Published: June 2017

Las ciudades inteligentes (smart cities) representan la evolución natural de la urbe tradicional gracias a la aplicación de las nuevas tecnologías de la información y de la comunicación a sus procesos de funcionamiento cotidiano. En la actualidad, se están implantando infraestructuras y dispositivos dirigidos a un amplio marco de acción de muy variada influencia en donde eficiencia energética, accesibilidad, movilidad, reducción de la contaminación o recursos sostenibles son los ítems más repetidos. En este proceso de transformación integral de la ciudad, los ciudadanos y los contenidos que van dirigidos a ellos deberían ser prioritarios, sin embargo parecen estar ausentes en la gran mayoría de estudios e investigaciones al respecto. Este trabajo centra su atención en el análisis de las aplicaciones digitales de las ciudades españolas de Valencia, A Coruña y Burgos, pioneras en el área de las smart cities y sus contenidos, así como en las innovaciones que mejoran su integración en el nuevo ecosistema digital.
Oldest fruit of Phyllanthaceae from the Deccan Intertrappean Beds of Singpur, Madhya Pradesh, India
Authors: Kapgate Dashrath , Manchester Steven R. , Stuppy Wolfgang 
Published: June 2017

AbstractA permineralized fruit from the latest Cretaceous of central India is recognized as a member of the malpighialean family Phyllanthaceae. The fruit is a tricarpellate, septicidal capsule 2.8 mm in diameter possessing two ellipsoidal seeds per locule. The pericarp includes two main layers, each uniseriate and composed mainly of columnar cells. This fruit, namedPhyllanthocarpon singpurensisgen. et sp. nov., confirms the presence of Phyllanthaceae in India ca 66 million years ago, well prior to its tectonic fusion with Eurasia, and is an early record for the euphorbioid clade in Malpighiales.
Comparison of Corrosion Resistance in Physiological Saline Solution of Two Austenitic Stainless Steels – 316LV and REX734
Authors: Romańczuk Eliza , Oksiuta Zbigniew 
Published: June 2017

Abstract
In this work two austenitic stainless steels, REX734 and 316LV were tested in terms of their microstructure and corrosion properties. The REX734 is a newer generation stainless steel, with modified chemical composition, in comparison to the 316LV grade. Potentiodynamic study of corrosion resistance was conducted in physiological saline solution (0.9% NaCl solution). In spite of the similarities of microstructure, grain size and phase structure in both materials, the corrosion tests revealed that the REX734, with lower nickel and higher nitrogen content, had better corrosion resistance than 316LV. Repassivation potential in the REX734 was almost six times higher than for the 316LV steel. Superior corrosion resistance of the REX734 steel was also confirmed by surface observations of both materials, since bigger and more densely distributed pits were detected in 316LV alloy.
Frictional Heating with Time-Dependent Specific Power of Friction
Authors: Topczewska Katarzyna 
Published: June 2017

Abstract
In this paper analytical solutions of the thermal problems of friction were received. The appropriate boundary-value problems of heat conduction were formulated and solved for a homogeneous semi–space (a brake disc) heated on its free surface by frictional heat fluxes with different and time-dependent intensities. Solutions were obtained in dimensionless form using Duhamel's theorem. Based on received solutions, evolution and spatial distribution of the dimensionless temperature were analyzed using numerical methods. The numerical results allowed to determine influence of the time distribution of friction power on the spatio-temporal temperature distribution in brake disc.
Application of Finite Element Method for Analysis of Nanostructures
Authors: Bocko Jozef , Lengvarský Pavol 
Published: June 2017

Abstract
The paper deals with application of the finite element method in modelling and simulation of nanostructures. The finite element model is based on beam elements with stiffness properties gained from the quantum mechanics and nonlinear spring elements with force-displacement relation are gained from Morse potential. Several basic mechanical properties of structures are computed by homogenization of nanostructure, e.g. Young's modulus, Poisson's ratio. The problems connecting with geometrical parameters of nanostructures are considered and their influences to resulting homogenized quantities are mentioned.

