A Search on Two-Electron Atoms  [PDF]
Mustafa ?apak, Bülent G?nül
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.29127
Abstract: Using the basic ingredient of two-body problem, we propose accurate algebraic solutions in a closed form for the ground state of helium and helium-like atoms. These simple but explicit expressions involve exact screening parameters for each system considered and provide an insight into their physical structure. The energy eigenvalues have been exactly calculated for atoms with nuclear charge Z in the range 1 ≤ Z ≤ 12, clarifying the relation between the screening parameteter and Z.
Education System of The Unites States of America and no Child Left Behind Act
Nezahat Gü?Lü,Mustafa BAYRAK?I
Journal of Kirsehir Education Faculty , 2004,
Abstract: Although education in the U.S.A is a responsibility which concerns local and state authorities, the roles of the Federal Government in education have started to be debated more, nowadays. The Congress prepared many programs to solve various problems in education for years, however, results of the programs and their capacities ofsupplying the local demands are neglected. It is expressed that Federal Government does not fulfill its responsibilities to reward the successful performances and to punish the unsuccessful ones. Besides, defects of the system in recent years, different practices varying from states to states, differences in performance rates have caught public’s attention to education more, therefore the government is forced to prepare a detailed reformation plan onthis issue. The name of this reformation act is “No Child Left Behind Act”. With this act, it is aimed that the differences in the success rates between states and between schools in the states, are going to be removed and also all of the children in the U.S.A. are going to be provided equal opportunities of education. In this study, the American Education System is dealt with all aspects; the principles of the new reformation and innovations which it will bringare studied.

Ayse Güne? Tan?r, Mustafa Hicabi B?lükdemir, Rasoul Ghomi
World Journal of Nuclear Science and Technology (WJNST) , 2012, DOI: 10.4236/wjnst.2012.24020
Abstract: Optically Stimulated Luminescence (OSL) trap parameters can only be reliably determined through the detailed analy- sis of OSL decay curves. In this study the kinetic parameters of a blue-light stimulated luminescence (BLS) decay curve from Al2O3:C sample irradiated at 0.1, 0.15, 0.2, 0.4 and 0.6 Gy beta doses were obtained using the same basic methods with some modifications applied and also by using our suggestion: Active-OSL Approximation (AOSL). The results were compared with those of other studies on the trap parameters of Al2O3:C material.

Abstract: The data about FFR-guided revascularization in isolated proximal LAD disease are limited and studies comparing long-term outcomes of FFR-guided PCI versus FFR-guided CABG in single-vessel proximal LAD disease are lacking. We aimed to assess the 4-year long-term safety and effectiveness of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) and FFR-guided coronary artery bypass graft surgery (CABG) for the treatment of proximal left anterior descending (LAD) lesions. The study included 129 patients with functionally significant (FFR ≤ 0.80) isolated proximal LAD stenosis (PCI, 88 patients vs. CABG, 41). Clinical endpoints were assessed by Kaplan-Meier method and compared by the log-rank test. At a mean follow-up time of 47 ± 12 months, a higher incidence of myocardial infarction in the PCI group (PCI: 32% vs. CABG: 15%; p = 0.003) and a higher incidence of stroke in the CABG group (CABG: 3 (7%) vs. PCI 0 (0%); p = 0.031) were observed. However, there were no significant differences in the primary composite endpoint, death and target vessel revascularization between PCI and CABG groups. The PCI and CABG in isolated proximal LAD lesions yielded similar long-term outcomes regarding the primary composite clinical endpoints. However, stroke was more frequent in the CABG group than in the PCI group.
Approach to small cell lung cancer

Turkish Journal of Oncology , 2007,
Abstract: Small cell lung cancer (SCLC) is distinguished by non-small cell lung cancer (NSCLC) by its’ biological behaviour, management and prognosis. As the disease is commonly in extended form and distant metastasis and regional lymph node involvement are present at the time of diagnosis SCLC is assumed as a systemic disease. Studies concerning with understanding the molecular and genetic characteristics of the disease may change the treatment modalities. Despite the efforts to develope new and effective treatment options, standart management of limited disease remained unchanged during the last fifteen years. On the other hand there are ongoing studies for the treatment of extended disease. However, prevention of cigarette smoking is still the best practice.
The Physical, Chemical and Mechanical Properties of Medlar (Mespilus germanica L.) During Physiological Maturity and Ripening Period

