Diversificación vitivinícola en el marco de Jerez: vinos de vendimia tardía
En este trabajo se presentaron los resultados obtenidos al elaborar Vinos Dulces Naturales, procedentes de vendimia tardía, en la cosecha de 2005, con las variedades Moscatel de Alejandría, Palomino fino y Palomino de Jerez, cultivadas en una parcela ubicada en el CIFA Rancho de la Merced, en el pago Macharnudo de Jerez de la Frontera y proceden de selección clonal.
Los vinos se analizaron y cataron destacando el de Moscatel por sus aromas característicos, intensos y delicados. Los vinos de las tres variedades siendo dulces no fueron empalagosos, presentando un final de boca persistente y muy agradable.</p
Jupiter as an exoplanet: UV to NIR transmission spectrum reveals hazes, a Na layer and possibly stratospheric H2O-ice clouds
Currently, the analysis of transmission spectra is the most successful
technique to probe the chemical composition of exoplanet atmospheres. But the
accuracy of these measurements is constrained by observational limitations and
the diversity of possible atmospheric compositions. Here we show the UV-VIS-IR
transmission spectrum of Jupiter, as if it were a transiting exoplanet,
obtained by observing one of its satellites, Ganymede, while passing through
Jupiter's shadow i.e., during a solar eclipse from Ganymede. The spectrum shows
strong extinction due to the presence of clouds (aerosols) and haze in the
atmosphere, and strong absorption features from CH4. More interestingly, the
comparison with radiative transfer models reveals a spectral signature, which
we attribute here to a Jupiter stratospheric layer of crystalline H2O ice. The
atomic transitions of Na are also present. These results are relevant for the
modeling and interpretation of giant transiting exoplanets. They also open a
new technique to explore the atmospheric composition of the upper layers of
Jupiter's atmosphere.Comment: Accepted for publication in ApJ Letter
Factores jurídicos para considerar la imprescriptibilidad de la responsabilidad civil extracontractual derivado del daño ambiental, en el ordenamiento jurídico peruano
La Tesis que hemos denominado “Factores jurídicos para considerar la
imprescriptibilidad de la Responsabilidad Civil Extracontractual derivado
del daño ambiental, en el ordenamiento jurídico peruano”, se orienta a
determinar las consideraciones jurídicas que hacen conveniente la aplicación
de la figura de la imprescriptibilidad de la Responsabilidad Civil
Extracontractual en cuestiones ambientales en nuestra normatividad nacional.
Cuando hablamos de daño ambiental nos estamos refiriendo a todo
menoscabo material que sufre el ambiente o algunos de sus componentes, que
puede ser causado contraviniendo disposición jurídica y que genera efectos
negativos actuales y potenciales. En muchas ocasiones son las actividades
económicas en su mayoría las que dañan el medio ambiente surgiendo el
instituto de la responsabilidad civil como una herramienta para reparar el daño
causado; siendo su principal objetivo el de responsabilizar al contaminador, y
en consecuencia solo si éste se ve obligado a sufragar los costos relacionados
con el daño ambiental reducirá los niveles de contaminación; cumpliendo de
esta manera una doble función, por un lado de reparar y por otro la de prevenir
daños ambientales.
En este sentido, la formulación de nuestro Problema fue el siguiente: ¿CUÁLES
SON LOS FUNDAMENTOS JURÍDICOS QUE SUSTENTAN LA APLICACIÓN
DE LA IMPRESCRIPTIBILIDAD DE LA RESPONSABILIDAD CIVIL
EXTRACONTRACTUAL DERIVADO DEL DAÑO AMBIENTAL, EN EL
ORDENAMIENTO JURÍDICO PERUANO?, frente a lo cual nos planteamos los
siguientes objetivos principales: Determinar las consideraciones jurídicas que

Responsabilidad Civil e identificar los factores de atribución que acoge la
normatividad peruana y la doctrina más calificada.The thesis we have called ""Legal Factors to consider the applicability of the

Structure and dynamics of colloidal depletion gels: coincidence of transitions and heterogeneity
Transitions in structural heterogeneity of colloidal depletion gels formed
through short-range attractive interactions are correlated with their dynamical
arrest. The system is a density and refractive index matched suspension of 0.20
volume fraction poly(methyl methacyrlate) colloids with the non-adsorbing
depletant polystyrene added at a size ratio of depletant to colloid of 0.043.
