abstract evapotranspiration as one of the most important components of the hydrologic cycle, plays a key role in water resources management, crop yield simulation and irrigation scheduling. therefore, presenting a low cost and precision model is very essential for calculations of hourly eto. although, there are empirical formulas, their performances are not all satisfactory due to the complicat...
Myocardial fatty acid oxidation (FAO) imaging is a noninvasive technique that can measure FAO rates in tissues for research applications in animals and humans, as well as clinical applications in managing patients with metabolic disorders. FAO imaging has great potential in diagnosis and monitoring of patients with ischemic heart disease, cardiomyopathies, myocarditis, acute coronary syndrome, ...
La determinación de la evapotranspiración referencia resulta suma importancia para un adecuado manejo del riego. Esta puede ser determinada por diferentes métodos, entre los cuales se encuentra el tanque evaporÃmetro clase "A", que utiliza coeficiente Kp corregir las disimilitudes evaporación desde una superficie libre agua y dicha referencia. El trabajo desarrolló con objetivo calibrar "...
This study integrated field-level sensor data into the FAO-56 Penman-Monteith algorithm to provide a site-specific estimate of crop evapotranspiration. was carried out at two contrasting sites for pea and bean (Manawatū) barley (Hawke's Bay) crops managed within irrigation management zones, each site, under variable-rate systems in New Zealand. Daily evapotranspiration estimates were calculated...
Background: Globally, irrigation water deficit (IWD) due to saline intrusion and decreased rainfed continues affect coastal cultivation regions (CCRs). Coastal lowland have increasingly frequent intrusion, resulting in the IWD as a part of climate variability. Cu Lao Dung Isle, terrain-low plain Vietanm is facing revenue loss adverse conditions recent years. Methods: The objective this study wa...
The FAO-56 Penman–Monteith (PM) equation is regarded as the most accurate to estimate reference evapotranspiration (ETo). However, it requires a broad range of data that may not be available or reasonable quality. In this study, nine temperature-based methods were assessed for ETo estimation during irrigation at fourteen locations distributed through hot-summer Mediterranean climate region Alen...
Accurate estimation of crop evapotranspiration (ETc) is crucial for effective irrigation and water management. To achieve this, support vector regression (SVR) was applied to estimate the daily ETc spring maize. Random forest (RF) as a data pre-processing technique utilized determine optimal input variables SVR model. Particle swarm optimization (PSO) employed optimize This study used obtained ...
Knowledge of evapotranspiration at various stages plant development allows irrigation management to be more efficiently carried out according the actual crop demand. There are a variety methods that can used determine reference evapotranspiration, and due high variability parameters influencing this phenomenon, it is common have studies compare different evaluate which one has greatest applicab...
We have previously shown that fatty acid oxidation (FAO) is required for AMP-activated protein kinase (PRKA)-induced maturation in vitro. In the present study, we have further investigated the role of this metabolic pathway in hormone-induced meiotic maturation. Incorporating an assay with (3)H-palmitic acid as the substrate, we first examined the effect of PRKA activators on FAO levels. There ...
Alpha melanocyte stimulating hormone (α-MSH) and Forkhead box C2 protein (Foxc2) enhance lipolysis in multiple tissues. However, their relationship in adipose fatty acid oxidation (FAO) remains unclear. Here, we demonstrated that α-MSH and Foxc2 increased palmitate oxidation to CO2 in white (WAT) and brown adipose tissue (BAT). C/EBPβ expression was reduced by α-MSH and Foxc2. FFA level was ele...
