O FUTURO DA ESCOLA: UMA ETNOGRAFIA SOBRE A RELAÇÃO DOS JOVENS COM O CONHECIMENTO ESCOLAR
Authors: Borges Luís Paulo Cruz 
Published: January 2019

A presente tese tem como objeto de estudo a relação dos jovens estudantes do Ensino Médio com o conhecimento escolar. Pauta-se na abordagem teórico-metodológica etnográfica, situada na fronteira entre a antropologia e a educação. Assim, foram utilizados o caderno de campo, notas etnográficas, descrição densa, entrevistas, fotografias, observação participante e produções textuais como formas de apreender um recorte da realidade social. Articulam-se as categorias conhecimento escolar, juventudes e futuro, privilegiando os teóricos Bernard Charlot, Carmen Gabriel, Alice Lopes e Elizabeth Macedo, Juarez Dayrell, José Pais, Gilberto Velho, Clifford Geertz, Carmen de Mattos, Homi Bhabha, W. Pinar e Arjun Appadurai. A tese questionou: como jovens estudantes do Ensino Médio de uma escola pública da rede estadual do Rio de Janeiro se relacionam com o conhecimento socializado pela escola? Como objetivo geral, estudou e investigou, através da ótica dos próprios participantes da pesquisa, qual é o papel da escola diante do conhecimento escolar. Dessa forma, emergiram três categorias analíticas: i) o conhecimento escolar, partindo da relação entre as instâncias críticas e pós-críticas, colocando em xeque as concepções de escola e suas contradições presentes na modernidade, além de um confronto entre o texto curricular proposto na Base Nacional Curricular Comum (BNCC) com as vozes discentes encontradas na pesquisa; ii) a ideia de juventudes em trânsito abordando a relação dos jovens com o conhecimento escolar, compreendendo os processos educacionais e a própria imagem e concepção de juventude em sua relação com a escola. Opera-se numa lógica de que há uma polifonia nas vozes discentes que podem ser escutadas como forma de uma produção curricular pensando os dissensos como caminhos possíveis. iii) por fim, articula-se a categoria futuro da escola, e dos seus sujeitos, em um processo de dupla transitividade: o futuro como temporalidade e o futuro como emergência e (re)imaginação das relações sociais dos jovens com o conhecimento e a escola. Deste modo, trabalha-se o futuro como uma categoria etnográfica sob rasura, em que as vozes discentes indicam que escola e que conhecimento hão de existir. À guisa de conclusão, defende-se a tese de que o conhecimento escolar, entendido como atos de significação, é uma dimensão criadora dos modos de subjetivação e diferença, capaz de permitir a emergência de transformações sociais no contexto escolar que ocorrem a partir das vozes dos seus sujeitos pautando-se na enunciação cultural. Descrevem-se as vozes de alunos e alunas que se misturam à interpretação do pesquisador (re)imaginando a escola do futuro, que só se faz existente a partir de mudanças profundas em sua arquitetura moderna, a partir da sua reconstrução, sob rasura, e inserção na pós-modernidade.

The potential of modernization transformations of the Russian macroregion: a case study of the Central Black Earth region
Authors: Kogay Evgeniya A. 
Published: January 2019

The article raises the problem of socio-cultural modernization in a Russian macroregion - the Central Black Earth region. The author focuses attention on unevenness and discrepancy in the modernization processes. Based on results of the field studies, the paper describes opportunities and barriers to the implementation of modernization transformations in the macroregion. The structure of modernization potential is shown through reformatory, socially innovative and adaptive potentials. The reformatory potential of modernization is considered as low; the socially innovative potential as ambivalent; and the adaptive potential manifests itself through social wellbeing. Regional communities are characterized by the dissonance between the declared and the actual state of affairs, between inertial practices of social institutions and socio-cultural challenges of the present day. The author concludes that strategic management of development is important to optimize modernization processes in regional communities. The article also notes that active support of the inhabitants of the regions is also essential to successful implementation of modernization.

