Excavating the Future
Authors: Malley Shawn
Published: January 2020

Well-known in popular culture for tomb-raiding and mummy-wrangling, the archaeologist is also a rich though often unacknowledged figure for constructing ‘strange new worlds’ from ‘strange old worlds’ in science fiction. But more than a well-spring for scenarios, SF’s archaeological imaginary is also a hermeneutic tool for excavating the ideological motivations of digging up the past buried in the future. A cultural study of an array of popular though critically neglected North American SF film and television texts–spanning the gamut of telefilms, pseudo-documentaries, teen serial drama and Hollywood blockbusters–Excavating the Future treats archaeology as a trope for exploring the popular archaeological imagination and the uses to which it is being put by the U.S. state and its adversaries. By treating SF texts as documents of archaeological experience circulating within and between scientific and popular culture communities and media, Excavating the Future develops critical strategies for analyzing SF film and television’s critical and adaptive responses to contemporary geopolitical concerns about the war on terror, homeland security, the invasion and reconstruction of Iraq, and the ongoing fight against ISIS.
Introduction
Authors: Malley Shawn
Published: January 2020

The introductory chapter establishes relationships between archaeology as a trope within SF film and television and as a cultural site from which to investigate the medium’s critical engagement with post 9/11 geopolitics. Arguing that the imagination of the future is indelibly overrun by the past, scholars like Fredric Jameson, Gary Wolfe and Carl Freeman contend that SF is a historicist genre that exposes its master fantasy of progress to the kinds of real and symbolic assaults on Western global power represented by 9/11. The introduction contends that SF film and television offer resistant readings of the ways mediatized weapons of retaliation on the West circulate within popular culture as potent images of threat and fear that have leant Western governments extraordinary powers of surveillance and control over its citizens and the world in the name of freedom and security. The introduction historicises the cinematic and televisual response to 9/11 and its aftermath by looking back to Stanley Kubrick’s 2001: A Space Odyssey (1968), a film that speaks obliquely to the terrible events of the year it imagines, in which the cinematics of terror have been naturalized within the SF cinematic imagination.
Transformers 2: Revenge of the Fallen
Authors: Malley Shawn
Published: January 2020

This chapter examines the representation of archaeology in the action/adventure cinematics of Michael Bay's Transformers 2: Revenge of the Fallen (2007), a film predicated on hidden relics transforming explosively into action. The film's diegetic environment—which features a hunt for a lost relic that happens to be the key to an ancient doomsday device secreted away inside the Great Pyramid at Giza—is analogous to the its specific geographical and historical setting. The film is "Babylonian" in that it invokes Orientalist imagery as an almost inevitable generic necessity within SF action/adventure cinema. The chapter argues specifically that the military, archaeological and geopolitical motifs of the film are most clearly and coherently aligned in the framing and shot-making techniques of the action sequences themselves. By figuratively compressing time into literally compressed spaces (here principal photography at Petra, Giza and Luxor is collapsed into a single location), the set/setting is a chronotopic threshold that transforms antiquity into a battle ground for military technocratic modernity.
Smallville
Authors: Malley Shawn
Published: January 2020

For 10 seasons Smallville (2001-2011) remodelled Superman for audiences growing up with Clark Kent in an age perhaps uniquely defined by insecurity. Clark's struggles to understand what the audience infers is his pre-determined destiny are shaped within social realities very different from those of his comic book progenitor's. The show very smartly establishes tensions between good and evil not in terms of moral benchmarks but through complex exercises of power. Archaeology is an important vehicle for Smallville's revitalization of the Superman mythos. As a decade-long excavation and reinterpretation the Kryptonian's coming of age as the guardian par excellence of national and global security, a mysterious blend of artefacts, expeditions and ancient aliens are crucial sources of contestation and education for the young superhero. Through archaeological reference, education and exploration, the show sets up a flexible framework for responding to current crises in terms that resist the binaries under which such antagonisms are rendered in so much of the popular rhetoric circulating in the American geopolitical imaginary.
William Gilbert and Esoteric Romanticism
Authors: Cheshire Paul
Published: January 2020

