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
Mobila teknologier har medfört en ökad flexibilitet i anställdas vardag. Detta har kommit att påverka de anställdas balans mellan arbete och fritid då de tilldelas arbetsuppgifter även på sin fritid. I denna studie undersökte vi hur dessa anställda upplever att smarttelefonen påverkar denna balans. Syftet var att belysa vilken inverkan den flexibilitet som smarttelefonen frambringar har på balanse
The ability of organisms to change color in response to a change in environmental conditions is widespread across taxa. Predation represents the longstanding hypothesis for the evolution of such coloration plasticity. Yet, tests of the evolutionary drivers of coloration plasticity remain rare. Here, we examine how predation shapes both baseline coloration and coloration plasticity in the Trinidadi
It is important to measure the relative humidity, RH, level in a concrete slab before applying semi permeable flooring to the surface. If the moisture level in the concrete is too high when the flooring is applied the high alkali level in combination with the moisture will degrade the adhesive. This paper describes a new system used to continuously measure and monitor RH in situ during the constru
The objective of this Master’s Thesis, entitled “How to increase tolerance regarding co-planarity when using larger shield cans”, is to find solutions for how to solder larger shield cans to the printed wired board (PWB) without losing shielding effectiveness. Advantages with larger shield cans, i.e. combining several smaller shield cans into one large with internal walls, are saved board space, e
Agenda 2030 Graduate School monthly newsletter #7 2025-08-11 Ylva van Meeningen Hi! It is once again August and the Agenda 2030 Graduate School’s office is back in business. Time to brush of all you have put to the side for a later day and to try and figure out what it was you were working on before you went away. My big summer vacation project for one was a success! Going interrailing through Eur
Declining biological production as a part of an ongoing land degradation process is considered a severe environmental problem in the dry northern and northwestern regions of China. The aim of this study is to develop and adapt a satellite data-driven gross primary production model called Lund University light use efficiency model (LULUE) to temperate conditions in order to map gross primary produc
This contribution comprises a comparison of capacity performances of MIMO terminal antenna configurations for smart phones at 2.65 GHz, measured in an extensive 2×2 MIMO measurement campaign in noise- and interference-limited urban environments. Whereas, on average along the route, the performances where dictated by the received power, locally the eigenvalue dispersion of the communication channel
Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster. Theoretical studies have indicated that some of these clusters can

Populärvetenskaplig sammanfattning: Mössbauerspektra är en metod som används för att bestämma hur ett mineral, eller molekyl, är uppbyggt. Man undersöker ett visst grundämne, inom geologin undersöker man oftast järn. Efter att ha analyserat ett prov i spektrometern kan man få uppgifter om var och hur järnet sitter i mineralet, eller molekylen. Metoden bygger på att man skickar gammastrålning av eThe Mössbauer effect is used in this work to determine the oxidation and site occupation in biotites that have been treated in different pHs. The work also gives an introduction to the theory behind the Mössbauer effect as well as Mössbauer spectroscopy. It is obvious that the pH has a significant role in the oxidation of the biotites, the more acidic the sample the more it will be oxidised. It is
Abstract in UndeterminedA family of iterative receivers is evaluated in terms of complexity and performance for the case of an uplink multi-user (MU) multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) system. The transmission over block fading channels is considered. The analyzed class of receivers is performing channel estimation inside the iterative detection l
