Medical English Genres - Indispensable Tool for Effective Academic and Professional Communication / Žanrovi u engleskom jeziku za potrebe medicine: neophodno sredstvo za efikasnu akademsku i profesionalnu komunikaciju
Authors: Milosavljević Nataša , Antić Zorica 
Published: May 2015

Summary
The English language is undoubtedly lingua franca of contemporary globalised world. Besides its widespread use in official communication among different countries, it has also huge impact within the borders of one country as well. Taking into account the fact that nowadays it represents the basic communicative tool in the field of medical science it has acquired both scientific and educational value. The concept of genre is a key term in medical communication and includes the written and spoken genres. International use of English in the field of medical science encompasses not only sheer transfer of new information and ideas but adoption of the well established features of written and spoken genres. However, it should be emphasized that these genres are at the same time dynamic and subject to changes in wider contexts surrounding this discipline.

Abstract
The stratigraphical distribution of Porosphaera globularis, a common calcareous sponge in the Upper Cretaceous (mostly Campanian and Maastrichtian) of Poland was studied. The presented material, both new and from museum collections, comes from the Campanian of the Miechow Synclinorium, in southern Poland, and from the Lower Campanian of Mielnik in the south-eastern part of the Mazury-Podlasie Homocline, in eastern Poland. The significance of the species in extra-regional correlation, its palaeobiogeography and stratigraphical potential is critically reviewed.
The Effect Of Saline Mine Waters Discharge From Hard Coal Mine On The Ecological State Of The Vistula River
Authors: POLICHT-LATAWIEC Agnieszka 
Published: May 2015

Abstract
The aim of the study was to determine the influence of coal mine waters on water quality in the Vistula River. Water samples for laboratory analysis were collected in 2011 and 2012 on one kilometer long section of the river. Basic parameters were measured at the collection spot. The study asseses the dynamics of physicochemical water properties, fulfillment of the quality requirements necessary to introduce contaminated water into the river, water salinity, quality, and utility values. The study indicates that water quality of the Vistula River has been rapidly decreasing as a result of coal mine water introduction. Water becomes degraded, unfavourable for fish communities and unsuitable for use by people. Coal mine water contamination exceeds allowable pollution levels stated by legal regulations. Self-purification of the river is efficient as contamination levels decrease at the length of the examined section of the river.
Land Use Dataset Collection And Publication Based On Lucas And Hilucs
Authors: KLIMENT Marcel , KOČICA Jakub , KLIMENT Tomáš 
Published: May 2015

Abstract
Spatial data have become very important phenomena within the last decade in Europe due to a strong support from the political spectrum with regard to related legislation and resulting in financial support to several research, educational, and enlargement projects. INSPIRE (Infrastructure for Spatial Information in the European Community) Directive indeed defines the principles for the harmonization of spatial data infrastructure in the European community, including Land Use and Land Cover data themes. INSPIRE defines a methodology on how to transform datasets to common data models, but it does not cover the process of data collection and update, because it is out of its scope. Evaluation of the Land Use dataset derived from remote sensing products complemented by fieldworks has been realized since 2006 by Eurostat within the LUCAS (Land Use and Cover Area frame Survey) project. The work presented in this paper follows the LUCAS fieldwork methodology, which was applied during the fieldwork in July 2014 in the City of Zagreb (Croatia), to use at the local (municipal) geoportal level. The surveying groups collected point features with the following data type attributes: Land Use codes defined by HILUCS (Hierarchical INSPIRE Land Use Classification System) and optional Land Cover codes defined by LUCAS classification. In addition, photographs representing the observed areas were collected by cameras embedded in the mobile GIS platforms. An update of original topological layer was performed and Web GIS components for sharing the newly developed datasets were implemented. The results presented provide a suitable proposal for fieldworks methodology and updates of a land use database in line with the INSPIRE directive applicable at a local spatial data infrastructure level.
Healthy occupational culture for a worker-friendly workplace / Kultura zdravih organizacija – radna mjesta prijatelji radnika
Authors: Grabovac Igor , Mustajbegović Jadranka 
Published: May 2015

