It Follows
Authors: Grimm Joshua
Published: February 2021

Amid a recent resurgence in horror films, David Robert Mitchell's It Follows stands out as a particularly bold entry, a horror fan's dream come true that sparked a renewed creativity. Pulling a robust 97 percent on Rotten Tomatoes, It Follows was hailed as a “teen movie you've never seen before”, a “creepy, mesmerizing exercise in minimalist horror”, “the best horror film in years”, and simply, “so damn good.” Mitchell uses a variety of approaches to reinvent genre bromides while simultaneously embracing and challenging tropes that audiences and filmmakers rely on a little too heavily. It Follows is one of the best because it is one of the most unique. This book focuses on how this film helped reinvent the rules of a horror movie, particularly along the lines of genre, style, sex, and gender.
‘I Can’t Do This’
Authors: Grimm Joshua
Published: February 2021

This chapter discusses the easy classification of David Robert Mitchell'sIt Follows that most closely falls into the slasher subgenre with its crop of teen characters. It explores the open universe concept that provides depth to It Follows's characters, resulting in audience involvement that moves beyond spectatorship. It also looks at the attribute binding the films characters Kelly, Paul, and Yara whose concern is at a level far beyond that is typically seen. The chapter highlights how the three characters in the film were quick to believe the main protagonist of the film named Jay before they saw any form of physical evidence of the entity's existence. It mentions teen romance as the most prevalent and popular subgenres that often takes the form of first dates, parties, and prom.
The Genre of Usher
Authors: van Leeuwen Evert Jan
Published: February 2021

This concluding chapter addresses the genre of Roger Corman's House of Usher (1960), which contains neither a gothic monster nor a villain. It is better to categorise House of Usher as a film belonging to a subgenre of haunted-house narratives identified as revolving around ‘tragic families and the influence of the past on the present’. Roderick and Madeline Usher are only haunted metaphorically by their knowledge of the family evil. Their ancestors do not float about the corridors in white robes, clanging their chains to shock intruders. Roderick is ‘haunted’ by the evil deeds of his ancestors because their horrific and unlawful actions have tainted the family name, and according to Roderick, have literally infected the environment and the very atmosphere he breathes. He is suffering the consequences of their crimes.
‘So, you are a Jewish nun?’
Authors: Skaff Sheila
Published: February 2021

This chapter describes how Paweł Pawlikowski's Ida opens with austere images of young novice nuns going about their lives in a convent. It analyses Ida's opening shot of an eighteen-year-old novice named Ida, who is restoring the head of a sculpture of Jesus. It also discusses Ida's striking cinematography, which shows Pawlikowski's intention to make a film of static shots or lack of camera movement that drives the viewer into a meditative state. The chapter covers several aspects of Ida's cinematography that leads the viewer into its calm, silent, relaxed world, such as the film's melancholy monochrome palette, 4:3 aspect ratio, lighting and vertical framing. It explains the meaning of Ida's vertical framing, which is a large amount of space above the characters' head in the film that signify the importance of contemplation and hint the possibility of another world above.
Introduction
Authors: Hallam Lindsay
Published: February 2021

This chapter focuses on David Lynch's film Twin Peaks: Fire Walk With Me from 1992, which is a strange prequel film to a massively popular television show that became a commercial flop. It explains Fire Walk With Me as a film that is part of a larger universe that also encompasses a recent television revival in 2017, novels, deleted scenes, DVD extras, and a huge swathe of fan-generated content apart from the original series that was aired from 1990 to 1991. It also explains Fire Walk With Me as a stand-alone film about an abused young woman and the trauma she endures. The chapter mentions how Fire Walk With Me was labelled as one of the worst films ever made in 1992 but was also proclaimed a masterpiece in 2013. It explores the Fire Walk With Me's many facets and the myriad ways that it can be felt and received.
The Devils
Authors: Arnold Darren
Published: February 2021

Undoubtedly the most notorious title in director Ken Russell's controversial filmography, The Devils (1973) caused a real furore on its initial theatrical release, only to largely disappear for many years. This book considers the film's historical context, as the timing of the first appearance of The Devils is of particular importance, its authorship and adaptation (Russell's auteur reputation aside, the screenplay is based on John Whiting's 1961 play of the same name, which was in turn based on Aldous Huxley's 1952 book The Devils of Loudun), and its generic hybridity. The book goes on to examine the themes prevalent in the film—this is the only film of Russell's which the director considered to be political—and considers the representation of gender and sexuality, gender fluidity, and how sex and religion clash to interesting and controversial effect. The book concludes by revisiting the film's censorship travails and the various versions of The Devils that have appeared on both big and small screens, and the film's legacy and influence.
Fire, Voices and Torment
Authors: Deighan Samm
Published: February 2021

