Analizamos el valor de la pulsión escópica en la acción ambivalente del ver: extromisión e intromisión. Poniendo de relieve que la pantalla implícita de nuestras imágenes se desvela por nuestra visión en la confrontación con lo real, tal como la historiografía moderna enseña desde sus teorías y dispositivos de ver y representación, verificando esa confrontación por el triunfo del trompe l´eoil y la simulación. La complejidad del relato productivo técnico de las imágenes recoge la artificialidad argumentando tanto objetividad como efusión de imagen, connivencia científica como fantasma, desde el anamorfismo a los dispositivos mecánicos como giros históricos significativos.
New Wars and Their Visual Representation: Dead Bodies without Graves/Mourne
Authors: Şur Tuncay , Yarar Betül
Published: November 2020

This paper seeks to understand why there has been an increase in photographic images exposing military violence or displaying bodies killed by military forces and how they can freely circulate in the public without being censored or kept hidden. In other words, it aims to analyze this particular issue as a symptom of the emergence of new wars and a new regime of their visual representation. Within this framework, it attempts to relate two kinds of literature that are namely the history of war and war photography with the bridge of theoretical discussions on the real, its photographic representation, power, and violence.  Rather than systematic empirical analysis, the paper is based on a theoretical attempt which is reflected on some socio-political observations in the Middle East where there has been ongoing wars or new wars. The core discussion of the paper is supported by a brief analysis of some illustrative photographic images that are served through the social media under the circumstances of war for instance in Turkey between Turkish military troops and the Kurdish militants. The paper concludes that in line with the process of dissolution/transformation of the old nation-state formations and globalization, the mechanism and mode of power have also transformed to the extent that it resulted in the emergence of new wars. This is one dynamic that we need to recognize in relation to the above-mentioned question, the other is the impact of social media in not only delivering but also receiving war photographies. Today these changes have led the emergence of new machinery of power in which the old modern visual/photographic techniques of representing wars without human beings, torture, and violence through censorship began to be employed alongside medieval power techniques of a visual exhibition of tortures and violence.
Albrecht Dürer And The 16th Century Melancholy
Authors: Rodrigues Marcel Henrique
Published: November 2020

Little has been discussed in academia about the close relationship between the Renaissance of the 16th century and melancholy humor, and esoteric elements arising mainly from Florentine Neoplatonism. The link between melancholy and esotericism becomes very clear when we analyze the gravure “Melencolia I” by Albrecht Dürer (1471-1528), composed of a significant number of symbols that refer to an esoteric religious culture that then emerged. Renaissance melancholy gained several nuances. On the one hand, it was considered a sin, a despicable mood characteristic of witches; on the other hand, a deep sense of inspiration typical of men of “genius”. This ambivalence also occurred in the firmament, as the melancholic people were guided by the dark planet Saturn, according to astrological belief. We also have the cultural scenario of the 16th century, especially in Dürer's Germany, which contributed to strengthening the melancholy issues.

A bimodal extension of the Eriksen flanker task
Authors: Ulrich Rolf , Prislan Laura , Miller Jeff
Published: November 2020

The Eriksen flanker task is a traditional conflict paradigm for studying the influence of task-irrelevant information on the processing of task-relevant information. In this task, participants are asked to respond to a visual target item (e.g., a letter) that is flanked by task-irrelevant items (e.g., also letters). Responses are typically faster and more accurate when the task-irrelevant information is response-congruent with the visual target than when it is incongruent. Several researchers have attributed the starting point of this flanker effect to poor selective filtering at a perceptual level (e.g., spotlight models), which subsequently produces response competition at post-perceptual stages. The present study examined whether a flanker-like effect could also be established within a bimodal analog of the flanker task with auditory irrelevant letters and visual target letters, which must be processed along different processing routes. The results of two experiments revealed that a flanker-like effect is also present with bimodal stimuli. In contrast to the unimodal flanker task, however, the effect only emerged when flankers and targets shared the same letter name, but not when they were different letters mapped onto the same response. We conclude that the auditory flankers can influence the time needed to recognize visual targets but do not directly activate their associated responses.
Seebeck coefficient of silicon nanowire forests doped by thermal diffusion
Authors: Elyamny Shaimaa , Dimaggio Elisabetta , Pennelli Giovanni
Published: November 2020

