Nitrogenase is the only enzyme that can cleave the triple bond in N2, making nitrogen avaiable for other organisms. It contains a complicated MoFe7S9C(homocitrate) cluster in its active site. Many computational studies with density-functional theory (DFT) of the nitrogenase enzyme have been presented, but they do not show any consensus-they do not even agree where the first four protons should be
Purpose: Applying diffusion and perfusion metrics for evaluation of low-(LGG), high grade glioma (HGG) and metastases (MET) for differential diagnosis. Materials and Method: 43 patients (18HGG, 10 LGG, and 15MET) were included. MR data for tumour volume, perilesional edema, rCBF-, rCBV-, FLAIR-, FA-, ADC-maps were quantified by regions of interest (ROI). Measures of different parameters, and ratio
Friction is a subject of importance from many points of view. It controls the relative motion between two bodies in contact and most manufacturing methods based on engagement between a tool and a workpiece are dependent on the prevailing frictional conditions. The outcome in terms of part quality from manufacturing methods like sheet forming is directly connected to the frictional state. The aim
The importance of using efficient bases for current expansion in numerical computations of electromagnetic field problems has been emphasized for several decades. It is well known that the basis functions should approximate the physical current (electric or magnetic) to some extent. Moreover, for efficiency, it is reasonably to require that only a few basis functions are needed in order to obtain
Vid medicinska fakulteten i Lund forskar man inte bara inom medicin, det forskas även om lärande och undervisning. Vi har intresserat oss för denna utbildningsvetenskapliga forskning och velat ta reda på vad den handlar om, hur den relaterar till fakultetens utbildningsverksamhet, samt varför den har genomförts. Särskilt har vi undrat om forskningen är att betrakta som SoTL, dvs Scholarship of Tea
