Opis:
In order to understand the roles of abscisis acid in soybean exposed to UV-C radiation, soybean seedlings were exposed to UV-C radiation and ABA was applied. The chlorophyll content, active oxygen metabolism and flavonoids content of soybean seedlings were investigated. The present study revealed that UV-C radiation significantly attenuated the chlorophyll content and suppressed PSII activity. It was observed that the contents of H2O2, malondialdehyde and O2 - were markedly increased, and the activities of antioxidant enzymes such as superoxide dismutase, peroxidase and catalase were enhanced, so were the flavonoids content, whereas the seedling height and biomass were significantly reduced. ABA application improved the activities of superoxide dismutase, peroxidase, catalase and the contents of flavonoids, decreased the contents of H2O2, MDA and O2 -, and also increased the chlorophyll content and enhanced PSII performance, thus enhancing biomass accumulation. The results suggested that ABA alleviated UV-C damage to soybean seedlings by reducing ROS generation and enhancing antioxidase activity. The isoflavones daidzin and genistein were significantly responsive to UV-C.

Opis:
The objective of this research to optimise the HPLC method was developed for quantitative determination of Pirimiphos-methyl. Chromatographic separation was achieved on a 250 x 4.6 mm i.d. reversed phase column Qualisil BDS 5u C18, Using deionized acetonitrile:water in the ratio of 85:15 v/v respectively as mobile phase. The eluent was monitored at 254 nm. A sharp peak was obtained for the Pirimiphos-methyl at 9.29 min. The UV Spectrophotometric method performed at 254 nm after full scan analysis using methanol as a solvent. The result revealed that both methods are suitable to carry out routine analysis of Pirimiphos methyl, However HPLC results showed high precise, accurate and sensitive than the UV Spectrophotometer. Hence HPLC method is suitable for trace analysis of Pirimiphos methyl in environmental samples.

Opis:
Although the analogies between the electron energy loss spectra and X-ray absorption spectra were recognized long ago, the possibility to observe the magnetic circular dichroism in the electron microscope was demonstrated only recently. This technique combines the atom specificity with the high spatial resolution of the transmission electron microscope. Being a very young technique, there are still many open questions concerning the optimization of the signal to noise ratio. In this paper we study the dichroic signal dependence on the sample thickness, acceleration voltage and incoming beam tilt angle of bcc-Fe and fcc-Ni.

Opis:
Photoluminescence properties of CeF$\text{}_{3}$ have been investigated. Two kinds of emitting centers have been identified: regular Ce$\text{}^{3+}$ sites exhibiting two close emission bands (285 and 300 nm) and a fast fluorescence (20 ns) and several physically different perturbed Ce$\text{}^{3+}$ sites giving rise to a broad emission band near 340 nm and a longer fluorescence (30-40 ns) the decay time of which varies with wavelength. An energy transfer occurs between these two kinds of centers. Scintillation properties have been studied under UV and X-ray excitation. The additional fast decay always observed at short time under ionizing radiation is interpreted by a temperature dependent luminescence quenching phenomenon due to high excitation density.

Opis:
Differences in cellular death between melanoma (Me45) cells and fibroblasts (CCL-110) were investigated after irradiation with UV-C (1.5-15 J/m²) and incubation for up to 48 h. The role of DNA double strand breaks in this process was assessed. Decrease of the Me45 cells viability began about 6 h after irradiation. The fibroblasts viability negatively correlated with the dose applied, since necrosis within this cell population began immediately after irradiation. The enhanced apoptosis of fibroblasts was observed between 6 and 24 h, while for melanoma cells, high level of apoptotic cells was still detected after 48 h. Statistically significant correlation between the percentage of apoptotic cells and DSBs was estimated for both cell lines. The melanoma cells responded differently to the UV-C radiation than did the fibroblasts. These differences were explained by deficiency of the necrotic processes as well as the delay of apoptotic melanoma response to UV-C damage.

Opis:
Folie zawierające polilaktyd jako osnowę polimerową, montmorylonit jako napełniacz oraz poli(ε-kaprolakton) jako kompatybilizator naświetlano promieniowaniem UV-C (max 254nm) w odstępach dwu godzinnych do 16 godzin. Wpływ napełniacza oraz obecności kompatybilizatora na proces fotodegradacji analizowano przeprowadzając badania właściwości termicznych, zarówno wyjściowych materiałów jak i po różnych czasach ekspozycji na UV. Pod uwagę brano między innymi następujące parametry: stabilność termiczną, temperaturę zeszklenia czy stopień krystaliczności. Otrzymane wartości wskazują, iż wprowadzenie poli(ε-kaprolaktonu) jak i montmorylonitu powoduje wzrost stopnia krystaliczności materiałów, co jest jednym z kluczowych czynników wpływających na proces fotodegradacji. Na podstawie uzyskanych wyników stwierdzono, iż obecność napełniacza podobnie jak i kompatybilizatora poprawia odporność kompozytów polilaktydowych na działanie promieniowania UV.
Films consisting of polylactide as polymer matrix, montmorillonite as filler and poly(ε-caprolactone) as compatibilizing agent were irradiated with UV (254 nm) at intervals of 2-16 hours. Effect the presence of filler and compatibilizing agent has got on photodegradation process was analyzed by examination of thermal properties of both the starting material and the material after various times of exposure to UV radiation. The following parameters were taken into account: thermal stability, temperature of glass transition as well as degree of crystallinity. Determined values indicate that the introduction of a compatibilizing agent and a nanofiller into polymer matrix increases degree of crystallinity of obtained materials. Degree of crystallinity is an important factor influencing photodegradation process. Based on obtained results it has been established that the presence of a nanofiller as well as a compatibilizing agent improves thermal stability of polylactide composites exposed to UV radiation.

