Objective: To analyse the opening diameter of incisive foramen as a parameter for gender and age estimation by using cone beam computed tomography (CBCT). Material and Methods: After approval by the local research ethics committee, CBCT images were obtained from the dental database of a diagnostic centre and then selected. Images suggesting presence of periapical lesions and periodontal changes were excluded, as well as those of patients undergoing orthodontic treatment, with trauma to the mid-facial third, with cleft/lip palate, cranial or syndromic morphological changes, or even absence of one of the upper incisors. The images of male and female patients were distributed according to age groups (i.e. 10-30 years, 31-50 years, and 51 years or older) and then assessed twice and independently by three surgeon-dentists with experience in radiology by means of the XoranCat® software. The resulting data were tabulated and statistically analysed by using the SAS® software (version 2003) – PROC GLM for mixed generalised models – and Tukey’s test for comparison of the mean values at 5% significance level. Results: Considering the methodology used, the results have demonstrated no statistically significant difference in the method for gender estimation. However, it was observed that there was a gradual increase in the mean values as the age advances in the majority of the age groups for both males and females, with a statistically significant difference (P<0.05) regarding age estimation. Conclusion: The use of incisive foramen as a gender parameter has had a limited forensic value, but it is an innovative approach in the process of age estimation.KeywordsDentistry; Human identification; Anatomy; Computed tomography.
Avaliação da distribuição de Gumbel na determinação de vazões mínimas da sub-bacia do Rio Negro
Authors: Pereira Gislaine Silva , Caldeira Fernanda Vilasboas
Published: December 2017

A água é o recurso natural que possibilita a vida na terra, e a falta de informações a respeito da gestão deste recurso dificulta o planejamento e a tomada de decisão adequados. Deste modo, em busca de determinação do risco de ocorrências de vazões mínimas, que podem vir a restringir o abastecimento de água, através de estudos de qualidade de água estimam-se a ocorrência de vazões utilizando curvas de probabilidades. Com isso, o objetivo do trabalho foi verificar a adequabilidade do modelo de probabilidade de Gumbel ao ajuste da série histórica de 33 anos de vazões mínimas provenientes da sub-bacia do Rio Negro. O Rio Negro abrange 22 municípios entre Santa Catarina e São Paulo possuindo várias estações fluviométricas em suas proximidades, na qual os dados escolhidos para este estudo foram da estação de fragosos (Águas do Paraná) no município de Piên, PR. A aplicação do modelo de Gumbel demonstrou que até o tempo de retorno de 20 anos há variabilidade nos dados, após isso a distribuição não se adequa a série histórica. Pode se concluir que a utilização do modelo de Gumbel não se adequou a todos os meses da série histórica em questão, comprovado com a realização de testes de aderência estatística.
Eje 2. El cine argentino y español: épocas, aportes y debates: El Desencanto y la muerte de la familia
Authors: Bergua Amores José Angel
Published: December 2017

El filme español El Desencanto (Jaime Chávarri, 1976), si bien ha solido ser interpretado como una crítica al Régimen político de Franco e incluso al tipo de clase social y familia que lo sostuvieron, también admite una lectura de más largo alcance. El artículo sugiere que el filme es expresión de la crisis de tres arquetipos que sostienen o merodean la institución familiar: el patriarcal, el matriarcal y el que está llamado a sustituir a ambos, el fratriarcalismo.
Eje 2. El cine argentino y español: épocas, aportes y debates: Las tres versiones del mito de King Kong o la Modernidad como crisis
Authors: Roche Cárcel Juan A.
Published: December 2017

En este artículo se parte de la hipótesis de que el cine de terror —y King Kong de manera singular— prospera en las etapas agudas de crisis social. Concretamente, KingKong, con sus tres versiones más importantes —1933, 1975 y 2015—, representa una muestra paradigmática, en tanto que, estimulado por las importantes crisis económica de 1929, de 1973 y de 2011, crea imaginariamente un raro ser natural de tamaño descomunal, monstruoso, que encarna simbólicamente los miedos de la época, a la Historia, a la acción humana, al progreso y su correspondiente anhelo de un futuro mejor. Para desarrollar esta hipótesis de partida, este trabajo se apoya, fundamentalmente, en dos perspectivas de la Sociología —la comprensiva de Max Weber y la Sociología del Cine— que entroncan con dos métodos —el hermenéutico y el análisis iconológico—, así como con los conceptos de imaginario social y de crisis.
Eje 3. Producciones cinematográficas contemporáneas: características y estrategias narrativas: Los géneros cinematográficos, entre la historia de la sociedad y la historia de un lenguaje
Authors: Triquell Ximena
Published: December 2017

