description: Chemisorption of CO on the stepped Cu(211) surface is studied within ab-initio density functional theory (DFT) and scanning tunneling microscopy (STM) imaging as well as manipulation experiments. Theoretically we focus on the experimentally observed ordered (2x1) and (3x1) CO-phases at coverages 1/3, 1/2 and 2/3 monolayer (ML). To obtain also information for isolated CO molecules found randomly distributed at low coverages, we also performed calculations for a hypothetical (3x1) phase with 1/3 ML. The adsorption geometry, the stretching frequencies, the work functions and adsorption energies of the CO molecules in the different phases are presented and compared to experimental data. Initially and up to a coverage of 1/2 ML CO adsorbs upright on the on-top sites at step edge atoms. Determining the most favorable adsorption geometry for the 2/3 ML ordered phase turned out to be nontrivial both from the experimental and the theoretical point of view. Experimentally, both top-bridge and top-top configurations were reported, whereby only the top-top arrangement was firmly established. The calculated adsorption energies and the stretching frequencies favor the top-bridge configuration. The possible existence of both configurations at 2/3 ML is critically discussed on the basis of the presently accessible experimental and theoretical data. In addition, we present observations of STM manipulation experiments and corresponding theoretical results, which show that CO adsorbed on-top of a single Cu-adatom, which is manipulated to a location close to the lower step edge, is stronger bound than CO on-top of a step edge atom.

description: Die Arbeit behandelt den heutigen Stand der pleistozänen Stratigraphie vom Gesichtspunkt der geologischen und paläontologischen Grundlagen. Sie macht auf die Möglichkeit der Benützung der klimatischen Schwankungen und ihrer Einwirkung auf die phänotypischen Veränderungen der einzelnen Säugetierarten für ausführliche stratigraphische Gliederung aufmerksam. Diese detaillierte morphologische und metrische Arbeit nimmt natürlich auch eine entsprechende Detailarbeit im Gelände an. Es handelt sich im Grunde um die Möglichkeit der Auswertung der palökologischen Erkenntnisse in der Ekostratigraphie. Das Studium des paläontologischen Materials von diesem Gesichtspunkt ermöglicht nicht nur eine ausführliche Biostratigraphie der Sedimentschichten zu schaffen, sondern es wird auch für mehr detaillierte Schlußfolgerungen, die die Lebensumwelt der einzelnen Zeiträume und die durchlaufenden biotischen und abiotischen Veränderungen betreffen, anwendbar sein.

description: We examine the finite-temperature deconfinement phase transition of (2+1)-dimensional SU(5) Yang-Mills theory via non-perturbative lattice simulations. Unsurprisingly, we find that the transition is of first order, however it appears to be weak. This fits naturally into the general picture of "large" gauge groups having a first order deconfinement transition, even when the center symmetry associated with the transition might suggest otherwise.

description: We study the convergence aspects of the metric on spectral truncations of geometry. We find general conditions on sequences of operator system spectral triples that allows one to prove a result on Gromov-Hausdorff convergence of the corresponding state spaces when equipped with Connes' distance formula. We exemplify this result for spectral truncations of the circle, Fourier series on the circle with a finite number of Fourier modes, and matrix algebras that converge to the sphere.

description: Since 1980 the Institute of Mining and Geosciences of the Technical University of Berlin carried out an educational project at the University of Science and Technology (UST) in Kumasi and the UST School of Mines in Tarkwa, Ghana, Westafrica. Eichmeyer (1) reported about this project already, in which this author did participate. This project of scientific cooperation in the areas of mining and minerals sciences is not the first contact between Germany and Ghana (earlier called Gold Coast or Guinea). At the end of the 17th Century the Brandenburg-Prussians had undertaken mining activities on the Gold Coast already apart from gold-trade. The historical background of these early mining activities will be presented in the light of the then prevailing political and economical conditions. In this context the early mining attempts of other European powers as well as the indigenous mining activities in those days are described. The development of the modern industrial gold mining sector in Ghana was presented by Gosten and Peters (2) elsewhere.

