Abstract:
Introduction: Thanks to the scientific publication information may be essentially known inside the scientific work and those publications are taking the primordial place in researching. It’s thanks to the publication that a performance of a high teaching facility and university is assessed. Objective: This research is aimed to scientific productions work of teachers of Lubumbashi Nursing College from March 2006 up to April 2018. Methods: We have used the descriptive and bibliographic methods. The data were collected using the questionnaire method and the documentary analysis. Out of one hundred and twenty (120) scientific and academic personals, only thirty nine (39) have fulfilled the condition required to participate research. So, in the period of twelve years, we have collected sixty eight (68) scientific productions. Outcome: We have noticed a disproportion between the number of the teachers who should produce and the number of publication that have been produced. Secondly, we’ve also noticed the irregularity of put that is out of one hundred twenty scientific teachers; we realized fourteen (14) articles which were published by the female teachers against to fifty four (54) produced by the male teachers. This is to say that in the international magazine ten (10) articles were published and fifty eight (58) were produced locally. This irregularity of publishing is due to the fact that research is able to publish unless (there is a promise of promotion) his expecting to be promoted. Otherwise, publication became sometimes non-existent. Conclusion: A teacher who is also a researcher has to publish and inform others about his researches. The work done by ISTM of Lubumbashi Teachers during the period of twelve years has produced sixty eight (68) articles for thirty mine (38) writers. Not more than half has been published. And we come to realize that writers have last the interest of publishing.
Generating Net Forces from Backgrounds of Randomly Created Waves  [PDF]
Claude Gauthier
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.516158
Abstract: We examine the possibility of generating net forces on concave isolated objects from backgrounds consisting of randomly created waves carrying momentum. This issue is examined first for waves at the surface of a liquid, and second for quantum vacuum electromagnetic waves, both in relation with a one-side-open rectangular structure whose interior embodies a large number of parallel reflecting plates. Using known results about the Casimir-like effect and the original Casimir effect for parallel plates, we explain why and how such rectangular hollow structures should feel net oriented forces. We briefly describe real systems that would allow testing these theoretical results.
Discretization and Interaction of Fields via the Classical Kaluza-Klein Theory  [PDF]
Doris LaChance, Claude Gauthier
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.412199
Abstract:

We show how the metric of a five-dimensional hyperspace-time can be used to model the quantum nature of electromagnetic interactions. The space-time neighborhood of the point where such an interaction takes place bends according to the curl and the derivative of the local electromagnetic four-potential, both calculated in the direction of the latter. In this geometric setting, the presence of a non-gravitational field is needed to induce the discretization of any gravitational field. We also exploit two variants of the classical Kaluza-Klein five-dimensional theory to obtain coupled generalizations of Einsteins and Maxwells equations. The first variant involves an unspecified scalar field that may be related to the inflaton. The equations of the second variant show a direct interdependency of gravitation and electromagnetism that would emerge or be activated through the production of electromagnetic waves.

Abstract: this paper intends to characterize the innovation process in brazilian industry, especially in what is related to the alternatives of external knowledge absorption - through machines and equipment acquisitions - and internally knowledge generation - via research and development spending. by this way, it was identified the determinants of the decisions about each of the alternatives, the level of these investments, the importance of those to innovate, besides the impact of the innovation on the firm performance. among other evidences, it was verified a larger r&d marginal productivity - in relation to the m&e acquisitions - in the brazilian industry innovation process.
A Study of DTC-Power Electronic Cascade Fed by Photovoltaic Cell-Three-Level NPC Inverter  [PDF]
Iqbal Messa?f, El-Madjid Berkouk, Nadia Saadia
Smart Grid and Renewable Energy (SGRE) , 2010, DOI: 10.4236/sgre.2010.13016
Abstract: This paper proposes a high performance three-level inverter Neutral Point Clamped (NPC) structure for photovoltaic system. The proposed configuration which can boost the low voltage of photovoltaic (PV) array, can also convert the photovoltaic DC power into high quality AC power. Attention has been paid to the problem of neutral point potential variation. In this way, a Direct Torque Control (DTC) technique has been applied and the estimated value of the Neutral Point Potential (NPP) is used, which is calculated by motor currents. This control strategy uses the redundancy presented by the inverter for selecting appropriate switching state through a switching table to achieve the control of NPP. This study shows the effect of the stability problem of the DC voltages and good static and dynamic performances were obtained in simulation of the proposed cascade “photovoltaic cell-three-level NPC VSI-induction motor”.

