Abstract:

AbstractPartial but significant localization along the line of sight (l.o.s.) of the contributions to the integrated zodiacal brightness can be achieved, without recourse to rash physical assumptions, if we focus on the two intersections between the l.o.s. and the terrestrial orbit. Then, there exists on the l.o.s. two other points or “nodes”, the contributions of which can be retrieved with outstandingly low uncertainty. The photometric results at these nodes (heliocentric change of scattering efficiency, backscattering phase function etc.) are highly reminiscent of previously ascertained features, and they encourage extensions to the polarimetric, the spectrometric and the radiometric cases. The salient results are, respectively: a positive radial gradient of local polarization degree; orbital velocities in excess over the keplerian ones, at least outside the earth’s orbit; the derivation of local temperatures from IRAS data.

Abstract. The new mission concept of microwave and infrared-laser occultation between low-Earth-orbit satellites (LMIO) is designed to provide accurate and long-term stable profiles of atmospheric thermodynamic variables, greenhouse gases (GHGs), and line-of-sight (l.o.s.) wind speed with focus on the upper troposphere and lower stratosphere (UTLS). While the unique quality of GHG retrievals enabled by LMIO over the UTLS has been recently demonstrated based on end-to-end simulations, the promise of l.o.s. wind retrieval, and of joint GHG and wind retrieval, has not yet been analyzed in any realistic simulation setting. Here we use a newly developed l.o.s. wind retrieval algorithm, which we embedded in an end-to-end simulation framework that also includes the retrieval of thermodynamic variables and GHGs, and analyze the performance of both stand-alone wind retrieval and joint wind and GHG retrieval. The wind algorithm utilizes LMIO laser signals placed on the inflection points at the wings of the highly symmetric C18OO absorption line near 4767 cm−1 and exploits transmission differences from a wind-induced Doppler shift. Based on realistic example cases for a diversity of atmospheric conditions, ranging from tropical to high-latitude winter, we find that the retrieved l.o.s. wind profiles are of high quality over the lower stratosphere under all conditions, i.e., unbiased and accurate to within about 2 m s−1 over about 15 to 35 km. The wind accuracy degrades into the upper troposphere due to the decreasing signal-to-noise ratio of the wind-induced differential transmission signals. The GHG retrieval in windy air is not vulnerable to wind speed uncertainties up to about 10 m s−1 but is found to benefit in the case of higher speeds from the integrated wind retrieval that enables correction of wind-induced Doppler shift of GHG signals. Overall both the l.o.s. wind and GHG retrieval results are strongly encouraging towards further development and implementation of a LMIO mission.

Abstract:

We use data from 58 strong lensing events surveyed by the Sloan Lens ACS Survey to estimate the projected galaxy mass inside their Einstein radii by two independent methods: stellar dynamics and strong gravitational lensing. We perform a joint analysis of both estimates examining the galaxy-lens density profile (that we approximate by a power law), the anisotropy of the velocity distribution (represented by an effective constant parameter), and a possible line-of-sigh (l.o.s.) mass contamination (which is suggested by various independent works in the literature). For each model, a likelihood analysis is performed to find the parameters that produce the best agreement between the dynamical and lensing masses, and the parameter confidence levels. The Bayesian evidence is calculated to allow a comparison among the models. We find a degeneracy among the slope of the density profile, the anisotropy parameter and the l.o.s. mass contamination. For a density profile close to isothermal, a l.o.s. mass contamination of the order of a few percent is possible, being less probable with larger anisotropy.

Abstract:

Abstract We present the joint Chandra, XMM-Newton, and NuSTAR analysis of two nearby Seyfert galaxies, NGC 3081 and ESO 565-G019. These are the only two having Chandra data in a larger sample of 10 low-redshift (z ≤ 0.05), candidates Compton-thick (CT) Active Galactic Nuclei selected in the 15–150 keV band with Swift-BAT that were still lacking NuSTAR data. Our spectral analysis, performed using physically motivated models, provides an estimate of both the line-of-sight (l.o.s.) and average (N H,S ) column densities of the two torii. NGC 3081 has a Compton-thin l.o.s. column density N H,z = [0.58–0.62] × 1024 cm−2, but the N H,S , beyond the CT threshold (N H,S = [1.41–1.78] × 1024 cm−2), suggests a “patchy” scenario for the distribution of the circumnuclear matter. ESO 565-G019 has both CT l.o.s. and N H,S column densities (N H,z > 2.31 × 1024 cm−2 and N H,S > 2.57 × 1024 cm−2, respectively). The use of physically motivated models, coupled with the broad energy range covered by the data (0.6–70 keV and 0.6–40 keV, for NGC 3081 and ESO 565-G019, respectively) allows us to constrain the covering factor of the obscuring material, which is C TOR = [0.63–0.82] for NGC 3081, and C TOR = [0.39–0.65] for ESO 565-G019.

