Published: April 2016

Abstract
Reforming cultural policy in Serbia comes into a focus after year 2000. With delegating jurisdiction on the local cultural systems, because one of the ideas is that local government and experts can recognize needs, potential and capacities for local development more clearly and comprehensively. This work deals with the challenges of cultural policy as initiators of sustainable development, where the City of Pancevo has been selected as an example of a good practice. The first part of the text deals with challenges of cultural policy on national level. When it comes to cultural policy development on the Republic level, one can say that participants in culture in Serbia contribute to improving culture every year. However, for more successful cultural policy it is necessary to approach cultural policy challenges in service of sustainable development. Ranking all challenges leads to a conclusion that it is necessary to solve problems such as financing of the institutions, lack of a strategic thinking and insufficient inter-sector, inter -department and international cooperation. The second part of the text is dedicated to the City of Pancevo, as an example of a good practice in cultural policy and sustainable development domain. During 2013. with the support of the IPA fund cross-border cooperation program, the City of Pancevo accomplished Poles of Culture project. Within that project the Center for Study in Cultural Development conducted a research of cultural needs and habits of citizens of Pancevo, cultural institutions and citizen associations within culture. The third part of the text deals with the research results of cultural needs and habits of Pancevo citizens. They represent guidelines for improving the city cultural policy. The fourth part of the text is dedicated to the cultural policy on the local level and recommendations for cultural policy improvement has been given based on the example of the City of Pancevo.

Abstract

Background: The objective of this study was to determine whether there is an association between successful uvulopalatopharyngoplasty (UPPP) and serum uric acid in patients with obstructive sleep apnea (OSA), and identify the risk markers for successful UPPP in OSA patients.

Methods: We performed a prospective cohort study of 73 adult patients with OSA who underwent surgery (nasal or UPPP) at a major, urban, academic hospital in Huaian from 2011 to 2014 who had preoperative and postoperative clinical and laboratory profiles. Demographic, clinical, laboratory, and PSG parameters were carefully recorded. Logistic regression was used for the multivariate analysis of independent risk factors.

Results: Changes of uric acid (UA), changes of C-reactive protein (CRP), changes of triglyceride, changes of high density lipoprotein before and after UPPP were significantly higher in OSA patients with successful UPPP than in those with unsuccessful UPPP (p<0.05). Among these patients, multiple logistic analyses indicated the independent risk factors for successful UPPP in the OSA subjects included changes of UA and CRP before and after UPPP. The diagnosis analysis showed that changes of UA and CRP before and after UPPP had a significant ability to reflect UPPP success in the OSA patients.

Conclusions: The novel finding of this study is that the successful UPPP in OSA patients is strongly related to changes of serum UA level, CRP before and after operation. These results might be helpful for providing valuable information to reflect the effect of UPPP operation, regardless of UA and CRP before operation.

Abstract
Rapid NO2 gas sensor has been developed based on PbS nanoparticulate thin films synthesized by Successive Ionic Layer Adsorption and Reaction (SILAR) method at different precursor concentrations. The structural and morphological properties were investigated by means of X-ray diffraction and field emission scanning electron microscope. NO2 gas sensing properties of PbS thin films deposited at different concentrations were tested. PbS film with 0.25 M precursor concentration showed the highest sensitivity. In order to optimize the operating temperature, the sensitivity of the sensor to 50 ppm NO2 gas was measured at different operating temperatures, from 50 to 200 °C. The gas sensitivity increased with an increase in operating temperature and achieved the maximum value at 150 °C, followed by a decrease in sensitivity with further increase of the operating temperature. The sensitivity was about 35 % for 50 ppm NO2 at 150 °C with rapid response time of 6 s. T90 and T10 recovery time was 97 s at this gas concentration.

Authors: Mostafavi E. , Ataie A. 
Published: April 2016

Abstract
Nanostructured barium doped bismuth ferrite, Bi₀.₈Ba₀.₂FeO₃ porous ceramics with a relatively high magnetic coercivity was fabricated via sacrificial pore former method. X-ray diffraction results showed that 20 wt.% Ba doping induces a structural phase transition from rhombohedral to distorted pseudo-cubic structure in the final porous samples. Moreover, utilizing Bi₀.₈Ba₀.₂FeO₃ as the starting powder reduces the destructive interactions between the matrix phase and pore former, leading to an increase in stability of bismuth ferrite phase in the final porous ceramics. Urea-derived Bi₀.₈Ba₀.₂FeO₃ porous ceramic exhibits density of 4.74 g/cm³ and porosity of 45 % owing the uniform distribution of interconnected pores with a mean pore size of 7.5 μm. Well defined nanostructured cell walls with a mean grain size of 90 nm were observed in the above sample, which is in a good accordance with the grain size obtained from BET measurements. Saturation magnetization decreased from 2.31 in the Bi₀.₈Ba₀.₂FeO₃ compact sample to 1.85 A m²/kg in urea-derived Bi₀.₈Ba₀.₂FeO₃ porous sample; moreover, coercivity increased from 284 to 380 kA/m.