Hedging entry and exit decisions: activating and deactivating barrier options
Laurent Gauthier
Advances in Decision Sciences , 2002, DOI: 10.1155/s1173912602000044
Abstract: Abstract. Investment projects and businesses can be entered or exited at a cost, and the theory of real option teaches us how to find optimal activity levels that should trigger entry or exit. However, in practice, different managers or owners operate under different constraints and might apply different thresholds to the same business. We are interested in the hedging of the risk related to the cost of sub-optimal entry or exit. We introduce a new class of derivative products that can hedge this risk. The pricing of these derivatives involves the joint law of a Brownian excursion and its supremum, which is calculated thanks to Bessel processes-related distribution laws.
O que é pesquisar - entre Deleuze-Guattari e o candomblé, pensando mito, ciência, arte e culturas de resistência
Gauthier, Jacques;
Educa??o & Sociedade , 1999, DOI: 10.1590/S0101-73301999000400002
Abstract: actual science is a science of events and occurrences. after deleuze, studying the difference between event and occurrence in the stoician philosophy, the author characterises several ways to "make science": the double capture which is, in a transcultural vision, related to the god ogum in the candomblé; the dark maturation, related to the goddess oss?e etc. after spinoza, the question of the local and the universal in the construction of knowledges is examined; after michel serres, the problem of articulation between myth and science. graziela rodrigues' research, `bailarino-pesquisador-intérprete: processo de forma??o' is an example of an innovated, transcultural and social poetic approach. there's a question left to conclude this article: does the end of colonisation of spirits (and bodies) pass though the creation of a transcultural episteme?
O que é pesquisar - entre Deleuze-Guattari e o candomblé, pensando mito, ciência, arte e culturas de resistência

Educa??o & Sociedade , 1999,
Abstract: A ciência atual é uma ciência do evento e do acontecimento. Explorando, após Deleuze, a diferen a entre evento e acontecimento na filosofia estóica, o autor caracteriza vários modos de "fazer ciência": a dupla captura, referida, numa vis o transcultural, à divindade Ogum do candomblé; a matura o escura, referida à divindade Oss e etc. Daí s o discutidos, com base em Spinoza, a quest o do local e do universal na constru o do conhecimento, e com base em Michel Serres, o problema da articula o entre mito e ciência. A pesquisa de Graziela Rodrigues, "Bailarino-pesquisador-intérprete: Processo de forma o", é tomada como exemplo de abordagem inovadora, transcultural e sociopoética. Uma pergunta conclui este artigo: será que a descoloniza o dos espíritos (e dos corpos) passa pela cria o de uma episteme transcultural?
La précarité au Québec : un concept parmi d’autres pour parler des jeunes
Madeleine Gauthier
SociologieS , 2011,
Abstract: Ce texte met en contexte l’usage du concept de précarité au Québec. Celui-ci a surtout été utilisé parmi beaucoup d’autres pour décrire la situation des jeunes au moment de la crise de l’emploi des décennies 1970 et 1980. Il a parfois contribué, par son attribution à l’ensemble des jeunes, à laisser les plus vulnérables dans l’ombre et à amplifier l’effet du travail atypique sur l’avenir de toute une génération. Un usage plus modéré du concept s’est imposé progressivement en présence de faits plus justement vérifiés. Sa force de persuasion a pu susciter des stratégies tant individuelles que collectives en faveur des jeunes. Ce retour dans le temps a permis de montrer que les jeunes sont sensibles à la conjoncture mais n’en restent pas pour autant les victimes. Est-ce à cause du type d’état (de G sta Esping-Anderson, évoqué par Mircea Vultur) que le concept n’a eu qu’une importance relative au Québec ? La question se pose-t-elle dans une approche pragmatique du changement ? "Precariousness" in Québec: one of several concepts applied to young peopleThis paper examines the concept of "precariousness" in a Québec context. This concept was one of several used to describe the situation of young people during the employment crisis of the 1970s and 1980s. It was applied to young people as a whole and thus sometimes favoured a tendency to gloss over the highly vulnerable situations and to amplify the effect of non-standard employment on the future of an entire generation. More moderate use of the concept gradually prevailed with more accurate data. It was a persuasive concept that did bring about individual and collective strategies to help young people. This look backward in time shows that young people are sensitive to the economy and its performance. They are nonetheless not permanently victims of economic downturn. Is the type of welfare state (Esping-Anderson as argued by Vultur) the reason why the concept has had only relative importance in Québec? Should the question be raised as part of a pragmatic approach to change? La Precariedad en Québec: un concepto entre otros para hablar de la JuventudEste texto contextualiza la utilización del concepto de precariedad en Québec. El concepto se ha utilizado, entre otros muchos, para describir la situación de los jóvenes en el momento de la crisis del empleo de los a os 1970-1980. Por habérsele atribuido a la totalidad de los jóvenes, a veces contribuyó a dejar en la oscuridad a aquéllos más vulnerables y a amplificar los efectos del trabajo atípico sobre el futuro de una generación entera. Paulatinamente, se ha i