Abstract:

Context. Isolated local group (LG) dwarf galaxies have evolved most or all of their life unaffected by interactions with the large LG spirals and therefore offer the opportunity to learn about the intrinsic characteristics of this class of objects. Aims. Our aim is to explore the internal kinematic and metallicity properties of one of the three isolated LG early-type dwarf galaxies, the Tucana dwarf spheroidal. This is an intriguing system, as it has been found in the literature to have an internal rotation of up to 16 km s−1, a much higher velocity dispersion than dwarf spheroidals of similar luminosity, and a possible exception to the too-big-too-fail problem. Methods. We present the results of a new spectroscopic dataset that we procured from the Very Large Telescope (VLT) taken with the FORS2 instrument in the region of the Ca II triplet for 50 candidate red giant branch stars in the direction of the Tucana dwarf spheroidal. These yielded line-of-sight (l.o.s.) velocity and metallicity ([Fe/H]) measurements of 39 effective members that double the number of Tucana’s stars with such measurements. In addition, we re-reduce and include in our analysis the other two spectroscopic datasets presented in the literature, the VLT/FORS2 sample by Fraternali et al. (2009, A&A, 499, 121), and the VLT/FLAMES one from Gregory et al. (2019, MNRAS, 485, 2010). Results. Across the various datasets analyzed, we consistently measure a l.o.s. systemic velocity of 180 ± 1.3 km s−1 and find that a dispersion-only model is moderately favored over models that also account for internal rotation. Our best estimate of the internal l.o.s. velocity dispersion is 6.2−1.3+1.6 km s−1, much smaller than the values reported in the literature and in line with similarly luminous dwarf spheroidals; this is consistent with NFW halos of circular velocities < 30 km s−1. Therefore, Tucana does not appear to be an exception to the too-big-to-fail problem, nor does it appear to reside in a dark matter halo much more massive than those of its siblings. As for the metallicity properties, we do not find anything unusual; there are hints of the presence of a metallicity gradient, but more data are needed to pinpoint its presence.

Abstract:

Context. The gamma-ray bursts hosts (GRBHs) are excellent targets to study the extinction properties of dust and its effects on the global emission of distant galaxies. The dust extinction curve is measured along the GRB afterglow line of sight and the analysis of the spectral energy distribution (SED) of the host galaxy gives access to the global dust attenuation of the stellar light. Aims. In this pilot study we gather information on dust extinction in GRBHs to compare the properties of the extinction curve to those of the dust obscuration affecting the total stellar light of the host galaxy. Assuming the extinction curve to be representative of the dust properties, we aim to investigate which dust-stars geometries and local dust distribution in the inter stellar medium (ISM) can reproduce the observed attenuation curve. Methods. We selected a sample of 30 GRBs for which the extinction curve along the GRB afterglow line-of-sight (l.o.s.) is measured in the rest-frame ultraviolet (UV) up to optical and we analysed the properties of the extinction curve as a function of the host galaxy properties. From these 30 GRBs, we selected seven GRBHs with a good rest-frame UV to near-infrared (NIR) spectral coverage for the host. The attenuation curve was derived by fitting the SEDs of the GRBH sample with the CIGALE SED fitting code. Different star formation histories (SFH) were studied to recover the star formation rates (SFR) derived using Hα luminosities. Implications for the dust-stars geometries in the ISM are inferred by a comparison with radiative transfer simulations. Results. The most extinguished GRBs are preferentially found in the more massive hosts and the UV bump is preferentially found in the most extinguished GRB l.o.s. Five out of seven hosts are best fitted with a recent burst of star formation, leading to lower stellar mass estimates than previously found. The average attenuation in the host galaxies is about 70% of the amount of extinction along the GRB l.o.s. We find a great variety in the derived attenuation curves of GRBHs, the UV slope can be similar, flatter or even steeper than the extinction curve slope. Half of the attenuation curves are consistent with the Calzetti attenuation law and there is evidence of a UV bump in only one GRBH. We find that the flatter (steeper) attenuation curves are found in galaxies with the highest (lowest) SFR and stellar masses. The comparison of our results with radiative transfer simulations leads to a uniform distribution of dust and stars in a very clumpy ISM for half the GRBHs and various dust-stars geometries for the second half of the sample.

