Culture refers to the manner of thinking and work performance among the individuals and is deeply rooted in the presumptions, beliefs and symbols of each society. Certainly, people will also highly care for their cultural belongings. People of cities like Soltanieh who have constant interactions with their guests from different cultures because of tourism attractions in their city should have and enhance in themselves a capability so that they may cause the minimum damages and restrictions in the inter-cultural interactions. Having three aspects, namely Cognitive aspect, Motivational aspect and Behavioral aspect, cultural intelligence indicates a capability by which the people may experience the best interaction when encountering unfamiliar cultures. Such capability in tourism, whether in the position of a tourist or a guest, causes people to show the best possible behavioral responses and to manage the mutual interpretations when encountering other people and cultural phenomena by having a general understanding of cultures and their positions. Using surveying method, in this paper we study Soltanieh City as one of the important tourism centers of Iran. Spearman Correlation Coefficient and Friedman Rank Test were used for statistical study. The results indicate that enhancement of cultural intelligence affects on the increase of tourists` intercultural interactions efficiency.

Immobilization of L-Lysine on Zeolite 4A as an Organic-Inorganic Composite Basic Catalyst for Synthesis of α,β-Unsaturated Carbonyl Compounds under Mild Conditions

Zamani, Farzad,Rezapour, Mehdi,Kianpour, Sahar Korean Chemical Society 2013 Bulletin of the Korean Chemical Society Vol.34 No.8

Lysine (Lys) immobilized on zeolite 4A was prepared by a simple adsorption method. The physical and chemical properties of Lys/zeolite 4A were investigated by X-ray diffraction (XRD), FT-IR, Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and UV-vis. The obtained organic-inorganic composite was effectively employed as a heterogeneous basic catalyst for synthesis of ${\alpha},{\beta}$-unsaturated carbonyl compounds. No by-product formation, high yields, short reaction times, mild reaction conditions, operational simplicity with reusability of the catalyst are the salient features of the present catalyst.

Mohammad Mehdi Moftakhari Sharifzadeh,Abtin Ebadi Amooghin,Mona Zamani Pedram,Mohammad Reza Omidkhah 한국공업화학회 2016 Journal of Industrial and Engineering Chemistry Vol.39 No.-

In this study, a comprehensive time-dependent mathematical model for gas separation through thefacilitated transport membranes (FTMs) is presented. The model results have been validated withindependent CO2/N2 binary gas mixture experiments in DEA-impregnated PVA membranes. In theproposed model, non-equal diffusion coefficients of the carrier/complex and equilibrium constant for thechemical reaction kinetics between the carrier/permeant in the FTM have been considered. In addition, amethod to compute the diffusion coefficients, which depend on the concentration of each component inthe FTM, is presented. Moreover, effect of carrier concentration, feed partial pressure, kinetics ofreversible chemical reactions and membrane performances depending on operating condition have beenanalyzed. Owing to accurate calculation of physical–chemical parameter involved, this model is muchmore executive comparing to previous works. In addition, the real condition of the reaction kinetics andinfluencing of diffusion parameters of the components in FTMs, have been investigated. The predictedselectivity and permeability revealed good conformity with experimental data; with standard deviation(SD) 8.57% and 12.87%, respectively. In conclusion, this model with significant validity would bepredictive in cases for the entire range of diffusion-limit to a chemical-limit regime where theexperimental data, geometry condition, physical–chemical property of parameters is not available.

An exact solution for stresses and displacements of pressurized FGM thick-walled spherical shells with exponential-varying properties

Mohammad Zamani Nejad,Majid Abedi,Mohammad Hassan Lotfian,Mehdi Ghannad 대한기계학회 2012 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.26 No.12

Exact closed-form solutions have been derived for stresses and the displacements in thick spherical shells made of functionally graded materials with exponential-varying properties subjected to internal and external pressure. Poisson’s ratio is assumed to be constant. The obtained results show that the inhomogeneity properties of FGMs have a significant influence on the displacement and stresses distribution along the radial direction. A numerical solution using finite element method is also presented and good agreement was found between the analytical solutions and the solutions carried out through the FEM. The values used in this study are arbitrarily chosen to demonstrate the effect of inhomogeneity on displacements and stresses distributions.

Bagheri Mehdi,Zadehbagheri Mahmoud,Kiani Mohammad Javad,Zamani Iman,Nejatian Samad 대한전기학회 2023 Journal of Electrical Engineering & Technology Vol.18 No.3

In this paper, using an algorithm based on the combination of data based on neural network virology and bacterial nutrition algorithm, improves the performance of the neural network prediction method. Also, the selection of two types of downstream and upstream filters in the wavelet transformation increases the predictive efficacy of neurological prediction. Based on the results, the optimized clustered neural network method has a more favorable response than the other methods. By selecting the appropriate filter and multichannel processing method, the maximum error percentage has improved by 15%. However, compared to the neural network prediction method, the proposed method has more computational volume due to the use of wavelet transform and also three times the use of neural prediction. Due to the large number of layers and used neurons, the neural network method has a much higher computational volume than the linear prediction method, where the linear prediction method has a higher error than the proposed method depending on the data used for training.

