Endoscopic sinus surgery (ESS) is today a common method for the treatment of chronic rhinosinusitis. Assessment of the results has been based mainly upon subjective evaluation, and only a few reports present objective measurements, In the present study, the 133-xenon washout technique was used for preoperative and postoperative evaluation of paranasal sinus ventilation in 12 patients selected for

As home care increases and care is moving from nursing homes and hospitals into people’s homes, there are problem areas that need to be addressed and solved in a better way than today. Nurses and other home care workers are exposed to serval risks when the patients’ home environment becomes their workplace. There are also serval risks for the patients when their homes are transferred into “small h

Glucagon was discovered in 1922 as a hyperglycemic factor in the pancreas. During its early history up to 1970, glucagon was shown to increase circulating glucose through stimulating glycogenolysis in the liver. It was also shown to be a constituent of islet non-ß cells and to signal through G protein coupled receptors and cyclic AMP. Furthermore, its chemical characteristics, including amino acid

L-DOPA-induced dyskinesia is a major problem in the treatment of Parkinson's disease. Today there are few anti-dyskinetic treatments available for the patients, and all of them have major limitations. Recent findings have revealed an important role of the serotonin system in L-DOPA-induced dyskinesia. In the parkinsonian brain, serotonin axon terminals can compensate for the dopamine loss by conve

Interstitial lung disease (ILD) encompasses a heterogeneous group of more than 200 con-ditions, of which primarily idiopathic pulmonary fibrosis (IPF), idiopathic nonspecific interstitial pneumonia, hypersensitivity pneumonitis, ILD associated with autoimmune diseases and sarcoidosis may present a progressive fibrosing (PF) phenotype. Despite different aetiology and histopathological patterns, the

The digital cellular systems era started about thirty years ago with the release of the first digital cellphones. These first digital cellphones were very different from today’s slim and esthetic cellular pocket computers. They were not mass-produced in million units a day, and they were designed for radio performance rather than appearance. Today, all components are integrated inside the mobile p

Abstract In Sweden many older closed municipal landfills lack current safety measures such as bottom liners and contain hazardous materials that are today strictly regulated or banned. Emissions from these pose a threat to health and environment now and in the future, having the potential to contaminate soil, groundwater, surface water and air. Risk for exposure is often increased due to poor doc

This essay describes the human relationship to the Swedish Agricultural open landscape, which is romanticised in popular culture, but is also seen by the anthropocentric hegemony in society as a landscape to use as resource for consumption and as symbol for “nature products”. The research deals whit the dualistic approach to cultural landscape by using a semiotic analyse of two food company brands

Utveckling av mätteknik för mätning av rörligheten i knäleder hos barn med Cerebral pares Cerebral pares (CP) är en neurologisk störning som kan leda till förlust eller nedsättning av de motoriska funktioner som påverkar kroppens rörelser, muskelkontroll, koordination och balans. CP kan orsaka obalanser mellan musklerna som kan leda till kontrakturer. Kontrakturer innebär att musklerna förkortas Cerebral Palsy, commonly referred to as CP, is a neurological disorder that results in loss or impairment of motor function, which affects body movement, muscle control, muscle coordination and balance. In Sweden, about 200 children are diagnosed with Cerebral Palsy every year and the disorder can cause imbalances between the muscles. These imbalances can lead to contractures which is equiva- lent

PURPOSE: We developed a new family of test algorithms. This is an evaluation in normal subjects. METHODS: One eye in each of twenty normal subjects, with a mean age of 37 years (range 26 to 59), was tested twice with each of the SITA, Full Threshold and Fastpac strategies of the Humphrey perimeter at 3 separate visits. Actual test times and number of stimulus exposures were compared. Test-retest

This book is intended as an introduction to the breadth of current research in cognitive science, with the research at Lund University Cognitive Science as our sample. The result is a smorgasbord for readers with some background in the neighbouring disciplines. Through the chapters we will follow some of the important cross-disciplinary issues in cognitive science. One is how the external world

