The use of essential oils and new drug delivery systems have been considered two approaches for controlling plant pathogenic fungi. This study aimed to synthesize, characterize, and evaluate the antifungal activity of Solid Lipid Nanoparticles (SLNs) incorporating Mentha×Piperita L. Essential oil (MPE) compared to the free MPE. In the present study, the formulations of SLNs incorporating MPE (MPE-SLNs) were synthesized by high-shear homogenization and ultrasound method, and they were assessed by Z-average diameter, particle size distribution, Zeta potential, leakage stability during 6 months of storage, encapsulation efficacy, and morphological properties of the SLN formulations. The results indicated that the particle size of MPE-SLN formulations was 155.5±4.7 nm with a PDI of 0.156±0.012, a Zeta potential of -15.93±0.87 mV, and encapsulation efficacy of about 88±0.88%. They were physically stable for 6 months of storage. The results also showed that the in vitro minimum inhibition concentration for MPE on the fungal microorganisms, Rhizoctonia solani and Rhizopus stolonifer, were 2,000 and 1,000 ppm, respectively, and for MPE-SLNs it was 1,000 and 750 ppm, respectively. Therefore, the antifungal activity of MPE-SLNs was more significant than MPE, and none of the fungi were susceptible to essential oil-free SLNs. Based on the results, MPE-SLNs can be used for the safe preservation of a wide array of foods and agricultural products.

Saffron is a plant belonging to the lily family, which is one of the most valuable species of medicinal plants and is often cultivated in areas with dry climates. Saffron is the main source of income for many farmers in the rural areas of the east of the country and after pistachio; it is the most valuable agricultural product in Iran. The yield and quality of saffron is influenced by various economic, social, educational and cultural characteristics of saffron growers. Considering the effect of various environmental factors on the growth and performance of saffron, the process of examining the suitability of land for its cultivation requires the use of comprehensive and diverse spatial information. Applying appropriate management methods to solve the existing limitations will lead to the actual performance approaching the potential performance.  Considering that the level of planting saffron in many parts of the country is increasing, and on the other hand, based on the long-term average statistics, its yield has decreased significantly, the need for continuous monitoring of the level of planting and yield is one of the essential issues of managers.  The purpose of this research was to investigate the relationship between climatic and management factors with saffron yield and to determine the most important parameters affecting yield using saffron information in the Kadkan section of Torbet Heydarieh. It was done to analyze and check the performance of saffron in 2021.

In order to investigate the cultivation of saffron and its yield in the Kadkan of Torbat-Hydaria, the data of the cultivation area and yield in 2021 were analyzed. A questionnaire was used to collect data. The questionnaire included information on cultivation area, production rate, and type of irrigation, age of the farm, education and age of the farmer. In this regard, the questionnaire was conducted from 447 people (at the level of 302 hectares) of saffron farmers. The information of these questionnaires was used to analyze the cultivation of saffron in Kadkan of Torbat Heydarieh in 2021.

