Published: April 2017

RESUMO: Argumenta-se nesse artigo que o Plano Nacional de Educao (PNE), por demandar um grande volume de recursos financeiros, enfrenta dificuldades para sua implementao e execuo. Em atendimento Constituio Federal, no seu art. 214 e LDB/96, no seu art. 9, inciso I, o PNE, foi aprovado em 2014, requerendo um aporte financeiro extra de grande magnitude, quando o petrleo era vendido a US$100 o barril e dava ao Pr-sal o papel de reserva financeira da educao. O barril de petrleo perdeu valor no mercado e a garantia de aporte extra para a educao tornou-se distante. Pior ainda, o pas apresentou, em 2014, dficit nominal em suas contas pblicas!--[if !supportFootnotes]--[i]!--[endif]--. Dificilmente haver recursos pblicos para cobrir os novos investimentos na educao, que j alcanam R$158,3 bilhes e iriam para R$336,2 bilhes com o PNE, aumentando R$177,9 bilhes.

Este artigo possui o objetivo de examinar o novo Plano Nacional de Educao PNE (Lei 13.005/2014), enfatizando o carter que a referida Lei emprega s avaliaes externas em larga escala e qualidade educacional. A partir da anlise realizada foi possvel constatar que o novo PNE apresenta um vis marcado por entendimentos de carter mercadolgico (assentados na ideologia neoliberal), que atrela a qualidade educacional a ndices pr-estabelecidos (como, por exemplo, o ndice de Desenvolvimento da Educao Bsica IDEB), restringindo o conceito de qualidade educacional a resultados e produtos (quantitativos), desconsiderando os processos, alm de ampliar a noo de educao pblica. Diante das discusses suscitadas pela lei analisada, aponta-se para outra concepo de qualidade educacional, a qualidade social, pautada na construo coletiva (participativa) em defesa da educao como um direito social que possibilita a emancipao humana.

Under the conditions which are characteristic for electron cigarette usage chemicals containing in cigarettes (nicotine (0-2% weight usually), propylene glycol, glycerol, distilled water and different flavors) are capable to thermal decomposing and the products of decomposition could react with each other. Thus, harmful compounds and carcinogens may evolve. Literature describes a number of experiments detecting the formation of tobacco-specific nitrosamines, diacetyl and acetyl propionyl, toluene, ethyl benzene, o-, m-, p-xylene, formaldehyde, acetaldehyde, acetone, propenal, glyoxal.The present contribution describes our efforts to study the composition of vapors over the liquids for electronic cigarettes containing no flavors by means of IR-spectroscopy. The temperature range was 20 to 400 °C, and flow of air and argon was used. The electronic cigarette liquid was found to emit aqueous vapor, carbon dioxide, propylene glycol and glycerol mostly. Propenal was also detected in vapors in argon atmosphere at temperature of ~350 °C. No other compounds were found in neither liquid phase by 1H, 13C NMR spectroscopy after heating to 150 oC or vapors at temperature lower than 250 °C.Forcitation:Gamov G.A., Smirnov N.N., Aleksandriiskii V.V., Sharnin V.A.

Published: April 2017

In this article the electrochemical methods were developed for selenium separation from the lead admixtures in technical selenium which was obtained at the refining the anodic muds from Shchelkovo combinate at the use of nitro-acidic and sulfur-acidic electrolytes. At the optimal conditions of carrying out the electrolysis under using nitrogen acidic electrolytes almost all lead is precipitated on the anode and, accordingly, it is separated from selenium. Later, after separation of the main mass of lead, the precipitation of selenium on the cathode was carried out. According to technology proposed the electrolytic selenium of high purity degree (99.999%) was obtained at application of nitric solutions of electrolyte. The content of lead in the complex cathode-selenium was 1·10-4%. Under the optimal conditions of selenium precipitation from the hydrochloric acidic electrolytes, selenium was not found in the cathode sediments of lead. The admixtures of different elements (Te, Pb, Bi, Ag, Si and others) existing in technical selenium make worse its electrophysical properties very strongly. In order to obtain selenium with a high degree of purity, it is necessary to carry out the wide scientific investigations in the field of electrolytic purification of technical selenium.Forcitation:Mirzoyeva A.A., Bakhtiyarli I.B.

