Development Of A Methodology That Couples Satellite Remote Sensing Measurements To Spatial-Temporal Distribution Of Soil Moisture In The Vadose Zone Of The Everglades National Park, Luis G. Perez

FIU Electronic Theses and Dissertations

Spatial-temporal distribution of soil moisture in the vadose zone is an important aspect of the hydrological cycle that plays a fundamental role in water resources management, including modeling of water flow and mass transport. The vadose zone is a critical transfer and storage compartment, which controls the partitioning of energy and mass linked to surface runoff, evapotranspiration and infiltration. This dissertation focuses on integrating hydraulic characterization methods with remote sensing technologies to estimate the soil moisture distribution by modeling the spatial coverage of soil moisture in the horizontal and vertical dimensions with high temporal resolution.

The methodology consists of using …

Variedades De Sorgos Bmr: Una Alternativa Para Producir Forraje, Instituto Nacional De Innovación Y Transferencia En Tecnología Agropecuaria (Inta-Costa Rica), Roberto Tinoco Mora

INTSORMIL Scientific Publications

Nervadura de color café en variedad de sorgo BMR.

Durante el año 2010, el Instituto Nacional de Innovación y Transferencia en Tecnología Agropecuaria (INTA-Costa Rica), conjuntamente con el Programa Colaborativo y de Apoyo a la Investigación del Sorgo, el Mijo y otros Granos (INTSORMIL, CRSP) ubicado en El Salvador. elaboraron un proyecto de investigación para evaluar la adaptación, producción y valor nutritivo de una colección de 15 variedades de sorgo (Sorghum bicolor) para alimentación animal. Las variedades disponían del gen recesivo denominado BMR, siglas en inglés de "Brown mid rib" que significan "vena café" (Figura 1).

Este gen tiene la …

Implementing Green Roofs On Movie Theaters And Shopping Centers: Business Cases In Profitable Sustainability, Ryan J. Miller

Pomona Senior Theses

This thesis presents the business case for installing green roofs on movie theaters and shopping centers. These businesses can then derive increased profits from the environmental benefits of reduced energy use and increased stormwater retention. After presenting the basic design and benefits of a green roof, the thesis develops stand-alone business plans for a movie theater and shopping center. The author finds that green roofs are a profitable sustainability solution for the commercial enterprise.

Development Of An Optical Sensor For Real-Time Weed Detection Using Laser Based Spectroscopy, Arie Jacobus Paap

Theses: Doctorates and Masters

The management of weeds in agriculture is a time consuming and expensive activity, including in Australia where the predominant strategy is blanket spraying of herbicides. This approach wastes herbicide by applying it in areas where there are no weeds. Discrimination of different plant species can be performed based on the spectral reflectance of the leaves. This thesis describes the development of a sensor for automatic spot spraying of weeds within crop rows. The sensor records the relative intensity of reflected light in three narrow wavebands using lasers as an illumination source.

A prototype weed sensor which had been previously developed …
