For hyperspectral imaging, diffraction gratings based spectrometers exhibit high spectral resolution and optical performance. Among those spectrometers, the Offner type (which consists of an entrance slit, two concave mirrors and convex grating) offers a lot of advantages. In this paper, we propose the design and modelization of a convex grating which covers a spectral band ranging from 0.7 μm to 5 μm with a minimum diffraction efficiency of 20% at 800 nm, 50% at 3000 nm and 25% at 5000 nm. For a so wide band, a grating with a single blaze cannot satisfy these requirements. We will therefore propose an approach of multi-blaze grating which is subdivided into different sections each with its own blaze angle. On April 30, 2016 we published a similar article in your journal and the optimization process resulted in a grating design of 9 blaze wavelengths. We have continued to work on this and currently we propose a better optimization method which allows to obtain the same results but only with 3 blaze wavelengths. Meanwhile, we perform the diffraction efficiency prediction using the scalar and rigorous theories to prove the compliance of this design with the technical specifications. The rigorous theory will also allow us to study the polarization sensitivity of this grating and the calculation of the diffraction efficiency of a grating with a profile degraded by manufacturing errors to assess the impact on the diffraction efficiency and the sensitivity to polarization.

The cryosphere, which comprises a large portion of Earth's surface, is rapidly changing as a consequence of global climate change. Ice, snow, and frozen ground in the polar and alpine regions of the planet are known to directly impact atmospheric composition, which for example is observed in the large influence of ice and snow on polar boundary layer chemistry. Atmospheric inputs to the cryosphere, including aerosols, nutrients, and contaminants, are also changing in the anthropocene thus driving cryosphere-atmosphere feedbacks whose understanding is crucial for understanding future climate. Here, we present the Cryosphere and ATmospheric Chemistry initiative (CATCH) which is focused on developing new multidisciplinary research approaches studying interactions of chemistry, biology, and physics within the coupled cryosphere – atmosphere system and their sensitivity to environmental change. We identify four key science areas: (1) micro-scale processes in snow and ice, (2) the coupled cryosphere-atmosphere system, (3) cryospheric change and feedbacks, and (4) improved decisions and stakeholder engagement. To pursue these goals CATCH will foster an international, multidisciplinary research community, shed light on new research needs, support the acquisition of new knowledge, train the next generation of leading scientists, and establish interactions between the science community and society.

Disulfide bonds between cysteine residues are commonly involved in the stability of numerous peptides and proteins and are crucial for providing biological activities. In such peptides, the appropriate cysteine connectivity ensures the proper conformation allowing an efficient binding to their molecular targets. Disulfide bond connectivity characterization is still challenging and is a critical issue in the analysis of structured peptides/proteins targeting pharmaceutical or pharmacological utilizations. This study describes the development of new and fast gas-phase and in-solution electrophoretic methods coupled to mass spectrometry to characterize the cysteine connectivity of disulfide bonds. For this purpose, disulfide isomers of three peptides bearing two intramolecular disulfide bonds but different cysteine connectivity have been investigated. Capillary zone electrophoresis and ion mobility both coupled to mass spectrometry were used to perform the separation in both aqueous and gas phases, respectively. The separation efficiency of each technique has been critically evaluated and compared. Finally, theoretical calculations were performed to support and explain the experimental data based on the predicted physicochemical properties of the different peptides. [less ▲]

Les territoires périurbains apparaissent comme des espaces spécifiques en Afrique centrale notamment du fait de leur caractère hybride et complexe. La spécificité de ces espaces pousse à s’interroger sur le mode de gouvernance qui s’y installe particulièrement dans la mesure où l’Etat s’y caractérise souvent par une « présence-absence » qui en facilite l’intervention d’autres individus et/ou groupes. La thèse des services publics des territoires périurbains a eu le mérite d’avoir mis en exergue la manière dont l’Etat, en ce compris les acteurs locaux investis ou pas de l’autorité publique, produisent le territoire à travers leurs pratiques, leurs comportements et les actes qu’ils posent tous les jours. Envisagé comme espace de projection de la ville de Kinshasa pendant l’époque coloniale et même post-coloniale, le territoire périurbain de Maluku a vite déçu notamment suite à la rapide faillite des entreprises, dont principalement Sosider, qui y avaient été établis au début des années 1970. La faillite de ces entreprises a immédiatement entraîné celle des services publics qui leur avaient été corollaires, justifiant ainsi le retrait de l’Etat d’un domaine qui lui est pourtant régalien. Les acteurs locaux en reprendront cependant les commandes en inventant des mécanismes de délivrance des services publics, domaine dans lequel ils opèreront de manière assez souveraine. Ces acteurs, à un moment donné de l’histoire sociale de la cité de Maluku, ont ainsi marqué de leur empreinte le territoire qui a pris la forme et la structure que nous lui attribuons aujourd’hui.