Abstract
Work has numerous health and wellbeing benefits, but it also involves physical hazards and psychological exertion. Today the scale has tipped toward psychosocial factors. Workers’ mental health affects their intellectual, emotional, and social growth, as well as work ability, productivity, and ultimately organisational productivity and competitiveness on the market. Even though companies may have an internal hierarchy that lowers stress at work, there are other formal and informal social processes that can affect (positively or negatively) the cohesion within the work unit. Safety culture of an organisation is a product of individual and group values, opinions, competences, and behavioural patterns that determine how occupational health and safety are implemented. Organisations that nurture positive safety culture understand the importance of health and safety and believe in prevention rather than dealing with consequences. Jobs that are stable, autonomous, and reasonably physically and psychologically demanding are far more likely to lower work-related stress and boost worker satisfaction. In fact, employee empowerment is one of the best ways to achieve good psychosocial health at the workplace.

Authors: Boncheva M. , Turnovska T. 
Published: May 2015

Summary
Since time immemorial the fruits of aronia melanocarpa (rich of bioflavonoides) have been known for their medicinal properties. Present-day research of the pharmacological effects of aronia melanocarpa juice and fruits intake indicates that their high contents of anthocyanins is closely related to the health enhancing properties of this plant. This is a key fact which can be used in the prevention of most commonly spread, socially significant diseases, reducing for instance the total risk of cardio-vascular diseases. The great molecular variety anthocyanins possess and the role they play in cell metabolism, are still being investigated. This gives grounds to study the effects of Aronia melanocarpa on human cells, tissues, and organs. The aim of this study is to trace the effect of 150-200 ml aronia melanokarpa juice daily oral intake on the adipocyte hormones leptin (Lp), resistine (Rs) and adiponectin (Adn) blood levels in 10 patients with high body mass index (BMI, kg/m2) and high waist circumference. We used ELISA methods for hormonal analyses. During the study-period of two months patients did not change anything in their lifestyle. In the study group, the levels of Rs, Lp and Adn changed significantly compared to their baseline levels (averages, ng/mL) - 6.93 ± 0.137, 18.40 ±1.021 and 7.98 ± 0.077 vs. 5.06 ± 0.011, 15.23 ± 0.906 and 10.45 ± 0.103 at the end of the second month, respectively. Compared with the control group of 6 people, matched for BMI, not receiving aronia melanocarpa juice, these values were markedly different. Patients taking aronia melanokarpa juice report improvement in various conditions that have caused them discomfort before the research started: pain in the muscles and joints faded away and were replaced by a new feeling of strength, headache attacks disappeared, improvement in memory and sleep were reported, regular defecation, no signs of gastric discomfort, better vision, a quicker auditory reaction, motivation for having sex, good mood were also reported. Obese patients with insulin resistance have decreased serum adiponectin and increased serum resistin and leptin. The levels of these three hormones changed positively after chronic intake of aronia juice. We recommend a daily intake of aronia juice for the prevention of health.

Summary
The laser coagulation at the apical part of the root canal after vital extirpation is a proper method of preventing complications such as pain, bleeding, remaining vital pulp. The aim of the present survey is to register the thermal changes that occur on the tooth surfaces during laser treatment of the root canal after vital extirpation. An in vitro study of 30 extracted teeth has been conducted. The teeth have been prepared with ProTaper nickel-titanium machine tools and wiped dry. During the course of laser treatment of root canals with a diode laser DenLase temperatures, changes of the surface of the hard dental tissues have been recorded with infrared camera FLIR T330. The captured thermal images have been processed with software product Flir Reporter Pro 9. In conclusion, temperature changes in hard dental tissues at diode laser treatment of the root canal are biocompatible.
Model–Based Techniques for Virtual Sensing of Longitudinal Flight Parameters
Authors: Seren Cédric , Ezerzere Pierre , Hardier Georges 
Published: May 2015

