Billboards are one of the types of structures that wind load can be the dominant lateral load on this type of structures. Since billboards are usually placed in public places, destroying these structures under wind can cause irreparable damage. In this research, using wind tunnel testing and numerical modeling based on computational fluid dynamics (CFD), the effect of wind on single-plate, two-plate, and triangle billboards has been investigated. The models used in the wind tunnel are made using wood at a scale of 0.01. To find the critical loading pattern of wind load, the structure in the wind tunnel is rotated every 5 degrees concerning the wind direction, and the wind pressure values are recorded. The maximum displacement in single-plate, two-plate, and triangular billboards with tubular column sections is obtained at θ= 45°, θ= 45° and θ= 15°, respectively. Due to the nature of the wind flow, rectangular columns are unsuitable for billboards because the stiffness of the column also changes with the change of the wind angle relative to the billboard.

The Rahmat cultivar (Soy 91-19a line) was developed to introduce an early-maturing soybean cultivar for Golestan province. This cultivar originated from the segregating generations of a crossbreeding program between the Charleston (maternal) and Mustang (paternal) cultivars, initiated in 2001. In preliminary yield trials, the Soy 91-19a line was identified as a top performer, producing 3496 kgha-1. In adaptability trials (2013-2014), using GGE biplot analysis and simultaneous selection for yield and stability, the Soy-91-19a line, with an average grain yield of 2739 kgha-1 and a growth period of 117 days, emerged as the best genotype in terms of yield, stability, and earliness, showing a yield increase of 389 kgha-1 compared to the Williams control cultivar. Under farmer conditions in Golestan, this line produced 3198 kgha-1, demonstrating a 21% yield increase over the Williams cultivar. This line is resistant to Phytophthora sudden death (Phytophthora soja) and semi-sensitive to charcoal rot. Additionally, the Soy 91-19a is indeterminate, multi-branched, early-maturing, drought-tolerant, and resistant to lodging and grain shattering. The oleic acid content of this line is 5% higher than that of common cultivars. Due to its high yield and desirable agronomic traits, this line has been introduced as the Rahmat cultivar for summer cultivation in Golestan province.

Aram is a new oilseed rape cultivar, extracted from the R308 (earlness line) and RGS003 (high-yield cultivar) cross population through pedigree method in three years. To reach high-yielding and compatible lines and cultivars, preliminary and advanced investigations were carried out in Gorgan and Sari (2014-2015) and Zabol, Gorgan, Sari and Borazjan (2016-2017). The line SRL-93-12 (Aram cultivar) with a yield of 2955 kgha-1 and 2774 kgha-1 was the first in the above-mentioned tests, respectively, and the SRL-93-12 line was also recognized as the most stable genotype based on the lowest Lins and Binns superiority index and highest seed yield. Extension research project results on farmers' farms in Behbahan, Moghan, and Gorgan regions showed that the new line with 594 kgha-1 higher yield than the check cultivar was in the first rank. According to the results as well as desirable agronomic traits such as good tolerance to dormancy and uniformity in maturity, this line was released with the name Aram.

Cyclophosphamide (CP) is an immunosuppressive medication which is primarily used to manage and treatt of neoplasms, including breast cancer, lymphoma and Leukemia. CP as well possesses many side effects, including hepatotoxicity which leads to mitochondrial oxidative stress, cell death and hepatic necrosis. Empagliflozin (EMPA) is a Sodium-glucose cotransporter-2 inhibitor used to treat diabetes and has antioxidant activity. The present study was designed to investigate the effect of Empagliflozin on hepatotoxicity induced by cyclophosphamide in male rats.

The present experimental study was conducted at the School of Medicine, Yasuj University of Medical Sciences in 2023. Twenty-four male Wistar rats were divided into four groups: control group, CP group, EMPA+CP group and CP+EMPA group. All groups were treated for 11 days. Moreover, blood samples were obtained and the liver was removed. Plasma levels of ALT, AST and ALP were measured. Homogenized liver tissue was used to measure malondialdehyde (MDA), Nitric Oxide (NO). Liver histology was also performed. The results were analyzed by one- way ANOVA and Tukey's Post Hoc test.

