ASPECTS CONCERNING THE COMPOSITION OF SOME
BRONZE ROMAN COINS PATINA
The earlier roman bronze denominations, such as and sestertius, were
stroked in bronze (Cu Sn binary alloy). The coinage title decreases on the later
Roman Empire, silver denarius were finally replaced by the copper follies. The
X-ray diffraction analysis of such coins surface allows us to identify the rust
compounds. We found that on the bronze coins surface are developed mainly
copper oxides, hydroxides as well as tin oxide. We also reach a complex CuSn
hydroxide which gives a greenish yellow shade of the patina. The green hue of
patina is significant enhanced by the average of copper carbonate content also
found as a patina component. The copper foils feature only copper oxides and
hydroxides without carbonates. It proves that the investigated follies laid in a
more inert soil (e.g. quartz sand). The colour of patina is dark brown to shiny
black due to the refined mixture of copper oxides and hydroxide. Some quartz
traces were identified on the coins surfaces as residues of soil. The performed
analysis gives important data useful for modern fake’s identification.

resources for future generations have led to increased efforts to find alternative
energy sources and for improve the energy efficiency. The „green jobs” should

Once we become adults, no one expected to become more intelligent,
even our mental capacities can be used more effectively in the experience. This
is true for emotional intelligence. The way we communicate with others and
how we communicate with ourselves ultimately determines our quality of life.
The more we know each other better and understand better, the wiser
decisions we take and we will get better results. We can and we must
continually improve our emotional skills, to do everything possible to become a

COMMUNICATION IN LEADERSHIP –
EFFICIENCY AND PRINCIPLES
Communication is crucial in the effectiveness of a leader. Brian Tracy
is very categorically stating that „if you cannot communicate, cannot be leader.”
But effective communication is based on trust, that leader must know how to
win from subordinates. Leaders know how to listen and to become a good
leader, able to communicate effectively, you must know to listen to the other.
That’s because everyone always feels the need to feel important and valuable.
Especially, a subordinate leader will consider actions that will help raise the
self; it will make them enjoy longer, and, consequently, make it more efficient
gear organization operating.