El título de este trabajo remite a la frase de Mijail Bajtin: «Los enunciados y sus tipos, es decir, los géneros discursivos, son correas de transmisión entre la historia de la sociedad y la historia de la lengua» (Bajtin, 1952–1953:251). Resulta evidente que Bajtin en esta frase se está refiriendo a géneros en un sentido muy diferente que el que éste término adquiere en relación a la producción cinematográfica. No obstante, creemos que en ella puede encontrarse una hipótesis interesante para abordar la compleja relación entre el cine y la sociedad en que éste es producido y consumido. En efecto, recordemos que la preocupación fundamental de Bajtin está dada por el estudio del «enunciado», esto es la lengua, no como sistema abstracto sino en sus usos concretos. En este marco, la noción de género sirve a este autor para superar la distinción tajante entre sistema (lengua) y uso individual (habla). Entre ambas, los géneros, en tanto  «tipos relativamente fijos de enunciados», regulan nuestros intercambios lingüísticos, desde los más simples, como el saludo (a los que llama géneros primarios) hasta los más complejos como una novela (a los que llama secundarios o ideológicos). De allí que Bajtin considere que «el género es una entidad más sociohistórica que formal» y que por lo tanto «las transformaciones del género deben ser puestas en relación con los cambios sociales». Para Todorov, la posición privilegiada del concepto de género dentro del pensamiento bajtiniano se sostiene precisamente en esta función mediadora entre «la historia de la sociedad y la historia de la lengua» (Todorov, 1991:165–ss). En este trabajo nos interesa recuperar esta noción para pensar los géneros cinematográficos como mediadores entre las formas cinematográficas y la historia de la sociedad en las que éstas son producidas.
“El paro o Argelia”: la expatriación de los españoles en Argelia como salida laboral
Authors: Cabezón Fernández María Jesús , Sempere Souvannavong Juan David
Published: December 2017

La movilidad transnacional de personas cualificadas entre España y Argelia conoce un importante cambio a raíz de la intensificación de las relaciones comerciales bilaterales, dando lugar a una movilidad Norte-Sur. La instalación de empresas extranjeras en Argelia favoreció la movilidad de personas con alta cualificación motivadas por la posibilidad de desarrollar sus carreras con unas buenas condiciones laborales. La crisis económica y social ha provocado la intensificación de la movilidad transnacional española hacia Argelia, a la que se han unido pequeños empresarios y personas sin empleo que se lanzan a la búsqueda de un trabajo incluso de forma irregular. En este trabajo nos centraremos en analizar, con una aproximación cualitativa, cómo la crisis ha afectado a la movilidad transnacional de los expatriados españoles, que han pasado del privilegio a la precarización, en un contexto percibido como adverso, pero necesario para evitar el desempleo en España.
Trayectorias y expectativas en China. Una aproximación descentrada a la movilidad internacional española
Authors: Sáiz López Amelia
Published: December 2017

La década de 2010 ha despertado el interés investigador sobre flujos emergentes de jóvenes cualificados hacia Europa y América Latina. La migración internacional española no se agota en esos destinos. Una aproximación descentrada permite abordar a los residentes españoles en Shanghai elaborando una tipología desde la perspectiva de las movilidades donde confluyen procesos analizados separadamente en los estudios de migración previos. La complejidad de la movilidad no se explica únicamente por las dimensiones geográfica o laboral. A partir de entrevistas en profundidad, el análisis cualitativo propuesto muestra la necesidad de entrecruzar todas las dimensiones que intervienen en la toma de decisiones individuales y colectivas y las diferentes estrategias, en un sistema de género dado, y de acuerdo a objetivos, posiciones sociales y familiares, recursos y capitales, en el marco de la  globalización.
La emigración española cualificada tras la crisis. Una comparación con la migración desde el Sur de Europa e Irlanda
Authors: González-Enríquez Carmen , Martínez Romera Jose Pablo
Published: December 2017

