Opis:
The diffusion mechanisms of lithium ions in tetragonal phase as well as in Al and Nb stabilized cubic Li7La3Zr2O12 compounds were investigated by low-frequency internal friction technique. In the cubic Li7La3Zr2O12 phase, a remarkable relaxation-type internal friction peak PC with a peak height up to 0.12 was observed in the temperature range from 15°C to 60°C. In the tetragonal phase however, the height of the PT peak dropped to 0.01. The obvious difference of the relaxation strength between the cubic and tetragonal phases is due to the different distribution of lithium ions in lattice, ordered in the tetragonal phase and disordered in the cubic phase. Based on the crystalline structure of the cubic garnet-type Li7La3Zr2O12 compound, it is suggested that the high internal friction peak in the cubic phase may be attributed to two diffusion processes of lithium ions: 96h↔96h and 96h↔24d.

Opis:
We study the contribution of variable surface effects to the antiplane deformation of a linearly elastic material with a mode-III crack. The surface elasticity is incorporated using a modified version of the continuum based surface/interface model of Gurtin and Murdoch. In our discussion, the surface moduli are not constant but vary along the crack surfaces. Using Green’s function method, the problem is reduced to a single first-order Cauchy singular integro-differential equation, which is solved numerically using Chebyshev polynomials and a collocation method. Our results indicate that the gradient of the surface shear modulus exerts a significant influence on the crack opening displacement and on the singular stress field at the crack tips.

Opis:
Novel water gel explosives containing expired single base and double base propellant grains were prepared by using a new gelling agent and a simple process. The shock wave overpressures and underwater output energies of the explosives were measured. The detonation performances of the explosives were also investigated. As the particle size of the propellant was increased, the detonation velocity, peak overpressure and underwater energy of the explosive containing single base propellant (NCP) were gradually reduced. Double base propellant (DBP) had low detonation sensitivity due to its thermoplasticity. When it was mixed with the appropriate quantity of NCP, DBP could also be reused. NCP acted as the sensitizer and energy source in the explosive containing both DBP and NCP. So the detonation velocity, peak overpressure and underwater energy of the explosive increased with the increase in ωNCP. With excellent detonation performance, these two kinds of water gel explosives can be used as opencast blasting agents.

Opis:
In the B10 isotope enrichment industry, the purification of anisole mixture makes great sense. A dynamic-accumulative operation policy of continuous distillation (DACD) with repeated filling and dumping of the still is proposed for the separation of trace heavy impurities in the recycled anisole. To simulate and optimize the purification process of anisole, a mathematical model of DACD is derived, and the computer codes are developed in the MATLAB environment. Moreover, the experiment is performed in a pilot-scale distillation column. The results show that the experimental date agrees well with simulation results. DACD could solve the difficulty of flow rate control when the bottom flow rate is very small in continuous distillation. The size of the still in this operation mode is also smaller than that in batch distillation. And the yield of anisole is raised to 99.91%. In a word, DACD is especially suitable for separating trace heavy impurities from the recycled anisole.

Opis:
A multi-ship collision avoidance decision-making and path planning formulation is studied in a distributed way. This paper proposes a complete set of solutions for multi-ship collision avoidance in intelligent navigation, by using a top-to-bottom organization to structure the system. The system is designed with two layers: the collision avoidance decision-making and the path planning. Under the general requirements of the International Regulations for Preventing Collisions at Sea (COLREGs), the performance of distributed path planning decision-making for anti-collision is analyzed for both give-way and stand-on ships situations, including the emergency actions taken by the stand-on ship in case of the give-way ship’s fault of collision avoidance measures. The Artificial Potential Field method(APF) is used for the path planning in details. The developed APF method combined with the model of ship domain takes the target ships’ speed and course in-to account, so that it can judge the moving characteristics of obstacles more accurately. Simulation results indicate that the system proposed can work effectiveness.

