35-3 MARIE CURIE, O ADEVĂRATĂ LUPTĂTOARE, O URIAȘĂ PERSONALITATE A ȘTIINȚEI

Maria Salomea Skłodowska (future Marie Curie) was born on November 7, 1867, in Warsaw. His father, Wladyslaw (1832-1902), was a professor of mathematics and physics, and his mother, Bronislawa (1836-1878), was a teacher, a family lacking financial resources. Physicist Marie Curie was the pioneer of radioactivity science – the study of penetrating rays emitted by rare materials. His work has revolutionized physics and chemistry, forming the basis for further research into nuclear physics. He discovered two elements unknown until then, and he also laid the foundations for an important research institute. In 1903, she shared the Nobel Prize for Physics with her husband, Pierre, with whom she worked, and with French scientist Henri Becquerel. In 1911, Marie was awarded the Nobel Prize for Chemistry. He died in France in 1934, after a long suffering, because of a radiation-related illness. In a survey conducted among the readers of the British BBC History Magazine, Marie Curie was voted the woman with the most significant impact on the history of the world. „She (Curie) was the first woman to win a Nobel Prize in Physics, the first female professor at the University of Paris and the first person to notice the use of the word person, not a woman, who won the second Nobel Prize, said Patricia Fara, president of the British Society for the History of Science, who nominated Marie Curie.

INTERNAL AND EXTERNAL JAMS, PROPOSED SOLUTIONS CONCERNING THE IMPROVEMENT OF THE ABSORPTION CAPACITY OF THE EUROPEAN STRUCTURAL FUNDS OF ROMANIA AS A MEMBER OF THE EUROPEAN UNION. INTRODUCTION

The European Union represents a regional policy framework associated with traditional interstate and geopolitical relations. There are many institutions within the European Union, including the European Commission, which carry out economic policies regarding the financial management of European funds together with EU member countries. The absorption capacity of the structural funds was acceptable until 1.01.2019 compared to the previous years, but was marked by internal and external bottlenecks, bureaucracy and inefficiency of the institutional structures. Following the evaluation of these problems, proposals were made in this study to improve the absorption capacity of the European structural funds. The implementation of European funds has led to the spread of democratic values, the rule of law, economic and social concepts among EU member states in the context of the globalization phenomenon. Through the extension, intensification and impact of these institutional relations at the level of all the EU members in economic, social and political aspect, flows and networks are developed in the EU region of activity, interaction centers and execution of power.

35-17 JOCUL DIDACTIC- INSTRUMENT FACILITATOR AL ÎNȚELEGERII

TEACHING TOOL – FACILITATOR TOOL OF COMPREHENSION

It is interesting to note that English use two different terms for the game: „game” and „game”, which designate two different practices. „Game” refers to free games without constraints whose end is unknown, while „game” refers to situations that have a clear end (a winner, a certain achievement). The history of the game in education is complex and has its roots deep in the wings of time. Renaissance humanism has always been associated, in an innovative way, with play and learning. Gargantua, the hero of Rabelais, plays cards to learn math. In the eighteenth century, Rousseau proposes a ludic approach to learning. Subsequently, the development of sciences allowed, at the end of the nineteenth century and the beginning of the twentieth century, the development of several theories that justify the use of the game in the process of learning. The play of children will be the support of psychoanalytic activity and the therapeutic valencies will be recognized. It can only be considered an unnecessary or just recreational activity ” [1].

COMPARATIVE CURRICULAR SYSTEMS

A comparative approach to the curricula of different countries reveals the diversity of the concept of program and its evolution, both historical and geographical. However, what appears common to the various education systems and reforms implemented in various countries in recent years, is the focus on school requirements in terms of learning objectives. More and more, an approach characterized by the notion of curriculum which would replace, at least partially, that of program seems to assign objectives in terms of quality of learning and education „Inclusive” in contrast to a more traditional conception of educational programs whose content to be acquired would be a source of student selection by exclusion in case of failure.

THE THEORY OF MULTIPLE INTELLIGENCE – EDUCATIONAL IMPLICATIONS

An intelligence is a computational capacity (the ability to process a certain type of information) that is found in human biology and human psychology (H. Gardner, 2006). An intelligence involves the ability to solve or create problems that matter in a particular cultural context or in a community. The problem-solving ability allows the person to address a situation where a goal must be reached and the path best suited to achieving it must be located. The theory of multiple intelligences is formulated in light of the biological origins of each problem-solving ability. Only those skills that are universal to the human species are considered.

This paper is dedicated to those students who are in an early stage in the Noise Vibration Harshness (NVH) discipline. In this paper we study the effect of vibrations on the deformation of the rotor of a car brake disk in the event of sudden braking. Since the brake disk is often subjected to extreme conditions, in addition to vibration simulation, it has been decided that it is useful to carry out an additional study, namely a static one in which the pressure and force parameters are taken into account to see the potential deformations of the rotor. These parameters simulate the pressing of the brake pads on the surface of the rotor. The paper begins with the definition of basic terms, then presents a logical scheme of actions and finally illustrates the result of the simulations, as well as suggestions for the continuation of the study.