El artículo presenta un análisis de la emigración española cualificada reciente en comparación con la procedente de Italia, Grecia, Portugal e Irlanda. La fuente utilizada es una encuesta europea que entrevistó a 6.750 personas procedentes de estos cinco países. Se ha indagado en los motivos de la emigración, en la situación laboral y de ingresos en el país de origen y de destino, en la frecuencia del registro consular y las dificultades experimentadas en la integración. Los españoles han resistido en su país más tiempo que los demás nacionales antes de tomar la decisión de emigrar, su salida ha estado más motivada por el desempleo y se encuentran en una peor situación en el país de destino, están en paro con mayor frecuencia y reciben ingresos inferiores, una diferencia que se acentúa en el caso de las mujeres. Su dominio del idioma del país de destino es menor y ello causa a los españoles mayores dificultades de todo tipo, laborales y vitales.
Radiation Biomarkers : Applications in Triage Management of Radiation Victims
Authors: Mishra Saurabh , Kumar Raj
Published: December 2017

Human exposure to ionizing radiation disrupts normal metabolic processes in cells and organs by inducing complex biological responses that interfere with gene and protein expression. Conventional dosimetry, monitoring of prodromal symptoms and peripheral lymphocyte counts are of limited value as organ- and tissue-specific biomarkers for personnel exposed to radiation, particularly, weeks or months after exposure. Analysis of metabolites generated in known stress-responsive pathways by molecular profiling helps to predict the physiological status of an individual in response to environmental or genetic perturbations. There is a need for research to rapidly determine an individual’s absorbed dose and its potential health effects after a potential radiological or nuclear event that could expose large portions of a population to ionizing radiation. Studies on biomarker identification after radiation exposure could contribute in biodosimetry, identifying individual dose absorbed, as well as biologic response, and administering immediate and proper medical care. In the recent scenario development of biomarker is major thrust area. In the present review paper articles related to gene biomarker, protein biomarker and metabolic biomarker are reviewed in order to sketch an overview on the recent advances related to developing an biomarker to assess the radiation induced toxicity.
Microfluidic Integrated Technology: A Potential Tool for Portable Radiation Biodosimetry
Authors: Khan Shahrukh , Kumar Shravan , Banchariya Shivani , Kumar Raj
Published: December 2017

In the event of a mass radiological or nuclear incident, a large number of individuals would require rapid biodosimetric screening for proper medical care, mitigation and follow-up procedures. Mass radiological triage is critical after any such large-scale event because of the need for Dose assessment of suffered individuals at an early stage. With the increasing probability of such unprecedented incidents around the world, the need for modelling and development of new medical countermeasures for potential future chemical, biological, radiological and nuclear has been well established. Unfortunately, the capacity of most of these methods are still restricted to laboratory establishments due to resource limitations, need of high end expertise or general immobility of bulky instruments required for the same. So far there exists no rapid diagnostic technique that may reliably discriminate levels of ionising radiation exposure based on samples collected at a single time point. In classical clinical settings, complete blood count, particularly the lymphocyte count is based on temporal assessment. The diagnostic ‘gold standard’ in the field of radiation biodosimetry is the dicentric chromosome assay which happens to be highly labour-intensive and extensively time consuming, rendering it inefficient in case of mass casualty situations. Advanced technologies such as microfluidic platform, BioMEMS, μTAS carry the potential to make system highly portable, cost efficient and independent of high skilled expertise. In this review of the latest advances in portable biodosimetry we evaluate our progress and identify areas that still need to be addressed to achieve true field-deployment readiness.

Authors: Kumar M.S. Yogendra , Raghu T. S. , Varghese F. V. , Kotresh T. M.
Published: December 2017

Flavonoid-rich fraction (FRF) from Seabuckthorn leaves extract was prepared by acid hydrolysis process. Total flavonoid content of Seabuckthorn leaves extract and FRF estimated as rutin equivalent was found to be 116.98±3.06 and 277.14 ± 6.78 mg/g of extract/FRF respectively. Its major constituents myrcetin, quercetin, kaempferol and isorhamnetin, were determined by reverse phase high performance liquid chromatography (RP-HPLC). Aramid (NomexIIIA) fabric was treated with triethylene tetramine to increase the wicking height of the fabric for better uptake of FRF. Then, FRF was coated using citric acid as cross linking agent on to aramid fabric by pad-dry-cure method for improved wash durability. FRF coated fabric was characterised using Universal attenuated total internal reflection Fourier Transform Infrared spectroscopy. Effect of FRF coating on flammability property of coated fabric was estimated using flammability tester. There was no significant difference in the char length of the FRF coated fabric and control samples. 