This chapter focuses on Fritz Lang's seminal film M in 1931, which exists in a liminal space between social drama, crime thriller, and horror film. It explains that M follows the paedophiliac killer Hans Beckert, who is pursued by local police, distraught parents, and the criminal underworld for his horrifying and compulsive murders of Berlin's children. It also explores M's themes of systemic violence, mob justice, and urban paranoia. The chapter situates M within the developing body of twentieth-century horror films and as a progenitor of genre cinema. It also analyses M as the origin point of a filmic thread that includes Hitchcock's Shadow of a Doubt (1943) and Psycho (1960).
While the City Sleeps
Authors: Deighan Samm
Published: February 2021

This chapter scrutinizes the city in Fritz Lang's M, which suggests that the city itself is a product of modernity and is somehow responsible for madness, moral evil, and the existence of a monster like Hans Beckert. It explores how M is also a film about a community in the grip of fear and paranoia in a way that subverts a more straightforward social drama. It also describes Lang's kangaroo court that represents a divided social strata that was essentially united only by violence. The chapter suggests that the kind of violence enacted by Beckert is not only the product of a diseased mind, but it is something anyone could be capable of. It analyses M film's production, in which Lang made use of the city of Berlin in a sort of proto-neorealist sense and employed non-professional actors from among the city's criminal class.
Dune
Authors: McCrea Christian
Published: February 2021

David Lynch's Dune (1984) is the film that science fiction — and the director's most ardent fans — can neither forgive nor forget. Frank Herbert's original 1965 novel built a meticulous universe of dark majesty and justice, as wild-eyed freedom fighters and relentless authoritarians all struggled for control of the desert planet Arrakis and its mystical, life-extending “spice.” After several attempts to produce a film, Italian movie mogul Dino De Laurentiis and his producer daughter Raffaella would enlist David Lynch, whose Eraserhead (1977) and The Elephant Man (1980) had already marked him out as a visionary director. What emerges out of their strange, long process is a deeply unique vision of the distant future; an eclectic bazaar of wood-turned spaceship interiors, spitting tyrants, and dream montages. Lynch's film was “steeped in an ancient primordial nastiness that has nothing to do with the sci-fi film as we currently know it,” as Village Voice critic J. Hoberman put it — only with time becoming a cult classic. This book is the first long-form critical study of the film; it delves into the relationship with the novel, the rapidly changing context of early 1980s science fiction, and takes a close look at Lynch's attempt to breathe sincerity and mysticism into a blockbuster movie format that was shifting radically around him.
A Dream Unfolds: Before Dune
Authors: McCrea Christian
Published: February 2021

This chapter maps the science fiction milieu, which includes David Lynch's Dune. It explains how science-fiction cinema had been bursting into new life throughout the late 1970s and early 1980s. It also mentions the influence of Frank Herbert's original novel of Dune on stories of interstellar science fiction, such as the first Star Wars trilogy. The chapter discusses Herbert's approach to fiction and personal biography that provide some of the seeds of what the film version of Dune would become. Since Dune occurs in the shadow of Star Wars, it also provides context for the production and consumption of science-fiction film in the years between the releases of the two movies.
The Golden Path
Authors: McCrea Christian
Published: February 2021

This chapter examines the unexpected longevity of David Lynch's Dune, a film that was for many deemed dead on arrival. It assesses Dune's lasting legacy from absurd tie-in merchandise to incredible comic translations to the videogames that changed game history in significant ways. It also emphasizes how Lynch's Dune demands the attention like no other film as it unfolds ceremonially into a dream already in motion. The chapter discusses how Dune remains a focused, singular vision that startles and delights in its difference in the history of science-fiction cinema. It reviews every dashed hope and upraised hand of anguish that believed Dune's literary universe could be adapted if given the right conditions. It talks about how Dune represents so much to so many in search of parables of failure, promise, corrupt systems and ineffable creative possibility.
Conversations with The Mummy: Critical Reactions
Authors: Sutherland Doris V.
Published: February 2021

