Ultrasonic motor performance influenced by lubricant properties

Functional lubrication has been shown to be a promising method for improving the performance ofultrasonic motors (USMs). However, the complex lubrication mechanisms have not been studied and the effect of lubricant properties on motor performance remains unknown. In this paper, both low-traction fluids and high-traction fluids with a wide viscosity range are applied, and the lubricating effects ar

Physciosporin suppresses mitochondrial respiration, aerobic glycolysis, and tumorigenesis in breast cancer

BACKGROUND: Physciosporin (PHY) is one of the potent anticancer lichen compound. Recently, PHY was shown to suppress colorectal cancer cell proliferation, motility, and tumorigenesis through novel mechanisms of action.PURPOSE: We investigated the effects of PHY on energy metabolism and tumorigenicity of the human breast cancer (BC) cells MCF-7 (estrogen and progesterone positive BC) and MDA-MB-231

Physciosporin suppresses the proliferation, motility and tumourigenesis of colorectal cancer cells

BACKGROUND: Lichens, which represent symbiotic associations of fungi and algae, are potential sources of numerous natural products. Physciosporin (PHY) is a potent secondary metabolite found in lichens and was recently reported to inhibit the motility of lung cancer cells via novel mechanisms.PURPOSE: The present study investigated the anticancer potential of PHY on colorectal cancer (CRC) cells.M

Strategic coupling and institutional innovation in times of upheavals : the industrial chain chief model in Zhejiang, China

For regions that are deeply integrated into the global economy, the question of how to remain competitive and resilient in times of uncertainty is a key concern. While strategic coupling is a useful concept for understanding local-global economic dynamics, the idea that a region can simultaneously couple into multiple production networks organised at different spatial scales and that regional acto

Mg-doping and free-hole properties of hot-wall MOCVD GaN

The hot-wall metal-organic chemical vapor deposition (MOCVD), previously shown to enable superior III-nitride material quality and high performance devices, has been explored for Mg doping of GaN. We have investigated the Mg incorporation in a wide doping range (2.45 × 10 18 cm-3 up to 1.10 × 10 20 cm-3) and demonstrate GaN:Mg with low background impurity concentrations under optimized growth cond

Is the setting up aid mitigating the generational renewal problem in farming?

This study is the first to evaluate the setting up aid (SUA), in the Rural Development Programme. For Sweden, we investigate if the aid, firstly, speeds up the transition process to become manager of a farm and, secondly, affects income from farming and survival of the farm. The approach builds on a regression discontinuity design and explores an age 40-the eligibility requirement in the SUA. We f

Early menopause and weight loss are significant factors associated with risk of future fracture in middle-aged women

BACKGROUND: To identify factors related to reproductive history and weight change associated with first incident fracture in middle-aged women.METHODS: In total, 18,326 women from the Malmö Diet and Cancer study were included in this prospective population-based cohort study. Participants were included 1991-1996 and followed to 2016. Using data from the National Patient Registry, linked with every

Atomic structural mechanism for ferroelectric-antiferroelectric transformation in perovskite NaNbO3

Sodium niobate (NaNbO3 or NN) is described as "the most complex perovskite system,"which exhibits transitions between, as well as coexistence of, several ferroelectrics (FE) and antiferroelectric (AFE) phases at different temperatures. Recently, solid solutions of NN with stabilized AFE phases(s) have gained attention for energy-related applications, such as high-density energy storage and electro

Severe COVID-19 in people 55 and older during the first year of the pandemic in Sweden

Background: Exposure to many contacts is the main risk factor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, while risk of serious disease and death is chiefly determined by old age and comorbidities. Relative and population-attributable fractions (PAFs) of multiple medical and social exposures for COVID-19 outcomes have not been evaluated among older adults. Objective

”Fackliga argumentet låter som Storebror”

När Martin Linder argumenterar för kollektivavtal påminner det om Storebrors propagandafraser i George Orwells bok 1984: ”frihet är slaveri”, det vill säga frihet är tvång. Det skriver Lars Jonung i en slutreplik.

Hip prosthetic loosening and periprosthetic osteolysis : A commentary

Prosthetic loosening and periprosthetic osteolysis have been debated for decades, both in terms of the timing and nature of the triggering events. The hypothesis of wear-particle-induced loosening states that wear particles cause a foreign-body response leading to periprosthetic osteolysis and ultimately to late prosthetic loosening, i.e., that the osteolysis precedes the loosening. The theory of

Major adverse cardiovascular events following acute coronary syndrome in patients with bipolar disorder

Background: Persons with bipolar disorder (BD) have a higher cardiovascular mortality compared to the general population, partially explained by the increased burden of cardiovascular risk factors. Research regarding outcomes following acute coronary syndrome (ACS) in this population remains scarce. Design: This Danish register-based study included patients diagnosed with BD and ACS in the period

Urban civil defence : Imagining, constructing and performing nuclear war in Aarhus

During the Cold War, cities were seen as likely targets of modern total warfare and systems of civil defence were created to protect cities and their inhabitants. Yet existing civil defence histories have focused little on the specifically urban aspect, and urban historians likewise have paid civil defence little attention. Using Aarhus, Denmark, as a casestudy, this article examines civil defence
