Understanding heat and mass transfers in porous materials is crucial in many areas of scientific research. Mathematical models have constantly evolved, their differences lying mainly in the choice of the driving potentials used to describe moisture flows, as well as in the complexity of characterizing the physical phenomena involved. Models developed in the field of Building Physics (HAM models) are used to describe the behavior of envelope parts and assess their impact on user comfort and energy performance. The water balance equation can be described in many ways; it is a function of the boundary conditions considered and the fact they induce high or low water content in the porous materials used. This paper gives an overview of various formulations for this equation that are found in the Building Physics literature. It focuses first on the physically based formulation of moisture balance, drawing on the Representative Elementary Volume (REV) concept, coupled with thermodynamic flow rates description. This is then reformulated in line with various main moisture state variables offering a wide variety of expressions that are compared with available models. This approach provides access to all secondary transport coefficients associated with the process of mathematical transformation. Particular emphasis is placed on the moisture storage function choice and its impact on the final mathematical formulations. [less ▲]

Proteins are complex macromolecules that evolved over billions of years to be active in aqueous solution. Water is a key element that stabilizes their structure, and most structural studies on proteins have thus been carried out in aqueous environment. However, recent experimental approaches have opened the possibility to gain structural information on proteins from gas-phase measurements. The obtained results revealed significant structural memory in proteins when transferred from water to the gas phase. However, after several years of experimental and theoretical research, the nature of the structural changes induced by vaporization, the exact characteristics of proteins in the gas phase, and the physicochemical forces stabilizing dehydrated proteins are still unclear. We will review here these issues using both experimental and theoretical sources of information. [less ▲]

Novarina entretient avec la philosophie une relation faite d’attraction et de défiance. Le primat accordé à la parole et le refus de toute ontologie le conduisent à définir un nouveau modèle théorique, celui de la « fugue » et, tout en poursuivant le dialogue avec les philosophes, à construire ce que nous appellerons une dialectique de l’inattendu, mouvement par lequel le vide actif qui habite la personne humaine nourrit le renouvellement de la pensée et de l’action.

The main objective of this document is to establish if the UE can be considered as an actor of the Latin-American regional integration. The method of the current research is qualitative. The different aspects of the interregional European strategy for regional integration towards Latin America (E.I.S.R.I. – L.A.) are analyzed as follows. First, the discourse that places regional integration as one of the priorities of the given strategy is studied. Second, the economic actions responsible of materializing that priority are checked. Third, the political actions of the E.I.S.R.I. – L.A. are introduced. The results of the analysis make it evident that although EU appears to be an actor of the Latin-American regional integration, its influence seems to be restricted. Nevertheless, this affirmation should be relativized because this lack of influence can be due to an absence of mechanisms of measurement of results in terms of regional integration. [less ▲]

According to the dual-process recognition models, the retrieval of information from long-term memory is supported by recollection and familiarity. Alzheimer’s disease is consistently found to affect recollection. As for familiarity, however, no consensus has been reached so far. Some studies are in favor of an early impairment of familiarity, while others are in favor of a preservation of familiarity in the mild and moderate stages of the disease. This lack of consensus can be partly explained by methodological differences between studies. We discuss three methodological dimensions: the type of recognition test, the type of paradigm for estimating familiarity and recollection, and the nature of the material used. These differences reveal the complex nature of familiarity which would be underlied by different mechanisms that may be selectively altered or preserved in the disease. [less ▲]

BACKGROUND: Bone-specific alkaline phosphatase (BAP) is now recommended to assess bone turnover in hemodialysis (HD) patients. However, little is known about potential variability between methods available to measure BAP. METHODS: We measured BAP in 76 HD patients with six different assays (Beckman-Coulter Ostase IRMA, Beckman-Coulter Ostase Access, IDS iSYS Ostase, IDS Ostase enzyme immunoassay, DiaSorin Liaison Ostase and Quidel MicroVue BAP). RESULTS: We observed a high correlation between all the assays ranging from 0.9948 (IDS iSYS vs. IDS EIA) to 0.9215 (DiaSorin Liaison vs. Quidel MicroVue). However, using the regression equations, the equivalent concentration of a Beckman-Coulter Access value of 10μg/L can range from 7.7 to 14.4μg/L and of 20μg/L can range from 16.9 to 27.9μg/L with other assays. According to Beckman-Coulter Access, 13%, 50% and 37% of the patients presented BAP values ≤10, between 10 and 20 and ≥20μg/L, respectively. Discrepancies are observed when other assays are used (concordance from 10 to 100%). CONCLUSIONS: Analytical problems leading to inter-method variation should be overcome to improve the usefulness of this marker in clinical practice. According to correlation results, recalibration of BAP assays is necessary but should not be a major issue. [less ▲]
