Symmetry analysis for hyperbolic equilibria using a TB/dengue fever model
Authors: Massoukou R. Y. M’pika , Govinder K. S.
Published: August 2016

We investigate the interplay between Lie symmetry analysis and dynamical systems analysis. As an example, we take a toy model describing the spread of TB and dengue fever. We first undertake a comprehensive dynamical systems analysis including a discussion about local stability. For those regions in which such analyzes cannot be translated to global behavior, we undertake a Lie symmetry analysis. It is shown that the Lie analysis can be useful in providing information for systems where the (local) dynamical systems analysis breaks down.

Published: August 2016

Composite materials, with characteristics of light weight and high strength, are useful in manufacturing. Therefore, precise design and analysis is the first key procedure in composite applications, improper analysis or use of composite materials may cause serious failures. In this paper, wavelet finite element method (WFEM) based on B-spline wavelet on the interval (BSWI) is constructed for precise analysis of laminated plates and shells, which gives a guidance in design and application of composite structures. First, FEM formulations are derived from the generalized potential energy function based on the generalized variational principle and virtual work principle. Then, BSWI scaling functions are used as interpolation function to discretize the solving displacement field variables. At the same time, transformation matrix is constructed and used to translate the meaningless wavelet coefficients into physical space. At last, the static analysis results can be obtained by solving the FEM formulations. Due to the excellent features of BSWI, such as multiresolution, multiscale, localization and excellent numerical approximation characteristics etc., BSWI-based FEM can achieve accurate and efficient analysis by comparing with traditional methods. In the end, the effectiveness of the constructed BSWI WFEM is verified through several numerical examples.

We also show the corresponding results in zig-zag product of Schreier graphs [Formula: see text] with a [Formula: see text]-cycle.
On ∗-clean group rings over abelian groups
Authors: Han Dongchun , Ren Yuan , Zhang Hanbin
Published: August 2016

An associative ring with unity is called clean if each of its elements is the sum of an idempotent and a unit. A clean ring with involution ∗ is called ∗-clean if each of its elements is the sum of a unit and a projection (∗-invariant idempotent). In a recent paper, Huang, Li and Yuan provided a complete characterization that when a group ring [Formula: see text] is ∗-clean, where [Formula: see text] is a finite field and [Formula: see text] is a cyclic group of an odd prime power order [Formula: see text]. They also provided a necessary condition and a few sufficient conditions for [Formula: see text] to be ∗-clean, where [Formula: see text] is a cyclic group of order [Formula: see text]. In this paper, we extend the above result of Huang, Li and Yuan from [Formula: see text] to [Formula: see text] and provide a characterization of ∗-clean group rings [Formula: see text], where [Formula: see text] is a finite abelian group and [Formula: see text] is a field with characteristic not dividing the exponent of [Formula: see text].
More Precise Decision-Making Methodology in the Temporalized Body of Evidence. Application in the Information Technology Management
Authors: Sirbiladze Gia , Khutsishvili Irina , Badagadze Otar , Kapanadze Mikheil
Published: August 2016

In this paper, we perform the analysis of temporalized structure of a body of evidence and possibilistic Extremal Fuzzy Dynamic System (EFDS) for the construction of more precise decisions based on the expert knowledge stream. The process of decision precision consists of two stages. In the first stage the relation of information precision is defined on a monotone sequence of bodies of evidence. The principle of negative imprecision is developed, as the maximum principle of knowledge ignorance measure of a body of evidence. Corresponding mathematical programming problem is constructed. On the output of the first stage we receive the expert knowledge precision stream of the criteria with respect to any decision. In the second stage the constructed stream is an input trajectory for the finite possibilistic model of EFDS. A genetic algorithm approach is developed for identifying of the EFDS finite model. The modelling process gives us the more precise decisions as a prediction of a temporalization procedure. The constructed technology is applied in the non-probabilistic utility theory for the information technology management problem.
Comparative analysis of interactions between the hydropyridine dicarboxylate derivatives and different proteins by molecular docking and charge density analysis
Authors: Qi Yanjiao , Zhao Yaming , Wang Xiaoe , Lu Huining , Jin Nengzhi
Published: August 2016

