29th ISTANBUL INTERNATIONAL FILM FESTIVAL 2010 The Istanbul International Film Festival, the largest of its kind in the country, has enriched its repertoire this year with 200 films under twenty-three categories ranging from the prestigious products of 2009 and recent films of 2010 to all time classics. Concentrated largely around the Beyoğlu quarter, where the Turkish national cinema was born, the festival stretched over two weeks, with the second week specially designed for the foreign guests. This year the foreigners had a chance to explore the magnificent city, the Cultural Capital of Europe for 2010, even longer, when the eruption of the Eyjafjallajokul volcano in Iceland paralyzed most European air traffic for several days. The opening film was the melodrama Le concert (The Concert) by Radu Mihaileanu, a France-Italy-Romania and Belgium co-production that explored the issue of identity through classical music. Among the eleven films...

TORONTO INTERNATIONAL FILM FESTIVAL 2010 HIGHLIGHTS Having leapt into the exclusive club of industry film festivals of late, the Toronto International Film Festival nevertheless marked a transitional phase this year when it unveiled the Bell Lightbox, a donated piece of downtown real estate that is now home for year-round public programming and events. And in a shift indicative of its ambition, programming for TIFF's 35th edition (9-19 September 2010) hinted at a desire to distinguish itself from a growing pool of international rivals. Though its annual selection of films from Asia is usually conservative, this year's crop of titles was notable for bringing into relief the intricacies of intra-Asia and transnational cooperation among filmmakers. Here's a look back at ten notable titles: 13 Assassins (Miike Takashi, Japan 2010)Coming off as more square - but no less wildly entertaining - than many of his previous films, Miike Takashi's latest...
The Unbearable Duration of Andy Warhol’s Films
Authors: Haladyn Julian Jason
Published: August 2019

EMPIRE OF BORING: THE UNBEARABLE DURATION OF ANDY WARHOL'S FILMSI've been quoted a lot as saying, 'I like boring things.' Well I said it and I meant it. But that does not mean I'm not bored by them.(1) Warhol's MeaninglessnessIn his 1965 film Poor Little Rich Girl, Andy Warhol presents a motionless shot of Edie Sedgwick engaged in a series of everyday activities - talking on the telephone, modelling a new coat, and the like - the first 33-minutes of which is presented out of focus. Having watched a number of Warhol's films, this opening sequence of formless shapes and disembodied voices stands out as the most difficult time I have spent attempting to "watch" a film. The difficulty with viewing Warhol's films in general stems from his employment of structuralist tactics, specifically filming with a static camera, using long-takes and not editing the film....
Yusuf Trilogy 3-DVD SET
Authors: Uhde Jan
Published: August 2019

Semih Kaplanoǧlu is today a pillar of the recent revival of Turkish cinema, its "second wave" as some call it. Together with Nuri Bılge Ceylan (Distant) and the younger German-Turkish Fatih Akın (Head On), Kaplanoǧlu has helped to propel the cinema of his country to the forefront of film's creative ferment. Kaplanoǧlu's position has been reinforced by his Yusuf Trilogy (2007-2010), the latest instalment of which, Honey, was awarded the Golden Bear at the 2010 Berlinale. Even before this, the director was a familiar face at international festivals - his Yusuf trilogy having garnered over a dozen of festival prizes and awards....
The Union of South Africa Propaganda Campaigns during the World War II
Authors: Le Roux Anli
Published: August 2019

THE UNION OF SOUTH AFRICA PROPAGANDA CAMPAIGNS DURING THE SECOND WORLD WAR (1939–1945). Part 1: The African Mirror Newsreels IntroductionAccording to Danny Schechter, when one fights a war, "there is a need to create and maintain ties of sentiment between soldiers and citizens, as well as a need for popular mobilisation and media support" (2004:25). During the Second World War the case was no different in South Africa. The Union of South Africa propaganda campaigns in all its forms were aimed at "motivating, managing, and feeding the media" - which in turn fed the nation. This was a key strategic imperative to try to build, strengthen and maintain a consensus and united front behind the war effort (Schechter, 2004:25).The significance of contemporary filmic visualisation or off-screen enactments of war experiences and their place in South African historiography of the Second World War has long been an under-researched area....
Scripture Filmmaker Cecil B. DeMille
Authors: Kozlovic Anton Karl
Published: August 2019

