 While occasional insect pests of cultivated sunflowers may be managed by conventional or reducedrisk insecticides, the cumulative costs and risks of relying on insecticides to suppress perennial or severe pests (common in North America) call for exploration of broader pest management strategies.  Recent research with the sunflower moth (Homoeosoma electellum [Pyralidae]) and banded sunflower...

This study was carried out to determine the effects of actic acid bacterial inoculant on the fermentation and aerobic stability of sunflower silages. Sunflower was harvested at the milk stage. Inoculant-1174 (Pioneer®,USA) was used as homofermentative lactic acid bacterial inoculant. Inoculant was applied 6.00 log10 cfu/g silage levels. Silages with no additive served as controls. After treatme...

We report the optimization of sunflower oil methyl esters (SOME/biodiesel) production via alkaline catalyzed transesterification of crude sunflower oil and subsequent physical and chemical characterization. The optimum conditions elucidated for the methanolysis of sunflower oil were found to be: methanol/sunflower oil molar ratio, 6:1; reaction temperature, 60 1C; and NaOH catalyst concentratio...

This paper presents an overview of a solution for maintaining the knowledge on evolution of ontology in time. Firstly, an overview of requirements for the solution is summarized. Then, theoretical background for temporal reasoning is provided. Finally, based on identified requirements and theoretical information, methods for incorporating temporal information into ontology are discussed.

Article history: Received 29 June 2006 Received in revised form 19 February 2007 Accepted 15 March 2007 Scaling of ecological data can present a challenge firstly because of the large amount of information contained in an ecological data set, and secondly because of the problem of fitting data to models that we want to use to capture structure. We present a measure of similarity between data co...

Goal Oriented Requirements Elicitation Process (GOREP) is used to identify the requirements of software using AND/OR graph. Requirements elicitation plays an important role for the identification of software's functional and non-functional requirements. The objective of this paper is twofold; firstly, we classify different requirements elicitation techniques on the basis of different crite...

Contrary to Lentz et al. (1), I suggested that the sunflower was carried from North America to Europe, not from North America to Mexico. They also misinterpret a number of early documents. In the original Mexican edition of Hernández, Ximénez (2) neither included a drawing of sunflower nor indicated its use by Indians (indios). Hernández called the sunflower chimalacatl and variants, which tran...
