Thermostatic properties of Seyler-Blanchard nuclei

This work aim to study the various thermal characteristics of nuclei in view of the saturation and critical behavior of infinite nuclear matter. The free energy of a nucleus is parametrized using the density and temperature-dependent liquid-drop model and interaction among nucleons is worked out within the effective relativistic mean-field theory (E-RMF). The effective mass (m, * ) and critical temperature of infinite symmetric nuclear matter (Tc) of a given E-RMF parameter force play a seminal role in the estimation of thermal properties. A larger (m * ) and Tc of the E-RMF set estimate larger excitation energy, level density, and limiting temperature (T l ) for a given nucleus. The limiting temperature of a nucleus also depends on the behavior of the nuclear gas surrounding the nucleus, making the equation of state (EoS) at subsaturation densities an important input. A stiff EoS in the subsaturation region estimates a higher pressure of the nuclear gas making it less stable. Since the Tc plays an important part in these calculations, we perform a Pearson correlation statistical study of fifteen E-RMF parameter sets, satisfying the relevant constraint on EoS. Effective mass seems to govern the thermal characteristics of infinite as well as finite nuclear matter in the framework of E-RMF theory.

“…Em Portugal, existe uma forte ligação entre o turismo de saúde e bem -estar e as estâncias termais, desde a sua origem, assumindo -se estas últimas um posicionamento nodal deste segmento. Diversos autores(Quintela, 2004; Ramos, 2005; Fernandes; Fernandes, 2008;Medeiros; Cavaco, 2008; Alpoim, 2010) têm estudado a evolução do turismo de saúde e bem -estar em Portugal, mais especificamente do termalismo. Com efeito, o país apresenta uma natureza hidrográfica caracterizada por uma rede de águas com numerosas propriedades e ricamente mineralizadas, como são os casos das fontes minerais, rios e albufeiras.…”

Turismo de Saúde e Bem-Estar-Para uma estratégia de desenvolvimento local: o caso português, apresenta uma reflexão sobre a nova e redimensionada (re)interpretação do termalismo em Portugal. Entremeando uma visão holística do produto estratégico "Turismo de Saúde e Bem-Estar" com a exemplificação a nível do case study-estâncias termais em portugal-, consubstancia-se uma nova proposta de modelo de gestão estratégica do destino turístico, por forma a identificar o contributo do turismo termal para um desenvolvimento local. Salienta-se, assim, o turismo de health and wellness em Portugal, pese embora as suas diferenciações regionais, como congregador de fatores que perpassam o desenvolvimento de um health and wellness destination, o desenvolvimento de health and wellness facilities, a que se soma a tradição e experiência das estâncias termais e a afirmação, hoje, de uma oferta competitiva. O estudo resulta num ato de procura e documentada identificação das estratégias e modelos de gestão seguidos pelas boas práticas internacionais e nacionais de turismo de saúde e bem-estar, não perdendo de vista os destinos concorrentes que possuem, ao fim ao cabo, uma oferta similar Acresce ainda um estudo empírico do perfil e hábitos de consumo do turista de Saúde e Bem-Estar respaldado no estudo de caso, o que possibilitou lograr o sentido das motivações, comportamentos, perceções e satisfação daquele e, igualmente, delinear uma estratégia de desenvolvimento para o termalismo assente nos pilares da sustentabilidade, qualidade, inovação e competitividade. Palavras-chave: Turismo de saúde e bem-estar; Desenvolvimento local; Competitividade; Sustentabilidade e termalismo. Health and wellness tourism as a local development factor: an analysis of the portuguese thermal and mineral springs Abstract: Health and Wellness Tourism-For a local development strategy: the Portuguese case, it presents a reflection on the new and re-dimensioned (re) interpretation of the thermalism in Portugal. Interviewing a holistic vision of the strategic product " Health and Wellness Tourism " with the exemplification at the level of the case study-thermal and mineral springs in Portugal-, a new proposal of a model of strategic management of the tourist destiny is consubstantiated, in order to identify the contribution of thermal tourism to local development. It should be emphasized, therefore, the health and wellness tourism in Portugal, despite its regional differences, as a pool of factors that permeate the development of a health and wellness destination, the development of wellness facilities, in addition to the tradition and experience of the spas and the affirmation, today, of a competitive offer. The study results in an act of searching and documented identification of the strategies and management models followed by the international and national good practices of health and wellness tourism, not losing sight of the competing destinations that have, after all, a similar offer In addition, there is an empirical study of the profile and consumption h...

Properties of nuclear pastas

In this Review we study the nuclear pastas as they are expected to be formed in neutron star cores. We start with a study of the pastas formed in nuclear matter (composed of protons and neutrons), we follow with the role of the electron gas on the formation of pastas, and we then investigate the pastas in neutron star matter (nuclear matter embedded in an electron gas). Nuclear matter (NM) at intermediate temperatures (1 MeVT 15 MeV), at saturation and sub-saturation densities, and with proton content ranging from 30% to 50% was found to have liquid, gaseous and liquid-gas mixed phases. The isospin-dependent phase diagram was obtained along with the critical points, and the symmetry energy was calculated and compared to experimental data and other theories. At low temperatures (T 1 MeV) NM produces crystal-like structures around saturation densities, and pasta-like structures at sub-saturation densities. Properties of the pasta structures were studied with cluster-recognition algorithms, caloric curve, the radial distribution function, the Lindemann coefficient, Kolmogorov statistics, Minkowski functionals; the symmetry energy of the pasta showed a connection with its morphology.Neutron star matter (NSM) is nuclear matter embedded in an electron gas. The electron gas is included in the calculation by the inclusion of an screened Coulomb potential. To connect the NM pastas with those in neutron star matter (NSM), the role the strength and screening length of the Coulomb interaction have on the formation of the pastas in NM was investigated. Past was found to exist even without the presence of the electron gas, but the effect of the Coulomb interaction is to form more defined pasta structures, among other effects. Likewise, it was determined that there is a minimal screening length for the developed structures to be independent of the cell size.Neutron star matter was found to have similar phases as NM, phase transitions, symmetry energy, structure function and thermal conductivity. Like in NM, pasta forms at around T ≈ 1.5 MeV, and liquid-to-solid phase changes were detected at T ≈ 0.5 MeV. The structure function and the symmetry energy were also found to depend on the pasta structures. Contents I. IntroductionA. The pasta B. The pasta in nuclear matter and in neutron star matter II.
