Elförsörjningen som till huvuddel kommer från fossila bränslen uppfyller vanligen inte efterfrågan i Irak. Samtidigt som det finns goda förutsättningar och stor potential för att installera och utnyttja solel som en lösning för den bristande elförsörjningen men med omtanke som värnar om miljön. Idag har cirka 20 procent av den irakiska befolkningen ingen tillgång till el, de återstående 80 procentThe main supply of electricity from fossil fuels does not usually meet demand in Iraq. At the same time, there are good conditions and great potential for installing and utilizing environmental friendly electricity from solar energy as a solution to the lack of power supply. Today, about 20 percent of the Iraqi population has no access to electricity, the remaining 80 percent have no continuous el

Polymers containing the Azo-benzene group have attracted attention due to anticipated uses such as materials for data storage, membranes with controllable permeability and materials with changeable solubility [1,2]. These expectations are due to the change in shape and dipole moment of the Azo-compound when excited by photo isomerization from the trans-state to the cis-state by UV light of ca 360

A few large fires in Lithium-ion battery systems are known to have been caused by leaking coolant, and experience from fire testing indicate that coolant can be the origin of violent fires triggered before the onset of thermal runaway in the battery. It is here hypothesized that the common coolants water and ethylene glycol can form flammable gases via electrolysis in the electrical environment fo

Recent years have seen a surge to develop first-row transition metal complexes with photophysics and photochemistry similar to those of noble metals, such as ruthenium and iridium. The reason for this is obvious, looking at their relative abundance. Iron stands out as the most abundant transition metal on earth, and is positioned right above ruthenium in the periodic table.The aim of this thesis h

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

Parity forbidden radiative transitions from metastable levels are observed in spectra of low-density astrophysical plasmas. These lines are used as probes of the physical conditions, made possible due to the long lifetime of their upper level. In a joint effort, the FERRUM project aims to obtain new and accurate atomic data for the iron-group elements, and part of this project concerns forbidden l

Photosynthetic organisms harvest and convert light energy into chemical energy and utilize it in their metabolism. The light is captured through pigments called chlorophylls and carotenoids, present in the thylakoid membranes inside the chloroplast. In addition to acting as auxiliary light harvesters, the carotenoids also act as antioxidants by 1) preventing the formation of reactive oxygen specie

Glyoxalase I (GlxI) is an important enzyme that catalyzes the detoxification of methylglyoxal (MG) with the help of glutathione (H-SG). It is currently unclear whether MG and H-SG are substrates of GlxI or whether the enzyme processes hemithioacetal (HTA), which is nonenzymatically formed from MG and H-SG. Most previous studies have concentrated on the latter mechanism. Here, we study the two-subs

This paper reports on studies of cellular instability of lean hydrogen/air laminar premixed flames with an equivalence ratio of 0.6 at a 5 atm and a 25 atm pressure. Numerical simulations employing a detailed chemical kinetics mechanism and detailed transport properties are carried out to simulate the initial linear growth of instability as well as the nonlinear evolution of flames. At the initial

The objective of this paper is to outline and discuss the key elements of an EU industrial development policy consistent with the Paris Agreement. We also assess the current EU Industrial Strategy proposal against these elements. The “well below 2 °C” target sets a clear limit for future global greenhouse gas emissions and thus strict boundaries for the development of future material demand, indus

An Eulerian Monte-Carlo approach, the so-called Eulerian stochastic fields (ESF) method is implemented and evaluated for simulation of non-premixed hydrogen/air combustion in supersonic flows. The ESF method is integrated into a compressible flow large eddy simulation (LES) solver, and validated on a supersonic combustor with a strut as flame-holder. Comparison with experimental data and with resu

Molten-salt-based nanofluids and ionic-liquid-based nanofluids are developed for thermal storage and heat transfer at relatively high temperatures, in the past few years. Preparation and stabilization techniques are briefly introduced firstly, and then, thermal properties, e.g., specific heat, thermal conductivity and viscosity, are summarized and discussed in detail. The properties are not only a

The urgent need to mitigate climate change has prompted researchers to investigate novel strategies to reduce greenhouse gas emissions. One promising technology that might ease the way for sustainable and circular economies is carbon capture and utilization (CCU), which not only captures CO2 emissions but also uses them to produce valuable products. This thesis investigates the potential of CCU in

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.

This thesis deals with intermediate energy heavy ion reactions with the particular aim to study the nuclear matter equation of state which defines the relation between statistical parameters of a fermionic system. The development of equipment for two experiments, CA47 at The Svedberg Laboratory in Uppsala, Sweden and R16 at Kernfysisch Versneller Instituut (KVI), Groningen, The Netherlands, are d

The increased demand for clean power in recent years has led to the development of various processes that include different types of CO2 capture. Several options are possible: pre-combustion concepts (fuel de-carbonization and subsequent combustion of H2), post-combustion concepts (tail-end CO2 capture solutions, such as amine scrubbing), and integrated concepts in which combustion is carried out

The aim of the project is to get a holistic picture of what happens to a person from the moment she dies till she is buried – transport, storage, ceremony etc. What can be done to adapt this procedure to the demands of the environment? Changing the material of a coffin is only one way of making the funeral closer to a total adaptation to the environment. I cannot change the contaminating burial me

Highly insulated external wall assemblies are commonly employed to enhance building energy performance. However, research indicates that these assemblies may lead to moisture-related issues, such as mould growth. Recent studies suggest that the use of highly hygroscopic insulation materials, owing to their higher moisture buffering value, may mitigate relative humidity levels and consequently the
