The aim of this study was to compare the effects of combined (CT; strength plus aerobic) and functional training (FT) on the body composition and metabolic profile with a similar training load in postmenopausal women. The participants were divided into three groups: CT (n= 20), FT (n= 17), and control group (CG, n= 15). The trunk FM, fat mass (FM), percentage of FM (FM%), and fat-free mass were estimated by dual-energy X-ray absorptiometry. The metabolic profile, glucose, triacylglycerol, total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol (LDL-c) were assessed. There were main effects of time in trunk fat, FM, and FM% (P< 0.05). There were statistically significant interaction for FM (P= 0.015), FM% (P= 0.017) with lower values for CT group. For LDL-c, there was significant interaction (P= 0.002) with greater values for FT group in relation to CG and CT. Furthermore, when performed the post hoc test on the “mean absolute differences” (Δ), it can observed statistically significant difference between FT, CT, and CG (-13.0± 16.5 mg/dL vs. 4.8± 18.4 mg/dL vs. 9.2± 18.8 mg/dL, P< 0.05). In conclusion, when training loads are equivalent CT potentiated a reduction in FM and FM%, however, only FT reduced LDL-c in postmenopausal women.

This study verified the effects of a physical exercise program performed at Basic Healthcare Units on the body composition and functional capacity of women over 50 years old and to compare these variables according to age. Forty-eight women (age, 65.4± 7.3 years) were assessed. The program lasted 20 weeks, and was conducted 2 times per week, 60 min/day. Body mass and height were collected and body mass index (BMI) was calculated. Bioelectrical impedance was used to estimate fat mass and fat free mass. Functional capacities: handgrip test, Timed Up and Go (TUG) test, and Guralnick test were assessment. Weight (68.7± 12.5 [pre]× 66.8± 12.5 [post], P< 0.001), BMI (28.5± 4.1 kg/ m2 [pre]× 27.6± 4.0 kg/m2 [post], P< 0.001), and fat mass (28.4± 7.8 kg [pre]× 26.4± 7.3 kg [post], P< 0.001) were decreased. For functional capacity, handgrip (21.2± 5.8 kg [pre]× 22.9± 6.9 kg [post], P= 0.014), lower limb strength (12.0± 3.0 sec [pre]× 8.5± 2.2 sec [post], P< 0.001), TUG (8.4 ±1.5 sec [pre] ×7.6 ±1.1 se [post], P<0.001) and Guralnik tests (10.6± 1.6 [pre]× 11.8± 0.5 [post], P< 0.001) were improved. 20 weeks of exercise program performed at Basic Healthcare Units decreased body fat and improvement of functional capacity of women over 50 years old and there was difference according to age only on the body composition variables.
Seismic performance assessment of pre-engineered steel buildings on the west coast of Canada
Fabrício Bagatini-Cachuço,T.Y. Yang 국제구조공학회 2021 Steel and Composite Structures, An International J Vol.41 No.3
This paper focuses on the seismic performance of typical pre-engineered steel buildings (PSB) on the west coast of Canada. PSB are widely adopted for commercial and industrial long span low-rise constructions. Their structural system consists of a moment resisting frame made of built-up tapered I-beam elements, which often have slender and/or non-compact sections to minimize steel consumption. Typical seismic design of PSB consists of elastic analysis with force reduction factors (FRF) that assume some ductility. However, failure mechanisms in PSB are usually governed by flange local buckling and lateral torsional buckling, which might not provide the expected ductility. This paper presents an extensive series of numerical analyses to evaluate the seismic performance of four PSB prototypes designed for the city of Victoria on the west coast of Canada. Prototypes have similar general dimensions, while members’ sizes vary due to usage of different FRF. A finite element model (FEM) has been calibrated based on experiments to capture the post-buckling response of tapered built-up steel elements under cyclic load. Furthermore, seismic performance of each PSB prototype has been assessed with incremental dynamic analysis procedure. Structural characteristics, such as ductility and overstrength, are identified. In addition, the prototypes’ probability of collapse is assessed under a set of 33 ground motions from multiple sources of hazard. The resultant collapse margin ratio is compared with the acceptance criterion per FEMA P695 recommendation. The study concludes proposing FRF=1.3 for the efficient design PSB on the west coast of Canada.

