Authors: Cristina Blesneac , Theodora Benedek , Rodica Togănel , I Benedek 
Published: March 2014

Abstract Background: Hypertrophic cardiomyopathy, one of the most common inherited cardiomyopathies, is a heterogeneous disease resulting from sarcomeric protein mutations, with an incidence in the adult population of 1:500. Current information on the epidemiology and outcomes of this disease in children is limited. Methods: Thirty-four children diagnosed with hypertrophic cardiomyopathy in the Pediatric Cardiology Department from Tîrgu Mureș were evaluated concerning familial and personal history, clinical, paraclinical and therapeutic aspects. Hypertrophic cardiomyopathy was defined by the presence of a hypertrophied, non-dilated ventricle, in the absence of a cardiac or systemic disease that could produce ventricular hypertrophy. Results: The youngest diagnosed child was a neonate, a total of 10 patients being diagnosed until 1 year of age. In 6 cases a positive familial history was found. Noonan syndrome was found in 2 cases. Only 21 patients were symptomatic, the predominant symptoms being shortness of breath on exertion with exercise limitations. Left ventricular outflow tract obstruction was present in 21 cases (61.7%). Twenty-four patients were on β-blocking therapy, while 4 patients underwent septal myectomy. Conclusions: Hypertrophic cardiomyopathy is a heterogeneous disorder in terms of evolution, age of onset, type and extent of hypertrophy, and the risk of sudden death. It can affect children of any age. There is a need for a complex evaluation, including familial and personal anamnesis, clinical examination, electrocardiogram and echocardiography of all patients. It is highly important to develop screening strategies, including genetic testing, for an early diagnosis, especially in asymptomatic patients with a positive familial background

Abstract
Aim: The aim of this study was to compare the periodontal status of impacted canines after 5 years following completion of the combined surgical and orthodontic treatment. Materials and methods: We examined 20 labially impacted canines and 20 palatally impacted canines at 5 years after the end of treatment. We assessed the periodontal status of these teeth. Results: Different outcomes were found regarding the probing depth and the amount of keratinized gingiva in the two mentioned groups of teeth. Conclusions: The assessed periodontal indices may signal the appearance of a periodontal disease around the teeth that were surgically and orthodontically treated

Published: March 2014

Abstract
Background: In the literature there are a number of studies that suggest a possible correlation between cholelithiasis/cholecystectomy and colorectal cancer. The exposure of the colon mucosa to the action of bile acids that potentially have a carcinogenic effect due to the change in anatomy after cholecystectomy, seems to be the explanation of this association. The purpose of this paper was to search for such a correlation in our study group. Methods: We performed a retrospective cross-sectional study, analyzing the patients admitted to the First Surgical Clinic of the County Emergency Clinical Hospital Tîrgu Mureș, between January 1st, 2005 - December 31st, 2010. Analyzing the medical records, operation protocols and histopathological results, we paid attention to demographics, location of neoplasia, the time elapsed since the cholecystectomy to the discovery of neoplasia, histological types, trying to perform correlations between these parameters and the lithiasic factor. Results: Out of the 534 patients admitted and operated with the diagnosis of colorectal cancer, 15.6% (n = 83) showed a history of gallbladder stone affection. Most patients came from urban areas, the average age was 67.2 (range 39-88 years), females were more affected. The most common locations were: the sigmoid colon (26.5%), rectum (36.3%) and the most common histological form was moderately differentiated adenocarcinoma. Conclusions: Similar to other studies, our work suggests a slight increase in the incidence of colorectal cancer in patients that underwent a cholecystectomy, without drawing a firm conclusion. We deem it necessary to see if diet changes of the Romanian population affect this relationship
Analysis of performance bottleneck of P2P grid applications
Authors: Šimon Marek , Huraj Ladislav , Siládi Vladimír 
Published: March 2014

Abstract
The OurGrid distributed environment is an open source grid middleware that enables the creation of P2P computational grids to speed up the execution of bag-of-tasks applications. Bag-of-tasks is an application model composed of several independent tasks not communicating with each other during their execution, tolerating network delays and faults. The paper shows that the main advantage to avoid bottlenecks is if the data gets larger or computations become more complex and the conclusion is made based on the presented measurements. Understanding such patterns sheds an insightful light on performance bottlenecks and design tradeoffs for P2P Grid applications