Published: June 2017

Abstract
A tool with a punch of ø5 mm and a die with a specially formed circular cavity and an annular gap was used for mechanical joining of thin hot-dip galvanized steel sheets. The active parts of punch and die were covered by PVD coating of ZrN type with LARC technology. The punches and the dies were tested in a complex tool by joining thin hot-dip galvanized steel sheets with the pressing force of 7,000 N. Decohesion of coating with width of 100 – 200 μm was observed in the perimeter of cylindrical part of ø5×4 mm in the in edge of punch radius R = 0.5 mm with deposited ZrN coating after the creation of 150 mechanical joints. The decohesion of PVD coating occurred mainly in the surroundings of the radius R = 0.5 mm on the front plane of ø15 mm part.
Bandwidth Assessment for MultiRotor UAVs
Authors: Ferrarese Gastone 
Published: June 2017

AbstractThis paper is a technical note about the theoretical evaluation of the bandwidth of multirotor helicopters. Starting from a mathematical linear model of the dynamics of a multirotor aircraft, the transfer functions of the state variables that deeply affect the stability characteristics of the aircraft are obtained. From these transfer functions, the frequency response analysis of the system is effected. After this analysis, the bandwidth of the system is defined. This result is immediately utilized for the design of discrete PID controllers for hovering flight stabilization. Numeric simulations are shown to demonstrate that the knowledge of the bandwidth is a valid aid in the design of flight control systems of these machines.
Research advances in reactivation of hepatitis virus after chemotherapy for non-Hodgkin’s lymphoma-combined hepatitis B virus infection
Authors: Ma Shujun 
Published: June 2017

AbstractInfection rate of hepatitis B virus (HBV) in our country remains high. Many patients showed combined HBV infection; the most common blood system disease is non-Hodgkin’s lymphoma (NHL)-combined HBV infection. Drugs used in treating lymphoma may induce different degrees of HBV reactivation. Such condition may lead to hepatic failure or death. Currently, scholars pay increasing attention to reactivation of HBV by rituximab and/or chemotherapy for NHL-combined HBV patients. This study summarizes research advances in this topic, with a view of providing background information for further research.
Review of Research on Immunotherapy of Severe Surgical Infection
Authors: Liang Quan 
Published: June 2017

Abstract
Severe surgical infection refers to infection after surgical treatment or surgical operation, accounting for approximately 30% of surgical diseases. This type of infection can cause extensive inflammation and tissue injury and reduce success rate of surgical treatments. Immune defense plays an important role in antiinfection treatment of hosts. Infection immunity is a series of physiological defense mechanisms for recognition of immune system and removal of pathogens. As for severe surgical infection, immunotherapy becomes an important and promising therapy for severe surgical infection. This study summarizes recent progresses achieved in immunization and immunotherapy of surgical infection.
Research Progress on Effects of Regulatory B Cells in Infection Immunity
Authors: Miao Ting 
Published: June 2017

Abstract
B cells play immunomodulatory roles mainly by presenting antigens and producing antibodies. In recent years, some B cells were shown to exhibit regulatory functions. This type of B cell was named regulatory B cells (Bregs). Bregs can mediate immune tolerance to inhibit excessive inflammatory responses and to accelerate recovery of inflammation by producing interleukin 10 and/or transforming growth factor β1 and other inhibitory cytokines. Studies showed that Bregs play important roles in parasites, bacteria, and viral infections. This study reviews biological characteristics, functions, and microsignal regulation of Bregs and their mechanism in infectious diseases and related research progress.
Re-shaping King Lear: Space, Place, Costume, and Genre
Authors: Hattaway Michael 
Published: June 2017

