This study employs graph theory to analyze the semantic network of Persian verbs among bilingual speakers. Situated within the frameworks of cognitive linguistics, lexical semantics (cognitive semantics), and computational linguistics, the research involves administering a questionnaire comprising 50 basic Persian verbs to participants, asking them to map the conceptual and intra-linguistic relationships between these verbs.The primary objective is to identify the most robust and frequent conceptual and intra-linguistic links among these verbs and to provide a detailed description of the graph structure constructed by bilingual speakers. The study seeks to address the question: What typology of conceptual and intra-linguistic relations is reflected in the graph patterns of non-Persian-speaking Iranians? The working hypothesis posits that semantic relations such as synonymy, antonymy, hyponymy, and collocation will manifest in this network.The methodology is field-based, and the instrument used is a localized questionnaire. Participants were instructed to diagrammatically represent any semantic relationships among the verbs provided.The findings demonstrate that the semantic graph constructed by Iranian bilinguals exhibits semantic relations such as synonymy (6.45%), reverse antonymy (34.94%), polysemy (7.79%), entailment (11.01%) (comprising "type-of" relations at 8.60% and "part-of" relations at 2.41%), as well as intra-linguistic collocation (28.22%). Among these, collocation, entailment, and antonymy were the most frequent relations, respectively.

Background: Knee osteoarthritis (OA) is a major public health problem leading to chronic pain and increased years lived with disability This study aimed to assess lifestyle behavioral management in patients with Knee osteoarthritis among Iranian patients up to 6 months.
Methods and Materials: This study conducted at the Rheumatology Research Center of Tehran University of Medical Sciences (TUMS) in Tehran, Iran. In this educational controlled trial study, 130 eligible participants took part in control group (n = 66) and received just prescribed medications, or intervention group (n = 64) who received the lifestyle behavioral management plus medication. The program involved three two-hour and two one-hour group sessions over a one-week period. Data based on demographic characteristics and risky behaviors questionnaire as well as Functional Knee Assessment Test (FKAT) were collected at initial, 3-, and 6-month follow ups and analyzed by using SPSS₁₈.
Results: Of 130 participants, five individuals from intervention and eight individuals from control group were excluded over 6 months. Totally, 117 eligible participants in two groups of intervention (n = 59), and control (n = 58) completed the study. The mean age of participants in intervention and control group at base line was 59. 03 ± 6. 13 and 57. 85 ± 9. 31 years respectively. Despite being the same at initial time (P > 0. 05), Repeated Measure ANOVA test showed Significantly better improved disability in intervention group over time (P < 0. 001). Compared with control group, preventive behaviors were improved significantly in intervention group (P < 0. 05)
Conclusions: This study revealed that the multidisciplinary program could significantly reduce risky behaviors and disability up to six months in intervention group. Thus, due to lack of lifestyle behavioral management in health care system of Iran, to embedding this program into clinical practice for managing knee OA pain is recommended.

Background: This study is an extended follow up of the original trial study (NCT00600197) that has been published in the clinical journal of pain. This trial aimed to explore if the proposed multidisciplinary program could improve quality of life and disability of the patients suffering from chronic low back up to 36 months. Methods and Material: In this Clinical Randomized trial seventy percent (139 of 197) of the participants who had taken part in the original study including 66 patients in intervention group and 73 patients in control group were followed up to 36 months after intervention. The intervention group continued receiving monthly motivational consultation and booster classes plus oral medication but the other group received just medication. Data on measures of Short Form 36 (SF-36) Quebec Disability Scale (QDS) and Ronald Morris Disability (RDQ) were collected at 3-6-12-18-24-30- and 36-month follow ups and analyzed through RMANOVA. Results: The 2 groups were comparable regarding all baseline characteristics (P > 0.05) except for education level that was better in intervention group (P = 0.01). Two groups were improved regarding all studied variables over time up to 36 month (P < 0.001) Moreover the intervention group in comparison with the control group had consistently better outcomes regarding all variables. There were no significant differences within each group by time in terms of all variables (P < 0.05). Conclusions: The proposed multidisciplinary program could reduce low back pain and improve quality of life and disability up to 36 months in chronic low back pain patients.

Archetype is the common experience of mankind that has remained of distant past in collective unconscious. Because human experiences are abundant, we can not be identify the number of archetypes, but the most significant archetypes are: anima, animus, self, persona, shadow, wise old man and mother. Sacrifice is one of the major archetypes that have been institutionalized in the collective unconscious of most humans. In psychoanalyst viewpoint, sacrifice is one of the defensive mechanisms of humans against the demands of the id that leads to social interest. Archetypes are shown in dreams, imagination and illusions. Art (especially literature), is one of the main manifestations of archetypes. Sacrifice and its features can be found in the large number of artworks. In this paper, we investigated the archetype of the "Sacrifice" in Hallaj, in "Hallaj's poetry" of Mohammadreza Shafiei Kadkani, and "Hallaj's requiem" of Adonis, and presented a mythical criticism of them.

