Abstract:

This study investigated an expert pianist's nine-month preparation for a public music performance (recital) through the collection of practice diaries and MIDI recordings of the eight scheduled pieces. Recordings were made under the experimentally varied conditions of solitary performance and public performance. The practice diaries revealed that the expert (an advanced student performer) allocated practice time consistently across the entire preparation period and tended to use mornings to practice the pieces perceived as being more difficult. Total preparation time for each of the pieces could be predicted on the basis of the pianist's subjective ratings of complexity and independent ratings of complexity given by other experts. An analysis of the performance data showed that, near the time of the recital, variability in performance tempo was large between pieces but very small for multiple renditions of the same piece, even under the different experimental conditions. Thus, to attain a highly reproducible public performance, the expert allocated practice time in response to task demands and engaged in specific preparations that would safeguard the performance against unexpected problems.

Abstract:

Abstract Six different procedures for radioiodination of mouse epidermal growth factor (EGF) all resulted in a heterogeneous 125I-labeled EGF preparation, as analyzed by reversed-phase HPLC. EGF preparations that had been iodinated with Chloramine T, lodogen, or lodo-beads were found mainly to consist of oxidized 125I-labeled EGF moieties. In contrast, the heterogeneous 125I-labeled EGF preparations obtained by using iodine monochloride, Protag-125, or lactoperoxidase-glucose oxidase-coupled beads (Enzymobeads) contained insignificant amounts of oxidized EGF entities. Ligand equivalence analysis (LEA) of distinct HPLC column fractions, obtained after preparative separation of Chloramine T-125I-labeled EGF, showed that the receptor-binding affinity of the tracer in all subfractions was less than the affinity of unlabeled EGF. This implies that HPLC purification of these 125I-labeled EGF preparations does not yield 125I-labeled EGF preparations with ligand equivalence. However, all but one HPLC column fraction of Enzymobeads-125I-labeled EGF showed ligand equivalence. Despite the small amount of the nonequivalent component in the Enzymobeads-labeled tracer, the nonchromatographed 125I-labeled EGF preparation showed ligand equivalence. No significant differences were observed in the maximal binding capacity of the different 125I-labeled EGF preparations.

Abstract:

In this paper, a valinomycin-functionalized nano-sized magnetic solid-phase extractant (VFE) with the core-shell structure and the Fe3O4 nanospheres as the core is prepared. Related performances are characterized and tested by SEM, PPMS, XRD, FT-IR, TGA, EDS, ICP-MS, and AAS. The optimal extraction conditions are obtained, namely, temperature 50 and#176;C or higher, pH not less than 9.3, and equilibrium extraction time about 35 min. Recycling performance experiments show that the extraction ratio of rubidium ions after 5 extraction-elution cycles is still up to 85.3%. Extraction experiments with the simulated brine, industrial wastewater, and domestic wastewater show that the VFE exhibits good selective extraction ability for rubidium ions in these water systems. This research is expected to provide a new method or a new material for the separation, extraction, enrichment, and detection of rubidium ions in water systems.

Abstract:

We investigated the impact of the preparation of reach movements on visual perception by simultaneously quantifying both an objective measure of visual sensitivity and the subjective experience of apparent contrast. Using a two-by-two alternative forced choice task, observers compared the orientation (clockwise or counterclockwise) and the contrast (higher or lower) of a Standard Gabor and a Test Gabor, the latter of which was presented during reach preparation, at the reach target location or the opposite location. Discrimination performance was better overall at the reach target than at the opposite location. Perceived contrast increased continuously at the target relative to the opposite location during reach preparation, that is, after the onset of the cue indicating the reach target. The finding that performance and appearance do not evolve in parallel during reach preparation points to a distinction with saccade preparation, for which we have shown previously there is a parallel temporal evolution of performance and appearance. Yet akin to saccade preparation, this study reveals that overall reach preparation enhances both visual performance and appearance.

