The aim of the present study is to select superior cassava genotypes based on agro-morphological traits using three non-parametric indices and to correlate them in order to verify the degree of agreement between them. Traits such as number of branches, plant height, stem diameter, distance between internodes, height of the first branch, number of roots, root diameter, root length, shoot yield and root yield in experiments conducted in the Experimental Farm of Malanje Food Company were evaluated. Data collected were subjected to an analysis of variance and to Scott and Knott clustering test. Mean values were subjected to multiplicative indices of sum of classification and genotypeideotype distance. The morpho-agronomic traits used to assess the 40 cassava genotypes pointed out the existence of promising materials that can be used to diversify cassava cultivation in Angola. The sum of classification and genotype-ideotype distance indices allowed a more realistic ranking of cassava genotypes. The genotype-ideotype distance index did not present any correlation with the multiplicative and sum of classification indices as well. Genotypes Tio Jojo, Ngana Yuculu, Kimbanda, Vermute, Jaca Vermelha and Jaca Branca have the potential to be incorporated into cassava cultivation in Angola. |

This paper presents a study on the use of low resolution infrared images to detect ticks in cattle. Emphasis is given to the main factors that influence the quality of the captured images, as well as to the actions that can increase the amount of information conveyed by these images. In addition, a new automatic method for analyzing the images and counting the ticks is introduced. The proposed algorithm relies only on color transformations and simple mathematical morphology operations, thus being easy to implement and computationally light. Tests were carried out using a large database containing images of the neck and hind end of the animals. It was observed that the proposed algorithm is very effective in detecting ticks visible in the images, even if the contrast with the background is not high. On the other hand, due to both intrinsic and extrinsic factors, the thermographic images used in this study did not always succeed in creating enough contrast between ticks and cattle's hair coat. Although these problems can be mitigated by following some directives, currently only rough estimates for tick counts can be achieved using infrared images with low spatial resolution. |