Molecular docking and charge density analysis were carried out to understand the geometry, charge density distribution and electrostatic properties of one of newly synthesized 4-substituted-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylates (PDE), which is regarded as the best [Formula: see text]-Glucosidase inhibitor among the hydropyridine dicarboxylate derivatives. The different bonding models of the PDE molecule in the active sites of proteins Human serum albumin (HSA) and Saccharomyces cerevisiae [Formula: see text]-glucosidase (SAG) are firstly compared, which is important to understand the different intermolecular interactions between drug-transport protein and drug-target protein. The deformation density maps suggest that the electron densities of the PDE molecule are redistributed when it presents in the active sites. When the molecule presents in the active site of the SAG, it is evident to find that the negative region does not appear at the vicinity of the oxygen atoms on one of the carboxylic acid dimethyl ester group. Frontier molecular orbital density distributions for the PDE molecule are similar in all forms. The highest occupied molecular orbital (HOMO) and lowest occupied molecular orbital (LUMO) energy gaps in the active sites are higher than that of the molecule in pure solution phase. It is generally noticed that all of the orientations of the dipole moment vectors are reoriented in both active sites. These fine details at electronic level allow to better understand the exact drug-transport protein and drug-target protein interactions.
Some shaper uncertainty principles for multivector-valued functions
Authors: Fei Minggang , Pan Yubin , Xu Yuan
Published: August 2016

The Heisenberg uncertainty principle and the uncertainty principle for self-adjoint operators have been known and applied for decades. In this paper, in the framework of Clifford algebra, we establish a stronger Heisenberg–Pauli–Wely type uncertainty principle for the Fourier transform of multivector-valued functions, which generalizes the recent results about uncertainty principles of Clifford–Fourier transform. At the end, we consider another stronger uncertainty principle for the Dunkl transform of multivector-valued functions.

In this paper, we consider the category Dcpo-S of [Formula: see text]-dcpos and [Formula: see text]-dcpo maps between them. This category is enriched over the symmetric monoidal closed category Dcpo. So, we are going to find weighted limits in this category. In fact, we show that the category of [Formula: see text]-dcpos has weighted limits. Finally, we give a concrete construction of some kinds of weighted limits in this category.

Published: August 2016

In this work, the catalyst silver phosphate (Ag3PO[Formula: see text] with different initial ratios of Ag[Formula: see text] and PO[Formula: see text] in aqueous solution was synthesized by a simple precipitation method from AgNO3 and NH4H2PO4 which were used as the precursor. After that, the prepared samples were characterized by different techniques such as field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), UV-visible diffuse reflectance spectroscopy (UV-DRS) and decomposition evolution of rhodamine B (RhB) solution. The results indicate that the initial ratios of Ag[Formula: see text]/PO[Formula: see text] in aqueous solution can modify the morphology and also it can significantly affect the photocatalytic performance. During photocatalytic process, the rich Ag[Formula: see text] ion Ag3PO4 can form the surface plasmon resonance (SPR) of Ag nanoparticles, which inhibit the reduction of Ag3PO4 resulting in higher photocatalytic activity and stability.
A novel parallel algorithm for computing the mooring line based on lumped-mass method
Authors: Zhu Zhong-Xian , Yin Yong , Movania Muhammad Mobeen
Published: August 2016

Dynamic modeling and simulation of the mooring system are the key technologies in anchor handling simulator (AHS). Built up the mooring line’s dynamics model based on lumped-mass method (LMM), and fourth-order Runge–Kutta method was used to solve the model; because of the huge amounts of calculation in the model’s solving, the very time-consuming process brings great impact on the real-time, fidelity and immersed feeling in the anchor handling scene simulation, seriously hindered its application in AHS. A novel parallel algorithm was proposed to speed-up the model’s solving process by taking the advantages of graphic processing units (GPU’s) massive parallel computing and float point computing capability. The model’s solving process was implemented on vertex shader based on the transform feedback (TF) mechanism in modern GPU. Experimental results show that, the new algorithm reduced the calculating time largely without losing accuracy, and can finally realize the real-time solving and simulation.
A Derivation of Aharonov–Casher Phase and Another Adiabatic Approximation for Pure Gauge Under General Rashba Effects
Authors: Kondo Kenji
Published: August 2016

