Independent competition

Aroylbutyric acids react with oxalyl chloride to produce mixtures of open-chain isomers of the chlorides and unsaturated lactones, the latter being formed by dehydrochlorination of the cyclic isomers of the chlorides [86JCS(P2)355]. It was presumed in that paper that the two chloride isomers were formed from the initial acids in two independent competitive reaction pathways. [Pg.263]

Insofar, as the direct measurement of the competition between butadiene and butenes is not possible, butene being a reaction product, it is necessary to run two independent competitive hydrogenation experiments such as butadiene / propene and propene / butene from which it becomes possible to determine adsorption coefficient ratio bdiene/bbutenes- These values are reported in Table 1. [Pg.410]

As referred to above, most of the modules involve the intervention of a third party, the so-called notified bodies. These bodies are designated by Member States as being competent to carry out the certification tasks for which they are notified. As a precondition for their notification they must fulfil the minimum criteria which are set out in the relevant directives. These conditions vary from independence, impartiality and professional integrity, to technical competence, possession of or access to necessary facilities and to liability insurance. Once notified, the Commission publishes a list of all notified bodies in the Official Journal, It is worth noting that there is free competition between notified bodies and that manufacturers can make their own choice from all notified bodies notified within the European Union. [Pg.939]

It may seem, at first sight, paradoxical that a competition reaction carried out under conditions in which the measured rate is independent of the concentration of the aromatic can tell us about the relative reactivities of two aromatics. Obviously, the measured rate has nothing to do with the rate of the product-determining step, and what is important in determining relative reactivities is the ratio of the values of ( 3.2.4) for two compounds. The criteria to be met for a correct application of the competitive method are well understood. ... [Pg.46]

In considering two investments, we shall let option B be a safe investment having a base net present value (NPV)g that is independent of any competition. We shall let option A yield a net present value (NPV) i if no competition exists and (NPV) 9 if competition exists. We shall then let the probabilities of no competition and competition be Pi andp2 respectively. Thenpo must equal (1 —p ). [Pg.828]

Corporate environmentalism is an evolving concept for environmental protection. In this case, business takes a pro-active stance independent of regulatory authorities. This can be in recognition of social responsibilities, but is more successful when compelled by competition in the market place. Thus, a hrm can conscientiously target environmentally aware consumers (through marketing environmentally friendly products or processes) or can be better placed for hnancial support from ethical investment funding bodies. [Pg.90]

In some cases, e.g., the Hg/NaF q interface, Q is charge dependent but concentration independent. Then it is said that there is no specific ionic adsorption. In order to interpret the charge dependence of Q a standard explanation consists in assuming that Q is related to the existence of a solvent monolayer in contact with the wall [16]. From a theoretical point of view this monolayer is postulated as a subsystem coupled with the metal and the solution via electrostatic and non-electrostatic interactions. The specific shape of Q versus a results from the competition between these interactions and the interactions between solvent molecules in the mono-layer. This description of the electrical double layer has been revisited by... [Pg.804]

At room temperature, NiAl deforms almost exclusively by (100) dislocations [4, 9, 10] and the availability of only 3 independent slip systems is thought to be responsible for the limited ductility of polycrystalline NiAl. Only when single crystals are compressed along the (100) direction ( hard orientation), secondary (111) dislocations can be activated [3, 5]. Their mobility appears to be limited by the screw orientation [5] and yield stresses as high as 2 GPa are reported below 50K [5]. However, (110) dislocations are responsible for the increased plasticity in hard oriented crystals above 600K [3, 7]. The competition between (111) and (110) dislocations as secondary slip systems therefore appears to be one of the key issues to explain the observed deformation behaviour of NiAl. [Pg.349]

There are patterns of dose-response curves that preclude Schild analysis. The model of simple competitive antagonism predicts parallel shifts of agonist dose-response curves with no diminution of maxima. If this is not observed it could be because the antagonism is not of the competitive type or some other factor is obscuring the competitive nature of the antagonism. The shapes of dose-response curves can prevent measurement of response-independent... [Pg.106]

Used to estimate system-independent potency of a simple competitive antagonist that produces surmountable antagonism of agonist response. [Pg.212]

Electronic marketplace/E-commerce In addition to the many databases available and person-to-person contacts, E-commerce in plastics has been conducted through suppliers web sites or the dot-commerce independent web sites that link material buyers with sellers in transactions or auction formats. During the year 2000 five plastic producers/suppliers and various elastomer producers/suppliers created a new and important business model of a joint-venture web site. It provides multiple companies to join forces to do business. This is a strategy some observers call competition and others regard as just another form of selling in. an electronic format. Regardless of how it is perceived, the model will help propel e-commerce into the mainstream of processor procurement due to the size and wealth of the companies involved. The plastic model example is the largest online business-to-business site todate. [Pg.415]

In contrast to consecutive reactions, with parallel competitive reactions it is possible to measure not only the initial rate of isolated reactions, but also the initial rate of reactions in a coupled system. This makes it possible to obtain not only the form of the rate equations and the values of the adsorption coefficients, but also the values of the rate constants in two independent ways. For this reason, the study of mutual influencing of the reactions of this type is centered on the analysis of initial rate data of the single and coupled reactions, rather than on the confrontation of data on single reactions with intergal curves, as is usual with consecutive reactions. [Pg.35]
