Análisis digital de imágenes como herramienta en el estudio de cambio color de frutos en postcosecha.
Provedor de dados: 32
Autores: Loera Alvarado, Gerardo.
Se desarrollaron dos técnicas basadas en procesamiento de imágenes digitales; una para generar un modelo geométrico tridimensional en CAD y otra para generar una proyección geométrica en tres especies frutales (mango, naranja y pera). Se tomaron cuatro imágenes; una de la cara más ancha (0°) y el resto cada 90°. Los modelos se generaron dividiendo cada imagen en 8, 16 y 32 divisiones. La proyección geométrica se generó con la corrección de curvatura vertical y horizontal mediante el cálculo de la longitud del arco cada uno o dos pixeles. Se evalúo el efecto del tamaño de las imágenes al 50%, 100% y 200%. Se retiró la cubierta de los fruto y digitalizó, posteriormente se calculó el área externa. Se midió el volumen por desplazamiento de agua y en el modelo...

Incremento en el precio del maíz y efectos sobre la oferta de carne de res a nivel de granja.
Provedor de dados: 32
Autores: Hernández Zarco, Alfonso.
La actividad pecuaria es de gran importancia socioeconómica para el país; la ganadería, en específico la producción de carne, es la actividad más diseminada en el sector rural. Se estima que la superficie aprovechada por la ganadería es superior a 110 millones de hectáreas, aproximadamente 60% del terrritorio nacional (SAGARPA, 2000).  En el presente trabajo se estiman los efectos que se tiene sobre las cantidades ofrecidas de carne de res a nivel de granja ante un incremento en el precio del maíz, sorgo y pan. Los incrementos utilizados sobre los precios de los granos fueron del 5%, 10% y 15%, estos son ingredientes básicos en la dieta de bovinos. De igual manera, se realizo un cuestionario verbal con engordadores de Coatlinchan Texcoco edo. de México...

A Comparative Analysis of Surface Areas and Ratio of the Cervical Spinal Cord and the Vertebral Canal at the Same Levels Via MRI on Healthy Individuals
Provedor de dados: 77
Autores: Duman,Fatma; Ziylan,Taner; Kiresi,Demet; Cicekcibasi,Aynur Emine; Büyükmumcu,Mustafa; Duman,Tolga.
The determination of the normal values of the cross-sectional surface areas and ratios of the vertebral canal and the spinal cord on the healthy individuals is of great importance with regards to the fact that it provides convenience for the doctors to make correct pathological diagnosis because of the most suitable treatment. In this study, it has been aimed to determine the respective ratios between the vertebral canal and the spinal cord via measuring their cross-sectional surface areas at the C3­C6 vertebra levels. The study has been implemented on the Magnetic Resonance Images (MRI) of the cervical vertebral column from healthy individuals at the Department of Radiology, Meram Faculty of Medicine, Necmettin Erbakan University. The study has been...

Land Allocation Effects of the Global Ethanol Surge: Predictions from the International FAPRI Model
Provedor de dados: 31
Autores: Fabiosa,   Jacinto F.; Beghin,   John C.; Dong,   Fengxia; Elobeid,   Amani E.; Tokgoz,   Simla; Yu,   Tun-Hsiang (Edward).
We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market, multi-commodity international FAPRI (Food and Agricultural Policy Research Institute) model. The model incorporates the trade-offs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade. We examine land allocation by type of crop, and pasture use for countries growing feedstock for ethanol (corn, sorghum, wheat, sugarcane, and other grains) and major crops competing with feedstock for land resources such as oilseeds. We shock the model with exogenous changes in ethanol demand, first in the United States, then in Brazil, China,...

Is There Supply Distortion In The Green Box? An Acreage Response Approach
Provedor de dados: 31
Autores: Bakhshi,   Samira; Kerr,   William A.
The shift of the farm subsidies toward programs classified as being decoupled income supports in the WTO’s URAA raises the question of their true impact on production and trade.  In this study, we measured the acreage effects of the Canadian whole farm programs under uncertainty. Based on the theoretical discussions regarding the role of the insurance effect in acreage decisions, we extend the theoretical restrictions examined by Chavas and Holt (1990)which enables us to include this effect in our model specification. Hence, we modified the expected utility maximization framework (under the hypothesis that farmers are risk averse) developed by Chavas and Holt (1990) and derived three distinct effects: market effects, the wealth effect, and the insurance...

Evaluating The Budgeting Approach of Operation and Maintenance of Irrigation in Indonesia by Using Analytic Hierarchy Process
Provedor de dados: 111
Autores: Sachro, Sri Sangkawati; Kurniawan, Vittorio; Hadihardaja, Joetata; Hadihardaja, Iwan K.
Currently, the Indonesian government calculates the operation and maintenance (O&amp;M) budget by considering the size of the irrigation-area. The problem is, the O&amp;M cost is not always proportional to the size of the area. In fact, infrastructure (such as irrigation channel and hydraulic structures) could be decisive in determining the amount of the required budget. This study will assess the difference in the O&amp;M cost between the government’s policy and the new approach using AHP method. The new method has been formulated by the observation in West Java so this study will attempt to apply it to the various irrigation-area in Central Java. As for the result, the direct applicatoin of the formula will yield unsatisfying result hence improvisation...

Autores: Hinojosa,Pedro A.
In this work we deal with surfaces immersed in R³ with constant mean curvature and circular boundary. We improve some global estimates for area and volume of such immersions obtained by other authors. We still establish the uniqueness of the spherical cap in some classes of cmc surfaces.
