Creep,particularly when it is required to describe ‘modulus’ for polymers used in load-bearing engineering applications. Consequently, it is helpful to develop an understanding of creep in polymers from the simplest concepts and to understand where these are accurate and where the limitations exist.

Crystalline Polymers,s where the molecules are initially highly entangled. The usual structure is referred to as semi-crystalline in which there are some regular crystals separated by amorphous regions. The study of the arrangement and growth of crystals in their distinctive morphologies is particular to polymeric materials..

hormones respond to changes in the social and physical environment. We first briefly summarize the methods that have been utilized to assess hormone metabolite concentrations and the methodological challenges researchers currently face, both in the field and in the laboratory. We consider initially

Ansarifarcades (1998–2021), during which successive proactive policies have resulted in one of the largest mini-grid portfolios in Sub-Saharan Africa, to which can be added the thousands of individual solar solutions provided by public or private suppliers. The chapter examines how the negotiated implementat

The book takes a historical, contemporary, and projective outlook using case studies from pre- and ongoing electrification communities in non-Western countries such as Ghana, Ken

D. J. Hourston home systems, micro- or mini-grids, are increasingly being used in Africa to help reduce the electricity access gap as well as deal with the limitations of the national grid. After over a decade of the growth of the off-grid solar sector in the continent, the time is ripe to take stock of the secto