The results indicated that cyclophosphamide triggered a significant increase in the plasma level of AST, ALT enzymes and the level of NO and MDA metabolites in the liver tissue (p<0.001) and increased inflammation, edema, congestion and tissue necrosis compared to the control group. The administration of Empagliflozin led to a decrease in plasma levels of AST and ALT enzymes and tissue levels of NO and MDA and decreased tissue changes compared to the cyclophosphamide group. Furthermore, Empagliflozin reduced histological changes both as prevention and as treatment.

According to the results of the present study, Empagliflozin can reduce the hepatotoxicity of cyclophosphamide probably with reduction of oxidative stress.

Considering the lack of scientific documents published on humans regarding the effect of Stachys lavandulifolia hydroalcoholic extract on abortion in traditional Iranian medicine, the aim of the present study was to determine and investigate the effect of hydroalcoholic extract of mountain tea in combination with misoprostol compared to misoprostol alone in terminating pregnancies less than 12 weeks.

The present randomized clinical trial study was conducted at Imam Sajjad Hospital of Yasuj in 2019-2020 on 40 referring patients divided into two groups. Participants were assigned to two groups of mountain tea extract in combination with misoprostol (group A) or misoprostol alone (group B). In group A, mountain tea in the form of capsules (400 mg every three hours, up to three times, daily) along with 400 micrograms of misoprostol (every three hours, up to three doses, daily) were prescribed. In group B, misoprostol 800 micrograms were taken orally every three hours, up to three doses daily. In case of no abortion, the above dose was repeated on the second day. The intended outcomes included pain intensity, bleeding intensity, patient satisfaction, type of abortion, assessment of side effects (such as vital signs, clinical symptoms, blood parameters, analysis of kidney and liver function indicators). The collected data are analyzed using chi-square and t-test.

There was no statistically significant difference between the two groups in terms of complete abortion (p=0.52) and incomplete abortion (p=52). The duration of intervention in group A (6.10±1.11) was significantly shorter than group B (8.40±0.59) (p>0.001). There was no statistically significant difference between the two groups in terms of pain intensity (p=0.52) and bleeding intensity (p=0.14) at 4-8 hours and 8-12 hours after the intervention. Also, there was no significant difference between the two groups in terms of blood parameters, kidney and liver analysis (p<0.05). In terms of side effects, a statistically significant increase in fever (p=0.008), diarrhea (p<0.001) and nausea (p>0.001) was observed in group B compared to group A. Also, the results of the present study showed that patient satisfaction in group A (6±0) was significantly better than group B (4.60±1.14) (p<0.001).

The findings of this study indicated that S. lavandulifolia hydroalcoholic extract in combination with misoprostol resulted in shorter duration of abortion process, lower adverse outcomes and better patients’ satisfaction compared to the administration of misoprostol alone.

The new oilseed rape cultivar Nilofar (R15), is the result of screening and purifying single plants in segregating generations derived from the cross "Symbol×Orient". During five years of consecutive cultivation, screening of single plants was continued to access pure lines using pedigree method and pure lines were selected in F4 generation. During cropping season 2008-2009, 84 pure lines were evaluated in preliminary yield trial. Results showed that Nilofar variety with a mean yield of 3352 kgha-1 had higher grain yield by 45% compared to the Okapi control variety with a mean grain yield of 1833 kgha-1. In the Value for Cultivation and Use (VCU) trial in six research stations of cold and mid cold regions of Iran including Karaj, Isfahan, Hamedan, Islam abad-e- gharb, Khoy and Arak during two cropping seasons 2009-2011, Nilofar variety with an average grain yield of 3783 kgha-1, ranked first and had 16.1% grain yield more than the Okapi. Under delayed sowing date and stopping irrigation from silique development stage in Karaj during two cropping seasons 2012-2014, Nilofar with 1986 kgha-1 and 0.62 kgm-3 in term of grain yield and water use efficiency, respectively, was superior to Okapi with 1626 kgha-1 grain yield and 0.62 kgm-3 water use efficiency. The glucosinolate content of Nilofar variety was less than 10 μmolg-1 of dry matter and the erucic acid content of the oil was less than 2%. The results of the extension research project in Kermanshah province showed that the mean grain yield of the Nilofer variety at two sites of Sarab Nilofer and Mahidasht was 4004 kgha-1, which was 14.8% higher than the Okapi control cultivar. Due to its high grain yield potential and appropriate agronomic characteristics, line R15 was released under the name of Nilofar and is recommended for cultivation in the cold and mild cold regions of Iran.

