Within the framework of the cubic honeycomb (cubic tessellation) of Euclidean 3-space, we define a quantum system whose states, called quantum knots, represent a closed knotted piece of rope, i.e., represent the particular spatial configuration of a knot tied in a rope in 3-space. This quantum system, called a quantum knot system, is physically implementable in the same sense as Shor’s quantum ...

Adherence index, superoxide and TNF-alpha production in monocytes, with or without tuftsin treatment, were investigated in hepatosplenic schistosomiasis mansoni bearers with splenectomy with or without autologous implantation of spleen tissue. Three groups were evaluated: Healthy volunteers control group (CG) (n=12); Splenectomy with seft auto-transplant AG (n=18) and Splenectomy without auto-t...

Evidence is presented that MHC restriction of foreign transplantation antigens occurs when tolerance is induced. Whereas PVG and F344 rats rendered tolerant at birth with (DA X PVG)F1 and (DA X F344)F1 hybrid bone marrow cells (BMC), respectively, accept ACI skin grafts, presumably because the foreign transplantation antigens of these third party grafts, which are MHC-compatible with DA, are re...

an industrial gas turbine has the characteristic of decreasing output power on hot summer days while electricity demand peaks. steam injection in gas turbines has been used for many years to prevent the loss of performance of gas turbines caused by high ambient temperature. vodoley system is a closed steam injection gas turbine cycle (csigtc), which is known as a self-sufficient in steam produc...

Descriptors in the Abraham equations for all the 209 PCBs have been obtained from literature chromatographic data. The six descriptors suffice for the prediction of water to octanol partitions, and for the prediction of various water to solvent and gas to solvent partitions, solubility in water, and water to micelle partition. For water to octanol, gas to dry octanol, gas to wet octanol, solubi...

Liquid-gas ejector is an energy conversion device capable of flowing air fluid by utilizing water based on the pressure difference between two fluids without using moving parts. This study aims to determine effect changes in nozzle geometry two-phase flow performance liquid-gas ejector. The method used conducting experiment whose stages include: determining parameter, primary rate, and secondar...

This paper addresses the use of the Constrained Direct Iterative Surface Curvature (CDISC) design method in the aircraft design process. A discussion of some of the requirements for practical use of CFD in the design process is followed by a description of different CFD design methods, along with their relative strengths and weaknesses. A detailed description of the CDISC design method highligh...