Spin filters using spin–orbit interaction (SOI) are very important in the field of spintronics. Therefore, a theory of devices using SOI is necessary for designing the spin filters. The spin-filtering devices can be used to generate and detect spin polarized currents. Many researchers have reported on the spin-filters using linear Rashba SOI. However, the spin-filters using square and cubic Rashba SOIs are not yet reported. This is surely because the Aharonov–Casher (AC) phases acquired under square and cubic Rashba SOIs are ambiguous. In this paper, we try to derive the AC phases acquired under [Formula: see text]th order Rashba SOIs, which we call general Rashba SOIs, using non-Abelian SU (2) gauge theory. As a result, we have successfully derived these AC phases without completing the square methods which is useless except for linear Rashba SOI. In the process of derivation of AC phases, we have also found another expression of adiabatic approximation for a pure gauge. This finding will lead to the starting point for deeply understanding the adiabatic approximation. Using the above AC phases under general Rashba SOIs, we investigate the spin filter effect in Aharonov–Bohm (AB) ring with double quantum dots (QDs) under general Rashba SOIs. The spin transport is investigated from left nanowire to right nanowire in this structure within tight binding approximation. Especially, we focus on the difference of spin filter effects among general Rashba SOIs. We have obtained the penetrating magnetic flux dependence of spin polarization for the AB ring subject to general Rashba SOIs. It is found that the perfect spin filtering is achieved for all the Rashba SOIs. This result indicates that this AB ring under general Rashba SOIs can be a promising device for spin current generation without ferromagnetic metals. Moreover, this device under different order Rashba SOI behaves in totally different ways in response to penetrating magnetic flux, which is attributed to [Formula: see text] times rotation of directions of the effective magnetic field in the in-plane momentum. This fact means that we can determine the order of Rashba SOIs according to the peak position. We consider that this is very useful for many researchers.

Published: August 2016

Giant cell tumor of tendon sheath is one of the most common soft tissue tumors of the hand. These tumors typically occur in the third or fourth decade of life and present as solitary nodules on a single digit. Currently, the greatest reported number of lesions found within a single digit is five. Although uncommon, giant cell tumor of tendon sheath does occur in the pediatric population. Herein we present a report of a rare case of GCTTS in a child in which seven lesions were identified within a single digit—the greatest number of lesions within a single digit reported to date.
Enteroscopic Management of Ectopic Varices in a Patient with Liver Cirrhosis and Portal Hypertension
Authors: Watson G. A. , Abu-Shanab A. , O’Donohoe R. L. , Iqbal M.
Published: August 2016

Portal hypertension and liver cirrhosis may predispose patients to varices, which have a propensity to bleed and cause significant morbidity and mortality. These varices are most commonly located in the gastroesophageal area; however, rarely ectopic varices may develop in unusual locations outside of this region. Haemorrhage from these sites can be massive and difficult to control; thus early detection and management may be lifesaving. We present a case of occult gastrointestinal bleeding in a patient with underlying alcoholic liver disease where an ectopic varix was ultimately detected with push enteroscopy.

Published: August 2016

The article deals with the lost library of the poet Friedrich von Logau. Although an heir of a handsome collection, which he expanded vigorously, he left to his son no more than a dozen books, which are preserved in the Herzogin Anna Amalia Library at Weimar today – among thousands of new purchases by the son, Balthasar Friedrich von Logau.

Der Beitrag spricht über die verschwundene Bibliothek des Dichters Friedrich von Logau. Obwohl er Erbe einer stattlichen Büchersammlung war, diese selbst nach Kräften vermehrte, hinterließ er seinem Sohn nicht mehr als ein Dutzend Bücher, die heute in der Herzogin Anna Amalia Bibliothek in Weimar – unter Tausenden Neuerwerbungen des Sohnes Balthasar Friedrich von Logau – aufbewahrt werden.
Transformationen Vergils in der spätmittelalterlichen Literatur: Sangspruchdichtung und Ablassverzeichnisse
Authors: Mierke Gesine
Published: August 2016

The narrative complex about Vergil the magician, which is increasingly present in the Latin literature since the 11th century as well as in the vernacular literature since the 13th century, gave rise to various researches. Not all testimonials of reception are however documented, especially those of the late medieval literature. Primarily genres like the Mirabilia Romae or the Indulgentiae ecclesiarum Urbis Romae remained widely unconsidered on that premise although several facets of Vergil as a literary figure were being invoked here. Moreover, only little attention is paid so far to the question of the function that corresponds to the Vergil-narratives within the individual texts. This contribution focuses on the transformations of Vergil as a literary figure within the Indulgentiae ecclesiarum Urbis Romae as well as their functionalization in these texts. With a view to the Sangspruchdichtung of the 14th and 15th century, the possible interpretations of the narratives are being explored.

