Populärvetenskaplig sammanfattning Långsiktig morfologisk utveckling av Cua Lo mynning i centrala Vietnam - En processbaserad numerisk modellering Nikita Tegenfeldt Orio Johansson En matematisk modell utvecklades för att beskriva hur en flodmynning i centrala Vietnam kommer att flytta sig längs med kusten och hur bredden förändras från nu fram till 2050. Mynningen kopplar ihop havet med en lagCua Lo river mouth is a coastal inlet connected to an estuary at the central coast of Vietnam. The area is valuable for maritime trade, fishing industries, and tourism development. Natural disasters during the monsoon period are a problem, causing seasonal flooding. In connection to the inlet lies an elongating sand spit which causes erosion and destruction of residential areas on one side of the

Föreställ dig att du kunde producera vatten från luft, eller ha arean av en fotbollsplan i ett gram pulver. Det är två utav många fenomen som syntetiska metall-organiska ramverk (MOF) kan åstadkomma eftersom de ofta besitter kristallporer i storlek av nanometrar. Denna studie fokuserar på att kapsla in katalysatorer i MOF:ars porer. Sådana ramverk kan kallas catalyst@MOF och syftet är att lätt kunMetal-organic frameworks (MOF) are hybrid organic-inorganic porous materials with a crystalline framework. The MOF frameworks contain specific nano-sized pores that can be used for gas storage, gas separation, drug storage, luminescence sensoring, artificial photosynthesis, drug delivery, catalysis etc. The aim of this study was to encapsulate three diiron hexacarbonyl and one Ni(II) catalysts in

Pentaklorfenol (PCP) är en klorerad aromatisk förening som användes flitigt för att behandla trä mot mikrobiell nedbrytning innan den blev förbjuden på 70-talet. På grund av dess höga löslighet förekommer PCP som en grundvattenförorening kring äldre sågverk. Hjortsberga i södra Sverige är ett exempel på denna typ av förorening och är det område som undersöks i arbetet. Förorenat grundvatten spridsPentachlorophenol (PCP) is a chlorinated aromatic compound that was commonly used for treatment of wood against microbial degradation before it got banned in the 1970s. Due to its solubility in water, PCP is a common groundwater contaminant around old sawmills, for example near Hjortsberga in southern Sweden where this study was performed.. The contaminated groundwater is spreading and leaking int

Vi har i vår studie undersökt hur chefer talar om och beskriver motivation i arbetssammanhang. Vi har även studerat hur den egna förståelsen av motivation återspeglas i hur chefer resonerar kring och arbetar med andras motivation. Våra forskningsfrågor var följande: Hur reflekterar och talar chefer kring motivation i arbetssammanhang? och Har den egna uppfattningen av motivation någon betydelse el

The low-carbon benefits and emissions savings from circular economy (CE) strategies are not yet well understood, yet are crucial for global development within Planetary Boundaries. Using the mineral fraction of waste incinerator bottom ash (MIBA) as construction material in road construction is one application of a CE strategy that could lead to environmental gains by substituting energy-intensive

This explorative case-study examines the dynamics of operationalizing climate change adaptation (CCA) measures in the aftermath of climate change induced natural disaster at the community level in a low-lying coastal Nation State with fragile institutional capacity. It explores the roles and responsibilities different stakeholder groups take and identifies constraints and facilitators for operatio

This thesis focuses on the case study over the Kävlinge catchment located in the south of Sweden, and mainly in the Kävlinge river. This river, which is the mainstream of the catchment, has been subject to modifications due to agricultural activities. Such modifications, like straightening or increasing the depth and channeling sections of the river, will affect the river’s hydrodynamics. These in

Denna avhandling beskriver syntes av en fem-koordinerande ligand och järnkomplex av denna nya ligand. Järnkomplexen har syntetiserats med syftet att framställa katalysatorer som kan härma reaktiviteten hos järnoxygenas-enzymer. Denna typ av enzymer katalyserar mängder med viktiga oxidationsreaktioner. För att enzymerna ska kunna utföra dessa essentiella oxidationer har ett högvalent Fe(IV)-oxo intThe pentadentate ligand 2-(pyridine-2-yl)-N,N-bis(pyridine-2-ylmethyl)quinoline-8-amine was isolated and characterized. Mononuclear iron(II) complexes of the ligand have been synthesized and characterized. Three iron complexes, [Fe(CH3CN)L1][OTf2], [Fe(OTf)L1] and [Fe(Cl)L1][Cl6Fe2O] (L1 = 2-(pyridine-2-yl)-N,N-bis(pyridine-2-ylmethyl)quinoline-8-amine) (OTf = triflate, trifluoromethane sulfonate)

