'Dripping sweat: sub-tropical spaces in recent Brisbane fiction'

This paper considers the literary landscape of contemporary Brisbane and pays particular attention to the relationship between sub-tropical spaces (homes, streets, and clubs) and local writing. ‘Dripping Sweat’ proposes that within the new urban cool of Brisbane’s cultural life there is nostalgia for the sub-tropical environment that continues to intrude on contemporary fiction. The paper considers the architecture of both public and private spaces and discusses how the literary imagination re-designs contemporary Brisbane with a selective appropriation of environmental settings.

Was By The Northern Coast

‘Was by the Northern Coast’ was an installation at MetroArts in Brisbane. A pile of warped timber, evocative of a dismantled boat, sits in the middle of the gallery space on a bed of carefully-laid bands of polyester insulation and pine battening. From within the wood stack, the sound of dripping water indicates the flow of water created by a silent internal pump. The sound of water intermingles with a soft soundtrack of Kulning, an archaic form of Scandinavian song. In ‘Was by the Northern Coast’, the detritus of timber mimics the Romantic sublime of the mountain peak and nautical wreckage while the snowy drifts of the Northern European landscape become mistranslated as a field of artificial ceiling insulation. In employing such slippages, the work attempted to create the imaginative landscape of an aesthetic displaced by distance and time.

Laboratory Test Methods For The Evaluation Of Flammability Of Polymers

Combustion is a complex phenomena involving a multiplicity of variables. Some important variables measured in flame tests follow [1]. In order to characterize ignition, such related parameters as ignition time, ease of ignition, flash ignition temperature, and self-ignition temperature are measured. For studying the propagation of the flame, parameters such as distance burned or charred, area of flame spread, time of flame spread, burning rate, charred or melted area, and fire endurance are measured. Smoke characteristics are studied by determining such parameters as specific optical density, maximum specific optical density, time of occurrence of the densities, maximum rate of density increase, visual obscuration time, and smoke obscuration index. In addition to the above variables, there are a number of specific properties of the combustible system which could be measured. These are soot formation, toxicity of combustion gases, heat of combustion, dripping phenomena during the burning of thermoplastics, afterglow, flame intensity, fuel contribution, visual characteristics, limiting oxygen concentration (OI), products of pyrolysis and combustion, and so forth. A multitude of flammability tests measuring one or more of these properties have been developed [2]. Admittedly, no one small scale test is adequate to mimic or assess the performance of a plastic in a real fire situation. The conditions are much too complicated [3, 4]. Some conceptual problems associated with flammability testing of polymers have been reviewed [5, 6].

Self-similar breakup of near-inviscid liquids

The final stages of pinchoff and breakup of dripping droplets of near-inviscid Newtonian fluids are studied experimentally for pure water and ethanol. High-speed imaging and image analysis are used to determine the angle and the minimum neck size of the cone-shaped extrema of the ligaments attached to dripping droplets in the final microseconds before pinchoff. The angle is shown to steadily approach the value of 18.0 ±0.4, independently of the initial flow conditions or the type of breakup. The filament thins and necks following a τ2 /3 law in terms of the time remaining until pinchoff, regardless of the initial conditions. The observed behavior confirms theoretical predictions. © 2012 American Physical Society.

Preparation and properties of a novel nonionic surfactant grafted linear low density polyethylene

A novel nonionic surfactant, glycerol monostearic acid monomaleic acid diester (GMMD) was synthesized in our laboratory. Grafting-copolymerization of linear low density polyethylene (LLDPE) with GMMD was carried out by using P-ray irradiation in a twin-screw extruder. Evidence of the grafting of GMMD, as well as its extent, was determined by FT-IR. The effects of monomer concentration, reaction temperature and screw run speed on degree of grafting were studied systematically. The thermal behavior of LLDPE-g-GMMD was investigated by using differential scanning calorimety (DSC). Compared with neat LLDPE, the crystallization temperature (T,) of LLDPE-g-GMMD increased about 3 degrees C, and the melting enthalpy (Delta H-m) decreased with increase of GMMD content. It showed that the arafted GMMD monomer onto LLDPE acted as a nucleating agent. The tensile properties and light transmission of blown films were determined. Comparing with neat LLDPE film, no obvious changes could be found for the tensile strength, elongation at break and right angle tearing strength of LLDPE-g-GMMD film. Accelerated dripping property of film samples was investigated. The dripping duration of LLDPE-g-GMMD film and commercial anti-fog dripping film at 60 degrees C were 52 days and 17 days, respectively.