Abstract
Ca2Nd4Ti6O20, a layered perov skite structured material was synthesized via a chemical (citrate sol-gel) route for the first time using nitrates and alkoxide precursors. Phase analysis of a sample sintered at 1625 °C revealed the formation of an orthorhombic (Pbn21) symmetry. The microstructure of the sample after sintering comprised rod-shaped grains of a size of 1.5 to 6.5µm. The room temperature dielectric constant of the sintered sample was 38 at 100 kHz. The remnant polarization (Pr) and the coercive field (Ec) were about 400 μC/cm2 and 8.4 kV/cm, respectively. Impedance spectroscopy revealed that the capacitance (13.7 pF) and activation energy (1.39 eV) of the grain boundary was greater than the capacitance (5.7 pF) and activation energy (1.13 eV) of the grain.

Abstract
In the present paper structural and electronic properties of rare earth pnictides have been presented. The present calculation has been performed using self-consistent tight binding linear muffin tin orbital (TB-LMTO) method within the local density approximation (LDA). The studied compounds undergo a structural phase transition from NaCl-type structure to CsCl-type structure. The electronic band structure and density of states of the pnictides have been reported. The equilibrium lattice parameter a (Å), bulk modulus B (GPa), number of f-states at the Fermi level Nf (states/Ry cell) and volume collapse of AmBi and CmBi have also been reported. The calculated equilibrium structural parameters are in good agreement with the available experimental results.

Published: April 2016

Abstract Surface plasmons provide a pathway to efficiently absorb and confine light in metallic nanostructures, thereby bridging photonics to the nano scale. The decay of surface plasmons generates energetic ‘hot’ carriers, which can drive chemical reactions or be injected into semiconductors for nano-scale photochemical or photovoltaic energy conversion. Novel plasmonic hot carrier devices and architectures continue to be demonstrated, but the complexity of the underlying processes make a complete microscopic understanding of all the mechanisms and design considerations for such devices extremely challenging.Here,we review the theoretical and computational efforts to understand and model plasmonic hot carrier devices.We split the problem into three steps: hot carrier generation, transport and collection, and review theoretical approaches with the appropriate level of detail for each step along with their predictions.We identify the key advances necessary to complete the microscopic mechanistic picture and facilitate the design of the next generation of devices and materials for plasmonic energy conversion.

Abstract
Recent developments in quantum photonics have initiated the process of bringing photonic-quantumbased systems out-of-the-lab and into real-world applications. As an example, devices to enable the exchange of a cryptographic key secured by the laws of quantum mechanics are already commercially available. In order to further boost this process, the next step is to transfer the results achieved by means of bulky and expensive setups into miniaturized and affordable devices. Integrated quantum photonics is exactly addressing this issue. In this paper, we briefly review the most recent advancements in the generation of quantum states of light on-chip. In particular, we focus on optical microcavities, as they can offer a solution to the problem of low efficiency that is characteristic of the materials typically used in integrated platforms. In addition, we show that specifically designed microcavities can also offer further advantages, such as compatibility with telecom standards (for exploiting existing fibre networks) and quantum memories (necessary to extend the communication distance), as well as giving a longitudinal multimode character for larger information transfer and processing. This last property (i.e., the increased dimensionality of the photon quantum state) is achieved through the ability to generate multiple photon pairs on a frequency comb, corresponding to the microcavity resonances. Further achievements include the possibility of fully exploiting the polarization degree of freedom, even for integrated devices. These results pave the way for the generation of integrated quantum frequency combs that, in turn, may find important applications toward the realization of a compact quantum-computing platform.

