Delayed diagnosis of an isolated partial anomalous pulmonary venous connection
Authors: Glaveckaite Sigita , Lusaite Karolina , Grabauskiene Virginija , Valeviciene Nomeda , Laucevicius Aleksandras
Published: July 2014

In this case report we describe the delayed diagnosis of a very rare congenital anomaly — isolated partial anomalous pulmonary venous connection. This congenital anomaly should be suspected at any age in the clinical setting of right heart volume overload, especially in the absence of a large atrial septal defect. Tomographic imaging modalities (computed tomography or cardiovascular magnetic resonance) not only allow the comprehensive structural and functional assessment of this anomaly, but also help assess the patient’s suitability for surgical treatment. Surgery is the definitive treatment of a patient with a significant left-to-right shunt due to partial anomalous pulmonary venous connection.
Gitelman syndrome DD thiazide diuretics abuse
Authors: Keller Karsten , Beule Johannes , Dippold Wolfgang
Published: July 2014

Introduction. Gitelman syndrome (GS) is a rare inherited disorder. Mutations in SLC12A3 gene that encode tubular Na+Cl-cotransporter (NCCT) cause hypokalemic metabolic alkalosis, salt loss, hypomagnesaemia and hypocalciuria. The symptoms include weakness, vertigo, hypotension, tetany, paresthesia and nausea. Diagnostic criteria are a normal urine concentrating ability, normal glomerular filtration rate (GFR), hypomagnesaemia (<0,65mmol/l), hypokalemia (<3,6mmol/l) and hypocalciuria (<0,1mmol/mmol creatinine). Previously, the diagnosis was made by exclusion. Today, genetic analysis can ensure diagnosis. Thiazide diuretics (TD) abuse with similar abnormalities can make the differential diagnosis difficult. Causal therapy of GS does not exist. The substitution of potassium and magnesium are therapeutic strategies. Case presentation. A 41-year-old obese woman presented at the emergency department with recurrent episodes of hypokalemia with concomitant weakness, muscle cramps, polyuria and collapse. The results of laboratory testing of blood and urine led to the suspected diagnosis of GS. In the follow-up examinations, the results were inconsistent. Therefore, a transient thiazide diuretics abuse was assumed. Discussion. This case demonstrates the difficulties in making the diagnosis of GS on the basis of only clinical and laboratory tests, without the use of genetic analysis. The differentiation between GS and thiazide diuretic abuse is especially difficult.
Effect of peat samples drying on measured content of carbon and nitrogen fractions
Authors: Jonczak Jerzy
Published: July 2014

The aim of the study was to compare the content of carbon and nitrogen fractions in fresh and dried samples of peat. The samples were extracted in 0.25 mol KCl·dm.-3, 0.25 mol H2SO4·dm.-3 and 2.5 mol H2SO4·dm.-3. Based on the extractions and analysis of total organic carbon (TOC) and total nitrogen (TN) following fractions of carbon and nitrogen were isolated: nonhydrolyzable carbon (NHC) and nitrogen (NHN), hardly hydrolyzable carbon (HHC) and nitrogen (HHN), easy hydrolyzable carbon (EHC) and nitrogen (EHN), dissolved organic nitrogen (DON), and its ammonium (NH4.-N) and nitrate (NO3.-N) form. Large differences between fresh and dried samples were observed in the content of some analyzed fractions . especially NO3.-N, NH4.-N, DON and HHC. 1.6.3.5 times higher concentrations of NO3.-N were observed in dry samples in comparison with fresh. In dried samples were also observed higher concentrations of NH4.-N and DON. In general lower concentrations of EHN, NHN, HHC and higher of HHN and EHC were observed in dried samples in comparison to fresh. Higher content of mineral nitrogen, as well as DON and DOC in dried samples, is probably an effect of mineralization of carbon and nitrogen compounds during initial stage of drying. The obtained data suggest, that the content of NO3.-N, NH4.-N, DON and EHC analyzed in dried samples of peat is overestimated. Extractions of the fractions from organic samples should be done based on fresh samples, just after sampling
„Quaternary rendzinas” in the Systematics of Polish Soil
Authors: Lemkowska Bożena
Published: July 2014