Der narrative Komplex um den Zauberer Vergil, der in der lateinischen Literatur ab dem 11. Jahrhundert und in den volkssprachigen Literaturen ab dem 13. Jahrhundert zunehmend präsent ist, hat zu verschiedenen Untersuchungen Anlass gegeben. Dennoch sind nicht alle Rezeptionszeugnisse vor allem der spätmittelalterlichen Literatur erfasst. Insbesondere Gattungen wie die Mirabilia Romae oder die Ablassverzeichnisse (Indulgentiae ecclesiarum urbis Romae) blieben unter dieser Prämisse weitgehend unberücksichtigt, obwohl hier verschiedene Facetten Vergils als literarische Figur aufgerufen werden. Überdies hat man der Frage, welche Funktion den Vergil-Narrativen in den Einzeltexten zukommt, bisher nur wenig Beachtung geschenkt. Im Zentrum des Beitrags stehen die Transformationen Vergils als literarische Figur in den Indulgentiae ecclesiarum urbis Romae und deren Funktionalisierung in diesen Texten. Mit Blick auf die Sangspruchdichtung des 14. und 15. Jahrhunderts werden die Deutungsmöglichkeiten der Narrative ausgelotet.
Craftsmen, Artillery, and War Production in Renaissance Florence
Authors: Ansani Fabrizio
Published: August 2016

This article examines technological developments in the production of weapons, especially firearms, during the Florentine Quattrocento, from the early conflicts against the Visconti (1423–1433) until the first years of the Pisan War (1494–1499). The aim is an analysis of the qualitative standards achieved by gunmakers and gunpowder makers before and after the appearance and the assimilation of the most efficient French ordnance into Italian warfare. Data have been collected from the State Archive of Florence. Fiscal sources (catasto, decima) and the documentation of guilds (fabbri and speziali) provided the information on craftsmen and their workshops. The registers of military officers (Dieci di Balìa and Otto di Pratica) show the leading role that public demand played in the introduction of technical changes and innovative tools such as new furnaces, bronze cannons, cast iron shot, and corned powder. The same records provide information about the spread of innovations and the migration of artisans. The results of the research demonstrate that the commune actually enhanced its management of war production, fostering improvements in the fabrication of firearms and a significant growth in the weapons market. Numerous artisans were employed in manufacturing munitions and in supplying soldiers and fortresses, and some famous artists, such as Andrea del Verrocchio, may have been involved in casting beautiful firearms for the Florentine Republic in this period.

Published: August 2016

Epigenetic modifications are involved in the pathogenesis of cancer, and histone deacetylase inhibitors are considered potential therapeutic agents. Histone tails undergo acetylation at lysine residues, which is associated with transcriptional activation. However, previous studies indicated that as histone deacetylase inhibitors, both (−)-epigallocatechin-3-gallate and valproic acid presented the effects of downregulation of amyloid precursor protein expression, which resulted in the induction of apoptosis. The downregulation of amyloid precursor protein, instead of conventionally activating gene expression as histone deacetylase inhibitor, was attractive. However, there was no relevant report on the correlation of the expression of amyloid precursor protein and histone deacetylase 1 in cancer. In the present study, we detected the expression of amyloid precursor protein and histone deacetylase 1 in hepatocellular carcinoma and adjacent tissues, as well as the correlations among histone deacetylase 1, amyloid precursor protein, and tumor stage. The results showed that the expressions of amyloid precursor protein and histone deacetylase 1 were significantly higher in hepatocellular carcinoma tissues than that in adjacent tissues ( P < .05), however, there was no statistical difference between amyloid precursor protein and histone deacetylase 1 with tumor stages. The present findings provided more foundation for the study on amyloid precursor protein metabolism in cancer, especially on the regulation of amyloid precursor protein by histone deacetylases.

