abstract to evaluate the effects of the irrigation termination in different growth stages on yield and its components of autumn’s canola cultivars in isfahan region. an experiment was conducted in 2005-2006 in kabotar abad research station. a split plot layout within a randomized complete block design with tree replication was used. main plots were seven level of the irrigation cut-off time (d1...

Plant materials have been found useful in decontamination of water polluted with phenolic compounds. The detoxification effect is due to peroxidases contained in plant tissue. Enzyme mediated oxidative coupling of phenol is followed by precipitation of the formed polymer and its removal from the aqueous phase. A synthetic wastewater buffered at pH = 7.4 containing 0.9 mM phenol was treated in t...

The paper corrects earlier upper bounds on the size of free-cut elimination. Free-cut elimination allows cut elimination to be carried out in the presence of non-logical axioms. The correction requires that the notion of a free-cut be modified so that a cut formula is anchored provided that all of its introductions are anchored, instead of only requiring that one of its introductions is anchore...

Background: Brucellosis is a world-wide disease, which has a diverse clinical manifestation, and its diagnosis has to be proven by laboratory data. Serum agglutination test (SAT) is the most-widely used test for diagnosing brucellosis. The enzyme linked immunosorbent assay (ELISA) can also determine specific antibody classes against brucella. It is a sensitive, simple and rapid test, which coul...

Free-cut elimination allows cut elimination to be carried out in the presence of non-logical axioms. Formulas in a proof are anchored provided they originate in a non-logical axiom or non-logical inference. This paper corrects and strengthens earlier upper bounds on the size of free-cut elimination. The correction requires that the notion of a free-cut be modified so that a cut formula is ancho...

maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. when this is the case, the price of the product has a critical effect on optimum value of cut-off grade. this paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (npv) of operation. in order to visualize this ...

in this paper, we study an equivalence relation on the set of fuzzysubgroups of an arbitrary group g and give four equivalent conditions each ofwhich characterizes this relation. we demonstrate that with this equivalencerelation each equivalence class constitutes a lattice under the ordering of fuzzy setinclusion. moreover, we study the behavior of these equivalence classes under theaction of a...
