Ford of Europe’s Product Sustainability Index (PSI) is a sustainability management tool directly used by engineering, i.e. not by sustainability or life cycle experts. PSI is looking at eight indicators reflecting environmental (Life Cycle Global Warming Potential, Life Cycle Air Quality Potential, Sustainable Materials, Restricted Substances, Drive-by-Exterior-Noise), social (Mobility Capabili...

in this paper, the finite element analysis of stability problem of vehicle composite drive shafts subjected to torsional loading is studied. first, using the minimum total potential energy principle, the governing equations are derived and then they are solved by finite element method. the initial geometrical imperfection which is usually in the form of radial displacement, is taken into consid...

Prevention of cell spreading or disruption of actin filaments inhibits growth factor stimulated cell cycle re-entry from quiescence, mainly because of a failure to induce cyclin D expression. Ectopic cyclin D expression overrules anchorage-dependency, suggesting that cell spreading per se is not required as long as cyclin D is otherwise induced. We investigated whether cyclin D expression in ce...

OBJECTIVES The aim of patient information is to involve patients in their condition and their treatment. The literature states that good information can improve medical outcomes, reduce patient anxiety and that patients want access to it. We wanted to calculate the provision of written patient information to ENT day-case patients, measure information recall and patient satisfaction. DESIGN A ...

From yeast to humans, cell cycle progression and cell division are driven by the sequential activation of a group of serine-threonine kinases called cyclin-dependent kinases (Cdks). Multiple Cdks control the cell cycle in mammals and have been long considered essential for normal proliferation, development and homeostasis. The importance of the Cdk-cyclin complexes in cell proliferation is unde...

In this study we investigated how the networks mediating respiratory and locomotor drives to lumbar motoneurons interact and how this interaction is modulated in relation to periodic variations in blood pressure (Mayer waves). Seven decerebrate cats, under neuromuscular blockade, were used to study central respiratory drive potentials (CRDPs, usually enhanced by added CO2) and spontaneously occ...

Introduction and Aim: In light of the ongoing pandemic Covid -19 vaccination drive, our study intended to observe association reported side effects vaccine menstrual cycle. There is no research done about covid on Materials Methods: A cross-sectional online questionnaire-based was conducted females aged between 18-45 years who had received at least one dose vaccine. The google form containing q...

A conformation space kinetic model is constructed to drive the deformation cycle of a three-sphere swimmer to achieve propulsion at low Reynolds number. We analyze the effect of an external load on the performance of this kinetic swimmer and show that it depends sensitively on where the force is exerted, so that there is no general force-velocity relation. We discuss how the conformational cycl...

Hybrid electric vehicles, plug-in hybrid electric vehicles, and battery electric vehicles offer the potential to reduce both oil imports and greenhouse gases, as well as to offer a financial benefit to the driver. However, assessing these potential benefits is complicated by several factors, including the driving habits of the operator. We focus on driver aggression, i.e., the level of accelera...