Antimicrobial activity of the FRF coated fabric was assessed by both qualitative (agar diffusion method; AATCC 147-2001) and quantitative (percentage reduction test; (AATCC 100-2001) methods using test organisms. The zone of inhibition by agar diffusion method for E. coli and S. aureus was found to be 12.4 mm and 16.7 mm respectively. Quantitative assessment by percentage reduction test showed a reduction percentage of 96.00% and 93.00% for S. aureus and E. coli, respectively. The results of the above study indicate FRF as a valuable ingredient for the development of antimicrobial textiles.

Published: December 2017

Magnetic iron oxide nanoparticles (MNPs) with appropriate surface chemistry exhibit many interesting properties that can be exploited in a variety of biomedical applications such as magnetic resonance imaging contrast enhancement, tissue repair, hyperthermia, drug delivery and in cell separation. In this study unexplored Lagenaria siceraria leaves extract was found to be capable in green synthesis of Iron oxide nanoparticles (Fe3O4-NPs) and their characteristics were studied by using UV-visible spectrophotometer, SEM, EDX, XRD, Zeta sizer and FT-IR. Thus synthesized Fe3O4-NPs were naturally stabilized, cubic shaped and in the size range of 30-100 nm. The phytochemicals present in the leaf has a main role as reducing agent that assists to the eco friendly synthesis of Fe3O4-NPs with enhanced antioxidant property. Functional groups present on the NPs are mainly –OH and –COOH (FT-IR) makes it hydrophilic hence NPs does not need any further functional modification for applications. The antimicrobial property of synthesized Fe3O4-NPs was evaluated against Gram negative - Escherchia coli, Gram positive- Staphylococcus aureus, The Zone of inhibition was found to be 10 mm for Escherchia coli, and 8 mm for Staphylococcus aureus. Thus naturally stabilized Fe3O4-NPs with herbal property can be used in various biological applications.

Authors: Kartik S.N. , K. Mohanavelu , Reddy M.V. Mallikarjuna , Anandan M.
Published: December 2017

EEG signal is one of the most complex signals having the lowest amplitude which makes it challenging for analysis in real-time. The different waveforms like alpha, beta, theta and delta were studied and selected features were related with the consciousness levels. The consciousness levels detection is useful for estimating the subjects’ performance in certain selected tasks which requires high alertness. This estimation was performed by analyzing signal properties of the EEG using features extracted through discrete wavelet transform with a moving window of 10 seconds with 90% overlap. The EEG signal is decomposed in to wavelets and the average energy and power of the coefficients related to the EEG bands is taken as the features. The data is collected from standard EEG machine from the volunteers as per the protocol. C3 and C4 locations (unipolar) of the standard 10-20 electrode system were selected. The central region of the brain is most optimal location for the consciousness levels detection. The estimation of the data using Discrete Wavelet Transform (DWT) energy, power features provided better accuracy when the central regions were chosen. An accuracy of 99% was achieved when the algorithm was implemented using a classifier based on linear kernel support vector machines (SVM).
A FPGA based Steganographic System Implementing a Modern Steganalysis Resistant LSB Algorithm
Authors: Pathak Kunjan , Bansal Manu
Published: December 2017

Steganography differs from other data hiding techniques because it encodes secret message inside cover object in such a way that transmission of secret message also remains a secret. Widespread usage of digital images, lower computational complexity and better performance makes spatial domain steganographic algorithms well suited for hardware implementation, which are not very frequent. This work tries to implement a modern steganalysis resistant LSB algorithm on FPGA based hardware. The presented work also optimises various operations and elements from original one third probability algorithm with respect to hardware implementation. The target FPGA for the implementation is Xilinx SP605 board (Spartan 6 series XC6SLX45T FPGA). Stego images obtained by the implementation have been thoroughly examined for various qualitative and quantitative aspects, which are found to be at par with original algorithm.
Fractional Calculus Guidance Algorithm in a Hypersonic Pursuit-Evasion Game
Authors: Chen Jian , Zhao Qilun , Liang Zixuan , Li Peng , Ren Zhang , Zheng Yongjun
Published: December 2017