Thermoelectric generators made by large arrays of nanowires perpendicular to a silicon substrate, that is, so-called silicon nanowire forests are fabricated on large areas by an inexpensive metal-assisted etching technique. After fabrication, a thermal diffusion process is used for doping the nanowire forest with phosphorous. A suitable experimental technique has been developed for the measurement of the Seebeck coefficient under static conditions, and results are reported for different doping parameters. These results are in good agreement with numerical simulations of the doping process applied to silicon nanowires. These devices, based on doped nanowire forests, offer a possible route for the exploitation of the high power factor of silicon, which, combined with the very low thermal conductivity of nanostructures, will yield a high efficiency of the conversion of thermal to electrical energy.

READING CULTURE IN POSTMODERN NARRATIVES
Authors: Bharvad Rajesh
Published: November 2020

Postmodernism evolve from various cultural contexts and it is not independent of
cultures but rather a direct representation of cultures. It is pertinent to note that all the
narrative strategies in postmodern literature represent the cultural changes. In other
words, fragmentation in postmodern literature is nothing but a reflection of fragmented
culture. With its widespread influence, postmodern narrative strategies have been
adapted in various cultures and locations. The fiction becomes an amalgamation of
plural narrative patterns that correspondingly work to inscribe and dismantle the existing
fundamentals. There are no fixed criteria to assign specific boundaries among various
narrative strategies; they intersect each other indispensably.
Subversion of the metanarratives has led to pluralism and multiplicity, and it creates an
environment of polyphony in the postmodern novel. The postmodern problem with
metanarratives creates a natural scope for multiple narrative patterns in the fiction. In
other words, all the strategies are parts of the postmodern plurality, and they
inescapably rely on each other. For instance, in a magic realist text, apart from having
magic realism as a key narrative strategy, other narrative strategies such as parodical
inversions, playfulness, Bakhtinian carnivalesque, and postmodern historiography also
coexist in the culture of pluralism. Hence, the research paper investigates how narrative
strategies in postmodern literature are foregrounded in various cultural contexts, and
their meanings exist in the cultures itself.
THE DESTINED MEETING PLACE OF SAVITRI AND SATYAVAN IN SRI
AUROBINDO’S SAVITRI
Authors: Brahmbhatt Shaurya
Published: November 2020

Sri Aurobindo is one of the foremost writers in the field of Indian writing in English in general
and Indo-Anglian drama in particular. He is an institution in himself; he was a great patriot, the
fiery evangelist of Nationalism, a great scholar, the interpreter of the Veda, Upnishadas and
The Geeta, the critic of life and literature. Here we consider him as a man of letters in Excelsis,
a master of prose art, and a dramatist and poet of great power and adaptability. With his
wonderful mastery over languages like English, Sanskrit and Bengali, “Sri Aurobindo produces
in one the impression that he is a born lord of language.” All his writings bear testimony to his
genius and knowledge of the Eastern and the Western thought. This research paper is
focusing on his poetic skills on describing the beauty of meeting of twin souls, being a yogi
how wonderfully he painted a beautiful picture of love and its meeting, Satyavan and Savitri
meet each other in the forest in where there is a cool and sensible breeze in the air of spring
and the love of them groves. Reading this destined meeting of Satyavan and Savitri defiantly
leads us into the different word where Shree Ram meets Seeta and Shree Krishna to Radha.