RESEARCH OF OPACITY AND CONSUMPTION AT DACIA SANDERO 1.5 DCI WITHOUT EGR

The study of pollutant emissions, especially of the Dacia Sandero 1.5 dCi passenger car at different operating regimes was developed by monitoring the fuel consumption. The introduction of the study is concerned about pollution, the environmental problem which is met every day. Pollution is about emitting in the surrounding environment chemical components which may lead to the structural imbalance between various life forms, which impacts health and comfort at all levels and causes ambient damage by altering natural and life sustaining factors. Different types of pollution do manifest continuously. First of all the air pollution from automobiles is the most important and analyzed in this study. In it is also considered the ecological design approach of most cars. Another section of the study makes a brief history of the internal combustion engines and their improvement process taking into account the pollutant emissions. Further in the study a comprehensive step is about the evolution of the chemical pollution. Last but not least is a description of the devices for measuring the pollutant emissions of cars. Another chapter enumerates and defines the filters, equipment and systems applied in engine development to meet increasingly stringent pollution standards. The study also contains the experimental part of the work. In this part is presented the measuring system used and then the results acquired from the Dacia Sandero 1.5 dCi engine, by monitoring the variation in the opacity of the exhaust smoke and the evolution of fuel consumption in different engine operating regimes. The last part of the study contains the final conclusions and proposed development perspectives.

The study of opacity, in particular for Dacia Sandero 1.5 dCi compression ignited engine in two distinctive operating circumstances was developed by monitoring the exhaust emission and fuel flow with and without an injector failure. The first part of the research is focused on Sandero presentation and its relation with environmental pollution. The last improvements and optimizations of the car are conducted toward the increased performance and efficiency of the car’s operation. The opacity is one of the most important pollution aspects from compression ignited engines. Its effects on the environment are great and significant. It is also analyzed the ecological and dynamic design of the studied car. The present study makes a brief analyze of the available literature on the problem of emissions and consumption. The engine’s improvement and the optimization process should take into account the pollutant emissions and the real source. Last but not least there is a study of vehicle structure, of the common-rail injection system with specific devices for the pollutant emissions control on the investigated car. The paper also presents the applied or the practical part of the research work. In this part the most interesting aspect are the experimental data acquired during the practical measurements in operation, when it is managed the data package and the graphical representation of the results from Dacia Sandero 1.5 dCi engine.

35-45 STUDIUL VIBRAȚIILOR CU SCOPUL DE A RECUPERA ENERGIE DE PE CĂILE DE RULARE ALE AUTOVEHICULELOR

STUDY OF THE VIBRATIONS IN ORDER TO HARVEST LOW-LEVEL ENERGY FROM ROADS Scientists have developed different technologies for generating electricity, but in most cases, this is achieved by using fossil fuels that can have a detrimental effect on human health and the whole ecosystem, which means global warming and changing climatic and biological balances. To avoid this, we must solve the reduction of the use of fossil fuels and find new methods of generating electricity similar to photovoltaic and wind technologies. Piezoelectric energy harvesting technology has significant advantages over other renewable energy sources such as solar or wind. Using the pressure of vehicles over the road caused by gravity, the method generates electric energy from the deformations of the paving. Although recent research projects have paid attention to this energy harvesting technology, only a few studies have been conducted on-site to determine its feasibility and economic competitiveness. No data are available about how this was realized. Therefore, it is necessary to develop a research framework that enables assessment of the technology of piezoelectric materials for this purpose.

PERSPECTIVE IMPRESSIVE ENGINEERS – Part I

Over the past 150 years technology has advanced more than ever predicted history of technology. For example, 3D prototyping / printing has become a widely-appreciated and widely used phenomenon. This is a simple and fast manufacturing process, a technique that allows engineers to overcome certain design difficulties in just a few hours, compared to a few weeks that would take traditional methods. Through this technology, engineering sciences, design and technical research are undergoing transformation and the special materials industry will open up a huge fan of possibilities. With 3D technology, an idea goes directly from the design phase to the execution phase, escalating beyond the traditional stages of product manufacturing. The paper systemizes some of the major 3D printing technologies, presenting tabular, focusing on the advantages, disadvantages and application domains of these technologies. And in Romania, the prospect of expanding the home use of 3D printers open to prosumerators (users acting both as producers and consumers). The 3D equipment maker will create the right legal framework for the commercialization of 3D technology only compatible with the processing of non-hazardous materials. The 3D printer user will be granted access to a type of 3D technology limited by software specifically designed by manufacturers for civil use. And so with the advent of this technology, a new chapter in jurisprudence will soon be written in Romania. But until then, Romania is only taking the first steps in this area.
