BACKGROUND |
Image superimposition is a part and parcel of two-dimensional radiography. However, some overlappings are a result of radiographic technique itself. The technique induced superimposition of zygomatic buttress on apices of maxillary molars is common in bisecting angle technique (BAT), which affects the endodontic perfor... |
MATERIALS AND METHODS |
A total of 62 patients requiring endodontic treatment for at least one maxillary molar were recruited in this cross-sectional study. One tooth from every patient was subjected for two periapical radiographs, one with each BAT and MBAT respectively giving a total of 124 radiographs. Each radiograph was recorded as accep... |
RESULTS |
With MBAT, the acceptability was 82.3% (n = 51) compared with 43.5% (n = 27) when BAT was employed. The statistically significant difference was found between these two techniques (P = 0.000). The level of agreement between two oral radiologists in their interpretation was high (kappa index = 0.897). |
CONCLUSION |
Modified BAT was more accurate for periapical radiography of maxillary molars in preventing zygomatic superimposition and related technical errors than BAT.Safety of container ship (un)loading operations in the Port of Antwerp |
Purpose |
Economies of scale drive container ship owners towards ordering larger vessels. Terminals need to ensure a safe (un)loading operation of these vessels, which can only be guaranteed if the mooring equipment is not overloaded (lines, fenders and bollards) and if the motions of the vessel remain below set limits, under ex... |
Design/methodology/approach |
Motion criteria for allowing safe (un)loading of container vessels are established by considering the container handling process and existing international standards (PIANC). A case study simulation is presented where the behaviour of the moored vessel under ship passages is evaluated. Starting from a representative ev... |
Findings |
The study illustrates the influence of passing velocity and distance on the behaviour of the moored vessel, showing that when passing speeds are higher and/or distances lower than the reference event, safety limits are potentially exceeded. Possible mitigating measures, including the use of stiffer mooring lines and/or... |
Research limitations/implications |
This paper serves as a basis for future research on safety criteria and optimisation of the mooring equipment and configuration to deal with passing vessel effects. |
Practical implications |
The presented results can be used by ship and terminal designers to gain familiarity with passing vessel effects and adopt suggested best practice. |
Social implications |
By restricting the motions of the passing vessels, the focus and general well-being of the crane operator is enhanced, as is the safety of workers. |
Originality/value |
The paper provides a unique combination of container fleet observation, safety criteria establishment and case study application. |
Preparation of Substituted N-Methacryloxy Phthalimides for E-Beam Lithography |
Poly (methyl methacrylate) (PMMA) is a very good option for electron-beam resists, but suffers from poor radiation sensitivity and poor plasma etch resistance. These problems can be offset, at least in part, by functionalizing the PMMA with photo-labile, plasma etch-resistance groups. Toward this end, a series of N-met... |
In 2004 the increasing number of attacks on U.S. federal civilian agency computer systems caused the government to begin an active effort to protect federal civilian agencies against cyber intrusions.
