In this paper, an intelligent control of the greenhouse in the Greenhouse Management Framework (GMF) has been designed for the purpose of increasing the farmer’s profit and promoting the ease of agricultural production. The GMF is divided into Greenhouse Control Engine and Crop Growth Engine. The Greenhouse Control Engine consists of Data Aggregator, Greenhouse Information Storage, and Greenhou...

In greenhouse trials, 21 strains of slow-growing rhizobia were tested for symbiotic effectiveness and ability to nodulate three varieties of cowpea, Vigna unguiculata L. Walp. in two Ultisol subsoil samples, each adjusted to pH 4.6 and pH 6.0-6.2. The results confirmed that cowpea rhizobia contain a large and perhaps continuous variation in symbiotic tolerance of soil acidity. Some strains comb...

Commercial and non-commercial plants face a variety of environmental stressors that often cannot be controlled. In this study, transgenic hybrid poplar (Populus × euramericana 'Guariento') harboring five effector genes (vgb, SacB, JERF36, BtCry3A and OC-I) were subjected to drought, salinity, waterlogging and insect stressors in greenhouse or laboratory conditions. Field trials were also conduc...

BACKGROUND To increase the understanding of the physiological mechanisms by which massage therapy produces health benefits such as pain relief and anxiety reduction, the relationship between specific elements of massage and physiological outcomes must be addressed. PURPOSE The effects on resting muscular activity of applying varying levels of pressure during massage were investigated. METHO...

Greenhouses are often used for growing flowers, vegetables, fruits, and tobacco plants. Most greenhouse systems still use the manual system in monitoring the temperature and humidity in the greenhouse, a lot of problems can occur not for worker but also affected production rate because the temperature and humidity of the greenhouse must be constantly monitored to ensure optimal conditions. The ...

Understanding factors that affect the context dependency of species interactions has been identified as a critical research area in ecology. The presence of symbionts in host plants can be an important factor influencing the outcome of plant-insect interactions. Similarly, herbivore identity can alter the outcome of plant-symbiont interactions. Symbiotic foliar fungal endophytes confer resistan...

Plant associated bacteria with plant growth promotion (PGP) properties have been proposed for use as environmentally friendly biofertilizers for sustainable agriculture; however, analysis of their efficacy in the field is often limited. In this study, greenhouse and field trials were carried out using individual endophytic Pseudomonas fluorescens strains, the well characterized rhizospheric P. ...

We assess the roles of long-lived greenhouse gases and ozone depletion in driving meridional surface pressure gradients in the southern extratropics; these gradients are a defining feature of the Southern Annular Mode. Stratospheric ozone depletion is thought to have caused a strengthening of this mode during summer, with increasing long-lived greenhouse gases playing a secondary role. Using a ...

This paper deals with the modelling and simulation of greenhouse climate. The obtaining of greenhouse production models (climate, crop development, etc.) is a subject of large interest nowadays, as these models can be used for simulation, control and production optimization purposes. A greenhouse constitutes a complex dynamical system, which is described in this paper using the object-oriented ...

This paper reviews the greenhouse gas emissions of prefabrication elements for residential development in Hong Kong. Prefabrication becomes a common practice in residential development in Hong Kong and is considered as a green approach. In Hong Kong, prefabrication took place at factories in Pearl River Delta. Although prefabrication reduces construction wastage, it might generate more greenhou...
