The lightweight concrete with bio-based products knows an interesting development in the construction field, especially as thermal insulation panels for walls in buildings. Before identifying and quantifying the basic physical characteristics of concrete made from wood, miscanthus, hemp or bamboo (acoustic and thermal properties in particular), it is necessary to optimize the composition of the product. It is clear that the final product is not unique and a compromise has to be found between insulation and mechanical properties. The long term stability as well as the reinforcement may be obtained by means of a mineralization process of the natural product: a preparation with a lime and/or cement-based material is necessary to reinforce the cohesion of the bio-based product. Optical and SEM analysis helped to clearly understand the interactions between the bio-based fibrous material and the cementitious materials, the quality of the bond and their effects on the properties of the cement-based concrete products.

The objective was to examine if IVF/ICSI repeated implantation failures (IF) or recurrent miscarriages (RM) could be related to preconceptional endometrial deregulations. IF was defined as the absence of pregnancy despite the transfer of at least ten IVF/ICSI good quality embryos, and RM as having at least three unexplained miscarriages. Fertile controls (FC) were women who had given birth at least once. Endometrial biopsy was performed in the mild luteal phase of a non-conceptual cycle (five women were selected in each group). Affymetrix chips (GeneChip Human Genome U133 Plus2.0 Array) were used for hybridization. Data were normalized by the gcRMA method, and raw p values adjusted by the Bonferroni procedure (1%). Differential expression of selected genes was analysed using real-time PCR. Gene networks and biological functions were explored using the Ingenuity Pathways Analysis software. Endometrial gene expression profiles at the time of uterine receptivity differ dramatically in the endometrium among FC, RM, and IF patients. Compared to FC, 2126 and 2477 genes are differentially expressed in IF and RM groups, respectively, and 2363 between IF and RM. In both conditions, differential gene expression referred mainly to DNA transcription and expression. Other main cellular functions deregulated in IF conditions correspond to cell morphology, cellular development, cell cycle, and cellular assembly, while in RM conditions, deregulated cellular functions relate to cell signalling (degradation of cyclic AMP and calcium metabolism) and cellular maintenance. In both conditions, there is an over-representation of deregulations related to the haematological system. In the IF condition, cell-mediated immune response and nervous system development and function are highly deregulated, while in RM patients, main deregulations are in organ and tissue development, humoral immune response, and muscular system development and function. Extensive endometrial deregulations are present before conception in patients who experienced IF or RM with both distinct and common deregulation. [less ▲]

En Guatemala, para alcanzar los Objetivos de desarrollo del Milenio se implemen- tan Programas Conjuntos con el apoyo del Sistema de Naciones Unidas. Existen en la actualidad cinco Programas Conjuntos apoyando temas de seguridad alimen- taria, construcción de la paz, cambio climático, género y gobernabilidad económi- ca del agua. En el marco del programa conjunto: “Gobernabilidad económica en agua y sanea- miento” se decidió realizar un estudio que permitiera conocer la gobernabilidad en el sector a partir de hacer un inventario de las agrupaciones usuarias de agua con fines agrícolas y conocer algunas de sus características, este estudio contó con la asesoría técnica de la Organización de las Naciones Unidas para la Agricultura y la Alimentación –FAO– y el apoyo en campo de las comunidades asociadas por el agua y el medio ambiente de la cuenca del río Naranjo –CADISNA– en coordina- ción con el Ministerio de Agricultura Ganadería y Alimentación –MAGA– y go- biernos locales. El estudio se realizó en 8 municipios, 3 del departamento de Quetzaltenango y 5 de San Marcos, se identificaron 126 grupos de riego, de ellos, 73 pudieron ser carac- terizados. Se conoció que el 92% de los 73 grupos tiene una junta directiva que vela por el funcionamiento del sistema y la producción se ve diversificada en al menos 14 diferentes hortalizas siendo la principal el cultivo de la Papa. Sin embar- go sólo el 45% paga una tarifa a su grupo y el 60% de los usuarios necesita crédito para poder producir, haciendo uso de al menos 271.99 Lts/seg de agua para fines agrícolas. [less ▲]

