O impacto da implementa����o do Basel III no capital dos bancos portugueses

Este trabalho �� uma an��lise dos efeitos da implementa����o das ��ltimas recomenda����es do Basel Committee on Banking Supervision (BCBS) tamb��m conhecidas como o Basel III de 2010 que dever��o ser faseadamente implementadas desde 1 de Janeiro de 2013 at�� 1 de Janeiro de 2019, no capital pr��prio dos bancos Portugueses. Neste trabalho assume-se que os ativos pesados pelo risco de 2012 mant��m-se constantes e o capital ter�� de ser aumentado segundo as recomenda����es ano ap��s ano at�� ao fim de 2018. Com esta an��lise, pretende-se entender o n��vel de robustez do capital pr��prio dos bancos Portugueses e se os mesmos t��m capital e reservas suficientes para satisfazer as recomenda����es de capital m��nimo sugeridas pelo BCBS ou caso contr��rio, se necessitar��o de novas inje����es de capital ou ter��o de reduzir a sua atividade econ��mica. O Basel III ainda n��o foi implementado em Portugal, pois a Uni��o Europeia est�� no processo de desenvolvimento e implementa����o do Credit Requirement Directive IV (CRD IV) que �� uma recomenda����o que todos os bancos centrais dos pa��ses da zona Euro dever��o impor aos respetivos bancos. Esta diretiva da Uni��o Europeia �� baseada totalmente nas recomenda����es do Basel III e dever�� ser implementada em 2014 ou nos anos seguintes. At�� agora, os bancos Portugueses seguem um sistema com base no aviso 6/2010 do Banco de Portugal que recomenda o c��lculo dos r��cios core tier 1, tier 1 e tier 2 usando o m��todo nota����es internas (IRB) de avalia����o da exposi����o do banco aos riscos de cr��dito, operacional, etc. e onde os ativos ponderados pelo risco s��o calculados como 12,5 vezes o valor dos requisitos totais de fundos calculados pelo banco. Este m��todo �� baseado nas recomenda����es do Basel II que ser��o substitu��das pelo Basel III. Dado que um dos principais motivos para a crise econ��mica e financeira que assolou o mundo em 2007 foi a acumula����o de alavancagem excessiva e gradual eros��o da qualidade da base do capital pr��prio dos bancos, �� importante analisar a posi����o dos bancos Portugueses, que embora n��o sejam muito grandes a n��vel global, controlam a economia do pa��s. Espera-se que com a implementa����o das recomenda����es do Basel III n��o haja no futuro uma repeti����o dos choques sist��micos de 2007. Os resultados deste estudo usando o m��todo padr��o recomendado pelo BCBS mostram que de catorze bancos Portugueses inclu��dos neste estudo, apenas seis (BES, Montepio, Finantia, BIG, Invest e BIC) conseguem enquadrar nas recomenda����es m��nimas do Basel III at�� 1-1- 2019 e alguns outros est��o marginalmente abaixo dos r��cios m��nimos (CGD, Ita�� e Cr��dito Agr��cola).

Voltammetric oxidation of drugs of abuse III. Heroin and metabolites

The oxidative behavior of heroin in aqueous solution is reported. In order to identify its oxidation peaks, several metabolites, 6-monoacetylmorphine, 3-monoacetylmorphine and norheroin, were synthesized and their electrochemical behavior studied using differential pulse voltammetry. The anodic waves observed for heroin correspond to the oxidation of the tertiary amine group and its follow-up product (secondary amine), and to the oxidation of the phenolic group obtained from hydrolysis, at alkaline pHs, of the 3-acetyl group. The results enabled a new oxidative mechanism for heroin to be proposed in which a secondary amine, norheroin, and an aldehyde are obtained. The voltammetric behavior of 6-monoacetylmorphine and morphine was found to be similar demonstrating that the presence of an acetyl substituent on the 6-hydroxy group does not have a relevant influence on the peak potential of the wave resulting from oxidation of the 3-phenolic group.

Contributions �� la Pal��ontologie du Mioc��ne moyen continental du Bassin du Tage. III - Mammif��res - P��voa de Santar��m, P��ro Filho et Ch��es (Secorio). Conclusions g��n��rales

This study on middle Miocene mammalian faunas from Tagus'basin deals particularly with some small mammals hitherto undescribed from Portugal, including a new Glirid (Paraglirulus scalabicensis nov. sp.); it allows an accurate datation by biostratigraphical standards, Megacricetodon crusafonti, Fahlbuschia darocensis, Cricetodon jotae being characteristic of mammalian MN6 unit, thus their age is nearly that of Sansan and Manchones (however the presence of Peridyromys hamadryas and Lagopsis verus do suggest, amidst this biozone, a somewhat later age than Sansan's); it contributes with indirect correlation data with marine formations, as underlying oyster-bearing beds most probably are in correspondance to the apogee of the same transgression that deposed near Lisbon ���schlier" facies from VI-a division (Serravalian, Blow's zones 10-13, Globorotalia meyeri zone); the diversity of mammalian assemblages is surely related to an environement with varied biotopes, whose characterisation becomes easier if account is taken of the preceding papers on mollusks (G. Truc) and Cyprinid fishes (J. Gaudant), and also according to some unpublished paleobotanical data (J. Pais). A table with a synthesis of all paleontological data so far known is presented.