Aiming at intercepting a hypersonic weapon in a hypersonic pursuit-evasion game, this paper presents a fractional calculus guidance algorithm based on a nonlinear proportional and differential guidance law. First, under the premise of without increasing the complexity degree of the guidance system against a hypersonic manoeuvering target, the principle that the differential signal of the line-of-sight rate is more sensitive to the target manoeuver than the line-of-sight rate is employed as the guidelines to design the guidance law. A nonlinear proportional and differential guidance law (NPDG) is designed by using the differential derivative of the line-of-sight rate from a nonlinear tracking differentiator. By using the differential definition of fractional calculus, on the basis of the NPDG, a fractional calculus guidance law (FCG) is proposed. According to relative motions between the interceptor and target, the guidance system stability condition with the FCG is given and quantitative values are also proposed for the parameters of the FCG. Under different target manoeuver conditions and noisy conditions, the interception accuracy and robustness of these two guidance laws are analysed. Numerical experimental results demonstrate that the proposed guidance algorithms effectively reduce the miss distance against target manoeuvers. Compared with the NPDG, a stronger robustness of the FCG is shown under noisy condition.
Investigation of Incompressible Flow Past Two Circular Cylinders of Different Diameters
Authors: Bhumkar Yogesh , Kumar Priyank , Roy Arnab , Das Sudip , Prasad Jai Kumar
Published: December 2017

A two - dimensional Navier-Stokes solver based on finite volume approach using a boundary-fitted curvilinear structured O-grid has been developed to obtain details of unconfined flow past cylinders at low Reynolds number of 100 and 200 based on diameter. Computations made on a single cylinder with smaller domain adopting the convective boundary conditions captured most of the flow features. This concept of a smaller domain, when used to capture the highly complex flow field around two cylinders of the same diameter placed in tandem at a Reynolds number of 200 showed reasonable results. The details of the flow field around two cylinders of different diameters placed at a typical distance of 3L and Reynolds number of 100 could be well captured adopting smaller domain concept. It is observed that the change in diameter of upstream cylinder strongly influences the overall flow field and the drag of the downstream cylinder.

Authors: M R Subash Chandrabose , Victor Pereira Shan , B Jayakumar , D. Ebenezer D.
Published: December 2017

Segmented ring transducers are widely used for low frequency, broadband, deep submergence applications. These transducers can be made out of piezoceramic wedges or slabs and metallic wedges. Higher diameter, low frequency transducers are generally made out of piezoceramic slabs and metal wedges due to ease of manufacture and low cost. In this paper, metal ceramic segmented ring transducers are modelled using ATILA, a finite element software for the design of underwater transducers. Transducer variants were modelled with different wedge and piezoceramic materials. Transducers modelled were manufactured, assembled and tested. Various stages of manufacture like piezoceramic stacking, transducer assembly, pre-stressing with fibre winding, and encapsulation are explained. Acoustic performances of the transducers manufactured were measured in an open tank and inside a pressurised vessel from 10 bar to 70 bar. Performance parameters like resonance frequency, transmitting voltage response and directivity were measured. Results indicate that the transducer has usable bandwidth of about two octaves and stable response. One of the transducers was also tested in a high pressure test facility at 600 bar to check its pressure withstanding capability.

Published: December 2017

In the present work, fabrication and evaluation of low density glass – epoxy (LDGE) composites suitable for absorbing minimum 80 per cent of incident microwave energy in 8 GHz to 12 GHz (X-band) is reported. LDGE composites having different densities were fabricated using a novel method of partially replacing conventional S-glass fabric with low density glass (LDG) layers as the reinforcement materials. Flexural strength, inter laminar shear strength and impact strength of the prepared LDGE composites were evaluated and compared with conventional High density glass-epoxy (HDGE) composites to understand the changes in these properties due to replacement of S-glass fabrics with LDG layers. To convert LDGE structures to radar absorbing structures controlled quantities of milled carbon fibers were impregnated as these conducting milled carbon fibers can act as dielectric lossy materials which could absorb the incident microwave energy by interfacial polarisation. Electromagnetic properties namely loss tangent and reflection loss of carbon fiber impregnated LDGE composites were evaluated in 8 GHz -12 GHz frequency region and compared with HDGE composites. It was observed that both LDGE and HDGE composites have shown loss tangent values more than 1.1 and minimum 80 per cent absorption of incident microwave energy. Thus the results indicates that, LDGE composites can show EM properties on par with HDGE composites. Furthermore these LDGE composite could successfully withstand the low velocity impacts (4.5 m/s) with 50 J incident energy. Due to their ability to show good mechanical properties and light weight, LDGE composites can be used as a replacement for conventional HDGE composites to realise radar absorbing structures.

