Abstract In this paper we discuss the effect of chemical reaction and thermal radiation on unsteady free convective heat and mass transfer flow through a porous medium in a vertical wavy channel. The unsteadiness in the flow is due to the oscillatory flux in the flow region. The coupled equations governing the flow, heat and mass transfer have been solved by using a perturbation technique with the slope  of the wavy wall as the perturbation parameter. The expression for the velocity, the temperature, the concentration, the rate of heat and mass transfer are derived and More >

Abstract The involucral bracts (IB or phyllaries) of the sunflower (Helianthus annuus L.) capitulum constitute an example of photosynthesizing organs that contribute to the photosynthesis budget during the generation of crop yield. The anatomy of IB was analyzed in two domesticated primitive sunflower genotypes, Havasupai and Hopi, in the sunflower line HA89B, in the wild Helianthus annuus ssp. annuus, in the sunflower male-fertile line R013 and in the commercial hybrid DKOP3845. Stomata and trichomes were counted on the adaxial and abaxial epidermis. In all cases, the IB showed a one-layered adaxial and abaxial epidermis, secretory ducts and parenchymatic cells… More >

Abstract Wild pepper (Capsicum annuum L. var. glabriusculum) is a valuable genetic resource for food and agriculture. The patterns of variation of 12 morphological traits of 17 populations of wild pepper collected across a latitudinal and climate gradients in northwestern Mexico were analyzed in a uniform greenhouse experiment. The morphological traits data were axamined by univariate and multivarite analysis. The relationship between phenotypic variation and latitude of population origen was tested using linear regression analysis. We found high variation within and among populations for most of the measured traits. Populations were clearly differentiated by univariate analysis of variance… More >

Abstract The aim of this study was to evaluate the effect of three organic fertilization sources on the agronomic and biochemical qualities of four genotypes of Serrano pepper. The experiment was performed at the field in Gómez Palacio, Durango (México). The capsaicinoids (CAP´s) are compounds responsible of the pungency of the peppers, and they are valuable for health and food and cosmetic food. The organic treatments applied were: solarized bovine manure (60 Mg/ha), vermicompost (10 Mg/ha) and poultry manure (5 Mg/ ha). A non-fertilized treatment was used as control. The evaluated variables were: length, diameter and… More >

Abstract The tanning i ndustry generates very large quantities of industrial wastes. The advancement of European policy and legislation protecting the environment has prompted the transformation of tannery solid waste materials into valuable co-products, useful to be recycled or employed in other industries. The objective of this work is to obtain gelatine from tannery wastes, in order to reuse it as natural microencapsulating agent in the production of active materials with functional properties. Concretely, this paper focuses on the influence of the extraction temperature on gelatine properties and its microencapsulating ability. An alternative enzymatic pre-treatment to More >

Abstract Graphene oxide was synthesized from graphite flakes using modified Hummers’ method. The interlayer spacings of graphite, graphite oxide and graphene oxide were measured using X-ray diffraction technique. The C/O atomic ratios of graphite oxide and graphene oxide were calculated from XPS measurements. The transformation of graphite to graphite oxide and finally to graphene oxide was clearly observed from the micro-Raman spectroscopy data and was confirmed from the FESEM micrographs. UV-VIS-NIR spectrophotometer was used to study the absorbance of graphene oxide and reduced graphene oxide samples. Finally, the chemically reduced graphene oxide was heat-treated in air More >

Abstract In this paper, a step approach method in the time domain is developed to calculate the radiated waves from an arbitrary obstacle pulsating with multiple frequencies. The computing scheme is based on the Boundary Integral Equation and derived in the time domain; thus, the time-harmonic Neumann boundary condition can be imposed. By the present method, the values of the initial conditions are set to zero, and the approach process is carried forward in a loop from the first time step to the last. At each time step, the radiated pressure on each element is updated. More >
