Abstract: Using brown cotton varieties will help to solve certain existing
ecological problems which concern dying yarn and tissues. In
2005 8 lines of brown cotton were included in a preliminary
variety testing and in 2006 8 of these lines were included in a
competition variety trial. In 2005 12 other lines with naked
seeds and brown fiber were also included in a preliminary
testing. In the second year a new experiment was conducted
including 8 new lines in a preliminary variety testing. The
results obtained showed that the studied lines possessed high
breeding value. In terms of earliness and productivity some of
them were equal to the early and high yielding variety of white
cotton – Chipan-539. These lines are of great importance for
developing new cotton varieties with high economic and
ecological effect in spite of their shorter fiber and lint
percentage lower than the standard variety. Two lines No. 115
and No. 121 had commercial potential. Of the lines with brown
fiber and naked seeds No. 105 and No. 106 appeared to be very
valuable for cotton breeding programs because of the colouring
uniformity of brown fiber, as well as No. 98 which in fiber
length and lint percentage was equal to the standard variety,
and No. 101 for its longer fiber (by 1.5 mm over the standard).
New lines combining brown fiber, naked seeds and naturally early
leaf-fall were also obtained.

Abstract: An
assessment of the effect of climate change on Nestos delta (N.
Greece) was carry out by using Remote Sensing, water analysis
and GIS techniques. Comparing two satellite images of Nestos
delta which were captured with a seven years instance, we
observe the covering of a significant percentage of land (27 ha)
by the sea. Meanwhile the laboratory chemical analysis results
which were realised in 46 water samples from the swallow
underground aquifer verify the accelerating intrusion of sea
water into the land. The land use evanescence is caused by two
factors, firstly by a natural factor (climate change) and
secondly by a human factor (reduction of sediment supply to the
delta as a result of the construction upstream of two big earth
dams) and has as a result significant modification to what
regards the area and the shape of the Nestos delta. These two
aggravating factors act together and result to the saltwater
intrusion, to the salinazation of land, to economical losses of
160 million euro and threaten the subsistence of 16 adjacent
settlements, the agriculture land and the sustainability of
delta.

Abstract: Applying
some biomarkers in aquatic organisms as indicators of pollution
effect has been developed during the recent decades .Such
biomarkers represent the physiological state of organism and
ecological status of environment. In this connection, Bivalves
are one of the most interesting groups of marine organisms. The
mollusks have been known to naturally accumulate metals, to high
concentrations, in particularly in the digestive gland. The main
role in binding high toxic Cd belongs to MT as response followed
by cadmium exposure. But some of the mollusks have not been
revealed MT. So in scallop Mizuhopecten yessoensis have not been
found protein as MT.
The aim of current research is
identification and study of content of Cd-binding proteins of
digestive gland of different species of mollusks.
In adult mollusks from different familiars
were taken for experiment. In the cells of digestive gland
Mizuhopecten yessoensis (scallop, Pectinidae), Mytilus trossulus
(Mitilidae), Perondia venulosa (Tellinidae), Mercenaria
stimpsoni (Veneridae) were carried out comparative assessment of
Cd-binding proteins content both intact objects and under load
of cadmium.
The results have shown the peculiar feature
in distributing cadmium among cytosolic proteins studied
mollusks. And also, a new on this day, high-molecular Cd-binding
protein has been found to be involved in the binding of cadmium
in digestive gland M. yessoensis.

Abstract:
Legumes are an important component the
Mediterranean grasslands. In these areas plants are often
exposed to water deficit conditions during their life cycle due
to climatic conditions. The aim of this study was to assess the
impact of water stress in the reproductive traits of Medicago
disciformis. The
plants were
allowed to grow
in pots. Two irrigation treatments were applied: a) full
irrigation (at field capacity), and b) low irrigation (40% of
the field capacity.
Water stress was imposed in plants early spring.
Seeds were collected at the end of the growing season and seed
number, weight and moisture content were calculated. Standard
germination test and total seed viability were calculated.
Water deficit positively affected the seed yield but negatively
affected the thousand seed fresh weight and seed moisture
content. However, seed viability was high thereby expressing the
high adaptation of the species to the Mediterranean climatic
conditions.