William Gilbert, poet, theosophist and astrologer, published The Hurricane: A Theosophical and Western Eclogue in Bristol in 1796, while he was on intimate terms with key members of Bristol literary culture: Coleridge published an extract from The Hurricane in his radical periodical The Watchman; Robert Southey wrote of the poem’s ‘passages of exquisite Beauty’; and William Wordsworth praised and quoted a long passage from Gilbert’s poem in The Excursion. The Hurricane is a copiously annotated 450 line blank verse visionary poem set on the island of Antigua where, in 1763, Gilbert was born into a slave-owning Methodist family. The poem can be grouped with other apocalyptic poems of the 1790s—Blake’s 'Continental Prophecies', Coleridge's 'Religious Musings', Southey's Joan of Arc—all of which gave a spiritual interpretation to the dramatic political upheavals of their time. William Gilbert and Esoteric Romanticism presents the untold story of Gilbert’s progress from the radical occultist circles of 1790s London to his engagement with the first generation Romantics in Bristol. At the heart of the book is the first modern edition of The Hurricane, fully annotated to reveal the esoteric metaphysics at its core, followed by close interpretative analysis of this strange elusive poem.
Esoteric Romanticism
Authors: Cheshire Paul
Published: January 2020

This chapter views two particular forms of English Romanticism from the perspective of the history of esotericism, as defined by Antoine Faivre. First, Gilbert’s portrayal of Nature in his Bristol poems shows his receptivity to the ‘One Life’ vision propounded by the West Country Romantics. If, as this chapter argues, passages from poems such as ‘Tintern Abbey’ are records of visionary experience, their underlying philosophy belongs within the history of esotericism, which – according to Faivre – prioritises imagination as an ‘organ of the soul’. Second, Coleridge’s unpublished ‘compass of nature’ diagrams from 1814 onwards combine the traditional elements of Gilbert’s Hermetic diagrams with the newly discovered scientific elements carbon, hydrogen, oxygen and nitrogen. After Coleridge (and the German Nature philosophers who influenced him) the attempt to integrate scientific discoveries and esoteric wisdom has come to be viewed as a subcultural activity.
Introduction
Authors: Holohan Carole
Published: January 2020

The introduction situates the study within the existing international and national historiographies of the postwar period, the sixties and youth. It indicates the way in which the social category of youth will be used as a lens through which social change and modernization in the Republic of Ireland can be more clearly understood.
Conclusion
Authors: Caslin Samantha
Published: January 2020

While historians have examined how prostitution and promiscuity were frequently conflated by social purists and philanthropists in the late Victorian period and early twentieth century, this book examines the persistence of these ideas well into the latter half of the twentieth century. The notion that the respectable, young, working-class woman could be distinguished from the supposedly disreputable and corrupting prostitute produced a highly gendered understanding of urban space. Working-class women, and especially immigrant working-class women, were monitored for signs of apparent moral weakness. Moreover, even as social purity organisations went into decline in the post-war years, their ideas persisted in legislative efforts to control prostitution. Women who worked as prostitutes were increasingly regulated and pushed out of sight into less safe working spaces. As such, it is argued here that the law increasingly mirrored the sort of social purity thinking which considered prostitution to be a form of moral contagion which needed to be eradicated.
Decadent Modernity
Authors: Coletta Michela
Published: January 2020

How did Latin Americans represent their own countries as modern? By treating modernity as a ubiquitous category in which ideas of progress and decadence are far from being mutually exclusive, this book explores how different groups of intellectuals, between the late nineteenth and the early twentieth century, drew from European sociological and medical theories to produce a series of cultural representations based on notions of degeneration. Through a comparative analysis of three country case studies − Argentina, Uruguay and Chile − the book investigates four themes that were central to definitions of Latin American modernity at the turn of the century: race and the nation, the search for the autochthonous, education, and aesthetic values. It takes a transnational approach to show how civilisational constructs were adopted and adapted in a postcolonial context where cultural modernism foreshadowed economic modernisation. In doing this, this work sheds new light on the complex discursive negotiations through which the idea of ‘Latin America’ became gradually established in the region.
Poetry & Barthes
Authors: Gardner Calum
Published: January 2020

This book is the first study of how the work of Roland Barthes, one of the most influential literary theorists of the twentieth century, came to be understood by poets working in English. Beginning with the work of the Scottish poet Veronica Forrest-Thomson in the 1970s, it traces Barthes through North American ‘Language writing’, the journals and little magazines of the period, 1980s writers responses to Barthes’ work on love, and finally writers who, for a variety of reasons, rejected Barthes’ theoretical interventions. In doing so, it offers a picture of how poets’ understanding of their own projects develops during this period as well as a unique perspective on Barthes and his reception, positive and negative, in English-language poetry communities.
Rejections of Barthes
Authors: Gardner Calum
Published: January 2020