Objectives: This study investigated the effects of physically damaged and resin-contaminated tips on radiant emittance, comparing them with new undamaged, non-contaminated tips using 3 pieces of spectrophotometric laboratory equipment. Materials and Methods: Nine tips with damage and/or resin contaminants from actual clinical situations were compared with a new tip without damage or contamination (control group). The radiant emittance was recorded using 3 spectrophotometric methods: a laboratory-grade thermopile, a laboratory-grade integrating sphere, and a portable light collector (checkMARC). Results: A significant difference between the laboratory-grade thermopile and the laboratory-grade integrating sphere was found when the radiant emittance values of the control or damaged/contaminated tips were investigated (p < 0.05), but both methods were comparable to checkMARC (p > 0.05). Regardless of the method used to quantify the light output, the mean radiant emittance values of the damaged/contaminated tips were significantly lower than those of the control (p < 0.05). The beam profile of the damaged/contaminated tips was less homogeneous than that of the control. Conclusions: Damaged/contaminated tips can reduce the radiant emittance output and the homogeneity of the beam, which may affect the energy delivered to composite restorations. The checkMARC spectrophotometer device can be used in dental offices, as it provided values close to those produced by a laboratory-grade integrated sphere spectrophotometer. Dentists should assess the radiant emittance of their light-curing units to ensure optimal curing in photoactivated, resin-based materials.

In this work, the effect of the growth rate (VL) and cooling rate (TR), primary dendritic arm spacing (1) and Al2Cu intermetallic phase on the microhardness was investigated during transient horizontal directional solidification of Al-3wt%Cu and Al-8wt%Cu alloys. Microstructural characterization of the investigated alloys was performed using traditional techniques of metallography, optical and SEM microscopy and X-Ray diffraction. The microhardness evolution as a function of the thermal and microstructural parameters (VL, TR, and 1) was evaluated using power and Hall-Petch type experimental laws, which were compared with other laws in the literature. In order to examine the effect of the Al2Cu intermetallic phase, microhardness measurements were performed in interdendritic regions. Finally, a comparative analysis was performed between the experimental data of this work and theoretical models from the literature that have been proposed to predict primary dendrite arm spacing, which have been tested in numerous works considering upward directional solidification.

Reinforced concrete structures are widely used in civil engineering projects around the world in different designs. Due to the great evolution in computational equipment and numerical methods, structural analysis has become more and more reliable, and in turn more closely approximates reality. Thus among the many numerical methods used to carry out these types of analyses, the finite element method has been highlighted as an optimized tool option, combined with the non-linear and linear analysis techniques of structures. In this paper, the behavior of reinforced concrete beams was analyzed in two different configurations: i) with welding and ii) conventionally lashed stirrups using annealed wire. The structures were subjected to normal and tangential forces up to the limit of their bending resistance capacities to observe the cracking process and growth of the concrete structure. This study was undertaken to evaluate the effectiveness of welded wire fabric as shear reinforcement in concrete prismatic beams under static loading conditions. Experimental analysis was carried out in order compare the maximum load of both configurations, the experimental load-time profile applied in the first configuration was used to reproduce the same loading conditions in the numerical simulations. Thus, comparisons between the numerical and experimental results of the welded frame beam show that the proposed model can estimate the concrete strength and failure behavior accurately.

Susceptibility to chlorimuron varies according to soybean genotype. STS® (sulfonylurea-tolerant soybean) presents a high tolerance to some sulfonylureas; this feature is determined by semi-dominants alleles, Als1 and Als2. Experiments were conducted in the field for four seasons with two cultivars for season to evaluate the selectivity of chlorimuron rates in post-emergency (V4) of glyphosate-tolerant and sulfonylurea-tolerant soybean. Data analysis made it possible to infer that there was no significant effect on the productivity of the cultivars when they received application in post-emergency, of chlorimuron at the doses used (0, 15, 30, 45, 60, 75, and 90 g ai ha-1). The maximum recommended rate for non-STS cultivars of chlorimuron is 20 g ai ha-1, or 4.5 times less than the maximum rate employed in this study. The soybean cultivars CD 250 RR/STS, CD 236 RR/STS, CD 2630 RR/STS, and BMX Turbo RR/STS were tolerant to the application, in post-emergency (V4) of the herbicide chlorimuron, until the rate of 90 g ai ha-1.