Journal of Agricultural Faculty of Gaziosmanpasa University , 2013, DOI: http://dx.doi.org/10.13002/jafag183
Abstract: In this study, the physical, mechanical and chemical properties of medlar during physiological maturity and ripening period were determined. The physical properties such as geometric mean diameter, sphericity, bulk and true densities, porosity, projected area and colour characteristics were measured during physiological maturity and ripening period of medlar. Mechanical properties such as rupture force, deformation and rupture energy and chemical properties (total soluble solid content, titratable acidity and pH) of medlar fruit were determined. The geometric mean diameter, sphericity, surface area and fruit density of medlar decreased, while, bulk density increased at ripening period. The fruit density of medlars increases of 10.9% occurred while bulk density and surface area decrease of 19.7% and 23.81% observed from physiological maturity to ripening period of medlar fruit, respectively. The static coefficients of friction of medlar fruit during physiological maturity and ripening period were higher for rubber than the other surfaces. The total soluble solid content and total acidity of medlar fruit decreased at ripening period.

Case Reports in Medicine , 2011, DOI: 10.1155/2011/529749
Abstract: Neuroblastoma is the most frequent extracranial solid tumor in childhood, but it is seldom diagnosed prenatally. It usually presented with adrenal masses. Presentation of other localization is extremely rare. We report a case of cervical neuroblastoma identified at 20 weeks of gestational age. This is the third case diagnosed antenatally on neck region in the literature. Additionally, it is the first case that extended to the brain. We also discussed the literature for cervical neuroblastoma detected prenatally.

Abstract: Objective: To evaluate postgraduate training period, social life and problems of cardiology residents in Turkey by using a questionnaire form and to compare with the core curriculum of European Society of Cardiology for general cardiology. Methods: Overall, 529 residents of cardiology ages in range of 24-35 years (mean age: 26.5±2.0 years, 81.4% male) participated as volunteers in this cross-sectional survey study. An 86-item questionnaire form was used to evaluate the education process, capacity of knowledge and skill and social effectiveness level of participants. The questionnaire were composed both closed- and open-ended questions. The questionnaire form was filled in with the face-to-face communication method. The data of survey were compared with the core curriculum of European Society of Cardiology for general cardiology training period. All values were expressed as mean±SD or percentage values. Chi-square or Fischer exact test was used to compare categorical variables. A p value was found significant at <0.05 level. Results: The participants were working in various university hospitals (70.3%) and training-research (state) hospitals in 31 different provinces in Turkey (40.8% in Marmara region). They visited 40±10 outpatients and 10±5 hospitalized pts daily in the clinics. The 3-5 residents worked at the clinic on night shifts and mostly (89%) 8 or more night shifts per month were held in their first training years. During first three-years of training 76% of residents have performed echocardiography, 40.8%-transesophageal echocardiography and 10% - intraoperative echocardiography. The 84.3% of them evaluated exercise tests, 76.4%-Holter electrocardiography and 53.3%-tilt-table tests. The rate of residents working in coronary angiography laboratories was 54.3%. The 53.7% of residents performed coronary angiography and 64%-only in the 4th year of their training. The number of coronary angiography performance was under expected when compared with European Society of Cardiology curriculum. The 18.5% of residents were participated as assistant researcher in an international multi-center study and only 10% had an article published in national journals (4.3% published in Science Citation Index). The 30.6% considered the cardiology training period in their centers to be insufficient, whereas 37.4% found it partially sufficient and 31.9% sufficient. Only 32.9% of participants could dedicate time for social activities.Conclusion: According to the referred core curriculum of ESC for general cardiology the training of cardiology residents in non-invasive ap

Balkan Medical Journal , 2012,
Abstract: Vulvovaginitis caused by Shigella species (Shigella spp.) has rarely been reported. This paper describes two cases of prepubertal vulvovaginitis, presenting with a bloody and purulent vaginal discharge, separately caused by ampicillin-resistant Shigella flexneri and trimethoprim-sulfomethoxazole-resistant Shigella sonnei. Our conclusions are that Shigella spp. is the potential cause of vulvovaginitis in prepubertal girls in developing countries where these pathogens are endemic, and identification of the bacteria and making antibiotic susceptibility testing in these cases should not be overlooked.
