13. Use of osmoregulatory ability to predict invasiveness of the Indo-Pacific swimming crab Charybdis hellerii (A. Milne-Edwards, 1867) an invader in Southern Brazil
Abstract The Indo-Pacific swimming crab Charybdis hellerii (A. Milne-Edwards, 1867) is native to the Indo-Pacific Ocean, and occurs as an invasive species along the Eastern American coast, where it was probably introduced in ballast water. The present study evaluated the osmoregulation and salinity tolerance of C. hellerii in Paranaguá Bay, Paraná, Brazil,

14. Impact responses of slender composite plates for bird-strike testing of fan blades
Abstract Bird-strike failure of fan blades is one of the basic challenges for the safety of aircraft engines. Simplified slender blade-like plates are always used to evaluate the impact-induced damage mechanism at design stage. One undesirable issue is the failure at the root of clamped slender plates, which cannot recover the real case of twisted blades. Fo

15. Correlation between Myocardial Velocity Measured using Tissue Doppler Imaging in the Left Ventricular Lead-Implanted Segment and Response to Cardiac Resynchronization Therapy
OBJECTIVES: This study investigated whether tissue Doppler imaging parameters, especially the peak systolic velocity of the left ventricular lead-implanted segment (Ss), affect cardiac resynchronization therapy response. METHODS: In this case-control study, 110 enrolled patients were divided into cases (responder group, n=65) and controls (nonresponder gro

17. Adjustable sling for the treatment of post-prostatectomy urinary incontinence: systematic review and meta-analysis
RESUMO A incontinência urinária pós-prostatectomia tem importante impacto negativo na qualidade de vida do portador. O tratamento cirúrgico inclui slings masculinos e, entre os diversos modelos, os slings ajustáveis. O objetivo deste estudo foi avaliar a efetividade e a segurança do sling ajustável no tratamento da incontinência urinária pós-prosta

18. Risk of Obstructive Sleep Apnea and Echocardiographic Parameters
Resumo Fundamento: A apneia obstrutiva do sono (AOS) é um transtorno crônico, progressivo, com alta morbimortalidade e associado às doenças cardiovasculares (DCV), entre elas a insuficiência cardíaca (IC). As alterações fisiopatológicas relacionadas com a AOS podem impactar diretamente a função diastólica do ventrículo esquerdo. Objetivo: Esti

19. Synergistic Effect of Disease Severity, Anxiety Symptoms and Elderly Age on the Quality of Life of Outpatients with Heart Failure
Resumo Fundamento: A insuficiência cardíaca (IC) é uma síndrome multifatorial com repercussões sobre a qualidade de vida (QV). Objetivo: Investigar os principais fatores que interagem e pioram a qualidade de vida de pacientes ambulatoriais com IC. Métodos: Estudo transversal observacional com 99 pacientes, de ambos os sexos, atendidos no ambulatóri

20. Fragmentation model for the tensile response of unidirectional composites based on the critical number of fiber breaks and the correction of the fiber-matrix interfacial strength.
Abstract A fragmentation model based on global load sharing (GLS) theory is developed to obtain stress-strain curves that describe the mechanical behavior of unidirectional composites. The model is named C N B + τ * because it is based on the Critical Number of Breaks model (CNB) and on the correction of the fiber matrix interfacial strength, τ *

21. Crack and mechanical behavior of CFRP plate-reinforced bridge roofs under high temperature with different anchoring measures
Abstract This paper investigates the crack and mechanical behavior of CFRP plate-reinforced bridge roof under high temperature with different anchoring measures. Six CFRP-reinforced test beams with different anchoring schemes were designed and constructed. The beam specimens, after the high temperature effects, were tested under four-point bending loads. The

22. Simulation of tailings release in dam break scenarios using physical models
Abstract This article presents an experimental study performed to evaluate the volume of material released from the reservoir during a tailings dam failure event using models. To verify the influence of the parameters related to the breach geometry and the undrained shear strength (Su) in a failure event, 20 scenarios were simulated considering the absence o

23. Effects of gene therapy on cardiovascular symptoms of lysosomal storage diseases
Abstract Lysosomal storage diseases (LSDs) are inherited conditions caused by impaired lysosomal function and consequent substrate storage, leading to a range of clinical manifestations, including cardiovascular disease. This may lead to significant symptoms and even cardiac failure, which is an important cause of death among patients. Currently available tr

24. O paradoxo do tratado constitucional europeu: entre o planejamento e a evolução da Europa comunitária
Resumo A introdução da tentativa de um Tratado Constitucional Europeu no sistema do Direito coloca em xeque duas das mais enraizadas instituições jurídicas do Ocidente: as Constituições e os Tratados, já que ambas partem, desde o ponto de vista da doutrina tradicional, de pressupostos conceituais diferenciados. O paradoxo está ligado às condições
