Deuterated proteins and other bio-derived molecules are important for NMR spectroscopy, neutron reflectometry, small angle neutron scattering, and neutron protein crystallography. In the current study we optimized expression media and cell culture conditions to produce high levels of 3 different deuterated human carbonic anhydrases (hCAs). The labeled hCAs were then characterized and tested for de

An important challenge when coupling two different time dependent problems is to increase parallelization in time. We suggest a multirate Neumann-Neumann waveform relaxation algorithm to solve two heterogeneous coupled heat equations. In order to fix the mismatch produced by the multirate feature at the space-time interface a linear interpolation is constructed. The heat equations are discretized

MOx sensors are widely used for sensing gases. In this thesis a variable temperature MOx sensor was used to detect graffiti spray paint and differentiate it from other substances using the sensors sensitivity to different gases at different temperatures using machine learning. The machine learning methods Support Vector Machines, k-Nearest Neighbour and neural networks were evaluated and compared.

The degenerative process in Alzheimer´s disease (AD) follows a temporal and topographic pattern of early and accentuated involvement of temporal limbic, parietal and posterior cingulate cortices. We have studied a pedigree with four generations suffering from early onset AD linked to a presenilin-1 gene mutation. This family now contains 7 AD cases, neuropathologically confirmed in four cases of t

Gear hobbing is well established and one of the most cost effective manufacturing methods of involute gears. In the hobbing of lead crown corrected helical gears, a well know drawback is the non-uniform systematic tooth alignment deviation that arises. This is sometimes denoted as flank twist. The inevitable tooth alignment deviation, together with other source deviations, must not exceed the spec

Nu påbörjas årets lönerevision vid Luleå tekniska universitet som avser perioden 2024–10–01 –– 2025–09–30. Även i år har vi ett sifferlöst avtal. För medlemmar i Saco tillämpas på LTU lönesättande samtal vilket innebär att du som anställd i samband med lönerevisionen ska ha två samtal med din närmaste chef. Det första samtalet är tänkt att vara ett ömsesidigt utbyte av information avseende din pre

An integrated process for purifying a 6.1 kilo base pair (kbp) plasmid from a clarified Escherichia coli cell lysate based on an ultra/diafiltration step combined with polymer/polymer aqueous two-phase system and a new type of chromatography is described. The process starts with a volume reduction (ultrafiltration) and buffer exchange (diafiltration) of the clarified lysate using a hollow fibre me

Pålning är en typ av grundläggning lämplig för att grundlägga broar vid svaga markförhållanden. Att manuellt utforma en pålgrupp är en iterativ, tidskrävande process där snittkrafterna i pålarna måste verifieras för ett stort antal lastfall. Efter installationen kan pålarna dessutom ha nya positioner och kapaciteten måste verifieras igen. I detta projekt utvecklades en mjukvara för att automatiserFor bridges in weak ground conditions, piling is an appropriate type of foundation. To manually arrange the piles in a pile group is an iterative, time consuming process where the section forces in the piles must be verified for a large number of load cases. In addition, after installation, piles may have new positions and the capacity must be re-verified. In this thesis, a software was developed

The aim of this work was to develop a model of an integrated biomass-to-liquid process, consisting of hydrothermal liquefaction, evaporation, gasification and Fischer-Tropsch synthesis, using lignocellulosic forest residues as feedstock to produce hydrocarbons suitable for upgrade into drop-in biofuels. The energy, mass and carbon efficiencies that were achieved were 35%, 20% and 32%, respectively

Characterising the stop/start walking process of individuals in a crowded and congested space is an important consideration in modelling pedestrian movement. However, the reaction of pedestrians to speed changes, especially to the person in front, has not been fully characterised nor quantified for full adoption in computer models. This study, therefore, explored the different phases of the stop/s

We introduce rigorous theory for deriving first and second order backpropagation methods for Deep Neural Networks (DNN) whilst satisfying existing theory in DNN optimization. We begin by formally defining a neural network with its respective components and state the first and second order chain rule with respect to its partial derivatives. The partial derivatives in the chain rule formula are rela
