Download or read book Estrategia Tecnol Gica Sustentable para Deshidratar Frutas Verduras y Legumbres written by Jos V. Ctor Galaviz and published by Palibrio. This book was released on 2012-07 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Debido a que los resultados del análisis de uniformidad de temperatura del deshidratador convencional no fueron los óptimos, se procedió a diseñar y construir un nueva deshidratador con materiales refractarios con la finalidad de uniformizar la temperatura y mejorar los tiempos de proceso. Los materiales refractarios que se utilizaron fueron el vidrio blanco de 6 mm de espesor y una cama de poliuretano (10cm), debido a su bajo coeficiente de conductividad térmica. Se realizó un análisis estadístico en una prueba ANOVA a un nivel de significancia de 0.5%, donde se hizo una comparación de las medias muéstrales y una comparación de las varianzas de cada uno de los tratamientos, el cual se encontró que la construcción del nuevo deshidratador con materiales refractarios tuvo un comportamiento de uniformidad en las temperaturas a un 95% de confianza. Cabe destacar que la temperatura promedio del deshidratador convencional fue de 38.61°C, mientras que con el nuevo deshidratador construido con materiales refractarios se logró incrementar a 57.43°C, destacando que esta temperatura se logró uniformizar en las tres áreas analizadas del deshidratador. Esto significó un incremento de temperatura con respecto al deshidratador solar convencional de un 48.74%

Download or read book Bernardino de Sahagun written by Miguel Leon-Portilla and published by University of Oklahoma Press. This book was released on 2012-09-13 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: He was sent from Spain on a religious crusade to Mexico to “detect the sickness of idolatry,” but Bernardino de Sahagún (c. 1499-1590) instead became the first anthropologist of the New World. The Franciscan monk developed a deep appreciation for Aztec culture and the Nahuatl language. In this biography, Miguel León-Portilla presents the life story of a fascinating man who came to Mexico intent on changing the traditions and cultures he encountered but instead ended up working to preserve them, even at the cost of persecution. Sahagún was responsible for documenting numerous ancient texts and other native testimonies. He persevered in his efforts to study the native Aztecs until he had developed his own research methodology, becoming a pioneer of anthropology. Sahagún formed a school of Nahua scribes and labored with them for more than sixty years to transcribe the pre-conquest language and culture of the Nahuas. His rich legacy, our most comprehensive account of the Aztecs, is contained in his Primeros Memoriales (1561) and Historia General de las Cosas de Nueva España (1577). Near the end of his life at age 91, Sahagún became so protective of the Aztecs that when he died, his former Indian students and many others felt deeply affected. Translated into English by Mauricio J. Mixco, León-Portilla’s absorbing account presents Sahagún as a complex individual–a man of his times yet a pioneer in many ways.

Download or read book Globalizing Citizenship written by Kim Rygiel and published by UBC Press. This book was released on 2011-01-01 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 9/11, national governments in the global North have struggled to govern populations and manage cross-border traffic without building new barriers to trade. What does citizenship mean in an era of heightened tension between global capitalism and the nation-state? Building on Foucault's concept of biopolitics and an examination of national border and detention policies, Rygiel argues that citizenship is becoming a globalizing regime to govern mobility. The new regime is deepening boundaries based on race, class, and gender, and causing Western nations to embrace a more technocratic, depoliticized understanding of citizenship.

Download or read book Application of Bacterial Pigments as Colorant written by Wan Azlina Ahmad and published by Springer Science & Business Media. This book was released on 2011-10-14 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental concerns regarding continuous use of synthetic dyes saw a revival in the demand for natural dyes as natural dyes exhibit better biodegradability and generally have a higher compatibility with the environment. However, one of the limitations on the use of natural dyes or pigments is the low extraction yield factors (a few grams of pigment per kg of dried raw material). Therefore, the exploitation of other biological sources such as fungi, bacteria and cell cultures offers interesting alternative. Microbial pigments such as from bacterial origins offer the advantage in terms of production compared to pigments extracted from vegetables or animals, due to its simple cell and fast culturing technique. This book offers interesting insight into initial works carried out to demonstrate the potential use of bacterial pigment as colorant for various applications.

Download or read book The Soils of Mexico written by Pavel Krasilnikov and published by Springer Science & Business Media. This book was released on 2013-02-12 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico is an extensive country with an extremely complex mosaic of landscapes. The soils of Mexico have still not been completely studied, and there are few publications available on this subject. This book provides a state-of-the-art view on Mexican soils, their geographical distribution, their use and degradation. This is a first attempt to give a systematized characteristic of the soil resources of Mexico. Land resources of the second-biggest economy in Latin America are critical for its sustainable development, and a demand for adequate soil information is high. The information contained within can be used for any soil-related research done in Mexico and in neighboring countries. The book includes detailed characteristics of soils of all the physiographic regions of Mexico with maps, photos and explanatory schemes. The book is based on the experiences of the authors in research and soil survey, as well as on the existent, mainly ‘grey’ literature on Mexican soils. The book is recommended for researchers and university readers, students of all levels and decision-makers, working in the area of soil science, environmental issues, Earth sciences, land management and nature conservation.

Download or read book Tortillas and Tomatoes written by Tanya Basok and published by McGill-Queen's Press - MQUP. This book was released on 2002 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on interviews with Leamington greenhouse growers and migrant Mexican workers, Tanya Basok offers a timely analysis of why the Seasonal Agricultural Workers Program is needed. She argues that while Mexican workers do not necessarily constitute cheap labour for Canadian growers, they are vital for the survival of some agricultural sectors because they are always available for work, even on holidays and weekends, or when exhausted, sick, or injured. Basok exposes the mechanisms that make Mexican seasonal workers unfree and shows that the workers' virtual inability to refuse the employer's demand for their labour is related not only to economic need but to the rigid control exercised by the Mexican Ministry of Labour and Social Planning and Canadian growers over workers' participation in the Canadian guest worker program, as well as the paternalistic relationship between the Mexican harvesters and their Canadian employers.

Download or read book Biomass Utilization written by Wilfred Cote and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume represents the culmination of nearly three years of planning, organizing and carrying out of a NATO Ad vanced Study Institute on Biomass Utilization. The effort was initi ated by Dr. Harry Sobel, then Editor of Biosources Digest, and a steering committee representing the many disciplines that this field brings together. . When the fiscal and logistical details of the original plan could not be worked out, the idea was temporarily suspended. In the spring of 1982, the Renewable Materials Institute of the State University of New York at the College of Environmental Science and Forestry in Syracuse, New York revived the plan. A number of modifications had to be made, including the venue which was changed from the U.S.A. to Portugal. Additional funding beyond the basic support provided by the Scientific Affairs Division of NATO had to be obtained. Ul timately there were supplementary grants from the Foundation for Microbiology and the Anne S. Richardson Fund to assist student participants. The New York State College of Forestry Foundation, Inc. provided major support through the Renewable Ma terials Institute. The ASI was held in Alcabideche, Portugal from September 26 to October 9, 1982. Eighty participants including fifteen principal lecturers were assembled at the Hotel Sintra Estoril for the program that was organized as a comprehensive course on biomass utilization. The main lectures were supplemented by relevant short papers offered by the participants.