Opis:
Along with the advancement of manufacturing techniques, the quality of the spares for product is likely to be improved during the warranty period. There can be two types of spares, i.e. low-quality spares and high-quality spares for replacement maintenance. And the manufacturers (customers) may have to decide whether or not to provide (buy) the warranty considering upgrading maintenance. This paper presents a renewing warranty policy considering three maintenance options for products with multiple failure modes. The cost and availability models of these maintenance options are proposed. Of these options, upgrading maintenance is taken into account with the assumption that the warrantied item will be upgraded one time during the warranty cycle. After upgrading maintenance, the high-quality spares are used to replace the failed item. By minimizing the ratio between cost and availability of the product, the optimal upgrading opportunity is obtained. In the numerical example, the results of these options are presented. Monte Carlo simulation results are compared with the analytical results to demonstrate the correctness and efficiency of the proposed models considering upgrading maintenance. The renewing warranty policy considering upgrading maintenance policy is compared with the one without considering upgrading maintenance. The results show that the former is better than the latter in some cases. The sensitivity of the cost model and availability model to different parameters is analyzed at last.
Wraz z postępem techniki produkcji, wzrasta prawdopodobieństwo, że jakość części zamiennych do produktu ulegnie poprawie w przeciągu okresu gwarancyjnego. Istnieją dwa rodzaje części zamiennych: części zamienne niskiej i wysokiej jakości. Producenci (klienci) mogą być zmuszeni podjąć decyzję czy objąć produkt gwarancją (wykupić gwarancję) zapewniającą konserwację modernizacyjną. W artykule przedstawiono politykę odnawiania gwarancji z uwzględnieniem trzech różnych opcji obsługi produktów narażonych na mnogie przyczyny uszkodzeń. Zaproponowano modele kosztów i gotowości dla omawianych opcji obsługi. Spośród badanych opcji, do dalszej analizy wybrano konserwację modernizacyjną zakładającą, że element podlegający gwarancji zostanie poddany jednokrotnej modernizacji podczas cyklu gwarancyjnego. Po wykonaniu konserwacji modernizacyjnej, uszkodzony element zastępuje się częściami zamiennymi wysokiej jakości. Minimalizując stosunek kosztów do gotowości produktu, uzyskuje się optymalną możliwość modernizacji Przykład numeryczny przedstawia wyniki uzyskane dla omawianych opcji. Wyniki symulacji Monte Carlo porównano z wynikami analitycznymi w celu wykazania prawidłowości i efektywności proponowanych modeli uwzględniających konserwację modernizacyjną. Politykę odnawiania gwarancji uwzględniającą konserwację modernizacyjną porównano z polityką, która takiej konserwacji nie uwzględnia. Wyniki pokazują, że pierwsza z tych opcji jest w niektórych przypadkach korzystniejsza od drugiej. Badania wieńczy analiza czułości modelu kosztów i modelu gotowości na różne parametry.

Hydrogen sulfide (H2S) is an important signaling molecule involved in several stress-resistance processes in plants, such as drought and heavy metal stresses. However, little is known about the roles of H2S in responses to chilling stress. In this paper, we demonstrated that chilling stress enhance the H2S levels, the H2S synthetase (L-/D-cysteine desulfhydrase, L/DCD) activities, and the expression of L/DCD gene in Vitis vinifera L. ‘F-242’. Furthermore, the seedlings were treated with sodium hydrosulfide (NaHS, a H2S donor) and hypotaurine (HT, a H2S scavenger) at 4°C to examine the effects of exogenous H2S on grape. The results revealed that the high activity of superoxide dismutase and enhanced expression of VvICE1 and VvCBF3 genes, but low level of superoxide anion radical, malondialdehyde content and cell membrane permeability were detected after addition of NaHS. In contrast, HT treatment displayed contrary effect under the chilling temperature. Taken together, these data suggested that H2S might be directly involved in the cold signal transduction pathway of grape.

Four complexes with the formula of [M5(DATr)12~14(H2O)6](ClO4)10 (M = Mn (1), Co (2), Ni (3), Zn (4)) about their synthesis, structures and some energetic properties (such as sensitivities tests) have been described, where the DATr here denotes 3,4-diamino-1,2,4-triazole. These four compounds are all light metallic complexes with good thermal stability. The structures of 2-4 were determined by single-crystal X-ray diffraction, and the crystal structures mainly consist of penta-nuclear units. All the structures have a common interesting property in which DATr plays a role of bi-dentate ligand. Besides, it is observed from the crystal structure of 4 that DATr can be also act as a mono-dentate ligand. Thermodynamic studies of their decomposition properties and kinetic parameters show that the four complexes have high thermal stabilities. Furthermore, tests of their impact and friction sensitivities show that complexes (2) and (3) can be potential candidates as primary explosives to replace toxic lead azide.

Opis:
The adsorption of pentafl uorobenzene on nine ionic liquid-based silicas was investigated using solid phase extraction. The effects of several variables such as the type of ionic liquid groups, adsorption time, temperatures and water ratio in the solution system were experimentally evaluated. The imidazole-chloride ionic liquid group based silica exhibited the highest adsorption efficiency under the optimized conditions of 5 min adsorption at 30°C in water/methanol (30:70, vol%) solution. In addition, the effects of pH, as well as type and concentrations of chloride salts were investigated. At pH values other than neutral and high salt concentration, the adsorption efficiency was reduced. Finally, the relative standard deviation of less than 5.8% over a 5-day period showed a high precision for the nine tested sorbents.

