Solar power clearly has one of the greatest potential among renewable energy but a big setback is that it is still relatively expensive. Engineering of materials on a nanoscale, e.g. the growth of nanowires makes it possible to make semiconductor-materials with better optical properties while using less material than for traditional bulk semiconductors. This means that nanowire based solar cells h
Mögel som växer inomhus har påvisats orsaka ohälsa som andningsbesvär, allergi och eksem. Eftersom vi tillbringar större delen av våra liv i inomhusmiljöer är det viktigt att hitta lösningar på detta problem. Eftersom det finns mögelsporer i luften och går det inte att undvika att få in dem i våra byggnader. Det som går att göra är att förhindra sporerna från att gro. Syftet med detta projekt har Mould growing indoors has been shown to cause health problems such as respiratory disorders, allergies and eczema. Since we spend most of our lives in indoor environments, it is important to find solutions to this problem. As mould spores are present in the air one cannot avoid getting them into buildings, but it is possible to prevent the spores from germinating. The purpose of this project was t
DPM is a manufacturing company within the metal cutting industry. A number of years ago there emerged a desire to make statistical calculations for its production. Until today, the company has not done any post-calculations, which means that they have based their cost calculations and sales prices on precalculated costs. The absence of post-calculations leads to lack of cost-consciousness that is
Aktieägaravtalet är ett populärt komplement till de vanliga aktiebolagsrättsliga styrdokumenten. Det syftar till att ytterligare reglera aktieägarnas mellanhavanden och associeras med en rad kommersiella fördelar så som avtalsfrihet och konfidentialitet. Däremot har aktieägaravtalets bolagsrättsliga verkningar under många år varit föremål för diskussioner. Den gängse uppfattningen har länge variThe shareholders’ agreement is a popular complement to the articles of association. It seeks to further regulate shareholders' dealings and is associated with a range of commercial advantages such as freedom of contract and confidentiality. However, the company law implications on the shareholders' agreement are still subject for discussions. The prevailing view has long been that the sha
The purpose of this thesis was to lead daylight in to a hallway in a terraced house in Gunnesbo outside of Lund, and to find out which method will give the best lighting results. It is known that daylight have a positive effect on health and wellbeing; it controls the circadian rhythm, increase performance and reduce the risk of suffering of such as depression and type 2 diabetes. The light that c
The aim of this study was to examine the aspect of power in the relationship between the personal assistant and the disabled person he or she works with (the user). The study was based on interviews with five personal assistants who worked for private companies that provided personal assistance. Seven themes were identified and discussed. These were: the users amount of control over the assistance
In today's ever changing business world, the competitiveness of organizations relies on employees' competencies, which entails the fact that employees' contributions become more valuable than ever before. The main purpose of the study was to identify which strategies are used by successful employees at Corporate Market in Síminn (an Icelandic company which handles telecommunications) i
The natural products pulchrol and pulchral, isolated from the roots of the Mexican plant Bourreria pulchra, have previously been shown to possess an antiparasitic activity toward Trypanosoma cruzi, Leishmania braziliensis and L. amazonensis, protozoa responsible for the Chagas disease and leishmaniasis. These infections have been classified as neglected diseases, and still require the development
A number of virtual reality head-mounted displays (HMDs) with integrated eye trackers have recently become commercially available. If their eye tracking latency is low and reliable enough for gaze-contingent rendering, this may open up many interesting opportunities for researchers. We measured eye tracking latencies for the Fove-0, the Varjo VR-1, and the High Tech Computer Corporation (HTC) Vive
Background: Parents of children with complex right ventricular outflow tract (RVOT) anomalies are con-fronted with their child’s need for heart surgery early in life and repeated reoperations later on. Preoperative assessment needs to be performed whenever an indication for reoperation is suspected. The aim was to illuminate the experiences of parents of children diagnosed with RVOT anomalies, in
