Two predictive models were developed within a geographic information system using Genetic Algorithm Rule-Set Prediction (GARP) and the growing degree day (GDD)-water budget (WB) concept to predict the distribution and potential risk of visceral leishmaniasis (VL) in the State of Bahia, Brazil. The objective was to define the environmental suitability of the disease as well as to obtain a deeper...

Negative trends in the monthly MODerate resolution Imaging Spectroradiometer (MODIS) Enhanced Vegetation Index (EVI) time-series were found to be widespread in natural (non-cropland) ecosystems of the eastern United States from 2000 to 2010. Four sub-regions were detected with significant declines in summed growing season (May-September) EVI, namely the Upper Great Lakes, the Southern Appalachi...

Generalized Steiner systems GS(2, k, v, g) were first introduced by Etzion and used to construct optimal constant weight codes over an alphabet of size g + 1 with minimum Hamming distance 2k − 3, in which each codeword has length v and weight k. As to the existence of a GS(2, k, v, g), a lot of work has been done for k = 3, while not so much is known for k = 4. The notion k-GDD was first introd...

background and objectives: the most important determining factor in sugar beet root yield is seed quality. seeds with germination percentage are lower; the germination is slow and non-uniform, will produce plants that initial growth is slow. according to various studies indicate that harvest time is an important factor influencing the quality of sugar beet seed. in the early harvest of sugar be...

The chestnut tree is an important forestry species worldwide, as well a valuable food resource. Over recent years, Portugal has shown increasing trend in area, increases production, hinting at the socioeconomic relevance of this agro-forestry species. In study, bioclimatic indices are applied to analyse spatial distribution trees mainland Portugal, namely growing degree days (GDD; 1900–2400 °C)...
