Opis:
The study investigated the learner perceptions of a CALL component in a blended language learning context. 52 Taiwanese college students attended instructional classroom sessions and did weekly online assignments in the form of interactive web-based exercises over one semester. Their learning performance was measured by means of two computer-based language assessments at the mid-point and final part of the semester. Learners’ perceptions of the interactive web-based exercises were elicited by a computerized survey conducted at the end of the semester. The results reported on the survey revealed that participants perceived the interactive web-based exercises as interesting but only modestly so. This was probably attributable to the difficulty level of the created exercises and a lack of diverse exercise formats. Even so, having easy access, receiving immediate feedback, allowing multiple attempts, and enabling self-paced learning were mentioned as benefits of the constructed exercises. More importantly, most participants reported the effectiveness of these exercises in improving their reading comprehension and vocabulary leaning. This confirmed language assessment results that demonstrated significant gains in reading comprehension and vocabulary knowledge. Implications include suggestions for language teachers and program developers for improving the way web-based learning activities are created and implemented.

Opis:
Based on Energy Calculation Star program and molecular dynamic method, three designed 2,3-bis(hydroxymethyl)-2,3-dinitro-1,4-butanediol tetranitrate-based (BHDBT) propellants are firstly reported and their physicochemical performance are investigated. Results suggest that compared with HMX-based and CL-20-based propellants, the specific impulses of all BHDBT-based propellants surpass or approximate 280 s, which indicates the latter have the potential to be high-energy propellants. The diffusion coefficient of plasticizers in BHDBT-based propellant decrease as the temperature reduces, and reduce in the order: Bu-NENA > TMETN > BTTN. The densities of all BHDBT-based propellants surpass or approximate 1.7 g/cm3. The comparison of elastic constants, Poisson’s ratios and K/G values indicates that the mechanical properties of three BHDBT-based propellants increase in the order (by plasticizer): Bu-NENA < TMETN < BTTN. The bond length analysis of C–NO2 and O–NO2 bond in BHDBT suggests that the former is the trigger bond in the BHDBT-based propellants, and the safety of BHDBT-based propellants and BHDBT crystal decreases in the order: GAP/BTTN/Al/BHDBT > GAP/Bu-NENA/Al/BHDBT ≈ GAP/TMETN/Al/BHDBT > BHDBT. In conclusion, GAP/BTTN/Al/BHDBT propellant has the potential to be a novel high-energy propellant.

Objectives The aim of the study was to examine the relationship between workplace bullying, mental health and an intention to leave among nurses, and the mediating role of self-efficacy. Material and Methods This cross-sectional study was conducted among 385 nurses in Taiwan. Data were collected by means of self-report questionnaires, including the Negative Acts Questionnaire-Revised, the General Self-Efficacy Scale, the Chinese Health Questionnaire, and the Employee’s Turnover Intentions and Job Destination Choices Scale. Descriptive statistics, Pearson’s correlation and hierarchical regression analyses were used. Results Bullying was found to negatively correlate with self-efficacy and mental health, and positively with an intention to leave. Self-efficacy positively correlated with mental health, and negatively with an intention to leave. Hierarchical regression showed that bullying and self-efficacy were significant predictors of both mental health and an intention to leave. Self-efficacy partially mediated the relationship between bullying and mental health, as well as an intention to leave. Conclusions Self-efficacy acted as a mediator of workplace bullying, mental health and an intention to leave among nurses. It could protect victims from the devastating effects of bullying behaviors.

Maintaining clean and pristine nature is the key to the use of super clean coal (SCC) for coal-based materials or energy combustion. Herein, SCC is prepared by a new water-only cyclone method, and compared the surface characteristics with the SCC products obtained by conventional chemical deashing method. The results indicate that: FTIR analysis revealed that the chemical method changed the original functional group of coal; BET analysis revealed that the SCC products prepared by the water-only method maintained the micropore volume of the raw coal and yielded a uniform and concentrated distribution of pore sizes, however, the chemical method destroying the original pore structure in the coal; SEM-EDS analysis indicated that the surface of SCC particles that were deashed using the water-only cyclone method was smooth and neat, whereas those obtained using the chemical method were seriously corroded, had a rough surface, and the SCC particles were prone to acid residues and precipitates. This study opens an innovative, simple, and clean method for the preparation of SCC, which further expands and enhances the potential application value of SCC.

Opis:
PIV technology was used to investigate the influence of the particles’ relevant parameters on the instantaneous movement characteristics in the sandblast cylinder under the circumstance of different particle sizes, different section heights and different stacking conditions. As the diameter increased, particles had a greater velocity and energy when approaching the wall, which would cause a serious abrasion. The influence of test selection factors on the particles’ radial velocity of particles was greater than that on axial velocity. The radial velocity and axial velocity on the surface of the cylindrical section were all reduced to a lower level when the particles approach the tank wall. When r > 0.3 R, the particle velocity maintained at a higher level, but then decreased slowly when r > 0.7 R. Therefore, the abrasion of the conical section of the sandblast cylinder when r > 0.3 R should be paid more attention to.

