Opis:
The purpose of this study was to investigate the E-Commerce relationship quality and loyalty in B2B supplier and client’s relationships. This study tries to conceptualize a model based on the relationship quality that is applied to understand loyalty in B2B environment. The subjects of this study, from whom 81 valid questionnaires were collected, were the clients of the supplier’s ERP system in the Taiwan. When descriptive statistics and partial least squares (PLS) were adopted to analyse the collected valid data, we obtained the following findings. Relationship quality was perceived through the behavior of both supplier and clients and the quality of their interaction. Relationship quality antecedents include the information sharing and customer orientation. The finding suggests that supplier with strong levels of customer orientation, the supplier and clients were built a stronger relationship and high loyalty. Surprisingly, information sharing shown no significant effects on the relationship quality. This study implies that using information sharing and customer orientation strengthen their relationship quality, thereby enhancing loyalty. The finding of this study implies that it is important for a B2B supplier management to understand clients’ needs and responses. B2B suppliers can learn from this study, that customer orientation, relationship quality, commitment, have a positive impact on loyalty in both direct and indirect ways.
Celem artykułu była analiza jakości relacji z klientami i lojalności w handlu elektronicznym u dostawcy B2B. Niniejsze badanie jest próbą konceptualizacji modelu opartego na jakości relacji, który jest próbą zrozumienia lojalności w środowisku B2B. Przedmiotem badania byli wybrani klienci systemu ERP w oparciu na zebranych 81 kwestionariuszach firm na Tajwanie. Przyjęto statystyki opisowe i w oparciu o metodę najmniejszych kwadratów (PLS) w celu przeanalizowania zebranych istotnych danych. Jakość relacji postrzegano poprzez zachowanie zarówno dostawcy, jak i klientów oraz jakość ich interakcji. Jakość relacji przede wszystkim obejmuje dzielenie się informacjami i orientację na klienta. Wyniki sugerują, że dostawcy z silnym poziomem orientacji na klienta, zbudowali silniejszą więź i wysoką lojalność relacji z dostawcami i klientami. Co zaskakujące, wymiana informacji nie wykazała znaczącego wpływu na jakość relacji. Badanie zakłada, że korzystanie z wymiany informacji i orientacja na klienta wzmacnia ich jakość relacji, zwiększając przez to lojalność. Odkrycie tego badania implikuje, że dla dostawcy usług B2B ważne jest zrozumienie potrzeb i odpowiedzi klientów. Dostawcy B2B winni zauważyć, że orientacja na klienta, jakość relacji, zaangażowanie, mają pozytywny wpływ na lojalność zarówno w sposób bezpośredni, jak i pośredni.

Opis:
We comparatively studied the ball mill grinding characteristics of comminuted hematite products using a high-pressure grinding roll (HPGR) and a conventional cone crusher (CC). The major properties, including grinding kinetics and technical efficiency (Et), were investigated. The parameters in m-th order grinding kinetics were analyzed, and grinding specific rates were visualized. Ore particles experienced three inherent stages in ball grinding mills, that is i) rapid grinding of coarse fraction, ii) dynamic grinding of medium size fraction, and iii) single grinding of medium size fraction. Particles with size -0.043+0.031 mm were used into dynamic grinding stage earlier than particles -0.105+0.043 mm, and then over-grinding of fines occurred easily. Compared with CC products, HPGR products had significantly shorter turning time points in three breakage stages, implying that HPGR products were ground faster with earlier occurrence of fines over-grinding. HPGR products gave lower Et at a decreasing rate than the CC products for -2.0 mm and -0.5 mm feeds. Then, it showed a slightly higher value of Et for -2.0+0.5 mm feed. This indicated that fines over-grinding in HPGR full-size products were more serious under the condition of coarse grinding, whereas the efficiency was higher, and over-grinding weakened significantly in HPGR coarse products because of screening-out fines.