Experimental investigation of the effect of baffles on the efficiency improvement of irrigation sedimentation tank structures

Alireza Zamani Nouri,Mohammad Mehdi Heydari 국제구조공학회 2017 Structural Engineering and Mechanics, An Int'l Jou Vol.63 No.4

Sedimentation tanks are essential structures to filter the suspended sediments in the inlet flow which are constructed at the inlet of the basins forked from rivers and irrigation canals. The larger the constructed tank, the better the sedimentation process is conducted. However, the construction and dredging costs increase. In this regard, improving the performance and sedimentation efficiency seem necessary by alternative methods. One of these effective methods is using baffle plates. Most of the studies carried out in this field are on the use of these baffles in the primary and secondary sedimentation tanks. Hence, this study is carrier out with the objective of increasing the retention efficiency in the irrigation sedimentation tanks using baffles. To reach this goal, the experiments were carried out in a flume with length 8 meters, width 0.3 meters, and height 0.5 meters, considering a sedimentation tanks with a length of 3 meters, in three different inlet concentration, three flow rates and three Froude numbers. The baffles were mounted at the bottom of the tank and the effects of the angle, height and position in the tanks were investigated. The results showed that on average, employing the baffles increased the sedimentation efficiency 5 to 6% and the highest value was obtained for angle 60 with respect to the flow direction. According to the results of this study, the most favorable height and position of these baffles were obtained to be in 40% of the depth of the flow and 50% of the length of the sedimentation tank, respectively. Also, by increasing the number of baffles, the sedimentation efficiency decreased. Regarding the sedimentation regions in this case, more than 80% of the settled sediments were observed in the middle of the tank measured from the inlet.

Niko Faraji,Mehdi Mahmoudian,Asghar Zamani 한국고분자학회 2024 폴리머 Vol.48 No.1

In this research, the nanofibrous polystyrene /titanium dioxide nanotube (PS/TiO2 nanotubes) membrane was prepared by the electrospinning method. Titanium dioxide nanotubes were synthesized by the anodizing method and stabilized on the fibrous polystyrene membrane. Then, the effect of different weight percentages of titanium dioxide nanotubes on the performance of the resulting membranes was investigated. The nanoparticles and nano-composites prepared in this research were analyzed using several analyses, including Fourier transform infrared spectroscopy (FTIR) and field emission scanning electron microscopy (FE-SEM), along with X-ray energy diffraction spectroscopy (EDS). The thermal behavior and crystal structure of prepared nano-composite membranes were investigated using (TGA) analysis and X-ray diffraction (XRD), respectively. Afterward, to investigate the prepared structures, analyses such as porosity measurement, water contact angle, swelling, and water flux of the membranes were performed. The photocatalytic property of the prepared membranes in the decomposition of methylene blue was investigated by two methods (static and dynamic). The obtained results demonstrated that the dye removal was accomplished in the best way in the static method (using the membrane as an absorbent) for 48 h. The prepared nano-composite membranes were also used in the dye filtration removal process, and the best result was obtained by using the membrane containing titanium dioxide nanotubes with a concentration, of 0.05 gr/V(50). The swelling degree in the fibrous polystyrene membrane was 135%, while in the membrane containing 0.1% titanium dioxide nanotubes, which is the optimal membrane, was 66%. Hydrophilicity measurements by water contact angle revealed that the presence of TiO2 nanotubes improved by about 10%.

Prevalence of Colorectal Polyps in a Group of Subjects at Average-risk of Colorectal Cancer Undergoing Colonoscopic Screening in Tehran, Iran between 2008 and 2013

Sohrabi, Masoudreza,Zamani, Farhad,Ajdarkosh, Hossien,Rakhshani, Naser,Ameli, Mitra,Mohamadnejad, Mehdi,Kabir, Ali,Hemmasi, Gholamreza,Khonsari, Mahmoudreza,Motamed, Nima Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.22

Background: Colorectal cancer (CRC) is one of the prime causes of mortality around the globe, with a significantly rising incidence in the Middle East region in recent decades. Since detection of CRC in the early stages is an important issue, and also since to date there are no comprehensive epidemiologic studies depicting the Middle East region with special attention to the average risk group, further investigation is of significant necessity in this regard. Aim: Our aim was to investigate the prevalence of preneoplastic and neoplastic lesions of the colon in an average risk population. Materials and Methods: A total of 1,208 eligible asymptomatic, average- risk adults older than 40 years of age, referred to Firuzgar Hospotal in the years 2008-2012, were enrolled. They underwent colonoscopy screening and all polypoid lesions were removed and examined by an expert gastrointestinal pathologist. The lesions were classified by size, location, numbers and pathologic findings. Size of lesions was measured objectively by endoscopists. Results: The mean age of participants was $56.5{\pm}9.59$ and 51.6% were male. The overall polyp detection rate was 199/1208 (16.5 %), 26 subjects having non-neoplastic polyps, including hyperplastic lesions, and 173/1208 (14.3%) having neoplastic polyps, of which 26 (2.15%) were advanced neoplasms. The prevalence of colorectal neoplasia was more common among the 50-59 age group. Advanced adenoma was more frequent among the 60-69 age group. The majority of adenomas were detected in the distal colon, but a quarter of advanced adenomas were found in the proximal colon; advance age and male gender was associated with the presence of adenoma. Conclusions: It seems that CRC screening among average-risk population might be recommended in countries such as Iran. However, sigmioidoscopy alone would miss many colorectal adenomas. Furthermore, the 50-59 age group could be considered as an appropriate target population for this purpose in Iran.
