Abstract

Results of improvement of utility coefficient of X-ray digital scanning apparatuses and reduction of patient radiation dose are discussed. The multiline detector PR4000 was developed to attain this goal. This detector implements the time delay principle and signal averaging method. The pixel size is controlled in the detector. This provides an increase in the diagnostic capacity of the X-ray scanner. X-Ray digital scanning apparatus ARSTs-02-N with detector PR4000 provides diagnosis of both bone structure (spatial resolution, ≥4 pairs of lines/mm) and X-ray diagrams with resolution ≥2 pairs of lines/mm. Radiation dose in lateral projection of the patient’s lumbar segments is reduced.

Abstract

The involvement of upper electron-excited states in bacterial bioluminescence process was studied with excitation energy-accepting molecules. The fluorescent aromatic compounds, anthracene and 1.4-bis(5-phenyloxazol-2-yl)benzene, were chosen. Energies of their lowest excited singlet states are higher than the energy of the analogous state of the bioluminescence emitter; their absorption spectra and bioluminescence do not overlap. Hence, the excitation of these molecules by singlet–singlet energy transfer or by light absorption is excluded. Sensitized fluorescence of these compounds in the bioluminescence systems has been recorded, indicating the activity of upper electron-excited states in the bioluminescent process.

Abstract

An investigation was made of the relationships governing the photochemical mechanism of formation of light-induced gratings in solid polymer solutions of a dye with a high quantum yield of the triplet states. The combined analysis of the results of real and numerical experiments was made for a solution of eosin K in gelatin. The protonation rate constant of the dye was measured and the dependence of the diffraction efficiency on the duration of irradiation was explained taking diffusion of the dye into account. A method was proposed for determination of the duffusion coefficient in a spatially modified interference field of the laser radiation. The diffusion coefficients were found.

Abstract

The mechanism of formation of light-induced amplitude gratings in a rigid solution of eosin K in gelatin was studied. Spatial modulation of the absorption coefficient of the recording medium was caused by conversion of the dye to the colorless form as a result of photosensitized proton transfer from the gelatin to eosin.

Abstract

Complex bioluminescence spectra of photoproteins from marine coelenterates - jellyfish Aequorea victoria and hydroid Obelia longissima, and photoluminescence spectra of the bioluminescent reaction products (Ca(2+)-discharged photoproteins) were deconvolved into components. The bioluminescence spectra of aequorin were found to include three, the bioluminescence spectra of obelin - four, and the photoluminescence spectra of the Ca(2+)-discharged photoproteins - only two components. The spectral components were assigned to one unionized and three ionized forms of coelenteramide. The changes in acidity of the excited coelenteramide molecule are discussed. The differences in bioluminescence and photoluminescence spectra are considered, with protonic environment of coelenteramide taken into account.

Abstract

Influence of excitation energy transfer in binary solid solution ( > in gelatin) on energy yield of photoproduct and diffraction efficiency of photochemical amplitude-phase light-induced grating is investigated. It is shown, that energy values necessary for photobleaching of eosin Y in mono and binary solutions are different. Their relative energy variation lies in the range 1,1-1,9 during all exposure time. Both the yield of photoproduct and diffraction efficiency of amplitude-phase light-induced grating can serve as the indicator of excitation energy transfer.

