O COMÉRCIO BRASILEIRO DE CARNE SUÍNA E O POTENCIAL EXPORTADOR MEDIANTE ELIMINAÇÃO DE BARREIRAS EXTERNAS
Get PDFEste estudo analisa o panorama e o potencial exportador do setor brasileiro de carne suína frente à suposição de futuros acordos de liberalização multilateral ou por integração econômica entre o Brasil e determinados blocos/países. Para analisar o panorama e o potencial exportador do setor de carne suína, desenvolvem-se quatro generalizações metodológicas: o potencial importador dos blocos/países, o cálculo da evolução do Índice de Vantagem Revelada das Exportações do Brasil e de seus principais concorrentes no interior de cada bloco, pesquisa bibliográfica das principais barreiras existentes e cálculo do Índice de Orientação Regional. Os resultados, quanto ao potencial importador, indicam que a União Européia (UE) e a Comunidade dos Estados Independentes (CEI) constituem-se em mercado potencial e promissor para a carne suína, respectivamente. Os resultados do cálculo das vantagens comparativas revelaram que o Brasil tem competitividade crescente no setor de carne suína para o período 1990 a 2005. Quanto aos concorrentes no interior de cada bloco ou país, a União Européia é que apresentou o maior concorrente. Quanto às barreiras impostas, estas revelaram ser, de um modo geral, extremamente elevadas e, em alguns casos, impeditivas, com destaque para o NAFTA, Japão e UE. Portanto, o setor brasileiro de carne suína teria muito a ganhar caso fossem eliminadas tais barreiras. Enfim, na última relação, constata-se alto grau de aceitação das exportações brasileiras de carne suína àqueles blocos que não têm barreiras sanitárias impeditivas, com destaque para o CEI. Contudo, ao cruzar os resultados para o setor, observa-se que, a partir da efetivação de acordos de livre comércio inter-regionais ou multilaterais, com os blocos ou países em estudo, estes trarão ganhos potenciais efetivos para o setor brasileiro de carne suína. --------------------------------------------This study makes an analysis of the Brazilian pork sector panorama and its export potential forefront the supposition of future agreements of multilateral liberalization or by the economic integration between Brazil and certain blocks/Countries. To analyze the panorama and the export potential from the pork sector, four methodological generalizations were developed: the importing potential of those blocks/Countries, the calculation of the revealed advantage index evolution of Brazilian exportations and of its main competitors inside each block, bibliographical research of the main existing barriers and the Regional Orientation Index calculation. The results considering the importing potential indicate that the European Union (EU) and the Commonwealth of Independent States (CIS) respectively constitute a potential and promising market to Brazilian pork sector. The results from the calculation of the comparative advantages demonstrated that Brazil has an increasing competitiveness in the pork sector in the period between 1990 and 2005. As far as the competitors inside each block or country, the European Union was the one that presented the major competitor. In relation to the imposed barriers, they demonstrated to be, in general, extremely high and, in some cases, impeditive with a highlight to NAFTA, Japan and EU. Therefore, the Brazilian pork sector has much to benefit if such barriers were eliminated. Finally, to the last relation, we can perceive a high level of acceptance to the exportations of the Brazilian pork market to those blocks that do not have impeditive sanitary barriers, with an especial emphasis to CIS. However, while tabling the results we can observe that, from the accomplishment of inter-regional and multilateral free trade agreements with the blocks or countries that were subject of this study, these will bring potential effective advantages to the Brazilian pork sector.comércio potencial, barreiras comerciais, carne suína, commerce potential, commercial barriers, pork, International Relations/Trade, Livestock Production/Industries,
O comércio potencial brasileiro de carne bovina no contexto de integração regional
Get PDFThis study analyses the Brazilian beef exportation potential considering the supposition of future agreements of regional integration. The countries or blocks that were chosen are The European Union (EU), the North American Free Trade Agreement (NAFTA) countries, the Commonwealth of Independent States, the Popular Republic of China (PRC) and Japan. To analyze the meat sector exportation potential, four methodological generalizations are developed: the importing potential of the mentioned countries, the calculus of the evolution in the Revealed Advantage Index of Brazilian exportations and its main competitors, bibliographical research of the main existing trade barriers and the calculus of the Regional Orientation Index. The results concerning the importing potential indicate that the European Union (EU) consists of a very attractive market to Brazilian beef. The results of the calculus of comparative advantages reveal that Brazil has a higher competitivity in meat sector and it increasing in the period between 1990 and 2003. When considering the competitors inside each block or country, the European Union shows up as the major competitor. As far as the imposed trade barriers, these come out, in a general way, as extremely high and sometimes representing a blockage. Thus, the Brazilian meat sector would be largely improved if these barriers were eliminated. Finally, on the last relation, we can verify the high level of acceptance of Brazilian beef exportation to those blocks that do not have impeditive sanitary barriers. Nevertheless, when crossing the results obtained to the sector one can observe that from the accomplishment of inter-regional free trade agreements, via Mercosur or through bilateral agreements with the blocks or countries considered in this study, would bring real profits to the Brazilian meat sector.Potential trade, regional integration, beef., Agribusiness, F13, F15.,
Metainferential Paraconsistency
Get PDFIn this article, our aim is to take a step towards a full understanding of the notion of paraconsistency in the context of metainferential logics. Following the work initiated by Barrio et al (2018), we will consider a metainferential logic to be paraconsistent whenever the metainferentialversion of Explosion (or meta-Explosion) is invalid. However, our contribution consists in modifying the definition of meta-Explosion by extending the standard framework and introducing a negation for inferences and metainferences. From this new perspective, Tarskian paraconsistent logics such asLP will not result to be metainferentially paraconsistent, in contrast to, for instance, non-transitive logics like ST. Finally, we will end up by defining a logic which is metainferentially paraconsistent in every level, and discussing whether this logic is uniform through translations.Fil: Da Re, Bruno.

