En hybridpark bestående av vind- och solkraft förbättrar vätgasproduktionens prestanda jämfört med ifall kraftslagen agerar separat och kan dela på samma infrastruktur. Detta examensarbete är en förstudie som granskar möjligheten för två vindkraftverk med en effekt på vardera 2 MW att kompletteras med en solcellspark för att bilda en hybridpark med vätgasproduktion. Förstudien undersöker dess teknA hybrid power plant (HPP) existing of wind- and solar power improves the performance of the hydrogen production compared to the stand-alone alternative and can share infrastructure. This thesis views the possibility for two wind turbines with 2 MW power each to be combined with solar power to form a HPP with hydrogen production. The thesis investigates the plant’s technical, economic and permits

Beräkningsmodeller kan hjälpa oss förstå benvävnadens unika förmåga att avleda sprickor och skydda sig mot benbrott Sannolikheten att råka ut för ett benbrott ökar för äldre och bensköra personer. Hos en ung och frisk person så har benvävnaden i vårt skelett en unik förmåga att skydda sig mot benbrott genom att avleda mikrosprickor. Men med ålder och sjukdom blir skelett svagare och sprickor och Human cortical bone tissue is a complex and strong composite material, with the ability to resist damage via slowing, stopping or redirecting propagating cracks. However, the ability is impaired with age. At the microscale, changes are seen both in terms of increased porosity and as changes in local material parameters. The microstructure is based on circular concentric layers of bone tissue, call

Uppsatsen syftar till att utreda ersättningssystemet av rättegångskostnader i förvaltningsprocessen och hur väl det stämmer överens med rätten till en rätt-vis rättegång. Särskilt kommer avgörandet HFD 2022 ref. 10 att redogöras för och kritiseras. Arbetet tillämpar en kritisk rättsdogmatisk metod. I förvaltningsprocessen gäller som huvudregel kvittningsprincipen, som inne-bär att parterna bär siThe study’s ambition is to examine the order of reimbursement of legal costs in the administrative law procedure and how it compels to the right of a fair trial. In particular, the ruling by the Supreme administrative court (HFD 2022 ref. 10) will be exposed and criticized. The paper uses a critical legal dogmatic method. In the administrative procedure, the principle of set-off applies, which me

Background: Improving maternal and reproductive health still remains a major challenge in most low-income countries especially in sub-Saharan Africa. The growing inequality in access to maternal health interventions is an issue of great concern. In Ghana, inadequate attention has been given to the inequality gap that exists amongst women when accessing antenatal care during pregnancy and skilled a

This article investigates and discusses a football chant, a riff from a popular rock song entitled “Seven Nation Army” by the rock group The White Stripes from Detroit, USA. The chant is sung by supporters at football matches even in Sweden but also in corresponding social contexts, as when high school students graduate or at the pub. The survey, which was to by a reduction method compare the riff

Syftet med denna uppsats är att undersöka huruvida ”post-earnings-announcement drift” sker för företagen på OMXS30-indexet. För att testa detta konstrueras en eventstudie som avser att testa om den kumulativa oväntade medelavkastningen skiljer sig från noll i olika tidsperioder före och efter företagen har publicerat kvartalsrapporter. Urvalet delas upp i ”positiva nyheter”, som avser de kvartal d

This is a comparative study of several widespread and canonical texts from the lowlands of the Middle East and North Africa, with regard to historically reoccurring interconnected traits of ideal state structure among cultures, where Semitic languages have been main languages of communication from the 18th century BC to the modern day. The study is of reoccurring ideals of state structure with def

In today’s society there is an obsession with finding happiness. According to the coca-cola company, all you need to do is open happiness1, but why stop with a can of coke when you can find your happiness on a dating site. It even seems to come in edible form in your local shop. But what exactly is happiness? De Saussure spoke of “the arbitrary nature of the sign” as a two part model; “the signifi

Ocean acidification is a consequence of the anthropogenic release of carbon dioxide (CO2) to the atmosphere. When CO2 is dissolved in water it affects the composition of ions and lowers the pH of the water. As the partial CO2 pressure in the atmosphere increases a new balance is reached with the surface waters which causes the pH of the surface oceans to decrease. For small shallow seas this effec

We have measured the core-valence double ionization spectra of carbon suboxide above both the O 1s and C 1s edges. Following several core-valence cases known in the literature, to begin with the spectra are compared with the well-known single ionization valence photoelectron spectrum of this system, from which they surprisingly differ quite strongly. This motivates a comparison to electronic struc

In order to improve curve safety, warning signs are used to alert drivers to unexpected changes in horizontal alignment and speed variations. While all countries have standards and guidelines for signs, markings and delineations to ensure a uniform system, they do not use them in the same way and choices and combinations may differ. SAFESTAR project promoted a method for establishing uniform curve

Objectives: Improved prediction modeling in osteoarthritis (OA) may encourage risk reduction through calculation of individual and population lifetime risks. There are currently no prediction models for hand OA. Thus, we aimed to 1) develop a prediction model for hand OA in men and 2) to contrast its discriminative performance to a prediction model for lung cancer and chronic obstructive pulmonary

We report magnetic properties and relative paleointensity (RPI) proxies from a suite of 10 conventional piston cores and Kasten cores from the SW Iberian Margin collected during cruise JC089 of the RSS James Cook in August 2013. Mean sedimentation rates are in the 10–20 cm/kyr range. Age models were acquired by correlation of Ca/Ti and Zr/Sr XRF core-scanning data to L* reflectance from the Cariac

UNLABELLED: When microbes contaminate the macrophage cytoplasm, leukocytes undergo a proinflammatory death that is initiated by nucleotide-binding-domain-, leucine-rich-repeat-containing proteins (NLR proteins) that bind and activate caspase-1. We report that these inflammasome components also regulate autophagy, a vesicular pathway to eliminate cytosolic debris. In response to infection with flag

Context. Wide hot subdwarf B (sdB) binaries with main-sequence companions are outcomes of stable mass transfer from evolved red giants. The orbits of these binaries show a strong correlation between their orbital periods and mass ratios. The origins of this correlation have, so far, been lacking a conclusive explanation. Aims. We aim to find a binary evolution model which can explain the observed

Assessing vector-parasite relationship is important in understanding the emergence of vector-borne diseases and the evolution of parasite diversity. This study investigates avian Plasmodium parasites in mosquitoes collected from Kayseri province in Central Anatolian, Turkey and determines the haemosporidian parasite lineages from these mosquito species. A total of 6153 female mosquitos from 6 spec