It is suggested that calcareous soils formed from calcareous gyttja were termed quaternary rendzinas, as indicated by Uggla. Their differentiation is connected with the amount of calcium carbonate and anthropogenic modification of surface horizon. Soils being in the initial phase of organic matter accumulation are suggested to be termed initial quaternary rendzinas, whereas the soils that have humus horizon more than 10 cm thick - proper quaternary rendzinas. Taking into consideration the fact that humus horizon of these soils is developed during siltation with alluvial or deluvial deposits, separation of calcareous post-lacustrine soils in alluvial and deluvial soils should be considered alternatively.

The state of ionic balance in selected plant species from natural habitats of the Piska Primeval Forest (NE Poland)
Authors: Brogowski Zygmunt , Czępińska-Kamińska Danuta
Published: July 2014

The objective of this paper was an attempt to estimate the impact of variable habitat conditions on the ionic state and ionic balance of selected species of plants occurring in an environment with scarce anthropogenic pressure in the Piska Primeval Forest, north-eastern Poland. The analysed mono- and dicotyledonous plants showed very high amounts of total nitrogen, exceeding sum of alkaline cations (Ca2+, Mg2+, K+, Na+), particularly at poor natural habitats (Sphagno-girgensohni-Picetum and Pino-Quercetum communities). Lack of alkaline cations is probably compensated by nitrogen in the form of NH4+, therefore maintaining the ionic balance of cations and anions in plants. Plants inhabiting habitats such as the Tilio-Carpinetum community show very high amounts of potassium. Some potassium radioactivity is probably indispensable for the physiological processes in plants instead of solar radiation
Conservation status and sustainable local use of crop and crop wild relative species in the Bistoon protected area / West of Iran
Authors: Rostami Reza , Khoshbakht Korous
Published: July 2014

Collecting information about crop wild relatives (CWRs) as vital genetic resources for food security is the first stage of monitoring them. In this study, which was conducted in a protected area, we surveyed the conservation status of CWR sand, and the interaction between the condition of these plants and their local use. From 338 plant species in the area, 179 crop wild relatives in 38 families were identified. None of them is threatened, but some endemic rare or vulnerable plants such as Alkanna frigida Boiss. could cause some anxiety. Among these species 19 species of CWRs have edible usage in this area. Harvesting the crop wild relatives from nature by the local people is seen as a conservative factor although this is not usually true of other species.
Modernity and Gender: A Critique of Modernization Theory
Authors: Luintel Youba Raj
Published: July 2014

This paper provides a bold critique of the hegemonic dualism in the light of insights that Tariq Banuri has offered. It also demonstrates the contours of gender asymmetry as an outcome of the masculine impersonal map of modernization. Highlighting the alternative model of development, it seeks to see the implication it has in the context of gender. The first section introduces the context with some of the questions to be focused on. It follows by a discourse of modernization and by an appraisal of Banuri’s main arguments on cultural maps and knowledge hierarchy. Conceptual contours of modernization and gender are sought before the final section puts forward empowerment as an alternative thesis.

Maximum Entropy in Drug Discovery
Authors: Tseng Chih-Yuan , Tuszynski Jack
Published: July 2014

Drug discovery applies multidisciplinary approaches either experimentally, computationally or both ways to identify lead compounds to treat various diseases. While conventional approaches have yielded many US Food and Drug Administration (FDA)-approved drugs, researchers continue investigating and designing better approaches to increase the success rate in the discovery process. In this article, we provide an overview of the current strategies and point out where and how the method of maximum entropy has been introduced in this area. The maximum entropy principle has its root in thermodynamics, yet since Jaynes’ pioneering work in the 1950s, the maximum entropy principle has not only been used as a physics law, but also as a reasoning tool that allows us to process information in hand with the least bias. Its applicability in various disciplines has been abundantly demonstrated. We give several examples of applications of maximum entropy in different stages of drug discovery. Finally, we discuss a promising new direction in drug discovery that is likely to hinge on the ways of utilizing maximum entropy.
Analysis of Operation Parameters in a Dual Fluidized Bed Biomass Gasifier Integrated with a Biomass Rotary Dryer: Development and Application of a System Model
Authors: Puadian Nargess , Li Jingge , Pang Shusheng
Published: July 2014

