During the past century, Lake Takern and Lake Krankesjon, southern Sweden, have shifted repeatedly between a state of clear water and abundant submerged vegetation, and a state of turbid water and sparse vegetation. Long-term empirical data on such apparently alternative stable state dynamics are valuable as complements to modeling and experiments, although the causal mechanisms behind shifts are
Absolute regional cerebral blood flow (CBF) was measured in ten healthy volunteers, using both dynamic susceptibility-contrast (DSC) magnetic resonance imaging (MRI) and Xe-133 SPECT within 4 h. After i.v. injection of Gd-DTPA-BMA (0.3 mmol/kg b.w.), the bolus was monitored with a Simultaneous Dual FLASH pulse sequence (1.5 s/image), providing one slice through brain tissue and a second slice thro
Wide-band intermediate-frequency (IF) amplifiers are needed when the data rates of communication systems increase. A single wide-band IF amplifier can also be used for a radio band with several narrow-band channels of varying strengths. High linearity is then required if intermodulation products are not to disturb weak channels. We have previously reported a highly linear wide-band IF amplifier in
Syftet med studien var att undersöka hur personer som tidigare erhållit socialbidrag beskriver orsakerna till att de inte längre behöver socialbidrag samt hur de upplevde kontakten med socialtjänsten. Målgruppen har varit hushåll som idag klarar sin försörjning utan det behovsprövade socialbidraget. Undersökningsgruppen bestod av 158 hushåll i Jönköpings kommun som under 1997 avslutat sin kontakt
This work consists of seven essays, with each concerning a specific subject that is related to architecture. There is additional text, which pertains to this work's examination requirements for graduating the architecture-program at Lund Technical University. This work is a creative explorations through writing as a tool; through text; becoming able to formulate, conceptualize, develop and ext
Air Traffic Controllers (ATCOs) are essential sharp-end workers in the increasingly complex Air Traffic Management (ATM) system that the European ATM network has become. This research is based on an event that occurs many times daily in the Copenhagen Area Control Center (ACC). ATCOs choose whether or not to split sectors. To cope with workload, which is constituted by variation in traffic volume
Inverse problems are important in quantum physics as their solutions are essential in order to describe a number of systems using measurable information, e.g. excitation energies or material properties. The problem with inverse problems is that they are usually very hard to solve. One method that could be useful in solving these problems is artificial neural networks. Artificial neural networks ha

Vomb meadows is an area well knows for its rich bird life. During the 19:th century until mid 20:th century, the meadows were flooded annually in order to increase the hay yield. The river Klingavälsån situated along the west side of the meadows, used to be a shallow river, meandering across the landscape. In the 1940’s the river was straightened and made deeper. This was done in purpose of draini
The expression treaty shopping is of American origin and it is closely related to the term forum shopping, a term used in U.S. civil procedure. Forum shopping describes a behaviour by which a party in a court case tries to ''shop'' into a jurisdiction or circuit where he expects a more favourable decision to be given. When treaty shopping, one uses double taxation treaties (and/or
This thesis examines and analyses the relationship between the principle of complementarity and the principle of universal jurisdiction. The establishment of the International Criminal Court provides for the first time in history a permanent international criminal institution. One of the most important principles on which the ICC is built upon is the principle of complementarity. The road towards
The increase of the consumer electronics market the last couple of decades has been one of the main drivers of IC process technology development. The majority of the ICs are used in digital applications, and for these CMOS is the choice of technology. The urge to squeeze more transistors on to a given area has led to shrinking feature sizes. It has resulted in higher transition frequencies and red
Dimethyl sulfoxide (DMSO) is a highly utilized small molecule that serves many purposes in scientific research. DMSO offers unique polar, aprotic and amphiphilic features, which makes it an ideal solvent for a wide variety of both polar and nonpolar molecules. Furthermore, DMSO is often used as a cryoprotectant in cell-based research. However, recent reports suggest that DMSO, even at low concentr
Background: Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anoma
In vehicular communications systems the channel estimation filter suppresses the additive noise in channel estimates obtained from pilot symbols. Vehicular channels show local stationarity for a finite region in time and frequency, only. Such a process can be divided into consecutive stationarity regions, allowing to calculate a Wiener filter. We analyze the increase of the mean square error (MSE)
Dolphin sonar has been extensively studied over several decades, and much of its basic characteristics are well known (Au 1993). However, most of these studies have been based on an experimental setup where the dolphin has been trained to be voluntarily fixed, so its directional sonar beam could be recorded with fixed hydrophones. Although this allows for very exact measurements, it most likely ha
Purpose: Objective diagnosis of symptomatic urinary tract infections in patients prone to asymptomatic bacteriuria is compromised by local host responses that are already present and the positive urine culture. We investigated interleukin-6 as a biomarker for nonfebrile urinary tract infection severity and diagnostic thresholds for interleukin-6 and 8, and neutrophils to differentiate between asym
Estrogen receptor (ER) positive tumors represent the majority of breast malignancies, and are effectively treated with hormonal therapies, such as tamoxifen. However, in the recurrent disease resistance to tamoxifen therapy is common and a major cause of death. In recent years, in-depth proteome analyses have enabled identification of clinically useful biomarkers, particularly, when heterogeneity
OBJECTIVES: To illuminate patterns observed in International Cancer Benchmarking Programme studies by extending understanding of the various influences on presentation and referral with cancer symptoms.DESIGN: Cross-country comparison of Denmark, England and Sweden with qualitative analysis of in-depth interview accounts of the prediagnostic process in lung or bowel cancer.PARTICIPANTS: 155 women
To remain competitive in the field of manufacturing today, companies must make their industrial robots smarter and allow them to collaborate with one another in a more effective manner. This is typically done by adding some form of learning, or artificial intelligence (AI), to the robots. These learning algorithms are often packaged as cloud functions in a remote computational center since the a
