and Applied Analysis 3 By using weaker conditions than in 4, 10 , Karpuz et al. 1 have established oscillation criteria for differential equation [ x t ∑ i∈R ri t x αi t ]′′ ∑ i∈P pi t x ( βi t ) − ∑ i∈Q qi t x ( γi t ) f t . 1.6 In this paper, we shall continue in the direction to study the oscillatory properties of 1.1 and 1.2 . We establish new oscillation criteria for 1.1 and 1.2 , which ex...

  The aim of the present study was to investigate the age structure, length-weight relationship, sex ratio, sexual maturity stages, growth parameters, natural and fishing mortality coefficients of three species of kilka including common, anchovy and bigeye kilka. The fork length–weight relationship of common, anchovy and bigeye kilka were calculated as W=0.000153 FL2.37, W=0.000349 FL2.18 and W...

The population structure of Aphanius mento in the Seyhan Reservoir was studied on the basis of 834 fish specimens (516 males and 318 females) caught on a monthly basisbetween September 2013 and August 2014. Fish were collected using dip nets of tulle with a 1mm mesh size. The maximum age of fish was found to be 4 years for both sexes combined, the 1 year old age group comprised 62.20% of male s...

016101-1 We study the nonconserved coarsening kinetics of a reconstructed semiconductor surface. The domain size evolution is obtained in situ by time-resolved surface x-ray diffraction. The system exhibits four equivalent domain types with two nonequivalent types of domain boundaries. Small domains are prepared by molecular beam epitaxy deposition of one GaAs layer. We find the correlation len...

In this paper we characterize the set of polynomials f ∈ Fq[X] satisfying the following property: there exists a positive integer d such that for any positive integer l ≤ deg(f) there exists t0 in Fqd such that the polynomial f − t0 has an irreducible factor of degree l over Fqd [X]. This result is then used to progress in the last step which is needed to remove the heuristic from one of the qu...

We present e cient parallel algorithms for the modular decomposition and split decomposition of chordal graphs, provided a representation as a collection of subtrees of a tree is known. The running time is logarithmic and the processor number is linear. 0 Introduction By a module we mean a subset V0 of the vertices of a graphG = (V;E) such that all vertices inside V0 have the same neighbors out...

This study was carried out in order to determine some biological characteristics of the fish species Spicara flexuosa, which is distributed on Eastern Black Sea coast, and contribute management picarel all seas our country. Between October 2015 September 2016, 599 samples were obtained examined laboratory. It determined that individuals between ages I-VII 31.22% population male 68.78% female. T...

(2) x∆(t) = G(t, x(s); 0 ≤ s ≤ t) := G(t, x(·)) on a time scale T that is unbounded above with 0 ∈ T, where x ∈ R andG : [0,∞)T× R 7→ R is a is rd-continuous function in t and x with G(t, 0) = 0. Throughout this paper, for each continuous function φ : [0, t0]T 7→ R there exists at least one continuous function x(t) = x(t, t0, φ) on an interval [t0, a]T such that it satisfies (2) for t ∈ [t0, a]...

We show that within conformal gravity an assumption regarding only the sign of the cosmological constant, namely that Λ be negative, is sufficient, no matter what its magnitude, to not only make its contribution to current era cosmology naturally be of order one today, but to even do so in a way which is fully compatible with the recent high z supernovae cosmology data. The recent discovery [1,...
