Shedding angle

The warp yams stored on the beam (Number 1 in Fig. 17.1) are subject to a constant tension and come into surface contact onto the whip roller (Number 2 in Fig. 17.1). The droppers (Number 3 in Fig. 17.1) apply a tension on each warp yam equivalent to the resultant force of their own weight. The warp yams inserted in the eye of each heddle (Number 4 in Fig. 17.1) have a dynamic vertical movement and perpendicular to the fabric plane to form the shed (angle formed between the two warp yam webs). The weft insertion system comes into frictional contact with the two perpendicularly warp yam plies. The warp yams are located into empty spaces, at regular intervals, of the weaving reed (Number 5 in Fig. 17.1). The weft density of the obtained fabric is then driven by the take-up roller speed (Number 6 in Fig. 17.1).

Recent small angle neutron scattering experiments shed uncertainty on the assumption of affine deformation (14-18). There... 

As Re increases further and vortices are shed, the local rate of mass transfer aft of separation should oscillate. Although no measurements have been made for spheres, mass transfer oscillations at the shedding frequency have been observed for cylinders (B9, D6, SI2). At higher Re the forward portion of the sphere approaches boundary layer flow while aft of separation the flow is complex as discussed above. Figure 5.17 shows experimental values of the local Nusselt number Nuj c for heat transfer to air at high Re. The vertical lines on each curve indicate the values of the separation angle. It is clear that the transfer rate at the rear of the sphere increases more rapidly than that at the front and that even at very high Re the minimum Nuj. occurs aft of separation. Also shown in Fig. 5.17 is the thin concentration boundary layer... 

The comparison of their results with data for the open-chain compounds dimethyldithio-carbonate, (CH3S)2C=0 (14)102 and dimethyltrithiocarbonate (CH3S)2C=S (15)103 sheds light on the influence of cyclation on the structure and orbital interactions of thiocarbonyl compounds. A particularly important feature is the decrease in C=0 and C=S bond lengths upon cyclation. This follows from the reduction of the S—C(sp2)—S angles... 

In common with all angle-resolved cross sections, the differential positro-nium formation cross section, daPs/dtt, contains more information than its integrated counterpart. In particular, it sheds light on the dynamics and detailed mechanisms involved in this unique capture process. This is apparent at the higher kinetic energies, where striking effects related...
