O artigo destaca a recuperação de uma informação já dada, com base nos recursos da repetição e da paráfrase, como uma estratégia de articulação textual no discurso oral dialogado. Examina algumas das funções coesivas mais freqüentes desses dois recursos, pelo enfoque de sua atuação na estrutura da organização tópica.

A presente invenção se refere ao uso de compostos derivados ftalimídicos e/ou sulfonamídicos com propriedades doadoras de óxido nítrico, os quais apresentam importantes atividades no aumento da expressão gênica de gama globina e atividades antiinflamatórias e analgésicas, potenciais ao tratamento de doenças hematológicas em que há a necessidade de diminuição dos níveis do fator TNF-<244> e a necessidade de uma fonte exógena de óxido nítrico. Mais particularmente, a presente invenção descreve o uso de tais derivados ftalimídicos e/ou sulfonamídicos para o tratamento de anemia falciforme. A invenção também apresenta como característica inovadora, a descrição de novos derivados ftalimídicos funcionalizados, desenhados a partir dos protótipos talidomida e hidroxiuréia e planejados racionalmente através da estratégia de hibridação molecular para o tratamento das doenças citadas. A invenção apresenta ainda um novo método de obtenção de um derivado sulfonamídico específico que pode ser utilizado na preparação de um medicamento para tratamento de doenças em que há a necessidade de diminuição dos níveis do fator TNF-<244> e a necessidade de uma fonte exógena de óxido nítrico.

Preparation and use of phthalimide and/or sulphonamide derivatives with nitric oxide donor properties, having activities in increasing gamma-globin gene expression and anti-inflammatory and analgesic activities, effective in the treatment of hematologic diseases which require reducing the TNF-[alpha] levels and an exogenous source of nitric oxide, such as sickle-cell disease. The functionalized phthalimide derivatives are designed from the prototypes thalidomide and hydroxyurea.

When a bolted joint is loaded in tension with dynamically, part of this load is absorbed by the bolt and rest is absorbed by the joint material. What determines the portion that is to absorbed by the bolt is the joint stiffness factor. This factor influences the tension which corresponds to pre-load and the safety factor for fatigue failure, thus being an important factor in the design of bolted joints. In this work, three methods of calculating the stiffness factor are compared through a spreadsheet in Excel software. The ratio of initial pre-load and the safety factor for fatigue failure depending on the stiffness factor graph is generated. The calculations for each method show results with a small difference. It is therefore recommended that each project case is analyzed, and depending on its conditions and the range of stiffness values, the more or less rigid method about the safety factor for fatigue failure is chosen. In general, the approximation method provides consistent results and can be easily calculated

This study aimed to evaluate the dynamic factor applied to the results obtained by dynamic resistance formulas Janbu and Hiley, would lead to the results obtained by static strength analysis CAPWAPC ®. The evaluation was done by backcalculation dynamic loading tests (ECD), taking into consideration the type of soil in which the cutting base precast concrete were settled, and using the information on the effective energy transmitted to the stakes by hammers, obtained by CAPWAPC ®. The results are shown in tables and graphs, and showed that the use of these formulations and their dynamic factors can become an efficient and economical field, assisting the engineer in making decisions regarding the staking of the work

The Brazilian livestock stands out for having the world largest commercial herd of cattle and leads meat exportation and production of bovine embryos. The in vitro production (IVP) of embryos is considered an effective option to overcome problems such as infertility in cows with high economic value and also for genetic improvement of cattle. The in vitro oocyte maturation is an essential step to the success of IVP, but is still considered poor when compared to in vivo maturation. Recent studies have suggeested an important role of Fibroblast Growth Factor 10 (FGF10) on the in vitro maturation of oocytes, which favored the expression of genes related to oocyte maturation and cumulus cell expansion. Aware that maturity stage influences the final production of blastocysts, we aimed study to verify if the addition of FGF10 into the maturation medium is able to affect positively the IVP of bovine embryos. Hence, FGF10 was added to maturation in five different concentrations: 0.5 ng/mL (group 0.5), 2.5 ng/mL (group 2.5), 5 ng/mL (group 5), 10 ng/mL (group 10) and 50 ng/mL (group 50). Additionally, two other maturation groups were used, group BSA (Bovine Serum Albumin, 4 mg/mL) and group FCS (Fetal Calf Serum, 10%). The rates of cleavage, morula and blastocyst were analyzed by Analysis of Variance (ANOVA), differences of P<0.05 were considered significant. Cleavage rates did not differ between the seven groups. On the other hand, morula rate on FCS group was higher than groups BSA, 0.5, 10 and 50 (P<0.05), but did not differ among groups treated with intermediate doses of FGF10 (2.5 and 5). FCS group presented higher blastocyst rate compared to all other groups that were well below the FCS group (P<0.0001). Therefore, the use of FGF10 during oocyte maturation did not affect positively embryo development on the IVP of bovine embryos
