Aim: Spiritual well-being is one of the most important aspects of health that provides the integration and coordination of all aspects. However, due to the increasing number of the elderly, it is important to pay more attention to their health. This study was conducted to determine the spiritual well-being of the elderly residents of Zahedan in 2016.
Methods: This cross-sectional study was conducted on 117 elderly people residing in Zahedan. They were selected through population-based cluster random sampling to participate in the study. In order to measure spiritual well-being and evaluate its relationship with demographic variables we made use of Paloutzian and Ellison’s spiritual well-being questionnaire. Moreover, we used descriptive statistics for determining frequency, mean, and standard deviation, as well as t- test, and ANOVA in order to analyze the data.
Findings: The results showed that spiritual health of the majority of the participants was from moderate to high level, and the mean score of their spiritual well-being was (88.98±7.35). The results indicated that the participants’ spiritual health is not related to any of the demographic variables.
Conclusion: The protection coming from religious or spiritual resources and having a relationship with a higher power can be useful for improving the quality of life and health promotion. Since the elderly people are considered as a vulnerable group in the society, the need for educational planning and counseling services in this field is crucial.

Aim: Malnutrition prevalence is unknown among elderly patients with diabetes. Nutrition therapy is an essential component in the treatment program for diabetics. Malnutrition is a clinical disorder and a common risk factor in older patients with diabetes, which can affect their health. The main purpose of this article is to evaluate the nutritional condition of elderly with diabetes in Babol City, Iran.
Methods: This cross-sectional study was done in Babol City during January-April 2017 on 200 older patients with diabetes. Malnutrition was assessed with the Mini-Nutritional Assessment (MNA) approach. The patients were followed up until discharge. Data analysis was carried out using descriptive statistics methodology, and correlation among variables was determined by the Chi-square, T-test, and One Way ANOVA.
Findings: The results showed that about 50% of the elderly patients were suffering from malnutrition, and 20% had normal nutritional status, and approximately 30% were exposed to malnutrition.
Conclusion: It is possible to identify people at risk for malnutrition. These individuals are suffering from malnutrition more likely due to lower level of caloric intake that can be easily corrected by nutritional intervention. It is necessary to improve the status of elderly diabetic patients with malnutrition suffering by administering normal nutritional status and special attention.

Research subject: Solvents are compounds that are used in the chemical, pharmacy, oil and gas industries, including in separation processes. These solvents include alkanolamines and ionic liquids (ILs). ionic liquids with a melting point below 100^oC are a particular class of chemical compounds that have unique properties and characteristics. Design and optimization of acid gases removal systems and separated CO₂ from the gas stream requires experimental data of physical properties, However, performing an experiment is time consuming and costly. Therefore, thermodynamic models are used to predict the properties of pure and mixture materials.
Research approach: In this study viscosities of 3 alkanolamines (Monoethanolamide (MEA), N-Methyldiethanolamine (MDEA), Diethanolamine (DEA)) and 12 ionic liquids based on imidazolium (imidazolium based families of tetrafluoroborate, hexafluorophosphate and bis[(trifluoromethyl)sulfonyl]imide) were investigated by the well-known friction theory (FT) based on friction concepts of classical mechanics was coupled with two simple cubic equation of state (EoS) of the Soave-Redlich-Kwong (SRK) and Peng-Robinson(PR) at over wide ranges of temperatures and pressure and in different mole fraction (for mixture) for prediction of viscosity. The models presented in this work are based on the viscosity behavior of pure alkanolamines and ionic liquids.
Main results: The result shows friction theory has good operation in prediction of viscosity. The average absolute Relative deviation (AARD) is 4.71% and 1.66% for pure ILs and alkanolamine respectively when PR equation state is used and when SRK equation of state is used these values is 4.70% and 1.99% about IL-IL mixture, experimental and predicted values were well matched and for IL-alkanolamine mixture FT5- and FT6- have best result.