SCRIPTURE FILMMAKER CECIL B. DeMILLE: BIBLICAL, RELIGIOUS OR SPIRITUAL? AbstractThe legendary producer-director Cecil B. DeMille was a master of the American biblical epic who shaped the public's perceptions of Judeo-Christianity in his role as Hollywood's Sunday school teacher. Despite his exceptional narrative talents as a sacred storyteller, critics praised or condemned his Bible films according to whether they deemed him a biblical, religious or spiritual filmmaker. But what sort of Scripture filmmaker was DeMille exactly, were the critics' condemnations fair and valid, and what of the DeMille style today? Utilizing humanist film criticism as the guiding analytical lens, a selective review of the critical literature and a reading of CB's biblical oeuvre were performed to address this issue of category confusion. It was concluded that DeMille was primarily a biblical filmmaker, not a religious or spiritual filmmaker, whose scriptural oeuvre was frequently mislabeled and unjustly assessed as a consequence....
The Representation of Gays and Lesbians in South African Cinema 1985–2013
Authors: Botha Martin P.
Published: August 2019

THE REPRESENTATION OF GAYS AND LESBIANS IN SOUTH AFRICAN CINEMA 1895-2013 Despite South Africa's progressive constitution which prohibits discrimination against gays and lesbians, as well as a strong gay movement, South African cinematic images of gay men and women are limited and still at the margin of the South African film industry. One ends up with less than 20 short films, a few documentaries and less than 10 features with openly gay and lesbian characters in the past 114 years of South African cinema. Under apartheid, gay and lesbian voices in film and television were silenced. In a 20-year study of the representation of gays and lesbians in African, Asian and Latin American cinema (Botha 2003; 2012; Botha & Swinnen 2010), the author has noted that homosexual experience is unique in South Africa, precisely because of South Africa's history of racial division and subsequent resistance. South African gay identities...

Nabokov's Cinematic Afterlife
Authors: Jamrozik Żaneta
Published: August 2019

Glancing at the title of Ewa Mazierska’ s Nabokov’ s Cinematic Afterlife one might expect a book favouring a traditional approach to adaptation studies. The title pointing to the name of Vladimir Nabokov, suggests that the writer and therefore literature occupies the centre of this study. Then, a look at the book’s table of contents may assure the reader that he or she is about to read eight essays, each focused on only one film and (as one is likely to believe) one Nabokov novel. This rule of comparison seems to be in effect until the ninth chapter titled simply Vladimir Nabokov and Jean-Luc Godard. However, more detailed examination of the contents reveals that among the first eight chapters only the last one mentions the name of Nabokov and the title of his short story, The Assistant Producer, although places it beside Triple Agent, a film written and directed by...

FROM BABE RUTH TO MICHAEL JORDAN: AFFIRMING THE AMERICAN DREAM VIA THE SPORTS /FILM STAR Its drama, its personalities and its worldwide appealmeans sport is the new Hollywood- Bell and Campbell (1999: 22) Celebrity is a crucial aspect of contemporary culture and one to which both sport and film make a substantial contribution. In film, the 'star image' that has developed around individual actors is a multifaceted, complicated and sometimes contradictory phenomenon composed of the roles they have played, their carefully orchestrated public appearances and the depictions of the creation of a star's image, as well as the actual individual around whom this image has evolved. However, arguably what is most significant about individual stars is the manner through which they express facets of living in today's society, including the nature of labour in the capitalist world (Dyer, 1986: 7-8). Stars are particularly important in...
16th SHANGHAI INTERNATIONAL FILM FESTIVAL
Authors: Editor The
Published: August 2019

16th SHANGHAI INTERNATIONAL FILM FESTIVALShanghai is playing an interesting hand early into its tenure as China’s most established festival, shaped by the Chinese film industry’s dynamic growth and the Beijing International Film Festival’s upstart claim for national preeminence. It could play its ace in promoting Mainland Chinese films, yet Shanghai hasn’t exploited this potential. This leaves Asian programming as its next best card, but Asian films at its 16th edition (15–23 June 2013) lacked range and vigour, especially in its fevered Japanese and Thai line-ups. Retrospectives felt more visible this year: apart from ones dedicated to Alfred Hitchcock, Ozu Yasujiro, Oliver Stone and Tang Xiaodan, Shanghai paid a nine-film tribute to the late singer-actor Leslie Cheung on his tenth anniversary. But organizers denied the same courtesy to Anita Mui, an equally talented hyphenate who also died in 2003, and whose amity and working rapport with Cheung certainly...

