Air flow in nose and sinuses is studied by means of a simple model based on the steady-state ideal fluid flow assumption and repeated use of Bernoulli’s equation. In particular, by describing flow of air drawn in through the vestibulumnasi during inspiration, we investigate how ventilation of the maxillary sinus is affected by surgical removal of part of the lateral walls of the nasal cavity close to the ostiummeatal complex. We find that, according to the model proposed, removal of tissues from this inner part of the nasal cavity may cause a decrease of the flux rate from the maxillary sinus.

ESTIMATION OF A SOURCE TERM IN A QUASI STEADY TWO-DIMENSIONA...

Comparative Transcriptomic Analysis of Salt Adaptation in Roots of Contrasting medicago truncatula Genotypes

湖北省暨武汉焊接学会成立二十五周年2005年焊接学术年会

作者： P．Le masson E.Artioukhine T．Loulou P．Rogeon m．Carin m．Dumons J．Costa LET2E/ETm:Laboratoire d’Etudes Thermique Energétique et Environnement／Equipe Thermophysique et matériaux.Université de Bretagne sud Institut FEmTO-ST Centre Energétique Environnement．Ecole des mines d’Albi

In the previous work [1], we have analyzed the feasibility of the estimation for a source term S(x, z,t) in a transversal section. The present study is concerned with a two-dimensional inverse phase change problem. The goal is the estimation of the dissipated heat flux in the liquid zone (reconstruction of a source term in the energy equation) from experimentally measured temperatures in the solid zone. This work has an application in the electron beam welding of steels of thickness about 8 cm. The direct thermo-metallurgical problem is treated in a quasi steady two-dimensional longitudinal section (x,y). The beam displacement is normally in the y direction. But in the quasi steady simulation, the beam is steady in the study section. The sample is divided in the axial direction Z in few sections. At each section, a source term is defined with a part of the beam and creates a vaporized zone and a fused zone. The goal of this work is the rebuilding of the complete source term with the estimations at each section. In this paper we analyze the feasibility of the estimation. For this work, we use only the simulated measurements without noise.

Evolutionary diversity can be driven by the interaction of plants with different environments. molecular bases involved in ecological adaptations to abiotic constraints can be explored using genomic tools. Legumes are major crops worldwide and soil salinity is a main stress affecting yield in these plants. We analyzed in the medicago truncatula legume the root transcriptome of two genotypes having contrasting responses to salt stress： TN1.11, sampled in a salty Tunisian soil, and the reference Jemalong A17 genotype. TN1.11 plants show increased root growth under salt stress as well as a differential accumulation of sodium ions when compared to A17. Transcriptomic analysis revealed specific gene clusters preferentially regulated by salt in root apices of TN1.11, notably those related to the auxin pathway and to changes in histone variant isoforms. many genes encoding transcription factors （TFs） were also differentially regulated between the two genotypes in response to salt. Among those selected for functional studies, overexpression in roots of the A17 ge- notype of the bHLH-type TF most differentially regulated between genotypes improved significantly root growth under salt stress. Despite the global complexity of the differential transcriptional responses, we propose that an increase in this bHLH TF expression may be linked to the adaptation of m. truncatula to saline soil environments.

It is demonstrated that the form birefringence related to the so-called nanogratings is quantitatively correlated to the porosity-filling factor of these nanostructures. We reveal that matters surrounding the nanopores exhibit significant refractive index decrease which is likely due to the fictive temperature increase and/or the presence of a significant amount of interstitial O2. The control of the porosity was achieved by adjusting the laser pulse energy and the number of pulses/micron i.e. the overlapping rate. Applications can be numerous in fast material processing by the production of nanoporous matter, and photonics by changing the optical properties.

The paper includes discussions on the important role of neutron and alpha configurations in proton-rich nuclei in nuclear astrophysics in terms of nucleosynthesis under extremely high-temperature hydrogenburning conditions. The νp-process, which is supposed to take place at the very early epoch of type II supernovae, has considerable neutrons and alphas together with protons. The alpha-induced reactions on proton-rich unstable nuclei in the light mass regions is expected to play a crucial role, but very few of them were investigated well yet because of the experimental difficulties. Specifically, I report our recent experimental effort for the breakout process from the pp-chain region,~7Be(α, γ)^(11)C(α,p)^(14)N under the νp-process. The neutron-induced reactions on proton-rich nuclei, which is even more a challenging subject, were investigated previously for very few nuclei. One possible experimental method is the Trojan Horse method(THm). We successfully have applied THm to the ^(18)F(n,α)^(14)N reaction study with an unstable beam of ^(18)F.