The saffron yield recorded was 3.8 kg of dry stigmas per hectare, signifying a decrease when compared to previous years, with a decline of 26% and 56% compared to 2019 and 2018, respectively. Analysis of the results revealed that the highest saffron yield was observed in four-year-old farms, amounting to 4.17 kg per hectare. Conversely, fields irrigated from the river exhibited the lowest yield at 2.76 kg per hectare, as per the findings of the current study. Based on this study, there was no significant difference between the yield of saffron stigma in pressure irrigation (4.07 kg/ha) and flood irrigation (4.03 kg/ha) of the researched fields. The yield in saffron farms had an inverse relationship with the age of the farmer, so that with the increase in the age of the farms that were covered by the age of the farmers, the yield decreased and the farms that were under the management of younger people, the yield was higher. According to the results, the saffron farms that were cultivated under the management of uneducated farmers had the lowest yield (2.8 kg/ha) and those with university education had the highest yield of saffron stigma (1.5 kg/ha). The results of the cultivated area data showed that with the increase in the cultivated area of saffron, its yield decreased (the regression coefficient with the first-order model was 26% and the second-order model was 38%).Temperature and rainfall are two influencing factors on saffron performance. In 2016 and 2017, the yield of saffron decreased significantly due to the following reasons: Decrease in rainfall compared to previous years, Improper distribution of rainfall during the vegetative growth period of saffron, The lower and more negative temperatures in 2019 (November, December, December, February and March) compared to the mentioned years caused a decrease in dry stigma harvest in 2014 compared to 2016 and 2018. Given that the majority of saffron farms in the Kadkan district are approximately 4.16 years old (as indicated in Table 2), it is anticipated that the yield of farms in this district may decline in the upcoming year. However, it's important to note that this prediction is solely based on the age of the farms, and actual outcomes may vary depending on climatic conditions. Due to the prevalence of small-scale ownership of saffron farms in Kadkan, managed within a family exploitation system, the management of these smaller farms is typically more manageable. Consequently, it is foreseeable that smaller farms may experience an increase in yield. Therefore, based on these considerations, saffron cultivation is recommended particularly for small-scale owners rather than larger landholders.

Fruits and vegetables are perishable due to high humidity and biological activity after harvesting (breathing, transpiration and biochemical activities). Covering fruits with antimicrobial compounds, while being edible and safe for consumers, is an effective solution to prevent the spoilage of fruits and increase their shelf life. In developing countries, packaging, storage and transportation technologies for these products have not been developed yet. One of the cheap and high-performance methods to increase the shelf life of fruit and maintain its quality during the storage period is to use a coating on the fruit. The purpose of coating application is to reduce water loss, slow aging, polish and better marketing. In addition to improving quality, coating can protect the fruit from pathogens and contamination. Edible coatings create a thin layer on the surface of the food that are effective and eco-friendly alternatives and maintain the firmness of fresh fruits and vegetables. The main components of edible coatings are natural polysaccharides, including starch, cellulose, pectin, alginates and chitosan. These coatings apply by spraying, immersion or rubbing. The use of essential oils and other extracts of medicinal plants has been evaluated in the development of edible coatings.
Adding Ziziphora tenuior L. essential oil to food has been considered as an antioxidant and antimicrobial compound. Directly use of essential oils for fruits and vegetable shelf life has some limitations due to low solubility in water, high vapor pressure and physical and chemical instability. One of the ways to reduce these limitations is the nanoencapsulation of essential oil as. Applications of nano technology to the development of edible coatings (included various nanosystems, including polymeric nanoparticles, nanoemulsions), efforts to control the release of essential oils. Aloe vera gel, which is extracted from the inner parts of the leaves, is clear, odorless, completely healthy and environmentally friendly and can replace the coverings used after harvesting fruits. This is a polysaccharide gel, it dissolves easily in water and has advantages such as preserving the aromatic substances inside the fruit, covering the wound and cuts and it is possible to add substances such as vitamins and essential oils to this gel. Due to the antibacterial properties of aloe vera, adding aloe vera gel to edible coatings can increase the antibacterial properties of this biodegradable coating. On the other hand, using nano technology can increase the efficiency, consistency and better quality of food coatings.
The aim of the present study was to prepare and produce an oral coating of nanoecapsule containing Ziziphora tenuior L. essential oil. The components of the nanocapsule of Aloe vera gel was water, toewin and Ziziphora tenuior L. essential oil. Fresh Aloe vera leaves were used to prepare gel. Zeta-average diameter, particle size distribution, scattering index (PDI) and zeta potential (particle surface charge) were measured. Transmission electron microscopy (TEM) imaging was used to evaluate the morphology of the nanocapsule. The stability of produced nanocapsule was evaluated by measuring the particle size changes for 3 months.
21 compounds were identified in the essential oil of Ziziphora tenuior. The main and important constituents of Ziziphora tenuior L. essential oil were Pulegone, Menthofuran and 1,8-Cineole. The results showed that the particle size of nanocapsule containing essential oil was 84.46 nm and zeta potential was -16.02 mV. The results of transmission electron microscope (TEM) photos showed that the size of the particles is less than 200 nanometers and the shape of the particles is almost spherical. The outer surface of the capsules is completely smooth and uniform. Stability studies of particle size and zeta potential for 3 months showed that nanocapsule containing essential oils had good stability. In this formulation, the zeta potential was about -16 mV, which is due to the non-ionic parts of the surfactant on the surface of the nanocapsule, which contributes to the repulsion force and caused the stability of the size of the nanocapsules. In order to determine the amount of essential oil in the nanocapsule, spectrophotometric method was used. The percentage of essential oil in nanocapsule was 83.25%.
Nanoencapsulation of essential is one of the ways to reduce the limitations of essential oil aplication. In the present study, a nancapsule with natural and biodegradable materials (Aloe vera gel) containing Ziziphora tenuior L. essential oil was prepared and the results showed that Ziziphora tenuior L. essential oil was successfully encapsulated in Aloe vera gel. In general, the results of the present study showed that the nanocapsule of Aloe vera gel is a suitable carrier for Ziziphora tenuior L. essential oil and can be used as an oral coating to preserve fruits and vegetables.