L’agriculture irriguée, moteur économique du sous-bassin versant de la Haute-Comoé, est confrontée à de nombreux défis, à cause entre autres de la mauvaise gestion des ressources en eau de surface, qui se raréfient. L’insuffisance de communications entre les usagers a conduit parfois à des tensions perceptibles. Au regard de ce constat et face à un système national inopérant, les parties prenantes de la « Gestion Intégrée des Ressources en Eau », à travers le Comité Local de l’Eau (CLE), ont décidé de mettre en place un système de production et de partage d’informations. Une enquête qualitative réalisée pendant les campagnes sèches 2016 et 2017, a permis d’analyser le système, de repérer ses forces et faiblesses et de faire des propositions. Il ressort de cette analyse que le programme de lâchers d’eau à partir des trois principaux réservoirs contrôlant les eaux de surface, est au centre du système d’information du CLE et sa principale force réside dans la démarche de production de l’information. Le maillon « diffusion », reste cependant faible et il devrait être amélioré par des outils de communication de masse. [less ▲]

Slow freezing (SF) is the reference method for ovarian tissue cryopreservation. Vitrification (VT) constitutes an alternative but controversial method. This study compares SF and VT (open [VTo] and closed [VTc] systems) in terms of freezing damage and fertility restoration ability. In vitro analyses of C57Bl/6 SF or VTo-ovaries, immediately after thawing/warming or after culture (cult), revealed that event though follicular density was similar between all groups, nuclear density was decreased in VTo-ovaries compared to CT-ovaries (CT = 0.50 +/- 0.012, SF = 0.41 +/- 0.03 and VTo = 0.29 +/- 0.044, p < 0.01). Apoptosis was higher in VTo-cult ovaries compared to SF-cult ovaries (p < 0.001) whereas follicular Bmp15 and Amh gene expression levels were decreased in the ovaries after culture, mostly after VTo (p < 0.001). Natural mating after auto-transplantation of SF, VTo and VTc-ovaries revealed that most mice recovered their oestrous cycle. Fertility was only restored with SF and VTo ovaries (SF: 68%; VTo: 63%; VTc: 0%; p < 0.001). Mice auto-transplanted with SF and VTo-ovaries achieved the highest number of pregnancies. In conclusion, in vitro, no differences between SF and VTo were evident immediately after thawing/warming but VTo ovaries displayed alterations in apoptosis and follicular specific proteins after culture. In vivo, SF and VTo ovary auto-transplantation fully restored fertility whereas with VTc-ovary auto-transplantation no pregnancies were achieved. [less ▲]

Homogenization approaches are commonly developed in order to account for micro-structural geometrical and material properties in the framework of multiscale analyses. Although most of the approaches postulate the existence of a statistically Representative Volume Element (RVE), such representativity is not always ensured, in particular when studying the failure of composite materials, because of the existing micro-structural uncertainties. In this work we develop a stochastic multi-scale approach for unidirectional composite materials in order to predict the scatter existing at the structural behaviour. Statistical characteristics of the micro-structure are first extracted from SEM images in order to build a Stochastic Volume Elements (SVE) generator [1], allowing the extraction of probabilistic meso-scale stochastic behaviours from direct numerical simulations. Finally, a probabilistic Mean-Field-Homogenization (MFH) method is developed [2,3] such that the phase parameters of the MFH are defined as random fields identified from the stochastic homogenized behaviours obtained through the direct simulations of the SVEs. As a result, non-deterministic macro-scale behaviours can be studied, allowing to predict composite failure in a probabilistic way. [1] L. Wu, C. N. Chung, Z. Major, L. Adam, and L. Noels.
