Powstające w gospodarstwach domowych odpady są coraz bardziej niebezpieczne dla środowiska. Zawierają one, poza resztkami pokarmu, papieru i tworzyw sztucznych, także zużyte oleje silnikowe i smarowe, zepsute świetlówki, baterie, termometry rtęciowe, przeterminowane lekarstwa, resztki farb, lakierów i rozpuszczalników oraz przeterminowane środki ochrony roślin i opakowania po nich.

The main problem hindering proper analysis and documentation of archaeological and historical textiles is the lack of co-operation between scientists dealing with different aspects of these objects – archaeological, artistic, historical and technological. The last one includes the examining of manufacturing methods and analysis of the raw material and dyes used by chemical and physicochemical analysis methods, which is fundamental for proper identification of the object,as well a sits originand dating.The methods include:SEM,ICP, ATR/FTIR and AAS for determination of the raw material and other components of the object, the archaeological environment, analysis of the biodeterioration of archaeological textiles, as well as HPLC for analysis of the colour. This paper presents the methods and exemplary results of research conducted by the authors at the Technical University of Lodz, involving the analysing of archaeological textiles from the area of Poland and historical textiles from the collections of Polish museums.

Głównym problem w analizie i dokumentacji tekstyliów zabytkowych i archeologicznych jest brak współpracy pomiędzy naukowcami zajmującymi się różnymi aspektami tych obiektów archeologicznym, artystycznym, historycznym i technologicznym. Ten ostatni obejmuje badanie metod wytwarzania oraz surowca i barwników za pomocą metod analizy chemicznej i fizykochemicznej, stanowiąc podstawę właściwej identyfikacji obiektu, jego pochodzenia i datowania. Metody obejmują SEM, ICP, ATR/FTIR i AAS w celu identyfikacji surowca i innych komponentów tekstyliów oraz środowiska archeologicznego, a także w badaniach nad biodeterioracją tekstyliów, oraz HPLC w celu identyfikacji koloru. Praca prezentuje te metody oraz przykładowe wyniki badań prowadzonych przez autorów na Politechnice Łódzkiej nad tekstyliami archeologicznymi z obszarów Polski oraz zabytkami tekstylnymi z kolekcji polskich muzeów.

Resistance causes of moulds to N,N-bis(3-aminopropyl)dodecylamine (APDA) for selected species of Aspergillus niger and Aspergillus flavus was examined. Control (sensitive) strains and resistant strains, cultured at 0.05% triamine, were used in the experiments. The non-resistant strains did not have growth capacity in this amount of ADPA while the resistant strains were characterised by a smaller biomass increase. Individual stages of the development of the mycelium occurred later than those in the control samples. The participation of the cell wall in the mycelium biomass of the resistant strains was higher by 7.5%. The glucan content in the wall dry mass was lower by 11% than that in the sensitive strains. A 41% increase in the lipid content was recorded in the cell wall of resistant Aspergillus flavus. A 21 % protein increase occurred in the wall of Aspergillus niger comparing to the control strain. Infrared spectrophotometry analysis of the cell wall did not reveal the presence of triamine. Most absorption bands disappeared in the wall of Aspergillus flavus while no additional absorption bands were registered in Aspergillus niger, some bands were only stronger than those in the control sample. The resistant strains were characterised by a smaller ergosterol content, the main constituent of cell membranes. Spectrophotometry analysis of the mycelium did not reveal significant qualitative changes; only quantitative changes were observed. It was noticed that the resistance reaction did not occur with the same intensity in both species studied. The resistant strain of Aspergillus niger was characterised by a slightly more intensive absorption within its entire spectrum range in comparison to control strain. In case of Aspergillus flavus the absorption was higher for control strain.

In the paper, effort was made to determine the spreading kinetics of binding liquid supplied to fine granular mass in a cylindrical apparatus and to find its relationship with the granulation process. At predetermined intervals during the wetting process the indicator (ethylene glycol) was added in a form of Dirac impulses and then the migration of liquid within granular mass was determined on the basis of the indicator content in a sample measured fraction. The measurement method was based on the extraction of indicator from a dried fraction of granulated material (silica flour) using CC14 and then applying the FTIR spectro-scopy.
