Properties of fiber reinforced concrete with latex modification
Creators: name: Xu, Hanfeng
Publisher: name: University of British Columbia
Year: 2009

description: Polymer modified cement-based materials and fiber reinforced cementitious composites are both widely used in civil engineering applications. Both show great advantages, especially in repair and rehabilitation. The work reported here, however, deals with polymer modified fiber reinforced cement based composites (PM-FRC), that is, the combined use of fibers and polymers in the same system. Although they have excellent bonding properties and durability, the relatively low toughness of polymer-modified concretes is still a concern for practical applications under seismic loading or severe service condition, especially for high strength concrete. In this research project, a commercial styrene butadiene latex was used to produce a concrete matrix with a compressive strength ranging from 70 to 80 MPa; a deformed steel fiber and two synthetic fibers (a polypropylene fiber and a blended polypropylene-polyethylene fiber), were incorporated in the matrix to optimize a high performance concrete in terms of flexural toughness. The results show that the high strength concrete made with latex (HSPMC) still failed in a brittle manner, although some ductility was observed. Synergistic effects between the fibers and the latex were observed in most of the composites over a wide range of deflections, as long as suitable polymer dosages were used. However, steel fibers appeared to be more compatible with the latex modified concrete in terms of both load-carrying capacity and toughness. The effects of fiber content and latex dosage are discussed, based on the results of analyses of toughness tests carried out according to ASTM C1018 and JSCE SF4, as well as the post-crack strength (PCS) procedure. It is concluded that a high performance composite with steel fibers and polymers could be a promising material for both structural and repair purposes.

description: Exact solutions of Schroedinger and Pauli equations for charged particles in an external stationary electromagnetic field of an arbitrary configuration are constructed. Green functions of scalar and spinor particles are calculated in this field. The corresponding equations for complex energy of particles bounded by short range potential are deduced. Boundary condition typical for delta - potential is not used in the treatment. Explicit analytical expressions are given for the shift and width of a quasistationary level for different configurations of the external field. The critical value of electric field in which the idea of quasistationary level becomes meaningless is calculated. It is shown that the common view on the stabilizing role of magnetic field concerns only scalar particles.

description: Epilepsy is one of the most common neurological disorders that can be diagnosed through electroencephalogram (EEG), in which the following epileptic events can be observed: pre-ictal, ictal, post-ictal, and interictal. In this paper, we present a novel method for epilepsy detection into two differentiation contexts: binary and multiclass classification. For feature extraction, a total of 105 measures were extracted from power spectrum, spectrogram, and bispectrogram. For classifier building, eight different machine learning algorithms were used. Our method was applied in a widely used EEG database. As a result, random forest and backpropagation based on multilayer perceptron algorithms reached the highest accuracy for binary (98.75%) and multiclass (96.25%) classification problems, respectively. Subsequently, the statistical tests did not find a model that would achieve a better performance than the other classifiers. In the evaluation based on confusion matrices, it was also not possible to identify a classifier that stands out in relation to other models for EEG classification. Even so, our results are promising and competitive with the findings in the literature.

description: For a simple model of chaotic dynamical systems with a large number of degrees of freedom, we find that there is an ensemble of unstable periodic orbits (UPOs) with the special property that the expectation values of macroscopic quantities can be calculated using only one UPO sampled from the ensemble. Evidence to support this conclusion is obtained by generating the ensemble by Monte Carlo calculation for a statistical mechanical model described by a space-time Hamiltonian that is expressed in terms of Floquet exponents of UPOs. This result allows us to interpret the recent interesting discovery that statistical properties of turbulence can be obtained from only one UPO [G. Kawahara and S. Kida, J. Fluid Mech. {\bf 449}, 291 (2001); S. Kato and M. Yamada, Phys. Rev. E {\bf 68}, 025302(R)(2003)].

