The behaviour of semi arid residual soils derived from the weathering of Johannesburg quartzite are difficult to predict because of their heterogeneous particle constitution and weakly bonded structure. The collapse behaviour of undisturbed and remoulded weathered Johannesburg quartzite was investigated; and the reliability of the collapse settlement data was also evaluated. The results showed ...

THE 1959 Mental Health Act emphasises the need to integrate psychiatric patients with the community at large rather than to isolate them from it, as hitherto. This identification with the normal community has been the Ministry of Labour's approach to the employment of disabled people since the time of the Disabled Persons (Employment) <4ct of 1944. For the past 17 years all disabled people, whe...

Values of site factors in numerical simulation can have profound effects on the calculation accuracy. In order to fully understand the performance of rigid-pile composite foundation in tall buildings, this article set up an overall FEA model of a 25-storey frame-tube structure by considering the interaction of superstructure, foundation and ground. Thereafter, a detailed parametric study was pe...

According to the analysis of settlement configuration of Jiangzhai in its first period, this paper places emphasis on the spatial knowledge reasoning about the characteristics of vector graphs of relics. With the special designed spatial rule knowledge base put into practice, this paper adopts the precondition base and the consequent base to respectively store the precondition and consequent of...

The global degradation of coral reefs is having profound eVects on the structure and species richness of associated reef Wsh assemblages. Historically, variation in the composition of Wsh communities has largely been attributed to factors aVecting settlement of reef Wsh larvae. However, the mechanisms that determine how Wsh settlers respond to diVerent stages of coral stress and the extent of c...

An experiment was conducted to investigate the effect of collector materials and position on Pinctada margaritifera spat attachment. Settlement on polyethylene pipes (54.6%) was significantly higher (P < 0.05) than on plastic baskets (25%). Significantly higher (P < 0.05) spat catch was recorded from the collectors which were installed on lower height of settlement tank than upper. The number o...

The Pomacentridae (damselfish) and Apogonidae (cardinalfish) are among the most common fish families on coral reefs and in the aquarium trade. Members of both families undergo a pelagic larvae phase prior to settlement on the reef, where adults play key roles in benthic habitat structuring and trophic interactions. Fish-associated microbial communities (microbiomes) significantly influence fish...

Functional and structural changes of regional system are ongoing spatial changes that form patterns of spatial organization, depending on dominant regional forces and factors. Spatial structure of West Azerbaijan province experienced significant changes during 15 years; thus, the present research aim to investigate the manner of spatial distribution of two variables of population and activity, ...