This research aims to study the effect of pulsating frequency on flame structure and heat transfer characteristics of premixed flame from a pipe nozzle. The LPG and air were used as gas fuel and oxidizer. The equivalence ratios ( ) were evaluated at 0.8, 1.0, and 1.2 under a constant Reynolds number Re = 500. The effect of nozzle-to-impingement surface distance ratio was investigated at H = 2D to 10D, here D is the nozzle diameter at 12 mm. The frequency of pulsating (f) was varied from f = 0 to 10 Hz using a solenoid valve. The flame structures of free flame jet and the impinging flame jet were recorded with a digital camera. The average heat flux on impingement surface was measured with water cooling plate and evaluated from the heat balance of the cooling water. The results show that the pulsating of flame jet become having gap on flame and the mushroom appear at the end of flame. The size of mushroom structure becomes larger when increasing the frequency. While the non-pulsating jet did not appear in this structure. Pulsating flame jet can increase the overall average heat flux on the impingement surface up to about 12% for case of = 1.2 and H = 2D and f = 10 Hz. when compared to case of f = 0 Hz.

Published: November 2020

Jet impingement has been applied for internal cooling in gas turbine blades. In this study, heat transfer characteristics of impinging jets from a row of circular orifices were investigated inside a flow channel with rotations. The Reynolds number (Re) based on the jet mean velocity was fixed at 6,700. Whereas, the rotation number (Ro) of a channel was varied from 0 to 0.0099. The jet-to-impingement distance ratio (L/Dj) and jet pitch ratio (P/Dj) were respective 2 and 4, Dj is a jet diameter of 5 mm. The thermochromic liquid crystals (TLCs) technique was used to measure the heat transfer coefficient distributions on an impingement surface. The results show that heat transfer enhancement on a jet impingement surface depended on the effects of crossflow and Coriolis force. The local Nusselt number at X/Dj?20 on the leading side (LS) was higher than on the trailing side (TS) while heat transfer on the LS at 20?X/Dj?40 gained the lowest, compared to on the TS. The average Nusselt number ratios ( ) on the TS at Ro = 0.0049 gave higher than on the LS of around 2.17%. On the other hand, the on the TS at Ro = 0.0099 was less than the LS of about 0.08%.
Effect Of 3% Molybdenum (Mo) Nanoparticles on The Melting, Microstructure and Hardness Properties of As- Reflowed Low Mass Sn-58Bi (SB) Solder Alloy
Authors: Singh Amares , Durairaj Rajkumar , Kuan Seng How
Published: November 2020

The Sn-58Bi (SB) lead free solder alloy tested in this research with addition of 3% Molybdenum (Mo) nanoparticles equivalent to 0.6g mass to analyse the influences in the thermal, microstructure and microhardness. Elevation of 3.8°C was observed from the Differential Scanning Calorimetry (DSC) for the 3% Mo nanoparticles added SB solder alloy compared to the bare Sn-58Bi (SB) solder alloy that has a melting temperature of 142.25°C. The microstructures of the reinforced SB solder alloy were refined with closer lamellar structures of ?-Sn and Bi phases compared to the unreinforced SB solder. The SEM/EDX and X-ray Diffraction (XRD) results validate the presence of the 3% Mo nanoparticles in the SB solder. Mechanical properties by means of Vickers microhardness of the Mo reinforced solder alloy showed an increment in hardness value by 2% compared to the bare SB solder alloy. The presence of 3% Mo as discrete particles (dispersion strengthening) contributes to the increase on the hardness value. The introduction of 3% Mo in to the SB solder alloy resulted in increase in the hardness due to the refinement of the microstructure and at the same time allows low temperature soldering in the electronic packaging industry.

Published: November 2020

Objective: Solubility of naproxen sodium is limited. In conventional dosage form it causes different gastro intestinal problems. To overcome these difficulties naproxen sodium loaded nano sponges were designed.

Methodology: Nanosponges were formulated by using emulsion solvent evaporation technique. To obtain dispersion of nanosponges, homogenization of active drug, with specified quantities of polyvinyl alcohol, dichloromethane, ethyl cellulose and distilled, water was done. Compatibility among excipients and active drug was checked by FTIR and results didn’t show any interaction between them. 11 trial formulations were tested for poly dispersity, zeta potential, particle size and viscosity.