The methodology of the book means that writers’ engagement with Barthes is what is studied, but this risks erasing writers who shy away from him. This chapter considers why some poets, particularly those who are people of colour and/or queer, reject Barthes aesthetically and politically. This issue is positioned in relationship to contemporary discussions of avant-garde poetry and whiteness, and these concerns are illustrated with a more in-depth reading of the work of John Yau. This is followed by a discussion of queer objections to the Barthes of language poetry and a consideration of his work in the context of the New Narrative. The chapter concludes by considering why Kathy Acker rejects Barthes in favour of Bataille.
North of Boston
Authors: Smith Virginia F.
Published: January 2020

North of Boston was published in 1914, just a year after A Boy's Will, while the Frost family was in England’s scenic West Country. The poems, many of which are long, dramatic narratives, are mostly inspired by the people, nature, and society of rural New England, but we do see some influence of his time in the United Kingdom, most notably in the poem “Mending Wall.” The poetic subjects and sources in North of Boston are similar to those in A Boy’s Will, but Frost introduces more precision into his poetry by using proper nouns and technical terms, especially those related to farming and botany. Poems such as “The Death of the Hired Man” and “After Apple-Picking” contain examples of specific agricultural and botanical language.
West-Running Brook
Authors: Smith Virginia F.
Published: January 2020

The years preceding the 1928 publication of West-Running Brook were a time of relative calm and prosperity for Frost and his family. Frost became a grandfather and received prestigious, and lucrative, college-level teaching appointments. The 1920s were a time of significant scientific discovery and technological innovation, especially in the areas of physics and astronomy. For example, the poems “A Passing Glimpse” and “A Never Naught Song” contain allusions to quantum mechanics and the Big Bang theory, respectively. The collection also has poems that address topics such as ecology (“A Winter Eden,” “The Bear”), observational astronomy (“Canis Major,” “Acquainted With the Night”), and natural transformations (“What Fifty Said,” “West-Running Brook,” “The Last Mowing.”) The lovely poem “Spring Pools” encapsulates the theme of natural change.
Phase-apodized-pupil Lyot Coronagraphs for Arbitrary Telescope Pupils
Authors: Por Emiel H.
Published: January 2020

The phase-apodized-pupil Lyot coronagraph (PAPLC) is a pairing of the apodized-pupil Lyot coronagraph and the apodizing phase plate (APP) coronagraph. We describe a numerical optimization method to obtain globally optimal solutions for the phase apodizers for arbitrary telescope pupils, based on the linear map between complex-amplitude transmission of the apodizer and the electric field in the post-coronagraphic focal plane. PAPLCs with annular focal-plane masks and point-symmetric dark zones perform analogous to their corresponding APLCs. However, with a knife-edge focal-plane mask and one-sided dark zones, the PAPLC yields inner working angles as close as 1.4λ/D at contrasts of 10−10 and a maximum post-coronagraphic throughput of >75% for telescope apertures with central obscurations of up to 30%. We present knife-edge PAPLC designs optimized for the VLT/SPHERE instrument and the LUVOIR-A aperture. These designs show that the knife-edge PAPLC retains its performance, even for realistic telescope pupils with struts, segments, and non-circular outer edges.
Line Lists for the
State of CS
Authors: Hou Shilin , Wei Zhengxing
Published: January 2020

Rotation-vibrational line lists for eight isotopologues of carbon monosulphide (CS; 12C32S, 12C33S, 12C34S, 12C36S,13C32S, 13C33S,13C34S, and 13C36S) in their ground electronic state (X1Σ+) are calculated. An empirical potential function with the corrections of Born–Oppenheimer breakdown effects, which are determined by a direct potential fitting approach using over 4300 observed transition frequencies of 12C32S, 12C33S, 12C34S, and 13C32S, is used in line list calculations. The reproduced transition frequencies are within the observation uncertainties for the isotopologues with experimental data. The dipole moment functions are calculated using an ab initio method at a multireference configuration interaction method/cc-pv5z level with a large active space of electronic configuration. The dipole moment at equilibrium nuclear separation is almost identical to the experimental result. The calculated intensities agree excellently with the laboratory observations at 2573 K. The corresponding Einstein A coefficients and oscillator strengths are predicted. Partition functions for temperatures up to 7500 K have been calculated. The line lists can be used for spectroscopic measurements of CS in astronomical environments of various temperatures.