Many linguists have studied argument structure and argument realization in causative/inchoative alternations within the framework of lexicalist approaches. In the present paper, we will study, criticize and compare various derivatives of lexicalist approaches. Subsequently, we will test the main hypothesis underlying the mentioned accounts. In these accounts it is assumed that the verb’s lexical semantic features determine its argument structure and alternation. In this paper, based on Persian data, we will show that verb’s lexical semantics plays an important role in determination of its alternation, but the verb’s participation in causative alternation cannot be attributed sole to the verb’s semantic content. Overall, the findings of this survey cast doubt on the results of previous researches and show that  other factors which transcend the verb’s lexical features determine its argument structure and its participation in causative alternation. With this regard, the other aim of this paper is to specify the factors affecting Persian verbs’ participation in causative alternation. Amongst these factors one can point to contextual factors such as semantic features of verb’s arguments and non-arguments alongside encyclopedic factors which coalesce at the level of logical form of the utterance.

Background: Tuberculosis (TB) is an infectious and communicable disease and one of the top ten causes of death throughout the world. Monitoring and evaluating TB treatment outcomes provides the required data for taking the necessary measures to control TB. Thus, this study was carried out to find determinants of treatment failure among patients with smear-positive pulmonary TB in Khuzestan province during 2006-2014
Materials & Methods: This retrospective cohort study was conducted over a 9-year period in Khuzestan province. Predictors of treatment failure were analyzed using multivariate logistic regression
Findings: Among 5342 patients, the cumulative incidence of unsuccessful TB treatment was 1.85%. More than half of TB patients (59.2%) enrolled in this study were male, and most of them were living in urban areas (79.8%). Significant predictors of treatment failure were age (p=·001), weight (p= ·039), number of delayed days in diagnosis (p=·01), isoniazid resistance (p≤·001), and number of bacilli in patients` sputum at the beginning of treatment (p≤·001).
Conclusion: In this study, the rate of successful treatment was quite high; nevertheless, new cases of treatment failure could be prevented with special efforts such as prompt diagnosis and precise follow-up under Direct Observation Treatment Short course (DOTS) strategy.

Aims: The aim of the current study was to determine the role of Avicennia marina’s primary production as well as other food sources in the diet of Longjaw thryssa, Thryssa setirostris (Broussonet, 1782) in an arid mangrove ecosystem using carbon stable isotopes of carbon (δ¹³C) and nitrogen (δ¹⁵N).
Material & Methods: We collected five potential food sources in the ecosystem including fresh and senescent leaves of Avicennia marina, particulate organic matter, microphytobenthos and sediment organic matter for further stable isotope analysis. Additionally, fishes were collected with a combination of set nets and seines. The muscle tissue (boneless and skinned, 5 g) was removed from the dorsum of fish.
Findings: Significant differences were found between carbon and nitrogen isotopes of different food sources (p < 0.05). Although, this was not significant for green and senescent leaves (p > 0.05). The average values of carbon and nitrogen isotopic ratios of T. setirostris were 15.93‰ and 13.01‰, respectively. The SIMMR model showed that the contribution of senescent and fresh leaves in the diet of T. setirostris was 15% and 10%, respectively.
Conclusion: The result of the current study emphasized a limited role for mangrove detritus in the diet of transient fishes in an arid mangrove ecosystem.

Enzymes of marine organisms are ideal candidates for biomonitoring of pollution in marine environments. For the widespread use of enzymes in industrial processes, carried out under certain physico-chemical conditions, their stability must be improved. In this study, for the first time, chitosan nanoparticles were used as matrices for augmenting the stability of Penaeus vannamei (Whiteleg shrimp)-derived purified proteases against metallic ions. For the electrostatic binding of the enzyme to the chitosan nanoparticles, the protein solution at a concentration of 7mg/ml was added to the nanoparticles, and incubated for 4 hours at 10°C. After 3 times rinsing with phosphate buffer of pH=7.5, the nano-enzyme was dissolved in 1ml phosphate buffer, and used for further studies. The results of this study showed that Fe²⁺ and Mn²⁺ significantly increased the enzyme activity, whereas a strong inhibitory effect was observed in the presence of Cd²⁺, Hg²⁺, Co²⁺, Ni²⁺, Cu²⁺ and Zn²⁺, and a weak inhibitory effect in the presence of Na⁺ and K⁺. The immobilized enzyme exhibited greater resistance to metal ions than its free counterpart. The free enzyme was susceptible to the presence of metal ions, and with the increment of their concentrations, enzyme activity declines. From this nexus, it could be inferred that the high stability of immobilized enzyme is due to the presence of chitosan nanoparticles. Stability retention of the immobilized enzyme at high concentrations of metal ions indicates the efficacy and utility of the immobilization method in industrial enzyme technology.

