- چکیده انگلیسی: Optimization of process parameter is one of the ideal goals in laser sintering. The results of this process were measured as output parameters like: density, micro hardening, macro hardening, tension, roughness, stiffness, balling. In this paper, the influence of input parameter such as laser power, scan speed, material powder and etc are surveyed on output parameter like balling affection and the thickness of a layer. Iron and copper powder were used in this experiment in order to produce a full density single layer on 5 mm depth bed powder. One of the efficient factors on this process is overlapping which has a reverse impact on the high and low pulse power. Finally a coupon was produced with the best setting.

- چکیده انگلیسی: Water deficit is the most common environmental stress factor that is effective on plant growth and development. Polyamines are as growth regulator in plants and increased their tolerance to abiotic stresses such as drought. In this research the effect of foliar application of putrescine (40 and 60 µM) on shoot and root soluble and insoluble sugars and leaf proline contents in safflower plants under different levels of water supply (100% and 40% field capacity) was studied as factorial arrangement based on complete randomized block design with three replications. The effects of water deficit and putrescine on proline content in leaf and soluble sugars content in shoot and root were significant. Shoot soluble sugars and leaf proline increased under drought stress, but insoluble sugars decreased. Proline content in leaf and soluble sugars in shoot and root significantly decreased by application of 40 and 60 µM putrescine under water deficit. Putrescine as osmolyte and reactive oxygen species scavenger reduced production and accumulation of compatible osmolytes. In non-stressed plants, effects of putrescine treatment on soluble sugars content in shoot and proline content in leaf were different related to concentrations. Insoluble sugars increased with both concentration of putrescine in shoot and decreased in root. Putrescine application could enhance resistance of safflower to drought without increasing osmolytes biosynthesis.

- چکیده انگلیسی: Security is the infrastructure of any development. The most important need of any society is providing the security of it and its individuals, which is why putting effort for providing the security and developing its domain is one of the most important goals of countries in international relations realm and their domestic policy. Striving for increasing national security limit is one of the most underlying concerns of the governments. There is a defined relationship between tourism and security development. Developing tourism in countries is only possible in the ones possessing required security. Tourism destinations are widespread in country, and through providing security in these regions, social security coefficient is increased resulting in tourism development. Security is a vital effective factor in attracting tourists to traveling and tourism. A tourist who decides to travel all around the world will dismiss their decision if they feel there is no security in host country.

- چکیده انگلیسی: Strong brands bring numerous benefits for both the companies and their customers such as decreasing purchasing risk and searching cost and increasing the likelihood of repurchasing. It is not presented an applied model for determining the price of this asset in Iran, especially in terms of merger and acquisition. The purpose of this study is to develop a model for pricing brand value in Iran’s capital supply companies in terms of marketing strategies of merger and acquisition. The current study is qualitative research which is done by conducting grounded theory in MAXQDA software. Needed data were gathered from interviews and panel sessions with all the 21 pricing experts in capital supply companies during the year 2018, and were analyzed to extract the variables of the model of brand pricing to Rial. After that, open codes were categorized into 5 main categories and 2 sub-categories titled as: communication and performance environmental factors, marketing, brand, performance (financial and non-financial), and corporate audit reports. Research findings; in addition, has developed an operational brand pricing model for Iran’s semi-public economy that is unprecedented in other studies.

- چکیده:
- چکیده انگلیسی: Lithium ion batteries are among the most used rechargeable batteries in the world. Carbon nanostructures including carbon nanotubes (CNTs) are considered as important electrode materials for this kind of batteries. Therefore improving the performance of these carbon based electrodes in Lithium ion batteries is an important issue and attracts much attention in the battery community. In this manuscript, a new method for high content Nitrogen doping on CNTs is reported as an efficient approach for enhancing the battery performance. Direct current-plasma enhanced chemical vapor deposition (DC-PECVD) system was used for nitrogen doping. Annealing with Nitrogen during CNT growth and plasma exposure after the growth has been used for Nitrogen doping of the CNTs. The growth was performed on an Indium Tin oxide (ITO) covered Silicon substrate. Implementation of Silicon substrate enables the possibility of future integration of other electronic circuits with the fabricated Lithium ion battery. Vertically aligned CNTs with an average diameter of around 150 nm and 4 um height has been obtained on this substrate. The synthesized CNTs was subsequently used as the electrode of Lithium ion battery in a half cell configuration. The results show a significant improvement of about 400% in the specific capacity of the battery as a result of Nitrogen doping. For Nitrogen doped CNT based battery, specific capacity of around 0.4 mAh/cm2 and coulombic efficiency of 97% were achieved after 28 cycles of charge/discharge with C rate of 2.5. This Nitrogen doping method is propped as an efficient technique for enhancing the performance of Lithium ion batteries with carbon based electrodes.