description: We demonstrate dispersive readout of the spin of an ensemble of Nitrogen-Vacancy centers in a high-quality dielectric microwave resonator at room temperature. The spin state is inferred from the reflection phase of a microwave signal probing the resonator. Time-dependent tracking of the spin state is demonstrated, and is employed to measure the T1 relaxation time of the spin ensemble. Dispersive readout provides a microwave interface to solid state spins, translating a spin signal into a microwave phase shift. We estimate that its sensitivity can outperform optical readout schemes, owing to the high accuracy achievable in a measurement of phase. The scheme is moreover applicable to optically inactive spin defects and it is non-destructive, which renders it insensitive to several systematic errors of optical readout and enables the use of quantum feedback.

description: Recent experimental and theoretical work has indicated conditions in which a trapped, low-density Bose gas ought to behave like the 1D delta-function Bose gas solved by Lieb and Liniger. Up to now the theoretical arguments have been based on variational - perturbative ideas or numerical investigations. There are 4 parameters: density, transverse and longitudinal dimensions, and scattering length. In this paper we explicate 5 parameter regions in which various types of 1D or 3D behavior occur. Our discussion is based on a rigorous analysis of the many-body Schroedinger equation. This version of the article is a combination of the earlier 4-page arXiv version and the revised 4-page Physical Review Letters version.

description: Certain closed-universe big-bang/big-crunch cosmological spacetimes may be obtained by analytic continuation from asymptotically AdS Euclidean wormholes, as emphasized by Maldacena and Maoz. We investigate how these Euclidean wormhole spacetimes and their associated cosmological physics might be described within the context of AdS/CFT. We point out that a holographic model for cosmology proposed recently in arXiv:1810.10601 can be understood as a specific example of this picture. Based on this example, we suggest key features that should be present in more general examples of this approach to cosmology. The basic picture is that we start with two non-interacting copies of a Euclidean holographic CFT associated with the asymptotic regions of the Euclidean wormhole and couple these to auxiliary degrees of freedom such that the original theories interact strongly in the IR but softly in the UV. The partition function for the full theory with the auxiliary degrees of freedom can be viewed as a product of partition functions for the original theories averaged over an ensemble of possible sources. The Lorentzian cosmological spacetime is encoded in a wavefunction of the universe that lives in the Hilbert space of the auxiliary degrees of freedom.

The Detection of Cold Dust in Cas A: Evidence for the Formation of Metallic Needles in the Ejecta
Creators: name: Dwek, Eli

Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: Recently, Dunne et al. (2003) obtained 450 and 850 micron SCUBA images of CasA, and reported the detection of 2-4 M_sun of cold, 18K, dust in the remnant. Here we show that their interpretation of the observations faces serious difficulties. Their inferred dust mass is larger than the mass of refractory material in the ejecta of a 10 to 30 M_sun star. The cold dust model faces even more difficulties if the 170 micron observations of the remnant are included in the analysis, decreasing the cold dust temperature to ~ 8K, and increasing its mass to > 20 M_sun. We offer here a more plausible interpretation of their observation, in which the cold dust emission is generated by conducting needles with properties that are completely determined by the combined submillimeter and X-ray observations of the remnant. The needles consist of metallic whiskers with <1% of embedded impurities that may have condensed out of blobs of material that were expelled at high velocities from the inner metal-rich layers of the star in an asymmetric explosion. The needles are collisionally heated by the shocked gas to a temperature of 8K. Taking the destruction of needles into account, a dust mass of only 1E-4 to 1E-3M_sun is needed to account for the observed SCUBA emission. Aligned in the magnetic field, needles may give rise to observable polarized emission. The detection of submillimeter polarization will therefore offer definitive proof for a needle origin for the cold dust emission. Supernovae may still be proven to be important sources of interstellar dust, but the evidence is still inconclusive.

