Conjoined lumbosacral nerve roots
Murat Alta?,Mustafa Aras,Boran Urfal?,Atila Y?lmaz
Dicle Medical Journal , 2012,
Abstract: Lumbosacral nerve root anomalies are a rare group ofcongenital anatomical anomalies. Various types of anomaliesof the lumbosacral nerve roots have been documentedin the available international literature. Ttheseanomalies may consist of a bifid, conjoined structure, ofa transverse course or of a characteristic anastomizedappearance. Firstly described as an incidental findingduring autopsies or surgical procedures performed forlumbar disk herniations and often asymptomatic, lumbosacralnerve root anomalies have been more frequentlydescribed in the last years due to the advances made inradiological diagnosis.

Shock and Vibration , 2014, DOI: 10.1155/2014/159213
Abstract: An efficient analytical method for vibration analysis of a Euler-Bernoulli beam on elastic foundation with elastically restrained ends has been reported. A Fourier sine series with Stoke’s transformation is used to obtain the vibration response. The general frequency determinant is developed on the basis of the analytical solution of the governing differential equation for all potential solution cases with rigid or restrained boundary conditions. Numerical analyses are performed to investigate the effects of various parameters, such as the springs at the boundaries to examine how the elastic foundation parameters affect the vibration frequencies. 1. Introduction Beams resting on elastic foundations have wide application in engineering practice. The vibration analysis of beams is investigated using various elastic foundation models, such as, Vlasov, Pasternak, and Winkler models. A number of studies have been performed to predict the dynamic response of beams on elastic foundations with different boundary conditions. Numerous works have been performed to explore the static deflection and vibration response of the beams resting on various elastic foundations. Chun [1] has investigated free vibration of hinged beam. Maurizi et al. [2] have considered the vibration frequencies for a beam with different boundary conditions. Vibration of beams on partial elastic foundations has been studied by Doyle and Pavlovic [3]. Laura et al. [4] have investigated beams which carry concentrated masses subject to an axial force. Abbas [5] has investigated vibration of Timoshenko beams with elastically restrained ends. Free vibration and stability behavior of uniform beams and columns with nonlinear elastic end rotational restraints has been considered by Rao and Naidu [6]. Free vibration behaviour of an Euler-Bernoulli beam resting on a variable Winkler foundation has been considered by Kacar et al. [7]. Civalek [8] has implemented differential quadrature and harmonic differential quadrature methods for buckling analysis of thin isotropic plates and elastic columns. H. K. Kim and M. S. Kim [9] have considered vibration of beams with generally restrained boundary conditions. A number of studies have been reported investigating the free vibration of beams on elastic foundation [10–25]. Although vibration analysis of beams on elastic foundation is a widely studied topic, there are only few papers that exist in the literature pertaining to the analysis of beams with elastically restrained ends. In this study, an efficient method is introduced for the analysis of the free
Principios para una ética de la ficción televisiva
Cuadernos del Centro de Estudios en Dise?±o y Comunicaci?3n. Ensayos , 2012,
Abstract: the overview of television fiction justified to talk about it in terms of moral perplexity and valuation. however, despite the enormous variation of approaches and perspectives on human problems that are presented on screens, almost all share the style of a high emotive commitment and a low demand of criticism.renewing a moral perspective, therefore, requires awareness of the high incidence of models on audiovisual stories to incorporate into its creation, script, editing and production, principles capable of raising the liability profile of these products. so the principles of no instrumentation, hospitality and tolerance appear as the possible ways to start improving the ethical standards of programming.
Suleymaniye: Possible Solutions for a New-Age Spirit - A Phenomenological Approach
Lerzan ARAS
Megaron , 2009,
Abstract: Along the rear of the Unkapan Dry Goods Market and extending to the Bozdo an Arches lies a residential and commercial area where shanty settlements form the ruined historical fabric. The area is too remote from the Süleymaniye Mosque to benefit from the steady tourism. Today, the promising social and architectural configuration of the area seems to be forever lost. Abject poverty in the region, whose residents are either unemployed or can barely support themselves, bears witness to the rapid downfall of the region’s historical texture. Renovation endeavors undertaken by the local government focus on changing the current social structure and revitalizing the history of the area. A group of architectural students have run pilot studies to address the questions of whether it is possible to help the current social structure adapt to the modern age and which criteria and concepts need to be considered when rebuilding the historical structure. Carrying the concepts of equality and universality to a common ground, feeling the “spirit of presence”, superpositioning different and specific identities, and creating discussion platforms of refined sensitivity comprise the core of this article.
Social marketing in healthcare
Radha Aras
Australasian Medical Journal , 2011,
Abstract: BackgroundSocial marketing is an important tool in the delivery ofhealthcare services. For any healthcare programme orproject to be successful, community/consumer participationis required. The four principles of social marketing can guidepolicymakers and healthcare providers to successfully planand implement health programmes.AimTo review the existing literature in order to project thebenefits of social marketing in healthcare.MethodA search of periodical literature by the author involvingsocial marketing and marketing concepts in health wascarried out. Items were identified initially through healthorientedindexing services such as Medline, Health STARand Cinahl, using the identifiers “social marketing“ and“marketing in health”. An extensive search was also carriedout on educational database ERIC.ResultsA literature review of various studies on social marketingindicated that the selection of the right product (accordingto the community need) at the right place, with the rightstrategy for promotion and at the right price yields goodresults. However, along with technical sustainability(product, price, promotion and place), financialsustainability, institutional sustainability and marketsustainability are conducive factors for the success of socialmarketing.ConclusionThe purpose of this literature review was to ascertain thelikely effectiveness of social marketing principles andapproaches and behaviour change communication towardshealth promotion.It is important for all healthcare workers to understand andrespond to the public’s desires and needs and routinely useconsumer research to determine how best to help thepublic to solve problems and realise aspirations. Socialmarketing can optimise public health by facilitatingrelationship-building with consumers and making their liveshealthier.

Ilham Ibrahim, Hatice Nur Aras Mehan
Open Journal of Civil Engineering (OJCE) , 2015, DOI: 10.4236/ojce.2015.54042
Abstract: During the past years different researchers have studied the causes of failure of flexible pavements and they offered variety of alternatives for solving these failure problems such as rutting, fatigue and low temperature cracking which are sourced from moisture susceptibility and also temperature sensitivity of either asphalt, aggregate or the asphalt mixture as a whole. This study is conducted to determine the optimum amount and potential applicability of zycotherm nanomaterial in asphalt and asphalt concrete mixtures with two different systems: directly applying to bitumen and diluting and applying to aggregate in order to address the solution of potential failure problems in flexible pavements. The study is carried out experimentally by conducting tests on bitumen and bituminous mixtures. Tensile strength test and retained stability tests were performed on bituminous mixture in order to measure the tensile strength ratio (TSR) and the retained stability index (RSI), which are both the indexed parameters to determine the mixture resistance to de-bonding and disintegration in the presence of water. Penetration, softening point, RTFOT, PAV, BBR and DSR tests were also performed on bitumen to determine the effect of zycotherm on bitumen’s contribution on rutting, fatigue and low temperature cracking of the mixture. It is found that using zycotherm material greatly increases the resistance of asphalt mixture to moisture induced damages and also increases its resistance to rutting, fatigue and low temperature cracking.
