Through a series of clinical studies, this thesis aims to clarify the contribution of donation after cardiac death (DCD) to the deceased donor (DD) pool and results of kidney and liver transplantation coming from this donor source in Liège and Belgium. Additionally, an adapted DCD Maastricht classification is also discussed. Chapters 2.1 and 2.2 summarize the DCD procurement and transplant activity in Liège and Belgium from 2000 to 2009 with an update on data up to 2011. In Liège, DCD really contributes to the DD pool and boosts the transplant activity of the center in both kidneys and livers by on average 30%. By contrast, the steady rise in DCD activity in Belgium does not lead to major increase in the DD donation and transplantation. In other words, some kind of donor-type redistribution within the DD pool might occur. Chapters 2.2, 3.1, and 3.2 discuss the results of kidney transplantation (KT) from DCD. We demonstrate that Liège‟s experience is comparable to the national level in Belgium and does not differ from the general results in the world with regard to early graft dysfunction, medium-term graft function, graft and patient survival. The excellent results of DCD-KT are attributed to the relatively short warm and cold ischemia, favorable donor factors, and the role of hypothermic machine perfusion (in Belgian series). Chapters 4.1, and 4.2 discuss the results of liver transplantation (LT) from DCD. Liège‟s results are encouraging and apparently as good as those from donation-after-brain-death LT because of short warm and cold ischemia times. Belgian results show an increased incidence of primary non-function and ischemic cholangiopathy which is in agreement with previously published data. Chapter 5 proposes an adapted DCD Maastricht classification which maintains the original categories 1 to 4 that are now well-known and widely accepted, and adds a fifth category, so-called „DCD after euthanasia‟. Each category is divided into two or three sub-categories: sub-category A is linked to longer warm ischemia (and worse results) than sub-category B; and B versus C, respectively. In addition, sub-categories A (2A, 3A, 4A, and 5A) are mostly linked to DCD processes occurring in the ICU, which helps to understand and memorize this classification. By keeping the original skeleton of the 1995 Maastricht classification, room is left to add new sub-categories in the future, if deemed clinically relevant. [less ▲]

Considered, rightly or wrongly, as "new factories of the future", call centers generate more interest for both researchers and professionals. Their human aspects in general and their HR practices in particular is a rich field for investigations, due to the importance of their technical and social systems in their performance or their sustainability. The question of the choice of HR practices is the focus of this work devoted to the issue of HRM and work organization in offshoring call centers. It is based on nine case studies representing a varied typology of Moroccan call centers sector and three typical -ideal models adopted by them (Hard, Soft or hybrid). The choice of a model or another comes, initially, from a business strategy, a targeted market segment and a given level of outsourced value-added activities. The alignment between strategy and organization of the call center operates for each model to incorporate the same operational requirements (customer-agent interactions, colleagues) and its internal labor market. This variable is the link between work organization and HR strategy adopted. Referring to an HR model or another is conditioned by the intervention of the principal who greatly influence the decisions of managers as well as decision makers. [less ▲]

In the economic and energetic context of our society, it is universally recognized that an alternative to fossil fuels and oil based product will be needed in the nearest future. A potential solution is to develop second generation biofuel and biobased product that utilizes non-food plant materials. The major component of these materials is lignocellulose, which is a complex composed by widely available biological polymers such as cellulose, hemicelluloses and lignin. This thesis is a part of this approach and is focused on a well-define part of these materials: the cellulose. The first part of this work was focused on the impact of two pretraitements (steam explosion and homogenization) on physico-chemical properties and hydrolysis yield of pure cellulose fiber. In contrast with literature, results obtained showed that moderate steam explosion treatments did not appear to improve the enzymatic hydrolysis yield of the cellulose fibers. In Parralel, a model that predicts the effect of the intensity of the steam explosion treatment in correlation with temperature and time was assessed. Links between this model and the evolution physico-chemical properties of the cellulose during pretreatment and cellulose hydrolysis yield were established In a second way, a theoretical diagram predicting the degradation of the cellulose during the steam explosion treatment was established. Regarding the homogenization, it was shown that homogenization increase significatively the cellulose hydrolysis (from 25 to 100%). Results highlights potential of this technology to be used as a pretreatment Finally, enzymatic hydrolysis step has been studied in order to improve cellulose hydrolysis and to obtain high concentrated hydrolysate. In this way, two methods based on successive addition of enzyme and substrate were assessed [less ▲]

The Late Pleistocene global extinction of many terrestrial mammal species has been a subject of intensive scientific study for over a century, yet the relative contributions of environmental changes and the global expansion of humans remain unresolved. A defining component of these extinctions is a bias toward large species, with the majority of small-mammal taxa apparently surviving into the present. Here, we investigate the population-level history of a key tundra-specialist small mammal, the collared lemming (Dicrostonyx torquatus), to explore whether events during the Late Pleistocene had a discernible effect beyond the large mammal fauna. Using ancient DNA techniques to sample across three sites in North-West Europe, we observe a dramatic reduction in genetic diversity in this species over the last 50,000 y. We further identify a series of extinction-recolonization events, indicating a previously unrecognized instability in Late Pleistocene small-mammal populations, which we link with climatic fluctuations. Our results reveal climate-associated, repeated regional extinctions in a keystone prey species across the Late Pleistocene, a pattern likely to have had an impact on the wider steppe-tundra community, and one that is concordant with environmental change as a major force in structuring Late Pleistocene biodiversity.