Published: January 2020

We succeeded in observing two large spicules simultaneously with the Atacama Large Millimeter/submillimeter Array (ALMA), the Interface Region Imaging Spectrograph (IRIS), and the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory. One is a spicule seen in the IRIS Mg ii slit-jaw images and AIA 304 Å images (Mg ii/304 Å spicule). The other one is a spicule seen in the 100 GHz images obtained with ALMA (100 GHz spicule). Although the 100 GHz spicule overlapped with the Mg ii/304 Å spicule in the early phase, it did not show any corresponding structures in the IRIS Mg ii and AIA 304 Å images after the early phase. It suggests that the spicules are individual events and do not have a physical relationship. To obtain the physical parameters of the 100 GHz spicule, we estimate the optical depths as a function of temperature and density using two different methods. One is using the observed brightness temperature by assuming a filling factor, and the other is using an emission model for the optical depth. As a result of comparing them, the kinetic temperature of the plasma and the number density of ionized hydrogen in the 100 GHz spicule are ∼6800 K and 2.2 × 1010 cm−3. The estimated values can explain the absorbing structure in the 193 Å image, which appear as a counterpart of the 100 GHz spicule. These results suggest that the 100 GHz spicule presented in this Letter is classified to a macrospicule without a hot sheath in former terminology.

Published: January 2020

The relative average minimum projected separations of star clusters in the Legacy ExtraGalactic UV Survey (LEGUS) and in tidal dwarfs around the interacting galaxy NGC 5291 are determined as a function of cluster mass to look for cluster–cluster mass segregation. Class 2 and 3 LEGUS clusters, which have a more irregular internal structure than the compact and symmetric class 1 clusters, are found to be mass-segregated in low-mass galaxies, which means that the more massive clusters are systematically bunched together compared to the lower-mass clusters. This mass segregation is not present in high-mass galaxies or class 1 clusters. We consider possible causes for this segregation, including differences in cluster formation and scattering in the shallow gravitational potentials of low-mass galaxies.
Precise Measurements of the Speed of Light with High-redshift Quasars: Ultra-compact Radio Structure and Strong Gravitational Lensing
Authors: Cao Shuo , Qi Jingzhao , Biesiada Marek , Liu Tonghua , Zhu Zong-Hong
Published: January 2020

Although the speed of light has been measured with very high precision, most of these measurements were carried out on Earth or in our close cosmic surroundings. In this Letter, we propose an original idea to combine the observations of ultra-compact structure in radio quasars and strong gravitational lensing with quasars acting as background sources to estimate the speed of light. The method will provide precise measurements of the speed of light using extragalactic objects at different redshifts. We evaluate if current or future missions such as the Large Synoptic Survey Telescope (LSST) and Dark Energy Survey (DES) can be sensitive enough to detect any variation of c. Our results show that strongly lensed quasars observed by LSST would produce robust constraints on Δc/c at the level of 10−4, if the compact radio structure measurements are available.
A new species of Boholina (Crustacea, Copepoda, Calanoida) and a first record for stygobiotic calanoid fauna from a cave in Thailand
Authors: Boonyanusith Chaichat , Wongkamhaeng Koraon , Athibai Sujeephon
Published: January 2020

A new species of Calanoida belonging to the genus Boholina Fosshagen & Iliffe, 1989 was found in a freshwater pool within a cave of the Satun province, South Thailand. It is the first record of the genus and of a stygobiotic representative of calanoid fauna in this country. The new species is most similar to B. crassicephala Fosshagen & Iliffe, 1989, based on position of genital pores, structures of P4 and P5 in both sexes, relative length of subapical spine vestige on the male right P5, and shape of the male left P5 endopods. However, this new species is distinguished from its known congeners by: (1) relatively longer distal outer spines on the male right P5 exopods, (2) smaller endopods of the male left P5 and (3) elongated apical spines on the distal exopodal segment of the female P4 and P5. Furthermore, the distinctive characteristic of the Thai Boholina is the presence of inner minute seta on the distal segment of the male right P5 exopod. Detailed descriptions of the new species and a key to all six known species of the genus Boholina is provided.
Can We Differentiate Borderline Personality Disorder from Bipolar Disorder?
Authors: Li Benjamin , Valles Nizete-Ly , Saunders John , Vyas Amy , Naqvi Mohammad , Shah Asim A.
Published: January 2020

Distinguishing between borderline personality disorder and bipolar disorder is challenging due to symptom overlap. However, through careful screening and history-taking, collateral information from sources familiar with the patient, and the use of appropriate screening instruments, one may arrive at the correct diagnosis that will lead to optimal treatment planning. Clinicians must also recognize the possibility of the comorbidity of bipolar disorder and borderline personality disorder, and how such comorbidity may lead to poorer outcomes. This article reviews some of the key differences seen between borderline personality disorder and bipolar disorder in terms of neurobiology, heritability, longitudinal course, and subtle nuances in overlapping symptoms.

