Robotic surgery was developed to expand the patient population being offered a minimal invasive approach while retaining the associated advantages of minimal invasive surgery. Robotic surgery has been suggested to be particularly beneficial in surgery for malignant disease or in the presence of extensive intraabdominal adhesion, severe endometriosis, large uteri, high burden of comorbidity, or obe
Climate change is increasingly recognized as a major security concern, with drought–migration–conflict linkages attracting significant attention in both policy and research. While some narratives portray drought as a direct driver of migration and conflict, evidence shows a far more complex relationship: climate stress can lead to more migration in some contexts and less in others, with internal m
This thesis aims to advance our understanding of how directors’ values influence board decision-making and firm behavior by developing and testing a model that integrates insights from behavioral perspectives on boards of directors and corporate governance. Ideally, boards engage in intensive and open discussions that utilize the full cognitive capacity of their members. However, in practice, they
Emerging evidence suggests that bidirectional lung–kidney crosstalk may influence outcomes, but this has not been systematically evaluated in unselected emergency department populations. We therefore examined the association between peripheral oxygen saturation (SpO₂), estimated glomerular filtration rate (eGFR), and 30‑day mortality, and tested whether the prognostic association of oxygenation wi
Quantification using the Centiloid (CL) scale has become a valuable information to consider when interpreting amyloid-PET images and is now implemented in several software packages. This work aims to assess the comparability of CL from [18F]flutemetamol scans derived using several research and commercial quantification pipelines. Methods: This analysis relies on three datasets: a test-retest cohor
In this work, a method for registration of whole-body (WB) scintillation-camera images is presented. The primary motive for the development is to perform activity quantification using the conjugate view method on an image basis. Accurate image registration is required for sequential anterior and posterior scans, for serial emission images for analysis of the biokinetics, and for transmission and e
Popular Abstract in Swedish Avhandlingen behandlar frågan om vad man i Sverige brukar kalla "människovärde". Denna fråga belyses genom en analys av begreppen "livets helgd" och "livskvalitet" som i den anglo-saxiska debatten har kommit att symbolisera två helt olika sätt att tolka det mänskliga livet värde. Tanken om livets helgd brukar anföras av dem som tror att livets värde är inneboende och iThe principles of sanctity of life and quality of life are often appealed to in medical decisions at the "edges of life." Notwithstanding their importance in bioethics, these principles are still badly understood. This study is an attempt to clarify their normative significance and content. Because these principles pertain to the more general question of the value of life, the study begins by exp
Objectives We examined to what degree annoyance ratings to noise, air pollution and other common environmental factors in the home environment could be considered to mirror personality disposition in terms of habitual anxiety level and, when appropriate, objectively modeled noise and nitrogen emission (NOx). Methods A trait anxiety scale was introduced in a cross-sectional public health survey wit
In colostrum collected 0-80 h postpartum the contents of immunoglobulins (Igs), transforming growth factor beta-2 (TGF-beta2), insulin-like growth factor-1 (IGF-1) and growth hormone (GH) were analysed. Colostrum initially contained 90 mg mL(-1) IgG1, 2.8 mg mL(-1) IgG2, 1.6 mg mL(-1) IgA, 4.5 mg mL(-1) IgM, and these concentrations declined by 92%, 87%, 93% and 84%, respectively, in the samples c
Texture of potatoes with different shapes (slices and strips) were evaluated after frying and in some cases after baking. Blanched and unblanched potato slices (Bintje variety) were fried at four oil temperatures: 160, 170, 180 and 190C until reaching a moisture content of similar to1.7%. A puncture test with three point support for the slices was applied to measure the texture of potato chips usi
An eight-band k.p theory that does not suffer from the spurious solution problem is demonstrated. It is applied to studying the electronic properties of InP and InAs free-standing nanowires. Band gaps and effective masses are reported as a function of size, shape, and orientation of the nanowires. We compare our results with experimental work and with other calculations.
We investigated possible physiological effects of the application of anti-browning substances on metabolically active potato tissues. The use of citric acid, ascorbic acid and L-cysteine for browning prevention of fresh-cut potatoes increased their metabolic heat production as measured by isothermal calorimetry. This effect was particularly high after treatment with L-cysteine, which also proved t
Light (LM) and transmission electron (TEM) microscopy were used to study previously specified ozone symptoms in the foliage of Norway spruce. The three youngest green needle generations from twenty mature trees in two stands on sites of different soil fertility at Asa, southern Sweden, were sampled in 1999. The critical dose of ozone, expressed as AOT40, was 6362 ppb.h. LM showed ozone-specific sy
The effect of pulsed electric field (PEF) pretreatment on solid-liquid expression from potato tissue was studied on individual parenchyma tissue samples for different PEF intensities, varying relative deformations and deformation rates. The yield increased with relative deformation. The yield at any given relative deformation increased with increased PEF intensity and decreased deformation rates.
A method for simultaneous determination of 5-hydroxy-N-methylpyrrolidone and 2-hydroxy-N-methylsuccinimide in urine is described. These compounds are metabolites of N-methyl-2-pyrrolidone, a powerful and widely used organic solvent. 5-Hydroxy-N-methylpyrrolidone and 2-hydroxy-N-methylsuccinimide were purified from urine by adsorption to a C8 solid-phase extraction column and then elution by ethyl
In a prospective study of a consecutive breast cancer series accumulated in the period 1978-82, the S-phase fraction (SPF) and ploidy status were determined by flow cytometry performed on cell nuclei derived from samples of 580 primary tumors. Sixty percent of the tumors were non-diploid. After correction for debris the median SPF values were 7.3% overall, 12% for non-diploid tumors, and 2.9% for
Exposure to organic dust originating from biofuels can cause adverse health effects. In the present study we have assessed the dustiness in terms of microbial components and particles of various biofuels by using a rotating drum as a dust generator. Microbial components from straw, wood chips, wood pellets and wood briquettes were quantified by several methods. Excellent correllations (r greater t
Dimethyldodecylamine-N-oxide (DDAO) has only one polar atom that is able to interact with water. Still, this surfactant shows very hydrophilic properties: in mixtures with water, it forms normal liquid crystalline phases and micelles. Moreover, there is data in the literature indicating that the hydration of this surfactant is driven by enthalpy while other studies show that hydration of surfactan
With increasing age, human skeletal muscles gradually decrease in volume, mainly due to a reduced number of motor units and muscle fibers, and a reduced size of type 2 fibers. As a result, progressive weakening and impaired mobility occur. High-resistance strength training is beneficial, even in the very old, and could possibly reverse some of the detrimental effects of age-related weakness. The i