The study is dedicated to creation of complex archaeological map of Old Rus unfortified settlements of two considerable social and historical formations – Galician and Volhynian lands. Such a map was created in Ukraine for the first time. The complex analysis of this sources resulted in the development of the first unified database containing the data regarding the archaeological sites of Galician and Volhynian lands. The database consists of data and its analysis regarding 2695 sites, among which 1959 – unfortified rural settlements, 495 – hilltop fortified settlements, 241 – burials. On the basis of our unified archaeological sites database, the archaeological Settlement Pattern Map was developed. This Map reflects the stages of territory colonization, dominating, the peculiarities of rural settlements’ functioning on the considerable territory that includes rivers’ Prut, Dnister, Horyn’, Styr, Western Buh, and Pryp’yat’ basins. The dynamics of sites’ development in the certain micro–regions on the every chronological stage — 10th, 11th, 12th–13th cent. – was analyzed. As a result, the complex archaeological geoinformation system of Galician and Volhynian lands’ rural sites was developed.

description: It is common for scale-dependent analysis of stochastic data to use the increment $Δ(t,r) = ξ(t+r) - ξ(t)$ of a data set $ξ(t)$ as a stochastic measure, where $r$ denotes the scale. For joint statistics of $Δ(t,r)$ and $Δ(t,r')$ the question how to nest the increments on different scales $r,r'$ is investigated. Here we show that in some cases spurious correlations between scales can be introduced by the common left-justified definition. The consequences for a Markov process are discussed. These spurious correlations can be avoided by an appropriate nesting of increments. We demonstrate this effect for different data sets and show how it can be detected and quantified. The problem allows to propose a unique method to distinguish between experimental data generated by a noiselike or a Langevin-like random-walk process, respectively.

description: Complete theoretical understanding of the most complex superconductors requires a detailed knowledge of the symmetry of the superconducting energy-gap $Δ_\mathbf{k}^α$, for all momenta $\mathbf{k}$ on the Fermi surface of every band $α$. While there are a variety of techniques for determining $|Δ_\mathbf{k}^α|$, no general method existed to measure the signed values of $Δ_\mathbf{k}^α$. Recently, however, a new technique based on phase-resolved visualization of superconducting quasiparticle interference (QPI) patterns centered on a single non-magnetic impurity atom, was introduced. In principle, energy-resolved and phase-resolved Fourier analysis of these images identifies wavevectors connecting all k-space regions where $Δ_\mathbf{k}^α$ has the same or opposite sign. But use of a single isolated impurity atom, from whose precise location the spatial phase of the scattering interference pattern must be measured is technically difficult. Here we introduce a generalization of this approach for use with multiple impurity atoms, and demonstrate its validity by comparing the $Δ_\mathbf{k}^α$ it generates to the $Δ_\mathbf{k}^α$ determined from single-atom scattering in FeSe where $s_{\pm}$ energy-gap symmetry is established. Finally, to exemplify utility, we use the multi-atom technique on LiFeAs and find scattering interference between the hole-like and electron-like pockets as predicted for $Δ_\mathbf{k}^α$ of opposite sign.
Radiative Mixing Layers: Insights from Turbulent Combustion

