The sample under study consisted of 13,205 observations from mothers in all regions of Peru and their children aged 1 to 5

The aim of this thesis was to deepen the understanding of brand activism by looking into existing and novel dimensions on which consumers base their validation and opinion of brands engaging in socio-political discourse. This dissertation followed a dual-analysis approach in which both qualitative and quantitative research was conducted. This study drew on socio-political activism theories, consum

Forests form the backbone of the European terrestrial carbon sink (State Forest Service & Ministry of Environment, 2018). As the European Union (EU) strives to become climate neutral by 2050, forests are accounted for the natural carbon absorption mechanism (European Commission, n.d.). Currently, the European net land carbon sink is decreasing largely due to forest ageing (Pilli et al., 2022),

With the large expansion of renewable energy sources such as wind- and solar, the stability and quality of electrical power can be affected. The transition towards large-scale wind power offers many opportunities to maintain stability by using power converters to create synthetic inertia. At request of Sweco Energy, this thesis shows the effect and importance of synthetic inertia used in wind powe

In the past years, Sweden had been facing rapid growth of photovoltaic cells and total PV installation capacity increased from 300 kW to 1090 MW (2006-2020). To increase the number of PV users and therefore assist in achieving multiple sustainable goals regarding renewable energy, the installations of such systems were actively supported by the Swedish government. This project is aimed at evaluati

Norge behöver utöka sin elproduktion för att möta ett framtida ökat elbehov. Vattenkraften i Norge uppskattas endast ha 23 TWh kapacitet kvar att bygga ut och vindkraft har mött starkt motstånd på senare tid. Solkraft finns fortfarande bara på liten skala i landet men uppskattas öka kraftigt i närtid. Solkraft installeras hela tiden längre norrut men än finns ingen storskalig solkraft i norra NorgNorway needs to increase its power production to meet the future increase in electricity use. Hydro power is estimated to only have 23 TWh of additional available capacity and wind power has met strong resistance lately. Solar power is still only implemented on small scale in Norway but is predicted to increase rapidly in the near future. It is steadily being implemented further north, however the

The number of irregular migrants increased in Turkey, especially after the EU-Turkey Joint Action Plan of 2016. This study examines the situation of undocumented Syrian migrants in terms of their capabilities and approaches to the well-being of this particular group from the normative framework of the capability approach with a specific focus on material conditions. Building on the Capability Appr

The iron-chromium (Fe/Cr) catalyst is used for high-temperature water-gas shift (HT WGS) reaction. A major concern using the Fe/Cr catalyst is that it contains hexavalent chromium (Cr+6) which is a potent carcinogen causing health and environmental issues. In order to reduce the usage of chromium in industrial HT WGS applications, a chromium-free catalyst needs to be developed. The aim of this theAs energy demand increases worldwide, the interest in hydrogen has increased as well. Hydrogen is an excellent energy source and an essential component in large industries such as oil refineries, ammonia production plants and methanol synthesis plants. To produce hydrogen, steam methane reforming process is used where methane (CH4) and steam (H2O) is converted to carbon monoxide (CO) and hydrogen

Att använda sig av så kallad GPS-baserad probedata i syftet av att validera trafikmodeller är en relativt ny och oprövad metod. Insamling av GPS-baserad probedata sker genom att fordon registrerar sin lokalisering vid flera punkter utmed sin resa. Metoden har potentialen att effektivisera och förbättra arbetet med att producera verklighetsförankrade och pålitliga trafikmodeller. Men för att nå ditIn traffic assignment, one of the key elements is the validation process. The validation allows the traffic planner to get an understanding of whether the model is working according to reality-based metrics, or if it must be improved. There are several different ways of collecting reality-based metrics, one these methods are called GPS probe data. Through this study, a survey as well as a case stu

15% of all five year olds and 5-10% of all 7 year olds struggle with bedwetting, a condition medically known as enuresis. Current treatment methods rely primarily on the family to carry out an 8 week treatment. In order to involve healthcare providers in the process and create an opportunity for individualized treatments, Pjama AB has developed an enuresis alarm system. This system directly shares

Färskvatten av god kvalitet och kvantitet är avgörande för mänsklig överlevnad och livskvalitet. För att ta vara på befintliga vattenresurser vid vattenbrist kan renat avloppsvatten återanvändas. Simrishamns kommun i östra Skåne upplever redan idag vattenbrist och återanvändning av vatten genom konstgjord infiltration övervägs därför. Syftet med det här arbetet är att klargöra den kemiska kvalitetSufficient quantity and quality of fresh water is crucial for human survival and quality of life. Water resources in water scarce areas can be efficiently managed by water reuse. In the Swedish municipality of Simrishamn, water scarcity is already a fact. Therefore, indirect water reuse by artificial infiltration is considered. The aim of this project is to examine the chemical quality and thereby

Bakgrund I en åldrande befolkning ökar risken att utveckla neurodegenerativa sjukdomar. Begreppet neurodegenerativ sjukdom är ett samlingsbegrepp för många olika sjukdomar som har gemensamt att de påverkar neuronerna i hjärnan. Om dessa neuroner skadas eller dör kan kroppen inte ersätta dem, vilket gör att sjukdomarna som omfattas inte går att bota, de innebär funktionsnedsättningar för individen

Du kanske aldrig har funderat på vattnet som kommer ut ur kranen? Till diskmaskinen, matlagningen, duschen eller vattenspridaren? Rent dricksvatten är något vi tar för givet, men trots det har sjön som förser stora delar av sydvästra Skåne med dricksvatten omfattande miljöproblem. Vombsjön är belägen mitt i Skånes jordbrukslandskap där näringsämnen läcker från åkermarker och små avlopp. SjönsClean drinking water is often taken for granted. However, the lake that supplies the greater part of southwestern Scania with drinking water has severe environmental problems regarding the chemical and ecological status. The organization Fokus Vombsjön has now taken it upon themselves to develop a water management plan for the lake, with the goal to improve its overall status. The aim of this s
