1. Case for diagnosis. Keloidal cord-like lesion on the leg,
Abstract We report a 74-year-old male presented to an outpatient dermatology clinic in Manaus, Amazonas, with a one-year history of pruritic, keloidal lesions on his left lower extremity. Histopathology showed round structures in reticular dermis. Grocott methenamine silver stain revealed numerous round yeasts with thick double walls, occurring singly or in

2. Presence of ascites in bullfrog breeders reared and kept on a frog farm
RESUMO A ascite é uma condição patológica que se caracteriza pelo extravasamento do líquido dos vasos sanguíneos e por seu acúmulo na cavidade abdominal provocado por uma somatória de fatores. É considerada uma síndrome de caráter multifatorial e, uma vez desencadeado o processo ascítico, esse se torna, na maioria dos casos, irreversível. O obje

3. Kidney anatomy, histology and histometric traits associated to renosomatic index in Gymnotus inaequilabiatus (Gymnotiformes: Gymnotidae)
RESUMO Gymnotus inaequilabiatus é um peixe neotropical amplamente distribuído em áreas marginais de baías. O objetivo deste estudo foi descrever características anatômicas, histológicas e histopatológicas no rim cefálico e exócrino. Análises histométricas e a densidade volumétrica estrutural foram associadas ao índice renossomático (IRS). Frag

4. EXPERIMENTAL INVESTIGATION ON CONCRETE FILLED STEEL TUBULAR COLUMN TO FOUNDATION CONNECTIONS SUBJECTED TO COMBINED AXIAL AND LATERAL CYCLIC LOADING
Abstract This study focuses on performance of CFT column to foundation connections subjected to combined axial and lateral cyclic loading. Experimental investigations were carried out on five specimens with exposed column base and embedded column base connections. The parameters considered were number of stiffeners and embedment depth of CFT column. The forc

5. Effect of Semi-Apical Angle on the Crush Mechanics of Metallic Bi-Tubular Tubes under Dynamic Axial Loading
ABSTRACT Aerospace and automotive industrial advancement demands high energy absorbing structures for the human and equipement safety during transportaion and accidental emergencies. Thin-walled metallic tubes applications in the structures serve the purpose by absorbing energy during such dynamic scenarios. A new concept is presented in this study, involvin

6. Influence of sintering temperature on the development of alumina membrane shaped by centrifugal casting for gas separation
Abstract The development of ceramic membranes for the most diverse separation processes has gained high visibility, mainly due to their better performance in harsh environments in comparison to polymeric materials. Among the different techniques used to prepare tubular ceramic membranes, the centrifugal casting (CC) is interesting for obtaining highly homoge

7. Morphological study of the gastrointestinal tract of Larimichthys crocea (Acanthopterygii: Perciformes)
ABSTRACT The present study aimed to investigate the macroscopic and histological structure of the gastrointestinal tract (GIT) of Larimichthys crocea (Richardson, 1846). It consists of esophagus, stomach regions, pyloric caeca, intestinal regions, and rectum. Sixteen tubular light yellowish pyloric caeca of similar sizes were observed in all individuals. The

8. The dispersion curve applied in guided wave propagation in prismatic rods.
Abstract The early detection of failures in structures is a subject of great interest in engineering; several of these techniques are linked with the elastic wave propagation, using guided waves is one of these alternatives. Several structures of interest in engineering are laminar arrangements; the wave propagation in this type of structures depends not on

9. Axial Crushing of Uni-Sectional Bi-Tubular Inner Tubes with Multiple Outer Cross-Sections
Abstract Increase of energy absorption along with smooth load displacement curve, reduced peak force and high mean crushing force is the key in the modern dynamic design of structures. In this regard, a new metallic tubular configuration consisting of uni-sectional bi-tubular inner tubes, with outer tubes of multiple varied cross-sections is proposed and cru

10. Influence of shear lag coefficienton circular hollow sections with bolted sleeve connections
Abstract The circular hollow sections (CHS) are being widely employed in steel structures around the world, increasing the development of new researches. This article proposes an innovative connection model for circular hollow sections that facilitates and reduces the assembly cost of hollow section structures. The proposed connection is a tube sleeve, used

11. Temperature field of concrete-filled steel tubular columns in fire
Abstract The composite structures formed by the association of steel profiles with concrete have shown to be an advantageous alternative, improving the behavior of the steel structures concerning their load capacity, stiffness, and durability, under fire conditions. The concrete-filled tubular columns have become an attractive alternative for the civil const

12. Probabilistic analysis of stress intensity factor (SIF) and degree of bending (DoB) in axially loaded tubular K-joints of offshore structures
Abstract The stress intensity factor (SIF) and the degree of bending (DoB) are among the crucial parameters in evaluating the fatigue reliability of offshore tubular joints based on the fracture mechanics (FM) approach. The value of SIF is a function of the crack size, nominal stress, and two modifying coefficients known as the crack shape factor (Yc) and ge
