the effect of a commercial probiotic (protexin) on growth performance and survival rate in sobaity sparidentex hasta was investigated. 240 fish with average weight of 2.99±0.87g were treated for 10 weeks. this study was carried out in a completely random design with 12 experimental groups, in 4 treatments each with 3 replicates. experimental groups were consisted of four levels of 0.0, 0.5, 1.0...

When a hypersurface (t) evolves with normal velocity equal to its mean curvature plus a forcing term g(x; t); the generalized (viscosity) solution may be \fattened" at some moment when (t) is singular. This phenomenon corresponds to nonuniqueness of codimension-one solutions. A speciic type of geometric singularity occurs if (t) includes two smooth pieces, at the moment t = 0 when the two piece...

Vestibular schwannoma (VS) is the most common tumor in the extra-axial posterior fossa compartment in adults. Growth rate is paramount to decision making regarding treatment and follow up of these tumors. We conducted a comprehensive review of the literature to answer four questions: What percentage of newly diagnosed VS will grow on follow-up? What factors correlate to tumor growth? What is th...

Let β > 1 and let m > β be an integer. Each x ∈ Iβ := [0, m−1 β−1 ] can be represented in the form x = ∞ ∑ k=1 εkβ −k, where εk ∈ {0, 1, . . . , m − 1} for all k (a β-expansion of x). It is known that a.e. x ∈ Iβ has a continuum of distinct β-expansions. In this paper we prove that if β is a Pisot number, then for a.e. x this continuum has one and the same growth rate. We also link this rate to...

This paper examines two related models, which permit analytical investigation, to gain some insights into a relationship between endogenous growth and business cycle. Using two simple models which incorporate Fisher Black’s idea that a significant part of business cycle fluctuations is a consequence of an economy’s choice, we obtained a negative relationship between uncertainty and growth. Henc...

The growth rate and uniformity of Carbon Nano Tubes (CNTs) based on Chemical Vapor Deposition (CVD) technique is investigated by using a numerical model. In this reactor, inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as  carrier gas enters into a horizontal CVD reactor at atmospheric pressure. Based on the gas phase and surface reactions, released carbon...

Let C be a rate (n ? r)=n convolutional code with canonical parity-check matrix H(D), and let w 0 denote the minimum average weight per edge over all nonzero cycles in the state diagram for C. The rate of growth per edge of the minimum distance between two nonmerged codewords is given by the value of w 0. For any code C, we show how to obtain an upper bound on w 0 from the columns of H(D). Inde...

the ongoing study aims at a brief pathology on saving in iran's private sector. the factors effect on saving in private sector have been introduced, including oil revenues, real interest rate of banking long-term deposits, ratio of stocks transactions value to gross national production (gnp), proportion of employed population to total population, inflation rate and gini coefficient during ...
