This article presents design principles and practical steps for web-based Q methodology surveys. Drawing on the experience of two online studies, we discuss theoretical concerns, sort survey design, software programs, issues in researcher–participant engagement. We argue that opening to modes data collection is important capture greater diversity social perspectives geographies.

the regioselective ring opening of styrene oxide using elemental iodine and bromine in the presence of disulfides as new catalysts was studied. the conductivity titration and uv spectroscopy were used to study the interaction of iodine with these catalysts. the results indicate that disulfide 11 is efficient in polyiodide formation, and can catalyze this reaction in excellent yield and high reg...

a. Witness Professor Reyntjens (PW77) asked permission to address the Chamber. First, he advised the Chamber that he had made an error in an answer he had given yesterday and offered further explanations. Second, he advised the Chamber that he had been given documents yesterday by Counsel for Bagosora (Mr. Constant), some of which were stamped “confidential” and which he recognized as being doc...

In recent years, the use of castellated beams has increased significantly across all types structures. The beam is one several methods for reducing weight and cost steel in construction. this study, static dynamic behavior investigated via three-dimensional finite element method. primary objective study to investigate detail effect web opening shapes on displacement, stress values, free vibrati...

Abstract In this paper, a finite element (FE) analysis is carried out on beam to column welded connections with multiple hexagonal web openings. The openings are distributed along the length of which subjected cyclic loading protocol proposed by SAC and FEMA 350 (2000). This study focuses interaction from columns perforated mobilization stresses. Two parameters were addressed: distance face (S)...

an efficient and simple method for the preparation of si-imidazole-hso4 functionalized magnetic fe3o4 nanoparticles (si-im-hso4 mnps) and used as an efficient and reusable magnetic catalysts for the regioselective ring opening of epoxides under green conditions in water. this catalyst was used for the ring opening of epoxide corresponding to the thiocyanohydrins and azidohydrines. compared to t...

Single Sign-On is widely deployed in the French Education/Research community, especially CAS [1]. In addition to improving the security, it allows users to authenticate once and use several web applications, as long as the applications are proposed by their institution. New projects in France now encourage the cooperation between universities, making them share web resources (documents and appl...

In this work, we study how legislation can be published as open data using semantic web technologies. We focus on Greek legislation and show how it can be modeled using ontologies expressed in OWL and RDF, and queried using SPARQL. To demonstrate the applicability and usefulness of our approach, we develop a web application, called Nomothesia, which makes Greek legislation easily accessible to ...

Abstract—Topology optimization technique utilizes constant element densities as design parameters. Finally, optimal distribution contours of the material densities between voids (0) and solids (1) in design domain represent the determination of topology. It means that regions with element density values become occupied by solids in design domain, while there are only void phases in regions wher...
