We propose a new negation rule for logic programming which derives existentially closed negative literals, and we de ne a version of completion for which this rule is sound and complete. The rule is called \Negation As Instantiation" (NAI). According to it, a negated atom succeeds whenever all the branches of the SLD-tree for the atom either fail or instantiate the atom. The set of the atoms wh...
abstract this quasi-experimental study was aimed at examining the impact of storyline complexity on the grammatical accuracy and complexity of advanced and intermediate efl learners. a total of 65 advanced and intermediate efl learners were selected from iran language institute (ili). an intact group including 35 intermediate participants and another intact group with 30 advanced participants ...
Efficient seed germination and rapid and uniform seedling emergence are important in commercial agriculture. Therefore, the use of strategies to improve germination and seedling establishment is necessary for increasing productivity. Hydropriming has been suggested as a simple pre-germination strategy to improve seed performance. In this study, the effects of different durations of hydropriming...
Most commercial apple orchards are established on either Marubakaido (Malus prunifolia Borkh.) (high vigor), M-9 pumila) (low or a combination of both rootstocks through the intergrafting technique. The Geneva® Series were developed as an alternative to modernization. vigor influences anatomical xylem formation and, therefore, canopy cultivar’s hydraulic conductivity. When affected by embolism,...
A sound and complete semantics is given for sequential, depth-rst logic programming with a version of negation as failure. The semantics is logical in the sense that it is built up only from valuation functions (multi-valued logic interpretations in the style of Fitting and Kunen) and logically-motivated equivalence relations between formulas. The notion of predicate folding and unfolding with ...
The objectives of this study were to assess the risk associated with proportion Brahman inheritance, cow age, dystocia, and birth date weather conditions on calf vigor at birth (n = 3,253) and preweaning mortality (n = 3,631), and to estimate heritabilities for these traits. Calves that had poor vigor at birth and calves that died before weaning were coded 1, and those that had adequate birth v...
A laboratory research carried out to evaluate the effect of drought stress on germination characteristics in two 'Indian' and 'Isfahanian' populations of Fenugreek. This experiment performed in a factorial experiment based on a completely randomized design with three replicates. Four levels of drought stress applied by using polyethylene glycol 6000. Percentage of germination, germination rate,...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