The south warm climate of Iran is one of the regions with the ability to grow spring oilseed rape cultivars. Cultivation of oilseed rape in this climate faces the problem of environmental stress such as terminal drought and heat stress. Therefore, in addition to yield, earliness is one of the important priorities to introducing spring oilseed rape cultivars in these areas. Asa (promising line SRL-93-4) is an early-maturing and relatively high-yielding cultivar that resulted from hybridization between R308 early-maturing spring line and Modena as a high-yielding winter cultivar. The segregated generations were conducted by pedigree method. Preliminary and adaptation trails showed that SRL-93-4 line was superior compared to check cultivars in the regions under study. In the adaptation trail, the SRL-93-4 line (with 2581 kgha-1 seed yield) showed a significant superiority over the control cultivar RGS003 (with 2155 kgha-1 seed yield). Also, it was found that the SRL-93-4 line was matured 11 days earlier than the check variety RGS003 on the average. The results of stability methods revealed that SRL-93-4 line was the high stable genotype. A field trial for Blackleg disease showed that the SRL-93-4 line had a relative tolerance to the Blackleg. Analysis of the fatty acids profile showed that SRL-93-4 seed oil had a level of erucic acid close to zero, and in terms of the composition of fatty acids, it was within the standard range, but with more oleic acid and less linolenic acid compared to the RGS003 variety. Also, the amount of glucosinolate of the meal was less than standard level. The results of the on-farm trails in Zahak and Zabol regions of the Sistan and Baluchestan province showed that SRL-93-4 line (with 2200 kgha-1 seed yield) had a non-significant difference seed yield with Dalgan check cultivar (with 2361 kgha-1 seed yield); But it was eight days earlier than the check variety. Therefore, due to the desirable characteristics such as early maturity, relative tolerance to Blackleg disease and good performance, the new promising line SRL-93-4 which released as Asa variety is recommended for cultivation in the south warm regions of the country.

Since 2019, the spread of the coronavirus has caused an epidemic worldwide, and the transmission of the disease through respiratory droplets has been declared as the primary method of transmission in 2020. However, in this study, the indirect transmission of the virus through sewage has been investigated.

Wastewater related to hospital and urban wastewater treatment plants in 5 regions of Ardabil province (northwest of Iran) were investigated. A total of 22 samples were kept in pre-test conditions (temperature -20 degrees Celsius) and were used to identify the viral genome. Specific primer and chain reaction probes targeting ORF1ab and N (nucleoprotein gene) genes were used.

In this research, out of all the samples collected, the result of 3 samples was positive. All three positive samples are related to incoming sewage.

The results of this research showed that sewage epidemiology (WBE) can be considered a cost-effective method for diagnosing and predicting pathogenic agents and an effective method for making decisions to protect citizens' health.

Oak placenta(Jaft) extract has potent antioxidant, anti-proliferative, anti-cancer activity, and other therapeutic properties. Therefore, the aim of this study is to investigate the effect of Jaft extract and its combination with Cisplatin on gastric cancer adenocarcinoma cell line (AGS).

In the present experimental study conducted at Shahid Chamran University of Ahvaz in 2022, the AGS cell line was cultured in 1640-RPMI medium and treated with Jaft extract and cisplatin. Cell viability and combination index(CI) were measured using the MTT assay and Compucyn software(respectively). Moreover, the expression of the CDK2 gene as an important gene involved in the cell cycle was evaluated by Real-Time PCR. The collected data were analyzed using Graph Pad Prism 6 software and one-way ANOVA.

The findings of the present study indicated that Jaft extract and cisplatin cause decreased cell viability of AGS (p< 0.0001). The analysis of compusyn data indicated that these two substances together have synergistic properties (CI<1), in addition to simultaneous usage of Jaft extract increases the cytotoxicity of cisplatin drug. In the simultaneous treatment, it was observed that the expression of CDK2 decreased and led to an increase in the anticancer effect of cisplatin (p<0.001).

The present study revealed that placenta extract had anti-proliferative and anti-cancer properties. According to the synergistic effects of these two drugs, Jaft can change the gene expression of CDK2 in the cell cycle and introduce a possible approach for the treatment of gastric cancer with more potency and less dose of administered cisplatin to induce toxicity. The results of the present study indicated that Jaft extract is a proper selection to sensitize cancer cells to cisplatin.

