Abstract:

Reflecting the strong heritage of crystallographic research in Australia, we wish to present two of the public outreach projects that are underway down-under to celebrate International year of crystallography 2014. A project that is already up and running is Crystallography365 - Blogging a crystal structure a day at http://crystallography365.wordpress.com/. Gathering a group of, principally students and early career researchers based in Australia, each day during 2014 a different crystal structure will be presented and described. The goals of the project is to present the wide range of uses crystal structures have to a broad spectrum of sciences, and to provide an outlet for this group of scientists to engage with International Year of Crystallography. The other (hopefully bigger) project is Crystals in the city will run 9th-30 August 2014 (coinciding with National Science Week in Australia). A partnership between ANSTO and University of New South Wales, it will bring a public display of 10-15 person-size crystal structure models exhibited in cities around Australia. The goal is that the crystal structures will `reflect' their surroundings and instil pride among the public in the crystallographic achievements of Australian science. Accompanying the exhibition will be website, where the public can find more about each of the structures and students can learn of studying opportunities. The project will also unite a host of supporters and sponsors; universities, museums and crystallographic groups.

Abstract:

The key reason behind the richness of different structures and patterns displayed in nature is the universal mechanism of symmetry breaking. It shapes configurations at all length scales encountered in universe. Structures reached via symmetry breaking transitions are commonly described in terms of order parameter fields. One of the simplest systems where symmetry breaking concepts have already been explored in detail, are various liquid crystal (LC) phases. The reason behind this is rich variety of structures exhibited by LCs and their convenient experimental accessibility. Consequently, a wide spectrum of different theoretical tools have been developed in LCs. In this contribution the orientational ordering of housing block in San Francisco, which we choose as a typical large-city representative, was studied. Following nematic LC analogy we determine the local degree of ordering. The structural pattern of the city displays a domain-type pattern. The average degree of ordering within a domain strongly correlates with crime rate within it. Therefore, the results confirm an intuitive expectation that structures define properties. This model can be used as a helpful tool in education as it provides a way of understanding complex topics with the help of well-known every day phenomena. Key words: education, liquid crystal analogy, order parameter, city structure, crime rate, soft mater education.

Abstract:

AbstractPhacolite from Mitaki, Sendai City, Japan, has a core of penetration-twinned chabazite. The crystal has a convex (0001) face on which many twin individuals are produced by a two-dimensional nucleation mechanism, resulting in complicated twinning during growth. Both the r and the faces repeat finely during growth because of twinning, resulting in {112̄3} sectors with polysynthetic twinning. Finally, single structures nucleate on the crystal edges [211̄] and develop along the (112̄3) face, penetrating each other near the centre of the face.

Abstract:

The development and advance of city is the sign of human civilization, and the crystal of the mutual development of economy, politics, culture, and ecological environment for one age. In the ecological protection, Shenyang city has not protected and destroyed original public services from the view of cultural ecology. The cause is that Shenyang city lacks in the consciousness to maintain the ecology, which seriously influences the development of Shenyang city and threatens human healthy, and has been an important factor to restrain the sustainable development of the city (Li, 2008). Aiming at this problem, many countermeasures such as establishing the volunteer organization of ecological preservation and keeping feasible density are proposed in this article. With the development of the human society, the environment protection and ecology have been widely applied in various domains of the city. The development of the ecological concept has made the ecological city be one of the hottest topics nowadays. To maintain the city ecological system and build the city ecological figure is not closely related with the adjustment of Shenyang industrial structure, but directly influence the improvement of about seven millions denizens’ habitation condition in Shenyang. Therefore, the research and thinking about the ecological construction and preservation should be widely concerned by the whole society (Li, 2001).