This chapter describes the critical reception of The Mummy (1932). When the film was screened, professional film critics were intrigued by the central figure of Boris Karloff, the actor who had been transformed into a living mummy. The Los Angeles Times even offered a prescient take that foresaw Karloff's future place in the film pantheon. As for the film itself, however, the critical reception was more lukewarm. Critics who had grown tired of horror cinema found little in The Mummy to change their opinions. The chapter then looks at re-evaluations and later evaluations of the film. Critics continue to find weaknesses, but they also continue to find rewarding new ways of approaching The Mummy. On the whole, The Mummy has managed to stand firm despite early critical indifference and subsequent changes in audience tastes. The film's position as the start of a subgenre has ensured that The Mummy retains immortality as a popular culture artefact.
Coda: Gilliam’s Art of the Possible
Authors: Kord Susanne
Published: February 2021

This chapter talks about getting caught in a loop as one of Terry Gilliam's greatest fears, much like the one that characterises the 12 Monkeys series, which has become derivative and repetitive. It explains why Gilliam famously refused to read Orwell's 1984 before making the film Brazil, and why he refused to see La Jetée before making 12 Monkeys. It also discusses anticipated memory, recollections from the future, and pre-emptive foretastes of the as-yet unknown. The chapter examines four-dimensional creativity enabled by two basic steps: rejection of linearity and partiality for the possible over the real. It looks at principal differences between 12 Monkeys the film and 12 Monkeys the show.
The Resistance
Authors: Dinello Dan
Published: February 2021

This chapter talks about the underground cadre of militant freedom fighters called the Fishes as the mostconspicuous organized resistance group portrayed in Alfonso Cuarón's Children of Men. It discusses how Children of Men disparages the Fishes and their mirage of revolution as the film condemns the fascistic actions of Britain — a modern democratic state turned savage. It also analyses how Children of Men rejects the Fishes as a treacherous goon squad, even though their political goal — the liberation of oppressed migrants — is worthy. The chapter examines Children of Men's main protagonist Theo Faron, who resembles the central character Meursault in Albert Camus'most famous novel The Stranger (1942). It mentions how no organized political groups are championed in Children of Men except for the vaguely defined Human Project, noting that the only source of hope for the future is Theo.
Eccentric Early Migration of Neptune
Authors: Nesvorný David
Published: February 2021

The dynamical structure of the Kuiper Belt can be used as a clue to the formation and evolution of the solar system, planetary systems in general, and Neptune’s early orbital history in particular. The problem is best addressed by forward modeling where different initial conditions and Neptune’s orbital evolutions are tested, and the model predictions are compared to orbits of known Kuiper Belt objects (KBOs). It has previously been established that Neptune radially migrated, by gravitationally interacting with an outer disk of planetesimals, from the original radial distance r ≲ 25 au to its current orbit at 30 au. Here we show that the migration models with a very low orbital eccentricity of Neptune (e
N ≲ 0.03) do not explain KBOs with semimajor axes 50 < a < 60 au, perihelion distances q > 35 au, and inclinations i < 10°. If e
N ≲ 0.03 at all times, the Kozai cycles control the implantation process and the orbits with q > 35 au end up having, due to the angular momentum’s z-component conservation, i > 10°. Better results are obtained when Neptune’s eccentricity is excited to e
N ≃ 0.1 and subsequently damped by dynamical friction. The low-e and low-i orbits at 50–60 au are produced in this model when KBOs are lifted from the scattered disk by secular cycles—mainly the apsidal resonance ν
8—near various mean motion resonances. These results give support to a (mild) dynamical instability that presumably excited the orbits of giant planets during Neptune’s early migration.
Constraining the Positive Ion Composition in Saturn’s Lower Ionosphere with the Effective Recombination Coefficient
Authors: Dreyer Joshua , Vigren Erik , Morooka Michiko , Wahlund Jan-Erik , Buchert Stephan C. , Johansson Fredrik L. , Waite Jack Hunter
Published: February 2021

The present study combines Radio and Plasma Wave Science/Langmuir Probe and Ion and Neutral Mass Spectrometer data from Cassini’s last four orbits into Saturn’s lower ionosphere to constrain the effective recombination coefficient α
300 from measured number densities and electron temperatures at a reference electron temperature of 300 K. Previous studies have shown an influx of ring material causes a state of electron depletion due to grain charging, which will subsequently affect the ionospheric chemistry. The requirement to take grain charging into account limits the derivation of α
300 to upper limits. Assuming photochemical equilibrium and using an established method to calculate the electron production rate, we derive upper limits for α
300 of ≲ 3 × 10−7 cm3 s−1 for altitudes below 2000 km. This suggests that Saturn’s ionospheric positive ions are dominated by species with low recombination rate coefficients like HCO+. An ionosphere dominated by water group ions or complex hydrocarbons, as previously suggested, is incompatible with this result, as these species have recombination rate coefficients > 5 × 10−7 cm3 s−1 at an electron temperature of 300 K.

