Study on Clay Core Replacement with Fiber Reinforced Concrete (Polypropylene) Core In the Rock-fill Dams

This paper is intended to present the results of an experimental investigation upon the possibility of clay core replacement with fiber (polypropylene) reinforced concrete core in rock‐fill dams. Within the rock‐fill dams, usually clayey soil is used as the main core material of the whole structure. Due to the fact that this kind of soil, being used; would have caused many problems such as; a huge

Bariatric surgery prior to total knee arthroplasty is not associated with lower risk of revision : a register-based study of 441 patients

Background and purpose — Obesity is a considerable medical challenge in society. We investigated the risk of revision for any reasons and for infection in patients having total knee arthroplasty (TKA) for osteoarthritis (OA) within 2 years after bariatric surgery (BS) and compared them with TKAs without BS. Patients and methods — We used the Scandinavian Obesity Surgery Registry (SOReg) and the Sw

The effects of tau, amyloid and white matter lesions on mobility, dual tasking and balance in older people

BACKGROUND: This study aimed to investigate whether white matter lesions (WML), β-amyloid- and tau pathologies are independently associated with mobility, dual tasking and dynamic balance performance in older non-demented individuals.METHODS: We included 299 older people (mean, SD, age: 71.8, 5.6 years) from the Swedish BioFINDER study, whereof 175 were cognitively unimpaired and 124 had mild cogn

Red deer allocate vigilance differently in response to spatio-temporal patterns of risk from human hunters and wolves

Ungulate prey can use increased vigilance to reduce their risk of predation, but little is known of the combined and interactive risk effects from humans and wolves in determining ungulate behaviour across time and space. Understanding the interplay between these risk effects is increasingly important, considering the recolonisation of several large carnivores to more human-dominated landscapes in

Artifacts in electrical measurements on wood caused by non-uniform moisture distributions

This paper examines how the moisture conditioning method affects the electrical conductance of wood. A widely used dataset was acquired by Stamm in 1929 who used a method of conditioning where water-saturated wood specimens were partially dried, sealed and left for a period of time for moisture to be redistributed before the electrical conductance was measured. However, more recent measurements co

The combination of clofarabine, etoposide, and cyclophosphamide shows limited efficacy as a bridge to transplant for children with refractory acute leukemia : results of a monitored prospective study

Clofarabine has been shown to effectively induce remission in children with refractory leukemia. We conducted a prospective trial (clinicval.trials.gov NCT01025778) to explore the use of clofarabine-based chemotherapy as a bridge-to-transplant approach. Children with refractory acute leukemia were enrolled to receive two induction courses of clofarabine, etoposide, and cyclophosphamide (CloEC). Re

Genomic and transcriptomic correlates of Richter's transformation in Chronic Lymphocytic Leukemia

The transformation of chronic lymphocytic leukemia (CLL) to high-grade B-cell lymphoma is known as Richter's Syndrome (RS) and it is a rare event with dismal prognosis. In this study, we conducted whole genome sequencing (WGS) of paired circulating CLL (PB-CLL) and RS biopsies (tissue-RS) from 17 clinical trial (CHOP-O) patients. We found that tissue-RS was enriched for mutations in poor-risk CLL

Hypercapnia in advanced chronic obstructive pulmonary disease : A secondary analysis of the national emphysema treatment trial

Rationale: Hypercapnia develops in one third of patients with advanced chronic obstructive pulmonary disease (COPD) and is associated with increased morbidity and mortality. Multiple factors in COPD are thought to contribute to the development of hypercapnia including increased carbon dioxide (CO2) production, increased dead space ventilation, and the complex interactions of deranged respiratory s

Determination of coefficients of friction for laminated veneer lumber on steel under high pressure loads

In this study, static coefficients of friction for laminated veneer lumber on steel surfaces were determined experimentally. The focus was on the frictional behaviors at different pressure levels, which were studied in combination with other influencing parameters: fiber orientation, moisture content, and surface roughness. Coefficients of friction were obtained as 0.10–0.30 for a smooth steel sur

Global torques and stochasticity as the drivers of massive black hole pairing in the young Universe

The forthcoming Laser Interferometer Space Antenna (LISA) will probe the population of coalescing massive black hole (MBH) binaries up to the onset of structure formation. Here, we simulate the galactic-scale pairing of ∼106 M☉ MBHs in a typical, non-clumpy main-sequence galaxy embedded in a cosmological environment at z = 7-6. In order to increase our statistical sample, we adopt a strategy that

Exploring reach and experiences of participation in health-promoting senior meetings in a municipality context

Aim: To explore reach and experiences of participants during implementation of health-promoting meetings of seniors in a Swedish municipality context. Subjects and methods: A mixed-methods approach was used, including older people who were recruited consecutively and invited to participate as they applied for health care and/or home help services in the municipality. Inclusion criterion was alloca

Occupation-focused health promotion for well older people-A cost-effectiveness analysis

Introduction: The aim of this study was to evaluate three occupational therapy interventions, focused on supporting continued engagement in occupation among older people, to determine which intervention was most cost effective, evaluated as the incremental cost/quality adjusted life year gained. Method: The study was based on an exploratory randomized controlled trial. Participants were 77-82 year

The prospective Hemophilia Inhibitor PUP Study reveals distinct antibody signatures prior to FVIII inhibitor development

Preventing factor VIII (FVIII) inhibitors following replacement therapies with FVIII products in patients with hemophilia A remains an unmet medical need. Better understanding of the early events of evolving FVIII inhibitors is essential for risk identification and the design of novel strategies to prevent inhibitor development. The Hemophilia Inhibitor Previously Untreated Patients (PUPs) Study (

High Luteinizing Hormone and Lower Levels of Sex Hormones in Younger Men With Distal Radius Fracture

This study investigates the sex steroid hormone profile in younger men with distal radius fracture (DRF) to elucidate if this could explain the low bone density and osteoporosis previously observed. In a case–control study, 73 men with DRF (mean age 38 ± 9 years; range, 20–51) was compared with 194 age-matched, population controls. Performed assays: total testosterone (TT), calculated free testost
