Oruta: Privacy-Preserving Public Auditing for Shared Data in the Cloud
With cloud data services, it is commonplace for data to be not only stored in the cloud, but also shared across multiple users. Unfortunately, the integrity of cloud data is subject to skepticism due to the existence of hardware/software failures and human errors. Several mechanisms have been designed to allow both data owners and public verifiers to efficiently audit cloud data integrity witho…

Perspectives on genetically modified crops and food detection
Genetically modified (GM) crops are a major product of the global food industry. From 1996 to 2014, 357 GM crops were approved and the global value of the GM crop market reached 35% of the global commercial seed market in 2014. However, the rapid growth of the GM crop-based industry has also created controversies in many regions, including the European Union, Egypt, and Taiwan. The effective d…

To better understand the elevational pattern of phylogenetic structure shown by alpine taxa and the underlying causes, we analyzed the phylogenetic structure of each elevational belt of alpine plants in the Hengduan Mountains Region, measured by net related index (NRI) and net nearest taxon index (NTI). We found both the indices of phylogenetic diversity indicated that alpine plants tended t…

Life stress and academic burnout
Stress has been shown to negatively affect learning. Academic burnout is a significant problem associated with poor academic performance. Although there has been increased attention on these two issues, literature on the relationship between students’ life stress and burnout is relatively limited. This study surveys academic burnout and life stresses among college students and further asse…

Abstract A non-close-packed three-dimensional photonic crystal of titania hollow spheres has been fabricated. The fabricated process is based on the silica template technique, thermal sintering, and the sol–gel process. The bandstructure calculations and optical measurements both indicate that a quasi-full three-dimensional photonic bandgap located at the visible wavelength has been presen…

Abstract. The atomic layer epitaxy (ALE) technique has been used to prepare uniform copper nanoparticles dispersed on a silica support (ALE-Cu/SiO2 with 2.85±0.32 nm), which are highly active in the water–gas shift reaction. Infrared spectra of CO adsorption are employed to study the active sites on ALE-Cu/SiO2 surface, suggesting that two major active sites are found on the copper surfa…

Abstract. A detailed kinetic model of NOx storage and reduction, in the presence of H2O and CO2, with hydrogen as the reducing agent was developed and validated in this study. The mechanism was derived from flow reactor experiments conducted at 200–400 ◦C over a Pt/Ba/Al monolith sample. The detailed kinetic model is divided into four sub-models: (i) NO oxidation over Pt, (ii) NOx stora…

Sorptive removal of tetracycline from water by palygorskite
Abstract. Extensive use of pharmaceuticals and growth hormone in farm animal and live stocks has resulted in their frequent detection in soils, groundwater, and wastewater. The fate and transport of these compounds are strongly affected by their sorptive behavior to the soil minerals and humic materials. In this research, we conducted the sorption of tetracycline (TC), a common antibiotic, …

Abstract. CaSn(OH)6 nanotubes were fabricated by sonochemical precipitation method at room temperature. A direct rolling process from nanosheets to nanotubes was expected for the synthesis of CaSn(OH)6 nanotubes. The transient CaSn(OH)6 nanosheets are formed as intermediates produced by the spontaneous self-assembly and transformation of amorphous colloid clusters. During the crystallizatio…

Abstract. Two representative rhamnolipidic fractions, RL-F1 and RL-F2, produced by the P. aeruginosa mutant strain MIG-N146, were separated and chemically characterized by TLC, HPLC-MS, and FTIR. The RL-F1 fraction is predominantly mono-rhamnolipid homologues with a high content of one or two fatty acid moieties. The RL-F2 fraction is mainly composed of di-rhamnosyl moieties with two hydrop…

Abstract. Bermudagrass, reed and rapeseed were pretreated with phosphoric acid–acetone and used for ethanol production by means of simultaneous saccharification and fermentation (SSF) with a batch and fed-batch mode. When the batch SSF experiments were conducted in a 3% low effective cellulose, about 16 g/L of ethanol were obtained after 96 h of fermentation. When batch SSF experiments we…

Abstract. Un-doped ZnO and MgZnO thin films were deposited on c-plane sapphire substrates by molecular-beam epitaxy (MBE) and subsequently annealed in hydrogen ambient at 200–500 oC with a step of 100 oC. Halleffect measurements show that annealing temperature has great effect on the electrical property of both ZnO and MgZnO films. The electron concentration of both ZnO and MgZnO films in…

Thermal activation and alkali dissolution of silicon from illite
Abstract. TGA, DTA, FTIR, XRD and 29Si MAS NMR were used to investigate the thermal activation of illite. Illite experiences a series of thermal solid-state phase transformations. Dehydroxylation at 400∼700 °C forms dehydrated illite, which remains the layered framework of illite. From 700 °C to 1093 °C, Si–O tetrahedral framework remains unchanged. When heated above 1093 °C, the layer…

Abstract Ce-promoted Ru/SBA-15 catalysts were prepared by a ‘‘two solvents’’ impregnation method. In liquidphase hydrogenation of benzene, the Ce-promoted Ru/SBA-15 catalysts exhibited superior catalytic performance to the un-promoted catalyst. The optimum bulk Ce/Ru molar ratio was determined to be 0.25, at which a cyclohexene yield of 53.8% was obtained. Based on characterizations…

Methane Cracking over a Bituminous Coal Char
Methane cracking over a bed of Chinese bituminous coal char was studied using a fixed-bed reactor at atmospheric pressure and temperatures between 1073 and 1223 K. Methane conversion over the fresh char increased with increasing temperature to 90% at 1223 K. Hydrogen was the only gas-phase product that was detected during the experimentation. The char was shown to exert a significant catalyt…

Preparation of Activated Ordered Mesoporous Carbons with a Channel Structure
CO2 activation on ordered mesopore carbon C-FDU-15. It is found that the continuous carbon framework of the precursor C-FDU-15 plays an important role in keeping the order structure of the resulting AOMCs-CS. The mild activation (e.g., 31 wt%burnoff) does not impair the order degree. After that, the order degree gradually decreases with further increasing burnoff. However, the basic hexagonal …

The performance of herbivorous insects is greatly affected by plant nutritional quality and resistance, which are likely to be altered by rising concentrations of atmospheric CO2. We previously reported that elevated CO2 enhanced biological nitrogen (N) fixation of Medicago truncatula, which could result in an increased supply of amino acids to the pea aphid (Acyrthosiphon pisum).
