Characterization of mixing and yield stress of pretreated wheat straw slurries used for the production of biofuels through tomography technique.

Wheat straw is a low-cost feedstock for the production of biofuel. Pretreatment process is an important stage in producing biofuels since it makes the fibers more accessible to enzymatic hydrolysis which is the final step of producing biofuels. Pretreated wheat straw (PWS) slurries are non-Newtonian fluids with yield stress.

Objectives: MAP (Mères avec pouvoir, or in English, Mothers with Power) is a program that proposes a comprehensive approach to promote the social and vocational integration of low income single mothers with children under six years old. Using the results of a qualitative evaluation of the program’s outcomes and the contextual factors that produced the outcomes, this article aims to identify the aspects of the program that are most promising for practise.

Method: To assess the program outcomes, the study used two monitoring tools and an information sheet on each participant.

Objectives: The initiative relies on collaboration between child protection and hospital-based social workers to help substance-abusing expectant mothers maximize their chances of caring for their newborn. The article describes the positive outcomes of this initiative for the women, based on the experiences and perception of the participants and social workers involved.

Method: A case study was conducted with twenty-one participants using three data sources: 1) a semi-structured interview with the mothers at two points in time; 2) a semi-structured interview with social workers; and 3) the tools of the initiative.

Objectives: Over the past twenty years, numerous community social pediatrics centres (CSPCs) have been established in Quebec. Because the needs of the children followed are so complex, collaboration with organizations in social services and public and community health networks is paramount. The purpose of this study is to document CSPCs’level of integration into these networks and the issues and challenges involved in such collaborations.

Fabrication and characterization of novel biomimetic PLLA/cellulose/hydroxyapatite nanocomposite for bone repair applications.

The purpose of this research is to develop and characterize a novel biomimetic nanocomposite that closely mimics the properties of real bone such as morphology, composition and mechanical characteristics. This novel porous nanocomposite is composed of cotton-sourced cellulose microcrystals, hydroxyapatite nanoparticles and poly l-lactide acid. A unique combination of commonly used fabrication procedures has been developed including pre-treatment of particles using a coupling agent.