Results: Results showed all formulations except NS9, NS10 and NS11 were in nano range. Formulation NS1 to NS6 fall in category of “mid poly dispersity” and formulation NS7 to NS11 were in the category of “very poly dispersity”. Values of Zeta potential of all formulations were in negative range -0.106 to -9.75 mV. The value of viscosity of all formulations were 0.8872. NS2 and NS3 were selected for further testing like Franz cell diffusion study, stability testing and drug loading efficiency. In Franz cell diffusion study, drug release for NS2= 89.62%, for NS3= 89.10% at 50 minutes’ time. Stability studies performed for the 21 days, NS2 and NS3 revealed slight change in percentage drug content at 4°C and 25°C, and major changes were observed at 45°C temperature. Drug loading efficiency was found in NS2= 97.659 % and for NS3= 98.901%.

Conclusion: Nanosponges formulations loaded with naproxen sodium have successfully been prepared.

Nonadiabatic Turbulence Driving during Gravitational Collapse
Authors: Guerrero-Gamboa Rubén , Vázquez-Semadeni Enrique
Published: November 2020

We investigate the generation of turbulence during the prestellar gravitational contraction of a turbulent spherical core. We define the ratio g of the one-dimensional turbulent velocity dispersion

to the gravitational velocity

to then analytically estimate g under the assumptions of (a) equipartition or virial equilibrium between the gravitational (

) and turbulent kinetic (

) energies and (b) stationarity of transfer from gravitational to turbulent energy (implying

cst). In the equipartition and virial cases, we find

and

, respectively; in the stationary case we find

, where η is an efficiency factor,

is the energy injection scale of the turbulence, and R is the core’s radius. Next, we perform AMR simulations of the prestellar collapse of an isothermal, transonic turbulent core at two different resolutions, and a nonturbulent control simulation. We find that the turbulent simulations collapse at the same rate as the nonturbulent one, so that the turbulence generation does not significantly slow down the collapse. We also find that (a) the simulations approach near balance between the rates of energy injection from the collapse and of turbulence dissipation; (b)

, close to the “virial” value (turbulence is 30% ∼ 40% of nonthermal linewidth); (c) the injection scale is

, and (d) the “turbulent pressure”

scales as

, an apparently nearly adiabatic scaling. We propose that this scaling and the nearly virial values of the turbulent velocity dispersion may be reconciled with the nondelayed collapse rate if the turbulence is dissipated as soon as it is generated.
Formation of the Cosmic-Ray Halo: Galactic Spectrum of Primary Cosmic Rays
Authors: Dogiel V. A. , Ivlev A. V. , Chernyshov D. O. , Ko C.-M.
Published: November 2020

A self-consistent model of a one-dimensional cosmic-ray (CR) halo around the Galactic disk is formulated with the restriction of a minimum number of free parameters. It is demonstrated that the turbulent cascade of MHD waves does not necessarily play an essential role in the halo formation. Instead, an increase of the Alfvén velocity with distance to the disk leads to an efficient generic mechanism of the turbulent redshift, enhancing CR scattering by the self-generated MHD waves. As a result, the calculated size of the CR halo at lower energies is determined by the halo sheath, an energy-dependent region around the disk beyond which the CR escape becomes purely advective. At sufficiently high energies, the halo size is set by the characteristic thickness of the ionized gas distribution. The calculated Galactic spectrum of protons shows a remarkable agreement with observations, reproducing the position of the spectral break at

TeV and the spectral shape up to ∼10 TeV.
Aharonov–Bohm oscillations and equilibrium current distributions in open quantum dot and in ring interferometer
Authors: Tkachenko Olga A. , Baksheev Dmitry G. , Tkachenko Vitaly A.
Published: November 2020