Is Borderline Personality Disorder a Serious Mental Illness?
Authors: Le Hai , Hashmi Ali , Czelusta Kim-Lan , Matin Asna , Moukaddam Nidal , Shah Asim A.
Published: January 2020

Historically, the term serious mental illness (SMI) has referred to bipolar, schizophrenia, and severe depression, which are conditions that are well studied and discussed. Although there have been inconsistent definitions of SMI in the United States, the one with the broadest consensus is that of the National Institutes of Mental Health (NIMH), which includes personality disorders. Borderline personality disorder (BPD), one of the most common problems encountered in psychiatry practice, has distinctive characteristics and associated severe functional impairment that fits the NIMH definition of SMI. BPD can also lead to poor general health and lower life expectancy from causes such as suicide, substance abuse, and poor physical health. In this article, we explore the background of various definitions of SMI and why BPD should be classified as an SMI based on the definition set out by the National Institute of Mental Health. We also explore how BPD can develop into an SMI that makes early diagnosis and treatment imperative. Furthermore, we identify the issues of stigma and counter-transference that are routinely encountered by mental health providers and that can be barriers to appropriate treatment and optimal outcome.

Observational Experiential Learning: Theoretical Support for Observer Roles in Health Care Simulation
Authors: Johnson Brandon Kyle
Published: January 2020

Background:

Confusion remains about the use of the observer role in simulation. Observational learning is an emerging form of brain-based learning that is applicable to experiential learning and simulation, warranting the further exploration of theoretical foundations. This article describes how observational experiential learning theoretically supports the use of observer roles in simulation.

Method:

Constructs and concepts from experiential learning and observational learning theories were explored in tandem with brain-based learning evidence from different disciplines.

Results:

Observational experiential learning was developed by merging these theories together in simulation and debriefing to support both observer and participant roles for learning outcomes.

Conclusion:

Observational experiential learning incorporates experiential learning, social learning, and social cognitive theories to support the use of the observer role. Educators should consider strategies to foster attention and motivation through prebriefing, debriefing, and observational brain-based learning protocols.[J Nurs Educ. 2020;59(1):7–14.]

Authors: Markaki Adelais , Wingo Nancy , Watts Penni , Steadman Laura , Coles Karen , Rae Tania , Theus Lisa , Ortega Johis
Published: January 2020

Background:

Global organizations urge toward transformative, lifelong learning for nurses and midwives. Throughout Latin America and the Caribbean, strengthening the quality of nursing and midwifery education is top priority. A regional partnership of World Health Organization Collaborating Centers aimed to develop a user-friendly, culturally relevant, and adaptable educational quality improvement intervention.

Method:

Following the five-step ADDIE process, experts analyzed objectives and needs, designed activities and assessments, and determined optimum delivery of course content. A self-directed, asynchronous online course was developed, in line with regional needs and mandates. Three sequential online educational modules for English-speaking and Spanish-speaking nurse and midwife educators focused on (a) principles of teaching and learning, (b) instructional strategies, and (c) methods to evaluate students and courses. Content and design were externally reviewed and culturally adapted.

Conclusion:

Upon completion of pilot testing and evaluation, final course versions in both languages are expected to become freely accessible.

Vienne et Berlin, deux imaginaires opposés ?
Authors: Werth Eva
Published: January 2020

La modernité ne peut apparaître que dans les grandes villes qui, autour de 1900, sont en passe de devenir de véritables métropoles. Avec le progrès technique et industriel de l’imprimerie et la mise en réseau des pays par l’aménagement de l’infrastructure et le désenclavement des métropoles, l’information circule facilement. De plus, les vecteurs d’information voient s’élargir leur palette médiale, avec l’écriture mêlée à l’image dans les journaux, et le son diffusé à la radio ou sur gramophone. L’écrivain autrichien Hermann Bahr (1863-1934), qui séjourna à Berlin et Paris avant de regagner Vienne en 1891, fut particulièrement sensible à cette évolution médiale et interculturelle. Les pages culturelles des journaux (Feuilleton) de ces années-là sont le berceau d’une perception radicalement différenciée et polarisée de ces deux centres de la modernité. Hermann Bahr, passeur de frontières, décrit la modernité viennoise ex negativo en définissant la modernité berlinoise. La présente étude exposera sa définition de la modernité viennoise et de la modernité berlinoise pour revenir ensuite vers quelques exemples des villes urbaines dans les tableaux et les textes viennois et berlinois.

