The use of aluminium alloy instead of steel for the structural components of a 32 ton articulated lorry has been examined. The probable manufacturing difficulties have been assessed and shown to be minimal. The savings in weight possible by using aluminium have been calculated from a structural analysis of the cab, tractor chassis and trailer and from this and an assessment of the manufacturing processes the extra cost of manufacturing in aluminium has been determined. A typical case study shows that this extra cost can be easily recovered by utilising the increased load capacity of the vehicle during the first few years of its life.

AbstractPersons with disabilities face substantial barriers that impede their integration and participation in social and economic activities. Households with disabled members may be vulnerable to poverty due to the extra cost of living with a disability. However, there exists a knowledge gap in the magnitude of the extra cost of disabilities in sub Saharan Africa. Using data from a nationally representative household survey, this paper estimates the extra cost of disabilities in Ghana. The paper further examines the welfare effects of households with persons with disabilities. Based on the standard of living approach, we estimate the extra cost to households with a person with disability to be 26% of annual household consumption expenditures. Adjusting for the extra cost of poverty, the incidence of poverty increases from 38.5 to 52.9% amongst households with a disabled member. Our findings suggest the need to improve the efficiency of support programs to persons with disabilities to mitigate the extra costs of disabilities and reduce their vulnerability to poverty. In addition, enhancing access to economic opportunities and social services for persons with disabilities will be imperative to improve their quality of life and dignity.