Spiritual intelligence is the ability to act with compassion and knowledge during inner and outer peace, regardless of events and events. People with spiritual intelligence have the ability to be fair in their judgment.

Spiritual intelligence and cognitive bias influence auditors' decision-making style. In this study, the relationship between cognitive bias, spiritual intelligence and ethical decision-making style was investigated. 

The purpose of this study is practical and descriptive - survey data collection and analysis. The statistical population of the auditors working in the audit organization was used, the sampling method is randomly sample and to obtain a sample of the Cochrane unlimited community formula and finally 154 respondents were questionnaires. Structural equation modeling using PLS software was used to test the hypotheses.

  Accounting information affects investor perceptions and judgment, and spiritual intelligence is positively and positively correlated with auditors' decision-making style in the audit organization with coefficients of 0.225 (information-based) and 0.401 (concept-based) at 95% confidence level. The results showed that cognitive bias influenced the relationship between these two variables and had a positive effect.   

The present study showed that cognitive bias influenced the relationship between these two variables, namely spiritual intelligence and decision making, but given the recent financial scandals in the developed countries and consequently those developing countries that violate ethical standards, it is important it has made the auditors' ethical status even more apparent.

Saffron is an annual plant that grows based on underground organs of the plant as corms and can be used for several years under farming conditions. This plant is the main source of income for many farmers in rural areas of eastern Iran. Khorasan Razavi province with 76% of cultivation area and 74% of production has the first place in saffron production. Among the different cities of Khorasan Razavi province, Torbat Heydariyeh city with a cultivation area of about 8 thousand hectares out of 87 thousand hectares of the whole province has an area equivalent to about 10%. Contrary to the level of cultivation, the average yield in Khorasan Razavi province is 3.4 kg / ha, which is 0.22 kg / ha lower than the national average. Considering that the level of saffron that is increasing in many parts of the country and on the other hand, according to the long-term average statistics, its yield has decreased significantly. The need for continuous monitoring of planting level and yield is one of the most issues for managers and programs. This research was conducted using the information of referral letters issued for guaranteed purchase of saffron in the Torbat-e Heydariyeh Kadkan town to analyze and evaluate the performance of saffron in 2017 and 2019.

In order to study saffron cultivation and its yield in the Kadkan town, cultivation data and yield data in the years 2017 and 2019 were analyzed. Guaranteed purchase information of saffron was used to collect data. In 2017, 95 people (at the level of 132 hectares) and in 2019, 173 people (at the level of 257 hectares) of saffron farmers in the Kadkan town to deliver saffron to guaranteed shopping centers (Rural Cooperative Office of Torbat Heydariyeh) to Jihad Agricultural Center. They came to Torbat-e Heydarieh Kadkan and received a letter of introduction. The information of these referrals (area under cultivation, dry stigma yield, production rate, village name and amount of saffron delivered) was used to analyze saffron cultivation in Torbat-e Heydariyeh, Kadkan town in 2017 to 2019.

