Authors: Wang Song , Xie Ming , Zhang Jiming , Chen Yongtai 
Published: December 2013

Abstract
The 0.3%Y2O3/0.3%La2O3/0.3%Al2O3/Cu composite was prepared by oxygen and nitrogen atomization spray deposition technique, internal oxidation, and then treated by annealing at different temperatures. Physical properties such as microstructures, fracture appearance, hardness, strength, electrical conductivity, and arc erosion surface of the composite were investigated. The experimental results show that with an increase in the annealing temperature, the grains of the composite grow up obviously and the electrical conductivity of the composite increases gradually, while the hardness and the tensile strength decrease. When the annealing temperature reaches 1000°C, the matrix grains begin to appear as annealing twins. The tensile fracture morphology of the composite that has been treated by annealing at 700°C for 2 h shows a huge number of large and deep dimples, in which the metallic oxide particles exist. The fracture mode of the composite is the microporous polycondensation plastic fracture. The arc erosion surface shows a large number of paste-like coagulum and bubbles.

Authors: Srinivasa Chikkol Venkateshappa , Suresh Yalaburgi Jayadevappa , Kumar Wooday Puttiah Prema 
Published: December 2013

Abstract
The present paper presents the finite element studies made on critical buckling load of isotropic and laminated composite cylindrical skew panels. Analysis is performed using CQUAD4 and CQUAD8 elements of MSC/NASTRAN. It is found that the CQUAD8 element yields better results compared to the CQUAD4 element in terms of accuracy and convergence. Using the CQUAD8 element, the effects of the panel angle, skew angle, aspect ratio, and length-to-thickness ratio on the critical buckling load of isotropic cylindrical skew panels have been studied. The effects of additional parameters such as fiber orientation angle, numbers of layers (NL), and stacking sequence on the critical buckling load of laminated composite cylindrical skew panels have also been studied. The critical buckling loads are found to increase with the increase in panel angle and skew angle. When the NL in the laminate is large, the variation of the critical buckling load with the NL is not appreciable. The boundary conditions are found to have significant influence on the critical buckling load.
Ravel and Robert-Houdin, Magicians
Authors: Fillerup Jessie 
Published: December 2013

Abstract
When Claude Debussy called Ravel an “enchanting fakir” in 1907, he anticipated a critical approach typified by Vladimir Jankélévitch's 1939 Ravel biography. In it, Jankélévitch evoked the rich language of theatrical magic, comparing Ravel to a sorcerer, conjurer, and illusionist. Contemporary critics used similar terms to describe the composer's music as early as 1909, around the same time that a parallel narrative emerged: Ravel as a master of mechanism and artifice. A contextual study of theatrical magic, which has yet to be applied to Ravel criticism, provides a substantive connection between these narratives of mechanism, enchantment, and artifice.
I begin with the French illusionist Robert-Houdin (1805–71), whose enduring legacy furnishes a forgotten background for Ravel criticism. Robert-Houdin claimed that he was not a mere juggler but “an actor playing the part of a magician,” which resonates with accounts of Ravel's Baudelairean artifice in life and work. For magicians, “illusion” was interchangeable with “effect.” The word “effect” recurs in both Ravel's writings and “The Philosophy of Composition,” a theoretical-didactic essay by Edgar Allan Poe, whom Ravel cited as one of his most important artistic influences. Ravel's appreciation of Poe has a much richer grain than has been imagined, extending beyond compositional artisanship to include literary and theatrical stratagems.
Robert-Houdin, who started his career as a clockmaker, featured automata at his Soiréé fantastiques—but sometimes, like von Kempelen's Turk, these automata were illusions themselves. Ravel's fascinations with enchantment and mechanism converge in the presence of these trick machines. In the opera L'Enfant et les sortilèges (1925), Ravel uses techniques known to both magicians and cognitive neuroscientists, exploiting the aural equivalent of an afterimage and manipulating the spectator's attentional frames.

