Comparing acquisition and operation life cycle costs of powder metallurgy and conventional wrought steel gear manufacturing techniques
The automotive industry has striven for fuel economy and resource efficiency through the deployment of powder metallurgy (PM) manufacturing processes for few decades. However, PM technology for transmission gears is currently only used at a small scale within the automotive industry. This is mainly due to: its shortcomings in material properties and performance gaps for final parts; lack of advanc

Simulation of nanometric cutting using molecular dynamics
The aim of this work is to perform molecular dynamic simulations of nanometric cutting on single crystal copper with a diamond tool in orderto investigate the dependence of crystallographic orientation and cutting speeds on the cutting forces, machined surface and temperature. It wasfound that the temperature in the substrate, locally and globally, increased for increasing velocity. A higher degre
Determining process parameters for successful material reclamation of lead-free brass chips using hot forging operations: Lubrication
When small and hollow components are being manufactured, it is not uncommon that a majority of the workpiece material is removed by machining. A demand for parts made with lead-free brass alloys can potentially increase the manufacturing cost and therefore it is necessary to investigate ways to increase the material utilization. As part of a more resource efficient production, a method for reusing

Multi-objective testing of different brass alloy components for DFM
This paper investigates the differences of leaded and low-lead brasses in terms of mechanical and thermal properties, machinability and product strength using physical testing and simulations. The information can be used in companies for Design for Manufacturability (DFM) while designing processes for lead free brass. The novelty of this research is to combine data from different testing methods t
Functional recovery of the germ line following splicing collapse
Splicing introns from precursor-messenger RNA (pre-mRNA) transcripts is essential for translating functional proteins. Here, we report that the previously uncharacterized Caenorhabditis elegans protein MOG-7 acts as a pre-mRNA splicing factor. Depleting MOG-7 from the C. elegans germ line causes intron retention in most germline-expressed genes, impeding the germ cell cycle, and causing defects in
Syndecan receptors : pericellular regulators in development and inflammatory disease
The syndecans are the major family of transmembrane proteoglycans,usually bearing multiple heparan sulfate chains. They are present onvirtually all nucleated cells of vertebrates and are also present in invertebrates, indicative of a long evolutionary history. Genetic models in bothvertebrates and invertebrates have shown that syndecans link to the actincytoskeleton and can fine-tune cell adhesion
Analytical and Experimental Determination of the Ra Surface Roughness during Turning
In this article an analytical equation for calculating the theoretical arithmetic mean surface roughness, Ra, in the case of turning using a tool with a circular nose radius is presented. The deviation that often occurs between the expected and the obtained surface roughness during these machining operations is investigated. Influence of the minimum chip thickness is discussed especially in regard
Syndecans in Inflammation at a Glance
Syndecans are transmembrane proteoglycans with heparan and chondroitin sulfate chains attached to their extracellular domain. Like many proteoglycans, they interact with a large number of ligands, such as growth factors, adhesion receptors, soluble small molecules, proteinases, and other extracellular matrix proteins to initiate downstream signaling pathways. Syndecans play a major role in inflamm
Glycan Mimetics from Natural Products : New Therapeutic Opportunities for Neurodegenerative Disease
Neurodegenerative diseases (NDs) affect millions of people worldwide. Characterized by the functional loss and death of neurons, NDs lead to symptoms (dementia and seizures) that affect the daily lives of patients. In spite of extensive research into NDs, the number of approved drugs for their treatment remains limited. There is therefore an urgent need to develop new approaches for the preve
