Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) har använts för att undersöka ålder och kemisk komposition av två texturellt skilda typer av monazit i leucosom och mesosom i polymetamorf aluminös migmatitgnejs vid Stensjöstrand, Halland. Dateringsresultat jämförs med tidigare publicerade zirkondateringar. Monazitkorn dokumenterades och undersöktes i tre tunnslip med hjälp aLaser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) has been utilised to investigate the age and chemical composition of two texturally different types of monazite in leucosome and mesosome of polymetamorphic aluminous migmatitic gneisses at Stensjöstrand, Halland. Results of radiometric dating are compared with previously published zircon dates. Monazite grains were documented

The intricate relationship between climate change and the building sector is characterized by a self-reinforcing loop. Rising temperatures driven by global warming will inevitably impact heating and cooling energy, while buildings simultaneously contribute significantly to carbon emissions throughout their lifecycle, further exacerbating climate change. However, current knowledge regarding the int

Exposure to diesel exhaust is associated with increased risk of cardiovascular and lung disease. Substituting petroleum diesel with renewable diesel can alter emission properties but the potential health effects remain unclear. This study aimed to explore toxicity and underlying mechanisms of diesel exhaust from renewable fuels. Using proximity extension assay (Olink), 92 proteins linked to inflam

Vibrational structures of the C1s and N1s photoelectron spectra of gas-phase HCN have been investigated using monochromated third-generation synchrotron radiation. Both spectra exhibit resolved fine structure associated with several vibrationally excited states. In the C1s spectrum a single vibrational progression is observed, while the N1s spectrum is more complex. High-level ab initio calculatio

We present a study of tunable high-order sum and difference frequency mixing in the 7-70 eV range, in xenon, argon and neon. We mix the light from a terawatt, subpicosecond titanium-sapphire laser and that from a tunable optical parametric generator. The radiation generated through mixing processes involves absorption or emission of one or Mo photons from the weak tunable source. The relative stre

The Swedish pulp and paper industry (PPI) accounts for almost 50 percent of industrial final energy use. It is an energy-intensive industry and process optimization is seen as prerequisite to compete on the global market. This alone should motivate company boards and on-site organisations to put energy management high on the agenda. Definitely, from time to time, energy issues (e.g. fuel shifts, s

The total area of Uttarakhand is about 53,483 km2, where 86% area is mountainous and 65% is covered by forest. The two main rivers Ganga and Yamuna originate from Uttarakhand. In addition to these two rivers, Uttarakhand has a large river and canal network that provides hydropower with immense reach. In 1907, one of India’s first hydropower stations was commissioned at Galogi (Uttarakhand). At p

Oil is very important for today’s society and the transportation sector is almost completely dependent on this material. Unfortunately, it affects the level of greenhouse gases negatively which in turn contribute to global warming. Therefore, it is necessary to reduce greenhouse gas emissions, especially in the sectors that emit the most, as transportation sector. The European Parliament has decid

This study addresses the challenge of precise, high-repetition-rate, single-shot measurements of the carrier–envelope phase in ultrafast optics. We constructed a Mach–Zehnder interferometer based on dual-arm white-light interference, and systematically investigated the intensity-to-phase coupling that arises during white-light generation. In the experiment, an acousto-optic modulator introduced sm

Teman vid Pufendorfinstitutet kan bjuda in internationella gästforskare - fellows - till Lund. Fler än 50 internationella forskare har hittills deltagit i International Fellows Programme och hjälpt oss att göra Pufendorfinstitutet till vad det är idag. Som uppskattade kollegor och ambassadörer fortsätter de att vara värdefulla samarbetspartners för institutet och för hela universitetet. Du kan läs

This article uses empirical investigation of regional hydrogen investments and strategies in Northern Europe to develop a new conceptual approach to regional industrial path development which foregrounds politics and power as explanatory factors in understanding the logics, processes and outcomes of path development. This conceptualisation departs from Evolutionary Economic Geography approaches to

Hydropower is a renewable energy that expected to be affected by persistent climate change in Mozambique. Variability of climate e.g. temperature and precipitation will contributors to future shortage of energy from renewable energy production especially for hydropower and biomass. This research reviews the impacts of climate change on the productions of hydropower in Mozambique. Furthermore, a st

The European pulp and paper industry (PPI) directly emits 31.9 Mton CO2 (2016) and indirectly 12.3 and 5 Mton CO2 from purchased electricity and transport respectively. It also accounts for 68 Mton of biogenic CO2 emissions. The PPI is a mature industry with overall stagnating market demand in the past ten years and relatively high levels of recycling. Forest countries like Sweden and Finland domi

The laser wake-field accelerator (LWFA) traditionally produces high brightness, quasi-monoenergetic electron beams with Gaussian-like spatial and angular distributions. In the present work we investigate the generation of ultra-relativistic beams with ring-like structures in the blowout regime of the LWFA using a dual stage accelerator. A density down-ramp triggers injection after the first stage

A comprehensive coarse grain model (CGM) is applied to simulation of biomass steam gasification in bubbling fluidized bed reactor. The CGM was evaluated by comparing the hydrodynamic behavior and heat transfer prediction with the results predicted using the discrete element method (DEM) and experimental data in a lab-scale fluidized bed fur
