Interaction of Nanometric Clay Platelets

The free energy of interaction between two nanometric clay platelets immersed in an electrolyte solution has been calculated using Monte Carlo simulations as well as direct integration of the configurational integral. Each platelet has been modeled as a collection of charged spheres carrying a unit charge-the face of a platelet contains negative charges, and the edge, positive charges. The calcula

The Emergence of Conditional Subordinators in Swedish : A Study in Grammaticalization

This thesis is an empirical and theoretical study of the emergence of five Swedish conditional subordinators: utan, om, hvar, ifall and bara. The first changes occur in the 13th century, and the last in the 18th century. After a theoretical introduction, in which grammaticalization as well as conditionality and conditional structures are critically discussed, five paths of change are identified. T

Relative Frequencies of Blue Stragglers in Galactic Globular Clusters: Constraints for the Formation Mechanisms

We discuss the main properties of the Galactic globular cluster (GC)blue straggler stars (BSSs), as inferred from our new catalog containingnearly 3000 BSSs. The catalog has been extracted from thephotometrically homogeneous V versus (B-V) color-magnitude diagrams(CMDs) of 56 GCs, based on Wide Field Planetary Camera 2 images of theircentral cores. In our analysis, we used consistent relative dist

Receptor association and tyrosine phosphorylation of S6 kinases

Ribosomal protein S6 kinase (S6K) is activated by an array of mitogenic stimuli and is a key player in the regulation of cell growth. The activation process of S6 kinase involves a complex and sequential series of multiple Ser/Thr phosphorylations and is mainly mediated via phosphatidylinositol 3-kinase (PI3K)-3-phosphoinositide-dependent protein kinase-1 (PDK1) and mTor-dependent pathways. Upstre

Configuration Management for Distributed Development in an Integrated Environment

Configuration management (CM) includes synchronizing and supporting developers in their common development and maintenance of a system. In order to utilize personnel regardless of their geographical location, groups of developers are now working all over the world on the development of common systems, a situation called distributed development. From different locations they may need to concurrentl

Medical and surgical strategies for treating urogynecological disorders

Symptoms and signs of the urogenital estrogen deficiency syndrome occur relatively late in a women's life when endogenous estrogen levels are well below those required to stimulate endometrial growth. At age 60 and above symptoms are common and progress with advancing age. The first and most common complaint is vaginal dryness, but symptoms of lost control of micturition as well as urge incontinen

Liposuction in Dercum's disease: impact on haemostatic factors associated with cardiovascular disease and insulin sensitivity.

OBJECTIVE: To study the impact of adipose tissue removal by liposuction on factors associated with increased risk of cardiovascular atherosclerotic disease within the coagulation and fibrinolytic system and glucose metabolism. DESIGN, SETTING AND SUBJECTS: Liposuction was performed in 53 patients with Dercum's disease. The levels of fibrinogen, von Willebrand factor antigen (VWF:Ag) and plasminoge

Modelling and Validation of Industrial Measurement Systems - Aspects of Quality and Human Factors

Popular Abstract in Swedish Denna avhandling validerar industriella mätsystem, där både de tekniska och mänskliga aspekterna innefattas. Syfte är att få bättre kunskap om den mätteknik som används för att kunna kvalitetsbestämma produkter och för att slutligen på ett mer pålitligt sätt kunna bestämma kvalitén på den tillverkande produkten. För att kunna göra detta föreslårs en metod som tar fram eAlthough there is a fairly large number of books and articles concerning the validation of technical measurement systems, there are only a few which take into account the whole measurement system consisting of both technical and non-technical aspects. A measurement system comprises both the measurement process and the human being who conducts the measurement. In this way, the human being may be a

Levator co-activation is a significant confounder of pelvic organ descent on Valsalva maneuver.