Animating multiple interacting miscible and immiscible fluids based on particle simulation
Authors: Onderik Juraj , Chládek Michal , Ďurikovič Roman 
Published: March 2014

Abstract
We present a particle-based approach for animating multiple interacting liquids that can handle number of immiscible fluids as well as number of miscible fluids in our simulation framework. We solve the usual problem of robust interface tracking, between immiscible fluids, by reconstructing the zero level set of our novel composite implicit function, see Fig. 1 left and center. It’s recurrent formulation handles directly interfaces between any number of liquids including the free surfaces. We model the miscible fluids by tracking concentrations of dissolved materials in the vicinity of each particle. Flick’s law is applied for the Laplacian-based diffusion of concentrations, see Fig. 1 right. Particle sedimentation is achieved by directional advection along the settling velocity. The diffusion-advection equation is discretized by particles using the Lagrangian formulation. The proposed improvements can be easily implemented into the common Smoothed Particle Hydrodynamics (SPH) simulations framework
Experimental verification of numerical simulation of projectile impact on ballistic shields
Authors: Zatorski Zdzisław 
Published: March 2014

Abstract
In this work, the author presents experimental verification of numerical simulation of projectile impact on constructional shields. The experimental tests were performed at a unified test stand to investigate ballistic resistance of materials in field conditions. The stand was developed at the Polish Naval Academy in Gdynia, and then patented. The design of this test stand was based on construction of a ballistic pendulum, fitted to measure: impact force, turn angle of the ballistic pendulum x, impact velocity and residual velocity of the projectile. All the measurement data were transmitted to a digital oscilloscope and a personal computer. The ballistic velocity of the shield of VBL(R) - defined according to Recht’s and Ipson’s method, was compared with V BL(Z) and VBL(Z1) - determined according to the author’s method. Verification of numerically simulated ballistic velocity VRO versus the before-mentioned velocity was carried out at the 10GHMBA-E620T steel shields impacted by 12.7 mm type B- 32 projectiles. The introduced method can be used for determining ballistic thickness hBL and ballistic velocity VBL for both homogeneous plates as well as multi-layered constructional shields

Authors: Horňák Marcel , Pšenka Tomáš , Križan František 
Published: March 2014

Abstract
The long-distance public transport services among the eight regional centres of Slovakia, representing the key urban locations with concentrations of most of the country’s services, including business, educational and financial institutions, as well as political power, are examined in this article. It is assumed that the mutual transport interconnections within this group of cities will be a focus for public transport operators in their attempt to gain the largest possible share of potential customers, passengers who would otherwise be users of individual transport means. Hence, one of main aims of this study is to compare public and individual transport modes, and the possibilities offered by them in the mutual interconnections of major regional centres in the country
Stakeholders' Arguments for and against Moving Swedish Substance abuse Treatment to the Health Care System: How a Fat Reform Proposal became a Thin Government Bill
Authors: Storbjörk Jessica 
Published: March 2014

Background Far-reaching changes in the Swedish substance abuse treatment system (SAT) were proposed by a state-commissioned inquiry in 2011. The proposal implied a break with the social tradition of SAT. It was suggested that the treatment responsibility should be transferred from the municipal social services to the regional-level health care system; and that compulsory treatment in its present form (assessed by/paid for by social services, run by the state) should be abolished and become incorporated into coercive psychiatric care provided by health care. A lively debate arose, and the vast majority of stakeholders sought to articulate their arguments. Aim The study analysed the development of Swedish SAT by examining the policy process from reform proposal to government bill in 2013. Method Content analysis was used to analyse written comments on the proposal submitted to the Ministry of Health and Social Affairs by close to 200 stakeholders. The goal was to empirically chart and examine the arguments for and against as well as advocates and opponents of the reform. With the government bill at hand, we retrospectively sorted out the winning arguments in the now highly contested SAT field and which actors were able to influence the process. Conclusions The article discloses that the mixed response and rather critical voices in most groups, including social/medical professions and government bureaucracy, helped block the responsibility shifts, and that reformations of subsystems like SAT are difficult to carry out as freestanding projects within larger systems of social and health care.
A relativistic wave equation with a local kinetic operator and an energy-dependent effective interaction for the study of hadronic systems
Authors: Sanctis Maurizio 
Published: March 2014

