A compilation of the applied experimental conditions when studying metal ion adsorption onto kraft fibres, and the resulting conclusion, revealed that the ionic strength conditions used during the experiments were an important dividing factor. At low ionic strengths, the conclusion has regularly been that the Donnan ion-exchange model could correctly predict the adsorption while, at higher ionic s
The cell is the fundamental unit of life and in multicellular animals, all cells are derived from stem cells. To understand how stem cell development may influence phenotypic evolution, this thesis studies a population of vertebrate stem cells known as neural crest cells (NCCs). With unparalleled potency and migratory behavior, NCCs affect many different traits spread over the entire vertebrate boThe cell is the fundamental unit of life and in multicellular animals, all cells are derived from stem cells.

Background: Emerging evidence suggests that anterior cruciate ligament (ACL) ruptures can restore ACL fiber continuity. The relationship between ACL continuity on magnetic resonance imaging (MRI) (sign of ACL healing) and outcomes >5 years after an acute ACL rupture has not been investigated. Purpose: This study aimed to (1) describe clinical outcomes and radiographic osteoarthritis (ROA) at 11 ye
Land use/vegetation cover change, reflecting a range of human land use practices, is the most prevalent and immediate influence on alterations in soil quality. The physical structure of soil is crucial for safeguarding soil carbon (C) and nitrogen (N), as it modulates the physical protection mechanisms and the distribution of these elements within the soil. Nevertheless, the impact of soil physica
Background Monitoring labor and childbirth, early recognition, and treatment of complications are critical for preventing adverse birth outcomes. However excessive use of interventions during labor has not been demonstrated to enhance subsequent birth outcomes and may, in fact, pose a risk of harm. The World Health Organization has recently synthesized research from the last decade concerning labo
BACKGROUND: Stereotypes may prevail, but little is known about the influence that the sex of an orthopaedic surgeon may have on outcomes. In a recently published study, there were no differences in the rate of adverse events following total hip arthroplasties (THAs) performed by female or male orthopaedic surgeons. The objective of the present study was to investigate whether there was any differe
Classroom-based language learning has typically taken place in relatively static body positions, but research suggests that embodied learning through sensorimotor engagement and technical immersion, using virtual realities, can significantly enhance learning outcomes. Recent research has linked differences in the learning context to different cortical structures within the language learning networ
Datakommunikation och nätverk ger en heltäckande och lättillgänglig redogörelse av modern datakommunikation. Boken är ett alternativ till internationella textböcker i ämnet, innehållet speglar kunskapsbehovet hos yrkesverksamma ingenjörer och ger de kunskaper som krävs på ett pedagogiskt och kärnfullt sätt. Boken innehåller förutom övningar även lästips och hänvisningar för den som vill söka fördj
A recent study carried out by our group demonstrated that exogenous dopamine increases the somatostatin (SS) receptor–effector system in the rat striatum. The present study examined the participation of the D1- and D2-dopaminergic systems in the modulation of the rat striatal SS receptor–effector system by use of the D1-receptor agonist and antagonist SKF 38393 and SCH 23390, respectively, and the
The aims of this study were to determine and evaluate simultaneously the importance of factors known to influence sick-leave certification such as the sick leave-related diagnoses, the patients' socio-economic status, and characteristics of the physicians.
The third meeting of the International Society for Holter and Noninvasive Electrocardiology working group was convened in Lund, Sweden, in June 2010 to consider the key clinical challenge of developing electrocardiographic (ECG) criteria for identification of the global subendocardial ischemia that results from subtotal occlusion of either the left main coronary artery or its equivalent. The parti
Ovariectomized virginal rabbits were treated with either estrogen or progesterone for 4 to 6 months. In vitro responses of muscle strips of the bladder and circular urethra were examined. Estrogen resulted in bladder contractions in response to noradrenaline and phenylephrine, whereas these agonists were without effect or evoked weak relaxations in castrated animals (and normals). Estrogen also ca
Professionals who take part in the building process have long been concerned with the same environmental factors, e.g. spatial layout, capacity, and function, as well as user demography. Through the knowledge gained on the ways environmental factors affect users of buildings, the need to understand how to handle these factors has grown, due to their influence on the building process. It will be sh
This study investigated the role of P fimbriae in colonization of Escherichia coli, host response, and bacterial persistence in humans. Human volunteers were inoculated intravesically with the nonadherent ABU isolate E. coli 83972 and with P fimbriated transformants of the same strain. During the following 24 h all urine samples, and thereafter daily samples, were collected for urine culture, anal
Caesiated InAs(111)B (1 x 1) and InAs(111)A (2 x 2) surfaces have been studied by photoelectron spectroscopy. On the InAs(111)B a new (root 3 x root 3)R30 degrees reconstruction was observed. During Cs evaporation remarkably small changes are observed in the lone pair states, and no sign of an accumulation layer at the surface can be observed. Instead, the additional charge provided by Cs is rapid
In adipocytes, PDE3B (phosphodiesterase 3B) is an important regulatory effector in signalling pathways controlled by insulin and cAMP-increasing hormones. Stimulation of 3T3-L1 adipocytes with insulin or the beta(3)-adrenergic receptor agonist CL316243 (termed CL) indicated that insulin preferentially phosphorylated/activated PDE3B associated with internal membranes (endoplasmic reticulum/Golgi),
Partially due to years of poor water management practices in Moldova, water resources are increasingly becoming a concern. This situation is intensified by the pollution of water bodies that could be used for drinking water supply. An improvement of the water supply system in Moldova’s capital city Chisinau would result in an upgrading of water quality and hence increased health and living conditi
Abstract Deforestation and the use of fire to clear land have drastic effects on ecosystem functioning and compromise the continuity of many important ecosystem services. This is specially the case in tropical countries such as Madagascar, where people's reliance on forest exploitation and subsidence agriculture is driving severe forest decline. In this study we evaluated the effects of slash
Landskrona appears in many contexts as a city with constant social problems and violent crime. These are mainly linked to the central areas. Although, if you look at statistics of violent crime of Landskrona the numbers have actually decreased in recent years. Therefore the thesis of this paper is about violent crime in the city of Landskrona. My approach has been applying two different theories o
