    The electrical properties of wollastonite inlaid NR/SBR type elastomer based material have been evaluated. Electrical properties of the samples were measured in the temperature range of 303 to 453 K and the frequency range of 100 Hz – 40 MHz. All electrically measured parameters were given anomalies at 385 K. Only one type of dielectric relaxation process have been observed for all measurements. Physical parameters characterizing the dielectric behavior have been obtained by fitting the experimental results in the modified Debye equation. The activation energy which is thermally activated by dielectric relaxation process have been calculated to be 0.58 eV. DC conductivity increasing by temperature has been explained with the help of VFT model whereas the AC one has been clarified by the OLPT model

    Therapeutic Options for the Treatment of Hypertension in Children and Adolescents

    Primary hypertension in children is increasing in prevalence with many cases likely going undiagnosed. The prevalence is currently estimated at between 3%–5% in the United States and may be higher in certain ethnic groups. Primary hypertension, once felt to be rare in children, is now considered to be about five times more common than secondary hypertension. This review provides information to guide physicians through an organized approach to: 1) screening children and adolescents for hypertension during routine visits; 2) using normative percentile data for diagnosis and classification; 3) performing a clinical evaluation to identify the presence of co-morbidities; 4) initiating a plan of care including subsequent follow-up blood pressure measurements, therapeutic lifestyle changes and pharmacologic therapies

    Diagnostic accuracy of a clinical diagnosis of idiopathic pulmonary fibrosis: An international case-cohort study

    We conducted an international study of idiopathic pulmonary fibrosis (IPF) diagnosis among a large group of physicians and compared their diagnostic performance to a panel of IPF experts. A total of 1141 respiratory physicians and 34 IPF experts participated. Participants evaluated 60 cases of interstitial lung disease (ILD) without interdisciplinary consultation. Diagnostic agreement was measured using the weighted kappa coefficient (\u3baw). Prognostic discrimination between IPF and other ILDs was used to validate diagnostic accuracy for first-choice diagnoses of IPF and were compared using the Cindex. A total of 404 physicians completed the study. Agreement for IPF diagnosis was higher among expert physicians (\u3baw=0.65, IQR 0.53-0.72, p20 years of experience (C-index=0.72, IQR 0.0-0.73, p=0.229) and non-university hospital physicians with more than 20 years of experience, attending weekly MDT meetings (C-index=0.72, IQR 0.70-0.72, p=0.052), did not differ significantly (p=0.229 and p=0.052 respectively) from the expert panel (C-index=0.74 IQR 0.72-0.75). Experienced respiratory physicians at university-based institutions diagnose IPF with similar prognostic accuracy to IPF experts. Regular MDT meeting attendance improves the prognostic accuracy of experienced non-university practitioners to levels achieved by IPF experts

    Çalışmanın amacı Türk uluslaşma sürecinde Lozan azınlıklarının durumunu tespit etmektir. Üç bölümden oluşan tezin birinci bölümünde, ulus ve ulusçuluk Batı deneyimi çerçevesinde incelenmiştir. İkinci bölümde ise, Osmanlı İmparatorluğu'nda ulusçuluğun yaygınlaşması ve bu çerçevede gayrimüslimlerin ulusçuluk ideolojisinden etkilenme süreçleri ve Osmanlı yönetiminin gayrimüslim uluslaşmasına gösterdiği tepki irdelenmiştir. Üçüncü bölümde de, Tek Parti yönetiminin azınlıklara yönelik politikaları değerlendirilmiştir. Milli iktisat politikalarıyla ekonomik hayattan dışlanmışlardır. Eğitim ve dil politikaları ile Türkçe konuşmaları istenmiştir. Ayrıca, birtakım fiili uygulamalarla da yurttaşlık haklarından tam olarak yararlanmaları mümkün olmamıştır.Osmanlı son döneminden itibaren başlayan toplumsal ve siyasal hayattan dışlanma süreci, Tek Parti döneminin sonuna gelindiğinde azınlıkların nüfusunda büyük bir azalmaya neden olmuştur.Türk uluslaşma süreci Osmanlı son dönemi ile başlamıştır. Bu süreçte Cumhuriyet döneminde, uluslaşma konusunda radikal düzenlemelere gidilmiştir. Dolayısıyla, Türk uluslaşmasında yaşanan zorluklar bütün toplulukları etkilemiştir. Ancak, azınlıklar bu zorluklardan diğer topluluklara oranla daha çok etkilenmişlerdir.Objection of this dissertation to determine to position of the minority in the Turkish Nationalistic Process.First part of this dissertation, nation and nationalism concepts are explained in the frame of Western experience.In the second part of this study, the development of nationalistic ideology and its effects on non-muslim communities is investigated.In the third part of this dissertation, political applications of One Party Administration about minorities are explained. In this context, minorities removed from economical and social life by using some national economic policies. Education and language policies also forced them to speak Turkish. Some practical applications affected the minorities using their nationalistic rights. All this remaving proces caused minority population to decline during One Party period.Turkish nationalism period began with ending of the Ottoman Empire. In this period, some fundamental methods were used and every application affected all communities but minorities are affected from this applications more than Turkish community

    Modeling of normal-state like contribution on the pinning induced magnetostriction

    Full text link
    To describe the change of the sign of the magnetostriction at the field close to the upper critical field, Bc2, which were observed in some magnetostriction measurements carried out on the type-II superconductors, theoretical magnetostriction curves for the superconducting state were obtained considering the normal-state like contribution. The calculations were performed employing Bean, Kim, Linear, and the exponential critical state models. We have reproduced the magnetostriction curves measured by Nabialek et al. [A. Nabialek, B. Kundys, Yu Bukhantsev, A. Wisniewski, S.M. Kazakov, J. Karpinski, H. Szymczak, Supercond. Sci. Technol. 16 (2003) 707] on MgB2 superconductors and Ikuta et al. [H. Ikuta, Y. Nakayama, N. Hirota, K. Kishio, K. Kitazawa, Appl. Supercond. 1 (1993) 635] on (La1-xSrx)2CuO4 superconductors, in which was observed such sign alternation, employing the exponential model. It is evaluated that inhomogeneity of the magnetic induction across the sample volume owing to the existence of critical current causes the normal-state like contribution to the flux-pinning induced magnetostriction. © 2007 Elsevier B.V.