AbstractWe study a fully relativistic, two-body, quadratic wave equation for equal mass interacting particles. With this equation the difficulties related to the use of the square roots in the kinetic energy operators are avoided. An energy-dependent effective interaction, also containing quadratic potential operators, is introduced. For pedagogical reasons, it is previously shown that a similar procedure can be also applied to the well-known case of a one-particle Dirac equation. The relationships of our model with other relativistic approaches are briefly discussed. We show that it is possible to write our equation in a covariant form in any reference frame. A generalization is performed to the case of two particles with different mass. We consider some cases of potentials for which analytic solutions can be obtained. We also study a general numerical procedure for solving our equation taking into account the energy-dependent character of the effective interaction. Hadronic physics represents the most relevant field of application of the present model. For this reason we perform, as an example, specific calculations to study the charmonium spectrum. The results show that the adopted equation is able to reproduce with good accuracy the experimental data.
Interdisciplinary study on pottery experimentally impregnated with wine

Published: March 2014

AbstractExperimentally developed ceramic pots, with two different sizes of grain, were half-filled with wine and subjected to thermal alteration at constant elevated temperature ((60 ± 2)°C) in darkness for 12 weeks. This work sought to characterise the samples thereby obtained from chemical and mineralogical perspectives using scanning electron microscopy and an energy-dispersive X-ray microanalysis system (SEM-EDX), Fourier transform infrared spectroscopy (FTIR) and capillary electrophoresis (CE) with UV detection as an alternative to chromatographic methods, due to its good resolution, automation, simplicity, high speed, low consumption of chemicals and short time required for sample preparation. The capillary electrophoresis method was used for the detection of five wine biomarkers: succinic acid, malic acid, tartaric acid, citric acid and lactic acid. In general, it was noted that the fine-grained ceramic assortment retained the organic material better than the coarser-grained ceramics. An interesting observation derived from this study was that not only could tartaric acid be considered as a biomarker for wine residues in archaeological pottery, but malic acid could also act similarly for white wine and lactic acid for red wine.

Published: March 2014

Introduction This study will examine the effects of combined aerobic and resistance training on left ventricular remodeling in diabetic patients with diastolic dysfunction. This is the first randomized controlled trial to look for effects of combined strength training and aerobic exercise on myocardial function as well as other clinical, functional, or psychological parameters in diabetic patients with isolated diastolic dysfunction, and will provide important insights into the potential management strategies for heart failure with preserved ejection fraction. Methods and Analysis This is a prospective, randomized controlled investigator initiated single center trial. Diabetic patients with LV diastolic dysfunction suitable for exercise training intervention will be randomized to three months of a supervised combination of aerobic and strength training exercises, or supervised light stretching (control arm). Pre and post intervention assessment will include stress echocardiography, peak aerobic power with 12-lead ECG, dual-energy X-ray absorptiometry, muscle strength, the capacity to perform activities of daily living (ADLs), and questionnaires to assess self-perceived quality of life and symptoms of depression. The primary endpoint is to compare any change in tissue Doppler-derived LV systolic and early diastolic velocities. Ethics and Dissemination The current trial protocol has been approved by the Human Research Ethics Committee of Austin Health and the University of Melbourne, Melbourne. The study will be performed in accordance with the Declaration of Helsinki. The investigator, regardless of the outcome, will publish the results of the study.

A Cross-Cultural Study on Hedging Devices in Kurdish Conversation
Authors: BEHNAM Biook , KHALILIAQDAM Salam 
Published: March 2014

Hedges are words whose job is to make things fuzzier or less fuzzy. Truth and falsity are a matter of degree, and hedges make natural language sentences more/less true or more/less false. The purpose of the study is to investigate hedging devices in Kurdish spoken language. The aim is to know how hedging devices are used in Kurdish spoken discourse. Also the researchers are willing to know whether Kurdish speakers use hedging devices to indicate a lack of complete commitment to the truth of the proposition, and a desire not to express the commitment categorically, or to lessen the impact of an utterance. The data needed for the study was collected through observation, tape recording, and interviews. The dialogues of 35 people were recorded by the researchers as well as the researchers have interviewed with 21 people from different social classes.15 classes and meetings which Kurdish language was the means of communication were observed. The research showed that hedging as a mitigating device is extensively employed in different conversations. The study shows that hedging devices have the same roles in Kurdish as they have in English. They are used to reduce the certainty and sureness of the utterances. It indicates that some pragmatic devices modify the epistemic strength of the statement in Kurdish language just as they do in English and Arabic.
Input Method "Five Strokes": Advantages and Problems
Authors: PETROVČIČ Mateja 
Published: March 2014

