Evaluation of Steel Element’s Strength at High Temperature (fire)
Ana-Diana Anca
Bulletin of the Polytechnic Institute of Jassy, Constructions, Architechture Section , 2006,
Abstract: In the first part of the paper there shall be considerations on the hypothesis and possibilities of assessing the fire resistance of the steel structural elements. After the critical presentation and analysis of the breaking criteria used regarding structures’ calculations at high temperatures, the way of determining the fire resistance of a metal beam stressed at pure bending is presented.
Mechanical Proprieties of Steel at High Temperatures
Ana-Diana Anca,D. Gorb?nescu
Bulletin of the Polytechnic Institute of Jassy, Constructions, Architechture Section , 2005,
Abstract: The experimental test results obtained in the study of steel mechanical proprieties variation in case of high temperatures (fire) are presented. The proprieties are referring to: Young’s modulus, E, the elastic limit, σe, and the characteristic diagram of the material (the rotation stress-strain). Theoretical laws that the model the steel behaviour at high temperature have been elaborated based on the most significant studies presented in the literature.
Theoretical Models in the Study of Temperature Effect on Steel Mechanical Properties
Ana-Diana Anca,D. Gorb?nescu
Bulletin of the Polytechnic Institute of Jassy, Constructions, Architechture Section , 2006,
Abstract: The governing laws adopted by two high qualified scientific organizations (D.T.U. and Eurocode) for the variation of steel mechanical properties at high temperatures are presented. There are no significant differences between them, but generally, the items advanced by Eurocode 3, part 1.2, are dopted in the most works that approach the thermical-mechanical analysis of steel structures.
Disaster Risk Management of Urban Systems
Ana-Diana Anca,Florin Leon,Gabriela-Maria Atanasiu
Bulletin of the Polytechnic Institute of Jassy, Constructions, Architechture Section , 2006,
Abstract: Evaluating the risk of natural disasters is an intensely debated issue, both on national and international level. In the present paper, after a brief review of the international research in this field and an introduction in risk management, we insisted on risk analysis of an urban area, called urban system. More precisely, we investigated the evaluation of risk and the behavior of the pipelines infrastructure characteristic in an urban area during an earthquake.By taking into account a certain region in Jassy city area, we present a methodology of evaluating seismic risk of the utilities network of the region. The method consists in establishing the necessary steps to be taken in such an evaluation. These steps are also graphically displayed for the gas pipelines of the area, and emphasizing the critical points existent in that sector e.g. gas stations). Using the cellular automata technique, inspired from the artificial intelligence and complex system fields, based on the GIS map of the analysed region, we obtained a map with the risk areas in case of an earthquake, taking into account the gas pipelines network and the existing critical points.
Current State of the Art for Existing Critical Systems in Urban Seismic Area
Ana-Diana Anca,Cornel Doniga,Gabriela Atanasiu
Bulletin of the Polytechnic Institute of Jassy, Constructions, Architechture Section , 2006,
Abstract: The paper is structured in three main parts. In the first part, there is a classification of the critical systems existing in the urban background, which are part of an extremely urging informational infrastructure in case of a seismic event. The critical systems are identified as those systems whose malfunction may lead to disasters affecting the human being and the environment as well. The second part focuses on the underground pipe networks, presenting at the same time, their classification into three categories of great importance in case of an earthquake, and last but not least, the final part contains the presentation of an analysis methodology of seismic behavior of the underground pipe networks, considered as part of the existing critical systems, in case of a seismic event in an urban area.
PUBLIC HEALTH SERVICES IN ROMANIA IN TERMS OF EUROPEAN POLICIES
Mariana STANCIU,Ana-Diana JAWAD
Journal of Community Positive Practices , 2013,
Abstract: The article presents several of the most serious problems concerning public health care in Romania, as seen from the perspective of some similar public policies and practices in the European space. For more than two decades the public health system of Romania has undergone a so-called reform process with the main result of the continuous deterioration of both the labour conditions within the system and the quality of the provided services. This situation was created by the severe under-financing over the long term of the reform process; the continuous decreasing of the territorial units for medical services distribution; the exodus over the borders of Romanian physicians in their search for better work conditions; and, as a consequence, the limitation of the population’s access to the public health assistance and medication. The picture of the current situation inside some nations within the European Community that have recently applied reforms in the medical area strongly contrasts with the situation within Romania. Both through adopted policies and the actual medical practices that are carried on inside Romania, Romania seems deeply dissociated from all that takes place in the European Union, in the domain of medical service delivery development. Therefore, it is no wonder that for two decades the Romanian public health system is constantly situated at the end of the rankings concerning the performance of medical services, and at the beginning of those rankings regarding the incidence of morbidity and mortality within the European Community. The article also presents the authors` vision concerning privatisation of some public medical services, the efficiency of the services delivered in Romanian hospitals, the stage of the reform and the adoption of the new health law. Within this context, there are also presented some Romanian facts and managerial practices that have kept the system in a state of dysfunction and inefficiency for a long time.

THE USE OF EXPERT SYSTEMS IN AGRICULTURAL INSURANCE. NECESSITY VS. REALITY
Moisuc Diana - Aderina,Nan Anca - Petruta
Annals of the University of Oradea : Economic Science , 2011,
Abstract: The topic was chosen due to the fact that, although agricultural insurance is particularly needed in agriculture to achieve performance, its achievements are still modest. The importance of this research is in that it tackles a very important sector of the economy, agriculture, and puts forward an immediate viable solution that meets the current needs of farmers. The contribution of the authors is their innovative solution, namely the proposition to implement expert systems in agricultural insurance, as a means of promoting insurance products which, although they are not currently granted the due importance, have started to be acknowledged increasingly in recent times. The interest in this type of insurance is due to the recent climate changes whose effects are extremely damaging, and to the need to improve agricultural competitiveness on the common market as a result of trade liberalization in agricultural products. The scientific literature in the field of expert systems highlights the benefits of implementing systems in all areas of economic and social activity, including insurance and agriculture, but it does not deal separately with the issue of agricultural insurance, despite its importance in the development of agriculture. This confirms the topicality of the study. Regarding the scientific methodology, in order to easily understand how expert systems work also by those who are not familiar with the field, we opted to present the stages of preparation of the system, namely: (a) preparing the knowledge database, (2) preparing the charts and (3) system encoding and assessment. The research results, at the conceptual level, confirm the need for agricultural insurance expert systems because of the benefits it would create (ease of use, informing farmers about the existence and importance of agricultural insurance, increasing demand for such type of insurance, which would also lead to the development of agriculture, to the creation of insurance products tailored to farmers needs) and refers to the authorities that should be appointed to implement these systems.