As the strength of the short-range attractive interaction is increased,
clusters become increasingly structurally heterogeneous, as characterized by
number-density fluctuations, and dynamically immobilized, as characterized by
the single-particle mean-squared displacement. The number of free colloids in
the suspension also progressively declines. As an immobile cluster to gel
transition is traversed, structural heterogeneity abruptly decreases.
Simultaneously, the mean single-particle dynamics saturates at a localization
length on the order of the short-range attractive potential range. Both
immobile cluster and gel regimes show dynamical heterogeneity. Non-Gaussian
distributions of single particle displacements reveal enhanced populations of
dynamical trajectories localized on two different length scales. Similar
dependencies of number density fluctuations, free particle number and dynamical
length scales on the order of the range of short-range attraction suggests a
collective structural origin of dynamic heterogeneity in colloidal gels.Comment: 14 pages, 10 figure
Queremismo: um movimento político-popular e as suas conseqüências para a esquerda nacionalista brasileira
Movimento político-popular o Queremismo teve relações genéticas com a criação do PTB. As lutas pela participação direta e decisiva dos trabalhadores e demais camadas populares em defesa de suas conquistas e para a realização de suas aspirações e por uma Assembléia Nacional Constituinte que consolidasse em seu texto final as conquistas trabalhistas e sociais até então obtidas, lhes garantindo a representação e a participação política, foram geradas na dinâmica do movimento. Isso foi condicionante do caráter e do papel futuro do PTB, tornando-o muito mais que um partido que foi obra de Getúlio e da estrutura institucional do Estado Novo. O movimento queremista foi, ainda, o último momento, antes dos anos 1950, em que os principais agentes políticos do campo nacionalista de esquerda interagem por objetivos políticos táticos e estratégicos comuns
Comparison of structure and transport properties of concentrated hard and soft sphere fluids
Using Newtonian and Brownian dynamics simulations, the structural and
transport properties of hard and soft spheres have been studied. The soft
spheres were modeled using inverse power potentials (, with
the potential softness). Although the pressure, diffusion coefficient and
viscosity depend at constant density on the particle softness up to extremely
high values of , we show that scaling the density with the freezing point
for every system effectively collapses these parameters for
(including hard spheres), for large densities. At the freezing points, the long
range structure of all systems is identical, when the distance is measured in
units of the interparticle distance, but differences appear at short distances
(due to the different shape of the interaction potential). This translates into
differences at short times in the velocity and stress autocorrelation
functions, although they concur to give the same value of the corresponding
transport coefficient (for the same density to freezing ratio); the microscopic
dynamics also affects the short time behaviour of the correlation functions and
absolute values of the transport coefficients, but the same scaling with the
freezing density works for Newtonian or Brownian dynamics. For hard spheres,
the short time behaviour of the stress autocorrelation function has been
studied in detail, confirming quantitatively the theoretical forms derived for
it.Comment: 8 pages, 10 figure
Retrieval of nitric oxide in the mesosphere and lower thermosphere from SCIAMACHY limb spectra
We use the ultra-violet (UV) spectra in the range 230–300 nm from the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) to retrieve the nitric oxide (NO) number densities from atmospheric emissions in the gamma-bands in the mesosphere and lower thermosphere. Using 3-D ray tracing, a 2-D retrieval grid, and regularisation with respect to altitude and latitude, we retrieve a whole semi-orbit simultaneously for the altitude range from 60 to 160 km. We present details of the retrieval algorithm, first results, and initial comparisons to data from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS). Our results agree on average well with MIPAS data and are in line with previously published measurements from other instruments. For the time of available measurements in 2008–2011, we achieve a vertical resolution of 5–10 km in the altitude range 70–140 km and a horizontal resolution of about 9° from 60° S–60° N. With this we have independent measurements of the NO densities in the mesosphere and lower thermosphere with approximately global coverage. This data can be further used to validate climate models or as input for them
