description: This paper presents the observations and findings from an experimental study for dispersion of multiwalled carbon nanotubes (MWCNTs) by bath ultra-sonication in the presence of polycarboxylate ether (PCE) based superplasticizer. Commercial brand of superplasticizer (SP) compatible with cement was adopted for exploring its usage as surfactant during aqueous dispersion of MWCNTs. Cement composite pastes were evaluated for variation in compressive strength and fresh property for a fixed addition percentage of MWCNT. Aqueous dispersion of MWCNTs for incorporation to cement pastes was prepared considering three different sonication process variables; time period of sonication, SP to MWCNT dosage during sonication and temperature of sonication medium. A total of 168 experimental variations were evaluated for compressive strength of resulting cement–carbon nanotubes composite pastes at 7 days age to arrive at an optimal process of bath ultra-sonication with governing variables. Results showed that a sonication time period in the range of 4–5 hours with an SP to MWCNT ratio of 2.5–3 was necessary for satisfactory dispersion of MWCNTs over different temperature ranges of sonication bath medium. Further, the temperature of sonication medium in the range of 35–40°C during aqueous dispersion of MWCNTs was observed to induce noticeable enhancement in strength of composite system indicating improvement in dispersion within an optimal range of sonication medium temperature. Microscopic observations for optimal process variables of dispersion during bath ultra sonication showed evidence of physical changes in MWCNTs from an agglomerated state of particles to separated state. Bath ultra-sonication is explored for dispersion of Multi-walled carbon nanotubes (MWCNTs) with cement compatible Poly carboxylic Ether based Superplasticizer (SP) as a surfactant for benefit of large-scale application in the construction sector. Total of 168 experimental variations studied considering three process variables: Time of sonication; dosage of superplasticizer during sonication with respect to MWCNT weight and temperature of sonication bath. Compressive strength variation for the composite system used for arriving at optimal sonication process variables. Noticeable effects in the composite system were observed for minimum 4 hours of bath ultra-sonication with SP to MWCNT ratio of 2.5 and for a sonication temperature of 35 °C.

description: We present a calculation of the full set of next-to-next-to-leading-order QED corrections to unpolarised Møller scattering. This encompasses photonic, leptonic, and non-perturbative hadronic corrections and includes electron mass effects as well as hard photon radiation. The corresponding matrix elements are implemented in the Monte Carlo framework McMule allowing for the computation of fully-differential observables. As a first application we show results tailored to the kinematics and detector design of the PRad II experiment where a high-precision theory prediction for Møller scattering is required to achieve the targeted precision. We observe that the corrections become essential to reliably calculate the corresponding differential distributions especially in regions where the leading-order contribution is absent.

description: The importance of adsorption in water purification and the need to guard against erroneous conclusions often associated with the use of equilibrium adsorption model studies in adsorption systems informed this work. Water purification by adsorption of Congo red (CR) from synthetic aqueous solution to acid treated corncob charcoal (ATCC) was carried out at three different pH values (8.0, 10.5, and 12.0) and at temperatures 10–40 °C. The maximum adsorption capacity of ATCC for CR was 85.8 mg/g at pH 12. The resulting data from the batch adsorption studies were plotted at different temperatures and were fitted to linear form of three isotherm models; Freundlich, Langmuir, and Temkin. Though all three models fitted the experimental data linearly, only Langmuir model was able to account for the observed thermodynamic behavior of the adsorbent–adsorbate systems under the pH conditions. The standard enthalpy values for the adsorption of CR on ATCC at pH 8.0, 10.5, and 12.0 were −5.010 ± 0.312, −7.024 ± 0.440, and −71.426 ± 3.130 kJ mol−1, respectively. The corresponding entropies at pH 8.0, 10.5, and 12.0 were 98.7 ± 1.0, 87.8 ± 1.5, and 129.0 ± 10.5 J mol−1 K−1, respectively. The effect of pH on the thermodynamic quantities were rationalized on the basis of the type of interaction between the CR and the adsorbent. To determine the most suitable model, it was important to juxtapose the observed dependence of adsorption affinity on temperature with the thermodynamic information of the adsorption studies.

