Les migracions humanes són un fenomen global que s’ha donat en totes les èpoques de la humanitat. A Catalunya, els desplaçaments de la població en l’espai s’han caracteritzat bàsicament per l’alternança entre moviments emigratoris i moviments immigratoris forçats per circumstàncies polítiques, econòmiques o de recerca de treball i millors condicions de vida. Aquest llibre analitza el fenomen que afectà Lleida durant el segle XX i en especial durant l'època del franquisme, el que significà un revulsiu urbanístic i demogràfic sense precedents en la societat lleidatana.
The phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway is an important signaling route that regulates several cell functions. PI3K/AKT/mTOR pathway is a crossroad of cell death and survival, playing a pivotal role in multiple interconnected cell signaling mechanisms implicated in cell metabolism, growth and proliferation, apoptosis, and angiogenesis. Disruptions in the Akt‑regulated pathways and alterations in PTEN expression are associated to Reactive oxygen species (ROS) homeostasis and different types of cancer. Genomic studies have shown that activating mutations in oncogenes as well as inactivating mutations in tumor suppressor gen...
Winner, Presidio La Bahia Award, Sons of the Republic of Texas Built to bring Christianity and European civilization to the northern frontier of New Spain in the seventeenth and eighteenth centuries...secularized and left to decay in the nineteenth century...and restored in the twentieth century, the Spanish missions still standing in Texas are really only shadows of their original selves.

To paint a more complete portrait of...

Over the last three decades, a significant amount of research has sought to relate educational institutions, policies, practices and reforms to social structures and agencies. A number of models have been developed that have become the basis for attempting to understand the complex relation between education and society. At the same time, national and international bodies tasked with improving educational performances seem to be writing in a void, in that there is no rigorous theory guiding their work, and their documents exhibit few references to groups, institutions and forces that can impede or promote their programmes and projects. As a result, the recommendations these bodies provide to...
X-ray astronomy is the prime available window on astrophysical compact objects: black holes, neutron stars and white dwarfs. In this book, prominent experts provide a comprehensive overview of the observations and astrophysics of these objects. This is a valuable reference for graduate students and active researchers.
In The Indian Southwest, 1580-1830, Gary Clayton Anderson argues that, in the face of European conquest and severe droughts that reduced their food sources, Indians in the Southwest proved remarkably adaptable and dynamic.
Mexico and the United States each have a constitution and a federal system of government. This fact has led many historians to assume that the Mexican system of government, established in the 1820s, is an imitation of the U.S. model. But it is not. In this interpretation of the independence movement, Nettie Lee Benson tells the true story of Mexico's transition from colonial status to a federal state. She traces the Mexican government's beginning to events in Spain in 1808–1810, when provincial juntas, or deputations, were established to oppose Napoleon's French rule and govern the country during the Spanish monarch's imprisonment. These provincial deputations proved so popular that ultima...
