Belhadj, Mohamed. "Vers une modélisation mathématique de la filtration des globules blancs du sang." Phd thesis, Université Pierre et Marie Curie - Paris VI, 2005. http://tel.archives-ouvertes.fr/tel-00011977.
Dans la première partie, nous définissons des modèles mathématiques qui réprésentent les principaux phénomènes physiques qui entrent en jeu dans le procédé de la filtration.
La deuxième partie est dédiée à l'analyse mathématique de systèmes d'équations aux dérivées partielles modélisant le procédé de la filtration. Tout d'abord, nous considérons un système d'équations semi-linéaires de type hyperbolique-parabolique avec une diffusion anisotrope dégénérée. Nous étudions ce problème avec une théorie $L^{1}$; nous considérons en particulier l'existence et l'unicité de solutions faibles ainsi que d'autres propriétés comme le principe du maximum; puis nous établissons la limite quand la constante de réaction devient grande. Nous montrons que le système converge vers une équation non linéaire parabolique-hyperbolique qui généralise le problème de Stefan. Nous étudions également, par des techniques de l'homogénéisation, la filtration au travers de milieux poreux fibrés. Le réseau des fibres étudié est celui utilisé par M. Briane dans le cadre d'une étude sur la conduction thermique des tissus biologiques. Nous dérivons et justifions l'équation de Darcy ainsi que la forme du tenseur de perméabilité pour un tel milieu fibreux. Les résultats théoriques concernant la perméabilité sont illustrés par quelques simulations numériques. Finalement, nous considérons le cas où le diamètre des fibres tend vers zéro. En appliquant des résultats de G. Allaire à notre cas, nous justifions rigoureusement la forme du terme dominant dans les formules de perméabilité efficace utilisées en ingénierie. Ces résultats sont également confirmés par un calcul numérique direct de la perméabilité, dans lequel la petitesse du diamètre des fibres rend nécessaire le recours à des approximations de précision élevée.
La définition des méthodes numériques efficaces pour approximer la solution des modèles mathématiques est envisagée dans la troisième partie. Précisément, concernant les équations de Darcy, nous avons utilisé la méthode des éléments finis mixtes hybrides. Pour la résolution de l'équation du transport, nous avons implémenté une méthode numérique utilisant des volumes finis pour la discrétisation du terme convection/réaction associé à une approximation mixte hybride pour la discrétisation du terme dispersif.

This thesis has focused on the problems encountered during membrane plasmapheresis. These are specifically the causes of haemolysis and flux decline during membrane separations. The objective was to find what causes haemolysis in a filtering system and how the design of a module may affect the overall haemolysis. This thesis shows that haemolysis is due to the pressure gradient across the membrane and that by reducing fibber length the potential for haemolysis is reduced. The adsorption of plasma proteins onto the membrane surface was also investigated. It was shown that during steady blood flow conditions high levels of adsorption or trapping occurred and by introducing flow pulsations this level maybe minimised. A comparison between blood flow inside and outside the fibbers was made with respect to both filtration and haemolysis performances. It was found that with blood flow inside the fibbers haemolysis was lowest and filtration was highest. Having considered these factors a system of control was tested in vitro using bovine blood and flow pulsations. The system yielded a high filtration with very low haemolysis levels

This work focuses on a new class of bottlebrush polymers, synthesized on an industrial scale and used as additives in colloidal suspensions for paper coatings. The bottlebrush polymer controls the dehydration and drying of the suspensions, and leads to coatings of outstanding quality. Our aim is to model the functional role of these polymers from a fundamental perspective in relation with applicative performances. In a first part we study their physicochemical, structural and rheological properties in solution, emphasizing the specificities due to the brush architecture. In a second part we implement an original experimental setup to analyze the water retention properties brought by the polymers. In a third part we study the drying of calcium carbonate suspensions on solid substrates, which in general forms to heterogeneous patterns called “coffee-rings”. We discovered that at very low concentration, bottlebrush polymers remarkably suppress these defects. We call auto-induced Marangoni effect the new physical mechanism at work. It results from the interfacial properties of the polymers and their specific interactions with calcium carbonate particles. To conclude, we establish a link between water retention properties and drying defect inhibition. We demonstrate the generic character of our results which can be transposed to a biological suspension, blood, where these polymers could be of interest for cardiovascular disease treatment

Microfiltration is a well-documented scientific and technological domain that still requires research when targeting the specific and accurate filtration of rare elements inside a complex medium. Indeed, innovative solutions for sample filtering of complex media may hold the key to multiple health-related and environmental issues and applications. Blood is a good example of a complex medium: it contains a large quantity and variety of cells and proteins and exhibits a viscosity three to eight times greater than water and non-Newtonian behavior when flowing. Clinical applications of blood filtration require processing large volume of blood either because of the scarcity of the targeted elements (in the case of circulating tumor cell capture, clinical relevance starts at 5 CTCs/mL of blood) or because the whole circulating blood needs to be expurgated from some adverse entities (such as cell aggregates or circulating microparticles in stroke and cardiovascular diseases). Finally, the biological nature of the targeted elements may introduce variability in the targeted element size and shape, therefore bringing fluidic challenges for their retrieval within such media. Blood filtration is a process which is central in hemodialysis, cardiovascular disease monitoring, and liquid biopsy applications based on the selective capture of Circulating Tumor Cells (CTCs), among other clinical contexts. For such applications, micro and nanofabrication using methods and techniques used today in advanced semi-conductor industry, brings the ability to control with great accuracy the size of the filtering pores with respect to the size of the targeted elements that require filtration. This level of accuracy in the fabrication process opens the opportunity to retain only the targeted element driving the biological information in the case of a diagnosis application or driving the pathogenicity in the case of therapeutic applications without impairing the composition of the eluted blood. However, because a large volume of blood is processed and due to the presence of millions of white blood cells (WBC) and billions of red blood cells (RBC) per milliliter of blood, such advanced microfabricated filters are subjected to clogging due to the unwanted accumulation of material unavoidably retained among time. This drawback appeals to the development of an in-situ method capable of sensing the cell density at the surface of these filters during use, to monitor their saturation in order to clean their surface or to proceed to their replacement by fresh ones. In this context, we propose clean room microfabricated devices capable of fulfilling these requirements. The produced sensing devices combine a filtering membrane with an in situ cellular electrical detection method through interdigitated microelectrodes and impedance spectroscopy measurements. Despite using micron-scale filtering pores and microfabricated devices, we propose a specific design that enables blood filtration at a high flow rate (11.5 mL/min), which is much larger than usual microfluidic devices. Finally, we demonstrate that stable electrical measurements can be performed in whole blood at high flow rates to monitor the saturation of the filter by retained cells. Moreover, the fine analysis of the captured cells, usually entrusted to remote laboratories, could be transferred at the patient’s bedside along the sample processing if an in-situ analysis and real-time phenotyping of the collected cells through their electrical signature could be demonstrated. This aspect will be addressed through the conception and fabrication of dedicated filtering devices, thus broadening the application field of electrical sensing on a filtering membrane within a microfluidic chip
