Objective:Hydrosurgical debridement allows removal of non-viable tissue, preserving healthy tissues. This study was designed to analyse whether hydrosurgery, used in a clinical wounds unit, is an effective and safe method that may reduce debridement time.Methods:Patients' wounds had the following characteristics: wounds with devitalised tissue needing rapid debridement, wounds with cavities, or non-healing wounds. Hydrosurgical debridement uses a pressurised stream of saline (0.9% sodium chloride) and a vacuum around this stream to remove the devitalised tissue of the wound, preserving healthy surrounding tissues.Results:This prospective study comprised of 53 wounds from 39 patients. The wound aetiology included 39.7% arterial insufficiency, 22.6% pressure ulcers (PUs), 15.1% diabetic foot ulcers (DFUs), 9.4% venous leg ulcers (VLUs), and 13.2% from other aetiologies. The percentage of wounds according the size was the following: 32.1% (<10cm2), 43.4% (10–49cm2), 15.1% (50–99cm2), and 9.4% (≥100cm2). Superficial wounds were 43.4% of the total and 56.6% of wounds had cavities. Pain associated with the hydrosurgery was mild to moderate. There were no hydrosurgery-related adverse events. For effective debridement, the required sessions were as follows: one procedure (73.6%), two procedures (18.9%) and three procedures (7.5%). There was a statistical significant direct correlation (r=0.307) between the number of required sessions and wound size. All patients improved in a week (>80% of granulation tissue).Conclusion:We demonstrate that hydrosurgery is an effective and rapid debridement method that can be used safely in the outpatient setting.

Published: October 2017

Objective: This compares hospital suction negative pressure wound therapy (NPWT) with conventional gauze dressings in traumatic soft-tissue injury at a tertiary care centre. Methods: A prospective control study was conducted between September 2012 and November 2014. Patients with one or more traumatic soft-tissue injuries with contaminated wounds were allocated to either a test group (received NPWT) or control group (received conventional gauze). Wounds were assessed by two orthopaedic surgeons. If grade A was achieved, the wound was covered with split-thickness skin graft, flap or delayed primary closure; otherwise, revision debridement and NPWT/saline gauze dressings were applied. Descriptive statistics (mean, standard deviation and proportions) were used to summarise the study variables. The 95% confidence intervals (CI) for difference of mean were used. Chi-square test and Fisher's exact test were used to observe an association between the qualitative data and outcome variables. Unpaired T-Test and Mann–Whitney U test were used for analysis of the quantitative data. A p<0.05 was considered statistically significant. Results: A total of 104 patients were included. The mean number of dressings per patient was significantly lower in the NPWT group (3.4) than in the control group (20.7) (p<0.001). The time between injury and complete closure (12.5 versus 21.4 days) as well as duration of hospital stay (17.3 versus 23.8 days) was significantly less in the NPWT group (p<0.05). Conclusion: NPWT has a role in healing traumatic wounds and can be delivered effectively through hospital suction NPWT, which can also reduce the cost of therapy. We recommend its regular use in all patients presenting with post-traumatic, soft-tissue injuries when primary coverage is not possible.
Structured zinc oxide dressing for secondary intention wounds
Authors: Gao A.L. , Cole J.G. , Woolsey Z.T. , Stoecker W.V. 
Published: October 2017

Objective: Inexpensive methods for more rapid healing of secondary intention wounds are sought. This pilot study measured the wound healing rate for a new zinc oxide structured dressing technique. Method: In this study, we included the three patients with the largest wounds with onset during a one month period. A 3-ply gauze was cut and placed in the centre of each wound, leaving a 3-5mm rim of the wound exposed to the zinc gauze. The central gauze was soaked with 0.9% saline solution and the entire wound area was covered with 3 layers of Unna zinc oxide dressing. The central gauze size was modified to fit as the wound healed and the size changed. The wound was photographed at each visit and wound areas were obtained using best-fit ellipses. Results: The average wound closure rate is reported in the three wounds as 21.73mm2 per day. The scalp wound healed at a rate of 21.45mm2 per day.; the spider bite wound healed at a rate of 28.92mm2 per day; and the thigh wound healed at a rate of 14.81mm2 per day. Conclusion: Healing rates for the zinc gauze method exceed those previously reported for full-thickness wounds healing by secondary intention. Additional study of the new technique with more patients is needed before conclusions relevant to clinical practice can be made.

