Induction hardening is a useful method for improving resistance to surface indentation, fatigue and wear that is favoured in comparison with through hardening, which may lack necessary toughness. The process itself involves fast heating by induction with subsequent quenching, creating a martensitic layer at the surface of the workpiece. In the present work, we demonstrate how to simulate the proce
A core-excited I = (12+) spin-gap isomer was identified in 98Cd in an experiment at EUROBALL IV. It was found to feed the known I = (8+) seniority isomer by an E4 transition. Half-lives of T1/2 = 0.23() µs and 0.17() µs were measured for the two states at Ex = 6635 keV and 2428 keV, respectively. From the excitation energy of the core-excited isomer a 100Sn shell gap of 6.46(15) MeV is inferred. T
Little is known about how microbes diversify in nature. In contrast to the more studied multicellular organisms, microbes can have a) huge population sizes, b) high reproductive rates and c) long-distance dispersal. These characteristics can affect their tempo and mode of diversification in ways that still need to be understood. For instance, it has been proposed that the huge population sizes and
Calculates the full width at half maximum (FWHM) of the phonon broadening function for Li, Na, K and Al at different temperatures. A theory is used which employs the ionic pseudopotential, rather than, as in Bergersen et al's (1971) theory, a bare Coulomb potential. Despite the fact that a pseudopotential in a general sense is weaker than a Coulomb potential the authors find that the former gives
New approaches in agriculture utilizing plant-growth promoting microorganisms have the potential to decrease our reliance on artificial fertilizers and pesticides, which is an evergrowing societal concern. Fungi of the genus Trichoderma are abundant in soils all over the world and can positively affect plant stress tolerance and yield. However, this growthpromoting effect is dependent on the plant
This work constitutes the results from a one year master thesis research project (Sep, 2019 to Aug, 2020). Metal-Organic Frameworks (MOFs) have been used for encapsulation of homogeneous catalysts to generate heterogeneous catalysts. This work describes the incorporation of the non-heme iron complex [(Fe(II)N4Py)]2+ and two molybdenum−sulfur clusters (MOS) into the pores of UiO-type MOFs via absor
Vätgas är en energikälla som har en energidensitet (per massa) tre gånger så stor som naturgas. Detta gör så att vätgas är en huvudkandidat för morgondagens bränsle. Ett av de viktigaste forskningsområderna för vätgas innefattar produktion av vätgas eftersom det finns en stor mängd metoder för vätgasproduktion. Återvinnbar vätgas kan potentiellt produceras med vattenelektrolys, som undersöks i detHydrogen gas is an energy source that has an energy density (per mass) that is three times as large than the energy density of natural gas. This qualifies hydrogen gas as a prime candidate for the fuel of tomorrow. One of the main research areas for hydrogen include the production of it as there are a vast amount of methods of hydrogen production. Renewable hydrogen can potentially be produced thr
This thesis presents studies of three different Quark-Gluon Plasma estimators in proton-proton collisions using what is currently believed to be quark-gluon plasma observables; radial flow, elliptic flow and strangeness enhancement. The three tested estimators were Transverse Spherocity, an altered version of Transverse Spherocity where all p_T was put to one, and a newly developed estimator calle
Informal settlements, or unplanned sectors of the city, are vital for providing shelter for low and middle income households in the developing world. In the case of Dar Es Salaam, Tanzania, informal settlements have a long history dating back to the early colonial beginnings and today provide housing to over 70% of the city. In these densely populated environments of the informal sector, resident
Visualizing results is an important part of Finite Element (FE) modeling. Many tools exist for visualizing these results, they are often part of complete software packages for FE analysis. These packages often rely on the user being familiar with FE analysis, making them unsuitable for use in teaching the FE Method. CALFEM (Computer Aided Learning of the Finite Element Method) is an FE toolbox de
“You smell that? Smell that. This is legacy.” - Aldo Gucci [Al Pacino, The House of Gucci] Recently, the movie ‘House of Gucci’ was released revolving around the dark twists and turns that the brand Gucci went through internally. Including the rise and fall of the Gucci dynasty, from betrayal to murder. While based on actual events, the movie is heavily dramatized. While it is certainly entertaini
Systems evaluating potential treatment methods for Parkinson’s disease and chronic pain conditions, using rodent experimental models, are highly needed. Currently used systems are aiming to evaluate these kinds of treatment methods by analyzing the animal’s motor behavior. These systems either generate binary data or multifaceted data for when the rodent is spatially limited or data for when the r
Sedan den 24 februari 2022 har Europeiska unionen stått inför ett konventionellt krig på sin tröskel och en ökad geopolitisk spänning från öst. Detta har krävt av Rådet att agera snabbt och kraftfullt inom ramen för sin kompetens för den gemensamma utrikes- och säkerhetspolitiken. För att motverka Rysslands aggression har rådet utfärdat omfattande sanktionspaket som aldrig tidigare har använts i sSince 24 February 2022, the European Union has faced a conventional war on its doorstep and an increase in geopolitical tension with the East. This has required the Council to act quickly and forcefully within its competence in the area of Common Foreign and Security Policy. To counteract the adverse geopolitical actions the Council has issued sanctions packages which have never been utilized befo
