Qualidade fisiológica de sementes peletizadas de cubiu (Solanum sessiliflorum Dunal)

The objective of this study was to evaluate the effect of different recovery materials on the physiological quality of cubiu seeds. This was evaluated with three binder materials (manioc starch, inert talc and dolomitic limestone) and two binder polymers (polyvinyl acetate and gum arabic) with a 30% concentration, and artificial dye finishing. The experimental design was completely randomized, in factorial scheme 3 (agglomerates) x 2 (binders), and additional treatment (bare seeds), containing four replicates and experimental units of fifty seeds/pellets. The seeds were evaluated for: yield; seed/pellet diameter; thousand seed weight; number of seeds per pellets; germination; germination speed index; mean germination time, seedling length; fresh and dry mass of the seedling and emergence. In general, pelletizing increased the weight and diameter of the propagation unit. The physical barrier applied to the seeds by the pelletization did not influence the germination, but delayed the germination rate in relation to the bare seeds, and this effect was not observed in seedling emergence. The coating with dolomitic limestone and polyvinyl acetate presented the best results of germination and vigor.Objetivou-se com este trabalho avaliar o efeito de distintos materiais de recobrimento na qualidade fisiológica de sementes de cubiu. Para tanto, foram testados três materiais aglomerantes (fécula de mandioca, talco inerte e calcário dolomítico) e dois polímeros aglutinantes (acetato de polivinila e goma arábica) na concentração de 30%, e, ao final, acabamento com corante artificial. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 3 (aglomerantes) x 2 (aglutinantes), com tratamento controle (sementes nuas), com quatro repetições e cinquenta sementes/péletes por unidade experimental. As sementes foram avaliadas quanto ao: rendimento; diâmetro das sementes/péletes; massa de mil sementes; número de sementes por péletes; germinação; índice de velocidade de germinação; tempo médio de germinação, comprimento da plântula; massa fresca e seca da plântula e emergência. De maneira geral, a peletização aumentou a massa e o diâmetro da unidade de propagação. A barreira física imposta às sementes pela peletização não influenciou na germinação, mas promoveu atraso na velocidade de germinação em relação às sementes nuas, não sendo observado esse efeito na emergência. O recobrimento com calcário dolomítico e acetato de polivinila apresentaram os melhores resultados de germinação e vigor

Berechnung von Attributsgrenzen für Teilkonfigurationen mit JavaSMT

Software product lines are able to describe multiple products sharing a common base of features and are commonly described as feature models. For complex software product lines, automatic analyses are required to ensure validity and to improve the interactive configuration process. Modern SAT solvers are vital components for the validation process of feature models. The increasing variability of software product lines implies the need to use more expressive solvers like SMT solvers. To assist the development of feature modeling tools, we compare SAT and SMT solvers for the automated analysis of feature models. During this thesis, we create an abstract data type to formally define analyses for feature model defects and their explanations. The result shows that SAT solvers are more efficient at detecting the defects, while SMT solvers can find explanations for them multiple times faster. Feature models can be further expanded by attaching attributes to features. Such attributes may contain a numerical value. Additionally, one attribute can be defined for multiple features. In this thesis, we aim to support the interactive configuration process, by providing the range of the sum of values for an attribute. Such ranges depend on the remaining choices in a configuration of the product line. We provide an exact computation using SMT and an approximation using a heuristic. The evaluation results show that an SMT solver is not suitable for supporting interactive configuration. However, the approximated ranges of the provided heuristic were very close to the exact ones