Abstract
The direct oral anticoagulant drugs (DOAC) are generally safe and effective in several clinical settings including acute venous thromboembolic disease, prophylaxis in the postoperative setting, prevention of thromboembolism in patients with non-valvular atrial fibrillation, and in the management of acute coronary syndrome. The relatively short half-life, rapid onset of action, and predictable pharmacokinetics should simplify periprocedural use of the DOAC. The aim of this work is to propose and summarize periprocedural management of patients treated with the DOAC in dental practice and to inform about the principal specifications of this treatment.
An interval observer design for uncertain nonlinear systems based on the T-S fuzzy model
Authors: Menasria Yamina , Bouras Hichem , Debbache Nasreddine 
Published: October 2017

AbstractA new approach to build an interval observer for nonlinear uncertain systems is presented in this paper. Nonlinear systems modeled in the Takagi-Sugeno (T-S) form are studied. A T-S proportional observer is first issued by pole-placement and LMI tools. Secondly, time-varying change of coordinates for each dynamic state estimation error is used to design an interval observer. The system state bounds are then directly deduced.
A new 3-D jerk chaotic system with two cubic nonlinearities and its adaptive backstepping control
Authors: Vaidyanathan Sundarapandian 
Published: October 2017

AbstractThis paper presents a new seven-term 3-D jerk chaotic system with two cubic nonlinearities. The phase portraits of the novel jerk chaotic system are displayed and the qualitative properties of the jerk system are described. The novel jerk chaotic system has a unique equilibrium at the origin, which is a saddle-focus and unstable. The Lyapunov exponents of the novel jerk chaotic system are obtained as L1= 0:2974, L2= 0 and L3= −3:8974. Since the sum of the Lyapunov exponents of the jerk chaotic system is negative, we conclude that the chaotic system is dissipative. The Kaplan-Yorke dimension of the new jerk chaotic system is found as DKY= 2:0763. Next, an adaptive backstepping controller is designed to globally stabilize the new jerk chaotic system with unknown parameters. Moreover, an adaptive backstepping controller is also designed to achieve global chaos synchronization of the identical jerk chaotic systems with unknown parameters. The backstepping control method is a recursive procedure that links the choice of a Lyapunov function with the design of a controller and guarantees global asymptotic stability of strict feedback systems. MATLAB simulations are shown to illustrate all the main results derived in this work.
Partial molecular volumes of cholesterol and phosphatidylcholine in mixed bilayers

Published: October 2017

Abstract
Dispersion of multilamellar liposomes of dimyristoylphosphatidylcholine (DMPC) and cholesterol (CHOL) were studied by vibrational densitometer for the CHOL mole fractions X = 0−0.54 in the temperature range 18−50 °C, both below and above the main phase transition. DMPC-CHOL bilayers served as a simple model for lipidic part of biological membrane. Volumetric parameters are essential not only to evaluate the data obtained by scattering and diffraction methods on model membranes but can provide valuable information about molecular packing in bilayers and the phase behaviour of lipid-CHOL mixtures. In this paper, preliminary results regarding the changes in the specific volume of lipid bilayer with increasing temperature and CHOL content are presented. Different values of apparent molecular volume of CHOL for different CHOL mole fraction pointed out the non-ideal mixing of DMPC and CHOL.
Inter- and intra-specific variability in δ13C and δ18O values of freshwater gastropod shells from Lake Lednica, western Poland