Abstract:

Nowadays, secondary education provides a broad variety of different compulsory courses giving a solid basis for further student's progress at the university. However, there is an opinion that in this system we are losing the sense of adventures, discoveries and research. Now the main question is if we can efficiently combine compulsory subjects and open classrooms in order to support students in their self-realization needs and provoke interest in mundane school subjects. The educational course for pupils «Crystal Growth – from School Desk to Leading Scientific Research» began several years ago with close cooperation between Novosibirsk State University, the Institute of Solid State Chemistry and Mechanochemistry SB RAS and School #162 of Novosibirsk. The aim of the course is to provide further education in Chemistry and Crystallography via laboratory work and lectures, complementing the standard school program. We provide a targeted syllabus for students from 7 to 17 years old, covering related scientific topics starting from crystal symmetry to the basics of physical chemistry. Through close communication and interaction, pupils develop skills in growing crystals, paying particular attention to obtaining large single crystals of different substances. During the course, pupils crystallize more than 15 different substances using at least 5 different methods and their modifications. At the end of every year, the students are given the opportunity to carry out a personal project, calling on the new knowledge they have obtained from the course. Thus we can assume that an efficient program was developed and realized to support personal ideas and research for school students, based on compulsory subjects and modern experimental techniques. The work was supported by the grant of Dmitry Zimin Fund "Dynasty" "Entertaining Science for pupils" No.DP-55/13, Development Program of University Student Association, NSU, App. No.2012-PSO-225, City Hall grant for young scientists.

Abstract:

Purpose – The purpose of this paper is to consider the issue of forecasting hotel room rate with data from 2004 onwards and the forecast horizons of 91 observations. Design/methodology/approach – This study employs a set of time series data (91 observations) on average monthly hotel room rates to generate an Autoregressive Integrated Moving Average Models (ARIMA) forecasting model. Findings – Through the employment of 74 percent observations, with 26 percent withhold for evaluation checking, six best models are identified from 50 models under study. The final model reports a high level of predictive accuracy and provides useful insights for hoteliers to form business strategies. Originality/value – This research provides a well-defined model to forecast the room rate of three-star hotels in the city. The research findings provide good ground for strategic management of the industry, in which there is an imbalance between demand and supply of hotel accommodations. In addition, being the first of its kind in one of the largest gaming revenue generation city in the world, this research provides valuable information for further research of its kind in the future.

Abstract:

AbstractXRD analysis and electron microscopy show that hexagonal platy halloysite is the main component of an altered tuff (Ueno tuff bed) in the Pliocene Seto group, Aichi Prefecture, Central Japan. In the natural state it shows a single basal peak at 10·1 Å, which collapses to 7·2 Å, by dehydration through a segregate-type interstratification. The (02,11) non-basal band consists of slightly separated peaks which indicates moderate ordering of the crystal structure. The b-dimension is 8·936–8·939 Å. The stability of the interlayer water is intermediate with respect to halloysites of different morphologies. Between 3·5 and 4% Fe2O3 is present in the deferrated sample and the calculated chemical formula can not explain the anomalously high CEC of 21·9 mEq/100 g. Because the curvature radius and b-dimension of halloysite increase with increase in Fe2O3 content, the platy morphology is ascribed to replacement of Al3+ by Fe3+ in the octahedral sheet. Based on the geological and chemical data, the hexagonal platy halloysite is considered to have been formed from volcanic glass after deposition in a freshwater lake, where conditions were oxidizing and weakly acidic.

Abstract:

In this essay I draw from memory studies and Latin American cultural studies to reflect on Notas y Letras (Notes and Letters), a collaboration by the Nicaraguan band Nemi Pipali and the poet Adolfo Beteta. I analyze these artistic expressions, music and poetry, at their place of convergence—the city of Managua—making audible some of the mechanisms that combine symbolic universes in Nicaraguan culture. This transdisciplinary reading allows me to propose that 1) music becomes a social marker of performative memory, transmitted by sounds present in hybrid Latin American cities, and 2) the migrant subject is displaced and divided between the center and the periphery.