An integrated system model was developed in UniSim Design for a dual fluidized bed (DFB) biomass gasifier and a rotary biomass dryer using a combination of user-defined and built-in unit operations. A quasi-equilibrium model was used for modelling biomass steam gasification in the DFB gasifier. The biomass drying was simulated with consideration of mass and energy balances, heat transfer, and dryer’s configuration. After validation using experimental data, the developed system model was applied to investigate: (1) the effects of gasification temperature and steam to biomass (S/B) ratio on the gasification performance; (2) the effect of air supplied to the fast fluidized bed (FFB) reactor and feed biomass moisture content on the integrated system performance, energy and exergy efficiencies. It was found that gasification temperature and S/B ratio have positive effects on the gasification yields; a H2/CO ratio of 1.9 can be achieved at the gasification temperature of 850 °C with a S/B ratio of 1.2. Consumption of excessive fuel in the system at higher biomass feed moisture content can be compensated by the heat recovery such as steam generation while it has adverse impact on exergy efficiency of the system.

Published: July 2014

MicroRNAs (miRNAs) have essential roles in carcinogenesis and tumor progression. Here, we investigated the roles and mechanisms of miR-143 in non-small cell lung cancer (NSCLC). miR-143 was significantly decreased in NSCLC tissues and cell lines. Overexpression of miR-143 suppressed NSCLC cell proliferation, induced apoptosis, and inhibited migration and invasion in vitro. Integrated analysis identified LIM domain kinase 1 (Limk1) as a direct and functional target of miR-143. Overexpression of Limk1 attenuated the tumor suppressive effects of miR-143 in NSCLC cells. Moreover, miR-143 was inversely correlated with Limk1 expression in NSCLC tissues. Together, our results highlight the significance of miR-143 and Limk1 in the development and progression of NSCLC.

Published: July 2014

Enterovirus 71 is one of the major causative agents of hand, foot and mouth disease in children under six years of age. No vaccine or antiviral therapy is currently available. In this work, we found that the number of B cells was reduced in enterovirus 71-infected mice. Deferoxamine, a marine microbial natural product, compensated for the decreased levels of B cells caused by enterovirus 71 infection. The neutralizing antibody titer was also improved after deferoxamine treatment. Furthermore, deferoxamine relieved symptoms and reduced mortality and muscle damage caused by enterovirus 71 infection. This work suggested that deferoxamine has the potential for further development as a B cell-immunomodulator against enterovirus 71.
On the Physics of Machining Titanium Alloys: Interactions between Cutting Parameters, Microstructure and Tool Wear
Authors: Nouari Mohammed , Makich Hamid
Published: July 2014

The current work deals with the analysis of mechanisms involved during the machining process of titanium alloys. Two different materials were chosen for the study: Ti-6Al-4V and Ti-55531. The objective was to understand the effect of all cutting parameters on the tool wear behavior and stability of the cutting process. The investigations were focused on the mechanisms of the chip formation process and their interaction with tool wear. At the microstructure scale, the analysis confirms the intense deformation of the machined surface and shows a texture modification. As the cutting speed increases, cutting forces and temperature show different progressions depending on the considered microstructure (Ti-6Al-4V or Ti-55531 alloy). Results show for both materials that the wear process is facilitated by the high cutting temperature and the generation of high stresses. The analysis at the chip-tool interface of friction and contact nature (sliding or sticking contact) shows that machining Ti55531 often exhibits an abrasion wear process on the tool surface, while the adhesion and diffusion modes followed by the coating delamination process are the main wear modes when machining the usual Ti-6Al-4V alloy.
Sulfonation Process and Desalination Effect of Polystyrene/PVDF Semi-Interpenetrating Polymer Network Cation Exchange Membrane
Authors: Lei Yin-lin , Luo Yun-jie , Chen Fei , Mei Le-he
Published: July 2014