description: Radiative mixing layers arise wherever multiphase gas, shear, and radiative cooling are present. Simulations show that in steady state, thermal advection from the hot phase balances radiative cooling. However, many features are puzzling. For instance, hot gas entrainment appears to be numerically converged despite the scale-free, fractal structure of such fronts being unresolved. Additionally, the hot gas heat flux has a characteristic velocity $v_{\rm in} \approx c_{\rm s,cold} (t_{\rm cool}/t_{\rm sc,cold})^{-1/4}$ whose strength and scaling are not intuitive. We revisit these issues in 1D and 3D hydrodynamic simulations. We find that over-cooling only happens if numerical diffusion dominates thermal transport; convergence is still possible even when the Field length is unresolved. A deeper physical understanding of radiative fronts can be obtained by exploiting parallels between mixing layers and turbulent combustion, which has well-developed theory and abundant experimental data. A key parameter is the Damköhler number ${\rm Da} = τ_{\rm turb}/t_{\rm cool}$, the ratio of the outer eddy turnover time to the cooling time. Once ${\rm Da} > 1$, the front fragments into a multiphase medium. Just as for scalar mixing, the eddy turnover time sets the mixing rate, independent of small scale diffusion. For this reason, thermal conduction often has limited impact. We show that $v_{\rm in}$ and the effective emissivity can be understood in detail by adapting combustion theory scalings. Mean density and temperature profiles can also be reproduced remarkably well by mixing length theory. These results have implications for the structure and survival of cold gas in many settings, and resolution requirements for large scale galaxy simulations.

description: In the Dominican Republic, the area planted with coffee is 132,500 ha which produces an annual harvest of 36,636,364 kg through the efforts of more than 50,000 coffee farmers. Since 1997, the broca (Hypothenemus hampei) pest has infested the coffee fields in the country and has reduced crop yield and quality. The objectives of this study were to evaluate the influence of altitude and harvest period on the incidence of the broca incidence and on coffee bean grain quality. The experimental design was a completely randomized design with a factorial arrangement with 4 replicates. The twelve treatment combinations were formed from four altitudes (400-500, 600-700, 850-950 and 1000- 1100 meters) and three harvest periods (November, December and January). The variables were crop management, percentage of infected grains, and commercial quality of the beans. The results showed that from 78.4% to 100% of the farmers controlled the shade at 850-950 meters of altitude while 74.75% did so at 400-500 meters of altitude. The higher incidences (22.33 % and 20.00 %) of infected beans were at 400-500 and 600- 700 meters of altitude, respectively. The lineal regression analysis showed an inverse relationship between altitude and percentage of infected grains. Moreover, this analysis showed a direct relationship between altitude and bean quality AAA, but an inverse relationship with quality AA and A. The highest percentage of beans with quality AAA (69.44 %) and AA (52.61 %) were at 1000 -1100, and 400-500 meters of altitude, respectively. The data suggest that altitude affects the yield and quality of coffee beans.
Pulsed fraction of super-critical column accretion flows onto neutron stars: modeling of ultraluminous X-ray pulsars

description: We calculate the pulsed fraction (PF) of the super-critical column accretion flows onto magnetized neutron stars (NSs), of which the magnetic axis is misaligned with the rotation axis, based on the simulation results by Kawashima et al.(2016, PASJ, 68, 83). Here, we solve the geodesic equation for light in the Schwarzschild spacetime in order to take into account the light bending effect. The gravitational redshift and the relativistic doppler effect from gas motions of the accretion columns are also incorporated. The pulsed emission appears since the observed luminosity, which exceeds the Eddington luminosity for the stellar-mass black holes, periodically changes via precession of the column caused by the rotation of the NS. The PF tends to increase as $θ_{\rm obs}$ approaching to $θ_{\rm B}$, where $θ_{\rm obs}$ and $θ_{\rm B}$ are the observer's viewing angle and the polar angle of the magnetic axis measured from the rotation axis. The maximum PF is around 50 %. Also, we find that the PF becomes less than 5 % for $θ_{\rm obs} \lesssim 5^\circ$ or for $θ_{\rm B} \lesssim 5^\circ$. Our results are consistent with observations of ultraluminous X-ray pulsars (ULXPs) with few exceptions, since the ULXPs mostly exhibit the PF of $\lesssim$ 50 %. Our present study supports the hypothesis that the ULXPs are powered by the super-critical column accretion onto NSs.

