In order to obtain a higher thermal efficiency, the inlet temperature of gas turbines is gradually increased. However, this increases the thermal load on the first stage vane endwall surface. Therefore, an advanced cooling technique must be implemented for the endwall cooling to ensure that the gas turbine operates safely. In the current study, effects of swirling coolant flow from the upstream sl
Background: Heparin-binding protein (HBP) is a neutrophil-derived protein advocated as a biomarker in sepsis. We evaluated plasma HBP as a predictor of post-injury sepsis in trauma patients. Methods: Ninety-seven trauma patients were studied during the first week of intensive care. Injury-related data were collected and clinical parameters registered daily. Plasma HBP was sampled on day 1, 3 and 5
HYPOTHESIS: The clinical and physiological features of patients with short segments of columnar-lined esophagus (CLE) with and without intestinal metaplasia (IM) are distinct.DESIGN: Retrospective case series.SETTING: University tertiary referral center.PATIENTS: Sixty-five consecutive patients with a 2-cm or shorter length of endoscopically visible CLE.INTERVENTIONS: The type of CLE and the prese
A sustainable renovation results in both a good indoor environment and high-energy efficiency. However, contemporary renovations often focus on energy and environmental performance, leaving out other aspects, such as the thermal comfort. The aim of the ongoing study is to compare the results of an extensive thermal environment evaluation before and after major renovation of ten typical 1970’s rent
The aim of the present study was to determine prevalence of voice problems and potential risk factors in teacher students at the start of their education. A total of 1494 students from seven teacher education schools participated in the study. The students answered a questionnaire about 11 risk factors, and one with six questions about voice symptoms, Screen6, and 30 statements in the Voice Handic
Corynebacterium is a genus that can contaminate blood cultures and also cause severe infections like infective endocarditis (IE). Our purpose was to investigate microbiological and clinical features associated with contamination and true infection. A retrospective population-based study of Corynebacterium bacteremia 2012–2017 in southern Sweden was performed. Corynebacterium isolates were species
The ability to recognize emotions undergoes major developmental changes from infancy to adolescence, peaking in early adulthood, and declining with aging. A life span approach to emotion recognition is lacking in the auditory domain, and it remains unclear how the speaker’s and listener’s ages interact in the context of decoding vocal emotions. Here, we examined age-related differences in vocal em
We present a sample of 705 local giant stars observed using the New Mexico State University 1 m telescope with the Sloan Digital Sky Survey-III/Apache Point Observatory Galactic Evolution Experiment (APOGEE) spectrograph, for which we estimate stellar ages and the local star formation history (SFH). The high-resolution (R ̃ 22,500), near infrared (1.51-1.7 μm) APOGEE spectra provide measurements o
Background and purpose — Obesity defined as increased BMI is commonly associated with higher revision rates following total knee arthroplasty (TKA). We examined the effect of BMI on the rate of revision after TKA, for both infection and other reasons, and analyzed weight and height separately to provide better understanding of the risk profile. Patients and methods — The Swedish national knee arth
Diabetic foot ulcer is a serious complication in patients with diabetes. In most outcome studies of this condition, there is a combination of various types of ulcer and ulcer locations. Plantar ulcers are usually localized to the forefoot, and constitute a quarter of all diabetic foot ulcers. There are a limited number of studies regarding development of new ulcers following healing of a plantar f
OBJECTIVES: Poor self-rated health is an estimator of quality of life and a predictor of mortality seldom studied in immigrant populations. This work aimed to study self-rated health in relation to social capital, socioeconomic status, lifestyle and comorbidity in immigrants from Iraq - one of the largest non-European immigrant group in Sweden today - and to compare it with the self-rated health o
Transcatheter aortic valve replacement (TAVR) is a rapidly growing field. Short-term safety and efficacy of these procedures have been studied extensively. However, little is known about the safety of these devices over time. Stroke is one feared long-term complication, and an increased stroke rate could affect guidelines for treating both the aortic stenosis and choosing antithrombotic therapy af
Cadmium (Cd) contamination and soil salinity are the main environmental issues reducing crop productivity. This study aimed to examine the combined effects of salinity (NaCl) and Cd on the physiological and biochemical attributes of quinoa (Chenopodium quinoa Willd.). For this purpose, 30-day-old plants of quinoa genotype “Puno” were transplanted in Hoagland's nutrient solution containing diverse
Background: A previous individual participant data (IPD) meta-analysis showed that the Wells rule and D-dimer testing cannot exclude suspected deep vein thrombosis (DVT) in cancer patients. Objectives: To explore reasons for this reduced diagnostic accuracy and to optimize the diagnostic pathway for cancer patients suspected of DVT. Patients and Methods: Using IPD from 13 studies in patients with
Aim: To compare vibrotactile sense, 5 years after carpal tunnel release in people with and without diabetes. Methods: Out of 35 people with diabetes and carpal tunnel syndrome, age- and gender-matched with 31 people without diabetes but with idiopathic carpal tunnel syndrome, 27 and 30 people, respectively, participated in this prolonged follow-up. Vibration perception threshold of the index and l
Warmer or cooler spring in northern high latitudes will, for the most part, directly impact gross primary productivity (GPP) of ecosystems, but also carry consequences for the upcoming seasonal GPP. Spatiotemporal patterns of these legacy effects are still largely unknown but important for improving our understanding of how plant phenology is associated with vegetation dynamics. In this study, imp
Bifidobacterium longum endo-α-N-acetylgalactosaminidase (GH101), EngBF, is highly specific toward the mucin Core 1 glycan, Galβ1-3GalNAc. Apart from the side chains involved in the retaining mechanism of EngBF, Asp-682 is important for the activity. In the crystal structures of both EngBF and EngSP (from Streptococcus pneumoniae), we identified a conserved water molecule in proximity to Asp-682 an
Background and purpose — Hip dislocation in cerebral palsy (CP) is caused by altered muscle forces on the joint during typical hip positioning in adduction–flexion–inward rotation. Preventive surgery includes adductor–psoas lengthening (APL) or varus derotation osteotomy (VDRO) of the proximal femur. We assessed the changes in the hip abduction range after these operations. Patients and methods —
AIM: We aim to compare machine learning with neural network performance in predicting R0 resection (R0), length of stay > 14 days (LOS), major complication rates at 30 days postoperatively (COMP) and survival greater than 1 year (SURV) for patients having pelvic exenteration for locally advanced and recurrent rectal cancer.METHOD: A deep learning computer was built and the programming environment
