Effects Of The Inclusion Of Rice Hull Derived Bio-Oil On Wood Pellet Production, Tyler E. Lowe
Effects Of The Inclusion Of Rice Hull Derived Bio-Oil On Wood Pellet Production, Tyler E. Lowe
Theses and Dissertations
Wood pellet production has become an advancing industry for the sake of reducing greenhouse emissions into the atmosphere especially, in European Union countries. Researchers and industry executives seek new methods and materials to improve the pelletization process. Rice hulls or husks has the potential to aid in wood pelletization as they possess high calorific values. This study focuses on using rice hull derived bio-oil from pyrolysis, which will also decrease ash content, as an additive to aid in the wood pelletization process. Using two groups of rice hull derived bio-oil as an additive in wood pelletization: Group 1 uses heavy …
Economic And Ecosystem Impacts Of Gm Maize In South Africa, Kristiina Ala-Kokko
Economic And Ecosystem Impacts Of Gm Maize In South Africa, Kristiina Ala-Kokko
Graduate Theses and Dissertations
White maize in South Africa is the only staple crop produced on a widespread commercial basis for direct human consumption using genetically modified (GM) cultivars. Using a combined economic and environmental approach, we estimate the total welfare benefits attributable to GM white maize in South Africa for 2001-2018 are $694.7 million. Food security benefits attributable to GM white maize in South Africa also manifest through an average of 4.6 million additional white maize rations annually. To achieve these additional annual rations using conventional hybrid maize, the additional land required would range from 1,088 hectares in 2001 to 217,788 hectares in …
Estimating Irrigation In Rice Fields With A Water Balance Approach, Kristen Trinh
Estimating Irrigation In Rice Fields With A Water Balance Approach, Kristen Trinh
Biological and Agricultural Engineering Undergraduate Honors Theses
Global food production must increase to meet the demand associated with increased population growth, so irrigation water use will continue to rise. Therefore, it is important to monitor water usage particularly when an irrigation flowmeter is unavailable. A field water balance was created for a selection of rice fields in East-central Arkansas under observation in 2018 and 2019. From those, irrigation inputs are deduced from the water balance alone. First, each field had sensors that collected water table level (WTL) data. Next, other water inputs and outputs such as precipitation and evapotranspiration (ET) were collected from two modeled sources. The …
Evaluación De Impacto Ambiental En El Proyecto Red De Huertas Urbanas En Localidad Rafael Uribe Uribe De Bogotá D.C, Andrés Felipe Pinto Arias, René Alejandro Aguilar Díaz
Evaluación De Impacto Ambiental En El Proyecto Red De Huertas Urbanas En Localidad Rafael Uribe Uribe De Bogotá D.C, Andrés Felipe Pinto Arias, René Alejandro Aguilar Díaz
Ingeniería Ambiental y Sanitaria
La siguiente investigación tiene por objeto realizar la evaluación de impacto ambiental EIA de la RED huertas agroecológicas de la localidad de Rafael Uribe Uribe de Bogotá D.C, para esto se inició un marco teórico de las huertas urbanas y agroecológicas en diferentes países de América latina , su incidencia y el debate teórico entre el modelo actual de desarrollo agrícola desarrollado por la revolución verde y el de la propuesta del modelo de desarrollo alternativo agroecológico, en donde se definió que sus principales debates se centran en los impactos negativos que genera por medio de la agricultura industrial e …