Published: October 2017

AbstractThis study focuses on the inter- and intra-specific variability in δ13C and δ18O values of shells and opercula of gastropods sampled live from the littoral zone of Lake Lednica, western Poland. The δ13C and δ18O values were measured in individual opercula of Bithynia tentaculata and in shells of Bithynia tentaculata, Gyraulus albus, Gyraulus crista, Lymnaea sp., Physa fontinalis, Radix auricularia, Theodoxus fluviatilis and Valvata cristata. The gastropods selected for the study are among the species most commonly found in European Quaternary lacustrine sediments. The carbon isotope composition of the gastropod shells was species-specific and the same order of species from the most to the least13C-depleted was observed at all sites sampled. Differences in shell δ13C values between species were similar at all sampling sites, thus the factors influencing shell isotopic composition were interpreted as species-specific. The δ18O values of shells were similar in all the species investigated. Significant intra-specific variability in shell δ13C and δ18O values was observed not only within the populations of Lake Lednica, which can be explained by heterogeneity of δ13C DIC, δ18O water and water temperature between the sites where macrophytes with snails attached were sampled, but also between individuals sampled from restricted areas of the lake’s bottom. The latter points to the importance of factors related to the ontogeny of individual gastropods.
Patient safety culture shapes presenteeism and absenteeism: a cross-sectional study among Croatian healthcare workers
Authors: Brborović Hana , Brborović Ognjen 
Published: October 2017

Abstract
Healthcare workers have high rates of injuries and illnesses at the workplace, and both their absence from work due to illness (absenteeism) or working ill (presenteeism) can compromise patient safety and the quality of health care delivered. Following this premise, we wanted to determine whether presenteeism and absenteeism were associated with patient safety culture (PSC) and in what way. Our sample consisted of 595 Croatian healthcare workers (150 physicians and 445 nurses) who answered the short-form WHO Health and Work Performance Questionnaire and the Hospital Survey on Patient Safety Culture. The results have confirmed the association with both presenteeism and absenteeism in several PSC dimensions, but not as we expected based on the premise from which we started. Opposite to our expectations, lower job performance (as a measure of presenteeism) was associated with higher PSC instead of lower PSC. Absenteeism, in turn, was associated with lower PSC, just as we expected. These findings suggest that it is the PSC that shapes presenteeist and absenteeist behaviour and not the other way around. High PSC leads to presenteeism, and low PSC to absenteeism. We also believe that the presenteeism questionnaires should be adjusted to health care and better define what lower performance means both quantitatively and qualitatively in a hospital setting
Vilém Gabler’s Library and Alexander the Great
Authors: Měřička Matěj 
Published: October 2017

Abstract
The article is divided into three parts. The first one aims to present the figure of Vilém Gabler, a close colleague of Karel Havlíček and František Ladislav Rieger, as a person important for the beginnings of Czech–French relations and for the spread of the knowledge of the Czech language and culture in the Czech milieu. The second part is devoted to the summary of previous research and the reconstruction of the personal library of Vilém Gabler, scattered in the central collection of the National Museum Library. The last, third part discusses Gabler’s article Alexander Veliký [Alexander the Great], written in reaction to the work Alexandre le Grand from the pen of Alphonse de Lamartine and under the impression of the events of 1859. Despite its thematic focus on the ancient commander, it provides abundant information on the author’s view of the recent Austrian-Czech past as well as present. It thus shows a man with his own world of opinion and moral schemes created based on his own experience from 1848 and strongly influenced by the study of French history, especially the period after 1789.
Logatome and Sentence Recognition Related to Acoustic Parameters of Enclosures
Authors: Kocinski Jedrzej , Ozimek Edward 
Published: October 2017