Abstract
Introduction of fly-by-wire and increasing levels of automation significantly improve the safety of civil aircraft, and result in advanced capabilities for detecting, protecting and optimizing A/C guidance and control. However, this higher complexity requires the availability of some key flight parameters to be extended. Hence, the monitoring and consolidation of those signals is a significant issue, usually achieved via many functionally redundant sensors to extend the way those parameters are measured. This solution penalizes the overall system performance in terms of weight, maintenance, and so on. Other alternatives rely on signal processing or model-based techniques that make a global use of all or part of the sensor data available, supplemented by a model-based simulation of the flight mechanics. That processing achieves real-time estimates of the critical parameters and yields dissimilar signals. Filtered and consolidated information is delivered in unfaulty conditions by estimating an extended state vector, including wind components, and can replace failed signals in degraded conditions. Accordingly, this paper describes two model-based approaches allowing the longitudinal flight parameters of a civil A/C to be estimated on-line. Results are displayed to evaluate the performances in different simulated and real flight conditions, including realistic external disturbances and modeling errors.
A Safe Supervisory Flight Control Scheme in the Presence of Constraints and Anomalies
Authors: Franzè Giuseppe , Furfaro Angelo , Mattei Massimiliano , Scordamaglia Valerio 
Published: May 2015

Abstract
In this paper the hybrid supervisory control architecture developed by Famularo et al. (2011) for constrained control systems is adopted with the aim to improve safety in aircraft operations when critical events like command saturations or unpredicted anomalies occur. The capabilities of a low-computational demanding predictive scheme for the supervision of non-linear dynamical systems subject to sudden switchings amongst operating conditions and time-varying constraints are exploited in the flight control systems framework. The strategy is based on command governor ideas and is tailored to jointly take into account time-varying set-points/constraints. Unpredictable anomalies in the nominal plant behaviour, whose models fall in the category of time-varying constraints, can also be tolerated by the control scheme. In order to show the effectiveness of the proposed approach, simulations both on a high altitude performance demonstrator unmanned aircraft with redundant control surfaces and the P92 general aviation aircraft are discussed.
Detection and Identification of Loss of Efficiency Faults of Flight Actuators
Authors: Ossmann Daniel , Varga Andreas 
Published: May 2015

Abstract
We propose linear parameter-varying (LPV) model-based approaches to the synthesis of robust fault detection and diagnosis (FDD) systems for loss of efficiency (LOE) faults of flight actuators. The proposed methods are applicable to several types of parametric (or multiplicative) LOE faults such as actuator disconnection, surface damage, actuator power loss or stall loads. For the detection of these parametric faults, advanced LPV-model detection techniques are proposed, which implicitly provide fault identification information. Fast detection of intermittent stall loads (seen as nuisances, rather than faults) is important in enhancing the performance of various fault detection schemes dealing with large input signals. For this case, a dedicated fast identification algorithm is devised. The developed FDD systems are tested on a nonlinear actuator model which is implemented in a full nonlinear aircraft simulation model. This enables the validation of the FDD system’s detection and identification characteristics under realistic conditions.
A Hamiltonian Approach to Fault Isolation in a Planar Vertical Take–Off and Landing Aircraft Model
Authors: Rodriguez-Alfaro Luis H. , Alcorta-Garcia Efrain , Lara David , Romero Gerardo 
Published: May 2015

Abstract
The problem of fault detection and isolation in a class of nonlinear systems having a Hamiltonian representation is considered. In particular, a model of a planar vertical take-off and landing aircraft with sensor and actuator faults is studied. A Hamiltonian representation is derived from an Euler-Lagrange representation of the system model considered. In this form, nonlinear decoupling is applied in order to obtain subsystems with (as much as possible) specific fault sensitivity properties. The resulting decoupled subsystem is represented as a Hamiltonian system and observer-based residual generators are designed. The results are presented through simulations to show the effectiveness of the proposed approach.
A Fault Tolerant Direct Control Allocation Scheme with Integral Sliding Modes
Authors: Hamayun Mirza Tariq , Edwards Christopher , Alwi Halim , Bajodah Abdulrahman 
Published: May 2015

