Las formas diversas que la adornan - como sus estalactitas y estalagmitas - la oscuridad, las grandes salas y los estrechos pasajes hacen de este ambiente un mundo maravilloso para curiosos y estudiosos e irresistible para los que buscan la aventura. Por sus características mineralógicas y biológicas, la caverna es un medio frágil y muy delicado que requiere de un estricto plan de manejo para asegurar su preservación. Diversos estudios espeleológicos se llevaron a cabo hasta la década del noventa, pero en los últimos años esta actividad fue interrumpida dando primacía a la explotación turística. En este trabajo se describen las características más sobresalientes de la cavidad y algunas de las teorías más aceptadas sobre su origen

A Triassic tetrapod footprint assemblage from southern South America: Palaeobiogeographical and evolutionary implications
No full textA new Triassic tetrapod track assemblage recorded from levels of the Cuyana Basin (west-central Argentina) is described. The tracks came from multiple track-bearing horizons of the Upper Triassic (Carnian) Portezuelo Formation that indicate recurrent playa to mudflat conditions in a marginal lacustrine succession. This footprint assemblage is the most important one described up to now for the lower Mesozoic of South America, and forms a significant estimate of the fauna represented during that time in the region. Therefore, in order to understand the faunal significance of the assemblage, the track-makers were identified within a phylogenetic context. Although at a coarse taxonomic level, this analysis indicates the presence of non-mammalian therapsids (small cynodonts and large dicynodonts) and a quite diverse archosaur fauna that includes members of both crurotarsal archosaurs and dinosaurs (sauropodomorphs and theropods). Comparisons between the studied assemblage and other Early Mesozoic tetrapod track records from Gondwana suggest close relationships with those described from the Upper Triassic of the Karoo Basin in South Africa. In addition, the presence of putative basal sauropodomorph dinosaur tracks in the Portezuelo levels suggests that the stratigraphic range of the group extends back into the Carnian, farther than that documented by the known body-fossil record of the group in western Gondwana.Fil: Marsicano, Claudia Alicia.

The National Labour Policies in the context of the Europe 2020 strategy and of the European Economic Governance
No full textThe National Labour Policies in the context of the Europe 2020 strategy and of the European Economic Governance, by Silvia Borelli
The author presents the main priorities of the Europe 2020 strategy and the different steps of the European Semester of the European Economic Governance. The system of the European measures to solve the economic crisis is completed by the analysis of the “Six Pack”, the EuroPlus Pact and the Treaty on Stability, Coordination and Governance. The author clarifies how the European Employment Strategy has been fully absorbed by the European Economic Governance. After considering some of the new European economic framework’s consequences on Member States’ labour policies and on social dialogue, the author focuses on the recent review of Italian labour policies, performed by European Commission as part of the European Semester

