Opis:
Investigations into Muslim psychology sometimes rely on measures emphasizing religious attitudes, with the Muslim Attitudes toward Religion (MAR) scale being an example. To capture the experiential aspects of Islamic religiosity, a recently developed Muslim Experiential Religiousness (MER) scale recorded an experienced submission to, love of, and closeness to God that define an ideal in Muslim religious consciousness. In a sample of 299 students from the University of Tehran and the Qom Islamic Seminary School, this study administered the MAR and MER, along with scales assessing mysticism, religious orientations, depression, anxiety, and satisfaction with life. Results demonstrated incremental validity of the MER over the MAR in predicting most of these religious and psychological adjustment variables. The MER also mediated and moderated some MAR relationships with religious and psychological outcomes. These data pointed toward a dissociation of the attitudinal and experiential features of Muslim psychology and confirmed the MER as a valuable index of Muslim religious experience.

Opis:
In order to reveal the seepage law of ammonium carboxylate solution in the in-situ leaching process of weathered crust elution-deposited rare earth ores, the effects of concentration, pH, temperature, particle size and porosity on permeability were discussed in this paper. The results shown that the seepage of the leaching agent solutions in the rare earth ore follows Darcy's law and displays a laminar flow under the conditions of this experiment and seepage velocity can be increased by changing leaching conditions. The permeability coefficients are inversely proportional to concentrations of ammonium acetate, ammonium tartrate and ammonium citrate whose concentration is greater than 0.7wt%, because the insoluble complexes formed by the reaction of ammonium citrate with RE3+ at lower concentration n decrease the permeability coefficient. The permeability coefficients of ammonium carboxylate solutions increase firstly and then decrease with the pH increased. The maximum of permeability coefficients of ammonium acetate, ammonium tartrate and ammonium citrate solution were 2.92, 1.91 and 2.70, respectively, while the pH of solution were 5, 6 and 7, respectively. Increasing temperature is beneficial for the seepage of ammonium carboxylate solution in orebody, therefore, it is helpful for leaching operation in summer. Moreover, clay minerals particle size and porosity are the key factors affecting the permeability of ammonium carboxylate solution in orebody. The permeability coefficients of ammonium acetate, ammonium tartrate and ammonium citrate solutions are 2.92×104cm/s,1.90×10-4cm/s and 2.69×10-4cm/s, respectively, at the same temperature of 293K, original particle size and porosity of the ore. Ammonium acetate solution has the best permeability in orebody.

Opis:
To improve the leaching process of rare earth and reduce the impurities in the leachate, the carboxylate ammonium, such as ammonium acetate, ammonium citrate and ammonium tartrate, were selected as lixiviant to compare the effects of concentration, flow rate, pH and temperature on leaching mass process of rare earth and aluminum. Meanwhile, the leaching behaviors of rare earth and aluminum leached by three kinds of carboxylate ammonium were analyzed by chromatographic plate theory. The relationship between the flow rate and height equivalent (HETP) could fit well with the Van Deemter equation and there was an optimal flow rate (uopt) for the leaching of the rare earth and aluminum. Besides, the conditions of carboxylate ammonium lixiviant were optimized. The optimum concentrations of ammonium acetate, ammonium tartrate and ammonium citrate were 15 g/L, 25 g/L and 5 g/L respectively, the leaching flow rate was 0.50 mL/min, the pH value was approximatively 7.00 and the leaching temperature was 293 K to 303 K. At these conditions, the mass transfer efficiencies of three ammonium carboxylates for rare earth and aluminum was in the order of ammonium acetate > ammonium tartrate > ammonium citrate. Moreover, the ammonium acetate could commendably inhibit aluminum ions entering the lixivium.

Opis:
The morphology and morphogenesis of the hypotrich ciliate Urosoma macrostyla (Wrześniowski, 1866) Berger, 1999, collected from a puddle in Harbin, China, were investigated using live observation and protargol impregnation. Based on previous and present studies, an improved diagnosis of U. macrostyla is supplied. It differs from its congeners mainly by the body shape, no cortical granules and number of macronuclear nodules. The ontogenesis of U. macrostyla is typical for species with such a somatic ciliary pattern: the oral primordium develops hypoapokinetally and FVT-anlagen develop in 5-streaks and primary mode. However, a unique characteristic in morphogenetic process is reported: anlagen for both the left and right marginal cirri occur de novo to the right of the parental structure which has never been seen in other oxytrichids. This characteristic was considered an apomorphy (Berger 1999). This indicates that U. macrostyla possibly has a high phylogenetic position within the genus Urosoma, or perhaps it represents a distinct subgenus.

Opis:
In this paper, we propose a multi-layer micro-perforated panel structure based on a curled space for broadband sound absorption at low frequencies, which increases the number of perforated panel layers in a limited space using a curled space. The absorption coefficients of the structure under plane wave conditions were calculated using the transfer matrix method and the finite element method. It is demonstrated that the multilayer micro-perforated panel structure can ensure high absorption (consistently over 90%) in the frequency range of 400~5000 Hz. The sound absorption mechanism of the multi-layer micro-perforated panel structure is investigated by using the acoustic impedance along with the reflection coefficient of the complex frequency surface. In addition, we also discuss the effects of the micro-perforated panel parameters on the structural sound absorption coefficient. The results show that the proposed multi-layer micro-perforated panel structure provides an excellent solution for sound absorption in a limited space.