The importance of early arthroscopy in athletes with painful cartilage lesions of the ankle: a prospective study of 61 consecutive cases
Get PDFBACKGROUND
Ankle sprains are common in sports and can sometimes result in a persistent pain condition.
PURPOSE
Primarily to evaluate clinical symptoms, signs, diagnostics and outcomes of surgery for symptomatic chondral injuries of the talo crural joint in athletes. Secondly, in applicable cases, to evaluate the accuracy of MRI in detecting these injuries. Type of study: Prospective consecutive series.
METHODS
Over around 4 years we studied 61 consecutive athletes with symptomatic chondral lesions to the talocrural joint causing persistent exertion ankle pain.
RESULTS
43% were professional full time athletes and 67% were semi-professional, elite or amateur athletes, main sports being soccer (49%) and rugby (14%). The main subjective complaint was exertion ankle pain (93%). Effusion (75%) and joint line tenderness on palpation (92%) were the most common clinical findings. The duration from injury to arthroscopy for 58/61 cases was 7 months (5.7–7.9). 3/61 cases were referred within 3 weeks from injury. There were in total 75 cartilage lesions. Of these, 52 were located on the Talus dome, 17 on the medial malleolus and 6 on the Tibia plafond. Of the Talus dome injuries 18 were anteromedial, 14 anterolateral, 9 posteromedial, 3 posterolateral and 8 affecting mid talus. 50% were grade 4 lesions, 13.3% grade 3, 16.7% grade 2 and 20% grade 1. MRI had been performed pre operatively in 26/61 (39%) and 59% of these had been interpreted as normal. Detection rate of cartilage lesions was only 19%, but subchondral oedema was present in 55%. At clinical follow up average 24 months after surgery (10–48 months), 73% were playing at pre-injury level. The average return to that level of sports after surgery was 16 weeks (3–32 weeks). However 43% still suffered minor symptoms.
CONCLUSION
Arthroscopy should be considered early when an athlete presents with exertion ankle pain, effusion and joint line tenderness on palpation after a previous sprain. Conventional MRI is not reliable for detecting isolated cartilage lesions, but the presence of subchondral oedema should raise such suspicion
Public experiences of mass casualty decontamination
Get PDFIn this article, we analyze feedback from simulated casualties who took part in field exercises involving mass decontamination, to gain an understanding of how responder communication can affect people’s experiences of and compliance with decontamination. We analyzed questionnaire data gathered from 402 volunteers using the framework approach, to provide an insight into the public’s experiences of decontamination and how these experiences are shaped by the actions of emergency responders. Factors that affected casualties’ experiences of the econtamination process included the need for greater practical information and better communication from responders, and the need for privacy. Results support previous findings from small-scale incidents that involved decontamination in showing that participants wanted better communication from responders during the process of decontamination, including more practical information, and that the failure of responders to communicate effectively with members of the public led to anxiety about the decontamination process. The similarity between the findings from the exercises described in this article and previous research into real
incidents involving decontamination suggests that field exercises provide a useful way to examine the effect of responder communication strategies on the public’s experiences of decontamination. Future exercises should examine in more detail the effect of various communication strategies on the public’s experiences of decontamination. This will facilitate the development of evidence-based communication strategies intended to reduce anxiety about decontamination and increase compliance among members of the public during real-life incidents that involve mass decontamination
Beam Studies of the Segmented Resistive WELL: a Potential Thin Sampling Element for Digital Hadron Calorimetry
Full text linkThick Gas Electron Multipliers (THGEMs) have the potential of constituting
thin, robust sampling elements in Digital Hadron Calorimetry (DHCAL) in future
colliders. We report on recent beam studies of new single- and
double-THGEM-like structures; the multiplier is a Segmented Resistive WELL
(SRWELL) - a single-faced THGEM in contact with a segmented resistive layer
inductively coupled to readout pads. Several 1010 cm configurations
with a total thickness of 5-6 mm (excluding electronics) with 1 cm pads
