Doubled haploids (DHs) are powerful tools to reduce the time and costs needed to produce pure lines to be used in breeding programs. DHs are also useful for genetic mapping of complex qualitative traits, to avoid transgenic hemizygotes, for studies of linkage and estimation of recombination fractions, for screening of recessive mutants. These are just some of the advantages that make DH technology one of the most exciting fields of present and future plant biotechnology. All of the DH methods have model species where these technologies have been developed, or that respond every efficiently to their corresponding induction treatment. However, not all the species of economical/agronomical interest respond to these methodologies as they should be in order to obtain DHs on a routine basis. Indeed, many of them are still considered as low-responding or recalcitrant to these treatments, including many of the most important crops worldwide. Although many groups are making significant progresses in the understanding of these intriguing experimental pathways, little is known about the origin, causes and ways to overcome recalcitrancy. It would be very important to shed light on the particularities of recalcitrant species and the special conditions they need to be induced. In parallel, the knowledge gained from the study of basic aspects in model species could also be beneficial to overcome recalcitrancy. In this e-book, we present a compilation of different approaches leading to the generation of DHs in model and in recalcitrant species, and different studies on new and relevant aspects of this process, useful to extract common traits and features, to know better these processes, and eventually, to elucidate how to make DH technology more efficient.

The first nonlinear optical effect was observed in the 19th century by John Kerr. Nonlinear optics, however, started to grow up only after the invention of the laser, when intense light sources became easily available. The seminal studies by Peter Franken and Nicolaas Bloembergen, in the 1960s, paved the way for the development of today’s nonlinear photonics, the field of research that encompasses all the studies, designs, and implementations of nonlinear optical devices that can be used for the generation, communication, and processing of information. This field has attracted significant attention, partly due to the great potential of exploiting the optical nonlinearities of new or advanced materials to induce new phenomena and achieve new functions. According to Clarivate Web of Science, almost 200,000 papers were published that refer to the topic “nonlinear optic*”. Over 36,000 papers were published in the last four years (2015–2018) with the same keyword, and over 17,000 used the keyword “nonlinear photonic*”. The present Special Issue of Micromachines aims at reviewing the current state of the art and presenting perspectives of further development. Fundamental and applicative aspects are considered, with special attention paid to hot topics that may lead to technological and scientific breakthroughs.

Genomic variations and phenotypic diversity are closely linked and form the underlying mechanism for development of many human diseases. This book addresses the methods of detection, analysis, and interpretation of genomic variations in clinically relevant scenarios. If your research or clinical practice involves handling of genomic sequencing data, this book is for you. Topics covered include: methods for identifying genetic diversity, the workflow for analyzing whole exome and whole genome sequencing data, local ancestry deconvolution models, the value of molecular patterns and pattern biomarkers in cancer diagnosis and prognosis, and genotyping and profiling resistance-associated variants of hepatitis C. If your research or clinical practice involves handling of genomic sequencing data, this book is for you.

This new volume in the acclaimed Amsterdam Archaeological Studies series explores the roles of animals in a rural community in the civitas Batavorum in the 1st to 3rd centuries ad. Large-scale excavations of two settlements and a cremation cemetery in Tiel-Passewaaij have yielded an animal bone assemblage of around 30,000 fragments. The study compares data from both the settlements and the cemetery, assessing the role of livestock in the local economy and the production of surplus products for the Roman market. The author also investigates the use of animals in funerary and other rituals. The inclusion of a catalogue of special animal deposits makes it a valuable reference work for animal bone specialists.Voor de kleine plattelandsgemeenschappen in Romeins Nederland vormde vee de basis van de plaatselijke economie en het dagelijks bestaan. Vee leverde voedsel, maar ook mest en trekkracht die nodig was voor de akkerbouw. Een surplus aan dierlijke producten werd geproduceerd voor de Romeinse markt. Daarnaast speelden dieren ook een belangrijke rol in rituele praktijken. Deze studie, die is gebaseerd op een grote hoeveelheid dierlijk bot uit grootschalige archeologische opgravingen in Tiel-Passewaaij, heeft verrassende nieuwe inzichten opgeleverd in zowel de economische als de symbolische aspecten van dieren.

*THIS BOOK WILL SOON BE AVAILABLE AS OPEN ACCESS BOOK* This book is a valuable resource for policymakers and practitioners as it brings insights mainly from developing countries where relatively less research activity takes place. It is also a valuable resource for courses in mathematics education in the teacher education colleges, and departments of education in the sub-Saharan Africa region. In the increasingly global and technological world mathematics is seen as a significant gatekeeper of opportunities for social and economic advancement and mobility. Hence, countries and development agencies in the broader sub-Saharan Africa region are looking towards increasing access to relevant and high-quality secondary education as a lever towards economic development. Policy makers and other key decision makers in education look towards improvement in mathematics teaching and learning as a key focus in education reform. In the East Africa region also a number of initiatives have been taken at the national level in the respective countries to improve the quality of mathematics education. This book provides an in-depth comparative analysis of the developments and issues in mathematics education in Kenya, Tanzania, Rwanda and Uganda, and advances our understanding of the state of secondary mathematics education in East Africa.

The Embodied Child: Readings in Children’s Literature and Culture brings together essays that offer compelling analyses of children’s bodies as they read and are read, as they interact with literature and other cultural artifacts, and as they are constructed in literature and popular culture. The chapters examine the ideology behind the cultural constructions of the child’s body and the impact they have on society, and how the child’s body becomes a carrier of cultural ideology within the cultural imagination. They also consider the portrayal of children’s bodies in terms of the seeming dichotomies between healthy-vs-unhealthy bodies as well as able-bodied-vs-disabled, and examines flesh-and-blood bodies that engage with literary texts and other media. The contributors bring perspectives from anthropology, communication, education, literary criticism, cultural studies, philosophy, physical education, and religious studies. With wide and astute coverage of disparate literary and cultural texts, and lively scholarly discussions in the introductions to the collection and to each section, this book makes a long-needed contribution to discussions of the body and the child.
