Quang Tri Old Citadel in Vietnam on the Path to Sustainable Tourism: Historical Memory as an Instrument for a Requalification Project

The aim of this study is searching and forming about the innovative solutions in preservation of the culture heritage and historical sites. The restoration of damaged heritage represents a fundamental theme in the architectural debate to provide answers at an international level. The history of civilisation reveals that the great cities of the past were destroyed by war. These destructive forces threaten the structural heritage of our great cities, putting the entire political and religious system in jeopardy. The research concentrates on the case study of Quang Tri Citadel where the culture and history experienced two wars, the French and the American one. The methodology of this study is based on the field survey, oral history, and social participation. Therefore it is appropriate to include a historical perspective in the project, assuming it unfolds on three levels within the defensive belt represents a constant and integral element of the scheme: the technical recovery of the walls, the functional transformation of the existing foundation in order to improve sociological topics, the level of architectural studies and proposals. The result of this research illustrates a new approach of the scientific debate to the cultural and historical values of the sites.DICEA, Università Politecnica delle Marche, Brecce Bianche st. 60131 Ancona IT, Doctoral School on Engineering Sciences, DICEA, Università Politecnica delle Marche, sdfdf

SU(3)_LxU(1)_N Model for Right-Handed Neutrino Neutral Currents

A model based on the \mbox{SU(3)}_L\otimes \mbox{U(1)}_N gauge group, in which neutrinos have right-handed neutral currents is considered. We argue that in order to have a result consistent with low-energy one, the right-handed neutrino component must be treated as correction instead of an equivalent spin state.Comment: 6 pages, Latex, no figures, Accepted for publication in Phys.

Comparison of separation of seed oil triglycerides containing isomeric conjugated octadecatrienoic acid moieties by reversed-phase HPLC

Relative retention analysis and increment approach were applied for the comparison of triglycerides (TGs) retention of a broad set of plant seed oils with isomeric conjugated octadecatrienoic acids (CLnA) by reversed-phase HPLC for "propanol-2-acetonitrile" mobile phases and Kromasil 100-5C18 stationary phase with diode array detection (DAD) and mass spectrometric (MS) detectio

Evaluation of a Web-based learning environment for Hands-on experimentation

The evaluation of learning environments depends highly on the evaluation instruments used and on the position of the evaluation in the design cycle. In this article, we present a use-case report of a summative evaluation of a Web-based learning environment for engineering education that allows small groups of students to conduct hands-on experimentation sessions with local and remote access to laboratory devices. This use-case illustrates an evaluation methodology based on a choice of usability engineering methods. In particular, we define specific metrics that take into account students’ interactions with some of the components of the environment. The metrics defined can easily be extended to any e-learning project involving production and sharing of artifacts in a shared workspace. The methodology is illustrated with the results of a preliminary evaluation with 30 students