Abstract
In this paper, integral sliding mode control ideas are combined with direct control allocation in order to create a fault tolerant control scheme. Traditional integral sliding mode control can directly handle actuator faults; however, it cannot do so with actuator failures. Therefore, a mechanism needs to be adopted to distribute the control effort amongst the remaining functioning actuators in cases of faults or failures, so that an acceptable level of closed-loop performance can be retained. This paper considers the possibility of introducing fault tolerance even if fault or failure information is not provided to the control strategy. To demonstrate the efficacy of the proposed scheme, a high fidelity nonlinear model of a large civil aircraft is considered in the simulations in the presence of wind, gusts and sensor noise.
Clinical evaluation of periodontal health during orthodontic treatment with fixed appliances
Authors: Hănțoiu T. , Monea Adriana , Lazăr Luminița , Hănțoiu Liana 
Published: May 2015

Abstract
Objectives: Fixed orthodontic appliances make daily application of oral hygiene standard procedures more difficult and in time may lead to accumulation of oral biofilms and development of gingivitis and hyperplasia. The aim of the study is to evaluate the periodontal health expressed by clinical indices in patients under orthodontic treatment with fixed appliances, according to different oral hygene maintenance programs. Material and method: We performed a randomized prospective study on 60 patients with fixed orthodontic appliances (17-25 years of age) devided in three study groups. The clnical indices recorded were: modified gingival index, plaque index and sulcular bleeding index. Statistical analysis or the results were carried out using Student t test. Results: The patients were randomly divided into three groups: group A-patients were instructed to use electric brush, water flosser and interdental brush, group B- electric brush, interdental brush and fluoride and group C- manual brushing and fluoride. Statistical comparison of the values of the indexes with the Student t test for independent samples showed statistically significant differences in all three groups of patients studied between initial and final values of all recorded clinical parameters. Conclusions: Fixed orthodontics do not induce periodontal disease if basic principles of oral hygiene are followed in compliant patients, which are correctly instructed to deal with real challenge, represented by complete elimination of debris and bacterial accumulation.
Limitations when use chloramphenicol-bcyclodextrins complexes in ophtalmic solutions buffered with boric acid/borax system
Authors: Todoran Nicoleta , Ciurba Adriana , Rédai Emőke , Ion V. , Lazăr Luminița , Sipos Emese 
Published: May 2015

Abstract
Chloramphenicol eye drops are commonly prescribed in concentrations of 0.5-1% in the treatment of infectious conjunctivitis. In terms of ophthalmic solution preparation, the major disadvantage of chloramphenicol consists in its low solubility in water. The solubility is increased by substances that form chloramphenicol-complexes, for example: boric acid/borax or cyclodextrins. Objective: Experimental studies aimed to evaluate the potential advantages of enhancing the solubility and stability of chloramphenicol (API) by molecular encapsulation in b-cyclodextrin (CD), in formulation of ophthalmic solutions buffered with boric acid/borax system. Methods and Results: We prepared four APIb- CD complexes, using two methods (kneading and co-precipitation) and two molar ratio of API/b-cyclodextrin (1:1 and 1:2). The formation of complexes was proved by differential scanning calorimetry (DSC) and the in vitro dissolution tests. Using these compounds, we prepared eight ophthalmic solutions, formulated in two variants of chloramphenicol concentrations (0.4% and 0.5%). Each solution was analyzed, by the official methods, at preparation and periodically during three months of storing in different temperature conditions (4°C, 20°C and 30°C). Conclusions: Inclusion of chloramphenicol in b-cyclodextrin only partially solves the difficulties due to the low solubility of chloramphenicol. The protection of chloramphenicol molecules is not completely ensured when the ophthalmic solutions are buffered with the boric acid/borax system.

