A criterion for systematization of organic compounds is described. Organic compounds (estimated to 16-20 millions) are of three types: (A) symmetric (especially meso and C2 symmetric), (B) possible symmetry generators, i.e. compounds possessing a rea

It is believed that the place called Bermuda triangle is able to hide of human seeing objects entered its area. A Bermuda triangle in chemistry is able to hide (mask) atoms or planar molecular fragments cut by their mirror plane of symmetry, not of h

The present work is focused on thermoanalyt- ical investigations as thermogravimetric analysis (TG) and derivative thermal analysis (DTG), applied for the char- acterization of some samples collected from archaeological sites (Brasov and Trofeum Trai

A new theoretical model of an undulator for free electron lasers is presented. The current undulator structure is a series of hypocicloidal wires. The magnetic field components for each wire present a 120 degree symmetry (for a model with 3 branches)

Photodynamic therapy (PDT) of cancer has been known for over twenty years and is based on the dye-sensitized photooxidation of different biological targets in the tumoral tissue yielding to a photochemically induced cell's death via apoptotic pathway

In this paper the applications of holographic interferometry to ionizing radiation dosimetry are presented. The determination of the accurate value of dose delivered by an ionizing radiation source (released energy per mass unit) is a complex problem
