Some of peculiarities are caused by the lack of data at the moment when engineering solutions had to be made, Other peculiarities are connected with physical peculiarities of the device behaviour. To provide the analysis of structure hehaviour under the condition of the lack of input information, two types of design models of seismic protection devices were considered. They are the dampers linearization and the modelling of real dampers by dry friction ones. The dampers linearization makes it possible to use the existing software for calculating linear strongly-damped systems. To calculate structures with dry friction dampers, a new software was worked out. In this case, the structure is described as a piecewise-linear system of a relay-type. The investigations of the structure oscillations take into account both horizontal and vertical components of earthquake input. Under this condition, horizontal oscillation equations of structures are the MaRie-Hill ones. The input and structure parameters which caused the structure instability are estimated. To exclude the structure instability, high damping devices should be used. These methods were used for seismic resistant analysis of bridges with spherical bearings and hydraulic dampers applied in Sochi.展开更多

Even whether it is preventable, most of the time, there are still very few projects or actions of the local authorities and/or organisations in Romania, due to the lack of information and resources. The suicide prevention line for children and teenagers in Bucharest is presented and evaluated after five years of activity. It may be considered as one example of good practice, since it managed to put together local knowledge, human resources, and social actors. The suicide prevention line for children and teenagers in Bucharest has been established in 2009 by the General Directorate of Social Welfare of Bucharest Municipality, in partnership with the Psychiatric Hospital "Prof. dr. Alexandru Obregia". The finances are provided by the Welfare Department, the location belongs to the Psychiatric Hospital, and the mental health services are coordinated by a neuro-psychiatrist. There are about 30 volunteers taking the phone calls 24/7. Since 2011, they established the Association of Suicidology.展开更多

During the inter-war period, this ethnic community started the process of self-configuration and we intend to emphasize the role of education and culture for identity shaping. This paper will present cultural politics in Dobrogea, especially the role of the Muslim Seminary in Babadag/Medgidia in preserving the religion, language, and the cultural heritage of the Tatar community in Romania.展开更多

"Birra Peja" brewery, Peja, Kosovo, this study did an evaluation of beer produced using six different malts. Four of the six studied malts were produced in four European countries: Ukraine, Croatia, Serbia and Kosovo; and, the other two malts were obtained from two (2) 30:70 proportion mixtures: one from Kosovo and Ukraine and another one from Kosovo and Croatia. Chemical, microbiological, sensory and tasting analyses were carried on beers produced by these malts. The study included three working groups from: "Birra Peja"; the Agricultural University of Tirana, Albania and "Union Brewery", Ljubljana, Slovenia. Chemical and microbiological tests were based on methods under the EBC (European Beer Convention) and MEBAK (Mitteleurop^iische Brautechnische Analysenkommision e.V.) guidelines. The analyses and assessments made for the quality of beer have come to the conclusion that beer produced by Croatian origin malt corresponds to a better quality beer.展开更多

The authors prescribe a Dirichlet condition on the exterior boundary and a nonhomogeneous nonlinear Robin condition on the boundary of the holes. The main difficulty, when passing to the limit, is that the solution of the problems converges neither strongly in L^2(Ω) nor almost everywhere in Ω. A new convergence result involving nonlinear functions provides suitable weak convergence results which permit passing to the limit without using any extension operator.Consequently, using a corrector result proved in [Chourabi, I. and Donato, P., Homogenization and correctors of a class of elliptic problems in perforated domains, Asymptotic Analysis, 92(1), 2015, 1–43, DOI: 10.3233/ASY-151288], the authors describe the limit problem, presenting a limit nonlinearity which is different for the two cases, that of a Neumann datum with a nonzero average and with a zero average.展开更多