Published: January 2019

Latar Belakang : Salah satu faktor risiko timbulnya kejadian obesitas adalah adanya stunted. Gangguan pertumbuhan pada individu yang stunted menyebabkan berkurangnya jumlah dan kualitas sel serta jaringan organ internal, salah satunya adalah gangguan dari sistem endokrin. Gangguan sistem endokrin berdampak pada proses oksidasi lemak sehingga menyebabkan penumpukan jaringan adiposa berlebihan. Timbunan jaringan adiposa ini memicu timbulnya reaksi inflamasi yang salah satunya ditandai dengan peningkatan kadar High Sensitive C-Reactive Protein (hsCRP). Tujuan penelitian ini adalah membuktikan perbedaan kadar hsCRP antara kelompok stunted obesity dengan kelompok non-stunted-obesity.Metode : Penelitian cross sectional ini dilakukan di SMA Kota Semarang dengan pembagian wilayah berdasarkan kategori urban dan suburban secara classified cluster random sampling. Sampel terdiri dari 22 subjek stunted obesity dan 22 subjek non-stunted obesity. Obesitas ditentukan dengan perhitungan IMT/U > persentil ke-95 dan lingkar pinggang > 80 cm (perempuan) >90 (laki-laki). Stunted ditentukan dengan TB/U ≤ -2 SD sedangkan non-stunted ditentukan dengan TB/U>-2SD. Pengukuran kadar hsCRP menggunakan metode ELISA. Perbedaan kadar hsCRP antara 2 kelompok diuji dengan independent t-test.Hasil : Rerata kadar hsCRP pada kelompok stunted obesity adalah 4,51 mg/l sedangkan kelompok non-stunted obesity adalah 4,05 mg/l (p=0,665). Kategori tingkat inflamasi tinggi pada stunted obesity sebesar 50% dan non-stunted Obesity sebesar 40,9%.Simpulan : Kadar hsCRP kelompok stunted obesity terbukti lebih tinggi dibandingkan kelompok non-stunted obesity, tetapi secara statistik tidak bermakna.

Neuromodulation of early sensory processing in the olfactory system
Authors: Brunert Daniela , Rothermel Markus 
Published: January 2019

Zusammenfassung
In jedem Moment sind wir von einer Vielzahl von Informationen umgeben, die gleichzeitig von mehreren Sinnen empfangen werden. Eine enorme Menge an Daten muss daher in unserem Gehirn gleichzeitig verarbeitet werden, um unsere Umwelt richtig zu verstehen. Eine Anpassung der sensorischen Verarbeitung ist wichtig, um unsere Wahrnehmung kontextabhängig optimieren zu können, d. h. um adäquate Verhaltensreaktionen zu ermöglichen, muss eine effiziente sensorische Verarbeitung relevanter Stimuli gefördert und unwichtige Signale unterdrückt werden. Die zugrundeliegenden Mechanismen der sensorischen Informationsmodulation sind, insbesondere in frühen sensorischen Schaltkreisen, weitgehend unbekannt. Die Fähigkeit, diese Prozesse selektiv manipulieren zu können, wäre sowohl für die Grundlagenforschung als auch die translationale biomedizinische Forschung von großem Vorteil. Hier betrachten wir das olfaktorische System der Vertebraten als Modellsystem für die Untersuchung früher sensorische Verarbeitung und demonstrieren die Komplexität neuromodulatorischer Vorgänge anhand dieses Systems.
Thermal Expansion Studies of Carbon Nanotube-Reinforced Silver Nanocomposite
Authors: Kumar Dinesh , Nain Sonia , Kumar Ravi , Pal Hemant 
Published: January 2019

Abstract
In the present study, a simple and highly effective physical mixing method was used to synthesise carbon nanotube (CNT)-reinforced silver nanocomposites. Composites were prepared with different contents (vol%) of functionalised multiwall nanotubes. The microstructure of synthesised nanocomposites was analysed by X-ray diffraction, electron diffraction spectroscopy, and scanning electron microscopy. Microstructural characterisations revealed good distribution of nanotubes in the silver matrix. The thermal expansion behaviour of the composites was studied in reference to the variation in nanotube volume content in the silver matrix. It was observed that the coefficient of thermal expansion decreased with the increase in the percentage of CNT volume. The thermal expansion of the CNT-reinforced silver composites decreased to 55 % of pure silver upon the introduction of 6 vol% of nanotubes into the silver matrix. The thermal expansion behaviour of the CNT-reinforced silver composites was also analysed theoretically using the rule of mixture and Schapery’s model. The CNT-reinforced silver composites may be a promising contact and thermal management material in electronic devices.
Incompressible-Fluid Symbolic Computation and Bäcklund Transformation: (3+1)-Dimensional Variable-Coefficient Boiti–Leon–Manna–Pempinelli Model
Authors: Gao Xin-Yi 
Published: January 2019

Abstract
Incompressible fluids are of current interest. Considering a (3+1)-dimensional variable-coefficient Boiti–Leon–Manna–Pempinelli model for an incompressible fluid, we perform symbolic computation to work out a variable-coefficient-dependent auto-Bäcklund transformation, along with two variable-coefficient-dependent classes of the shock-wave-type solutions. Our auto-Bäcklund transformation is different from the recently reported bilinear one.

