were cultivation (with or without it), herbicides (Foramsulfuron, Nicosulfuron and 2,4-D+MCPA) and hand weeding. Weeds were sampled in three stages during growing season after treatment applications and weed density and weed dry weight were recorded. The results indicated that herbicide treatments were significantly influenced in weeds density and dry weight at 1% probability level. The most effective herbicide for weeds density and weeds dry weight decreasing percentage was Foramsulfuron which was significantly different from other herbicides. The lowest weed density and weed dry weight were observed in 2,4-D+MCPA treatment. Cultivation was significantly effective on weeds density and weed dry weight. Therefore, chemical control along with cultivation could result in weeds depression and crop yield enhancement. Manuscript profile

Based on the results, treatment Titus (recommended dose) in terms of bindweed and amaranth in the highest group were statistically numerically, although it has a dry weight of less than weed density was reduced doses according to the comparison showed that the average yield of herbicide Epirus recommended dose (57/27 tons per hectare) no significant difference in weed control though numerically less than it was, among herbicide treatments reduced dose of Snkur + Epirus (75% of the recommended dose), Snkur + Epirus (50% dose recommended) and Snkur + Titus (50% of the recommended dose) produced, respectively, 52/24, 35/24 and 10/24 tons per hectare in the same statistical that would have been acceptable performance and herbicide Titus 75% of the recommended dose produced a numerically 60/15 tons per hectare is the lowest yield.
