Published: August 2018

Abstract
Two T6 (500°C × 3 h, water quenching and 210°C × 6 h, air cooling) samples of Al-13Si-5Cu-2Ni-1Mg alloy were furture heated to 350°C and 420°C, respectively for various times. The tensile strength of the alloy, measured at both room temperature and 350°C is observed to abnormally increase, especially for the samples that were heated to 420°C. Al11Cu5Mn3 nanoparticles that form stably during these heating processes exhibit a higher volume fraction after the exposure to 420°C than that obtained by the exposure to 350°C. These nanoparticles were responsible for enhancing the alloy's tensile properties because of the precipitation strengthening effect of the second nano-phase.

Published: August 2018

Abstract
We obtained ZnO crystals with different morphologies through a simple hydrothermal method by adjusting the solution pH. We characterized the ZnO crystals by means of scanning electron microscopy and found several different morphologies, including strip-like, flake-like, cone-like, and six-sided prism shaped particles. The reaction mechanism of the ZnO crystal growth was also investigated. The absorption properties of the ZnO samples were studied using ultraviolet–visible spectroscopy. The studies of the optical properties indicated that the absorption peaks of all samples were located at 377.9 nm. However, there was some variation in the absorption spectra of the ZnO particles with different morphologies.

Polytechnic as a higher educational institution trains students to be capable of becoming independent human. It is also responsible for equipping students with competence to compete in the workplace. Sport serves as a means of character and life skills development in students. It is well supported by the infrastructure management in Polytechnic. Based on the formulation of the problem mentioned above, the general purpose of this study is to determine the effect of infrastructure management on sports development in the State Polytechnic of Bandung. This study employed quantitative approach with survey method to obtain data from questionnaires and physical fitness test. The participants of the study are 77 students from two state polytechnics in Bandung. The result from data processing and analysis showed that 95.7% of sports participation rate is influenced by infrastructure management and the rest of 4.35 is influenced by other unexplainable variables, which means that facility and infrastructure management give positive influence on sports participation. In addition, other results showed that 93.0% of physical fitness figures are influenced by infrastructure management and 7.0% is influenced by other unexplainable variable, which means that infrastructure gives significant influence on physical fitness. It shows that if sports infrastructure is managed well, then it will greatly influence sports development.

Abstract
We describe the CO Luminosity Density at High-z (COLDz) survey, the first spectral line deep field targeting CO(1–0) emission from galaxies at z = 1.95–2.85 and CO(2–1) at z = 4.91–6.70. The main goal of COLDz is to constrain the cosmic density of molecular gas at the peak epoch of cosmic star formation. By targeting both a wide (∼51 arcmin2) and a deep (∼9 arcmin2) area, the survey is designed to robustly constrain the bright end and the characteristic luminosity of the CO(1–0) luminosity function. An extensive analysis of the reliability of our line candidates and new techniques provide detailed completeness and statistical corrections as necessary to determine the best constraints to date on the CO luminosity function. Our blind search for CO(1–0) uniformly selects starbursts and massive main-sequence galaxies based on their cold molecular gas masses. Our search also detects CO(2–1) line emission from optically dark, dusty star-forming galaxies at z > 5. We find a range of spatial sizes for the CO-traced gas reservoirs up to ∼40 kpc, suggesting that spatially extended cold molecular gas reservoirs may be common in massive, gas-rich galaxies at z ∼ 2. Through CO line stacking, we constrain the gas mass fraction in previously known typical star-forming galaxies at z = 2–3. The stacked CO detection suggests lower molecular gas mass fractions than expected for massive main-sequence galaxies by a factor of ∼3–6. We find total CO line brightness at ∼34 GHz of 0.45 ± 0.2 μK, which constrains future line intensity mapping and CMB experiments.
Size Distributions of Solar Proton Events and Their Associated Soft X-Ray Flares: Application of the Maximum Likelihood Estimator
Authors: Cliver Edward W. , D’Huys Elke 
Published: August 2018

Abstract
We use the maximum likelihood estimator to determine the slope (α) of the power-law size distribution of the peak proton fluxes of a subsampled set of 106 ∼ 25 MeV solar energetic proton (SEP) events from 1997 to 2016 associated with western hemisphere soft X-ray (SXR) flares: α = 1.28 ± 0.03. For the peak SXR fluxes of a subsample of 110 SEP-associated flares, we find α = 1.51 ± 0.05. In addition, we obtained a slope of 1.61 ± 0.05 for the peak SXR fluxes of a sample of 128 ≥M1 SXR flares from 1996 to 2005 that were associated with coronal mass ejections (CMEs) with speeds ≥1000 km s−1. The slopes of both of these SXR peak-flux distributions (∼1.5 and ∼1.6) are closer to that for proton events (∼1.3) than to the α value of ∼2.1 (2.09 ± 0.08) determined for a subsample of 177 western hemisphere ≥M1 SXR flares considered from 1996 to 2005. These results are consistent with those of a previous study, based on a less reliable method (for small samples), in which it was argued that the flatter size distribution generally found for SEP events versus those for flare electromagnetic emissions was due to the fact that SEP flares are an energetic subset of all flares, characterized by their ∼100% association with fast/wide CMEs that drive coronal/interplanetary shock waves. Shock formation in the corona requires CMEs with speeds ≳400 km s−1, a threshold effect that further distinguishes SEP flares from the general population of all flares.

