The tea sector is one of Kenya's most important industries, with a big impact on the country's economy and socio-economic development. At the same time, tea manufacturing is highly energy-intensive and strongly affected by electricity tariffs and high production costs. Due to the favorable weather conditions and growing renewable energy ambitions in Kenya, Solar Photovoltaic (PV) systems p
Sveriges elsystem genomgår en förändring i takt med att andelen väderberoende kraftproduktion ökar. Kraftvärmeverk, som traditionellt haft en tydlig roll som planerbar kraft, möter ett allt hårdare ekonomiskt tryck när marginalerna på spotmarknaden pressas. Detta examensarbete undersöker hur ett kraftvärmeverk i elområde SE3 kan förbättra sin lönsamhet genom deltagande på mFRR D-1 kapacitetsmarknaSweden’s electricity system is undergoing change as the share of weather-dependent power production increases. Combined heat and power (CHP) plants, traditionally valued for their dispatchability, face growing economic pressure as spot market margins tighten. This thesis investigates how a CHP plant in Swedish electricity area SE3 can improve its profitability by participating in the manual freque
α-CGRP 8-37 is a peptide fragment of calcitonin gene-related peptide and is commonly used as a CGRP antagonist in pharmacological research. CGRP signaling has been discussed in relation to neuroimmune mechanisms in psoriasis, but a practical development of α-CGRP 8-37 requires analytical methods and formulation strategies that can handle peptide instability, adsorption, and matrix effects. The aim
This thesis investigates the design and evaluation of Large Language Model (LLM) agent assistants for industrial maintenance, developed in cooperation with SSAB. The study focuses on identifying what combinations of tools and architectures best serve the needs of maintenance technicians, with an emphasis on practical usability and factual correctness. Multiple agents were developed and compared,
Methods: The study population of healthy adult volunteers was divided into a sample for development of a prediction model (n = 63) and a testing sample (n = 30). Magnetic resonance imaging data were used to assess anatomical characteristics of the left ventricle: the angle between papillary muscles (PMA), the length of the left ventricle (LVL) and left ventricular mass (LVM). Twelve-lead electroca
The European Association of Urology renal cancer guidelines have been updated to recommend nivolumab and cabozantinib over the previous standard of care in patients who have failed one or more lines of VEGF targeted therapy.
Objective. The purpose of this work was to develop an inexpensive phantom for simplified image quality assurance (IQA) together with algorithms for objective evaluation of image quality parameters and to integrate these components into an easy-to-use software package. This should help make quality control of dental cone beam computed tomography (CBCT) units accessible, easy, and affordable for any
In this study we report on the production of metal-hydroxide-coated macroporous polymers (MHCMPs), which mainly involves a polyacrylamide backbone coated with iron-aluminium double hydroxides. The coating process is fast, occurs using relatively mild reagents at room temperature, and can be repeated multiple times, thus making it a very simple and flexible process. Electron microscopy and energy d
We study in detail various aspects of the renormalization of the spin-1 resonance propagator in the effective field theory framework. First, we briefly review the formalisms for the description of spin-1 resonances in the path integral formulation with the stress on the issue of propagating degrees of freedom. Then we calculate the one-loop 1(--) meson self-energy within the resonance chiral theor
In this article, we attempt to develop a meta-language for a relational approach to urban walking that is able to account for walking as a mutable, embodied, materially heterogeneous and distributed activity. Following the perspective on walking as developed in a series of articles by Jennie Middleton, we develop a notion of the walker as a socio-technical assemblage. By recognising walking as an
Synapsins are a family of phosphoproteins that modulate the release of neurotransmitters from synaptic vesicles. The release of insulin from pancreatic beta-cells has also been suggested to be regulated by synapsins. In this study, we have utilized a knock out mouse model with general disruptions of the synapsin I and II genes [synapsin double knockout (DKO)]. Stimulation with 20 mM glucose increa
Sexual selection against immigrants is a mechanism that can regulate premating isolation between populations but, so far, few field studies have examined whether males can discriminate between immigrant and resident females. Males of the damselfly Calopteryx splendens show mate preferences and are able to force pre-copulatory tandems. We related male mate responses to the ecological characteristic
Many gasification plants use scrubber systems for the removal of tars from producer gas. The cost of the scrubber liquid represents a considerable part of the operating cost, which could be decreased by regenerating the spent scrubber liquid by separating it from ash residues and heavy tars. In this study, different types of spent scrubber liquids were regenerated using a centrifuge. The effect of
Desferrioxamine-B (DFOB) is a bacterial trihydroxamate siderophore and probably the most studied to date. However, the manner in which DFOB adsorbs at mineral surfaces and promotes dissolution is still under discussion. Here we investigated the adsorption and dissolution reactions in the goethite-DFOB system using both in situ infrared spectroscopic and quantitative analytical methods. Experiments
Pheromones are central to the mating systems of a wide range of organisms, and reproductive isolation between closely related species is often achieved by subtle differences in pheromone composition. In insects and moths in particular, the use of structurally similar components in different blend ratios is usually sufficient to impede gene flow between taxa. To date, the genetic changes associated
Children born after assisted reproductive technologies (ART) have an increased morbidity. The risk of developing cerebral palsy is nearly doubled and the risk of developing epilepsy is also higher. Behavioural problems including attention deficit/hyperactivity disorder may be more common in children born following ART than among naturally conceived children but the finding is uncertain. Data on au
Betatron x-ray emission in laser plasma accelerators is a promising compact source that may be an alternative to conventional x-ray sources, based on large scale machines. In addition to its potential as a source, precise measurements of betatron emission can reveal crucial information about relativistic laser-plasma interaction. We show that the emission length and the position of the x-ray emiss
The use of bibliometric indicators on individual and national levels has gathered considerable interest in recent years, but the application of bibliometric models for allocating resources at the institutional level has so far gathered less attention. This article studies the implementation of bibliometric measures for allocating resources at Swedish universities. Several models and indicators bas