Published: April 2017

The paper considers the problems of obtaining the new electrode materials used in the electric power sources. The electrode material was prepared by anodic electrophoretic deposition in an alkaline medium of graphite nanosized particles. Nanoscale carbon phase was obtained by graphite foil anodic polarization in sulfuric acid followed by ultrasonic dispersing of the obtained powder. Electrophoretic coatings were deposited on a stainless steel electrode at applied potentials in the range of 5-10 V. The dependence of the anodic current density and specific capacity of the deposited film is linear on the anode potential. The method of FT-IR spectroscopy to study the properties of the surface of the obtained film was used. It was shown that as a result of electrophoresis the sufficiently strong reduction of surface oxygen-containing groups represented mainly phenolic groups occurs. The optimal value of the potential for deposition of electrophoretic films - 5 V, for a given value after 5 min of electrophoresis formed film thickness is 430 nm with a minimum content of oxygen-containing surface groups. Electrochemical properties of the resulting films were determined with a cyclic voltammetry in an acidic medium. It was found that at value of the potential sweep rate of 20 mV/s the specific film capacity was 117 F/g.Forcitation:Bratkov I.V., Yudina T.F., Mel'nikov A.G., Ershova T.V., Filimonov D.A.

4-(9-Hydroxy-1,4,7-trioxynonyl)phthalonitrile was prepared by reaction of 4-nitrophthalonitrile with triethylene glycol in dry DMSO in the presence of fresh-calcined fine milled K2CO3 at 60 °C for 12 hours. The reaction mixture was poured into cold distilled water and extracted by CH2Cl2. Then the crude product obtained after solvent evaporation was purified by column chromatography on silica gel using elution mixture of ethyl acetate : hexane (1:3) and after that end product was dried at reduced pressure at 80 oC for 4 h. The product was characterized by IR and 1Н NMR spectroscopies, mass-spectrometry, elemental analysis and X-ray diffraction data. In MALDI-TOF spectrum, two signals located at 299 [M+Na]+  and 315 [M+К]+ Da were detected. Conformity between the calculated isotopic distributions and those derived from experimental data proves these assignments. A colorless monocrystal suitable for X-Ray measurements was grown up by low temperature solvent evaporation from a solution of 4-(9-hydroxy-1,4,7-trioxynonyl)phthalonitrile in ethyl acetate. X-ray studying showed that this compound is a monohydrate of 4-(9-hydroxy-1,4,7-trioxynonil)phthalonitrile with a water molecule located in lateral chain. Four molecules of 4-(9-hydroxy-1,4,7-trioxynonil)phthalonitrile and four water molecules were founded to be located in one unit cell with formatting eight intermolecular hydrogen bonds. Hence triethylene glycol fragment forms a chelate-like cavity which is able to hold a water molecule or a cation of alkali metal. It was found that its structure is very similar to that optimized at DFT/B3LYP/6-31G(d,p) level. The some bond lengths of theoretical calculations are found to be greater than experiment data because of close intermolecular interactions in solid state.Forcitation:Kuznetsova A.S., Dmitriev M.V., Zav’yalov A.V., Koifman O.I., Islyaikin M.K.

Published: April 2017

The studies of the growth and development of higher plants of soybean and beans in a process of soil purification from ions of chromium (III) by the method of phytoremediation exposing phytoremediation plant seeds (soybean and beans) to UV - and IR-radiation were carried out. It was shown that the efficiency of cleaning up the soils polluted with ions of Cr3+, is 93 – 98 % and its value increased with metal concentration increasing. It is caused by the fact, that chromium is a trace element which is necessary for the growth and development of plants, and its concentration in biomass is controlled. Adsorption capacity (Ai) of plants toward chromium was determined. As metal concentration increased, Ai was increased and for soybean it was 80 h (126 µg/kg) of dry biomass after treating the seeds with UV - radiation, and 74 ч (91 µg/kg) after IR radiation. Adsorption capacity of beans Аi was lower in comparison with soybean and the maximum values did not exceed 55 ± 5 mkg/kg of dry biomass. The difference in Ai values after treating seeds with UV - and IR- radiation were insignificant.Forcitation:Olshanskaya L.N., Shevlyakov N.А., Bakanova Е.М.

