    In the result of application of the developed technology, Au, Ag and Pd were adequately replaced with nonprecious metal alloys. The nanotechnologies using the electroless deposition are much more advantageous and simpler than other expensive methods of nanotechnology and allow the fabrication of photocatalysts and catalysts by means of deposition of nanocrystals having the specified properties on high-dispersive powder like semiconductors.

    The stoichiometry of the metal complexes formed between nickel and the ligand β-glucoisosaccharinic acid (β-GISA) and a racemic mixture of enantiomers of xyloisosaccharinic acid (XISA) has been determined at both neutral and alkaline pHs. Bjerrum plots, Job's plots and conductance measurements indicated that for each of the systems one to one Ni(ligand) complexes were formed at near neutral pHs (13) sparingly soluble Ni2(ligand)(OH)4 complexes were formed. The stability constants for the Ni(β-GISA), Ni(α-GISA) and Ni(XISA) complexes formed at neutral pH were determined under identical conditions using polarographic studies. The measured stability constants for Ni(β-GISA) (log10 β = 1.94 ± 0.15) and for Ni(α-GISA)(log10 β = 2.07 ± 0.13) are very similar; the value measured for the Ni(XISA) complex (log10 β = 0.83) was an order of magnitude smaller. The stability constants for the Ni2(Ligand)(OH)4 complexes formed at highly alkaline pHs were determined using the Schubert method. The measured stability constant for Ni2(β-GISA)(OH)4 (log10 β = 30.6 ± 0.5) was an order of magnitude bigger than the value for Ni2(α-GISA)(OH)4 (log10 β = 29.0 ± 0.5) measured under identical conditions. Attempts to measure the stability constant for Ni2(XISA)(OH)4 were unsuccessful; Ni2(XISA)(OH)4 complexes were not present in significant amounts at high pH to allow the log10β value to be determined by the Schubert method

    The article discusses today’s organizational and procedural problems of investigation. We have presented our concrete proposals for their resolution, in particular: we tried to show the role of criminology in opening and investigation of crime and its advantages in comparison with covert operative - investigative activities.We discussed the problems, on the basis of current Criminal Procedure Law, in connection with investigation and the investigator’s human rights situation, expressed opinions regarding the restoration of the investigation institute.We expressed our attitude toward the decision of government about restoration of justice. We expressed our opinions regarding the procedural agreement and the illegal judgments

    The link between hypertension and preeclampsia/eclampsia-life-long cardiovascular risk for women

    Cardiovascular diseases remain the main cause of death and morbidity in women. Despite the active preventive measures and the reduction in the total number of morbidity and mortality rates, the rate of cardiovascular morbidity remains high in the population, moreover cardiovascular morbidity is increased in women of 35-54 years. Cardiovascular morbidity has several unique characteristics for women; pregnancy, gestational hypertension, preeclampsia/eclampsia are gender-specific risk-factors for further cardiovascular morbidity in women, it's possible to detect these risk-factors in younger age groups and start prevention as early as possible. Arterial hypertension, which is characterized by genetic polymorphism, is an important and a powerful risk factor for development of both acute and chronic cardiovascular diseases; association of arterial hypertension with different metabolic disorders suah as metabolic syndrome, diabetes seems particularly dangerous in pregnancy in terms of peri-pregnancy and life-long morbidity. Preeclampsia shares some common features with atherogenesis and metabolic changes and atherogenesis and metabolic changes, so presence of hypertension during pregnancy increases the risk of cardiovascular diseases and diabetes later in the life. Is pregnancy revealing or predisposing factor of development cardiovascular diseases is not still clear and to answer these questions more and more studies are required