Published: August 2016

Purpose

Allogeneic hematopoietic stem-cell transplantation (allo-HSCT) is one important treatment option for patients with aggressive adult T-cell leukemia/lymphoma (ATLL). Mogamulizumab (anti-CCR4 monoclonal antibody; Mog) was recently approved as a treatment for ATLL in Japan. Major concerns exist about the possible adverse effects of pretransplantation Mog because Mog depletes regulatory T cells for several months. We assessed the impact of pretransplantation Mog on clinical outcomes after allo-HSCT.

Patients and Methods

We included 996 allo-HSCT recipients age 70 years or younger with aggressive ATLL who were given the diagnosis between 2000 and 2013 and who received intensive chemotherapy by multiple chemotherapeutic drugs as first-line therapy. Before allo-HSCT, 82 patients received Mog with a median interval of 45 days from the last Mog to allo-HSCT.

Results

Pretransplantation Mog was associated with an increased risk of grade 3 to 4 acute graft-versus-host disease (GVHD; relative risk, 1.80; P < .01) and refractoriness to systemic corticosteroid for acute GVHD (relative risk, 2.09; P < .01). One-year cumulative incidence of nonrelapse mortality was significantly higher in patients with pretransplantation Mog compared with those without (43.7% v 25.1%; P < .01). The probability of 1-year overall survival was also significantly inferior in patients with pretransplantation Mog compared with those without (32.3% v 49.4%; P < .01). In particular, use of Mog with intervals < 50 days to allo-HSCT was associated with a dismal clinical outcome.

Conclusion

Pretransplantation Mog was significantly associated with an increased risk of GVHD-related mortality, which supports the relevance of CCR4-expressing Tregs after allo-HSCT in humans. In clinical practice, Mog should be cautiously used for patients with ATLL who are eligible for allo-HSCT.
Applying Computer Models to Realize Closed-Loop Neonatal Oxygen Therapy
Authors: Morozoff Edmund , Smyth John A. , Saif Mehrdad
Published: August 2016

BACKGROUND:

Within the context of automating neonatal oxygen therapy, this article describes the transformation of an idea verified by a computer model into a device actuated by a computer model. Computer modeling of an entire neonatal oxygen therapy system can facilitate the development of closed-loop control algorithms by providing a verification platform and speeding up algorithm development.

METHODS:

In this article, we present a method of mathematically modeling the system’s components: the oxygen transport within the patient, the oxygen blender, the controller, and the pulse oximeter. Furthermore, within the constraints of engineering a product, an idealized model of the neonatal oxygen transport component may be integrated effectively into the control algorithm of a device, referred to as the adaptive model. Manual and closed-loop oxygen therapy performance were defined in this article by 3 criteria in the following order of importance: percent duration of SpO2 spent in normoxemia (target SpO2 ± 2.5%), hypoxemia (less than normoxemia), and hyperoxemia (more than normoxemia); number of 60-second periods <85% SpO2 and >95% SpO2; and number of manual adjustments.

RESULTS:

Results from a clinical evaluation that compared the performance of 3 closed-loop control algorithms (state machine, proportional-integral-differential, and adaptive model) with manual oxygen therapy on 7 low-birth-weight ventilated preterm babies, are presented. Compared with manual therapy, all closed-loop control algorithms significantly increased the patients’ duration in normoxemia and reduced hyperoxemia (P < 0.05). The number of manual adjustments was also significantly reduced by all of the closed-loop control algorithms (P < 0.05).

CONCLUSIONS:

Although the performance of the 3 control algorithms was equivalent, it is suggested that the adaptive model, with its ease of use, may have the best utility.

Published: August 2016

We analyzed the structure of coronal features, using data on the March 20, 2015 total solar eclipse. The Ludendorff index characterizing the flattening of the corona is 0.09. The solar corona structure in the Northern and Southern hemispheres corresponds to the maximum and post-maximum phases of solar activity, respectively. The asynchronous development of magnetic activity in the Sun’s Northern and Southern hemispheres caused a substantial asymmetry of coronal features observed at the reversal of polar magnetic fields in the current cycle. The polar ray structures in the Southern Hemisphere are associated with the polar coronal hole, while in the Northern Hemisphere a polar hole has not been formed yet. We examine the relation between large-scale magnetic fields and location of high coronal structures.
New capabilities of Chetaev´s model
Authors: Савин Михаил , Savin Mihail , Израильский Юрий , Izrailsky Yuriy
Published: August 2016