Improving the Employability of Mature Workers
Authors: Niu Yuanlu
Published: January 2020

The purpose of this chapter is to explore how organizations and higher education institutions can help mature workers maintain and improve their employability in the dynamic labor market. This chapter addresses the issues regarding career learning for mature workers and provides a guide for policymakers and human resource development (HRD) professionals for handling these issues. Several recommendations were generated for policy makers and HRD professionals: 1) the new trends manifested in local, regional, national, and global labor markets should be understood; 2) a more strategic policy to grow the availability and quality of jobs in aging labor markets should be developed; 3) mature workers' specific needs and interests should be recognized; 4) an age diverse environment should be developed in the workplace; 5) training and development programs to enhance transformational leadership behaviors should be provided to managers; and 6) longer-term personal development plans for mature workers should be established.

Authors: Frady Kristin K.
Published: January 2020

In today's war for talent, as the demographic landscape has shifted, firms who are leveraging the advantages of a more mature workforce may have strategic advantages. Indeed, the aging workforce is being acknowledged as an organizational phenomenon yet present scholarship on key organizational domains is both narrow and inconclusive. Specific strategies and tactics that focus on developing and recruiting a mature workforce to provide new opportunities for employers need to be more fully explored. The field of workforce development provides an approach through which to explore the intersection of the domains of mature workers and the dynamic employment needs of organizations and industry. Key components of workforce development such as partnerships, innovative workforce planning and recruitment practices, education and training, and career pathways will be examined to propose a practical framework and to provide using strategies and initiatives to strengthen the mature workforce.
Anti-Buckling Design of Rectangular Thin Plate Based on Local Surface Nanocrystallization
Authors: Lian Zeng Bo , Zhao Zhen , Xu Wang , Lim Chee Wah , Xu Xin Sheng , Zhou Zhen Huan
Published: January 2020

In this paper, a novel local surface nanocrystallization treatment is introduced to design the anti-buckling rectangular plate. The mechanical properties and critical buckling loads of the plates are greatly improved by the surface nanocrystallization technology. Several local nanocrystallization layouts, including the horizonal stripes distribution, the vertical stripes distribution and the spaced latticed blocks distribution, are designed and numerical simulations are carried out to evaluate the stability of the plates. Results show that the critical buckling load was significantly improved by the local nanocrystallization treatment. Among all the designs, the critical buckling loads for the vertical nanocrystallization layouts is the optimal one. And the technology can also be extended to the anti-buckling design of other structures.
Energy Absorption Analysis and Optimization Design of Local Surface Nanocrystallization Rectangular Tubes
Authors: Zhao Zhen , Wang Wei , Chen Ying Li , Zhou Zhen Huan , Lim Chee Wah , Xu Xin Sheng
Published: January 2020

A novel rectangular tube with circumferential anti-symmetric local self-surface nanocrystallization (CALSSN) layouts is designed for energy absorption. The effects of stripe numbers on the energy absorption performance is investigated. Results reveal that the 8-stripe CALSSN model exhibits the best buckling modes, which is more regular and stable than the untreated ones. It is also found that the stripe numbers highly depend on the structural sizes, unsuitable stripes number may reduce the buckling stability and periodicity. Besides, five CALSSN models with stripe numbers from 6 to 10 are selected to find the optimized size which has the highest specific energy absorption (SEA). A new 7-stripe CALSSN model which has optimal buckling modes and energy absorption performance is achieved.
Removal of Methylene Blue Dye Using Metal-Free g-C3N4 Photocatalyst over Natural Sunlight Irradiation
Authors: Sriwong Chaval , Choojun Kittisak
Published: January 2020