Abstract
Performance studies must enjoy parity of esteem with critical studies because they remind us of the plurality of “readings” that are generated by a Shakespearean text. Shakespeare seems to have apprehended this when, in Othello, he used a nonce-word, “denotement”, which applies to Othello’s reading of his wife in his mind’s eye. I examine other sequences in which we watch a character “reading” on-stage or imagined action, in Hamlet, Titus Andronicus, Cymbeline, Richard II, and Troilus and Cressida. In Hamlet this involves re-reading as well as generic displacement, which, I argue, is a way of rendering inwardness. As I test case, I analyse a production of King Lear by Shakespeare’s Globe, on a fairground stage, in which the king reshaped himself, became a folkloric figure, like a figure in Nashe’s Summer’s Last Will and Testament. The play itself was thus, indecorously, reshaped as “The Tale of King Lear”. “Dramatic truth”, therefore, in no way depends upon theatrical “realism”.
Re-reading Shakespeare’s Richard III: Tragic Hero and Villain?
Authors: Keenan Siobhan 
Published: June 2017

Abstract
The discovery of the body of the historical Richard III under a Leicester car park in 2012 sparked fresh interest in one of England’s most controversial kings. Accused of murdering his nephews—the Princes in the Tower—Richard’s reign was cut short when he was defeated by Henry Tudor, Earl of Richmond (later Henry VII), at the Battle of Bosworth (1485). Richard was subsequently demonised in Tudor historiography, perhaps most famously by Sir Thomas More in his “History of King Richard the thirde” (printed 1557). It is to More that we owe the popular image of Richard III as a “croke backed” and “malicious” villain (More 37), an image which Shakespeare has been accused of further codifying and popularising in his Richard III. Today, the historical Richard III’s defenders argue for the king’s good qualities and achievements and blame early writers such as More and Shakespeare for demonising Richard; but, in Shakespeare’s case at least, this essay argues that the possibility of a sympathetic—and even a heroic—reading of the king is built in to his characterisation of Richard III.
The Eye and Refractive Geography in Pericles
Authors: Matei-Chesnoiu Monica 
Published: June 2017

AbstractThe paper highlights the cultural constructedness of vision in the early modern period by drawing on heteroglossic representations of the eye in early English texts, ranging from anatomy and physiology treatises to philosophy, poetry, emblems, and geometrical perspective in astronomy and land surveying. The argument is based on the association of word and image in early modern representations of space, mirrored in Ortelius’s notion of geography as the eye of history, which shows the importance of the visual element in the system of acquisition and transmission of knowledge in the Renaissance. In the particular case ofPericles, the play unfolds over a vast international geography and creates powerful visual effects. The imaginative spatial conventions of the play can be assimilated to the system of geometrical projection on which maps depended. Locations are used according to a geometric triangulation system to refract the imaginative and spatial vision. As in emblems, the locations unfolding in the play give the action meaning in the process of involved spectatorship. Moreover, in the theatre, the lone monocular beholder of mathematical linear perspective is multiplied into a choric array of spectators.
Numerical Analysis of a Small-Size Vertical-Axis Wind Turbine Performance and Averaged Flow Parameters Around the Rotor
Authors: Rogowski Krzysztof , Maroński Ryszard , Piechna Janusz 
Published: June 2017

AbstractSmall-scale vertical-axis wind turbines can be used as a source of electricity in rural and urban environments. According to the authors’ knowledge, there are no validated simplified aerodynamic models of these wind turbines, therefore the use of more advanced techniques, such as for example the computational methods for fluid dynamics is justified. The paper contains performance analysis of the small-scale vertical-axis wind turbine with a large solidity. The averaged velocity field and the averaged static pressure distribution around the rotor have been also analyzed. All numerical results presented in this paper are obtained using the SST k-ω turbulence model. Computed power coeffcients are in good agreement with the experimental results. A small change in the tip speed ratio significantly affects the velocity field. Obtained velocity fields can be further used as a base for simplified aerodynamic methods.

The Application of Vibration Accelerations in the Assessment of Average Friction Coefficient of a Railway Brake Disc
Authors: Sawczuk Wojciech 
Published: June 2017

Abstract
Due to their wide range of friction characteristics resulting from the application of different friction materials and good heat dissipation conditions, railway disc brakes have long replaced block brakes in many rail vehicles. A block brake still remains in use, however, in low speed cargo trains. The paper presents the assessment of the braking process through the analysis of vibrations generated by the components of the brake system during braking. It presents a possibility of a wider application of vibroacoustic diagnostics (VA), which aside from the assessment of technical conditions (wear of brake pads) also enables the determination of the changes of the average friction coefficient as a function of the braking onset speed. Vibration signals of XYZ were measured and analyzed. The analysis of the results has shown that there is a relation between the values of the point measures and the wear of the brake pads.