This paper considers anomalies in the magnetotelluric field in the Pc3 range of geomagnetic pulsations. We report experimental data on Pc3 field recordings which show negative (from Earth’s surface to air) energy fluxes Sz<0 and reflection coefficients |Q|>1. Using the model of inhomogeneous plane wave (Chetaev’s model), we try to analytically interpret anomalies of energy fluxes. We present two three-layer models with both electric and magnetic modes satisfying the condition |Qh|>1. Here we discuss a possibility of explaining observable effects by the resonance interaction between inhomogeneous plane waves and layered media.

Purpose

To assist the pharmacy clinician engaged in nutrition support in staying current with the most pertinent literature.

Methods

Several experienced board-certified clinical pharmacists engaged in nutrition support therapy compiled a list of articles published in 2014 and 2015 that they considered to be important to their practice. Only those articles available in print format were considered for potential inclusion. Articles available only in preprint electronic format were not evaluated. The citation list was compiled into a single spreadsheet where the author participants were asked to ascertain whether they considered the paper important to nutrition support pharmacy practice. A culled list of publications was then identified whereby the majority of author participants (at least 5 out of 8) considered the paper to be important.

Results

A total of 108 articles were identified; 36 of which were considered to be of high importance. An important guideline article published in early 2016, but not ranked, was also included. The top-ranked articles from the primary literature were reviewed.

Conclusion

It is recommended that the informed pharmacist, who is engaged in nutrition support therapy, be familiar with the majority of these articles.
The automaton in all of us: GIFs, cinemagraphs and the films of Martin Arnold
Authors: Bering-Porter David
Published: August 2016

The work of the experimental film-maker, Martin Arnold, has been described as part structural film, part rap, and part seizure or stutter. Using an optical printer to manipulate 16mm films, Arnold plays with the movement and timing of a film to create an effect like that of a DJ scratching a record: the motion of the film seems to seize, to convulse in repetitive patterns of time. This article focuses on the first and last of a trio of Arnold’s experimental films that include Pièce Toucheé (1989), Passage à l’acte (1993), and Alone. Life Wastes Andy Hardy (1998). The perverse motions studies that Arnold creates are generated through footage taken from Hollywood and detourned to reveal another set of meanings that appear beneath the surface of the original narrative. Arnold’s films belong both to experimental film and to new media and they reveal something about a distinctive pattern of time: a tightening temporal loop that is characteristic of both new media and global capitalism, both of which exhibit a temporality that serves to manage the status quo and to deny real change. This article will trace out the connections between Arnold’s films and certain digital moving images, such as the gif and cinemagraph, in order to better understand the small temporal loop, which expresses something important and unique about the temporality of our time.

‘A trick with rebounds’: Portugal, Zambia and the Rhodesian crisis (1967–1968)
Authors: Barroso Luís
Published: August 2016

This article analyses the Portuguese government’s political approach to Zambia between 1967 and 1968. During this time, South Africa was assuming its strategic preponderance in southern Africa while Zambia was the country most affected by the sanctions imposed on Southern Rhodesia. This provided the Portuguese government with an opportunity to persuade the Zambian prime minister Kenneth Kaunda to reject the presence of African liberation movements in Zambia in exchange for transport facilities during the boycott of Southern Rhodesia. However, Kaunda refused to collaborate in this way. Kaunda did not want Portuguese involvement with South Africa and Rhodesia in Angola and Mozambique and sought to offer his good offices in an attempt to end the war in those territories. The firmness of his decision was down to three main reasons: he did not want to be branded a collaborator with the ‘white redoubt’; he did not want Angola and Mozambique to become ‘new Rhodesias’; and he was absolutely sure of the unconditional support of the United Kingdom and the United States.
A representação do cinema no Jornal Português: da capital das vedetas à agenda de António Lopes Ribeiro
Authors: Vieira Lisboa Ricardo
Published: August 2016

