SU-8 is the preferred photoresist for development and fabrication of high aspect ratio (HAR) three dimensional patterns. However, processing of SU-8 is a challenging task, especially when the film thickness as well as the aspect ratio is increasing and the size of the features is close to the resolution limit of photolithography. This paper describes process optimization for the fabrication of den

Foundations of buildings and structures are laid with various methods, both deep and shallow foundations. Piling is the most common method of deep foundations while spread footings are often used in shallow foundations, especially in buildings with column frame. An alternative is to use a composite pile foundation where piles and spread footings or piles and a base slab are used to carry the loads

This thesis examines the creative appropriation of Shakespeare in theory and practice. It is based on close readings of King Lear alongside three appropriations of the play in works of fiction by three North American women writers: Jane Smiley, Anne Tyler, and Margaret Atwood. The aim is to demonstrate how a ‘palimpsestic’ reading, i.e. a reading in which the reader oscillates between ‘pre-text’ a

Consider a stationary normal process ξ(t) with mean zero and the covariance function r(t). Properties of the sample functions in the neighborhood of zeros, upcrossings of very high levels, etc. have been studied by, among others, Kac and Slepian, 1959 [4] and Slepian, 1962 [11]. In this paper we shall study the sample functions near local maxima of height u, especially as u → -∞, and mainly use si

The cycloruthenation of 2-phenylimidazole (phim) by [Ru(6-C6H6)(-Cl)Cl]2 in acetonitrile in the presence of NaOH has been carried out. The unstable intermediate [Ru(phim)(MeCN)4]PF6 formed has been converted into the complexes [Ru(phim)(4,4′-Me2bpy)(MeCN)2]PF6 (2) and [Ru(phim)(LL)2]PF6 (3, LL=phen (a), bpy, 4,4′-Me2bpy), which were characterized by the mass-spectrometry, 1H-NMR spectroscopy, UV–v

As the commercial Fe-Mo-oxide catalyst for methanol oxidation to formaldehyde suffers from deactivation by Mo volatilization, alternative catalysts are of interest. Therefore, TiO2-, alpha-Al2O3- and SiO2-supported (Fe)-V-O catalysts were prepared with loading up to 30 μmol of each metal per msq. surface area of the support. The samples were activity tested using a high inlet concentration of meth

This thesis deals primarily with the production of written texts by adults with reading and writing difficulties. Their writing is analysed from three different aspects: error analysis, non-error-oriented text analysis and analysis of the production process. These studies are based on data from on-line recordings of writing. The main question is how the written language production of adults with r

ABSTRACT: BACKGROUND: Long term endurance training is known to increase peak oxygen uptake () and induce morphological changes of the heart such as increased left ventricular mass (LVM). However, the relationship between and the total heart volume (THV), considering both the left and right ventricular dimensions in both males and females, is not completely described. Therefore, the aim of this stu

The cholesterol-lowering effects of oats have led to an increasing interest in them on the food market. Liquid oats has emerged as a new way of consuming oats and has become a commercial product. To produce liquid oats, steam-heated dehulled oat groats are subjected to flaking, wet-milling, enzyme hydrolysis, decanting, formulation, and ultra-high-temperature (UHT) treatment, the resulting beverag

Alliances are volatile key components of many corporations' competitive strategies. They offer fast and flexible means of achieving market access, scale economies, and competence development. However, strategic alliances can encounter difficulties that often lead to disappointing performance. The authors suggest that the way partners manage the collective learning process plays a central role in t

Partially premixed combustion (PPC) is used to meet the increasing demands of emission legislation and to improve fuel efficiency. With gasoline fuels, PPC has the advantage of a longer premixed duration of the fuel/air mixture, which prevents soot formation. In addition, the overall combustion stability can be increased with a longer ignition delay, providing proper fuel injection strategies. In

Oxidized phospholipids occur naturally in conditions of oxidative stress and have been suggested to play an important role in a number of pathological conditions due to their effects on a lipid membrane acyl chain orientation, ordering, and permeability. Here we investigate the effect of the oxidized phospholipid 1-palmitoyl-2-azelaoyl-sn-glycero-3-phosphocholine (PazePC) on a model membrane of 1-

By counting the number of upcrossings of the mean level by a stationary Gaussian process one can estimate the mean frequency of the process. If the mean level is unknown and estimated from the observed mean level, then this crossing estimator is more or less biased, depending on the length of the observation interval. It is shown that if the interval is at least two mean wavelengths, then the bias

An adaptive predictor for discrete time stochastic processes with constant but unknown parameters is described. The predictor which in real time tunes its parameters using the method of least squares is called a self-tuning predictor. The predictor has attractive asymptotic properties. If the parameter estimation converges and if the predictor contains parameters enough, then it will converge to t
