Electrochemical phase formation (ECPF): Nucleation growth vis-a-vis adsorption models

The nucleataon growth model of electrochemical phase formation is analysed for the hnear potential sweep input Apart from deducing diagnostic criteria and method~ of estimating model parameters, the predictions of the nucleation growth model are compared and contrasted with those of a sample adsorption model A dastlnCtlOn is made possible between adsorption and phase transition, which seems useful for understanding the nature of ECPF phenomena, especially underpotentlal deposition (UPD).

Potential of VIS-NIR Spectroscopy to predict perceived ‘muddy’ taint in australian farmed barramundi

Sensory analysis of food involves the measurement, interpretation and understanding of human responses to the properties of food perceived by the senses such as sight, smell, and taste (Cozzolino et al. 2005). It is important to have a quantitative means for assessing sensory properties in a reasonable way, to enable the food industry to rapidly respond to the changing demands of both consumers and the market. Aroma and flavour are among the most important properties for the consumer, and numerous studies have been performed in attempts to find correlations between sensory qualities and objective instrumental measurements. Rapid instrumental methods such as near infrared spectroscopy (NIR) might be advantageous to predict quality of different foods and agricultural products due to the speed of analysis, minimum sample preparation and low cost. The advantages of such technologies is not only to assess chemical structures but also to build an spectrum, characteristic of the sample, which behaves as a “finger print” of the sample.

Exploring the potential of VIS-NIR spectroscopy to predict sensory properties of foods

Recognition and enforcement in cross-border insolvency law: A proposal for judicial gap-filling

This Article analyzes the recognition and enforcement of cross-border insolvency judgments from the United States, United Kingdom, and Australia to determine whether the UNCITRAL Model Law’s goal of modified universalism is currently being practiced, and subjects the Model Law to analysis through the lens of international relations theories to elaborate a way forward. We posit that courts could use the express language of the Model Law text to confer recognition and enforcement of foreign insolvency judgments. The adoption of our proposal will reduce costs, maximize recovery for creditors, and ensure predictability for all parties.

New Governance and the EU Courts : The Experimentalist Architecture of Judicial Decision-Making

The dissertation examines the role of the EU courts in new governance. New governance has raised unprecedented interest in the EU in recent years. This is manifested in a plethora of instruments and actors at various levels that challenge more traditional forms of command-and-control regulation. New governance and political experimentation more generally is thought to sap the ability of the EU judiciary to monitor and review these experiments. The exclusion of the courts is then seen to add to the legitimacy problem of new governance. The starting point of this dissertation is the observation that the marginalised role of the courts is based on theoretical and empirical assumptions which invite scrutiny. The theoretical framework of the dissertation is deliberative democracy and democratic experimentalism. The analysis of deliberative democracy is sustained by an attempt to apply theoretical concepts to three distinctive examples of governance in the EU. These are the EU Sustainable Development Strategy, the European Chemicals Agency, and the Common Implementation Strategy for the Water Framework Directive. The case studies show numerous disincentives and barriers to judicial review. Among these are questions of the role of courts in shaping governance frameworks, the reviewability of science-based measures, the standing of individuals before the courts, and the justiciability of soft law. The dissertation analyses the conditions of judicial review in each governance environment and proposes improvements. From a more theoretical standpoint it could be said that each case study presents a governance regime which builds on legislation that lays out major (guide)lines but leaves details to be filled out at a later stage. Specification of detailed standards takes place through collaborative networks comprising members from national administrations, NGOs, and the Commission. Viewed this way, deliberative problem-solving is needed to bring people together to clarify, elaborate, and revise largely abstract and general norms in order to resolve concrete and specific problems and to make law applicable and enforceable. The dissertation draws attention to the potential of peer review included there and its profound consequences for judicial accountability structures. It is argued that without this kind of ongoing and dynamic peer review of accountability in governance frameworks, judicial review of new governance is difficult and in some cases impossible. This claim has implications for how we understand the concept of soft law, the role of the courts, participation rights, and the legitimacy of governance measures more generally. The experimentalist architecture of judicial decision-making relies upon a wide variety of actors to provide conditions for legitimate and efficient review.

Microwave assisted synthesis and UV-Vis spectroscopic studies of silver nanoparticles synthesized using vanillin as a reducing agent

The present investigation explores the adaptability of a microwave assisted route to obtain silver nanoparticles by the reduction of AgNO3 with vanillin, an environmentally benign material. Anionic surfactants such as AOT and SDS were used separately for encapsulating AgNPs and their role was compared. The UV-Visible absorption spectra present a broad SPR band consisting of two peaks suggesting the formation of silver nanoparticle with bimodal size distribution. The TEM image shows particles with spherical and hexagonal morphologies which confirms the results of UV-Vis studies. The anisotropy in the particle morphology can be attributed to the surface oxidation which in turn produces Ag@Ag2O core-shell nanostructures. Thus an intriguing feature of this system is that the obtained colloid is a mixture of AgNPs with and without Ag2O layers. Studies on the influence of pH on the stability of the synthesized nanoparticles revealed that the presence of excess Ag2O layers has a profound influence on it. Ag2O layers can be removed from AgNPs' surface by changing the solution pH to the acidic regime. The present study attests the enhanced ability of AOT in stabilizing the AgNPs in aqueous media.

