Abstract: this paper is about how the several cultural patterns and prevailing customs at different times impose on children realities that are sometimes unfair. the authors consider that the family model is socially constructed based on some beliefs which then result in some situations that can be characterized as violence. finally, the authors suggest that the culture needs to be shared in harmony among the various social actors, rather than being preserved in an arbitrary way.
A violência na infancia como uma quest o cultural

Texto & Contexto - Enfermagem , 2006,
Abstract: Este artículo trata de como los diferentes patrones culturales y las costumbres que adquieren en diferentes epocas imponem a los ni os realidades ni siempre justas. Las autoras consideran que el modelo de la familia és construida socialmente, a apartir de ciertas creencias, que resultan en situaciones que pueden ser caracterizadas como violencia. Finalmente, sugieren que la cultura deve ser compartida en concordancia con los diversos actores sociales, y no preservarse de forma autoritária.

Jornal de Pediatria , 2006,
Abstract: OBJETIVO: A anemia hemolítica auto-imune é caracterizada pela produ o de auto-anticorpos contra antígenos de superfície das hemácias. O objetivo do estudo foi identificar as características clínicas, imunológicas e evolutivas dos pacientes com anemia hemolítica auto-imune acompanhados no servi o de hematologia pediátrica do HC-UFMG e no Hemocentro de Belo Horizonte. MéTODOS: Foram avaliadas 17 crian as menores de 15 anos, diagnosticadas entre 1988 e 2003. O diagnóstico de anemia hemolítica auto-imune foi baseado no quadro de hemólise adquirida e confirmado por meio do teste de Coombs direto poliespecífico. Os dados clínicos, demográficos, laboratoriais e referentes à evolu o dos pacientes foram obtidos retrospectivamente nos prontuários médicos. RESULTADOS: A mediana de idade ao diagnóstico foi de 10,5 meses. O teste de Coombs direto poliespecífico foi positivo em 13 pacientes e negativo em quatro. Em 14 pacientes, foi realizado o teste de Coombs direto monoespecífico. Nestes, a classe de anticorpo mais freqüente foi IgG (cinco pacientes), seguida pela IgM em dois. Em 13 (76%) pacientes, a anemia foi considerada grave, o que tornou necessária a hemotransfus o. Em quatro pacientes, foi identificada uma doen a de base: lúpus eritematoso sistêmico, linfoma de Hodgkin, hepatite auto-imune e histiocitose de células de Langerhans. Os demais casos foram considerados como primários. A mediana de seguimento foi de 11 meses (5 a 23 meses). Ocorreram três óbitos, sendo dois após esplenectomia e um pela doen a de base. CONCLUS O: A anemia hemolítica auto-imune é rara em crian as e adolescentes. Apesar de apresentar resposta ao corticóide e imunoglobulina, casos fatais têm sido relatados. O prognóstico é pior na presen a de uma doen a cr nica de base.

Abstract: aiming to contribute to the current and intense process of revision of conceptions and educational practices mediating learning and development of young children in day care centers and pre-schools, and based on our research experiences at cindedi, this paper approaches several questions which, in our view, are relevant for the understanding of collective education. how does developmental research contribute to this discussion? what conceptions about development is it based on? which methodological perspectives are more promising for the comprehension of the ways children and their teachers act and change with their experiences? how to understand notions such as developmental stages, teachers’ role in the learning process, factors explaining infant development and developmental evaluations in infancy? both family and childcare professionals interact with the child and organize his/her environment according to their expectations about his/her development and their own role in this process. these expectations are built through their life experiences in their particular culture. many expectations, beliefs and psychological theories have, thus, a strong self-fulfilling power, helping to build competencies and deficiencies. children and the professional staff of child education institutions have undoubtedly much to gain from reflecting on these questions.

