mangrove sediments were collected during wet and dry seasons from nine stations in khamir,laft and natural reservoir mangrove-dense areas of hormozgan province in the south of iran. σ pcbs ranged from 5.33 to 15.5 ng/g dry weight and the dominant congener was no.153. average σ ddts for khamir and laft mangroves were 16.58 ± 1.51 and 18.8 ± 9.98 ng/g dry weight. ddt was more abundant than dde an...

Continuous first-order logic has found interest among model theorists who wish to extend the classical analysis of “algebraic” structures (such as fields, group, and graphs) to various natural classes of complete metric structures (such as probability algebras, Hilbert spaces, and Banach spaces). With research in continuous first-order logic preoccupied with studying the model theory of this fr...

Wireless base station and VDSL transceiver require A/D converter with signal bandwidth more than 10MHz and resolution in the range of 12-14bits. Continuous-time Σ∆ A/D converter has the advantage of possible high signal bandwidth as well as low power consumption compared with discrete time counterpart. In this project, our target is to design a 12MHz-signal bandwidth continuous time Σ∆ A/D conv...

Let be a complex topological algebra with unit 1 and a family of proper closed ideals in . For an arbitrary S⊂ we define a globally defined joint spectrum σ (S)= {(λs)s∈S ∈ CS |∃ I ∈ (s− λs) ∈ I ∀s ∈ S}. We prove that for S generating the spectrum σ (S) can be identified with the setM of continuous multiplicative functionals f on such that ker f ∈ . The relation is given by the formula σ (S)= {...

Some examples of Σ 1 1-universal preorders are presented, in the form of various relations of embeddability between countable coloured total orders. As an application, strengthening a theorem of [7], the Σ 1 1-universality of continuous embeddability for dendrites whose branch points have order 3 is obtained.

This paper gives an insight on how to derive the minimum required specifications both for the anti-aliasing filter (AAF) and the analog-to-digital converter (ADC) in the case of an UMTS receiver. Based on the receiver specifications, we come up with a design plan for both discrete time Σ∆ ADC as well as for a continuous time Σ∆ ADC.

Let X be a locally convex Hausdorff space (briefly, lcHs) and L(X) denote the space of all continuous linear operators of X into itself. The space L(X) is denoted by Ls(X) when it is equipped with the topology of pointwise convergence in X (i.e. the strong operator topology). By a spectral measure in X is meant a σ-additive map P : Σ → Ls(X), defined on a σ-algebra Σ of subsets of some set Ω, w...

and Applied Analysis 3 Definition 4. Let X be a Banach space and ΩX the bounded set ofX. The Kuratowski’s measure of noncompactness is the map α : ΩX → [0,∞) defined by α (D) = inf {d > 0 : D ⊆ n ⋃ i=1 Di, diam (Di) ≤ d} , (8) hereD ∈ ΩX. One will use the following basic properties of the α measure and Sadovskii’s fixed point theorem here (see [37– 39]). Lemma 5. Let D1 and D2 be two bounded se...

Let Γ0 ⊂ O(2, 1) be a Schottky group, and let Σ = H2/Γ0 be the corresponding hyperbolic surface. Let C(Σ) denote the space of geodesic currents on Σ. The cohomology group H1(Γ0, V) parametrizes equivalence classes of affine deformations Γu of Γ0 acting on an irreducible representation V of O(2, 1). We define a continuous biaffine map C(Σ)×H1(Γ0, V) Ψ −→ R which is linear on the vector space H1(...
