The National High School Examination (ENEM) is an evaluative and selective tool for students to enter higher education. Federal Institutes of Education, Science Technology (FIs) are institutions created by the government with objective training competent professionals. purpose this study compare content Physics questions between years 2014 2018 curriculum technical chemistry course at Institute...

In this article we discuss the theme of envy given its importance in analytical work, especially when it presents itself as a central point within analysis work. I tried to handle somewhat broad view, quoting some authors who enlighten less evident aspects expression, emphasizing personal damage coexistence presence self. We bring cutouts our work with Guida, 45-year-old woman present traces he...

OBJECTIVE To investigate the biomechanical properties of the percutaneous compression plating system for intertrochanteric hip fractures. DESIGN A biomechanical laboratory investigation on human cadaveric upper femora was conducted. SETTING Biomechanical laboratory. PATIENTS Sixteen femora from cadavers of patients aged 60 to 85 years. INTERVENTION An intertrochanteric fracture was perf...

This study compared patients who underwent treatment with short or long cephalomedullary nails with integrated cephalocervical screws and linear compression. Patients with AO/OTA 31-A2 or A3 pertrochanteric fractures treated with either short (n=72) or long (n=97) InterTAN (Smith & Nephew, Memphis, Tennessee) cephalomedullary nails were reviewed. Information on perioperative measures (estimated...

Aerospace and aircraft companies follow a pyramidal structure of testing, ranging from specimen tests to full-scale tests, for structural design. At the base level, open hole strength evaluation is one qualification procedures composite components. The holes are made in components accommodate bolts rivets order assemble parts into single unit. Holes component also used fulfill functional requir...

This paper investigates the moments and stress resultants from infinite FG laminates with different polygonal cutouts subject to uniaxial tensile load. The analytical solution used for the calculation of stress resultants and moments is the basis of the complex-variable method and conformal mapping function. The impact of various factors, namely cutout orientation angle, cutout aspect ratio as ...

We proposed a local one-sided rubber bulging method of metal tubes to evaluate various strain paths at an aimed portion and measured the forming limit strains place occurrence necking under biaxial deformation. Using this method, since is used give pressure from inner side tube, no sealing mechanisms were necessary unlike during hydraulic bulging. An opening was prepared in front die locally bu...

Welding procedures for repairing corroded tubular structures are commonly used; however, composite material repairs becoming popular since they do not use heat sources that might cause accidents. This paper provides a detailed description of the CFRP patch repair application in steel members with circular perforation originated from prolonged corrosion process. The results experimental tests on...
