Inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. The present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (PEC) based microparticles containing antibacterials for the treatment of lung infections.Chitosan polyelectrolyte complex...

Sorption behaviour of radiata pine has been investigated by weighing small specimens continuously during isothermal step changes in relative humidity. The use of wood specimens shorter in the longitudinal direction than the average tracheid length of radiata pine ensures that all tracheids in a specimen are exposed, reducing the effect of wood structure on bound water transport. The small size ...

−− The results obtained in the analysis of the thermal behaviour of a forest biomass fluidized bed dryer with mechanical agitation, are reported. The study is carried out in a pilot size experimental equipment in batch operation. By means of Taguchi’s techniques the specific consumption of energy and the rates of evaporation of water and production of dry biomass are analyzed based on the contr...

The behaviour of different cellulosic fibres during acid hydrolysis has been investigated and the levelling-off degree of polymerisation (LODP) has been determined. The study included a bleached kraft pulp (both never-dried and once-dried) and two dissolving pulps (once-dried). Additionally, cotton cellulose from new cotton sheets and sheets discarded after long-time use was studied. Experiment...

We have studied the rheological behaviour of concentrated maltodextrins varying in dextrose equivalence value (DE) over a range temperatures (?70 °C) and concentrations (?62% (w/w) solids) using small amplitude oscillatory experiments. Rheological data could be mapped onto master curves for storage loss modulus as described with model transient or entangled polymeric networks. Maltodextrins DE5...

The paper presents some of the advanced experimental techniques and apparatuses that have been developed by the authors for testing the hydromechanical behaviour of shales. A methodology established for the analysis of the water retention behaviour in non-isochoric conditions is introduced; the method allows for the determination of the main drying and wetting paths in addition to the volume ch...

Valorisation of fruit and vegetable wastes by transforming residues discards into functional powdered ingredients has gained interest in recent years. Moreover, fermentation been recalled as an ancient technology available to increase the nutritional value foods. In present work, impact pretreatments (disruption fermentation) on drying kinetics properties broccoli stems was studied. Broccoli fe...
