The main roles of the side reactions which are created by a body under the effect of an action, is to transmit the effect of the action to all parts of the body and to control the path of the body to follow the line of the action. In this research we show that, the side reactions interfere with the bounding forces between the components of the matter in the body such that, the result is a group of forces that can be called the moving body's forces, or in other words, the interference converts the body to a source of forces that act in the all directions spread out from the body's center of mass. The main role of the moving body's forces is to protect the body from the side effects, but they can be used practically to affect the body itself or anybody without any change in the body's state of motion such that, the conservation of energy law can be violated. Applications show that , if a body is moving under the effect of an action , the instantaneous value of any of its moving body's forces in its direction will not be less than the value of the action whatever the body is state of motion . The values and the roles of the side reactions, and the moving body's forces are stated as the theory of motion.
The theory of motion says that, a body under the effect of an action is converted to a source of independent forces (the moving body's forces) that act in the all directions spread out from the body's centre of mass. The main role of the moving body's forces is to prevent the body from the side effects without affecting the body's state of motion, in this case, any moving body can be seen as a natural energy multiplier. For practical purposes, the motion of the body must be controlled by a system to use at least one of its forces to affect the moving body itself or anybody, but this system must be constructed due to the characteristics of the moving body's forces to get an artificial energy multiplier. In this research we show that, the moving body's forces are used in a curvilinear motion to provide the required centripetal force. That means, the inclined plane in curvilinear motion can be seen as the most simple artificial energy multiplier. The multifunction artificial energy multiplier is a mechanical system in all its parts, designed to use the moving body's forces to do work on anybody without affecting the moving body's state of motion. The power of the energy multiplier is infinite when it is used in its ideal case, and it can increase the performance of any machine that generates mechanical power.

Having a disabled child causes stress for parents and other members of the family. In this process, siblings of the disabled child should be considered as well as parents. It is a difficult situation for a child to have a disabled sibling. Knowing thoughts, emotions and relations of siblings of disabled child provide a perspective about supporting siblings. Consequently, academic studies about children with disabled sibling come into prominence. In the current study, it is aimed to review results of a few studies about children with disabled sibling in Turkey and to reveal a perspective. It is seen that studies generally have focused on self-esteem, academic success, relation with siblings, attitudes, behaviors, experienced problems, ect. There are too few studies about intervention or support program for siblings of disabled children. Studies have revealed the problems and level of self-esteem or anxiety or relationships, but studies also must suggest support programs for children with disabled sibling to cope with these problems.
Mental model representation using fuzzy graphs have recently grown in popularity for decision support and knowledge representation. Finding the most important node in the model has multiple applications. This paper presents a new model for static analysis in fuzzy graphs applied to the learning process. It makes use WA operators for the aggregation of the different centrality measures. This composite measure make possible to order the nodes and select the most important in a more integral way. WA operator brings flexibility to the model. A case study to show the applicability of the proposal is presented.

During periods of crisis, consumers have a high tendency to change their usual purchasing behavior given the financial problems associated with the economic crisis. Consumers are becoming more and more selective and focuses exclusively on what they believe are needed for their own survival.
Through this contribution, we attempted to develop a theoretical framework around the changes made by consumers in their behaviors during and after the economic crisis. The Information collected can be useful to the theoreticians in the field of marketing, as well as to companies who want to adjust to the new markets.
The aim of this article is to understand alliances in order to reduce the risks of their fail. Thus, understanding the governance of alliances can provide critical insights into how such ties can be better managed: we focus on the coordination-cooperation relationship.
The first part of this article, we will give a theoretical back ground about cooperation and coordination. A conceptual framework of the coordination/cooperation process is developed. Then, based on action research of alliances projects, we explain a part of strategic alliance management thanks to our management of an alliance project of 14 partners from 7 countries. In order to maximize our comprehension, we realize surveys and interviews. This study high lightens the existence of a process coordination-cooperation which is sequenced and cycled that allows achieving objectives of strategic alliance and also partners objectives.
For improving the performance and the success of the alliance project, it is necessary that the coordination-cooperation process go through different strategic level of different partners engaged in the alliance project.
This review article set out of the parameters used in the evaluation of the biotic integrity of the aquatic resources based on the pisciculturals communities and the sequences of the stages to follow for the calculation and the interpretation of this index.
In the search of information about these parameters and the sequences of the stages to follow for the calculation and the interpretation of this index, several published scientific works and the published books were consulted and their synthesis was made. The review of research results revealed that the IBPI in Africa integrates sixteen parameters. Four reflect wealth and the specific composition, seven wealth relative taxonomic, and five, abundance relative trophic of fish. Every parameter takes a score in function some perturbation and their sum gives a total score for the sampled station and permits to assign him a class of integrity.
The IBPI trusts several variables or parameters and their criteria of quotation measuring different aspects of the structure and the function of the ichthyologic communities that appear, on the whole, to answer changes of weak amplitude as well as to modifications more important of the ecosystem, susceptible to give better account of the level of quality or deterioration of these ecosystems and of their capacity to maintain the balance of their biocenosis.
The main purpose of this paper was to present a causal mechanism that would explain the phenomenon behind dropout among primary students. Using a Time Series design, the study analysed a nine-year series of multivariate data using advanced methodological methods such as factorial analysis, regression analysis, anomalous detection and path analysis the study specifically tried to identify relationships among and the variables and determine which factors are directly or indirectly linked to dropout. Results of the analyses showed that child labor was the strongest determinant of dropout while indirect factors were primary completion, enrolment, employment and government expenditure. Although GDP was not found to be a strong factor it appeared to have a direct impact on the other variables that influenced dropout. This may therefore imply that low economy could be the unseen phantom behind dropout radiating to an array of other factors. Child labor may just be an outward manifestation of a serious economic problem which, if not resolved could lead more children to the periphery; joining the ranks of child labor instead of learning inside the classroom.
In Burkina Faso, the food post- harvest conservation remains a major constraint. A survey to understand farmers' perceptions of post-harvest conservation of cowpea and Bambara groundnut was carried out in nine villages of Hauts-Bassins. This survey was followed by an evaluation of samples taken from stocks of these legumes. The results show that farmers retain their crops of Bambara groundnut and cowpea at home in bags, sealed and unsealed devices. The use of traditional methods is the most widespread. According to farmers, the insects are responsible for the essential of post-harvest losses of legumes. Laboratory analysis of the samples collected, helped to identify six (6) insect species distributed in the orders of Coleoptera and Hymenoptera. Callosobruchus maculatus Fab. and Callosobruchus subinnotatus Pic. are the most abundant species.
Knowledge of post-harvest strategies in a traditional rural environment is an essential prerequisite for the development of methods and structures for effective protection of stored products. Such knowledge opens the way for the definition of methods for detection of infestations and loss estimation, the recommendation of rational methods of control, preventive as well as curative.
