The task consisted in helping Tetra Pak with the problem that they today have with unexplained deformation of their creasing carriages. Tetra Pak uses different carriages depending on which kind of packaging that is to be manufactured. The carriages are hauled in and pulled in to the production line when another type of packaging is to be manufactured. Basically the carriages look the same, the th
A novel design of a biochemical oxygen demand (BOD) biosensor has been developed for on-line monitoring of easily biodegradable organic compounds in aqueous samples. The biological recognition element of the sensor could be easily renewed by injecting new bacterial paste without disassembling the sensor system. The sensor measurements were carried out in the initial-rate mode using a flow injectio
Background In vivo measurement of wear in the ball and socket articulation of total hip arthroplasties is of interest in the evaluation of both existing and new implants. Controversy reigns regarding the accuracy of different radiological measurement techniques and in particular how accuracy has been assessed. Material and methods We assessed the accuracy of 2 radiostereometric (RSA) techniques f
Screening women for lower genital tract infection with Chlamydia trachomatis is important in the prevention of pelvic inflammatory disease, ectopic pregnancy and infertility. This systematic review aims to state clearly which of the available diagnostic tests for the detection of C. trachomatis would be most effective in terms of clinical effectiveness. The review included all studies published fr
Background. Umbilical artery Doppler velocimetry is a routine method for fetal surveillance in high-risk pregnancy. Uterine artery Doppler seems to give comparable information, but it can be difficult to interpret as there are two arteries, which might show notching and/or increased pulsatility index (PI) as signs of increased vascular impedance. Combining the information on vascular resistance on
Background Studies from low-income countries have suggested that diphtheria-tetanus-pertussis (DTP) vaccine provided after Bacille Calmette-Guerin (BCG) vaccination may have a negative effect on female survival. The authors examined the effect of DTP in a cohort of low birthweight (LBW) infants. Methods 2320 LBW newborns were visited at 2, 6 and 12 months of age to assess nutritional and vaccinati
Aim of the study: Endocrine treatment (ET) is an alternative as salvage therapy in epithelial ovarian cancer (EOC) but the usage in routine care is unknown. We evaluated the treatment patterns and outcome of patients receiving ET for EOC in the Southeast medical region in Sweden. Method: Patients were identified through the population-based Southeast Quality Registry for gynaecological cancer. Inc
We present mass models of the Milky Way created to fit observational constraints and to be consistent with expectations from theoretical modelling. The method used to create these models is that demonstrated in our previous study, and we improve on those models by adding gas discs to the potential, considering the effects of allowing the inner slope of the halo density profile to vary, and includi
Objective: Population-based osteoarthritis (OA) cohorts provide vital data on risk factors and outcomes of OA, however the methods to define OA vary between cohorts. We aimed to provide recommendations for combining knee and hip OA data in extant and future population cohort studies, in order to facilitate informative individual participant level analyses. Method: International OA experts met to m
In this study, we present the development of a mobile system to measure real-world total respiratory tract deposition of inhaled ambient black carbon (BC). Such information can be used to supplement the existing knowledge on air pollution-related health effects, especially in the regions where the use of standard methods and intricate instrumentation is limited. The study is divided in two parts.
Background: A common complaint by people with tinnitus is that they experience that the tinnitus causes attention and concentration problems. Previous studies have examined how tinnitus influences cognitive performance on short and intensive cognitive tasks but without proper control of hearing status. Purpose: To examine the impact tinnitus and high-frequency hearing thresholds have on reading co
Objective: To assess function using the Signals of Functional Impairment (SOFI) instrument over 8 years, to study clinical variables associated with the change, and to study change over time of the SOFI items. Methods: In total, 1,223 patients with early rheumatoid arthritis (RA) from the Better Anti-Rheumatic Farmacotherapy (BARFOT) cohort (mean ± SD age 56.9 ± 15.4 years, 67% women) were include
The shape and diversity of dwarf galaxy rotation curves is at apparent odds with dark matter halos in a Λ Cold Dark Matter (ΛCDM) cosmology. We use mock data from isolated dwarf galaxy simulations to show that this owes to three main effects. Firstly, stellar feedback heats dark matter, leading to a `coreNFW' dark matter density profile with a slowly rising rotation curve. Secondly, if close to a
Tissue factor (TF) expressed at the protein level includes two isoforms: The membrane‑bound full‑length TF (flTF) and the soluble alternatively spliced TF (asTF). flTF is the major thrombogenic form of TF, whereas asTF is more closely associated with tumor growth, angiogenesis, metastasis and cell growth. In order to further investigate the different expression and functions of TF splice variants,
Introduction: Traditional validation of umbilical cord blood samples with positive veno-arterial ΔpH and arterio-venous ΔpCO2 values confirms the source of samples, whereas negative Δvalues represent mix-up of samples. To investigate whether this is true, the distributions of V-A ΔpO2 and A-V Δlactate were also explored and related to clinical characteristics. In addition, different cord blood sam
Background: Existing research shows that older people with severe mental health problems need different forms of support in daily life and in the community to lead an active and meaningful life. A common form of support for people with severe mental health problems in Sweden is attendance at community-based day centres (DCs). However, knowledge of staff and managers’ experiences of how people agei
