Perfluorinated chemicals (PFCs) are distributed throughout the environment. In the case of perfluorinated alkyl carboxylates and sulfonates, they can be classified as persistent organic pollutants since they are resistant to environmentally relevant reduction, oxidation, and hydrolytic processes. With this in mind, we report on the reductive defluorination of perfluorobutanoate, PFBA (C(3)F(7)C...

BACKGROUND More recently, the association of different risk factors has been described as the metabolic syndrome. Different definitions are being used for the same syndrome. Regardless of the name or classification, it has been well established that a cardiovascular cluster including overweight/obesity, increased blood pressure, and lipid and glucose abnormalities are associated with an increas...

background the aim of this study was to investigate the effect of endurance training accompanied by fasting on lipid profiles and body composition in men. material and methods twenty-six healthy male volunteer subjects participated in the study and were divided into fasting (f) and endurance training+ fasting (et+f) groups. et+f group exercised 3 times per week on treadmill during ramadan month...

In “zero-parameter” or classical Nielsen fixed point theory one studies Fix(f) := {x ∈ X | f(x) = x} where f : X → X is a map. In case X is an oriented compact manifold and f is transverse to the identity map, idX , Fix(f) is a finite set each of whose elements carries a natural sign, ±1, the index of that fixed point. The set Fix(f) is partitioned into Nielsen classes. Adding the indices withi...

We identify the class of Σ1–inductive sets studied by Moschovakis as a set theoretical generalization of the class (1, 3) of the Rabin-Mostowski index hierarchy of alternating automata on infinite trees. That is, we show that every tree language recognized by an alternating automaton of index (1, 3) is Σ1–inductive, and exhibit an automaton whose language is complete in this class w.r.t. contin...

We prove that h?(x) = ??x0 y??1F?(y)dy is regularly varying with index ? [0, ?) if and only V?(x) ?[0,x] y?dF(y) the same index, where > 0, F(x) a distribution function of nonnegative random variable, F?(x) 1?F(x). This contains at ?= 1 result Rogozin [8] on relative stability, 2 new, equivalent characterization domain attraction normal law. For 0 our implies recent conjecture by Seneta [9].

In [1], by using Fredholm index we developed a version of Quillen’s geometric cobordism theory for infinite dimensional Hilbert manifolds. This cobordism theory has a graded group structure under topological union operation and has push-forward maps for complex orientable Fredholm maps. In [19], by using Quinn’s Transversality Theorem [23], it has been shown that this cobordism theory has a gra...

the dmf index of 2000 school children (1000 boys, 1000 girls) 10 to 15 years old is reported. cases were selected randomly among the school children of different schools, situated in various economic zones of isfahan city. almost 50000 permanent teeth have been examined for healthy, decayed (d), missed (m), and filled (f), and recorded as the dmf index. the mean dmf index of boys and girls unde...

A classical theorem of Kuratowski says that every Baire one function on a Gδ subspace of a Polish (= separable completely metrizable) space X can be extended to a Baire one function on X. Kechris and Louveau introduced a finer gradation of Baire one functions into small Baire classes. A Baire one function f is assigned into a class in this heirarchy depending on its oscillation index β(f). We p...
