In order to study the variation of vortices and heat transfer enhancement characteristics of piezoelectric vibrating cantilever in liquid-cooled channels, the effects of fluid density and viscosity, mainstream velocity, and excitation voltage on vortices were analyzed. The theoretical and numerical simulation of piezoelectric vortices was carried out by using fluid-solid coupling method. On the ba

This study investigated the idea that youth’s perceptions of the frequency of family political discussions and of parental political support mostly derive from their own political interest, a form of projection bias. Tests were performed of whether the same bias applies to parents, and whether youth’s and parents’ perceptions of political discussions and political support overlap to only a limited

Background: Caldicellulosiruptor kronotskyensis has gained interest for its ability to grow on various lignocellulosic biomass. The aim of this study was to investigate the growth profles of C. kronotskyensis in the presence of mixtures of glucose–xylose. Recently, we characterized a diauxic-like pattern for C. saccharolyticus on lignocellulosic sugar mixtures. In this study, we aimed to investiga

The core cerebrospinal fluid (CSF) Alzheimer's disease (AD) biomarkers amyloid beta (Aβ42 and Aβ40), total tau, and phosphorylated tau, have been extensively clinically validated, with very high diagnostic performance for AD, including the early phases of the disease. However, between-center differences in pre-analytical procedures may contribute to variability in measurements across laboratories.

We have developed a technique to measure low-power electromagnetic fields from mm-wave devices non-intrusively by combining a metasurface, designed to absorb power and focus the radiated power in a thermally isolated region, with an infrared camera. The metasurface consists of thermally isolated elements of low mass and highly emissive material for maximal IR conversion of the incident wave. The I

This is a report from the European Society of Gynaecological Oncology State-of-the-Art Virtual Meeting held December 14-16, 2020. The unique 3-day conference offered comprehensive state-of-the-art summaries on the major advances in the treatment of different types of gynecological cancers. Sessions opened with a case presentation followed by a keynote lecture and interactive debates with opinion l

Most of the studies on cutting mechanisms and surface integrity in turning are investigated with a straight tool path (longitudinal/end face turning) while few contributions have been done in curved surface turning. This work explores the evolutions of cutting force, chip morphology and surface integrity when turning a curved surface, using fillet surface machining of AISI 304 stainless steel. The

Diabetes mellitus (DM) is the most severe metabolic disease that reached the level of a global pandemic and is associated with high cardiovascular morbidity. Statins are the first-line lipid- lowering therapy in diabetic patients with or without a history of atherosclerotic disease. Although well tolerated, chronic treatment may result in side effects that lead to treatment interruption. Mitochond

BACKGROUND: Breastfeeding has beneficial effects on numerous health outcomes.OBJECTIVES: We investigated whether breastfeeding duration is associated with the development of early childhood autoimmunity, allergies, or obesity in a multinational prospective birth cohort.METHODS: Infants with genetic susceptibility for type 1 diabetes (n = 8676) were followed for the development of autoantibodies to

The AMP-activated protein kinase (AMPK) is a ubiquitously expressed kinase, which is activated in response to depletion of cellularenergy levels. Once active, it functions to alter cellular metabolism in a way that leads to restoration of energy levels. Therefore,AMPK is described as the key regulator of cellular energy homeostasis. Over the past years, AMPK activation has gained increasingattenti

Nätläkare, vårdgivare som tillhandahåller sjukvårdstjänster via smartphoneappar, har gått från att vara perifera inslag i den svenska sjukvården till att på allvar utmana det konventionella sättet att bedriva sjukvård. Den tillgänglighet som nätläkare erbjuder är oöverträffad men alla patientgrupper har inte sett sin tillgång till vård förbättras i samma utsträckning tack vare nätläkare.Syftet medOnline doctor services, healthcare provided via smartphone apps, have gone from being peripheral to seriously challenging the conventional Swedish way of providing healthcare services. The accessibility of online doctors is unsurpassed but all patient groups have not gotten better access to healthcare thanks to online doctors.The aim of this study was to investigate how perceptions of the online d

In the morning hours of April 11, the Natanz nuclear facility in Iran was attacked, allegedly by Israel. The strike came at a sensitive time, as Iran and world powers are discussing Washington’s return to the Joint Comprehensive Plan of Action (JCPOA) and the removal of sanctions. According to Israeli estimates, as the Islamic Republic does not wish to jeopardize a US return to the JCPOA, its resp

Continuous exposure to methane causes IrO2(110) films on Ir(100) to undergo extensive reduction at temperatures from 500 to 650 K. Measurements using in situ X-ray photoelectron spectroscopy (XPS) confirm that CH4 oxidation on IrO2(110) converts so-called bridging oxygen atoms (Obr) at the surface to HObr groups while concurrently removing oxygen from the oxide film. Reduction of the IrO2(110) fil

The sharing economy is not sustainable by default – search for images of bikesharing graveyards. But, with careful design of the business models that facilitate access over ownership, the sharing economy can increase intensity of use and material efficiency, contributing to sustainable consumption. In this episode, co-host Steven Curtis shares with us his research on sharing economy business model

Objectives: HLA-DQ2 and DQ8 contribute to the strongest risk haplotypes for type 1 diabetes (T1D) and celiac disease (CD). The variation in genetic risk association is likely linked to different HLA class II loci susceptibility, but association studies of HLA class I alleles are scarce. The aim was to investigate HLA class I A, B, and C alleles polymorphisms in children with only T1D, CD, and a su

Aims: A diabetic foot ulcer (DFU) is associated with increased cardiovascular risk and mortality, independently of ulcer etiology (ischemic, neuro-ischemic or neuropathic). Ankle–brachial index (ABI) is the most commonly used test when diagnosing peripheral macrovascular disease and is a well-known marker for increased cardiovascular risk. Transcutaneous oxygen pressure (TcPO2) is considered to be
