Separation of satured and unsaturated fatty acids from palm fatty acids distillates in continuous multistage countercurrent columns with supercritical carbon dioxide as solvent: a process design methodology

In this work the separation of multicomponent mixtures in counter-current columns with supercritical carbon dioxide has been investigated using a process design methodology. First the separation task must be defined, then phase equilibria experiments are carried out, and the data obtained are correlated with thermodynamic models or empirical functions. Mutual solubilities, Ki-values, and separation factors aij are determined. Based on this data possible operating conditions for further extraction experiments can be determined. Separation analysis using graphical methods are performed to optimize the process parameters. Hydrodynamic experiments are carried out to determine the flow capacity diagram. Extraction experiments in laboratory scale are planned and carried out in order to determine HETP values, to validate the simulation results, and to provide new materials for additional phase equilibria experiments, needed to determine the dependence of separation factors on concetration. Numerical simulation of the separation process and auxiliary systems is carried out to optimize the number of stages, solvent-to-feed ratio, product purity, yield, and energy consumption. Scale-up and cost analysis close the process design. The separation of palmitic acid and (oleic+linoleic) acids from PFAD-Palm Fatty Acids Distillates was used as a case study.

Impact of inulin and okara on Lactobacillus acidophilus La-5 and Bifidobacterium animalis Bb-12 viability in a fermented soy product and probiotic survival under in vitro simulated gastrointestinal conditions

The effect of inulin and/or okara flour on Lactobacillus acidophilus La-5 and Bifidobacterium animalis Bb-12 viability in a fermented soy product (FSP) and on probiotic survival under in vitro simulated gastrointestinal conditions were investigated throughout 28 days of storage at 4 °C. Employing a 22 design, four FSP trials were produced from soymilk fermented with ABT-4 culture (La-5, Bb-12, and Streptococcus thermophilus): FSP (control); FSP-I (with inulin, 3 g/100 mL of soymilk); FSP-O (with okara, 5 g/100 mL); FSP-IO (with inulin + okara, ratio 3:5 g/100 mL). Probiotic viabilities ranged from 8 to 9 log cfu/g during the 28 days of storage, and inulin and/or okara flour did not affect the viability of La-5 and Bb-12. Bb-12 resistance to the artificial gastrointestinal juices was higher than for La-5, since the Bb-12 and La-5 populations decreased approximately 0.6 log cfu/g and 3.8 log cfu/g, respectively, throughout storage period. Even though the protective effect of inulin and/or okara flour on probiotic microorganisms was not significant, when compared to a fresh culture, the FSP matrix improved Bb-12 survival on day 1 of storage and may be considered a good vehicle for Bb-12 and could play an important role in probiotic protection against gastrointestinal juices. © 2013 Elsevier Ltd.

O design e o produto: parâmetros projetuais para o planejamento de jogos geométricos pré-escolares

Educational games are responsible for part of the information assimilated by the child, because these games respect the individual learning time, enabling experimentation and, consequently, being an accessory to retain the acquired knowledge spontaneously. However, the analogy between stimulus and reception/result is not always the expected. On the one hand, there are the pedagogues, bearing the knowledge necessary to the children’s development. On the other hand, are the children, who cannot completely assimilate the concept, commonly because of lack of planning on the product. After all, the children become not interested in the game, without developing the expected cognitive abilities planned for the product. Whereas the importance of the games on children’s development, this work aimed to analyze and select educational games presented on the preschool, based on the language exploration from the Design’s knowledge and skills. Specifically, the research intends to investigate games targeted to stimulate geometric concepts, and so, to describe parameters that must be observed during the product planning.

Um estudo sobre o desenho aplicado ao design

Although technological development has created several tools and techniques of graphic representation, we highlight here the importance of the manual drawing abilities for the design creative process. Freehand drawing is used to facilitate the development of projects and show them more quickly and efficiently, and is an essential technique for any designer, regardless is informational, product or fashion designer.

A ornamentação contemporânea em arte e design: função estética, anagógica, terapêutica

Taking as a starting point the reflection on the ornament, is delineated an interpretative analysis of delimitation between art and design in the extent of the aesthetics. Presupposing the ornament as an elementary and universal form of the all aesthetics’ manifestations, trying to work, through recent contributions and in an unified way, concepts regarding the aesthetics in parallel with the phenomenon of the perception. The ornament as element previously “ordered” front to the organization need that the interpretation demands, it constitutes fertile philosophical instrument, for all the art forms and of design, which seeks to provide an aesthetic sensation. Returned to the thoughtful function, the ornament has as essential purpose to stimulate the aesthetic experimentation, capable to induce the perception to subtler states of conscience similar of to the ecstasy, where the spirit from whom contemplates, can live experiences of extreme freedom and intense pleasure. . Establishing semiotics foundations capable of evidencing a function anagogic-therapeutics in the action of conceiving and to meditating, alternately, an object with function strictly ornamental (aesthetics), also intending the reflection of moral stamp on the ornamental concept of the decency as conciliatory solution in the intersection between art and design, concerning the creativity of the formative process.

Procedimentos metodológicos em design gráfico voltados a jornais diários impressos: estudos e relatos de experiência

This paper summarizes a research that has been developed from the concern about a company’s strategic planning, once regarding the product development process and its methodological guidelines. Our goal was to check if there is an ideal methodology, peculiar to the graphic design, which could be applied to a printed newspaper condition. And then, we could deduce, according to the design practices in newspapers, its relevance. We did not intend to create a specific graphic design methodology for daily newspapers, nor the analysis of methods, but we wanted to emphasize that the familiarization with acknowledged methods in the field of visual communication, during the process of professional formation, might ease good choices in the work practice on design. The understanding of the gradual introduction of graphic design on printed daily newspapers brings about, thus, not only their visual improvement, but also allows that this kind of journalism (which depends on a graphic interface in order to make their product come true) reconsider the newspaper as a whole.
