Theoretical Determination of a Thermogravimetric Model of Oak Cork (Quercus variabilis) Using Málek Kinetic Analysis
Authors: Shangguan Weiwei , Chen Zhangjing , Song Xiaozhou , Lei Yafang
Published: May 2017

The purpose of this study was to determine the expression of a kinetic model and the determination of kinetic parameters for cork. Thermal analysis kinetics of cork and impurities (sclereids and lenticels) were studied by thermogravimetric (TG) curves. The Málek method was used to obtain kinetic parameters in this experiment. Reconstruction models of y(α) and z(α) were compared with standard curves to determine appropriate kinetic models. The results showed that the RO(n) model was suitable to describe the dynamic process of cork, sclereids, and lenticels. The expressions of kinetic models were f(α) = (1 − α)4.89 for cork, f(α) = (1 − α)5.82 for sclereids, and f(α) = (1 − α)5.00 for lenticels. The natural log values ln A were 19.56, 28.90, and 28.88 ln s−1 for cork, sclereids, and lenticels, respectively. Fitting errors of parameters for cork, sclereids, and lenticels were less than 5 percent. The fitted conversion rate and curves of mass fraction were in good agreement with experimental data. Obtaining the kinetic model and parameters provides a basis for prediction of thermal properties of cork.
The beautiful, the bizarre, and the brutal: Dario Argento’s rhetoric of simulational aesthetics
Authors: Hurley Gavin F.
Published: May 2017

This article develops a theory of rhetoric to explain why contemporary audiences still enjoy and adhere to Dario Argento’s early horror films, specifically films spanning the years 1970 to 1982. The theory blends Jean Baudrillard’s concepts of hyperreality and simulation with Kenneth Burke’s understanding of rhetoric, persuasion and transcendence to explain how Argento’s cinematic vision transports viewers to a plane of aesthetic simulation whereby ‘pure persuasion’ unfolds. By illustrating specific examples from his films, including Suspiria (1977), Inferno (1980), Tenebrae (1982) and The Bird with the Crystal Plumage (1970), this article plots Argento’s evolution – and eventual abandonment – of the aesthetic simulation approach. This article argues that his aesthetically simulative approach coincided with the international success of his earlier films in the late 1970s and early 1980s: success that has significantly waned with his more recent films. This trend demonstrates the persuasive power held by Argento’s early art: a unique rhetoric that can benefit the horror genre as a whole.
No, everything is not all right: Supernatural horror as pessimistic argument
Authors: Stoneman Ethan , Packer Joseph
Published: May 2017

Historically, common belief and opinion have not been overly receptive to the tenets of philosophical pessimism. Ideas such as ‘Progress is illusory’, ‘The world is malignantly useless’, and ‘Life itself is perhaps little more than a constant dying’ simply rub most people the wrong way – and understandably so. According to the philosophical pessimist Peter Zapffe, when confronted by pessimistic ideas and argumentation most people have recourse to four ingrained, anti-pessimistic strategies: distraction, isolation, anchoring, and sublimation. Collectively, these strategies constitute a group of rhetorical liabilities that go a long way in explaining pessimism’s ongoing rhetorical inefficacy. Responding to that impasse, this article attempts to vindicate pessimism of its apparent rhetorical failing, arguing that pessimism can achieve rhetorical viability by foregoing traditional models of argumentation and opting instead for a less straightforwardly rational mode of argument. Such a mode, we claim, is exemplified by a particular strand of supernatural horror literature, namely, weird fiction. Through an examination of several representative weird tales, we show how weird fiction, by creating a sense of uncanny fear, functions rhetorically to undermine readers’ adherence to anti-pessimistic biases. In so doing, weird fiction fosters the creeping sense that all might not be right with the world.
Fault lines in Under the Skin (Glazer, 2013): An ethics and aesthetics of the ‘monstrous’
Authors: Roche David
Published: May 2017

