Opis:
The role of railway network in the internal passenger and heavy traffic is continuously decreasing. Regarding the number of passengers, proportion of the railway out of the internal passenger transport was more than 20% less in 2000. The railway passenger transportation suffered a setback in shorter distances in the last decades. In case of railway transportation of goods both the carriage distance and the quantity of goods have decreased. Content of the load has changed, too. Comparing to the previous one, quantity of the transported building materials, metal waste, ores and coal etc. lessened. In contrast with it proportion of agricultural products, machines has increased. It is worth examining the changes in connection with the passenger and heavy traffic in the last few years not only in country level but in the level of several settlements, as well. In settlements’ life a transportation route of the infrastructural sphere plays an important role. In this essay it is aiming to examine the changes in railway traffic of town Mezohegyes, a settlement on the Southern part of the Hungarian Plain, between 1990 and 2006. Research work of this kind has been carried out about town Mezohegyes earlier.
Rola sieci kolejowej w wewnętrznym ruchu pasażerskim, nawet biorąc pod uwagę duży ruch uliczny ciągle maleje. Zależnie od liczby pasażerów proporcje ruchu kolejowego w stosunku do zewnętrznego transportu pasażerskiego były o 20% mniejsze niż w roku 2000. Kolejowy transport pasażerski cierpiał z powodu regresu popularności w ostatnich dekadach, szczególnie na krótkich dystansach. W przypadku kolejowego transportu towarów, zarówno odległości przewozów jak i ilości towarów zmalały. Zawartość ładunków także się zmieniła. W porównaniu do wcześniejszych typów ładunków ilość materiałów budowlanych, złomu, rud oraz węgla zmalała. Wzrosła natomiast ilość transportowanych tą drogą produktów rolnych oraz maszyn. Warto, więc przeanalizować zmiany w ruchu pasażerskim oraz w transporcie ciężkim w ostatnich latach nie tylko na poziomie krajowym, ale i na poziomie kilku obszarów zaludnionych. W funkcjonowaniu danego obszaru, sfera infrastruktury pełni ważną rolę. W niniejszej pracy celem jest analiza zmian ruchu kolejowego w mieście Mezohegves, miejscowości w południowej części Niziny Węgierskiej w latach od 1990 do 2006. Badania tego typu zostały przeprowadzone w odniesieniu do tego miasta już wcześniej.

Opis:
The foundry industry is looking for solutions that improve the quality of the finished product and solutions that reduce the negative impact of the industry on the natural environment [26]. This process leads to work on the use of new or previously unused materials for binders. Organic and inorganic foundry binders are replaced by renewable materials of plant origin to meet the requirements of both the foundry customers and the environmental and health and safety regulations. The aim of this work was to identify the applicability of renewable and organic malted barley binder in moulding sand technology. The influence of the malt binder content on dry tensile strength, dry bending strength, dry permeability, dry wear resistance and flowability were evaluated. The results show that the malted barley binder can be self contained material binding the high-silica sand grains. Selected mechanical properties of moulding sands were found to increase with an increase in binder content. It was observed that malted barley binder creates smooth bonding bridges between high-silica sand grains.

Opis:
Hydrophobic surgical forceps of end-effectors for laparoscopic operations or minimally invasive surgery were developed through powder injection molding (PIM) and surface treatment. Processing conditions for mixing, debinding, and sintering were investigated to produce defect-free components. An optimum solid loading was determined by torque rheometry experiments. The optimized processing conditions for debinding and sintering were designed through the measurement of weight loss and shrinkage behavior by thermogravimetric analysis and dilatometry experiments. After producing the surgical forceps based on the optimized processing conditions via PIM, surface treatment was carried out to generate the hydrophobic structure on the surface.

Opis:
5.8S ribosomal RNA plays an important role in protein synthesis and eukaryotic ribosome translocation. Contact DNA insecticides based on antisense fragments of 5.8S ribosomal RNA gene of gypsy moth Lymantria dispar L. showed prospective insecticidal activity on its larvae. The most pronounced insecticidal effect was found for antisense fragments 10 and 11 nucleotides long (oligoRIBO-10 and oligoRIBO-11), whereas 12 nucleotides long fragment (oligoRIBO-12) caused the lowest level of insect mortality. This data corresponds to results obtained earlier using rabbit reticulocyte and wheat germ extracts, where maximum inhibition of protein synthesis was observed when a relevant oligomer 10-11 nucleotides long was used, whilst longer chain lengths resulted in reduced inhibition. Using oligoRIBO-11 fragment we have shown penetration of antisense oligonucleotides to insect cells through insects’ exoskeletons. MALDI technique registered the penetration of the oligoRIBO-11 fragment into insect cells after 30 min and a significant response of insect cells to the applied oligonucleotide after 60 min, which indicates not only that the oligonucleotide enters the insect cells, but also the synthesis of new substances in response to the applied DNA fragment. Contact DNA insecticides developed from the L. dispar 5.8S ribosomal RNA gene provide a novel biotechnology for plant protection using unmodified antisense oligonucleotides.

