We present a fully validated HPLC-UV assay for the concurrent quantification of ketoglutaric acid and hydroxymethylfurfural, a ‘targeted therapy’ composition inducing a synergistic metabolic distress to the tumoral microenvironment. The analytes were exclusively extracted from the biomatrix via a combined-cartridge solid phase extraction assembly. The method is based on derivatizing both analytes with 2-nitrophenylhydrazine directed to their chemically divergent but commonly occurring carbonyl function. The reaction is kinetically catalyzed. Acidifying the buffered eluate post-extraction is critical for the feasibility of the reaction. The chromatographic separation is successfully accomplished on octyl columns in less than 15 min at 330 nm using 0.028% TFAA-methanol-acetonitrile (58:32:10, v/v) as eluant. The assay was validated using the concept of accuracy profile. The selectivity of the method was demonstrated in pre- and post-dosed patients from a pilot study. Quality control samples were prepared and analyzed during the routine use of the method. Life samples collected from patients enduring oesophageal and breast carcinoma with lung metastases were monitored for ketoglutarate in a trial to correlate its plasma levels with the malignancy.

The theoretical developments and the numerical applications of a time-dependent damage law is presented. This law is deduced from considerations at the micro-scale where non-planar growth of micro-cracks, following a subcritical propagation criterion, is assumed. The passage from micro-scale to macro-scale is done through an asymptotic homogenization approach. The model is built in two steps. First, the effective coefficients are calculated at the micro-scale in finite periodical cells, with respect to the micro-cracks length and their orientation. Then, a subcritical damage law is developed in order to establish the evolution of damage. As shown by numerical simulations, the developed model enables to reproduce the long-term behavior encountering relaxation and creep effects. [less ▲]

A quantization can be seen as a way to construct a differential operator with prescribed principal symbol. The map from the space of symbols to the space of differential operators is moreover required to be a linear bijection. In general, there is no natural quantization procedure, that is, spaces of symbols and of differential operators are not equivalent, if the action of local diffeomorphisms is taken into account. However, considering manifolds endowed with additional structures, one can seek for quantizations that depend on this additional structure and that are natural if the dependence with respect to the structure is taken into account. The existence of such a quantization was proved recently in a series of papers in the context of projective geometry. Here, we show that the construction of the quantization based on Cartan connections can be adapted from projective to pseudo-conformal geometry to yield the natural and conformally invariant quantization for arbitrary symbols, outside some critical situations.

The single permit is the authorization required by law in Wallonia when the project requires both planning permission and environmental permit. The single permit is remarkable administrative simplification. Indeed, one procedure is applicable mediated by the different administrations. Some problems of scope have been resolved. This procedure in effect since 2002 is a success. [less ▲]

In a first chapter, fundamental notions of kinematics and statics of continua are exposed. Constitutive loads are treated in the second chapter. In the frame of thermodynamics, with the local equilibrium hypothesis, the fundamental laws of thermoelasticity are easily obtained. The extreme cases of isothermic and adiabatic deformations are also considered and compared. The third chapter presents a somewhat unexpected application of the above theory, that is the damping due to thermoconduction. [less ▲]

The question is whether the traditional administrative law instruments, authoritarian, are best suited for environmental protection. The rational economic agent or capitalist is not naturally inclined to protect the environment. The environmental law almost always must thwart individual liberty and the pursuit of profit or comfort. Consequently, consensual and non-binding instruments are not the most naturally suited to protecting the environment. The main legal instruments of environmental law are reviewed: prohibition, authorization, non-legal action, gentlemen's agreements, contracts, tax incentives, market pollution… [less ▲]

By considering a least squares approximation of a given square integrable function f:[0,1]^n to R by a multilinear polynomial of a specified degree, we define an index which measures the overall interaction among variables of f. This definition extends the concept of Banzhaf interaction index introduced in cooperative game theory. Our approach is partly inspired from multilinear regression analysis, where interactions among the independent variables are taken into consideration. We show that this interaction index has appealing properties which naturally generalize the properties of the Banzhaf interaction index. In particular, we interpret this index as an expected value of the difference quotients of f or, under certain natural conditions on f, as an expected value of the derivatives of f. These interpretations show a strong analogy between the introduced interaction index and the overall importance index defined by Grabisch and Labreuche. Finally, we discuss a few applications of the interaction index. [less ▲]

Radiotherapy is a powerful continuously evolving effective treatment tool. Our aim is to offer the best treatments and assure security for patients and personnel. A proactive quality approach copied from the one implemented in the air transport industry has been established in our department. An Experience Feed Back Committee (EFBC) has been set up to identify, record and analyze systematically all reported precursor events. Our final objective is to test and strengthen the security of the organization and the quality of care for patients. [less ▲]

This article seeks to examine the relevance of popular culture and music in particular in the context of post-migratory multicultural societies. More precisely, we aim to demonstrate how music and musicians contribute – in specific spatial and temporal settings – to the mobilization of some migrant origin populations. The article starts with a conceptual discussion on the role of music for ethnic and migrant groups and on the role of music and musicians in electoral campaigns. Subsequently, we review the case of the 2008 US presidential campaign to show the relevance of minority artists’ productions and the political use that can be made out of it in competitive electoral contexts such as that of the United States.