Fundamental scientific objectives concerning the surface and subsurface material and dynamics of the Moon are the drivers for the use and advancement of penetrators, which emplace a suite of scientific instruments by impact into a planetary surface, typically at velocities of dozens to hundreds of meters per second. Small lunar penetrators are poised to become a valuable new tool for lunar science and exploration during the next decade. These low-cost ballistic probes can be deployed in large numbers from orbit, or from descending robotic or crewed vehicles, in order to explore and characterize the diversity of extreme lunar shallow subsurface environments. In this paper, we describe the general overview of penetrator objectives, potential instrumentation, and how these would benefit the advancement of lunar science at various extreme environments.
On a noteworthy habitat type in the savannas of Central Cuba and a remarkable new species of Elytraria (Acanthaceae)
Authors: Greuter Werner , Rankin Rodríguez Rosa
Published: February 2021

A peculiar habitat type found in the savannas of Central Cuba, Villa Clara province, and characterized by the presence of a surface gravel layer of “perdigones”, an assemblage of small ferralitic concretions, upon the “mocarrero” soil prevailing in the area, is described. On sterile gravel patches only one species grows: Elytraria serpens, a new species decribed and named here. It is noteworthy for possessing long and wide creeping, stoloniform subterranean peduncles with apical gemmae developing into rooting leaf rosettes enabling vegetative propagation. The new species is close to E. shaferi and considered to derive from the latter by adaptive evolution enabling it to survive in its hostile habitat, sheltered from the competition of other plant species. Small soil insects, e.g. ants, are believed to act as pollinators.
Effects of Single or Combined Supplementation of Probiotics and Zinc on Histological Features of Ileum, Glucagon Like Peptide-1 and Ghrelin Levels in Malnourished Rats
Authors: Purnasari Perez Wahyu , Nasihun Taufiqurrachman , Zulaikhah Siti Thomas
Published: March 2021

Introduction: Malnutrition causes small intestinal atrophy leading to impaired nutrient absorption, zinc deficiency, and intestinal mi-crobiota imbalance affecting appetite. Zinc-only supplementation programs have been shown to be ineffective in reducing the national prevalence of malnutrition.

Aim: The aim of this study was to assess the effects of probiotics and zinc in single or combined supplementation on the histological features of ileum and appetite regulating hormone in malnourished rats.

Materials and methods: This study included 25 rats aged 8 weeks (weight 150-200 g) divided into 5 groups. Group A served as normal receiving standard diet, group B served as malnourished receiving low calorie diet. Groups C, D, E were pretreated with calo-rie restriction for 14 days to induce malnutrition. The treatment was given for 14 days. Group C was treated with probiotics and zinc combination, group D was treated with probiotics, group E - with zinc. All treatment groups received standard diet at the same time. Ileum sample was taken and subjected to histological preparations using hematoxylin-eosin staining to evaluate villi height and mucosal thickness, blood sample was taken for GLP-1 and ghrelin levels evaluation using ELISA methods.

Results: Probiotics and zinc co-supplementation significantly increased villi height and zinc supplementation significantly increased mucosal thickness compared to malnourished rats. GLP-1 levels were significantly increased and ghrelin level was reduced with single or combined supplementation of probiotics and zinc.

Conclusions: Low-calorie feed administered within 14 days successfully changed the profiles of small intestinal histology in rats. Either single or combined administration of probiotics and zinc develop the histological features of ileum and appetite in the malnou- rished rats. 
Qu’est-ce que guérir du cancer veut dire ?
Authors: Aubry Régis
Published: February 2021

Guérir n’est pas le retour à la situation antérieure. Être malade du cancer confronte la personne à l’idée et à la peur de la mort. L’expérience de la maladie est l’expérience de la résilience et de la transcendance. La guérison est aussi paradoxalement une perte, une rupture d’avec un temps dense et le retour à soi : se retrouver seul et différent n’est pas simple. Enfin, il n’est pas rare que la guérison s’accompagne de séquelles visibles ou invisibles, comme la fatigue chronique. C’est pourquoi les soins et l’accompagnement ne doivent pas forcément s’arrêter lorsque la maladie est guérie.

