The duality properties of Peti Nets (PN) are exploiled in order to apply an algorithmfor the calculation of colored S-invaiants of Predicate Transition nets (Pr/T nets) to the calculation of the colored T-invariants.

The main purpose of this study was to examine the impact different phosphorus (P) fertilizers and organic manures alone in combination with Bacillus sp. MN-54 on growth, yield, nutrient uptake, chlorophyll (SPAD value) crude proteins content chickpea. simple manure (SM), processed (PM), single super phosphate (SSP), rock (RP) were applied individually combinations soil pots, chickpea seeds trea...

The feature interaction problem occurs when the addition of a new feature to a system disrupts the existing services and features This paper describes a tabular notation for specifying the functional behavior of features It also describes how four classes of feature interactions can be detected when features are speci ed in this new notation Our goal is to develop a tool that can automatically ...

For investigating the effect of vermicompost (VC) on improving phytoremediation of Pb by sunflower (Helianthus annuus) cultivar Lakumka, a factorial experiment was conducted in the pots containing soil or its mixture with 10% VC, in a greenhouse with controlled condition at 2018. After 3 weeks irrigation with normal water, plants were daily irrigated with high Pb-polluted water (0, 1000, 1500 o...

peppermint (mentha piperita l.), a herbaceous and perennial species whichis produced mainly for the medicine and food. the peppermint plants were initiated from 10 cm-long rhizome cuttings followed by transferring into pots. the 48 h-treated plants with methyl jasmonate (mj) concentrations (0, 0.1, 0.5 mm) were assessed for their total soluble proteins, malondialdehyde (mda), chlorophylls a, b ...

BACKGROUND AND AIMS Root soil penetration and path optimization are fundamental for root development in soil. We describe the influence of soil strength on root elongation rate and diameter, response to gravity, and root-structure tortuosity, estimated by average curvature of primary maize roots. METHODS Soils with different densities (1·5, 1·6, 1·7 g cm-3), particle sizes (sandy loam; coarse...
