The swine manure contributes significantly to the degradation of natural resources and to decrease the quality of life in the southern state of Santa Catarina, Brazil. The excess of manure produced by the large number of pigs per unit area hinders the solution of the problem. This study aimed to evaluate the behavior of a system developed to treat swine manure, in series and in real scale, composed of anaerobic units, aerobic units and post-treatment. The parameters analyzed were: BOD, COD, TP, PO4-P, NH3-N, TKN, pH, chlorophyll a, algal biomass, total coliforms and fecal coliforms (Escherichia coli). The system showed that, after one year of operation, the removal efficiencies were satisfactory for organic matter and nutrients, reaching values of 97% for BOD, 95% for COD, 88% for N-NH3 and 74% for PT/P-PO4, even with variations in flow and organic load applied. However the removal of fecal coliforms in the aerobic units was low, decreasing only 0.86 log units in the aerated facultative pond and 0.80 log units in the maturation pond.

Evolução e reversibilidade das lesões neurológicas e cardíacas em ovinos intoxicados experimentalmente por Ateleia glazioviana e Tetrapterys multiglandulosa

To determine the reversibility of neurological and cardiac lesions in Ateleia glazioviana and Tetrapterys multiglandulosa poisoning, 3 groups of four sheep each were fed orally with the plants. In Group 1, 2 and 3, when sheep with nervous signs showed considerable increase of symptoms and risk of death, the plant administration was suspended. Group 4 with two sheep was used as control. Sheep from Group 1, fed 10g/kg during 6 days of fresh A. glazioviana collected in autumn were euthanized 8, 11, 16, and 21 days after the start of the experiment; they had shown regression of nervous signs, but had progressive cardiac lesions. Sheep from Group 2, fed during 8 days the same dose of fresh A. glazioviana collected in spring, were euthanized on days 9, 23, 38 and 68; they had shown regression of nervous signs and had no cardiac lesions. This suggests that the plant is less toxic in spring. Sheep from Group 3, fed 10g/kg during 11 days dry and ground T. multiglandulosa mixed with concentrated food, were euthanized on days 33, 33, 92 and 92; they had shown regression of nervous signs, and cardiac lesions were less severe on day 33 than on day 92. These results indicate that nervous lesions are reversible after the end of feeding, but cardiac lesions are progressive after discontinuation of the plant administration; these can be afterwards reversible if the animals do not anymore show clinical signs or die as a consequence of the poisoning. Results of those and previous experiments show that lesions of the nervous system are induced by lower doses than cardiac lesions and occur within a shorter period, what suggests that in spontaneous cases cardiac signs are always preceded by nervous signs, and that nervous signs can occur in the absence of cardiac lesions.

A importância da inovação e seus desdobramentos sobre a pesca industrial dos estados do Pará e Santa Catarina (Brasil)
(Universidade Federal do Pará, 2013-06-28) SANTOS, José Nazareno Araújo dos; BASTOS, Ana Paula Vidal; http://lattes.cnpq.br/1992388595130579
Innovation is crucial to reach the socioeconomic development pursue by each country. Those that do not innovate or link innovation to their development agenda are left behind to the “centre”. This is so true, that developed countries are all more industrialized and innovative than those not developed. In Brazil this is also the case, despite being the sixth largest economy in the World, she is not a developed country, mainly because it occupies an intermediate position regarding manufacturing and innovation. This reflects throughout all activities including fisheries. Despite having a high productive potential extractive fishing when compared to other countries presents low production capacity, mainly due to the (un)willingness to adopt/develop innovative techniques that may enable a better performance. Another aspect that should be highlighted is its weak institutional capacity to promote sectorial development. In order to find alternatives to the current institutional structure of fisheries, Brazilian government, following institutional structures adopted by major fishing production countries, in 2003, adopted a new governance pattern for the sector. However, it did not change former structures. Therefore, remains relevant to identify those factors that make this important socioeconomic activity, hostage of market nuances and local circumstances that lead to inequality of the production assets of agents. In order to deeply understand it, this research in Brazilian states of Para (in the North/Amazon region) and Santa Catarina (in the South). Besides being the largest fishing producing states, are largely vulnerable to market behaviour and, at the same time present very unequal institutional frameworks and positions towards innovation. In order to compare the two states having in mind the role of innovation in the production process, an Innovative Performance Index was created based on multivariate analysis. Thus, primary data collected in the two states was submitted to a factor analysis. Results show that Santa Catarina's companies showed better results confirming the guiding hypothesis that innovation is the key to good performance at least in the fishing activity. Not forgetting that other context factors matter, including those institutional agents that closely follow domestic and international market dynamics. Another result that need to be highlighted refers to strategic skills of the entrepreneurs, that may perform better because can better cope with market complexity. Santa Catarina's entrepreneurs showed greater commitment to innovation reflected in the behaviour of their companies. These empirical results allow saying that a better integration of the institutions that coordinate agents involved in the fishing activity can create an environment that may promote a sound development of the activity and that this may apply to other sectors. This research deepened the discussion of the intricacies of innovation and its implications on development policy, allowing for strategic hints for those involved in regional and sectorial policy making.

Wave refraction and longshore transport patterns along the southern Santa Catarina coast
(2007-06) SIEGLE, Eduardo; ASP NETO, Nils Edvin
Based on the wave climate for the southern Brazilian coast, wave refraction has been modelled in order to obtain the refracted wave heights and directions along the southern Santa Catarina coast, providing the needed information for potential longshore drift estimates. According to its coastline orientation, different sectors of the coast present varying longshore drift patterns. Estimates have been made for the yearly-averaged wave climate as well as for each season, showing thereby the longshore drift patterns along the year. Based on the results of the potential longshore drift intensities and directions and on the shoreline outline in plan, it has been possible to identify a strongly drift-dominated coast in the south turning to a mixed drift and swash dominated coast towards the north of the studied area. Contrasting patterns of longshore drift between the southern and northern portion of the coastline indicate a sediment surplus in the central portion, making sediment available for cross-shore transport processes, either on- or offshore. Considering long-term aspects, the longshore drift patterns are in agreement with the coastal infilling process which has mainly been driven by persistent surplus from littoral sediment drift.