Abstract:

Context. Dwarf galaxies found in isolation in the Local Group (LG) are unlikely to have interacted with the large LG spirals, and therefore environmental effects such as tidal and ram-pressure stripping should not be the main drivers of their evolution. Aims. We provide insight into the internal mechanisms shaping LG dwarf galaxies by increasing our knowledge of the internal properties of isolated systems. Here we focus on the evolved stellar component of the Aquarius dwarf galaxy, whose kinematic and metallicity properties have only recently started to be explored. Methods. Spectroscopic data in the region of the near-infrared Ca II triplet lines has been obtained with FORS2 at the Very Large Telescope for 53 red giant branch (RGB) stars. These data are used to derive line-of-sight (l.o.s.) velocities and [Fe/H] of the individual RGB stars. Results. We derive a systemic velocity of −142.2+1.8−1.8 km s−1, in agreement with previous determinations from both the HI gas and stars. The internal kinematics of Aquarius appears to be best modelled by a combination of random motions (l.o.s. velocity dispersion of 10.3+1.6−1.3 km s−1) and linear rotation (with a gradient −5.0+1.6−1.9 km s−1 arcmin−1) along a PA = 139+17−27 deg, broadly consistent with the optical projected major axis. This rotation signal is significantly misaligned or even counter-rotating to that derived from the HI gas. We also find the tentative presence of a mild negative metallicity gradient and indications that the metal-rich stars have a colder velocity dispersion than the metal-poor ones. Conclusions. This work represents a significant improvement with respect to previous measurements of the RGB stars of Aquarius as it doubles the number of member stars already studied in the literature. We speculate that the misaligned rotation between the HI gas and evolved stellar component might have been the result of recent accretion of HI gas, or re-accretion after gas-loss due to internal stellar feedback.

Abstract:

MG2016+112, discovered by Lawrence et al. (1984) is one of the best–studied among multiply–imaged systems, but is still only partially understood. Ostensibly a three–image system consisting of images A, B and C of a quasar at z = 3.273, the observed lensing galaxy D (a giant elliptical at z = 1.01) at the centroid of the image system seems inadequate to provide the minimum mass of ∼ 2.5 × 1012 M⊙ within 10 kpc of its center (in projection along the l.o.s.) required to produce the observed 3.″9 image–splitting. C itself appears to consist of two components, radio emission that may be associated with the faint optical image counterpart of A and B (called C2, see Garrett et al. 1994) and flat-spectrum C1, which dominates radio observations of the system and apparently consists of at least three linearly stretched subcomponents, C11 to C13 (see Garrett et al. in these proceedings).

Abstract:

Jalan Drs. Esau Sesa is a non-shared two-way connecting road owned by the Manokwari Regency Government, Papua Barat Province. This road is the main road that connects between districts with a road width of + 6 meters. The rapid development of land use along with Drs. Esau Sesa has the potential to reduce road service levels. Field observations showed that commercial activities are high in this area. Thus the traffic activities, as well as parked vehicles are also high, exceeding the facilities capacities. This condition is one of the causes of traffic jams on the road. Based on the data analysis results, Jalan Drs. Esau Sesa has a Road Capacity (C) of 2,061 vehicles/hour with a Free Flow Velocity (FV) of 45,315 Km/hour and a Degree of Saturation (DS) of 0.808. These results are equivalent to the Level of Service (L.O.S) at level D which means traffic flow on Jalan Dr. Esau Sesa began to become unstable, with low traffic jams with creeping currents and vehicle volumes approaching maximum capacity.

