- Description: Abstract: The current study focuses on investigating the effect of milling parameters on the microhardness during dry and flood milling of Ti-6Al-4V. Dry and flood milling were performed while varying spindle speed (120, 150, and 180 rev/min), depth of cut (1, 1.5 and 2 mm), as the feed rate (4.6 mm/min) was kept constant. Subsequent to milling, milled surfaces microhardness were measured and microstructure evolution was analysed using an optical microscope. It was established that the deformation of beta phase increased with increase of spindle speed during dry milling while during flood milling there was no microstructural change associated to the increase of the spindle speed. On the other hand, the hardness increased as result of increase of spindle speed during both dry and flood milling. Flood milling generated a maximum hardness of 338.44 HV at 180 rev/min which is superior to maximum hardness of 336.36 HV produced during dry milling. Dry milling at 1.5 mm depth of cut generated maximum deformation of beta phase while during flood milling maximum deformation was recorded at 2 mm depth of cut. The hardness increased with increment of depth of cut during flood milling while it decreased with increase of depth of cut during dry milling.

- Description: Abstract: Municipal solid waste (MSW) management is not a one-off planning, it is a dynamic evolution and planning has to cater for it. The quantity of MSW generated and composition form the basis for planning and management of MSW. However, for an effective MSW reduction policy to be implemented, generated quantity of MSW is not sufficient alone for policy implementation but more of the variables affecting the generation rate and composition are critical. Without an in-depth understanding of these variables, waste reduction policies may be ineffective and unsuccessful. In this study, we reviewed the impact of these factors on MSW. A case of the City of Johannesburg (CoJ) was studied. Population and gross domestic product (GDP) are the two compelling factors affecting MSW generation. The waste generation per capita is influenced by income level. High income group generate on average 1.91 kg/capita/day, middle income group generates 1.01 kg/capita/day and low income group 0.92 kg/capita/day. This put the CoJ total waste generated at an average of 1.83 million ton/year.

- Description: Abstract: Short and long-term municipal solid waste (MSW) management requires adequate planning. Understanding the relationship among variables that affect MSW generation and predicting MSW based on them is needed for an effective planning. Methodologies to forecast MSW are numerous and have been implemented at different level of data granularity. Lack of data in many African cities and countries has hampered effective waste management plan. The lack of data has mainly been attributed to insufficient budget and lack of capacity to implement such management structure. In this study, we investigated the impact of data quality on forecasting efficiency using advanced prediction techniques. It was observed that the quality of waste related data variables determines the extent of model reliability and prediction accuracy.

- Description: Abstract: This paper reviews the utilization of biogas in spark ignition engines with a view to making a case for it as an efficient substitute fuel for petrol. However, its gaseous nature which accounts for its low volumetric density implies that apart from the basic modification needed to accommodate the fuel, the engine might need further alterations to get the best from this relatively low cost and readily available fuel. Various modes of enhancing performance particularly methane enrichment, prechamber combustion, alteration of ignition parameters, increasing compression ratio and addition of hydrogen to improve performance and emissions were drawn from previous works to validate its efficiency as a viable substitute fuel in SI engines.

- Description: Abstract: Landfills within the City of Johannesburg (CoJ) are running out of airspace. To slow down airspace consumption rate, waste discharged at these landfills must be minimised, and where possible recover useful resources. A multi-criteria decision tool, the Analytical Hierarchy Process (AHP) was employed to appropriate technologies for fruit and vegetables waste discharge at Robinson Deep landfill. The goal of the approach is environmental sustainability. Pairwise comparison of four criteria and four technology alternatives were investigated. Data used were retrieved from a research group and consultations with waste to energy experts. Of the four technology alternatives, anaerobic digestion (AD) is the most preferred. Incineration technology has 49.42% preference to AD because it is perceived to reduce the bulkiness of waste discharged at the landfill. Composting has 25.24% preference to AD and it is believed to encourage home management of waste. Consistency ratio for all pairwise comparison was less than 0.1.

