Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Available in PDF, EPUB and Kindle. Book excerpt: What do we know of masculinities in non-patriarchal societies? Indigenous peoples of the Americas and beyond come from traditions of gender equity, complementarity, and the sacred feminine, concepts that were unimaginable and shocking to Euro-western peoples at contact. "Indigenous Men and Masculinities", edited by Kim Anderson and Robert Alexander Innes, brings together prominent thinkers to explore the meaning of masculinities and being a man within such traditions, further examining the colonial disruption and imposition of patriarchy on Indigenous men. Building on Indigenous knowledge systems, Indigenous feminism, and queer theory, the sixteen essays by scholars and activists from Canada, the U.S., and New Zealand open pathways for the nascent field of Indigenous masculinities. The authors explore subjects of representation through art and literature, as well as Indigenous masculinities in sport, prisons, and gangs. "Indigenous Men and Masculinities" highlights voices of Indigenous male writers, traditional knowledge keepers, ex-gang members, war veterans, fathers, youth, two-spirited people, and Indigenous men working to end violence against women. It offers a refreshing vision toward equitable societies that celebrate healthy and diverse masculinities.

Book excerpt: CETTE ETUDE A ETE REALISEE EN BRETAGNE, DANS UNE REGION D'AGRICULTURE INTENSIVE, DANS UNE ZONE HUMIDE, A L'INTERFACE D'UN VERSANT INTENSEMENT CULTIVE ET D'UN COURS D'EAU. LE SUIVI SIMULTANE DE LA DYNAMIQUE DU FE(II), DU CARBONE ORGANIQUE DISSOUS, DES NITRATES, ET DES MICROPOLLUANTS METALLIQUES CU ET ZN PERMET DE METTRE EN EVIDENCE : LE BRUIT DE FOND GEOCHIMIQUE, L'IMPACT DES EPANDAGES, LA DYNAMIQUE SAISONNIERE DU SOL EN FONCTION DES CONDITIONS DE SATURATION ET D'OXYDATION, PARTICULIEREMENT SUIVANT QUE LE MILIEU EST EN CONDITIONS AEROBIES OU ANAEROBIES. DES PROTOCOLES ONT ETE DEVELOPPEES AFIN DE PRESERVER AU MAXIMUM LES CARACTERISTIQUES DE LA SOLUTION DU SOL. IL EXISTE UNE DYNAMIQUE TEMPORELLE CONSTITUEE DE PLUSIEURS CYCLES DE REDUCTION/REOXYDATION : SATURATION EN EAU N'EST PAS SYNONYME DE MILIEU REDUCTEUR. LA REALISATION DE CONDITIONS REDUCTRICES DEPEND DE LA RECHARGE EN OXYGENE DISSOUS PAR LES PLUIES. ON N'OBSERVE PAS D'EFFET LIMITANT DE LA TEMPERATURE SUR LA REDUCTION DU MILIEU. LES EPANDAGES APPORTENT DU CARBONE ORGANIQUE SOLUBLE DE TOUS POIDS MOLECULAIRES ET DES METAUX CU, ZN. UN PROCESSUS DE CHROMATOGRAPHIE SEPARE LE LONG DU VERSANT LES DIFFERENTS COMPOSES. EN CONDITIONS ANAEROBIES, LA MICROFLORE RESTE ACTIVE ET SEMBLE MEME STIMULEE PAR L'APPORT DE MATIERE ORGANIQUE FACILEMENT BIODEGRADABLE DU LISIER. LA DENITRIFICATION S'OBSERVE LORSQUE LA ZONE HUMIDE PASSE POUR LA PREMIERE FOIS EN CONDITIONS ANOXIQUES A LA FIN DE LA PERIODE SECHE. MAIS LORS DES CYCLES D'OXYDATION/REDUCTION ULTERIEURS, ON OBSERVE LA COEXISTENCE DE FE(II) ET DE NITRATES EN SOLUTION. LE FE(II) EST ALORS CONTROLE PAR L'EQUILIBRE AVEC UN HYDROXYDE MIXTE DE FE(II) ET DE FE(III), SITUE PLUS HAUT DANS L'ECHELLE DE REDUCTION QUE LE COUPLE NITRATE/NITRITE. IL PEUT DONC EXISTER UN FACTEUR D'ORDRE BIOGEOCHIMIQUE LIMITANT LA DENITRIFICATION. LE CUIVRE ET LE ZINC SONT MOBILISES DANS LE PAYSAGE LORS DE LA REDUCTION DES OXYDES DE FER ET PEUVENT MIGRER VERS LE RESEAU HYDROGRAPHIQUE.

