Opis:
W artykule zaprezentowano źródła finansowania inwestycji małych i średnich przedsiębiorstw. Ich ocena została przeprowadzona na podstawie informacji statystycznej oraz badań ankietowych firm funkcjonujących na terenie województwa lubelskiego. Wydatki inwestycyjne w badanej grupie podmiotów gospodarczych w ostatnich latach znacząco wzrosły, lecz nadal są niskie. Finansowane są głównie środkami własnymi. Poziom innowacyjności inwestycji wprawdzie rośnie, lecz jest niewystarczający. Konieczne jest wsparcie procesów innowacyjnych w małych i średnich przedsiębiorstwach poprzez odpowiednie zmiany w przepisach prawnych i działania władz lokalnych.
The article presents the sources of financing of small and medium-sized enterprises. Their evaluation was based on statistical information and surveys of businesses operating in the Lublin province. Capital expenditures in the group of economic operators in recent years significantly increased, but still low. Are mainly financed with own funds. The level of innovation investment, while growing, but it is insufficient. It is necessary to support innovation processes in SMEs by appropriate changes in legislation and the activities of local authorities.

Opis:
The widely known limitations to the further development of wind power (Act [1], modest auctioning) have made photovoltaic plants very popular in quantitative terms, micro-scale units as well as systems with several hundred kW capacity or more. Unexpectedly for investors, in addition to various technical and economic problems, the charges for reactive power flow from PV sources to the grid have become an issue. The financial implications of this seemingly small scale flow can be severe for PV investors because of restrictive distribution tariffs. This paper analyses this problem from the prosumer micro-plant perspective. Potential financial burdens arising from PV system characteristics have been analysed, and the technical rationale of the tariffs has been assessed and then questioned. There are also proposals to change the policies of the operator with regard to the issue of reactive power generation by distributed sources.
Powszechnie znane ograniczenia dalszego rozwoju energetyki wiatrowej (ustawa [1], skromny wymiar aukcji) spowodowały, że obecnie w sensie ilościowym bardzo rozpowszechnione stają się instalacje fotowoltaiczne, zarówno w skali mikro, jak też w odniesieniu do mocy kilkuset kilowatów i większych. Nieoczekiwanie dla inwestorów, oprócz różnych problemów technicznych i ekonomicznych, pojawił się problem opłat za przepływ mocy biernej od źródeł PV do sieci. Finansowe konsekwencje tego pozornie niewielkiego przepływu mogą być dla inwestorów PV dotkliwe ze względu na restrykcyjne zapisy taryf dystrybucyjnych. W artykule poddano analizie ten problem z punktu widzenia mikroinstalacji prosumenckich. Przeanalizowane zostały potencjalne obciążenia finansowe wynikające z właściwości układów PV, równocześnie oceniono techniczne uzasadnienie zapisów taryfowych, poddając je w wątpliwość. Przedstawione zostały również wnioski w zakresie zmiany podejścia operatorów do kwestii generacji mocy biernej przez źródła rozproszone.

Opis:
Abdominal pain is one of the main symptoms of pancreatic diseases, including chronic pancreatitis (CP). Once the disease is in remission, pain management is a key element of treatment. Co-analgesics may also be used at any stage of analgesia, among which antiepileptic drugs such as pregabalin. The first data on the beneficial effect of pregabalin on pain in the course of CP was published in a clinical trial in 2011, and it has been known since 2015 that the analgesic effect of pregabalin on CP has a different mechanism of action than conventional analgesics. Currently, research is focused on combining pregabalin with antioxidants and on methods to predict the patient's response to pregabalin administration. Based on current research, pregabalin appears to be a very useful agent for the pharmacologic treatment of pain in the setting of CP.

Opis:
All over the world, including Poland, interest in the organic farming is growing. It is based on an attempt to minimize human impact on the environment while maintaining the natural functionality and productivity of the agricultural system. At the same time, every human activity in the natural environment results in greater or lesser changes in the soil ecosystem. Organic farming also has an impact on physical and chemical parameters and soil biological activity. These changes should be monitored and considered in the context of long-term land management. This review focuses on the impact of the organic farming system on soil biological activity and diversity of soil microorganisms.

