Background: During the past few years, with the increase in air traffic and the expansion of airports, very few industries had such a large spatial development and movement impact as that of airport-related clusters or airport regions. Although much research was done on the various impacts of the airport industry, very little research was done on the air cargo industry in airport regions.Objectives: This article specifically explored the unique spatial relationships, impacts, trends and movement patterns of the air cargo industry within a typical airport region.Method: The article focused on the OR Tambo International Airport in Gauteng, South Africa, as a case study and was informed by an extensive quantitative spatial and land use analysis and modelling of the study area.Results: The article presented findings and insights on the movement patterns and relationships between (1) the airport facility and (2) the spatial configuration of air cargo industries in the particular airport region. These findings also provided some framework for a possible spatial model and guideline that could assist in steering and managing development and movement patterns in airport regions.Conclusion: The article provided new insights and understanding on the spatial dynamics of airport regions and the air cargo industry, ultimately addressing some gaps in this knowledge field. The article in the end highlighted the need for a different and novel approach to the planning and management of the air cargo industry in airport regions and a basis for further research.

Ons verstaan Hermeneutiek in die tradisionele sin. Ons gebruik die term dus nie in die sin van die sg. Nuwere Hermeneutiek, wat bykans die hele teologie onder “Hermeneutiek” as die hele proses van “verstaan” van die Skrifte wil insluk nie

A technique to estimate the performance of single site location (SSL) based on high-frequency direction finding for reigning ionospheric propagation conditions is described. This technique is based on classic propagation information (maximum useable frequency, frequency for optimum traffic, optimum working frequency, highest possible frequency, lowest possible frequency, etc.) which can be deduced by ray tracing through an ionospheric model such as the International Reference Ionosphere. The correlation between the elevation angle measured by an interferometric direction finder and the angles corresponding to the propagation conditions is used to assign a quality factor to the calculated SSL ground range result.

Uit Matt. 16:16–18 blyk dat daar ’n allernouste verband deur Christus gelê is tussen kerk en belydenis. Die belydenis staan ook in onmiddellike verband met die bediening van die sleutelmag (vgl. vr. 84 H. Kateg.).
