Zróżnicowanie fitocenotyczne biochor łąk w ramach programu rolnośrodowiskowego
PHYTOCOENOTIC DIFFERENTIATION OF MEADOW BIOCHORES UNDER AGRI–ENVIRONMENT SCHEME
Mapping
of plant communities biochores was carried out using the GPS receiver
on meadows of the Bydgoszcz Channel Valley in 2006–2008. Meadows were
with agri–environmental scheme (AES) or without. A total of 32 plant
communities were encountered on areas with AES and 23 outside. The
average number of communities and their surfaces were similar. Ostericum
palustre patches were only found on surfaces were the mowing time was
delayed on purpose as a rule of the AES.
Key words: agri–environment scheme, biochores, meadow, biodiversity, Bydgoszcz Channel Valley, Ostericum palustre

Zróżnicowanie florystyczne zbiorowisk nieużytkowanych łąk z rzędu Arrhenatheretalia na Pogórzu Przemyskim
FLORISTIC DIVERSITY OF UNUSED MEADOW COMMUNITIES OF THE ARRHENATHERETALIA ORDER IN PRZEMYSKIE FOOTHILLS
Four
plant communities are described in this study: Poa pratensis–Festuca
rubra, with Festuca rubra, with Agrostis capillarys, and with
Anthoxanthum odoratum, occurring on unused meadows and fields of
Przemyskie Foothills (SE Poland) in the context of selected ecological
factors, calculated with laboratory and phytoindication method by
Ellenberg. The communities were identified on the basis of 222
phytosociological releves made in 2006–2010. Species richness and S–W
biodiversity index were taken into consideration. The distinguished
communities occurred on mesic mineral and acidic soils with low
phosphorus, intermediate nitrogen and potassium, and high magnesium
contents. Most commonly they developed on insolated, intermediately warm
sites of south and western slopes. The highest average species richness
and S–W H’ values had communities with Agrostis capillaris, and the
lowest with Anthoxanthum odoratum. Except for the dominating species,
differences in floristic compositions were slight. Meadow species of the
Arrhenatheretalia order and Molinio–Arrhenatheretea class had a
substantial share in the floristic composition. There was a conspicuous
occurrence of numerous ruderal and segetal species, particularly in the
Agrostis capillaris community, which indicates the origin of
field–grasslands. The share of trees and shrubs was the highest in the
community with Anthoxanthum odoratum, while their cover in the community
with Agrostis capillaris. Protected and rare species, such as
Platanthera bifolia, Centaurium erythraea, Dianthus deltoides, Polygala
vulgaris, and Cirsium decussatum, most commonly occurred in the
community with Agrostis capillaris.
Key words: plant community,
unused meadows, fallowed fields, origin of field–grasslands,

Zastosowanie metod numerycznych do oceny wpływu energetycznego wykorzystania paliw na stan powietrza atmosferycznego
APLLICATION OF NUMERICAL METHODS TO INFLUENCE EVALUATION OF ENERGETICAL FUELS USING ON ATMOSPHERIC AIR CONDITION
In
this article showed the possibilities of prediction and combustion
products decrease, in particular NOx, during co–combustion process of
traditional and renewable (biofuels) fuels with numerical modelling
using. The primary fuel’s was natural gas. Biofuels introduced to
combustion process as reburning fuels. The following biofules make
subject to analysis, namely: a straw, a hay, a sawmill wastes, an
energetic willow, a rape oil and synthetic biogas. The conventional
fuel’s was diesel oil. The chemistry of the combustion process was
modelled using the software CHEMKIN. Numerical computations were
performed for the experimental chamber. Then was executed the
verification on basis of experimental data results.
Key words: combustion, reburning, biofuels, numerical modeling, CHEMKIN

Analiza morfologiczna wybranych ekotypów Lotus corniculatus L. z kolekcji Instytutu Hodowli i Aklimatyzacji Roślin w Bydgoszczy
MORPHOLOGICAL
ANALYSIS OF CHOSEN ECOTYPES LOTUS CORNICULATUS L. FROM THE COLLECTION
OF THE PLANT BREEDING AND ACCLIMATIZATION INSTITUTE IN BYDGOSZCZ
In
2010 an examination of morphological traits in the collection of
ecotypes of the bird’s foot trefoil was carried out by the Bydgoszcz
Research Division of Plant Breeding and Acclimatization Institute. 6
chosen ecotypes and one cultivar were compared in detail in the study.
They stated, that progeny of ecotypes of the bird’s foot trefoil coming
from natural location are keeping traits of the description and dynamics
of the growing, it is possible to assign to the dissimilarity for
conditions of their habitations of the origin. Substantial differences
referred between ecotypes in the range of regrowth after moving the
vegetation and the capacity for the regeneration after cutting.
Key words: Lotus corniculatus, collection of ecotypes, morphological traits

Analiza możliwości odzyskiwania ciepła odpadowego w przemyśle rafineryjnym z wykorzystaniem układów ORC
ANALYSIS OF WASTE HEAT UTILIZATION IN THE PETROCHEMICAL INDUSTRY WITH THE ORGANIC RANKINE CYCLE SYSTEM USAGE
One
of the challenges for contemporary technology is seeking new
opportunities for electricity production, especially through waste or
unused energy utilization processes. It is important from an economical
and technological, as well as environmental point of view. Systems based
on the Organic Rankine Cycle (ORC), designed for waste heat recovery
processes and dedicated for application in existing industrial
installations, become one of the most desirable solutions in this field.
The following paper describes a preparation of ORC technology for the
refining industry, where the heat from the facility, mostly
unproductively wasted, can be reused as a source of additional
electricity. The process of working fluid selection for such a system
and the possibility of non–invasive improvement of an existing
installation have been outlined. Also, the potential benefits of
economic and ecological solutions have been identified and shown.
Key words: Organic Rankine Cycle, refining industry, waste heat usage, system design, working fluids.

Ocena
toksyczności osadu poflotacyjnego (zbiornik „Wartowice”) przed i po
zastosowaniu biopreparatów z wykorzystaniem testu IQ–TOX TEST
THE
ASSESSMENT OF TOXICITY OF THE POST– FLOTATION SLUDGE FROM FLOTATION
TAILING TANK “WARTOWICE” BEFORE AND AFTER THE APPLICATION OF
BIOPREPARATION WITH THE USE OF IQ–TOX TEST
In the process of
copper ore enrichment a large quantities of post–flotation sediments are
created. This toxic sludge must be deposited within a special areas
called post–flotation tailings. These types of landfills pose a threat
to the surrounding environment. Thus, the problem will refer to future
restoration of these areas due to their high toxicity and lack of
vegetation in the area of this type of waste landfills. We studied one
of these landfills “Wartowice”. In order to conduct a future proper
revitalisation it is recommended to assess the toxicity of sediments
before and after addition of special mixture which could reduce the
toxicity of sediments. The IQ–Tox Test – yet not used to assess this
type of pollution – was applied for our studies. We found that
post–flotation sediment proved to be highly toxic to the Daphnia magna
before the application of nutrients, but after the addition the mixture
of autochtonous bacteria, biosurfactants and inorganic waste the
toxicity of sediments decreased significantly. The application of
selected components of mixture (autochtonous bacteria or biosurfactants
alone) without the addition the inorganic waste does not cause the same
strong effect.
Key words: biopreparation, revitalization, post–flotation sludge, copper, IQ–Tox
