Experimental and numerical assessment of the work of fracture in injection-moulded low-density polyethylene

The fracture mechanics properties of injection-moulded low-density polyethylene (LDPE) sheets were investigated both experimentally and numerically. The total work of fracture was determined experimentally, by means of fracture mechanics testing of sheets of injection-moulded LDPE with side cracks of different lengths. A multi-specimen method, proposed by Kim and Joe (1987), was employed. The tota

Experimenting with a circular business model: Lessons from eight cases

Experimentation is an important capability in the transition to a sustainable business. The aim of business experimentation is to learn and improve business model innovation activities with limited risks and resources through continuous and collective learning with stakeholders. Through action research we worked with eight case companies on a pathway to becoming a sustainable business. We focused

Business Model Experimentation for Circularity: Driving sustainability in a large international clothing retailer

Business model experimentation for sustainability is an intentional and systematic approach to identify, test and learn about value creation strategies that could be adopted by a business in response to current unsustainable trajectories. For businesses such as large clothing retailers the need to alter course is acute as pressure builds from economic, environmental and social angles. The circular

Point of no return for improvement of cartilage quality indicated by dGEMRIC before and after weight loss in patients with knee osteoarthritis : a cohort study

Background: It has been demonstrated that weight loss improves symptoms in obese subjects with knee osteoarthritis (KOA). A parallel change in cartilage morphology remains to be demonstrated. Purpose: To demonstrate a parallel change in cartilage morphology. Material and Methods: Obese patients with KOA were examined before and after weight loss over 16 weeks. Target knee joints were radiographica

Do not forget the parents—Parents' concerns during transition to adult care for adolescents with congenital heart disease

Background: Growing up with congenital heart disease (CHD) often means transfer to adult care and lifelong medical follow-up. An optimal transition process usually involves a multipart collaboration between the patient, their parents and other family members, and the healthcare providers. Taking an active role while knowing when it is time to step aside can be difficult for all the concerned parti

Effect of oxygen therapy on chest pain in patients with ST elevation myocardial infarction : results from the randomized SOCCER trial

Objective. Oxygen (O2) have been a cornerstone in the treatment of acute myocardial infarction. Studies have been inconclusive regarding the cardiovascular and analgesic effects of oxygen in these patients. In the SOCCER trial, we compared the effects of oxygen treatment versus room air in patients with ST-elevation myocardial infarction (STEMI). There was no difference in myocardial salvage index

Analysis of uv-visible fluorescence following inner-shell excitation of [Formula Presented] molecules

Light emission induced by inner-shell excitation of [Formula Presented] molecules has been investigated in the wavelength region [Formula Presented] Synchrotron radiation from the SuperACO storage ring in Orsay (France) has been used for the photoexcitation and a high-resolution secondary monochromator [Formula Presented] for the spectral analysis of the fluorescence light. Vibrationally resolved

Vitamin K: A potential Liver Cancer treatment way

A review on different vitamin K1-3 effects on hepatocellular cancer and their tumour cell biology mechanism indicate possible synergistic treatment strategies. Monitoring of dysfunctional carboxylation of the vitamin K dependent coagulation factor II, with the commercial ELISA test PIVKA-II has been used as a hepatocellular cancer marker. Its relevance is also reviewed. Currently the PIVKA-II test

Coagulation during elective neurosurgery with hydroxyethyl starch fluid therapy : an observational study with thromboelastometry, fibrinogen and factor XIII

BACKGROUND: Several studies have described hypercoagulability in neurosurgery with craniotomy for brain tumor resection. In this study, hydroxyethyl starch (HES) 130/0.42 was used for hemodynamic stabilization and initial blood loss replacement. HES can induce coagulopathy with thromboelastographic signs of decreased clot strength. The aim of this study was to prospectively describe perioperative

Factors associated with high physical exertion during manual lifting : Cross-sectional study among 200 blue-collar workers

BACKGROUND: High physical exertion during work is a risk factor for back pain and long-term sickness absence.OBJECTIVE: To investigate which factors are associated with physical exertion during manual lifting.METHODS: From 14 workplaces across Denmark, 200 blue-collar workers reported perceived physical exertion (Borg-CR10) during manual lifting from floor to table height of 5, 10, 20 and 30 kg at

Allele-selective RUNX1 binding regulates P1 blood group status by transcriptional control of A4GALT

P1 and Pk are glycosphingolipid antigens synthesized by the A4GALT-encoded α1,4-galactosyltransferase, using paragloboside and lactosylceramide as acceptor substrates, respectively. In addition to the compatibility aspects of these histo-blood group molecules, both constitute receptors for multiple microbes and toxins. Presence or absence of P1 antigen on erythrocytes determines the common P1 (P1+

Agonistic targeting of TLR1/TLR2 induces p38 MAPK-dependent apoptosis and NFκB-dependent differentiation of AML cells

Acute myeloid leukemia (AML) is associated with poor survival, and there is a strong need to identify disease vulnerabilities that might reveal new treatment opportunities. Here, we found that Toll-like receptor 1 (TLR1) and TLR2 are upregulated on primary AML CD34+CD38-cells relative to corresponding normal bone marrow cells. Activating the TLR1/TLR2 complex by the agonist Pam3CSK4 inMLL-AF9-driv

Identification and characterization of candidate therapeutic targets in acute myeloid leukemia

Acute myeloid leukemia (AML) is a fatal disease that is characterized by a rapid expansion of myeloid leukemic blasts with impaired differentiation that accumulate in the bone marrow. The prognosis for AML is generally poor, with a five-year overall survival of around 20% in patients over 60 years old. Current AML treatment strategies, including chemotherapy and hemapoietic stem cell trasplantatio

Eigenvalue-based time delay estimation of repetitive biomedical signals

The time delay estimation problem associated with an ensemble of misaligned, repetitive signals is revisited. Each observed signal is assumed to be composed of an unknown, deterministic signal corrupted by Gaussian, white noise. This paper shows that maximum likelihood (ML) time delay estimation can be viewed as the maximization of an eigenvalue ratio, where the eigenvalues are obtained from the e

Fisheries management under nutrient influence : Cod fishery in the Western Baltic Sea

A fisheries management model that identifies the economic optimal management of fisheries under the influence of nutrients is presented. The model starts from the idea that growth in fish biomass increases with increasing availability of nutrients owing to higher food availability up to a peak, after which growth falls due to eutrophication. The model is applied to Swedish and Danish cod fisheries