An adaptation of Michel Faber’s 2000 novel about alien invasion that updates the scifi horror tradition of the 1970s in an art-cinema mode, Under the Skin (Glazer, 2013) offers a stellar example of the ‘monstrous’ as both figure and form. Generally speaking, the interstitiality of the ‘monstrous’ demands strategies grounded in the disconnection between categories (image and sound, diegetic and nondiegetic), some of which have become horror movie clichés. Under the Skin is no exception. Its aesthetics of instability, correlated to a ‘monstrous’ figure that casts a defamiliarizing gaze on our world before attempting to ‘become human’, produces a complex subtext on contemporary alienation and identity politics, that puts the viewer in a position where he or she must both take moral responsibility for the categories he or she constructs (such as the ’monstrous’), and experience the mysterious physicality at the core of life itself.
Fear and utopia in the millennial zombie: Digging deep inside Snyder’s Dawn of the Dead
Authors: Cloyd Nathanael J.
Published: May 2017

This article analyses Zack Snyder’s 2004 remake of Dawn of the Dead through Fredric Jameson’s three horizons of textual interpretation to demonstrate how the film, as an example of the third-strain millennial zombie narrative, supports a socially conservative ideology while simultaneously pointing to the Utopian possibility of communal action in the face of an overwhelming threat. The first horizon compares the formal differences of the visual effects between the remake and Romero’s 1978 original, showing how the removal of the original’s campy special effects repurposes the millennial zombie as a threat to conservative culture, not a vehicle for social satire as Romero had hoped. The second horizon, viewing the remake as a post-9/11 film, sees the symbolic conflict of social classes globalize and manifest as the human-capitalist-American bourgeoisie versus the zombie as the anti-American-terrorist proletariat. The third horizon, focusing on the historic progression of the means of production, sees the film as functioning through the politics of fear and the personalization of fear to serve as a conservative, capitalist economic motivator, while simultaneously inspiring the Utopian hope that humanity might be able to work together as a community.
On situating painting: An interview with Karin Kneffel
Authors: Manghani Sunil
Published: May 2017

Karin Kneffel came to prominence in the 1990s, known for her finely rendered portraits of animals, interiors and still-life paintings. Her handling of light, shadow and the complex interplay of reflective surfaces leads to challenging illusionist spaces. Through striking juxtapositions, foreshortening and exaggerated scales, Kneffel transforms otherwise overlooked objects. In this interview, the artist offers critical reflections on her practice. The interview is divided into three strands: (1) Situated Painting, which begins with specific considerations about the political conditions within which one ‘works’ as an artist; (2) Situations of Painting, which turns attention to painting as medium and form; and (3) Situating Painting, which examines both practical and aesthetic considerations of displaying work, and in particular an exhibition at the Mies van der Rohe Pavilion in Barcelona.
Baggage reclaim: Some thoughts on feminism and painting
Authors: Fortnum Rebecca
Published: May 2017

This article calls for a reappraisal of the feminist discussion around painting in relation to contemporary practices by women, suggesting that all painting by women has something to offer feminist critical thought. Playfully using Judy Chicago’s reflections and strategies as a frame, the article explores how contemporary painters have engaged with the histories and communities of women to form new models of scholarship and practice. It examines the projects of painters Melissa Gordon, Nadia Hebson and the Obscure Secure group (Jacqueline Utley, Hayley Field and Claudia Böse) whose artwork forms a ‘live’ response to the legacy of little known and undervalued women artists. The article concludes by examining the notion of the painterly gesture and develops a feminist context in which to examine the materiality and processes of painting, with reference to the perspectives of Dana Schutz and Jutta Koether among others. It suggests Helen Molesworth’s historically defined quality of ambivalence can be seen resurfacing as a critical position within contemporary painting by women.
‘Something is said ...’: A conversation with Maria Chevska
Authors: Taylor Brandon
Published: May 2017

In this conversation, the painter Maria Chevska and the author discuss the notion of commitment in painting as presented in Sartre’s writings of the 1940s, in Chevska’s current practice and in her exhibition at the Vane Gallery, Newcastle, England, in 2014, and in the wider world of contemporary painting today. They range over questions of attitude, manner, materials, source material and a recent article by David Joselit on ‘transitivity’ in painting as a way of achieving contact with the register of contemporary events.
Commitment in painting
Authors: Docherty Thomas
Published: May 2017