Considering the importance of pain reduction and recovery of episiotomy and faster return of mothers to daily activities and the lack of existing studies on the effect of the combined gel of Halepah-Aloe vera after episiotomy, therefore the purpose of the present study was to determine and evaluate the effect of Teucrium polium plus Aloe vera gel on episiotomy wound healing, pain intensity and patient’s satisfaction in primiparous women

The present randomized, blinded clinical trial study was conducted on 100 participants in Bandar Abbas Persian Gulf Hospital, Iran. Aloe vera gel combined or placebo gel was prescribed twice in the episiotomy wound site for 10 days in the intervention and control groups, respectively. The outcome variables included pain and wound healing with the Rida scale (the amount of redness, edema, ecchymosis, secretions and the proximity of the edges of the episiotomy wound), patients' satisfaction, and the evaluation of side effects. The collected data were analyzed using chi-square and t-test statistical tests.

The results indicated that the two groups had a statistically significant difference in terms of the Rida score on the fourth and tenth day after delivery (p<0.05). The group of Helepe-Aloe vera combined gel had better wound healing time than placebo. Moreover, in the case of pain, there was a statistically significant lower score in the group of Helpeh-Aloe vera combined gel on the fourth day (5.80±1.34 vs. 6.79±1.42) and the tenth day (1.71±0.88 vs. 91 2.58±0.05) after delivery compared to placebo (p<0.05). The results of the study show that patient satisfaction on the fourth day (3.45±1.17 vs. 5.42±1.37) and the tenth day (1.33±0.57 vs. 2.50±1.21) after Delivery was significantly better compared to placebo (p<0.05).

The findings of this study indicated that the combined gel of Halpa-Aloe Vera improved episiotomy wound, better patient satisfaction and less pain intensity compared to the placebo.

Tall buildings are subject to wind loads as one of the effective lateral loads. An analysis of the effect of wind on Milad Tower is presented in this research. The wind tunnel testing results and numerical modelling implemented in computational fluid dynamics (CFD) using ANSYS software. For the numerical simulation, the K-epsilon model has been used. The study evaluated the flow around the tower in several deformation states and compared it with a model where the tower is modeled rigidly in the wind tunnel. The maximum coefficient of negative pressure (suction) at the top of the tower structure equals to -1.95, which occurs at q =90o, and the maximum coefficient of the positive pressure equals +1. Since the buildings near the tower are located a short distance from the tower, the shed's structure, which is located near the tower, has also been investigated. With the aid of Tecplot software. The wind pressure coefficients obtained from the wind tunnel test were plotted. As part of the wind loading analysis in the single-span and two-span shed models, the model is rotated with a step of 5o relative to the direction of wind application, and wind pressure is recorded.

Supplier selection and determining appropriate replenishment policies is one of the major concerns in production systems and supply chains. This paper describes the supply chain of integrated buyers and suppliers of perishable product. The retailer supplies the product it needs from different manufacturers. Products purchased by manufacturers are perishable products, and their Perishable rate is expressed as a fixed percentage of retailers' and manufacturers' inventories. In this situation, the selection of suppliers and the determination of the quantity to purchase from each supplier have a great impact on the optimization of the supply chain. Based on the fixed demand of the end customers, the retailer tries to determine its optimal replenishment policy, and based on this optimal policy, the process of purchasing raw materials from manufacturers, as well as the time and amount of purchase from each manufacturer will be determined. Among these, the supplier that can deliver the product within the specified time and at the lowest cost will be selected. The main purpose of this paper is to select suppliers and determine replenishment policies in a way that minimizes the total cost of this chain of supply, including retailer and supplier costs. This model uses a mixed-integer linear programming approach. Finally, this model was checked with a numerical example.

