Polypropylene/ maleic anhydride /organic montmorillonite nanocomposites (PP/ MA/ Org-MMT) have been prepared via direct melt intercalation in an internal mixer. Maleic anhydride (MA) was used as a compatibilizer to improve the dispersability of the clay. The structures of nanocomposites have been characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Mechanical properties and thermal stability were determined by tensile analysis and thermogravimetric analysis (TGA), respectively.

This study introduced a method to produce a thermosensitive nanocomposite hydrogel (nCur-PG) containing curcumin nanoparticles (nCur) which can overcome the poor dissolution of curcumin. Regarding to the method, a thermo-reversible pluronic F127-grafted gelatin (PG) play a role as surfactant to disperse and protect nanocurcumin from aggregation. The synthetic PG was identified by 1H-NMR. The obtained results via Transmission Electron Microscopy (TEM) and Dynamic Light Scattering (DLS) indicated that the size of nCur was various in the range from 1.5 ± 0.5 to 128 ± 9.

The aim of this dissertation is to discover if there is relationship between applying Lessons Learned (LL) and project success in the context of project management. In addition it will investigate the factors affecting the collection and dissemination of LL to determine what role these play in inhibiting the successful use of LL. This paper was built around Project managers (PMs) in Ireland. From this research recommendations are made to improve the use of LL and to avoid the barriers that impede the successful implementation of LL.

Fourier transform infrared (FTIR) studies showed the changes in a relative intensity of stretching vibrations of the PANI and PANI-Ni films, in a band of 1480 and 1590 cm-1 , as well as those in a band of 1200 and 1350 cm-1 , and evidenced the conversion of quinoid form of PANI to bipolaron structure, and finally to the more delocalized polaronic sites during protonation. This also shows that nickel-nanoclusters play a role as a source supplying protons to promote the protonation, giving a change in population of quinoid and aromatic forms of PANI, and increasing a number of NH bond.

Feedback is an integral part of our lives. Try touching your fingertips with your eyes closed; you may not succeed the first time because you have broken a feedback loop that ordinarily “regulates” your motions. The regulatory role of feedback manifests itself in biological, mechanical, and electronic systems, allowing precise realization of “functions.” For example, an amplifier targeting a precise gain of 2.00 is designed much more easily with feedback than without.

To examine the role of the distal His42 residue in the catalytic mechanism of pea cytosolic ascorbate peroxidase, two site-directed variants were prepared in which His42 was replaced with alanine (H42A) or glutamic acid (H42E). Electronic spectra of the ferric derivatives of H42A and H42E (pH 7.0, l ¼ 0.10 M, 25.0 °C) revealed wavelength maxima [kmax (nm): 397, 509, % 540sh, 644 (H42A); 404, 516, % 538sh, 639 (H42E)] consistent with a predominantly fiveco-ordinate high-spin iron.

Mitochondrial DNA (mtDNA) deletion mutations accumulate with age in tissues of a variety of species. Although the relatively low calculated abundance of these deletion mutations in whole tissue homogenates led some investigators to suggest that these mutations do not have any physiological impact, their focal and segmental accumulation suggests that they can, and do, accumulate to levels sufficient to affect the metabolism of a tissue.

The role of the negative charge of the E139 side-chain of AnabaenaFerredoxin-NADP + reductase (FNR) in steering appropriate docking with its substrates ferredoxin, flavo-doxin and NADP + /H, that leads to efficient electron transfer (ET) is analysed by characterization of several E139 FNRmutants. Replacement of E139 affects the interaction with the different FNRsubstrates in very different ways.
