Paperback. Condición: New. This specially curated collection features four reviews of current and key research on supporting cereal production in sub-Saharan Africa.The first chapter reviews how research and development can support smallholder wheat farmers through improving access to resources and services. The chapter considers current obstacles faced by smallholder farmers, including biophysical limitations such as climatic issues, as well as socio-economic limitations such as land availability.The second chapter assesses the importance of increasing the adoption rate of improved maize technologies within smallholder farming households across Africa. The chapter discusses the economic and institutional barriers inhibiting adoption, as well as farmer attitudes to innovation.The third chapter describes the effect of poor soil fertility, drought and weeds on maize yields in West Africa. The chapter considers strategies for mitigating these constraints, including nutrient management using fertilizers, weed management and resistant varieties of maize.The final chapter discusses phosphorus scarcity in areas of West Africa and details the need to improve sorghum breeding to enhance the crop's tolerance to low-phosphorus soil conditions.

Paperback. Condición: New. This collection features five peer-reviewed reviews on rust diseases of cereals.The first chapter provides an overview of the wheat rust pathogen lifecycle and discusses recent integration of basic biological knowledge and genomic-led tools within an epidemiological framework.The second chapter introduces stripe rust and provides an overview of its decimation of crop yields worldwide. The chapter summarises recent advances in identifying stripe rust resistance genes in wheat as a means of controlling disease spread and limiting its economic damage.The third chapter addresses the need for more effective and sustainable control of rust pathogens affecting wheat and barley in the face of increasing regulatory measures against the use of conventional fungicides, as well as the spread of fungicide resistance.The fourth chapter provides an overview of the recent advances in controlling wheat rust, focussing on the role of pathogen and host genetics, host-pathogen interactions, epidemiology and management strategies.The final chapter considers the main rust pathogens affecting sorghum and details the different conditions in which they proliferate, their symptoms and impact on crop yields.

Paperback. Condición: New. Print on Demand. This book details how precision gage blocks are the standard tools used in the manufacturing shop to check micrometers and other measuring instruments, for precise mechanical work, and as distance pieces or size blocks. The author, a physicist, was tasked with finding a method for calibrating these gages that would be more accurate than any that had been previously used. The problem was solved by using the interference of light waves as the standard for the measurements, instead of relying on measurements of the expansion of a mercury column or the turning of a micrometer screw. These optical methods rely on the precise and reproducible measurement of the wavelengths of light thus establishing gage blocks, traceable to the international standard of the meter, as the new standard for length measurement. The author describes the tools and methods used to measure very small distances, including an optical system for testing plane surfaces and parallelism of surfaces and a method for determining the length of a gage by means of light waves. This book chronicles the development of a practical system for the calibration of precision gage blocks using light waves, offering a comprehensive overview of the principles, procedures, and tools employed in the field of precision measurement.
