New Traveling-Wave Antenna Resonating at 6 GHz Based on Artificial Transmission Line Metamaterial Structures for RF Portable Devices  [PDF]
Mohammad Alibakhshi Kenari
Open Journal of Antennas and Propagation (OJAPr) , 2013, DOI: 10.4236/ojapr.2013.12003
Abstract: Design of new metamaterial (MTM) traveling-wave antenna with “d-formed” left-handed structure is proposed. The proposed MTM structure is designed at a height of 0.8 mm from the ground plane with almost 2 GHz bandwidth. The most interesting feature of the design is the ability of enhancing the gain and total efficiency of the antenna without negative effects of the other important parameters like bandwidth. By using the “d-shaped” MTM structure and printed planar technique, the bandwidth of the MTM traveling-wave antenna is significantly increased at a resonant frequency of 6 GHz and also a foot print area reduction of the antenna structure is provided. Antenna size is 7.2 × 5 × 0.8 mm3. The proposed antenna is suitable for RF portable devices operating at 6 GHz.

Advances in Applied Sociology (AASoci) , 2014, DOI: 10.4236/aasoci.2014.42010
Abstract:

Nowadays, evidence-based education with a serious purpose, more explicit and rational than the best current evidence to decision-making in nursing education, has been addressed. This study aimed to assess the effect of clinical evidence based on the fact that the quality of patient care has been performed and the usual care based on traditional evidence-based care training has been under almost identical. Student feedback questionnaire data, patient satisfaction and quality of care were collected and then were analyzed with descriptive and inferential statistics. This study suggests that the using evidence-based education in nursing care is effective not only as traditional education, but also as knowledge and skills, and the quality of patient care increases. On the other hand, it will reduce costs and length of stay in the hospital.

The Philosophy and Neuroscience Movement  [PDF]
Morteza Alibakhshi Kenari
Art and Design Review (ADR) , 2014, DOI: 10.4236/adr.2014.22004
Abstract:

A movement dedicated to applying neuroscience to traditional philosophical problems and using philosophical methods to illuminate issues in neuroscience began about thirty-five years ago. Results in neuroscience have affected how we see traditional areas of philosophical concern such as perception, belief-formation, and consciousness. There is an interesting interaction between some of the distinctive features of neuroscience and important general issues in the philosophy of science. And recent neuroscience has thrown up a few conceptual issues that philosophers are perhaps best trained to deal with. After sketching the history of the movement, we explore the relationships between neuroscience and philosophy and introduce some of the specific issues that have arisen.

Morteza Alibakhshi Kenari
Advances in Applied Sociology (AASoci) , 2014, DOI: 10.4236/aasoci.2014.43011
Abstract:


In the last twenty years, a lot of attention to issues of psychology and psychotherapy are associated with physical activity. Due to the increasing rate of mental disorders in country, this study attempts to compare the health of athletes and non-athletes in Beheshti University. Mental Health in schools will also compare. In this study, the health measured using the General Health Questionnaire GHQ-28 has performed. University students participated in this study of 260 patients who were randomly selected to represent the school. Statistical methods are used for the analysis and comparison of two sample t-test. The results show that the significant differences of symptoms of physical, anxiety, sleep disorder, social dysfunction and depression in the two groups were observed between athletes and non-athletes. The college student mental health and physical education than other students in four scales were much more favorable situation.

Tehran University Medical Journal , 2012,
Abstract: Background: Gastric cancer is an important health problem across the world. Chemotherapy in combination with local treatment is the standard treatment for locally advanced gastroesophageal junction (EGJ) cancers. The purpose of this study was to evaluate response and tolerability to neoadjuvant regimen combining epirobicin, oxaliplatin and capecitabin (EOX) in locoregionally advanced gastric cancer.Methods: We recruited 28 patients with histologically confirmed advanced gastric or EGJ adenocarcinoma in this study performed in the Cancer Institute of Imam Khomeini Hospital in Tehran, Iran in 2010-2011. Staging workup included chest and abdominal computed tomography (CT) scans, upper gastrointestinal endoscopy, endoscopic ultrasonography (EUS), measurement of carcinoembryonic antigen (CEA), complete blood cell count (CBC), and liver and renal function tests. After three treatment cycles with EOX regimen, we evaluated response to the neoadjuvant chemotherapy by performing endoscopic ultrasonography (EUS) and chest and abdominal CT scans.Results: The mean age of the patients was 56.64±11.08 years (ranging from 37 to 78 years). Most patients were classified as having stage III (98.8%) cancer before chemotherapy while most were classified as stage II (57.14%) after the treatment. Only 28.5% of tumors were resectable before chemotherapy, but 82.1% of them were resectable upon the treatment. 75% of tumors were downstaged after chemotherapy.Conclusion: Regarding the acceptable response and downstaging of tumors and low toxicity of EOX regimen in locoregionally advanced gastric cancer, evaluation of this regimen as a neoadjuvant chemotherapy in larger phase III clinical trials in Iranian patients would be both necessary and logical.