Abstract:

AbstractWe have completed a spectroscopic study of the “12.4 hr clump”, the second largest substructure in the Quasar Equatorial Survey Team (QUEST) catalog. First discovered as an over-density of RR Lyrae stars (Vivas et al. 2001, ApJL 554 33), the region containing the “12.4 hr clump” has generated much interest (Newberg et al. (2002), Martinez-Delgado et al. (2007), Juric et al. (2008), amongst many others). Our first spectroscopic study of this clump revealed the presence of a sharp peak in the radial velocity histogram for the candidate stars (Duffau et al. 2006). The combination of this result and metal abundance estimates for the sample was then interpreted as a signature of the presence of a stellar stream within the clump. This sub-structure was named the “Virgo Stellar Stream” (VSS), given its location in the direction of the Virgo Constellation, at approximately 20 kpc from the Sun. Several other groups have studied this region and have suggested that the over-density containing the VSS could extend to larger areas of the sky (outside QUEST's observing range). We present the complete spectroscopic follow up of the clump candidates present in QUEST and the composite of the studies we performed along the same l.o.s., including data at brighter magnitudes (Vivas et al. 2008). Our study confirmed the nature of the VSS, revealed its likely extent within the QUEST survey and defined a number of its relevant properties.

Abstract:

The first flow injection spectrophotometric method is characterized by its speed and sensitivity which have been developed for the determination of promethazine-HCl in pure and pharmaceutical preparation. It is based on the in situ detection of colored cationic radicals formed via oxidation of the drug with sodium persulphate to pinkish-red species and the same species was determined by using homemade Ayah 3SX3-3D solar flow injection photometer. Optimum conditions were obtained by using the high intensive green light emitted diode as a source. Linear dynamic range for the absorbance versus promethazine-HCl concentration was 0-7 mmol.L-1, with the correlation coefficient (r) was 0.9904 while the percentage linearity (r2%) was 98.09%. the L.O.Q was 3.97 µg/sample, while L.O.D (S/N=3) = 0.2407µg/sample (5 µmol.L-1) from the stepwise dilution for the minimum concentration of lowest concentration in the linear dynamic range of the calibration graph. The R.S.D% at 2 mmol.L-1 promethazine-HCl is less than 1% (eight replicates) using 150 µL sample volume. Throughput 30 sample.hr-1. The method was applied successfully for the determination of promethazine-HCl in pharmaceutical preparation. By using paired t-test it was shown that there was no significant difference between the proposed method and official method and on that basis the new method can be accepted as an alternative analytical method.

Abstract:

The L.O.L. Surprise doll was created in 2016 by MGA Entertainment inspired by the YouTube trend of “unboxing” videos, in which children and adults open toys packages, or other objects, and show to the viewers how it works or what it does. Being a collectible toy with the possibility of more than a hundred surprise dolls, L.O.L. Surprise, which is a best seller, explores playing from the unwrapping of the several layers involved in the unboxing of the doll’s package. The marketing of L.O.L. Surprise does not involve TV advertisements and all its strategy is focused on YouTube videos showing kids unboxing the toy. It is possible to perceive that opening the package, and consequently finding the doll, is part of the experience/play of L.O.L. Surprise. Since the rise of the North American doll L.O.L. is a trend not only in Brazil but all around the world (FROMM, 2019), it is a rising successful trend in last years (GREEN, 2018), this study aims at describing and analyzing the multimodal features of the layers of the doll’s package, perceiving how the surprise element is constructed through it. Therefore, to analyze the layers of the package, we will draw on Kress & Van Leeuwen’s Grammar of Visual Design (2006 [1996]) and its visual metafunctions, which derive from Halliday’s Systemic Functional Linguistics (1978). The description and analysis reveal a stimulus to children’s curiosity, enhanced by the interactive aspect perceived through the verbal and visual language, as well as a tendency towards consumerism and social media engagement.

Abstract:

This piece of research work aims to study one of the most difficult reaction and determination due to continuous and rapid variation of reaction products and the reactants. As molybdenum (VI) aid in the decomposition of hydrogen peroxide in alkaline medium of ammomia, thus means a continuous liberation of oxygen which cuases and in a continuous manner a distraction in the measurement process. On this basis pyrogallol was used to absorbe all liberated oxygen and the result is an a clean undisturbed signals. Molybdenum (VI) was determined in the range of 4-100 ?g.ml-1 with percentage linearity of 99.8% or (4-300 ?g.ml-1 with 94.4%) while L.O.D. was 3.5 ?g.ml-1. Interferring ions (cations and anions) were studied and their main effect was reduced using mini column cataining resin, or the separation of molybdenum via its precipitation prior to injection. The reaction system and manifold were used to determine pyrogallol (4-40 ?g.ml-1, L.O.D. 80 ?M) and hydrogen peroxide (0.1-5M, L.O.D. 50 mM). Relative standard diviation was better the 1%.

