This volume serves as an elementary textbook and reference book in sampling methods. The first two chapters provide the basis for the different techniques which are treated in detail in the remaining 11 chapters. Chapters 3-6 deal with basic sampling schemes such as simple random sampling, unequal probability sampling, stratified sampling, and systematic sampling. Chapters 7 and 8 cover ratio, product, and regression estimators, while in Chapters 9-11 other sampling schemes are discussed, such as multiphase, cluster, and multistage sampling. Chapter 12 is devoted to the estimation of the size of mobile populations, and the last chapter considers techniques for dealing with nonresponse and surveys involving confidential data. The material presented uses only elementary algebraic symbols. Formulas appropriate to different sampling strategies have been presented without proofs. Important definitions and algebraic expressions have been placed in boxes to enable quick overviews. Readers should benefit from the many solved examples and exercises included.

While information on the roles and regulation of transporters for all major nutrients and metabolites in plants has increased significantly, a synthesis of this research has been lacking. Based on current research in genomics and proteomics, this book clarifies the identification and characterization of plant membrane and vacuolar transporters. Transporter functions such as mineral nutrition, cell homeostasis, storage and stress responses are examined with a focus on enhancing nutrient use efficiency in crops, and increasing crops’ ability to withstand nutrient stresses and improve nutrient storage.

This volume serves as an elementary textbook and reference book in sampling methods. The first two chapters provide the basis for the different techniques which are treated in detail in the remaining eleven chapters. Chapters 3-6 deal with basic sampling schemes such as simple random sampling, unequal probability sampling, stratified sampling, and systematic sampling. Chapters 7 and 8 cover ratio, product, and regression estimators, while in Chapters 9-11 other sampling schemes are discussed, such as multiphase, cluster, and multistage sampling.

The material presented uses only elementary algebraic symbols. Formulas appropriate to different sampling strategies have been presented without proofs. Important definitions and algebraic expressions have been placed in boxes to enable quick overviews. Readers will benefit from the many solved examples and exercises included.Audience: This fundamental material on sampling methods will be of interest to researchers and graduate students of statistics, business management, economics, social sciences, agriculture, and other relevant fields.
