In the context of growing concerns over climate change and peak oil, biofuels for transport are attracting considerable support from the European Union (EU). However, the sustainability of biofuels is under increasing debate. Furthermore, the complexity of the biofuels industry (involving different resources and feedstock suppliers, different logistics providers and options, a range of technologie
Synthesis of operating procedures for batch plants involves systematic generation of step by step instructions which the operator can implement to manage the batch plant safely and optimally. This is a labor and knowledgeintensive task. It often takes weeks of effort by experts to prepare a clear and error free set of instructions even for a moderately complex plant. If this process is automated,
Using the Cayley-Hamilton theorem and unique solubility of scalar Volterra convolution equations of the second kind, the inverse problem of determining the four time-dependent susceptibility dyadics of a linear, homogeneous, bianisotropic slab from generic scattering data at oblique incidence is shown to be well posed. An explicit formula for the crucial step is given.
Highly excited P and D states in 87 Rb were examined using a two-step excitation procedure. A conventional rf lamp and a CW dye laser were used for the first and second step, respectively. The following results for the magnetic dipole interaction constant a , the electric quadrupole interaction constant b , the Landé g J factor, and the tensor polarizability α 2 were obtained in level-crossing an
This dissertation investigates properties of rotating atomic nuclei. Studies are performed using the cranking model and in the particles + rotor model. Properties studied are energy spectra and electromagnetic transition probabilities. The thesis also investigates the use of different liquid drop models at high spin values and studies the use of the particle + rotor approximation for the descripti
Our previous measurements in the P and D series in 133 Cs have been extended to a number of higher lying levels, populated in a two-step excitation process involving an rf lamp and a CW dye laser. The D states were studied with the level-crossing technique, while the optical-double-resonance method was used for the investigation of the P states. For the magnetic dipole interaction constant a , the
A crack model that considers general normal and shear loading is proposed. It involves elasticity, plasticity and damage and it is thermodynamically based. An essential feature of the model is its consistency with the concepts behind the fictitious crack model.
An upper bound on the effective area and bandwidth product for linearly polarized array antennas is derived. The bound is based on the forward scattering sum rule that relates the antenna properties with the polarizability of the antenna structure. The results are illustrated for a dipole array and a capacitively loaded dipole array with numerical simulations.
Particle-stabilized emulsions, called Pickering emulsions, can be produced by using starch particles. In this work we studied how the properties of the starch particles affect the droplet size and creaming of such emulsions. In the study, various sizes of starch particles were generated by two different methods and used to stabilize Pickering emulsions. Sedimentation according to Stokes’ law was u
Background: Dexmedetomidine is a selective alpha-2 agonist with minimal impact on the haemodynamic profile. It is thought to be safer than morphine or stronger opioids, which are drugs currently used for analgesia and sedation in newborn infants. Dexmedetomidine is increasingly being used in children and infants despite not being licenced for analgesia in this group. Objectives: To determine the o