Opis:
Thermal behavior and microstructure of $Fe_{81 - x}Co_{x}Zr_7Nb_2B_{10}$ (x = 2, 4, 6) alloys were investigated by differential thermal analysis and X-ray diffraction. Both the supercooled liguid region Δ $T_{x}$ and the first crystallization peak temperature $T_{p1}$ are the lowest and the span Δ $T_{p}$ between $T_{p1}$ and $T_{p2}$ is the highest when 4 at.% Fe is substituted by Co. The crystallization activation energy $E_{p1}$ for $Fe_{75}Co_6Zr_7Nb_2B_{10}$ alloy is the minimum for the heating rates ν = 5-20 K/min. $E_{p1}$ for $Fe_{77}Co_4Zr_7Nb_2B_{10}$ alloy is the minimum for the heating rates ν = 20 - 50 K/min. The crystallization processes of $Fe_{81 - x}Co_{x}Zr_7Nb_2B_{10}$ (x = 2, 4, 6) amorphous alloys are similar on the whole, which is as follows: amorphous → amorphous + α-Fe(Co) → α-Fe(Co) + $Fe_3Zr$ + $Fe_2Nb_{0.4}Zr_{0.6}$.

Opis:
A FEM-BEM coupling approach is used for acoustic fluid-structure interaction analysis. The FEM is used to model the structure and the BEM is used to model the exterior acoustic domain. The aim of this work is to improve the computational efficiency and accuracy of the conventional FEM-BEM coupling approach. The fast multipole method (FMM) is applied to accelerating the matrix-vector products in BEM. The Burton-Miller formulation is used to overcome the fictitious eigen-frequency problem when using a single Helmholtz boundary integral equation for exterior acoustic problems. The continuous higher order boundary elements and discontinuous higher order boundary elements for 2D problem are developed in this work to achieve higher accuracy in the coupling analysis. The performance for coupled element types is compared via a simple example with analytical solution, and the optimal element type is obtained. Numerical examples are presented to show the relative errors of different coupled element types.

Opis:
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.

Opis:
In order to effectively extract and maximize the energy from ocean waves, a new kind of oscillating-body WEC (wave energy converter) with moon pool has been put forward. The main emphasis in this paper is placed on inserting the damping into the equation of heaving motion applied for a complex wave energy converter and expressions for velocity potential added mass, damping coefficients associated with exciting forces were derived by using eigenfunction expansion matching method. By using surface-wave hydrodynamics, the exact theoretical conditions were solved to allow the maximum energy to be absorbed from regular waves. To optimize the ability of the wave energy conversion, oscillating system models under different radius-ratios are calculated and comparatively analyzed. Numerical calculations indicated that the capture width reaches the maximum in the vicinity of the natural frequency and the new kind of oscillating-body WEC has a positive ability of wave energy conversion.

Opis:
High carbon ferromanganese is used as a starting material to prepare pure ferromanganese by electrorefining in molten salts. High carbon ferromanganese was applied as the anode, molybdenum was the cathode and Ag/AgCl was the reference electrode. The anodic dissolution was investigated by linear polarization in molten NaCl-KCl system. Then potentiostatic electrolysis was carried out to produce pure ferromanganese from high carbon ferromanganese. The cathodic product was determined to be a mixture of manganese and iron by x-ray diffraction (XRD). The content of carbon in the product was analyzed by carbon and sulfur analyzer. The post-electrolysis anode was characterized by scanning electron microscope (SEM). The mechanism of the anode dissolution and the distribution of the main impurity of carbon and silicon after electrolysis were discussed.

Opis:
Toluene mono-nitration in a semi-batch reactor was investigated with reaction calorimeter (RC1). The mixed acid HNO3/H2SO4/H2O (wt%) was used in proportion 13/66/21, which is similar to industrial parameters. The exothermic rates at different reaction temperatures were compared, and then the curves of heat generation rate after dosing were analyzed. The Maximal Temperature attainable by runaway of the desired Synthetic Reaction (MTSR) under different conditions were calculated for the course hazard evaluation. The results showed that the average reaction heat of mono-nitration was between 169.07~177.11 kJ mol-1, and the special heat of reactant was about 2 kJ kg-1 K-1. Average Ea of second order kinetic was about 30 kJ mol-1, and reaction rate was 10-4 mol s-1 l-1 order of magnitude when the strength of sulphuric acid was about 73.5%. It was also found that when temperature or stirring speed increases, the potential heat accumulation decreases.