Halogen-bonded tris (2,4-Bis(trichloromethyl)-1,3,5,triazapentadienato)-M(III) [M = Mn, Fe, Co] complexes and their catalytic activity in the peroxidative oxidation of 1-phenylethanol to acetophenone

One-pot template condensation of CCl3C=N with ammonia on a metal source [MnCl2 center dot 4H(2)O, FeCl3 center dot 6H(2)O or Co(CH3COO)(2)center dot 4H(2)O] in DMSO led to the formation of tris(2,4-bis(trichloromethyl)-1,3,5-triazapentadienato)-M(III) complexes, [M(NH=C(CCl3)NC(CCl3)=-NH}(3)]center dot n(CH3)(2)SO [M = Mn, n = 1 (1); M = Fe, n = 2 (2); M = Co, n = 2 (3)1, which were characterized using elemental analysis, and IR, ESI-MS and single-crystal X-ray analysis. The role of inter- and intramolecular non-covalent halogen and hydrogen bonds in the synthesis of 1-3 is discussed. It is shown that the crystal ionic radii of the metal ions [68.5 (Co) < 69 (Fe) < 72 (Mn), pm] are related to the corresponding Cl center dot center dot center dot Cl distances [3.178 (3) > 3.155 (2) > 3.133 (1) Al. Compounds 1-3 and the related di(triazapentadienato)-Cu(v) complex [Cu(NH=C(CCl3)NC(CCl3)=NH}2]center dot 2(CH3)(2)SO (4) act as catalyst precursors for the additive-free microwave (MW) assisted homogeneous oxidation of 1-phenylethanol with tert-butylhydroperoxide (TBHP), leading to the formation of acetophenone with yields up to 99% and TONs up to 5.0 x 10(3) after 1 h of low power (10 W) MW irradiation.

Mode III interlaminar fracture of carbon/epoxy laminates using the edge crack torsion (ECT) test

The mode III interlaminar fracture of carbon/epoxy laminates was evaluated with the edge crack torsion (ECT) test. Three-dimensional finite element analyses were performed in order to select two specimen geometries and an experimental data reduction scheme. Test results showed considerable non-linearity before the maximum load point and a significant R-curve effect. These features prevented an accurate definition of the initiation point. Nevertheless, analyses of non-linearity zones showed two likely initiation points corresponding to GIIIc values between 850 and 1100 J/m2 for both specimen geometries. Although any of these values is realistic, the range is too broad, thus showing the limitations of the ECT test and the need for further research.

Dynamics of transmission of Trypanosoma cruzi in a rural area of Argentina: III. Persistence of T. cruzi parasitemia among canine reservoirs in a two-year follow-up

A new cross-sectional survey of household- associated mongrel dogs as well as follow-up of previously parasitemic individuals was carried out in 1984 toy means of xenodiagnosis and serologic techniques to get a deeper insight into the relationship of T. cruzi parasitemia and age among canine hosts in a rural area of Argentina. Persistence of detectable parasitemia was age-independent, or at most, loosely related to age, confirming the pattern observed in 1982. Similarly no significant age-decreasing effect was recorded among seropositive dogs in: a) the probability of detecting parasites in a 2-year follow-up; b) their intensity of infectiousness (=infective force) for T. infestans 3rd-4th instar nymphs, as measured by the percentage of infected bugs observed in each dog xenodiagnosis. Moreover, not only was the infective force of seropositive dogs for bugs approximately constant through lifetime, but it was significantly higher than the one recorded for children in the present survey, and for human people by other researchers. Therefore, and since T. infestans field populations show high feeding frequencies on dogs, the latter are expected to make the greatest contribution to the pool of infected vectors in the rural household of Argentina. This characteristic should be sufficient to involve canine reservoirs definitely as a risk factor for human people residing in the same house. The increased severity of parasitemia observed among dogs in this survey may be related to the acute undernutrition characteristic of canine populations of poor rural areas in our country, which is expected to affect the ability of the host to manage the infection.

Indicadores das condi����es nutricionais na regi��o do Polonoroeste: III. Estudo cl��nico nutricional

O estudo do exame cl��nico-nutricional �� parte do Inqu��rito Nutricional, realizado no "Diagn��stico em Sa��de do Polonoroeste-MT em 1983". No intuito de reconhecer a situa����o nutricional da popula����o da regi��o em estudo, o grupo do Inqu��rito Nutricional procedeu ao estudo do Consumo Alimentar das fam��lias, ao estudo dos dados antropom��tricos e de sinais cl��nico-nutricionais de crian��as na faixa et��ria de 3 a 72 meses. Foram examinadas 585 crian��as da amostra como proposta por SANCHES &amp; CARVALHEIRO7 adaptado por MEIRELLES e SANCHES. O exame cl��nico-nutricional foi realizado segundo a metodologia recomendada por JELLIFFE4. Foram encontrados sinais cl��nicos sugestivos de car��ncia nutricional em 6,6% das crian��as; sinais de anemia em 9,7% e de b��cio em 2,7%. N��o foi poss��vel definir com precis��o outros quadros carenciais.