Aim: This is a cross- sectional study to assess low back pain preventive behaviors among Iranians nursing aides who provide direct patient care in hospitals. Musculoskeletal disorders (MSDs) comprise significant occupational injuries and disabilities within the nursing profession. Studies show that implementing a safe patient handling can prevent low back pain among nursing aides. Methods: This study was conducted in Qom (Iran) in 2015 with a sample of 452 eligible nursing aides working in six educational hospitals affiliated with Qom University of Medical Sciences. Data were collected by a researcher-developed questionnaire with 29 questions in two sections of demographic questions (17 items), and low back pain preventive behaviors were adopted from the Occupational Safety and Health Administration (OSHA) guidelines for nurses (12 items). Findings: Totally, 452 nursing aides suffering from chronic low back pain participated in the study, which included 289 males (63.9%) and 163 females (36.6%) with mean age of 37.71 (SD = 8.3) years. The mean score of applying low back pain preventive behaviors was 32.9 ± 7.7. Fifty nine participants (13.1%) had poor behavior scores, 251 participants (55.5 %) obtained average scores, and 142 participants (31.4 %) achieved acceptable scores due to their preventive behaviors. The majority of the studied nursing aides (68.6%) did not consistently perform safe patient handling. Conclusion: This study showed that most nursing aides had low preventive behaviors regarding maintaining their body mechanics. Thus, evaluating the causes of failing to do safe behaviors /safe patient handling  is strongly recommended in Iran.

Background: Brucellosis is one of the most prevalent infectious diseases in Iran, which is shared between humans and animals. Brucellosis is caused by Brucella  species and transmitted via unpasteurized milk or dairy products, which has been reported at least in 80 countries.The present study aimed to evaluate the prevalence rate of seropositive cases of brucellosis in Yazd, Iran.
Materials and Methods: In this retrospective cross sectional study, seropositivity rate of brucellosis was examined for 12258 patients. The Wright test (1.80 or higher) was used for diagnosing brucellosis. The obtained results were statistically evaluated by chi-square which is a trend analysis method.
Results: The seropositivity rate of Wright test was reported to be 178 (1.5%), which was significantly higher in the summer (43.3%) and spring (29.7%) than other seasons (P = .000). It was also significantly higher in men (53.9%) (P = .000) than in women, and in people over 40 years (41%) (P = .000) than in other age groups.
Conclusion: Brucellosis seropositive studies provide very good information in order to help us in investigating the impact of brucellosis.

Water erosion causes a series of on-site as well as off-site damages and problems on natural ecosystem. These damages include soil and nutrient loss and finally loss of productivity which causes costs to the society. So, this study attempts to quantify the economic value of soil productivity conservation as one of the important functions of rangelands vegetation and its economic cost by productivity losses. The soil loss amounts were obtained from integrated Geographic Information System (GIS) and map of erosion vulnerable areas using RUSLE model. Supplementary data such as soil nutrients (NPK) valuated from the measurement plots of a portable rainfall simulator (E65). Field plots were constructed to measure soil nutrients and soil loss from different soil types with different resistance to erosion. Rainfall simulation was carried out in three sites on the basis of geology map and different resistance to erosion. Nine experimental unit plots (1*1 m) were used to correlate nutrient loss to sediment losses. Assuming that nutrient loss by erosion could be replaced by fertilizers, economic cost of major nutrients estimated by market prices of fertilizers. Results showed that mean annual soil loss using RUSLE was 27.44 t ha^-1 y^-1 ranging from 0.0 to 996.06 t ha^-1 y^-1. Also, 114.17 kg ha^-1 y^-1 of N, P, K elements were lost in 2010 due to soil erosion in the degraded rangelands which costs (738944 Rial) 71.5 US$ ha^-1y^-1. Total economic cost of soil nutrient loss in 94978.6 ha of the rangelands of Nour-rud watershed basin, was estimated 70×10^{^}9 Rial (6.8×10⁶ US$). The maximum annual cost of soil nutrient loss was estimated in the "TRujs" geological formation (1.23×10⁶ US$) consisting of "gray shale, silt, sandstone, conglomerate" and the least cost belonged to the "Jl1" geological formation (0.916*10⁶ US$) which consists of "thin gray dolomite limestone". In economic terms there was a direct relationship between soil nutrient loss and its economic cost.

Sugar beet molasses is a well-known, inexpensive and available carbon source for microbial cell growth. Its sugar components are used to produce energy for microbial growth and non-sugar components, especially nitrogen components, have important roles in improvement of cell growth. On the other hand, immobilization of whole cell is establishment and physical limitation of intact cells in specific space that keeps their catalytic activity and provides the possibility of reuse of the cells. This technique allows continuous and accelerated biological processes. It also improves production efficiency and quality and simplifies recycling of product. Immobilized living cells, as controlled catalysts, are able to perform one-step enzymatic reaction and continuous fermentative processes. In this research, E.coli cells were immobilized in calcium alginate hydrogels and using sugar beet molasses as carbon source, were applied for tryptophan production reaction in the presence of its precursors, serine and indole. In comparison between free biocatalysts and immobilized bacterial cells that entrapped in alginate gels, indicated that larger amounts of amino acids (about 42/9%) can produce in calcium alginate. Also the production reaction was followed up for 9 sequential cycles, and results showed that the cells could produce tryptophan amino acid under above conditions. Use of sugar beet molasses (by-product of agriculture industries) for growth of microbial cells and tryptophan production, causes decrease in production cost and more economical production of tryptophan by immobilized E. coli.
