Butadiynyl-substituted h-benzeneCr(CO)3 complexes 3 are very efficiently prepared by a copper catalyzed coupling of the phenylacetylene complex 1 and bromo alkynes 2. The transmission of electronic effects through the butadiynyl bridge operates by resonance mechanisms as established by correlations between Hammett’s sp, sR and sP parameters. Most interestingly, however, is an unusual thermal be...

The market for mats and blankets made from natural fibers is a rapidly growing segment of the erosion control industry. In south Louisiana, bagasse is a local, readily available material with properties that make it suitable for erosion control products. In the framework of work towards diversifying the sugarcane industry, a prototype of a simple continuous device to produce erosion control mat...

Coordination compounds of some transition metal ions with 2-acetylpyridene-o-hydroxybenzoylhydrazone (APo-OHBH) were synthesized. Their structures have been characterised by elemental analyses, electrical conductance, magnetic moments (at 25 degrees C) and spectral (IR, UV, NMR) studies. The fast atom bombardment (FAB) method was used for obtaining mass spectra of the positive ion FAB studies o...

UNLABELLED Clinical and experimental study. Introduction. Of debatable etiology, Recurrent Aphthous Ulcerations (R.A.U), is most of the time considered an immunological deficiency. AIM The aim of this paper is to review the literature and clinical investigations regarding IgA-s, total proteins salivary concentration and basal salivary flow of patients with R.A.U. during activity and quiescenc...

The tremendous therapeutic potential of curcumin as a chemopreventive, antineoplastic and chemosensitizing agent has failed to progress towards clinical development and commercialization due to its unfavorable physicochemical properties, low aqueous solubility, chemical instability, and pharmacokinetics. The present contribution is focused on the feasibility of using PEGylated calixarene, in pa...

Roasting is among the most common methods of nut processing causing physical and chemical changes and ultimately increasing overall acceptance of the product. In this research, the effects of temperature (90, 120 ,and 150°C), time (20, 35 ,and 50 min) ,and roasting air velocity (0.5, 1.5 ,and 2.5 m/s) on gravimetrical properties of pistachio nuts and kernels including unit mass, true density, o...

Abstract Dry fractionated legume protein ingredients are gaining attention as alternatives to conventional solvent extracted proteins, being more resource efficient and often exhibiting novel functional properties. However, lack of knowledge about the relationship between composition functionality limit a wide-spread use dry-fractionated in applications. In this study, lentil fractions differen...
