The problem of determining K3(n,1), the minimum size of a ternary code of length n and covering radius 1, is called the football pool problem. By construction, it is here Nike Free Tr Fit 3 shown that K3(9,1)⩽1269. A code whose full a...

In this paper, we investigate the existence of multiple positive periodic solutions to a class of functional difference equations. We answer the open problems proposed by Y. Raffoul in [Electron. J. Differential Equations 55 (2002) 1–...

We develop a metric for ratio scales and explore the notion of compatibility of two sets of measurements of a set of objects or properties on a ratio scale. We briefly address Arrow's impossibility theorem. We Nike Free Run 2 maintain t...

A transversely excited CO2 laser has been constructed using a pulse-forming network source. Reliable, stable operation was demonstrated for pulselengths up to 30 μs at a pressure of 0.65 atm. Observations suggest that the discharge run...

The present work describes the evolution of binary copolymerization of a monomer containing an azoic chromophore with styrene. Reactivity ratios have been computed using several methods. The sequential analysis suggests a favourable cas...

The excess second virial coefficient for (1,1,1,2-tetrafluoroethane + propane) has been measured at temperatures of 299.5 K, 313.15 K, 328.15 K, and 343.15 K, using the pressure-change-on-mixing method. The excess enthalpy and unlike-in...

It is proposed that the genesis of extracellular membrane vesicles in Gram-negative bacteria is a result of cell wall turnover. Peptidoglycan turnover Nike Free Run 3 Canada Price would cause a turgor on the outer membrane, causing the ...

The incorporations of acetate-1-14C, cholesterol-4-14C, and cholesterol-26-14C into the jerveratrum and ceveratrum alkaloids were shown in Veratrum grandiflorum Loesen. fil. The biosynthetic activity of veratramine was affected by the c...

A 16-year-old girl presented with bilateral back pain caused by bilateral upper pole ureteropelvic junction obstructions; an extremely rare phenomenon. Bilateral robotically assisted upper pole pyeloplasties were preformed at the same s...

A new pure optical system that makes it possible to transmit a two-dimensional image and its color is presented. This system uses only one high order diffraction grating and a set of silica multimode fibers. A good color (seven componen...