'Ubon Stylo' was planted in August 2007 at the Isabela Substation of the Agricultural Experimental Station, University of Puerto Rico. The aftermath (first harvest) was 100 days after establishment. The experimental design was a complete randomized block with four replicates for the seeding rates. Variables assessed were: 1) Ubon Stylo and weed density (number of emerged plants in 1 m2) and dry matter yield (DMY; kg/ha). There were significant differences (p<0.05) between plant density of Ubon Stylo and weed species. Ubon Stylo plant density averaged 82 plants/m2 determined at the highest seeding rate (20 kg/ha). There was significant difference in DMY among seeding rates. Lowest DMY yield was observed at low seeding rate of 5 kg/ha (2758 kg/ha), but no difference was observed between the 10 (5,200 kg/ha) and 15 kg/ha (4752). Planting at a high rate 20 kg/ha (6100 kg/ha), although statistically significant from other rates, does not justify seed costs. It is concluded that seeding rates of Ubon Stylo between 10 and 15 kg/ha provides adequate plant densities and excellent DMY.

A multifunctional protein : Phosphoglucose isomerase / autocrine motility factory / neuroleukin
Creators: name: Y, Nathalie

description: Phosphoglucose isomerase (PGI) is a glycolytic enzyme that moonlights as a cellular cytokine. The protein is also known as autocrine motility factor (AMF), neuroleukin and maturation factor. PGI/AMF interaction with its receptor interaction is pH-dependent. Indeed, at neutral pH, PGI/AMF binds its receptor AMFR at the cell surface and can be endocytosed via two different pathways: caveolae/raft-dependent endocytosis to the smooth ER or clathrin-dependent endocytosis to multivesicular bodies (MVBs). Internalized PGI/AMF can recycle from MVBs to the plasma membrane where it can undergo further rounds of endocytosis and recycling. Recycling receptor-ligand complexes can also be sequestered via stable association with FN fibrils. Recent data show that, at acid pH, endocytosis is inhibited and PGI/AMF binds directly to FN fibrils or to HS. Heparan sulfate proteoglycans, when expressed on the surface of cells, modulate the actions of a large number of extracellular ligands while fibronectin is involved in many cellular processes such as tissue repair and cell migration/adhesion. However, the mechanisms that regulate PGI/AMF binding to its receptors still remain unclear. PGI/AMF cytokine activity, associated with several diseases, has been reported in rheumatoid synovial fluid and its deposition on synovial surfaces and ability to induce an autoimmune response in rheumatoid arthritis (RA) identified it as a possible autoantigen different from normal circulating PGI/AMF. However, more recent manuscripts have questioned the prevalence of an autoimmune response to PGI in RA . In this study, recombinant PGI constructs were used to characterize PGI interactions and functions. We demonstrate that PGI behaves differently after N or C-terminal residue additions. Our data also suggest that monomerization but not enzymatic activity is necessary to induce cell motility at neutral pH. The putative function of PGI in RA was assessed and using the recombinant PGI constructs and PGI autoantibodies was found to be species and conformation-dependant.

description: The degree of weathering in natural stones on buildings and sculptures has been determined for many years in numerous cases by means of ultrasonic measurements. Conclusions concerning the strength of the rock and the type of weathering can thus be drawn. This relationship has not been established for all rock types. Most of the progress utilizing this method has been made in the analysis of marbles, where an increasing degree of weathering shows lower ultrasonic velocities. In the present study, four Carrara marble samples showing similar rock fabrics, but with respect to weathering exhibit considerable differences are investigated. Porosity varies between 0.2 vol. % and ca. 2.4 vol. %, whereby with increasing porosity the pore radii changes as well. Parallel to this the ultrasonic velocities change in dry samples from about 5.5 to 1.6 km/s, respectively. Model calculations reveal that the velocity reduction is caused by cracks with an extremely small aspect ratio of about 0.005 or even less. After a specific loss of strength, however, solution processes can become active, which modify the microcracks and generate an opposite trend. In the process a strong porosity increase correlates to a relatively small velocity reduction. With the presence of water the Vp porosity weathering relationship experiences a considerable modification. Parallel to the reduction of the ultrasonic velocities, it was determined that the mechanical strength (compressive strength, flexural strength, etc.) as well as the static Young’s modulus is reduced almost equally by a progressive advancement of the weathering front. In one case study dealing with tensile strengths, it was clearly documented how tensile cracks develop and propagate in dependence of the rock fabric. The rock mechanical and ultrasonic velocity data were used for stability assessments applied to the marble statuaries from the Schlossbrücke in Berlin. Stability assessments of the sculpture group 4 reveal that some critical parts must be replaced due to safety reasons.