Sivakumar et al. (2000a), by employing the correlation dimension method, provided preliminary evidence of the existence of chaos in the monthly rainfall-runoff process at the Göta basin in Sweden. The present study verifies and supports the earlier results and strengthens such evidence. The study analyses the monthly rainfall, runoff and runoff coefficient series using the nonlinear prediction met
In recent years, significant effort has been devoted to develop nanotechnology for drug delivery since it offers a suitable means of delivering small molecular weight drugs, as well as macromolecules such as proteins, peptides or genes by either localized or targeted delivery to the tissue of interest. Nanotechnology focuses on formulating therapeutic agents in biocompatible nanocomposites such as
Control systems are ubiquitous and often at the core of Cyber-Physical Systems, like cars and aeroplanes. They are implemented as embedded software, that interacts in closed loop with the physical world through sensors and actuators. As a consequence, the software cannot just be tested in isolation. To close the loop in a testing environment and root causing failure generated by different parts of
Prostate-specific antigen (PSA) is a serine protease secreted by hath normal prostate glandular celts and prostate cancer cells. The major proteolytic substrates for PSA are the gel-forming proteins in semen, semenogelin (Sg) I and II. On the basis of the PSA cleavage map for Sg I and II, a series of small peptides (ie., ≤ 7 amino acids) was synthesized and coupled at the COOH terminus to 7-amino-
Reliable quantitative vegetation reconstructions for Europe during the Holocene are crucial to improving our understanding of landscape dynamics, making it possible to assess the past effects of environmental variables and land-use change on ecosystems and biodiversity, and mitigating their effects in the future. We present here the most spatially extensive and temporally continuous pollen-based r
The diagnosis of lymphoma relies mainly on clinical examination and laboratory explorations. Among the latter, morphological and immunohistochemical analysis of a tissue biopsy are the cornerstones for proper identification and classification of the disease. In lymphoma with blood and/or bone marrow involvement, multiparameter flow cytometry is useful. This technique can also be applied to fresh c
Queer/ed children and young people inhabit a space that seems nicely delineated by shamed biographies, fearful prospects and ignorance. In mainstream accounts, queer/ed children and young people are often un/represented through invisibility or drama, between exoticism and pity. ‘Children’ and notions of ‘the best interest of the child’ are used to dramatize and limit societal negotiations of sexua
MAX IV is a synchrotron facility currently running 14 beamlines hosting about 1000 users per year. It is one of the best of its kind; producing high quality Xrays at the forefront of synchrotron science. To have a beamline or a synchrotron functional, every equipment used needs to be placed in the workspace with high precision. In the current setup, this is supported by bluelining, a technique to
Barnagaförbudet i svensk rätt innebär ett absolut skydd för barn att leva ett liv fritt från övergrepp. Förbudet präglas av principen om barnets bästa. Barnagaförbudet innebär däremot inte att alla typer av övergrepp mot barn är sanktionerade med straff. En grupp som riskerar att falla utanför svensk straffbestämmelse är de barn som utsätts för våld i hemmet utan att det lämnar synliga spår. BrottThe Swedish law against child violence implies an absolute prevention for children against abuse. The best interest of the child is paramount in the law. However, all forms of violence against children are not subject to criminal liability. This includes children that are subject to domestic violence in other forms than physical abuse. The offense of abuse against a child according to Swedish law,
Intresset för probiotika har vuxit de senaste åren. Förutom att vara ha en förebyggande effekt och vara en effektiv behandling mot akut diarré, finns det forskning som indikerar att probiotika kanske kan användas för att förebygga andra sjukdomar, t.ex. tjocktarmscancer. Utmaningen med probiotika är att för att den ska ha någon effekt, krävs det att tillräckligt många levande bakterier når tjocktaThe interest in probiotics has grown in the last few years. In addition to being effective in treating and preventing acute diarrhea, there are indications that it might be possible to use probiotics to prevent other diseases such as colon cancer. The challenge with probiotics is that for it to have any effect, enough viable bacteria must reach the colon. To deliver live probiotics to the colon, i