- Description: Humanitarian crisis leave the affected people in need of water, health care, and shelter. In order to promptly and adequately respond to the overwhelming needs of the vulnerable people, both the local and the international community has formed several humanitarian organizations, charged with the responsibility of providing aid and assistance to people affected by crisis, irrespective of their geographical location. Humanitarian organizations require safe passage to carry out their operations; the concept of humanitarian space was developed to ensure this. While preserving humanitarian space in conflict zone is proving challenging to humanitarian organizations because of various factors, it is however clear that the security of aid workers is a major concerns for aid organizations working in areas experiencing social change or armed conflicts. The rates of kidnapping, injuries and deaths of aid workers seems be on the increase, requiring aid agencies to be more security conscious and adopt measures to save guard the lives of their employees. Some measures taken recently by humanitarian organizations include suspending aid when and where the security of their employees is under threat and in some cases withdrawing completely from such environment. Thus, affecting the ability of aid organizations to carry out their mandate and as a result, those who are in dire need of relief and assistance suffer. For there to be an improvement in aid delivery, warring parties should respect the sanctity of humanitarian space and the ethics governing humanitarianism. This paper therefore present a review of humanitarian space and the security of humanitarian aid workers.

- Description: Logistics management has been extensively researched and implemented in the private sector, but gradually gaining traction in the humanitarian sector. Humanitarian organizations, particularly Non-Governmental Organizations (NGOs) are the primary vehicle through which donors channel their contributions but many of these organizations face logistic challenges in effectively getting relief materials to the intended users. The purpose of this paper is to identify the key challenges affecting aid agencies in South Africa. A comparative analysis of the challenges of generic engineering logistics to humanitarian logistics in disaster response and relief support system in South Africa was also conducted. The findings from the research survey shows that there is an awareness of the importance of humanitarian logistics in the sector, but the results also show that only half (50%) of the participants of the survey reported that they have a logistics professional employed in their organization. Furthermore, only 50% of the participants of the survey indicated that their organization has a preparedness plan in place in the event of an emergency. Other challenges identified are: lack of funds; difficulty to obtain real time information and poor knowledge management system. The study also suggests that learning and forging closer ties with private organizations is an effective means of overcoming some of the identified challenges. In comparison to the generic engineering logistics, the humanitarian sector is encouraged to benchmark their operations with similar private sector to improve their services.

In this paper, research was conducted to investigate how logistics and supply chains are implemented in cement factories in Nigeria, identify the problem areas and proffer solutions. The study was conducted by administering well-structured questionnaires. According to the investigation, it was confirmed that most of the investigated companies based their logistical system only on road-link transport system for delivering products to their customers or end-users. Furthermore, the survey revealed that 73% of the respondents prefer to continue with the road-link logistics system. Though there is railway infrastructure in the country but due to research finding, the rail system is obsolete due to negligence and poor maintenance on this logistics system. A new railway infrastructure will have to be put in place for effective and efficient operation; and this is going to be costly for individual company to bear.

- Description: Environmental change is happening everywhere. Turbulent weather patterns - heat waves, rains, snowfalls, hurricanes and stormy rains are becoming extreme in every sense throughout the world. These climatic changes are today a concern of every individual and world leader alike. The burning of oil and other fossil fuels releases carbon dioxide, which rises, blankets the earth and traps heat causing severe changes in weather patterns. Not only do we have climate problems but we are also dealing with a resource depletion issue. The construction industry has a major impact on the environment because 50% of the material resources for construction are taken from nature. The huge consumption of resources by the construction industry has called for sustainable practices in construction. Sustainable supply chain provides economic, social and environmental requirements in material and service flows occurring between suppliers, manufacturers and customers. Sustainable development has taken the centre stage among different countries of the world. During the 1992 Earth Summit in Rio, the governments and other international organizations decided to take useful measures to protect the environment for long term social and economic development. This paper aims at investigating the compliance of the construction industry to environmental regulations. In this paper, the construction industry of Lagos state in Nigeria was used as a case study.