Abstract:

Since the beginning of Anglican missionary activity in the southwest Pacific in the mid-nineteenth century, fifteen European missionaries and at least seven Pacific Islanders have died violently in the course of their work. In that same region, comprising island Melanesia and New Guinea, Roman Catholics, Presbyterians, Methodists, and the London Missionary Society [L.M.S.] have each had their honour roll of martyrs. Three of these have achieved a measure of fame outside the Pacific and their own denomination: John Williams of the L.M.S., killed at Erromanga in Vanuatu (formerly the New Hebrides) in 1839; James Chalmers, also of the L.M.S., killed in New Guinea in 1901; and John Coleridge Patteson, Missionary Bishop of Melanesia and head of the Melanesian Mission, killed in 1871. Patteson has been the subject of more than fifteen biographies (several of them in German and Dutch), in addition to essays in collections on English missionary heroes, scholarly articles, and pamphlets for popular consumption. In Anglican churches in England, Australia, New Zealand, the United States, and elsewhere he is commemorated as missionary hero in memorial tablets and stained-glass windows.

Abstract:

An understanding of how variation is shared within and among closely related species is important for understanding evolutionary processes and managing biological diversity. We studied genetic structure in the three species occurring in south-western Australia that form the small and distinct monophyletic section Calophyllae of the genus Corymbia. We compared diversity in nuclear microsatellites and chloroplast DNA sequences in two species with patchy distributions, namely, Corymbia haematoxylon (Maiden) K.D. Hill & L.A.S. Johnson and Corymbia ficifolia (F. Muell.) K.D. Hill & L.A.S. Johnson, with that in the widespread congener, C. calophylla (Lindl.) K.D. Hill & L.A.S. Johnson. Consistent with predictions for the influence of range and abundance on genetic structure in the Australian flora, population differentiation was higher in the two restricted patchy species than in the widespread, semicontinuous C. calophylla. Genetic diversity in C. haematoxylon was similar to that in C. calophylla, but diversity was lower in the highly localised C. ficifolia, likely owing to genetic bottlenecks. All three species were distinguished by nuclear SSR variation, but C. haematoxylon and C. ficifolia each shared chloroplast haplotypes with C. calophylla from incomplete lineage sorting of ancestral variation and introgression. Limited evidence of recent hybridisation in two populations of C. haematoxylon was also present.

Abstract:

The thin polymer composite bipolar plates (the thickness < 1.5 mm) for use in polymer electrolyte membrane fuel cells (PEMFCs) containing vinyl ester resin, graphite powder, organoclay have been fabricated by bulk molding compound (BMC) process. Organoclay prepared by ionic exchange of montmorillonite (MMT) with three different Mw of diamine intercalating agents was used to reinforce the mechanical properties of the composite bipolar plates. Results indicate that the basal spacing and content of MMT varied with Mw of POP-diamines are critical in determining the resultant mechanical properties for bipolar plates. The flexural strength and the unnotched impact strength of the plate were ca. 38 % (from 30.21 MPa to 45.66 MPa) and ca. 30 % (from 58.11 J/m to 80.21 J/m) higher than the pristine graphite plate, respectively, as the basal spacing of MMT (2 phr) was increased from 1.71 to 5.43 nm. The limiting oxygen index (L.O.I.) and the UL-94 test revealed that the bipolar plate possesses excellent flame retardant with L.O.I. higher than 50 and UL-94-V0. In addition, the electrical conductivity of the bipolar plates with different MMT contents and basal spacing of MMT is higher than 100 S/cm.

Abstract:

This study aims to characterize and investigate properties of EAF slag waste obtained from Southern Steel Berhad, Penang (one of Malaysia’s largest steel makers), prior to its recycling into valuable products. Before characterization, lump form of the EAF slag was crushed into micron size powder. The properties investigated were loss of ignition (L.O.I.), chemical composition, leaching behavior, thermal properties and mineral phases present. Through XRF characterization, the chemical composition of the EAF slag was obtained. The slag was found to have extremely low L.O.I. (0.01 wt.%). Leaching test proved the slag is non-hazardous and safe to be handled. Meanwhile, thermal analysis (TGA) revealed the EAF slag is thermally stable and unlikely to decompose upon heating. Phase identification and quantification were performed by applying Rietveld refinement method. The EAF slag consisted of gehlenite (Al2O3.2CaO.SiO2 – 45.3 wt.%), larnite (2CaO.SiO2 – 21.0 wt.%), hematite (Fe2O3 – 13.4 wt.%) and wustite (FeO – 20.3 wt.%) mineral phases. The XRD profile fitted well with agreement indices of the refinement (Rwp: 6.658 and GOF: 2.588). The properties investigated in this study are expected to shed lights in evaluating the potential recycling of the EAF slag into various valuable products such as aggregate, brick, ceramic tile and cementing material.

