O jogo de esconde-esconde: trabalho perigoso e a??o social defensiva entre motoboys de Salvador
Paes-Machado, Eduardo;Riccio-Oliveira, Maria Angélica;
Revista Brasileira de Ciências Sociais , 2009, DOI: 10.1590/S0102-69092009000200006
Abstract: based on semi-structured interviews and direct observation, this paper discusses the stress-filled pursuit of safety by motorcycle couriers (motoboys) in salvador, brazil. a lack of capable guardianship forces these workers to take multi-faceted defensive social action against predatory crime to protect their vehicles, consignments, and personal belongings. the ecological (dis)advantages of urban spaces structure are, in turn, structured by this defensive action. restrictive socio-spatial tactics based on individual guardianship capabilities are compared and contrasted with expansive socio-spatial tactics involving the negotiation of guardianship resources with others. the conclusion is that, although restrictive and expansive tactics are complementary, the former are more effective means of reducing the ecological disadvantages affecting motoboys than the latter.

Abstract: purpose: evaluate the action of the gallium arsenide semiconductor laser in the post-operative evolution in dogs after the femoral head and neck artroplastic excision. methods: thirteen dogs bearing legg-calvé-perthes disease were divided into two groups: (i) 7 non-radiated dogs - control group; (ii) 6 dogs irradiated once a day for 5 consecutive days with the galium arsenide laser (904nm), energy density 4j/cm2 and exposition time automatically adjusted by the device. in order to evaluate the post-operative evolution it was needed to fill a report stating the degree of the pain as well as the weight bearing of the affected limb. a u non-parametric statistics test of mann-whitney was used to perform the results analysis. results: group i started the weight-bearing limb by means of an average of 12 post-operative days; group ii started it by 4 post-operative days. the u non-parametric statistics test of mann-whitney was statistically significant between groups (p=0.0012). conclusion: the approach suggests that the irradiation of the periarticular tissues using the low power galium arsenide laser provides a faster weight-bearing limb recovery in dogs after the femoral head and neck artroplastic excision.
Análise bioquímica dos líquidos fetais e citologia do fluido amniótico da fêmea de Mocó (Kerodon rupestris)
Zogno, Maria Amélia;Miglino, Maria Angélica;Oliveira, Moacir Franco;
Brazilian Journal of Veterinary Research and Animal Science , 2004, DOI: 10.1590/S1413-95962004000400002
Abstract: the aim of the present work was to study certain biochemical characteristics of fetal fluids of the female mocó (kerodon rupestris), by assesment of the following parameters present in the amniotic and allantoic fetal fluids: osmolarity, ph, calcium, phosphorous, total protein, urea, creatinina and glycose. ten genital systems of mocós were sampled (gestation = 30-45 and 65-70 days). the amniotic and allantoic sacs were punctured and the fetal fluid obtained for posterior analysis. it was observed the following concentrations (mg/ml) in the amniotic fluid: glycose= 45,87 ± 22,38; calcium = 6,31 ± 1,24; phosphorus = 1,64 ± 0,72; creatinine = 0,45 ± 0,12; urea = 34,03 ± 5,96; total protein = 31,24 ± 16,67. in the allantoic fluid the concentrations were: : glycose = 59,17 ± 10,85; calcium = 5,58 ± 0,59; phosphorous = 1,27 ± 0,73; creatine = 0,38 ± 0,38; urea = 31,49 ± 2,28; total protein = 30,70 ± 18,39. results obtained from the analisys of the composition of fetal fluids showed small oscillations between the amniotic and the allantoic fluids. their concentrations, probably, are determined by the materno-fetal metabolic activity. amniotic fluid cytology showed four cells types.
A veia ázigos direita na cutia (Dasyprocta aguti, rodentia)
OLIVEIRA, Paola Franssinetti Nunes Machado;CARVALHO, Maria Acelina Martins;SOUZA, Wilson Machado;MIGLINO, Maria Angélica;
Brazilian Journal of Veterinary Research and Animal Science , 1999, DOI: 10.1590/S1413-95961999000400002
Abstract: the behaviour of the azygos vein, its formation and topography were studied in 10 cutias (dasyprocta aguti, rodentia) adults (6 males and 4 females) captured in the state of piauí, brazil. this research intends to be a base for other investigations, particularly those with reference to zootechnical exploration of this species. the azygos venous system was injected with latex (neoprene 671), then the animals were put in watery solution of formol 10%, and dissected. in all specimens it was observed that the azygos vein always arrives in the cranial vena cava on a level with fourth intercostal space. the azygos vein receives more frequently (50%), the intercostal veins on the right side and 5 (50%) on the left one. the tributaries of the azygos vein are the phrenic veins (l00%), and the broncoesophagea vein (30%). the hemiazygos vein is in all cases on the left side and in 60% of the cases on the right side. the azygos vein communicates with the left hemiazygos vein (90%), with the right one (100%), and with the vena cava caudal and intervertebral veins, with equal frequency (30%).

