The Effect of Lacing Wire on Axial Compressor Stage Performance at Low Speeds

The lacing defence: double blind study of thresholds for detecting addition of ethanol to drinks.

In Britain it is a criminal offence to drive if the driver’s measured ethanol concentration exceeds 35 ìg per 100 ml in breath or 80 mg per 100 ml in blood. Those found guilty are disqualified from driving unless they can give a special reason why this should not happen. Most commonly, a defendant claims a friend has “laced” a drink by adding spirits, so that he or she has unwittingly consumed ...

Effects of different shoe lacing patterns on perceptual variables and dorsal pressure distribution in heel-toe running

Introduction Foot movement in heel-toe running is influenced by various shoe lacing patterns [1]. Different shoe lacing systems and techniques also offer the possibility to improve shoe fit and shoe comfort. The purpose of this study was to investigate the effects of different lacing patterns on dorsal foot pressures during running. Furthermore, perceived comfort and shoe stability ratings were...

Study of the Effects of Lacing Rods Location on Natural Frequencies in Last Stage Blades of a Steam Turbine

In this study, effects of lacing rods location on natural frequencies of last stage of a Steam Turbine Blades (STBs) have been investigated. STBs are critical and important elements in a turbine as well as power plants. One of the most important parameters in turbine blades is lacing rods location. In this paper, first, a three dimensional (3D) scan was used to produce the geometrical model of ...

Four Positive Formulae for Type a Quiver Polynomials

We give four positive formulae for the (equioriented type A) quiver polynomials of Buch and Fulton [BF99]. All four formulae are combinatorial, in the sense that they are expressed in terms of combinatorial objects of certain types: Zelevinsky permutations, lacing diagrams, Young tableaux, and pipe dreams (also known as rc-graphs). Three of our formulae are multiplicity-free and geometric, mean...