description: Given the potential economic and environmental benefits from some precision agriculture practices, dissemination of precision farming information as an alternative production management strategy is important. The needs of farmers for precision farming information have been met by various suppliers, including private and public sources. Factors affecting the use of different information sources to obtained precision farming information such as crop consultants, farm dealers, trade shows, Extension, and media are analyzed using a multivariate probit approach that accounts for simultaneous and/or correlation among the different information-source use decisions. Empirical findings suggest that the decision to use private, Extension, and/or Media information sources are correlated. Some factors significantly affecting the use of the information sources analyzed are age, education, and income.

description: Price differences between fed cattle prices in the U.S. and Canada (fed cattle basis) are important for Canadian cattle feeders. Discovery of BSE in Canada in 2003 and changes in exchange rates have made predicting basis difficult. An autoregressive model was estimated to determine factors affecting the basis and effects of governmental policies which addressed issues related to the fed cattle and beef trade. Resumption of beef and live cattle exports improved the basis but implementation of mandatory country of origin labeling in the U.S. adversely affected the basis.

Publisher: name: Unknown
Year: 2009
Subjects: Land Economics/Use

description: The agglomeration bonus literature has not recognized the potential of conditional agreements to overcome the informational requirements, particularly those of landowners, necessary to induce spatially coordinated land conservation. The model presented in this paper shows that the net social benefits produced by a conditional agglomeration bonus program are at least as large as those produced by a traditional uniform subsidy whenever the benefit function exhibits threshold effects and the uniform and CAB subsidies are equal. This result requires no assumptions about the information available to landowners. A regulator’s informational requirements are limited to the shape of the benefit function.

description: We investigate two-dimensional atomic arrays as a platform to modify the electromagnetic environment of individual quantum emitters. Specifically, we demonstrate that control over emission linewidths, resonant frequency shifts, and local enhancement of driving fields is possible due to strong dipole-dipole interactions within ordered, subwavelength atom configurations. We demonstrate that these effects can be used to dramatically enhance coherent dipole-dipole interactions between distant quantum emitters within an atom array. Possible experimental realizations and potential applications are discussed.

description: The demand for organic fresh fruits and vegetable continues to grow at a rate far higher than the rest of the produce industry. The cost of meeting organic certification standards, however, has meant that supply has been slow to adjust. With limited supply, we hypothesize that organic suppliers enjoy more market power in bargaining over their share of the retail-production cost margin for fresh apples. We test this hypothesis using a random parameters, generalized extreme value demand model (mixed logit) combined with a structural model of retail and wholesale pricing that allows conduct to vary by product attributes (organic or non-organic) and time. We find that organic growers do indeed earn a larger share of the total margin than non-organic growers, but this vertical market power is eroding over time as market supply adjusts.

description: Cuprous oxide has been conceived as a potential alternative to traditional organic hole transport layers in hybrid halide perovskite-based solar cells. Device simulations predict record efficiencies using this semiconductor, but experimental results do not yet show this trend. More detailed knowledge about the Cu$_2$O/perovskite interface is mandatory to improve the photoconversion efficiency. Using density functional theory calculations, here we study the interfaces of CH$_3$NH$_3$PbI$_3$ with Cu$_2$O to assess their influence on device performance. Several atomistic models of these interfaces are provided for the first time, considering different compositions of the interface atomic planes. The interface electronic properties are discussed on the basis of the optimal theoretical situation, but in connection with the experimental realizations and device simulations. It is shown that the formation of vacancies in the Cu$_2$O terminating planes is essential to eliminate dangling bonds and trap states. The four interface models that fulfill this condition present a band alignment favorable for photovoltaic conversion. Energy of adhesion, and charge transfer across the interfaces are also studied. The termination of CH$_3$NH$_3$PbI$_3$ in PbI$_2$ atomic planes seems optimal to maximize the photoconversion efficiency.

