The paper proposes a model unfolded for occupational safety aspects inclusion in the design and management of change stages for a piece of machinery. The “Integrated Safety - Technical Equipment” (ISTE) model substantiates a logical connection between various task-based features to be fulfilled, hazardous areas and occurrences, hazards, risk assessment, ways to wedge in, workplace characteristics, the effect of the working environment, work crew as well as apparatus, tools and/or basically corresponding to and following a set of prior theoretically grounded guidelines, found in literature. At the same time, the paper gives the outline of the case study performed to give proof of the practical model’s, illustrating operational safety design for a mechanical press line, used for sheet metal milling. Resorting to the developed model, it was performed the design, construction and assembling of the automatic press line which is compliant in terms of occupational safety.

This study assesses the operational safety and security of a category one airport in Nigeria, using the Nnamdi Azikiwe International Airport, Abuja (NAIA) as the case study airport. Data were sourced using structured questionnaire and oral interviews. A total of 180 questionnaires were administered and 165 questionnaires were retrieved, amounting to a 91.7% rate of response. The structured questionnaire used aimed at identifying various safety and security parameters in the study area. This study examined the trend of the effectiveness of safety and security variable in airport operations, safety and employee’s attitude towards safety risk management using the Multicriteria Decision Analysis model to achieve this objective. The results show the weighty level, satisfaction index and effective index of the safety and security parameters used in the analysis with their score and effective index graph. Recommendation on how to improve the airport safety operations were made following policy implication on how to improve the safety management system of the airport.

Squats are a type of rolling contact fatigue on the top of rails of straight tracks or shallow curves. In some countries they have become a major type of rail damage. Although it is widely recognized that preventive and early corrective actions are cheaper than late remedies such as rail replacement, timely treatment is hindered by the lack of automatic detection of early squats. So far, the treatment of squats has mainly been dependent on ultrasonic detection, which detects deep cracks and is applicable only to severe squats. The life cycle costs (LCC) of squat-infected track are therefore high. The operational safety and availability of the networks are also adversely affected. Based on a new method which detects initiating squats, this paper proposes a methodology for squat related LCC reduction. First a squat classification is introduced that facilitates early identification of squats. Then the growth phases of squats are discussed; typical growth rate of squats is analyzed, and thereupon based threshold values for minimum action by rail grinding are proposed. After a review of the currently available detection methods, the new detection method is presented, with results of field test demonstrating the capability of the method to detect light squats. Finally, a case study of the LCC of a monitored squat-infected track section shows that the proposed treatment can significantly reduce the LCC. In addition, operational safety and network availability can also be improved.

The 1960S

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.

Modern polishing, precision machining and microindentation techniques allow the processing and mechanical characterization of ceramics at nanometric scales and within entirely plastic deformation regimes. The mechanical response of most ceramics to such highly constrained contact is not predictable from macroscopic properties and the microstructural deformation patterns have proven difficult to characterize by the application of any individual technique. In this study, TEM techniques of contrast analysis and CBED are combined with stereographic analysis to construct a three-dimensional microstructure deformation map of the surface of a perfectly plastic microindentation on macroscopically brittle aluminum nitride.The bright field image in Figure 1 shows a lg Vickers microindentation contained within a single AlN grain far from any boundaries. High densities of dislocations are evident, particularly near facet edges but are not individually resolvable. The prominent bend contours also indicate the severity of plastic deformation. Figure 2 is a selected area diffraction pattern covering the entire indentation area.
