Screening Environmental Impact Reduction Enabled by Brass Reclamation through Hot Forging Operations

The traditional method for recycling brass chips is to send the scrap back to the material manufacturer for re-melting. Alternatively, brass chips can be reclaimed through hot forging operations at the production site. As an initial screening of the environmental impact of this novel reclamation method, the impacts of this new method was compared to conventional brass production (including recycli

Deterministic lateral displacement systems with arrayed three-dimensional electrodes for tunable particle sorting

Deterministic Lateral Displacement (DLD) is a passive technique employed for particles sorting. We recently introduced a DLD device composed of arrayed three-dimensional metal-covered pillars that can be used to locally apply an electric field. With our system we can exploit the dielectrophoretic (DEP) effect to exert forces on the bioparticles to be sorted, thus dynamically tuning the critical si

Enforcing the General Planar Motion Model : Bundle Adjustment for Planar Scenes

In this paper we consider the case of planar motion, where a mobile platform equipped with two cameras moves freely on a planar surface. The cameras are assumed to be directed towards the floor, as well as being connected by a rigid body motion, which constrains the relative motion of the cameras and introduces new geometric constraints. In the existing literature, there are several algorithms ava

Heritage in Action : Crafting collections between vernacular and institutional culture

This article is based on ethnographic fieldwork and applies theories of crafting and performance to explore how living heritage practices are rethought, reframed, and refashioned when traditional dress and individual garments are moved, reorganized, and transformed into a collection following rationales derived from both family tradition and museum standards. By following one woman’s emerging coll

Mortality with paclitaxel-coated devices in peripheral artery disease

BACKGROUND The results of a recent meta-analysis aroused concern about an increased risk of death associated with the use of paclitaxel-coated angioplasty balloons and stents in lower-limb endovascular interventions for symptomatic peripheral artery disease. METHODS We conducted an unplanned interim analysis of data from a multicenter, randomized, open-label, registry-based clinical trial. At the

Dealing with contaminants in Coulomb excitation of radioactive beams

Data analysis of the Coulomb excitation experiment of the exotic 206Hg nucleus, recently performed at CERN's HIE-ISOLDE facility, needs to account for the contribution to target excitation due to the strongly-present beam contaminant 130Xe. In this paper, the contamination subtraction procedure is presented.

Restoration of the electrocardiogram during mechanical cardiopulmonary resuscitation

Objective: An artefact-free electrocardiogram (ECG) is essential during cardiac arrest to decide therapy such as defibrillation. Mechanical cardiopulmonary resuscitation (CPR) devices cause movement artefacts that alter the ECG. This study analyzes the effectiveness of mechanical CPR artefact suppression filters to restore clinically relevant ECG information. Approach: In total, 495 10 s ECGs were

Response of heterogeneous rainfall variability in East Asia to Hadley circulation reorganization during the late Quaternary

The Quaternary East Asian summer rainfall evolution reconstructed with the Chinese speleothem δ18O records shows the consistency throughout the region of East Asia, and has long been considered equivalent to the monsoon intensity. Its variation and teleconnection with global climate were usually interpreted by the meridional shift of the intertropical convergence zone (ITCZ). However, many other p

Pre-processing for image quality improvement in simultaneous DBT and mechanical imaging

Simultaneous digital breast tomosynthesis (DBT) and mechanical imaging (MI) offer the potential to combine anatomic information from DBT with functional information from MI. This makes it possible to associate tissue stiffness with specific anatomic structures in the breast, a combination that can reduce false-positive findings by using the MI data to discriminate between ambiguous lesions in DBT.

Orphan G-protein coupled receptor 183 (GPR183) potentiates insulin secretion and prevents glucotoxicity-induced β-cell dysfunction

The expression and functional impact of most expression orphan G-protein coupled receptors (GPCRs) in β-cell is not fully understood. Microarray expression indicated that 36 orphan GPCRs are restricted in human islets, while 55 receptors overlapped between human islets and INS-1 cells. GPR183 showed higher expression in diabetic compared to non-diabetic human islets. GPR183 expression co-localized

Vestibular rehabilitation in Europe : a survey of clinical and research practice

Vestibular rehabilitation (VR) is practiced across Europe but little in this area has been quantified. The aim of this study was to investigate current VR assessment, treatment, education, and research practices. This was an online, cross-sectional survey with 39 VR specific questions and four sections: demographics, current practice, education, and research. The survey was disseminated through th

Molecular tests support the viability of rare earth elements as proxies for fossil biomolecule preservation

The rare earth element (REE) composition of a fossil bone reflects its chemical alteration during diagenesis. Consequently, fossils presenting low REE concentrations and/or REE profiles indicative of simple diffusion, signifying minimal alteration, have been proposed as ideal candidates for paleomolecular investigation. We directly tested this prediction by conducting multiple biomolecular assays

The myth of return

The Syrian conflict is far from over and the return of Syrian refugees is not indicative of mass influx into the country. Syrian refugees and their return have been instrumentalised and used as a politicai card and refugees should not be forced to return, as this would lead to further displacement and turmoil. Effective and consistent policies based on human rights, justice and accountability must

NKT cells promote both type 1 and type 2 inflammatory responses in a mouse model of liver fibrosis

Sterile liver inflammation and fibrosis are associated with many liver disorders of different etiologies. Both type 1 and type 2 inflammatory responses have been reported to contribute to liver pathology. However, the mechanisms controlling the balance between these responses are largely unknown. Natural killer T (NKT) cells can be activated to rapidly secrete cytokines and chemokines associated w

Clinical pre-test probability adjusted versus age-adjusted D-dimer interpretation strategy for DVT diagnosis : A diagnostic individual patient data meta-analysis

Background: To increase the clinical usefulness of the D-dimer test in diagnosis of deep vein thrombosis (DVT), two strategies have been proposed: the age-adjusted, and the clinical pre-test probability (CPTP) adjusted interpretation. However, it is not known which of these strategies is superior. Objective: To conduct an individual patient data (IPD) meta-analysis that compares the sensitivity, s

A feedforward approach to mid-ranging control

Mid-ranging control is a control strategy that is used when there are more than one manipulated variable available to control a process variable. Mid-ranging control handles the redundancy by coordinating the roles of the different manipulated variables. The most common approach is to introduce valve position controllers (VPC) that control the relations between the manipulated variables. In this p

Promote social participation among older persons by identifying physical challenges – An important aspect of preventive home visits

Introduction: Social participation can have a positive impact on health; however, physical challenges can be hindrances. During a preventive home visit a health professional (visitor) assesses different aspects of physical, mental and social health. However, there might be a challenge for the visitor to discover the interrelationship between physical factors that hinder social participation. There

Chronic pain 1–5 years after heart transplantation—A nationwide cross-sectional cohort study

Aim: To provide a multidimensional assessment of self-reported chronic pain 1–5 years after heart transplantation and its relationship with self-reported well-being, fatigue, recovery, self-efficacy and socio-economic factors and to explore differences between heart recipients and a cohort of lung recipients. Design: This multicentre, cross-sectional, cohort study is a part of the Swedish national

Better implant survival with modern ankle prosthetic designs : 1,226 total ankle prostheses followed for up to 20 years in the Swedish Ankle Registry

Background and purpose — We have previously reported on the prosthetic survival of total ankle replacements (TAR) in Sweden performed between 1993 and 2010. Few other reports have been published on 5- and 10-year survival rates. Furthermore, there is a lack of long-term outcome data on modern prosthetic designs. Therefore, we compared early and current prosthetic designs after a mean 7-year follow
