The goal of this Master’s Thesis is to investigate the implementation of cryptographic algorithms for IoT and how these encryption systems can be integrated in a NarrowBand IoT platform. Following 3rd Generation Partnership Project (3GPP) specifications, the Evolved Packet System (EPS) Encryption Algorithms (EEA) and EPS Integrity Algorithms (EIA) have been implemented and tested. The latter are b
Lake Vomb, located in Sk˚ane, Sweden, provides water for groundwater infiltration, used for the drinking water supply of several municipalities, including Malm¨o. The lake is in a bad ecological condition with intense algae blooms during summer. Cyanobacteria dominate mentioned blooms in 2021 posing the threat of releasing cyanotoxins. The goal of this work is to asses the water quality dynamics t
LARO is a treatment method with strong scientific support, among things it is included in being considered "best practice" according to the EU's EMCDDA. However, despite the scientific support, the treatment is perceived as controversial and has received much criticism. The aim of this study was to research what professionals within LARO themselves consider to be the strengths and we
Downstream processing is an essential part in the production of biomolecules and the optimization of these processes are of great value, since they can be both time consuming and expensive. One common type of enzyme used in different biotechnical approaches is proteases and in this study Protease X was investigated. In order to use the enzyme in a process, a purification procedure needs to be esta
Structural transformation is a broad concept that has been widely argued to be of great importance for long-run economic growth. A common historical pattern highlights the labour shift out of agriculture towards manufacturing and industry sectors as the main characteristic of structural transformation. Today, large parts of the world are industrialized, as a result of a successful structural chang
Ett lokalhyresavtal kan vara ingånget för långa tidsperioder och en frågeställning för såväl hyresvärd som hyresgäst är därför om hyresrätten kan förverkas så att avtalet upphör i förtid, om hyresgästen bryter mot bestämmelser i avtalet. Anser hyresvärden att hyresgästen åsidosätter skyldigheter som går utöver jordabalken kan 12 kap. 42 § första stycket 8 JB åberopas som förverkandegrund. I denna Non-housing tenancy agreements can have long terms of agreement. It is therefore an interesting issue for the landlord and the tenant as to whether the tenancy can be forfeit or not. When the parties have specified obligations in the agreement which go beyond the Land Code, 12:42 1 st. p. 8 the Land Code is applicable. This means that the tenancy is forfeit if the tenant neglects contractual oblig
For Better or for Worse: The Influence that Individualization has had on Heterosexual Couples from an Equality Perspective. ABSTRACT Author: Julia Sellman Title: For Better or for Worse: The Influence that Individualization has had on Heterosexual Couples from an Equality Perspective.

The purpose of this study was to investigate and describe inter-professional team collaboration inside Swedish family centres. When the idea for this study formed, the impression could be gathered that family centres are depending on the professionals’ collaboration, since they are organisationally divided. One may perceive less positive consequences for the families whom are visiting the family c
Representations of librarians have appeared in popular culture for a long time. Previous research has found that the most common image of the librarian is the spinster, but only a smaller part of the research has focused on the underlying causes. Drawing inspiration from Radford and Radfords (1997) article ”Power Knowledge and Fear: Feminism, Foucault and the Stereotype of the Female Librarian”, t
A new low pressure fuel system implementation for Scania’s trucks is being investigated. The main challenge consists in exchanging the mechanical pump with electrical pumps. The electrical pumps must then be controlled to supply exactly the demanded amount of fuel at the required pressure. System redundancy allows a lot of degrees of freedom influencing the final performance. This thesis studies t
Understanding of Forster resonance energy transfer (FRET) in thin films composed of quantum dots (QDs) is of fundamental and technological significance in optimal design of QD based optoelectronic devices. The separation between QDs in the densely packed films is usually smaller than the size of QDs, so that the simple point dipole approximation, widely used in the conventional approach, can no lo
Evidence has accumulated that apoptotic cell death contributes to brain damage following experimental seizures. A substantial number of degenerating neurons within limbic regions display morphological features of apoptosis following prolonged seizures evoked by systemic or local injections of kainic acid, systemic injections of pilocarpine and sustained stimulation of the perforant path. Although
Adenocarcinoma of the small intestine (ASI) is a rare disease of unknown aetiology. The glutathione S-transferase M1 (GSTM1) enzyme catalyses the detoxification of compounds involved in carcinogenesis of adenocarcinoma of the stomach, colon and lung, including constituents of tobacco smoke. We investigated a possible interaction between the lack of GSTM1 enzyme activity and the carcinogenic compou
BACKGROUND: We have performed a prospective qualitative investigation of the ICU syndrome/delirium; the main parts of which have recently been published. The aim of the present study was to explore the relationship between the ICU syndrome/delirium and age, gender, length of ventilator treatment, length of stay and severity of disease, as well as factors related to arterial oxygenation and the amo
Africa is a sink of carbon, but there are large gaps in our knowledge regarding the CO2 exchange fluxes for many African ecosystems. Here, we analyse multi-annual eddy covariance data of CO2 exchange fluxes for a grazed Sahelian semi-arid savanna ecosystem in Senegal, West Africa. The aim of the study is to investigate the high CO2 exchange fluxes measured at the peak of the rainy season at the Da
Expanding service coverage and achieving universal health coverage (UHC) is a priority for many low- and middle-income countries. Though UHC is a long-term goal, its importance and relevance have only increased since the start of the COVID-19 pandemic. The first step on the road to UHC is to define and develop essential packages of health services (EPHSs), a list of clinical and public health serv
Background: This study investigates the possible benefits of radiofrequency ablation (RFA) in patients with non-resectable colorectal liver metastases. Methods: This phase II study, originally started as a phase III design, randomly assigned 119 patients with non-resectable colorectal liver metastases between systemic treatment (n = 59) or systemic treatment plus RFA (± resection) (n = 60). Primar
Some network cameras have already several other sensors besides the image sensor to extend the capabilities of the camera. It is then only natural to think what can be achieved when air sensors are added into the mix. In this master thesis the applications of air sensors coupled together with network cameras have been investigated. Considering the network infrastructure is already in place, having
Multinationella företag har, på grund av den ökade globaliseringen, i allt större utsträckning börjat etablera komplexa leverantörskedjor vilka inte sällan sträcker sig över olika världsdelar. Produktionen förläggs framförallt i utvecklingsländer där efterlevnaden av arbetsrättsliga standarder många gånger är bristfällig. Allt eftersom kritik riktats mot multinationella företag har en insikt om etMultinational companies have - due to the increased globalisation - started to establish complex global supply chains to a greater extent, ones who often reaches to different parts of the world. In particular, the production gets placed in third world countries where the observance of labour laws many times are inadequate. As critical voices have spoken up against these multinational companies, th