This work presented the high activity of metal-free g-C3N4 photocatalyst for methylene blue (MB) removing over natural sunlight irradiation. These g-C3N4 photocatalysts materials were synthesized by a conventional thermal condensation method using melamine as a precursor under treated at the various annealing temperatures (450 °C, 500 °C, 550 °C, 600 °C and 650 °C). All as-synthesized samples were characterized and confirmed by a several techniques, such as, X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR), UV-vis diffuse reflectance spectrometer (DRS), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS), and Brunauer-Emmett-Teller (BET) specific surface area. XRD and FTIR results confirmed that the as-synthesized g-C3N4 samples were completely synthesized at annealing temperature of 500 °C. SEM images showed the morphologies of the g-C3N4 samples had more flake-like structures upon the increasing of annealing temperatures. While DRS results indicated that the absorption edges of as-synthesized g-C3N4 samples were shifted to visible-light region, except the sample as-synthesized at 650 °C (g-C3N4-650 °C). Moreover, the photocatalytic properties of metal-free g-C3N4 photocatalyst materials were evaluated by degrading of MB dye solution under natural sunlight irradiation for 100 min. The results revealed that the highest photocatalytic activity was exhibited by the sample synthesized at 600 °C, which the apparent rate constant (kapp.) was 0.0291 min-1. The orders of activities as: g-C3N4-600 °C > g-C3N4-650 °C > g-C3N4-550 °C > g-C3N4-500 °C > g-C3N4-450 °C. Hence, the metal-free g-C3N4 photocatalyst appears to be an attractive-material for water or wastewater purification applications over activated by sunlight irradiation.
Microwave Absorption Properties of Porous Co/C Nanofibers Synthesized by Electrospinning
Authors: Sun Hai Tao , Zhang Sa , Deng Hui Yong , Cui Kai Bo , Zhao Fang
Published: January 2020

Porous Co/C composite nanofibers were fabricated by combination of electrospinning method and polymer blend. The phase composition, microstructure and electromagnetic characteristics of them were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and vector network analyzer (VNA), and their microwave absorption performances were studied. The results indicate that nanofibers were composited by amorphous carbon and face-centered cubic structured Co nanoparticle after sintering. The addition of PMMA is a key factor of nanofibers morphology and the aperture was improved with the increase of PMMA. When the thickness is 2.0 mm, the samples exhibit the best microwave absorption performance. Their effective absorpt ion bandwidths (RL < 10 dB) are 6.3 GHz, 6.2 GHz and 6.1 GHz, and it’s obviously superior to ordinary morphology nanofibers.

To know the fatigue damage state of X80 pipeline steel which is used for the drilling riser and prevent the occurrence of fatigue fracture accidents. Pulsating-impact-fatigue tests were conducted in laboratory, magnetic memory signals were measured during the whole fatigue process. The distribution of stress and magnetic field vector with different crack depth was analyzed by using finite element (FE) method. During fatigue crack initiation stage, magnetic signals increased slowly with fatigue loading cycles because of the effect of stress-magnetization. When fatigue crack appeared, magnetic signals were mainly affected by magnetic flux leakage (MFL) which was induced by fatigue crack. Magnetic memory characteristic parameters had a good linear relationship with fatigue crack depth. Magnetic memory signals were able to reflect the change of fatigue damage status.

Micro-arc oxidation (MAO) is known as a novel technique to use for the modifying the surface of valve metal, which improve mechanical and corrosion resistance properties. In this study, MAO coatings are fabricated on ALZ magnesium lithium alloy to protect the substrate from corrosion using environmentally friendly electrolytes under a high voltage power supply. The Taguchi method is used to identify the effects of current density, coating time and electrical frequency on the thickest coating uniformity. The optimum coating properties are characterized by coating thickness measurement, Scanning electron microscopy (SEM), Potentiodynamic polarization analysis. It was found that the processing time is the main factor affecting the thickest coating uniformity (tu). Coatings fabricated under optimum conditions are in close agreement with the predicted values of Taguchi analysis. The corrosion resistance of MAO coated on ALZ magnesium lithium alloy are greatly improved compare to the bare alloy in corrosive environments.

Published: January 2020

The microstructure and hardening behavior of HSLA steels with different microalloying element/carbon (M/C) atomic ratios, namely high M/C steel (H-M/C) and low M/C steel (L-M/C), were investigated in the present study. A dual precipitation morphology of nanosized carbides, namely interphase precipitation carbides and random precipitation carbides, was found at the same ferrite grain of both kind of steels, and these precipitates are believed to provide the main strengthening ability within ferrite. Of the two steels with different M/C atomic ratios, the ferrite matrix of H-M/C steel showed a rising trend in micro-hardness with increasing isothermal holding times from 5 min to 60 min at 650°C to 700°C. This higher strengthening ability occurring within ferrite grains after holding at longer times can be ascribed to the higher austenite decomposition rate occurring in the H-M/C atomic ratio steel. Therefore, the hardening mechanisms in both kinds of steel are also discussed in the present study.

