Given the increase in international trading and the significant energy and environmental challenges in ports around the world, there is a need for a greater understanding of the energy demand behaviour at *** move towards electrified rubber-tyred gantry(RTG)cranes is expected to reduce gas emissions and increase energy savings compared to diesel RTG cranes but it will increase electrical energy demand. Electrical load forecasting is a key tool for understanding the energy demand which is usually applied to data with strong regularities and seasonal patterns. However, the highly volatile and stochastic behaviour of the RTG crane demand creates a substantial prediction challenge. This paper is one of the first extensive investigations into short term load forecastsfor electrified RTG crane demand. Options for model inputs are investigated depending on extensive data and correlation analysis. The effect of estimation accuracy of exogenous variables on the forecast accuracy is investigated as well. The models are tested on two different RTG crane data sets that were collected from the Port of Felixstowe in the UK. The results reveal the effectiveness of the forecast models when the estimation of the number of crane moves and container gross weight are accurate.

This study evaluated the expression of defense compounds from the secondary metabolism of Eucalyptus globulus plants, subjected to direct and indirect stimuli by the insect Ctenarytaina eucalypti (blue gum Psyllid). Results showed that defense responses were activated in plants in all tested cases. Were detected and identified thirty-two compounds in the leaves of treated plants, of which five compounds differed with the control, and all are part of the chemical defenses from the plants, three of them were oxygenated monoterpenes (borneol, exo-2-hydroxy cineole and thymol), a aromatic carboxylic acid (benzoic acid) and a quinone (6-acethyl-flaviolin). The plants induced by volatile compounds and by indirect entomological manner, showed its capability to synthesize defensive compounds without a wound that promotes these responses. Were also found some constitutive secondary metabolites over expressed in the different inductions compared with the control.
