Form, size and volumetric expansion of Adzuki beans (Vigna angularis) during soaking

This study analyzed the variation in shape and size of Adzuki beans during soaking at different temperatures. In addition, different mathematical models were fitted to the experimental values of volumetric expansion, selecting the best one. Grains of Adzuki beans (Vigna angularis) with moisture content of approximately 0.25 (decimal d.b.) were manually harvested; they were, then, dried to 0.128 (decimal d.b.). The beans were subjected to soaking in distilled water at the temperatures 18 ± 1, 27 ± 1, 36 ± 1, and 45 ± 1 °C, in five repetitions. Recipients containing 80 mL of distilled water and 20 g of beans for each sample were used. The samples were periodically weighed in order to determine the water absorption. After that, the samples were removed from the recipients and placed on filter papers for two minutes to drain the surface water. Water absorption continued until the beans reached the saturation moisture content. It was concluded that, the form of the Adzuki beans was altered regularly, the orthogonal axes expanded differentially in the radial and axial directions, and that the linear model appropriately described the volumetric expansion of the Adzuki beans, among the series of models analyzed for the temperatures 18, 27, 36 and 45 °C.

Development of effervescent products, in powder and tablet form, supplemented with probiotics Lactobacillus acidophilus and Saccharomyces boulardii

Probiotics are living microorganisms, which when administered in adequate amounts confer health benefits on the host through a beneficial influence on the intestinal microbiota related to competition and to antagonistic and immunological effects. Thus, the objective of this study was the development of effervescent products (tablets and powder) supplemented with the probiotics Lactobacillus acidophilus and Saccharomyces boulardii, and the identification of the best formulation in terms of viability of these microorganisms. The physical properties of the tablets (compressive force applied, mean weight, hardness, and friability) were assessed, and the viability of the microorganisms in the gastrointestinal tract and their stability during storage were also determined. The results show that the microorganisms remained stable and viable during the 60-day storage period in the effervescent powder. However, the results indicated that the effect of compression force affected the viability of the microorganisms during the production of the effervescent tablets.

Putting the horse before the cart: a pragmatist analysis of knowledge

The definition of knowledge as justified true belief is the best we presently have. However, the canonical tripartite analysis of knowledge does not do justice to it due to a Platonic conception of a priori truth that puts the cart before the horse. Within a pragmatic approach, I argue that by doing away with a priori truth, namely by submitting truth to justification, and by accordingly altering the canonical analysis of knowledge, this is a fruitful definition. So fruitful indeed that it renders the Gettier counterexamples vacuous, allowing positive work in epistemology and related disciplines.

Form(s)-of-life: agamben's reading of Wittgenstein and the potential uses of a notion

Giorgio Agamben and Ludwig Wittgenstein seem to have very little in common: the former is concerned with traditional ontological issues while the latter was interested in logics and ordinary language, avoiding metaphysical issues as something we cannot speak about. However, both share a crucial notion for their philosophical projects: form of life. In this paper, I try to show that, despite their different approaches and goals, form of life is for both a crucial notion for thinking ethics and life in-common. Addressing human existence in its constitutive relation to language, this notion deconstructs traditional dichotomies like bios and zoé, the cultural and the biological, enabling both authors to think of a life which cannot be separated from its forms, recognizing the commonality of logos as the specific trait of human existence. Through an analogical reading between both theoretical frameworks, I suggest that the notion of form-of-life, elaborated by Wittgenstein to address human production of meaning, becomes the key notion in Agamben's affirmative thinking since it enables us to consider the common ontologically in its relation to Human potentialities and to foresee a new, common use of the world and ourselves.
