ABSTRACT
The novel crystalline alloys CdTe-CuInTe2 were synthesized. The photoinduced spectral changes of the anharmonic phonon modes were explored by cw CO2 laser at power about 2 kW in the vicinity of the 1650 cm(-1) mode. The changes of the intensities for principal phonon modes were found. These modes were assigned both to harmonic as well as anharmonic modes. All the measurements are studied after the Ir illumination. The performed quantum chemical calculations with application of the norm-conserving pseudopotential method and Green functions allow to identify the origin of the content dependent anharmonic phonon modes. Some correlation between the intensities of the corresponding phonon modes at about 1600-1700 cm(-1) and the corresponding IR induced changes were found.

A case of extreme basal cell carcinoma affecting eyelids region in a 66-year old man is presented. Long time duration, large destruction of the face tissues and histopathological type of metatypic basal cell carcinoma (bcc) eliminated any way of therapy (surgery, radiotherapy, chemotherapy). We present this case because bcc as localy invasive tumor with low growth, diagnosed and treated at early stage can lead to complete recovery.