Opis:
Phage ΦC31 integrase is a potential vector for the insertion of therapeutic genes into specific sites in the human genome. To understand the mechanism involved in ΦC31 integrase-mediated recombination, it is important to understand the interaction between the integrase and cellular proteins. Using a yeast two-hybrid system with pLexA-ΦC31 integrase as bait, we screened a pB42AD human fetal brain cDNA library for potential interacting cellular proteins. From the 106 independent clones that were screened, 11 potential interacting clones were isolated, of which one encoded C-terminal fragment of Sp100. The interaction between Sp100 and ΦC31 integrase was further confirmed by yeast mating and co-immunoprecipitation assays. The hybridization between a ΦC31 integrase peptide array and an HEK293 cell extract revealed that residues 81RILN84 in the N-terminus of ΦC31 integrase are responsible for the interaction with Sp100. Knocking down endogenous Sp100 with Sp100-specific siRNA increased ΦC31 integrase-mediated recombination but did not impact reporter gene expression. Therefore, endogenous Sp100 may interact with ΦC31 integrase and inhibit the efficiency of ΦC31 integrase-mediated recombination.

This article introduces the study of peripheral clamping for large-aperture laser mirrors in high power laser facilities. Some multi-point clamping schemes were experimentally tested, the results of the experiments show that these schemes cannot meet the technical requirements, and in the simulation analysis, we explain the reason for this phenomenon. It is concluded that the additional bending moment caused by the non-ideal process factors in the multi-point clamping is the main cause for the surface distortion. Based on the above conclusions, we carried out research on minor-point clamping. Experimental verification of the minor-point clamping were done, the results show that the minor-point clamping can meet the requirements of technical indicators in whole process. This work can provide a reference for the design of the large-aperture transport mirror clamping structure, which may be used in huge laser devices and telescopes.

In view of the disadvantages of the existing electrostatic separation process of decommissioned photovoltaic modules, which can only achieve the separation of fine silicon wafers and glass and has high energy consumption, a new process to solve the efficient dry separation of coarse silicon wafers and glass in decommissioned photovoltaic modules is proposed- the vibration separation method. Based on the theoretical analysis of the vibration separation of flaky silicon wafer and polyhedral glass particles, the effects of feed size, feed amount, vibration voltage, vibration frequency, horizontal inclination angle and longitudinal inclination angle on the product indexes of wafer and glass separation were investigated by single factor experiment. The optimal experimental conditions were obtained as follows: feed particle size +0.83mm, feed amount 0.15 t/h, vibration voltage 190 V, vibration frequency 48 Hz, horizontal inclination Angle 8°, longitudinal inclination Angle 3°. Under this optimized condition, the content of metal Si in the obtained silicon wafer product is 84.47%, the recovery rate of is 83.73%, the content of impurity SiO2 is 1.09%, and the content of SiO2 in the obtained glass product is 65.69%, and the recovery rate is 98.95%, the impurity metal Si content is 0.56%. This study provides a research idea for the industrial separation of silicon wafers and glass from decommissioned photovoltaic modules.

Opis:
A novel approach for the measurement of information content of light field on the image plane illuminated by an incoherent light source has been proposed according to Shannon’s information theory. We put forward a hypothetical concept named "coherent wavelet source" on an incoherent light source which can form an independent coherent signal on the object surface based on the expression of mutual intensity on the object surface. As a result, the number of independent coherent signals on the object surface can be made out by dividing the whole illumination source on a coherent wavelet source size. Meanwhile, the maximum number of degree of freedom of light field which can reach the image plane is given based on the structure of imaging system. Concrete algorithm for the information content of the imaging light illuminated by a 1D linear light source and a 2D circular light source are presented.

The effectiveness of the controller has been verified by simulation and an experiment. The results show that the equivalent moment of inertia is increased by 5 times, and the step response overshoot of the speed system is 4.1%. By adding a random disturbance, the sinusoidal tracking errors of the speed and torque systems are 0.05 r/min and 0.09Nm, respectively.

Opis:
Constrained by the micro-space structure, it is proposed to use platinum wire incandescent ignition combustion mode to achieve the operation of internal combustion engine. However, the combustion test of the platinum wire incandescent ignition in miniature piston internal combustion engine shows: the combustion mode of micro-space platinum wire incandescent ignition has a poor combustion characteristic, low heat release rate, long combustion duration, and low combustion pressure. Therefore, a homogenous charge compression ignition mode is proposed to realize the operation of miniature internal combustion engine. However, it is found that the compression combustion cannot be come true in the cold start-up state of the micro engine. And the compression combustion in the first cycle was realized by the way of increasing the temperature of the cylinder block and platinum wire appropriately. The results show that: The maximum heat release rate is obviously improved and the combustion duration shortened by 28.6ºCA, and pmi increased by 76%. So, a novel hybrid combustion mode of in-cylinder compression combustion supported by the platinum wire incandescent ignition is put forward, through the way of adjusting the temperature of platinum wire, and this combustion mode is regarded as the ideal combustion mode of micro reciprocating piston internal combustion engine.

