Targeting the principle implementation in the system of social support

Purpose: The article aims to identify the actual problems of implementing the principle of targeting in the social protection system in Russia and to develop a set of measures to transform the mechanism of its provision based on a differentiated approach, which implies not only differences in the size of social transfers, but also on various forms of such support. Design/Methodology/Approach: As the basic approaches of the study there were chosen the theory of social investment and the conception of result-based budgeting. The study suggested the development of a more effective financial support system, the substantiation of a differentiated approach to the organization of a social system based on a single method by determining the degree of financial vulnerability of citizens and the development of methodological recommendations on the use of financial instruments to strengthen the targeting of social protection of needy citizens. Findings: The article substantiates that the necessary condition for the transformation of the social protection system to strengthen the social and financial security of needy citizens is the development of a differentiated approach in the provision of social support measures. Practical Implications: The results of the study can be implemented into the management of social protection in order to improve its efficiency and effectiveness by using the targeting of social transfers based on clear criteria of need, the differentiated approach implementation in determining the measures of social support through the use of "map of social support of citizens", expanding the application of social contract technology. Originality/Value: The set of measures proposed in the study will make it possible not only to adjust and direct social support to really needy recipients and to differentiate the volume of the support provided, but also to create conditions for the recipients of targeted protection to self-sufficiency, which, in turn, will contribute to the poverty reduction.peer-reviewe

Quantum dots desorption via high-power Nd:YAG laser pulses

In the present work, we investigated the mechanism behind the desorption of quantum dots (QDs) CdSe/ZnS (core/shell) aggregates via Q-switched Nd:YAG pulsed laser. After desorption, we trapped the aggregates in a linear quadrupole Paul trap and analyzed their dynamics using machine vision methods. We found that the number of desorbed aggregates is proportional to the laser radiation energy. The injection efficiency was 13.6% for all values of the laser pulse energy greater than 200 mJ. However, even thoughthe desorption process was also observed at lower values (<200 mJ), we did not register particles trapping in this case. This effect might be caused by the different nature of desorption at low powers (LIAD) and at high powers (desorption as a result of substrate ablation)

Conductivity, weak ferromagnetism and charge instability in α−MnS\alpha-MnS single crystal

The temperature dependence of resistivity, magnetization and electron-spin resonance of the $\alpha- MnS$ single crystal were measured in temperature range of $5 K < T < 550 K$. Magnetization hysteresis in applied magnetic field up to 0.7 T at $T=5 K, 77 K, 300 K$, irreversible temperature behavior of magnetization and resistivity were found . The obtained data were explained in terms of degenerate tight binding model using random phase approximation. The contribution of holes in $t_{2g}$ and $e_g$ bands of manganese ions to the conductivity, optical absorbtion spectra and charge instability in $\alpha -MnS$ were studied. Charge susceptibility maxima resulted from the competition of the on-site Coulomb interaction between the holes in different orbitals and small hybridization of sub-bands were calculated at $T=160 K, 250 K, 475 K$.Comment: 6 pages, 12 figure

Local head loss monitoring using acoustic instrumentation in partially full sewer pipes

After an increase in capital investment in UK sewers to reduce hydraulic capacity problems, the proportion of sewer flooding incidents now linked to blockages has increased. It is clear that if sewer operators are to continue to reduce flooding incidents, then better blockage management is now required. Sewer blockage formation is poorly understood; blockages are intermittent and occur in a number of circumstances. This paper reports on the development of low-cost acoustic instrumentation that can identify the location of a pipe blockage and then estimate the local head loss as a result of the presence of a blockage. A set of experiments were carried out in two full-scale laboratory pipes. The pipes' condition was altered by inserting blockages of different sizes. Acoustic data were recorded and presented in terms of the acoustic energy reflected from the partially blocked pipe. The results of this study show that the total reflected acoustic energy correlates with the measured head loss. A new empirical relation between the reflected acoustic energy and head loss due to a blockage is derived. This knowledge can then be used to estimate the reduction in flow capacity resulting from a blockage based on a single remote measurement

Accretion dynamics in the classical T Tauri star V2129 Oph

We analyze the photometric and spectroscopic variability of the classical T Tauri star V2129 Oph over several rotational cycles to test the dynamical predictions of magnetospheric accretion models. The photometric variability and the radial velocity variations in the photospheric lines can be explained by rotational modulation due to cold spots, while the radial velocity variations of the He I (5876 \AA) line and the veiling variability are due to hot spot rotational modulation. The hot and cold spots are located at high latitudes and about the same phase, but the hot spot is expected to sit at the chromospheric level, while the cold spot is at the photospheric level. Using the dipole+octupole magnetic-field configuration previously proposed in the literature for the system, we compute 3D MHD magnetospheric simulations of the star-disk system. We use the simulation's density, velocity and scaled temperature structures as input to a radiative transfer code, from which we calculate theoretical line profiles at all rotational phases. The theoretical profiles tend to be narrower than the observed ones, but the qualitative behavior and the observed rotational modulation of the H\alpha and H\beta emission lines are well reproduced by the theoretical profiles. The spectroscopic and photometric variability observed in V2129 Oph support the general predictions of complex magnetospheric accretion models with non-axisymmetric, multipolar fields.Comment: Accepted by Astronomy and Astrophysic

Application of nanoadditives for wear resistance improvement of parquet protective and decorative coatings

This article presents one of the promising ways of wear resistance improvement of nanoadditives modification coatings. The protective and decorative coating, composed of nanoadditives, was used to make samples. Testing samples showed that the use of nanoadditives improves coating operational characteristics, or wear resistance in this case. The dependence of wear resistance coatings on the flow nanoadditives was studied

Winter rye (Secale cereale L.) antioxidant capacity, total phenolic content and quality indices

Rye (Secale cereale L.) grain is an excellent raw material for healthy and tasty foods. Rye products are characterized by their unique composition and properties such as antioxidant capacity and total phenolic. The aim of the study was to assess radical scavenging capacity, total phenolic content, protein, starch content and falling number in rye varieties wholemeal. The trial included population winter rye varieties ‘Kaupo’, ‘Amilo’, ‘Dankowskie Amber’, ‘Dankowskie Rubin’, ‘Inspector’ and hybrid rye varieties ‘SU Drive’, ‘SU Mephisto’, ‘SU Bendix’, ‘Brasetto’, ‘Palazzo’ grown in Latvia. The antioxidant activity was determined using the DPPH (2.2-diphenyl-1-1-picrylhydrazyl radical) assay and total phenolic content was determined spectrophotometrically according to the Folin-Ciocalteou method. The rye grain antioxidant capacity was estimated as Trolox equivalent, while the total phenolic content was expressed as gallic equivalents (GAE). ‘Su Drive’ rye variety contained the largest amount of total phenolic (average 208 mg GAE 100 g -1 DW), but the lowest – ‘Inspector’ rye variety 176 mg GAE 100 g -1 DW. In general, all rye samples tested in this study demonstrated similar level of antioxidant capacity (from 38.5 to 46.2 mmol Trolox eq. 100 g -1 ). Statistically higher (P < 0.05) total phenols content and falling number had hybrid rye grains, compared to the population rye grains. In the present trial, the differences between hybrid varieties grains protein and starch content comparing to population varieties were not observed