CATALYTIC ACTION OF NITROGEN-CONTAINING BASES ON KINETICS OF ZINC AND HEXA- (m-TRIFLUOROMETHYLPHENYL)BENZOPORPHYRAZINE COMPLEX FORMATION
Authors: Petrov Oleg A. , Sadovskaya Irina N.
Published: April 2017

A complexation reaction of hexa(m-trifluoromethylphenyl)benzoporphyrazine with zinc acetate in the system “morpholine (piperidine) – benzene” was studied. Preliminary studies have shown that at concentrations of morpholine and piperidine in benzene less than 0.95 and 0.2 mol/l respectively, the reactions between hexa(m-trifluoromethylphenyl)benzoporphyrazine and zinc acetate not observed. The reaction takes place only at the range of concentrations of morpholine of 0.95 to 8.70 mol /l in benzene and at the range of concentrations of piperidine of 0.2 to 7.74 mol /l in benzene. The changes in the electronic absorption spectrum do not depend on the nature of the nitrogen-containing base, and accompanied by π - chromophore molecules from D2h to D4h symmetry increase. It was shown that complexation describes with the total kinetic equation of the third order. That is there is the first order on every reagent -hexa (m-trifluoromethylphenyl) benzoporphyrazine, zinc acetate and the base. A possible scheme of the mechanism in which the acid - base interaction of   hexa (m-trifluoromethylphenyl) benzoporphyrazine with morpholine (piperidine), leading to the H – complex formation is the rate-limiting step of the process proposed. This complex unlike molecular form posseses higher reactivity at interaction with zink cation since an expenditure of energy for breaking intracyclic NH bonds is essentially lower. It was found that rate of hexa (m-trifluoromethylphenyl) piperidin benzoporfirazina coordination by zinc is higher in system “piperidine – benzene”. At replacement of piperidine with morpholine рКа of bases decreases by a factor of about 2.5. It results in the decrease in complexation rate judging by values of k298  by a factor of ~7 on the background of constancy  of activation parameters of reaction. This fact is not surprising since less pronounced proton acceptor ability of morpholine complicates removal of intracyclic proton of NH - groups with formation of N - complex and, consequently, complicates zinc cation entrance into the coordination plane of the macrocycle.For citation:Petrov O.A., Sadovskaya I.N.

In this study, the degradation of Acid Orange 7 (AO7) in aqueous solutions by iron(III) under activation by persulfate (PS, S2O82-) oxidation and Visible (Vis) light (≥420 nm) exposure was performed. The efficiency of different systems including Fe3+/Vis, Fe3+/PS, PS/Vis and Fe3+/PS/Vis has been evaluated. It was found that the efficiency of Fe3+/PS and PS/Vis system was low, and only about 48% of AO7 was oxidized within 20 min of experiment time under Fe3+/Vis system action, and it was further improved to almost 95% within 20 min by Fe3+/PS/Vis system. Various process-dependent parameters, such as PS, Fe3+, dye concentration as well as initial pH were investigated to optimize the process. As results indicated, the dye's degradation efficiency increased with the increase of PS and Fe3+ concentration over the tested range. The pH had an insignificant effect on the degradation of AO7. The effect of inorganic anions was also investigated and the suppressive effects of inorganic anions can be ranked in an ascending order of Cl−≈NO3−<SO42−<HCO3−≈HPO42−.Forcitation:Heng Zhong, Jun Li, Hui Zhao, Lei Sun, Aihua Xu, Dongsheng Xia, Nevsky A.V.