Analysis of the flow and heat transfer characteristics for MHD free convection in an enclosure with a heated obstacle
Authors: Parvin S. , Nasrin R.
Published: August 2019

Finite element method based on Galerkin weighted Residual approach is used to solve two-dimensional governing mass, momentum and energy equations for steady state, natural convection flow in presence of magnetic field inside a square enclosure. The cavity consists of three adiabatic walls and one constantly heated wall. A uniformly heated circular solid body is located at the centre of the enclosure. The aim of this study is to describe the effects of MHD on the flow and thermal fields in presence of such heated obstacle. The investigations are conducted for different values of Rayleigh number (Ra) and Hartmann number (Ha). Various characteristics of streamlines, isotherms and heat transfer rate in terms of the average Nusselt number (Nu) are presented for different parameters. The effect of physical parameter (D) is also shown here. The results indicate that the flow pattern and temperature field are significantly dependent on the above mentioned parameters.

Modeling the bacterial self-organization in a circular container along the contact line as detected by bioluminescence imaging
Authors: Baronas Romas , Šimkus Remigijus
Published: August 2019

This paper presents a one-dimensional-in-space mathematical model of a bacterial selforganization in a circular container along the contact line as detected by quasi-one-dimensional bioluminescence imaging. The pattern formation in a luminous Escherichia coli colony was modeled by the nonlinear reaction-diffusion-chemotaxis equations in which the reaction term for the cells is a logistic (autocatalytic) growth function. By varying the input parameters the output results were analyzed with a special emphasis on the influence of the model parameters on the pattern formation. The numerical simulation at transition conditions was carried out using the finite difference technique. The mathematical model and the numerical solution were validated by experimental data.

Authors: Stefanovič Pavel , Kurasova Olga
Published: August 2019

In the article, an additional visualization of self-organizing maps (SOM) has been investigated. The main objective of self-organizing maps is data clustering and their graphical presentation. Opportunities of SOM visualization in four systems (NeNet, SOM-Toolbox, Databionic ESOM and Viscovery SOMine) have been investigated. Each system has its additional tools for visualizing SOM. A comparative analysis has been made for two data sets: Fisher’s iris data set and the economic indices of the European Union countries. A new SOM system is also introduced and researched. The system has a specific visualization tool. It is missing in other SOM systems. It helps to see the proportion of neurons, corresponding to the data items, belonging to the different classes, and fallen in the same SOM cell.
Lie group analysis for the effects of chemical reaction on MHD stagnation-point flow of heat and mass transfer towards a heated porous stretching sheet with suction or injection
Authors: Afify Ahmed A. A. , Elgazery Nasser S. S.
Published: August 2019

An analysis is carried out to study two dimensional stagnation-point flow of heat and mass transfer of an incompressible, electrically conducting fluid towards a heated porous stretching sheet embedded in a porous medium in the presence of chemical reaction, heat generation/absorption and suction or injection effects. A scaling group of transformations is applied to the governing equations. After finding three absolute invariants a third order ordinary differential equation corresponding to the momentum equation and two second order ordinary differential equation corresponding to energy and diffusion equations are derived. Furthermore the similarity equations are solved numerically by using shooting technique with fourth-order Runge–Kutta integration scheme. A comparison with known results is excellent. The phenomenon of stagnation-point flow towards a heated porous stretching sheet in the presence of chemical reaction, suction or injection with heat generation/absorption effects play an important role on MHD heat and mass transfer boundary layer. The results thus obtained are presented graphically and discussed.

It is now well recognised that biocontrol of pests is one of the best ecofriendly alternative for pest control. In this paper we have studied dynamical behaviours of a model for biocontrol of pests, where it is assumed that the pest is affected by a virus. Boundedness and stability of the model are studied. The effect of time-delay is investigated. Numerical simulations are carried out to illustrate our analytical findings. It is observed that the time-delay has a regulatory impact on the system. Biological implications of our results are discussed.

Robust exponential stability of nonlinear impulsive switched systems with time-varying delays
Authors: Liu Xiu , Zhong Shouming , Ding Xiuyong
Published: August 2019

This paper deals with a class of uncertain nonlinear impulsive switched systems with time-varying delays. A novel type of piecewise Lyapunov functionals is constructed to derive the exponential stability. This type of functionals can efficiently overcome the impulsive and switching jump of adjacent Lyapunov functionals at impulsive switching times. Based on this, a delay-independent sufficient condition of exponential stability is presented by minimum dwell time. Finally, an illustrative numerical example is given to show the effectiveness of the obtained theoretical results.