description: We report on a high-efficiency 461 nm blue light conversion from an external cavity-enhanced second-harmonic generation of a 922 nm diode laser with a quasi-phase-matched KTP crystal (PPKTP). By choosing a long crystal (LC=20 mm) and twice looser focusing (w0=43 $μ$m) than the "optimal" one, thermal lensing effects due to the blue power absorption are minimized while still maintaining near-optimal conversion efficiency. A stable blue power of 234 mW with a net conversion efficiency of eta=75% at an input mode-matched power of 310 mW is obtained. The intra-cavity measurements of the conversion efficiency and temperature tuning bandwidth yield an accurate value d33(461 nm)=15 pm/V for KTP and provide a stringent validation of some recently published linear and thermo-optic dispersion data of KTP.

description: The predicted nature of the candidate redback pulsar 3FGL\,J2039.6$-$5618 was recently confirmed by the discovery of $γ$-ray millisecond pulsations (Clark et al. 2020, hereafter Paper\,I), which identify this $γ$-ray source as \msp. We observed this object with the Parkes radio telescope in 2016 and 2019. We detect radio pulsations at 1.4\,GHz and 3.1\,GHz, at the 2.6ms period discovered in $γ$-rays, and also at 0.7\,GHz in one 2015 archival observation. In all bands, the radio pulse profile is characterised by a single relatively broad peak which leads the main $γ$-ray peak. At 1.4\,GHz we found clear evidence of eclipses of the radio signal for about half of the orbit, a characteristic phenomenon in redback systems, which we associate with the presence of intra-binary gas. From the dispersion measure of $24.57\pm0.03$\,pc\,cm$^{-3}$ we derive a pulsar distance of $0.9\pm 0.2$\,kpc or $1.7\pm0.7$\,kpc, depending on the assumed Galactic electron density model. The modelling of the radio and $γ$-ray light curves leads to an independent determination of the orbital inclination, and to a determination of the pulsar mass, qualitatively consistent to the results in Paper\,I.

description: A catalogue of astrometric (positions, proper motions) and photometric (B, V, R, r', J) data of stars in fields with ICRF objects has been compiled at the Observatory of the National Academy of Sciences of Ukraine and the Kyiv University Observatory. All fields are located in the declination zone from 0 to +30 degrees; the nominal field size is 46' (right ascension) x 24' (declination). The observational basis of this work is 1100 CCD scans down to V=17 mag which were obtained with the Kyiv meridian axial circle in 2001-2003. The catalogue is presented in two versions. The version KMAC1-T contains 159 fields (104 796 stars) and was obtained with reduction to the Tycho2 catalogue. For another 33 fields, due to a low sky density of Tycho2 stars, the reduction was found to be unreliable. Transformation to the ICRF system in the second version of the catalogue (KMAC1-CU) was performed using the UCAC2 and CMC13 catalogues as a reference; it contains 115 032 stars in 192 fields and is of slightly better accuracy. The external accuracy of one catalogue position is about 50-90 mas for V < 15 mag stars. The average error of photometry is better than 0.1 mag for stars down to 16 mag.

description: Quasi-periodically driven quantum systems are predicted to exhibit quantized topological properties, in analogy with the quantized transport properties of topological insulators. We use a single nitrogen-vacancy center in diamond to experimentally study a synthetic quantum Hall effect with a two-tone drive. We measure the evolution of trajectories of two quantum states, initially prepared at nearby points in synthetic phase space. We detect the synthetic Hall effect through the predicted overlap oscillations at a quantized fundamental frequency proportional to the Chern number, which characterizes the topological phases of the system. We further observe half-quantization of the Chern number at the transition between the synthetic Hall regime and the trivial regime, and the associated concentration of local Berry curvature in synthetic phase space. Our work opens up the possibility of using driven qubits to design and study higher-dimensional topological insulators and semi-metals in synthetic dimensions.