With the classical sulfonation method of polystyrene-based strongly acidic cation exchange resins, polystyrene/polyvinylidene fluoride (PVDF) alloy particles were sulfonated to obtain a cation exchange resin, which was then directly thermoformed to prepare a semi-interpenetrating polymer network (semi-IPN) cation exchange membrane. The effects of the swelling agent, sulfonation time and temperature and the relative contents of polystyrene and divinylbenzene (DVB) in the alloy particles on the feasibility of the membrane formation are discussed. The results indicate that a favorable sulfonation degree above 80% and a suitable ion exchange capacity of 1.5–2.4 mmol/g can be gained, with concentrated sulfuric acid as the sulfonation agent and 1,2-dichloroethane as the swelling agent. The running electrical resistance and desalination effect of the prepared cation exchange membrane were measured in a pilot-scale electrodialyser and not only obviously exceeded a commercial heterogeneous cation exchange membrane, but was also very close to a commercial homogenous membrane. In this way, the authors have combined the classical sulfonation method of polystyrene-based cation exchange resins with the traditional thermoforming manufacturing process of heterogeneous cation exchange membranes, to successfully develop a novel, low-price, but relatively high-performance polystyrene/PVDF cation exchange membrane with the semi-IPN structure.
A Comparison of Advanced Regression Algorithms for Quantifying Urban Land Cover

Published: July 2014

Quantitative methods for mapping sub-pixel land cover fractions are gaining increasing attention, particularly with regard to upcoming hyperspectral satellite missions. We evaluated five advanced regression algorithms combined with synthetically mixed training data for quantifying urban land cover from HyMap data at 3.6 and 9 m spatial resolution. Methods included support vector regression (SVR), kernel ridge regression (KRR), artificial neural networks (NN), random forest regression (RFR) and partial least squares regression (PLSR). Our experiments demonstrate that both kernel methods SVR and KRR yield high accuracies for mapping complex urban surface types, i.e., rooftops, pavements, grass- and tree-covered areas. SVR and KRR models proved to be stable with regard to the spatial and spectral differences between both images and effectively utilized the higher complexity of the synthetic training mixtures for improving estimates for coarser resolution data. Observed deficiencies mainly relate to known problems arising from spectral similarities or shadowing. The remaining regressors either revealed erratic (NN) or limited (RFR and PLSR) performances when comprehensively mapping urban land cover. Our findings suggest that the combination of kernel-based regression methods, such as SVR and KRR, with synthetically mixed training data is well suited for quantifying urban land cover from imaging spectrometer data at multiple scales.
A Low-Cost Real Color Picker Based on Arduino
Authors: Agudo Juan , Pardo Pedro , Sánchez Héctor , Pérez Ángel , Suero María
Published: July 2014

Color measurements have traditionally been linked to expensive and difficult to handle equipment. The set of mathematical transformations that are needed to transfer a color that we observe in any object that doesn’t emit its own light (which is usually called a color-object) so that it can be displayed on a computer screen or printed on paper is not at all trivial. This usually requires a thorough knowledge of color spaces, colorimetric transformations and color management systems. The TCS3414CS color sensor (I2C Sensor Color Grove), a system for capturing, processing and color management that allows the colors of any non-self-luminous object using a low-cost hardware based on Arduino, is presented in this paper. Specific software has been developed in Matlab and a study of the linearity of chromatic channels and accuracy of color measurements for this device has been undertaken. All used scripts (Arduino and Matlab) are attached as supplementary material. The results show acceptable accuracy values that, although obviously do not reach the levels obtained with the other scientific instruments, for the price difference they present a good low cost option.
On the Network Convergence Process in RPL over IEEE 802.15.4 Multihop Networks: Improvement and Trade-Offs
Authors: Kermajani Hamidreza , Gomez Carles
Published: July 2014

