Purpose - The dimple is adopted into a pin fin wedge duct which is widely used in modern gas turbine vane cooling structure trailing edge region. The purpose of this paper is to study the effects of dimple depth and duct converging angle on the endwall heat transfer and friction factor in this pin fin wedge duct. Design/methodology/approach - The study is carried out by using the numerical simulat
This report presents basic concepts around resources, resource efficiency and the Circular Economy. The limitations and the opportunities within the Circular Economy are identified and clearly presented. The current policy landscape in the EU as well as in Sweden is thoroughly analysed and a set of policy areas with a significant untapped potential for resource efficiency is identified. The policy
The study of airborne bacteria relies on a sampling strategy that preserves their integrity and in situ physiological state, e.g. viability, cultivability, metabolic activity, and ice-nucleation activity. Because ambient air harbors low concentrations of bacteria, an effective bioaerosol sampler should have a high sampling efficiency and a high airflow. We characterize a high-flow-rate impinger wi
In recent years, researchers worldwide have become increasingly interested in the phenomenon of code-switching in the multilingual classroom. The paper aims to try to understand when and why teachers in Swedish for Immigrants (SFI) schools code-switch in their classrooms. It analyses the methods and reasons for teachers’ code-switching in the SFI classroom. A case study was conducted by means of a
The axiom of transitivity states that if a person prefers option A to B and B to C, he must also prefer A to C. This simple axiom is often seen as one of the pillars of rational choice, but whether it should be has created a divide in the research community. Some state that there cannot be rational choice or utility without transitivity and that agents who present intransitive preferences allow th
Adaptation of modern Unmanned Aerial Vehicle (UAV) and multispectral sensor technology in agriculture can enhance the capacity to accurately monitor crops. But these technologies come with its own set of challenges. The major challenge is the understanding of radiometric distortions, which is particularly important while comparing data over different lighting conditions. The study developed and as
The online-coupled 3-D chemistry transport model COSMO-MUSCAT was enhanced by a detailed description of aqueous phase chemical processes. The aqueous phase chemistry is represented by the detailed chemical mechanism CAPRAM 3.0i reduced (C3.0RED). In addition, the deposition schemes were improved in order to account for the deposition of matter incorporated in cloud droplets of ground layer clouds
There is a scarcity of instruments for assessing opportunities for residentswith psychiatric disabilities to engage in meaningful home-based activities.We thus developed the Perceived Meaning of Activity in Housing (PMA-H),containing four subscales (activity opportunities, social interaction, developingas a person, and organization and planning). The aim of the study was to investigate the content
People with psychiatric disabilities need to be able to express their views about their support, for example, the provision of meaningful activity in supported accommodation. Brief scales may be necessary to avoid strain and discomfort for this group. The aim was to develop a brief version of Perceived Meaning in Activity—Housing (PMA-H) an
Time-domain induced polarization (TDIP) data carry spectral information that can be used for petrophysical interpretation. At the same time, TDIP data can be collected in the field more efficiently than frequency-domain induced polarization (FDIP) data, thanks to the use of square-wave signals. However, TDIP field data are prone to noise, particularly strong near industrial installations and urban
IntroductionUse of long-term oxygen therapy (LTOT) for more than 15 h per day does not reduce mortality or hospitalizations, but may increase the risk of adverse events. We evaluated the relationship between daily oxygen use duration and adverse events, symptoms, and health status in patients on LTOT.MethodsThis was a cross-sectional survey study of a random sample (N = 650) of adults with ongoing
Background: Obstetrical anal sphincter injuries are complications of vaginal birth that have the potential to cause substantial maternal morbidity. Predicting these injuries might help to improve maternal care as well as antenatal counseling and patient education. Previous attempts to create prediction models have in many cases involved variables only known postpartum, which limits their use in an
The effect of postharvest long-term storage and pre-treatments on the mass transfer rates during osmotic dehydration of carrots was investigated. Four blanching times were used and the carrots were sampled during 12 weeks of storage. Cell vitality was measured by isothermal calorimetry on cores taken from blanched slices. During the storage period, effective diffusion coefficients for water and su
As a second major result we show how to combine the path cover technique with LCA solutions for dags with small depth [9]. Our algorithm attains the best known upper time bound for this problem of O(n 2.575). However, most notably, the algorithm performs better on a vast amount of input dags, i.e. dags that do not have an almost linear-sized subdag of extremely regular structure. Finally, we appl
These guidelines are for practicing orthopedic surgeons who do not have a special interest in treatment of osteoporosis or prevention of falls, but who should have basic knowledge about how to prevent new fractures.
Increased QT dispersion and loss of sinus rhythm were both associated with sudden cardiac death in patients with transposition of the great arteries after Mustard and Senning operations at the early and late postoperative periods. A combination of increased QT dispersion with loss of sinus rhythm increases the positive predictive value for sudden cardiac death in patients with transposition of the
Vegetation is an important component in the Earth system, providing a direct link between the biosphere and atmosphere. As such, a representative vegetation pattern is needed to accurately simulate climate. We attempt to model global vegetation (biomes) with a data-driven approach, to test if this allows us to create robust global and regional vegetation patterns. This not only provides quantitati
The aim of this study was to establish creatinine growth curves separately for males and females that can be used to adjust childhood levels of serum creatinine to corresponding adult levels. Linear regression with fractional polynomials of age as independent variable was used to construct creatinine growth curves for a reference cohort (n = 83,157 samples from Belgium and Sweden, age 2–40 years).
