1. Calcium partition in Minas Padrão cheese and its bioaccessibility during ripening time
Abstract Nutritionally, cheese and other dairy products have been highlighted especially as a calcium source. Access to minerals is dependent on variables related to diet, lifestyle, and also the health status. This study aimed to evaluate the bioaccessibility and calcium partition in Minas Padrão cheese over its ripening period for experimentally obtained

2. TOXICITY OF ALKALOID FRACTIONS FROM Psychotria spp. (RUBIACEAE) AGAINST Atta sexdens FOREL, 1908 (HYMENOPTERA: FORMICIDAE)
ABSTRACT Leaf-cutting ants are the main pests in forest plantations. The most commonly used chemical control for the ants is toxic bait. However, the active ingredients in these baits have been restricted by forest certification organizations, justifying the search for new active compounds to control these insects. Thus, this work aimed to evaluate the formi

3. O ‘grupo de Laerte’ e a escrita da história da educação (1962-1972)
Resumo: O artigo trata de uma experiência de pesquisa e escrita de história e filosofia da educação, que nos anos 1960 e 1970 tomou lugar na Universidade de São Paulo e nos Institutos Isolados de Ensino Superior, sob a orientação de Laerte Ramos de Carvalho. Esta experiência, que criou uma discernível tradição no campo de estudos historiográfico

5. A direct technique for the homogenization of periodic beam-like structures by transfer matrix eigen-analysis
Abstract To homogenize lattice beam-like structures, a direct approach based on the matrix eigen- and principal vectors of the state transfer matrix is proposed and discussed. The Timoshenko couple-stress beam is the equivalent continuum medium adopted in the homogenization process. The girders unit cell transmits two kinds of bending moments: the first is g

6. Environmental stratification in cotton in the presence or absence of genotypes with high ecovalence
Abstract Cottonseed yield data of 17 genotypes, of which two genotypes contributed to more than 30% of the total ecovalence, and grown in 23 locations, were used to compare four methods of disjoint environmental stratification: a) environmental index (Ie): favorable or unfavorable environments; b) stratification in partitions that maximize the sum of squares

7. Reflection and Refraction of Waves at the Boundary of a Non-Viscous Porous Solid Saturated with Single Fluid and a Porous Solid Saturated with Two Immiscible Fluids
Abstract The phenomenon of reflection and refraction is studied at the welded interface between two different porous solids. One is saturated with single non-viscous fluid and other is saturated with two immiscible viscous fluids. The incidence of Pf, Ps or SV wave through porous solid saturated with non-viscous fluid results in the three reflected waves and

9. Reflection/refraction at the interface of an elastic solid and a partially saturated porous solid containing liquid filled bound pores and a connected pore space saturated by two-phase fluid
Abstract The phenomena of reflection and refraction of plane waves incident obliquely at a plane interface between uniform elastic solid half-space and porous solid containing liquid filled bound pores and two-phase fluid in connected pores has been analyzed. The amplitude ratios of the reflected and refracted waves to that of the incident wave are calculate

10. Comparative Analysis of Ck- and C0-GFEM Applied to Two-dimensional Problems of Confined Plasticity
AbstractFor many practical applications in engineering, a complex structure shows linear elastic behavior over almost all its extension, but exhibits confined plasticity contained in some small critical regions, e.g. stress concentrations in fillets and sharp internal corners. The behavior of C0- and Ck-GFEM is investigated in this class of problems. The fir

11. Physical and mechanical properties of particleboard bamboo waste bonded with urea formaldehyde and castor oil based adhesive
This study evaluated the physical and mechanical characteristics of particleboards made of bamboo waste from the species Dendrocalamus giganteus bonded with two different types of adhesives: urea-formaldehyde (UF) and a castor oil based adhesive (M). Thus, eight types of particleboards were produced in the proportions of 6%, 8%, 10% and 12% for each adhesiv

12. Estudo químico, análise do óleo essencial e avaliação das atividades antioxidante e antibacteriana do Marmelhinho [Cordiera sessilis (Vell.) Kuntze (Rubiaceae)]
In this work was carried out chemical analysis, identification of volatile components, the determination of antioxidant activity and antibacterial activity of wood, bark and leaves of Cordiera sessilis (Vell) Kuntze, known as marmelinho. This study is justified because the analysis of chemical species Cordiera sessilis (Vell) Kuntze had not been studied so f
