Stem growth habit is an important agronomic trait in soybean and is subject to artificial selection. This study aimed to provide a theory for genotypic selection of stem growth habit for breeding purposes by analyzing the alleles of GmTfl1 gene in Chinese soybean varieties and establishing a database of GmTfl1 variation. Using knowledge of insertion and deletion (Indel) in the non-coding regio…
This paper considers fault-tolerant control that ensures the safety of a discrete-event system. We consider multiple faulty modes. Each faulty mode is modeled by an automaton. These automata, together with the automaton modeling normal mode, describe a discrete-event system with faults. Each faulty mode has some illegal states that must be avoided by control so that the fault can be tolerated. …
Regulation of Myc protein abundance is critical for normal cell growth as evidenced by the fact that deregulated Myc expression is a hallmark of many cancers. One of several important mechanisms that control Myc levels involves its phosphorylation-dependent proteolysis. Previous studies have shown that phosphorylation of threonine 58 by glycogen synthase kinase 3β (GSK3β) within the conserved…
Abstract. The deposition of corrosion products of MmNi3.55Co0.75Al0.2Mn0.5 alloy in the positive electrodes of nickel-metal-hydride (Ni-MH) battery is tested by using inductively coupled plasma spectroscopy. The deposition amounts of Al and Mn are markedly reduced by using an acrylic acid (AA) grafted polypropylene (PP) separator. The detrimental effect of Mn on self-discharge performance …
Social desirability responding (SDR) was affected by situation and age. However, most research is only concerned with overall SDR without considering the separation of impression management and self-deception. The purpose of this article is to explore the possible different effects of age and situation on the different components of SDR. A total of 158 teachers completed the BIDR at a 2 (high v…
Abstract. A graphene–C60 hybrid material has been synthesized using a chemical coupling method between graphene oxide and pyrrolidine fullerene. The formation of this hybrid material was verified by Fourier transform infrared spectroscopy, thermal gravimetric analysis and high-resolution transmission electron microscopy. Raman spectroscopy suggests a strong interaction between the C60 cage a…
Abstract. The current–voltage characteristics of individual cup-stacked carbon nanotubes (CSCNTs) were investigated in situ inside the transmission electron microscope. Different from other quasi-1D carbon structures such as multi-walled carbon nanotubes, carbon nanofibers or graphitic fibers that normally behave as a metallic conductor of electrons, individual CSCNTs were found to exhib…
Abstract. Composites based on graphene-based sheets have been fabricated by incorporating solution- processable functionalized graphene into an epoxy matrix, and their electromagnetic interference (EMI) shielding studies were studied. The composites show a low percolation threshold of 0.52 vol.%. EMI shielding effectiveness was tested over a frequency range of 8.2–12.4 GHz (X-band), and …
Abstract. To explore the effects of the novel properties of carbon nanoparticles (CNPs) on cytotoxicity, the adsorption of serum proteins in cell culture medium on multi-walled carbon nanotubes and three kinds of carbon blacks was investigated. The uptake of CNPs by Hela cells was measured quantitatively using 99mTc radionuclide labeling and tracing techniques, and the dependence of CNPs u…
Abstract. Ni-, Cu-, and Fe-loaded acidic and basic Y zeolites were synthesized, and their catalytic properties for oxidative dehydrogenation of ethane (ODHE) to ethylene were characterized. Acidic Ni-loaded Y zeolite exhibits an ethylene productivity of up to 1:08 gC2H4 gcat-1 h-1 with a selectivity of 75%. Acidic Cu- and Fe-loaded Y zeolites have an ethylene productivity of up to 0:37 gC…
Abstract. Three methods were investigated to synthesize mesoporous mordenite. XRD, N2 physisorption, SEM, and TEM showed that the mordenite obtained by acid leaching followed by base leaching of a conventional mordenite is a crystalline mesoporous material with MOR framework. The higher diffusivity of toluene indicated that mesopores benefited molecule transport through the zeolite crystal.…
Abstract. Selective catalytic reduction of NO with acetylene (C2H2-SCR) over mordenite-based catalysts (HMOR, 0.5% Mo/HMOR and NaMOR) was investigated by in situ Fourier transform infrared spectroscopy. A possible mechanism was proposed to explain catalytic performance of the mordenite-based catalysts in the C2H2-SCR: Nitrosonium ions (NO+) and bidentate nitrate are reactive nitric species …
Abstract. Nitrogen doped mesoporous TiO2 was prepared via a modified two-step hydrothermal route. In contrast to undoped mesoporous TiO2, nitrogen doped mesoporous TiO2 has superior photocatalytic activity under both UV and visible light irradiation. Photoluminescence spectra reveal that nitrogen doped mesoporous TiO2 possesses abundant surface states, which can play a vital role in trappin…
Abstract. To improve the dissolution rate of ibuprofen, a model poorly water soluble drug, self-nanoemulsifying drug delivery systems (SNEDDS) were developed. Various surfactants and oils were screened as candidates for SNEDDS on the basis of droplet size of the resulting emulsions. The influence of the constituent structure, concentration and the composition of SNEDDS formulations, and the…
Abstract. ZnO nanorod arrays on ZnO-coated seed layers were fabricated by aqueous solution method using zinc nitrate and hexamethylenetetramine at low temperature. The seed layers were coated on ITO substrates by electrochemical deposition technique, and their textures were dominated by controlling the deposition parameters, such as deposition potential and electrolyte concentration. The ef…
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…
Abstract. Carbon nanotubes have been prepared via catalytic chemical vapor deposition of acetylene on a series of catalysts derived from Co/Fe/Al layered double hydroxides (LDHs). The catalytically active cobalt particles were obtained by calcination of LDHs containing cobalt (II) ions followed by reduction. The obtained products were characterized by X-ray diffraction, X-ray photoelectron …
Extraordinary and stable long wavelength emission centered at 685 nm from the yard-glass shaped boron nitride nanotubes YG-BNNTs was observed in their cathodoluminescence and photoluminescence spectroscopy. The mechanism for this near-red light emission at 685 nm is attributed to the periodical nature of the BNNT units with regular lattice defects. The visible-light emission from YG-B…
Using anionic surfactant as templates, ordered mesoporous silica hollow spheres (MSHSs) with radially oriented mesochannels were synthesized with the aid of ultrasonic irradiation. The product was consisted of intact and dispersed hollow spheres with the diameter mostly in the range of 100-500 nm. The hollow spheres possessed uniform shell with the thickness of 35-40 nm, and the shell with r…
High temperature stress disturbs cellular homoeostasis and results in a severe retardation in crop growth and development. Thus, it is important to reveal the mechanism of plants coping with heat stress. In this study, a novel gene that we identified from Brassica napus, referred to as BnTR1, was found to play a key role in heat stress response in planta. BnTR1 is a membranebound RINGv (C4H…