Popular Abstract in Swedish Trådlösa system som använder elektromagnetisk strålning, även kallat radio kort och gott, har fått ett enormt genomslag i våra liv. Radio används överallt: telefoni, GPS, mobilt bredband och TV är tillämpningar som vi som privatpersoner lätt kommer i kontakt med men även till radar, magnetisk resonanstomografi och andra avbildande system. Speciellt datakommunikation i mThis thesis investigates the opportunity of wireless multi-gigabit per second communication at the millimeter-wave (mmW) frequencies around 60 GHz by using impulse radio and nanoelectronics. Today most wireless communication take place in the microwave region, where several different systems and applications are crowding the narrow-band channels. Complicated schemes are applied in order to avoid i

Riskbaserad monitorering – ett sätt att säkerställa kvalitet i kliniska studier Kliniska studier undersöker effekter av medicinska behandlingar på människor. De är hårt reglerade för att säkerställa patientsäkerhet, det vill säga att försökspersonerna inte utsätts för onödiga hälsorisker, och för att säkerställa ett pålitligt studieresultat. Därför behöver alla processer och all data i varje studStudy quality is of paramount importance in clinical studies to ensure patient safety and reliable evaluation of the treatment, where the latter also entails the safety of future patients. Therefore, for example monitoring is required to minimise any risk of quality loss. Traditionally, the method for monitoring has been 100% source data verification which is costly and not sufficient. Today, auth

The most common way to develop System-on-Chip's (SoC) today is to utilize hardware design on a Field programmable gate array (FPGA). By utilizing the hardware on an FPGA, the opportunity to verify the hardware and start software design before implementing the final solution on silicon is possible. However, using an FPGA as a reference model for a final design gives a slightly imprecise estimat

Dagens textilindustri är starkt präglad av fast fashion, en global industri som bygger på stora inköp och små marginaler vilket leder till en överproduktion där 40 procent av de textilier som tillverkas globalt aldrig kommer ut på marknaden. Detta resulterar i bristande arbets- och levnadsförhållanden i produktionsländer samt enorma utsläpp. Med hjälp av politiska incitament och teknologiska framsToday's textile industry is strongly characterized by fast fashion, a global industry based on large purchases and small margins, leading to overproduction where 4 percent of the textiles produced globally never reach the market. This results in poor working and living conditions in producing countries and huge emissions. With policy incentives and technological advances, we can move towards l

Detta examensarbete undersöker möjligheten att förbättra produktnivåmätningen i en av Tetra Paks fyllnadsmaskiner, eftersom den nuvarande lösningen inte detekterar den med den önskvärda precisionen, samt mätområde. Idag används en magnetisk flottör tillsammans med 16 separata kapacitiva sensorer. Problemet med detta är att förpackningar blir avvisade på grund av en felaktig mängd produkt. Detta skThis thesis examines the possibility to improve the product level sensing in one of Tetra Pak’s filling machines, because the current solution does not detect this with the desirable precision, as well as measuring range. Today, a magnetic float is used together with 16 separate capacitive sensors. The issue with this is that packages get rejected due to a faulty amount of product. This occurs bec

I dagens samhälle blir befolkningen äldre och kraven på äldrevården ökar. Snabbare, mindre avslappnade och ovärdiga tvättmetoder används i större utsträckning såsom exempelvis duschning eller tvätt i sängen. Arjo strävar efter att öka badandet inom äldrevården och att inkludera en känsla av välbefinnande och avslappning, samt att badproceduren ska upplevas med värdighet hos vårdtagarna. Detta för Today, the population is getting older and the demand on long-term care facilities is increasing. Faster, less relaxing and undignified washing methods are more prone to be used, such as showering or in bed washing. Arjo strives to increase bathing and to include a feeling of wellness, making bathing a dignified and relaxing experience. This, in order to increase the quality of life for people fac

The relationship between Church of Sweden’s diocese of Lund and the Evangelical Church of the Church Province of Saxony in the German Democratic Republic started in 1983 and came to an end with the fall of the Berlin wall in 1989. The exchange-based relationship between the two churches started with a request from the church in East Germany, searching for allies and ecumenical contacts in Western

Relationship marketing is getting more focus from researchers today. The idea of earning the trust and loyalty of customers by engaging in relationships has been put to practice in many retail areas. Retailers and researchers are stressing the importance of establishing relationships with their customers and are in many ways focused on the physical service encounter. Literature often suggests that