Overview of Nano-Strategies for Combating Cancer
Authors: Janapati Yasodha Krishna , Junapudi Sunil , Dachani Sudharshan Reddy
Published: February 2021

Cancer is one of the prime rationales for mortality in humanity and remains a difficult disease to treat. Contemporary problems allied with conventional cancer chemotherapies embrace the insolubility of drugs in an aqueous medium, delivery of sub-therapeutic doses to target cells, lack of bioavailability, and most importantly, non-specific toxicity to normal tissues. Recent advances in nanotechnology investigation tackle potential solutions to these riddles. However, there are challenges regarding targeting specific sites, tracking the delivery system and control over the release of the drug to the target site. The nanodevices are 100 to 1000 times smaller than cells in humans; their size is comparable to the enzymes, the receptors. This enables them to have a large surface area and ability to interact with biomolecules on both the surface and inside cells. Nanomedicines between 8-100 nm have an enhanced permeability and retention (EPR) effect, which make these medicines to target passively the solid tumours.
Current Therapies and Future Prospects
Authors: K. Muddukrishnaiah
Published: February 2021

Due to drug resistance, lack of cancer cell selectivity, and solubility, conventional cancer treatments lose their therapeutic uses, and as such, new therapeutic agents need to be developed. Nanomaterials and peptides are increasingly being used in the fields of cancer diagnosis, biomarker discovery due to their therapeutic values and novel way of targeting and curing the disease. Synergism among the peptide-conjugated nanoparticles is an exhilarating group of materials, not only sharing the benefits of conventional nanomedicine, but also possessing the unique properties of excellent biocompatibility, biodegradability, versatile sensitivity, specific biological purpose, and synthetic feasibility. These virtues inspired by the scientists and have taken advantage in the peptide-conjugated nano drugs for the accurate delivery of drugs reliably to the site of the lesion. This chapter offers a summary of emerging technologies that have recently been developed in the broad field of peptide-conjugated nanoparticles and offers guidance for targeted drug delivery and cancer therapy.

Published: February 2021

The development and advancement of nanotechnology has led to widespread use of nanomaterials (NMs) in a wide variety of fields, including the environment, agriculture, biomedicine, industry, and human health. Nanomaterials may interfere with biological systems due to their smaller size and increased surface area ratios in terms of volume which may raise unanticipated toxicological apprehensions. The minute nature of the particles may cross biological margins and induce toxicity in vital organs like the human brain and placenta. Moreover, environmental exposures to NMs are inevitable, which have become crucial parts of our daily routine lives and consequently, search for the nanotoxicity is gaining attention to lessen or get rid of the toxic impacts of the NMs. The safety concerns and risk assessment of NMs have been raised significantly in research community circles, industries, and regulatory bodies. The information in the concerned section, obtained from current literature and toxicological effects of NMs research are assorted.
Masters of Imagination
Authors: van Till Jaap
Published: February 2021

This chapter is about some observations of the social and economic impact of ICT and ICT digital infrastructures and more specifically what users do with processing and telecommunication power tools. Network architects should be aware of those. Computer systems are no longer neutral tools, but they influence companies, public policies for control and institutions, and civil society cooperatives. Even the internet architecture board (IAB) has issued a directive about these effects. Electronic and network surveillance of users and what they do is growing with effects on elections. ICT is at the core of several large-scale transitions identified in this chapter. Groups of people who are immune to social media propaganda and alternative truth are discovered. And the chapter is rounded off with a hopeful vision about constructive value creation in cooperatives and science teams, making use of liberty of though and diversity of backgrounds. Making swarms and micro grids makes society alive again. Social super resolution is an interesting direction to pursue together.

