The research is done in order to analyse management of waste beverage containers in Belarus and the effectiveness of policies implemented to address it. The analysis is followed by exploring whether the introduction of deposit-refund system (DRS) would help to address packaging waste issue in Belarus and, if so, what features the DRS should possess to be effective in current context. The study des

Världens sötvattensystemen är sårbara och har upplevt betydande miljöförändringar. Utöver direkt mänsklig påverkan, innebär klimatförändringar ytterligare påfrestningar på våra färskvattenresurser. I denna studie undersöks hur klimatförändringar har påverkat tidsperioden av istäckning i svenska sjöar och vattendrag. Observationer från över 750 sjöar och vattendrag i Sverige har analyserats, med viThe worlds freshwater systems are vulnerable and have experienced significant environmental changes. In addition to direct anthropogenic impacts, climate change poses yet another source of pressure on the freshwater resources. This study investigates climate change impacts on ice cover duration in Swedish lakes and rivers. In situ observations from over 750 lakes and rivers in Sweden were analyzed

Vattenkraften står för hälften av vårt elbehov i Sverige idag. Merparten av vattenkraftverken är gjutna i betong och som många andra betongkonstruktioner så drabbas betongen av sprickbildning av olika orsaker. För vattenkraften är genomgående sprickor ett problem då dessa skapar läckage. För att förhindra dessa sprickor har en ny metod börjat undersökas där bakterier som kan avsätta kalciumkarbonHalf of the electricity needed in Sweden today is produced by hydro power. Most structure parts in hydro power stations are made of concrete and as many of other concrete structures they contain cracks. Cracking through dams are a big problem for hydro power since they create leakage. To prevent cracking a new method is under investigation. It consists of incorporating calcium carbonate precipita

China’s women’s movement is currently being reignited by diverse groups of young feminist activists. Given China’s authoritarian environment, these activists have condemned institutionalized efforts to achieve gender equality and instead adopted a noninstitutionalized approach through performance art, such as theatre and singing. This year marks the 20th anniversary of the 1995 Beijing Women’s Con

Previous studies have shown that increased incorporation of odd chain saturated fatty acids (OCFAs) into plasma phospholipids is associated with a lower future risk of developing type 2 diabetes and that decreased levels of OCFAs are linked to increased insulin resistance. Since the β-cell plays a pivotal role in the progression of type 2 diabetes it is of interest to investigate if elevated level

In recent decades, there has been significant attention on the decline in insect populations, including moths and hover flies. To tackle this issue, innovative methods such as entomological LiDAR technology have revolutionized the remote identification of free-flying insects. The distinct spectral reflection from moth and hover fly wings enables precise differentiation between species and sexes. W

The present study investigated the relationship between excessive social media usage in everyday life and autobiographical memory recollection. Previous studies have investigated the effect of social media on autobiographical memory in terms of distinct events, while research regarding the cumulative effect of this is lacking, which is the main focus of the present study. This was investigated by

The European Spallation Source ESS, under construction in Lund, Sweden, aims to produce high-brightness and intensity neutrons for a multitude of experiments upon completion. An efficient production of neutrons requires elaborate understanding of the moderation process which slows the neutrons from relativistic speed to a kinetic energy of meV. The moderator used at the ESS will be partially made

The demand for alternative sources of protein has increased; the so-called “protein shift” is an inevitability. Mycoprotein, a foodstuff produced from the mycelium of filamentous fungi, has gained popularity among consumers. Mycoprotein is grown in submerged culture, in either a simple or a complex, undefined medium. Strategies for yield increase in either medium were studied in this paper. For s

The rapid diffusion of mobile phones and the internet in Kenya is hoped to be an effective solution to meeting the crucial information needs of smallholder farmers to improve their economic and environmental resilience. This thesis conducts a case study based on interviews with actors who provide digital agricultural extension services to farmers in Kenya to assess the Agricultural Innovation Syst

As a consequence of the COVID-19 pandemic and the resulting restrictions, many companies found themselves in the reality that they had to conduct their business operations from home. The pandemic has heightened the need for Professional Service Firms (PSFs) to shrink, pivot, re-invent themselves, as well as redeploy organisational culture and resources dramatically, abruptly, and possibly disrupti

During steady state, the intestinal immune system functions to maintain the bowel’s physiological function in the face of constant bombardment by environmental materials (potentially infectious agents, commensal bacteria and foreign proteins). Immune responses thus maintain a delicate balance between immunogenicity against harmful invading pathogens and tolerance of the harmless diet and commensal

Most of today’s materials show either high strength with low ductility, or relatively low strength combined with high ductility. It is strongly desired in the industry to obtain materials whose mechanical properties can display a combination of high strength and elongation. That is why the new concept of harmonic structure has been introduced recently. This structure consists of strong ultrafine g

The purpose of this thesis is to examine the views of internet stakeholders in Sweden, from the perspective of net neutrality. There does not exist one single definition of the principle, which makes defining net neutrality in the context of this thesis important. The basic concept of net neutrality is that all similar internet content should be treated equally. However there are several technical

This thesis examines the shareholder value creation of IP in M&A. Using a unique patent-M&A data set over the period 2006 to 2016, we show that acquirers of companies holding IP gain significantly more shareholder value than acquirers of targets not holding IP. We find that this only holds as a binary relationship, and that the discrete relationship between shareholder value and IP is nega

This thesis describes the characterization of the rheological properties of dense suspensions of sodium caseinate and micellar casein with respect to changes in concentration (100-200g/L), pH (7.0-5.3), charge density (Δα), and temperature (5-40°C). The relationship between pH and charge density and how this relationship is affected by changes in temperature and concentration were also addressed.