Magnetotransport in two submicron-sized devices formed on the basis of GaAs/AlGaAs structures has been simulated using nonequilibrium Green functions. The effect of a perpendicular magnetic field on quantum transport in a quasi-one-dimensional quantum dot and in an Aharonov–Bohm interferometer has been analyzed in a single-particle approximation. Magnetic field oscillations of two-terminal conductance of the devices, equilibrium (persistent) current distributions and magnetic moment generated in the devices by persistent currents have been determined using numerical methods. Correlations between the magnetic moment, magnetic field oscillations of conductance and energy resonance in a specific magnetic field have been traced. Sufficiently regular conductance oscillations similar to Aharonov–Bohm ones have been revealed for a quasi-one-dimensional quantum dot at small magnetic fields (0.05–0.4 T). For a ring interferometer the contribution to the total equilibrium current and magnetic moment at a specific energy may change abruptly both in magnitude and in sign as a result of changing magnetic field within one Aharonov–Bohm oscillation. We show that the conductance of an interferometer is determined not by the number of modes propagating in the ring but rather by the effect of triangular quantum dots at the ring entrance that produce a strong reflection. The period of the calculated Aharonov–Bohm oscillations is in agreement with the measurement results for these devices.
Morphology-based taxonomic re-assessment of the Arctic lamprey, Lethenteron camtschaticum (Tilesius, 1811) and taxonomic position of other members of the genus

The lamprey genusLethenteronCreaser & Hubbs, 1922 is widespread across Eurasia and North America, but the number and distribution of its constituent species is not firmly established. After a morphological examination of extant type material of the currently recognized species and their synonyms,Lethenteron mitsukurii(Hatta, 1901) is resurrected withLe. matsubaraiVladykov & Kott, 1978 as its junior synonym. Amongst nonparasitic speciesLe. reissneri(Dybowski, 1869) andLe. mitsukuriiare confirmed as present in Japan and the former is also present on Sakhalin. An in-depth study of large samples of nonparasitic lamprey adults from Japan and Sakhalin Island is needed to determine whether the lower trunk myomere (< 66) individuals from these areas represent one or more undescribed species, orLe. mitsukurii, orLe. reissneri, or a mixture of these three alternatives.

Authors: Grošelj Robert
Published: November 2020

Prispevek obravnava prevajanje bolgarskih zamenjalnih odvisnikov v slovenščino in primerja opise tovrstnih odvisnikov v slovanskem, predvsem bolgarskem in slovenskem jezikoslovju. Bolgarski zamenjalni odvisniki in njihove prevodne ustreznice so si podobni po pomenu, modalnosti, časovno-dobni perspektivi in osebkovnosti; slovenske ustreznice pa se razlikujejo od izvirnih odvisnikov predvsem po zgradbi, položaju in rabi glagolskih oblik. Opisi zamenjalnih odvisnikov v slavistiki izpostavljajo njihove posebne pomenske (npr. protivnost) in zgradbene značilnosti (npr. vezniška sredstva, glagolske oblike).
Pourquoi les praticiens disent-ils que « la théorie n’est pas utile à la pratique » ? une proposition pour adapter la pratique aux exigences du 21ème siècle
Authors: Fielding Alison J.
Published: November 2020

Les liens entre théorie et pratique dans l’orientation professionnelle posent de nombreux problèmes aux praticiens, en ce qui concerne l’utilité perçue du discours théorique pour ceux qui ont la charge du public. Cet article vise à engager une réflexion critique sur les approches « traditionnelles » de l’orientation professionnelle, et à évoquer quelques-unes des évolutions actuelles qui infléchiront notre approche dans les années à venir : changements dans les profils d’emploi, et dans les conceptions de la vie professionnelle, utilisation des technologies de l’information, développement de l’apprentissage tout au long de la vie, et surtout multiculturalisme.On discutera du besoin actuel de modèles d’orientation qui intégreraient ces changements, et on évoquera les innovations en cours dans ce domaine. On abordera les façons possibles d’utiliser les modèles, et on suggèrera une approche éclectique et intégrée pour répondre à la diversité des besoins du public, en relation avec l’environnement de chaque individu. Ce modèle, fraîchement élaboré sur la base des recherches en cours, pourra figurer comme un outil puissant, et cependant souple, dans le répertoire du praticien de l’orientation professionnelle.
Modeling Antenna Radiation Using Artificial Intelligence Techniques