The Algorithm for Determining the Coordinates of a Point in Three-Dimensional Space by Using the Auxiliary Point
Authors: Oszczak Bartlomiej , Sitnik Eliza 
Published: December 2013

ABSTRACT
During the process of satellite navigation, and also in the many tasks of classical positioning, we need to calculate the corrections to the initial (or approximate) location of the point using precise measurement of distances to the permanent points of reference (reference points). In this paper the authors have provided a way of developing Hausbrandt's equations, on the basis of which the exact coordinates of the point in two-dimensional space can be determined by using the computed correction to the coordinates of the auxiliary point. The authors developed generalised equations for threedimensional space introducing additional fixed point and have presented proof of derived formulas.
Development of an Integrated Digital Elevation Model for Safe Takeoff and Landing of the Aircraft
Authors: Ciećko Adam , Jarmołowski Wojciech 
Published: December 2013

ABSTRACT
The article describes preliminary results of the augmentation of Global Navigation Satellite System/Inertial Navigation System positioning (GNSS/INS) by Digital Elevation Model (DEM) based on the data from the Shuttle Radar Topography Mission (SRTM) and data from field survey.
The prototype software is developed to refer the position of the aircraft to DEM and informs the user about the current relevant flight parameters. The number of the parameters may be arbitrarily increased, however, currently we investigate the altitude above the terrain and the aircraft position relative to the descent path and airfield.
The study provides some information on the local SRTM accuracy in relation to the field survey of the airfield "Dajtki" - Aeroclub of Warmia and Mazury in Olsztyn.
Agent-Based Evolutionary Method of Simulation the Co2 Emission Permits Market
Authors: Stańczak Jarosław 
Published: December 2013

Abstract
This article describes the problem of simulation of the CO2 emission permits market. First, it introduces a CO2 permission market model with transactions and purchase prices, in particular with a separate goal function for each party, transactions with price negotiations between regions and - as a consequence of introducing prices for permits - the possibility of investigating the influence of purchase/sale prices on the market. The behavior of such market model is simulated using a method, which is based on a specialized evolutionary method but introduces independent agents with their own transaction preferences.

Published: December 2013

Abstract
In this paper we focused on the history of floods and extreme flood frequency analysis of the upper Danube River at Bratislava. Firstly, we briefly describe the flood marks found on the Danube River in the region of Bratislava, Slovakia, and provide an account of the floods’ consequences. Secondly, we analyzed the annual maximum discharge series for the period 1876-2012, including the most recent flood of June 2013. Thirdly, we compare the values of T-year design discharge computed with and without incorporating the historic floods (floods of the years 1501, 1682, and 1787 into the 138-year series of annual discharge peaks). There are unfortunately only a few historic flood marks preserved in Bratislava, but there are very important and old marks in neighbouring Hainburg and other Austrian cities upstream to Passau. The calculated T-year maximum discharge of the Danube at Bratislava for the period 1876-2010 without and with historic flood values have been compared. Our analysis showed that without incorporating the historic floods from the years 1501, 1682, and 1787 the 1000-year discharge calculated only with data from the instrumented period 1876- 2013 is 14,188 m3 s-1, and it is lower compared to the 1000-year discharge of 14,803 m3 s-1 when the three historic floods are included. In general, the T-year discharge is higher throughout the whole spectrum of T-year discharges (10, 20, 50, 100, 200, 500-year discharge) when the three historic floods are included. Incorporating historic floods into a time series of maximum annual discharge seems to exert a significant effect on the estimates of low probability floods. This has important implications for flood managements and estimation of flood design discharge.
Talking Suicide
Authors: Westerlund Michael 
Published: December 2013

Abstract
The present article discusses intimate conversations about suicide that are pursued on the Internet. Computer-mediated communication has made it possible for participants to remain anonymous and, simultaneously, enter into a public space to share personal thoughts about a stigmatized and taboo subject. This has also created new and unique opportunities to study a type of communication that was previously very difficult to access. Most of the participants on the studied forum are teenagers or young adults who communicate based on a need to recognize themselves in others, and to receive acknowledgement for their thoughts, feelings and experiences, thereby gaining acceptance and understanding. However, there are also destructive elements in the form of an exchange of suicide methods and participants exhorting each other to go ahead with their suicide plans. Moreover, participants are able to practise suicide behaviour in a mediated, conversational form, thereby making the act seem less fearful. The participants are furthermore involved in constructing and re-constructing a counter-discourse in which established society’s perceptions and values concerning suicide are questioned, as expressed in a critique against public institutions, mainly psychiatry.
The Mashups of YouTube
Authors: Simonsen Thomas Mosebo 
Published: December 2013