Opis:
The article presents problems connected with the biodiversity of soil microorganisms occurring on selected protected areas. Based on the literature, authors attempt to explain the concept of biodiversity, the role of soil in the natural environment and the importance of soil microorganisms. The article also presents selected anthropogenic factors that influence microorganisms found in soils under different forms of protection. The large species diversity of soil microorganisms is closely related to their functions in the soil. Soil microorganisms participate in all processes occurring in the soil. They influence humus formation, increase soil fertility, provide plants with nutrients by decomposing organic matter and fight pathogens. The special attention focused on the broad concept of biological diversity as a form of preservation possibly the greatest richness of life on Earth. Ecological conditions prevailing in the different ecosystems affect the modification of the environment and force adaptation of organisms (including microorganisms) into the habitat. To preserve the diversity of the microorganisms, it is important to protect their habitat – the soil. Intolerance to certain environmental conditions and competition between microorganisms causes abnormal functioning of ecosystems and significant depletion of biodiversity. However, the main cause of the microorganisms biodiversity loss is the human pressure on the natural environment. Human activity causes the extinction of many species of plants and animals and has a negative impact on the soil environment. This in turn affects the functioning, abundance and biodiversity of soil microorganisms. In areas with significant natural values such as forests and protected areas (national parks) biodiversity of microorganisms is maintained at a much higher level than in the case of productive soils. The environmental protection leads to the equilibrium in the natural systems and its biotic and abiotic components, including biodiversity. Therefore, the need to create places of special protection such as national parks, nature reserves, landscape parks, etc. is very much justified.

Opis:
Glomaliny to glikorpoteiny grzybowe, które są wyjątkowo odporne na degradację (obecne w glebie nawet od 10 do 30 lat) oraz trudno rozpuszczalne w wodzie. Celem niniejszej pracy była ocena zawartości ogólnych i łatwoekstrahowalnych glomalin w archiwalnych próbkach glebowych. Do badań wybrano 15 próbek glebowych z doświadczeń polowych z 1994 roku dotyczących uprawy jęczmienia jarego. Badane gleby pochodziły z różnych regionów Polski oraz reprezentowały różne typy gleb. Gleby charakteryzowały się także dużym zróżnicowaniem właściwości fizykochemicznych i biologicznych. Przeprowadzone w niniejszej pracy badania wykazały obecność glomalin we wszystkich próbkach glebowych. Stężenie ogólnych i łatwoekstrahowalnych glomalin zależało głównie od typu gleby. Obecność glomalin w badanych glebach potwierdza hipotezę, iż białka te są szczególnie odporne na degradację i mogą pozostać w niezmienionej formie w glebie przez wiele lat.
Glomalines are thermostable, water-insoluble glycoproteins abundantly produced by Glomus fungi and tends to accumulate in the soil, that surrounds soil aggregates and protects them from destroying. Glomalines are especially resistant to destruction, hard to dissolve in water, while very easy dissolve in high temperature (121°C) in citrate buffer with neutral or alkali pH. These proteins have very unique physico-chemical properties performing a fundamental role in making soil structure. The content of glomalin in soil particles is significantly correlated with their stability (water resistance). It is possible that glomalin is involved in the formation of hydrophobic properties of soil, improving water and air relations in soil. Glomalines are mainly located on the surface of hyphae and spores of AM (arbuscular mycorrhizal) fungi and a hydrophobic substances covers and protects it from the degradation by other microorganisms. It also increases the stiffness and the durability of the cell of fungi facilitating their distribution in the soil. Production and distribution of glomalin in soil involves many factors, both related to the physico-chemical properties of soil and plant and fungal species. The structure of soil and its chemical properties have a significant effect on the growth of mycelium, and therefore the glomalin content. Glomalins are very resistant to degradation. As aging hyphae outside the root and the roots of plants, biomass mycelium of AMF fungi is degraded – but not glomalin. This protein is unchanged is able to survive in the soil even decades. Glomalins commonly occur in different types of soils. The aim of the study was to demonstrate the presence of total and easy extractable glomalins in archival samples of soil from the collection of soil Department of Microbiology IUNG-PIB in Puławy. The study selected 20 soil samples from field trials in 1994 with the cultivation of barley. The soil samples survey from various Polish regions and represented different types of soils. Soils were characterized by different physical, chemical and biological properties. The studies carried out in this paper have shown the contents of glomalin in all soil samples. The concentration of total and easily extracted glomalin depend mainly on the type of soil. The presence of glomalin in soils confirms the hypothesis that these proteins are particularly resistant to degradation and can remain unchanged in the soil even decades.