In order to evaluation of two new foreign (Greek) upland cotton cultivars Value of Cultivation and Use(VCU) evaluation, during 2018 a trial was conducted as complete randomized blocks design by four replications at three provinces, South Khorasan (Birjand), Fars (Darab), and Ardabil (Moghan). Control common improved commercial upland cotton cultivars were: Varamin and Khordad cultivars (South Khorasan province), Bakhtegan and Golestan cultivars (Fars province) and Varamin and Mehr cultivars (Ardabil province). Based on National Guideline for Testing Value for Cultivation and Use of Cotton, evaluated traits were: 1-seed cotton yield, 2- earliness, 3- boll number per plant, 4- boll weight, 5-lint percent, 6- fibers length, 7-fibers fitness,      8- fibers elasticity, 9-fibers strength and 10- fibers uniformity. Based on trials results, in south Khorasan province (Birjand) new Greek cultivars Maxa and Leon respectively in terms of earliness and fibers uniformity were superior to control cultivars. In Fars province (Darab), control cultivars more early maturity than Maxa and Leon new foreign cultivars. Also, Maxa and Leon new cultivars superior than control cultivars in terms of boll number and Maxa new foreign cultivar regarding to fiber uniformity and elasticity superior than control cultivars. Based on the research results, in Ardabil province (Moghan) Leon new foreign cultivar for seed cotton yield, earliness index and boll weight and Maxa new foreign cultivar in terms of boll number were superior to control cultivars. Also Varamin control cultivar and Leon new foreign cultivars regarding to fibers length were superior to other evaluated cultivars. Therefore, Leon new cotton foreign cultivar cultivation as a new cultivar recommendable in Ardabil province (Moghan).

 Heavy metals such as chromium are among the most common pollutants commonly found in high concentrations in industrial wastewater. They can damage aquatic environments and endanger the health of living organisms, especially humans. This study aims to determine the optimal removal of hexavalent chromium by magnetized activated carbon (AC / Fe3O4) from aqueous solutions.

 The structure and properties of AC/Fe3O4 were investigated by FESEM, FTIR, BET, and VSM techniques. The effect of solution pH parameter (3-11), initial concentration of hexavalent chromium (10-50) mg/L, and adsorbent dose (0.5-2) g/L on hexavalent chromium removal efficiency along with isotherm and kinetics studies was investigated. The concentration of hexavalent chromium was determined by direct reading at 540 nm with a spectrophotometer.

 The optimal conditions for maximum removal of hexavalent chromium at pH=3, contact time of 60 minutes, and adsorbent dose of 1.5 g/L were obtained with an initial concentration of hexavalent chromium of 30 mg/L. The isotherm and kinetics study showed that the experimental data followed the Langmuir and pseudo-second-order kinetics.

 Under desirable conditions, the maximum capacity of AC/Fe3O4 adsorption increased to 21.14 mg/g. The present study illustrated that AC/Fe3O4 could be used as an adsorbent to remove chromium from aqueous solutions.

Slope stability analysis is one of the most important issues in the safe design of infrastructures. This is mainly due to the historical hazards arising from instability of soil mass, leading to serious consequences including both fatality and financial loss. According to the field observations, rainfall is one of the most important factors stimulating the instability of unsaturated slopes. Nonetheless, most classical solution methods ignore the unsaturated conditions by simply assuming the soil conditions to be dry or completely saturated. In order to cope with this limitation, commercial software has been improved for simulation of two-phase flow under unsaturated conditions such as the GeoStudio software package. However, the scientific challenge as one of the limitations of commercial software is the optimization of critical slip surface under transient precipitation. Therefore, the main objective of this research is to develop a homemade computer code in MATLAB based on the Colliding Bodies Optimization (CBO) algorithm so that it can be used for studying complex two-phase flow problems more efficiently in terms of time. The code can effectively calculate and optimize the factor of safety against stability considering the effects of precipitation applied to the slope boundaries by employing Richards’ equation. Calculations of factor of safety are performed by assuming the circular wedge geometry and Bishop's method. According to the algorithm, the centroid of the wedge of slip circles in space is randomly guided and as a result, the coordinates of the circle collision points are obtained within the slope. If the consistency conditions are satisfied, the wedge is divided into parts and the factor of safety is calculated by finite difference method. This process will continue until the optimal factor of safety is obtained. Finally, the results of the code are validated against the output of GeoStudio 2018. The results confirm that the new method is robust in predicting the critical conditions much more rapidly than the software. Although changes in the factor of safety are minor for the simple validation example, the most important feature of the new code is that it reduces the CPU occupancy by 71% on average, independent of the type of CPU.

Increases in tightening the correlation of gas and electricity systems (G&ES), affected by diverse factors, ranging from anthropogenic climate change to the advent of new conversion/generation technologies, have remarkably brought the co-expansion of G&ES using a new concept, the so-called Energy Hub (EH), as well as the potential of storage systems into focus. To assess the effectiveness of EH approach and the role of storage systems in the coordinated plans of G&ES, this paper proposes a comprehensive EH-based planning model for co-expansion of G&ES supply chains with respect to the role of gas storage systems (GSSs). As a mixed-integer linear programming (MILP) problem, the model is applied to a real large-scale case study, i.e. the Iranian G&ES and is solved via GAMS package. The simulation results reveal that incorporation of the interactions existing between G&ES into their planning problems in the framework of an EH can reach more flexible, realistic and optimal expansion plans compared with their traditional integrated expansion planning methods. Furthermore, findings show that the involvement capacities of GSSs provides the opportunity of optimal matching of demand with supply by increasing the productivity of the gas pipelines, allowing technically and economically sensible long-term management of gas supply systems.

