title: RELATION BETWEEN IMPACT FACTOR IN ORTHOPEDIC JOURNALS AND LEVEL OF EVIDENCE

description: ABSTRACT Objective: This study aims to assess the quality of articles published in the leading orthopedic surgery journals, by measuring the relation between the impact factor and the number studies with a high level of evidence. Methods: A literature review was performed of articles published in four previously selected journals. A score of journal evidence (RER - Relation between Randomized clinical trials and Systematic reviews) was calculated, considering the number of RCTs and SR published and the total number of full-text articles. Results: The selected journals were JBJS-Am, ASMJ, BJJ-Br and Arthroscopy, with Impact factors of 5.280, 4.362, 3.309 and 3.206 respectively in 2015. In the study, the RER Scores, in the same order, were 9.408, 6.153, 7.456 and 7.779. Conclusion: The journal JBJS-Am is the best available source of information on orthopedic surgery from this point of view. It has the highest Impact Factor and clearly the highest RER Score. On the other hand, we could conclude that the number of published RCT and good quality SR is very low, with less than 10% of all the articles. Level of evidence III, Analyses based on limited alternatives and costs, and poor estimates.

title: Chemometric-Assisted Hydrophilic Interaction Chromatographic Method for the Determination of Gadolinium-Based Magnetic Resonance Imaging Contrast Agent in Liposomes

description: Gadodiamide (Gd-DTPA-BMA) is a gadolinium (Gd) chelate composed of two carboxylate groups of diethylenetriaminepentaacetic acid (DTPA) and two amide groups (BMA). Gd complexes are the most widely used contrast agents in nuclear magnetic resonance. Furthermore, our research group has demonstrated the potential of liposomes containing Gd-DTPA-BMA for cancer therapy. The aim of this study was to develop and validate a chemometric-assisted method by hydrophilic interaction liquid chromatography (HILIC) for determination of Gd-DTPA-BMA in liposomes. The chromatographic conditions obtained were: Sequant® ZIC®-HILIC Merck (150 × 4.6 mm, 3.5 µm, 100 Å) column, mobile phase composed of 5 mmol L-1 ACN/NH4FA, pH 4.5 (60:40 v/v) at 0.6 mL min-1, injection volume of 20 µL, temperature of 30 ºC, and detection at 210 nm. The linear range was of 40 to 120 nmol mL-1. The use of chemometrics allowed obtaining optimal chromatographic parameters, in terms of signal-to-noise ratio, resolution, and asymmetry.

title: Effect of the Incorporation of Micro and Nanocellulose Particles on the Anticorrosive Properties of Epoxy Coatings Applied on Carbon Steel

description: Polymeric coatings may act as a physical barrier between the aggressive ions and the metal substrate. However, prolonged exposure may cause damage to the polymer coating, leading to a continuous reduction of the barrier effect and consequently loss of the corrosion protection. The objective of this study is to determine the effect of aminopropyltriethoxysilane (APS), cellulose and polyaniline emeraldine-salt (PAni ES) in an epoxy coating on the corrosion protection of mild steel. Microcrystalline cellulose (MCC) and cellulose nanowhiskers (CNW) functionalized or not with PAni ES were used and compared. The coating properties were investigated by electrochemical impedance spectroscopy (EIS), salt spray test and scanning electron microscopy (SEM). The surface of the carbon steel, after 1000 h of exposure, did not present evidence of superficial corrosion. Polymer coatings using CNW and PAni ES showed improved corrosion protection properties even after 90 days of immersion in 3.5 wt% NaCl solution. The greatest increase in the corrosion resistance of the coating was found by EIS for the epoxy coating reinforced with CNW functionalized with PAni ES, revealing a synergistic effect of the electroactivity of a conducting polymer and nanosized cellulose particles.