The concept of industrial symbiosis (IS) provides practical solutions for resource efficiency and low-carbon development. The IS represents a collective, multi-industrial approach for companies to improve their economic and environmental performance through the sharing of heat, electricity, water, by-products, information, and reuse of waste. The main challenges to IS emergence include a long dura

Dibenzo[a,e]cyclooctatetraene or dbCOT is a commonly used ligand in transition metal catalysis. Moreover, the Strand group has been using its properties to change shape (from tub-shaped to planar and vice versa upon reduction/oxidation) to develop novel molecular machines. However, the use of dbCOT in both transition metal catalysis and as a building block for molecular machines has been limited b

Denna uppsats utreder huruvida det går att identifiera en särskild rättsordning vad gäller fördelningen av internationellt ansvar mellan EU och dess medlemsstater under blandade avtal, det vill säga internationella avtal som undertecknats av EU och vissa eller alla dess medlemsstater på ena sidan, och en tredje stat eller internationell organisation på den andra. Uppsatsen presenterar slutsatsen This thesis examines whether there exists a special legal regime for the apportionment of international responsibility between the EU and its Member States under mixed agreements. The thesis argues that the sui generis aspects of the EU, such as its constitutional order, its international legal personality, its extensive treaty-making powers, legislative powers, its executive federalist construct,

In this thesis I examine the metapolitics of the French far right, a sphere of organisations and personalities that are waging a counter-hegemonic cultural fight, thought to be a precondition to political change. In France, singularly an incubator for a green nationalist narrative, this “Gramscianism of the right” is today embodied by countless media outlets. This research, grounded in a socio-con

Geologisk tid är inte bara ett tröskelbegrepp, det är en central del i hur vi erfar geovetenskapliga fenomen som utspelar sig på en rumtids-skala som sträcker sig från mikro (exempelvis molnbildning) till makro (exempelvis plattektonik). Om vi vill förstå geovetenskapliga fenomen måste vi gå från det konkreta till det ab-strakta, vi måste gå från att kunna se och ta på fenomen till att enbart kunnGeologic time is more than a threshold concept, it is a central part of how we experience geoscientific phenomena that takes place on a space and time scale ranging from micro (e.g. cloud formation) to macro (e.g. plate tectonics). If we want to understand earth science phenomena, we must move from the concrete to the ab-stract, we must go from being able to see and touch a phenomenon to being abl

This essay explores which sector of the Swedish economy has benefited the most from changes in the exchange rate during the period 1997-2018, which was a time of depreciation. Branches from two-number SNI (Swedish National Industrial Classification) are categorized into three main sectors: services, primary industry and remaining industry, and then matched with SITC data on imports and exports. It

Since the 1950’s, a wide range of titanium alloys has been developed. Attractive titanium properties are the high strength-to-weight ratio, resistance towards corrosion, low thermal conductivity and low thermal expansion. Properties that make titanium alloys difficult-to-machine materials are those of low thermal conductivity, chemical reactiveness and the high strength, requiring low cutting data

Based on fieldwork interviews from two different trade unions in Luanda, this study aims to reflect on the role of civil society for the consolidation of democracy in Angola, and in particular, the challenges of trade unionism and its effects on democracy. Using the meth-od of inductive reasoning to process data, it first addresses themes derived from the inter-views such as Financial struggles, T

Denna syftar till att undersöka de argument som Obama-administrationen uttryckte angående ett amerikanskt militärt ingripande i Syrien till följd av de syriska regimens användning av kemiska vapen år 2013. Under sitt presidentskap uppgav Obama att USA drar en "röd linje" vid användade av kemiska vapen mot civila, men hotet visade sig vara tomt ett år senare när tusentals människor dödadeThis paper aims to examine the arguments proposed by the Obama administration regarding a U.S. military intervention in Syria due to the use of chemical weapons by the Syrian regime in 2013. During his presidency, Obama stated that the He draws a ‘red line’ at the use of chemical weapons against civilians, but the threat proved to be empty a year later when thousands of people were killed in a che

The current debate concerning land acquisition for commercial agriculture is whether it can contribute to poverty reduction by developing communities through successful agribusiness, or whether it leads to dispossession of traditional land users. Thus, this research is a case study of the African Agricultural Development Company (AgDevCo) and their irrigated farming hub in Babator, Ghana. It will