Abstract:

Biomass, a renewable carbon source which can be processed using biorefinery system as an alternative of the conventional petroleum-based refineries. Aromatic precursor molecule synthesis involves chemical synthesis of fossil-fuel-based starting materials, such as benzene and xylene. These energy-intensive processes are usually producing many byproducts along with the desired molecule. If aromatic molecules can be extracted from natural resources involving minimum chemical conversions, that can be advantageous. Most of the reported approaches are expensive in nature and the outcomes with lower yield. Microbial fermentation of the lignocellulosic derivatives are ideal to establish sustainable society. In this chapter, we will focus on the aromatic building block preparations starting from nonedible feedstock such as kraft pulp. Aromatic aminobenzoic acid (3-amino-4-hydroxybenzoic acid) preparation from renewable resources and its use in various polymer preparations, such as polyaniline, polyester, and polybenzazole will be discussed here.

Abstract:

The ability to prepare effectively to execute complex skills under pressure is crucial in a number of performance-focused professions. While there is emerging evidence of best practice little research has sought to compare preparation strategies across professions. As a result, the aim of this research was to explore the approaches employed within a number of professions and whether there are similarities in the techniques and strategies adopted. Participants were 18 “performers,” purposefully selected from sporting, musical, performing arts, and medical domains. Participants were interviewed individually to gain an understanding of each participant’s preparation strategies and the functions these strategies fulfilled. The data were thematically analyzed using interpretative phenomenological analysis. Results suggest that there are similarities in both behavioral and mental strategies adopted across professions. Future research should seek to explore the transferability of developmental approaches.

Abstract:

Social loafing describes the loss of motivation and effort within group situations. The study proposed to answer the question of whether social loafing also affects preparation for a group task. It was expected that participants preparing for an individual task would show a better quality of preparation than participants anticipating a group task. Furthermore, the correlation between social loafing during preparation (preloafing) and social loafing during the main task was examined. In a pilot study conducted first, preloafing was found in a sample of male students. The main study showed the same effect for females on a grip-strength endurance task. Contrary to expectations, the correlation between preloafing and social loafing was only moderate. Theoretical implications of the phenomenon are discussed.

Abstract:

Ternesite–ye’elimite (TCSA) cement is a new type of environmentally advantageous binder prepared by introducing ternesite, a reactive phase, into belite calcium sulfoaluminate cement clinker. This paper reports the laboratory production of TCSA cement by the addition of minor elements to achieve the coexistence of ternesite and ye’elimite. The influence of dopants on the mineralogical composition of clinkers and the clinkering conditions for the preparation of TCSA cement clinkers were investigated by X-ray powder diffraction and scanning electron microscopy. The mechanical properties and hydration products of the cement pastes were also studied. The results indicated that the addition of CaF2, P2O5 and Na2O can promote the coexistence of ternesite and ye’elimite, and that Na2O is the most effective candidate. TCSA cement clinkers could be successfully prepared at 1150 °C for 30 min by doping 0.3% Na2O. The TCSA cement clinkers exhibited shorter setting times than the BCSA cement clinkers. The later strength of TCSA cement showed a significant increase compared with BCSA cement. The effect of Na2O was different on the strength development for TCSA and BCSA cement. The dissolution of ternesite could promote the formation of ettringite. The reactivity of belite was higher in TCSA cement due to the formation of strätlingite.

Abstract:

A novel microspheres adsorbent was prepared by the emulsion-congealed crosslinking method. The gelatin was as raw material and glutaraldehyde was as the crosslinking agent. The product was characterized by AFM, Zeta Potential Tester and SEM. These results showed that there were some irregular protuberances and grooves on the surface of gelatin microspheres. The relative surface roughness namely Ra was equal to 2.469E+01nm. The isoelectric point of gelatin microspheres was 3.2. Their morphology was almost not affected by treatment of the acid and alkali, and the performance of the acid and alkali resistance was superior. The result of desorption experiment showed that the regeneration ability of gelatin microspheres was stronger in the alkali solution than that in the distilled water. The optimum desorption temperature was 30°C. The desorption process got to balance for 80min. The desorption rate got to 88% in the alkali solution and regeneration effect was obvious. The result of the second-adsorption experiment showed that the desorbed adsorbent which was used in the second-adsorption experienced the same as the first-adsorption process. And the saturated adsorption capacity changed a little. So the gelatin microspheres can be recycled.