Abstract
This article focuses on YouTube mashups and how we can understand them as a specific subgenre on YouTube. The Mashups are analysed as audiovisual recontextualizations that are given new meaning, e.g., via collaborative social communities or for individual promotional purposes. This is elaborated on throughout a discussion on Mashups as a mode of everyday bricolages, which are moreover discussed through a theoretical approach to Mashups as exponents of what has been called “Vernacular Creativity”. The article also argues that the novelty of Mashups is not be found in its formal characteristic, but rather in its social and communicative abilities within the YouTube community. This leads to the article’s overall argument that the main characteristic of the YouTube Mashup can be explained in terms of connectivity. It is argued that Mashups reveal a double articulation of connectivity; one that involves the social mechanisms of the Mashups, and another mode, which concerns the explicit embedding of structural connectivity that accentuates the medium-specific infrastructure of YouTube. This double articulation of connectivity is furthermore elaborated on by including Grusin and Bolter’s concept of remediation.
Methodologically, the article draws on empirical observations and examples of Mashups are included to demonstrate the article’s main arguments.
Use of Development Dialogues in Learning and Changing Journalism Practice
Authors: Hujanen Jaana 
Published: December 2013

Abstract
The present article analyses a case study in which the author experimented with use of the interventionist development dialogue method in journalism practice. Journalistic work is conceptualized as a network of multivoiced, contradictory, historically changing and artefact-mediated activity systems. Through the use of development dialogues, the study aimed at understanding and facilitating the innovation, change and expansive learning that can take place in relation to journalistic work. The data include collaboration between the researcher and four Finnish newspaper journalists, pre- and post-intervention interviews, and diaries kept by the journalists. The data were analysed using the methods of qualitative text analysis. The case study indicates that an interventionist research approach that focuses on journalists’ personal experiences and needs, and makes use of concrete development tasks, is of value to them. It fosters the imagination and the creation of novel journalistic and discursive practices that help journalists reflect on, understand and pursue journalism. As power relations and control impinged on and were manifest in the research process, the development task-oriented interventionist research approach calls for a thorough evaluation that looks at the power relations within an activity system and at the question of the political aim of an interventionist research approach.
Fluctuations of tidewater glaciers in Hornsund Fjord (Southern Svalbard) since the beginning of the 20th century
Authors: Błaszczyk Małgorzata , Jania Jacek A. , Kolondra Leszek 
Published: December 2013

Abstract
Significant retreat of glaciers terminating in Hornsund Fjord (Southern Spits− bergen, Svalbard) has been observed during the 20th century and in the first decade of the 21st century. The objective of this paper is to present, as complete as possible, a record of front positions changes of 14 tidewater glaciers during this period and to distinguish the main factors influencing their fluctuations. Results are based on a GIS analysis of archival maps, field measurements, and aerial and satellite images. Accuracy was based on an as− sessment of seasonal fluctuations of a glacier’s ice cliff position with respect to its mini− mum length in winter (November-December) and its maximum advance position in June or July.Morphometric features and the environmental setting of each glacier are also pre− sented. The total area of the glacier cover in Hornsund Fjord in the period of 1899-2010 diminished approximately 172 km2, with an average areal retreat rate of 1.6 km2a−1. The recession rate increased from ~1 km2a−1 in first decades of the 20th century up to ~3 km2a−1 in years 2001-2010. The latest period was more thoroughly studied using optical satellite images acquired almost every year. The importance of glacier morphology and hypspmetry, as well as fjord bathymetry and topography is analyzed. Large glacier systemswith low slopes terminating in deeper waters are retreating faster than small steep glaciers ter− minating in shallower water. A relation between mean annual air temperature and aerial retreat rate of tidewater glaciers was found for long time scales. A sudden temperature in− crease, known as the early 20th century warming in Svalbard, and an increase in temperatures during recent decades are well reflected in deglaciation rate. Influence of sea water temperatures on calving and retreat of glaciers was considered and is significant in short−time intervals of the last decade. Surge events are non−climatic factors which com− plicate the record. They are reflected in front advance or fast retreat due to a massive calving depending on the relation between ice thickness and water depth. Despite the influence of many factors, the response of tidewater glaciers to climate change is evident. The average linear retreat rate of all the tidewater glaciers in Hornsund amounted to ~70 ma−1 in 2001-2010 and was higher than the average retreat of other Svalbard tidewater glaciers (~45 ma−1). Thus, glaciers of this basin can be considered as more sensitive to climate than glaciers of other regions of the archipelago.
Effects of Energy and Macronutrient Intake on Cognitive Function Through the Lifespan
Authors: Gibson Edward Leigh 
Published: December 2013