 Lemna turionifera ist oft schwer zu erkennen und nur vom Spezialisten sicher anzusprechen. Etwas kleinere Pflanzen als Lemna minor geben jedoch oft einen guten Hinweis auf das Auftreten von Lemna turionifera, die oftmals zwischen Individuen von Spirodela polyrhiza und Lemna minor eingestreut ist. Der Finder (HW) hatte auch lebende Pflanzen aus den Auwaldbereichen bei Steyregg (7752/1) in einem Wasserkübel in Kultur, die über zwei Jahre regelmässig im Herbst die für Lemna turionifera typischen Turionen (Überdauerungsorgane) bildeten und daher ebenfalls mit Sicherheit zu dieser Art zu zählen waren. Wie weit es sich bei den Vorkommen in den Donauauen unterhalb von Linz tatsächlich um einen Neophyten handelt, ist fraglich, da jene Lokalitäten, in denen die Art aufgefunden werden konnte, als die "natürlichsten" des gesamten Umfeldes zu bezeichnen sind.

description: CHORDEILES TEXENSIS (LAWRENCE, 1856)
 Definition
 Previously Chordeiles acutipennis texensis. It is elevated to full species status and is the sister species of Chordeiles acutipennis Hermann, 1783.
 Diagnosis
 Chordeiles texensis is similar morphologically to C. acutipennis, but is noticeably larger in size and paler in plumage, although C. a. littoralis and C. a. micromeris are somewhat intermediate in size between C. texensis and the remaining subspecies of C. acutipennis. Both ND2 and ACO1 I9 show genetic divergence between C. texensis and C. acutipennis, with over 2% divergence in ND2 sequences and 14 homologous substitution events.
 Comments
 Genetic evidence in this study supports the elevation of C. a. texensis to full species status (Fig. 4). The other six subspecies of C. acutipennis remain as members of that species. Further study of the system is recommended, in particular regarding the status of C. a. littoralis and C. a. micromeris.

description: Cette expérience a pour but d’examiner l’effet de la température sur la formation et l’odeur d’un ester obtenu par la réaction entre l’acide acétique et le n-butanol. Cette synthèse mène à la production du butanoate de butyle, un composé au parfum fruité caractéristique. En faisant varier la chaleur appliquée tout en gardant constants les autres paramètres (quantités initiales, temps de réaction, catalyseur utilisé), on cherche à observer comment les conditions thermiques influencent à la fois la quantité de substance formée et la force de l’arôme dégagé. L’analyse des résultats permettra de mieux comprendre le rôle de l’énergie thermique dans le déplacement de l’équilibre chimique ainsi que dans l’expression sensorielle des produits obtenus.

 Über diese kritische Sippe haben wir schon im zweiten Teil dieser Beitragsserie berichtet (STÖHR et al. 2007) und zudem wird sie auch in der Endemitenstudie des Umweltbundesamtes abgehandelt (STÖHR 2009b), so dass sich die nachfolgenden Ausführungen allein auf das Vorkommen in Oberösterreich beschränken können. Myosotis decumbens subsp. kerneri tritt auf der Huttererhöss truppweise an mehreren Stellen in Hochstaudenfluren und am Rand von Latschengebüschen auf und ist morphologisch typisch ausgebildet: Bei sämtlichen untersuchten Pflanzen überragen die Antheren die Kronröhre nicht und die Kronröhre ist durchwegs doppelt so lang wie der Kelch. Dadurch wird die Vermutung von HÖRANDL (1989) bekräftigt, die den einzigen von GRAU (1964) als subsp. variabilis revidierten, aus Oberösterreich stammenden Beleg von der nahen Huterer- und Bärenalpe aufgrund dieser Merkmalskombination eher zur subsp. kerneri stellt. Jedoch nennt GRAU (1964) auch noch einen Beleg der subsp. kerneri von der Wildalpe bei Windischgarsten, die sich unmittelbar benachbart zur Huttererhöss ebenfalls am Nordabfall des Warschenecks befindet. Somit scheint das bei FISCHER et al. (2008) angeführte, fragliche Vorkommen der subsp. kerneri in Oberösterreich nun endgültig gesichert, während hingegen am Auftreten der subsp. variabilis in diesem Bundesland zu zweifeln ist.

