Cleaning of simple cohesive soil layers in a radial flow cell

A radial flow cell (RFC, inlet tube radius 0.95 mm and gaps of 1–4.2 mm) was used to investigate the removal of two thin (80–230 µm thick) model soil layers from glass and 304 stainless steel substrates by the flow of water at 20 °C. Under the flow conditions employed (Reynolds numbers 200–1400), inertial effects give rise to recirculation zones and regions of high shear stress on the bottom, soil

Prostate-specific kallikrein-related peptidases and their relation to prostate cancer biology and detection

Kallikreins are a family of serine proteases with a range of tissue-specific and essential proteolytic functions. Among the best studied are the prostate tissue-specific KLK2 and KLK3 genes and their secreted protease products, human kallikrein 2, hk2, and prostate-specific antigen (PSA). Members of the so-called classic kallikreins, these highly active trypsin-like serine proteases play establish

Prostate cancer early detection : Clinical practice guidelines in oncology™

Since the early 1990s, many variants of the tPSA assay have been introduced to increase the sensitivity of screening programs (cancer detection) while maintaining specificity (elimination of unnecessary biopsies). Again, these guidelines recommend ways that individuals and their physicians can use these new techniques rationally for early detection of prostate cancer. These guidelines are not desi

Learning from the past to plan for the future : A scoping review of musculoskeletal clinical research in Sweden 2010-2020

Background: The aims of this study are to 1) determine the scope of musculoskeletal (MSK)-related clinical research in Sweden; 2) collate the amount of first-tier funding received; 3) discuss strategies and infrastructure supporting future MSK clinical trials in Sweden. Methods: A systematic scoping review protocol was applied in PubMed, Scopus, and SweCRIS databases. The articles were examined, a

Axonal degeneration and amyloid pathology predict cognitive decline beyond cortical atrophy

Background: Cortical atrophy is associated with cognitive decline, but the association is not perfect. We aimed to identify factors explaining the discrepancy between the degree of cortical atrophy and cognitive decline in cognitively unimpaired elderly. Methods: The discrepancy between atrophy and cognitive decline was measured using the residuals from a linear regression analysis between change

Multi-gigawatt peak power post-compression in a bulk multi-pass cell at a high repetition rate

The output of a 200 kHz, 34 W, 300 fs ytterbium amplifier is compressed to 31 fs with >88% efficiency to reach a peak power of 2.5 GW, which to date is a record for a single-stage bulk multi-pass cell. Despite operation 80 times above the critical power for self-focusing in bulk material, the setup demonstrates excellent preservation of the input beam quality. Extensive beam and pulse characteriza

The Kenevo microprocessor-controlled prosthetic knee compared with non-microprocessor-controlled knees in individuals older than 65 years in Sweden : A cost-effectiveness and budget-impact analysis

Background:Growing evidence suggests that individuals with transfemoral amputation or knee disarticulation using a prosthesis equipped with a microprocessor-controlled knee (MPK) benefit from enhanced mobility and safety, including less falls. In elderly individuals, high mortality rates are assumed to reduce the expected useful life of MPKs, and this raises concerns regarding their economic effec

Safety and usability of wearable accelerometers for stroke detection the STROKE ALARM PRO 1 study

Objectives: The introduction of time-dependent reperfusion therapies in acute ischemic stroke has increased the need for early identification. We explore the safety and feasibility of STROKE ALARM which detects sudden arm paresis, the most frequent symptom in stroke. Materials and methods: Consecutive patients admitted with a stroke or TIA at Skåne University Hospital were screened according to in

Expansionary Fiscal Policy and the Gender Employment Gap: Evidence from the Republic of Korea

The employment effects of expansionary fiscal policy have been well documented in the literature. Interestingly, however, limited attention has been paid to the gender dimension. Across countries, significant gaps in female and male employment still remain. This, together with the risk of hysteresis, makes it central to examine how expansionary fiscal policies affect female and male employment and

Backscatter Communications for 6G

The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the

Mental Health Support and its Cultural Understanding – A comparative study on the impacts of humanitarian aid in the context of IDP camps in Iraqi Kurdistan.

Mental health issues are a serious matter with great consequences on livelihoods. Iraqi Kurdistan is situated in one of the most unstable regions and experienced an influx of IDPs over time who are in need of mental health support. However, mental health support is shaped and understood differently according to the culture. The purpose of this research is therefore to investigate the consequences

Between theory and practice: Multifunctionality as a key concept for sustainable forest management? A systematic literature review of multifunctional forest management in Germany, Sweden, and Finland.

The intensification of forest management over the recent decades, in combination with the effects of a warming climate, leaves forestry and forest management with the challenging task of maintaining forest ecosystems’ further abilities to provide ecosystem services. By systematically reviewing peer- reviewed academic literature this study analyzes the concept of multifunctionality and its applicat

EAU-EANM Consensus Statements on the Role of Prostate-specific Membrane Antigen Positron Emission Tomography/Computed Tomography in Patients with Prostate Cancer and with Respect to [177Lu]Lu-PSMA Radioligand Therapy

BACKGROUND: Prostate-specific membrane antigen (PSMA) positron emission tomography (PET)/computed tomography (CT) is useful for selected clinical indications in patients with prostate cancer (PCa) but it may have broader clinical utility owing to the emergence of lutetium-177-PSMA-617 ([177Lu]Lu-PSMA) therapy. However, robust data regarding the impact of PSMA PET/CT on patient management and treat

Maternal Exposure to Per- and Polyfluoroalkyl Substances (PFAS) and Male Reproductive Function in Young Adulthood : Combined Exposure to Seven PFAS

BACKGROUND: Concerns remain about the human reproductive toxicity of the widespread per- and polyfluoroalkyl substances (PFAS) during early stages of development. OBJECTIVES: We examined associations between maternal plasma PFAS levels during early pregnancy and male offspring reproductive function in adulthood. METHODS: The study included 864 young men (age range:18.9-21.2 y) from the Fetal Progr

FELL ALGEBRAS, GROUPOIDS, AND PROJECTIONS

Examples of Fell algebras with compact spectrum and trivial Dixmier-Douady invariant are constructed to illustrate differences with the case of continuous-trace C∗-algebras. At the level of the spectrum, this translates to only assuming the spectrum is locally Hausdorff (rather than Hausdorff). The existence of (full) projections is the fundamental question considered. The class of Fell algebras s

Factors associated with exclusive breastfeeding at discharge during the COVID-19 pandemic in 17 WHO European Region countries

BACKGROUND: Exclusive breastfeeding is the optimal infant nutrition, providing infants immunoprotection against many diseases including SARS-CoV-2 infection. Restrictions during the COVID-19 pandemic may have negatively affected breastfeeding practices in maternity care facilities. The aims of the study were to examine exclusive breastfeeding rates at discharge over time and to identify factors as
