The article describes the background and the detailed history of computer icons featured in graphical interfaces—complete with visual examples and short descriptions of 21 interfaces (from 1981’s Xerox Star to upcoming BeOS Zeta). There is also a breakdown of various icon properties (such as size, style or number of colours). The article ends with a quick glimpse into the future and a conclusio...

The present study was carried out to estimate genetic variability parameters for some traits such as pods per plant, cell membrane stability, one thousand kernel weight, flowering period, grain filling period, chlorophyll content, relative water content, leaf excised water content, seed per pod and pod length, in 16 winter rapeseed genotypes. Statistical analysis showed significant differences ...

We address the task of entity linking to multiple knowledge bases (KB). In particular, we investigate the use of over one thousand domain-specific KBs derived from Wikia.com collections in conjunction with the Wikipedia collection as a background-knowledge repository. Our system employs a two-step approach: for each document, a supervised model with a large set of features detects whether there...

Two varieties of Pearl millet seeds (Penisetum glaucum) (Ex-Borno and SOSAT C88) were obtained from the Lake Chad Research Institute, Maiduguri-Nigeria and reconditioned to moisture contents ranging from 10% 20% w.b. The reconditioned seeds were then evaluated for dimensions, sphericity, bulk density, solid density, porosity, thousand seed mass, angle of repose and static coefficient of frictio...

atrial fibrillation (AF) is associated with a significant burden of morbidity and increased risk of mortality. Antiarrhythmic drug therapy remains a cornerstone to restore and maintain sinus rhythm for patients with paroxysmal and persistent AF based on current guidelines. However, conventional drugs have limited efficacy, present problematic risks of proarrhythmia and cause significant noncard...

Goal. To determine the influence of plant density and treatment with preparation Retenho® on weight 1000 grains seed yield lines — parental components corn hybrids under irrigation conditions. Methods. The research was carried out using field (determining components), laboratory (weight grains), analytical mathematical-statistical methods. Results. maximum mid-early line DK 247 average at a fac...

The maize very important role in the Brazilian economy because it has a high commercial value, having great production due to its ability adapt different edaphoclimatic conditions. Family farming produces seeds from local varieties, called creole seeds. This type of seed is resistant keeps relevant characteristics left as an inheritance ancestors, who, free charge, performed environmental servi...

As the population increases, more people need to be fed. In order find a physical method that influence corn production, this work is dedicated evaluating impact of pre-sowing red laser irradiation (Zea mays L.) seeds on harvest yield. The aim was analyze radiation seeds, quantity and quality yield, large-scale open field production. It hypothesized at least one treatment could improve crop rad...
