Abstract: In this work are researched risky geomorphologic processes in
the mountain area
of Ograzhden and Maleshevo. There was used methodology of multifactor
analyzes
in integrated geo-information system and classic geomorphologic
methods.
Purpose of the research is to generate methodology of research
contemporary
exogenic processes and areas define of geomorphologic risk on the base
of
geo-information technology taking into account local influence of wide
spectrum
of natural and anthropogenic factors.

Abstract: The port Bourgas is a key-point on trans boarder Corridor 8, ensures direct access to the
Black Sea of Southern Italy ports. For these
reasons the Bourgas port is chosen as the pilot site. In this connection the
current water quality status of the Bourgas bay and the Bourgas port,
respectively according to the available information is evaluated. The
sampling
station and the parameters that are determined are given. The
generalized data
are tabulated and illustrated graphically where the variation of water
quality
parameter could be seen. Finally some conclusions are given. They could
be used
during the next stages of the project at establishment of a port
environmental
monitoring system.

VIBRIO CHOLERAE – БИОЛОГИЯ И ЕКОЛОГИЯ
И. Абрашев, Р. Енева, С. Енгибаров
Abstract.
Vibrio cholerae is part of the autochtonous bacterial flora
of marine, estuarine and
freshwater environments all over the world.
The strains belonging to О1 and О139 serotypes cause cholera epidemics. The strains of the rest serotypes are able to cause limited outbreaks of diseases with cholera-like
symptoms
in milder form, but also otitis, wound
infections as well as septicemia.
The species possesses a number of features that ensure its prolonged survival in aquatic environments,
and a
set of virulence factors that allow it to colonize the human intestine.
A general survey of the virulence and pathogenicity factors and their
relation
to the ecology of Vibrio cholerae are the subject of the
following review.

Abstract: The
paper deals with experimental studies and mathematical modeling of continuous
process of anaerobic digestion of chicken litter in laboratory scale.
Two types
of models have been developed: mass balance model and artificial neural
networks model. Comparative studies show that both of them have
appropriate dynamical
properties and may be useful for biogas production forecasting and
control.
Key words: anaerobic digestion, chicken
litters, mass balance
model, neural networks model.