Published: January 2019

Abstract
Present study deals with use of agricultural based waste material Loquat (Eriobotrya japonica) seeds for removal of toxic Acid orange 7 (AO7) dye from aqueous streams. Batch mode experiments were conducted as function of pH, initial dye concentration, contact time and dosage of adsorbent. Biomass was used in native, pretreated and immobilized forms. Maximum removal was observed at pH 2. Desorption studies were done in order to determine degree of stability and regeneration of immobilized biomass. For equilibrium studies, Langmuir and Freundlich models were applied. Pseudo 1st & 2nd order models were applied on experimental data for reaction kinetics evaluation. Pseudo 2nd order model was best fit for present experiments. Biomass characterization was done by scanning electron microscopy (SEM), Energy dispersive X-ray (EDX) and Fourier Transform Infrared (FTIR) techniques for elucidation of biomass constituents and surface morphology before and after dye loading. It was observed that loquat seeds may be potential adsorbent for removal of toxic dyes from wastewater.

Published: January 2019

Abstract
The nanoparticles have been prepared and employed as excellent adsorbents for the sequestration of heavy metal ions and hazardous impurities from the aqueous media. The surface morphological, textural and structural properties of nanoparticles have been modified, which are capable and potentially useful for the remediation of metal ions. Several metals (oxides, doped, nanocomposites of Fe, Ti, Zn, SiO2, SiC, Mo, Co, Ni, Zr, Mn, Si, S, Al, Cu, Ce, graphene, CNTs) were reported an efficient adsorbents for the removal of lead (Pb) ions from aqueous media and polluted water. The present review focuses on different kinds of nanoparticles such as metal oxides, carbon based and host supported employed for removal of Pb ions under varying experimental conditions such as pH, temperature, contact time and concentrations. The preparation strategies, physicochemical properties and adsorption are also discussed. Based on studies, it was found that the smart materials are affective adsorbents for the purification of wastewater containing Pb ions and could possibly extended for the remediation of other heavy metal ions.

Published: January 2019

Abstract
The development of biocompatible, cost effective and more efficient materials to control or inhibit the growth of microorganisms in necessary to fight against resistant microbes. Here, we demonstrate the synthesis of nickel oxide-incorporated polyaniline/polyvinyl alcohol (PANI/PVA/NiOx) composite material by single-step polymerization and its application as antibacterial agent. The composite films were characterized using UV-visible spectroscopy (UV-Vis), Thermogravimetric analysis (TGA), Fourier Transform Infrared spectroscopy (FTIR), X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). UV-Vis spectra revealed the enhancement in absorption properties of PANI/PVA/NiOx with optimum 5% incorporation of NiOx. TGA results indicated slightly enhanced thermal stability of the PANI/PVA/NiOx composite film as compared to PANI/PVA. FTIR spectra for composites revealed the existence of NiOx in polymers. However the crystallinity of PANI/PVA was not much affected. The antibacterial activity of the prepared composites was examined against four different gram negative bacteria, Salmonella, Shigella, Pseudomonas and Escherichia coli (E. coli). The composite exhibited excellent antibacterial activity against E. coli, Salmonella and Shigella while pseudomonas showed some resistance. Based on the results, PANI/PVA/ NiOx (5%) composite showed the highest activity against the tested bacterial strains, thus showing its potential to be used as an effective antibacterial agent.
Politinių skandalų dinamika mediatizuotoje Lietuvos viešojoje erdvėje
Authors: Masiokaitė-Liubinienė Austėja 
Published: January 2019

[full article and abstract in Lithuanian; abstract in English]
The concept of mediatization, which analyzes how the dominance of media shapes political processes, is becoming continuously more relevant as a more important role is being assigned to the media in the public sphere. Despite the relevance, there are not many defined methods of analysis of political mediatization. This article presents such a method, which is designed for analyzing political scandals. This method adopts the concept of mediatization as a metatheory and uses the Veto Players theory to structure the political sphere and scandals in a way that allows for their analysis.
A qualitative content analysis of three cases of Lithuanian political scandals, based on this method, is also presented.
In the discussed cases, the interaction between the political and media actors appears to be very close and mutual. Not only do politicians take the initiative in asking for the political responsibility of the actors in the scandalous situations that the media reveal, but they also initiate the distribution of such information to the media, seeking the desired change of the status quo or the legitimization of their decisions. This provides means for talking about the self-mediatization of political actors.