Objective A Valsalva maneuver is used clinically and on imaging in order to determine female pelvic organ prolapse. We have examined the Potential confounding effect of levator co-activation at the time of a Valsalva maneuver and the impact of repetition with biofeedback instruction. Methods Fifty nulliparous women at 36-38 weeks' gestation received 3D/4D translabial ultrasound investigation in th

On the interaction between adsorbed layers of monoolein and the lipase action on the formed layers

We used the Surface Force Apparatus (SFA) and ellipsometry techniques to study the interaction forces and the adsorption behavior of monoolein (MO), respectively. MO was adsorbed from water to a hydrophobised mica or silica surface. In addition the effect of added lipase, Thermomyces (Humicula) lanuginosa lipase (TLL), to an adsorbed layer of MO was investigated. The force versus distance curves b

Legal Ideals and Normative Realities : A case study of children's rights and child labor activity in Paraguay

Fredrika Bremer and the Writing of America

Hemmen i den nya verlden(1853-4) is novelist Fredrika Bremer's 3-volume travel diary in letter form, a literary account of her two years' travel in the United States and Cuba. Bremer wove, into the America she "wrote," a number of American authors and their works. Novelist Catharine Sedgwick and poet and socialite Anne C. Lynch exemplified for Bremer the right use of women's moral influence. Crit

The Role of Matrix Metalloproteinases in Leukocyte Transmigration in Murine Experimental Autoimmune Encephalomyelitis

Murine experimental autoimmune encephalomyelitis (EAE) is a commonly used model in the investigation of the human disease multiple sclerosis (MS), a debilitating inflammatory disease of the central nervous system (CNS). MS and EAE involve multiple steps, primarily, auto-antigenic leukocyte (mainly T-cells and macrophages) crossing the blood-brain barrier and later their invasion into the CNS where

Män, kvinnor & omsorg : En studie av omsorg som begrepp och handling i mans- och kvinnodominerade yrken

Syftet med denna avhandling var att undersöka omsorg som begrepp och handling och att se hur omsorg kan yttra sig under olika villkor. Avhandling innehåller en översikt över icke-feministiska och feministiska teorier och filosofier om omsorg samt en empirisk undersökning av uppfattningar om omsorg och omsorgshandlingar i fyra yrkesgrupper: fastighetsansvariga, kvarterspoliser, distriktssjukskötersThe aim of this study was to investigate care as concept and action and to see how care can be expressed in different conditions. The dissertation contains a survey of non-feminist and feminist theories of care and an empirical study of views of care and caring acts in four professional groups: janitors, neighbourhood police, district nurses, and home-helpers.

Left atrioventricular plane displacement determined by echocardiography: a clinically useful, independent predictor of mortality in patients with stable coronary artery disease

Background. Echocardiographically determined left atrioventricular plane displacement (AVPD) is strongly related to prognosis in patients with chronic heart failure and in postmyocardial infarction patients. We aimed at exploring whether AVPD, unlike ejection fraction, is related to mortality in patients with stable coronary artery disease (CAD). Methods and results. Atrioventricular plane displac

Nonmuscle Myosin motor of smooth muscle.

Nonmuscle myosin can generate force and shortening in smooth muscle, as revealed by studies of the urinary bladder from mice lacking smooth muscle myosin heavy chain (SM-MHC) but expressing the nonmuscle myosin heavy chains A and B (NM-MHC A and B; Morano, I., G.X. Chai, L.G. Baltas, V. Lamounier-Zepter, G. Lutsch, M. Kott, H. Haase, and M. Bader. 2000. Nat. Cell Biol. 2:371–375). Intracellular ca

Effects of ultrasound contrast agents on Doppler tissue velocity estimation

The combination of Doppler tissue imaging and myocardial contrast echocardiography has the potential to provide information about motion and perfusion of the myocardium in a single examination. The purpose of this study was to establish how the presence of ultrasound contrast agent (UCA) affects measurements of Doppler tissue velocities in vivo and in vitro. We performed echocardiography in 12 pat

The influence of vigilance on intraguild predation

Theoretical work on intraguild predation suggests that if a top predator and an intermediate predator share prey, the system will be stable only if the intermediate predator is better at exploiting the prey, and the top predator gains significantly from consuming the intermediate predator. In mammalian carnivore systems, however, there are examples of top predator species that attack intermediate
