In the agriculture industry in the south of Sweden decreased water availability and longer growing season is expected due to climate change. By storing water resources during fall and winter, when natural water supply is high, the increased irrigation demand can be met. Stored water can be used to irrigate crops during spring and summer, ensuring food production. Longer growing season is likely to

The ideas and interests of how to move forward with the new religion and its new caliphate during the first century of Islam, were often varied and were in conflict. In the year 77 A.H (696-697 C.E.), the first Islamic Dinar was minted as a part of a wider state reform. Its abstract art and focus on language and religion symbolized the start of a new state identity that influenced a later systemat

The aim of this study was to investigate the occurrence and variation in disaster preparedness planning, for particularly vulnerable groups, in Swedish social services at the beginning of the covid-19 pandemic. The aim was also to investigate whether disaster preparedness planning, as measured in this study, had a bearing on the number of deaths from covid-19 in special accommodation and home care

Abolition theory and degrowth theory address important issues in the social-political world. An emergent discipline (in academia), abolition theory carefully dissects the ideological and historical underpinnings of the current system of police and prisons in the United States. It offers a systematic critique of their impact. Abolitionist scholars and activists also offer a creative framework for e

In 2020, Covid-19 was declared a global pandemic, which’s effects caused a crisis for society, individuals as well as the multiprofessional teams in Swedish healthcare. The aim of this thesis was therefore to explore the experience of healthcare social workers, doctors, and nurses in multiprofessional teams during the covid-19-pandemic and how this crisis has affected their collaboration. The stud

The aim of the study was to complement dual labor market research by qualitatively exploring how labor market segmentations may be understood beyond sociodemographics or inequalities of job quality. By interviewing 12 Swedish workers with wage subsidies I have found that access to high job quality may facilitate trajectories towards primary market sectors, but they are only relevant so far as the

Recent land grabs in Sub-Saharan Africa are influenced by both land availability and access to water resources beyond seasonal rains. However, much of the literature has treated land grabs and their attendant water resource appropriations as separate phenomena until recently. This paper examines the complex interplay of large-scale land acquisitions and their impacts on the water security of small

I denna studie testades och utvärderades fyra membran mot varandra för användning i högtemperaturprotonutbytesmembranbränslecell (HT-PEMFC) applikationer. En fosforsyra (PA)-dopat polybensimidazol (PBI)-membran användes som en referens som den nuvarande state-of-the-art. Laddningsbäraren i detta membran är PA, och det finns fördelar med att byta från PA till jonisk vätska (IL) som laddningsbärare In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. The charge carrier in this membrane is the PA, and there are advantages in switching from PA to ionic liquid (IL) as t

This thesis investigates the effectiveness of a water mist fire suppression system in a submarine environment. As a first step in evaluating the viability of such a system aboard SAAB submarines, the water mist was simulated using an Eulerian-Lagrangian multi-phase model in the the commercial software Star CCM+. The CFD simulation results provide a good visualisation of the distribution of the mis

In Lund, a club culture has been evolving among the city's university students, which has had a great importance on the university life. It is not uncommon for students to go out to a nightclub several times a week, particularly to Student Nations clubs. I have therefore chosen to investigate clubculture in Lund university, through participant observation and interviews. I have also decided to

This paper examines the impact of U.S. monetary policy on sovereign bond spreads in emerging market economies under the period of Unconventional Monetary Policy (UMP). Applying a Fixed effects and Pooled Mean Group method on monthly data from 2009-2020 it shows evidence that changes in spreads can be attributed to an elevated probability of emerging markets being unable to repay loans, arising fro

Skadelindringshierarkin är en vanligt föreslagen princip för att minska påverkan på naturkapital inom planprocesser. Skadelindringshierarkin innebär att påverkan på naturliga miljöer i första hand ska undvikas, annars minimeras – och när detta inte är möjligt återställas inom området eller kompenseras enligt en ekvivalens- och närhetsprincip. Beräkningarna kan utföras i en modell som exempelvis GrA commonly proposed principle for reducing impact on natural capital within the planning process is the mitigation hierarchy. The mitigation hierarchy means that impacts should primarily be avoided, otherwise minimized, and when this is not possible - restored or compensated according to an equivalency- and proximity principle. The outcome can be calculated in a model such as the Green Space Facto

Vår hjärna löser beräkningar som tar oss genom livet otroligt energieffektivt; den kör hela dagen runt på ungefär 12 watt. Jämför man med en vanlig dator som kräver ungefär 175 watt så är det inte ens nära[2]. Att uppnå hjärnans energieffektivitet är ett ambitiöst mål för dagens elektronik. Tricket ligger i att efterlikna hjärnans struktur och uppbyggnad med elektroniken. Detta forskningsområde ka

Detta examensarbete undersöker estetiska värden i arkitektur inom ramarna för cirkulär ekonomi och design. Vad som blir värdefullt när ett samhälle skiftar från vår tids globala kapitalism till ett system där evig tillväxt ersätts av ett resilient system som arbetar inom gränserna för planetens resurser. Rapporten undersöker olika källor kopplade till estetiska värden och cirkulär ekonomi och -desThis thesis examines aesthetic values in architecture within the framework of circular economy and design. The objective is to identify what becomes valuable when a society transitions from the current global capitalism to a system where perpetual growth is replaced by a resilient model that operates within the limits of the planet’s resources. The thesis analyzes various sources related to aesthe

Hard candy is hygroscopic, implying that hard candy readily absorbs moisture from the environment, resulting in adverse changes in the texture and appearance of the candy. This thesis investigates the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment. Five different hard candy formulations were exposed to an 8-day storage experiment

Using silicon nanowire (NW) arrays for solar energy conversion has gained special interest in the past years especially for their strong light interaction. The application in photocatalysis, however, requires an additional layer of protection for the silicon surface. To that end, silicon NWs with titanium nitride (TiN) coating, which exhibit a much stronger absorption than their uncoated counterpa

This thesis aims to find a design suggestion for the chassis of a new micromobility vehicle developed by the company LEVTEK SWEDEN AB by using a multiple load, compliance based topology optimization. For this purpose, 9 static load cases are suggested, 4 of which have been derived from dynamic scenarios using an equivalent static load inspired approach based on free-body diagrams. The results from

High-quality, thick III-nitride epitaxial drift layers with controlled doping are needed for next-generation highly efficient vertical power devices for a smart grid applications and electrification of mobility. Achieving desirable material properties, such as low background impurity concentrations and reduced dislocation densities in combination with high growth rates, necessary for practical app

Yatsu has both been described as an ‘abusive’ version of the nominaliser mono, as well having properties not shared with mono. In this paper, the Japanese nominaliser yatsu was examined using the written corpus Balanced Corpus of Contemporary Written Japanese (BCCWJ) created by the National Institute for Japanese Language and Linguistics (NINJAL). The research questions were as follows: “To what e

Many of the finalists selected for the NIST post-quantum cryptography project are lattice-based and rely on a Learning With Errors problem (LWE). To solve such a problem, it is possible to implement a primal attack or a dual attack. In this context, Guo and Johansson as well as the MATZOV center have both proposed an improved dual attack against several NIST lattice candidates. The goal of this t