description: We derive a simple and general relation between the fidelity of quantum motion, characterizing the stability of quantum dynamics with respect to arbitrary static perturbation of the unitary evolution propagator, and the integrated time auto-correlation function of the generator of perturbation. Surprisingly, this relation predicts the slower decay of fidelity the faster decay of correlations is. In particular, for non-ergodic and non-mixing dynamics, where asymptotic decay of correlations is absent, a qualitatively different and faster decay of fidelity is predicted on a time scale 1/delta as opposed to mixing dynamics where the fidelity is found to decay exponentially on a time-scale 1/delta^2, where delta is a strength of perturbation. A detailed discussion of a semi-classical regime of small effective values of Planck constant is given where classical correlation functions can be used to predict quantum fidelity decay. Note that the correct and intuitively expected classical stability behavior is recovered in the classical limit hbar->0, as the two limits delta->0 and hbar->0 do not commute. In addition we also discuss non-trivial dependence on the number of degrees of freedom. All the theoretical results are clearly demonstrated numerically on a celebrated example of a quantized kicked top.

description: NYCTIDROMUS MERRILLI SENNETT, 1888
 Definition
 Previously N. a. merrilli, and includes individuals assigned to N. a. insularis, N. a. intercedens, and N. a. yucatanensis. It is elevated to full species status and is the sister species of a clade containing N. albicollis and N. derbyanus.
 Diagnosis
 Nyctidromus merrilli is intermediate in size, and the plumage is both lighter and greyer than N. albicollis and N. derbyanus, with a slate-grey coloration on the crown and back being particularly noticeable. There are also conspicuous black patterns on the coverts of N. merrilli, which in both N. albicollis and N. derbyanus tend to be browner. Some individuals in arid areas of Mexico are slightly more reddish in colour, but overall the three named forms within N. merrilli (insularis, merrilli, and yucatanensis) are similar to one another.

description: Produced water is the main waste stream in the oil and gas sector, with significantly greater concentrations of hydrocarbons, heavy metals, and other contaminants. Several works and technologies were developed to reuse the produced water in many applications including drilling and completion fluids. However, in general, a pretreatment is required. According to our knowledge, the reuse of produced water in non-aqueous drilling is still not reported. Therefore, this work proposed the formulation of olefin-based drilling fluids containing between 20-40% of untreated produced water. Through factorial experimental design, the influence of produced water, emulsifier, and viscosifier on the properties of the formulated emulsions was investigated. Our results show that produced water without treatment can be used as an aqueous phase for olefin-based drilling fluids, with the best formulation being the test that has RO/A = 60/40, emulsifier concentration of 14.26 kg/m³ and viscosifier concentration of 2.85 kg/m³. The well-cleaning properties of the proposed formulation were evaluated through numerical simulation in a well with high inclination. The results showed that the hole cleaning was not affected by using untreated produced water in the fluid formulation. The results presented here open a new possibility to reuse produced water in drilling operations without performance loss.