Based on the results of saffron yield in the Kadkan town in 2017 and 2019, 5.17 and 8.64 kg of dry stigma obtained, respectively. The amount of saffron delivered to shopping centers in 2017 and 2019 was 532 and 1270 kg, respectively. According to the results of saffron yield in 2017 compared to 2019 due to climatic and managerial conditions, has increased by 67%. Fitting of cultivation and yield data of 95 saffron farms in 2017 using a linear model showed that with increasing the area under saffron cultivation, yield decreases R = 0.26 **. Also in the polynomial model. Second degree, with increasing the area under cultivation to the level of five hectares, the yield decreased and since then showed a slight increasing trend (R = 0.26 **). Fitting of cultivation data and yield of 173 saffron farms in 2019 based on the second degree polynomial model R = 0.24 24 ** showed that with increasing the area under cultivation up to seven hectares, the yield has decreased and since then it has an increasing trend. In the third degree polynomial model R = 0.28**, like the second degree of yield, decreased to seven hectares and then increased and then was fixed. Considering that the cultivation area of the most farms in Kadkan town was between 0.1 and 2 hectares and farms up to two hectares in the villages of Kadkan townt, it is non-mechanized, therefore, in these farms, the management of smaller farms could be done more easily and the increase in yield for these farms was predictable.

According to the results of the present study, the yield of saffron in 2017 and 2016 was 5.16 and 8.64 kg / ha, respectively. Considering that the average yield of saffron in the country is 3.62 kg per hectare (Statistics of the Ministry of Jihad Agriculture, 2018), the yield of saffron in the Torbat-e-Heydariyeh Kadkan town can be considered as high yield in the country, which is probably due to climatic conditions and is managerial. 67% increase in yield in 2019 compared to 2017due to climatic reasons (increased rainfall) and management (nutrition, agriculture, training, irrigation, proper planting date, use of corms with appropriate weight, disinfection of corms at planting, Summer irrigation, weed control).

Infection is one of the main causes of delayed wound healing. In addition to infection, in some chronic wounds, such as diabetic wounds, the wound heals slowly due to reduced angiogenesis. For this purpose, a two-layer dressing consisting of gelatin / polycaprolactone nanofibers and polyurethane film can be a suitable solution to accelerate wound healing.

In order to make double-layer polyurethane - gelatin / polycaprolactone nanofiber dressing. Solution of Polyurethane (12%W/v) in tetrahydrofuran / dimethyl formamide is first placed on a magnetic stirrer. After the formation of a uniform solution, the solution is formed on Teflon molds in order to prepare a film by solvent casting. The polycaprolactone / gelatin polymer solution is then prepared at ambient temperature at a concentration of 10% by weight, and finally the fibers are spun randomly onto the fabricated polyurethane film.

The morphology of the bilayer dressing was examined by scanning electron microscopy. Tests such as water absorption, mechanical properties (fracture strain and tensile strength), contact angle and cytotoxicity were performed. The contact angle test for polycaprolactone and polycaprolactone / gelatin nanofibers was measured at 114 and 44 degrees, respectively. Tensile strength for double-layer scaffolding was 4.46 MPa and fracture strain was reported at an average of 330%. Cytotoxicity test showed that the samples were not toxic. Fibroblast cells also showed good adhesion to the dressing.

The results of studies showed that double layer dressing can be a suitable solution for the treatment of diabetic infectious wounds also Skin Tissue Engineering.

