Waveguiding properties of a photonic crystal fiber with a solid core surrounded by four large air holes
2009
The polarization-dependent guiding properties of a hexagonal-lattice photonic crystal fiber with a solid-core surrounded by four large air holes are investigated. The appearance of a polarization dependent cutoff frequency, together with several parameters as the birefringence, the modal effective area, the group velocity dispersion and the polarization dependent loss are analyzed. A collection of fibers with different structural parameters were fabricated and characterized. An effective anti-guide structure from at least 450 nm to 1750 nm, a polarizing fiber with a polarization dependent loss of 16 dB/m at 1550 nm, and an endlessly singlemode polarization-maintaining fiber with group biref…
apuesta por un reconocimiento constitucional amplio del derecho al trabajo y a la seguridad social en Ecuador
2021
espanolLa integracion del derecho al trabajo en el constitucionalismo social de posguerra se caracterizo, entre otras cuestiones, por la incorporacion de la division del trabajo, diferenciando entre aquel remunerado, integrado en las normas constitucionales y sobre el que se asento en gran medida el reconocimiento de un amplio conjunto de derechos sociales; y el no remunerado, ausente del reconocimiento constitucional y normativo y condenado a la invisibilizacion y a ser acumulado sobre el anterior. Esta diferenciacion se fundamento, evidentemente, en la division sexual del trabajo integrada en la conjuncion del patriarcado con el sistema capitalista y recogida en las normas del constitucio…
Optical gain, spontaneous and stimulated emission of surface plasmon polaritons in confined plasmonic waveguide
2010
International audience; We develop a theoretical model to compute the local density of states in a confined plasmonic waveguide. Based on this model, we derive a simple formula with a clear physical interpretation for the lifetime modification of emitters embedded in the waveguide. The gain distribution within the active medium is then computed following the formalism developed in a recent work [Phys. Rev. B 78, 161401 (2008)], by taking rigorously into account the pump irradiance and emitters lifetime modifications in the system. We finally apply this formalism to describe gain–assisted propagation in a dielectric–loaded surface plasmon polariton waveguide.
A Paradigm Interpreting the City and the Analytic Network Process for the Management of Urban Transformations
2018
When urban and environmental transformations occur in areas where the equilibrium between nature and culture is complex and fragile, public ad-ministrations could decide to induce private investments using several tools, such as financial contributions to those projects of refurbishment that better re-spect the purpose of improving the environmental quality and of preserving the local architecture. Multicriteria models may support public decision process re-garding this issue, but it is essential to adopt a scientific paradigm that provides a major theoretical reference. This study proposes the development of a net-work model based on the scientific paradigm by Rizzo and the Analytic Net-wo…

Moraalisten ja esteettisten arvostelmien suhde taiteessa : katsaus kohtuullisiin teorioihin
2015
Tämä tutkielma käsittelee moraalisten ja esteettisten arvostelmien suhdetta taiteessa keskittyen kolmeen kohtuulliseksi teoriaksi katsottuun näkemykseen: Noël Carrollin kohtuulliseen moralismiin, Berys Gautin etikismiin sekä Andersonin ja Deanin kohtuulliseen autonomismiin. Tarkoitukseni on selvittää, millä tavalla kukin näistä teoreetikoista näkee taiteen moraalin ja estetiikan suhteen. Tutkimuskysymyksessäni haluan ottaa selvää, onko taiteessa sekä moraalisia että esteettisiä arvostelmia ja vaikuttavatko nämä toisiinsa. Ennen siirtymistä varsinaisiin kohtuullisiin teorioihin pohjustan aihetta selvittämällä, kuinka taiteen moraaliin ja estetiikkaan on suhtauduttu historian kuluessa ja mite…

Production and detection of atomic hexadecapole at Earth's magnetic field
2007
Anisotropy of atomic states is characterized by population differences and coherences between Zeeman sublevels. It can be efficiently created and probed via resonant interactions with light, the technique which is at the heart of modern atomic clocks and magnetometers. Recently, nonlinear magneto-optical techniques have been developed for selective production and detection of higher polarization moments, hexadecapole and hexacontatetrapole, in the ground states of the alkali atoms. Extension of these techniques into the range of geomagnetic fields is important for practical applications. This is because hexadecapole polarization corresponding to the $\Delta M=4$ Zeeman coherence, with maxim…
Antioxidant Activity of Sicilian Pistachio (Pistacia veraL. Var. Bronte) Nut Extract and Its Bioactive Components
2007
Pistacia vera L. is the only species of Pistacia genus producing edible nuts. This paper investigates the antioxidant potential of a Sicilian variety of pistachio nut by chemical as well as biological assays and measured antioxidant vitamins and a number of antioxidant polyphenols in either the hydrophilic and/or the lipophilic nut extract. In accordance with the majority of foods, the total antioxidant activity, measured as a TAA test, was much higher (50-fold) in the hydrophilic than in the lipophilic extract. Substantial amounts of total phenols were measured. The hydrophilic extract inhibited dose-dependently both the metal-dependent and -independent lipid oxidation of bovine liver micr…
Džo Rogana pieredze: veidojot vīrišķību vai viela pārdomām
2021
Savā bakalaura disertācijā ‘Džo Rogana pieredze: Veidojot Vīrišķību vai Viela Pārdomām’ es koncentrējos uz jauniem, pieaugušiem, latviešu vīriešiem un viņu pārdomām par Džo Rogana raidieraksti, un par vīrišķības atspoguļojuma aktualitāti sociālajos medijos. Tēzes mērķis ir saprast, kāpēc cilvēki skatās un klausās Džo Rogana raidierakstu, vai par dzimumu bieži tiek runāts, kā Rogans runā par vīrišķību un tās nozīmi mūsdienu laikā, un vai dalībnieki pievērš tam uzmanību, klausoties raidierkastu. Šajā pētījumā aplūkota labi pazīstama riadieraksta un raidierakstītāja iekšējā pasaule no klausītāja viedokļa, kas saņēmusi negatīvu atgriezenisko saiti dzimumu normu ziņā.