石笋微层序列的断代和信号研究

Based on chronological and climatologic analysis of many young stalagmites in Shihua Cave at Beijing and Water Cave in Benxi, Liaoning Province, this dissertation aims to discuss some key points on quantitative reconstruction of high resolution climate change from micro bands time series in young stalagmites. On chronological aspect of micro bands time series in young stalagmite, the uppermost micro bands were testified formed in the sampling year or the year before sampling from long term and in situ experiment in Shihua Cave at Beijing. Have been observed detailed under microscope, the micro bands were counted and compared with high resolution TIMS-230Th or ICP-MS U series dating, the results show that the micro bands are annual bands. The microscopic characteristics of annual bands in North China is as follows after studying lots of young stalagmites: the interface appears to be carved, and there is a light line adjacent to it, which moves back and forth slightly when adjusting the microscope slide. The cross dating of annual bands from different stalagmites is experimented in this thesis. On climatologically aspect of micro bands times series in young stalagmites, one significant problem is that the deposition trend resulting from the variation of the stalagmite shape. Various deposition trends have been discussed and corrected before climatologically analysis of micro bands series. And the whole year in situ observation and analysis of dripping water in Shihua Cave provide us new evidence for climate information reserved in stalagmites micro bands. The stalagmites in the same cave may contain different climate information due to the micro hydrological condition. The annual bands of young stalagmites collected from North China can be used to reconstruct past climate changes quantitatively. The warm season temperature (May, June, July, August) is reconstructed using two annual bands time series from Shihua Cave, Beijing, which corresponds to the warm/cool periods very well in Chinese history documents. The precipitation record of past 500 years is reconstructed using two stalagmite annual bands series from Shihua Cave, which is consistent to the dryness/wetness records derived from historical documents too.

Complex dynamics in simple systems with periodic parameter oscillations

We study systems with periodically oscillating parameters that can give way to complex periodic or nonperiodic orbits. Performing the long time limit, we can define ergodic averages such as Lyapunov exponents, where a negative maximal Lyapunov exponent corresponds to a stable periodic orbit. By this, extremely complicated periodic orbits composed of contracting and expanding phases appear in a natural way. Employing the technique of ϵ-uncertain points, we find that values of the control parameters supporting such periodic motion are densely embedded in a set of values for which the motion is chaotic. When a tiny amount of noise is coupled to the system, dynamics with positive and with negative nontrivial Lyapunov exponents are indistinguishable. We discuss two physical systems, an oscillatory flow inside a duct and a dripping faucet with variable water supply, where such a mechanism seems to be responsible for a complicated alternation of laminar and turbulent phases.

Padrão de distribuição de K+, Ca++, Mg++ e P no solo de um pomar de citros em função da fertirrigação

Em solos tropicais, a distribuição dos nutrientes no solo em função da fertirrigação realizada por meio de irrigação localizada (gotejamento e/ou microaspersão), na cultura de citros, é pouco conhecida. Este trabalho teve por objetivo avaliar os padrões de distribuição de potássio, cálcio, magnésio e fósforo em solo tropical, em função da fertirrigação, aplicada por dois sistemas de irrigação localizada (microaspersão e gotejamento), sendo que o sistema por gotejamento era composto por uma e duas linhas laterais por linha de plantas, e o de microaspersão por apenas uma linha, e com três dotações hídricas (100%, 75% e 50%) da evapotranspiração da cultura (ETc), em um pomar de laranjeira. As fontes de fertilizantes utilizadas na fertirrigação foram o nitrato de amônio (fonte de N), o cloreto de potássio (fonte de K+) e o ácido fosfórico (fonte de P). Observouse que, sob o emissor, nos tratamentos com gotejamento, houve depleção nos teores de Ca++ e Mg++ desde a superfície do solo até 60 cm de profundidade em relação aos teores anteriores às fertirrigações, enquanto os teores de P aumentaram, principalmente na camada de 0 cm a 20 cm. Na microaspersão, esses efeitos não foram observados, ocorrendo distribuição mais homogênea desses nutrientes tanto na direção transversal à linha de plantas quanto em profundidade. As lâminas de irrigação aplicadas por irrigação localizada não interferem na distribuição de K+ aplicado por fertirrigação e do Ca++ e Mg++ no solo em profundidade, porém menores lâminas de irrigação promovem maior concentração de P na camada mais superficial do solo, e lâminas maiores carregam o P para camadas mais profundas.

Produção e qualidade de melão rendilhado sob diferentes substratos em cultivo protegido

This paper aimed to evaluate the performance of hybrids of muskmelon on different substrates. Five substrates were evaluated: S(1) = coconut husk fiber, S(2) = sand; S(3) = 1/2 sand and 1/2 crushed of sugarcane, S(4) = 1/2 sand and 1/2 of peanut shell, and S(5) = 1/3 sand, 1/3 of crushed sugarcane and I of peanut shell and four hybrids of muskmelon (Bonus N(o). 2, Louis, Fantasy Jab and 2007 # 16). The plants were cultivated in plastic pots of 13 dm(3), which were filled with these substrates; they were arranged in plants spacing of 1,0 x 0,5 m between plants. The Fertirrigation was done by dripping, using a nutrient solution for the culture. The experimental design was a randomized blocks, in a 5 X 4 factorial design with four replications. The characteristics evaluated were: total production, average transverse and longitudinal diameter of fruit, fruit shape index; mesocarp thickness; average transverse and longitudinal diameter of the locule; index format locule; mass of fresh fruit; soluble solids, pH; titratable acidity; C vitamin; firmness of flesh; tracery of shell; and maturation index. The optimal substrate for muskmelon cultivation is a combination of 50% sand + 50% peanut shell. The hybrid Fantasy performed better compared to other hybrids.