Opis:
Crystal density is a basic and important parameter for predicting the detonation performance of explosives, and nitrate esters are a type of compound widely used in the military context. In this study, thirty-one aliphatic nitrates were investigated using the density functional theory method (B3LYP) in combination with six basis sets (3-21G, 6-31G, 6-31G*, 6-31G**, 6-311G* and 6-31+G**) and the semiempirical molecular orbital method (PM3). Based on the geometric optimizations at various theoretical levels, the molecular volumes and densities were calculated. Compared with the available experimental data, the densities calculated by various methods are all overestimated, and the errors of the PM3 and B3LYP/3-21G methods are larger than those of other methods. Considering the results and the computer resources required by the calculations, the B3LYP/6-31G* method is recommended for predicting the crystalline densities of organic nitrates using a fitting equation. The results obtained with this method are slightly better than those reported by Keshavarz and Rice. In addition, the effects of various groups (such as –ONO2, –OH, –Cl, –O–, and –CH2–) on the densities are also discussed, which is helpful for the design of new molecules in terms of practical requirements.

Objectives: To investigate the association between polymorphisms in the p53 pathway genes and chromosomal damage in vinyl chloride (VC)-exposed workers. Materials and Methods: Cytokinesis block micronucleus test was performed in 310 VC-exposed workers and 149 non-exposed workers to determine chromosomal damage. The polymerase chain reaction and restriction fragment length polymorphism technique were used to detect six SNPs in the p53 pathway genes involved in the cell cycle. Results: There was a highly significant dose-response relationship between VC exposure and chromosomal damage. Individuals carrying the variant genotypes were at higher risk for chromosomal damage compared with their wild type genotype: p53rs1042522, MDM2 Del1518rs3730485, MDM2rs2279744 and GADD45Ars532446. On the other hand, individuals possessing the variant genotype of CDKN2A rs3088440 had significantly decreased risk compared with the corresponding wild-type. Conclusions: Genetic polymorphisms in P53 pathway genes may have an impact on VC-induced chromosomal damage.

Since the reform and opening-up, China has actively followed overseas costume trends and bidden farewell to the era of uniforms. It has gone through evolution from collective imitation to physical liberation to the advocacy of diversified individuality to this new age, where the Chinese culture of costume is radiant with self-confidence. The culture of ancient Chinese costume has a long history with extensive and profound connotations. This paper, from the perspective of cultural confidence, adopts the propagation mode of '5W' to discuss the overseas dissemination of ancient Chinese costume culture, the specific content of Chinese-foreign exchange, and theoretical approaches in the theoretical framework of communication based on the case of 'American Tour of Innovative Design Works of Ancient Chinese Costume Culture', organised by Jiangnan University in 2018, in a bid to serve as a reference for the narration of the national story, the communication of a national voice and the creation of a national image.
Od czasu reformy i otwarcia Chiny aktywnie podążały za zagranicznymi trendami kostiumowymi i pożegnały się z erą uniformów. Chiny przeszły ewolucję od zbiorowego naśladowania, przez wyzwolenie i popieranie zróżnicowanej indywidualności, aż do tej nowej ery, w której chińska kultura kostiumowa promieniuje pewnością siebie. Kultura starożytnych chińskich strojów ma długą historię z rozległymi i głębokimi konotacjami. W pracy, z punktu widzenia zaufania kulturowego, przyjęto tryb propagacji "5W". W artykule omówiono proces zagranicznego rozpowszechniania starożytnej chińskiej kultury kostiumowej, specyficznej treści chińsko-zagranicznej wymiany oraz teoretycznych podejść w ramach komunikacji w oparciu o wystawę "American Tour of Innovative Design Works of Ancient Chinese Costume Culture", zorganizowaną przez Uniwersytet Jiangnan w 2018 roku. Wydarzenie to posłużyło, jako punkt odniesienia dla narracji narodowej historii, przekazywania głosu narodowego i tworzenia narodowego wizerunku.

A novel feature extraction method has been proposed to improve the accuracy of the pineapple ripeness classification process. The methodology consists of six stages, namely: image acquisition, image pre-processing, color extraction, feature selection, classification and evaluation of results. The red element in the RGB model is selected as the threshold value parameter. The ripeness of pineapples is determined based on the percentage share of yellowish scales visible in images presenting the front and the back side of the fruit. The prototype system is capable of classifying pineap ples into three main groups: unripe, ripe, and fully ripe. The accuracy of 86.05% has been achieved during experiments.