description: In this paper, we offer a general equilibrium analysis of the impacts of US and EU biofuel mandates for the global livestock sector. Our simulation boosts biofuel production in the US and EU from 2006 levels to mandated 2015 levels. We show that mandates will encourage crop production in both biofuel and non biofuel producing regions, while reducing livestock and livestock production in most regions of the world. The non-ruminant industry curtails its production more than other livestock industries. The numerical results suggest that the biofuel mandates reduce food production in most regions while they increase crude vegetable oils in almost all regions. Implementing biofuel mandates in the US and EU will increase croplands within the biofuel and non-biofuel producer regions. A large portion of this increase will be obtained from reduced grazing lands. The biofuel producing regions are expected to reduce their coarse grains exports and raise imports of oilseeds and vegetable oils. While all livestock industries use more biofuel byproducts in their animal feed rations, the dairy and other ruminant industry benefit most from the expansion of DDGS. We finally conclude that, while biofuel mandates have important consequences for the livestock industry, they do not harshly curtail these industries. This is largely due to the important role of byproducts in substituting for higher priced feedstuffs. In addition, with relatively inelastic food demands, producers are able to pass much of the price rise on to consumers. In general, US, EU, Meddle East & North Africa, and Russia will experience significant welfare loses due to the combined US and EU mandates, while Brazil, Japan, India, and East Asia are expected to get major gains.

description: The recent concurrent surges of food and commodity prices renew the debate on the causal directions between producer and consumer prices. To address this issue, we utilize the stage of processing system incorporating retail stage beyond crude, intermediate, and finished processing stages of food and employ the method proposed by Toda and Yamamoto (1995) and Dolado and Lütkepohl (1996) of Granger causality tests. The overall results show that consistent with theory of derived demand, the demand-pull mechanisms coexist with the cost-push processes in 1985-2001. However, the upward cost-push pressures dominate the demand-pull mechanism through various transmission channels in 2002-2008.

description: Let $B_1$ be a ball of radius $r_1$ in $S^n(\Hy^n)$, and let $B_0$ be a smaller ball of radius $r_0$ such that $\bar{B_0}\subset B_1$. For $S^n$ we consider $r_1< π$. Let $u$ be a solution of the problem $-\La u =1$ in $\Om := B_1\setminus \bar{B_0}$ vanishing on the boundary. It is shown that the associated functional $J(\Om)$ is minimal if and only if the balls are concentric. It is also shown that the first Dirichlet eigenvalue of the Laplacian on $\Om$ is maximal if and only if the balls are concentric.

description: Зерновое хозяйство является стратегической отраслью аграрной экономики большинства стран мира. Его текущее состояние, эффективность функционирования и перспективы развития зависят от многих факторов как национального, так и глобального уровней. Российская Федерация исторически являлась крупным производителем зерна, а также в последнее время выступает в качестве одного из значимых его экспортёров на мировой рынок. В рамках этой научной статьи авторами проведено исследования современного состояния и повышение эффективности развития зернового хозяйства в крупном зернопроизводящем регионе России – Ростовской области. Основное внимание было уделено следующим вопросам: посевная площадь и валовой сбор злаковых культур в Российской Федерации, реализация зерна по каналам сбыта в Ростовской области в 2016-2019 гг., эффективность производства этого вида продукции в сельскохозяйственных предприятиях рассматриваемого субъекта страны. Были отражены факторы и пути повышения валовых сборов и эффективности выращивания злаковых культур. В условиях увеличения численности населения в мире и изменения природно-климатических условий важным условием повышения эффективности зернового хозяйства зернопроизводящих регионов России является совершенствование механизмов государственной поддержки отрасли, а также развитие инфраструктуры его оптовой торговли и реализации, в том числе в зарубежные страны [Каратаева, Чеха 2020, С. 95-99].

