We report temperature measurements for a cylindrical sample of turbulent RayleighBénard convection (RBC) at points in the interior, well away from the thermal boundary layers near the top and bottom of the sample. The aspect ratio was equal to 1.00 and the Prandtl number σ was equal to 4.4 or 5.5. The data are in the range 5× 10 <R< 10, where R is the Rayleigh number. Measurements of the temper...

Let T be an R-tree with a very small action of a free group FN which has dense orbits. Such a tree T or its metric completion T are not locally compact. However, if one adds the Gromov boundary ∂T to T , then there is a coarser observers’ topology on the union T ∪ ∂T , and it is shown here that this union, provided with the observers’ topology, is a compact space b T obs. To any R-tree T as abo...

  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...

Population structure, growth, length-weight relationship and reproduction characteristics of leaping grey mullet (Liza saliens (Risso, 1810) were investigated in Beymelek Lagoon from February 2006 to January 2007.  During the study, a total of 1248 leaping grey mullet were captured by gill- and trammel nets of various mesh sizes. Male to female ratio for leaping grey mullet population in Beymel...

________________________________________________________________________________ Abstract The objective was to determine the growth responses of Black Neck ostrich chicks to different dietary levels of L-carnitine in pre-starter diets. Thirty-two day-old ostrich chicks were randomly divided into four treatments with four replicates, each containing two chicks. All birds received the same basal ...

Oceanic depth profiles of plankton respiration are described by a power function, RCO2 = (RCO2 )0(z/z0) , similar to the vertical carbon flux profile. Furthermore, because both ocean processes are closely related, conceptually and mathematically, each can be calculated from the other. The exponent b, always negative, defines the maximum curvature of the respiration–depth profile and controls th...

“The NURBS Book” [L. Piegl, W. Tiller, The NURBS Book, second edn, Springer, 1997] is very popular in the fields of computer aided geometric design (CAGD) and geometric modeling. In Section 9.5.2 of the book, the well-known problem of the local cubic spline approximation is discussed. The key in local cubic spline approximation is cubic polynomial interpolation. In this short paper, we present ...

OBJECTIVE To determine the variables predicting the change of plasma phosphate over the first 24 hr period in intensive care in patients with acute respiratory failure. METHODS Fifty-seven patients were studied prospectively in a university teaching hospital intensive care unit (ICU). Thirty two patients were classified as having acute respiratory failure and a primary respiratory system diag...