Opis:
A polarization photonic crystal fiber based on surface plasmon resonance is proposed in this paper. The photonic crystal fiber with gold coated holes is studied through using the finite element method. The impacts of structural parameters on the resonance characteristics are discussed. Numerical simulations show that the resonance wavelength can be modulated by changing the parameters of the air holes and thickness of gold layer. At the resonance wavelength 1550 nm, the loss is 3.8045 dB/m in x-polarization and the loss is 28464 dB/m in y-polarization by adjusting the size of the gold-coated holes and the place of air holes. Results show that the loss of y-polarized mode is much larger than the loss of x-polarized mode. The y-polarized mode is suppressed, and only x-polarized mode can be guided at the resonance wavelength of y-polarized mode. The results indicate that the mode polarized in one direction can be filtered out selectively by adjusting the diameter of air holes, and the filtering effect in a communication band is achieved.

Opis:
In order to simplify the optical setup and the encryption process, a diffractive-imaging-based optical encryption system using a single diffraction pattern is proposed. A predesigned binary mask is placed before the plaintext in the encryption process, and three randomly distributed phase only masks are placed in the optical path. Only one diffraction pattern needs to be recorded as ciphertext by CCD. In the decryption process, an iterative phase retrieval algorithm is applied, in which the predesigned binary mask acts as a support constraint in the input plane. After the iterative process, an interpolation operation for the zero-valued pixels is also implemented. The effectiveness and robustness of the proposal are demonstrated by numerical simulation results.

Opis:
Cellulase has the ability to remove fuzz-fibres from cellulosic textiles, which endows fabric with a glabrous appearance and soft handle. In this paper, the combined uses of bio-polishing and reactive dyeing in one bath were carried out, aiming at shortening the treatment time and reducing the overall consumption of water and energy as well. The properties of cotton fabrics before and after the combined treatments were investigated, including the colour strength, colour fastnesses and tearing strength. The results indicated that the colour fixing agent of soda had noticeable inhibiting effects on cellulase activity. Meanwhile reactive dyes might react with cellulase proteins under alkaline conditions, resulting in decelerating influences on the dye-fibre covalent reactions. The acceptable one-bath process consisted of bio-polishing and dyeing of cotton in neutral solution, followed by dye fixation under alkaline conditions. Compared to polishing and dyeing in two baths, the one-bath method endowed fabric with a bit lower colour strength.
Celulaza ma zdolność do usuwania włosków zmechacenia z tekstyliów celulozowych, co pozwala na osiągnięcie gładkiej powierzchni o delikatnym chwycie. W pracy badano sumaryczny efekt biopolerowania i reaktywnego barwienia przeprowadzanych w jednej kąpieli. Metoda ta ma na celu skrócenie czasu obróbki i zredukowanie ogólnego zapotrzebowania na wodę i energię. Badano właściwości tkanin bawełnianych przed i po obróbce. Między innymi badano nasycenie kolorem, trwałość koloru i wytrzymałość na rozrywanie. Wyniki wskazują, że soda jako środek utrwalający kolor ma zauważalny wpływ na hamowanie działania celulazy. Porównując metodę równoczesnego polerowania i barwienia z metodą, gdzie obydwie obróbki stosowane są indywidualnie stwierdzono, że w metodzie równoczesnej obróbki uzyskuje się nieco niższe nasycenie koloru.

Opis:
In this assay, we developed and evaluated a multiplex PCR (mPCR) for its ability in detecting multiple infections of swine simultaneously. Four pairs of primers were used to detect five viruses. Specific primers were designed for classical swine fever virus (CSFV), African swine fever virus (ASFV) and pseudorabies (PRV). A pair of primers was designed prudently for two different types of porcine reproductive and respiratory syndrome virus that respectively were porcine reproductive and respiratory syndrome virus (PRRSV), highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV). The detection limits of the mPCR were 1.09×10⁴, 1.50×10³, 2.10×10³, 1.30×10³ and 8.97×10² copies/reaction for CSFV, ASFV, HP-PRRSV, PRRSV and PRV, respectively. A total of 49 clinical specimens were tested by the mPCR, and the result showed that co-infection by two or three viruses was 51%. In conclusion, the PCR is a useful tool for clinical diagnosis of not only single infections but also mixed infections in swines.