Authors: Gutierrez Gonzalez Mateo , Bonilla Santos Jessika Isabel , Cruz Amado Maria Fernanda , Quintero Aranzalez Juan Guillermo
Published: December 2017

La Guadua angustifolia Kunth es una especie de bambú que ha sido ampliamente utilizado en la construcción. Gracias a su capacidad de absorber agua, la G. angustifolia experimenta cambios en sus dimensiones, resistencia y rigidez debido a la variación del contenido de humedad. El punto de saturación de las fibras (PSF) se alcanza cuando a un determinado contenido de humedad el material no presenta cambios dimensionales ni variaciones en la resistencia mecánica. Para determinar el PSF de G. angustifolia se analizaron probetas de la parte inferior, intermedia y superior de la guadua. Se utilizaron dos metodologías: el primer método midió la variación dimensional, encontrando que el PSF está alrededor de 34.05 %; el segundo determinó la variación de la resistencia a la compresión paralela, encontrando que el PSF está alrededor de 34 %. Por último, se presentaron los factores de modificación de la resistencia a compresión para diferentes contenidos de humedad, así como la ecuación de expansión lineal del material.

Mathematical modelling of thermal and flow processes in vertical ground heat exchangers
Authors: Pater Sebastian , Ciesielczyk Włodzimierz
Published: December 2017

The main task of mathematical modelling of thermal and flow processes in vertical ground heat exchanger (BHE-Borehole Heat Exchanger) is to determine the unit of borehole depth heat flux obtainable or transferred during the operation of the installation. This assignment is indirectly associated with finding the circulating fluid temperature flowing out from the U-tube at a given inlet temperature of fluid in respect to other operational parameters of the installation.

The paper presents a model of thermal and flow processes in BHE consisting of two analytical models separately-handling processes occurring inside and outside of borehole. A quasi-three-dimensional model formulated by Zeng was used for modelling processes taking place inside the borehole and allowing to determine the temperature of the fluid in the U-tube along the axis of BHE. For modelling processes occurring outside the borehole a model that uses the theory of linear heat source was selected. The coupling parameters for the models are the temperature of the sealing material on the outer wall of the borehole and the average heat flow rate in BHE. Experimental verification of the proposed model was shown in relation to BHE cooperating with a heat pump in real conditions.
Kierkegaard’s Reception in Lithuania
Authors: Bachmetjevas Viktoras
Published: December 2017

This article discusses the reception of Søren Kierkegaard in Lithuania. Kierkegaard was introduced into Lithuania in the 1970’s through an extract from Either/Or and immediately received attention from the young upcoming scholar Arvydas Šliogeris. However, due to the politically charged preference for Marxism-Leninism, it is not surprising that the interest in Kierkegaard could gather pace only after Lithuania regained independence in 1990. Since then five books by Kierkegaard have been translated and published.

Published: December 2017

LTE technology has been designed to serve high data traffic and to withstand occasional traffic bursts caused by various events that arise when live video streams are watched. LTE will have to manage its resources judiciously since video traffic is not constant, and at the same time it will have to seek to offer highest quality experience. This paper demonstrates the benefits of using MIMO technique with 4 transmitters instead 2 when requesting live video streams. It also displays mobility cases each with a different subscriber moving speed, and with different gains, respectively.

Published: December 2017

A d0-algebra, which is a generalization of a D-lattice, is an algebraic structure with one operation, called difference, and a distinguished element denoted by 0.

In this paper we investigate those uniformities on a d0-algebra which make the difference uniformly continuous. We prove that such uniformities are univocally determined the neighbourhoods of 0, thus extending the corresponding result known for D-lattices.

