The lifetime extension of smartphones is seen as a prominent way to reduce the environmental impacts caused during the production of the devices. Smartphones may be small devices, but their impact is no longer small as for the past years e-waste has been the largest growing waste generated globally. This research aimed to learn what perspectives Swedish smartphone users had towards repairability a
With the introduction of millimeter-wave antenna arrays in 5G base-stations and ever-increasing data volumes, the power consumption of the signal processing in digital radio systems has increased over the last decade. This, combined with increased cost and environmental awareness, has put focus on power optimization. This thesis investigates different aspects of optimizing one important component
Given a set N with n elements and a family F of subsets, we show how to partition N into k such subsets in 2(n) n(O)(1) time. We also consider variations of this problem where the subsets may overlap or are weighted, and we solve the decision, counting, summation, and optimization versions of these problems. Our algorithms are based on the principle of inclusion-exclusion and the zeta transform. I
Backgrund Product development (PD) in the plant breeding industry is characterized by long development cycles and decisions framed with uncertainty concerning key questions such as likely future competitor actions or the market outlook 10-15 years from now. In many ways the contemporary picture of the industry is changing rapidly; new technologies are developed to shorten the length of PD cycles a
OBJECTIVE: To evaluate, in patients stimulated with recombinant FSH and GnRH antagonists, whether triggering the final maturation of oocytes affects IVF outcomes.STUDY DESIGN: Five hundred and six IVF procedures were divided into three groups according to the timing of hCG administration: when at least 2 follicles reached the diameter of 17 mm, at least 2 follicles reached 18 mm and at least 2 fol
ObjectivesThe main objective of this study was to derive cost estimates of five major foodborne illnesses (campylobacteriosis, salmonellosis, enterohemorrhagic Escherichia coli (EHEC), yersiniosis and shigellosis) in Sweden. These estimates provide a necessary contribution to perform future cost-benefit analyses aimed at reducing the burden of foodborne disease. A secondary aim was to obtain estim
Background: The adoption of eHealth accelerated during the COVID-19 pandemic. Inequalities in the adoption of eHealth during the COVID-19 pandemic have been reported, but there are few such studies among people with impairment. Objectives: This study aimed to investigate self-reported use and difficulty in the use of eHealth before the COVID-19 pandemic compared to during late social distancing re
Background and aim The paper is based on a study of hunting tourism enterprising in Sweden. The paper demonstrates how game meat is ascribed different, sometimes conflicting values in the moral economy of commercial hunting and identifies an emerging process of servitization of the game meat. Recreational hunting in Sweden can be described as embedded in two different but overlapping cultural and
Biologisk mångfald i urban miljö har visats sig ha stor betydelse för människans rekreation och fysiska och psykiska hälsa. Samtidigt förbättras stadens hälsa genom de bullerdämpande, luftrenande och klimatförbättrande egenskaper som vegetationen har. Syftet med denna undersökning är att utföra en temporal och rumslig analys med avseende på antal och utbredning av rödlistade kärlväxter i GöteborgsThe importance of green areas in urban environment has over the last decades, become more and more evident. The physical and psychological health of people is improved by having green and diverse surroundings. Positive effects from vegetation for the city itself are for example, improved air quality and climate. The aim of this study was to investigate temporal and geographical changes of red list
An Auditing Tool for Climate Effective PackagingAssociate Professor Henrik Pålsson and Associate Professor Daniel Hellström of the Packaging Logistics department of Lund University was awarded first a Pathfinder and then a partner accelerator project from Climate-KIC. The project aims to strengthen and improve the quality of packaging audits for decreasing the total climate impact of packaging. Th

Existing research on graffiti has been preoccupied with the tension between the legal and illegal aspect of the subculture, instead of pursuing the 'where,' 'how,' and 'why' of graffiti as defined by graffiti writers themselves. Erik Hannerz takes such issues as his project's starting point, relating them to how graffiti writers perceive, interpret, and act upon public space as well as the measure

A transcription of the fourth episode of season three. Nic: This is the 4th and final episode of this very short third season of the Meridian. Crossing our local Meridian today we have Professor Marie Dacke visiting us from the Department of Biology where she is part of the Land Vision group studying nocturnal animals and how they navigate using stars. Later in the episode, we will also bring y
