در این پایان نامه، سعی گردیده که رویکردی جدید و موثر برای سنتز 14- آریل-14h- دی بنزو [a,j] زانتن ها از طریق جفت شدن چندجزئی 2- نفتول با آلدهیدها در حضورکاتالیزورهای مختلف ارائه شود. پروژه ی اول: کاتالیزور جدید [fe3o4@sio2@[hmim][hso4با تثبیت مایع یونی متیل ایمیدازولیوم هیدروژن سولفات روی سطح نانوذرات fe3o4 پوشانده شده با سیلیکا سنتز گردید و در واکنش سنتز 14- آریل-14h- دی بنزو [a,j] زانتن ها...
Education needs assessment is one of the essential components of curriculum development. In this study, we aimed to assess the educational needs of general physicians for medical ethics. We conducted a three‐stage Delphi study of general physicians’ views on important ethical issues in their practice. In the item generation stage we retrieved 45 important educational items ...
Service Oriented Architecture (SOA) has become flavor du jour for many businesses. Seemingly, almost every company has implemented, is in the midst of implementing or is seriously considering a SOA project. A critical question many organizations are facing now is – what are the critical success factors for SOA implementations? This research aims to identify a list of factors relating to SOA imp...
tion techniques, such as predictive deconvolution or Radon transforms, fail in the presence of complex structures. A technique popularized by the Delphi consortium offers an attractive alternative in 2-D because it is theoretically independent of subsurface structure and can therefore attack all surface-related multiples regardless of their complexity. The Delphi approach can be summarized by t...
Within the context of flux tube models, heavy quark fragmentation takes place through the breaking of flux tubes with the production of a (di)quarkanti(di)quark pair. It is found that the (di)quark produced are more likely to be found in an Lz = 0 state. This naturally leads to an supression of the polarization distribution parameters w3/2 and w̃1 for (D1,D ∗ 2) and (Λc1,Λ ∗ c1) production respe...
The characteristics of current society and the interest about citizenship education in the context of lifelong learning are essential for a study that aims to describe and understand the development of social and civic competence in the educational field. A Delphi study can make a proposal in which the social and civic competence is composed of 89 items organised into five areas: knowledge, ski...
The Internet changed from a pure information media to a distribution channel, challenging companies in measuring the performance of their online distribution channels. Multi-channel retailers are particularly concerned since they need to coordinate their efforts with traditional, offline retailing activities. The paper at hand presents a corresponding metrics system derived from literature and ...
During 1996 and 1997 two empirical investigations into the importance of management of technology (MOT) issues (unresolved MOT problems) were completed. In these studies more than 150 academic and industry participants @om 17 countries evaluated the importance of each MOT issue relative to the others of its study. Each stu~ used a DELPHIIssues Questionnaire methodology which involved multiple q...
Big data and its applications have increasingly received interest by both scholars and practitioners. However, there is still missing evidence regarding how big data is understood as well as its applications in supply chain management (SCM). Empirical contributions are especially limited. This study seeks to address this gap through an explorative Delphi study to understand the terminology of b...