Published: February 2021

The concept of augmented reality (AR) is a topic of increasing importance for the future of marketing. Research, especially on AR in mobile devices, is still in its infancy; therefore, this study explored the user motivations to employ mobile augmented reality applications against the hindrance of perceived risks and tried to understand user acceptance and willingness to use this technology and possible marketing-related outcomes. In-depth interviews were carried on with 16 participants as well as three mini focus group interviews with 12 participants. The underlying theories utilized were the technology acceptance model (TAM) and the uses and gratifications (U&G). The results showed that entertainment, obtaining information, experiential qualities, socialization, and personal motivations acted as gratifications in the adoption of AR applications, which exerted positive influence on brand interest, image, and purchase intention of the users.
Results of the Research in the Comparison and Analysis of Historical Artifacts' Photographic Images Catalogued in Online Databases
Authors: Tedaldi Marco
Published: February 2021

In the field of archaeology, when a discovery is made, the comparison of images is often used to catalogue a find and give it an interpretation. The image on an exhibit is always subject to analysis, comparisons, graphic reconstructions, which can define it, classify it, and most of all, understand it as a whole. The problem arises when the discovered find proposes a completely new and unpublished image. It therefore requires an in-depth study in all its elements. Photographic images, online databases, and archive collections of museums provide some valid help for solutions or interpretations; and the theories that come out of this comparison can then shed light on the meaning of an image present in a find, when there is no direct confirmation.

Authors: Namane Sarra , Ghoualmi Nassira , Kaiiali Mustafa
Published: February 2021

Access control mechanisms are the way to guarantee secure access to grid resources. Recent research works were focused on how to improve the representation of the resources' security policies for faster decisions making. PCM, HCM, GAG, and WGAG are all different ways to represent these security policies. This paper presents an enhancement to WGAG, the action-weighted grid authorization graph (Action-WGAG). A security policy-parser (SP-Parser) has been developed to implement the Action-WGAG. The evaluation results of the proposed model showed that it assures a smaller number of security rule checking in some cases and a reduction of the answer time to an access control request.

Published: February 2021

Excellent osteoconductivity and resorbability achieved when porous bioceramics have highsurface area that providing fast bone ingrowth. Porous samples were fabricated by using biphasic calcium phosphate BCP (achieved from HA heat treated at 850 oC) with 10 and 20 wt% of ovalbumin binder powder and mixture of carrot fibers and ovalbumin powders (1:1) then dried at 60oC and fired at 1300 oC. Structural, physical and mechanical properties of the prepared porous bioceramic were determined involved X-ray diffraction, Fourier transform infrared spectroscopy FTIR, apparent porosity, water absorption, apparent solid density and compressive strength. The results of X-ray and FTIR showed that the heat treatment of HA was succeeded in forming biphasic calcium phosphate. The apparent porosity values increased with increasing of the binder and carrot fibers content and the growths density of bacteria on bioceramics are less than natural bone. The effect of pathogenic bacteria (Pseudomonas & Staphylococcus) that cause pollution on porous calcium phosphate and natural bone (Albino mice) has been studied.
The Biomechanics of the Fibrocystic Breasts at Finite Compressive Deformation
Authors: Akano Tochukwu Akano , Fakinlede Omotayo Abayomi , Nwoye Ephraim
Published: February 2021

The deformation of the human breast, especially that of the female, under variable pressure conditions, has been a recent focus for researchers, both in the computational biomechanics, computational biology and the health sector. When the deformation of the breast is large, it hampers suitable cyst tracing as a mammographic biopsy precontrive data. Finite element methods (FEM) has been instrumental in the currently studied practices to trail nodules dislocation. However, the effect of breast material constitution, especially that of a fibrocystic composition, on the biomechanical response of these nodules has gained less attention. The present study is aimed at developing a finite element fibrocystic breast model within the frame of biosolid mechanics and material hyperelasticity to model the breast deformation at finite strain. The geometry of a healthy stress‐free breast is modelled from a magnetic resonance image (MRI) using tissues deformations measurements and solid modelling technology. Results show that the incompressible Neo-Hookean and Mooney-Rivlin constitutive models can approximate large deformation of a stressed breast. In addition to the areola (i.e. nipple base), the surrounding area of the cyst together with its interface with the breast tissue is the maximum stressed region when the breast is subjected to compressive pressure. This effect can lead to an internal tear of the breast that could degenerate to malignant tissue.
Green Synthesis of Nanoscale Zero-Valent Iron/Activated Carbon Composites and their Application for Copper and Chromium Removal from Aqueous Solutions
Authors: Afroosheh Fatemeh , Bakhtiari Somayeh , Shahrashoub Meysam , Ebrahimi Majid
Published: February 2021