Opis:
The removal of a non-steroidal anti-inflammatory drug (NSAID) diclofenac sodium salt (DCF, C14H10Cl2NNaO2) from water in two hybrid systems coupling photolysis or photocatalysis with direct contact membrane distillation (DCMD) is presented. A UV-C germicidal lamp was used as a source of irradiation. The initial concentration of DCF was in the range of 0.005-0.15 mmol/dm3 and the TiO2 AeroxideŽ P25 loading (hybrid photocatalysis-DCMD) ranged from 0.05 to 0.4 g/dm3. Regardless of the applied hybrid system and the initial concentration of DCF, the model drug was completely decomposed within 4h of irradiation or less. Mineralization was less efficient than photodecomposition. In case of the hybrid photolysis-DCMD process the efficiency of TOC degradation after 5h of irradiation ranged from 27.3-48.7% depending on the DCF initial concentration. The addition of TiO2 allowed to improve the efficiency of TOC removal. The highest degradation rate was obtained at 0.3 gTiO2/dm3. During the process conducted with the lowest DCF initial concentrations (0.005-0.025 mmol/dm3) a complete mineralization was obtained. However, when higher initial amounts of DCF were used (0.05-0.15 mmol/dm3), the efficiency of TOC degradation was in the range of 82.5-85%. The quality of distillate was high regardless of the system: DCF was not detected, TOC concentration did not exceeded 0.7 mg/dm3 (1.9 mg/dm3 in permeate) and conductivity was lower than 1.6 žS/cm.

Opis:
The development of effective processes to recover minor actinides from spent nuclear fuel cannot leave out of consideration the evaluation of the impact of ionizing radiations on safety, fluid dynamics and extraction efficiency. It is common knowledge from the literature that radiation damage mainly affects the diluents and, indirectly, the extractants [1], but a lack of knowledge remains regarding the radiolytic behavior of innovative selective actinide extraction (i-SANEX) diluents [2, 3]. As natural prosecution of the work already performed on diluted nitric acid solutions [4], 0.44 M nitric acid solutions were irradiated in contact with a mixture of kerosene + 5 vol.% 1-octanol by a Co-60 source at 2.5 kGy/h dose rate and up to 100 kGy absorbed dose, conditions of interest for the future industrial facility. Density, viscosity, acidity, nitrate anion concentration and phase transfers were systematically measured before and after γ-irradiation. This was performed because radiation-induced modifi cations of these parameters may induce alterations of both the fluid dynamics and the separation performances of the extracting system. The results suggest that the fluid-dynamics of the system should be unaltered. In fact, only slight alterations of the organic phase viscosity and of the aqueous phase acidity were measured after irradiation, suggesting the occurrence of limited phase transfers and of diluent by-products formation.

In this study, UV-C light was tested as an alternative method to inactivate microorganisms in the must of ‘Regent’ red grape cultivar. The control sample containing the microorganism diluted in a physiological NaCl solution was prepared to take into consideration different conditions of liquids, such as turbidity and colour. Additionally, the changes in the composition of polyphenol compounds in the ‘Regent’ must after UV-C exposure were evaluated. The viability of yeasts (Saccharomyces cerevisiae) and bacteria (Oenococcus oeni) significantly decreased with time; however, the highest decline was noted after the first hour of exposure. The polyphenol compound content was significantly lower after UV-C treatment and this was mainly the result of anthocyanin decomposition. The total content of flavan-3-ols and hydroxycinnamic acids and derivatives increased after irradiation.

Opis:
Processes of the combustion of liquid fuels and solid are more complex than combustion of fuel gases. With reference to liquid fuels occur additionally processes of vaporization of the fuel, and with reference to solid fuels - decomposition of the solid phase with processes of melting and vaporization, pyrolysis, or gasification. This simultaneous and also different influence of different parameters is sometimes a reason of incorrect interpretation of experimental results. The study of the theoretical model of the combustion process concerning of liquid and solid fuels and which then the model takes into account also the gas- phase, because combustion processes take place in this phase, and occurs the interaction of the phase gas- and liquid or the solid one. The theoretical model is presented basing on experimental initial researches realized in a model with reference to liquid fuels and solid ones. Researches realized in the constant volume chamber with measurements of the pressure during the process of the combustion with the use of quick photography and with measurement of the distribution of the velocity in the spray of the fuel and droplet measurements by means the laser Doppler equipment LDV and PDPA. There were obtained a good agreement of findings experimental researches with the theoretical model. Generally, on the combustion velocity of liquid fuels and solid one significant influence has a kind (laminar, temporary and turbulent) and the thickness of the thermal boundary layer.

The synthesis of Zinc oxide (ZnO) nanoparticles using plant parts is always an attractive and eco-friendly method. The present study focuses on the production of ZnO nanoparticles from Zinc Nitrate hexahydrate (Zn (NO3)2•6H2O) using the aqueous extracts of a medicinal plant Micrococca mercurialis. The plant is found to be rich in primary and secondary metabolites such as proteins, steroids and alkaloids, which are responsible and enhancing the biogenic synthesis of ZnO nanoparticles. Leaves, stems, roots and fruits of M. mercurialis were used to prepare the aqueous extracts. The characterization and confirmation of synthesized ZnO nanoparticles was performed by UV-Visible spectrophotometer. The reaction mixtures showed significant and sharp UV absorbance peaks at 305 nm, 299 nm, 311 nm and 302 nm corresponding to the aqueous extracts of leaf, stem, root and fruits reacted with zinc nitrate respectively. It has been proved that the medicinal plant M. mercurialis can be used to synthesize ZnO nanoparticles and the biological method of synthesis of ZnO nanoparticles are safe and good alternative to the chemical and physical methods.