Abstract:

Mistletoe is a common sight in mature eucalypt trees in Australia, especially in remnant stands in agricultural and pastoral areas, where they have been associated with debility and death. We surveyed over 450 eucalypt plantations in New South Wales, Australia, for mistletoe, and report for the first time that mistletoe infestation is becoming a problem in young eucalypt plantations. Forty-three plantations were infected, but only 9 of these had levels of mistletoe of 20% or more trees infected; 4 had levels of 38%, 40%, 65%, and 68%. Mistletoe was observed in plantations ranging in age from 3–10 years old. Species of Corymbia ( Corymbia maculata (Hook.) K.D. Hill & L.A.S. Johnson and Corymbia citriodora subsp. variegata (F. Muell.) K.D. Hill & L.A.S. Johnson) were the most susceptible to mistletoe. The mistletoe species Dendrophthoe vitellina (F. Muell.) Tiegh. was commonly observed in plantations in both lower and upper northeast New South Wales, while Amyema bifurcata (Benth.) Tiegh. was only observed in the upper northeast. We observed a significant impact on growth of mistletoe, affecting tree growth as young as four years old. Simulated analysis indicated that mistletoe infection can reduce stand basal area by 10% and stand volume by 13%. However, the impact of mistletoe on tree growth was variable across space and time.

Abstract:

Coppice growth on cut stumps in thinned Eucalyptus plantations has the potential to compete with and reduce the growth of retained sawlog crop trees (SCTs). This study examined to what extent SCT growth was reduced by coppice in two stands in southeastern Australia: (i) a Eucalyptus globulus Labill. plantation thinned at age 10 years and (ii) a slower growing Eucalyptus tricarpa L.A.S. Johnson & K. Hill (syn. Eucalyptus sideroxylon subsp. tricarpa L.A.S. Johnson) plantation thinned at age 62 years. After 5 years, thinning E. globulus from 850 to 400 trees·ha–1 increased the basal area of the largest diameter 200 SCTs·ha–1 (SCT200) by 11% when coppice was removed. There was no significant thinning response by SCT200 when coppice was retained. After 10 years, thinning E. tricarpa from about 600 to 100 trees·ha–1 increased the basal area of the largest diameter 100 SCTs trees·ha–1 (SCT100) by about 10% whether coppice was removed or not. At the time of measurement, coppice contributed 17% and 36% of stand sapwood area in thinned E. globulus and E. tricarpa treatments, respectively, and possibly competed with SCTs for water. This study shows the significant competitive effect that coppice can have in thinned eucalypt plantations and the importance of coppice management to the growth of retained trees.

Abstract:

This study aims to investigate the binding properties of co-fired fly ash (CFFA) in paste and mortar specimens. Paste specimens containing various CFFA proportions (25%, 50%, 75%, 100% by weight of cement) were conducted and evaluated using setting time tests, water demand tests and compressive strength tests. Mortar specimens containing various CFFA and Pulverised coal fly ash (PCFA) proportions (10%, 20%, 30% by weight of cement) were also conducted and compared with regard to flowability and compressive strength. The test results indicated that the water demand increased as the amount of CFFA replacement increased on the flow level at 110±3%; this is due to the higher ignition loss (L.O.I.). Higher L.O.I. values mean that there are more unburned carbon particles in the CFFA and that most of these carbon particles are porous. The compressive strength of mortar specimens decreased as the amount of CFFA replacement increased. Compared to the chemical compositions of cement (C3S, C2S), the main components of CFFA (Ca(OH)2, CaCO3, CaO) have lower crystalline strength and compactness. Therefore, the higher amount of CFFA replacement would inevitably cause a reduction of the cement contents of specimens, thereby reducing the compressive strength of the mortar specimens. Thus, an appropriate amount of superplasticiser and CFFA replacement in the mixture is useful with regard to the binding properties of cementitious materials.

