Continuous-flow micro- and mesofluidic reactors come with inherent properties that can be advantageously utilized for expanding the horizon of synthetic organic chemistry. Accurate control over local process parameters, even under extreme conditions, inherent safety, production homogeneity and seamless scale-up are amongst the most important assets of continuous-flow chemistry. Besides, flow chemistry enables the design of efficient multistep processes with significantly reduced footprints. In this lecture, we will discuss some of the most fascinating aspects of continuous-flow micro- and mesofluidic reactors in the specific context of preparative organic chemistry. Multiple examples illustrating the development and implementation of continuous-flow multistep strategies for the synthesis of high-value added organic targets will be presented. [less ▲]

Plasma rich platelets (PRP) consist of blood plasma with a high concentration of platelets autologous constituting a huge reservoir of growthfactors. The clinical use of the PRP is widespread in various medical applications. Even it is very popular with athletes, the use of PRP intendinopathies is still scientifically discussed, particularly related to a disparity in the products called PRP. In order to optimize employment, itshould be interested in the different stages of obtaining of the PRP. In this literature review, we analyzed in particular 8 parameters that can influencethe quality of the PRP: (1) anticoagulants used to preserve the best feature of platelet; (2) centrifuge speeds used in order to extract platelets; (3)platelet concentrations and the presence of leukocytes and erythrocytes in the PRP; (4) the platelet activators for the mast of platelets and thus therelease of growth factors; (5) use of local anesthetics to achieve infiltration, in addition to these parameters, it might be interesting to analyze othervariables like: (6) employment or not of buffer to neutralize the acidity caused by anticoagulants; (7) injection under US guidance or not; and (8)volume of PRP injected to determine their influence on the healing potential.

Short abstract Based on ethnographic fieldwork conducted among Moroccan women living in Milan hinterland in Italy, this paper aims at exploring the negotiated ways of performing both cultural and social belongings through food and at pointing out how these two dimensions can diverge or overlap in practice. Long abstract Migration constitutes for human beings an opportunity – among others – to develop a reflexive gaze upon one’s own habits (Rodier 2010), food habits in the case under study. In fact, not only changes that may occur in the ways of eating, cooking and supplying of produces, but also new relationships push individuals to question their everyday practices, which are associated with specific meanings. These meanings are socially and culturally oriented and performative, since they permit to state belongings as well as to take part to differently defined groups. In order to study these dynamics, I will present some ethnographic data collected during a research among Moroccan women living in Milan hinterland in Italy, mainly focusing on the history of two of them. The description of food practices, embedded in the narration of the migration experience and its consequences, which in its turn interacts with contextual discourses around immigrants and cultural diversity, reveals unexpected strategies to take social and cultural positionings within the collectivity. The theoretical framework upon which my analysis relies consists of a praxeological approach to subjectivation (Warnier 2001) combined with the consideration of the multi-dimensionality of the self which is derived from the intersectional perspective on identity (Crenshaw 1989; Anthias 2002; Yuval-Davis 2006). Through concrete practices involving food, individuals – women in this case – define their self as a layered complex of belongings, and they do that at both social and cultural level; thus proving how these two dimensions can diverge or overlap.

The present paper analyses an anecdotic case of “copy and paste” between two manuscripts belonging to two different lines of the Zoroastrian manuscript transmission: the Pahlavi exegetical (ms. K5) and the Sanskrit exegetical (ms. K6). I have found that a lost fragment of K5 is pasted, in fact, in K6 in a context hardly comprehensible. [less ▲]

Outlier detection techniques in spatial data should allow to identify two types of outliers: global and local ones. Local outliers typically have non-spatial attributes that strongly differ from those observed on their neighbors. Detecting local outliers requires to be able to work locally, on neighborhoods, in order to take into account the spatial dependence between the statistical units under consideration, even though the outlyingness is usually measured on the non-spatial variables. Many procedures have been outlined in the literature, but their number reduces when one wants to deal with multivariate non-spatial attributes. In this paper, focus is on the multivariate context. A review of existing procedures is done. A new approach, based on a two-step improvement of an existing one, is also designed and compared with the benchmarked methods by means of examples and simulations. [less ▲]

La plupart des espèces d’ânes sauvages et domestiques est en danger d’extinction. Leur préservation nécessite la cryoconservation du sperme, des ovocytes et des embryons. L’objectif de cette étude était de mettre au point une technique de collecte in vivo et de maturation in vitro des ovocytes d’ânesses. Les ovocytes ont été collectés par ponction folliculaire transvaginale sous guide échographique, placés dans un milieu de maturation in vitro pendant 24, 30, 34 ou 38 heures puis analysés. Quatre-vingt-douze ovocytes ont été collectés dans 193 follicules (48%) avec une moyenne de 4,2 ovocytes par ânesse. Après 34 heures de maturation in vitro, 45% des ovocytes ont été matures. Pour la première fois une technique de collecte in vivo et de maturation in vitro d’ovocytes d’ânesses a été développée. Cette technique permet d’envisager la cryoconservation et la fécondation in vitro de ces ovocytes. [less ▲]

This work provides a unified treatment of arbitrary kinds of microscopic boundary conditions usually considered in the multi-scale computational homogenization method for nonlinear multi-physics problems. An efficient procedure is developed to enforce the multi-point linear constraints arising from the microscopic boundary condition either by the direct constraint elimination or by the Lagrange multiplier elimination methods. The macroscopic tangent operators are computed in an efficient way from a multiple right hand sides linear system whose left hand side matrix is the stiffness matrix of the microscopic linearized system at the converged solution. The number of vectors at the right hand side is equal to the number of the macroscopic kinematic variables used to formulate the microscopic boundary condition. As the resolution of the microscopic linearized system often follows a direct factorization procedure, the computation of the macroscopic tangent operators is then performed using this factorized matrix at a reduced computational time.

In addition to the development of a satisfactory test procedure and recommendations to improve the overall quality of concrete repair works, the authors of this proposal intend to collaborate with various representatives from public agencies and from the industry to facilitate technological transfer. Presentations will be made in conferences and workshops in North America and Europe. At the end of the project, the results shall include two MSc theses and at least two papers in major journals, such as Concrete International or ACI Materials Journal. Also, the project should provide the basis towards a standard procedure for the evaluation of superficial cohesion of concrete, in relation with surface preparation and concrete removal techniques. Finally, recommendations and specifications could be incorporated in future versions of the ACI-ICRI Manual of Concrete Repairs as well as in DOT’s specifications. [less ▲]
