Fruits and vegetables (F&V) waste in retail stores linked to consumer dissatisfaction has led to an increased interest in new preservation solutions to extend the shelf-life of fresh produce. In this study, the potential of controlled atmosphere (CA) combined with optimal temperature and relative humidity (RH) to extend the shelf-life of fruits and vegetables (F&V) in retail stores for sho
This thesis addresses the research problem of volatile growth and in particular economic shrinking in developing countries. A single case study of Nigeria drawing on qualitative as well as quantitative data assesses four potential factors behind the country’s frequent and high shrinking rates between 1960 and 2017. The study finds a lack of structural transformation, productivity and diversificati
Colombia committed to reduce 20% of its emissions by 2030 in the framework of Paris Agreement. The study provides a systemic approach that considers the two main drivers of the emissions in the country to know how realistic is the mentioned intended National Determined Contribution (iNDC). It analyzes deforestation and road transport with a methodology that combines analyses of their current situa
Previous research has shown a link between investor sentiment and stock market movement, as well as the correlation of search engine queries and market volatility. This research aims to extend these findings by predicting the exact firm-level daily return of Apple and Amazon. The daily returns are predicted with an artificial neural network model. In theory, this model is able to learn similarly t
More than 400 million people in the world have type 2 diabetes, making it one of the most common diseases internationally according to the World Health Organization. Thiazolidinediones (TZDs) is used to treat type 2 diabetes since it increases the sensitivity of insulin in peripheral tissues. The knowledge about the mechanism how TZD works is limited which has resulted in patients getting serious
The master thesis is a collaboration between Trelleborg AB and the division of Production and Materials Engineering at Lund University, Faculty of Engineering. The objective of the thesis has been to analyse the current production system from a lean perspective, identify an area in need of improvement and generate concrete solutions for how the studied area can be improved in terms of cost, perfor
Examensarbetet gick ut på att undersöka lösningar på PLC till PLC-kommunikation mellan olika PLC-system. Ändamålet är att lägga grund till en produkt som kan ta hand om all kommunikation mellan flera maskiner med olika PLC-system på en fabrikslinje. Detutreddes vilka kommunikationsprotokoll som var lämpliga om PLC:er från Omron och Siemens användes. Efteråt undersöktes tredjeparts leverantörers l
This study investigates the lamella settlers in Ringsjö water treatment plant, Sweden, in terms of water movement and performance. The treatment plant has two blocks with differences in the flocculation and lamella settlers, where block 1 is not able to process the maximum designed flow rate without the addition of polymers. Through data analysis the problem was confirmed, showing that the two des
The purpose of this study is to discover the characteristics of consumer brand relationships between consumers and woke brands and thus contribute to the research field of consumer brand relations. This will be achieved by looking to the relationship in the context of postmodern consumers and specifically three purposively selected cases; Pepsi, Always and Gillette. The study is based on three ca
Titel: “Jag tar aldrig av mig jobbhatten”, en kvalitativ studie om hur chefer uppfattar sin psykosociala ohälsa. Nivå: Kandidatuppsats i Service Management, VT 2019 Universitet: Lunds Universitet, Campus Helsingborg, Institutionen för Service Management Handledare: Johan Alvehus Syfte och frågeställning: Syftet med denna studie är att undersöka den organisatoriska- och sociala ohälsa som exis
The behavior of a firm to engage in international innovation collaborations is characterized by complex relations that are identified at more than one level. However, less has been done to understand multilevel interactions and the effects of the national framework conditions. In this respect, this study elaborates a comprehensive set of country and firm-level variables, including the properties o
Bakgrund: Denna studie utforskar klienter, terapeuter och handledares erfarenheter av lekmannaterapi som traumabehandling i norra Uganda. Deltagarnas erfarenheter av vad som anses vara viktigt gällande implementering, planering och kontext utforskas tillsammans med vilka möjligheter och begränsningar deltagarna ser gällande detta behandlingsupplägg. Metod: 14 semistrukturerade intervjuer genomfördBackground: This study explored the experiences of clients, therapists and supervisors in regards to lay therapy as trauma treatment in Northern Uganda. The participants’ experiences of what is important in the implementation, planning and context for such treatment setup to be successful, as well as the potentials and limitations are explored. Method: A total of 14 semi-structured interviews were
Planets that orbit their host star closely experience tidal forces due to the strength of gravity not being uniform all over the planet. This leads to effects such as tidal spin synchronization, tidal eccentricity damping and tidal semi-major axis damping. This project aims to study how the time scales for these phenomena are affected by the planetary parameters such as mass, radius and the tidal
Det pågår en ökning av skönhetsingrepp i vårt samhälle och tidigare studier tenderar att visa på samband mellan skönhetsingrepp och personlighetsdrag. Den här studiens syfte var att granska sambanden mellan självkänsla, social anpassning och skönhetsingrepp genom en kvantitativ undersökning. Studien undersökte om lägre grad av självkänsla och högre grad av social anpassning påverkar attityden tillThere is an increase in cosmetic surgery in our society and more recent studies tend to show links between beauty procedures and personality traits. The aim of this study was to review the relationships between self-esteem, social adaptation and cosmetic surgery through a quantitative survey. The study examined whether lower levels of self-esteem and higher levels of social adaption affect attitud
Denna masteruppsats studerar den nuvarande upphovsrätten inom EU och fastställer om det för närvarande finns skydd för AI-producerade verk. Det finns möjlighet att skydda verk som har blivit skapade av AI-system om det finns en länk mellan den mänskliga upphovsmannen och det slutliga verket. I detta fall betraktas AI-systemet som ett redskap för att skapa ett specifikt alster. Om länken mellan denThis master thesis discusses current copyright rules and if there is presently a copyright protection for these types of works. There is a possibility to protect works that have been generated by AI’s. However, this is only possible if a human is using the AI as a ”tool”, in order to reach a certain end-goal. There has to be a clear link between the human author and the machine, otherwise neither
The effects of a change of environment on water kefir’s microbial diversity was studied by splitting up two existing cultures (stem 1 and stem 2) among several households and culturing them for three weeks using the same method and ingredients. Next Generation Sequencing (NGS) was used on the 16S rRNA gene to identify bacterial families, genera and strains. Sphingomonadaceae, Lactobacillaceae, Ace
Collective memory is a psychological and sociological concept. This theory provides a reference for defining the characteristics of a community from the perspective of memory. Further research also shows that its internal connection to culture and community. This has many similarities with user research in product design. By focusing on typical or iconic products, objects, or the interacting proce
In this thesis a framework for finding anomalies in streaming data is proposed. The framework proposed is not necessarily applicable only to problems in anomaly detection, but could be applied to other problems as well. There are three main concepts at play in the framework: (i) Active Learning, a learning algorithm which can query a human specialist for labels of instance such that the model can
The concept of an open air drug market can be defined as a widely known area wherein public trade and use of narcotics is prevalent. This phenomenon contradicts the legislation in place regarding drug use and distribution in Sweden. This case study analyses an open air drug market located in the outskirts of Stockholm. The study specifically reviews the crime prevention methods used by law enforce
