1. ARTIFICIAL NEURAL NETWORK-BASED METHOD TO IDENTIFY FIVE VARIETIES OF EGYPTIAN FABA BEAN ACCORDING TO SEED MORPHOLOGICAL FEATURES
ABSTRACT One of the new crop varieties that have been adopted for high yield is the Egyptian faba bean. However, poor-quality faba bean has reduced economic value. Quality evaluation is thus important and can be performed using computational intelligence. We developed a robust method based on morphological features and artificial neural network for quality g

2. Phylogenetic placement of Tritirachium strains from the URM culture collection originally founded by Augusto Chaves Batista (1916-1967) in Brazil, and the description of T. batistae sp. nov.
ABSTRACT Twenty-seven Tritirachium strains were present in the URM culture collection originally founded in Brazil by Augusto Chaves Batista. Fifteen freshly-prepared cultures were obtained from these original strains preserved under mineral oil. DNA was extracted for analysing phylogenetic relationships using the sequence information available from Tritirac

3. An Outbreak of Intestinal Obstruction by Ascaridia Galli in Broilers in Minas Gerais
ABSTRACT Industrial broilers raised on helminthic medication-free feed were diagnosed with a severe disease caused by Ascaridia galli, characterized by intestinal hemorrhage and obstruction. A. galli was identified based on the morphological features of the nematode. Broilers were raised for a longer period (63 days) for weight recovery, grouped as stunted (

4. Caracteres importantes na identificação de espécies de Ludwigia (Onagraceae) ocorrentes no Recôncavo da Bahia, Brasil
Resumo Na flora aquática do Brasil, o gênero Ludwigia apresenta ca. 48 espécies. A maioria das espécies de Ludwigia é anfíbia, apresentando uma grande plasticidade fenotípica, o que torna sua identificação complexa. O objetivo deste trabalho foi realizar um levantamento taxonômico e analisar caracteres diagnósticos na delimitação das espécies d

5. Mysidopsis gemina n. sp. (Crustacea: Mysida: Mysidae) from the northern Pacific coast of Costa Rica
Abstract Mysidopsis gemina n. sp. is described from protected and exposed beach habitats in the provinces of Puntarenas and Guanacaste on the northern Pacific coast of Costa Rica. Morphologically, M. gemina most closely resembles M. furca Bowman, 1957 known from the Atlantic and Gulf Coasts of North America. Both these species are unique within the genus by

6. Naming structures and qualifying properties of anuran bioacoustical signals: a call for a homology-based nomenclature and equality for quantitative data
Abstract: There is a significant interest for using call features in taxonomic and systematic studies. However, the indiscriminate use of alternative terms for the acoustic structures has precluded reliable comparisons among species without directly checking recordings of all compared species. Recent attempts of nomenclature standardization have focused on t

7. In vitro Evaluation of PHBV/PCL Blends for Bone Tissue Engineering
The objective of this study was to evaluate Vero cells in in vitro biocompatibility tests with pure PHBV and PCL and 75/25 and 50/50 blends developed for bone tissue bioengineering in dense or porous forms. The biomaterials were characterized morphologically by scanning electron microscopy, (SEM) stereoscopic imaging (SI), and micrometer measurement. Cellula

8. Otobone®: Three-dimensional printed Temporal Bone Biomodel for Simulation of Surgical Procedures
Abstract Introduction The anatomy of the temporal bone is complex due to the large number of structures and functions grouped in this small bone space, which do not exist in any other region in the human body. With the difficulty of obtaining anatomical parts and the increasing number of ear, nose and throat (ENT) doctors, there was a need to create altern

9. Microwave radiation influence on the thermal and spectroscopic properties of Na-birnessite-type material
Resumo No presente trabalho, apresenta-se um estudo da influência da radiação micro-ondas nas propriedades térmica e espectroscópica, assim como estrutural (ordem-desordem) e morfológica, de óxido de Mn estruturado em camada tipo Na-birnessita. A rota empregada para obtenção da matriz lamelar foi a precipitação redox. Os produtos foram caracteriza

10. Morphological description and new records of Hygrocybe conica var. conica and H. nigrescens var. brevispora (Hygrophoraceae) in Brazil
RESUMO Hygrocybe conica var. conica e H. nigrescens var. brevispora foram coletados em floresta de Mata Atlântica, respectivamente nos Estados do Paraná e do Rio Grande do Norte. Esses dois táxons foram reportados em listas de diversidade de macrofungos no Brasil; entretanto suas características morfológicas e variações foram, até então, pouco docum

12. A NOVEL RAISIN SEGMENTATION ALGORITHM BASED ON DEEP LEARNING AND MORPHOLOGICAL ANALYSIS
ABSTRACT We propose a segmentation algorithm for raisin extraction. The proposed approach consists of the following aspects. Deep learning is used to predict the number of raisins in each connected region, and the shape features such as the roundness, area, X-axis value for the centroid, Y-axis value for the centroid, axis length and perimeter of each region