Abstract
We present detailed chemical abundances of three new bright (V ∼ 11), extremely metal-poor ([Fe/H] ∼ −3.0), r-process-enhanced halo red giants based on high-resolution, high-S/N Magellan/MIKE spectra. We measured abundances for 20–25 neutron-capture elements in each of our stars. J1432−4125 is among the most r-process-rich r-II stars, with [Eu/Fe] = +1.44 ± 0.11. J2005−3057 is an r-I star with [Eu/Fe] = +0.94 ± 0.07. J0858−0809 has [Eu/Fe] = +0.23 ± 0.05 and exhibits a carbon abundance corrected for an evolutionary status of [C/Fe]corr = +0.76, thus adding to the small number of known carbon-enhanced r-process stars. All three stars show remarkable agreement with the scaled solar r-process pattern for elements above Ba, consistent with enrichment of the birth gas cloud by a neutron star merger. The abundances for Sr, Y, and Zr, however, deviate from the scaled solar pattern. This indicates that more than one distinct r-process site might be responsible for the observed neutron-capture element abundance pattern. Thorium was detected in J1432−4125 and J2005−3057. Age estimates for J1432−4125 and J2005−3057 were adopted from one of two sets of initial production ratios each by assuming the stars are old. This yielded individual ages of 12 ± 6 Gyr and 10 ± 6 Gyr, respectively.

Abstract
We present the results from our Atacama Large Millimeter/submillimeter Array (ALMA) imaging observations of the CO(7−6), [C i] 370 μm (hereafter [C i]), and [N ii] 205 μm (hereafter [N ii]) lines and their underlying continuum emission of BRI 1335-0417, an infrared bright quasar at z = 4.407. At the achieved resolutions of ∼1.″1 to 1.″2 (or 7.5–8.2 kpc), the continuum at 205 and 372 μm (rest frame), the CO(7−6), and the [C i] emissions are at best barely resolved whereas the [N ii] emission is well resolved with a beam-deconvolved major axis of 1.″3(±0.″3) or 9(±2) kpc. As a warm dense gas tracer, the CO(7−6) emission shows a more compact spatial distribution and a significantly higher peak velocity dispersion than the other two lines that probe lower density gas, a picture favoring a merger-triggered star formation (SF) scenario over an orderly rotating SF disk. The CO(7−6) data also indicate a possible QSO-driven gas outflow that reaches a maximum line-of-sight velocity of 500–600 km s−1. The far-infrared (FIR) dust temperature (T
dust ) of 41.5 K from a graybody fit to the continuum agrees well with the average T
dust inferred from various line luminosity ratios. The resulting L
CO(7–6)/L
FIR luminosity ratio is consistent with that of local luminous infrared galaxies powered predominantly by SF. The L

Abstract
We present a detailed analysis of the kinematic properties of the multiple populations (MPs) in the low-mass Galactic globular cluster (GC) NGC 6362 based on a sample of about 500 member stars for which radial velocities (RVs), and Fe and Na abundances have been homogeneously derived. At distances from the cluster center larger than about 0.5r

h
, we find that first-generation (FG–Na-poor) and second-generation (SG–Na-rich) stars show hints of different line-of-sight velocity dispersion profiles, with FG stars being dynamically hotter. This is the first time that differences in the velocity dispersion of MPs are detected using only RVs. While kinematic differences between MPs in GCs are usually described in terms of anisotropy differences driven by the different radial distributions, this explanation hardly seems viable for NGC 6362, where SG and FG stars are spatially mixed. We demonstrate that the observed difference in the velocity dispersion profiles can be accounted for by the effect of binary stars. In fact, thanks to our multi-epoch RV measurements, we find that the binary fraction is significantly larger in the FG sample (f ∼ 14%) than in the SG population (f < 1%), and we show that such a difference can inflate the velocity dispersion of FG with respect to SG by the observed amount in the relevant radial range. Our results nicely match the predictions of state-of-the art N-body simulations of the co-evolution of MPs in GCs that include the effects of binaries.

