There are many theories that explain diffraction phenomena, but the simplest one is the Huygens-Fresnel theory, which is surprisingly accurate in most cases. This theory is sufficient to explain all diffraction effects appearing in optical systems, with the exception of the value of the resulting phase. If any of the…

Several important relations in thick optical systems may be found with only the definitions of effective focal length and Lagrange’s theorem. This chapter considers the simplest case of a system of two thin lenses separated by a finite distance. The Lagrange invariant in a system of thin lenses may adopt another form…
FIBO 2013 – Erstmals mit physiotag Vom 11. bis 14. April 2013 findet die FIBO, die weltweit führende Messe für Fitness, Wellness und Gesundheit, in der koelnmesse in Köln statt. In diesem Jahr gibt es zum ersten Mal einen Programmpunkt, der sich speziell an Physiotherapeuten richtet: den physiotag am 13. April, den de…
Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.
No presente trabalho, buscou-se avaliar as mudanas promovidas pela substituio parcial e total de TiO 2 por GeO 2 em vidros niobofosfato co-dopados com Er 3+ /Yb 3+ previamente estudados
Rapid growth in production of automobiles has increased emissions. Automotive control engineers use innovative control techniques to meet the upcoming emission standards. This paper proposes a novel method of employing artificial neural network (ANN) based predictive controller design. The controller predicts the inje…
Capillary pressure exists whenever reservoir rock pores, which are of capillary sizes, are saturated with two or more immiscible fluid phases.1 In 1941, Leverett2 first stated that the interfacial boundary between two immiscible fluid phases present in a porous medium is curved due to IFT between the fluids. He ascrib…

A comunidade fitoplanctônica pode ser regulada pelos controles bottom-up (nutrientes) e top-down (predadores). A disponibilidade de nutrientes vem sendo considerada como o fator mais expressivo nesta regulação, entretanto, estudos mostram que o fitoplâncton também pode ser fortemente regulado pelo zooplâncton. Experim…
A travers cette etude, nous voulons mettre en evidence l'impact du rajout d'un composite a base de fibres de carbone et de resine epoxy sur le renforcement des poutres en bois. Nous avons etudie plusieurs essences utilisees en construction (Epicea, Pin sylvestre et Douglas) et avons teste ce renforcement grâce a la fl…
Swadeshmukul Santra of the University of Central Florida described (Tetrahedron Lett. 2009, 50, 124) a simple preparation of silica nanoparticles that efficiently catalyzed the anti-Markovnikov addition of thiophenol to alkenes (illustrated) and also to alkynes. Akiya Ogawa of Osaka Prefecture University devised (Tetr…
Amos B. Smith III of the University of Pennsylvania found (Synlett 2009, 3131) that the advanced SAMP intermediate 1 could be deprotected to 2 without racemization under mild oxidative conditions. Akihiko Ouchi of the National Institute of Advanced Industrial Science and Technology, Tsukuba, showed (Organic Lett. 2009…
Chapter 4 covered the absolute permeability of the reservoir rock, which by definition signifies that the rock pore space is fully saturated by a single-phase fluid. However, petroleum reservoirs are seldom such simple single-phase fluid systems, that is, the pore space is typically distributed between either two (gas…
Foram sintetizadas, por polimerizacao interfacial, microcapsulas de poliuretano contendo diisocianato em seu interior. As microcapsulas foram preparadas variando-se a velocidade de agitacao (1500, 1000 e 700rpm) e o tipo de isocianato utilizado (4,4-difenilmetano diisocianato (MDI) ou isoforona diisocianato (IPDI)).Fo…
Durante a producao de bobinas de aco em uma laminacao a quente o controle da temperatura de bobinamento do material e de suma importância para o processo. A sua variacao pode causar mudancas de propriedades mecânicas e micro-estruturas dos materiais, gerando materiais com nao conformidades, o que pode gerar perdas. Es…
We used X-ray/neutron diffraction to determine the low temperature (LT) structure of IrTe2. A structural modulation was observed with a wavevector of k =(1/5, 0, 1/5) below Ts?285 K, accompanied by a structural transition from a trigonal to a triclinic lattice. We also performed the first principles calculations for h…
Materials is instituting an annual award to recognize the outstanding papers in the area of materials science and engineering published in Materials. We are pleased to announce the first “Materials Best Paper Award” for 2013. Nominations were selected by the Section Editor-in-Chiefs and Editorial Board members of Mate…
