Sturgeons are considered living fossils, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats.

This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the Southern Europe autochthonous species such as Acipenser nacarii and Acipenser sturio that share geographical distribution. Other relevant species (such as Huso huso, A. oxyrhinchus, A. ruthenus, A. stellatus) and areas (Germany, Russia, North America) are also considered. The contents are organised in three sections: Taxonomy and Biogeography (including the morphological and genetic analyses that clarify the taxonomy and phylogeny of sturgeons, focused on those from Southern Europe), Biology and Aquaculture (where several aspects of the developmental biology, feeding, and reproduction are considered in relation to the improvement of sturgeon farming), and Recovery and Conservation (that collates and analyses different recovery research actions, the ecology of the rivers for restoration as well as the problems related to the trade of caviar)."

This graduate text, based on years of teaching experience, is intended for first or second year graduate students in pure mathematics. The main goal of the text is to show how the computer can be used as a tool for research in number theory through numerical experimentation. The book contains many examples of experiments in binary quadratic forms, zeta functions of varieties over finite fields, elementary class field theory, elliptic units, modular forms, along with exercises and selected solutions. Sample programs are written in GP, the scripting language for the computational package PARI, and are available for download from the author's website.

General approaches to multiculturalism run the risk of overlooking an increasingly diverse student population that deserves special consideration and attention: students from immigrant backgrounds whose families toil the fields in order to provide better educational opportunities for their children. This book's purpose is to guide educators to think deeply about their roles and responsibilities in the education of children of farmworker families in our nation's schools. Readers will view their classrooms, schools, districts, and the migrant programs they lead in a broad and inclusive manner through the lens of cultural proficiency. The initial steps when embracing cultural proficiency entails thinking reflectively about one's own values and behaviors and the school's policies and practices toward children of farmworker families. Cultivating a willingness, openness and commitment to meeting the challenges and opportunities of this often-invisible aspect of diversity is an important first step for the development of effective educational practices for migrant students and their families. The cultural proficiency framework can inform staff development models for working effectively with migrant students and their families.

El ministerio de capellania es algo muy cercano al corazon de Jesus. Lo vemos en el libro de Mateo capitulo 25:35-36, "Porque tuve hambre, me disteis de comer; tuve sed, y me disteis de beber; fui forastero, y me recogisteis; estuve desnudo, y me cubristeis; enfermo, y me visitasteis; en la carcel, y venisteis a mi."Si desea ejercer un ministerio en la Capellania se puede comunicar con las oficinas de LACA Internacional al 718-842-8555 o podra visitor la pagina de web al www.lacasny.com. El Obisbo Fernando Rodriguez es Presidente de la asiociacion LACA Internacional y LACA State of New York. Es Obispo de el consilio Asamblea de Iglesia Luz en las Tinieblas y pastor de la Iglesia Cristiana Un Camino al Cielo localizado en el Bronx, NY. El Obispo Rodriguez a viajado a siete paises y venti-un estados abriendo capitulos de capellania y educando el cuerpo de Cristo en este ministerio. El Obispo Rodriguez y su esposa Rev. Joselyn Rodriguez tienen dos hijos Isaiahs F. Rodriguez y Seth F. Rodriguez y una hija que Dios nos a permitido adoptar, Anais Liriano. Dios hasido bueno con el y lo a bendecido de gran manera con una linda familia y un bello hogar.

In an era of crescent cultural globalization, cultures originally from south of the U.S. border are fighting to stay alive inside the classrooms of compulsory educational institutions. Day after day students in these settings are suffering the effects of a cultural McDonalization. These effects pollute their skills as well as their vernacular voices. Social sciences are created neglecting what students and parents bring in the form of a primeval culture. Hence, history is explained in an archaic context, nation-state model, perhaps valid for the nineteenth century but entirely dmod for the current social configuration. This critical (auto)-ethnographic research searches to answer these questions by hearing the vernacular voices that are empowered by the funds of knowledge within each barriohood and are prepared to give rise to a zone of cultural comfort (ZCe. In such zone, Latin-American cultures and the mainstream culture illuminate each other. After more than ten years of learning and teaching in the United States, tha author has come to realize that California has the optimal scenario within public schools to create a model of communicative actions.