AbstractThe paper deals with relationship between speech recognition and objective parameters of enclosures. Six enclosures were chosen: a church, an assembly hall of a music school, two courtrooms of different volumes, a typical auditorium and a university concert hall. Dirac 4.1 software was used to record impulse responses (IRs) in the chosen measurement points of each enclosure. On this base, the following objective parameters of the enclosure were determined: Reverberation Time (RT), Early Decay Time (EDT), Weighted Clarity (C50) and Speech Transmission Index (STI). A convolution of the IRs with logatome tests and the Polish Sentence Test (PST) was made. Logatome recognition and speech reception threshold (SRT - i.e., SNR yielding 50% speech recognition) were evaluated and their dependence on the objective parameters were determined. Generally a linear relationship between logatome or SRT and RT or EDT was found. However, speech recognition was nonlinearly related (according to psychometric function) to STI values. The most sensitive range of the logatome and sentence recognition relative to STI changes corresponded to the middle range of STI values. Below and above this range, logatome and sentence recognition were much less dependent of STI changes.
Multifractal Nature of Diesel Engine Rattle Noise in Vehicle
Authors: Puchalski Andrzej , Komorska Iwona 
Published: October 2017

AbstractThe investigation results of the emission of noises accompanying the diesel engine powertrain running in unloaded condition at low or idle speed, are presented in the hereby paper. The multifractal nature of the tested signals was confirmed by means of two groups of parameters. The proposed local parameters are based on the distribution of the probability density of measures, segregated into subsets according to pointwise Holder exponents. The obtained spectra constitute a set of multifractal measures related to singularities representing the local scaling of measures in various points of the time series. Global parameters were defined on the basis of multifractal measures of the parametrised Renyi’s entropy. These are properties treating summarily the whole spectrum of the emitted noise and reflecting changes of the vibroacoustic energy levels generated by noise sources. The tests encompassing simultaneous application of both groups of parameters confirmed their efficiency in the comparative analysis as well as in the subjective assessment of the noise level generated in the drive system of vehicles with diesel engines. This opens new possibilities within the simulation range of vehicle noises, for the needs of constructing the passive and active reduction systems of the effects of the vibroacoustic energy propagation.
Utilisation of the Coherence Analysis in Acoustic Diagnostics of Internal Combustion Engines
Authors: Dabrowski Zbigniew , Dziurdz Jacek , Górnicka Dorota 
Published: October 2017

AbstractThe leading thought of the present text is that the internal combustion engine noise - regardless of all possible inconveniences - is a good information carrier that allows for the explicit diagnostics of such subtle defect as the valve face decrement which is so small that it is in practice ‘unnoticeable’ by the standard diagnostic-controlling system of a passenger car. However, such defect at its further propagation can be much more dangerous. Thus, diagnosing its initial state is worth trying. This study is a continuation of investigations where efforts were undertaken to perform the efficient diagnostics on the bases of observations and analyses of mechanical vibrations of the engine head.
Geographic envelope of the Moon and the identification of Moon landscapes with the use of the axiomatic method
Authors: Kyryliuk Serhii , Kholiavchuk Dariia 
Published: October 2017

Abstract
Three consequent concepts that build up the algorithm of the identification of modern landscapes on the Moon surface are suggested. They are anaglyphonosphere axiomatic and landscape concepts obtained with the use of the axiomatic method. The first concept depicts the geographic envelope of the Moon as an anaglyphonosphere layer (relief) that is a continuum (total environment). The latter becomes the research subject for both a geomorphologist and a landscape researcher. Continuity, dynamics, range (amplitude), and erosion potential determine anaglyphonosphere. Axiomatic concept means constructing the sole scheme (mathematically determined) of the search for the elementary surface units using the geometric interpretation of surface patterns of the Moon and its landscape interpretation. The landscape concept is based on the classical principles of the landscape theory and the axiomatic principles of the previous concept. The synthesis of concepts is implemented in the models of Moon landscapes of four scales: zero, linear, two- and three-dimensional. The paper offers the last two models of Davy Catena. Proposed concepts with appropriate correction can be used in parallel studies of the natural environment: geological, geomorphological, climatic, etc. The advantages of the axiomatic method consist in the objective approach to the division of the surface into specific units (the landscapes in our case). The proposed method of identifying and displaying the landscape complexes on the lunar surface can be a significant complement for the study and mapping of terrestrial planets, satellites of planet-giants, etc.