Hopf bifurcation and optimal control in a diffusive predator-prey system with time delay and prey harvesting
Authors: Chang Xiaoyuan , Wei Junjie
Published: August 2019

In this paper, we investigated the dynamics of a diffusive delayed predator-prey system with Holling type II functional response and nozero constant prey harvesting on no-flux boundary condition. At first, we obtain the existence and the stability of the equilibria by analyzing the distribution of the roots of associated characteristic equation. Using the time delay as the bifurcation parameter and the harvesting term as the control parameter, we get the existence and the stability of Hopf bifurcation at the positive constant steady state. Applying the normal form theory and the center manifold argument for partial functional differential equations, we derive an explicit formula for determining the direction and the stability of Hopf bifurcation. Finally, an optimal control problem has been considered.

Authors: Douiri Sidi Mohamed Mohamed , Elbernoussi Souad
Published: August 2019

For a given graph G = (V, E) the maximum independent set problem is to find the largest subset of pairwise nonadjacent vertices. We propose a new model which is a reformulation of the maximum independent set problem as an unconstrained quadratic binary programming, and we resolve it afterward by means of a genetic algorithm. The efficiency of the approach is confirmed by results of numerical experiments on DIMACS benchmarks.
Theory and computational study of electrophoretic ion separation and focusing in microfluidic channels
Authors: Klymenko Oleksiy V. V. , Amatore Christian , Sun Wen , Zhou Yong-Liang , Tian Zhao-Wu , Svir Irina
Published: August 2019

In this work we describe the theory and 2D simulation of ion separation and focusing in a new concept of microfluidic separation device. The principle of the method of ion focusing is classical in the sense that it consists in opposing a hydrodynamic transport ensured by the solution flow to an electrophoretic driving force so that any ionic sample results poised within the microchannel at the point where the two forces equilibrate. The originality of the concept investigated here relies on the fact that thanks to the use of an ion-conducting membrane of variable thickness in electrical contact with the channel the electrophoretic force is varied continuously all along the channel length. Similarly, changing the geometric shape of the membrane allows a facile optimization of the device separation and focusing properties.

Global dynamics of a delayed epidemic model with latency and relapse
Authors: Xu Rui
Published: August 2019

A mathematical model describing the transmission dynamics of an infectious disease with an exposed (latent) period, relapse and a saturation incidence rate is investigated. By analyzing the corresponding characteristic equations, the local stability of a disease-free equilibrium and an endemic equilibrium is established. By using suitable Lyapunov functionals and LaSalle’s invariance principle, it is proven that if the basic reproduction number is less than unity, the diseasefree equilibrium is globally asymptotically stable and therefore the disease fades out; and if the basic reproduction number is greater than unity, the endemic equilibrium is globally asymptotically stable and the disease becomes endemic.

o texto apresenta uma reflexão sobre a transexualidade: a identificação dosindivíduos com o gênero oposto ao seu nascimento. Trata-se de uma análise contextual, derivada de uma pesquisa em curso2 à luz dos aportes teóricos alteridade (BHABHA, 2005), identidade (HALL, 2004) e estigmas (GOFFMAN, 1988), atrelada a um movimento empírico que notabiliza as vozes de transexuais masculinos e femininos a partir de suas narrativas (MEDINA, 2003; ALVES, 2008). As interlocuções apontam os tratamentos midiáticos concedidos ao fenômeno sugerindo sensibilidades e subjetividades à revelia de preconceitos que relegam as minorias sexuais ao silenciamento e à invisibilidade social.