Published: April 2016

AbstractParkinson’s disease (PD) is the second most common chronic neurodegenerative disease that affects motor skills and cognitive performance. The conventional therapeutic approaches for the management of PD are just able to alleviate symptoms. Exploring for achieving novel substances with therapeutic benefits in PD patients is the focus of a wide range of current investigations. The aim of the present study is to comprehensively review phytochemicals with protective or therapeutic activities in PD and focus on their neuropsychopharmacological mechanisms. Various subgroups of polyphenols (flavonoids, phenolic acids, stilbenes, and lignanes) and terpenes are the most abundant groups of phytochemicals with well-established antiparkinsonian effects. Other phytochemical categories, such as alkaloids, cinnamates, carbohydrates, amino acids, and fatty acid amides, also have some representatives with positive effects in PD. Phytochemicals perform their antiparkinsonian effect through several mechanisms of action, including suppressing apoptosis (via the reduction of Bax/Bcl-2, caspase-3, -8, and -9, and α-synuclein accumulation), decreasing dopaminergic neuronal loss and dopamine depletion, reducing the expression of proinflammatory cytokines (such as prostaglandin E2, interleukin-6, interleukin-1β, and nuclear factor-κB), and modulating nuclear and cellular inflammatory signaling, elevation of neurotrophic factors, and improvement of antioxidant status. Plant-derived natural products can be considered as future pharmaceutical drugs or adjuvant treatment with conventional therapeutic approaches to improve their efficacy and alleviate their psychological adverse effects in the management of PD. Well-designed clinical trials are mandatory to evaluate the protective and healing benefits of phytochemicals as promising future drugs in the management of neurodegenerative diseases.

Solvatación preferencial de la naringina en mezclas cosolventes etanol + agua mediante el método de las integrales inversas de Kirkwood-Buff
Authors: Caviedes Rubio Diego Iván , Sotomayor Pino Reinaldo Gabriel , Delgado Daniel Ricardo 
Published: April 2016

<p>Los parámetros de solvatación preferencial, es decir, las diferencias entre la fracción molar local y de la solución de los solventes en solución de naringina se derivan de su solubilidad en mezclas cosolventes mediante el método de las integrales inversas de Kirkwood-Buff. Según el método IKBI, la naringina es sensible a los efectos específicos de solvatación según la composición cosolvente, por lo que el parámetro de solvatación preferencial por δx1,3, es negativo en mezclas ricas en agua y en mezclas ricas en etanol, pero positivo en composiciones entre 0,24 y 0,40 en fracción molar de etanol. Esto podría demostrar el papel relevante de hidratación hidrofóbica alrededor de los grupos no polares en la solvatación de fármacos en mezclas ricas en agua. Por otro lado, en mezclas de composiciones cosolventes intermedias, el fármaco es solvatado principalmente por etanol, posiblemente debido al comportamiento básico de la mezcla cosolvente; mientras que en mezclas ricas en etanol, la<br />solvatación preferencial por el agua podría deberse al carácter ácido del agua.</p>

<p>La propiedad electroactiva de hidroquinona (HQ) se estudió sobre un electrodo de carbono vítreo modificado con quitosano, nanotubos de carbono de pared múltiple<br />(Ch-MWCNT-GCE). La HQ se depositó a un potencial controlado sobre la superficie del electrodo y la oxidación de la HQ se midió por voltametría de onda cuadrada (SWV, por sus siglas en inglés). Se observó una corriente de oxidación a<br />0,39 V y una corriente de reducción a 0,21 V con un ΔV de 0,18 V; ello indicó un proceso reversible. Un aumento en las corrientes de oxidación y de reducción de casi 50% se observó cuando el Ch-MWCNT-GCE se recubrió con líquido iónico (LI). El electrodo se caracterizó por voltamperometría cíclica (CV, por sus siglas en inglés) en presencia y sin la presencia de diferentes líquidos iónicos con distinto anión,<br />siendo el más óptimo el líquido iónico (LI) 1-butil-3-metilimidazolio hexafluorofosfato (BMIMPF6). Se estudiaron las variables experimentales como pH, tiempo de adsorción (tads) y potencial de adsorción (Eads), así como también las potenciales interferencias. Bajo las óptimas condiciones (pH 3,0; tacc 60s; Eacc 0,10 V), el pico de la corriente es proporcional a la concentración de HQ entre 4,20 × 10-6 y 30,0 × 10-6 mol L-1, con un límite de detección de 2,45 × 10-7 mol L-1. La desviación estándar relativa para una solución que contiene 1,0 × 10-4 mol L-1 de HQ, fue de 1,5% para siete medidas iguales. El método se validó con una muestra de agua dopada con HQ.</p>