Opis:
Currently, the use of insecticides is an acute problem. Due to rapid population growth, the primary task is to increase food production. Beyond abiotic factors (drought, soil salinity, etc.) that reduce crop yields, farmers face problems with insect pests that can decrease crop productivity up to 60%. Also, insects are carriers of severe viral and protozoan human diseases. The need for application of insecticides is not questioned but many of them cause resistance of insect pests to them. This, in turn, leads to the necessity to invent new insecticides that are safe and more effective for long-term use. Preparations based on conservative parts of nucleic acids, particularly contact DNA insecticides, could be used to solve insecticide resistance problem as control agents which are well-tailored to target insect pests. This mini review is devoted to these issues.

Opis:
Effective control of Leptinotarsa decemlineata remains an urgent problem for agriculture worldwide. Minimization of the use of non-selective neonicotinoid insecticides, such as thiomethoxam, is an actual vector of development of potato cultivation. In this rapid communication, we show the prospect of the topical use of short unmodified antisense fragment of L. decemlineata CYP6B gene as a DNA insecticide. Investigated parameters, namely, number of larvae per plant, aboveground biomass, yield and number of potatoes produced per plant indicate the possibility of this post-genomic approach as a safe and effective method of L. decemlineata control.

The presented research was aimed at searching for an exact and effective method of determining moisture content in traditional moulding sands. By measuring resonance frequency and quality factor of a waveguide resonance cavity, relative permittivity was determined for different synthetic moulding sands. Analysis of the presented results confirms a linear relation between relative permittivity values and moisture content values in the selected traditional moulding sands. The obtained linear relationship can be used as a reference characteristic for evaluation of humidity of moulding sand.

Opis:
In this work, the influence of microwave drying parameters such as irradiation time and microwave power level on the properties of synthetic moulding sands is presented. Determination of compressive strength Rcs, shear strength Rts and permeability Ps of synthetic moulding sands with the addition of two different bentonites, after drying process with variable microwave parameters were made. The research works were carried out using the microwave oven with regulated power range of the electromagnetic field. From the results obtained, the significant influence of both drying time and microwave power level on the selected properties of moulding sands was observed. In comparison to the conventional drying method, microwave drying allows to obtain higher compressive strength of the synthetic moulding sand. The influence of application microwave irradiation on permeability was not observed. Higher strength characteristics and shorter drying time are major advantages of application of the electromagnetic irradiation for drying of the synthetic moulding sand with regard to conventional drying method.

Opis:
In this short communication describing experiments carried out on the larvae of two insects, Unaspis euonymi Comstock (feeding on Euonymus japonicus Thunb.) and Dynaspidiotus britannicus Newstead (feeding on Laurus nobilis L.), we evaluate for the first time the efficiency of using DNA insecticides in the control of sap-sucking insects, including armored scale insects. Over a period of 10 days, high insect mortality was detected in both U. euonymi and D. britannicus, accompanied by a significant decrease in the concentration of target RNAs. At the same time, no visible changes were observed when the leaves of the host plants were subjected to treatment with DNA insecticides for one month. The results show the high efficiency of DNA insecticides used against hemipteran insect pests. It is noteworthy that the high efficiency of DNA insecticides and their low cost in comparison with RNA preparations provides a safe and extremely promising potential vehicle for the control of sap-sucking insects.

Opis:
Current need of the social integration of people with a handicap, either physical, social, or other, finds significant professional response in a field of pre-school and elementary education. In the accordance with the request of holistic child's personality development (harmonious integration of its cognitive, social-emotional, and perceptual-motoric areas) the education by art seems to be helpful and effective in removing barriers and deepening child's skills to understand and respect the otherness and also as one of the effective ways leading to the social acceptation and inclusion of people with some kind of a handicap. Paper deals with the possibilities of educational use of illustrated books for children and youth, which thematize one of the handicap types – visual impairment. It roots from the assumption of high effectivity of the experiential methods (“through personal experience to understanding”) and examines inclusive thinking formation options and attitudes of intact pupils through experiential activities, which use illustrated books thematizing blindness. Solution of the issue comes from the analysis and comparison of the poethological aspects of artistic expression of such handicap in concrete book titles. There are compared artistic-expressive and receptive specifics of various illustrative approaches, particularly their aesthetic-experiential potential – extent of possible sensor, emotional, and cognitive experiences, which offer various modalities of the illustrative rendering of visual impairment to the child's recipient. The same attention is given to their ethical and axiological reflection. In the context of these findings, there are defined paradigmatic differences between the books illustrated in traditional ways and artistically experimental books. Following this, there are outlined alternative models of the didactical application of the issue.