O presente texto reúne argumentos e situações que sustentam a necessidade de reflexão sobre uma “nova cidade humana”, articulada a um novo conceito de cidadania capaz de incentivar as práticas de uma comunicação proativa, em que o espaço urbano se torne sujeito de uma apropriação política e afetiva do território. É uma perspectiva a ser contemplada diante do cenário de crescente barbárie e conservadorismo, que designamos como “sociedade incivil” e consideramos sintomático da falência do projeto liberal posto em marcha por todo um conjunto de narrativas produzidas na mídia, no Estado e nas instituições.
Antonym-Synonym Classification Based on New Sub-Space Embeddings
Authors: Ali Muhammad Asif , Sun Yifang , Zhou Xiaoling , Wang Wei , Zhao Xiang
Published: August 2019

Distinguishing antonyms from synonyms is a key challenge for many NLP applications focused on the lexical-semantic relation extraction. Existing solutions relying on large-scale corpora yield low performance because of huge contextual overlap of antonym and synonym pairs. We propose a novel approach entirely based on pre-trained embeddings. We hypothesize that the pre-trained embeddings comprehend a blend of lexical-semantic information and we may distill the task-specific information using Distiller, a model proposed in this paper. Later, a classifier is trained based on features constructed from the distilled sub-spaces along with some word level features to distinguish antonyms from synonyms. Experimental results show that the proposed model outperforms existing research on antonym synonym distinction in both speed and performance.
From Independent Prediction to Reordered Prediction: Integrating Relative Position and Global Label Information to Emotion Cause Identification
Authors: Ding Zixiang , He Huihui , Zhang Mengran , Xia Rui
Published: August 2019

Emotion cause identification aims at identifying the potential causes that lead to a certain emotion expression in text. Several techniques including rule based methods and traditional machine learning methods have been proposed to address this problem based on manually designed rules and features. More recently, some deep learning methods have also been applied to this task, with the attempt to automatically capture the causal relationship of emotion and its causes embodied in the text. In this work, we find that in addition to the content of the text, there are another two kinds of information, namely relative position and global labels, that are also very important for emotion cause identification. To integrate such information, we propose a model based on the neural network architecture to encode the three elements (i.e., text content, relative position and global label), in an unified and end-to-end fashion. We introduce a relative position augmented embedding learning algorithm, and transform the task from an independent prediction problem to a reordered prediction problem, where the dynamic global label information is incorporated. Experimental results on a benchmark emotion cause dataset show that our model achieves new state-ofthe-art performance and performs significantly better than a number of competitive baselines. Further analysis shows the effectiveness of the relative position augmented embedding learning algorithm and the reordered prediction mechanism with dynamic global labels.
Explicit Interaction Model towards Text Classification
Authors: Du Cunxiao , Chen Zhaozheng , Feng Fuli , Zhu Lei , Gan Tian , Nie Liqiang
Published: August 2019

Text classification is one of the fundamental tasks in natural language processing. Recently, deep neural networks have achieved promising performance in the text classification task compared to shallow models. Despite of the significance of deep models, they ignore the fine-grained (matching signals between words and classes) classification clues since their classifications mainly rely on the text-level representations. To address this problem, we introduce the interaction mechanism to incorporate word-level matching signals into the text classification task. In particular, we design a novel framework, EXplicit interAction Model (dubbed as EXAM), equipped with the interaction mechanism. We justified the proposed approach on several benchmark datasets including both multilabel and multi-class text classification tasks. Extensive experimental results demonstrate the superiority of the proposed method. As a byproduct, we have released the codes and parameter settings to facilitate other researches.
Generating Multiple Diverse Responses for Short-Text Conversation
Authors: Gao Jun , Bi Wei , Liu Xiaojiang , Li Junhui , Shi Shuming
Published: August 2019

Neural generative models have become popular and achieved promising performance on short-text conversation tasks. They are generally trained to build a 1-to-1 mapping from the input post to its output response. However, a given post is often associated with multiple replies simultaneously in real applications. Previous research on this task mainly focuses on improving the relevance and informativeness of the top one generated response for each post. Very few works study generating multiple accurate and diverse responses for the same post. In this paper, we propose a novel response generation model, which considers a set of responses jointly and generates multiple diverse responses simultaneously. A reinforcement learning algorithm is designed to solve our model.

In neural abstractive summarization field, conventional sequence-to-sequence based models often suffer from summarizing the wrong aspect of the document with respect to the main aspect. To tackle this problem, we propose the task of reader-aware abstractive summary generation, which utilizes the reader comments to help the model produce better summary about the main aspect. Unlike traditional abstractive summarization task, reader-aware summarization confronts two main challenges: (1) Comments are informal and noisy; (2) jointly modeling the news document and the reader comments is challenging. To tackle the above challenges, we design an adversarial learning model named reader-aware summary generator (RASG), which consists of four components: (1) a sequence-to-sequence based summary generator; (2) a reader attention module capturing the reader focused aspects; (3) a supervisor modeling the semantic gap between the generated summary and reader focused aspects; (4) a goal tracker producing the goal for each generation step. The supervisor and the goal tacker are used to guide the training of our framework in an adversarial manner. Extensive experiments are conducted on our large-scale real-world text summarization dataset, and the results show that RASG achieves the stateof-the-art performance in terms of both automatic metrics and human evaluations. The experimental results also demonstrate the effectiveness of each module in our framework. We release our large-scale dataset for further research1.