The IPv6 Routing Protocol for Low-power and Lossy Networks (RPL) has been recently developed by the Internet Engineering Task Force (IETF). Given its crucial role in enabling the Internet of Things, a significant amount of research effort has already been devoted to RPL. However, the RPL network convergence process has not yet been investigated in detail. In this paper we study the influence of the main RPL parameters and mechanisms on the network convergence process of this protocol in IEEE 802.15.4 multihop networks. We also propose and evaluate a mechanism that leverages an option available in RPL for accelerating the network convergence process. We carry out extensive simulations for a wide range of conditions, considering different network scenarios in terms of size and density. Results show that network convergence performance depends dramatically on the use and adequate configuration of key RPL parameters and mechanisms. The findings and contributions of this work provide a RPL configuration guideline for network convergence performance tuning, as well as a characterization of the related performance trade-offs.
An Electrochemical Impedimetric Aptasensing Platform for Sensitive and Selective Detection of Small Molecules Such as Chloramphenicol
Authors: Pilehvar Sanaz , Dierckx Tarryn , Blust Ronny , Breugelmans Tom , De Wael Karolien
Published: July 2014

We report on the aptadetection of chloramphenicol (CAP) using electrochemical impedance spectroscopy. The detection principle is based on the changes of the interfacial properties of the electrode after the interaction of the ssDNA aptamers with the target molecules. The electrode surface is partially blocked due to the formation of the aptamer-CAP complex, resulting in an increase of the interfacial electron-transfer resistance of the redox probe detected by electrochemical impedance spectroscopy or cyclic voltammetry. We observed that the ratio of polarization resistance had a linear relationship with the concentrations of CAP in the range of 1.76–127 nM, and a detection limit of 1.76 nM was obtained. The covalent binding of CAP-aptamer on the electrode surface combined with the unique properties of aptamers and impedimetric transduction leads to the development of a stable and sensitive electrochemical aptasensor for CAP.
Software for Correcting the Dynamic Error of Force Transducers

Published: July 2014

Software which corrects the dynamic error of force transducers in impact force measurements using their own output signal has been developed. The software corrects the output waveform of the transducers using the output waveform itself, estimates its uncertainty and displays the results. In the experiment, the dynamic error of three transducers of the same model are evaluated using the Levitation Mass Method (LMM), in which the impact forces applied to the transducers are accurately determined as the inertial force of the moving part of the aerostatic linear bearing. The parameters for correcting the dynamic error are determined from the results of one set of impact measurements of one transducer. Then, the validity of the obtained parameters is evaluated using the results of the other sets of measurements of all the three transducers. The uncertainties in the uncorrected force and those in the corrected force are also estimated. If manufacturers determine the correction parameters for each model using the proposed method, and provide the software with the parameters corresponding to each model, then users can obtain the waveform corrected against dynamic error and its uncertainty. The present status and the future prospects of the developed software are discussed in this paper.

Published: July 2014

Purpose: To compare the diagnostic accuracy of magnetic resonance imaging (MR-lym- phangiography) and lymphoscintigraphy for assessment of focal lesions of the peripheral lymphatic system. Patients with focal lymphatic transport disorders might benefit from surgi-cal interventions. Patients, methods: We examined by lymphoscintigraphy and MR- lymphangiography a total of 85 lower limbs in 46 consecutive patients (33 women; mean age 41 years; range 9-79 years) presenting with uni- or bilateral lymphedema. MR-lym- phangiographies were obtained at isotropic sub-millimeter resolution with a 3.0 Tesla magnet after injection of gadolinium contrast medium. MR-lymphangiography was reviewed by radiologists, whereas lymp- hoscintigraphy was reviewed by nuclear medicine physicians. The images were examined for localization and distribution of any focal lesions of the lymphatic vessel system. Diagnostic accuracy of the MR-approach was calculated relative to the lymphoscintigraphy gold standard. Results: There was substantial correlation of results by the two modalities (κ = 0.62). MR-lymphangiography had sensitivity of 68%, specificity of 91%, positive predictive value of 82%, and negative predictive value of 83%. Conclusions: Imaging findings of both lymphoscintigraphy and MR-lymph- angiography showed good diagnostic accuracy. MR-lymphangiography proved more information about anatomic location of focal lesions of the lymphatic vessels, but use of MR-lymphangiography is currently constrained due to the requirement for off-label subcutaneous injection of gadolinium che- lates. Consequently, and due to its superior sensitivity lymphoscintigraphy remains the most common imaging method to assess functional lymphatic disorders of the lower limb.