Δn/mmu = λh(x)|u|q-1u + u|u|pe|u|β in Ω, u = ∇u = ⋯ = ∇m-1u = 0 on ∂Ω,
where Ω ⊂ ℝn, n ≥ 2m ≥ 2, is a bounded domain

0 < q < n/(m-1) < p+1,
β ∈ (1,n/(n-m)] and
λ > 0. Using the Nehari manifold and fibering maps, we show the
existence and multiplicity of solutions.

Authors: Agarwal Ravi P. , Çetin Erbil 
Published: May 2015

Abstract
We consider the following third order three-point boundary value problem on a half-line:
x'''(t)+q(t)f(t,x(t),x'(t),x''(t)) = 0, t ∈ (0,+∞),
x'(0) = A, x(η) = B, x''(+∞) = C,
where η ∈ (0,+∞), but fixed, and
f : [0,+∞) × ℝ3 → ℝ satisfies Nagumo's condition. We apply Schauder's fixed point theorem, the upper and lower solution method, and topological degree theory, to establish existence theory for at least one unbounded solution, and at least three unbounded solutions. To demonstrate the usefulness of our results, we illustrate two examples.
Rers2014 and Mrs2014: New High-Precision Rigid Earth Rotation and Moon Rotation Series
Authors: Pashkevich V.V. 
Published: May 2015

Abstract
Numerical investigation of the Earth and Moon rotational motion dynamics is carried out at a long time intervals. In our previous studies (Pashkevich, 2013), (Pashkevich and Eroshkin, 2011) the high-precision Rigid Earth Rotation Series (designated RERS2013) and Moon Rotation Series (designated MRS2011) were constructed. RERS2013 are dynamically adequate to the JPL DE422/LE422 (Folkner, 2011) ephemeris over 2000 and 6000 years and include about 4113 periodical terms (without attempt to estimate new subdiurnal and diurnal periodical terms). MRS2011 are dynamically adequate to the JPL DE406/LE406 (Standish, 1998) ephemeris over 418, 2000 and 6000 years and include about 1520 periodical terms. In present research have been improved the Rigid Earth Rotation Series RERS2013 and Moon Rotation Series MRS2011, and as a result have been constructed the new high-precision Rigid Earth Rotation Series RERS2014 and Moon Rotation Series MRS2014 dynamically adequate to the JPL DE422/LE422 ephemeris over 2000 and 6000 years, respectively. The elaboration of RERS2013 is carried out by means recalculation of sub-diurnal and diurnal periodical terms. The residuals in Euler angles between the numerical solution and RERS2014 do not surpass 3 ìas over 2000 years. Improve the accuracy of the series MRS2011 is obtained by using the JPL DE422/LE422 ephemeris. The residuals in the perturbing terms of the physical librations between the numerical solution and MRS2014 do not surpass 8 arc seconds over 6000 years
Zen, Erfahrung und Philosophie: Ueda Shizuteru und die Schöpfung einer Zen-Philosophie
Authors: Kopf Gereon 
Published: May 2015

Abstract
The philosophers of the so-called Kyoto school famously synthesized Zen Buddhist thought and the academic philosophy of 19th and early 20th century Europe in their work. Shizuteru Ueda, one of disciples of Nishitani, developed a model to categorize three different types of Zen discourse. However, in the English language literature “Zen” is frequently essentialized as “mystical” and as at odds with the philosophical project. Such a misconception not only does injustice to the diverse and vibrant traditions of Zen Buddhism, it also belittles the contributions many of their members have made to the philosophical discourse in general. This essay will introduce Ueda’s model to present one of way of imagining “Zen philosophy” and to investigate how the project of philosophy in general can be understood from within the Japanese Zen Buddhist tradition. It will argue that since philosophy is not a matter of ideology but one of method, “doing philosophy within the Zen tradition” requires a translation of the Zen idiom. It will further demonstrate how Ueda identifies sources for and methods of philosophy within the Zen Buddhist traditions. The goal of this essay is to better understand the philosophical projects of one member of the Kyoto school, on the one side, and to envision a notion of “philosophy” that is relevant for the age of globalism and multiculturalism, on the other.