description: Finding alternative avenues for disposal of food manufacturing waste has become important in the Caribbean Region due to increasing populations, concerns about environmental pollution, increased growth in the manufacturing sector, as well as limited land availability for disposal. Two field trials were conducted on a mixed loamy isohyperthermic Fluventic Eutropepts in the dry (Trial 1) and wet (Trial 2) seasons to evaluate the effect of adding food processing wastewater residuals on the crop productivity of Tanner grass (Brachiaria arrecta). The wastewater residual was compared to inorganic sources of nitrogen (N) and phosphorus (P) from urea and triple superphosphate, respectively at 0, 50 and 200 kg N/ha and 0, 50 and 100 kg P/ha respectively in a randomized complete block design. In the dry season, the inorganic Ν resulted in a Tanner grass dry matter (DM) yield of 4357 kg/ha, which was significantly (P<0.05) higher than that resulting from the wastewater residual Ν (1835 kg/ha). However, similar yields of 2898 kg/ha and 2610 kg/ha for inorganic Ν and wastewater residual Ν respectively were obtained in the wet season. The wastewater residual applied at 200 kg N/ha with no supplemented Ρ resulted in a higher (P<0.05) DM yield of 2875 kg/ha compared to the yields of 1535 kg/ha from the unfertilized control in the wet season. Tanner grass dry matter yields for both seasons were higher in response to application of the wastewater residual at 50 and 200 kg N/ha versus the unfertilized control. Food processing wastewater residual can be used in pasture production as an organic soil amendment as an alternative to disposal since it is capable of supporting plant growth.
Zur postglazialen Sedimentationsgeschichte des Großen Jasmunder Boddens, südliche Ostsee

description: In der vorliegenden Arbeit wird die postglaziale Entwicklungsgeschichte des Großen Jasmunder Boddens (südliche Ostsee) anhand der Ergebnisse von stratigraphisch-geochemischen Untersuchungen an zwei Sedimentkernen aus dem Gewässer dargestellt. Die untersuchten Sedimentkerne erfassen einen Zeitraum zwischen dem Älteren Atlantikum und der Gegenwart. Der mit dem Einsetzen der Litorina-Transgression verbundene Anstieg des Meeresspiegels im Untersuchungsgebiet führte im Zentralteil des heutigen Gewässers zunächst zur Torfbildung und zur Ablagerung einer Organomudde. Diese organisch-reichen Sedimente wurden mit dem weiteren Anstieg des Meeresspiegels überflutet und von marinen Sedimenten überlagert. Die mit dem Aufbau einer Nehrung verbundene Abriegelung der Meeresbucht bewirkte im Subatlantikum eine Aussüßung des Gewässers. Die Entwicklungsgeschichte des Boddens spiegelt sich in der Geochemie der Sedimente wider. Die C(org)/N-Verhältnisse in den marinbrackischen Sedimenten deuten zusammen mit den δ13C- und δ15N-Werten auf die Dominanz autochthonen organischen Materials mit hohen Anteilen von aquatischen Makrophyten. In den rezenten Sedimenten nimmt der Planktonanteil auf Kosten der Makrophyten zu. Die C(org)/S-Verhältnisse der Sedimente fallen in die für Süßwassermilieus typische Größenordnung. Die Pyritbildung in den Sedimenten des Großen Jasmunder Boddens ist sulfatlimitiert. Der Zusammenhang zwischen Akkumulationsraten organischen Kohlenstoffs (C(org)-AR) und Sedimentakkumulationsraten (SAR) wird deutlich von der Menge, der Zusammensetzung und den ablaufenden Abbauprozessen organischer Substanz bestimmt. Erhöhte Produktivität resultiert dabei aufgrund des polymiktischen Charakters des Gewässers nicht unmittelbar in höheren Sedimentationsraten. Die Akkumulationsraten von organischem Kohlenstoff, Stickstoff und biogenem Opal nehmen ab etwa 1400 BP zur Gegenwart hin deutlich zu. Dieser Trend ist für die Akkumulationsraten von Kalziumkarbonat nicht erkennbar. Das deutet darauf hin, daß der Anteil des von autochthonen karbonatbildenden Organismen herstammenden Kalziumkarbonateintrags gegenüber allochthonen Einträgen gering ist.