Spinacia olerace is the most important leaf vegetable of the Chenopodiacea family, which has a special place in human nutrition because of its variety of minerals and vitamins. Cultivation of this plant in Iran is several thousand years old and accordingly Iran is considered as the main place and a source of spinach in the world. Growth of plants is affected by genetics, environmental conditions, growing season, nutrients, and soil, harvesting method, temperature, intensity and quality of light. Among these factors, soil nutrients have a significant influence on plant growth and yield. Nowadays, the consumption of organic matter as fertilizer due to its high cost and limited availability is not sufficient and the major nutritional needs of plants are met by chemical fertilizers, which can lead to environmental problems and, over time, reduced yields. In this connection humic acid is a naturally occurring organic compound and contains 2% to 5% organic matter. Humic acid can be used to seedling nutrition and improve its quality and quantity. Given the recent use of organic acids such as humic acid to improve crops and horticulture, but little research has been done on transplant birth, this experiment was conducted to investigate the application of different levels of humic acid in irrigation water at the time of irrigation. Different effects and their effects on growth indices and spinach production were investigated.
The present experiment was conducted to investigate the application of different concentrations of humic acid at different times and its effects on quantitative and qualitative indices of spinach in a factorial completely randomized design with three replications in research greenhouse at Torbat Heydariyeh University. Treatments consisted of three concentrations of humic acid (0, 3 and 6 ml/L) at two application times (one-week and two-week). The mean daily greenhouse temperature at the time of plant growth was 25°C and the mean nighttime temperature was 18°C, the average relative humidity was 60%. After seedlings were planted in the main pots at four-leaf stage, they were irrigated with humic acid (0, 3 and 6 ml/L) at different intervals once a week, twice weekly. The humic fertilizer used belonged to Green Seed Company, containing 24% humic acid and 3% folic acid and 2% potassium. Five weeks after treatment, the traits were measured. Transplant growth indices including number of leaves (by counting the number of shoots per plant), leaf length and width, leaf area, canopy, height, chlorophyll index, chlorophyll a, b, carotenoid and dry weight of each plant were determined.
Based on the results of this experiment, the effect of humic acid concentration on morphological and physiological traits of spinach transplant was significant. The highest leaf number (4.6) at 3 ml concentration and the lowest number (3.5) were at zero concentration. These traits were subjected to humic acid titer, but the increase in concentration had no significant effect on these traits. The increased number of leaves and traits mentioned in the early stages of transplant growth is probably due to the rapid expansion of the root system of the plant at high concentrations of humic acid, which in turn leads to increased nutrient uptake, better plant growth and subsequent growth. Leaf number and other traits become leaf dependent. The results showed that the highest chlorophyll a (1.8 ml/g fresh leaf), chlorophyll b (2.5 ml/ml fresh leaf), carotenoids (7.1 ml/ml). Fresh leaf g) and biomass (150 mg) at 3 ml concentration and the lowest at zero concentration. The highest chlorophyll index (74.1 ml/ml fresh leaf g) was also found in the concentration of 6 ml and the lowest was obtained from zero concentration. Humic acid increased spinach transplant biomass by increasing the amount of photosynthetic pigments and leaf area or the same photosynthetic capacity. In most of the traits, the two-week application time was higher than the one-week, so that spinach transplant biomass increased by 110% over the two-week application period. So that spinach transplant biomass was 156 at the two-week application and 74 mg at the one-week application. Based on the results of this experiment, humic acid application can improve the quantitative and qualitative traits of spinach transplant and its production.
Production of vegetable seedlings have an important role in the production and olericulture economy. Specializing in different activities in the vegetable production process will simplify the production process and increase efficiency. This means that the best conditions for seedling growth should be provided during transplanting. Application of humic acid organic fertilizer instead of chemical fertilizer can reduce environmental pollution in line with sustainable agriculture and healthy eating with vegetables to prevent the accumulation of chemicals in the human body to be effective. In this regard, the results of this study showed that using low humic acid as organic fertilizer can improve morphophysiological traits of spinach transplant.

