allergic patients during the pollen season. Nasal tissues appear to play a critical role in this rise because levels of IgE to these allergens may be inhibited by intranasal steroids administered during the season.1,2 Sodium chloride nasal irrigation is an old home remedy used for rhinitis relief with a presumably rather simple action: nasal cleansing and secretion removal. Here we have assesse...

Fertigation is herein defined as the application of solid or liquid (fluid) mineral fertilizers via pressurized irrigation systems, thus forming nutrient containing irrigation water. Although the practice of fertigation only started commercially in the mid 20th century, there is evidence that the concept of irrigation with dissolved nutrients was well known in the past. The first reported examp...

BACKGROUND The need for reoperation or wound infection treatments between pulsatile and gravity irrigation are statistically equivalent, however, it is unclear which method maximizes operative efficiency and expeditious irrigation. In this study we set out to determine the differences in irrigation rate between these various treatment methods. METHODS This was an ex-vivo experimental laborato...

to investigate the efficiency of eradicane application, using herbigation as compared with conventional method (spraying), concerning weed biomass and density reduction and change in corn grain yield, a factorial experiment was conducted based on randomized complete block design in 2006 at research fields of university of tehran (karaj). eradicane was applied at 4.5 (labeled rate), 3.15 or 5.85...

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%...

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...

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 low water holding capacity of soilless substrates increases water stress and waste of nutrient solution. irrigation time management can reduce such problems. in this research, responses of hydroponically cultured greenhouse strawberries were evaluated under different irrigation schedules. in first step, plant daily water need was estimated and then delivered to plants through two metho...