Entre 1938 e 1951 a Sociedade Portuguesa de Actualidades Cinematográficas produziu para o Secretariado da Propaganda Nacional (SPN) e para o seu sucessor, o Secretariado Nacional de Informação, Turismo e Cultura Popular (SNI), sob a supervisão de António Lopes Ribeiro, um jornal de atualidades nacionais intitulada Jornal Português. Dos 101 números deste jornal, formado por 510 reportagens, este artigo preocupa-se com apenas 15 dessas reportagens que estão relacionadas com a representação do cinema, especialmente as reportagens que acompanham a visita de vedetas do cinema internacional a Portugal, que acompanham a rodagem de filmes nacionais, da sua estreia e das respetivas entregas de prémios. O propósito é analisar de que forma foi o cinema instrumentalizado pelo Estado Novo como forma de propaganda interna durante o período da Segunda Guerra, e anos seguintes, através destas reportagens. E de que forma António Lopes Ribeiro se serviu do Jornal Português como ferramenta de autopromoção e de justificação da sua importância cimeira do cinema português como “cineasta do regime”.

Published: August 2016

En este artículo se analizan las principales contribuciones realizadas desde las ciencias sociales al estudio del noticiario cinematográfico producido en Argentina. Se toma en cuenta tanto la historia del género como las conceptualizaciones propuestas desde las perspectivas semiótica y sociohistórica y se define su especificidad a partir del estudio de aquello que lo homologa y lo diferencia del cine documental y la prensa gráfica. El aporte del mismo consiste, por lo tanto, en sistematizar, analizar y poner en discusión los conceptos y teorizaciones formulados hasta la fecha para arribar, a partir de ellos, a una perspectiva analítica original que construya al noticiario cinematográfico como un objeto de estudio sociológico.

Misleading minds and playing with senses in the works of H.G. Wells
Authors: Briatková Veronika
Published: August 2016

Wings flapping in the dark, a scientist who is able to be present in two places at once as a result of an accident in the laboratory, and unknown creatures hiding in the shadows. This paper focuses on those works of English writer H.G. Wells (1866-1946) which create mystery by playing with human perception and the human senses. In these stories, the mysteries might have a real cause, or they might be a result of confusion. Either way, it certainly makes the characters question the reliability of their minds. They shudder with fear, and sometimes they are on the verge of losing their sanity. These phenomena are examined from the perspective of cognitive approaches. The analysis focuses on mental processing and how it influences the mental stability of the characters in question. One of the questions asked is what kinds of responses are elicited by these mysteries involving potentially misled senses.
Electrical Interface for a Self-Powered MR Damper-Based Vibration Reduction System
Authors: Jastrzębski Łukasz , Sapiński Bogdan
Published: August 2016

The study investigates the behaviour of an electrical interface incorporated in a MR damper-based vibration reduction system powered with energy recovered from vibration. The interface, comprising the R, L and C elements, is connected in between the coil in an electromagnetic electric generator and the control coil in the MR damper and its function is to convert the output voltage from the generator. The interface model was formulated and computer simulations were performed to find out how the parameters of the interface should influence the frequency responses of the vibration reduction system.
The Motivic Igusa Zeta Series of Some Hypersurfaces Non-Degenerated with Respect to their Newton Polyhedron
Authors: Schoutens Hans
Published: August 2016

We describe some algorithms, without using resolution of singularities, that establish the rationality of the motivic Igusa zeta series of certain hypersurfaces that are non-degenerated with respect to their Newton polyhedron. This includes, in any characteristic, the motivic rationality for polydiagonal hypersurfaces, vertex singularities, binomial hypersurfaces, and Du Val singularities.
Application of a two-phase thermosyphon loop with minichannels and a minipump in computer cooling
Authors: Bieliński Henryk , Mikielewicz Jarosław
Published: August 2016

This paper focuses on the computer cooling capacity using the thermosyphon loop with minichannels and minipump. The one-dimensional separate model of two-phase flow and heat transfer in a closed thermosyphon loop with minichannels and minipump has been used in calculations. The latest correlations for minichannels available in literature have been applied. This model is based on mass, momentum, and energy balances in the evaporator, rising tube, condenser and the falling tube. A numerical analysis of the mass flux and heat transfer coefficient in the steady state has been presented.
Thermodynamic analysis of the advanced zero emission power plant
Authors: Kotowicz Janusz , Job Marcin
Published: August 2016

