Farming system for irrigated crops in the submédio São Francisco region. I. Industrial tomato
Em trabalho realizado no Centro de Pesquisa AgropecuĂĄria do TrĂłpico Semi-Ărido, com a finalidade de formular sistemas de produção mais rentĂĄveis para a cultura do tomate (Lycopersicon esculentum Mill.) industrial, constatou-se que, para os dois sistemas de cultivo confrontados (sistema tradicional e sistema modificado), o custo total de produção foi menor no sistema modificado, tendo ocorrido aumento da produtividade e da receita lĂquida. O emprego da tecnologia gerada pela pesquisa ocasionou uma redução dos custos da ordem de 40%, variando de Cr 75.262,00/ha no sistema modificado. Com a elevação da produtividade e a redução dos custos, a receita lĂquida variou de Cr 393.751,41/ha no modificado. Com isto, a razĂŁo benefĂcio/custo, que foi de Cr 5,23 no sistema modificado.With the objective of defining more lucrative farming systems for the industrial tomato (Lycopersicon esculentum Mill.) crop, the Centro de Pesquisa AgropecuĂĄria do TrĂłpico Semi-Ărido, in the State of Pernambuco, Brazil, has carried out a study comparing two cropping systems: tradicional, which is the farmers technology; and improved, which is the research technology. The total cost was found to be lower in the improved system with an increase in the productivity and net income. The use of the research technology gave a rectuction of 40% in the total cost, varying from Cr 75.262,00 in the improved system, With the increase in the productivity and the cost reduction, the net income varied from Cr 393.751,41/ha in the improved system. Thus, the benefit/cost ratio was Cr 5,23 in the improved system
Alpinia
Species of the genus Alpinia are widely used by the population and have many described biological activities, including activity against insects. In this paper, we describe the bioactivity of the essential oil of two species of Alpinia genus, A. zerumbet and A. vittata, against Rhodnius nasutus, a vector of Chagas disease. The essential oils of these two species were obtained by hydrodistillation and analyzed by GC-MS. The main constituent of A. zerumbet essential oil (OLALPZER) was terpinen-4-ol, which represented 19.7% of the total components identified. In the essential oil of A. vittata (OLALPVIT) the monoterpene ÎČ-pinene (35.3%) was the main constituent. The essential oils and their main constituents were topically applied on R. nasutus fifth-instar nymphs. In the first 10âmin of application, OLALPVIT and OLALPZER at 125âÎŒg/mL provoked 73.3% and 83.3% of mortality, respectively. Terpinen-4-ol at 25âÎŒg/mL and ÎČ-pinene at 44âÎŒg/mL provoked 100% of mortality. The monitoring of resistant insects showed that both essential oils exhibited antifeedant activity. These results suggest the potential use of A. zerumbet and A. vittata essential oils and their major constituents to control R. nasutus population

Eyetracking and Applied Linguistics
Eyetracking has become a powerful tool in scientific research and has finally found its way into disciplines such as applied linguistics and translation studies, paving the way for new insights and challenges in these fields. The aim of the first International Conference on Eyetracking and Applied Linguistics (ICEAL) was to bring together researchers who use eyetracking to empirically answer their research questions. It was intended to bridge the gaps between applied linguistics, translation studies, cognitive science and computational linguistics on the one hand and to further encourage innovative research methodologies and data triangulation on the other hand. These challenges are also addressed in this proceedings volume: While the studies described in the volume deal with a wide range of topics, they all agree on eyetracking as an appropriate methodology in empirical research
