Popular Abstract in Swedish Hårdvara och algoritmer för ett inbyggt videoövervakningssystem presenteras i denna avhandling. För att verifiera systemet så har en prototyp byggts.The demands on video surveillance systems are rapidly increasing regarding parameters such as frame rate and resolution. Furthermore, with an ever increasing number of video streams, an automated process for extracting relevant information is required. Due to the large amount of input data and the computational complexity of the algorithms, software implementations are not sufficient to sustain re

The influence of temperature, salts, pH, and various pre-treatments and cleaning on the nanofiltration (NF) performance of thin-film polyamide (PA) composite membranes has been investigated. The change in membrane performance was correlated to membrane swelling or/and electroviscous friction. Aspects of costs and energy demand while using NF at elevated temperatures were also evaluated. The increa

The use of enzymes in nonaqueous media has considerably expanded their potential areas of application. Limitations however arise that are inherent to the low conformational flexibility of enzymes in dry organic media. Enzyme activity is often unfavorably low due to kinetic barriers. Enzyme behavior, with respect to heat and long-term inactivation, may deviate from their behavior in aqueous media.

The emittances of the electron beams at the MAX-laboratory accelerator system have been studied. Apart from the build-up of the diagnostic tools for precise determination of the beam spatial profiles, the objectives have been: a) to verify the accelerator design emittances at low currents and to try to determine the emittances also at high currents; b) to investigate possibilities to manipulate th

Popular Abstract in Swedish Elektrocochleografi (ECoG) är en metod som mäter de elektriska signaler som uppstår i innerörat när örat stimuleras med ljud. Signalerna uppstår i snäckans sinnesceller, de så kallade hårcellerna, och i nervcellerna som utgår från snäckan. Snäckan är det organ som omvandlar ljudets mekaniska energi till elektriska signaler i hörselnerven. Hörselnerven förmedlar signalerElectrocochleography (ECoG) is an objective method to evaluate cochlear electrophysiology. The recordings are considered to reflect the mechano-electric processes of the cochlea, and can indicate the presence of suspected endolymphatic hydrops. The aim of the present thesis was to investigate the value of transtympanic (TT) ECoG in the clinical diagnosis and management of Menière´s disease. The tr

Popular Abstract in Swedish Denna avhandling behandlar modellsystem för farmaka som har DNA och RNA som mål i cellen. Framförallt behandlar den hur strukturen hos DNA och RNA påverkas av inbindning av olika substanser, samt hur fort denna inbindning sker. Tre olika typer av farmaka behandlas: 1. Platinaföreningar som länge använts som cytostatika, 2. RNA interferens som främst har utvecklats undDrugs targeting nucleic acids were studied in DNA and RNA model systems. The effects were investigated with respect to structural and thermodynamic influence, kinetics, and biological function. The drugs employed in this thesis were anticancer active platinum(II) complexes, polyamine derivatives, and siRNA. Structural changes were determined by use of chemical probing and circular dichroism (CD),

Popular Abstract in Swedish Vid internationell handel med varor utgår olika skatter och avgifter; dessutom kan varorna vara föremål för import- och exportbegränsningar. Genom frihandelsavtal kan dock bestämmas att vissa varor får importeras och exporteras tullfritt. De bestämmelser som således gäller för olika varor sammanfattas för skilda varuslag i tulltaxan. Varuklassificeringen har därför storIn international commerce, various taxes and charges are levied on commodities; besides, goods may be subject to import and export restrictions. However, free-trade agreements may stipulate that some goods can be imported and exported free of charge. The regulations pertaining to different types of merchandise are reflected in the customs tariff of a state or customs union. The application of many

Popular Abstract in Swedish Alla levande organismer har DNA, och eftersom DNA är livsnödvändigt måste det repareras om det blir skadat. Ultraviolett (UV) strålning från solen är en av de vanligaste orsakerna till att DNA skadas. De flesta skador på DNA som orsakas av UV-strålning utgörs av cyklobutan-pyrimidindimerer (CPD) eller (6-4)-fotoprodukter. Dessa skador består av två intilliggande baser sAll living organisms have DNA and since DNA is essential to life it must be repaired when damaged. UV radiation is one of the major DNA damaging agents, which photosynthetic organisms cannot avoid. The major UV-induced DNA lesions are cyclobutane pyrimidine dimers (CPDs) and (6-4) photoproducts (6-4PPs) and the main repair pathways of theses lesions involve photolyases and various excision repair

