Abstract Based on a novel triazine compound, the properties of tanned leather and commercial feasibility in pilot scale have been investigated. Then this novel approach tanning was compared with conventional chrome tanning: in the condition of less-salt pickling and chrome free, the physicochemical properties including thermal stability and mechanical strength were analyzed. Meanwhile, the surface roughness and fiber dispersion were evaluated as well. The results show that the thermal stability and mechanical strength of the triazine compound tanned leather are similar to conventional chrome tanned leather, the fiber bundle is well-dispersed and much evener than that More >

Abstract Haze-fog, which is an atmospheric aerosol caused by natural or man-made factors, seriously affects the physical and mental health of human beings. PM_2.5 (a particulate matter whose diameter is smaller than or equal to 2.5 microns) is the chief culprit causing aerosol. To forecast the condition of PM_2.5, this paper adopts the related the meteorological data and air pollutes data to predict the concentration of PM_2.5. Since the meteorological data and air pollutes data are typical time series data, it is reasonable to adopt a machine learning method called Single Hidden-Layer Long Short-Term Memory Neural Network (SSHL-LSTMNN)… More >

Abstract In the field of earthquake engineering, the advent of the performance-based design philosophy, together with the highly uncertain nature of earthquake ground excitations to structures, has brought probabilistic performance-based design to the forefront of seismic design. In order to design structures that explicitly satisfy probabilistic performance criteria, a probabilistic performance-based optimum seismic design (PPBOSD) framework is proposed in this paper by extending the state-of-the-art performance-based earthquake engineering (PBEE) methodology. PBEE is traditionally used for risk evaluation of existing or newly designed structural systems, thus referred to herein as forward PBEE analysis. In contrast, its use… More >

Abstract The use of magnesium alloys has been rapidly increased due to their ability to maintain high strengths at light weights. However weldability of steels and aluminum alloys by using resistance spot weld (RSW) process is a major issue, because it cannot be directly utilized for magnesium alloys. In this study, a structural-thermal-electrical finite element (FE) model has been developed to predict the distribution of residual stresses in RSW AZ61 magnesium alloy. Thermophysical and thermomechanical properties of AZ61 magnesium alloy have been experimentally determined, and have been used in FE model to increase the accuracy of… More >

Abstract This article discussed flow and temperature characteristics of the catalytic combustion furnace based the combustion of lean natural gas-air mixtures in catalytic honeycomb monoliths. Catalytic combustion as a developing technology could make the pollutant emissions (CO and NO_X) to near zero. Within the porous structure, the reactions then take place on the catalytic sites. A heterogeneous catalytic process includes more than one phase. Usually the catalyst is a solid and the reactants and products are in liquid or gaseous form. According to the applications of low- carbon catalytic combustion furnace, heating glazed tiles with pure solid More >

Abstract Plant functional traits and their effects on rangeland ecosystem function have received much attention by ecologists. However, the importance of functional traits and the interactive effects of grazing exclusion and climate are poorly understood. This study, therefore, aimed to analyse the response of Leymus chinensis functional traits in long-term grazing exclusion in different habitats (rainless typical steppe and rainy meadow steppe). This study showed that although the sensitivity and variability of different traits were similar in two steppe habitats, phenotypic plasticity of L. chinensis in meadow steppe was significantly higher than typical steppes. With the increased degree More >

Abstract Changes in root architecture are a strategy used by plants to explore the soil for available resources. The presence of beneficial microorganisms in the rhizosphere as well as plant growth regulators can cause changes in root development and promote the availability of water and nutrients. The effect of microorganisms or growth regulators on plant growth has been tested, but little is known about the effect they have on the architecture of the root of Hordeum vulgare L. Therefore the objective of this study was to evaluate the effect of the application of Rhizoglomus intraradices, Azospirillum brasilense, quercetin… More >

Abstract Pine-fruit shell (PFS) is a lignocellulosic residue derived from the fruit of Araucaria angustifolia, a coniferous tree native of South America, part of a whole vegetation of the Atlantic Forest, found in the South and Southwest of Brazil. In this work PFS will be characterized and used in the production of PFS-based polyols through oxypropylation. Three series were chosen (PFS/propylene oxide (PO) (w/v, g/mL) of 30/70, 20/80 and 10/90) with four catalyst levels (5%, 10%, 15% and 20%, (w/w, PFS based)). Oxypropylation occurred at moderate conditions of temperature, pressure and time giving rise to liquid… More >

Abstract A 73-year-old male with a remote history of renal cell carcinoma presented with an asymptomatic left ventricular mass. Biopsy of the mass revealed a late recurrence of his renal cell carcinoma. Given the size and location of the mass, resection was not possible. Treatment with pazopanib was initiated with good clinical response. More >

Abstract Antagonists of inhibitors of apoptosis proteins (IAPs), alone or in combination with genotoxic therapeutics, have been shown to efficiently induce cell death in various solid tumors. The IAP antagonist birinapant is currently being tested in phase II clinical trials. We herein aimed to investigate the antitumor efficacy of dacarbazine in vitro, both as a single agent and in combination with birinapant, in melanoma cell lines. Covering clinically relevant drug concentration ranges, we conducted a total of 5,400 measurements in a panel of 12 human melanoma cell lines representing different stages of disease progression. Surprisingly, functionally More >
