Då städerna förtätas blir det alltmer aktuellt att förlägga anläggningar under marken. För att få åtkomst till underjorden, vid t.ex. ett tunnelbygge, så konstrueras vertikala åtkomstschakt, se Figur 1. För att förhindra att schaktet rasar samman så används någon form av stödkonstruktion för att hålla emot det horisontella jordtrycket. Den geometriska utformningen av stödkonstruktionen kan på olikUrbanisation is causing densification of cities and more and more facilities are being placed in the underground to utilise the urban space as efficiently as possible. Access to the underground is obtained by constructing vertical access shafts. By constructing the shaft with a circular plan geometry, an effective construction is obtained which can carry large earth pressure loads by utilising the

This study aimed to investigate on the employees in new ventures and focused on the perceived person-job fit and person-organization fit among staff members working in Swedish and Danish start-ups. Additionally, this study intended to understand how the perceived fit affects the employees’ job satisfaction and turnover intention. Moreover, this research was interested to see whether the start-ups

Detta arbete har som syfte att identifiera de tekniska och organisatoriska faktorer som inverkar då molntjänster implementeras och används i små företag. Uppsatsen är baserad på en litterär undersökning samt en empirisk studie i form av en kvalitativ undersökning. Den kvalitativa undersökningen grundas i fyra intervjuer med IT-kunniga informanter som alla utför sitt arbete med hjälp av molntjänste

This thesis investigates the effect of commuting time on labour supply using US household survey data. To circumvent biased estimates as working hours and commuting time are jointly determined by the worker, a first differences approach is carried out, in which changes in the commute are assumed to be exogenous. The estimates suggest that there is no causal effect on labour supply that can be deri

The aim of this study is to further understand the usage of cultural values to affect Generation Z and how the values connected to the generation, defined by earlier researchers, is used to create brand authenticity. Generation Z is known as an honest and value driven generation who has grown up with the internet as a part of their lives. The study is based on Hedvig, a Swedish insurance company w

Biogas has been acknowledged as one of the most important aspects for sustainable development. It is a renewable energy technology being promoted especially in developing countries for poverty reduction and climate change action. Despite concerted efforts to alleviate poverty, production and adoption of biogas remains very low in Zambia, and they prompt some questions: How do institutional, situat

The estimation of a country’s greenhouse gas emissions has appropriately calculated the total footprint of a nation. However, when such estimates are brought down to the level of each economic activity, they do not reflect the total consumption pattern of a sector by not taking intersectoral relationships into account. Therefore, this study has two major purposes: (1) to estimate the greenhouse ga

Women’s political representation in Zimbabwe has been low since independence in 1980. Studies on women’s access to political decision-making, representation and agency in Africa, including Zimbabwe, is limited. Therefore, this dissertation aims to contribute to localized and contextualized knowledge on the barriers for women’s political representation through a case study of the 2018 harmonised el

ndia ranges among the countries experiencing most water stress in recent years, while being a major virtual water net exporter. The country’s position relative to its water sources exacerbated since its trade liberalization in the early 1990’s, which calls for a future national water crisis. To comprehend India’s water stress, this study aims to examine the country’s agricultural water use at thre

Peptider är mindre versioner av protein. Det som man vanligtvis kan läsa på innehållsförteckningen på de flesta matvaror i dagen samhälle. Peptiderna i sig består av aminosyror som kan anses vara de minsta byggstenarna för peptider och proteiner. Peptider och proteiner spelar en stor roll i våra biologiska system. Proteiner och peptider bidrar till flera viktiga processer. Proteiner hjälper till mUnderstanding of the self-assembly behaviour of peptides is of great interest within several different areas such as neurodegenerative diseases, biotechnology, and peptide pharmaceuticals. In this work we have compared the impact on the self-assembly behaviour derived from systematic changes of the primary structure of A8K, where A denotes alanine and K lysine. Model peptides derived from A8K incl

The intersectional analysis was applied in a sociological study on the arguments of the legalization of prostitution in Ukraine and the characteristics of the main actors of media discourse. The theoretical rationale for the discourse on the phenomenon of prostitution was the application of Margaret Archer's structural-activity approach and the concept of intersectionality, to describe and exp

Yearly thousands travel from around the globe to Peru to participate in the ceremonial consumption of ayahuasca under the guidance of a shaman. The brew stimulates a psychedelic state in users that triggers hallucinations, powerful emotional responses,and severe physical reactions, all of which are codified into ritual practice. Drawing from ethnographic material gathered from one month of field w

This paper aims to investigate the causal relationship between maternal education and preventive behaviour. For this purpose, I consider the education reform implemented in Zimbabwe in 1980 that enabled students at age 15 and below to participate in secondary education. By using this age cutoff as an exogenous exposure to the education policy, I obtain causal estimates of schooling on health outco

The thesis aims to explore the role of movements in elaborating alternative development. Through the qualitative approach, the study investigates the Development Justice movement in the Asia Pacific region as a case study. The document analysis and semi-structured interview reveal how the movement had built and formulated its demands in relation to mainstream development. The study is theoreticall

Forced air convection systems are the most preferred design of choice in many of the industrial-scale convection ovens. In this study, experimental investigation on convective heat transfer and mass transfer within a forced air convection oven was performed at different oven temperatures (100℃, 110℃ and 120℃) and at flow velocity (2 m/s, 3 m/s and 4 m/s) using potato slices (10*10*60 mm) as model

Då samband mellan derivata och integral är ett viktigt koncept inom avancerad matematik är det avgörande att gymnasieelever får goda möjligheter att lära sig detta. Faktumet att läroböcker ofta intar en central roll i den svenska matematikundervisningen har lett fram till ämnesvalet för min studie, vilket utgörs av en undersökning av hur detta samband presenteras i tre läroböcker i matematik. Fors

The objective of this study is twofold. First, the research tries to address whether the selected 13 African countries have gained a comparative advantage on labour-intensive industry (i.e. textile and apparel sector) for the period 1995-2017. The study employs Balassa’s Revealed Comparative Advantage (RCA) indices to address this objective. Second, it attempts to investigate whether there is an e

Central to the field of agrarian political economy, is rural development and capitalism’s advancement in the countryside and its consequences for the peasantry, ‘the agrarian question’. With the present case study, I examine the interplay between social relations of production and agrarian change in eastern Bolivia. Using the case study of Ramada, a small indigenous community, this dissertation in

It is a huge challenge for any strategic communicator to reach its audience as they are constantly overwhelmed with information. A current trend is to create so-called deepfakes, where a photo, audio, or video can be manipulated while making it feel authentic. Although it is an effective way to engage and entertain that has become increasingly popular, it has also received a lot of criticism as it
