The meaning and evolution of the notion of “temperature” (which is a key concept for the condensed and gaseous matter theories) are addressed from different points of view. The concept of temperature has turned out to be much more fundamental than conventionally thought. In particular, the temperature may be introduced for systems built of a “small” number of particles and particles at rest. The Kelvin temperature scale may be introduced into quantum and relativistic physics due to the fact that the efficiency of the quantum and relativistic Carnot cycles coincides with that of the classical one. The relation of temperature with the metrics of the configurational space describing the behavior of systems built from non-interacting particles is demonstrated. The role of temperature in constituting inertia and gravity forces treated as entropy forces is addressed. The Landauer principle asserts that the temperature of a system is the only physical value defining the energy cost of the isothermal erasure of a single bit of information. The fundamental role of the temperature of the cosmic microwave background in modern cosmology is discussed. The range of problems and controversies related to the negative absolute temperature is treated.

AbstractClassical Cepheids form one of the foundations of modern cosmology and the extragalactic distance scale; however, cosmic microwave background observations measure cosmological parameters and indirectly the Hubble Constant, H0, to unparalleled precision. The coming decade will provide opportunities to measure H0 to 2% uncertainty thanks to the Gaia satellite, JWST, ELTs and other telescopes using Cepheids and other standard candles. In this work, we discuss the upcoming role for variable stars and asteroseismology in calibrating the distance scale and measuring H0 and what problems exist in understanding these stars that will feed back on these measurements.

In this paper, we focus on the astrophysical results and the related cosmological implications derived from recent microwave surveys, with emphasis to those coming from the Planck mission. We critically discuss the impact of systematic effects and the role of methods to separate the cosmic microwave background (CMB) signal from the astrophysical emissions and each different astrophysical component from the others. We then review the state-of-the-art diffuse emissions, extragalactic sources, cosmic infrared background and galaxy clusters, addressing the information they provide to our global view of the cosmic structure evolution and for some crucial physical parameters, as the neutrino mass. Finally, we present three different kinds of scientific perspectives for fundamental physics and cosmology offered by the analysis of on-going and future CMB projects at different angular scales dedicated to anisotropies in total intensity and polarization and to absolute temperature.

Basic Anion

This study investigates the synergistic effects of ion exchange and biodegradation methods to remove the Acid Blue 193 also called Gryfalan Navy Blue RL (GNB) dye from wastewater. Ion exchange studies were performed using a strongly basic anion exchange resin Amberlite IRA 400. The equilibrium was characterized by a kinetic and thermodynamic points of view, establishing that the sorption of the GNB dye was subject to the Freundlich isotherm model with R2 = 0.8710. Experimental results showed that the activated resin can removed up to 93.4% when the concentration of dye solution is 5.62�10-2 mM. The biodegradation of the GNB was induced by laccase, an enzyme isolated from white-rot fungus. It was also analyzed the role of pH and dye concentration on GNB biodegradation, so 5�10-2 mM dye had a maximum discoloration efficiency of 82.9% at pH of 4. The laccase showed a very fast and robust activity reaching in a few minutes a Km value of 2.2�10-1mM. In addition, increasing the GNB concentration up to 8�10-1 mM did not triggered a substrat inhibition effect on the laccase activity. Overall, in this study we proposed a mixt physicochemical and biological approach to enhance the GNB removal and biodegradability from the wastewaters and subsequently the environment.

The Impact

As mature neutron stars are cold (on the relevant temperature scale), one has to carefully consider the state of matter in their interior. The outer kilometre or so is expected to freeze to form an elastic crust of increasingly neutron-rich nuclei, coexisting with a superfluid neutron component, while the star’s fluid core contains a mixed superfluid/superconductor. The dynamics of the star depend heavily on the parameters associated with the different phases. The presence of superfluidity brings new degrees of freedom—in essence we are dealing with a complex multi-fluid system—and additional features: bulk rotation is supported by a dense array of quantised vortices, which introduce dissipation via mutual friction, and the motion of the superfluid is affected by the so-called entrainment effect. This brief survey provides an introduction to—along with a commentary on our current understanding of—these dynamical aspects, paying particular attention to the role of entrainment, and outlines the impact of superfluidity on neutron-star seismology.