- چکیده:
- چکیده انگلیسی: Writing and speaking are the productive skills of a language and share similar components. However, there has been little attempt to investigate the impact of writing practice on the speaking proficiency of the learners. The present study using a pretest-posttest controlled group design in a quasi-experimental approach investigated the effect of guided writing practice on the speaking proficiency of Iranian EFL students. Two elementary intact classes which were classified based on the institute’s placement test were selected for the study. The homogeneity of the learners was checked through Key English Test (2007) as the pretest of the study, and the classes were randomly assigned into the experimental group (n=26) and the comparison group (n=26). The experimental group was provided with 10 guided writing worksheets in the last 15 to 20 minutes of the class, whereas the comparison group went through the procedure of a typical institute class in which they worked on workbook exercises during the mentioned time. The quantitative analysis of the posttest using an independent samples t-test indicated that not only writing proficiency, but also the speaking proficiency of the experimental group had significantly improved. Moreover, an end of the term a semi-structured interview sought the experimental group learners’ attitudes toward the role of writing practice in improving their speaking skill. The content analysis of the interview transcripts revealed that the learners held positive attitudes toward the guided writing worksheets at the end of the term, though they did not have the same attitude at the beginning.

- چکیده:
- چکیده انگلیسی: The nanocomposites of poly (Acryl amide-co-Acrylic acid) with different contents of NaA
zeolite were prepared using ammonium persulfate as an initiator and N, N′-methylene
bisacrylamide as the crosslinker. The morphology was characterized by SEM and the structure of
nanocomposite materials was studied with XRD and FT-IR that showed the interaction between
porous materials and poly (AAm-co-Aac). The adsorption behaviors of methylene blue were
investigated for nanocomposites. It was shown that poly (AAm-co-AAc)/NaA nanocomposites
have higher adsorption than NaA and poly (AAm-co-AAc) alone. This effect was attributed to
good interaction between the hydroxyl group in porous materials and carboxylic group in poly
(AAm-co-AAc) with methylene blue.- انتشار مقاله: 14-04-1389

- چکیده انگلیسی: Rice as one of the most important agricultural crops has a putative potential for ensuring food security and addressing poverty in the world. In the present study, in order to provide basic information to improve rice through breeding programs, Inter Simple Sequence Repeat marker (ISSR) was used For DNA fingerprinting and finding genetic relationships among 32 different cultivars. In this study, 12 out of 17 used primers amplified 184 distinct and reproducible fragments with high value of polymorphism (88%). also, for fingerprinting the cultivars 29 loci were used that generated high polymorphic bands among the cultivars. Results indicated that similarity index varied between 39% and 88.4 %, furthermore, PIC value with an average of 23% ranged between 0.1 (for primer #3) to 0.34 (for primer #2). Clustering based on Jaccard coefficient similarity index and UPGMA algorithm divided the cultivars into 6 main sub-clusters in cut-off point of 64% similarity index. The two Italian rice cultivars ‘Ribe’ and ‘Roma’ were the closest cultivars in addition, ‘Vialone nano’ and ‘Anbarbu’ showed the highest dissimilarity. In total, high genetic divergence was observed among the cultivars also, poly (GA)-containing 3-anchored primers amplified the highest number of bands. According to similarity and cluster analysis, it could be inferred that crosses involving Anbarbu cultivar are the most promising ones to improve rice through breeding programs. In fact, results of this study would be promising as a genetic marker for the identification of rice cultivars and an important source of knowledge for subsequent rice researches.
