The geological formations of Maputo City, which are mainly unconsolidated materials with soil like properties, are described in terms of their engineering geological and geotechnical characteristics with relevance to their distribution patterns and spatial trends. Problematic conditions such as collapse potential characteristics, loose aeolian sand dune deposits and loose sand plains characterize many of the materials. The geological characteristics combined with anthropogenic interference such as intensive urbanization with inappropriate land use, construction in sensitive areas like steep sandy slopes has led to many problems including slope stability. Foundation problems with building settlement and gully erosion also occur. The aim of this research was to study the engineering geological characteristics and the geotechnical properties of the geological formations of Maputo City and various related problems. Special relevance has been given to the understanding of three specific problems: building damage, gully erosion and slope instability. The geological formations are predominantly sandy (coarse to very fine sand) with very low clay content, are non-plastic and are classified as from the group SP-SM which are poorlygraded sand with silt. The majority of the materials are loose and normally consolidated with a high level of residual strength. Assessment of collapse settlement through double consolidation technique indicated soil compressibility and significant sensibility to collapse upon wetting. Truly collapsible soils that show full collapse of the soil structure were identified in 33% of the tested materials where the highest collapse behaviour reached values above 5%, predicted to cause moderate trouble in foundation design. Some of the bonded materials are bonded (evident in 67% of samples tested). Bonding was confirmed by comparing the compressibility of the undisturbed and remoulded samples. The remoulded samples showed a significantly higher compression than that of the bonded materials as part of the stress applied is carried by the bonds themselves, as the bonded material is stiffer than the same without bonds. The curves of the remoulded samples were used to establish the limit between the stable and meta-stable states of the material. A qualitative evaluation of the erosion susceptibility was investigated by physical tests such as the crumb test, shear strength and chemical indicators while a quantitative evaluation of the erodibility characteristics was obtained using a flume test. Some correlations were found between the results of various methods. Almost all samples that were found to be dispersive with ESP were also dispersive with TDS vs. %Na and SAR. Results of the flume erodibility test have very little correlation with the chemical properties related to dispersion revealing that the erosion susceptibility and gullying in Maputo City have more relation to the physical processes than to the dispersion related chemical properties of the soils. The positive identification of dispersive and erodible soils can only be carried out using a combination of various techniques. Therefore, a new rating system for erosion susceptibility of sandy soils combining the physical and chemical factors of dispersion is proposed including the flume test, crumb test, TDS/%Na, SAR and ESP. The proposed rating system was applied to the tested soils of Maputo City. Fifteen samples (83% of the rated samples) were classified with intermediate susceptibility to erosion while 3 samples (17%) were classified as having a low susceptibility to erosion. The highest rating scores were obtained by the same samples that showed dispersive behaviour with SAR, ESP and TDS/%Na. This group of samples was of intermediate erodibility in the flume test. The slope instability mechanisms observed in Maputo City are predominantly rotational failures with a mass of soil sliding along a curved surface of rupture followed by sand flow at the toe as failure occurs in the presence of excess water. Four groups of factors account for the slope instability problems in Maputo City: geomorphological causes, physical and meteorological causes, geological and geotechnical properties of soils, and anthropogenic causes. The mechanism of failure is mostly due to the loss of matric suction of soils in the presence of rainwater and possibly from destruction of bonding agents. Factors of safety values indicate that the slopes are generally unstable with the control being the slope angle. The slopes in the Polana-Caniço and Ferroviário Quarters show high factor of safety values but is the area most affected by slope instability. Slope failure in these areas is intrinsically caused by anthropogenic factors related to inappropriate land use planning. The gully sidewalls are unstable as the slope created is very steep. The slope at Friedrich Engels Avenue causes most concern due not only to the slope height and angle but also to the size and number of buildings constructed at the crest, mainly high rise buildings along the Julius Nyerere Avenue, the integrity of which could be threatened by a landslide event (this slope has recently been affected by active landslides). / Thesis (Ph.D.)-University of KwaZulu-Natal, Westville, 2011.

