The effect of flow on corrosion behaviour carbon steel under intermittent oil/water wetting was investigated by a newly-modified “alternate cell”, combining with the use potentiostatic polarisation, in-situ visualisation, contact angle measurements and scanning electron microscopy (SEM). time determined formation thin film electrode surface after transition immersion state. A short alternate pe...

in order to evaluate the possibility and compare different irrigation methods in ricecultivation, an experiment was conducted in factorial based randomized complete blockdesign at rice research institute of iran, mazandaran (amol), during 2011. treatments weredifferent irrigation regimes including alternate wet and drying (awd), semi-dry cultivation(sdc), combining shallow water depth with wett...

It is a common misconception that game-based learning is, by its very nature, engaging for the majority of learners. This is not necessarily the case, particularly for learners in Higher Education who may need to be persuaded of the value of learning games. For some learners, games may simply not be perceived as engaging–either in terms of an initial motivation to play or sustained participatio...

In diesem Beitrag wird ein Programm zur effektiven Sicherheitssensibilisierung im Unternehmen entwickelt. Schwerpunkte des Programms liegen auf Bedrohungsszenarien, der Form eines ‚Alternate Reality Game‘ zur Wissensvermittlung und messbaren Erfolgsgrößen. Mithilfe des Programms soll eine dauerhafte Verhaltensänderung erreicht werden.

Soil drying and re-wetting (DRW) occurs at varying frequencies and intensities during crop production, and is deliberately used in water-saving irrigation techniques that aim to enhance crop water use efficiency. Soil drying not only limits root water uptake which can (but not always) perturb shoot water status, but also alters root synthesis of phytohormones and their transport to shoots to re...

Alternate wettting and drying (AWD) systems save water compared with continuoussubmergence (CS) irrigation. However, the reported effect on yield varies widely and detailedcharacterizations of the hydrological conditions of AWD experiments are often lacking so thatgeneralizations are difficult to make. We compared the effects of AWD and CS on crop andwater productivity in rice in the field expe...

Over half of the world’s population depends on rice for its calorie supply, although it consumes highest amount water compared to other major crops. To minimize this excess usage, alternate wetting and drying (AWD) irrigation practice is considered as an efficient technique in which soil intermittently dried during growing period by maintaining yield a flooded system. Continuous AWD may result ...