Aims: Although physical activity has many health benefits during pregnancy, few women engage in regular physical activity. The purpose of this study was to test the validity and reliability of a physical activity scale in pregnant women based on social cognitive theory.
Instrument & Methods: A multi-phase scale development method was used to build the scale. To generate a pre-final version of the instrument, face and content validity were measured at the following step. The validation of the instrument was evaluated through a sample of 240 pregnant women. Then, the construct validity, internal consistency, test-retest reliability, and Cronbach’s alpha of the scale were calculated.
Findings: In the beginning, a 36-item scale was created by undertaking a qualitative phase. This number was lowered to 24 items after content validity. Seven factors emerged from the exploratory factor analysis (outcome expectations, outcome value, self-efficacy, social support, self-regulation, mutual determinant, and behavior) which accounted for 52% of the observed variance. The confirmatory factor analysis revealed a model with a suitable fitness for the data. For the subscales, Cronbach's alpha coefficients ranged from 0.83 to 0.94, and the Intraclass correlation coefficient ranged from 0.80 to 0.88, which is within acceptable limits.
Conclusion: The findings showed that the psychometric properties of the physical activity scale is valid and reliable scale that can help us better understand aspects associated to physical activity in pregnant women. As a result, it has the potential to be employed in the future research.

Aims: Drought limits plant growth and productivity throughout the world. Narrow-leaved plantain (Plantago lanceolata L.) is widely used to treat some human diseases and reduce antibiotic nutrition. This study aimed to examine the response of four local ecotypes of P. lanceolata to different drought stress levels in a field experiment.
Materials & Methods: A split-plot design was conducted using a randomized complete block design (RCBD) with three replications at the farm of Research Institute of Forests and Rangelands, Karaj, Iran, 2018. The main factor was drought stress at three levels (D1= normal irrigation, D2= drought stress after the flowering stage with supplemental irrigation at the filling stage, and D3= stop irrigation after flowering. The second factor contained four ecotypes: G1-Arak, G2-Khoramabad, G3-Meshkinshahr1, and G4-Meshkinshar2. Data were collected and statistically analyzed for grain yield and yield components.
Findings: Results showed a significant effect of drought stress and ecotype on all traits except root lengths (p<0.05). The ecotype × drought stress interaction effects were significant for spike number per plant, leaf number per plant, leaf width, and plant height (p<0.05). The mean values of grain yield in D1, D2, and D3 were 729.41, 660.81, and 595.95 kg.h^-1, respectively.
Conclusion: The highest grain yield of 670.92 kg.h^-1 was obtained from G1-Arak. This ecotype produced higher grain yields under mild and severe stress than the other ecotypes and was recommended for breeding improved varieties.

We studied the abundance, biomass and diet of Platevindex aff. tigrinus in the Hara Biosphere Reserve in the Persian Gulf. The seasonal sampling (two seasons) was conducted in winter 2018 and summer 2019. Samples were collected from six sites in Qeshm Island and Bandar Khamir. To determine the effect of environmental parameters on distribution of the species, temperature, salinity, pH, sediment grain size, total nitrogen and organic carbon were measured at each site. The results showed that the abundance of P. tigrinus was significantly higher in the winter compare to summer season. However, there was no significant difference in the biomass of the species between seasons. The PCA results showed that salinity, temperature and sediment grain size contributed to the separation of between seasons. The pH and total nitrogen followed the similar pattern in different sites and seasons. Although, temperature, salinity, sediment grain size, and organic carbon showed difference between seasons. The results showed that salinity and temperature were two important parameters in the distribution of the species during both seasons. The species was mainly feeding on the microphytobenthos during winter and on the sediment organic matter during summer.