description: We present a comprehensive derivation of a set of universal relations for spin-orbit-coupled Fermi gases in three or two dimension, which follow from the short-range behavior of the two-body physics. Besides the adiabatic energy relations, the large-momentum distribution, the grand canonical potential and pressure relation derived in our previous work for three-dimensional systems {[}Phys. Rev. Lett. 120, 060408 (2018){]}, we further derive high-frequency tail of the radio-frequency spectroscopy and the short-range behavior of the pair correlation function. In addition, we also extend the derivation to two-dimensional systems with Rashba type of spin-orbit coupling. To simply demonstrate how the spin-orbit-coupling effect modifies the two-body short-range behavior, we solve the two-body problem in the sub-Hilbert space of zero center-of-mass momentum and zero total angular momentum, and perturbatively take the spin-orbit-coupling effect into account at short distance, since the strength of the spin-orbit coupling should be much smaller than the corresponding scale of the finite range of interatomic interactions. The universal asymptotic forms of the two-body wave function at short distance are then derived, which do not depend on the short-range details of interatomic potentials. We find that new scattering parameters need to be introduced because of spin-orbit coupling, besides the traditional $s$- and $p$-wave scattering length (volume) and effective ranges. This is a general and unique feature for spin-orbit-coupled systems. We show how these two-body parameters characterize the universal relations in the presence of spin-orbit coupling. This work probably shed light for understanding the profound properties of the many-body quantum systems in the presence of the spin-orbit coupling.

description: Enumerative Geometry is concerned with the number of solutions to a structured system of polynomial equations, when the structure comes from geometry. Enumerative real algebraic geometry studies real solutions to such systems, particularly a priori information on their number. Recent results in this area have, often as not, uncovered new and unexpected phenomena, and it is far from clear what to expect in general. Nevertheless, some themes are emerging. This comprehensive article describe the current state of knowledge, indicating these themes, and suggests lines of future research. In particular, it compares the state of knowledge in Enumerative Real Algebraic Geometry with what is known about real solutions to systems of sparse polynomials.

description: HYDROPSALIS RORAIMAE (CHAPMAN, 1929)
 Definition
 Previously Caprimulgus longirostris roraimae. It is elevated to full species status. It is the sister species
 of H. ruficervix. Together the two species form a clade that is sister to H. longirostris.
 Diagnosis
 Large, very dark, long-billed nightjar with few markings in plumage. It is most similar to H. ruficervix, but is both larger and darker.
 There is genetic divergence in both ND2 and ACO1 I9, with 3.7% divergence in ND2 between H. roraimae and H. ruficervix and 5% divergence between the two and H. longirostris.
 Comments
 Genetic evidence in this study supports elevating the two closely related subspecies of H. longirostris, H. l. roraimae and H. l. ruficervix, to phylogenetic species status, as they are genetically divergent from the remaining taxa assigned to H. longirostris (H. l. atripunctatus, H. l. bifasciatus, H. l. longirostris, and H. l. patagonicus), as well as from one another (Fig. 7). This is in agreement with the suggestions of Cleere (2010), at least regarding H. l. roraimae.

 Bereits vor einigen Jahren (STÖHR et al. 2004a) hatten wir auf das bis dato einzige Rezentvorkommen dieses unverwechselbaren Vergissmeinnichts im Bundesland Salzburg hingewiesen, wobei jene Population im Weidmoos mit dem neu entdeckten, relativ grossen Bestand im Bürmooser Moor früher wohl noch in Verbindung stand, zumal beide Moore durch das Gleissystem der ehemaligen Bockerlbahn verbunden waren. Insofern liegt auch der Schluss nahe, dass sich im Bereich der ehemaligen Bahntrasse hier ev. noch weitere, bislang unbekannte Vorkommen vom Myosotis discolor entdecken lassen.

description: In his article "Transcending Classical Invariant Theory" (J.A.M.S., 1989, Vol 2), Roger Howe established a correspondence between representations of a dual pair of reductive groups. This correspondence is known as Howe's correspondence or local theta correspondence. In my paper "Unitary Representations and Theta Correspondence for Classical Group of Type I"(to appear in J. Func. Anal.), we proved that theta correspondence over the real field preserves unitarity under certain restrictions, generalizing some results of Jian-Shu Li (Invent. Math., Vol 97, 1989). In this paper, we study the compositions of theta correspondences. Under certain favorable conditions, we prove that the composition of theta correspodence yields unitary representations. We call this process quantum induction. Quantum induction resembles parabolic induction in various ways. Some results in this paper were announced at ICM-2002.