ACCESSIBLE SUMMARY: • This paper describes Swedish outpatients' perception of the quality of psychiatric care they received. A large number of patients (1340) from 15 outpatient clinics participated in the study. • A newly developed and tested questionnaire, the Quality in Psychiatric Care - Out-Patient, was used. • The patients' highest ratings were for Encounter (staff-patient interaction), the

Popular Abstract in Swedish Cytostatika är en grupp läkemedel som är vanligt förekommande inom sjukvården. Cytostatika används framför allt vid behandling av olika cancersjukdomar, men kan också användas för att behandla andra sjukdomar t. ex. reumatiska sjukdomar. Dessa läkemedel kan vara mycket giftiga, cancerframkallande och fosterskadande. Cyklofosfamid (CP) och ifosfamid (IF) är två vanligt aAntineoplastic drugs are commonly used in the medical treatment of cancer and some other diseases. Workplaces e.g. hospital pharmacies and wards where antineoplastic drugs are used are contaminated with these drugs and health care workers are therefore at risk of getting occupationally exposed. Many antineoplastic drugs are classified as carcinogenic and teratogenic to humans. Cyclophosphamide (CP

One problem with the Swedish railways is the low reliability and punctuality. A distinction can be made between major and minor disorders, where minor disorders have a greater impact on overall punctuality because of its large numbers. One way to describe the large disorders are with punctuality dips and punctuality depressions, which are short-term and long-term variations in punctuality. This st

The release of anthropogenic greenhouse gases (GHGs) has substantially increased the global mean surface air temperature. Increases in global mean surface air temperature will lead to warmer and drier conditions, promoting more frequent, long-lasting, intense forest wildfires. The usage of remote sensing (RS) can aid in quantifying forest characteristics and large-scale changes in forest ecosystem

Climate change is the biggest challenge of our time. The climate is changing dramatically because of human activity and the construction and property sector plays a key role in reducing climate emissions and building a sustainable future. Although the development of climate-smart solutions in the construction and real estate sector has come a long way, the spread of green buildings has encountered

The purpose of this study is to determine and define the property-related strategies of listed Swedish property management companies – and how the choice of strategies affects the company's performance on the stock market. Furthermore, the analysis aims t

The aim of this thesis is to investigate how the news media can challenge a social construction when it covers an event related to a taboo. The main question guiding this thesis is how the news media discourses about the ‘tampon tax´ in France can challenge the menstrual taboo. Every society is constituted of taboos which aim at maintaining order and hierarchies. However, these taboos oppress the

Potential use of circulating tumor DNA as a biomarker in children’s cancer Pediatric cancer is the second most common cause of death in children in the developed countries, even though a highly improvement in diagnostic tools and treatment strategies occurred in the last decade. Cancer patients have to endure long treatments with many side effects, with possible multiple surgeries, and radiation.

Sustainable development at the local level is greatly impacted by policymaking. In China’s Jingmai Mountain region, the sustainable development policies are centred mostly around the tea industry, due to the social and environmental dynamics surrounding tea in that region. However, considering the complex interlinkages between the tea industry and local environment and society, the policies concer

As aerosol particles are important for global climate effects, their sources and influence on global aerosol particle concentrations need to be quantified. One of the major aerosol sources in the atmosphere is new particle formation (NPF) of new nanometer sized particles in the atmosphere. The influence on the global aerosol concentration due to NPF events is however not well quantified. The goals

Cell replacement therapy of neurodegenerative disorders aims to substitute the degenerating cells with new functional neurons. Clinical trails with patients suffering from Parkinson’s or Huntington’s disease have generated proof-of-principle results that neural precursors taken from the developing human brain can survive upon grafting to the diseased brain and provide long-lasting symptomatic reli