Published: July 2014

Energy saving has become one of the foremost priorities in the European Union and a great deal of attention is directed towards the sector of sustainable building. However, the EU members that have an extensive Soviet heritage now face a great difficulty in reducing energy consumption. Since many apartment buildings are in especially poor thermal condition, and the heat supply infrastructure is morally and physically outdated, energy consumption for heating is significant. The modernization (renovation) of such old buildings is impeded not only by legal and technical factors, but also financial and social aspects in regard to the residents. Thus, this paper provides new model of investments and modernization of apartment buildings on the basis of the calculation of energy input per one degree-day of the heated floor area. The presented degree-days calculation method enables the calculation and inter-comparison of data gathered in all European Union member states without taking into account specific climate parameters of each.
Outcomes of a Quality Improvement Project for Educating Nurses on Medication Administration and Errors in Nursing Homes
Authors: Tenhunen Monica L. , Tanner Elizabeth K. , Dahlen Rebecca
Published: July 2014

Background:

The Institute of Medicine has provided recommendations for preventing medication errors in nursing homes that include nursing education. Support for education on medication administration is derived from evidence, primarily in settings other than nursing homes. This quality improvement project implemented an educational program for licensed nurses to increase knowledge of medication administration and to decrease medication-related errors.

Method:

A descriptive study of 72 licensed nurses in two nursing homes was used for this project. Medication resources were provided at nursing stations in both facilities. Licensed nurses took a pretest and then watched a 35-minute education presentation. One month later, they took a posttest.

Results:

Percentage scores on the tests were calculated. Paired
t
tests demonstrated an increase in nursing knowledge in one facility (
p
= 0.04) and no significant increase in nursing knowledge in the second.

Conclusion:

Mandatory participation by all staff members who administer medications would increase participation in the project. Multiple factors influence knowledge and medication administration in nursing homes and need further study.

Transient Ileus Associated With the Use of Mydriatics After Screening for Retinopathy of Prematurity in a Very Low Birth Weight Infant
Authors: Degirmencioglu Halil , Oncel Mehmet Yekta , Calisici Erhan , Say Birgul , Uras Nurdan , Dilmen Ugur
Published: July 2014

Very low birth weight (VLBW) infants have ophthalmologic examinations for retinopathy of prematurity (ROP) prior to discharge, with appropriate follow-up and intervention where appropriate. Eye drops such as cylopentolate, tropicamide, and phenylephrine are used at different concentrations to provide proper pupil dilation for screening ROP. Topical instillation of eye drops may cause mild or severe ocular or systemic adverse effects. Early recognition of systemic toxicity after eye drop instillation is important. The authors present a case of a VLBW infant who developed significant abdominal symptoms (mimicking ileus) that were significant enough to discontinue oral feeding after ocular instillation of 0.5% tropicamide and 2.5% phenylephrine eye drops for routine examination of ROP. After structural and functional gastrointestinal disorders and sepsis were excluded, symptoms resolved completely after discontinuation of the drug. This report is thought to be the first in the medical literature to address 5% tropicamide and 2.5% phenylephrine eye drops, and the combination that may lead to serious complication after ROP examinations.

Between utilitarian and autonomous: Polish opera in the second half of the nineteenth century
Authors: Zieziula Grzegorz
Published: July 2014

The Warsaw premiere of Moniuszko’s Halka (1858) opened the way to more ambitious operatic works in Poland. Operas written towards the end of the century, among them Livia Quintilla by Zygmunt Noskowski and Philaenis by Roman Statkowski, were deliberate statements of artistic autonomy. They prepared the ground for the operatic compositions of the generation of Karol Szymanowski.

Published: July 2014

The article combines the current methodical concepts of “cultural transfer” and “spatial sociology” in research into “Iacobus Handl Gallus dictus Carniolus”. Josef Mantuani, Dragotin Cvetko and other musicologists have mentioned Görlitz as a site for the reception of works by Jacob Handl (Händl in Lusatian sources), but no one has hitherto discussed the transcultural region of Upper Lusatia. Beside the printed motets a number of pieces from Handl’s Opus musicum have been preserved in manuscripts that originate from Görlitz, Löbau and Kamenz.