Abstract
This paper reviews effects of both insufficient and excessive energy and macronutrient intake on cognition over the lifespan, including the prenatal period, infancy, childhood, and adulthood. In the brain, the hippocampus is particularly vulnerable to both protein malnutrition and energy undernutrition in utero or infancy, resulting in impaired neurogenesis and deficits in memory and spatial learning, reduced anxiety and increased impulsivity, reflected in impairments of neurotransmitter systems. Conversely, higher protein intake is associated with improved motor development but not mental development, whereas breastfeeding benefits mental development. Nevertheless, pre- and post-natal protein-energy supplementation has been shown to improve cognition in later childhood, and in adulthood, above energy alone. Similarly, n-3 essential fatty acid intake during pregnancy may have long-lasting effects on children’s cognitive abilities. However, over-nutrition, particularly during gestation, may lead to metabolic programming that increases risk of cognitive impairment. In undernourished school children, breakfasts can benefit cognitive performance. In normally nourished children, benefits of breakfast are less clear; nevertheless, acutely, breakfasts lower in glycaemic index can benefit memory, whereas higher glycaemic breakfasts may improve vigilance. This difference depends on the impact of the carbohydrate on cortisol release. In adolescents and adults, moderate carbohydrate loads can benefit cognition, provided that glucoregulation is efficient. Protein intake may benefit memory by restraining task-related cortisol release. Chronically high intake of saturated fats may contribute to cognitive decline, whereas n-3 fatty acids, and perhaps reduced energy intake, may be protective. With aging populations, dietary prediction of cognition in adults is a key area for research.
Content of Alkylresorcinols in Cereals Grown in Latvia Determined by High Performance Liquid Chromatography with UV

Published: December 2013

Abstract
Cereal alkylresorcinols (ARs) are a group of phenolic lipids mainly found in the outer parts of grains of rye and wheat. They have been suggested for use as selective biomarkers for intake of whole grain and bran products of these cereals. Consumption of whole grains and whole grain products has been associated with reduced risk of developing chronic diseases, such as cardiovascular disease, diabetes type 2, obesity and some types of cancer. In this article a sensitive and rapid method of High Performance Liquid Chromatography with UV detection for quantitative determination of ARs in the cereals grown in Latvia is described. Instrument detection limits (IDL) were determined for C17:0, C19:0 and C21:0 homologues (coefficient of variation < 3%). According to the results of these studies, ARs were found in rye (87.1-112.0 mg/100 g), wheat (24.0-40.2 mg/100 g), triticale (32.1-74.4 mg/100 g), and in small amounts in barley (2.2-3.7 mg/100 g), but not in oats.

Published: December 2013

Abstract
Various extracts of Japanese quince (Chaenomeles japonica) seeds obtained using organic solvents were studied for their polyphenol content and antiradical activity. It was established that petroleum ether, hexane, ethyl acetate, acetone, as well as toluene and chloroform extracts, in comparison to synthetic antioxidant butylated hydroxytoluene (BHT), demonstrate better (or comparable) activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH). Methods for detoxification of seeds, meals and press-cakes are proposed. Phenolic composition of different extracts (80% ethanol, 70% acetone), both acid and alkali hydrolysates of seeds, as well as seed oil methanol/water extract were analysed by means of high performance liquid chromatography (HPLC): chlorogenic acid was found for the first time in seed extract; protocatechuic acid predominated in all extracts. The content of other major phenolic acids was detected; it was found that seed oil contains syringic acid. It was determined that Japanese quince seeds contain almost ten times more α -tocopherol than barley grain. Due to the presence of α -tocopherol and phenolic compounds, seed oil and lipophilic extracts of seeds could serve as antioxidants.

Abstract
Marshmallow is sugar-candy with foam-like structure. Many studies have revealed the high nutritional value of bee pollen. Due to the nutritional composition of pollen, and according to nonscientific studies, dried bee pollen has been used as an additive in human diets, which provides a well-being sensation and contributes to functional and harmonious balance of the body. Sensory evaluation and market research are an important part of developing a new product. The research was aimed to clarify the situation in the Latvian market, to summarise Latvian consumer attitude on marshmallow, and to determine the sensory properties and quality of marshmallows with bee pollen. A questionnaire was developed - 900 respondents answered questions about their consumption patterns, opinions on quality indices, and possible types of marshmallow packaging. Marshmallow was enriched with three different pollen concentrations: 1.0; 1.5 and 2.5%. Sensory evaluation was carried out to estimate the optimal concentration of bee pollen that which should be added to marshmallow. Sensory evaluation of experimental marshmallow was characterised by using a 9-point hedonic scale (determination degree of liking). The obtained results showed that consumers liked the marshmallow with 1.5% bee pollen best of all.