Nonlinear Optical Properties and Temperature-Dependent UV-Vis Absorption and Photoluminescence Emission in 2D Hexagonal Boron Nitride Nanosheets

Recently, a lot of interest has been centred on the optical properties of hexagonal boron nitride (h-BN), which has a similar lattice structure to graphene. Interestingly, h-BN has a wide bandgap and is biocompatible, so it has potential applications in multiphoton bioimaging, if it can exhibit large nonlinear optical (NLO) properties. However, extensive investigation into the NLO properties of h-BN have not been done so far. Here, NLO properties of 2D h-BN nanosheets (BNNS) are reported for the first time, using 1064-nm NIR laser radiation with a pulse duration of 10 ns using the Z-scan technique. The reverse saturable absorption occurs in aqueous colloidal solutions of BNNS with a very large two-photon absorption cross section (sigma(2PA)) of approximate to 57 x 10(-46) cm(4) s(-1) photon(-1). Also, by using UV-Vis absorption spectroscopy, the temperature coefficient of the bandgap (dE(g)/dT) of BNNS is determined to be 5.9 meV K-1. Further defect-induced photoluminescence emission in the UV region is obtained in the 283-303 K temperature range, under excitations of different wavelengths. The present report of large sigma(2PA) combined with stability and biocompatibility could open up new possibilities for the application of BNNS as a potential optical material for multiphoton bioimaging and advanced photonic devices.

El poder judicial en la organización constitucional

Resumen: La potestad judicial en el principio del constitucionalismo moderno aparece diseñada de modo impreciso y sin función clara. Ella adquiere entidad en el derecho norteamericano cuando la propia jurisprudencia diseña el control de constitucionalidad. Este es resistido por el derecho continental europeo, aunque finalmente aceptado, con otras modalidades, luego de la Segunda Guerra Mundial. Con el tiempo ese poder excede el mero control de las leyes, para transformarse a través de sus sentencias en órgano que compite en la creación del derecho con los poderes políticos encargados de la función de gobierno. El autor considera que esa función basada en principios de normas internacionales de discutible vigencia y sin el freno de la consideración, por el nominalismo que la anima, de la existencia de un orden objetivo termina originando un poder incontrolable con riesgo de destrucción social.

El objeto formal de la vis cogitativa en Santo Tomás de Aquino

Resumen: De acuerdo a la mente de Santo Tomás de Aquino, la potencia de conocimiento sensible que se denomina «cogitativa » es susceptible de una doble consideración. Por un lado, es la estimativa animal y, como tal, aprehende su mismo objeto formal quod, esto es, las intenciones de beneficio o perjuicio a nivel sensible. Pero a causa de su particular modo de operar, esas intenciones no son conocidas por ella solamente en orden a la conservación del individuo humano o de la especie a la que él pertenece. El reconocimiento de una doble dimensión de la cogitativa está en Santo Tomás justificado por la particular relación que existe entre ella y la razón universal. Por un lado, la cogitativa no es una facultad distinta de la estimativa natural. Por esto, ella aprehende las intenciones necesarias para la perfección de la vida sensitiva humana. Por otro lado, la razón ejerce sobre la cogitativa un influjo particular que la hace operar a su modo, esto es, de manera discursiva. Este carácter móvil en la aprehensión de la cogitativa permite la conformación de una experiencia a nivel sensible, en virtud de la cual su objeto formal se ve ampliado. Esto resulta aún más razonable si se tiene en cuenta que el conocimiento sensorial del hombre prepara el intelectual. De esta manera, la cogitativa no aprehende simplemente al individuo como beneficioso o perjudicial para la subsistencia del cognoscente, sino como sujeto de una cierta naturaleza.

Comentario de un caso judicial inédito : diócesis, parroquia, municipio y la observancia del Derecho Canónico

Resumen: Se analiza un caso judicial inédito que involucra a una diócesis, a una parroquia, a un personal municipal y a un municipio de la provincia de Buenos Aires. Un agente municipal es adscripto provisoriamente, por decreto del señor intendente, para desempeñarse en una Cáritas diocesana, y luego este agente pasa a desempeñarse en una Cáritas parroquial de una parroquia perteneciente a esa diócesis, todo lo cual es comunicado y aceptado por el municipio, que es su empleador. Luego de desempeñarse un tiempo en esa Cáritas parroquial, el personal municipal primero intima y después inicia un juicio por despido contra la diócesis alegando una relación laboral no registrada con ésta. El caso lleva a plantear la aplicación del derecho canónico para su resolución. Se explica que la diócesis y las parroquias poseen personería jurídica propia, y que la acción judicial contra la diócesis es improcedente. Se expone en detalle el planteamiento realizado en el juicio por el agente municipal y por la diócesis.