Opis:
In Mossbauer spectra of the Sołtmany meteorite we identified four iron-bearing minerals: olivine, pyroxene, kamacite and troilite. The distribution of iron among these minerals is different in the Sołtmany meteorite from this distribution in the Baszkowka meteorite. As Sołtmany and Baszkowka meteorites are ordinary chondrites type L (both falls), differences in the distribution of iron over the four main iron-bearing mineral phases could be the basis for a new classification of L-type ordinary chondrites. Small amounts of taenite were also observed in the Sołtmany meteorite. The ratio of iron in kamacite and taenite in the Sołtmany meteorite was found to be about 3. No Fe3+ could be detected.

Opis:
Iron present in the human brain plays important role in neurodegenerative diseases like Parkinson and Alzheimer diseases. Brain iron is mainly stored within globular protein called ferritin. Mössbauer spectra of brain tissue are asymmetric doublets at 300 K and 90 K. This asymmetry is slightly bigger in the case of samples taken from diseased subjects. Reason for this is still unknown. Few possible causes of aforesaid difference had been discussed. Nanometer-size of ferritin iron cores, pathological protein influence were taken into account. It was also discussed if experimentally available statistics is sufficient to obtain reliable asymmetry coefficient from Mössbauer spectra. Physical experiment were reproduced by means of computer simulations. Nevertheless, the reason for the asymmetry has not been completely elucidated yet.

Grains of three cultivars of each cereal: winter wheat (Triticum aestivum L. – Tonacja, Bogatka, Satyna), winter rye (Secale cereae L. – Stanko, Dańkowskie Złote, Amilo) and winter barley (Hordeum sativum L. – Laverola, Mertada, Merk) were examined. In addition, phenolic acids were identified in these grains, and the content of the identified acids, i.e. ferulic, vanillic, p-coumaric, protocatechuic, p-hydroxybenzoic, syringic, sinapic and caffeic, was determined. The antioxidant properties of phenolic acids were examined using the free radical scavenging method against a stable 2.2-diphenyl-1-pikrylhydrazyl radical (DPPH). The antiradical efficiency of phenolic acids depended on the duration of a reaction and genotype-specific properties. The data showed that different winter cereal seed extracts were able to quench 15-47% of DPPH radical solution and to exhibit potent radical scavenging activity. Results of the determinations of the content of phenolic acids in grains of the cultivars correlated with the activity of their extracts. The tested cereal grains were characterized by different levels of the identified phenolic acids, depending on the generic and specific characteristics. Differences in the content of phenolic acids may be subject to genetic traits, environmental factors and different analytical procedures. Cereal kernels with a higher phenolic acid content also exhibited a higher antioxidant activity of extracts with these compounds. Kernels of winter barley cv. Metaxa with a higher content of phenolic acids were also characterized by higher antioxidant activity than those of cvs. Merle and Laverola. The lowest content of phenolic acids was observed in winter rye cv. Stanko. 5-day seedlings showed a statistically significant increase in phenolic acids (ferulic, p-coumaric, protocatechuic, p-syringic, sinapic and caffeic) and the high antioxidant activity. Winter cereal seed extracts were able to quench 15-47% of DPPH radical solution and exhibited potent radical scavenging activity.

Opis:
This analysis was performed as a part of the palaeomagnetic project focused on the reconstruction of the palaeogeographic position of the Svalbard Archipelago and adjacent crustal units (European Arctic) in the Palaeozoic and Mesozoic. Three rock formations - Cambrian, Devonian and Carboniferous were sampled in the area of Hornsund, southern Spitsbergen. The main aim of the presented study is to identify ferromagnetic minerals (sensu lato) - the carriers of the natural remanent magnetisation in the investigated rocks. A wide range of magnetic methods were used: the Lowrie tests, unblocking temperatures determinations and the measurement of coercivity spectra as well as the Mössbauer studies. In Devonian and Carboniferous samples all applied methods indicate the domination of the hematite natural remanent magnetisation carrier. In Cambrian rocks magnetic measurements reveal a mixture of ferromagnetic (sensu lato) minerals with varying coercivities and unblocking temperatures. The Mössbauer data improve the identification, suggesting that in Cambrian rocks the carrier of the dominating natural remanent magnetisation component is maghemite.