Carbonated Hydroxyapatite Derived from Snail Shells (Pilla ampulacea): The Influence of Sintering Temperature on Purity and Crystallography Properties
Authors: Januariyasa I Komang , Yusuf Yusril
Published: January 2020

The aim of this work is to investigate the influence of sintering temperature on purity and crystallography properties of carbonated hydroxyapatite (CHAp). The CHAp was synthesized using a coprecipitation method. The snail shells (Pillaampulacea) were processed to yield calcium oxide as the calcium source in synthesis. The CHAp powder then was sintered for 2 h in an air atmosphere at 400, 600, 800, and 1000°C. An X-Ray diffractometer (XRD), Fourier transform infrared (FTIR), scanning electron microscope (SEM), and energy dispersive x-ray (EDX) are used to investigate the physicochemical properties of CHAp. XRD, FTIR, and EDS results show primary phase is carbonated hydroxyapatite. Calcium oxide as a secondary phase is detected starting from 800°C. The crystallinity and crystallite size are increased along the increasing of sintering temperature. Drastic enhancement on these properties is shown at 600–800°C. However, there is no simple relation to the sintering temperature and lattice parameters. These results show that sintering temperature has an important role in the purity and crystallography properties of the CHAp.

Metalworking fluids (MWFs) are widely used in the metal forming industrials. It was used for reducing of the friction and cooling of the mechanical processes. In this research, the modified sugarcane bagasse (MSB) with aluminium sulphate (Al2(SO4)3) was used as an adsorbent for removal of the metalworking fluid in Continuous Stirred Tank Reactor (CSTR). The point of zero charge of sugarcane bagasse and modified sugarcane bagasse were pH 6.1 and 3.7, respectively. The effect of initial concentration of metalworking fluid was studied. When used the reactor 3 L and flow rate at 0.055 L/min, the % removals of MWF at initial concentration 6,480-41,513 g/m3 were 98.0-56.7%, respectively. The significant uptake of metalworking fluid was demonstrated by FT-IR spectroscopy.

Published: January 2020

Traditional uvulectomy is not an uncommon practice in Nigeria and most part of sub-Saharan Africa. Its practice is well documented in these countries. Traditional uvulectomy and otitis media are both prevalent in Nigeria. However, there is a dearth of studies on a causal relationship between the two in the Nigerian subpopulation. This study aims to assess the pattern of otitis media among young children and adolescents who had traditional uvulectomy. This study was a prospective, descriptive, cross-sectional study conducted on all consecutive eligible consenting patients aged 5- to 18-years seen in the ear, nose and throat clinic of Aminu Kano Teaching Hospital with amputated uvula detected during routine examination were recruited. A standard tool was developed to obtain data from the patients. Thereafter otoscopy was done for all the patients. A total of 400 patients were recruited into the study, 246 (61.5%) were male and 154 (38.5%) female. The mean (standard deviation) of age was 12.4 (3.8) years. The commonest indication for traditional uvulectomy among the patients was as ritual [356 (89%)] with the least been speech disorder and failure to thrive [3 (76%)] each. Most (60%) had no symptoms suggestive of otitis media over the years. However, most (263 and 259 in the right and left ear respectively) participants had dull tympanic membrane on otoscopy. Majority (280) had their uvulectomy in the neonatal period, and post uvulectomy complications were low (17%). Symptoms of otitis media are not a common finding in patients with traditionally amputated uvulae.

One of the unusual symptoms observed among pregnant women is the aversion for non-food substances like sand, clay and ice. Pica is a form of eating disorder characterised by these symptoms. It occurs commonly in children and among pregnant women. This study aims to determine the prevalence and associated factors for Pica among booked patients in our institution. A prospective study was conducted among pregnant women at booking aged 11-45 years at the ATB University teaching Hospital Bauchi between 1st February to 31st of July 2019. All pregnant women who gave their consent were interviewed using a pretested questionnaire. The biodata, risk factors for Pica, occurrence in childhood and other social habits were recorded. The result showed a prevalence rate of pica at 38.9% with a craving for ice (18.7%), sand (14.7%) and others (55.11%). Pica was observed more in the day time (afternoon and evening) and most women having pica had a low level of education. Even though the prevalence of Pica appeared low in our environment, adequate counselling and appropriate treatment of women with this condition should be given more priority.