Abstract:

Abstract This paper presents the observed microphysical evolution of two coastal extratropical cyclones (19–20 December 2009 and 12 January 2011) and the associated passage of heavy snowbands in the cyclone comma head. The observations were made approximately 93 km east of New York City at Stony Brook, New York. Surface microphysical measurements of snow habit and degree of riming were taken every 15–30 min using a stereo microscope and camera, and snow depth and snow density were also recorded. A vertically pointing Ku-band radar observed the vertical evolution of reflectivity and Doppler vertical velocities. There were rapid variations in the snow habits and densities related to the changes in vertical motion and depth of saturation. At any one time, a mixture of different ice habits was observed. Certain ice habits were dominant at the surface when the maximum vertical motion aloft occurred at their favored temperature for depositional growth. Convective seeder cells above 4 km MSL resulted in relatively cold (less than −15°C) ice crystal habits (side planes, bullets, and dendrites). Needlelike crystals were prevalent during the preband period when the maximum vertical motion was in the layer from −5° to −10°C. Moderately rimed dendritic crystals were observed at snowband maturity associated with the strongest frontogenetical ascent on the warm (east) side of the bands. Riming rapidly decreased and more platelike crystals became more numerous as the strongest ascent moved east of Stony Brook. Snow-to-liquid density ratios ranged from 8:1 to 13:1 in both events, except during the period of graupel, when the ratio was as low as 4:1.

Abstract:

The work is devoted to the study of pollution by technogenic magnetic particles and heavy metals of soils in the city of Gubakha, Middle Ural (Russia). The aim of the work is the ecological and geochemical assessment of the elemental chemical composition of the soils of the city of Gubakha, and the establishment of the geochemical role of technogenic magnetic particles (TMPs). For the first time, the regularities of the spatial distribution of magnetic susceptibility in the soils of the city of Gubakha were revealed, and the morphology, elemental and mineralogical compositions of magnetic particles in the soils of an industrial city in the Middle Urals were characterized using the methods of the chemical extraction of iron compounds, magnetic separation, ESEM/EDS, and Mössbauer spectroscopy. The magnetic phase of soils contains magnetite/maghemite, hematite, pyrrhotite, intermetallic alloys and chromite. Spherical magnetic particles are hollow, and have a magnetite shell and a varied surface texture. The crystal lattice of magnetite is characterized by low stoichiometry. The heavy metals Zn, Cu, Ni and Cr are concentrated in magnetic particles and have a high correlation coefficient with magnetic susceptibility. The level of contamination of Cu, Ni, Zn, Cr and Mn in the soils of a residential zone of Gubakha, estimated by the value of the pollution load index (PLI), was high. The Igeo index for Fe ranges from 6.2 to 12.2, for Cu–1.1 and Ni–1.1. The combination of methods for measuring magnetic susceptibility, determining the mineralogical composition of iron compounds, and determining the elemental chemical composition by X-ray fluorescence, has shown the effectiveness of an integrated approach for carrying out an ecological–geochemical assessment of the soil cover of Gubakha.

Abstract:

Objectives: The aim of this study is to understand better the service implications of patients presenting to an inner city Australian Emergency Department (ED) and Acute Psychiatric Inpatient Service (AIS) with a history of recent crystal methamphetamine use. Methods: An audit was taken of all patients with recent crystal methamphetamine use presenting to St Vincent’s Hospital Melbourne ED and AIS over the month of September 2017. Recorded information included patient demographics, diagnosis, aggressive episodes, restrictive interventions and other risk incidents. Results: Methamphetamine was related to 21.7% of AIS admissions. Of these individuals, half were involved in aggression towards staff. In the ED, 65.7% of patients with amphetamine use were aggressive to staff and 50% were aggressive towards other patients. There were high rates of physical (69.2%) and mechanical restraint (61.5%) in the ED setting. Methamphetamine use in the AIS was commonly associated with enduring psychotic disorders, whilst those managed exclusively in the ED were most commonly in an acute intoxicated state. Conclusions: Methamphetamine use presents a significant challenge to EDs and acute mental health services. Additional resources are required to manage these patients and their impact on the health system needs to be factored into future service planning.