Direction-of-arrival (DOA) estimation of audio signals is critical in different areas, including electronic war, sonar, etc. The beamforming methods like Minimum Variance Distortionless Response (MVDR), Delay-and-Sum (DAS), and subspace-based Multiple Signal Classification (MUSIC) are the most known DOA estimation techniques. The mentioned methods have high computational complexity. Hence using the algorithms with high computational complexity in the real-time DOA estimation applications is a serious challenge. On the other hand, the main characteristic of the methods is their high potential for parallelization. The objective of this paper is a parallel implementation of the considered algorithms using a Graphics Processing Unit (GPU) instead of a Central Processing Unit (CPU) for increasing execution speed and real-time implementation of the mentioned algorithms. To this aim, the Kuda programming model is used to implement the algorithm on a GPU. This algorithm is also implemented serially in MATLAB to investigate the parallel implementation performance. The results show that parallel implementation of these algorithms can increase the program execution time ten times more than serial implementation. Accuracies of different implementations are validated using simulations by MATLAB and Kuda.

Commercial quadcopters with many private, commercial, and public sector applications are a rapidly advancing technology. Currently, there is no guarantee to facilitate the safe operation of these devices in the community. Three different automatic commercial quadcopters identification methods are presented in this paper. Among these three techniques, two are based on deep neural networks in which all the feature extraction and classification processes are performed automatically. Deep learning-based methods include the convolutional neural network (CNN), LTSM networks, and a combination of those. The third method is presented using cepstral coefficients and support vector machines. In deep learning-based algorithms, the spectral patterns extracted from the commercial quadcopters' sounds are used as input data. The spectral patterns are obtained by applying the short-time Fourier transform method to the acoustic data. Besides, the cepstral coefficients and the support vector machines are used in the third method to identify and classify the received acoustic signals. The performance of the deep learning and cepstrum coefficients-based methods are compared using the acoustic datasets recorded from the commercial quadcopters. The results show that all three presented methods have adequate performance in identifying the quadcopters. However, the LSTM-CNN method had the best performance by providing an average accuracy of 95.31%, average sensitivity of 96.24%, and average specificity of 95.61%.

Job satisfaction of nurses, as the main body of patient service providers, is of great importance which increases a person's commitment to the job, creativity, efficiency and improves the quality of services. Therefore, the aim of this study was to investigate the relationship between clinical competence and job satisfaction in nurses of Ardabil university of medical sciences.

This cross-sectional descriptive correlational study was performed on 353 nurses of teaching hospitals of Ardabil University of medical sciences. The samples were selected through multi-stage random sampling. Data collection tools included demographic information questionnaire, Minnesota job satisfaction questionnaire and banner clinical competency. Data were analyzed using SPSS 22 software and T-test, Pearson correlation coefficient and regression analysis. Data were analyzed using SPSS-22 software and T-test, Pearson correlation coefficient and regression analysis.

The results of Pearson correlation test showed that there was no significant correlation between clinical competence and job satisfaction (p=0.07). There was a statistically significant relationship between education and guidance and diagnostic practices with job satisfaction among the areas of clinical competence (p=0.001, r=0/88). The results of multiple regression showed that only the domain of diagnostic practices had a significant effect in predicting job satisfaction (p=0.001, r=0/18) and other domains of clinical competence had no significant effect.

The clinical competence and job satisfaction of most nurses were assessed in moderate level. It is necessary for managers to pay more attention to empower and acquire the necessary qualifications of nurses in order to improve the job satisfaction of nurses, which has a direct impact on the quality of nursing care.

A microwave electrothermal thruster (MET thruster) has been constructed, consisting of a microwave plasma chamber 12 cm long and 8 cm in inner diameter and a micronozzle 10 mm long with 1 mm in diameter. The microwave plasma is produced by 2.45 GHz microwave frequency at a power of 1 kW, and the feed gas is Ar at a pressure of 10^-3mTorr. Microwave energy is transmitted into the cavity and electrons sre connected to the wave's electric field. Thus, the electrons are accelerated by microwave electric fields.