Kinetic Luminosity and Composition of Active Galactic Nuclei Jets

description: We present a new method how to discriminate the matter content of parsec-scale jets of active galactic nuclei. By constraining the kinetic luminosity of a jet from the observed core size at a single very long baseline interferometry frequency, we can infer the electron density of a radio-emitting component as a function of the composition. Comparing this density with that obtained from the theory of synchrotron self-absorption, we can determine the composition. We apply this procedure to the five components in the 3C~345 jet and find that they are likely pair-plasma dominated at 11 epochs out of the total 21 epochs, provided that the bulk Lorentz factor is less than 15 throughout the jet. We also investigate the composition of the 3C~279 jet and demonstrate that its two components are likely pair-plasma dominated at three epochs out of four epochs, provided that their Doppler factors are less than 10, which are consistent with observations. The conclusions do not depend on the lower cutoff energy of radiating particles.

description: The thermal conductivity of the methane hydrate CH4 (5.75 H2O) was measured in the interval 2-140 K using the steady-state technique. The thermal conductivity corresponding to a homogeneous substance was calculated from the measured effective thermal conductivity obtained in the experiment. The temperature dependence of the thermal conductivity is typical for the thermal conductivity of amorphous solids. It is shown that after separation of the hydrate into ice and methane, at 240 K, the thermal conductivity of the ice exhibits a dependence typical of heavily deformed fine-grain polycrystal. The reason for the glass-like behavior in the thermal conductivity of clathrate compounds has been discussed. The experimental results can be interpreted within the phenomenological soft-potential model with two fitting parameters.

description: In this paper we revisit the issue on the impact of public R&D expenditure on US agricultural productivity growth. We estimate a dual cost function using a state-by-year panel data set. We construct the potential R&D “spillins” based on both geographical location and production mix. We also examine the role of the extension service, transportation network, and human capital in the process of technology dissemination. The results indicate that higher levels of local public goods, R&D spillins, extension activities, and an intensive transportation network decrease costs. The contributions to agricultural productivity from all series of R&D spillins are positive even though the social rate of return may differ.

description: The road towards the realization of quantum cascade laser (QCL) frequency combs (QCL-combs) has undoubtedly attracted ubiquitous attention from the scientific community, as these devices promise to deliver all-in-one (i.e. a single, miniature, active devices) frequency comb (FC) synthesizers in a range as wide as QCL spectral coverage itself (from about 4 microns to the THz range), with the unique possibility to tailor their spectral emission by band structure engineering. For these reasons, vigorous efforts have been spent to characterize the emission of four-wave-mixing multi-frequency devices, aiming to seize their functioning mechanisms. However, up to now, all the reported studies focused on free-running QCL-combs, eluding the fundamental ingredient that turns a FC into a useful metrological tool. For the first time we have combined mode-locked multi-frequency QCL emitters with full phase stabilization and independent control of the two FC degrees of freedom. At the same time, we have introduced the Fourier transform analysis of comb emission (FACE) technique, used for measuring and simultaneously monitoring the Fourier phases of the QCL-comb modes. The demonstration of tailored-emission, miniaturized, electrically-driven, mid-infrared/THz coverage, fully-stabilized and fully-controlled QCL-combs finally enables this technology for metrological-grade applications triggering a new scientific leap affecting several fields ranging from everyday life to frontier-research.

description: В статье рассмотрены разные темпы падения производства продукции. За последние годы агропромышленный комплекс в России даже при помощи поддержки государства, свыкся с позицией драйвера экономики и оказался неуязвимым. Постоянный рост заболеваемости в мире привел к кризису в здравоохранении, и все ресурсы, средства были направлены на его решение, увеличение медперсонала и койко-мест в больницах. Во всем мире вводились меры защиты от коронавируса в зависимости от состояния медицины. Из-за сокращения спроса на хмель, вызванного пандемией Covid-19, специалисты ожидают значительного излишка хмеля на мировом рынке – впервые за последние семь лет. Большая часть урожая уже законтрактована, влияние избытка хмеля на его рыночные цены на данный момент довольно сложно предсказать. Активность на спотовом рынке ожидается минимальной – особенно в США, где более 60% хмельников отдано под проприетарные сорта хмеля (выращивать на продажу такие сорта можно только после покупки лицензии).
