1. InteraÃÃes contingentes em ambientes virtuais de aprendizagem. / Contingent Interaction in Learning Management Systems
The purpose of this research is to develop an analytical system to understand the interactions in a LMS that promote learning (contingent interactions). The LMS are a class of software for the design, suport and management of Internet-based courses. Integrate Information and Communication Technologies in order to create an environment that enables the proces

2. Between expressions and contents: from semisymbolism to tensive categories / Entre expressões e conteúdos: do semissimbolismo às categorias tensivas
In the framework of French Semiotics, the concept of semisymbolism enabled a more systematic study of the contributions of the expression to the meaning in texts. It became possible to recognize categories on the level of manifestation of texts that would then be homologated to opposing pairs in the content. Though it meant a great theoretical gain, semisymb

3. ECONOMIC VALUATION OF RURAL QUINTAIS - THE CASE OF FARMERS IN CONNECTION WITH Cooperafis (AGRICULTURAL COOPERATIVE FAMILY Itapuranga-GO) / VALORAÇÃO ECONÔMICA DE QUINTAIS RURAIS O CASO DOS AGRICULTORES ASSOCIADOS À COOPERAFI (COOPERATIVA DE AGRICULTURA FAMILIAR DE ITAPURANGA-GO)
The valuation of family farming by Brazilian society constitutes an important tool for local development, since it uses scarce resources like land, labor force, efficiently. The rural homegardens are important production systems to complement other forms of land use, which besides providing food security for farmers, they perform functions aesthetic, recreat

4. Interação mãe-criança: manipulação de respostas positivas e co-variação de respostas aversivas e positivas / Interaction mother-child: manipulation of positive answers and co-variation of aversive answers and positive
Severa1 studies have demonstrated that parenting works as contexts for 1eaming both pro-socia1 and inadequate chi1dren s behavior. Exercising these practices demands specific abi1ities, which are absent in the parents repertoires that present difficulties in teaching, and maintaining the pro-socia1 behavior, controlling their chi1dren s behavior prob1ems.

5. Leitura na formação de professores de inglês da rede pública: a questão da reprodução de leitura no ensino de inglês / Reading in training of teachers for english in public network: the issue of reproduction of reading in the teaching of english
The main aim of this study is to investigate how some of the subjects involved in the process of the teaching of English, as a foreign language, develop and practice their critical sense in this teaching. Due to the preliminary results of this investigation, a phase known as process of rupture which consists of deconstructing and subverting interpretations c

6. Enunciação e dialogo
This study aims at investigatíng both the nature of the dialogue and its possibilitíes of occurrence. Firstly, critícisms are advanced in respect to conceptions of the dialoque which identify it with the process of enunciation, or which make the dialogue contingent upon extralinguistic circumstances. Consequently, the dialogue has been defined as a semant

7. Recombinant human tumor necrosis factor alpha promotes adherence of Staphylococcus aureus to cultured human endothelial cells.
Tumor necrosis factor (TNF), a potent inflammatory mediator secreted by monocytes during inflammation, was shown to significantly increase the adherence of Staphylococcus aureus to cultured human umbilical vein endothelial cells in vitro. The stimulatory effect of TNF was dose dependent and was bimodal with respect to time; bacterial adhesion peaked after 4

8. Social interaction shapes babbling: Testing parallels between birdsong and speech
Birdsong is considered a model of human speech development at behavioral and neural levels. Few direct tests of the proposed analogs exist, however. Here we test a mechanism of phonological development in human infants that is based on social shaping, a selective learning process first documented in songbirds. By manipulating mothers' reactions to their

9. CCAAT displacement protein/cut homolog recruits G9a histone lysine methyltransferase to repress transcription
CCAAT displacement protein/cut homolog (CDP/cut) is a highly conserved homeodomain protein that contains three cut repeat sequences. CDP/cut is a transcriptional factor for many diverse cellular and viral genes that are involved in most cellular processes, including differentiation, development, and proliferation. Here, we report that CDP/cut interacts with

10. Jafrac2 is an IAP antagonist that promotes cell death by liberating Dronc from DIAP1
Members of the Inhibitor of Apoptosis Protein (IAP) family are essential for cell survival in Drosophila and appear to neutralize the cell death machinery by binding to and ubiquitylating pro-apoptotic caspases. Cell death is triggered when ‘Reaper-like’ proteins bind to IAPs and liberate caspases from IAPs. We have identified the thioredoxin peroxidase

11. FF Domains of CA150 Bind Transcription and Splicing Factors through Multiple Weak Interactions
The human transcription factor CA150 modulates human immunodeficiency virus type 1 gene transcription and contains numerous signaling elements, including six FF domains. Repeated FF domains are present in several transcription and splicing factors and can recognize phosphoserine motifs in the C-terminal domain (CTD) of RNA polymerase II (RNAPII). Using mass

12. Positive and negative selection of T cells in T-cell receptor transgenic mice expressing a bcl-2 transgene.
To explore the role of bcl-2 in T-cell development, a bcl-2 transgene was introduced into mice expressing a T-cell receptor (TCR) transgene encoding reactivity for the mouse male antigen HY presented by the H-2Db class I antigen of the major histocompatibility complex (MHC). Normal thymic development is contingent on the ability of immature thymocytes to int
