A novel method for detection of reducing ends of sugars is proposed, based on the use of Fe(CN)(6)(3-) as the oxidant in combination with amperometric detection and flow injection analysis (FIA). The method is very sensitive, giving values of < 10 mu M for the limit of detection for a series of mono- and oligosaccharides. Samples can be analysed every 30 s, and injection can be made fully automate
The demands on wireless communications are continuously growing, due to the fact that when higher network capabilities are delivered, new features and applications are created, calling for even higher requirements. To keep pace with these demands and to allow new applications to rise, the limits of mobile networks must be pushed regularly. Therefore, the International Telecommunication Union targe
Inside the Swedish National Board of Institutional Care (SNBIC) are juveniles who are receiving treatment from pedagogues and assistants that are frequently threatening their caregivers. The threats consist of physical and verbal behavior. This type of working environment can be very bad for one's well being. The study focuses on investigating how the staff's well-being is affected by work
By applying one of the largest datasets on ESG ratings to date with around 8000 companies included during the sample period between 2006-2021. This paper investigates the increasingly popular link between firms’ social and financial performance and the potential abnormal returns to be found using ESG investment strategies. To examine this relationship, a series of portfolios are constructed based
The late eighteenth and the early nineteenth century was a turbulent time for the monarchies of Europe, the Swedish included. Since Gustav III’s coup in 1772, the king strove to enhance the royal prerogative. Ceremonies were crucial in the monarchy’s language of power and establishment of legitimacy but oppositional forces within the nobility nevertheless provoked the regicide of Gustav III in 179
There is not much research done regarding maneouvering flight on Birds. What has been done surrounding the area usually involves steady flight and not maneuvering. For the most part studies concern bats, insects or hummingbirds. What makes research on maneuvering on birds important is that in a bird’s everyday life, very little of it consists of steady flight. This study has looked on the Pied fly
Utbildning är en viktig del av vårt samhälle och med hjälp av ny teknik finns det utrymme för förbättring. Idag används datorer, applikationer till smarta telefoner samt surfplattor i stor utsträckning inom utbildning. En ny teknikrevolution håller på att äga rum, nämligen Virtual Reality. Detta examensarbete undersöker användbarheten för Virtual Reality som utbildningsverktyg. Eftersom Virtual ReEducation is an important part of our society and with technological advancements there is room for imporvement. Computers, smartphones, tablets and applications are widely spread as educational tools in todays classrooms. A new technological revolution is about to happen, which is called Virtual Reality. This thesis examines the usability of Virtual Reality as an educational tool. Since Virtual R
Flexible Polyvinyl chloride (PVC) is a plastic material commonly used in today’s society and a fundamental material for a lot of sectors. It has advantages over other polymers such as energy-efficient production, flame retardancy, durability and cost-effective. The one important component in flexible PVC that gives it is flexible properties is the plasticizer. The most common plasticizers used are
The interactions of lipid based cubic liquid crystalline nanoparticles (Cubosome (R)) with surface supported model membranes constituted of dioleylphosphatidylcholine ( DOPC) have been studied in situ by use of ellipsometry, quartz crystal microbalance with dissipation monitoring and neutron reflectivity. The systems investigated were cubic phase dispersions of glycerol monooleate (GMO) stabilised
The purpose with our essay was to examine which risk- and protective factors that exist for children of alcoholics. We wanted to increase our understanding and knowledge about the situation of these children. It is a literary study, which covers the most frequently quoted results in the field of research. The questions for our study were; which risk factors can one as a parent with alcoholic abuse
År 2025 fick en särskild utredare i uppdrag att analysera hur barnets ställning och stödet till barn i vårdnadsmål kan stärkas. Genom uppsatsens undersökning och analys av den historiska utvecklingen av barns delaktighet i vårdnadstvister under de senaste 100 åren framkommer att det är långt ifrån första gången som denna fråga utreds. Frågan har nämligen utretts ett flertal gånger i statliga offenIn 2025, a special investigator was commissioned to analyze how the position of the child and the support for children in custody cases can be strengthened. Through the thesis’s investigation and analysis of the historical development of children´s participation in custody disputes over the past 100 years, it emerges that this is far from the first time this question has been examined. The issue h
One of the major challenges in forensic genetics is being able to detect very small amounts of DNA. Massively parallel sequencing (MPS) enables sensitive detection; however, genotype errors may exist and could interfere with the interpretation. Common errors in MPS-based analysis are often induced during PCR or sequencing. Unique molecular indices (UMIs) are short random nucleotide sequences ligat
The life expectancy of people with intellectual disabilities (ID) has steadily increased, which has been accompanied by an increased risk of dementia. Staff and managers are key resources for safety diagnosis since they deliver information about people with ID behavior every day. The aim of the present study was to explore the identification process employed by staff and managers to detect signs o
The consumption of legume seeds in developing countries is very important because of their low cost and valuable nutritional characteristics (high protein, digestible and indigestible carbohydrates, and polyphenols content). However, limited information is available on the indigestible carbohydrates and the antioxidant capacity of legumes growing in Mexico. The cooked seeds of three Mexican pulses
Tests were done measuring resistivity and time domain induced polarisation using standard multi-core cable spreads and a special layout with separate cable spreads for transmitting current and measuring potentials. For both types of cables spreads both normal and reciprocal measurements were done in order to estimate the measurement errors. The tests were done on a former landfill in Lund in Swede
Background and aim: Family caregivers are often involved in helping recipients during allogeneic hematopoietic stem cell transplantation (allo-HSCT). Although the distress that often arises along the trajectory is evident to family caregivers, research on their perceptions of providing and receiving support is limited. The aim of this study was to explore family caregivers’ experiences of providin
A wind-borne plume of sex pheromone from a female moth or a synthetic source has a fine, filamentous structure that creates steep and rapid fluctuations in concentration from a male moth flying up the plume's axis. The firing rates from single antennal neurons on Agrotis segetum antennae decreased to nearly zero within seconds after the antennae were placed in a pheromone plume 70 cm downwind of a
Wrought Alloy 600 and Alloy 182 weld metal were tested for stress corrosion crack initiation in a BWR test loop. For the tests a modified bolt loaded compact tension specimen was developed, in which a U-notch replaced the conventional crack notch. The stress state close to notches of various radii was analyzed. Specimens with various notch radii were loaded to the same displacement at the bolt. A
Ants are abundant in natural and managed tropical ecosystems and can have an impact on herbivorous arthropods, as well as plant pathogens. Although it has been shown for plants that the diversity of communities can result in improved ecosystem functioning, it remains uncertain how the species richness of ants affects multiple ecosystem services and disservices. In the present study, we used experi