PHOTODISSOCIATION DYNAMICS OF SPATIALLY ALIGNED MOLECULES BY TIME-RESOLVED ELECTRON DIFFRACTION
Authors: Schafer Lothar , Ischenko A.A. , Zhabanov Yu.A. , Otlyotov A.A. , Girichev G.V.
Published: April 2017

The anisotropic ensembles of laser-excited molecules can be formed, for example, under the action of fs pulses of polarized laser radiation. It was theoretically predicted that the electron diffraction pattern from aligned molecules in the gas phase allows determining not only internuclear distances but also valence angles that is 3D molecular structure. In the current article, we propose the basic elements of the theory that can be employed for analyze of time-resolved electron diffraction (TRED) data obtained from oriented/aligned laser-excited molecules. This formalism is applicable to dissociative processes and to nuclear dynamics studies of photo dissociation studies. The theory is illustrated by modeling the diffraction intensities of photo generated dissociation of ICN molecules. The time-dependent intensities of the molecular scattering and the corresponding radial distribution functions of the internuclear distances at the processes of the photo dissociation of ICN were calculated.Based on model calculations presented in this article we conclude that TRED method provides the principal possibility of study of coherent dissociation dynamics for real scale of time which is essentially less than the electron pulse duration of 300 fs, which is achieved at present in a number of TRED experiments. The results obtained were compared with our previous modeling studies of randomly oriented and diatomic aligned molecular ensembles.Forcitation:Schafer L., Ischenko A.A., Zhabanov Yu.A., Otlyotov A.A., Girichev G.V.

Introduction: School bullying is characterized by over time repetitiveness of aggression, by the intentional injuring or causing suffering to another, and by the imbalance of power between the participants. This is not a new phenomenon, because the recurring situation of violence between peers at school has probably been a regular feature throughout human history. Involvement in school bullying can have negative consequences, including for the students´ teaching-learning process, in which those involved may have troubles such as failing, dropping out, as well as episodes of indiscipline. Objective: Identify the school performance of children and adolescents in a socially vulnerable situation, as well as to analyse the possible relationships of this performance with participation in the situations of violence that characterize school bullying. Method: 375 primary school children and adolescents of both genders aged between 8 and 16 years participated in the study. The instruments used were School Performance Test, Sociometric Scale and, Questionnaire for the Study of Violence Among Peers. The data were analysed using ANOVA Two-way test and Spearman correlation. Results: The present study indicates that children and adolescents in a socially vulnerable situation had results that were below expectations with respect to school development and performance in the three subtests – writing, arithmetic, and reading – in both genders and in different age groups. In an intra and extra analysis group, there was a significant difference between female children and adolescents in all subtests. However, the same was not observed among boys. There was also a relationship between poor school performance and participation in bullying situations, in which it was found that the score on the writing subtest was negatively correlated with practicing aggression and witnessing violence at school. A similar result occurred in relation to the reading subtest. The arithmetic subtest score, in turn, correlated negatively with the three forms of participation in situations of school violence: to assault, suffer abuse, and witnessing violence against colleagues. Finally, the total score obtained in SPT negatively and significantly correlated with practicing aggression and witnessing violence. Conclusion: Based on the results of this study, it was found that most children and adolescents in a socially vulnerable condition showed a lower school performance level than expected for their year attending. Allied to these results, it was found that teenage girls showed better performance than children of the same gender did. Moreover, there is a relationship between poor school performance and participation in bullying situations in different roles: victim, bully, and bystander.

Introduction: In recent years, there has been a reduction in cases of malnutrition in Brazil but this has been accompanied with an increase in the overweight and obesity rates. These changes, together with others, such as changes in eating patterns and lifestyle, characterise the process of nutritional transition. Objective: We aimed to compare the prevalence of nutritional status of beneficiary children of the Bolsa Família Program (PBF) in the states of Acre and Rio Grande do Sul, Brazil, and to analyse the changes in the anthropometric profile of these children during 5 years. Methods: This is an ecological study using secondary data from the Food and Nutrition Surveillance System (SISVAN) and Bolsa Família Department of SUS (DATASUS), which assessed the nutritional status of children over 5 years and under 10 years benefiting from the PBF in the years 2011 to 2015 in the states of Acre and Rio Grande do Sul. The sample consisted of 94,865 children from Acre and 342,462 children from Rio Grande do Sul. The Body Mass Index was used to classify the nutritional status. Results: The mean prevalence of eutrophic children aged 5 to 10 years in Acre was 70.42% and was 61.28% in Rio Grande do Sul. Overweight was 13.06% in Acre and 19.48% in Rio Grande do Sul. Obesity was 5.08% in Acre and 9.36% in Rio Grande do Sul. Severe obesity was 4.02% in Acre and 6.92% in Rio Grande do Sul. Conclusion: Overweight and obesity in children benefiting from the PBF has been growing in the last 5 years, notably in the state of Rio Grande do Sul. This is possibly due to the fact that the nutritional transition is at a more advanced stage here than in Acre State.

