The austenitic stainless steels usually present an excellent combination of corrosion resistance and mechanical properties such as ductility in the annealed condition and high yield strength after cold deformation. Solution annealing in the AISI 304H is recommended before deformation process in order to improve ductility. However, long annealing during solution annealing can cause GG （grain growth） or AGG （abnormal grain growth） in the AISI 304H. In these cases, ductility is strongly decreased. Therefore, GG or AGG must be avoided during solution annealing. In this article, grain growth during solution annealing of the AISI 304H samples was determined. Samples of the AISI 304H were annealed at 1,100 ℃ for solution-annealing times varying from 15 min to 180 min. The results show that AGG took place for samples annealed at 1,100 ℃ for 30 min. In this condition, grain size reached 70 ± 10 μm. After annealing solution at 1,100 ℃ for 180 min, grain size reached 120 ~ 20 μm. In summary, the results shown that solution annealing at 1,100 ℃ even for relatively short annealing promotes the prompt increase of the grain size.

Autonomous Underwater Vehicles (AUVs) are robots able to perform tasks without human intervention (remote operators). Research and development of this class of vehicles has growing, due to the excellent characteristics of the AUVs to operate in different situations. Therefore, this study aims to analyze turbulent single fluid flow over different geometric configurations of an AUV hull, in order to obtain test geometry that generates lower drag force, which reduces the energy consumption of the vehicle, thereby increasing their autonomy during operation. In the numerical analysis was used ANSYS-CFX® 11.0 software, which is a powerful tool for solving problems involving fluid mechanics. Results of the velocity (vectors and streamlines), pressure distribution and drag coefficient are showed and analyzed. Optimum hull geometry was found. Lastly, a relationship between the geometric parameters analyzed and the drag coefficient was obtained.

Background: Stroke has been considered the major cause of chronic disability in the world and ranks among the leading causes of death. Despite the fact that new vascular events often happen and risk factors are the same that Cardiovascular Diseases, secondary prevention through non-pharmacological measures, are not part of the routine physical rehabilitation after stroke. Objective: The aim is to answer the following clinical question: Should aerobic fitness be part of the physical rehabilitation of individuals post-stroke? Methodological Design: The methodology used in the study was an integrative literature review. Inclusion Criteria: Articles in English are published in secondary databases: systematic reviews with or without meta-analysis, which address the question PICO: patient (post-stroke), intervention (aerobic exercise), comparison (with or without aerobic conditioning) the outcome (volume of oxygen consumed peak (VO2peak), quality of life (QoL), morbidity and mortality). Outcomes: VO2peak, QoL, complications and mortality. Analysis of Studies: The methodological quality of included studies is assessed using the tools: PRISMA and R-AMSTAR. Results: There was “good” evidence for the inclusion of aerobic exercise on physical rehabilitation of post-stroke individuals to improve their physical capacity (VO2peak), facilitating the completion of activities of daily living and gait. There was weak evidence on the association of aerobic fitness with positive results on QoL in stroke victims and insufficient results to evaluate the effect of aerobic fitness on the risk of stroke recurrence and mortality. Conclusion: The aerobic conditioning should be included in the rehabilitation of stroke victims.

Cancer is a leading cause of death worldwide, and is estimated to be the cause of 13.1 million deaths in 2030. Breast cancer is the second cancer in the global mortality ranking, considering both sexes. Due to the burden of breast cancer worldwide, this paper aims to present an overview of the main R&D efforts focusing on breast cancer treatment. Patents were retrieved from the Derwent Innovations Index?, which has a specific code for pharmaceuticals related to breast cancer. A total of 423 patent documents filed in recent years were identified, of which 126 are exclusively for breast cancer, 169 for breast cancer and other cancers, and 128 are inventions related to the treatment of cancer and other diseases. The patent documents were classified into two large groups, the first of which had a predominance of claims for antibodies, proteins and polypeptides for use in medication production, while the second focuses on gene therapy, nucleotides and RNA. The country with the majority of priority patent applications was found to be the United States, followed by China and Japan.

The great major applications of thermal isolation are in the strip of drops and averages temperatures （up to 180 ℃）, which is used from aggressive materials to the nature, such as glass wool, rock wool, polystyrene, EPS among others. In spite of the effectiveness in the retention of the flow of heat, such materials possess considerable cost and they are discarded for long years to be decomposed. In that context, to adapt to the world politics about the preservation of the environment, a study began with intention of developing a material composite with thermal properties, originating from insulating industrial residues. In this research, the behavior of this composite was analyzed, when it submitted traction efforts. For this, a term-mechanic was used （DMA）, where the composite was differentiated under variation temperatures. It was also certain that the gradient temperature of the composite was the source of heat, the conductivity and thermal diffusion. Consequently, the function of the answers of the system was possible to be observed with the deformation of the composite with the tension and temperature variation, as well as the temperature gradient for each proportion of the composite.

Background: Hard brunescent nuclei are difficult to chop with traditional techniques, because leathery tough strands may connect the posterior surface and span across the fragments, which poses a challenge to completely divide the nuclei. The ultra-chopping technique was designed to mitigate this issue. Purpose: To compare the intraoperative parameters between Ultra-Chopper and Divide & Conquer Techniques. Setting: This study was performed at Hospital Oftalmológico de Brasília, Brasília, DF, Brazil. Patients and Methods: A prospective, randomized and comparative study. Patients with the diagnosis of dense cataract and surgical extraction programmed were divided into two groups: Ultra-Chopper and Divide & Conquer. Intraoperative data were collected and submitted for the statistical analysis. Results: 36 eyes were included, 19 eyes with Ultra-Chopper and 17 eyes with Divide & Conquer. Groups were statistically equivalent in age and nucleus density. There were no surgical complications. Torsional time and cumulative dissipated energy were significantly reduced in the ultra-chopper group. The ultra-chopper group had less total case time, fluid usage and aspiration (ASP) time. Conclusion: The ultra-chopper tech- nique can reduce ultrasound energy dissipation during cataract surgery, and decrease case time, fluid usage and ASP time.
