Nitrogenase is the only enzyme that can convert N2 into NH3. The reaction requires the addition of eight electrons and protons to the enzyme and the mechanism is normally described by nine states, E0–E8, differing in the number of added electrons. Experimentally, it is known that three or four electrons need to be added before the enzyme can bind N2. We have used combined quantum mechanical and mo

A method for simultaneous extraction and quantification Of four non-steroidal anti-inflammatory drugs (NSAIDs) based on continuous flow hollow fiber liquid-phase microextraction (CFHF-LPME) was developed. The effect of sample flow rate, acceptor flow rate, type of acceptor flow (continuous, semi-continuous or forward-backward), type of supported liquid membrane and sample volume was studied. The e

The construction sector has been criticised in recent years for being inefficient. The critique involved describes finished buildings as having flaws and there being a lack of interest within the construction sector in assembling knowledge and sharing experience. The construction industry has started working with questions of how efficiency can be increased by reducing the errors made. Knowledge

Popular Abstract in Swedish Genetisk information lagras i DNA, som är en mycket stabil molekyl. I våra celler finns samma gener i alla celler. Det är därför av yttersta vikt att uttrycket av generna kan regleras olika i olika vävnader. Bakterier, som är encelliga organismer, måste för att kunna överleva noga kontrollera uttrycket av olika gener beroende på växlingar i omgivningen. Jag har studeratGenetic information, which is stored in DNA, is transferred to messenger RNA (mRNA) in a process called transcription. mRNAs are then translated by ribosomes into proteins which, with some important exceptions, catalyze chemical reactions in cells. Since cells must be able to adapt to changes in the environment, mRNAs must be unstable. The present investigation concerns mRNA degradation mainly in

Resolving the spatial and temporal dynamics of gross primary productivity (GPP) of terrestrial ecosystems across different scales remains a challenge. Remote sensing is regarded as the solution to upscale point observations conducted at the ecosystem level, using the eddy covariance (EC) technique, to the landscape and global levels. In addition to traditional vegetation indices, the photochemical

Urban trees are uniquely valuable in towns and cities for the ecosystem services they provide their citizens and can as such be considered a potent source of public goods and positive externalities - even when these trees are found on private properties. The importance of urban trees will only grow as events of severe heat and extreme rainfall become more and more frequent and the urgency to reduc

The digital platform Airbnb has gained popularity in a number of countries particu- larly in the Maltese islands. Striking a balance in setting a price that is competitive and also renders a good profit can be a challenge. In this thesis a model is de- veloped to predict the price of a listing in the Maltese islands for September 2022 through a machine learning approach whereby five types of model

Timing of return to the breeding area presumably optimizes breeding output in migrants. How timing affects the other components of fitness — survival, has been comparatively little studied. Returning too early in spring is expected to be associated with high mortality in insectivorous migrants when weather conditions are still unsuitable. Yet, males in particular arrive early to get access to the

In the present study, one type of uniformly nanostructured surface (NPDS) was modified by electrophoretic deposition. Two kinds of micro/nanostructured surfaces (FLS1 and FLS2) were fabricated on copper surfaces by femtosecond laser processing. The micro/nanostructured surfaces were further modified by electrophoretic deposition. Afterwards, composite micro/nanostructured surfaces (CS1 and CS2) we

Vector navigation, i.e., maintaining a constant heading for a given amount of time, is hypothesized to provide a viable basis for the navigational feats of a number of long-distance animal migrants. Since animals following this strategy are subject to drift by wind or by ocean current, performing long migrations relying on vector navigation is particularly challenging. We tested whether vector nav

Wild waterfowl are important reservoir hosts for influenza A virus (IAV) and a potential source of spillover infections in other hosts, including poultry and swine. The emergence of highly pathogenic avian influenza (HPAI) viruses, such as H5N1 and H5N8, and subsequent spread along migratory flyways prompted the initiation of several programs in Europe, North America, and Africa to monitor circula

Background: To determine the feasibility and efficacy of a retinal telephotocoagulation treatment plan for diabetic macular edema. Methods: Prospective, interventional cohort study at two clinical sites. Sixteen eyes of ten subjects with diabetic macular edema underwent navigated focal laser photocoagulation using a novel teleretinal treatment plan. Clinic 1 (King Khaled Eye Specialist Hospital, R

Membrane-bound water channels known as aquaporins (AQPs) facilitate water transport across biological membranes along osmotic gradients. Since all living cells depend on their ability to maintain water homeostasis, this must be tightly regulated. In eukaryotes, this is achieved by gating, which involves a conformational change of the protein, thereby physically blocking water transport, or by traf

New antimicrobial agents are needed to address the ever-growing risk of bacterial resistance, particularly for methicillin- and vancomycin-resistant Staphylococcus aureus (S. aureus). Here, we report a class of bile acid oligomers as facial amphiphilic antimicrobials, which are noncovalently fabricated by cholic acid (CA) and deoxycholic acid (DCA) with polyamines (e.g., diamines, diethylenetriami
