ABSTRACT The city of Nairobi was initially engineered to keep stormwater out of sight and out of mind. Unfortunately, that approach has turned a potential resource into a waste product and created new environmental hazards. Once the rain falls onto the impervious surfaces of the streets, sidewalk, parking lots and rooftops, it picks up any and all... Continue Reading
ABSTRACT Polyethylene terephthalate (PET) bottles are plastic bottles derived from the raw material known as polyethylene terephthalate). The PET bottles are widely used for packaging carbonated drinks, beverages, food items, mineral water. Due to high consumption of PET bottles, trillions of PET bottles are disposed every year through, land... Continue Reading

ABSTRACT The consumptive use of water assures all year round production of groundnut prone to the vagaries of weather and climate. This brought about the need to supply moisture that is naturally available through rainfall. The successful design of any irrigation system requires the knowledge of the consumptive use of water by the crop under... Continue Reading
ABSTRACT Studies were carried out to determine the haematological characteristics of Clarias gariepinus healthy specimens were obtained from Gubi dam. Blood sample ranging between 1.0-1.5ml were taken with the aid of sterilized syringe (21G) inserted by caudal vein puncture. The haematological parameters for each blood specimen were measured using... Continue Reading

ABSTRACT A comparative study was conducted among organic waste materials namely coconut fiber, hair, sawdust and woodchips as crude oil absorbents. Twenty grams of each of these materials were wrapped in a pouch and submerged into two set-ups, Set-up A: Pure Crude Oil and Set-up B: Crude Oil with seawater, for an hour. Amount of oil absorbed was... Continue Reading
ABSTRACT Maize, known in many English-speaking countries as corn, is a grain domesticated by indigenous people in prehistoric times. The Aztecs and Mayans cultivated it in numerous varieties throughout central and southern Mexico, to cook or grind in a process called nixtamalization. The crop spread throughout America and later around the 1250 BC... Continue Reading