PP, Herbarium PP.
Diese, vom Blattwerk an eine kleine Teichrose erinnernde Wasserpflanze wurde im Bundesland Salzburg bisher erst einmal in der Stadt Salzburg angetroffen (PILSL et al. 2008). Während dieses Vorkommen in einem Graben nur aus wenigen Pflanzen bestand, bedeckten die Pflanzen aus dem neuen Vorkommen im Lungau mehrere Quadratmeter eines schlammigen Tümpels. Die Art zeigte sich hier sehr vital und steigt entgegen den Angaben in FISCHER et al. (2008) auch deutlich in die Montanstufe auf. Während das Vorkommen in einem Teich bei Schüttdorf nahe der Stadt Zell am See – obwohl zumindest seit 1964 bestehend (mündl. Mitt. H. SONDEREGGER) – ziemlich sicher angesalbt wurde, ist dies beim Lungauer Bestand nicht so offensichtlich, da sich der Tümpel fernab jeder Siedlung in dem grossen Weidegebiet der Twenger Au befand. Doch auch dieser Bestand wurde höchstwahrscheinlich vor nicht all zu langer Zeit von einem "Naturliebhaber" hier ausgepflanzt und breitet sich nun recht erfolgreich aus.

description: In confined systems, such as the inside of a biological cell, the outer boundary or wall can affect the dynamics of internal particles. In many cases of interest both the internal particle and outer wall are approximately spherical. Therefore, quantifying the wall effects from an outer spherical boundary on the motion of an internal eccentric sphere is very useful. However, when the two spheres are not concentric, the problem becomes non-trivial. In this paper we improve existing analytical methods to evaluate these wall effects and then train a feed-forward artificial neural network within a broader model. The final model generally performed with $\sim 0.001\%$ error within the training domain and $\sim 0.05\%$ when the outer spherical wall was extrapolated to an infinite plane. Through this model, the wall effects of an outer spherical boundary on the arbitrary motion of an internal sphere for all experimentally achievable configurations can now be conveniently and efficiently determined.

ACM vector bundles on prime Fano threefolds and complete intersection Calabi Yau threefolds

Publisher: name: arXiv

Subjects: subject: Algebraic Geometry (math.AG)

description: In this paper we derive a list of all the possible indecomposable normalized rank--two vector bundles without intermediate cohomology on the prime Fano threefolds and on the complete intersection Calabi Yau threefolds, say $V$, of Picard number $ρ=1$. For any such bundle $\E$, if it exists, we find the projective invariants of the curves $C \subset V$ which are the zero-locus of general global sections of $\E$. In turn, a curve $C \subset V$ with such invariants is a section of a bundle $\E$ from our lists. This way we reduce the problem for existence of such bundles on $V$ to the problem for existence of curves with prescribed properties contained in $V$. In part of the cases in our lists the existence of such curves on the general $V$ is known, and we state the question about the existence on the general $V$ of any type of curves from the lists.

Asymptotic behaviour of a solution to a nonlinear equation modelling capillary rise

Subjects: subject: Classical Analysis and ODEs (math.CA)

description: We are concerned with the asymptotics and perturbation analysis of a singular second-order nonlinear ODE that models capillary rise of a fluid inside a narrow vertical tube. We prove the convergence of the exact solution to a unperturbed solution when a nondimensional parameter decrease to zero. Furthermore, we provide an accurate method of approximating the asymptotic solution for large times. Due to the a fact that the nonlinear component in the main equation does not satisfy the Lipschitz continuity condition the methods used to prove the main theorems are nonstandard, require careful analysis, and can be useful in dealing with similar nonlinear ODEs.

