Kinetics and Mechanisms in the Ammoxidation of Toluene over a Titania TiO2(B)-Supported Vanadium Oxide Monolayer Catalyst. 1. Selective Reactions

A kinetic investigation of the ammoxidation of toluene was carried out over a TiO,(B)-supported vanadium oxide catalyst with a loading corresponding to a theoretical monolayer. The partial pressures of reactants toluene, oxygen, and ammonia were varied, and rates were measured for the formations of benzaldehyde and benzonitrile. By analysis of the rate dependencies on partial pressures of reactant

Core-excited smoothly terminating band in Xe-114

High-spin states have been studied in neutron-deficient Xe-114(54), populated through the Ni-58(Ni-58,2p) fusion-evaporation reaction at 230 MeV. The Gammasphere gamma-ray spectrometer has been used in conjunction with the Microball charged-particle detector in order to select evaporation residues of interest. The yrast band has been greatly extended to a tentative spin of 52 (h) over bar and show

Lacunar syndromes, Aspects on risk factors, pathophysiology, diagnosis and prognosis.

The aims of the studies in the thesis were; 1.to investigate incidence, risk factors in comparison to non lacunar stroke patients, initial course and long term prognosis in pure motor stroke (PMS) 2.to determine topography and most probable pathogenetic mechanism of lesions in sensorimotor stroke (SMS). 3.to study if diffusion weighted magnetic resonance tomography(DWI) contribute to a more precis

A source of high-velocity white dwarfs

We investigate whether the recently observed population of high-velocity white dwarfs can be derived from a population of binaries residing initially within the thin disc of the Galaxy. In particular, we consider binaries where the primary is sufficiently massive to explode as a Type II supernova. A large fraction of such binaries are broken up when the primary then explodes as a supernova, owing

When is it Feasible to Model Low Discrete Demand by a Normal Distribution?

Inventory control systems used in practice are quite often modeling the lead-time demand by a normal distribution. This may result in considerable errors when the real demand is low and discrete. For such demand, it is usually better to use a discrete demand distribution. However, this will increase the computational effort. A natural question is under what circumstances a normal approximation is

Thomasevangeliet. Med Jesusorden från Oxyrhynchus (P. Oxy. 1, 654, 655). Text med översättning och anmärkningar av Bo Frid. Inledning och kommentar av Jesper Svartvik. Andra, bearbetade och utökade upplagan

This book provides the Swedish-reading audience with the first commentary on the apocryphal Gospel of Thomas. Bo Frid has translated the Coptic text into Swedish; Jesper Svartvik has written an introduction (pp. 11-42) and an extensive commentary on each and one of the 114 logia (pp. 121-301).
