Centenas de intrusões alcalino-ultrabásicas ocorrem na região sul-sudoeste de Minas Gerais. Duas destas intrusões, portadoras de diamantes e conhecidas como “Canastra-1” e “Abel Régis”, foram estudadas em detalhe visando seus aspectos geológicos, geoquímicos e mineralógicos. A segunda foi ainda objeto de datação LA-MC-ICP-MS em zircão. Em termos geológicos, tais intrusões exibem diferenças morfológicas significantes: a forma superficial do Canastra-1 é irregular e de pequena dimensão (150 m de comprimento maior), enquanto o Abel Régis é circular e de grande diâmetro (~1,4 km), as quais representam, respectivamente, fácies de raiz e de cratera. A geoquímica dessas intrusões apresentou características peculiares, principalmente quanto aos álcalis: o pipe Canastra-1 é empobrecido em Na2O e K2O, óxidos que possuem conteúdos significantes no pipe Abel Régis, este datado em 86,1 ±4,5Ma. Os aspectos mineralógicos das fases indicadoras de diamantes também são bastante distintos: a abundância em Cr-espinélio, bem como a presença de sanidina e a química mineral de ilmenita e diopsídio, são indicadores de uma possível “tendência” lamproítica para o pipe Abel Régis, enquanto o Canastra-1 possui aspectos geoquímicos e mineralógicos de um kimberlito clássico.

Estas notas reproduzem comunicação apresentada na IV Semana Universitária do Instituto de Letras, Ciências Sociais e Educação da Universidade Estadual Paulista (ILCSE-UNESP — Campus de Araraquara), em outubro de 1980. Elas consistem na formulação de algumas hipóteses de investigação calcadas no exame preliminar de dois tipos de fontes: a) entre as fontes primárias, manifestos, documentos e depoimentos dos movimentos sindicais espanhol (1960-78) e brasileiro (1970-1980); b) entre as fontes secundárias, a literatura existente sobre a história do sindicalismo urbano, na Espanha e no Brasil, referente, sobretudo, ao período acima citado.

PURPOSE: to quantify and to compare the typology of disfluencies in the speech of adults who clutter and adults with developmental persistent stuttering. METHOD: participants of this investigation were 15 adults, divided in two groups: Group of Adults Who Clutter, composed by 5 individuals and Group of Adults Who Stutter, composed by 10 subjects. The procedures used were: Assessment of Fluency, Predictive Cluttering Inventory and Stuttering Severity Instrument. RESULTS: the data indicated that the groups differed regarding the occurrence of other disfluencies (p=0,021) and stuttering-like disfluencies (p<0,001). The analysis for the types of other disfluencies revealed that there was statistically significant difference for the interjections, revision and unfinished word. The Group of Adults Who Stutter showed statistically significant increase of all the types of stuttering-like disfluencies. CONCLUSION: the group of adults who clutter showed increase of the occurrence of the other disfluencies, whereas the group of adults who stutter showed increase in the occurrence of the stuttering-like disfluencies. The other disfluencies were variable in both groups and those who clutter show less types of stuttering-like disfluencies when compared to those who stutter.

PURPOSE: to evaluate and compare the fluency between the familial and the sporadic persistent developmental stuttering, characterizing the typology and the frequency of the disfluencies, the speech rate and the severity of the stuttering. METHOD: 40 participants aged from 6 to 42 years old, divided in two groups with twenty participants in each one: Familial Persistent Developmental Stuttering and Sporadic Persistent Developmental Stuttering. The procedures used were: clinical and familial history, assessment of fluency and Stuttering Severity Instrument. RESULTS: there were no statistically significant differences between the groups regarding the frequency of stuttering like disfluencies, the flow of syllables and words per minute and the severity of stuttering. It was noted a tendency of the group with familial stuttering to show a bigger variability of the severity of stuttering, going from mild to very severe, whereas in the group with sporadic stuttering, the severity varied from mild to severe. CONCLUSION: this study represents the first effort to the characterization of the speech fluency profile of the subgroups of people who stutter, namely familial persistent developmental stuttering and sporadic persistent developmental stuttering. It is possible to conclude that the speech fluency profile of people who stutter, independently of the familial history, is similar. It is noteworthy that the occurrence of some stuttering-like disfluencies, monosyllabic word repetition, block and intrusion were different between groups.

This paper discusses the results of an investigation of academic achievement by gender and student perception of the expectations of their teachers. 120 students from the 5th year of primary education municipal public schools in the metropolitan region of Campinas city participated in the research: 60 of the students have satisfactory academic performance and the other 60 have unsatisfactory performance. We used a scale of student perception of teacher expectations and, to measure academic performance, we considered the grade teachers assigned to students. Research results revealed significant differences between boys and girls in the group of students with unsatisfactory performance, because most of them (83.3%) were male. On the other hand, there were no statistically significant differences between boys and girls in the group with satisfactory academic performance, although girls' average academic performance was higher. Regarding the perception of their teachers, we observed differences in both groups. Students with satisfactory performance have the perception that they are more praised and more often chosen to assist the teacher in the classroom while underperforming students believe they receive more criticism from their teachers and are seen as more unruly. The data allow discussing student-teacher bond, the influence of experience at the time of learning and how it influences the interest and motivation of students.

Water loss increase through evapotranspiration is one the most important modes of interference of weeds in water bodies, especially in water storage reservoirs. Thus, this research was conducted to compare the water losses in mesocosms colonized with the aquatic weeds Myriophyllum aquaticum,Brachiaria subquadripara,Echinochloa polystachya,Typha latifolia and Pontederia lanceolata. The evaluations were carried out in July 2004, in three 4-day periods. The water losses were evaluated based on the amounts of water necessary to restore the existing water level before each evaluation period. The colonization of the aquatic weeds increased the water losses in the mesocosms, with the highest losses being observed in those colonized by T. latifolia, between 3.54 to 4.71 times the water surface without aquatic weeds. The losses in the mesocosms colonized by M. aquaticum,B. subquadripara, E. polystachya, and P. lanceolata were statistically similar and promoted increases between 1.54 to 2.21 times the free surface. The results showed that aquatic weed control is important to prevent water losses in reservoirs used for water storage.
