/ Une sonde fluorimétrique benthique, la BenthoTorch (bbe) a été acquise par le pôle Onema-Irstea d'Hydroécologie des Plans d'eau pour développer un indice fonctionnel de production primaire dans les plans d'eau. Cet indice sera basé sur la dynamique de croissance du périphyton sur des substrats artificiels. Il consti…

A systematic study of angle-integrated cross sections for electron scattering from neutral oxygen is presented. The calculations cover ionization, elastic scattering and excitation of the first 21 states of oxygen with configurations 2s 1 2p 4 and 2s 2 2p 1 nl ( n =3-5, l =0-3). The sensitivity of the results is check…
Peroxidases (POXs) are the key extracellular enzymes produced by crude oil degrading microbes. Knowledge of optimum conditions for POXs activity is crucial for providing effective environment for bioremediation. In this study, physicochemical properties of POXs produced by Actinomyces israelii and Actinomyces viscosus…
Since the first experimental evidence of photoluminescence of semiconducting single-walled carbon nanotubes (SWNTs), studies have been conducted to investigate the optical properties of these nano-structures, motivated by possible applications in the fields of quantum information, biological labeling, opto-electronics…
We investigate the discretization of Darcy flow through fractured porous media on general meshes. We consider a hybrid dimensional model, invoking a complex network of planar fractures. The model accounts for matrix-fracture interactions and fractures acting either as drains or as barriers, i.e. we have to deal with p…
Environmental stress is a daily bread for organisms across many different branches of life. Very complex response mechanisms have evolved to tackle such insults. Yeast Saccharomyces cerevisiae is adapted especially well for counteracting oxidative and osmotic stress. These unfavorable conditions usually lead to inhibi…
The ground-state properties of f-electron compounds are characterized by strong interactions which lead to a plethora of exotic states. In this thesis we focused on compounds crystallizing in the tetragonal HonCoGa3n+2-type structure. Several new compounds have been synthesized from In-flux; particularly enigmatic are…

In this paper, we study the progressive collapse of 3D framed structures made of reinforced concrete after the sudden loss of a column. The structures are represented by elasto-plastic Euler Bernoulli beams with elongation-rotation failure threshold. We performed simulations using the Discrete Element Method consideri…
Electron energy loss spectroscopy (EELS) has emerged as a powerful tool for the investigation of plasmonic nanoparticles, but the interpretation of EELS results in in terms of optical quantities, such as the photonic local density of states, remains challenging. Recent work has demonstrated that under restrictive assu…

The paper describes the experience of the laboratory of radiation monitoring in the the Kirov region since 1963. The results of long-term measurements of the environmental objects are presented. Gamma background measurement and investigation of radionuclides’ content in depositions are compared as methods for radioact…

Chemists have engineered a protein so that it self-assembles with zinc ions and an organic small molecule to form the first protein-based metal-organic framework (MOF). Including proteins in MOFs could combine the biocatalytic, electron-transfer, and molecular recognition capabilities of proteins with the separation,…
The establishments of rust converters or rust transformers have always been under scrutiny. Although the main mechanism of these transformers has not yet been confirmed, but these rust convertor react with iron oxides and produced new compounds which caused to passivate the surfaces. These transformers are mostly comp…
The subject of this work is investigation of decomposition kinetics of tertiary amines N-oxides. Decomposition of tertiary amine N-oxide(s) was performed after the synthesis of two different aromatic N-oxides of tertiary amines A and B. Kinetics of decomposition was investigated in the batch reactor at different proce…
An analytical model of unsteady heat transfer in a one-dimensional harmonic crystal is presented. A nonlocal temperature is introduced as a generalization of the kinetic temperature. A closed equation determining unsteady thermal processes in terms of the nonlocal temperature is derived. For an instantaneous heat pert…
