The Droblem of the abru~t change of the direction of a crack, DroDagating with high velocity, is studied in the resent work. The study is based on a unified ao~roach of the directional instability ~henomena, which accomDany running cracks. According to this ao~roach, the running ti^ is simulated by a reb branched configuration, consisted of two microcracks of arbitrary lengths and orientations....

This study extends prior researches by exploring the effect of organizational orientations on export performance. Building on the already extensive literature, we developed a model of relationship. A total of 120 usable questionnaires were received from the Iranian food industry SMEs. The results indicated that entrepreneurial orientation, market orientation and learning orientation positively ...

The mental health world is entering a new era. The psychoanalytic model is no longer the dominant mode of treatment. Overintellectual­ izing is quickly giving way in many of our young psychotherapists to relating with various kinds of people in developing a sense of com­ munity. This approach stresses the importance for professionals of various orientations to work together in demonstrating the...

OBJECTIVE To ascertain goal orientations of pharmacy students and establish whether associations exist between academic performance, gender, or year of study.

INTRODUCTION In many countries doctors are seeing an increasing amount of immigrant patients. The communication and relationship between such groups often needs to be improved, with the crucial factor potentially being the basic attitudes (acculturation orientations) of the doctors and patients. This study therefore explores how acculturation orientations of Canadian doctors and immigrant patie...

We describe a work-in-progress evaluating the plausibility of pedestrian orientations. While many studies have focused on creating accurate or fast crowd simulation models for populating virtual cities or other environments, little is known about how humans perceive the characteristics of generated scenes. Our initial study, reported here, consists of an evaluation based on static imagery recon...

The objective of this work is the realization of a map spatialising proposals of management and planning of lands, with a view to their rational management within the framework of a sustainable development. It was based on a diagnosis of the natural environment that allowed the analysis and identification of constraints to the development of the watershed of Ouergha (North of MOROCCO). The meth...

Electrical steels are important alloys widely used in electrical instruments. The magnetic properties and low core loss of grain oriented silicon steels are closely related to the sharpness of Goss texture ({110} ).The direction of is the softest direction for magnetism.  In this work, the microstructure and dependence of orientation density along the major texture fibers on the applied cold ro...

Why do some students avoid seeking help in the classroom when they need it? When students do not seek the help they need, they put themselves at a disadvantage for learning. We discuss how students’ personal motivational characteristics relate to their avoidance of help seeking. In particular, we discuss our work regarding perceived academic and social competence and achievementand social-goal ...