Abstract: the determination of the blood group antigen profile of blood donors and transfusion patients is important to avoid alloimmunization. the knowledge of blood group polymorphisms acquired over the last few years has permitted the development of molecular methods that are able to predict blood group phenotypes. for patients who have recently been transfused or those who present with autoimmune hemolytic anemia, genotyping is an important tool in blood typing. we used molecular biology (allele-specific pcr and pcr-rflp) to genotype rh (rhd, rhce*c/c, rhce*e/e), kell (kel*1/kel*2), kidd (jk*a/jk*b) and duffy (fy*a/fy*b and fyb(-33t>c)) alleles and solved the inconclusive blood types of 36 patients. twenty patients had developed irregular antibodies of different red blood cell antigens, most frequently anti-e (55%). the definition of irregular antibodies was feasible by genotyping. due to their accuracy, simplicity and economic viability, these tests have been used in the clinical practice in our institution since 2007, contributing to the management of chronically transfused patients. additionally, these tests allow a better use of less common blood units related to the ethnicity of the blood donor population.
Stress tensor computation from earthquake fault-plane solutions: an application to seismic swarms at Mt. Etna volcano (Italy)

Annals of Geophysics , 1997, DOI: 10.4401/ag-3867
Abstract: Fault-plane solutions of some tens of local earthquakes which occurred at Mt. Etna volcano during 1983-1986 have been inverted for stress tensor parameters by the algorithm of Gephart and Forsyth (1984). Three seismic sequences were focused on which respectively occurred during a flank eruption (June 1983), just after the end of a subterminal eruption (October 1984) and during an inter-eruptive period (May 1986). The application to the three sets of data of both the "approximate" and the "exact" methods evidenced the stability of results, and the stress directions are well defined in spite of the small number of events used for the inversion. The s1 obtained agrees with the regional tectonic framework, nearly horizontal and oriented N-S, only in the shallow crust, and just after the 1984 eruption. This supports the hypothesis of a tectonic control on the end of the eruptive activities at Mt. Etna. Conversely, results concerning the depth range 10-30 km are in apparent disagreement with other investigations (Cocina et al., 1997), as well as with the regional tectonics. The stress was here found homogeneous, but with s1 respectively trending ENE-WSW (June 1983) and E-W (May 1986). We suggest that the stress field could be temporarily modified by a local stress regime driven by the intrusion of uprising magma.
Low frequency events at Mt. Etna: some problems and open questions
S. Alparone,S. Gresta
Annals of Geophysics , 1996, DOI: 10.4401/ag-3971
Abstract: A short period seismic array setting at Mt. Etna symmetrically in regard to the fracture of the 1991-1993 eruption allowed an analysis of low frequency events which occurred in the first phase of the mentioned eruption. We recorded about 50 events, 19 of them belong to a family. They show very low amplitude values and spectral peaks ranging 0.5-4.5 Hz. The evidence of this family of events shows how the process driving the dynamics of the fluid in the volcano is often the same.
Growth and Yield Performance of Five Guar Cultivars in a Mediterranean Environment
Orazio Sortino,Fabio Gresta
Italian Journal of Agronomy , 2008, DOI: 10.4081/ija.2007.359
Abstract: In order to evaluate growth and yield performance of guar (Cyamopsis tetragonoloba L.) in Mediterranean area, main morphological parameters (plant height, dry weight of single plant parts, branch and leaf number), dry biomass accumulation and seed yield response of five varieties of guar (Esser, Malosan, Kinman, Lewis and Santa Cruz) were studied. Seed crude protein and fibre content were also determined. Irrigation was applied to ensure that water availability did not limit production. The growing season of guar lasted for 120 days for all the varieties. Average plant height at harvest was about 63 cm (ranging from 56.0 to 70.6 cm). The highest dry weight increment was recorded during 55-70 days after sowing. Malosan, Santa Cruz and Kinman showed the highest individual seed weight (> 30 mg). Above average leaf and branch number were observed in Kinman, Esser and Santa Cruz. The greatest seed protein content was observed in Lewis and Esser (35.6% and 34.7%). High yield and seed quality were obtained in these environments with limited water supply, indicating that guar may represent a valid alternative multipurpose crop for semiarid regions.