This introductory piece situates Sartre’s What is Literature? in a historical and theoretical context. Historically, it points out that it is shaped by issues of collaboration during the Occupation of France in World War II; and, consequently, when writers such as Robert Brasillach are executed for collaboration, it sees literature as a matter of life and death. Theoretically, it addresses the idea of commitment in both writing and painting; and it addresses Sartre’s argument in terms advanced by Adorno’s criticism of Sartrean ideas of commitment and existentialist choice. Sartre distinguishes prose literature from other arts, including especially painting, and claims that prose, in describing the world, reveals fundamental truths about persons; and, once those truths are revealed, they pose a question to the reader of whether she wishes to change the facts of the world. For Sartre, ‘parler, c’est agir’. This is his ‘commitment’, and it devolves into a choice between capitalism and communism. Adorno shows that Sartre is interested in choice in merely abstract terms, and not in material and empirical choices that are made. The piece examines the relation between ‘parler’ and ‘agir’ specifically in terms of the actions made by and on paintings, to argue that what is really at stake in any contemporary political choice is the radical potential not of prosaic content but of aesthetic form.

The Role of Mere Closeness: How Geographic Proximity Affects Social Influence
Authors: Meyners Jannik , Barrot Christian , Becker Jan U. , Goldenberg Jacob
Published: May 2017

Geographic proximity has become increasingly relevant due to the growing number of marketing services that use consumers’ geographic locations, thus increasing the importance of gaining insights from this information. In five studies (both field and experimental), the authors analyze the effect of geographic proximity on social influence and demonstrate that not only social proximity but also perceived homophily can trigger social influence. They find that this effect holds under alternative representations of geographic distance and is confirmed for a range of different services and even for physical goods. Furthermore, the authors show that geographic proximity has a relative effect because the social influence of a closer sender is stronger than that of a more distant sender, regardless of the absolute distances. They present managerially relevant conditions under which the influence of geographic proximity not only is comparable to other types of information such as age or gender but also provides sufficient informational value for customers to offset differences among alternatives (e.g., due to higher prices) in trade-off decisions.

Biofunctionalization of surfaces using polyelectrolyte multilayers
Authors: Hartmann Hanna , Krastev Rumen
Published: May 2017

Biomaterials play a central role in modern strategies in regenerative medicine and tissue engineering to restore the structure and function of damaged or dysfunctional tissue and to direct cellular behavior. Both biologically derived and synthetic materials have been extensively explored in this context. However, most materials when implanted into living tissue initiate a host response. Modern implant design therefore aims to improve implant integration while avoiding chronic inflammation and foreign body reactions, and thus loss of the intended implant function. Directing these processes requires an in-depth understanding of the immunological processes that take place at the interface between biomaterials and the host tissue. The physicochemical properties of biomaterial surfaces (charge, charge density, hydrophilicity, functional molecular domains, etc.) are decisive, as are their stiffness, roughness and topography. This review outlines specific strategies, using polyelectrolyte multilayers to modulate the interactions between biomaterial surfaces and biological systems. The described coatings have the potential to control the adhesion of proteins, bacteria and mammalian cells. They can be used to decrease the risk of bacterial infections occurring after implantation and to achieve better contact between biological tissue and implants. In summary, these results are important for further development and modification of surfaces from different medical implants.
Burdock (Arctium lappa) Leaf Extracts Increase the In Vitro Antimicrobial Efficacy of Common Antibiotics on Gram-positive and Gram-negative Bacteria
Authors: Pirvu Lucia , Nicorescu Isabela , Hlevca Cristina , Albu Bujor , Nicorescu Valentin
Published: May 2017