Published: November 2020

The forward and the inverse problem of a thin, circular, loop antenna that radiates in free space is modeled and solved by using soft computing techniques such as artificial neural networks and adaptive neuro fuzzy inference systems. On the one hand, the loop radius and the observation angle serve as inputs to the forward model, whereas the radiation intensity is the output. On the other hand, the electric field intensity and the loop radius are the input and output, respectively, to the inverse model. Extensive numerical tests indicate that the results predicted by the proposed models are in excellent agreement with theoretical data obtained from the existing analytical solutions of the forward problem. Thus, the employment of artificial intelligence techniques for tackling electromagnetic problems turns out to be promising, especially regarding the inverse problems that lack solution with other methods.

Objetivo: descrever a percepção de enfermeiros que atuam na Atenção Básica sobre as ações de educação em saúde direcionadas aos adolescentes. Método: estudo descritivo exploratório, de abordagem qualitativa. Os dados foram coletados por meio de entrevistas semiestruturadas, áudio-gravadas no mês de novembro de 2017, com 15 enfermeiros atuantes em um distrito sanitário da capital de Mato Grosso do Sul. As entrevistas foram transcritas na íntegra e submetidas à análise temática de Minayo. Resultados: Na maioria das vezes, os enfermeiros realizam ações educativas de caráter informativo que não estimulam o autocuidado dos adolescentes com a sua saúde. Por vezes, o Programa Saúde na Escola é a referência para os profissionais na elaboração de estratégias de educação em saúde, especialmente pelas dificuldades decorrentes da baixa procura dos adolescentes pelos serviços de saúde e pela ausência de estratégias educativas para trabalhar com eles. Conclusão: Há necessidade de maiores investimentos em educação permanente, na implementação de políticas públicas existentes e em programas de intervenção que favoreçam o desenvolvimento de estratégias de incentivo para o autocuidado de adolescentes pelos profissionais da Atenção Básica.

Morphology, structure, magnetic properties and magnetic circular dichroism (MCD) were studied for the FexSy and FexSey nanoparticles (NPs) synthesized with the polyol mediated and the thermal decomposition processes, correspondingly, at different regimes. For all NPs samples, but Fe3S4, MCD was measured for the first time. It has been shown that in the case of sulfides, the character of the MCD spectrum changes as the NPs phase composition transforms from Fe3S4 to FeS with the synthesis temperature increase. At the same time, the shape of the MCD spectrum is almost independent of the NPs phase in the case of iron selenides

Anisotropic periodic relief in form of ripples was formed on surface of amorphous hydrogenated silicon (a-Si:H) films by femtosecond laser pulses with the wavelength of 1.25 μm. The orientation of the surface structures relative to laser radiation polarization vector depended on the number of laser pulses N acting on the film surface. When N = 30, the structures with 0.88 μm period were formed orthogonal to the laser radiation polarization; at N = 750 the surface structures had period of 1.12 μm and direction parallel to the polarization. The conductivity of the laser-modified a-Si:H films increased by 3 to 4 orders of magnitude, up to 3.8·10–5 (Ω∙cm)–1, due to formation of nanocrystalline Si phase with a volume fraction from 17 to 30%. Anisotropy of the dark conductivity, as well as anisotropy of the photoconductivity spectral dependences was observed in the modified films due to depolarizing influence of periodic microscale relief and uneven distribution of nanocrystalline Si phase within such laser-induced structure.