Abstract
This paper is devoted to the discovery of asteroids at the Molėtai Astronomical Observatory (MAO) in 2010- 2012 together with the orbital analysis of two dynamically interesting Near Earth Objects (NEOs) discovered at the MAO, namely 2006 SF77 and 2010 BT3. We used the OrbFit software v.5.0 to compute orbits and to analyze orbital evolution of 2006 SF77 and 2010 BT3. We computed value of the Lyapunov time: 830 years for 2006 SF77 and 1650 year for 2010 BT3.We also searched for possible impacts of 2006 SF77 and 2010 BT3 with the Earth, Venus and Mars in the next 15000 years.
Clutter and the Clash of Middle-class Tastes in the Domestic Interior
Authors: Ferry Kathryn Rachel 
Published: October 2017

Abstract
Interior design offered new members of the Victorian middle-class a means to demonstrate their success. Yet the choices they made in decorating domestic spaces could be harshly judged, in particular by self-proclaimed taste-makers who, though middle class themselves, came from a newly professionalised group of critics, artists and architects. The styles most hated by these arbiters were those designed to express wealth and status, often through new manufacturing techniques that promoted effect over craftsmanship. This article seeks to examine middle-class taste on its own terms and reveals how it evolved under the influence of the Aesthetic or “Art” Movement of the 1870s. Though ideas about what constituted “good” taste were more widely disseminated after this period the Victorian love of clutter continued unabated.
A dimensional restriction for a class of contact manifolds
Authors: Loiudice Eugenia 
Published: October 2017

Abstract
In this work we consider a class of contact manifolds (M, η) with an associated almost contact metric Structure (ϕ, ξ, η, g). This class contains, for example, nearly cosymplectic manifolds and the manifolds in the class C9 ⊕ C10 defined by Chinea and Gonzalez. All manifolds in the class considered turn out to have dimension 4n + 1. Under the assumption that the sectional curvature of the horizontal 2-planes is constant at one point, we obtain that these manifolds must have dimension 5.
Unveiling Hidden Social Design: New Roles for Sociologists
Authors: Popov Lubomir , David Gary 
Published: October 2017

Abstract
This paper will help foster a more favourable attitude to professional involvement in social design projects and highlight new areas of professional opportunity for sociologists. To overcome the psychological barriers to design engagement and to foster motivation for social design, the authors discuss a case of social design decision making by non-sociologists. The methodology is informed by Activity Theory and Design Theory, and the approach adopted is based on analyzing current best practices, departing from conventional and customary practices. The authors discuss the Fun Palace, which was an innovative architectural project in the 1960s Great Britain, conceived with a fundamental social aim of providing life-long education and professional retooling to working class people in a relaxed and entertaining environment. The paper highlights the sociological nature of decision making in the planning phase of the project as well as the need for sociological knowledge and skills. The explication of the social design activities in the Fun Palace project can inspire sociological practitioners with ideas about entering into various industries and, in particular, in the design of social organizations and buildings.
Spontaneous Spondylodiscitis - Epidemiology, Clinical Features, Diagnosis and Treatment
Authors: Petkova Aneta S. , Zhelyazkov Christo B. , Kitov Borislav D. 
Published: October 2017

AbstractSpontaneous spondylodiscitis is a rare but serious infectious disease which is a combination of an inflammatory process, involving one or more adjacent vertebral bodies (spondylitis), the intervertebral discs (discitis) and finally - the neighboring neural structures. In most cases the condition is due to a hematogenous infection and can affect all regions of the spinal cord, but it is usually localized in the lumbar area. The most common clinical symptom is a pronounced, constant and increasing nocturnal paravertebral pain, while consequently different degrees of residual neurological symptoms from nerve roots and/or spinal cord may appear. The disease course is chronic and the lack of specific symptoms often prolongs the time between its debut and the diagnosis. This delay in diagnosis determines its potentially high morbidity and mortality. Treatment is conservative in cases with no residual neurological symptoms and consists of antibiotic therapy and immobilization. Surgical treatment is necessary in patients with neurological deficit, spinal instability or drug resistance.