Abstract:

The crystal structure of dmisteinbergite has been determined using crystals from the type locality in Kopeisk city, Chelyabinsk area, Southern Urals, Russia. The mineral is trigonal, with the following structure: P312, a = 5.1123(2), c = 14.7420(7) Å, V = 333.67(3) Å3, R1 = 0.045, for 762 unique observed reflections. The most intense bands of the Raman spectra at 327s, 439s, 892s, and 912s cm −1 correspond to different types of tetrahedral stretching vibrations: Si–O, Al–O, O–Si–O, and O–Al–O. The weak bands at 487w, 503w, and 801w cm−1 can be attributed to the valence and deformation modes of Si–O and Al–O bond vibrations in tetrahedra. The weak bands in the range of 70–200 cm−1 can be attributed to Ca–O bond vibrations or lattice modes. The crystal structure of dmisteinbergite is based upon double layers of six-membered rings of corner-sharing AlO4 and SiO4 tetrahedra. The obtained model shows an ordering of Al and Si over four distinct crystallographic sites with tetrahedral coordination, which is evident from the average <T–O> bond lengths (T = Al, Si), equal to 1.666, 1.713, 1.611, and 1.748 Å for T1, T2, T3, and T4, respectively. One of the oxygen sites (O4) is split, suggesting the existence of two possible conformations of the [Al2Si2O8]2− layers, with different systems of ditrigonal distortions in the adjacent single layers. The observed disorder has a direct influence upon the geometry of the interlayer space and the coordination of the Ca2 site. Whereas the coordination of the Ca1 site is not influenced by the disorder and is trigonal antiprismatic (distorted octahedral), the coordination environment of the Ca2 site includes disordered O atoms and is either trigonal prismatic or trigonal antiprismatic. The observed structural features suggest the possible existence of different varieties of dmisteinbergite that may differ in: (i) degree of disorder of the Al/Si tetrahedral sites, with completely disordered structure having the P63/mcm symmetry; (ii) degree of disorder of the O sites, which may have a direct influence on the coordination features of the Ca2+ cations; (iii) polytypic variations (different stacking sequences and layer shifts). The formation of dmisteinbergite is usually associated with metastable crystallization in both natural and synthetic systems, indicating the kinetic nature of this phase. Information-based complexity calculations indicate that the crystal structures of metastable CaAl2Si2O8 polymorphs dmisteinbergite and svyatoslavite are structurally and topologically simpler than that of their stable counterpart, anorthite, which is in good agreement with Goldsmith’s simplexity principle and similar previous observations.

Abstract:

Background Bacterial vaginosis (BV) is one of the most common vaginal infections worldwide. It is associated with the presence of a dense polymicrobial biofilm on the vaginal epithelium, formed mainly by Gardnerella species. The biofilm also contains other anaerobic species, but little is known about their role in BV development. Aim To evaluate the influence of different culture media on the planktonic and biofilm growth of six cultivable anaerobes frequently associated with BV, namely Gardnerella sp., Atopobium vaginae, Lactobacillus iners, Mobiluncus curtisii, Peptostreptococcus anaerobius and Prevotella bivia. Methods A total of nine different culture media compositions, including commercially available and chemically defined media simulating genital tract secretions, were tested in this study. Planktonic cultures and biofilms were grown under anaerobic conditions (10% carbon dioxide, 10% helium and 80% nitrogen). Planktonic growth was assessed by optical density measurements, and biofilm formation was quantified by crystal violet staining. Results Significant planktonic growth was observed for Gardnerella sp., A. vaginae and L. iners in New York City III broth, with or without ascorbic acid supplementation. Biofilm quantification showed high in vitro biofilm growth for Gardnerella sp., P. anaerobius and P. bivia in almost all culture media excluding Brucella broth. Contrary, only New York City III broth was able to promote biofilm formation for A. vaginae, L. iners and M. curtisii. Conclusions Our data demonstrate that New York City III broth relative to the other tested media is the most conducive for future studies addressing polymicrobial biofilms development as this culture medium allowed the formation of significant levels of single-species biofilms.