Authors: Al-Toubah Taymeyah , Morse Brian , Strosberg Jonathan
Published: August 2019

Background

Patients with advanced lung neuroendocrine neoplasms (NENs) have few treatment options. Capecitabine and temozolomide have recently showed significant activity in patients with pancreatic neuroendocrine tumors (NETs), but data in lung NETs are limited.

Methods

We retrospectively reviewed the records of patients treated at a large referral center to identify patients seen between January 2008 and September 2018 with metastatic lung NENs who received treatment with capecitabine and temozolomide (CAPTEM). Patients with small cell lung cancer were excluded. The primary endpoint was overall response rate per RECIST 1.1. Secondary endpoints included progression-free survival, overall survival, and toxicity.

Results

Twenty patients were identified who received treatment with capecitabine and temozolomide. Fourteen (70%) had typical lung NETs, five had (25%) atypical carcinoids, and one (5%) had disease defined as a large-cell neuroendocrine carcinoma. Nineteen patients were evaluable for response. Six (30%) patients exhibited a best response of partial response per RECIST 1.1 criteria, 11 (55%) stable disease, and 2 (10%) progressive disease; objective response rate was 30%, and disease control rate was 85%. Eleven patients eventually progressed, only six of whom exhibited progression per RECIST 1.1 criteria. Median progression-free survival was 13 months (95% confidence interval [CI], 4.4–21.6 months). Median overall survival was 68 months (95% CI, 35.3–100.7 months). Toxicity profile was mild with mainly grade 1, expected toxicities. Six patients required dose reduction because of toxicity.

Conclusion

The CAPTEM regimen is associated with a high response rate and a relatively tolerable toxicity profile in lung NENs. This regimen warrants further exploration in a prospective clinical trial.
Tool wear assessment of turning operation by 2D finite-element simulation
Authors: Çalişkan Barış , Parlar Zeynep
Published: August 2019

Tool wear is a critical problem in industrial manufacturing. When tool wear reaches a certain value, it causes a change in tool geometry. This directly affects chip formation, cutting force, temperature distribution, machining quality and so on. Therefore, prediction of tool wear is of great importance for optimizing the cutting process. Numerical analysis is a powerful method to predicting cutting variables that are difficult to obtain by experimental method. In this paper, the effect of different tool rake angle values on tool wear rate is investigated. A two-dimensional (2D) finite-element simulation is presented for chip formation analysis considering thermal effects. Boundary conditions are defined as stationary for the workpiece and axial velocity to the tool at the cutting direction. Different models are analyzed by changing the tool geometry, and the results of the tool wear are discussed. It is shown that wear rate decreases ten times with the negative rake angle. However, increase in clearance angle causes increase in wear rate.

This paper investigates the performance of a tungsten (W)–nickel (Ni)–copper (Cu) heavy alloy with 0·5, 1·0, 1·5 and 2·0 wt% cobalt (Co) additions. The alloys are prepared through spark plasma sintering at a sintering temperature of 1400°C following a heating step of 100°C/min. The alloy with 0·5 wt% cobalt is observed to have good mechanical properties in comparison with other alloys. The density and hardness of the alloys follow a decreasing trend with an increase in cobalt addition. Subsequently, microstructural characteristics, such as contiguity, average grain size and matrix volume fraction, are measured and investigated, as they are found to affect the mechanical properties of the alloys. The average grain growth of the alloys varies around 13 µm. As the cobalt percentage is increased, tungsten–tungsten contiguity is observed to increase. The W–Ni–Cu–0·5Co alloy exhibits higher yield and tensile strength in comparison with other heavy tungsten alloys. The fracture surface analysis shows a predominantly tungsten grain cleavage fracture for 0·5 wt% cobalt alloy. The other alloys show more features of matrix interface failure and tungsten decohesion.
Structure, spectra and bioactivity of pentyl ester of chlorogenic acid: DFT study
Authors: Mishra Ashok Kumar , Tewari Satya Prakash
Published: August 2019