This work aimed to study the potential effects of four Arctii folium extracts, 5 mg gallic [GAE] acid equivalents per 1 mL sample, on six antibiotics (Ampicillin/AM, Tetracycline/TE, Ciprofloxacin/CIP, Sulfamethoxazole-Trimethoprim/SXT, Chloramphenicol/C and Gentamicin/CN) tested on four Gram-positive (Staphylococcus aureus ATCC 6538, Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 29212, and Staphylococcus epidermidis ATCC 12228) and five Gram-negative (Proteus mirabilis ATCC 29245, Escherichia coli ATCC 35218, E. coli ATCC 11229, E. coli ATCC 8739, and Bacillus cereus ATCC 11778) bacteria. Arctii folium extracts were the whole ethanol extract/W and subsequent ethyl acetate/EA, aqueous/AQ, and chloroform/CHL fractions. Chemical qualitative analysis (HPTLC method) emphasized five main polyphenol compounds in Arctii folium polar extracts: chlorogenic acid (Rf≈0.52/0.55) and its isomer, 1,5-di-O-caffeoylquinic acid (Rf≈0.90/0.92), plus cynarin (Rf≈0.77), hyperoside (Rf≈0.68/0.64) and isoquercitrin (Rf≈0.69/0.71). Microbiological screening indicated Arctii folium polar extracts (AQ and W) efficacy on S. epidermidis ATCC 12228; the MIC values were in the range of common antibiotics, being 32 and 128 μg GAE per mL sample respectively. The unpredictable effects (stimulatory or inhibitory) of Arctii folium extracts in combination with typical antibiotics as well as a potential use of the whole ethanol extract/W for restoring the antimicrobial potency of susceptible antibiotics have also been evidenced.

Authors: Jaruszewska-Walczak Danuta
Published: May 2017

Classical solutions of initial boundary value problems for infinite systems of quasilinear parabolic differential functional equations are considered. Two type of difference schemes are constructed. We prove that solutions of infinite difference schemes approximate solutions of our differential functional problem. In the second part of the paper we show that solutions of infinite differential functional systems can be approximated by solutions of difference systems with initial boundary conditions and the systems are finite.

A complete convergence analysis for the methods is presented. The proof of the stability is based on a comparison technique with nonlinear estimates of the Perron type for given functions.

A survey on polygonal portraits of manifolds
Authors: Kobayashi Mahito
Published: May 2017

Planar portraits are geometric representations of smooth manifolds defined by their generic maps into the plane. A simple subclass called the polygonal portraits is introduced, their realisations, and relations of their shapes to the topology of source manifolds are discussed. Generalisations and analogies of the results to other planar portraits are also mentioned. A list of manifolds which possibly admit polygonal portraits is given, up to diffeomorphism and up to homotopy spheres. This article is intended to give a summary on our research on the topic, and hence precise proofs will be given in other papers.

Finite mappings and the topology of their stable sets
Authors: Berrone Lucio R. , Dieulefait Luis V.
Published: May 2017

Given a mapping f from a finite set Xn
on itself, we explore the finite topology τf
defined by the stable subsets E of Xn
; i.e., the subsets E of Xn
which satisfy f(E) ⊆ E. Necessary and sufficient conditions are found in order that a finite topology τ may correspond to the topology τf
for a certain mapping f. A number of results relating properties of topology τf
with properties of the mapping f itself are also exposed.

Fixed points in k complete metric spaces
Authors: Kikina Luljeta , Kikina Kristaq
Published: May 2017

A fixed point theorem for three mappings on a metric space into itself is proved. This result extends the results obtained in [1] from two mappings to three mappings, and after that, a generalization for an arbitrary number of mappings is obtained. As corollaries of these results we obtain the extending of Theorems of Nešić, Rhoades, Chatterjea, Rus and Kannan for an arbitrary number of mappings.

Hopf–Sikorski algebras
Authors: Heller Michael , Odrzygóźdź Zdzisław , Pysiak Leszek , Sasin Wiesław
Published: May 2017

The dual category with respect to the category of differential groups is defined and investigated. The objects of this category are algebras, called Hopf–Sikorski (H-S) algebras, the axioms of which combine the axioms of Sikorski’s algebras with modified axiomas of Hopf algebras. Morphisms of this category are structural mappings corresponding to Hopf algebras that are smooth in the sense of Sikorski. As an example, we discuss the H-S algebra of the Lorentz group.
Some general results and extreme points of p-valent functions with negative coefficients

In this paper, we further investigate the class of functions ϕ*
(n, p, λ, α) which are analytic in the open unit disk △ = {z : |z| < 1}, and involve the combinations of the representations of p-valently starlike and convex functions. We obtain several generalized results on the modified-Hadamard product of the class ϕ*
(n, p, λ, α), which extend the corresponding results obtained by Altintas et al. [Computers Math. Applic. 30(2), 9-16, (1995)]; Darwish, Aouf [Mathematical and Computer Modelling(2007), doi:10.1016/j.mcm.2007.08.016]. Futher, by fixing the second coefficient of functions in ϕ*