Selective degeneration of dopamine neurons in Parkinson’s disease: emerging roles of altered calcium homeostasis and nucleolar function
Authors: Parlato Rosanna , Liss Birgit
Published: December 2017

Parkinson’s disease (PD) is the second most common neurodegenerative disease. Its classic major motor-symptoms are caused by the progressive loss of dopamine in the striatum, and of dopamine (DA) releasing neurons in the midbrain, particularly within the Substantia nigra (SN). The cause for PD is still unclear, hampering the development of curative therapies. However multiple genetic and environmental PD trigger factors have been identified, pointing to a common, mutually interdependent pathomechanism of cell-specific metabolic dysfunction and altered gene expression. Here, we summarize and discuss these emerging PD-pathomechanisms, that could provide novel potential therapeutic targets, with a focus on altered Ca2+ homeostasis and nucleolar function. We discuss how animal models with impaired nucleolar ribosomal RNA synthesis can enable identification of novel cell-specific vulnerability factors, and how complex homeostatic adaptation of SN DA neurons could enable a flexible adjustment of their functional activity to metabolic needs, but also might render them particularly vulnerable to degenerative triggers and cell-death in PD.

Published: December 2017

The aim of this study is to present the results of commissioning of Elekta Synergy linear accelerator (linac). The acceptance test and commissioning were performed for three photon beams energies 4 MV, 6 MV and 15 MV and for the multileaf collimator (MLC). The percent depth doses (PDDs), in-plane and cross-plane beam profiles, head scatter factors (Sc), relative photon output factors (Scp), universal wedge transmission factor and MLC transmission factors were measured. The size of gantry, collimator, and couch isocenter were also measured.
Plasticity Modelling in PM Steels
Authors: Andersson M. , Angelopoulos V.
Published: December 2017

Simulations are continuously becoming more and more important to predict the behaviour of materials, components and structures. Porous materials, such as PM, put special demands on the material models used. This paper investigates the application of the Gurson material model to PM steels. It is shown how the model can be calibrated to material data. The results are also applied to an indentation test, where it’s demonstrated that experimental results can be reproduced with some accuracy. Limitations of the model, and the potential to use more advanced material models are also discussed.
Hybrid suburbia: New research perspectives in France and Southern California
Authors: Weber Florian , Kühne Olaf
Published: December 2017

Geographical research on French and US suburbia has concentrated in recent decades on urban sprawl and concomitant processes of devaluation and exclusion. In the case of the Frenchbanlieues, with their much-publicised urban riots, this particular analytic focus has become overwhelming, with resultant loss to other developments and perspectives. However, certain districts in the first (or inner) ring of both French and US suburbia are currently showing distinct urbanisation tendencies in planning and architecture, evident in the new usage of brownfield sites and the ongoing demolition, replacement, and rededication of the older building core. Such processes induce population changes, e.g. the displacement of lower in favour of higher income groups. Overall, they result in an architectonic, social and cultural heterogeneity that escapes the specificity of received categories and merits the term hybridisation. The article describes and compares these processes as exemplified in Greater Paris and San Diego (Southern California).
Home range size and breeding dispersal of a common buzzard (Buteo buteo)
Authors: Väli Ülo
Published: December 2017

Telemetric studies have provided ample information on threatened raptors, but still little is known about space use and dispersal of common species. Here I describe the home range and breeding dispersal of a GPS-tracked adult male common buzzard, studied in south-eastern Estonia in 2014–16. This buzzard’s home range covered 8.3 km2 (kernel 95% estimate) with the core range being 2.1 km2 (kernel 50%). The home range increased in the course of the breeding season but decreased again before migration. Surprisingly, the nests in the two successive breeding years were located in the opposite margins of the home range, 1.7 km from each other.
Johnny Kan
Authors: Chan April
Published: December 2017

Johnny Kan was the first pioneer to promote authentic, Cantonese haute cuisine, both in San Francisco's Chinatown and throughout America-at-large. Kan's lifelong campaign to extricate chop suey from Chinese cuisine and initiate American palates to refined, high-end Cantonese gastronomy is well-documented in San Francisco's annals, particularly through the coruscating pen of San Francisco's beloved raconteur, Herb Caen. Through the décor and the dining rituals of his establishments, Kan also crafted a visual, experiential, and taste aesthetic that was a significant departure from the plate-slamming, indifferent post-World War II chop suey joints of his day. Kan was rightfully Chinatown's first and inimitable culinary ambassador, through the many ways in which he exalted true Cantonese gastronomy with flair, set the restaurant standard to beat from the 1940s until his death in the 1972, and worked with civic influencers to reshape Chinatown's appeal and historical significance.
German Restaurants in San Francisco in the Wake of World War I
Authors: Schmieding Leonard
Published: December 2017