M.Phil. / The Motraco transmission system is a classical case illustrating the increase in power transfer of a network considering the possibility of a voltage collapse. This case study was used in the dissertation to find a techno-economical solution for the Motraco system to increase the power transfer to satisfy an additional load. The Motraco power system is operating close to a voltage collapse at present. A voltage collapse will be experienced if additional load is added at the Maputo substation. The possibility of a voltage collapse can be reduced if the power transfer capability of the Motraco power system is increased. Various technologies can be used to increase the power transfer of the Motraco power system. The technologies used in this study to increase the power transfer were limited to the following: • Adding shunt capacitor banks at critical locations in the network • Adding a series capacitor bank on an existing 400 kV transmission line • Adding an additional 400 kV transmission line • Adding a series capacitor bank on the new 400 kV transmission line The correct use of the combination of the shunt capacitor banks, series capacitor bank and the new transmission line contributes to: • support voltages in the network; • reduce the transmission losses; and • increase the fault levels at the receiving end. The principles used in this dissertation can be used to increase the power transfer limit of any power system with the same characteristics.

Esta dissertação tem por objetivo descrever o léxico da Língua Portuguesa falada por universitários de Maputo, Moçambique. Sob um viés sincrônico, o método de coleta de dados agrega pressupostos teóricos da Geolinguística e da Sociolinguística variacionista, cujo produto é um Questionário Semântico-Lexical QSL, de modelo onomasiológico, dividido por campos semânticos. As bases teóricas da Geolinguística são fornecidas por Brandão (1991), e as da Sociolinguística são embasadas em Tarallo (2004). O aparato cultural e histórico de Maputo é delimitado pelas considerações de Firmino (2006), Gonçalves (1995), e Mondlane (1995). O público alvo para aplicação do inquérito é constituído de sujeitos que estejam cursando ou tenham concluído o ensino superior, identificados como público universitário, com, no mínimo, 10 anos de vida escolar, divididos equitativamente em homens e mulheres de três faixas etárias (18 a 29 anos; 30 a 44 anos; 45 anos ou mais). A partir desta pesquisa será possível identificar peculiaridades intrínsecas ao processo de formação do léxico dos universitários de Maputo, contribuindo, assim, para a descrição e estudo do português falado em Moçambique. / This dissertation aims to describe the lexicon of Portuguese spoken by university students in Maputo, Mozambique.

Poverty in its many guises - poor housing, no employment, indifferent health and hunger is a driving force for scavenging. In most developing countries, the informal recovery of material from waste is a common survival strategy for the poor. In fact, up to 2% of populations in developing countries depend on recovering, re-using and selling waste materials from streets, dumpsite or landfills for their livelihood. The aim of this study was to develop an understanding of the socio-economic conditions affecting the scavengers and scavenging activities at the Hulene dumpsite in Maputo. This study set out to develop a conceptual framework depicting scavenging, its problems and opportunities. This was used to structure the research. The main issues addressed were: • The driving forces of scavenging where poverty is the major factor. • The organization of scavengers and scavenging activities showing that there is no formal organization of scavengers, which leads to exploitation of vulnerable groups. • The reaction from the national and local authorities, with the prevalence of a repressive policy and absence of support. • The gender dimension on scavenging activities; and • The perception of health risks. The findings are that scavenging constitutes a means of livelihood for poor people. These activities respond to the market demand and not to environmental considerations. However, in performing scavenging activities which results in informal recycling and resources recovery, people generate environmental benefits, economic benefits and social benefits. Other findings are that the informal organization of scavengers increases the exploitation and the health risk of scavengers. Thus, organization is a key to the success of scavengers and indirectly to the municipal economy. It is concluded that the framework set out in this thesis is useful in the sense that it illustrates the factors which influence scavenging activities. This framework can be used for further research in similar situations. It is also concluded that prohibition of scavenging activities would have undesirable consequences for the economy of Maputo in particular and of Mozambique in general. Thus, since this activity brings benefits to scavengers and to society, the government should support and stimulate this activity and not persecute those who provide this service. Consequently, as a recommendation, government, local communities and NGOs are called upon to support scavengers. The formation of scavenger co-operatives can promote sustainable grassroots development in this sector of the population. / Thesis (M.Env.Dev.)-Unversity of Natal, Pietermaritzburg, 2001.

This work discusses the dilemma of the Chopi people, who despite having a rich cultural heritage, were marginalized by other people, owing to menial labour they have done, such as the removal of faeces and grave digging for the city of Maputo. There is a contrast between the Chopis who were historically an exceptional people in rural Mozambique and the rejected and excluded people they have become in the city. This study attempts, to revert this situation, through a participative process of research, action and change, and highlights some aspects related to their cultural and religious identity. Contributing factors to their predicament are political, economic, social and religious in nature. My work entails an intense endeavour towards renewing identity regarding their understanding of employment, through theology and mission in a contextual approach. Transformation and the renewal of the values of the Chopi people are crucial towards this end. / Missiology / M.Th. (Missiology-Specialisation in Urban Ministry)
