AB  - PbTe single crystals, doped with B, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and room temperature. The experimental spectra were numerically analyzed, and optical parameters were calculated. Local impurity modes of boron were observed at about 150 and 240 cm(-1). For all samples, after FIR measurements, the content of boron was measured using inductively coupled plasma atomic emission spectrometry. Optical mobility of free carriers was calculated and it was the highest for the sample with only 0.014 at.% of boron in PbTe. A negative photoconductivity effect at 130 K for PbTe + B was also observed.

AB  - Specimens of the freshwater snail Holandriana holandrii affected by different levels of contamination were collected from 3 sites within the Bosna River Basin, i.e. Visoko, Doboj, and Modrica. The activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR), and glutathione-S-transferase (GST) were investigated in order to understand their variation with respect to the pollution status of the sampling locations. The results revealed a significant increase in CAT, GPx, and GST activities in the snails collected from Modrica, suggesting that the animals at this location are exposed to a higher level of oxidative stress as compared to those from Visoko and Doboj. On the other hand, increased SOD activity measured in specimens from Visoko was indicative of the presence of increased levels of superoxide anion radical. No snails from any location were significantly exposed to organic pollution, since its concentration in the whole body homogenates was below the limit of detection. Our findings show that changes in antioxidant enzymes and GST activity can be used as parameters in environmental monitoring programs.

AB  - Far infrared reflectivity spectra of polycrystalline In1-xGaxSb were measured and numerically analyzed using the classical dispersion formula and also a fitting procedure based on the modified plasmon-phonon interaction model in the temperature range from 10 K to 300 K. Optical parameters were calculated and discussed. A local mode belonging to the GaSb rich end and two-mode behavior were observed at low temperatures.

AB  - A single crystal Bi0.9Sb0.1 ingot was synthesized using the Bridgman technique. Thermal diffusivity and electronic transport properties of single crystal cleaved plates (001) were determined from PA photoacoustic phase and amplitude spectra obtained using the photoacoustic method with a transmission detection configuration. Both the PA phase and amplitude were measured versus the modulation frequency and numerically analyzed. EDS analyses done to determine chemical composition of the studied samples as well as to check sample homogeneity. Hall effect measurements data were used for the photoacustic measurements.