Abstract

The search for the methods of detoxication is a keydirection in modern ecology and biotechnology. One ofthe possible ways of detoxication of pollutants may bethe use of humic substances—the products of naturaltransformation of various organic substances. Today,more and more data on the ability of humic substancesto decrease the detrimental influence of toxicantsappear [1, 2]. Earlier, the effect of detoxication wasstudied using classic test systems, such as fish, algae,crustaceans, and plants [2–6].However, despite the long-term experience of study-ing the properties of humic substances, the question onthe mechanism of the detoxicating effect of humic sub-stances remains open. It was assumed that the detoxi-cating properties of humic substances are determinedby their ability to reduce oxidants. The presence inhumic substances of phenolic groups and fragmentscarrying unpaired electrons allows to assume the possi-bility of transition (in particular, bivalent mercury) intoreduced and, respectively, less toxic forms upon inter-action with humic substances [7, 8]. It was alsoassumed that toxicants are bond by humic substances,which prevents penetration of such large aggregatesinto cells [9].To study the mechanisms of detoxication of toxi-cants by humic substances in detail, simple test systems(such as luminous bacteria) are especially promising.They have great advantages over the biotests that wereused earlier due to high rate of analysis, sensitivity,simplicity, and possibility of instrumental recording oftoxicity.This study is devoted to investigation of the mecha-nism of detoxication of solutions of organic oxidantsusing humic substances. Quinones—the products ofoxidation of the very widely spread organic pollutants,phenols, were chosen as model organic substances.MATERIALS AND METHODSIn this study, we used a series of quinones with dif-ferent redox characteristics: 1,4-benzoquinone, tet-rafluoro-1,4-benzoquinone, methyl-1,4-benzoquinone,tetramethyl-1,4-benzoquinone, and 1,4-naphto-quinone.The toxicity of quinones was assessed using thebioluminescence biotest Microbiosensor 677F [10],which is based on lyophilized luminous bacteria

Abstract

The laser irradiation of the thin films of solid solution of eosin in gelatinous matrix in the first and some upper dyes absorption bands leads to decrease of films optical density due to reaction of photoreduction. In the paper the kinetic of photoreduction of the dye eosin K in polymeric matrix in three cases of irradiation was experimentally investigated: a) irradiation by N2 laser (λ=337nm, second band of absorption, π=2 nsec, repetition rate-100 Hz, average power-2,2 mW), b) irradiation by Ar-laser (λ=488 nm, first band of absorption, 6,5-12 mW), c) under a simultaneous action of both Ar and N2-lasers. It was demonstrated that the most effective reaction of photoreduction took place in case of direct populating of upper singlet states with probable following nonradiative transition into equienergetic triplet states (energy ranges 35000-45000 sm-1).© (2004) COPYRIGHT SPIE--The International Society for Optical Engineering.

Abstract

The hypothesis of activity of the upper electron-excited states of the bacterial bioluminescent emitter was verified using dye molecules as foreign energy acceptors. Six compounds were selected having fluorescent state energies ranging from 25,700 to 32,000 cm(-1) (anthracene, pyrene, 1.4-bis(5-phenyloxasol-2-yl)benzene (POPOP), p-bis(o-methylstyryl)benzene (MSB), 2-methoxy-naphtalene, p-terphenyl), exceeding that of the bioluminescent emitter (22,000 cm(-1)). Their absorption spectra do not overlap with the bioluminescence spectrum; the trivial light absorption and the intermolecular resonance S-S energy transfer were excluded. Bacterial bioluminescent spectra of the coupled enzyme system NADH:FMN-oxidoreductase-luciferase in the presence of MSB were presented as an example. The weak sensitized fluorescence of MSB was registered. The results obtained have confirmed the activity of the energetic precursor in the bacterial bioluminescence. Its energy can be located in the interval of 26,000-27,000 cm(-1).

Abstract

An investigation was made of the photoreduction kinetics of a dye in a solid polymer solution under the influence of laser radiation corresponding to the band of the first singlet — singlet transition. Participation of higher triplet states was considered in a model of the photoreduction of a dye characterised by a high intersystem crossing yield. An analytic solution was obtained for a system of kinetic equations. This solution takes into account the difference between the photoprocess rates. It is shown that a linear dependence of the effective dye-photoreduction rate on the laser radiation intensity can serve as a test of the participation of higher triplet states in the reaction. A comparison of the theoretical and experimental results obtained in the present study is used to determine the ratio of the photoreduction and deactivation rate constants of the higher triplet state of eosin K.
