Cassava and Soil Fertility in East Africa
ISBN: 9783838353272 / Angielski / Miękka / 180 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. East African farming systems are characterized by high land pressure and relatively poor soils. They may well represent the direction in which many farming systems in Africa will develop. Cassava (Manihot esculenta) is a key component in these systems and an important crop throughout Africa. This book aims to better understand the roles and production constraints of cassava in order to explore opportunities to improve the productivity and sustainability of smallholder farms. Farm surveys in East Africa show that general beliefs about cassava are (half)myths that hinder the potential of...

Effects on Seismic Properties
ISBN: 9783844387759 / Angielski / Miękka / 124 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Two fluid-related sources of seismic attenuation andvelocity dispersion are examined: thermal relaxation, which originates from the contrasted temperaturevariations in the rock-forming minerals and in thesaturating fluid at the passage of the pressure wave;and the liquid-vapor phase transition in partiallysaturated rocks. An analysis of the relaxation timesshows that these processes are relevant in theseismic frequency band and drive the effective fluidcompressibility towards values higher than theunrelaxed values. Under full thermal relaxation between fluid and mineral, the effective...
