Abstract: Few studies have registered signs of mutilation on cetaceans in Brazil, especially from shark attacks. This work describes interactions between cookiecutter sharks Isistius spp. and cetaceans through the analysis of bite records for cetacean carcasses washed ashore on the Bahia coast between 1996 and 2005. Twenty bite records were analyzed in 13 cetacean species, of which the Delphinidae family was the most frequent. After the analysis, Isistius plutodus was identified as the aggressor species on 80% of the records, followed by I. brasiliensis (20%), based on the characteristic shape of the mutilations. The areas most subject to attack in cetaceans were: flanks 40%; head and abdomen 20% each; dorsal 15%; and genital with 5%. The relatively high number of bites on the flanks was probably due to its larger area, which offered greater opportunities to the cookiecutter shark. At least three bite records were related to the possible causes of strandings in delphinids. We recommend further studies on interactions between sharks and cetaceans along the Brazilian coast.

Abstract: Foi realizado clampeamento do pedículo hepático de rato por diferentes tempos e estudadas as repercuss es nos intestinos. Para tanto foram utilizados 40 ratos, machos, divididos em quatro grupos de 10 animais cada. O grupo S (Sham) n o foi submetido a isquemia, já os grupos E1, E2 e E3 sofreram isquemia de 10, 20 e 30 minutos respectivamente. Nossos resultados mostraram altera es macroscópicas quanto a cor dos intestinos nos grupos E2 (20') e E3 (30') e histopatológicas que ocorreram em cada um desses grupos. Observou-se que quanto maior o tempo de clampeamento do pedículo hepático, maior a congest o esplancnica, sendo que aos 30 minutos ocorreu o despreendimento do revestimento epitelial das vilosidades intestinais e hemorragia.

Abstract: the growth of violence in brazil has been producing an increasingly significant number of victims, including fatal victims. this has worried authorities and professionals, mainly those in the health area. in recent years, researchers have been searching for the diagnosis of the question and for the understanding of its risk factors in specific groups. in the city of campo grande, state of mato grosso do sul, the inexistence of information led to the conduction of a research study that aimed to outline the evolution of mortality caused by violent actions, in the period 2000-2005. we utilized data from the "sistema de informa??o de mortalidade" (mortality information system), which were made available by the health department of the state of mato grosso do sul, using icd-10 categories referring to assault, excluding intentional self-harm. the results show the magnitude of the problem in campo grande, since it affects all age groups, with greater impact on the young male population. assault by handgun discharge, by sharp object and by blunt object and assault by bodily force are the most frequent. the identification of the factors that trigger this type of violence is urgent, considering the different groups, so that it is possible to act in a preventive and efficient way.

Abstract: the use and abuse of drugs are growing problems that occur quite often in modern society. the users of legal or illegal drugs, especially when young, are found both in the suburbs and in privileged districts, in private schools as often as in the public school network. and when comparing the use of drugs by men and women, figures are almost the same. notwithstanding the multiplicity of factors composing such phenomenon, in the present research, the analysis refers to the images and discourses conveyed by the great media, especially television, and their impacts on the youth’s leisure experience. the methodology used in the analysis of eighteen beer propaganda campaigns is that of martine joly’s semiotics. we conclude that the contents of the analyzed propaganda pieces emphasize only the “beneficial” part of the drinking of alcoholic beverages in leisure experiences.

Abstract: The growing number of users of mobile communications networks and the scarcity of the electromagnetic spectrum make the use of diversity techniques and detection/decoding efficient, such as the use of multiple antennas at the transmitter and/or receiver, multiuser detection (MuD – Multiuser Detection), among others, have an increasingly prominent role in the telecommunications landscape. This paper presents a design methodology based on digital signal processors (DSP – Digital Signal Processor) with a view to the implementation of multiuser heuristics detectors in systems DS/CDMA (Direct Sequence Code Division Multiple Access). Heuristics detection techniques result in near-optimal performance in order to approach the performance of maximum-likelihood (ML). In this work, was employed the DSP development platform called the C6713 DSK, which is based in Texas TMS320C6713 processor. The heuristics techniques proposed are based on well established algorithms in the literature. The efficiency of the algorithms implemented in DSP has been evaluated numerically by computing the measure of bit error rate (BER). Finally, the feasibility of implementation in DSP could then be verified by comparing results from multiple Monte-Carlo simulation in Matlab, with those obtained from implementation on DSP. It also demonstrates the effective increase in performance and system capacity of DS/CDMA with the use of heuristic multiuser detection techniques, implemented directly in the DSP.