Abstract:

CRYSTAL ball-gazing has become a favourite occupation in Hong Kong as the territory moves closer to the changeover of sovereignty on July 1, 1997. In a city where speculation fuels the money markets, second guessing about corporate futures is commonplace throughout the business community. The “what will happen in 1997?” question inevitably focuses on the post-colonial future of English in Hong Kong. English, the official language of government and commerce, is set to be replaced by Chinese as the primary language of administration according to the Basic Law, the territory's future constitution. This move has particular relevance for the territory's promotional industries, currently employing one per cent of the population in advertising and public relations (Vocational Training Council, 1996).

Abstract:

The specific activity of natural radionuclides in 24 soil samples collected from antiquities area of Ur city in Dhi-Qar province (31.0459863N, 46.2534257E) in southern Iraq have been studied and evaluated. Experimental results were obtained by using a Gamma ray spectrometer analysis system consists of a scintillation detector Sodium Iodide activated by Thallium NaI(Tl) of (3"×3") crystal dimension at the laboratory of radiation detection and measurement in Science Collage, University of Kufa. The spectrometer has been calibrated for energy by acquiring a spectrum from four standard sources of gamma radiations supplied by spectrum techniques (LLC). The measuring time of all soil samples is 18000 seconds; it was found that, the soil specific activity ranges from 29.93±2.97 to 9.99±2.56Bq/kg for 238U, from 25.66±2.55 to 7.77±2.24Bq/kg for 232Th and from 397.38±12.06 to 215.75±8.91Bq/kg for 40K, with mean values of 17.9±3.02Bq/kg, 13.66±2.41Bq/kg and 314.62±11.3Bq/kg, respectively. The results have been compared with the acceptable data of the worldwide literatures. In order to evaluate the radiological hazard of the natural radioactivity, the radium equivalent activity (Raeq), the gamma absorbed dose rate (AD), the annual effective dose rate and the both (external and internal) hazard index have been calculated and compared with the acceptable values of the worldwide average (UNSCEAR 2000).

Abstract:

The data on the Silurian Sm–Nd age (426 ± 34 Ma) behind the arc-spreading dolerites of the sheeted dikes of Mount Azov in the Middle Urals was obtained. This age coincides with the age of zircons (428,5 ± 3,7 Ma) from the dolerites of the East-Ural megazone, which indicates the regional nature of the back-arc spreading processes. A study of the crystal ontogeny and composition of inclusions of metamorphogenic minerals in Mid-Upper Devonian zircons from the dikes of the city of Azov showed that the formation of zircons took place in the course of regional metamorphism of dolerites and enclosing basalts. This metamorphism coincides with the time of the onset of the collision in the late Devonian, and conflict processes manifested themselves over practically the entire width of the region.

Abstract:

The polite world took little interest in the Alps before the 18th century. The local inhabitants had ventured far enough to shoot chamois and to search for crystal (i.e. quartz), but few of the educated took any notice. The earliest natural philosophers to study the botany and mineralogy of these regions were from the German–speaking towns of Switzerland. Their first conclusions have not always stood the test of time; one of them, J.J. Scheuchzer (F.R.S., 1703) even reported the presence of dragons. Such frivolities did not appeal to the Calvinists of the city republic of Geneva. They could see the ‘montagnes maudites’ of Savoy to the south–east, but they never went to them. The first serious attempts to describe this world of snow and ice were made in 1741 and 1742.

Abstract:

The city of Ferrol was designed ‘ex-novo’ by military engineers to serve the Spanish monarchy and to house its naval base and dockyards. The principles of stratification on which society was based, and the need to defend the city from enemy attacks and to discipline workers led to a spatial plan that segregated the Navy officers and the working classes. In the nineteenth century, the naval base and the enclave economy of Ferrol became obsolete. Furthermore, the new political culture of the nation state and liberal democracy complicated further the task of controlling the working class. The Spanish Civil War allowed for the updating of Ferrol's spatial plan thanks to the identification of a single enemy both inside and outside: the political repression of the working-class became a major issue in the victory against the II República. The Franco regime meant the return of a segregated and militarized Ferrol, whereas in the 1980s, European integration and the transition to democracy made this model obsolete.It was clearer than crystal to the lords of the State preserves of loaves and fishes, that things in general were settled for ever.