Hyporheic exchange is an important process that underpins stream ecosystem function, and there have been numerous ways to characterize and quantify exchange flow rates and hyporheic zone size. The most common approach, using conservative stream tracer experiments and 1-D solute transport modeling, results in oversimplified representations of the system. Here we present a new approach to quantify hyporheic exchange and the size of the hyporheic zone (HZ) using high-resolution temperature measurements and a coupled 1-D transient storage and energy balance model to simulate in-stream water temperatures. Distributed temperature sensing was used to observe in-stream water temperatures with a spatial and temporal resolution of 2 and 3 min, respectively. The hyporheic exchange coefficient (which describes the rate of exchange) and the volume of the HZ were determined to range between 0 and 2.7 × 10−3 s−1 and 0 and 0.032 m3 m−1, respectively, at a spatial resolution of 1–10 m, by simulating a time series of in-stream water temperatures along a 565 m long stretch of a small first-order stream in central Luxembourg. As opposed to conventional stream tracer tests, two advantages of this approach are that exchange parameters can be determined for any stream segment over which data have been collected and that the depth of the HZ can be estimated as well. Although the presented method was tested on a small stream, it has potential for any stream where rapid (in regard to time) temperature change of a few degrees can be obtained. [less ▲]

Depuis la parution en 1966 de L’analyse structurale du récit, l’usage que fait le discours d’information du récit a donné lieu à un très grand nombre de travaux. Emportée par ce succès, la notion de récit y subit par ailleurs un fléchissement conceptuel qui peut aller jusqu’à désigner la « super forme » implicite à laquelle les médias de masse renverraient nécessairement lorsqu’ils relaient événements ou informations. Un important ensemble de recherches ( inspirées des théories littéraires, notamment la narratologie, des recherches sur le récit « postmoderne » ou, plus récemment, du travail de Paul Ricoeur ou Michel de Certeau sur les liens entre récit et vie quotidienne), ont fait évoluer la manière dont la catégorie « récit » est susceptible de questionner le discours d’information. Cet article propose une lecture épistémologique de cette évolution, et rend compte des conditions d’émergence des enjeux actuellement questionnés dans l’étude des récits d’information. Il montre comment se sont imposées les questions liant récit, mythe et histoire collective puis, plus récemment, récit et fiction, et expose les raisons pour lesquelles, aujourd’hui, ces questions sont déportées vers une approche plus pragmatique, centrée sur la narration en tant qu’elle est un processus de médiation. L’ensemble de ces réflexions impose de clarifier une situation notionnelle parfois confuse ; l’article propose ainsi de réarticuler ensemble récit et narration en leur adjoignant la notion de récitation.

Model refinements of non-linear magnetic circuits are performed via a finite element subproblem method. A com- plete problem is split into subproblems to allow a progression from 1-D to 3-D including linear to non-linear model corrections. Its solution is then expressed as the sum of the subproblem solu- tions supported by different meshes. A convenient and robust correction procedure is proposed allowing independent overlapping meshes for both source and reaction fields. It simplifies both meshing and solving processes, and quantifies the gain given by each refinement on both local fields and global quantities. [less ▲]

Rhinosinusitis (RS) is a heterogeneous group of diseases. It is a significant and increasing health problem that affects about 15% of the population in Western countries. It has a substantial impact on patients' health-related quality of life and daily functioning and represents a huge financial burden to society and the health care system as a result of the direct and indirect costs. In addition, RS is not well-understood, and little is known about the etiology and pathophysiology. In the past decade, many papers have been published that have changed our understanding of RS. RS is commonly classified into acute and chronic RS based on symptom duration. In acute RS, an inflammatory reaction initiated by a viral infection characterizes most uncomplicated, mild to moderate cases. Therefore, the first line of treatment for these cases are intranasal steroids and not antibiotics. In severe and complicated cases, antibiotics combined with topical steroids remain the treatment of choice. On the other hand, chronic RS is actually subdivided into two distinct entities (chronic rhinosinusitis with and without polyps), as growing evidence indicates that these entities have specific inflammatory pathways and cytokine profiles. The authors review recent data regarding the clinical presentations, cytokine profiles, tissue remodeling, and modalities of treatment for each form of RS. [less ▲]

Le Burkina Faso, s’est engagé depuis plusieurs années dans le domaine de la conservation de la Nature, mais souffre du manque de moyens nécessaires pour entretenir et développer son potentiel faunique. En 1996, le Burkina Faso s’est engagé dans une réforme inédite dans ce pays visant à ouvrir la gestion de la faune au secteur privé. Cet article présente à travers l’exemple de la Zone de Chasse de Konkombouri comment le concessionnaire a pu, en mettant en œuvre un certain nombre d’aménagements et certaines activités de gestion de terrain, redynamiser la faune qui s’est multipliée par 3 en 12 ans et comment l’activité de grande chasse a pu créer une dynamique économique favorable à l’Etat, aux communautés locales et aux prestataires de services locaux et étrangers. L’analyse économique compare également les résultats économiques de la ZCK à d’autres zones de chasse d’Afrique Centrale et de l’Ouest. [less ▲]
