Chlorophyll biosynthetic heterogeneity is rooted mainly in parallel divinyl (DV) and monovinyl (MV) biosynthetic routes interconnected by 4-vinyl reductases (4VRs) that convert DV tetrapyrroles to MV tetrapyrroles by conversion of the vinyl group at position 4 of the macrocycle to ethyl. What is not clear at this stage is whether the various 4VR activities are catalyzed by one enzyme of broad s...

The development of clean and renewable energy sources reflects the limited fossil resources and severe environmental problems caused by their combustion. Infinite and inexhaustible solar energy is a key resource to meet a rapidly increasing global demand for energy. Dye-sensitized solar cells (DSSC) are promising devices to generate clean energy as an alternative to the traditional solar cells ...

A numerical investigation of unsteady boundary layer flow with heat and mass transfer non-Newtonian fluid model, namely, Jeffrey subject, to the significance Soret Dufour effects is carried out by using local nonsimilarity method homotopy analysis method. An excellent agreement in results obtained both methods observed we establish a new mathematical approach obtain solutions unsteady-state phe...

For each integer $k \geq 2$, we apply gluing methods to construct sequences of minimal surfaces embedded in the round $3$-sphere. We produce two types sequences, all desingularizing collections intersecting Clifford tori. Sequences first type converge a collection $k$ tori with maximal symmetry along these circles. Near circles, after rescaling, smoothly on compact subsets Karcher-Scherk tower ...

A comparative study of the resonance Raman spectra of a number of hemoproteins with excitation in the Soret region reveals features that characterize the valence and spin state of the iron. (a) The frequency of the strongest band in the spectra for reduced (ferrous) hemoproteins always occurs between 1356 and 1361 cm-l, whereas for oxidized (ferric) proteins it occurs between 1370 and 1378 cm-l...

Through this paper, we investigated the unsteady free convection flow of a Casson fluid bounded by a moving vertical flat plate in a rotating system with convective boundary conditions. The governing equations of the flow have been solved analytically using perturbation technique. The effects of various non-dimensional governing parameters like Casson parameter, magnetic field parameter, therma...

Cet entretien avec Jean-Luc Soret, directeur de l’association Visa pour l’image – Perpignan, a objet d’évoquer l’évolution d’une structure culturelle investie dans l’éducation aux médias depuis le début son histoire. En évoquant les missions la structure, phénomène concentration local et rayonnement global ainsi que l’intégration sociale dispositifs médiation, il explicite caractéristiques d’un...