Abstract:

The key influences of foamed concrete and the optimum preparation technology were studied. The performance of foamed concrete was analyzed by the compressive strength testing, SEM. Results show that the flowability of cement paste is good when water-cement ratio is 0.4. The amount of foam added in sulphoaluminate cement is not able to exceed 3.5L/kg. However, the dilution multiple of foaming agent is near concentration and the mixing time depends on the foam quantity. When the water-cement ratio is 0.4, the foam quantity is 3 L/kg and the foaming agent is diluted 30 times. When the mixing time is 60s, the dry density is around 380kg/m3 and the 7d compressive strength reaches to 0.9MPa.

Abstract:

Zirconia fiber not only can be used for a long time in 1600°C, but also has low thermal conductivity at high temperature. Due to the excellent insulation performance, it has a broad application prospect in aerospace, aviation, energy and other areas. In the present study, we chose yttrium stabilized zirconia fibers and nanometer zirconia powder as main material and adding soluble starch, zirconium sol as low temperature and high temperature binder. Rigid zirconia fiber board was prepared by material slurry, filter shaping, stripping drying and high temperature calcination. After high temperature calcination of 1600°C for 12h, sample pore are mainly concentrated in 25-75μm, bending strength performance is best when the adding amount of nanometer zirconia powder was 7%, the thermal conductivity is only 0.132 W·m-1·K-1 at 1400°C.

Abstract:

PVA hydroscopic films were prepared by solution and tape casting method. PVA 1799 was selected as the best material of hygroscopic film. This work evaluated the effect of PVA concentration, glycerol and methylcellulose (MC) on mechanical property, transmittance and absorbability of the film. The result showed that the transmittance of PVA film was high, and that plasticizer and MC had little effect on it; while the addition of MC affected the haze of PVA film greatly, the haze increased along with the increasing of adding amount of MC. The suitable concentration of PVA, glycerol and MC was 7%, 0.8%, 0.18%, respectively..

Abstract:

This article presents pilot study results of two leadership performance assessments, designed for a California principal preparation program and embedded in preparation using two learning approaches. The pilot study had two purposes: to evaluate the assessments‘ content validity and to evaluate the candidates’ leadership skills as demonstrated through their assessment products and an independent self-assessment tool. The evidence showed the tasks to be valid and useful tools for formative leadership development for different candidates and school settings. Participant feedback on the assessments‘ benefits and independent self-assessment ratings provided construct validation. We concluded that these are promising assessment tools for programs’ use in candidate assessment.

Abstract:

PurposeThe purpose of this study is to investigate the effect of chlorination on the structure and properties of reclaimed rubber and to discuss the feasibility of a novel method to chlorinate reclaimed rubber.Design/methodology/approachA series of chlorinated reclaimed rubber with different chlorination degrees (CD) was prepared by suspension chlorination in aqueous phase (SCAP). Their structure and performance were characterized by Fourier transform infrared spectrometer, energy dispersive spectroscopy, scanning electron microscopy, thermogravimetric and mechanical property test.FindingsThe chemistry structure, mechanical performance and heat resistance of CRR is affected greatly by its CD.Research limitations/implicationsAlthough in the present work only chlorination of reclaimed rubber is researched, but this method can be used to modify other recycled rubber.Practical implicationsSCAP is a useful method to produce CRR, and it is feasible for production of chlorinated recycled rubber in large scale. The present work provides a new strategy to fabricate new materials based on recycled rubber.Social implicationsChlorination of reclaimed rubber by SCAP is useful to convert waste rubber into new materials, and it is useful to decrease environment pollution.Originality/valueSCAP method provides a new technology to chlorinate waste rubber with many merits, such as chlorination rate of RR is accelerated and the reaction can be controlled or adjusted easily. Moreover, conversion of chlorine is increased remarkably.
