11	Digital Soil Mapping of the Purdue Agronomy Center for Research and Education Shams R Rahmani (8300103) 07 May 2020 (has links) This research work concentrate on developing digital soil maps to support field based plant phenotyping research. We have developed soil organic matter content (OM), cation exchange capacity (CEC), natural soil drainage class, and tile drainage line maps using topographic indices and aerial imagery. Various prediction models (universal kriging, cubist, random forest, C5.0, artificial neural network, and multinomial logistic regression) were used to estimate the soil properties of interest.

12	The feasability of implementing community based care for moderately mentally-retarded persons in a specific centre in Port Elizabeth Ngcanga, Nosipho Margaret 11 1900 (has links) The purpose of this study was to investigate the possibility of implementing community based care for moderately mentally retarded persons in a specific centre in the Port Elizabeth area. The objectives of the study were to identify • the needs of the moderately mentally retarded children. • the physical, psychosocial and vocational rehabilitation means of meeting these needs. • how involved the communities, parents and government were in the care of moderately mentally retarded children. A quantitative, exploratmy and descriptive design was used. A sample of 50 moderately mentally retarded children was utilised. Data were collected by means of questionnaires and semi-structured interviews. The major research findings indicate that community care for MMRPs could only be feasible with sufficient resources, expertise and community involvement. All these aspects appeared to be lacking in the centre where this research was conducted raising questions as to benefits which the mentally retarded children and their parents and the community could derive from these services. However recommendations were made on identified shortcomings, problems and needs. / Health Science / M.A.(Nursing Science) Care of mentally retarded persons Community based mental health care Mental health Mental retardation Moderately mentally retarded persons Reconstruction and development programme 362.30968752