Published: June 2017

Abstract
Magnetic Resonance Super-resolution Imaging Measurement (MRIM) is an effective way of measuring materials. MRIM has wide applications in physics, chemistry, biology, geology, medical and material science, especially in medical diagnosis. It is feasible to improve the resolution of MR imaging through increasing radiation intensity, but the high radiation intensity and the longtime of magnetic field harm the human body. Thus, in the practical applications the resolution of hardware imaging reaches the limitation of resolution. Software-based super-resolution technology is effective to improve the resolution of image. This work proposes a framework of dictionary-optimized sparse learning based MR super-resolution method. The framework is to solve the problem of sample selection for dictionary learning of sparse reconstruction. The textural complexity-based image quality representation is proposed to choose the optimal samples for dictionary learning. Comprehensive experiments show that the dictionary-optimized sparse learning improves the performance of sparse representation.

Published: June 2017

Abstract
Simple, efficient, clean, and stereospecific protocols of protection of phosphorus atom with borane and deprotection from the borane complexes of the tertiary phosphines in mild conditions are reported. The proposed protection/deprotection reactions tolerate a range of functional groups and lead to pure products with excellent yield with no need for application of chromatographic or crystallisation purification procedures. For the first time mechanisms of the reactions of phosphine protection and deprotection have been studied based on experimental kinetic data as well as quantumchemical calculations, which allows designing reaction conditions suitable for a given substrate.

Abstract
Botosani Municipality faces since 2008 to massive trees drying, in areas such as Mihai Eminescu Boulevard, Calea Nationala Street, Marchian Street. In many cases, although the trees have been toileted, treated with substances used for pest control, there couldn’t be saved but very few specimens, but most of them have been cut down. Furthermore, on Mihai Eminescu Boulevard, there no longer leaf out for a few years the chestnut trees, sycamore trees, linden trees, cherry trees, acacia, maple trees, which probably will be cut down eventually.
The incidence of burnout in nursing practice
Authors: Ondriová Iveta 
Published: June 2017

Abstract

Introduction. The burnout syndrome is significantly associated with nursing profession. Individuals suffering from the syndrome manifest important health problems. More information about prevalence and risk factors for burnout is needed to prevent the syndrome and to determine the most appropriate clinical interventions when the disorder appears.

Aim. The aim of the submitted thesis is to map existence of burnout syndrome in the nurse profession, to compare its existence according to the type department and to find out impact of the demographic characteristics on the burnout syndrome origin.

Material and methods. In the empirical part we describe work method, data analyses, their processing and statistical testing. To collect information we used standardized questionnaire, Burnout Measure (BM) – burnout questionnaire. Acquired data are interpreted in charts.

Results. Result of our research is to find out that existence of burnout syndrome in profession of nurse is considerable, while we do not observe significant differences between different types of workplace. We have identified by statistical processing the impact of demographic index on the occurrence of burnout syndrome. As statistically important we consider in light of burnout syndrome occurrence characteristic, age and duration of practice. Result of our research is to find out that existence of burnout syndrome in profession is considerable, while we do not observe significant differences between different types of workplace.

Conclusions. Based on our results we recognize that it is necessary to strengthen the burnout syndrome prevention among nurses. The occurrence of burnout syndrome was confirmed in our study. The average value of BM indices in our sample was 3.40 for all nurses, a BM index of 3.44 for nurses in sample A and a BM index of 3.36 for nurses in group B. These average values of burnout clearly show that their averages are in the range of “presence of signals of burnout” In this category of the BM index there are significant signs of burnout, but it is not developed burnout syndrome. One alarming finding was that three nurses in sample B found themselves in BM index band 5, which means an emergency state in which it is necessary to seek professional help.
