Le système d’éducation québécois, comme la société qui l’entoure, se fragmente : d’abord, en fonction des facteurs sociaux traditionnels — notamment, le revenu et l’éducation des parents —, ensuite, en fonction de la multiplication de modèles socioculturels. Dans le champ de l’enseignement primaire et secondaire, la première fragmentation s’exprime par la montée de l’enseignement privé, notamment dans les centres urbains; la seconde fragmentation se manifeste, au sein du réseau public, par la multiplication et la variété des projets particuliers, conçus pour retenir des élèves de milieux favor

Abstract:
Block cave mining is a widely employed mining method around the world due to its low operating cost. One of the key factors that affects block caving mine’s productivity is fragmentation; accordingly, significant efforts have been made and are currently being made to study fragmentation processes, including the use of numerical modelling and remote sensing techniques. It is desirable to develop fragmentation models that could be used to provide reliable estimates of the range and distribution of the sizes of the rock blocks expected to be induced by caving.

Block cave mining is experiencing a global growth in importance as new large, lower grade and deeper ore bodies favouring underground mass mining methods are developed. With block caving, the rock mass fragmentation process is decisive in the design and success of the operation. The last stage of this fragmentation process known as secondary fragmentation, plays a major role in the design and success of a caving operation. Despite this, it is the least understood fragmentation stage due in part to the complex mechanisms and the numerous variables involved in this phenomenon. The broken ore den

In order to evaluate and predict the various consequences of a FCI, many researches are conducted with either corium or high melting temperature molten metal, where premixing stage evolves with an important production of steam.

Abstract:
Abstract The increase in the number of debris in orbit and the increase in the number of nano satellites in orbit leads to the need to better understand the debris likely to be generated by these nano satellites: either by explosion from an internal energy source, or by explosion following an impact by a large external debris. The aim of this research is to explore innovative fragmentation modelling solutions implemented in Impetus Afea Solver in the context of hypervelocity impacts of debris. Thus, through this work, a complete and detailed study of complex structures under hypervelocity impa

Abstract:
The steadily increasing landscape fragmentation and the reduction of permeability for wildlife are among the most negative impacts of human activity on the environment. In terms of education, theseproblems appear to be rather demanding, withthe difficulty corresponding tosecondary school standards. Considering the multiple interdisciplinary connections, the entire process cannot be sufficiently understood without a relevant amount of preliminary knowledge. Such a corpus of information is acquired especially through biology/ecology, geographyand history classes, but links to other subjects can

Abstract:
Introduction: Thrombotic thrombocytopenic purpura (TTP) is a hematological disease resulting from the ADAMTS 13 plasmatic protein deficit. It can be congenital or sporadic, and is usually autoimmune. Pathological platelet adhesion occurs, leading to microthrombi in capillary and arterial circulation, microangiopathic anemia and ischemia. The clinical picture includes thrombocytopenia, renal dysfunction, fluctuating neurological symptoms, microangiopathic hemolytic anemia, and fever. Methods: Case report of a 51-year-old male hypertensive patient, diagnosed with idiopathic thrombocytopenic purp

Abstract:
Tillage modifies soil structure, altering conditions for plant growth and transport processes through the soil. However, the resulting loose structure is unstable and susceptible to collapse due to aggregate fragmentation during wetting and drying cycles, and coalescense of moist aggregates by internal capillary forces and external compactive stresses. Presently, limited understanding of these complex processes often leads to consideration of the soil plow layer as a static porous medium. With the purpose of filling some of this knowledge gap, the objectives of this Project were to: 1) Identif

Abstract:
Microplastics are smaller than 5 micrometers (µm) and originate either from intentional manufacturing at that size (primary microplastics: personal care products, paints, glitter, etc.) or from the fragmentation of larger plastics in use or after disposal (secondary microplastics). The recent discovery of microplastics in various biological systems, including human bodies, raises critical questions about long-term effects in ecosystem health and human well-being. The exponential rise in plastic and microplastic pollution set the stage for this 2-day meeting to explore the current state of know