In the present study, multilayer nanocomposites fabricated by accumulative roll bonding (ARB) process. Aluminum sheets, copper sheets (with 0.1 and 0.3mm thickness) and multiwall carbon nanotubes (MWCNTs) were used as experimental materials. The rolling process continued to five cycles. Then, microstructure, hardness, tensile strength and electrical conductivity of nanocomposites were investigated. Necking and fracturing recognized as mechanisms of copper layers distribution in the aluminum matrix. The bonding strength between layers increased with the number of cycles due to the improvement of MWCNTs distribution. The results show that the hardness of aluminum increased with increasing copper layer thickness and these increases were about 30 and 32% for composites without nano reinforcements and nanocomposites contain MWCNTs, respectively. The highest hardness (147HV), is related to the sample containing carbon nanotubes and 0.3mm copper sheet, after five rolling cycles (446% increase compared to aluminum sheets). The results confirm the positive effect of copper and the MWCNTs on the improvement of strength. The highest strength and elongation is observed in the aluminum-copper-MWCNTs nanocomposite after four cycles. The results also indicated that the addition of copper and MWCNTs can simultaneously increase the strength and electrical conductivity of the resulted composites.

Since the discovery of graphene in 2004, two-dimensional (2D) materials have attracted broad interest due to their outstanding electronic and optical properties. In 2014, a new carbon allotrope named penta-graphene ids theoretically was predicted. The advent of penta-graphene inspired various explorations for new pentagonal 2D nanostructures. In this paper, by using the first- principles calculations based on the density functional theory as implemented in Wien2K, Quantum Espresso, and Material Studio codes, a new two- dimensional pentagonal SiGeP2 monolayer is predicted. The structural, kinetic, and thermal stabilities of the newly found monolayer are evaluated and confirmed by cohesive energy computation, phonon dispersion calculation, and first- principles molecular dynamics simulations, respectively. The electronic properties investigations reveal that the predicted monolayer has a strain tunable indirect bandgap of 2.95 calculated by the GGA-PBE level of theory. Through, the presence of a narrow phonon bandgap between acoustic and optical modes suggests its application in electro-mechanical resonators.

Beamforming is one of the most important array signal processing blocks in sonar systems which due to the nature of the environment and conditions of operating, requires using of the robust and adaptive methods to provide the feasible specifications in outputs. In the present paper, the latest methods for the adaptive robust beamforming such as enhanced and modified covariance matrix methods are investigated and finally, by using of simulation in different scenarios and conditions such as steering vector error, sensors gain and phase perturbation and high power noise and strong interference, their capabilities and abilities are presented and method are evaluated. The results show that the methods of Diagonal Loading, LCMV and LCMV mod in different states are not feasible and CMR and ESB methods in the presence of error of steering vector, strong interference and high power noise and gain and phase distortion are more suitable.

In this paper, the new Nano-structure of Germanium disulfide (GeS2</sub>) was forecasted using Wien2k computing software by the method of density functional theory (DFT). The stability of the nanostructure was confirmed by cohesive energy calculation as well as the phonon dispersion calculation. The results of the simulation approach show that‎ the GeS2</sub> monolayer is an indirect band gap semiconductor with a band gap of about 0.9 eV, which is adjustable by a two-dimensional stretching and strain. Besids, the study of the properties of the optics of GeS2</sub> showes that it has minimal absorption and reflection in the visible region of the electromagnetic spectrum, while the GeS2</sub> in the ultraviolet region of the electromagnetic waves is not only a good absorbent but also has a relatively high reflection. The results of this study suggest that the considered structure (GeS2</sub>) has a good application in the new generation of the opto-electronic devices, especially as a UV protection layer.

GMS, is the software that simulate groundwater flow, with using ModFlow based on finite difference method. With comparing the acquired result from GMS and observation data, the existence of error is clear and obvious. One of the methods that decrease simulation error is the usage of filter kalman algorithm. In this study, extended non-linear filter kalman was used in order to improve the simulation results in Birjand unconfined aquifer in southern Khorasan province. The results showed that using this algorithm revealed satisfactory results in prediction of groundwater head. As the mean error (ME), mean absolute error (MAE) and root mean square error (RMSE) are -0.246, 1.125 and 1.341 meter respectively. With influencing extended filter kalman on results these errors decrease to -0.007, 0.015 and 0.019 meter. Also with investigation the results of extended non-linear filter kalman and non-linear filter kalman, it was found extended non-linear filter kalman is better choice for reducing simulation errors.

