The use of dc tomography for investigating ion motion in the quadrupole ion trap is discussed. This approach can be used to investigate the helium collisional cooling of ions in the quadrupole ion trap.

Isobaric and isomeric polyatomic ions are resolved for the first time in a quadrupole ion trap. This is achieved using a trap in which the geometry of the instrument can be manipulated under operating conditions. Variation of the [z.sub.o] dimension of the trap allows the chemical mass shifts associated with higher-order field components to be maximized. Resolution of isobaric doublets is illustrated for the molecular ions of nitrobenzene-[d.sub.5] and naphthalene and for the 3-ethoxyaniline and p-nitrotoluene molecular ions. The resolution is shown to be a function of the chemical properties - not the mass/charge ratios - of the isobaric ions by the separation of an isomeric pair, acetophenone and dihydrobenzofuran.

Simple economies of scale dictate the cooperation between firms sharing channels of distribution. Cost reduction is effected in channel sharing through scheduling/synchronization, simplification, scale and repositioning. Channel sharing also allows cooperating companies to hold more effective inventories and develop efficient inventory systems to help keep costs down in terms of physically moving their inventories. Cooperation also helps in speeding response time in customer service, order processing and deliveries., Historically, goods and services have been distributed through networks in which loosely aligned firms have bargained at arm's length, negotiated aggressively over price and other conditions of sale, and otherwise [...]

Delivery terms are an important but often overlooked element of the distribution mix. Delivery terms specify whether the buyer or seller pays the freight, who controls the routing of the freight, and who bears the risk while the freight is in transit. This article presents the results of a study designed to assess the attitudes of buyers toward different aspects of delivery terms. [ABSTRACT FROM AUTHOR]