Abstract
Studies comparing endogenous and recombinant serum amyloid A (SAA) have generated conflicting data on the proinflammatory function of these proteins. In exploring this discrepancy, we found that in contrast to commercially sourced recombinant human SAA1 (hSAA1) proteins produced in Escherichia coli, hSAA1 produced from eukaryotic cells did not promote proinflammatory cytokine production from human or mouse cells, induce Th17 differentiation, or stimulate TLR2. Proteomic analysis of E. coli–derived hSAA1 revealed the presence of numerous bacterial proteins, with several being reported or probable lipoproteins. Treatment of hSAA1 with lipoprotein lipase or addition of a lipopeptide to eukaryotic cell–derived hSAA1 inhibited or induced the production of TNF-α from macrophages, respectively. Our results suggest that a function of SAA is in the binding of TLR2-stimulating bacterial proteins, including lipoproteins, and demand that future studies of SAA employ a recombinant protein derived from eukaryotic cells.

Ship Scheduling in the Tramp Spot Market Based on Shipper's Choice Behavior and the Spatial and Temporal Shipping Demand
Authors: Zhao Yiran , Yang Zhongzhen 
Published: August 2018

Abstract
In the tramp spot shipping market, the choice of a shipper and the spatial and temporal shipping demand affect decisions regarding task choices and ship routing of the carrier. From the perspective of a carrier, this article divides the entire shipping planning horizon into a series of time windows and converts the carriers' market shares into shippers' choice inertia. Based on the spatial and temporal shipping demand, the obtained market shares in different time windows are analyzed, and the ship scheduling schemes, including the amount of shipped cargos, the sailing routes and the ships used, are determined with the objective of maximizing the carrier's profits. Finally, a numerical test is conducted using the Pacific tramp shipping market as an example.

Published: August 2018

Introduction:
This study investigated the association of graft-related surgical factors and patient characteristics with the odds of arthrofibrosis after primary anterior cruciate ligament reconstruction (ACL-R).

Methods:
A retrospective case-control study assessed consecutive patients who underwent primary ACL-R in one tertiary pediatric hospital. Each arthrofibrosis case was matched to three controls for sex, calendar year, and age at the time of ACL-R, as well as the primary surgeon. Conditional multivariable logistic regression assessed the independent association of graft diameter, time from injury to ACL-R, concomitant knee pathologies, and body mass index.

Results:
Twenty arthrofibrosis cases of 1,121 ACL-R patients (incidence 1.8%) were matched to 60 controls resulting in the mean age of 14.5 years. An increase of 1 mm graft diameter was associated with 3.2-times increased odds of arthrofibrosis. Other variables were not independently associated with arthrofibrosis.

Conclusion:
For young patients, the decision on the graft size must consider the possibility of arthrofibrosis with a larger graft versus reinjury with a smaller graft.

Published: August 2018

Com o presente estudo objetivou-se propor um protocolo para a avaliação do bem-estar de cães utilizados em atividades policiais, a partir de uma adaptação do protocolo Shelter Quality (SQ, Barnard et al., 2014), visando fornecer uma ferramenta para mensuração da qualidade de vida destes animais. Participaram do estudo 11 cães pertencentes ao canil do Pelotão de Policiamento com Cães da 4ª Cia PM Independente de Policiamento Especializado, Juiz de Fora, MG. O estudo foi dividido em: a) adaptação do protocolo SQ para avaliação do bem-estar dos cães; b) descrição da rotina de trabalho dos cães. Os indicadores de bem-estar presentes no protocolo SQ foram Organizados em três níveis de registro: medidas tomadas para o canil (tipo de alojamento, frequência de exercício, taxas de mortalidade e morbidade, manejo alimentar), medidas nos boxes (espaço disponível, tipo de cama, presença de superfície pontiaguda, fornecimento de água, conforto térmico e nível de latidos) e medidas obtidas nos animais, considerando cada indivíduo como uma unidade amostral (condição corporal, limpeza dos animais, condição do tegumento, claudicação, problemas respiratórios, evidência de dor, diarreia, comportamento anormal, reação ao ser humano e estados emocionais). Por tratar-se de uma pesquisa metodológica e descritiva, os dados foram analisados de modo predominantemente qualitativo. De acordo com os resultados, o protocolo SQ foi aplicável e ofereceu informações relevantes sobre o bem-estar dos cães. No entanto, o mesmo foi considerado incompleto, sendo necessária a inclusão de indicadores adicionais para que contemplasse um maior número de pontos críticos do bem-estar de cães de trabalho; são eles: manejo sanitário, transporte dos cães, higiene dos boxes, disponibilidade de enriquecimento ambiental, local de permanência dos cães durante a limpeza e manutenção dos boxes e socialização dos cães. Quanto à rotina dos cães, a carga horária de policiamento variou de 2 h a 10 h de trabalho semanal/animal, variando de 0 a 4 saídas semanais para policiamento, além de 0 a 160 minutos semanais de recreação fora dos boxes. Embora tenha sido elaborado para avaliação do bem-estar de cães de abrigo, o protocolo SQ foi exequível e prático para a avaliação de cães de trabalho militar. Foi necessário, porém, realizar algumas adaptações para sua melhor adequação às condições de canis militares.