Opis:
A complete set of procedures comprising of the induction of haploid embryo development by pollination with irradiated pollen, embryo isolation and in vitro culture, haploid plant development, chromosome doubling by regeneration from leaf explants, acclimatization, self-pollination of DH plants and assessment of DH lines was performed in cucumber. Haploid and doubled haploid plants were obtained from all eight genotypes used in the study. The donor plant genotypes were evaluated by comparing the number of haploid embryos and DH plants obtained from each genotype. The influence of the donor plant genotype and its age on the regeneration and the yield of DH plants were evaluated. In order to optimize the method of chromosome doubling, the composition of medium was modified and the explants were divided into four groups with regard to the leaf sector used for regeneration. Acclimatization of DH plants to the greenhouse conditions was improved. Uniform, useful in breeding, DH lines were obtained.
Przeprowadzono pełną procedurę otrzymywania podwojonych haploidów ogórka, która składała się z następujących etapów: indukcji rozwoju haploidalnych zarodków poprzez zapylenie napromieniowanym pyłkiem, izolacji i kultury in vitro zarodków, rozwoju roślin haploidalnych, podwojenia liczby chromosomów poprzez regenerację z eksplantatów liściowych, aklimatyzację, samozapylenia podwojonych haploidów i charakterystyki linii DH. Haploidy i podwojone haploidy otrzymano w przypadku wszystkich ośmiu genotypów wykorzystanych w doświadczeniach jako rośliny donorowe. Rośliny donorowe porównano pod względem liczby haploidalnych zarodków i roślin DH jaką z nich otrzymano. Oceniono wpływ genotypu i wieku rośliny donorowej na regenerację i liczbę otrzymanych regenerantów DH. W celu optymalizacji metody podwajania liczby chromosomów zmodyfikowano skład pożywki, a eksplantaty podzielono na cztery grupy w zależności od sektora liścia z którego zostały pozyskane. Ulepszono sposób aklimatyzacji roślin DH do warunków szklarniowych. Otrzymano wyrównane linie DH, które mogą być wykorzystane w hodowli.

Opis:
Bovine tuberculosis (BTB) is a dangerous zoonosis which presents a serious problem for endangered species such as European bison (Bison bonasus). Little is known about the influence of parasitic co-infections on the course and diagnosis of tuberculosis in animals. The best known co-infection in cattle is Fasciola hepatica and Mycobacterium bovis. The aim of this study was to review the most recent literature regarding tuberculosis and parasite co-infection in ungulates and relate the results to European bison. Our findings indicate that any comprehensive diagnosis of BTB should include parasitological monitoring, and the possible impact of such invasions on cellular response-based tuberculosis tests should be taken into account. The diagnosis of BTB is complex, as is its pathogenesis, and parasitic infestations can have a significant impact on both. This should be taken into account during further research and monitoring of tuberculosis in European bison.

Opis:
Motor symptoms of Parkinson's disease are caused by a progressive degeneration of substantia nigra, a small structure located deep in the brain. The cause of this process is unknown but may be related to iron mediated oxidative stress. The aim of this study was to understand the mechanism of the change of magnetic resonance and ultrasound signals found in patients with Parkinson's disease, which were attributed by several authors to an important increase of the concentration of iron in substantia nigra. USG and MRI measurements were performed on phantoms simulating human brain to which high amounts of iron were introduced. The USG signal was unaffected by insertion of iron-loaded ferritin, while it was by insertion of glial tissue. Injections of iron-loaded ferritin and iron ions to the phantoms decreased $T_2$ relaxation time. Our results suggest that the observed change of the signal from Parkinsonian brains is probably due to a proliferation of glia and not to an increase of the concentration of iron.

Opis:
The suggestion of sending a Mössbauer spectrometer to the surface of Mars was elaborated in 1988 year. In 1989 realization of this project was taken by scientists from Western Europe and USSR. Finally a Mössbauer spectrometer adapted to measurements on the surface of Mars was constructed by an international team under the guidance of G. Klingelhöfer. Mössbauer data from Mars are available for open public access on a web site of Planetary Data System. Based on these data the catalogue of Martian Mössbauer spectra was prepared and located on the web site of one of the author (JGF). The aim of the construction of this catalogue was to create the possibility to compare quickly spectra from different places on the Martian surface.
