One of the most fascinating aspects in the life of birds is their breeding phase, which is intimately tied to the distribution and abundance of food resources in their environment. However, food is not evenly distributed in space and time, and this is thought to have been one of the factors affecting the evolution nesting strategies. The current study includes nest architecture, nest-site selection, clutch size, nestling growth, parental care and breeding strategy etc. During the study nine species of Passeriformes were observed nesting in the area. Two species of weaver birds nest in pendant...

Earthworm's vermicompost is a nutritive organic fertiliser rich in NKP, micronutrients, and beneficial soil microbes. This book discusses and presents data which suggest that the vermicompost of earthworms contributes to an increase in the yield of crops when used as a fertiliser.

Studies indicate that vermi-composting of food and garden wastes by waste-eater earthworms is more efficient over the conventional aerobic systems. This book explores the possibilities of management in this area.

In this experimental investigation, the performance and emission characteristics in dual fuel mode with hydrogen inducted along with air adopting carburetion technique are studied on a direct injection, single cylinder, four-stroke, air-cooled, stationary diesel engine coupled to an electric dynamometer. Results showed that the specific energy consumption reduces. The brake thermal efficiency and NOx increases compared to baseline diesel. Other emissions, such as, hydrocarbon, carbon-di-oxide and carbon monoxide reduces compared to baseline diesel.
