Maize Grain

Maize shelling is still a challenge in low developing countries with more efforts required to advance this operation. In Uganda, motorized immobile maize shellers have been fabricated locally to enhance the shelling operation. However, their performance has not elated the farmers. The unsatisfactory performance is a result of these shellers being fabricated by local artisan with finite understanding of the maize grain characteristics and operation factors to optimize maize shelling. In addition, farmers in these countries have a deficiency of power to operate the motorized maize shellers available. Transportation of these motorized maize shellers is also still a challenge and it imposes an extra cost to the farmers hence reducing their profits from maize growing. In this chapter, we reviewed maize shelling process in low developing countries particularly the categories of maize shelling, maize sheller design requirements, use of equations to design sheller parts, modification of the motorized maize shellers and case studies on the mobile maize shellers, comparing them with immobile maize shellers. The study concluded that on addition to other sheller performance attributes, motorized mobile maize shellers can solve transportation challenges associated with motorized immobile maize shellers.

Area Development

The aims of this study were to identify particular cases where area development has not sufficiently taken into account the carrying capacity, and more generally, to identify saturation and capacity overload problems in tourist destinations. Incorporating a series of specific case studies, the study will recall factors and practices which have produced these situations of saturation or overload, with a view to setting forth a basis for a tourist policy in this area. This study focuses in particular on new or planned tourist destinations in developing countries.

High Power Distance

This study examines factors influencing public service career choice in developing countries through case studies and a survey. Based on the results of these case studies and survey, I conclude that job security, public service motivation, social recognition and status, and the opportunity for career development are important determinants in why individuals in developing countries choose a public service career. Bureaucratic power and family-related factors also play a role and reflect the high power distance and collectivist culture of developing countries.

Emerging And Developing Countries

Urban poverty areas (UPA) in the main cities of the emerging and developing countries are representing the product of a chaotic urban-isation process. This process started through the recent decades as a result of the economic reform in many Emerging countries, mainly in Asia, South America, and some cases in Africa such as Egypt and South Africa. Under the umbrella of the term UPA, there are many other terms such as slums, shantytowns and informal urbanism. In this study, the focus is on a special case of UPA which exist in the main cities of the emerging countries and some cases of developing countries. These UPA have some of the slums characteristics, which indicate the low quality of the urban life such as the pollution of the urban environment, the high density of built up area and the lack of social spaces. However, these areas mainly consist of permanent buildings which were built in most cases by the dwellers themselves due to their basic socio-economic needs, also in most of the cases the basic infrastructure are available. The study hypothesis is discussing the possibility of enhancing the quality of urban life in those UPA through a strategy of integral mul-ti approaches based on the potential opportunities of public spaces. In other words, the key to a successful strategy is “integration”, meaning that all approaches, policies, and projects are considered in relation to one another. This includes the using of new approaches such as green infrastructure (GI) through an integration framework with the other prevalent urban approaches such as participatory, towards innova-tively interactive urban communities. An analytical comparative study was done based on qualitative methods by studying various case studies of UPA in main cities of emerging and developing countries that were up-graded through a strategy of integral multi approaches. These rely on the public spaces as a medium for change, as well the using of quantitative and qualitative methods through actual case studies. The results represent lessons from practice. Based on actual cases, the cumulative urban experiences through various selected cases of upgrading UPA showed that the success depends on the using of an integral approach (multi-disciplinary) that relies on livable innovative public spaces. The new approaches such as GI cannot stand alone, but the strategies can be efficient by using integral an multi approach strategy. The cases also showed that public spaces in UPA are cen-ters of the daily socioeconomic activities, which is why these areas can act as arenas for change, towards better quality of urban life.

Particulate matter (PM) is one of the problems faced in environmental science. It has health effects on man and animals in both developed and developing countries. Research and efforts have been on it several years back. Policy statements and efforts have been published. This review paper is an added information on air pollution. In it, efforts were made in discussing these: classification, effects, methodology, case studies and source apportionment. It is hoped that this paper would contribute to existing knowledge on PM.