Objective: To analyze the impact of basketball practice on bone mineral density of male adolescents. Methods: 9-month cohort study carried out with 27 adolescents (controls, n= 13 [11.9±2.2 years] and basketball players, n= 14 [13.4±1.2 years]). Bone mineral density was measured in different body segments (upper limbs, lower limbs, spine, and total) using the dual energy X-ray absorptiometry technique. Intake of vitamin D, chronological age, somatic maturation, fat-free mass, and height were adopted as confounders. The statistical analysis was composed of the Student's t-test, analysis of covariance, and Pearson/partial correlations. Results: Regardless of confounders, there was a positive relationship between higher basketball practice time and bone density gains in the upper limbs (r= 0487 [95%CI= 0.131 to 0.732]). Conclusion: The practice of basketball seems to affect bone mineral density gains in adolescents, mainly when the practice is prolonged.

Introduction: Physical capabilities are an important parameter of the functional development of adolescents, not only by chronological age but also by their maturational state, as individuals with the same chronological age can have different performance to their less mature counterparts. Objective: To compare and relate the physical capabilities and hormonal markers according to sex and maturity of adolescents. Method: The sample consisted of adolescents of both sexes, aged 10 to 14 years. We evaluated the maturity achieved by a predictive equation of skeletal age, physical capabilities (explosive power of upper and lower limbs, velocity of upper limbs and agility) and hormonal markers (testosterone and oestradiol) via chemiluminescence. Results: Females showed more advanced maturational status, higher weight, body height and oestradiol levels; males performed better in the explosive force of upper and lower limbs, upper limb speed, agility and testosterone levels. In the normal maturational state males showed greater skeletal age, body weight, body height, explosive strength of upper and lower limbs, and testosterone levels; the females in the normal maturational state had higher skeletal age, body weight, body height, explosive upper limb strength and oestradiol levels. In the male correlation analysis, bone age was related to the explosive strength of upper and lower limbs and testosterone; while bone age in females was related to explosive upper limb strength and oestradiol. Conclusion: It is concluded that maturation, testosterone and oestradiol levels play an important role in the physical aspects and performance of motor skills of adolescents, especially in upper limb force which was more related to the maturation obtained by skeletal age of males and females.

Published: April 2017

Introduction: Bronchopulmonary dysplasia (BPD) is a multifactorial chronic lung disease that contributes to disruption of pulmonary development. It may impair   pulmonary function in early childhood and persist throughout school-age, adolescence, and into adulthood. Objective: To analyze, through a systematic review, the impact of BPD on pulmonary function in early childhood. Methods: Systematic searches were performed in three electronic databases (Medline, SciELO and PEDro). Two independent examiners analyzed the titles, abstracts and full texts, considering the following study inclusion criteria: studies of pulmonary function in up to 5-year-old children diagnosed with BPD in the neonatal period. Results: Initially, 1789 articles were identified, and the final sample included 22 articles. It could be observed that children diagnosed with BPD in early childhood showed expiratory flow limitation and reduced functional residual capacity. However, pulmonary function in children with a history of BPD remains reduced when compared with healthy full-term children. Moreover, there are no positive responses in pulmonary function values with the use of bronchodilators. Conclusion: Children with BPD show changes in pulmonary function, which may improve with growth, and most of them do not respond positively to bronchodilators.
