Continuing our work toward a system mimicking the electron-transfer steps from manganese to P680+ in photosystem II (PS II), we report a series of ruthenium(II)-manganese(II) complexes that display intramolecular electron transfer from manganese(II) to photooxidized ruthenium(III). The electron-transfer rate constant (kET) values span a large range, 1 × 105-2 × 107 s-1, and we have investigated di

This work describes the development of a heavy-metal biosensor based on either recombinant 6His-Tag glutathione S-transferase (GST-(His)(6)) or glutathione S-transferase Theta 2-2 (GST-theta 2-2), and a capacitive transducer. The dynamic range of the pure bovine liver GST-Theta 2-2 biosensor was 1 fM to 1mM for Zn2+, and 10pM to 1mM for Cd2+. The GST-(His) 6 biosensor was able to detect Zn2+ and C

Thin films of different derivatives of fluorinated alkyl phosphoric acids have been deposited from aqueous solutions onto surfaces of oxidized polycrystalline nickel stamps. which are commonly used in several industrial applications of nanoimprint lithography (NIL). The films have been established in order to increase the antiadhesion tendencies at the stamp polymer interface. Thicknesses, chemica

Confidentiality is a major determinant of the accessibility and acceptability of sexual and reproductive health care for adolescents. Previous research has revealed that Lithuanian adolescents lack confidence in guarantees of confidentiality in primary health care settings. This study aimed to assess the factors that affect general practitioners' decisions whether to respect confidentiality for Li

We have studied the mechanism of A- 769662, a new activator of AMP- activated protein kinase ( AMPK). Unlike other pharmacological activators, it directly activates native rat AMPK by mimicking both effects of AMP, i. e. allosteric activation and inhibition of dephosphorylation. We found that it has no effect on the isolated alpha subunit kinase domain, with or without the associated autoinhibitor

G protein-coupled receptor 30 (GPR30) is a ubiquitously expressed receptor reported to bind and become activated by estrogen (17β-estradiol). However, the role of GPR30 as an estrogen receptor for rapid estrogenic signaling is not completely accepted, and controversies exist regarding the identity of the cognate ligand, signaling, and subcellular localization of the receptor. Expression of GPR30 i

In this thesis the heating area of a belt furnace for annealing metal powder has been modeled. The model was extended with PI-controllers for controlling the energy added to the model. It was simulated with differently tuned controllers to test tuning principles for finding suitable control parameters for the process. The most promising tuning principles was then written as a manual with the aim f

Since the introduction of Edison’s lightbulb over one-hundred years ago, humanity has struggled to keep up with electrification for all. With global attention now aimed at sustainable energy production, the struggle becomes more complex by not only obliging energy access, but access to clean energy. The concept of microgrids has been promising for filling in the demand, but not quickly enough to m

Neonicotinoid insecticides are agonists to nicotinic acetylcholine receptors (nAChRs) in the brains of insects. At sub-lethal doses these chemicals cause behavioral abnormalities in several bee species, reducing overall fitness. nAChRs expressed in the optic lobes of insects bind neonicotinoids, thus may be involved in these behavioral changes. Here we attempted without success to visualize the pr

G protein coupled receptors (GPCRs) is the largest superfamily of membrane proteins and convert a multitude of extracellular signals and turn them into intracellular responses by binding and activating just a few G proteins. The mechanism for activation is very conserved and is likely to be similar for all GPCRs and G proteins, but how a vast amount of GPCRs selectively couple to specific G protei

2016-2018, a national user-led organization within the psychiatric field in Sweden established a partnership-based model regarding the implementation and management of peer support within psychiatric health care units. This study was based on a user-led organization and a psychiatric health care organization about to initiate such a partnership. The aim was to examine how these parties constructed

In this study, the extraction and isolation of xylan from milled oat hull materials was investigated. Alkali extraction by 2 M sodium hydroxide at 40°C overnight was applied. The yield of extracted xylan was 5%. The extracted xylan was isolated from the extraction mixture by ethanol (99.9%) after neutralization and its purity was checked, resulting in a66% pure product. The semi-purified xylan was

Tolkning och kvantifiering av strålningseffekter pga. atmosfäriska partiklar är en signifikant del av IPCC’s modellering av hur tidigare klimat förändrats och hur förändringar i framtiden kommer se ut. I den här studien vill vi strukturera och analysera observationer av huvudsakligen svavelpartiklar positionerade i stratosfären från naturliga och möjligtvis mänskliga källor, med hänvisning till va

Applied Machine Learning in Steel Industry – Examination of possible applications of machine learning for SSAB Oxelösund In modern industry there are high demands for increased resource efficiency that in part are motivated by the stronger competition on the global market, as well as by the societal necessity for a more sustainable industry. This master thesis project examines applied machine lear

I detta arbete återgår författaren till grundtekniken och undersöker hur detta påverkar spelet. Ämnen som tas upp är vibrato, stråkteknik, koordination och styrka i vänsterhand samt hur dessa korrelerar med varandra.In this project the author goes back to basics and revisits old exercises to see how this impacts the playing. Subjects as vibrato, bow technique, coordination and strength in the left hand is discussed.

Distribution is a part of the supply chain and refers to the steps taken to move and store a product from the supplier stage to the customer stage in the supply chain. Direct shipment is a concept within distribution and refers to shipping direct between a supplier and a retailer or customer. Distribution is considered a key driver for overall profitability of a company since it directly affects b

The Russian state-funded news media RT, formerly Russia Today, has since its start in 2005 created a reputation for acting as Kremlin's propaganda machine and part of Russia's political hybrid warfare. Previous research indicates that RT actively conducts psychological influence operations with the aim of legitimise Russia’s politics among the readers. By adopting a theory-developing appro
