13. Recycling and Mechanical Characterization of Polymer Blends Present in Printers
More and more electronic devices are being produced and most of them are disposed of improperly. In addition, as they contain heavy metals and toxic substances in their composition, the environmental impact increases. This work aims to study the recycling of polymers present in e-waste through the mechanical characterization of polymer blends produced with t

14. ISCHIOFEMORAL IMPINGEMENT: ASSESSMENT OF MRI FINDINGS AND THEIR RELIABILITY
ABSTRACT Objective: To evaluate the Magnetic Resonance Imaging (MRI) findings and their validity in patients with ischiofemoral impingement syndrome (IFI) . Methods: We retrospectively analyzed 55 hips. MRI findings of 30 hips were consistent with IFI syndrome. Twenty five hips had no MRI findings consistent with IFI syndrome. We compared the ischiofemora

15. PRP IN THE TREATMENT OF TROCHANTERIC SYNDROME: A PILOT STUDY
ABSTRACT Objective: To compare the efficacy of platelet rich plasma (PRP) against corticosteroid on the treatment of trochanteric pain syndrome . Methods: From July 2011 to November 2012, eighteen patients (20 hips) with trochanter pain syndrome were randomized in two groups and treated with platelet rich plasma or triamcinolone infiltration guided by ult

16. CADAVERIC STUDY ON THE LEARNING CURVE OF THE TWO-APPROACH GANZ PERIACETABULAR OSTEOTOMY
Objective : The Bernese periacetabular osteotomy (PAO) is a widely used technique for the treatment of non-arthritic, dysplastic, painful hips. It is considered a highly complex procedure with a steep learning curve. In an attempt to minimize complications, a double anterior-posterior approach has been described. We report on our experience while performing

17. BLEEDING OF FEMORAL HEAD DURING TOTAL HIP ARTHROPLASTY FOR OSTEOARTHROSIS
Objective:To evaluate the bleeding of the femoral head on hip osteoarthritis in patients who underwent total hip arthroplasty.Methods:One hundred and three hips affected by primary hip osteoarthritis were evaluated. After surgical dislocation, the femoral head was divided into four quadrants, and micro perforations were made in order to observe and assess th

18. Solvent Effect on the Morphology of Lamellar Nanocomposites Based on HIPS
In this study, hybrid nanocomposites based on HIPS, high-impact polystyrene, were prepared in chloroform and in a 1:1 mixture of toluene and chloroform varying the quantity of organophilic montmorillonite. The morphology of the hybrid materials was investigated by X-ray diffraction (XRD) and proton relaxometry, determined in a low-field 1H nuclear magnetic r

19. Prevalence of osteoporosis in patients awaiting total hip arthroplasty
Objective: To evaluate the prevalence of osteoporosis in patients awaiting total hip arthroplasty.Method: Twenty-nine patients diagnosed with hip osteoarthritis awaiting primary total arthroplasty of the hip answered WOMAC questionnaire, VAS and questions about habits, osteoporosis and related diseases. Bone mineral densitometry of the lumbar spine and hips

20. Mejoramiento de las propiedades de tensión en WPC de LDPE: HIPS/fibra natural mediante entrecruzamiento con DCP
Straight Retamo Fiber (telinemonspessulana) was mixed in a polymer matrix formed by low density polyethylene (LDPE) and high impact polystyrene (HIPS) in a 70:30 ratio. The natural fiber was subjected to size reduction between 1700 and 850 µm; surface treatment mercerization was performed; the moisture content was 0.17%. The thermo gravimetric analysis (TGA

21. The use of spect/ct in the evaluation of heterotopic ossification in para/tetraplegics
Objective: To evaluate the stage of maturation and the metabolism of neurogenic heterotopic ossification by using SPECT/CT. Methods: A total of 12 medical records of patients with spinal cord injury, all of them classified according to the ASIA protocol (disability scale from the American Spinal Injury Association) in complete lesion (A) and partial le

22. Intercalação por solução de poliestireno de alto impacto em montmorilonita organofílica - obtenção e caracterização
Neste trabalho foram preparados e avaliados nanocompósitos de poliestireno de alto impacto (HIPS) e nanoargila. Três tipos de argila montmorilonita modificadas com sal quaternário de amônio (OMMT), denominadas de S4, S7 e B8, e uma argila sódica NT-25 foram empregadas para a obtenção dos nanomateriais. A inserção da argila organofílica no HIPS foi

23. Influence of reaction operation conditions on the final properties of high impact polystyrene (hips)
The main objective of the present work is to analyze the influence of some important operational reaction parameters (agitation speed, polybutadiene - PB - content and initiator concentration) on the final properties of High Impact Polystyrene (HIPS) produced in bulk. Variable effects are analyzed both qualitatively and quantitatively with the help of a frac

24. High and specialty-related musculoskeletal disorders afflict dental professionals even since early training years
OBJECTIVE: To determine how early musculoskeletal disorders (MSDs) develop in dental professionals and to explore the potential differences among distinct dental specialties. MATERIAL AND METHODS: 271 dental postgraduates majoring in five dental specialties were recruited, i.e., orthodontics, prosthodontics, endodontics, periodontics and alveolar surgery.
