Conjugated heat transfer investigation with racetrack-shaped jet hole and double swirling chamber in rotating jet impingement

A numerical study is performed to investigate the effects of jet hole shape and channel geometry on impingement cooling for both stationary and rotating condition. Two hole shapes and two channel geometries are introduced to counteract the adverse effects of centrifugal force and Coriolis force which are induced by rotation. Both the fluid and solid part are considered for realizing the conjugate

Search for supersymmetry in final states with missing transverse momentum and multiple b-jets in proton-proton collisions at √s=13 TeV with the ATLAS detector

A search for supersymmetry involving the pair production of gluinos decaying via third-generation squarks into the lightest neutralino (χ˜10) is reported. It uses LHC proton-proton collision data at a centre-of-mass energy s=13 TeV with an integrated luminosity of 36.1 fb−1 collected with the ATLAS detector in 2015 and 2016. The search is performed in events containing large missing transverse mom

A critical evaluation of wet biomarkers for huntington's disease : Current status and ways forward

There is an unmet clinical need for objective biomarkers to monitor disease progression and treatment response in Huntington's disease (HD). The aim of this review is, therefore, to provide practical advice for biomarker discovery and to summarise studies on biofluid markers for HD. A PubMed search was performed to review literature with regard to candidate saliva, urine, blood and cerebrospinal f

Global metawebs of spider predation highlight consequences of land-use change for terrestrial predator–prey networks

Land-Use Change and Terrestrial Predator–Prey Networks Land-use change, here defined as the conversion of one land-use type into another (e.g., forest to arable land), affects biodiversity and biotic interactions worldwide (Sala et al., 2000). Although there has been large regional variation in the extent of agricultural expansion and abandonment in Europe in the past 50 years (Rabbinge and van Di

Quality of work in prostitution and sex work. Introduction to the special section

Increasingly, prostitution and other activities in the sex industries have been conceptualised as forms of labour, or at least as income-generating activities. As labour, these activities are exposed to particular risks with respect to health, working conditions, exploitation and stigmatisation. However, research on the actual conditions and circumstances existing in these markets, remains limited

Mechanical power curve measured in the wake of pied flycatchers indicates modulation of parasite power across flight speeds

How aerodynamic power required for animal flight varies with flight speed determines optimal speeds during foraging and migratory flight. Despite its relevance, aerodynamic power provides an elusive quantity to measure directly in animal flight. Here, we determine the aerodynamic power from wake velocity fields, measured using tomographical particle image velocimetry, of pied flycatchers flying fr

TEMPO-oxidised cellulose nanofibrils; Probing the mechanisms of gelation : Via small angle X-ray scattering

The structure of dispersions of TEMPO-oxidised cellulose nanofibrils (OCNF), at various concentrations, in water and in NaCl aqueous solutions, was probed using small angle X-ray scattering (SAXS). OCNF are modelled as rod-like particles with an elliptical cross-section of 10 nm and a length greater than 100 nm. As OCNF concentration increases above 1.5 wt%, repulsive interactions between fibrils

Association between post-diagnostic use of cholera vaccine and risk of death in prostate cancer patients

Recent evidence suggests that cholera toxin might have multiple functions regarding the ability to regulate the immune system. However, it is unknown whether subsequent administration of cholera vaccine might affect the mortality rate in patients with prostate cancer. Here we report that patients in Sweden, who were diagnosed with prostate cancer between July 2005 and December 2014 and used choler

Inter-rater agreement of the Quality of Life-Alzheimer's Disease (QoL-AD) self-rating and proxy rating scale : Secondary analysis of RightTimePlaceCare data

Background: To assess the quality of life of people with dementia, measures are required for self-rating by the person with dementia, and for proxy rating by others. The Quality of Life in Alzheimer's Disease scale (QoL-AD) is available in two versions, QoL-AD-SR (self-rating) and QoL-AD-PR (proxy rating). The aim of our study was to analyse the inter-rater agreement between self- and proxy rating

The Efficiency Index (EFFi), based on volumetric capnography, may allow for simple diagnosis and grading of COPD

Background: Spirometry, the main tool for diagnosis and follow-up of COPD, incompletely describes the disease. Based on volumetric capnography (VCap), an index was developed for the diagnosis and grading of COPD, aimed as a complement or alternative to spirometry. Methods: Nine non-smokers, 10 smokers/former smokers without COPD and 54 smokers/ former smokers with COPD were included in the study.

Re-igniting the afterglow plasma column of an AC powered gliding arc discharge in atmospheric-pressure air

The stability and re-ignition characteristics of the plasma column of an alternating current (AC) powered gliding arc discharge operating in atmospheric-pressure air were investigated for better plasma-mode controlling and optimized applications. By modulating the AC power supply and the air flow field, the states of afterglow plasma column were varied. When pulsating the AC power supply sequence,

Age and health-related quality of life, general self-efficacy, and functional level 12 months following dysvascular major lower limb amputation : a prospective longitudinal study

Aim: This study investigates the effect of time and age on health-related quality of life, general self-efficacy, and functional level 12 months following dysvascular major lower limb amputation (LLA). Methods: A prospective cohort study design with assessments at baseline and follow-up 3, 6, and 12 months post-amputation. Data were collected via in-person interviews using Short Form 36, the Gener

Songs that carry transformation : Pentecostal praise and worship rituals in Nairobi, Kenya

In this article, the theological meaning of transformation is examined from the vantage point of a local Pentecostal church in Nairobi, Kenya, and its liturgical practices. The church under study is the Woodley branch of Christ is the Answer Ministries (CITAM Woodley), formerly Nairobi Pentecostal Church (NPC) Woodley, and data was collected through field research. Arguing with the help of Steven

Interleukin-25 reduces Th17 cells and inflammatory responses in human peripheral blood mononuclear cells

Background: The absence of interleukin-25 (IL-25) favors the induction of Th1 and Th17 immune responses in mice. Th1 immune responses have been associated with the pathology of atherosclerosis, a lipid and inflammation driven disease of the arterial wall. Purpose of research: To evaluate the effect of IL-25 on human peripheral blood mononuclear cells (hPBMCs) in the presence and absence of oxidize

In-situ soot characterization of propane flames and influence of additives in a 100 kW oxy-fuel furnace using two-dimensional laser-induced incandescence

In-situ soot characterization has been successfully performed in a 100 kWth down-fired oxy-fuel test furnace using laser-induced incandescence (LII) and extinction measurements. Primarily non-premixed propane flames were investigated in oxy-fuel mode with various concentrations of oxygen in the oxidant. The turbulent flame character was manifested through two-dimensional single-shot LII signals fr

Validation of the Dyspnea Exertion Scale of Breathlessness in People With Life-Limiting Illness

Background: Although chronic breathlessness is common in life-limiting illnesses, validated feasible instruments to measure functional impact of the symptom in this population are scarce. We aimed to validate the Dyspnea Exertion Scale (DES) compared with the modified Medical Research Council (mMRC) breathlessness scale for test-retest reliability, concurrent validity, and responsiveness in people

The Merry-Go-Round of Meetings : Embracing Meetings in a Swedish Youth Care Project

Modern society has been called “a society of organizations,” and meetings are considered indispensable. However, a recurring cultural theme in contemporary working life is complaints about excessive and time-consuming meetings. The present article analyzes a contrasting case concerning a Swedish youth care project that employed a set of “coordinators” to maintain close contact with young people an
