Objective: To evaluate the prevalence of hand osteoarthritis (hOA) in a population with knee osteoarthritis (KOA) at baseline and one year following the administration of a multi-professional OA educational program correlating symptoms and changes in BMI with function questionnaires of the upper limbs and direct grip strength measurements. Design: Epidemiological study of the prevalence of hand OA in patients with knee osteoarthritis. The Stanford Health Assessment Questionnaire instruments (HAQ);Disabilities of the Arm, Shoulder and Hand* (DASH);grip strength;and finger pinch were utilized, and the upper limbs symptoms were verified at baseline and one year following the educational program. Results: The prevalence of hOA was 23.7% at baseline and 47.4% at one year (incidence of 31.8% per year). The HAQ indicated that patients who did not alter or increased their BMI experienced worsened global strength, whereas patients who reduced BMI improved global strength (p = 0.041). Patients with higher initial BMIs experienced less improvement in the HAQ (r = -0.148, p = 0.041). The DASH results improved, but the right and left tripod grip worsened in all patients, irrespective of BMI change (p < 0.05) or symptoms at baseline and reassessment (p < 0.05). Pinch strength (right and left tripod and left pulp-pulp) was higher in patients without symptoms at baseline (p = 0.048, p = 0.045 and 0.033, respectively). Conclusions: The prevalence of hand OA increased for patients with OA undergoing an educational program irrespective of improved upper function and regardless of BMI change. Patients who decreased their BMI improved their global strength.

Background: Osteoarthritis (OA) is a disabling disease that can affect 6% to 12% of the adult population and more than a third of people over 65 years of age. Purpose: To assess whether a group of people with hand osteoarthritis (hOA) who received different types of treatment improved their function after two years of follow-up. Method: The entire sample (n = 97) underwent three follow-up assessments regarding anthropometric parameters of the upper limbs and ability to perform functional activities. Subsequently, the sample was divided into two groups for the intervention periods, called the First Period (n = 73) and the Second Period (n = 24);the First Period kept the same protocol with orientations, and the Second Period went to an intervention with orientation strength exercises and use of orthosis. Findings: In the separate analysis of the three questions of the DASH pain module, no differences were found between the assessment moments for groups of guidelines, treatment, or symptoms. Significant effects were observed for F(2, 162) = 3.5, p = 0.033, η2 = 0.04, and interaction for moments and intervention F(2, 162) = 4.3, p = 0.016, η2 = 0.05. Implications: It can be concluded that only guidance treatment does not benefit patients with hand osteoarthritis. In contrast, guidance, exercise, and orthosis treatment can significantly improve the disease.

Saturated anisotropic hydraulic conductivity of a compacted lateritic soil

引用

Journal of Rock Mechanics and Geotechnical Engineering 2018年第5期10卷 986-991页

作者： Roberto Aguiar dos santos Edmundo Rogerio Esquivel Varzea Grande Institute of Engineering Federal University of Mato Grosso Cuiaba Mato Grosso Brazil Sao Carlos School of Engineering University of Sao Paulo Sao Carlos Sao Paulo Brazil

This study focuses on the saturated anisotropic hydraulic conductivity of a compacted lateritic clayey sandy soil. The effects of the molding water content and the confining stress on the anisotropic hydraulic conductivity are investigated. The hydraulic conductivity is measured with a flexible-wall permeameter. Samples are dynamically compacted into the three compaction states of a standard Proctor compaction curve： the dry branch, optimum water content and wet branch. Depending on the molding water content and confining stress, the hydraulic conductivity may increase or decrease. In addition, the results indicate that, when the samples are compacted to the optimum water content, lower hydraulic conductivity is obtained, except at a confining stress equal to 50 kPa. The increase of the confining stress decreases the hydraulic conductivity for each of the evaluated compaction states. In the wet branch, horizontal hy- draulic conductivity is about 8 times higher than the vertical value. The anisotropic hydraulic conduc- tivities of the dry and wet branches decrease when the confining stress increases, and the opposite is observed in the optimum water content state.

Influence of a non-rotating shoulder on heat generation,microstructure and mechanical properties of dissimilar AA2024/AA7050 FSW joints

引用

Journal of Materials Science & Technology 2018年第1期34卷 119-127页

作者： Alessandro Barbini Jan Carstensen Jorge F.dos santos Helmholtz-Zentrum Geesthacht Institute of Materials Research Materials Mechanics Solid-State Joining Processes (WMP)

Friction stir welding （FSW） and stationary shoulder friction stir welding （SSFSW） were carried out for the butt joining of dissimilar AA2024-T3 and AA7050-T7651 aluminium alloys with thicknesses of 2 mm. A comparison between the two processes was performed by varying the welding speed while keeping the rotational speed constant, Through the analysis of the force and torque produced during welding and a simple analytical model, it was possible to show that in SSFSW there is more effective coupling with the tool and the heat produced is more efficiently distributed. This process decreases both the welding area and the diffusion at the interface of the two alloys compared with FSW. The minimum microhardness occurred at the advancing side （AS） at the interface between the thermo-mechanically affected zone （TMAZ） and the stir zone （SZ） in both processes, although the decrease was more gradual in SSFSW. This interface is also where all specimens failed for both welding technologies. An increase in tensile strength was measured in SSFSW compared with standard FSW. Furthermore, it was possible to establish the mechanical performance of the material in the fracture zone using digital image correlation.

Proposals of SPT-CPT and DPL-CPT correlations for sandy soils in Brazil

引用

Journal of Rock Mechanics and Geotechnical Engineering 2017年第6期9卷 1152-1158页

作者： Mirella Dalvi dos santos Kátia Vanessa Bicalho Universidade Federal do Espírito Santo VitóriaBrazil

Field tests in geotechnical engineering are fundamental for identification of the underground *** standard penetration test(SPT) is the most commonly used geotechnical approach. There has been an increase both in the use and application of the in situ tests: cone penetration test(CPT) and dynamic probing(DP). Several empirical SPT-CPT and dynamic probing light(DPL)-CPT correlations for sandy soils have been discussed in the literature. New SPT-CPT and DPL-CPT correlations for the sandy soils of the city of Vitoria, in the southeast of Brazil, are suggested in this paper. Statistical analyses to evaluate the quality of the data used are performed, and the suggested correlations are validated with several previous published datasets. The paper also provides some insights into SPT-CPT correlations and soil characteristics(i.e. the mean particle size and the fines fraction of the soil).
