“O agronegócio tem se consolidado como o setor mais dinâmico e próspero da economia brasileira, aumentando, ano após ano, o percentual da sua participação no produto interno bruto (PIB) do país; nos empregos, diretos e indiretos, gerados pelas diversas cadeias produtivas que o compõem; e no valor total das vendas externas do Brasil. Trata-se, também, de um setor que reflete as complexidades brasileiras: inovação, eficiência e alta competitividade (ainda) convivem com falta de infraestrutura, burocracia, problemas fundiários e fome para determinada parcela da população, sem falar nos desafios e enormes oportunidades ambientais ainda não corretamente compreendidas, comunicada...
Gliomas are fatal diseases, but also represent good models for tumor research with the aim to eventually discover new and appropriate therapeutics against this disease. Glioma experimental research models are of help to investigate tumorigenesis (tumor stem cell theory versus "classical" opinions), tumor angiogenesis (since they are highly vascularized) and tumor invasion (since they grow without limits). In addition, they have a very special microenvironment (the brain) and limited tumor stroma cells (mainly microglia and endothelial cells). This book addresses the molecular mechanisms of the various tumor stages, describes the interaction with the tumor microenvironment and furthermore depicts experimental models for Glioma research and future therapeutic concepts. The book is composed and written for Scientists and Medical Doctors in Oncology, Neurosciences and Molecular Biology.
A formação de professores tem permeado muitos debates tanto no campo político como acadêmico. O docente tem que estar sempre atualizado, na sua área de estudo e naquilo que ocorre no mundo como um todo. Sendo assim, o professor tem um grande desafio, por isso, nessa obra será explanada casos práticos e métodos relevantes que possam auxiliar no processo didático pedagógico da formação docente.
Lianas are woody vines that were the focus of intense study by early ecologists, such as Darwin, who devoted an entire book to the natural history of climbing plants. Over the past quarter century, there has been a resurgence in the study of lianas, and liana are again recognized as important components of many forests, particularly in the tropics. The increasing amount of research on lianas has resulted in a fundamentally deeper understanding of liana ecology, evolution, and life-history, as well as the myriad roles lianas play in forest dynamics and functioning. This book provides insight into the ecology and evolution of lianas, their anatomy, physiology, and natural history, their global abundance and distribution, and their wide-ranging effects on the myriad organisms that inhabit tropical and temperate forests.

This book includes selecting the articles accepted for presentation and discussion at WCQR2021, held on January 20th to 22nd, 2021 (Virtual Conference). The World Conference on Qualitative Research (WCQR) is an annual event that aims to bring together researchers, academics and professionals, promoting the sharing and discussion of knowledge, new perspectives, experiences and innovations on Qualitative Research. WCQR2021 featured four main application fields (Education, Health, Social Sciences, and Engineering/Technology) and seven main subjects: Rationale and Paradigms of Qualitative Research; Systematization of Approaches with Qualitative Studies; Qualitative and Mixed Methods Research; Data Analysis Types; Innovative Processes of Qualitative Data Analysis; Qualitative Research in Web Context; Qualitative Analysis with Software Support. The book is a valuable resource for everyone interested in qualitative research, emphasizing Computer-Assisted Qualitative Data Analysis Software (CAQDAS).