Evacuation is one of the 6 essential health’s rules. Dysfunction in normal fecal depletion causes multiple diseases. In traditional Persian medicine, constipation is known to be mother of diseases that in addition to the digestive system gradually affects the whole body. Therefore, it’s very important to design proper toilets in order to help proper fecal depletion. The aim of the current study is to investigate the advantages and disadvantages of the two common squatting and sitting toilets.

 This as a review study. Electronic databases such as PubMed, Science Direct, Springer, and Google Scholar were searched using related keywords and related articles in traditional and conventional medicine were studied.

Squatting and sitting toilets are two of the most common toilets. It seems that in healthy people, squatting toilet is the most appropriate choice considering the health of the digestive system, biomechanics and fast, east and complete depletion. Chronic use of sitting toilets has probably lots of adverse effects on the health of the digestive system and consequently the whole body. But if for some reason squatting toilet is not applicable, siting toilet can be considered as a good alternative.

Halitosis is an oral health condition characterized by unpleasant odors emanating constantly from oral cavity. Almost 22-50% of the population experiences such a condition during lifespan and about half of them suffer from personal discomfort and social embarrassment. Based on the literature survey, it seems that the oral cavity is the most important origin of halitosis; therefore, this area could be considered as the best target for the treatment. Halitosis is a well-known disorder in Iranian Traditional Medicine (ITM); Avicenna and some other famous Iranian traditional physicians have described this condition in their manuscripts precisely. Herbal therapy was the major treatment suggested by Iranian scholars in which mixtures of medicinal plants were used in the form of mouthwashes and other oral formulations. In the present study, six Iranian ancient medical texts were screened for the herbs with anti-halitosis effects. Subsequent to this study, the medicinal herbs were listed and scored based on the frequency of their repetition. Moreover, the effort has been taken to provide the best scientific name for each plant as well as searching modern studies about their biological effects. In our investigation fourteen plants were obtained as the most frequent herbs for treatment of halitosis in ITM. Previous studies revealed that some of these plants have shown biological activities relating to anti-halitosis effect. The present study introduces some more plants for future studies about anti-halitosis property.

Medicinal plants have gained more attention due to memory disorders such as Alzheimer and the side effects of synthetic drugs. With regard to the usage of this plant in traditional medicine to enhance memory and as there has not been any research on the effect of Cyperus rotundus (C. rotundus) rhizome extract on learning and memory, this study aimed to assess the efficacy of C. rotundus rhizome extract on learning and memory in male rats.

For this purpose, male rats were randomly divided into a control group (which received solvent) and treatment group. The rhizome extract was administered at doses of 1, 10, and 100 mg/kg for 10 days in the treated group intraperitoneal ly. For evaluating learning and memory, initial (IL) and step-through latencies (STL) were determined at the end of the study using passive avoidance test and alternation behavior percentage was obtained using Y maze.

There was no significant diff-erence in IL, between treated and control groups which mean no change in the ability to learn new information in treated rats. On the other hand, there was a significant difference in STL at dose of 100mg/kg gr-oup compared to the control group (p<0.01). On the Y maze test, alternation percentage showed a significant difference in 10mg/kg group compared to the control (p< 0.001).

Intraperitoneal injection of C. rotundus extract enhances information rec-all. However, its positive effect is more in long-term memory than in short-term memory.

Mentha (Mint) is a genus of flowering plants in the Labiatae (Lamiaceae) family. Mints arearomatic, almost exclusively perennial, and rarely annual. Mint and its medicinal uses havebeen cited in many traditional manuscripts and since Mentha species have different medicalproperties and recognition of these species considering the characteristics mentioned intraditional manuscripts is difficult, we decided to elaborate the corresponding names intraditional medicine and characteristics of 4 native and one hybrid common species ofMentha in Iran including M. spicata, M. longifolia, M. pulegium, M. aquatica and M. ×piperita. The results of this work help the traditional medicine researchers to recognize themedicinal properties specified in traditional manuscripts for each Mentha species.