The paper presents the structure and parameters of advanced zero emission power plant (AZEP). This concept is based on the replacement of the combustion chamber in a gas turbine by the membrane reactor. The reactor has three basic functions: (i) oxygen separation from the air through the membrane, (ii) combustion of the fuel, and (iii) heat transfer to heat the oxygen-depleted air. In the discussed unit hot depleted air is expanded in a turbine and further feeds a bottoming steam cycle (BSC) through the main heat recovery steam generator (HRSG). Flue gas leaving the membrane reactor feeds the second HRSG. The flue gas consist mainly of CO2 and water vapor, thus, CO2 separation involves only the flue gas drying. Results of the thermodynamic analysis of described power plant are presented.
Effectiveness of high temperature innovative geometry fixed ceramic matrix regenerators used in glass furnaces
Authors: Wołkowycki Grzegorz
Published: August 2016

The paper presents the effectiveness of waste heat recovery regenerators equipped with innovative ceramic matrix forming an integral part of a real glass furnace. The paper full description of the regenerators’ matrix structure with its dimensions, thermo-physical properties and operating parameters is included experimentally determined was the effectiveness of the regenerators has been descrbed using the obtained experimental data such as the operating temperature, gas flows as well as the gases generated during the liquid glass manufacturing process. The effectiveness values refer not only to the heating cycle when the regenerator matrix is heated by combustion gases but also to the cooling cycle in which the matrix is cooled as a result of changes in the direction of the flowing gas. On the basis of the determined effectiveness values for both cycles and measurement uncertainties it was possible, to calculate the weighted average efficiency for each of the regenerators.

A case study on service recovery: Frontline employees’ perspectives and the role of empowerment
Authors: Schumacher Satu , Komppula Raija
Published: August 2016

The aim of this study was to improve our understanding of how frontline employees cope with service recovery situations and recover from them. It also takes a closer look at employee empowerment. This work represents a qualitative case study, and investigates the topic from the perspective of frontline employees. Data collection is implemented by interviewing the case hotel’s frontline personnel. A content analysis method was utilised to analyse the collected data. The findings suggest that the support of colleagues is more crucial in coping with service recovery situations and recovering from them than the support of managers. Personality traits also play a role. A theoretical scheme of the service recovery process from the perspective of frontline employees is developed from the analysis of the interviews. The findings indicate that written instructions would assist employees in service recovery situations.
E-beam crosslinked nanogels conjugated with monoclonal antibodies in targeting strategies
Authors: Adamo Giorgia , Grimaldi Natascia , Sabatino Maria Antonietta , Walo Marta , Dispenza Clelia , Ghersi Giulio
Published: August 2016

Poly(N-vinyl pyrrolidone)-based-nanogels (NGs), produced by e-beam irradiation, are conjugated with monoclonal antibodies (mAb) for active targeting purposes. The uptake of immuno-functionalized nanogels is tested in an endothelial cell line, ECV304, using confocal and epifluorescence microscopy. Intracellular localization studies reveal a faster uptake of the immuno-nanogel conjugate with respect to the ‘bare’ nanogel. The specific internalization pathway of these immuno-nanogels is clarified by selective endocytosis inhibition experiments, flow cytometry and confocal microscopy. Active targeting ability is also verified by conjugating a monoclonal antibody which recognizes the αvβ3 integrin on activated endothelial cells. Epifluorescence images of the ‘wound healing assay’ on ECV304 cells provide evidence of nanogels localization only in the target cells. Therefore, the immuno-nanogels produced have the potential to recognize specific cell types in heterogeneous systems, which makes them promising candidates for targeted drug delivery applications.
Anemia in Intensive Care: A review of Current Concepts
Authors: Rawal Gautam , Kumar Raj , Yadav Sankalp , Singh Amrita
Published: August 2016

Anemia in patients admitted to an intensive care unit is common and affects almost all critically ill patients. The intensivist is faced with the challenge of treating multifactorial etiologies, mainly bleeding and blood loss due to phlebotomy and decreased erythropoiesis. Red cell transfusion, the most common treatment for anemia, comes with associated risks, which may further reduce the chance of survival of these patients. The best evidence suggests the practice of restrictive RBC transfusion (transfusion at Hb<7 g/dl).

In this article, the etiopathogenesis of the anemia in critically ill is reviewed, and current opinion on the pros and cons of various management strategies are discussed with emphasize on restrictive transfusion policy.