The pentyl ester of chlorogenic acid (C21H28O9) is reportedly a new bioactive biomaterial isolated from the leaves of the Anthocephalus chinensis plant, whose electronic structure and spectral properties are yet to be reported. In this view, the optimized geometry of the titled compound has been modeled using DFT-B3LYP/6-31+G(d,p) methods for the theoretical investigation of the spectroscopic data and electronic structure properties implementing the density functional theory (DFT) approach. The proton (1H) and carbon-13 (13C) nuclear magnetic resonance chemical shifts have also been calculated and compared with experimental values, which reveal a good agreement. A molecular docking study of the titled molecule has also been performed for the prediction of its bioactivity in which its three-dimensional shape at the equilibrium geometry has been exploited as a ligand input to interact with 1hsg and 1gcn protein receptors, which result in the final values of the free energy of binding to be −5·70 and −2·06 kcal/mol, respectively, which imply that the titled molecule may be a good natural anti-immunodeficiency and antidiabetic agent. The outcome of the present study may be useful in developing a natural drug agent and identifying the other novel structures for synthesizing the alternative drugs.
Unified thixotropic fluid model for soil liquefaction

Published: August 2019

The geotechnical earthquake engineering profession has struggled with the inherent complexity of the multiphase soil response to cyclic loading owing to the progressive nature of the generation of excess pore pressure (EPP) and degradation of soil stiffness and strength. One approach to improve understanding of the cyclic response and correlate the transition from a two-phase saturated soil to a single, fluid-phase liquefied soil is to treat the soil as a non-Newtonian viscous liquid. However, the work to date suggests that the viscous fluid model approach can only be implemented following the onset of sustained soil liquefaction. This paper presents a unified thixotropic fluid model and framework that effectively links the pre-shear soil fabric and its progressive cyclic response to the onset and maintained state of soil liquefaction. The framework treats the soil fabric as a fluid net-type structure proposed for use with thixotropic fluids, and presents the constitutive state and rate equations describing the deconstruction of the liquefiable soil fabric in response to cyclic loading. The unified framework uses physically meaningful soil parameters that can be obtained from common cyclic laboratory tests to seamlessly link the state-dependent and shear-strain-rate-dependent nature of soils to the generation of EPP, the latter of which is shown to increase in significance as EPP accumulates. The proposed thixotropic-induced excess pore pressure model should prove advantageous for use in forward modelling of the stress–strain rate response of liquefiable soil and generation of EPP.
Flexural behaviour of bamboo-reinforced wall panels with varying fly ash content

Published: August 2019

This study investigates the effect of fly ash in bamboo-reinforced mortar wall panels. The effect of fly ash with bamboo has been quantified by evaluating the material properties of bamboo, the compressive strength of mortar mixes, composite panel properties through non-destructive testing techniques and by evaluating the flexural strength of panels through two-point loading tests. Nine panels were fabricated with mortar mixes categorised into three groups based on mix proportion. Test results showed that bending cracks promote debonding of mortar layers under flexure with the addition of fly ash in wall panels due to lower bond strength development. Because of the reduced surface hardness and resilience, the first crack load and ultimate load were lowered compared to panels developed without fly ash. Debonding failure under flexure loads was observed, which leads to a reduction in flexural strength of the panels with the addition of fly ash, although significant compressive strength and cost-effectiveness was achieved.
Potential of weathered blast furnace slag for use as an addition in concrete

Published: August 2019

The paper investigates the potential for recovering granulated blast furnace slag after four to five years’ storage in a stockpile (weathered) for use as an addition in concrete. The initial research physically and chemically characterised fresh and weathered granulated slag. Thereafter, studies on ground materials in paste and mortar were carried out. The weathered granulated slag was similar to fresh slag in terms of particle size, shape and elemental composition. However, there was greater roughening of particle surfaces, with various weathering products forming. Following grinding, fresh slag comprised angular particles covering a range of sizes, while finer particles in weathered slag included fragmented reaction products. In cement paste, weathered slag gave reductions in chemically bound water. In mortar, this showed little difference in flow properties compared to fresh slag, with reductions in compressive strength and increases in porosity also noted. Further analyses suggest that, at equal Blaine fineness, weathered slag (a) is actually coarser than fresh material, affecting particle packing and giving larger capillary pores, and (b) has lower reactivity due to reduced surface area. The practical implications are examined and approaches to using weathered slag in concrete suggested.
