1. Produção de vídeos caseiros pelos próprios alunos como estratégia para melhorar a aprendizagem dos conceitos abordados nas aulas regulares de Física no Ensino Médio e com ênfase no registro das atividades propostas
This work presents the results of a study about the efficience of home video productions by own students to get a better learning in Physics by the understanding of some important teachers assignments at Senior High School. The students were taught to elaborate the scripts, making off and other basic filming techniques, but the most important thing was to en

2. Uma análise empírica do consumo de música na Universidade de São Paulo / An empirical analysis of music consumption at University of São Paulo
O compartilhamento de músicas pela Internet pode ter efeitos negativos ou positivos sobre a indústria musical. Por um lado, pode limitar a poder de incentivos à criação garantidos por direitos autorais. Por outro lado, contribui para a divulgação de artistas e músicas. Este artigo estima os efeitos de downloads de música sobre o consumo de CDs e sho

3. Kohs Block Test psychometric parameters in neuropsychological assessment of executive functions / Parâmetros psicométricos dos cubos de Kohs na avaliação neuropsicológica das funções executivas
The purpose of this research was to analyze the psychometric parameters of Kohs Block Test for children and adolescents from Curitiba, to establish norms for this population and to assess the executive function connected to the prefrontal areas of the brain. Thereby, an adaptation of the administration and scoring test systems were developed, and were obtain

4. Stimulus equivalence with combined procedures and phonological consciousness in generalized reading acquisition / Equivalência de estímulos com procedimento combinados e consciência fonológica na aquisição da leitura generalizada
Equivalence class formation among pictures and spoken and printed words promotes reading with comprehension, but it does not establish the discriminative control by all the units of the word (letters and syllables). The application of combined special procedures (copy, dictation and oralization - fluently and spelled) while the teaching the conditional relat

5. The right hand copy of the nopaline Ti-plasmid 25 bp repeat is required for tumour formation.
At either end of the nopaline Ti-plasmid T-region resides a copy of a 25 bp repeated element. The normal T-DNA endpoint is 1 bp internal of the right copy, with the transcription initiation site of the nopaline synthase (nos) gene being approximately 300 bp away in the same direction. Here we describe results which demonstrate that deletion of any combinatio

6. Precise sequence complementarity between yeast chromosome ends and two classes of just-subtelomeric sequences
The terminal regions (last 20 kb) of Saccharomyces cerevisiae chromosomes universally contain blocks of precise sequence similarity to other chromosome terminal regions. The left and right terminal regions are distinct in the sense that the sequence similarities between them are reverse complements. Direct sequence similarity occurs between the left ter

7. Role of Nine Repeating Sequences of the Mini-F Genome for Expression of F-Specific Incompatibility Phenotype and Copy Number Control
An autonomously replicating 2,248-base-pair DNA segment of the mini-F plasmid carries nine 19-base-pair repeating sequences. Five of the repeats are arranged in one direction and form the right cluster, whereas the remaining four repeats are arranged in the opposite direction and form the left cluster (Murotsu et al., Gene 15:257-271, 1981). Each cluster, cl

8. The dissociation of visuospatial neglect and neglect dyslexia.
A right-handed man with a left hemisphere lesion extending into the right hemisphere, with evidence of both a left-sided neglect dyslexia and right-sided visuospatial neglect is reported. When copying simple geometric designs he omitted to copy figures on the right-hand side of the page, when bisecting lines he tended to bisect the line to the left of the li

9. Analysis of Junction Sequences Resulting from Integration at Nonhomologous Loci in Neurospora Crassa
We have analyzed the junctions involved in two examples of ectopic integration of plasmids containing the am(+) (glutamate dehydrogenase) gene into a strain of Neurospora crassa bearing a complete deletion of the am locus. In one transformed strain a single copy of plasmid DNA had been integrated into linkage group (LG) III DNA without the loss of chromosoma

10. Map Positions of Yeast Genes SIR1, SIR3 and SIR4
The HML and HMR loci in the yeast Saccharomyces cerevisiae each contain a complete copy of mating-type information. HML and HMR normally are transcriptionally inactive due to four unlinked genes, known as MAR or SIR or CMT. The map position of MAR1 (SIR2) has been reported previously; it is located on the left arm of chromosome IV, 27 cM from the centromere

11. Analyses of single-copy Arabidopsis T-DNA-transformed lines show that the presence of vector backbone sequences, short inverted repeats and DNA methylation is not sufficient or necessary for the induction of transgene silencing
In genetically transformed plants, transgene silencing has been correlated with multiple and complex insertions of foreign DNA, e.g. T-DNA and vector backbone sequences. Occasionally, single-copy transgenes also suffer transgene silencing. We have compared integration patterns and T-DNA/plant DNA junctions in a collection of 37 single-copy T-DNA-transformed

12. Ty4, a novel low-copy number element in Saccharomyces cerevisiae: one copy is located in a cluster of Ty elements and tRNA genes.
We have identified a composite element, Ty4, in S. cerevisiae that is ca 6.3 kb in length and contains two tau sequences as long terminal repeats. According to hybridization analyses, Ty4 occurs in low but varying copy number (one to four copies) in different yeast strains. By several criteria, Ty4 is a novel type of retroelement which is similar but not rel