In this study, nanoscale zero-valent iron (nZVI) particles and their composites with powdered activated carbon (nZVI-PAC) and granular activated carbon (nZVI-GAC) were successfully synthesized via a low-cost green approach with the use of green tea extract. The adsorbents were then used to remove Cr and Cu from aqueous solutions, and their adsorption results were fitted with the Freundlich and Langmuir models. The synthesized adsorbents were characterized using XRD, FTIR, and FESEM techniques. The typical peak of Fe0 was detected in the XRD patterns of prepared samples, but the presence of organic compounds in green tea extract weakened related peak. The FESEM characterization demonstrated that the nZVI spherical particles had a chain-like structure and ranging in size from 10 to 50nm. The presence of polyphenols peak in the FTIR spectra revealed that the green tea extract was responsible for the reduction of the Fe2+ to Fe0. The maximum adsorbed amount of Cr and Cu was found to be 5.68 and 6.48 mg/g, which was achieved by nZVI-PAC and nZVI, respectively. The nZVI-PAC and nZVI also showed a higher removal efficiency for Cu and Cr by 62% and 94% for an initial concentration of 100 mg/L, respectively. The results showed that nZVI, nZVI-PAC, and nZVI-GAC could be promising and eco-friendly adsorbents for Cr and Cu removal from aqueous solutions.

A novel redox couple of metallic nickel (Ni) catalyst can become a great candidate of non-enzymatic detection. By taking advantage of fast electron transfer, Ni redox couples can be tailored as pseudo-enzyme in urea measurement. In this study, Ni catalyst on nitrogen doped carbon (Ni-NC) was synthesized and characterized morphological, elemental, and electrocatalytic properties in comparison to different configuration of pure nickel (Ni), Ni with carbon (Ni-C), and bare carbon electrode, assessed by cyclic voltammetry and differential pulse voltammetry. By examining various Ni redox couples in rapid electron transfer process, the prominent anodic and cathodic peaks of Ni2+/Ni3+ were applicable to detect urea in the detection range of 1-20 mM, with an excellent sensitivity and relative standard deviation of 1.634 μA.mM-1 (R2 of 0.989) and 4.89%, respectively. Therefore, Ni-NC can find practical applications for material sensing device toward non-enzymatic urea measurement.

In this study, we modified polypropylene (PP) by using melt-blending hollow silica (HSiO2) with it and to form HSiO2/PP composites. The composites were characterized by mechanical properties, X-ray diffraction (XRD) and fourier transform infrared spectroscopy (FTIR). In order to investigate the effect of nanofiller to the barrier property of water vapor, the water vapor transmission rate of PP and HSiO2/PP composites has been tested. The study found that the addition of HSiO2 did not change the crystal structure of the matrix material and there was no chemical reaction. However, the tensile strength of the composite is improved, and the water vapor barrier performance were also improved. When the content of HSiO2 is 0.9%, the tensile strength of the composite is the highest and the water vapor resistance is the best.

The manufacturing industries for automotive parts aim to develop technologies for reducing vehicle weight in order to decrease fuel consumption. However, passive safety function for drivers and passengers must not be impaired or should be even improved. Therefore, advanced high strength steel sheet plays more and more important role in designing automotive components. Nowadays, prediction of formability for sheet metal stamping has high capability more than the past. The major challenge is springback prediction. Moreover, it assists in the tooling design to correctly compensate for springback. Especially in automotive production, springback effects have been generally exhibited distinct after forming process of the high strength steel sheets. The springback effect occurred in the deformed state of metal parts must be taken into account by designing any sheet metal panels. Then, the purpose of the present research is to investigate the springback phenomenon of an automotive part named Reinforcement Rocker RL made from an advanced high strength steel grade JAC780Y, after stamping. In addition, the tools design has been carried out. Finite Element (FE) program known as DYNAFORM (based on LS-DYNA solver), has been applied to analyze and improve the springback effect on such forming part. An anisotropic material model according to type 36 (MAT_036 3-PARAMETER_BARAT) was applied. The results obtained from simulations were compared with required parts in each section. Then, the die surface from compensation in 2nd step forming was modified to use. Finally, the simulation part was verified with the real stamping part. It was found that the finite element simulation showed high capability for prediction and compensation of springback in high strength steel sheets forming.