Didone by Cavalli and Busenello: from the sources to modern productions
Authors: Fabris Dinko
Published: July 2014

Didone was the second significant operatic project carried out by the librettist Busenello and the composer Cavalli. However, its importance has until recently been underestimated. One of several misunderstandings is that the only extant score has erroneously been considered to be related to the Venetian premiere of the opera in 1641. Following the comparison of all surviving sources – including a previously unknown exemplar of the libretto printed in Naples – it is now possible to relate the Venetian score to the Neapolitan performance in 1650.
Two antiphonals from the Charthusian monastery in Žiče: Manuscripts 273 and 7 from the Graz University Library
Authors: Šter Katarina
Published: July 2014

The Carthusian monastery in Žiče (Ger. Seitz) played a central role in the history of the Carthusian Order during the turbulent period of the Great Schism, which might have also influenced its musical life. A comparison of the texts, melodies, and note groupings in two Žiče antiphonals from the 13th and 15th centuries, as well as some other facts about music in the other Carthusian monasteries of that time, can offer at least a vague picture of the musical life at the Žiče monastery in the fiftheenth century.
Palestrina’s Vestiva i colli as a model for the parody process in Gabriello Puliti’s early works
Authors: Lovrinić Nikola
Published: July 2014

A wide range of compositional styles used by Gabriello Puliti (c. 1580–1644) in his earliest printed collections from the turn of the century undoubtedly reflect his basic musical training. His application of a variety of styles to a single musical genre – motet or vesper psalms – can also possibly be seen as practice in the art of composition. Among the principles employed by Puliti, parody is especially interesting. In his motet En dilectus meus, included in the collection Sacrae modulationes (1600), Puliti interpolated a theme from Palestrina’s madrigal Vestiva i colli (1566). Puliti’s own completely homophonic opening is followed by a literal quotation of the first part of Palestrina’s madrigal transposed a fifth downward with some slight deviations from the original in rhythm required to fit the music to different words.
The early keyboard concertos in Ptuj: music composed for the Dornava court?
Authors: Eybl Martin
Published: July 2014

The 31 keyboard concertos now housed at the Knjižnica Ivana Potrča Ptuj represent a unique sample of early keyboard concertos in Central Europe, including works by the Viennese court composers Georg Christoph Wagenseil (1714–1777) and Wenzel Raimund Birck (1718–1763) as well as two musicians employed at the Graz parish church, Johann Michael Steinbacher (before 1710–after 1740) and Giovanni Antonio Sgatberoni (1708/09–1795). It is assumed that the Ptuj collection of keyboard music stems from the court of Count Joseph Bernhard von Attems, who resided at Dornava from 1754 to 1772. Considering the scribes and the paper quality of the sources, it seems possible that Steinbacher and Sgatberoni may have had a closer relationship to the Dornava court than has been assumed so far.

Mean surface geostrophic ocean currents may be calculated from the Mean Dynamic Topography (MDT), estimated as the difference between a mean sea surface height (MSS) calculated from radar altimeters and a reference geoid height. A review of the most widely used geoids is presented. The difference between the third release of the Gravity field and steady-state Ocean Circulation Explorer (GOCE) geoid and three earlier geoids (the Earth Geopotential Model 1996 [EGM96], one of the geoids obtained by the Gravity Recovery and Climate Experiment [GRACE05], and the Earth Gravitational Model 2008 [EGM2008]) is computed and interpreted as an ‘artefact’ MDT, i.e. a misfit when non-accurate geoid models are used to calculate the ocean MDT and related geostrophic currents. These results are contrasted with the MDT computed by comparing the GOCE geoid with the MSS distributed by Collecte Localisation Satellites in 2001 (CLS01). The comparison shows that there was a strong influence of altimetry measurements in the construction of the EGM96 geoid, i.e. the artefact MDT calculated using EGM96 shows a high resemblance to the MDT computed using the MSS CLS01 field, both considering GOCE as the reference geoid. The correlation disappears largely, but not completely, for the two most recent geoids; in particular, the MSS has greater global influence on GRACE05 than on EGM2008 although the latter does better at latitudes of less than 60° and is more useful for reproducing the intense western boundary currents. The results show that EGM96 may lead to significant errors in the spatial gradients of MDT (for latitudes of less than 60° the global root mean square is 0.2422 m) and therefore in the geostrophic surface velocities. When the spatially averaged GRACE and EGM2008 geoids are used for latitudes of less than 60°, the global MDT root mean square is substantially reduced.

