The Current State of Special Needs Education in Russia: Inclusive Policies and Practices

AbstractModern educational system in Russia fully takes in only those who meet its specific requirements, i.e. those who can study on the program equal to everyone and thus those who can show expected progress. And the result is that children with special educational needs are often isolated from their healthy peers and drop out of the total educational process. Inclusive education is the way to settle this problem. This article focuses on inclusive education, providing an overview of the developments of inclusive education in Russia. The challenges and progress are being discussed as well as the main trends in policies and practices

Economics of boar taint prevention without surgical castration in the pork chain

An economic analyses of boar taint prevention without surgical castration is lacking. This paper explores currently feasible alternatives to surgical castration along the pork chain. The considered alternatives include genetic selection (pig breeding stage); altering management strategies (pig growing stage); slaughter at younger age and lower weight (slaughtering stage). Control measures relevant to these alternatives were designed and examined, using costeffectiveness and cost-benefit analysis. Results show that the option of single-sex raising of entire males is more cost-effective compared to the mixed-sex option. The breeding programs combining selection on boar taint and economics are more cost-effective than programs focusing on boar taint only, and also much more cost-effective than slaughtering at a younger age and lower weigh

In situ study of the temperature stability of TiO1.05 titanium monooxide using synchrotron radiation

The temperature stability of cubic TiO1.05 titanium monooxide is investigated. An in situ X-ray structural analysis is performed using synchrotron radiation in a high temperature vacuum chamber. It is found that under poor vacuum and at high heating rates of up to 1250 C, the structural transformations in TiO1.05 occur at 630 C. In particular, there is a phase transition from TiO1.05 (space group Fm-3m) to rhombohedraic Ti2O3 (space group R-3c) via Ti2.5O3 (space group Immm). © 2013 Allerton Press, Inc

Positron annihilation sites in nano lead sulfide powders

The coincident Doppler broadening of the positron-electron annihilation radiation has been applied for the identification of vacancies in nano lead sulfide (nano-PbS) powders. The results of the positron annihilation studies on nano-PbS with different particle size are presented. Nano-PbS specimens have been synthesized by the chemical bath deposition in aqueous medium. Independently of the size of nanoparticles (from 12 to 16 nm) the positron lifetime (PLT) for all specimens has been found to be the same and equal to 391±1 ps. Independently of the size of nanoparticles the chemical surrounding of positron annihilation sites identified by coincident Doppler broadening measurements was the same, namely lead (Pb).Canberra;Orte

Sol-Gel Synthesis of Nonstoichiometric Titanium Dioxide for Photo-Oxidation of Toxic Organic Substances

Titanium dioxide (TiO2) was synthesized by sol-gel method at different values of pH = 3, 7, 8, 9, or 10. X-ray phase analysis has shown that in an acid rout, an anatase phase had crystallized, and in an alkaline rout an amorphous phase of TiO2 was achieved. After annealing for 4 hours at 350∘C, all samples were transformed into anatase phase. The particle size in the different samples varies from 7 to 50 nm depending on the pH. The diffuse reflectance spectra revealed a high value of the band gap width in the range from 2.9 to 3.4 eV and its narrowing after annealing to the range from 2.8to 3.1 eV. The specific surface area measured by BET method was changing from 80 up to 140 m2 /g. Keywords: Titanium dioxide, nanostructure, photocatalysis, band gap, specific surface are

Disintegration of microcrystalline Zn2SiO4:Mn phosphor powder

Zn2SiO4:Mn (willemite) nanoparticles ∼30 nm in size have been prepared by disintegrating microcrystalline willemite powder in a planetary ball mill. X-ray diffraction and scanning electron micros-copy characterization showed that ball milling of the Zn2SiO 4:Mn powder for 60 min or a longer time ensured complete disintegration of the microcrystalline material and that the crystal structure of the resultant nanoparticles was identical to that of the parent powder. © 2013 Pleiades Publishing, Ltd

Synthesis and Attestation of Titanium Dioxide Nanotubes Based Photocatalyst for Water and Air Purification out of Harmful Organic Impurities

In the present work we have synthesized nanotubular TiO2 film with a nonstoichiometric layer in the vicinity of titanium foil by anodization during 120 min. The catalytic activity of nanotubular titanium dioxide films formed during the oxidation of acetone to carbon dioxide under the action of visible light with a wavelength of 450 nm was found to be approximately 2 times higher compared to standard titanium dioxide (Degussa P25). Such a pronounced enhancement of activity may be attributed to a more efficient absorption of visible light by the films due to narrowing of the optical gap because of difference in the nonstoichiometry of titanium dioxide near the interface between nanotubular film and the titanium foil substrate. Keywords: photocatalysis, nonstoichiometric titanium dioxide, purification of wate

Consumers' Perception of Milk Safety

Several times during the last decade consumers have been warned about different incidents concerning food safety, like, salmonella in eggs, cheese and poultry, and pesticides residues in tomatoes. The problem of food safety is still to be a largely latent concern for consumers. The main research goal of this paper is to investigate consumers' risk attitudes and risk perceptions concerning milk safety and to estimate their willingness to pay for extra-safe milk. The data was collected in the Netherlands using a mail survey. 211 usable questionnaires (26%) were returned. Results show that, in general, consumers are not concerned about the safety of milk. However, the results of consumers' perceptions of the "riskiness of milk contamination" for vulnerable groups of people show that babies are considered to be more sensitive to different sources of contamination than other groups. This study supports the results of previous food safety studies showed that consumers are willing to pay a price premium to the traditional purchase price to avoid some perceived risks. 58% of respondents are willing to pay an additional price for extra-safe milk. The conjoint experiment results indicate that the most important factors for consumers' preference are risk of contamination and presence of a label. Based on a conjoint analysis four segments of respondents were distinguished: "Balanced Shoppers"; "Safety-Seekers"; "Safety-Indifferent"; and "Extreme-Safety Seekers".food safety, questionnaire survey, risk attitudes, risk perceptions, willingness to pay, willingness to buy., Food Consumption/Nutrition/Food Safety,

Role of structural vacancies in the stabilization of the basic B1 structure in nonstoichiometric titanium monoxide TiO y

The electron structures and formation enthalpies of vacancy-free cubic TiO, vacancy-ordered monoclinic Ti5O5, and vacancy-disordered cubic TiO y have been investigated using DFT+GGA calculations. Ti5O5 was found to be the stablest phase and TiO was found to be the least stable. The reason for the stability of the titanium and oxygen vacancies in the basic B1 structures of Ti5O5 and TiO y has been deduced. The titanium vacancies lead to a decrease in the Fermi energy. Oxygen vacancies cause strengthening in covalent Ti-Ti bonding. © 2013 Allerton Press, Inc

Periods of academic mobility development in Russia

© 2016 Shakirova & Valeeva.Every year the number of students participating in the mobility programs grows rapidly. This is the main reason of the scientific interest to the problem of academic mobility. In spite of the fact that academic mobility has recently become the subject of study of many researchers, the phenomenon of academic mobility is not a new one. By present time some Russian and foreign researchers have devoted their studies to the problem of the academic mobility periodization. However, most of them cover mostly the XX and XXI centuries. Nevertheless, it does not mean that academic mobility had not existed before that period. Some researchers support the opinion that the beginnings of academic mobility can be found in the Medieval Times. There is a small amount of scientific works devoted to the problem of academic mobility periodization. The analysis of these works is of great importance, as there is no universal variant of academic mobility periodization