title: Influence of High Current-Density Impulses on the Stress-Strain Response and Microstructural Evolution of the Single Crystal Superalloy CMSX-4

description: Owing to the low formability of single-crystal nickel-based materials, single-crystal components are typically cast. Subsequently, a multi-stage heat treatment is carried out in order to partially compensate the dendrite segregation and to stabilize the precipitated γ’-phase. Such components possess a high resistance to creep at elevated temperatures. Since it is known that electrical impulses can be used to increase the formability of various materials, the potential of an electrical high current-density impulse treatment was evaluated for forming of the high strength nickel-based superalloy CMSX-4. Heat treated and pre-deformed specimens were loaded in compression and subjected to short pulses with a high-current density of 2.3 kA/mm2. Depending on the microstructural state, the material demonstrated work hardening or softening as a consequence of the impulse treatment. In addition, experiments were carried out on crept specimens to test whether the current-impulse treatment can be used to reverse creep-related segregation of alloying elements (raft formation). It was possible to observe a change in the concentration of the elements in the γ/γ’-phase transition following the current-impulse treatment. In particular, a local increase in the γ-forming elements Cr, Co and a decrease in the γ’-forming elements Ta, Ti was observed after the impulse treatment.

title: Prospects of technological applications of sludge from water treatment process of the Negro and Solimões rivers

description: ABSTRACT This work aimed to characterize a by-product of the water treatment process, aiming to insert it into the productive chain of construction. Such by-product was generated in a water treatment plant (WTP), which performs the capture of raw water from the Negro River and, eventually, from the Solimões River. To adapt the water from these sources to the Brazilian standards potable water, a series of physical-chemical processes are carried out at WTP, which lead to the generation of waste called as WTP sludge. Aiming to identify possible technological applications for this by-product, a pertinent bibliographical research was carried out. That way, it was verified that WTP sludge needs pretreatment prior to use. Like this, in order to make the studied WTP sludge an adequate raw material, the same was submitted to drying, grinding and calcination. Before and after such procedures, the sludge characteristics was determined by means of X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD), Thermogravimetry (TG), among other techniques. The characterization results showed that more than 80% of the calcined sludge composition corresponds to silica and aluminum oxides. It is believed that, after processing, the sludge has become an economically and environmentally sustainable raw material, it can be used as partial substitute of clays, in the production of ceramic materials;partial substitute of Portland cement, in pastes, mortars and concretes; mineral additive or artificial pozzolana; geopolymer precursor or aggregate.

title: Spent foundry sand to Portland cement concrete: an aggregate analysis

description: ABSTRACT Spent foundry sand (ADF), one of the wastes from the process of manufacturing parts and components in foundries, is a material with a lot of silica from a mix with natural sand, thinner than natural sand and classified by the Brazilian standard NBR 10004 as waste class II A, non-hazardous and non-inert. An analysis of the ADF was carried out with the objective of its use in concrete because it has interesting physical characteristics to be used as a substitute of the natural fine aggregate in the production of Portland cement-based materials. After the morphological, physical and chemical analysis of the ADF, the use of ADF in Portland cement concrete was evaluated and the fresh performance (workability and fluidity) of these concretes was also tested in several substitution proportions. As final evaluation, mechanical and leaching tests were performed on the ADF concrete and the results indicated that there is loss of mechanical performance with the increase of the ADF content, but this loss can be considered small when compared with the environmental value of the use of the ADF As a substitute for the natural aggregate in the production of concretes.

title: NECROSIS OF THE FEMORAL HEAD AND HEALTH-RELATED QUALITY OF LIFE OF CHILDREN AND ADOLESCENTS

description: ABSTRACT Objective: To verify the impact of avascular necrosis of the femoral head on the quality of life of children and adolescents with Perthes disease and sickle cell disease. Methods: A comparative study including 24 children between eight and 18 years old with avascular necrosis of the femoral head secondary to Perthes disease and sickle cell disease (Group with Necrosis) and 24 children considered asymptomatic (Group without Necrosis). Clinical and sociodemographic data were collected and the PedsQL 4.0 and the Charnley score for hip dysfunction were applied. Results: There was no difference in the overall score and in any domain when comparing the Perthes group (global = 73.1) and the sickle cell disease group (global = 65.9). When comparing the groups with necrosis and without necrosis, the Perthes group had a lower overall score only for the Physical Functioning domain (87.5 versus 68.5); sickle cell disease group had a lower overall score (64.9 versus 79.4) and in the Physical Functioning (68.5 versus 87.5) and School Functioning (62.9 versus 73.7) domains. Conclusion: Avascular necrosis of the femoral head produces lower quality of life scores both in the global evaluation and in the domains Physical Functioning and School Functioning. Necrosis, bilateral lesion, and hip function were found to be associated with the loss of quality of life. Level of Evidence III, Sectional comparative study.