This article challenges the widely accepted view that cultural expressions of Germanness disappeared during World War I in the United States by examining the response of German restaurants to anti-German sentiments. German restaurants in San Francisco responded to the rise of anti-German sentiments in three distinct ways: First, some German restaurateurs veiled German cuisine as American cuisine, adding San Francisco specialties to the menu, and Americanizing the interior of the restaurant; Second, proprietors increasingly relied on non-Germans to decide the quality of the restaurant; Third, German restaurateurs founded new restaurants that openly continued the traditions of turn-of-the-century San Francisco German restaurants.
La situación militar de Galicia tras la guerra de Portugal (1669-1677)
Authors: Saavedra Vázquez María del Carmen
Published: December 2017

La realidad militar de Galicia en los años inmediatos al conflicto portugués es un tema mal conocido y apenas abordado por la investigación. El objetivo de este trabajo es cubrir parte de ese vacío historiográfico, centrando la atención en dos cuestiones fundamentales: la situación de los presidios gallegos y el coste de las operaciones de envío de soldados gallegos a Flandes. Para cubrir tales propósitos, la investigación se apoya en la contabilidad del pagador del ejército de Galicia, Antonio del Río, entre 1669 y 1677. Pese a sus limitaciones, se trata de un documento revelador, que introduce importantes precisiones en nuestros conocimientos y permite comprobar los esfuerzos realizados por la Corona para mantener operativo el sistema militar gallego.
Rapid Bioprosthetic Mitral Valve Failure after Temporary Left Ventricular Assist Device Support
Authors: Schubmehl Heidi B , Saric Muhamed , Vainrib Alan F , Williams Mathew , Balsam Leora B
Published: December 2017

The technique of mechanical circulatory support or the site of cannulation may affect transvalvular flow. We describe early failure of a mitral bioprosthesis in a patient with temporary left ventricular assist device support, likely from thrombosis. Salvage with transcatheter mitral valve replacement was attempted. Temporary mechanical circulatory support strategies that maximize flow across a new bioprosthesis should be sought to avoid early valvular thrombosis.
Variación ontogénica y sexual de Oecomys bicolor (Rodentia, Cricetidae) de Perú y Ecuador
Authors: Menajovsky Bonifaz Maria Fernanda , Pacheco Torres Victor Raul
Published: December 2017

Oecomys es un género moderadamente especioso de tamaño pequeño a mediano y coloración característica. Dentro del género, la especie O. bicolor es reconocida morfológicamente con relativa facilidad; sin embargo, se ha reportado variaciones individuales, en tamaño y color, de distintas poblaciones que sugieren la especie podría ser un complejo de especies. La información intraespecífica presente en O. bicolor es muy poca a pesar de su amplia distribución; no obstante, esta información es necesaria para la delimitación de la especie así como explicar variaciones en poblaciones.  Por ello, en el presente estudio se analizaron 148 especímenes de O. bicolor, con el objetivo de evaluar lavariación no geográfica referida al sexo y edad.  Las muestras se organizaron formando grupos según su distribución geográfica y se analizaron 13 variables cráneo-dentales. Mediante aproximaciones estadísticas univariadas y multivariadas se demostró que el dimorfismo sexual no es significativo, por otro lado la variación ontogénica es considerable entre jóvenes y adultos. Se recomienda continuar los estudios de variación geográfica tomando en cuenta las edades 3, 4 y 5, y juntando machos y hembras.

Fueron analizados 9917 ejemplares y registradas un total de 211 especies agrupadas en 28 familias y nueve órdenes.
Emoji Dei
Authors: McIvor Méadhbh , Amesbury Richard
Published: December 2017

A recent proposal to create a hijab emoji raises interesting questions about the place of "religion" among the colorful pictographs that increasingly punctuate our texts, emails, and social media posts. In this exploratory article, we offer some preliminary – and, of necessity, inchoate – reflections on religious representation in the digital age and outline possible avenues of research for colleagues and students to pursue. Of crucial importance, we argue, are what religiously-themed emoji might suggest about the default world in which they operate; a default, we submit, that functions to affirm the normative ascendance of the secular.