Five Stroke “Wubi Hua” is an input method, based on the stroke shape and stroke order of a character, and requires only 5 keys from 1 to 5 on numerical keypad to input every character. As an input method for Chinese, it is already integrated in Mac OS X, and is available as part of different applications for Windows OS. Although stroke order in Chinese and Japanese is different to some extent, this input method can be applied to characters of both writing systems.
Since the Five Stroke input method is easily accessible, simple to master and is not pronunciation-based, we would expect that the students will use it to input unknown characters. The survey comprises students of Japanology and Sinology at Department of Asian and African Studies, takes in consideration the grade of the respondent and therefore his/her knowledge of characters. This paper also discusses the impact of typeface to the accuracy of the input.
Denitrification alternates between a source and sink of nitrous oxide in the hypolimnion of a thermally stratified reservoir

Published: March 2014

Nitrogen loading from developed watersheds to aquatic ecosystems can stimulate microbial denitrification, a process that reduces nitrate (NO−3) to dinitrogen (N2) or nitrous oxide (N2O), the latter a potent greenhouse gas. While aquatic ecosystems are a globally significant source of N2O to the atmosphere, the relationship between denitrification and N2O production is not well known. Until recently, this field of research has been limited by the technical challenges of simultaneously measuring denitrification and N2O production or consumption in situ at the ecosystem scale. Here we use membrane inlet mass spectrometry, an analytical method providing precise and accurate measurements of dissolved N2, and gas chromatography to directly measure N2 and N2O concentrations in the hypolimnion of a stratified reservoir draining an agricultural watershed. Denitrification resulted in a consistent increase in dissolved N2 and decrease in NO−3 concentrations in the hypolimnion during the 5 month period of stratification, though temporal patterns in dissolved N2O concentrations were less consistent. Denitrification alternated between an N2O source and sink, with the N2O yield, defined as the relative production of N2O to N2 via denitrification, ranging from −3.4% (i.e., net N2O consumption) to 19.5% (mean = −0.03%). Whereas denitrification in the hypolimnion functioned as a small N2O sink during the stratified period, the reservoir was an N2O source on an annual time scale. Additional studies across reservoirs of different sizes, trophic status, and ages are needed to resolve the role of reservoirs in the global N2O budget.
Aggregation as a function of and mineral particles
Authors: Passow Uta , De La Rocha Christina L. , Fairfield Caitlin , Schmidt Katrin 
Published: March 2014

A laboratory experiment was designed to investigate the effects of ocean acidification (three levels) in the presence or absence of the clay mineral illite (five concentrations) on the coagulation of organic particles. The formation of aggregates > 1 mm from marine detritus and phytoplankton, and their characteristics and sinking velocity, were monitored during the 48 h experiment. Aggregation of particulate organic carbon (POC) was independent of both partial pressure of carbon dioxide (PCO2) and illite addition, implying that the fraction of POC available for export is not affected by either mineral supply or ocean acidification conditions up to ambient + 52.7 Pa PCO2 (+ 520 ppm). This was true even though the illite appreciably influenced aggregate size, number, and characteristics, including the percentage of transparent exopolymer particles (TEP) incorporated in aggregates. Carbonate chemistry, in the presence of illite, did affect particle formation by clay, carbon, and TEP at the micrometer scale (allocation between dissolved and particulate pools). Our experiment did not resolve processes on this scale well and it remains to be seen if such shifts in the size spectrum of organic carbon and minerals are relevant for the biological pump. High illite content led to small aggregates with a low average sinking velocity. In the absence of biological changes to particle production or loss, coagulation of POC, which is central to the biological pump, is not influenced by ocean acidification or dust input, but sinking velocity and, hence, flux attenuation of POC are likely to be affected by changes in dust input.