Existence of solutions for some nonlinear delay integrodifferential equations with nonlocal initial conditions
Authors: Yan Zuomao
Published: May 2017

The main purpose of this paper is the existence of mild solutions for a class of first-order nonlinear delay integrodifferential equations with nonlocal initial conditions in Banach spaces. We show that the solutions are given by the application of the theory of resolvent operators and the Sadovskii’s fixed point theorem. An example is presented in the end to show the applications of the obtained results.
Principle of conditioning revisited

Principle of Conditioning is a well-known heuristic rule which allows constructing limit theorems for sums of dependent random variables from existing limit theorems for independent summands. In the paper we state a general limit theorem on converegnce to stable laws, which is valid for stationary sequences and provides a link between the Principle of Conditioning and ergodic theorems.

Kelvin transform for α-harmonic functions in regular domains
Authors: Michalik Krzysztof , Ryznar Michał
Published: May 2017

We investigate conditional stable processes in a Lipschitz domain D and conditional stable processes in the image of D under the Kelvin transform. We show that, with a suitable change of time, these processes are equal in distribution. As an application, we show the equivalence of the Hardy spaces and the relative Fatou theorem for D and its image.
On optimal stopping of risk processes with regime switching
Authors: Ferenstein Elżbieta , Pasternak-Winiarski Adam
Published: May 2017

In the paper we solve a problem of optimal stopping of a risk process in two alternative settings. We assume that the main characteristics of the risk process change according to unobservable random variable. In the first model we assume that the post-disorder distributions are not known a’priori and are randomly chosen from a finite set of admissible distributions. The second model concentrates on a situation when more than one disorder is possible. For both models optimal stopping rules with respect to given utility function are constructed using dynamic programming methodology.

Remarks on uniform convergence of random variables and statistics
Authors: Niemiro Wojciech , Zieliński Ryszard
Published: May 2017

Convergence in distribution, convergece in probability, and convergence almost surely, uniform with respect to a family of probability distributions, is considered. These concepts appeared to be appropriate tools for asymptotic theory of mathematical statistics and many partial results are scattered in the literature of the subject. The aim of this note is to present a unified review of the results in a general and abstract setup. We examine a few rather paradoxical examples which hopefully shed some light on the subtleties of the underlying definitions and the role of asymptotic approximations in statistics. A motivation for considering these problems is provided by their applications.
On the random functional central limit theorems with almost sure convergence for subsequences
Authors: Rychlik Zdzisław , Szuster Konrad S.
Published: May 2017

In this paper we present functional random-sum central limit theorems with almost sure convergence for independent nonidentically distributed random variables. We consider the case where the summation random indices and partial sums are independent. In the past decade several authors have investigated the almost sure functional central limit theorems and related ‘logarithmic’ limit theorems for partial sums of independent random variables. We extend this theory to almost sure versions of the functional random-sum central limit theorems for subsequences.

Moreover, it is established that, using such contraction principle, completeness of the generalized metric space can be characterized.

The Demyanov metric in the family of convex, compact sets in finite dimensional spaces has been recently extended to the family of convex, bounded sets – not necessarily closed. In this note it is shown that these spaces are not complete and a model for the completion is proposed. A full answer is given in ℝ2 and the situation in higher dimensions is discussed.
Completion in a common supercategory of Met, UAP, wsAP and Near
Authors: Khare Mona , Tiwari Surabhi
Published: May 2017

This paper investigates the notion of approach nearness spaces. Using clusters, completion of an approach nearness space is constructed, which is a unified study of completion in the context of metric spaces, uniform approach spaces, weakly symmetric approach spaces and nearness spaces. Another generalization of completeness, called ultrafilter completeness is introduced to prove the Niemytzki–Tychonoff theorem for approach nearness spaces. Both definitions of completions are shown to be equivalent in a limit-regular approach space. Various examples are given to support the present study.