Download or read book Colloïdes et compositions élémentaires des solutions de sols written by Mathieu Pédrot and published by . This book was released on 2009 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ubiquitous, dynamic, as well as characterized by important surface complexation ability, colloids are meant to play a key role in trace element sequestration in both waters and soils. This study was aimed on improving the understanding of the role played by colloids in trace element carriage in focusing on: (i) the study of the impact exerted by physico-chemical parameters on the colloidal and elemental composition of the dissolved phase circulating within wetlands, (ii) the colloid genesis ways and their respective role as carriers and vectors of trace elements in waters and soils. The different performed experiments put forward a colloidal control for a lot of trace elements occurring in the soil solution. Sorne of these latter are strongly complexed by the colloidal pool such as (Al, Cr, U, Mo, Pb, Ti, Th, Fe, and REE), while others are more little complexed (Cu, Cd, Co, and Ni), and a last part which remains unreactive regards to colloids (Li, B, K, Na, Rb, Si, Mg, Sr, Ca, Mn, Ba and V). pH appears to be one major control parameter on the elemental composition of the soil solution, with any pH increase or decrease putting strong impact on the soil solution colloidal and elemental compositions. Furthermore, pH does largely play on the humic substance conformation, which are the main active organic molecules involved in the trace element sequestration within nature, impacting thus their own mobility and that of associated trace elements as weIl. This study also evidences the occurrence of supramolecular associations of small organic molecules within humic substances, as well as the presence of Fe-nanoparticles intimately bound to organic matter. These latter can sequestrate specific elements su ch as Pb or Ti. This study allowed also to evaluate the impact of the humic substances on both the Fe oxidation-hydrolysis rate and the size of the precipitated oxyhydroxides. Humic substances slow down and decrease the Fe oxidation-hydrolysis reactions and impact directly the Fe oxide size. Iron is therefore, either as ionic state complexed with humic substances, or as nanopartic1es inc1uded within an organic matrix. The bioavailability of these Fe-nanopartic1es to be used as electron acceptor by Schewanella putrefaciens bacteria during bio-reduction was then tested compared to that of crystallyzed iron in inorganic medium. Mixed Fe-humic substance colloids showed a more important bioavailablity than did inorganic crystallyzed Fe. This latter result evidences that in wetlands, mixed Fe-organic matter colloids represent a major Fe stock, which is regularly requested by microfauna, since much more available than can be that of the geochemical bedrock/soil.

Download or read book Contamination des sols written by Anne Tremel-Schaub and published by L'Editeur : EDP Sciences. This book was released on 2005 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Un des aspects de la sécurité alimentaire est le contrôle des teneurs en éléments-traces des aliments d'origine végétale (pour l'homme et le bétail). Pour assurer de ce point de vue la qualité des denrées, il est nécessaire de connaître les facteurs régissant le transfert des éléments traces du sol vers l'organe récolté de la plante, puis ceux qui ont une incidence sur la teneur finale de l'aliment et donc sur l'exposition des consommateurs aux éléments-traces. L'objectif principal de cet ouvrage est de faire l'état de l'art sur le transfert de douze éléments-traces (As, Cd, Co, Cr, Cu, Hg, Mo, Ni, Pb, Se, TI, Zn) des sols vers les plantes à vocation alimentaire et d'aborder rapidement l'aspect alimentation d'origine végétale et l'exposition des consommateurs français aux éléments-traces issus des aliments d'origine végétale. L'intérêt de ce livre est également de servir de manuel de référence pratique dans les domaines suivants : teneurs courantes en éléments-traces dans les organes consommés des végétaux, seuils réglementaires ou recommandés en éléments-traces dans les aliments d'origine végétale, expérimentations de plein champ ayant pour but d'étudier le transfert sol-plante des éléments-traces.