 Nachdem erst vor kurzem über ein unbeständig verschlepptes Vorkommen aus dem Gasteinertal berichtet wurde (STÖHR et al. 2007), kann nun das erste segetale und somit typische Vorkommen von Odontites vernus aus dem Land Salzburg vorgestellt werden. Die Art wurde inbesondere im nördlichen Flachgau bereits erwartet, wo rezent noch Ackerbau betrieben wird und mit einer Einstrahlung aus dem benachbarten Innviertel zu rechnen war. Es bleibt abzuwarten, ob sie künftig auch andernorts am Nordrand von Salzburg aufzufinden sein wird.

description: The present work focuses on the phase transition behavior of a thermotropic liquid crystal incorporating a Schiff base having a terminal alkyl chain of 12 carbons, such as, n-dodecyl-2-hydroxy-1-naphthaldimine (SB). Given its interesting molecular structure, the SB was chosen as doping agent for a liquid crystal of cyano-biphenyl type, such as, 4-cyano-4′-n-pentyl-biphenyl (5CB). The study of the guest–host systems, at different concentrations of the solute, was performed using differential scanning calorimetry and UV–visible spectroscopy, equipped with the hot compartment. The fusion and the nematic – isotropic transition temperatures as well as the enthalpies ΔH0 and entropies ΔS0 variations of the 5CB-based systems were determined from their spectral data. The thermal properties and orientational order parameters were also determined for the pure and SB doped 5CB, as well as the activation energy for the guest system. The filamentary texture was observed by polarized light optical microscopy for both the pure and Schiff base-doped 5CB.

description: In this article, FeNi3@MnO2 core–shell nanostructure has been used for the first time to remove Pb(II) and Cd(II) from aqueous solutions by adsorption. The MnO2-coated FeNi3 magnetic nanoparticles were synthesized by the hydrothermal method and characterized by various analytic methods such as X-ray diffraction, Fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscope, transmission electron microscope, and atomic absorption spectrometry. Adsorption parameters such as pH, contact time, adsorbent amount, and initial concentration of metal ions were investigated and optimized. FTIR Spectrum of the nanostructure was used to analyze the adsorption mechanism. FeNi3@MnO2 adsorbent was shown to follow the Langmuir adsorption isotherm and the pseudo-second-order kinetic model. The thermodynamics of adsorption confirmed an endothermic and spontaneous process. The calculated maximum adsorption capacities of the adsorbent for Pb(II) and Cd(II) were 129.2 mg g−1 and 127.8 mg g−1 at room temperature, which confirmed a good adsorption performance, especially for Cd(II). The adsorbent had a good removal efficiency of more than 99% for both metal ions, which was achieved in only 20 minutes.

description: In this study, banana peel powder (BPP) was used to remove carcinogenic crystal violet (CV) dye from aqueous solution. The BPP adsorbent was characterized by Fourier-Transform Infrared (FTIR) spectroscopy and Scanning Electron Microscopy (SEM). In batch sorption experiments, the maximum removal of CV was recorded 93% at optimum levels of operating parameters, i.e., pH 7.0, adsorbent dosage 0.1 g, contact time 10 min, initial adsorbate concentration 90 ppm and temperature 20 C o. The kinetics of the adsorption process was found best to follow the pseudo first order model with high value of R2 (0.9999) and low values of error functions. The Langmuir isotherm model was the best fit with high R2 (0.9552) low values of error models. The plots of Freundlich and D-R isotherms confirmed the feasibility (n = 1.3109 L g−1) and the physisorption nature (Es= 0.1107 kJ mol−1) of the process respectively. The negative values of thermodynamic parameters (ΔG & ΔH) revealed that the adsorption was spontaneous and exothermic in nature respectively. The results of the desorption study showed that 91% of the adsorbent was regenerated. The novelty of the present research is that no work has been reported till date to remove crystal violet dye by using banana peel specifically. The high adsorption and desorption efficiencies (>90%) suggest that BPP possesses characteristics to be used as an effective, fast and low-cost adsorbent for adsorption of CV dye from industrial effluents.HIGHLIGHTSAdsorption technique was employed to remove crystal violet dye by using banana peel powder.The hydroxyl (OH−) & carboxylate (OH−) groups on adsorbent surface provided excellent binding with adsorbate molecules.Equilibrium attainment in 10 min at neutral pH.93% adsorption and 91% desorption.
