Lipase is one of the most useful enzymes in food industry, which can catalyze the hydrolysis and the synthesis of esters. However, the high cost due to the poor operation stability of lipase hinders the wide use of it. In present research, the stability of lipases in aqueous systems has been thoroughly studied, while research on lipases in non-aqueous systems is limited. In this work, the secondar
Low-Density Parity-Check (LDPC) codes are one of the most popular codes used in nowadays’ communication due to their high coding efficiency at low decoding complexity. With these characteristics, LDPC codes are suitable for high-speed information transmission systems. The widely used decoding algorithm for LDPC codes is Belief Propagation (BP) decoding with which the performance of LDPC codes can
Food Waste is a global issue concerning the environment, resources, social justice and economy. Despite being so pressing, around one-third of food produced is discarded worldwide. Meanwhile, food waste is incredibly complicated, requiring collaborations of all stakeholders and various innovations. Too Good To Go (TGTG) utilizes technology to bridge consumers and food business and save food waste

Stellar streams are made of stars that originate from globular clusters or dwarf satellite galaxies that have been disturbed by the gravitational pull from the galaxy they orbit. These stellar streams hold information about the history of the progenitor as well as information about the gravitational potential of the host galaxy. In this thesis we make use of the high resolution cosmological zoom s
Extremal problems in analysis have been studied for more than a hundred years. The so called Ahlfors function is the solution to one such problem. In this thesis, we shall study several properties of this function in a most general domain. We will consider the Ahlfors function in the context of analytic capacity, and also relate it to Riemann maps of simply connected domains onto the unit disk. Ou
Within recent years, the concept of Humanitarian Innovation (HI) has emerged and received growing attention within the humanitarian system as a critical means of adapting to growing complexities, uncertainties and resource scarcity. While perceived as a means of stimulating broader system changes and increasing effectiveness and efficiency of humanitarian assistance, current efforts of HI have met
Number theory is in a sense among the oldest disciplines of mathematics. A running theme is that many number theoretic problems are very easy to state and understand. However, actually solving these problems often requires much work or some very clever trick. An extreme case of this would be Fermat's last theorem: originally a conjecture by French lawyer Pierre de Fermat whose statement is und
The internet has revolutionised our world. The digital ecosphere is dominated for the most part by technology companies. The surveillance business model of these companies seeks to create predictions and inferences based on persons behaviour which can be used to shape, nudge and manipulate towards certain goals. This presents immense challenges to human rights, especially to the right to privacy.
Nepal has long been recognized as a multi-cultural country with a diverse geographical area. Despite its natural beauty, Nepal is plagued by a number of social issues. Violence against women has always been an issue, exacerbated by patriarchal cultures. Several development organisations are trying to alleviate the situation. The aim of this research is to decide how development organisations integ
Background The importance of services is increasing, and companies need well-developed service contracts to ensure the service providers perform at a satisfying level. In contracts, performance-dependent rewards (incentives) can be used to stimulate the agent to act desirably. This master thesis focuses on E.ON New Solutions B2C, who offers solar panel installations to residential customers. They
Background Transparency of a supply chain is the extent to which all its stakeholders have a shared understanding of, and access to, the product-related information that they request, without loss, noise, delay, and distortion. Having access to accurate and timely information is a challenging issue in global supply chains. Therefore, this research aimed at identifying barriers that could act as
Machine learning as a field has expanded in an explosive manner, with more companies interested in using the technology. One of these companies, Spiideo, uses Machine learning to automatically stream and record sports, highlighting key events - all automatically without a cameraman. However, these cameras have to undergo a lengthy calibration process involving manual feature extraction. This work
Politisk konsumtion är en växande konsumentrörelse där individer konsumerar inte enbart för att maximera egennytta, utan även för att skapa godartad samhällelig förändring, lokalt som globalt. Den teoretiska debatten kring detta fenomen vilar på grunder såsom neoklassisk marknadsekonomi och idén om den suveräna konsumenten. Koncept som har problematiserats och ifrågasatts i relation till denna dis
What do people residing in Hässleholm municipality really think about the sorting of their household waste? And do they understand why it`s important to sort their waste? By sorting and recycling our waste, we reduce our environmental impact. And when we do this, greenhouse gas emissions can reduce, which gives us a great environmental benefit. The goal of this study was to analyze the sorting
SVEA Medical Sport AB är återförsäljare av sportartiklar. Företaget saknade klara strategier angående beställningskvantiteter samt beställningspunkter för deras produkter och de misstänkte att de band upp mer kapital än nödvändigt. Företaget hade också problem rörande förståelse för sina restorderkostnader. Syftet med examensarbetet är att kartlägga och klargöra den faktiska orsaken till problemen
Background: The United Nations Sustainable Development Goals (SDGs) were launched in 2015 to be achieved by 2030. Goal 5 aims to achieve gender equality and empower women and girls. This study conducts a feminist analysis of gender equality concepts and data with the aim of finding adequate baseline indicators for measuring SDG 5 progress in Kenya. Methods: A convergent mixed methods research de
This dissertation serves to explain the theory behind three-dimensional scanning x-ray diffraction while at the same time connecting the theory to a software package used for processing data obtained from measurements using scanning x-ray diffraction. This software package is then used and built upon to analyse the data obtained from the measurement of a sample of 12 silica grains subject to an un
Making Europe climate neutral by 2050 is the primary goal of the European Green Deal. This goal has given rise to sustainable finance and action plans for financing sustainable growth. Such commitment is ensured by the legal initiatives put forward by the Commission. The Non-Financial Reporting Directive introduced the requirements for some firms to produce a sustainability report based on disclos
