Populärvetenskaplig sammanfattning Ska du flyga långt med de där vingarna? Vissa fåglar flyger långt, andra inte. Silvertärnorna flaxar med vingarna från Arktis till Antarktis medan pingvinerna använder vingarna för att simma och inte flyger alls. Eftersom att olika fåglar använder sina vingar på så olika sätt så har nämnda vingar anpassats efter vingbärarnas behov. Vissa studier har visat sambaAbstract Bird wings are adapted to the needs of the birds and bird wings therefore differ between species, but also between ages and sexes. In this thesis, an interspecific analysis investigating relations between measurements of wing shape for birds within the Sylviidae-family, revealed strong connections between morphologically unrelated measurements. Long distances (compared to the wing length

I Sverige överenskommes årligen tusentals uppdrag som kan hänföras till området för entreprenader. Entreprenaduppdrag kan vara alltifrån mindre åtaganden till omfattande arbeten med höga kontraktsbelopp. Eftersom dessa arbeten faller utanför KöpL tillämpningsområde uppkommer ett behov av reglering vilket görs inom ramen för den så kallade entreprenadrätten. Entreprenadrätten har i brist på lagreglYearly, thousands of transactions in Sweden can be related to construction of some kind. These constructions can be very various in scope, everything from small undertakings, to extensive long term assignments. Since general purchasing laws of Sweden are not applicable for constructions, there is a need for regulation concerning these assignments. Consequently, a standard agreement – ‘Allmänna Bes

This report evaluates and compares the methods in fire inspection at Malmø Fire Brigade and Copenhagen Fire Brigade. The report also examines fire safety laws and regulations and the educational differences of the fire inspectors in Malmø and Copenhagen. The investigation is a project for Malmø Fire Brigade and Copenhagen Fire Brigade in co-operation with the Department of Fire Safety Engineering

In this study, the transmission and reflection of two conductive fabrics are investigated in the frequency range from 2 to 18 GHz. One of the fabrics is a non-woven polypyrrole and the other consists of a polyethylene warp with steel threads in the weft. Reflection and transmission measurements are performed in order to characterize the electromagnetic properties of the materials. Reflection measu

BACKGROUND: Cost-effective fermentation of lignocellulosic hydrolysate to ethanol by Saccharomyces cerevisiae requires efficient mixed sugar utilization. Notably, the rate and yield of xylose and arabinose co-fermentation to ethanol must be enhanced. RESULTS: Evolutionary engineering was used to improve the simultaneous conversion of xylose and arabinose to ethanol in a recombinant industrial Sacc

Bakgrund: Den kurativa behandlingen för resektabla lokalt avancerade stadier av cancer i munhålan innefattar i regel en kombination av kirurgi och radioterapi (RT). Huruvida RT bör ges först och därefter följas av kirurgi, eller om tumören bör opereras bort först, följt av RT postoperativt, har dock inte studerats i någon större omfattning.Syfte: Denna avhandling undersöker olika aspekter av pre- Background: The curatively intended treatment for resectable locally advanced stages of oral cavity cancer (OCC) generally involves a combination of surgery and radiotherapy (RT). However, whether to apply RT first and then proceed with surgery, or to resect the cancer and subsequently administer RT, has not been extensively studied. Aims: This thesis examines various aspects of pre- versus postop

Effekter av träning i fastande tillstånd Den tydligaste effekten av uthållighetsträning är förbättrad kondition. Ordet kondition kan definieras som samspelet mellan lungor, hjärta, blod och muskler. Lungorna ska växla syrgas från inandningsluften och släppa ut koldioxid. Hjärtat ska pumpa blod till lungorna och ut i kroppen. Blodets uppgift är att syresätta musklerna vid fysisk ansträngning. Allt

I juni 2011 antog ILO konventionen om goda villkor för hushållsarbetare. Konventionen fastställer anställningsvillkor och arbetsrättigheter för hushållsarbetare. Hushållsarbete sker, till skillnad från andra former av arbete, i privata hem utan insyn från det offentliga och är ofta ett ensamarbete. Detta innebär att hushållsarbetare riskerar att bli utsatta för missförhållanden och exploatering. KIn June 2011, the Domestic Workers Convention was adopted in the ILO. The Convention establishes minimum conditions of employment and labour rights for domestic workers. In contrast to other types of work, domestic work takes place in private households, in isolation and hidden from public insight. This makes domestic workers vulnerable to abuse and exploitation. The Domestic Workers Convention ob

Grand challenges such as climate change put focus away from innovations and innovation policy as engines of economic growth towards fulfilling societal goals and sighting sustainable development. The literature on the geography of innovation has provided valuable insights on innovation activities of firms and industries and how they are positively influenced by co-location. In particular, short ge

BackgroundPeople with intellectual disability have been found to have higher prevalence of psychiatric disorders than the general population. However, they do not seem to have a corresponding increase in psychiatric care utilization. The aim of the present study was to investigate psychiatric care utilization among older people with intellectual disability.MethodsWe used a cohort of people with in

To reduce greenhouse gas (GHG) emissions and help mitigate climate change, urban water systems need to be adapted so that electrical energy use is minimised. In this study, energy data from 2011 was used to quantify energy use in China’s urban water supply sector. The objective was to calculate the energy co-benefits of urban water conservation policies and compare energy use between China and oth

BackgroundNursing home residents in Sweden are old, frail and usually have multiple morbidities which often make dying a prolonged suffering. It has been found that older persons at nursing homes receive far less palliative care than younger persons, partly because it is difficult to identify when the final stage of life begins. The identification may help the staff to enable the older person and

The demand for gas turbines suitable for Low Btu gases is increasing worldwide. This paper presents a theoretical and experimental investigation of the flammability limits of Low Btu gases for gas turbine applications. Most modern gas turbines utilize premixed combustion, making it important to know at which fuel-air ratio the flame extinguishes. The flammability limit for a gaseous fuel is a prop

The two-photon absorption (TPA) properties of β-carotene (beta-carotene) in chloroform solution were investigated over the 590-790 nm wavelength range. The TPA was characterized using the open-aperture z-scan technique with picosecond pulses provided by a widely traveling-wave optical parametric amplifier (OPA) pumped with a Ti:sapphire laser amplifier. We found the 0.2-1 cm/GW values of two photo

The contribution of the understorey vegetation to the spectral reflectance from the top of a forest canopy was investigated by the use of a forest canopy reflectance model. Detailed field data, i.e. forest leaf area index (LAI), tree structural parameters like the height, diameter and crown length of the trees, and the composition, distribution and reflectance of the forest floor, was collected fo

Background: Home care service (HCS) for sick children is a complex healthcare service, which can be organised in various models. Despite the possibility to support family everyday life, the accessibility and utilisation may still be limited. The aim of this study was to (i) determine characteristics in referrals to county-based HCS, (ii) determine characteristics of referred children and (iii) ass
