The free energy of nonionic balanced microemulsions based on nonionic surfactants are analyzed using experimental data from (i) phase behavior, (ii) osmotic compressibility of the balanced microemulsion structure, which is obtained from small angle neutron scattering (SANS) experiments, and (iii) data on interfacial tensions obtained by T. Sottmann and R. Strey [J. Chem. Phys. 106 8606 (1997)]. Th
In order to study the early cellular response in the fluid phase found close to implants in soft tissues, an experimental method using a hollow implant was developed. The fluid present in an interior chamber communicating with the exterior of the implant was analysed. Polymorphonuclear granulocytes (PMNGs) were predominant during the study (1-9 days). In titanium implants a slight increase in cell
BACKGROUND: Job strain, defined as high job demands and low job control, has not previously been explored as a possible determinant of male fertility. We collected prospective data on job strain among men, and describe the associations with semen quality and probability of conceiving a clinical pregnancy during a menstrual cycle. METHODS: Danish couples (N = 399) who were trying to become pregnant
The objective of this study was to evaluate different methodologies with regard to their ability to extract the amorphous silica (ASi) content of soils from diverse geochemical settings. The methods used in this work included three acid extraction techniques (oxalate, citrate and acetate) and two alkaline extraction techniques (sodium carbonate and sodium hydroxide) which are more commonly used fo
[1] Results from two deep sea cores from northeast of Newfoundland at 1251 and 2527 m water depth, respectively, indicate that during the time period from 160,000 to 10,000 years BP, ice rafting events in the Labrador Sea were accompanied by rapid variations in deep and surface water circulation. Twelve ice-rafting events occurred, each coinciding with high concentrations of detrital carbonate and
Variable temperature photoemission studies in the literature have revealed the presence of a surface state above the Fermi level on clean Ge(001). We present photoemission and low energy electron diffraction results from Ge(001) obtained between 185 and 760 K. Our measurements show a peak above the Fermi level with a maximum intensity at a sample temperature of around 625 K. At higher temperatures
As deep learning methods become more frequent in medical imaging, model explainability becomes essential in order to ensure trust. Gradient-weighted class activation mapping (Grad-CAM) is a widely used technique for visualizing which regions of an input contribute to a network’s decision. In this work, we introduce a novel Grad-CAM–based loss function that leverages prior knowledge of target regio
Abstract Course: SMTX06, Bachelor of degree. 15 hp. Spring 2009 Authors: Amir Amini Harati, Nosherwan Bajwa, Daniel Djukic Title: Where is the border? – A case study of the processes in IKEA Customerservice center Supervisors: Jan E. Persson, Mattias Wengelin Aim: The purpose of this study is to identify the problems within the borders between the processes in service companies. By making a map of
Uppsatsen inom Service Management vid Lunds Universitet, campus Helsingborg, behandlar den problematik som kan uppstå kring spridandet av ett företags identitet till dess franchiseenheter. Syftet med uppsatsen är att se hur en utomstående ägare till en enhet kan påverka hur företagets identitet sprids och bibehålls. Vår primära metod har varit intervjuer med personer som har nära anknytning till I
Introduction. The aetiology and pathogenesis of ulcerative colitis (UC) are essentially unknown. Galectins are carbohydrate-binding lectins involved in a large number of physiological and pathophysiological processes. Little is known about the role of galectins in human UC. In this immunohistochemical exploratory study, both epithelial and inflammatory cell galectin expression were studied in pati
Phenotypic divergence in allopatry can facilitate speciation by reducing the likelihood that individuals of different lineages hybridise during secondary contact. However, few studies have established the causes of reproductive isolation in the crucial early stages of secondary contact. Here we establish behavioural causes of assortative reproduction between two phenotypically divergent lineages o
Pollen analysis was made on a profile from the wetland complex Rolands Hav, Blekinge. The aim of the study was to investigate and document the development of the vegetation. The wetland area of Rolands Hav has developed during more than 10 000 years. The stratigraphy of this area will reveal valuable information about environmental changes during this time. The results of the pollen analysis is pr

The aim of this study was to perform histopathological reassessment of primary resections of locally advanced colon cancer (CC) within a randomized controlled trial, with specific focus on surgical margins and synchronous locoregional peritoneal metastases (SL-PM), and to provide learning points for both surgeons and pathologists. All histopathological slides of patients with c/pT4N0-2M0 or perfor
PURPOSE: To examine sex differences in health-related quality of life (HRQoL) among patients surgically treated for renal cell carcinoma (RCC) in Sweden, utilizing data from the National Swedish Kidney Cancer Register (NSKCR).METHODS: In this study of 4658 surgically treated RCC patients, data on HRQoL, clinical, demographic, and socioeconomic characteristics were retrieved from the NSKCR for pati