In the present paper we demonstrate and compare different properties of Bi and Bi1-xSbxthin films placed on polyimide (PI) substrate in frequency range from 0.2 to 1.0 THz. Bi films with a thickness of 40, 105 and 150 nm have been studied as well as 150 nm Bi1-xSbxsolid solutions with Sb concentration of 5, 8, 12 and 15 %. An effective refractive index and permittivity of whole substrate/film structures have been derived by using terahertz time-domain spectroscopy (THz-TDS) method. These measurements have shown the positive phase shift in PI substrate with a thickness of 42 μm and revealed that it is barely transparent in studied frequency range, but the whole substrate/film structure provides the negative phase shift of terahertz wave. It was shown that the permittivity depends on mobility of charge carriers which is driven by film thickness and antimony content.

An understanding of the magnetic properties in an amorphous alloy requires comprehensive studies of magnetic anisotropy at various scales. In this paper such a study is carried out using amorphous ribbons FeCuNbSiB. The magnetic anisotropy associated with the rolling axis of ribbons does not affect hysteresis loop measurements, but the disappearance of a fingerprint-like pattern in the domain structure occurs in different fields when they are applied along and transverse the rolling axis. A correlation between the local magnetic anisotropy constant and the nanoscale within which the local easy axis is ordered was found.

The paper presents the results of a study of the protective properties of composite coatings obtained on AMg3 aluminum alloy by plasma electrolytic oxidation (PEO) and subsequent modification of formed oxide layer with superdispersed polytetrafluoroethylene (SPTFE) from a suspension based on isopropyl alcohol. The incorporation of fluoropolymer decreased the porosity of base PEO-coating more than one order of magnitude. Formed composite layers increased wearproof of the samples by more than two orders of magnitude in comparison with PEO-coating. Additionally, polymer-containing coatings has higher adhesion compared to substrate. Formed composite layers possess superhydrophobic properties: contact angle attains 155°.
Relationship between the Photoluminescence Spectra and IR Spectroscopy of Mesoporous Silicon Samples during Long-Term Storage: The Effect of Immersion in an Aqueous LiBr Solutions

Published: November 2020

Studies are devoted to determining the effect of long-term storage (up to 200 days) of untreated and immersion-treated layers of mesoporous silicon in an aqueous lithium bromide solution obtained by anodizing with a current density of 10 mA/cm2 in electrolyte HF: CH3OH = 2: 1. It was found that an increase in the PL intensity and its saturation with a storage time of more than 100 days in all samples is observed. A detailed analysis of absorbance on bonds in m/por-Si showed that during storage, hydrogen bonds are destroyed, and the PL peak intensity is proportional to the increasing concentration of non-stoichiometric oxide, in which oxygen atoms forms radiative states. It was shown that in the treated samples, the PL intensity decreases with increasing immersion time, but the mechanism of photoluminescence through the quantum size confinement (QSC) effect in mesoporous silicon without and with immersion in an aqueous LiBr solution is not significant.

It has been previously found that the blockade of metabotropic glutamate receptor type 5 (mGluR5) protects against hepatic ischemia/reperfusion injury and acetaminophen toxicity. The role of mGluR5 in NAFLD has not yet been elucidated. Here, we evaluated the effects of mGluR5 blockade in an in vitro model of steatosis. HepG2 cells were pre-incubated for 12 h with an mGluR5 agonist, a negative allosteric modulator (DHPG and MPEP, respectively) or vehicle, then treated with 1.5 mM oleate/palmitate (O/P) for another 12 h. Cell viability was evaluated with the MTT assay; fat accumulation was measured using the fluorescent dye nile red; SREBP-1, PPAR-α, iNOS and Caspase-3 protein expression were evaluated by Western blot; NFkB activity was evaluated as pNFkB/NFkB ratio. mGluR5 modulation did not alter cell viability in O/P-incubated cells; MPEP prevented intracellular lipid accumulation in O/P treated cells; MPEP administration was also associated with a reversion of O/P-induced changes in SREBP-1 and PPAR-α expression, involved in free fatty acid (FFA) metabolism and uptake. No changes were observed in iNOS and Caspase-3 expression, or in NFkB activity. In conclusion, mGluR5 pharmacological blockade reduced fat accumulation in HepG2 cells incubated with O/P, probably by modulating the expression of SREBP-1 and PPAR-α.
