Influence of biodegradation on the tensile and wear resistance properties of bio-derived CaCO_3/epoxy composites
Journal of Polymer Research, 2018Co-Authors: Isiaka Oluwole Oladele, Akeem Damilola Akinwekomi, Okikiola Ganiu Agbabiaka, Michael Olalekan OladejoAbstract:This research work investigated the influence of palm kernel shell-derived calcium carbonate (CaCO_3) fillers and biodegradation on the tensile and wear properties of epoxy composites. CaCO_3 fillers were obtained from pulverised charred palm kernel shell (CPKS) particles. The composites contained between 2 wt.% and 20 wt.% of CaCO_3 fillers. The samples were characterised for microstructural Examination, Phase analysis, tensile, and wear properties. The results revealed that the composite samples possessed enhanced properties compared with the neat matrix due to the presence of CaCO_3 fillers. No particle debonding was observed on the fracture surfaces of the composite samples, which suggested that a strong interface existed between the fillers and the matrix. This could be attributed to the elimination of amorphous content from the CPKS particles during the pyrolysis process, which yielded highly crystalline CaCO_3. This was strongly supported by the XRD results. Furthermore, the effect of biodegradation on the composite properties was studied on the samples interred for 90 days in natural soil. Degradation increased as the fraction of CaCO_3 fillers increased due to the microbial degradation of CaCO_3 fillers and the investigated properties deteriorated as compared with samples that were not buried. It was concluded that bio-derived CaCO_3 fillers could function as reinforcement particles in an epoxy matrix and enhance its degradation when added in large quantities to the matrix.

Pre-Examination Phase: perimeter and process description
Annales de biologie clinique, 2020Co-Authors: P Soubiran, M Annette-reisch, A SzymanowiczAbstract:This document describes the perimeter and the content of the pre-Examination Phase using a process approach, i.e. a transversal and functional description of this activity. Pre-Examination Phase progresses trough steps differently combined according to the circumstances. Each step may be described as a sub-process characterized by an objective, intrinsic elements (beginning/end, input and output elements, upstream and downstream process, actors and technical means) and specific requirements. Ten steps have been defined from customer (patient and prescriber) information to transport. This process approach of pre-Examination Phase has several advantages: exhaustiveness, customer expectations listing at each step, risk to be prevented and anticipation of potential failures. We propose a tool allowing afterwards to optimize one or the other step and to secure it using procedures and monitoring based upon indicators.

Self assesment grid for pre-Examination Phase
Annales de biologie clinique, 2020Co-Authors: J L Dhondt, P Soubiran, J P Lionne, A SzymanowiczAbstract:This document is a proposal of questionnaire for self-assessment of pre-analytical Phase referring to the different steps described in the document SG1-01. The questions are aimed at verifying that what is examined fulfills ISO 15189 standard requirements or in general tends towards client satisfaction. This questionnaire has been elaborated using 5 M risk assessment tool for exhaustiveness purpose. This document may be useful to develop internal audit grids.

Post-Examination Phase: description and management control of the process
Annales De Biologie Clinique, 2020Co-Authors: A Perrin, A Vassault, S. Maurellet-evrard, F. Doucet-populaire, A SzymanowiczAbstract:Cet article propose une description du processus post-analytique. Ce processus transforme les resultats analytiquement verifies en resultats dument valides et interpretes par les biologistes medicaux, consignes dans un compte rendu et communiques aux prescripteurs et aux patients. Son perimetre inclut les regles de traitement des echantillons apres analyse, leur conservation et leur elimination, ainsi que l’archivage des enregistrements. La Phase post-analytique est une etape cle, a l’origine de dysfonctionnements qui peuvent nuire gravement a la prise en charge des patients. Ces erreurs temoignent souvent d’une organisation insuffisamment maitrisee et de defauts de communication avec les cliniciens ou d’adaptation a leurs besoins. Des exemples d’indicateurs qualite permettant de surveiller et maitriser le fonctionnement des differents sous-processus sont proposes, ainsi qu’un modele de contrat clinico-biologique.

Post-Examination Phase: description and management control of the process
Annales de biologie clinique, 2020Co-Authors: A Perrin, A Vassault, S. Maurellet-evrard, F. Doucet-populaire, A SzymanowiczAbstract:This article defines the scope of the post-analytical process. This process transforms the results after quality control review into validated results, interpreted by authorized "medical biologists", reported and communicated to the clinicians and patients. This Phase includes the treatment of the samples after analysis, their storage and disposal and records archiving. This Phase is a key step of the Examination involved often in dysfunctions that could hardly harm the patient. These errors are usually the consequence of failing in the control of organization, lack of communication with the clinicians and defect of adaptation to their needs. Examples of quality indicators are proposed, as well as a model of clinico-biological contract.

Guidelines for the point-of-care testing post-Examination Phase management
Annales De Biologie Clinique, 2020Co-Authors: S. Penet, A Szymanowicz, I. Vuillaume, T. Nicolas, C. Houlbert, P. PernetAbstract:Selon la legislation francaise, les examens de biologie medicale delocalises (EBMD) sont a l’origine de l’unique situation ou une validation differee de resultats d’examens de biologie medicale est possible. Cet article a pour but de proposer des recommandations pour l’organisation de la Phase post-analytique des EBMD en accord avec cette reglementation et avec les exigences de la norme NF EN ISO 22870. Dans une premiere partie, l’organisation de la validation des EBMD est detaillee (depuis la prise de connaissance du resultat par le medecin jusqu’a la validation differee des resultats et leur integration dans le dossier du patient). Dans une seconde partie, les exigences portant sur le contenu et la gestion du compte rendu de resultats des EBMD sont discutees. Un modele de compte rendu d’EBMD est propose.