Experiential verbs in Homeric Greek
No full textIn Experiential verbs in Homeric Greek. A constructional approach Silvia
Luraghi offers a comprehensive account of construction variation with
two-place verbs belonging to different sub-domains of experience
(including bodily sensation, perception, cognition, emotion and
volitionality) in the Homeric language. Traditionally, variation is
ascribed to the independent meaning of cases that mark the second
argument, and explanations have focused on properties of the latter.
By taking a constructional approach, the author shows that construction
variation also brings about differences in the conceptualization of the
subject/experiencer by pointing to different degrees of control and
awareness. Variation is then shown to refl ect the embodied construal
of experience along with the social dimension of emotion
Immobilized short peptides chromatography applied to therapeutic antibodies purification
No full textLos anticuerpos monoclonales (mAbs) tienen un enorme y creciente interés en la industria farmacéutica. Actualmente hay más de 70 mAbs terapéuticos aprobados por la Food and Drug Administration (FDA). Su proceso de producción industrial consiste en una etapa de crecimiento de las células productoras del mAb en un biorreactor y en una etapa de recuperación y purificación del mAb a partir del caldo de cultivo celular. La cromatografía de afinidad (AC) con proteína A inmovilizada es el método de elección para su purificación. Ésta se basa en un reconocimiento molecular entre la proteína de interés y la proteína A inmovilizada sobre un soporte. Sin embargo, las matrices con proteína A inmovilizada son costosas, de baja capacidad, lábiles y de corta vida útil. Las desventajas de la proteína A han incentivado el desarrollo de métodos de purificación alternativos con péptidos cortos sintéticos (entre 5 y12 aminoácidos) como ligandos de afinidad. Éstos son ideales para separaciones industriales por afinidad ya que pueden ser producidos a un costo muy inferior a los ligandos proteicos y en forma aséptica bajo normas GMP. A su vez, son mucho más estables porque no requieren de una estructura terciaria específica para mantener su actividad biológica y las interacciones entre los péptidos y las proteínas son generalmente moderadas, lo que resulta en condiciones suaves de elución. La presente revisión describe:1. El desarrollo de ligandos peptídicos con afinidad por anticuerpos; 2. La síntesis y evaluación de soportes de afinidad con ligandos peptídicos inmovilizados; y 3. Las aplicaciones de las matrices de afinidad con péptidos inmovilizados en la purificación de anticuerpos.Monoclonal antibodies (mAbs) have an enormous and growing interest in the pharmaceutical industry. Currently, there are more than 70 therapeutic mAbs approved by the Food and Drug Administration (FDA). Its industrial production process consists of a first step of growing the mAb-producing cells in a bioreactor and a step of recovering and purifying the mAb from the cell culture broth. Affinity chromatography (AC) with immobilized protein A is the method of choice for their purification. Itis based on a molecular recognition between the antibody and protein A immobilized on a support. However, matrices with immobilized protein A are expensive, with low capacity, labile and of shorthalf-life. The disadvantages of protein A have encouraged the development of alternative purification methods with synthetic short peptides (from 5 to 12 amino acids) as affinity ligands. Peptides are ideal for affinity industrial separations since they can be synthesized at lower cost than proteins and in an aseptic way under GMP standards. Furthermore, they are much more stable because they do not require a specific tertiary structure to maintain their biological activity. Also, interactions between peptides and proteins are generally moderate, resulting in mild elution conditions. The present review describes the development of peptide ligands with affinity for antibodies, the synthesis and evaluation of affinity supports with immobilized peptide ligands and the applications of affinity matrices with immobilized peptides to antibodies purification.Fil: Barredo, Gabriela Romina.

Does strict employment protection discourage job creation? Evidence from Croatia
No full textEmployment protection legislation in Croatia is among the most strict in Europe. Firing is difficult and costly, and flexible forms of employment are limited. Is this apparent rigidity reflected-as one would expect based on standard economic theory-in low labor market dynamics? Is job creation low and hiring limited? Is the job security of insiders achieved at the cost of outsiders not being able to enter thelabor market? The author attempts to answer these questions by examining job flows. If the employment protection legislation is binding, then job and worker turnover should be low. He shows that this is indeed the case. Hiring is limited and the average job tenure is very long in Croatia. Job destruction is low, however job creation is still lower. The result is accumulation of unemployment, in large part due to new labor market entrants not being able to find a job. The high degree of job protection also seems to strengthen the bargaining position of insiders and results in relatively high wages. So, wages in Croatia are higher than among its competitors, even after adjusting for productivity. These high labor costs are likely to contribute to limited job creation in existing firms, but also are likely to discourage the entry of-and thus job creation in-new firms. The author presents evidence that firm growth has been indeed limited in Croatia, contributing to the low employment level. The author examines other potential causes of high unemployment in Croatia (the unemployment benefit system, labor taxation, the wage structure, and skill and spatial mismatches). He argues that they do not play a substantial part in accounting for poor labor market outcomes in Croatia. The author concludes that the stringent employment protection legislation is the key labor market institution behind low job creation and high unemployment. Based on this he recommends specific measures aimed at liberalizing the labor market to foster job creation and employment.Labor Management and Relations,Labor Policies,Labor Markets,Environmental Economics&Policies,Trade Finance and Investment,Labor Markets,Labor Management and Relations,Labor Standards,Banks&Banking Reform,Environmental Economics&Policies
A interação texto/imagem em duas traduções de Flicts para o inglês
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Estudos da Tradução, Florianópolis, 2013.Abstract : This study aims to investigate two translations of FLICTS, first children's book written by Ziraldo and first full-colored album for children produced in Brazil, with a view to discussing the different interactions between text and image that might occur within the translation of children's literature. Considered a landmark in Brazilian Children's Literature since its launch in 1969, its British version was translated by Silvia Caruana and published by the publishing house Roger Schlesinger in 1973 and its American English version was translated by Daniela Pinto, originally published by Melbooks in 1984 - subsequently also published by Editora Melhoramentos and commercialized in Brazil. The theoretical framework informing the study is based on the interface of Descriptive Translation Studies, Translation of Children's Literature and the Grammar of Visual Design. By the analyses of a multimodal corpus and a dossier about the history of this printed book, it was possible to note that the several changes along FLICTS publishing history have made up other possible readings on this work
