A method is presented for the determination of interface topography of multi-layered crustal models from gravity or magnetic data. The technique is developed within the framework of discrete linear inverse theory and exploits the quasi-linearity of the problem to derive…

Four studies were conducted in which three sets of tasks were devised which tapped in a standard format, progressively refined, nonlinguistic versus linguistic processes in speech processing. The third set of tasks gave the clearest results. In it, male and…

Abstract. This paper presents a method to measure the lesions originated by the Cercospora arachidicola and Cercosporidium personatum fungi, which cause, respectively, the early and late leaf spots in peanut plants. The proposed method is based on a modified version…

Abstract. This paper presents a new method based on digital image processing techniques such as color transformations and mathematical morphology, as well as on some specialist knowledge, to provide estimates for the lengths of rice panicles that have been removed…

Despite decades of research on marine algae, there are still significant gaps in basic knowledge about chemical com-position of these organisms, especially in tropical environments. In this study, the amino acid composition and contents of total nitrogen, phosphorus, lipid, carbohydrate…
