Nitrogenase is the only enzyme that can cleave the triple bond in N2, making nitrogen available for all lifeforms. Previous computational studies have given widely diverging results regarding the reaction mechanism of the enzyme. For example, some recent studies have suggested that one of the μ2-bridging sulfide ligands (S2B) may dissociate from one of the Fe ions when protonated in the doubly
PURPOSE: To develop a psychometrically robust electronic patient reported outcome measure (ePROM) for refractive surgery. SETTING: Moorfields Eye Hospital, London, United Kingdom. DESIGN: Questionnaire development study. METHODS: Items were derived in 6 domains (spectacle dependence, visual quality, eye comfort, functional freedom, emotional wellbeing, and satisfaction with treatment) from existin
Nanometric cutting of a single crystal copper workpiece of different crystallographic orientations by a stiff cylindrical cubic diamond tool has been investigated by MD simulations using the freeware LAMMPS. The chip evolves during the cutting process and forms depending on crystal orientation, cutting velocity and tool geometry. It was found that no significant difference in the cutting force mag
The 1H and 13C NMR parameters, i.e., chemical shifts and coupling constants, for the pentasaccharide of the Forssman antigen and overlapping di-, tri-, and tetra-saccharide sequences thereof have been measured and assigned completely using 1D and 2D techniques, and the oligosaccharide structures have thereby been confirmed. Nuclear Overhauser effect (NOE) experiments have been carried out at three
Investigating the optical properties of various chemical compounds using UV-vis spectrophotometers is an essential part of education in chemistry. However, commercial spectrophotometers are usually treated as "magic black boxes", where the dominant majority of optical elements are hidden "under the hood". This often limits understanding of the mechanisms behind the generation of spectral curves, w
OBJECTIVE: To investigate the trajectories of work and activity impairments among people participating in a digital self-management program for osteoarthritis (OA).METHODS: We conducted an observational longitudinal study using data for baseline, 3, 6, 9 and 12 months follow ups from people participating in a digital OA treatment between June 2018 and September 2021. The Work Productivity and Acti
Smart cities are increasingly advocated by governments and the private sector as the primary means to deliver urban sustainability. Particularly in Europe and North America, the smart city is envisioned as a place where digital technologies are deployed to ‘solve’ urban sustainability problems. Such visions have been broadly cri- tiqued in the urban studies literature for reflecting techno-utopian
Atmospheric inversion approaches are expected to play a critical role in future observation-based monitoring systems for surface fluxes of greenhouse gases (GHGs), pollutants and other trace gases. In the past decade, the research community has developed various inversion software, mainly using variational or ensemble Bayesian optimization methods, with various assumptions on uncertainty structure
Utveckling av jordbrukssektorn är en av de viktigaste prioriteringarna för den Etiopiska staten när det kommer till att upprätthålla landets ekonomiska utveckling. Ett sätt att uppnå detta är att satsa på storskaliga utvecklingsprojekt inom jordbruket, till exempel Tana Beles Sugar Development Project som den här uppsatsen kretsar kring. För att kunna anlägga detta har stora landarealer tagits i aDevelopment of the agricultural sector is among the top priorities for the Ethiopian government in order to keep up the economic development in the country. One way of reaching this is to undertake large-scale development projects, such as the Tana Beles Sugar Development Project described in this thesis. For this, large areas of land are required for the plantations. This land is expropriated fro
Albania is a country situated in the western Balkan peninsula, it is a parliamentary democracy and a transitional economy. Its population is approximately 3.5 million with 870.00 populating its capital Tirana.1 The Mediterranean country underwent its most difficult times during the communist regime, where the dictator Enver Hoxha ruled the country with an iron fist for 40 years. His policies exerc
Tidtabeller är nyckeln för att utnyttja den tillgängliga kapaciteten på järnvägen på ett optimalt sätt. I Sverige är det Trafikverket som tilldelar kapacitet genom att årligen ta fram en tågplan som specificerar alla tåg som ska framföras det kommande året. Att ta fram tågplanen är en komplex uppgift som försvåras av infrastrukturens begränsningar och att alla aktörer är beroende av varandra. När Timetables are the key to utilizing the capacity on the railway in an optimal way. In Sweden, the Swedish Transport Administration, Trafikverket, makes the allocation of capacity. It is done by preparing an annual timetable specifying all trains that will run the following year. Creating the annual timetable is a complex task made difficult by limitations in the infrastructure and because all acto
Based on the debate in the media following the SOU (2003:49)-reports different suggestions to strengthen the childs role in the adoption process, we started considering the adoptive parents reactions to all this. Has anyone asked them? What support would they want? The objective of our paper was to present the result of a number of interviews with adoptive parents regarding some of the questions f