Abstract:
“The Secular hayfields from Valea lui David” floristic reserve,
located at 16 km from the town of Iasi, has an area of 46.36 ha
and it has been in the custody of the “Anastasie Fatu” Botanical
Garden from Iasi, since 2006. Within the perimeter of the
reserve, field investigations revealed a rugged relief
displaying slope breaks, landslidings, and springs that render
the humidity and the salinity of the soil highly variable.
Vegetation distribution is patchy and comprises several
categories: xerophilous (Taraxaco serotinae -Festucetum
valesiacae ssas. festucetosum valesiacae and ssas. koelerietosum
macrantha, Jurineo arachnoideae-Stipetum lessingianae, Agropyro
pectinati-Stipetum capillatae, Artemisio austriacae-Poëtum
bulbosae, Taraxaco serotinae-Botriochloetum ischaemi,
Xero-Phragmitetum), nitrophilous (Sambucetum ebuli,
Sclerocloo-Polygonetum avicularis, Capsello-Descurainietum
sophiae, Onopordetum acanthi, Sclerantho-Trifolietum arvense,
Carduetum acanthoides), mesohygrophilous (Rorippo
austriacae-Agropyretum repentis), hygrophilous (Agrostio-Caricetum
distantis, Galio palustris-Caricetum ripariae, Phragmitetum
vulgaris), halophilous (Astero tripoli-Juncetum gerardii,
Puccinelietum limosae, Camphorosmetum annuae,
Staticeto-Artemisietum monogynae), and shrubby associations (Prunetum
tenellae, Pruno spinosae-Crataegetum). The studied zone shows a
remarkable floristic and phytosociological diversity in a
relatively small area and it is important for the conservation
of steppic vegetation, given that this type of landscape is one
of the most degraded of Europe.

Abstract:
The
structure of the industry, built during the last 50 years in
Bulgaria was and still is high energy consuming. “LUKOIL
NEFTOCHIM BOURGAS”AD is not an exception. The different units
have been built during different periods, with different
technologies, with a low level of heat integration and secondary
energy sources utilization. The efforts made in this direction
give an undoubted but a still insufficient result. The energy
index of Solomon E II for the last 5 years is shown on Figure 1.
This is a generally accepted key parameter, characterizing the
energy consumption of the refinery units during motor fuels
production (Fig.1).
Irrespective of the efforts for energy consumption reduction in
the ãîðèâíè units in the Thermal Power Station and the process
heaters, great amounts of liquid fuels and gas are being burnt
and will be burnt in the near future with considerable emissions
of pollutants – CO2, SO2, NOx,
CO, dust and soot to the atmosphere. At the end of 2001 the
official publication of the European Union – Official Journal
has published two directives of significant importance for the
Thermal Power Stations of the 15 (at that time) member
countries. These documents concern directly to a certain extent
the Republic of Bulgaria, as a future member of the European
Union.

Abstract:
The questions of changing
the habit of microorganisms under the influence of oil
extraction are considered. The technogenous eutrophication of
ecosystems is shown by experimental data and results of field
inspections. The operation of a petroleum deposit results in
formation of technogenous areas, which sources are oilfield
objects and flows of nature-technogenous substances. The
introducing of technogenous organics (petroleum) of various
quantity and changing the structure of reducers community caused
by this influence are characteristic. A prevailing component of
microbial community becomes hydrocarbon oxidizing (oil

Abstract:
The aim of
current research is the studying the influence of oxygen
deficiency on a state of antioxidant defence system of marine
mollusks Anadara broughtoni and the development of oxidative
stress (to ascertain the level of lipid peroxidation products).
Adult mollusks of Anadara broughtoni were put into the anoxia
state (24, 72, 168 h) with following reoxygenation (72 h). At
the end of experiments total oxyradical scavenging capacity (TOSC)
were determined in gills and digestive gland, we also observed
the content of low-molecular antioxidant – glutathione, and the
level of lipid peroxidation products (MDA). The results showed
that anoxia stimulates decreasing of TOSC in gills tissues with
a greater extent than in digestive gland. At the same time
changes in content of glutathione in mollusk tissues had diphase
character (increasing of content during 72 h and drastic
decreasing up to 168 h). It was marked that the antioxidant
defence has tended to recover during the reoxygenation
processes. Accumulation of MDA products was noticed along with
these changes. Thus the results of experiments have shown the
high lability of antioxidant defence system. It provides the
high resistance of Anadara broughtoni to such stress factor as
hypoxia.