Leishmaniose cut��nea experimental. III- Aspectos histopatol��gicos do comportamento evolutivo da les��o cut��nea produzida em Cebus apella (Primates: Cebidae) por Leishmania (Viannia) lainsoni, L. (V.) braziliensis e L. (Leishmania) amazonensis

Estudaram-se os aspectos histopatol��gicos relativos �� evolu����o da infec����o experimental produzida em Cebus apella (Primates: Cebidae) por Leishmania (V.) lainsoni, L. (V.) braziliensis e L. (L.) amazonensis. O exame microsc��pico de bi��psias seq����nciais, obtidas dos animais a intervalos definidos de tempo (a primeira, ��s 48 ou 72 horas ap��s a inocula����o, e as seguintes, a cada 30 dias), mostrou que o desenvolvimento das les��es, independentemente da esp��cie de Leishmania inoculada, passa por uma seq����ncia de etapas a n��vel tecidual - 1) infiltrado inespec��fico cr��nico; 2) n��dulo macrof��gico (com numerosos parasitas); 3) necrose das c��lulas parasitadas; 4) granuloma epiteli��ide; 5) absor����o da ��rea necrosada (��s vezes formando granuloma de corpo estranho); 6) infiltrado inespec��fico cr��nico residual); e 7) cicatriza����o - que representaria a forma����o e a resolu����o das les��es. Discutiram-se tamb��m os prov��veis mecanismos imunopatol��gicos que determinam esta seq����ncia de eventos e sua poss��vel semelhan��a com a evolu����o das les��es na leishmaniose tegumentar humana.

Solvent-free microwave-assisted peroxidative oxidation of alcohols catalyzed by Iron(III)-TEMPO catalytic systems

The iron(III) complexes [H(EtOH)][FeCl2(L)(2)] (1), [H(2)bipy](1/2)[FeCl2(L)(2)].DMF (2) and [FeCl2(L)(2,2'-bipy)] (3) (L = 3-amino-2-pyrazinecarboxylate; H(2)bipy = doubly protonated 4,4'-bipyridine; 2,2'-bipy = 2,2'-bipyridine, DMF = dimethylformamide) have been synthesized and fully characterized by IR, elemental and single-crystal X-ray diffraction analyses, as well as by electrochemical methods. Complexes 1 and 2 have similar mononuclear structures containing different guest molecules (protonated ethanol for 1 and doubly protonated 4,4'-bipyridine for 2) in their lattices, whereas the complex 3 has one 3-amino-2-pyrazinecarboxylate and a 2,2'-bipyridine ligand. They show a high catalytic activity for the low power (10 W) solvent-free microwave assisted peroxidative oxidation of 1-phenylethanol, leading, in the presence of TEMPO, to quantitative yields of acetophenone [TOFs up to 8.1 x 10(3) h(-1), (3)] after 1 h. Moreover, the catalysts are of easy recovery and reused, at least for four consecutive cycles, maintaining 83 % of the initial activity and concomitant rather high selectivity. 3-Amino-2-pyrazinecarboxylic acid is used to synthesize three new iron(III) complexes which act as heterogeneous catalysts for the solvent-free microwave-assisted peroxidative oxidation of 1-phenylethanol.

Atlas des fossiles caract��ristiques du Lias portugais* III a) Dom��rien (Ammonites)

This fascicle, dedicated to the Domerian (Late Pliensbachian) ammonites faunas, is the third part of the ���Atlas des fossiles caract��ristiques du Lias portugais���. It follows two previous publications about the Hettangian-Sinemurian and the Carixian (Lower fifty species are concisely described and illustrated. The other groups (nautilids, belemnites, brachiopods, bivalvia...) will be published afterwards. The principal objective of the ���Atlas des fossiles caract��ristiques du Lias portugais��� is to make the main liassic lusitanian fossils known to a wide public. It also aims to support field studies by giving a rich iconography dedicated to the lusitanian invertebrate macrofaunas. In the case of the ammonites, all the species are described and the ���Atlas��� can be used as an exhaustive database for biostratigraphic and paleobiogeographic studies.

The impact of the implementation of the Basel III recommendations on the capital of portuguese banks

This paper analyses the impact of the implementation of the Basel III recommendations, using the standard method, in Portugal. For our study, we used the annual reports of 31st of December of 2012, and found out that out of the fourteen banks that published annual reports, only six satisfied the minimum ratios laid out by BCBS. Till 2012, Portuguese banks used an internal ratings method based on the Basel II recommendations known as notice 6/2010 of the Portuguese central bank, Banco de Portugal. As the implementation of the recommendations of Basel III in the EU via the Credit Review Directive IV is scheduled for 2014 and later years, Portuguese banks may severely contract credit upon implementation, as that is the easiest, fastest and cheapest way for banks to satisfy the minimum ratio requirements as compared to an increase of capital or credit spreads.