Comparative description and discussion of spermiogenesis and spermatozoal ultrastructure in some species of Heptapteridae and Pseudopimelodidae (Teleostei: Siluriformes)
Quagio-Grassiotto, Irani;Spadella, Maria Angélica;Carvalho, Márcio de;Oliveira, Claudio;
Neotropical Ichthyology , 2005, DOI: 10.1590/S1679-62252005000300008
Abstract: the data obtained in the present study on spermiogenesis and spermatozoal ultrastructure of pseudopimelodidae and heptapteridae show that they share some characteristics, but greatly differ from each other. the main differences are the occurrence of type i spermiogenesis in pseudopimelodidae and type iii in heptapteridae, the presence of nuclear fossa in pseudopimelodidae and its absence in heptapteridae, the presence of long midpiece in pseudopimelodidae and short midpiece in heptapteridae, the presence of cytoplasmic canal in pseudopimelodidae and its absence in heptapteridae, the presence of many large vesicles in the midpiece of pseudopimelodidae and the presence of very long vesicles placed in the peripheral distal region in heptapteridae, and mitochondria distributed all over the midpiece in pseudopimelodidae, and very close to the nucleus in heptapteridae. heptapteridae and pimelodidae share several characteristics, such as type iii spermiogenesis, a similar chromatin condensation pattern, and the absence of nuclear fossa and flagellar lateral fins. the spermatozoa of pseudopimelodidae is more similar to those of siluridae. however, the absence of additional data on spermiogenesis and spermatozoa in siluriforms still limits a broader discussion in the order.

Ensaio: Avalia??o e Políticas Públicas em Educa??o , 2011, DOI: 10.1590/S0104-40362011000100009
Abstract: the dissatisfaction about the results of basic education performance in brazil is high, and the national assessment of education still indicates a persistent gap in the area. in response to this fact, the department of education of s?o paulo state has proposed measures to encourage its teachers financially. in addition to the performance bonuses, already in force, a system based on the promotion by merit within the teaching career was sent to the legislative assembly as a supplementary bill (plc). this article dicusses the limits of the principles and the efficiency of plc, based on the positive correlation between increase in compensation and performance improvement. it also analyzes the limits of the concept of quality education coupled with the logic of market. we present the precepts and inconsistencies of the plc, the results of international studies related to the effectiveness of policies for merit pay, and finally we make some considerations about the plc, in view of the international experience.
A intera??o sincronia/diacronia no estudo da sintaxe
FURTADO DA CUNHA, Maria Angélica;OLIVEIRA, Mariangela Rios de;VOTRE, Sebasti?o;
DELTA: Documenta??o de Estudos em Lingüística Teórica e Aplicada , 1999, DOI: 10.1590/S0102-44501999000100004
Abstract: in the more recent functionalist researches one can notice a strong tendency toward the historical investigation of linguistic facts, together with synchronic descriptions. the interaction and interdependence synchrony/ diachrony is central to the understanding of the process of grammaticalization since, besides the synchronic analysis of grammatical forms as a discourse-pragmatic phenomenon, primarily syntactic, one should also investigate the origin of these forms in discourse and the paths of change along which they proceed. studies on the trajectory and current configuration of items such as `onde' and `ir', of processes such as syntactic integration by embedding or of processes such as repetition and negation, give evidence of this interaction, which results in the panchronic approach.
