Influence of Fining and Tartaric Stabilisation Procedures on White Wine Mannoprotein Content
Limpidity is a major quality attribute in white wine appreciation. After alcoholic fermentation and ageing,white wines are normally subjected to protein and tartaric stabilisation, followed by filtration. The impactof bentonite and gelatine fining and cold static tartaric stabilisation on the mannoprotein content of twowhite wines was studied. All treatments promoted a decrease in the content of mannoproteins. Bentonitefining largely affected the mannoproteins with the highest molecular weight, as did cold static tartaricstabilisation and gelatine fining
Combination of DROOL rules and Protégé knowledge bases in the ONTO-H annotation tool
ONTO-H is a semi-automatic collaborative tool for the semantic annotation of documents, built as a Protégé 3.0 tab plug-in. Among its multiple functionalities aimed at easing the document annotation process, ONTO-H uses a rule-based system to create cascading annotations out from a single drag and drop operation from a part of a document into an already existing concept or instance of the domain ontology being used for annotation. It also gives support to the detection of name conflicts and instance duplications in the creation of the annotations. The rule system runs on top of the open source rule engine DROOLS and is connected to the domain ontology used for annotation by means of an ad-hoc programmed Java proxy
PATRIMÔNIO GEOMORFOLÓGICO EM UNIDADES DE CONSERVAÇÃO: ANÁLISE PRELIMINAR DO “MORRO DO CHAPÉU”, PRUDENTÓPOLIS-PR
O Patrimônio Geomorfológico refere-se às formas de relevo que possuem determinado valor científico, didático, cultural, ecológico ou econômico, podendo ser considerado como um dos componentes da geodiversidade, que se refere à diversidade natural abiótica da superfície terrestre. O presente trabalho pretende fazer uma análise do geomorfossítio Morro do Chapéu, localizado em Prudentópolis (PR) propondo sua inserção na categoria Monumento Natural do Sistema Nacional de Unidades de Conservação
Genetic variants of CYP2C9 and IL-6 on female infertility
AIM: To study the polymorphic variants in CYP2C9*2*3 and the C-174G promoter polymorphism of the IL-6 gene on Infertile Women.BACKGROUND: - Infertility affects 15–20% of couples worldwide. Within the past decades, there has been a steady rise in the treatment of female infertility with several drugs; - The cytochrome P450 (CYP) genes are oxygenases involved in estrogen biosynthesis and metabolism, generation of DNA damaging procarcinogens, and response to anti-estrogen therapies used in female infertility treatments: - Interleukin-6 (IL-6) is a pleiotropic proinflammatory cytokine, highly expressed in the female urogenital tract and reproductive organs. It has been implicated in estrogen metabolism imbalance.N/
VINHOS QUE PENSAM - parte I/III GESTÃO DO VIGOR VEGETATIVO DA VINHA A PARTIR DE SENSORES ATIVOS MUTIESPECTRAIS PRÓXIMOS
Costumo dizer que o projeto “Vinhos
que pensam” nasceu de um aperto
de mão entre a equipa de Agricultura
de Precisão da Universidade
de Évora e a Fundação Eugénio de
Almeida, nasceu sem financiamento
próprio mas com uma visão muito
clara de criar valor social na área da
vitivinicultura Alentejana. Passados 6
anos, julgamos que o conhecimento
produzido é relevante para a atividade
e gestão vitivinícola Alentejana,
no entanto, novas perguntas surgem
todos os anos e dessa forma somos
alimentados na motivação de prosseguir
com este projeto, ao qual, outras
entidades e vontades se vão agora
também associando.
A Agrobótica, muito recentemente,
desafiou-nos a apresentar os resultados
mais relevantes do projeto
“Vinhos que pensam” e com o maior
prazer lhe dissemos que sim, no entanto,
colocou-se-nos um problema,
os resultados mais relevantes, muito
dificilmente caberiam num único artigo,
como tal, decidimos dividir tais resultados em três artigos, este primeiro
mais virado para os aspetos da gestão
do vigor da vegetação da vinha; o segundo
mais virado para os sensores
geoelétricos do solo e sua aplicação na gestão e estudo do solo; e por fim,
um terceiro mais virado para aspetos
da nutrição das plantas considerando
a interação solo/planta e a utilização
dos sensores multiespectrais
Mass, Angular Momentum and Thermodynamics in Four-Dimensional Kerr-AdS Black Holes
In this paper, the connection between the Lorentz-covariant counterterms that
regularize the four-dimensional AdS gravity action and topological invariants
is explored. It is shown that demanding the spacetime to have a negative
constant curvature in the asymptotic region permits the explicit construction
of such series of boundary terms. The orthonormal frame is adapted to
appropriately describe the boundary geometry and, as a result, the boundary
term can be expressed as a functional of the boundary metric, extrinsic
curvature and intrinsic curvature. This choice also allows to write down the
background-independent Noether charges associated to asymptotic symmetries in
standard tensorial formalism. The absence of the Gibbons-Hawking term is a
consequence of an action principle based on a boundary condition different than
Dirichlet on the metric. This argument makes plausible the idea of regarding
this approach as an alternative regularization scheme for AdS gravity in all
even dimensions, different than the standard counterterms prescription. As an
illustration of the finiteness of the charges and the Euclidean action in this
framework, the conserved quantities and black hole entropy for four-dimensional
Kerr-AdS are computed.Comment: 15 pages,no figures,few references added,JHEP forma
Theoretical description of phase coexistence in model C60
We have investigated the phase diagram of the Girifalco model of C60
fullerene in the framework provided by the MHNC and the SCOZA liquid state
theories, and by a Perturbation Theory (PT), for the free energy of the solid
phase. We present an extended assessment of such theories as set against a
recent Monte Carlo study of the same model [D. Costa et al, J. Chem. Phys.
118:304 (2003)]. We have compared the theoretical predictions with the
corresponding simulation results for several thermodynamic properties. Then we
have determined the phase diagram of the model, by using either the SCOZA, or
the MHNC, or the PT predictions for one of the coexisting phases, and the
simulation data for the other phase, in order to separately ascertain the
accuracy of each theory. It turns out that the overall appearance of the phase
portrait is reproduced fairly well by all theories, with remarkable accuracy as
for the melting line and the solid-vapor equilibrium. The MHNC and SCOZA
results for the liquid-vapor coexistence, as well as for the corresponding
critical points, are quite accurate. All results are discussed in terms of the
basic assumptions underlying each theory. We have selected the MHNC for the
fluid and the first-order PT for the solid phase, as the most accurate tools to
investigate the phase behavior of the model in terms of purely theoretical
approaches. The overall results appear as a robust benchmark for further
theoretical investigations on higher order C(n>60) fullerenes, as well as on
other fullerene-related materials, whose description can be based on a
modelization similar to that adopted in this work.Comment: RevTeX4, 15 pages, 7 figures; submitted to Phys. Rev.
Glauber dynamics in a single-chain magnet: From theory to real systems
The Glauber dynamics is studied in a single-chain magnet. As predicted, a
single relaxation mode of the magnetization is found. Above 2.7 K, the
thermally activated relaxation time is mainly governed by the effect of
magnetic correlations and the energy barrier experienced by each magnetic unit.
This result is in perfect agreement with independent thermodynamical
measurements. Below 2.7 K, a crossover towards a relaxation regime is observed
that is interpreted as the manifestation of finite-size effects. The
temperature dependences of the relaxation time and of the magnetic
susceptibility reveal the importance of the boundary conditions.Comment: Submitted to PRL 10 May 2003. Submitted to PRB 12 December 2003;