Abstract Background Oaxaca is one of the most diverse states in Mexico from biological and cultural points of view. Different ethnic groups living there maintain deep and ancestral traditional knowledge of medicinal plants as well as traditional practices and beliefs about diseases/illnesses and cures. Previous ethnobotanical research in this state has helped document this knowledge, but with the addition of more studies, more records appear. We updated the inventory of medicinal knowledge between the different ethnic groups that inhabit the Oaxacan territory. Methods A database was constructed from two sources: (1) original data from a 3-year project in 84 municipalities of Oaxaca inhabited by eight ethnic groups and (2) different electronic databases. Results Records of 1032 medicinal plants were obtained; 164 families were registered, with Asteraceae, Fabaceae, and Rubiaceae being the most commonly used. A total of 770 species were reported in 14 vegetation types; the most important species came from temperate forests. Only 144 species corresponded to introduced species, and 272 were listed in a risk category. Illnesses of the digestive and genitourinary systems as well as culture-bound syndromes were treated with high numbers of medicinal plants. The Mestizo, Mixe, Mixtec, and Zapotec ethnic groups exhibited the greatest number of recorded medicinal plants. The 17 species that were used among almost all ethnic groups in Oaxaca were also used to cure the highest number of diseases. Discussion Inventories of medicinal plants confirm the persistence of traditional knowledge and reflect the need to recognize and respect this cosmovision. Many species are gathered in wild environments. The most important illnesses or diseases recorded in the present inventory are also mentioned in different studies, suggesting that they are common health problems in the rural communities of Mexico. Conclusions Medicinal plants are essential for ethnic groups in Oaxaca. It is necessary to recognize and understand the complex ancestral processes involved in the human-nature interaction and the role of these processes in the conservation of biodiversity and in the survivorship of ethnic groups that have persisted for centuries. Finally, this study serves as a wake-up call to respect those worldviews.

Points Of View

Cultural referents not only designate specific realities of a given culture which do not always exist in another but they are also semantic elements which trigger social representations. By conveying values and points of view about different social groups, cultural referents become linguistic instruments to build stereotypes. These thought patterns are shared by the members of a social or cultural community and act as a filter of reality. The aim of this paper is to study the role of cultural referents in the construction of social stereotypes, focusing on the socio-cognitive universe they evoke. To this end, we have analyzed the translations techniques applied in the Spanish, Catalan and English versions of a novel which has been very successful on the French literary scene: Muriel Barbery’s L’Élégance du hérisson (2006). As show the results of this textual comparison, the explanations, descriptions and additional information observed in target texts do not trigger the same associations as cultural referents do in the source text. Translational approaches are too limited when it comes to achieve linguistic adequacy to different world visions. Therefore, translation must be conceived as an encounter between two cultural systems, in which the translator must build bridges, not so much between two linguistic systems as between the social perceptions and values of two different cultural communities.

This research deals with the question of whether an ecumenical ethics can be developed in South Africa that at least will be applicable in the field of political ethics and that can assist the various ecclesiastical traditions to ‘speak with one voice’ when they address the government on matters of Christian ethical concern. The research rests on the recognition of the variety of ethical persuasions and points of view that flow from the variety of hermeneutical approaches to Scripture. However, within this plethora of ethical discourses, an ‘overlapping’ ethics based on a proposed set of minimum theological ideas can be pursued in order to reach at least an outline of an applicable ecumenical political ethics conducive to the church–state dialogue in South Africa today. The article concludes that a ‘minimum consensus’ on the role of revelation in the moral discourses is possible and is enriched by traditional ideas such as creation and natural law, the reign of God and Christology, and it can provide a suitable common ground for an ecumenical ethics applicable to the moral difficulties in the political domain in South Africa today.

Solving the problems of business growth in modern conditions requires effective management of the ever-increasing system of market relations between business and consumers, partners and other participants in the communication space. The increasing role of marketing communications in resolving motivational and resource contradictions between market participants is substantiated. The influence of various potentials on the formation of sources of effective functioning and business development is indicated. Different points of view regarding communication as a category determining the formation of "confidence" as a tool for managing the competitive position of an enterprise are considered. The nature of communication divergence is revealed in the construction of marketing fields of interacting subjects. The need to consider the interrelationship of different resources (labor, intellectual, communication, cognitive, motivational) as the basic components determining the state of the capital (moral, motivational, marketing-behavioral) formed by the subject is identified. A resource approach to building trust in business is proposed. The influence of organizational culture on the implementation of a positive marketing mimicry of business to the requirements of a competitive market is indicated. The model of the enterprise competitive position management by means of increasing the confidence to business in terms of building the marketing communication field is offered.
