Human factor policy testing in the sequencing of manual mixed model assembly lines

2004

In this paper the human resource management in manual mixed model assembly U-lines is considered. The objective is to minimise the total conveyor stoppage time to achieve the full efficiency of the line. A model, that includes effects of the human resource, was developed in order to evaluate human factor policies impact on the optimal solution of this line sequencing problem. Different human resource management policies are introduced to cope with the particular layout of the proposed line. Several examples have been proposed to investigate the effects of line dimensions on the proposed management policies. The examples have been solved through a genetic algorithm. The obtained results conf…

Protection of the right to freedom of assembly and association under ECHR: compliance difficulties in Azerbaijan

2018

The protection of the right to freedom of peaceful assembly and association under the ECHR and compliance difficulties in Azerbaijan, regarding these rights are discussed in this master thesis. The protection of the right to freedom of peaceful assembly and association is one of the critical elements for the development of democracy, and these rights are protected by international documents such as the European Convention for the Protection of Human Rights and Fundamental Freedoms (hereinafter referred as the European Convention on Human Rights or the ECHR). Furthermore, the protection of these rights at national level must be compatible with the standards of the Council of Europe. The impo…

Polymerized Ionic Liquids with Polythiophene Backbones: Self-Assembly, Thermal Properties, and Ion Conduction

2018

Single ion conductors, based on polymerized ionic liquids (PILs) with a polythiophene backbone bearing imidazolium salts with butyl, hexyl, octyl, and decyl side groups and six different counterani...

Solvent-Dependent Self-Assembly of an Oxalato-Based Three-Dimensional Magnet Exhibiting a Novel Architecture.

2016

The old but evergreen family of bimetallic oxalates still offers innovative and interesting results. When (Me4N)3[Cr(ox)3]·3H2O is reacted with Mn(II) ions in a nonaqueous solvent, a novel three-dimensional magnet of the formula [N(CH3)4]6[Mn3Cr4(ox)12]·6CH3OH is obtained instead of the one-dimensional compound obtained in water. This new material exhibits an unprecedented stoichiometry with a binodal (3,4) net topology and the highest critical temperature (TC = 7 K) observed so far in a manganese-chromium oxalate based magnet.

Hybrid assemblies based on a gadolinium-containing polyoxometalate and a cationic polymer with spermine side chains for enhanced MRI contrast agents.

2013

Supramolecular assembly: Spherical and stable hybrid assemblies based on a cationic polymer with spermine side chains and an anionic Gd(3+)-containing polyoxometalate cluster (GdW) are prepared by electrostatic interaction. The T1-weighted MRI performance of GdW is enhanced about three times in the assemblies; meanwhile, the assemblies show good biocompatibility, which enables them to be promising candidates for MRI contrast agents.

Emerging dynamics in surfactant-based liquid mixtures: octanoic acid/bis(2-ethylhexyl) amine systems.

2012

This work focuses on the dynamic phenomena emerging in self-assembled transient intermolecular networks formed when two different surfactants are mixed. In particular, the relaxation processes in liquid mixtures composed by bis(2-ethylhexyl)amine (BEEA) and octanoic acid (OA) in the whole composition range has been investigated by dielectric spectroscopy and Brillouin spectroscopy. A thorough analysis of all the experimental data consistently suggests that, mainly driven by acid-base interactions arising when the two surfactants are mixed, supra-molecular aggregates formation causes the slowing down of molecular dynamics. This, in turn, reflects to longer-range relaxations. These changes ha…

IL-17A induces chromatin remodeling promoting IL-8 release in bronchial epithelial cells: Effect of Tiotropium

2016

Abstract Aims IL-17A plays a key role in the persistence of airway inflammation, oxidative stress, and reduction of steroid-sensitivity in COPD. We studied the effect of IL-17A on chromatin remodeling and IL-8 production. Main methods We measured the levels of IL-8 and IL-17A in induced sputum supernatants (ISS) from healthy controls (HCs), healthy smokers (HSs), and COPD patients by enzyme-linked immunosorbent assay (ELISA). A human bronchial epithelial cell line (16HBE) was stimulated with ISS from HCs, HSs, or COPD subjects. IL-8 was evaluated in 16HBE by Western blot and real-time polymerase chain reaction (PCR). Histone deacetylase 2 (HDAC2), acetyl histone H3 (Ac-His H3) (k9) and inhi…
