Circumference, decreasing

In the Launch Lab, you observed that a balloons circumference decreased after the balloon was submerged in ice water. Why did this happen After a cool evening, a rubber pool raft can appear partially inflated. During a sunny afternoon, the same raft can appear fully inflated. Why did the appearance of the raft change These questions can be answered by applying a second gas law—Charles s law. 

In addition to supplementation or dietary intake of the xanthophylls, several other modulators that influence the MPOD response of subjects to supplementation with xanthophylls were reported (Mares et al. 2006). Larger waist circumference and the presence of diabetes predicted a decrease of MPOD. In contrast to earlier findings, iris color was not related to MPOD. No dependence of MPOD on age was revealed in this study but this may be because of its lower age limit of 53 years. 

Snelling Koch (Ref 2) patented a Cordeau in which molten TNT was poured into a lead tube. After the tube cooled, it was subjected over its entire circumference to the action of rapidly moving hammers, whereby its length was increased and its diam decreased. By this method the TNT was reduced to a finer state of division and consequently became more sensitive to initiation. Such a Cordeau is reported to be smoother stronger than when the Pb tube is drawn or rolled... 

If the expansion of the circumference is represented by y8 = C2/Aa, it is clear that B and u become smaller if fi becomes larger. When f approaches infinity, u approaches 0. In this case, from the analysis based on Eq. (5.335), Bm must decrease faster than the expansion of 6n2c/f. This requirement can be satisfied if Bm is expressed by... 

When a particle s surface is not uniformly smooth like that of a sphere but has a texture like that of broccoli or catdiflower, the particle is said to be fractal [12]. With the two-dimensional projection of a fractal particle, we find that the perimeter of the particle increases without limit as the size of the ruler used as a measure decreases in length. The circumference, C, estimated with a ruler of size x is proportional to... 

Because the compression characteristics of powders are time-dependent (the exact extent of this dependency depends on the primary modes of deformation), the final tablet properties depend not only on maximum compression forces but also on the rate at which these forces (rate of deformation) are applied and removed. On a rotary tablet press, the rate of deformation is determined by the tangential velocity of the punch and the compression roller diameters. The tangential velocity of the punch is a product of the press speed and the die table circumference (i.e., die table rpm x 3.14 x pitch circle diameter). As the tangential velocity increases, the rates of compression and decompression increase while the overall compression time decreases. The roller diameter affects both the rate of compression and decompression. As the diameter increases, the rates of compression and decompression decrease. 

PCBs. Exposure to PCBs can affect memory and learning ability in adults (Schantz et al., 2001), and there is evidence that exposure in the womb can cause lower birth weight, smaller head circumference, poor motor reflexes, a greater inclination to startle, and neurological, behavioral, and developmental problems in children. Eating PCB-contaminated fish has been associated with decreased fertility. Exposure to PCBs can increase the risk of cancer, immune and endocrine system dysfunction, non-Hodgkin s lymphoma, diabetes, and liver disease.10... 

Plant data indicate that first the inner diameters of the coils increase and the wall thicknesses decrease as the coils are used. Spalling of the inner surfaces is apparently a major factor. The wall thickness sometimes decreased by as much as 30%. Decreases of the wall thickness may however vary from 5% to 30% around the circumference of the coil. Second, the roughness of surface varies greatly with location. Part of these variations likely depends on local overheating (and burner locations) relative to the coil.