One way to manage municipal solid waste and control leachate leaking into the surrounding environment is to bury them inside an isolated compacted clay liner. Despite the low hydraulic conductivity of clay, there is a possibility of fluid flow or chemical species transport. Phenomena that lead to fluid flow are Darcian flow and chemico-osmosis flow which are respectively caused by hydraulic and concentration gradients. On the one hand, membrane behavior of clayey soils causes chemico-osmosis flow. On the other hand, diffusion and advection cause chemical solute to transport. Due to the importance of the subject, this article provides a comprehensive review of the coupled effects of these phenomena with different research approaches. After categorizing analytical approaches into three groups of experimental, theoretical, and numerical and discussing them in detail, the coupled governing differential equations are presented. These equations describe the hydro-chemico-mechanical processes that influence solute transport in landfills. More importantly, key assumptions and findings of selected research with implications for design of contaminant barriers are criticized and discussed. Eventually, a proposal is put forward for future research in this area based on the current shortcomings and research challenges.

Personality traits are one of the effective psychological factors in controlling diabetes. The aim of this study was to determine the relationship between personality traits and confidence in diabetes self-care in elderly with type 2 diabetes.

There was a statistically significant relationship between different dimensions of personality traits and confidence in diabetes self-care (p<0.05). Also, there was a statistically significant relationship between neuroticism with occupation, extraversion with age, as well as flexibility with age and occupation (p<0.05). There was no statistically significant relationship between any of the demographic information such as age, sex, occupation, etc. with confidence self-care.

The results showed a relationship between personality traits and self-care confidence in the elderly with type 2 diabetes. It is suggested that educational programs to be organized for this group of patients in relation to personality traits that can lead to improving the patient's self-care ability and adaptation to the disease.

Soil-water retention curve describes the relationship between soil suction and soil water content. It has a wide range of applications from the predication of unsaturated shear strength to transient two-phase flow and stability analyses. All physically possible sets of retention curves for a soil with specified state parameters are bounded by the two main drying and wetting curves corresponding to the upper and lower bounds, respectively. As a result, the characterization of these two boundary curves as well as the hydraulic hysteresis is of great importance in problems related to both geo-environmental and hydro-geological fields of research. However, direct measurement of the soil-water retention curve requires advanced laboratory equipment and high expertise. In addition, the experimental output has discrete nature and is usually limited to low suction ranges compared with the theoretical full range. In other words, direct incorporation of experimental data to numerical flow and stability analysis becomes impossible; thus, continuous mathematical modeling is inevitable. Consequently, there has always been great interest in the analytical modeling of soil-water retention curves. No thorough study can be found in the literature so far to collect and revisit the pros and cons of various analytical modeling approaches to simulation of this key hydro-mechanical feature. Therefore, the main objective of the current study is to provide a comprehensive review of all available modeling philosophies with emphasis the capabilities and fundamental limitations of each approach. The paper is especially distinctive in classifying all current approaches under seven categories and in providing insights into the general framework of each one. Eventually, a discussion, highlighting the shortcomings and essential modelling needs, is provided to shed light on potential research directions in future.

This investigation was conducted to evaluate the effect of seed pretreatment using silicic acid and sodium nitroprusside on the germination parameters of tomato (Lycopersicom esculentum cv. Isabella) under salinity stress based on a factorial arrangement in a completely randomized design with 5 replications. The first factor, salinity levels, included 0, 25, 50, 100 and 150 mM sodium chloride (0.067, 2.45, 5.44, 9.52 and 14.10 dS m–1, respectively); the second one was the chemical pretreatment of the seed with/without 2.5 mM silicic acid solution (SiA), and the third one was the chemical pretreatment of the seeds with/without 100 mM sodium nitroprusside (SNP). Results showed that, due germination percentage, germination rate, seed vigor index and stress tolerance index were all decreased, but application of SiA and SNP improved some factors in Isabella tomato seed germination. Under saline conditions, the use of SiA and SNP had a significant effect on reducing the effects of salinity in the above-mentioned indices. In general, the negative effects of salinity on the seed germination characteristics could be reduced by pretreating tomato seeds with 100 μM SNP or 2.5 mM SiA solution, alone or in combination, under salinity levels up to 100 mM NaCl (i.e., 9.52 dS m–1).
