Seasonal variability of rainfall and thunderstorm in Guinea over the period 1981 to 2010

Republic of Guinea is one of the West African countries which share form a border with the southern part of the Sahel. It is located in the tropical area where the convective systems activities are intense with strong rainfall. Our results on Standardized Precipitation Index are coherent with the Sahel drought during the 1970s, and a recovery period of rainfall since the last years. The Standardized Thunderstorms Index...

Solid waste management in urban communities in Ghana: A case study of the Kumasi metropolis

Globally, solid waste management has in recent times attracted massive attention, and one of the commonly cited areas is the sprawling cities and urban communities, where plastics and other solid waste have become major management challenge. In Ghana, solid waste management has become a major problem, particularly in urban settlements. The overall objective of the study was to investigate the key factors that underlie...

Household perception and willingness to pay for improved waste management service in Mamfe, Cameroon

Lack of financial resources and public participation are major factors that constrain solid waste management in many towns in developing countries. This study sought to determine the willingness to pay (WTP) and the perception of the inhabitants of Mamfe, Cameroon for an improved solid waste management system. A total of 371 households were interviewed and data analysis to identify the determinants of WTP values was...

Non-linear equilibrium and kinetic study of the adsorption of 2,4-dinitrophenol from aqueous solution using activated carbon derived from a olives stones and cotton cake

Olives stones and cotton cakes have been investigated as a cheap and available precursor used for the production of novel carbon using potassium hydroxide as chemical activating agent with 2:1 impregnation ratio at 1.5 M KOH. Carbonization was performed at 450°C for one hour. The activated carbons NOK and MK3 were characterized by Iodine Number, Fourier Transform Infrared (FTIR) spectroscopy, EDX Analysis, Scanning...
