Avaliação de qualidade de amidos de mandioca modificados utilizados na fabricação de pão de queijo

The food industry looks for new ways and strategies to standardize the marketing products in the customer market. The modification of the cornflour that are produced in the manufacturing of the cheese bread has been one of the these ways, since some raw materials that are used to make the cornflour present different features in each supplyed allotment. The present research had as a main purpose to analyse such features looking forward to improving the quality of the final product. Thus, some tests were done to verify the pH, humidity and acidity; it was checked the percentage of carbonyl and carboxylic groups and the power of expansion to five different allotments and to farina, for example: pre-gel, natural, expandex farina as the combination of the three cited kinds. After diversifying the allotments, different results were acquired, even to an unique kind of farina and it was not possible to correlate the results of acidity, the percentage of carbonyl and carboxylic groups and the power of expansion. The pH and humidity are proper for each kind of farina. This way, the raw materials that are used for each cheese bread manufacturing must be analysed in each allotment

Intertextualidade entre Coraline e Alice's adventures in wonderland & Throught the looking-glass and what Alice found there

When writing Coraline, Neil Gaiman takes up some resources used by Lewis Carroll in his two major works, Alice's Adventures in Wonderland and Through the Looking-Glass and What Alice Found There, but still manages to write a unique novel, seemingly grim, filled with horror. In the 1960s, the theoretician Julia Kristeva conducted a study on the possible dialogue between the texts, concluding that every text contains parts of other texts, already written or that will be. Based on the theory of intertextuality she first proposed and which was subsequently discussed by several theoreticians, this paper aims to find points in the works in which this dialogue is present, as well as how Neil Gaiman appropriates these resources properly. It also tries to show elements where these points of intertextuality differ, proposing that this difference is because Gaiman resorted, directly, or indirectly, to insights drawn from the study of Freud’s psychoanalytic theory

Avaliação de gastrocitoproteção, mecanismo de ação e comparação do efeito da vitamina E (α-Tocoferol) nas formas natural e sintética

The aim of this study was to verify if α-tocopherol, the main substance of Vitamin E and also the one with the major antioxidant propriety, could offer citoprotection to a stomach damaged by alcohol. There are many forms of α-tocopherol, two forms of them were evaluated; d-l-α-tocopherol, the synthetic form and d-α-tocopherol, the natural form of α-tocopherol. Three experiments were made, all of them having absolute ethanol as the lesion agent, but the period and the doses changed in each of them. In the first two experiments, each group of animals received a different form of α-tocopherol and in the third experiment, they’ve received α-tocopherol p.o. for the period of seven days before the lesion agent was administrated. Moreover, immunohistochemistry assays were made from the stomachs samples of the third experiment to verify possible mechanisms involving nitric oxide and 2-cyclooxygenase. Satisfactory results of citoprotection have been obtained when the two forms were administered in the period of one week at doses of 100 mg/kg for synthetic form and 150 mg/kg for natural type. Nevertheless, the two forms didn’t differ statistically in their effectiveness against ethanol. The immunohistochemistry assays showed an increase of the levels of NO and COX2 in relation with the negative control, although there was no correlation between this increase and the gastroprotective effect. In conclusion, α-tocopherol has gastroprotection effect in some doses, but apparently there is no such a thing like the better the dose, the better the effect; that citoprotection don’t have a relationship with NO neither with COX2; the natural and the synthetic form don’t differ in their gastroprotection effect. More studies must be done looking forward an effective dose and also to understand the mechanisms underlay the citoprotection of α-tocopherol in the stomach

Educandas do PEJA em conversas sobre a língua inglesa e sua influência no cotidiano

This paper was developed through literacy events (Barton, 2000) about English language, understood as a social practice of writing and reading. The subjects involved in this research were women, between forty and seventy years old, students of a Young and Adult Education Project (PEJA) that occurs at UNESP/Rio Claro, whose are looking forward to conclude basic school. We intended to see in their speeches reflections about the English language presence in our society and how they deal with this foreign language. Thus, we optimize this contact exposing those women to daily situations where English language was present. To foment dialog and ideas discussions, we brought to the classes common elements, materials such as street advertisements photos with words in English. We noticed that most students recognize the constant English presence and, even they never had formal English education, they were able to establish relations between the uses of English words in everyday Portuguese at most different spheres of life. And, at many times, foreign word comprehension is related to English words use instead of a native one leading to an English naturalization process in the Brazilians speeches world.

Avaliação de sistemas de pultrudados com diferentes tipos de matrizes para aplicação em cabos condutores

In the last decades it has been observed a substantial developing of the electrical energy demand in the societies all over the World. In consequence the electrical energy distribution companies are increasing the quantity of electrical energy through the electrical energy conductor cables, which had grown the sag in the towers of energy transmission. Furthermore, the construction of more transmission towers brings a lot of troubles due environmental protection laws. In this way, looking forward to increase the quantity of electrical energy transmitted through electrical cables conductors, reduce the need of constructing new transmission towers and the sag in them, we suggest in this work the replace of the traditional core of the conductors cables commonly used, made of steel, by a core made by a composite material, which one is made by carbon fibers pultruded with polymeric resins as matrix. In a order to evaluate if the resins more commonly used in structural composites can be applied as matrix to make possible to use the composite material as a core, we made carbon fibers systems pultruded with epoxy, phenolic and polyester resins as matrix and a mechanic and physic-chemistry characterization was done on the systems by Tensile and Poisson tests, differential sprobe calorimetry (DSC), thermogravimetric analysis (TGA) and Fourier transformed infrared spectroscopy (FTIR), following their correspondents standards

Forward J/ψ production at the Fermilab Tevatron

The DØ Collaboration has recently reported the measurement of J/ψ production at low angles. We show here that the inclusion of color octet contributions in the framework of the soft color model is able to reproduce this data just as well as nonrelativistic QCD. ©1999 The American Physical Society.

Influence of a dynamical gluon mass in the pp and (p)over-bar-p forward scattering

We compute the tree level cross section for gluon-gluon elastic scattering taking into account a dynamical gluon mass, and show that this mass scale is a natural regulator for this subprocess cross section. Using an eikonal approach in order to examine the relationship between this gluon-gluon scattering and the elastic pp and (p) over barp channels, we found that the dynamical gluon mass is of the same order of magnitude as the ad hoc infrared mass scale m(0) underlying eikonalized QCD-inspired models. We argue that this correspondence is not an accidental result, and that this dynamical scale indeed represents the onset of nonperturbative contributions to the elastic hadron-hadron scattering. We apply the eikonal model with a dynamical infrared mass scale to obtain predictions for sigma(tot)(pp,(p) over barp), rho(pp,(p) over barp), slope B-pp,B-(p) over barp, and differential elastic scattering cross section d sigma((p) over barp)/dt at Tevatron and CERN-LHC energies.
