Topping stage of tobacco is a key time for development of agriculture measures to promote the quality of leaves. In order to investigating influence of topping timing and suckericide content on tobacco leaf, a factorial experiment on the basis of RCB design with 3 replications was conducted in 2011 at the Tobacco Research Farm of Isfahan. Treatments were including topping time (T1: t...

The process of topping elicits many responses in the tobacco plant, including an increase in nicotine biosynthesis, and the secondary growth of roots. Some topping responsive miRNAs and genes have been identified in our previous study, but the mechanism of the tobacco response to topping has not yet been fully elucidated. In this study, topping responsive proteins isolated from tobacco roots we...

Production costs could be substantially reduced if the height of fruit trees could be lowered enough to eliminate the need for, or reliance upon, ladders in the orchard. Recent research demonstrates that high yields can be obtained on shorter trees with appropriate management techniques, but vigor control can be a problem. In 2004, selected rows of ‘Arctic Star’ nectarine trees growing in the D...

Over 124,300 heat pipes were installed in vertical support members on the Trans Alaska Pipeline System. Infrared surveys in the early 1980s revealed cold topping on some of these heat pipes. The cold topping was due to an accumulation of non-condensable gases, a by-product of corrosion or chemical dissociation of anhydrous ammonia. In 2000, Alyeska Pipeline Service Company undertook an experime...

The combined cycle gas turbine integrates the Brayton cycle as topping cycle and the steam turbine Rankine cycle as bottoming cycle in order to achieve higher thermal efficiency and proper utilization of energy by minimizing the energy loss to a minimum. In this work, the effect of various operating parameters such as maximum temperature and pressure of Rankine cycle, turbine inlet temperature ...

one of the most important practices in flue-cured tobacco farming is topping and sucker control at the right time. topping cause's development and root growth, drought tolerance, reduce deployment pests, increased synthesis of nicotine. this study was conducted in randomized complete block design (rcbd) with 10 treatments in 3 replications over two years (2008-2009) at tirtash research and educ...

This study aims to present a philosophical and quantitative perspective of propulsion system for large-scale hydrogen-fuelled liquid-hydrogen (LH2) tanker ship. Established methods are used evaluate the design performance an LH2-carrier JAMILA, ship designed with four cylindrical LH2 tanks bearing total capacity ∼280,000 m3 along cargo using boil-off as power fuel. Additionally, is evaluated ba...

Industrial applications that require steam for their end-use generally utilize boilers are typically oversized, citing operations flexibility. Similarly, gas turbine-based power plants corroborate a turbine system may eventually relieve the usable exhaust into atmosphere. This study explores economic and technical feasibility of topping cycle combined heat (CHP) system. It does so by leveraging...
