A 180-deg turning channel can be seen in many heat exchange systems, and a strong three-dimensional flow phenomenon will occur at the turning point. In order to strengthen the heat transfer inside the turn and considering the lack of relevant enhanced endwall heat transfer approach, the present study innovatively demonstrates the measures of enhanced internal endwall heat transfer using arrays of
Malaria and helminthic co-infection during pregnancy causes fetomaternal haemorrhage and foetal growth retardation. This study determined the pooled burden of pregnancy malaria and helminthic co-infection in sub-Saharan Africa. CINAHL, EMBASE, Google Scholar, Scopus, PubMed, and Web of Science databases were used to retrieve data from the literature, without restricting language and publication ye
Background: Proficient Human Papillomavirus (HPV) genotyping services are essential to support HPV and cervical cancer elimination strategies, in particular to support HPV vaccine research. Objectives: To perform a global HPV genotyping proficiency study, with evaluation in relation to previous proficiency studies. Study design: The proficiency panel contained 44 coded samples (40 samples containi
Major atmospheric oxidants (OH,O3 and NO3) dominate the atmospheric oxidation capacity, while H2SO4 is considered as a main driver for new particle formation. Although numerous studies have investigated the long-term trend of ozone in Europe, the trends of OH, NO3 and H2SO4 at specific sites are to a large extent unknown. The one-dimensional model SOSAA has been applied in several studies at the S
Firekite is a synchronous stream cipher using a pseudo-random number generator (PRNG) whose security is conjectured to rely on the hardness of the Learning Parity with Noise (LPN) problem. It is one of a few LPN-based symmetric encryption schemes, and it can be very efficiently implemented on a low-end SoC FPGA. The designers, Bogos, Korolija, Locher and Vaudenay, demonstrated appealing properties
A number of instruments measuring psychological outcomes of falling exist, e.g. the Falls Efficacy Scale (FES). An extended version of the FES, the Falls Efficacy Scale-International (FES-I), has been developed and translated into several European languages. The aims of this study were to evaluate internal reliability, examine the internal structure of the FES-I(S) (the Swedish version of the FES-
The purpose of this work is to establish the critical surface conditions leading to the initiation of stress-corrosion cracks on the assupplied surfaces of three unidirectional E-glass/polymer composites with modified polyester, epoxy and vinyl ester resins subjected to a nitric acid solution without mechanical loads. The composite materials considered in this study are commonly used in composite
The present study experimentally demonstrates a novel design for an internal endwall in a two-pass duct heat exchanger. An array of delta-winglet vortex generator pairs with different aspect ratio, angle of attack, configuration are mounted on the internal endwall in a U duct. Liquid crystal thermalgraphy and static pressure measurements are utilized in this study to evaluate the heat transfer, th
Context. After more than two decades of relevant radial velocity surveys, the current sample of known brown dwarfs (BDs) around FGK stars is only of the order of 100, limiting our understanding of their occurrence rate, properties, and formation. The ongoing ESA mission Gaia has already collected more than its nominal 5 years of mission data, and is expected to operate for up to 10 years in total.
Cell culture techniques are strongly connected with modern scientific laboratories and production facilities. Thus, choosing the most suitable medium for the cells involved is vital, not only directly to optimise cell viability but also indirectly to maximise the reliability of the experiments performed with the cells. Fetal bovine or calf serum (FBS or FCS, respectively) is the most commonly used
Ulnar nerve compression at the elbow (UNE) frequently affects people of working age. Surgically treated patients may not immediately return to work (RTW) postoperatively. In 2008, the Swedish Social Insurance Agency reformed the national insurance policy. We aimed to examine RTW postoperatively for UNE, variations among surgical methods, and potential risk factors for prolonged RTW (sick leave > 6
Some microorganisms, like the aerobic soil bacteria, Oligotropha carboxidovorans, have the capability to oxidize the highly toxic atmospheric gas carbon monoxide (CO) into CO2 through CO dehydrogenase enzymes, whose active site contains a bimetallic MoCu center. Over the last decades, a number of experimental and theoretical investigations were devoted to understanding the mechanism of CO oxidatio
The study provides a new assessment of the water balance components of the catchment (evapotranspiration, surface and lateral flow etc., and its spatial distribution and temporal variability) for the transboundary catchment of Western Dvina river within the poorly gaged Russian part of the catchment. The study focuses on modeling the inland flow generation processes using open source data and the
Objectives To compile a battery of test including various aspects of physical fitness that could be used on the field and to assess whether any of these tests are associated with future traumatic knee injuries in youth female team sports athletes. Design Prospective cohort. Setting Sport setting. Participants Female athletes (n = 117, age 15–19 years), from Swedish sport high schools, active in so
Telomere length and telomere shortening are thought to be critical cellular attributes and processes that are related to an individual's life span and fitness. The general pattern across most taxa is that after birth telomere length gradually decreases with age. Telomere protection and restoration mechanisms are usually assumed to reduce the rate of shortening or at most keep telomere length const
IntroductionSpeech in children with cleft palate can be affected by velopharyngeal dysfunction, which persists after primary palate repair. The incidence of surgery to correct velopharyngeal dysfunction in this patient group has previously been reported as 2.6–37%. We aimed to investigate the incidence of velopharyngeal dysfunction surgery in Swedish children with cleft palate and to examine poten
Following the unrolling of 11QPsa, much attention has been paid to the question of its implications on the process of canonization of the Book of Psalms. Opposing positions have been carved out, mainly stressing either the secondary nature of the scroll, as compared to the MT-150 Book of Psalms, or its true canonical status. Much work has been done to organize the many psalms manuscripts into some
Objective: The aim of this study was to investigate whether self-administered Emotional Freedom Techniques (EFT) lead to reduced pain perception, increased acceptance and coping ability, and better health-related quality of life in individuals with fibromyalgia. Methods: Eighty-six women, diagnosed with fibromyalgia and on sick leave for at least 3 months, were randomly assigned to a treatment gro
