Crop production is a process of multiple inputs (water and nutrients, etc.), and the relationships between the inputs and crop yield are very complex. This study used a model for data envelopment analysis (DEA) to evaluate the efficiency of irrigation-fertilization schemes for winter wheat in North China. The field experiments were conducted at the Xiaohe Irrigation Experiment Station in Centra...

INTRODUCTION The aim of this study was to compare the efficiency of a sonic device (Vibringe), syringe irrigation, and passive ultrasonic irrigation in the removal of debris from simulated root canal irregularities. METHODS Root canals with 2 standardized grooves in the apical and coronal parts were filled with dentin debris. Three different irrigation procedures were performed with NaOCl (1%...

Irrigated rice cultivation is an important source of greenhouse gas emissions. Among the main gases, there are carbon dioxide, methane, and nitrous oxide, with emission each varying according to management crop, cultivar irrigation management. In this context, present study aimed quantify partial global warming potential (pGWP) measured by CH4 N2O emissions in conventional hybrid cultivars unde...

introduction mild intermittent asthma is common in children and viral infections are responsible for the majority of exacerbations. as leukotrienes are potent inflammatory mediators, some studies have shown that montelukast, a leukotriene receptor antagonist, may be effective on reduction of asthma symptom. to determine whether a short course of montelukast in asthmatic children with common col...

The improvement of irrigation systems in the Nile Delta is one of the most important attempts in Egypt to implement more effective irrigation technology by improving the existing irrigation networks. Demand delivery system in the existing irrigation network is using of mechanical gates structures to automatically divert water from one portion of an agricultural field to another in the desired a...

Triplaris gardneriana Wedd is a deciduous riparian tree occurring in areas with different climatic conditions Brazil, from the rainforest to tropical dry forest. An increase global temperature and drought events can change growth pattern establishment of species. To evaluate effects intermittent on T. seedlings, an experiment was performed using seedlings one month old subjected three water tre...

A field crop irrigation management decision-making system (CropIrri) was developed based on the soil water balance model, crop phenology model, root growth model, crop water production function, and irrigation management model. The irrigation plan is made through predicating of soil water content in root zone and daily crop water requirement using historical and forecasting weather data, measur...

Abstract. Crop yield is reduced by heat and water stress even more when these conditions co-occur. Yet, compound effects of air temperature availability on crop are poorly quantified. Existing models, relying at least partially empirical functions, cannot account for the feedbacks plant traits response to canopy temperature. We developed a fully mechanistic model, coupling energy balances, dete...
