The steel Modular Building Systems (MBSs) that have been influenced by the Light-gauge Steel Frame (LSF) techniques become a prominent culture in industry. However, detrimental behaviour of structural components at high temperatures has elevated risk fatal accidents event fire. Although several research investigations addressed fire performance modular wall systems, floor systems not adequately...

Energy conservation opportunities in closed plant production systems have been widely discussed, however, a comparison of energy-use efficiency (EUE) for different types hydroponic is lacking. This paper compares the EUE two systems, namely nutrient film technique (NFT) and deep-water culture (DWC), within an aquaponics facility. The energy monitored controlled environment using artificial ligh...

Increasing demand for housing is one of the biggest challenges facing world. Affordable a key priority UK government in addressing this challenge, which calls innovative construction methods to address issue fuel poverty at an affordable cost. Timber-based modern are solutions resolve existing crisis while managing climate change. Therefore, paper presents case study “Integra House”, proof conc...

The low-node pinching order at a high-density plant cultivation system (LN&HD) is now widely adopted for increasing tomato yield and fruit quality. LN&HD period spans 70–120 days, employs the use of small amount substrate (low volume), plants are usually topped between first fourth truss. Using in induces root restriction. Increasing extent restriction pots has been quality some advance...

As one of the main and largest components, facades make a determining contribution to sustainability performance whole building. Thus, selecting optimal wall system is key challenge for designers, especially on multi-material facades. To meet requirements (i.e., cost, energy performance, aesthetics, maintainability) determined by stakeholders client, authorities, designers), this selection invo...

Host nutritional variables were evaluated for their effects on the severity of crown and root rot of tomato caused by Fusarium oxysporum f.sp. radicis-lycopersici. Tomato (Lycopersicon esculentum Mill.) seedlings (cv. Bonnie Best) were grown in a pathogeninfested, soilless rockwool system in the greenhouse and were fertilized with a nutrient solution that was amended with macroand microelements...

Hyperhydricity of shoots initiated in vitro, poor shoot extension, inability cultures to maintain good growth over an extended time, and unsuccessful ex vitro rooting have limited the development a commercial scale micropropagation system for hemp ( Cannabis sativa ). We present culture initiation method that prevents hyperhydricity using vented-lid vessels with 0.2-µm pores medium containing a...

High temperature and humidity can be controlled in greenhouses by using mechanical refrigeration cooling system such as air conditioner (AC) warm humid regions. This study aims to evaluate the techno-financial aspects of AC-cooled greenhouse compared evaporative cooled (EV-cooled) winter summer seasons. Two quonset single-span prototype were built Agriculture Experiment Station Sultan Qaboos Un...