Understanding solar movement (e.g., solar diurnal motion) is difficult for those are beginning to learn about astronomy. Previous research has revealed that observation-based learning can help make astronomical phenomena clearer to understand for such learners. In this research, Smartphone Augmented Reality (AR) technology and 3D content were used to develop a multi-viewpoint Smartphone AR-based learning system (M-VSARLS) for solar movement observations that can be used in the real-world environment. The goal of this research is to assess the usefulness of the system, usability of the AR function and 3D content, and the overall effect of the system on the learner’s motivation through task-based experiments with follow-up questionnaires. The results show that the M-VSARL system is effective in improving the observational skills and learning ability of learners, and in enhancing their motivation to learn about solar movement.

Published: July 2014

In future multimedia systems, seamless access to application services on different devices available to users in their vicinity, will be commonplace. The availability of these services will change as the mobile user moves. Current 3G multimedia systems do not support access to multiple applications operating on multiple different devices in context of a session or indeed seamless device session handover. Considering these requirements, the authors outline two multimedia communication platforms which potentially solve this problem. This paper describes a backward compatible architecture based on the widely adopted Session Initiation Protocol (SIP) and also outlines a clean slate approach from ITU-T SG 16 called the Advanced Multimedia System (AMS). For each of these solutions the paper describes in terms of architecture, signalling, and capability negotiation, what are viewed as the most critical functions in future multimedia systems design. The result of this comparison displays the advantages and disadvantages of each approach, and outlines solutions to satisfy challenges of current and future multimedia systems based on the service access requirement in ubiquitous environments. Furthermore, this comparison is used to suggest approaches that are best suited for future multimedia system design.

IT-ASSIST is a twenty months research project which has the goal to give elderly people the opportunity to profit from digital media. Suffering from age related impairments concerning vision, hearing, or dexterity and bad hand-eye coordination are challenges when designing user interfaces for elderly people. Common approaches are trying to model systems for specific impairments. In this project, the authors follow the approach to set up interfaces and systems that can be used independent from personal impairments. Customization has adapted these systems to be in accordance with personnel impairments. Common applications like photo editing, digital mailing or internet browsing in a redesigned form provide social communication accordingly. In this article, a prototype of a customized user interface, its implementation, and results of user studies are presented and discussed.

The HERMES Cognitive Care and Guidance for Active Aging project proposes an integrated approach to cognitive assistance, promoting the autonomy of elderly users through pervasive technology. This work aims to describe elderly people’s opinions when they are presented scenarios developed in this project. Two focus groups were organized in Austria and Spain with a view to collecting their impressions about the way in which the technological device can cover their needs; complementarily, a second session was conducted including a quantitative questionnaire. Although some participants were reluctant to use the technology, they welcomed some functionalities of the HERMES system and they considered that using them can help them to become familiar with them. Usefulness, usability, and use of real-life information for functionalities such as cognitive games are considered to be key areas of the project. This evaluation has provided the developers of the system with meaningful information to improve it and it guarantees that the system addresses elderly people’s needs.

Published: July 2014

An Augmented Reality (AR) is a technology which provides the user with a real time 3D enhanced perception of a physical environment with addition virtual elements—either virtual scenery, information regarding surroundings, other contextual information—and is also capable of hiding or replacing real structures. With Augmented Reality applications becoming more advanced, the ways the technology can be viably used is increasing. Augmented Reality has been used for gaming several times with varying results. AR systems are seen by some as an important part of the ambient intelligence landscape. Therefore, the authors present several types of augmentation applications of AR in the domestic, industrial, scientific, medicinal, and military sectors which may benefit future ambient intelligent systems.
