3D_Mec is a GPL-ed application for the solution of problems related to Mechanics. It is specially well suited for the direct kinematic and dynamic simulation of general systems. Is has been used during the last 10 years as a practical complement of the “Mechanics” Bachelor Course in Mechanical Engineering at the Public University of Nabarre-Spain. The main focus of the application is teaching Classical Mechanical principles and their applications. To that end 3D_Mec is constructed over an underlying Symbolic Algebra Kernel that allows the user to express itself in a language that closely resembles that of the mechanics and its level of abstraction. Classical kinematical primitives: Point, Basis and Reference, and set of operators acting upon them; support for vector and tensors, automatic basis change, ... relieve the user from the tedious algebraic manipulations directing his focus at the concept. A set of OpenGL based graphical primitives allow to represent the system and its simulation, and to create clips from them, it also represents a valuable way to check for the validity of the defined vectors and equations. 3D_Mec can also be used as a preprocessor or postprocessor, this is accomplished exporting the defined variables and different sets of equations in the popular language MatLab [3], where the integration or a different problem can be readily made based on well formed tested equations, results can be easily imported back from files containing a temporal series of the different variables. The program is also being used successfully in this way in “Dynamics of MultiBody Systems” PhD. course.

Recent Developments

Recently, theology has garnered renewed attention in the academy. For various reasons, both theologians and some religious studies scholars have argued that theology deserves to be brought into greater dialogue with other disciplines, and some have even argued that theology ought to be taught in the public university. There are interesting arguments to be made that theology is more similar to other disciplines than might initially be supposed, and even that it is at the cutting edge of certain recent developments in scholarship more broadly. There are also, however, noteworthy barriers to incorporating theology more fully into the academy, and these may present significant challenges to inter-disciplinary dialogue and the possibility of productive exchange between theology and other areas of research.

The Impact

This work deals with a methodology to assess the influence of the spherical clearance joints in spatial multibody systems. The methodology is based on the Cartesian coordinates, being the dynamics of the joint elements modeled as impacting bodies and controlled by contact forces. The impacts and contacts are described by a continuous contact force model that accounts for geometric and mechanical characteristics of the contacting surfaces. The contact force is evaluated as function of the elastic pseudo-penetration between the impacting bodies, coupled with a nonlinear viscous-elastic factor representing the energy dissipation during the impact process. A spatial four bar mechanism is used as an illustrative example and some numerical results are presented, being the efficiency of the developed methodology discussed in the process of their presentation. The results obtained show that the inclusion of clearance joints in the modelization of spatial multibody systems significantly influences the prediction of components’ position and drastically increases the peaks in acceleration and reaction moments at the joints. Moreover, the system’s response clearly tends to be nonperiodic when a clearance joint is included in the simulation.

Material Basis

The public university education in Bacau, represented by “Vasile Alecsandri” University from Bacau has developed over the past two years not only in terms of student numbers, but as human and material resources available to them. After the number of students per teacher, public higher education from Bacau is situated on the second place after Iasi, the number of teachers representing 1% of the country. The structure by scientific degrees of teachers has improved in the last year, reaching over 36% professors and lecturers and 144 PhDs. Over 55% of the teachers are younger than 40 years. The material basis has improved both quantitatively and qualitatively by putting into use a new building, bringing an additional 27 classrooms and 11 seminar rooms and providing the conditions of modern higher education.

Reading Textbooks

This article explores the insights of inclusivism and tolerance in Islamic religious education (PAI) textbooks in Brawijaya University (UB) Malang. This article is the result of research by reading textbooks, interviewing six PAI lecturers and focus group discussions (FGD) at UB Malang in December 2018. In general, there are many material aspects in the textbooks that encourage students to be open, respect for diversity and behave tolerant of different Islamic schools of thought. This is emphasized by the PAI lecturers since UB is a public university belong to the public and because in Islam itself there are many different understandings and schools of thought. The spirit of inclusivism, cosmopolitan and tolerance is seen explicitly in PAI UB’s textbooks and becomes the vision of PAI lecturers. If there is a deviation from the book tends to be a closed ideology, intolerant, and against the Republic of Indonesia, then it can be ascertained because of the “lecturer initiative” personally, and do not represent Lembaga Pusat Pembinaan Agama (the Central Institution of Religious Development).

OBJECTIVE: The main objective of this wok is the exploration of two preponderant dimensions of professional training. MATERIAL AND METHOD: An experimental study was carried out with a non-probabilistic selection of 300 students, considering their insertion in professional practices and social service in organizations allied with the public university. RESULTS: A dual structure of norms and values found with eight indicators explain the formation of job expectations in future professionals. CONCLUSION: The design limited the findings to the research scenario, suggesting the inclusion of other factors as well as the comparison of the model in other vocational training contexts such as the companies that participate in government subsidies to promote the first job in young graduates.

New Meanings

For those of us who have been going through the public university for decades, a clear tendency in most of our institutions to rethink their senses, their missions, their functions, in sum: their must be. In these times and these contexts in which deep inequalities are made visible with absolute clarity, these tendencies to construct new meanings acquire a particular relevance. We understand that public universities in the exercise of their autonomy and as members of the State, must assume a leading role with a contribution that contributes to guaranteeing rights, in particular, of the subalternized sectors. This critical positioning is inescapable to consolidate the social commitment of our higher education institutios. This compelling transformative intention has a valuable background. In this sense, we warn that both in Argentina and in some of the countries of the Region, tendencies to consolidate, systematize, institutionalize processes of emancipatory articulation in their relations with the territory, organizations and social movements have been reproduced for some years, many of them, through curricularization processes in its different meanings. These experiences, dissimilar by the way, find the need to settle, to institutionalize themselves through various conformations that in some cases converge in Educational Social Practices or similar names, with different, unique formats, but with different meanings as well. That is why we propose to display, analyze, make visible some of the salient characteristics of these processes, the regulations, their singularities, similarities, the multiplicity of their feelings, in sum, their metaphors.
