AbstractThis study examined the acute effects of exposure to moderate altitude on factors associated with muscular adaptations following whole‐body hypertrophy‐oriented resistance training (R T) sessions. Thirteen resistance‐trained males completed both counterbalanced standard hypertrophic R T sessions (3 sets × 10RM, 2 min rest) at moderate‐altitude (H; 2320 m asl) and under normoxic conditions (N; <700 m asl). Participants rested 72 h between training sessions. Before and after the exercise session, blood samples were obtained for determination of metabolites and ions (lactate, inorganic phosphate, liquid carbon dioxide and calcium) and hormones (testosterone and growth hormone). Session‐related performance and perception of effort (s‐RPE) were also monitored. Results showed no meaningful differences in performance or s‐RPE (8.5 ± 1.4 vs 8.6 ± 0.8 respectively for N and H; p = 0.603). All blood variables displayed statistically significant changes throughout the recovery period compared to basal levels (p < 0.05), except for the testosterone. However, no altitude effect was observed in maximal blood lactate, calcium or anabolic hormones (p > 0.05). The reduction observed in the liquid carbon dioxide concentration in H (21.11 ± 1.46 vs 16.19 ± 1.61 mmol·l−1) seems compatible with an increase in buffering capacity. Compared to N, inorganic phosphate displayed lower recovery values after the R T in H (2.89 ± 0.64 vs 2.23 ± 0.60 mg dl−1; p = 0.007). The results of this study do not support an accentuated effect of acute moderate terrestrial hypoxia on metabolic and hormonal factors linked to muscle growth during hypertrophic resistance training.

Published: November 2019

Abstract
High-power, nanosecond, pulsed-laser ablation in liquids enables the continuous synthesis of highly pure colloidal nanoparticles (NPs) at an application-relevant scale. The gained mass-weighted particle size distribution is however often reported to be broad, requiring post treatment like centrifugation to remove undesired particle size fractions. To date, available centrifugation techniques are generally discontinuous, limiting the throughput and hindering economic upscaling. Hence, throughout this paper, a scalable, continuously operating centrifugation of laser-generated platinum NPs in a tubular bowl centrifuge is reported for the first time. To that end, using a 121 W ns-laser, the continuous production of a colloidal suspension of NPs, yet with broad particle size distribution has been employed, yielding productivities of 1–2 g h−1 for gold, silver, and platinum. The power-specific productivities (Au: 18 mg h−1 W−1, Pt: 13 mg h−1 W−1, Ag: 8 mg h−1 W−1, Ni: 6 mg h−1 W−1) are far higher than reported before. Subsequent downstream integration of a continuously operating tubular bowl centrifuge was successfully achieved for Pt NPs allowing the removal of undesired particle size with high throughput. By means of a systematic study of relevant centrifugation parameters involved, effective size optimization and respective size sharpness parameters for a maximum Pt NP diameter of 10 nm are reported. The results of the experimental centrifugation of laser-generated Pt NPs were in excellent agreement with the theoretically calculated cut-off diameter. After centrifugation with optimized parameters (residence time of 5 min; g-force of 38,454 g), the polydispersity indices of the Pt NPs size distributions were reduced by a factor of six, and high monodispersity was observed.

Published: November 2019

Abstract
The spatial environment is the carrier of urban crime. Improper spatial environment provides conditions and opportunities for urban crime, which is the main factor that triggers residents’ fear of victimization. With the aid of the “CPTED” and the “vulnerable to crime” theories, the author proposes that the spatial position, the spatial morphology and the spatial atmosphere are three physical properties of buildings’ outside environment that affect residents’ fear of victimization, after teasing out the environmental characters that influence residents’ fear of victimization, such as accessibility, visibility, identifiability, territoriality, positivity and imagery, etc. The author puts forwards some defense safety design strategies on weakening residents’ fear of victimization for a typical semi-gated residential community in Changchun.

Published: November 2019

Abstract
Beam element is often used for simulation of frames, and the two-dimensional element is used for simulation of shear walls and slabs in structural analysis. This kind of method can be used for most of the conventional structures, but for the super-large section of super-tall buildings or the complex geometry structural members, this simplified may produce significant numerical error. In this paper, three-dimensional solid element is used to simulate the special shape members in a framework, and the embedding of model processing, multipoint constraints and other special constraint forms are introduced, which provides a new idea for engineers to use three-dimensional solid element to simulate the building structures. The results of the example show that the simplification of the special members in the structure will not only have a significant impact on the local results of the structure, but also may cause analysis bias on the overall results of the structure.

Published: November 2019

Abstract
The difference of cold resistance between aboveground and underground parts was compared by measuring the growth and cold-resistance physiology of dormancy-released Sedum aizoon L. seedling with sprout at -5, 0 and 5 degrees Celsius respectively. The results showed that with the decreasing temperature, the plant height and root length all showed a downward trend, and the plant height decreased more than root length. The aboveground fresh weight showed an upward trend, while the underground fresh weight showed a downward first and then upward trend. The relative electrical conductivity (REC), tissue water content, total soluble sugar and free proline content all showed an upward trend, while malondialdehyde (MDA) content showed a downward trend in leaves. The content of soluble protein showed a downward first and then upward trend in leaves. The changing trend of roots was the same as leaves in REC, total soluble sugar and soluble protein content, but the REC of roots increased less than leaves. There was no significant change in tissue water content, free proline and MDA content in roots. At the same low temperature, roots were all higher than leaves in the content of total soluble sugar and soluble protein, while the tissue water content and MDA content were the contrary. In conclusion, the cold resistance of the underground part was stronger than aboveground part in Sedum aizoon L. seedling with sprout.

Published: November 2019

Abstract
Aluminum (Al) alloy welded structures are widely used in industry and daily life, while welded joints are easily produced defects, including macro and microscopic defects. It is a hot topic to study the effect of microscopic defects on the properties of welded joints. In this paper, a two-dimensional rate-dependent crystal plasticity model is established by using a numerical model, and then the mechanical behaviors of welded joints with micropores under tensile load is simulated in a mesoscale. The mechanical properties are described by varying the sizes and positions of micropores. The stress-strain response, equivalent plastic strain and equivalent stress distributions of polycrystalline Al alloy welded joints with different micropores are obtained. The results verify that those micropores have certain impact on the start of slip systems and the ability of resisting the deformation of polycrystalline joints. Compared with the positions of micropores, the sizes of micropores have a greater impact on the mechanical properties of the polycrystalline joints.

Published: November 2019

Abstract
The effects of different concentrations of selenium (0.00, 0.05, 0.10, 0.25, 0.50, 1.00, 2.00 mg/L) on the stress resistance of grape seedlings were studied by pot experiment. The results showed that the proline content in different parts of grape seedlings showed an increasing trend with the increase of selenium concentration. The activities of SOD, POD and CAT, as well as the relative conductivity, malondialdehyde and soluble protein content of grape seedlings increased first and then decreased with the increase of exogenous selenium concentration. When the concentration of selenium was 0.50 mg/L, the antioxidant enzyme activity and the content of permeate in grape seedlings reached the maximum. In summary, low concentration of selenium can effectively improve the stress resistance of grape seedlings, but when the concentration of selenium is higher than 0.50 mg/L, it has a toxic effect on grape seedlings.