Personal and social hygiene has been a matter of utmost importance in the Iraniantraditional medicine and even prioritized to the art of treatment of illnesses. Based on sixessential hygienic tenets, regulations were promulgated with the intent of safeguarding the health of individual and society. These six principles comprise the environmentalconditions, nutrition, balanced physical exercise, adequate rest, regular elimination of bodily waste and mental balance are discussed in detail in this article.

Seventy- two 26-weakk-old white leghorn layers (w-36) were fed commercial diets containing 0, 2 and 4 fish oil and the diets were iso-caloric and iso-nitrogenous. Hens were randomly assigned to 3 treatment diets, with 3 replicates and 8 layers in each. The experiment was conducted over a period of 12 weeks in order to study the effects of feeding fish oil on fatty acid composition of egg yolks. The yolk of eggs was extracted and cholesterol content was determined in each period. Statistical analysis of results was performed using the general linear procedure (GLM) of the SAS and means were compared using Duncan’s multiple range test. As a result, saturated fatty acid (myristic, palemitic and stearic acid), ω-7 (palemitoleat) and ω -9 (oleat) and arashidonat in egg yolk was not significantly (P>0.05) different among treatments, but the linoleat and ω -6 fatty acid were decreased in all FO treatments (P<0.05). The linolenic acid did not vary in treatments but the other ω -3 fatty acids (eicosapentaenoate and docosahexaenoate) were increased in FO treatments and there was a statistically significant difference between treatments (P<0.05). The ω -6/ ω -3 ratio was decreased from 18 in control to 3.8 and 2.31 at 2 and 4% treatments, respectively(P<0.05).

Common kilka were chilled during 1, 2, 3, 4 and 5 days to determine the influence of such storage times of fish over the quality of the final canned product. For this propose, common factors for determination of fish quality (moisture, total lipid, free fatty acid, peroxide, thiobarbituric acid and fatty acid profile) were selected and compared with the formation of fluorescence compounds in fish tissue and filling media of canned kilka. In this work common indices showed higher oxidative and hydrolytic rancidity of canned samples compared to raw material but the trend of deterioration with the increase of chilled storage time was not well shown. However, filling media fluorescence compounds was significantly increased with the increase of chilled storage time and the decrease of fish primary quality (P< 0.05). According to the present results, fluorescence detection of interaction compounds can provide a good technique to assess quality differences in the final product as its relates to the quality of the raw material used.

Continuing education is one of the most effective methods to empower the employees for challenges they face on their jobs. Dramatic advances in medicine, rapid cultural and social changes, increasing cost of health care, development of diagnostic technology and a transition in the pattern of diseases, highlight the necessity of continuing education in all medical groups.

To evaluate the effectiveness of continuing medical education (CME) programs in Shahr-Kord Medical Universityfrom 1996-2001.

This cross-sectional study is based on the questionnaires available in Continuing Education Office, which werefilled by the participants in CMEprograms.

In the past five years, 44 CMEprograms were conducted in this university (18planned program programs, 13 seminars, 6 conferences, 5 workshops, and 2 symposiums). Symposiums and workshops were the most appreciated programs. Of 3357participants, 1712 (50.9%)filled the questionnaire. Of these participants, 73% believed that CME programs have strengthened their previous knowledge, 64% noted that the contents of theseprograms were consistent with their job needs and 61% believed that CME programs have encouraged professional self-study. Despite theimprovement of Shahr-Kord Medical University ranking among 8 peer universities, the participants' satisfaction had a declining trend.

Providing up-to-date scientific and practical information and considering adult learning theory, especially performing need assessment before conducting educational programs, will improve the quality of CMEprograms.