Full text

Abstract:

Genetic control of vegetative propagation traits was described for a second-generation, outbred, intersectional hybrid family (N = 208) derived from two species, Corymbia torelliana (F. Muell.) K.D. Hill & L.A.S. Johnson and Corymbia variegata (F. Muell.) K.D. Hill & L.A.S. Johnson, which contrast for propagation characteristics and in their capacity to develop lignotubers. Large phenotypic variances were evident for rooting and most other propagation traits, with significant proportions attributable to differences between clones (broad-sense heritabilities 0.2–0.5). Bare root assessment of rooting rate and root quality parameters tended to have the highest heritabilities, whereas rooting percentage based on root emergence from pots and shoot production were intermediate. Root biomass and root initiation had the lowest heritabilities. Strong favourable genetic correlations were found between rooting percentage and root quality traits such as root biomass, volume, and length. Lignotuber development on a seedling was associated with low rooting and a tendency to poor root quality in cuttings and was in accord with the persistence of species parent types due to gametic phase disequilibrium. On average, nodal cuttings rooted more frequently and with higher quality root systems, but significant cutting type × genotype interaction indicated that for some clones, higher rooting rates were obtained from tips. Low germination, survival of seedlings, and rooting rates suggested strong hybrid breakdown in this family.

Abstract:

National attention was focussed on Utah in the Spring of 1983 when an abnormally deep snowpack in the mountains combined with abrupt, very warm weather to cause sudden, severe flooding along the state's densely populated Wasatch Front. Public officials were not prepared for what happened and they could not control the crisis generated problems with their own resources. A large, efficient, volunteer labor force was needed immediately to prevent serious flooding from becoming a disaster. The extensive media attention given to Utah during this period looked mostly at the way public officials and the people responded to the crisis. This is a report of voluntary labor and the floods of 1983 in Utah, The only public, semipublic, or private organization that could provide the number of volunteer workers that were necessary during the crisis period and supervise the workers adequately was the Church of Jesus Christ of Latter-day Saints (L.D.S.). The traditions, attitudes, and organization of the L.D.S. Church as they are important to the immediate delivery of large numbers of volunteer workers, equipment, and supervisors in an emergency period are investigated in this paper. The relationships between government in Utah and the Church are also examined to explain why the Church is relied on to supply the voluntary labor force for any mass emergency in Utah and how this is accomplished. The question is also addressed of whether or not the Utah experience would be either appropriate or transferable to any other area. There might he something to be learned from Utah that could aid disaster work elsewhere.

Abstract:

If driving has today really become a Western “metaphor for being” (Hutchinson), then common roadside signs proclaiming “Right lane must exit” or “Through traffic merge left”, inventions such as the automatic transmission, and the agreeable straightness of freeways can all be understood as symptoms of an ongoing socio-political struggle between the driver as democratic agent, and the state as institu-tionalized regulatory force. Nowhere is this more obvious than in the context of urban traffic, where private motorized transportation represents both the supreme (if illusory) expression of personal freedom, and official efforts to channel individualism by obliterating its sense of direction and ideological divergence. On the concrete proving grounds of the clogged inner-city freeway, “nomad science” and “state science” (Deleuze & Guattari) thus oscillate between the pseudo-liberatory expressivity of mainstream car culture and the self-effacing dromoscopic “amnesia of driving” (Baudrillard). Are a city’s multitudes of cars resistant “projectiles” (Virilio) or, rather, hegemonic “sites of containment” (Jane Jacobs)? This essay approaches the complex tensions between “untamable” democratic mobility and state-regulated transit by way of two Hollywood-produced films that focus on traffic in Los Angeles: in Collateral (2004), a cab driver comes to recognize and transcend the hopelessly directionless circularity dictated by his job; in Falling Down (1993), a frustrated civil service employee abandons his car on a rush-hour freeway and decides to walk home, forced to traverse the supposedly unwalkable city without the “masking screen of the windshield” (Virilio). As they “quit stalling”, both protagonists become dangerous variants of the defiant nomad – one a driver who remains on the road but goes “under the radar”, the other a transient pedestrian whose movement becomes viral and unpredictable. My analysis of the films’ metropolitan setting and of the incessant movement that marks both narratives links political and philosophical economies of motion, speed, and transit to a discussion of the various bandes vagabondage (Deleuze & Guattari) that are formed between city and driver, driver and car, and car and pedestrian. In this discussion, the inner-city road emerges as a primary site of conflict between civic rule and individual subject, and the flow of urban traffic comes to represent the tensions generated in spaces where movement is understood as both liberating and as a form of control.