This fact is somehow different for localized peritonitis (e.g. acute appendicitis) in which the clinical presentation directs straightly to the diagnosis. However, acute appendicitis has lots of differential diagnoses, finding the normal appendix during laparotomy is just a start point to look for other diagnoses. Omental torsion is a rare cause for acute abdomen that is usually missed. Knowing about this rare condition and its frequently encountered presentation at the operating room (sero-sanguinous fluid coming out of peritoneal cavity) may prevent missing the diagnosis and doing a malpractice."n"nCase report: Report a 9 year- old boy presented with acute abdomen which turned out to be an omental torsion after the operation."n"nConclusion: Knowledge about this rare condition "omental torsion" and its clinical and intra operative presentations may prevent missing the diagnosis and a malpractice.

Goudarz Alibakhshi,Davood Padiz
Journal of Language Teaching and Research , 2011, DOI: 10.4304/jltr.2.4.941-947
Abstract: Communicative strategies have always been of much concern to applied linguists. Whether teaching communicative strategies has any significant impact on second language learners’ speaking or not has also controversial among language teachers. This study aimed at investigating the effect of explicit teaching of some of the communicative strategies (CSs) on language performance of Iranian language learners of English. It was also an attempt to study the stability of teaching CSs. The participants of the study were 60 male and female language learners. The experimental group received a 10-week-treatment on CSs. The data were gathered through three oral production tests consisting of the same tasks including group discussion, story retelling, and picture description. The data were analyzed through descriptive and inferential statistics (Chi-square test). The results of the study indicated that there was significant difference between control and experimental groups in the use of CSs; whereas, the results of the first posttest showed that there was a significant difference between the groups in the use of seven out of the nine strategies. Moreover, the results indicated that the effect of teaching CSs was stable even after a long interval.
Mutation Analysis of CFTR Gene in 70 Iranian Cystic Fibrosis Patients
Reza Alibakhshi,Mahdi Zamani
Iranian Journal Of Allergy, Asthma and Immunology , 2006,
Abstract: Cystic fibrosis (CF) is the most common inherited disorder in Caucasian populations, with over 1400 cystic fibrosis transmembrane conductance regulator (CFTR) mutations. The type of mutations and their distributions varies widely between different countries and/or ethnic groups. Seventy Iranian cystic fibrosis patients were screened for the CFTR gene mutation using ARMS/PCR (amplification refractory mutation system) for the following mutations: F508, N1303K, G542X, 1717-1G>A, R553X, W1282X, G551D, 621+1G>T, I507 and R560T. Single strand conformation polymorphism (SSCP) analysis of exons 3, 7, 10, 11 and 17b, including both the exon/intron junctions, of the CFTR gene was performed in patients in whom no mutation could be identified on one or both CFTR genes. As a result of this screening, only three mutations were found: F508 mutation was found in 25 (17.8%) alleles, N1303K in six (4.3%) alleles and G542X in five (3.6%) alleles. Thus, a total of 3 mutations cover 25.7% of CF alleles. These finding will be used for planning future screening and appropriate genetic counseling programs in Iranian CF patients.
External Validity of TOEFL Section of Doctoral Entrance Examination in Iran: A Mixed Design Study
Goudarz Alibakhshi,Hassan Ghand Ali
Theory and Practice in Language Studies , 2011, DOI: 10.4304/tpls.1.10.1304-1310
Abstract: External (generalization) validity is one aspect of construct validity (Messick, 1996) which deals with the inferences made on the basis of the test takers’ scores on a test. External validity is of particular importance in high stake tests such as tests of English for academic/specific purposes which are used to evaluate the test takers proficiency in general English for academic purposes. This study was an attempt to investigate the generalization validity of TOEFL tests administered at Iranian universities to select Ph. D candidates. In doing so, a mixed design study was applied. The data for the quantitative part was collected through a self assessment instrument consisting of personal information and 40 items designed on five point Likert scale. 450 doctoral students from different universities in Iran took part in the study. The data of the study were analyzed through descriptive and inferential statistics including principal component analysis, univariate analysis of variance and regression analysis (p=.05) approaches. The qualitative data was analyzed through content analysis. The results of the study indicated that there is a significant difference between the participants’ mean scores on TOEFL test and their means on academic language skills. Moreover, TOEFL scores did not significantly predict the test takers’ scores on the use of academic language in target language use situations. Therefore, TOEFL test developers should take the issue of generalizability into consideration while planning TOEFL tests.
