This paper presents the initial results of the “Minerva Project” obtained by means of two different 3D scanning techniques. The Minerva of Arezzo is a bronze statue (Archaeological Museum in Florence) currently under restoration. The “Minerva project” intends to show how 3D techniques can integrate standard diagnostic methods giving useful and powerful tools to the restorers. The main goal of t...
The adsorption removal of Triphenylmethane & Xanthene dyes onto a low-cost coal based adsorption (Charfines) and its efficiency in dye colour sorption was compared with activated carbon (F-400). Batch studies were performed and the results revealed that Charfines demonstrated on ability to adsorb the reactive Triphenylmethane & Xanthene dyes. The sorption interaction of reactive dye on to Charf...
The UASB reactor (35 C) was quite efficient for removal of bulk COD (52–74%) from the raw and diluted cultivation medium from the first separation process of baker’s yeasts (the average organic loading rates varied in the range 3.7–16 g COD/l/d). The aerobic-anoxic biofilter (19–23 8C) can be used for removal of remaining BOD and ammonia from anaerobic effluents; however, it had insufficient CO...
The UASB reactor (35 degrees C) was quite efficient for removal of bulk COD (52-74%) from simulated (on the basis of cultivation medium from the first separation process) general effluent of baker's yeast production (the average organic loading rates varied from 8.1 to 16 g COD/l/d). The aerobic-anoxic biofilter (19-23 degrees C) can be used for removal of remaining BOD and ammonia from anaerob...
In this paper a novel adaptive filtering scheme for impulsive noise removal in colour images is presented. The noise detection algorithm is based on the concept of aggregated distances assigned to the pixels belonging to the filtering window. The value of the difference between the accumulated distance assigned to the central sample and to the pixel with the lowest rank, serves as an indicator ...
humic substances (hS) constitute a large part of organic matter found in aquatic environment. the hS strongly interact with both inorganic and organic pollutants. Occurrence of the hS in groundwater accounts for many problems with treatment procedures. these natural components cause an increased intensity of water colour, affect its taste and odour, hinder removal of iron, manganese and other m...
The UASB reactor (35 degrees C) was quite efficient for removal of bulk COD (62-67%) even for such high strength and recalcitrant wastewater as the cultivation medium from the first separation process of baker'syeasts (the average organic loading rates varied from 3.7 to 10.3 g COD/l/d). The aerobic-anoxic biofilter (20 degrees C) can be used for removal of remaining BOD and ammonia from strong...
