Opis:
Bragg-case synchrotron double-crystal images of stacking faults were studied in a slab prepared from a synthetic diamond of a good quality. The images of stacking faults in topographs taken on the tails of the rocking curve exhibited well pronounced interference fringes. The fringes were strongly dependent on the angular setting and they were less spaced further from the maximum. The experimental images were compared with those theoretically predicted from an application of plane-wave dynamical theory. A reasonably good correspondence between theoretical and experimental images was obtained. The theoretical images of stacking faults were dependent on the type of stacking fault, producing some difference in the first fringe.

Opis:
Bragg-case synchrotron section topographs were studied in parallel slabs cut from a synthetic diamond of a good quality. The topographs revealed the Pendellösung fringes and images of dislocations and other defects containing several fringe systems. The experiment provided the opportunity for studying of the theoretical dislocation images obtained by numerical integration of the Takagi-Taupin equations. A program employing a variable step of integration in the Bragg-case has been presented. The influence of the finite slit width and of the limited beam divergence on the theoretical images is also discussed.

Opis:
The Haruta method is used for stereoscopic observation of a 1.5 × 4 × 4 mm$\text{}^{3}$ cuboctahedral synthetic diamond with transmission double-crystal topography. The experiments were performed using a synchrotron double-crystal arrangement with asymmetrical diamond 220 reflection selecting 1.0 Å radiation. The appropriate Haruta pairs were matched from a series taken with positions on the rocking curve changed by small intervals. A reasonable stereoscopic effect was observed for most defect images, particularly dislocations, stacking faults and growth sector boundaries. It was established that some interference fringes do not produce good stereoscopic effects and appear on the exit surfaces of the diamond.

Opis:
Meeting the educational needs of students currently requires moving toward collaborative electronic and mobile learning systems that parallel the vision of Web 2.0. However, factors such as data freedom, brokerage, interconnectivity and the Internet of Things add to a vision for Web 3.0 that will require consideration in the development of future campus-based, distance and vocational study. So, education can, in future, be expected to require deeper technological connections between students and learning environments, based on significant use of sensors, mobile devices, cloud computing and rich-media visualization. Therefore, we discuss challenges associated with such a futuristic campus context, including how learning materials and environments may be enriched by it. As an additional novel element the potential for much of that enrichment to be realized through development by students, within the curriculum, is also considered. We will conclude that much of the technology required to embrace the vision of Web 3.0 in education already exists, but that further research in key areas is required for the concept to achieve its full potential.

Opis:
Although under-reporting of work-related injuries by workers is recognized as a significant problem in construction and other industries, little is known about the specific reasons for such occurrences. Qualitative and quantitative methods were used in this study to (a) identify reasons why construction workers may choose not to report work-related injuries, and (b) to investigate the frequency of the identified reasons. Twenty-seven percent of a sample of construction workers (N = 135) indicated that they had failed to report a work-related injury. The most frequent reasons given were related to perceptions of injuries as "small" and "part of the job" as well as fear of negative consequences, which may follow injury reporting. These findings are discussed in terms of practical implications. Strategies to overcome these reasons are suggested to decrease the under-reporting of injuries in the construction industry.