coupled to APV-SRS readout were investigated with muons and pions. Detection
efficiencies in the 98 range were recorded with average pad-multiplicity of
1.1. The resistive anode resulted in efficient discharge damping, with
potential drops of a few volts; discharge probabilities were for
muons and for pions in the double-stage configuration, at rates
of a few kHz/cm. Further optimization work and research on larger detectors
are underway.Comment: Presented at the Vienna Conference on Instrumentation,

Far-UV HST Spectroscopy of an Unusual Hydrogen-poor Superluminous Supernova: SN2017egm
Get PDFSN2017egm is the closest (z = 0.03) H-poor superluminous supernova (SLSN-I) detected to date, and a rare example of an SLSN-I in a massive, metal-rich galaxy. We present the HST UV and optical spectra covering 1000–5500 Å, taken at +3 day relative to the peak. Our data reveal two absorption systems at redshifts matching the host galaxy NGC 3191 (z = 0.0307) and its companion galaxy (z = 0.0299) 73'' apart. Weakly damped Lyα absorption lines are detected at these two redshifts, with H i column densities of (3.0 ± 0.8) × 1019 and (3.7 ± 0.9) × 1019 cm−2, respectively. This is an order of magnitude smaller than the H i column densities in the disks of nearby galaxies (>1010 M ⊙) and suggests that SN2017egm is on the near side of NGC 3191 and has a low host extinction (E(B − V) ~ 0.007). Using unsaturated metal absorption lines, we find that the host of SN2017egm probably has a solar or higher metallicity and is unlikely to be a dwarf companion to NGC 3191. Comparison of early-time UV spectra of SN2017egm, Gaia16apd, iPTF13ajg, and PTF12dam finds that the continuum at λ > 2800 Å is well fit by a blackbody, whereas the continuum at λ < 2800 Å is considerably below the model. The degree of UV suppression varies from source to source, with the 1400–2800 Å continuum flux ratio of 1.5 for Gaia16apd and 0.4 for iPTF13ajg. This cannot be explained by the differences in magnetar power or blackbody temperature. Finally, the UV spectra reveal a common set of seven broad absorption features and their equivalent widths are similar (within a factor of 2) among the four events
Classical limit of the Casimir entropy for scalar massless field
Full text linkWe study the Casimir effect at finite temperature for a massless scalar field
in the parallel plates geometry in N spatial dimensions, under various
combinations of Dirichlet and Neumann boundary conditions on the plates. We
show that in all these cases the entropy, in the limit where energy
equipartitioning applies, is a geometrical factor whose sign determines the
sign of the Casimir force.Comment: 14 page
Responsabilidade: sobre a consciência moral e a alteridade no pensamento de Viktor Frankl e Emmanuel Levinas
Get PDFResponsibility is the term connection between the thought of Emmanuel Levinas and Viktor Frankl, by which is consistent moral consciousness as a possible encounter with another human. Freedom and responsibility before any deliberate or intentional subject, in which the respondent by human indigence of another Master who reports to break the monism of a strong bio psyche and sociology, whose predominant aspect is the person in charge of any condition. Consciousness previous intelligibility while Bad conscience that does not close in a circularity of Even, putting into crisis selfhood and meaning to be found and updated in meetings and confrontation with the social meanings. Encounters through the traces inscribed in face epiphenomenon of the other's presence and Absent, the "He" that is the otherness that recognizes the other in its absolute say. Pronounceable say the flow of time in sensitivity brought to disinterestedness and input Others meeting as anarchical and dissymmetry, causing the other the trauma of what would be the obvious. Meaning of life post as liability prior to any free initiative of the subject, which collects on the Other traces of the third, the "He" look like infinitive - face that speaks to me, I want the clutter in your selfhood, and exposes the human to justice before the others, absolutely another. Confrontation with the responsibility of nakedness and misery of Others, which calls for the unity of the one- respondent, taking him hostage in unconditional replacement source of appeal arising from (Illeité) – “he-ity” and calls for replacement, give support to the less is more, the infinite in ethical language.Responsabilidade é o termo de ligação entre o pensamento de Viktor Frankl e Emmanuel Levinas, pelo qual se coaduna a consciência moral como possibilidade de encontro com o outro humano.