Published: February 2021

Metal oxide semiconductor has been widely used for breath analyzer applications. In this work, Acetone gas is the target gas as it an important breath marker for diabetes disease. Among the different p-type metal oxide nanostructures, Nickel oxide nanospheres are used as the sensing material as it is a promising candidate for Acetone sensing. The variation of resistance of the sensing material with the concentration of the target gas was analyzed. As Acetone is a reducing gas, the resistance of the sensing layer was found to increase when the sensing layer was exposed to the target gas. The simulation was done using COMSOL Multiphysics.

Published: February 2021

Background: Previously developed prediction models for type 2 diabetes mellitus (T2DM) have limited performance. We developed a deep learning (DL) based model using a cohort representative of the Korean population.Methods: This study was conducted on the basis of the National Health Insurance Service-Health Screening (NHIS-HEALS) cohort of Korea. Overall, 335,302 subjects without T2DM at baseline were included. We developed the model based on 80% of the subjects, and verified the power in the remainder. Predictive models for T2DM were constructed using the recurrent neural network long short-term memory (RNN-LSTM) network and the Cox longitudinal summary model. The performance of both models over a 10-year period was compared using a time dependent area under the curve.Results: During a mean follow-up of 10.4±1.7 years, the mean frequency of periodic health check-ups was 2.9±1.0 per subject. During the observation period, T2DM was newly observed in 8.7% of the subjects. The annual performance of the model created using the RNN-LSTM network was superior to that of the Cox model, and the risk factors for T2DM, derived using the two models were similar; however, certain results differed.Conclusion: The DL-based T2DM prediction model, constructed using a cohort representative of the population, performs better than the conventional model. After pilot tests, this model will be provided to all Korean national health screening recipients in the future.

Maquiavelo y la perfidia de Venecia
Authors: García Jurado Roberto
Published: February 2021

Maquiavelo no sentía simpatía ni agrado por Venecia. A pesar de que sólo Venecia y Florencia, su patria, eran los dos grandes estados italianos que a principios del siglo XVI habían conservado gobiernos republicanos, lo que hipotéticamente debía hermanarlas, entre ambas repúblicas había más competencia que cooperación, lo cual se reflejaba fielmente en el pensamiento y opiniones de Maquiavelo. Además, Venecia constituía un modelo de república aristocrática que contrastaba con el modelo de república democrática de la antigua Roma que tanto admiraba Maquiavelo, lo cual acentuaba su desagrado. Más aún, el gobierno republicano de Florencia de 1494-1512 al que sirvió Maquiavelo, trató de reformarse a imagen y semejanza de las instituciones políticas venecianas, en lo cual no tuvo mucho éxito. De este modo, el ejemplo de Venecia suscitó una serie de reflexiones y opiniones de Maquiavelo sobre el gobierno republicano que son dignas de análisis y que constituyen la materia de este escrito.

A Qualitative Study of the Achievement Goals of Recreational Exercise Participants
Authors: Rogers Helen , Morris Tony , Moore Melissa
Published: February 2021

Physical inactivity is a major risk factor for many of today’s leading causes of ill health. In-order to increase physical activity (PA) participation and information about why people engage in PA is needed. We interviewed 11 recreational exercise participants to examine their goals for participating in recreation al exercise. Our results revealed 13 first-order themes, which we reduced to seven second-order themes (personal comparison, extrinsic rewards, social, physical condition, psychological condition, mastery, and enjoyment), and two general dimensions (intrinsic and extrinsic goals). We argue that self- determination theory (SDT) of motivation provides a strong foundation for understanding the goals and motives for recreational exercise. Also, future research should aim to develop a more comprehensive measure of motivation in recreational exercise and sport contexts.
Characteristics of Home: Perspectives of Women Who Are Homeless
Authors: Walsh Christine , Rutherford Gayle , Kuzmak Natasha
Published: February 2021

We employed participatory, community-based research methods to explore the perceptions of home among women who are homeless. Twenty women engaged in one or more techniques including qualitative interviews, digital story telling, creative writing, photovoice, and design charrette to characterize their perceptions of home. Analysis of the data revealed themes related to the physical, affective, and external environment. By understanding how participants perceive home and the qualities they deem necessary for home, we can begin to construct home from both a service and design perspective that meets womens needs for stable, safe housing and home, and also gain a better understanding of what is needed to assist women in exiting homelessness and building more sustainable futures for themselves and their families.
