abstract today, greenhouses are used for controlling different climacterics parameters, specially light and temperatures on agricultural productions. the most part of productions is vegetables production in traditional greenhouses (tg) and unfortunately productions quality and quantity in greenhouses is lower than modern (mg) ones. this experiment studies the effects of different climates of tw...

In recent years several classic halls for chamber music were renovated and a few halls of similar capacity were built in Russia. We have selected the most interesting ones and measured their acoustical parameters. Here we are presenting detailed descriptions of five halls in Moscow, Tula, Ufa and Penza in combination with the measurement data. Some of them have long reverberation time and their...

Designed a WSN-based wireless monitoring system for greenhouse environment. The overall structure of the system is introduced. The design and realization of the monitoring node, the gateway node and the upper computer system are respectively described. Through the practical application in the greenhouse, it is proved that the system comprehensive performance is significantly better than the tra...

This paper offers an approach and a theoretical framework for eliciting emotional speech using actors. The framework is developed by connecting the goal-based model of emotion proposed by Abelson [1], the work of appraisal theorists, and an approach to the actor's technical process widely used in the professional theater and taught in modern conservatories. In doing so, we hope to address some ...

Traditional water-saving irrigation management turns on water pump in a settled interval decided by grower’s experience. The method just saves water on the back of losing yield. In order to result the problem, a kind of greenhouse efficient irrigation management system based on Evapotranspiration has been developed. The system includes greenhouse environmental monitoring subsystem, irrigation a...

Wettability is a major factor in determining whether a material can be effectively and efficiently used as a component in greenhouse substrates. Poor wettability can lead to poor plant growth and development as well as water use inefficiency. This research was designed to test the wettability and hydration efficiency of both traditional and alternative components of substrates under different i...

nitrous oxide (n2o) has significant impact on global warming and leads to the depletion of ozone in the stratosphere. agricultural soil is regarded as a major source of n2o emissions. in recent years, greenhouse grown vegetables have rapidly developed in china. although excessive fertilizer application in greenhouse vegetable production can result in increased n2o emissions, research data on su...
