“…and, in this case, flat wafers and wafers with trenches were also used. An important care was taken during the introduction of hydrogen and oxygen gases into the process furnace to avoid explosion hazards by setting the H2/O2 weight ratio less than 2 [21]. After oxidation, the wafers underwent to the following steps:…”

This work analyzes the influence of some chemical steps used in standard cleaning recipes on the surface micro-roughness of silicon wafers. The effect of varying the ammonium hydroxide concentration in the NH4OH: H2O2:H2O solution was studied and silicon wafer micro-roughness was characterized by atomic force microscopy technique at different scans of 1µmx1µm. Based on the results, it was possible to point the condition to obtain low surface micro-roughness for NH4OH-based solutions with the lowest NH4OH content before the growth of gate oxides. Following, it silicon-oxide thin films were grown onto periodic rectangular shapes, 100 nm in height, obtained by localized plasma etching on silicon wafer surfaces. Silicon oxides (SiO2), about 4.5 nm thick, were grown in ultrapure dry-O2 or pyrogenic (O2 + H2) environments in order to compare the planar uniformity and the grade of coverage at the step edges of rectangular shapes defined onto silicon surfaces. Pyrogenic and conventional oxidation at 850 oC allowed one to obtain gate oxides on 100 nm-stepped silicon surfaces with high dielectric breakdown field (>10 MV/cm), good planar uniformity and conformal coverage at the step edges. The impact of this result is now the feasibility of fabricating good-quality gate oxides for surrounding gate transistors (SGT’s) and texturized MOS solar cells.

“…Em trabalho anterior apontamos (Nogueira, 2002) que a fronteira poderia ser compreendida a partir de outras referências que não as clássicas tipologias de quentes/frias, vivas/mortas, naturais/humanas, políticas/econômicas, interna/externa, dentre outras, todas pautadas por uma objetividade. Procuramos compreender a fronteira tomando por base referenciais subjetivos e trabalhamos com conceitos de fronteira percebida e fronteira vivida.…”

ResumoA tradição indica pelo menos duas concepções para o conceito de fronteira: o primeiro, fundado na política, diz respeito ao limite territorial de um estado-nacional; o segundo, com um significado mais acadêmico, por isso mesmo mais restrito, fundado na economia, procura identificar processos de expansão territorial interna com a incorporação de áreas à atividade produtiva. Ambas, contudo, sempre tiveram como referência espacial uma centralidade dada seja pelo lugar do centro político, ou do centro econômico, colocando a fronteira numa condição de periferia. A proposta deste trabalho é apresentar uma discussão sobre a fronteira que a coloque numa posição de centralidade, ou seja, enquanto região que apresenta uma identidade territorial para os seus habitantes, que tome por referência os aspectos deste lugar, que apresenta singularidades frente aos territórios nacionais dos quais fazem parte. Mais do que dados objetivos (gênese, extensão), apontar-se-á referências empíricas que constituem elementos subjetivos e participam da vida cotidiana fronteiriça no Brasil com a Colômbia e da República Dominicana com o Haiti. Palavras-chaves: Fronteira, Identidade e Cultura.

“…Todos os povos antigos, como os persas, egípcios, judeus, indianos, chineses e outros, tinham conhecimento e usavam as plantas para cura das doenças (NOGUEIRA, 1983;NEVES, 1982;BIOCCHINI, 1987;LANDMAM, 1989).…”

“…O estudo das sociedades primitivas revela-nos diversos exemplos de plantas que foram usadas para doenças no passado e, modernamente, voltaram a ser utilizadas como: ginseng como afrodisíaco, efedra na oftalmologia, alho nas enfermidades relacionadas com arteriosclerose e camomila, arnica e calêndula que têm mostrado eficácia em dermatologia (BOUISSON, 1973;GOMES, 1974;BANNERMAM, 1974;CHUNG, 1978;MATOS et ai, 1991;NOGUEIRA, 1983;LANDMAN, 1989).…”

The use of a popular Fitotherapy was studied among 782 families m the district o f Campina Grande in the state o f Paraíba The study was of a "descriptive survey" kind and the technique used was an interview applied on home visits. A data assessment instrument containing open and closed questions was used as an instrument o f data collection. lt was revealed that 82,9% of the studied families had a "specialist" in "medicinal plants" who used to prepare different kinds of medicines. lt was also observed that most of them were females (93,7%) aging from 15 to 44 (47,3%), 85,0% were catholics and the majority had learned to use the plants with their own families. The medicinal plants used the most were: Lippia alba (443), Cymbopogon citratus (3 34), Sambucus australis (313), Chenopodium ambrosíoides (231), Punica granatum (231), and Peumus boldus (215), Ruta graveolens (198) and Mentha x villosa (181)The main health problems treated by "the specialists" using the plants were, gastro-intestinal (21, 1%), throat, no se and lungs (18,2%), fever and cold (13,3%), psychoneurologicals (8,3%), cardiacs and circulatories (6,5%), female genitais (6,4%) and buccal (4,3%) problems. It was shown that those medicines were usually prepared as a tea (infusion or deccoto) (63,4%) made from fresh leaves (55,0%) for the "specialists",himself, and family use in general. lt was also observed that prescription complied with those of scientifical literature indicated and that most plants were taken from the backyards of the v "specialisfs house" or the neighborhood (54,5%). A great number of specialists (57,0%) noted that they had not found any toxical plant in those places. The author showed the importance of the use of Fitotherapy to be used not only the public health services but also the need of the University to participate in the process as well as the community services teaching and cooperating with research activities.
