A cofactor is a component part of many enzymes and functions by uniting with another molecule in order to become active. The use of cofactors to supplement the native amino acids of a protein is essential to maintain the chemical capabilities necessary for organisms to survive. This volume focuses on the significant advances of the past decade in identifying and describing new cofactors--either small molecules or those derived posttranslationally.
Savage's history is deep and diverse. It all started in 1852 when a small trading post was established at the mouth of the Credit River where it empties into the Minnesota River.
This open access book’s theme is Teaching mathematics as to be meaningful – foregrounding children’s play and perspectives. It discusses the relation between teachers, children and mathematical content within the context of play with a particular focus on the framing of these relations within this context, which is an important theme in the debate on whether teaching should be integrated with or separated from children’s play. The work further addresses meaningfulness in the learning process, particularly from the child’s perspective. Globally, most guidelines and curricula for early childhood education mention play as one of the key features for young children’s learning. Still, there are quite different views on the definitions of play and in what ways play should become part of children’s learning. The chapters of the book mirror the research topics presented at the fifth POEM conference in May 2022 divided into four sub-themes: Play and learning, Children’s perspectives on mathematics, Teachers’ competencies and Theorizing aspects of early mathematics education.

Currently, agriculture is at a crossroads similar to that experienced at the beginning of the last century. The growing need to supply food to global markets and the incipient climate is expected to jeopardize the current agricultural systems. This situation requires a rethinking of agricultural production systems, and it is clearly necessary to incorporate new tools and agronomic practices that improve efficiency and sustainability. A key factor can be identified in using resources or the competition of crops to resist biotic and abiotic stresses. Plant growth-promoting bacteria (PGPB) are of outstanding utility due to the multiple mechanisms with which they influence plant development. It ...
