A steel alloy DP590 is commonly used for automobile applications because of its outstanding mechanical characteristics. One crucial limitation this forming that it has limited malleability and ductility. In study, we compared the experimental limit diagram (FLD) at RT 800°C using stretching. An experiment with a strain rate 0.01/s carried out samples cut in four different directions (0°,30°,60°...

Up to now a large number of models have been developed to measure or predict the damage in equipments. Some of these models have been implemented in ABAQUS software. To implement damage parameters in the software, it is necessary to perform complex and expensive practical tests. One of these damage models is Forming Limit Diagram (FLD).The purpose of this research is deriving required parameter...

The SELDI technology is a technique that measures the content of different proteins in blood samples from patients. Many research groups have shown that there appears to exist a relation between the concentrations of speci c proteins and cancer disease. The output from the SELDI system is a result of mass-spectrometry and is a spectrum containing the concentrations of thousands of separate prot...

Rapid wound-healing is crucial in protecting potato tubers from infection and dehydration. Wound-induced suberization and the accumulation of hydrophobic barriers to reduce water vapour conductance/loss are principal protective wound-healing processes. However, little is known about the cognate mechanisms that effect or regulate these processes. The objective of this research was to determine t...

As part of the certification campaign of three candidate reference materials for the determination of aflatoxin M1 (AfM1) in whole milk powders, homogeneity, short- and long-term stability tests of naturally contaminated milk powders have been performed. The homogeneity of two AfM1-contaminated milk powders was studied by taking samples at regular intervals of the filling sequences and analysin...

The cyanobacterial neurotoxin β-N-methylamino-L-alanine (BMAA) has been considered a serious health threat because of its putative role in multiple neurodegenerative diseases. First reports on BMAA concentrations in cyanobacteria were alarming: nearly all cyanobacteria were assumed to contain high BMAA concentrations, implying ubiquitous exposure. Recent studies however question this presence o...

Lecithin:cholesterol acyltransferase (LCAT) deficiency syndromes represent a group of rare genetic disorders of HDL metabolism that have been the subject of a large number of clinical, biochemical, and genetic studies. Of special interest are patients with LCAT-related disorders with severe HDL deficiency and the apparent absence of premature atherosclerosis. This finding is inconsistent with t...

BACKGROUND Fatty liver disease (FLD) is commonly associated with insulin resistance and obesity, but interestingly it is also observed at low insulin states, such as prolonged fasting. Thus, we asked whether insulin is an independent modulator of hepatic lipid accumulation. METHODS/PRINCIPAL FINDINGS In mice we induced, hypo- and hyperinsulinemia associated FLD by diet induced obesity and str...