description: Purpose: We present image classifiers based on Dense Convolutional Networks and transfer learning to classify chest X-ray images according to three labels: COVID-19, pneumonia and normal. Methods: We fine-tuned neural networks pretrained on ImageNet and applied a twice transfer learning approach, using NIH ChestX-ray14 dataset as an intermediate step. We also suggested a novelty called output neuron keeping, which changes the twice transfer learning technique. In order to clarify the modus operandi of the models, we used Layer-wise Relevance Propagation (LRP) to generate heatmaps. Results: We were able to reach test accuracy of 100% on our test dataset. Twice transfer learning and output neuron keeping showed promising results improving performances, mainly in the beginning of the training process. Although LRP revealed that words on the X-rays can influence the networks' predictions, we discovered this had only a very small effect on accuracy. Conclusion: Although clinical studies and larger datasets are still needed to further ensure good generalization, the state-of-the-art performances we achieved show that, with the help of artificial intelligence, chest X-rays can become a cheap and accurate auxiliary method for COVID-19 diagnosis. Heatmaps generated by LRP improve the interpretability of the deep neural networks and indicate an analytical path for future research on diagnosis. Twice transfer learning with output neuron keeping improved performances.

description: Three tillage methods, conventional till, minimum till and deep till versus no till and their respective interaction with three fertilizer levels (0, lx and 2x the recommended amount) were evaluated in a crop rotation that included yam (.Dioscorea alata L.), eggplant (Solanum melongena L.), bean (Phaseolus vulgaris L.) and corn (Zea mays L.). The experiment was established at three ecologically different locations with three different soil orders: Ultisol, Oxisol and Vertisol. Yam, the first crop in the rotation, was planted after soil preparation according to the treatments. The crops that followed in the rotation were planted no till in the same plots. A fifth treatment, in which all crops in the rotation were planted under conventional tillage, was used as a check. Yield response of the rotation crops varied with location. Yam yields in the no till plots were significantly lower than in the conventional till plots in the Ultisol and Vertisol soils, but not in the Oxisol soil. Response to fertilizer was observed only in the Oxisol. Yield response of eggplant with respect to the tillage treatments was similar to that observed for yams, thus suggesting that there was a residual effect of tillage. For the bean and corn crops, the third and fourth crops of the rotation, the residual effect of the tillage practices performed at the beginning of the rotation cycle was little if any.

description: Venomous snakes are among the world’s most effective predators. Their unique feeding style uses fangs to inject venom, immobilising, killing, and finally dissolving their prey. Venomous snakes show differences in body shape, feeding behaviour and fang anatomy. To investigate how this affects each snake’s ability to catch and kill prey, a combination of live behaviour experiments, microCT scanning and 3D computer engineering was used. The results enable us to predict the diet of lesser-known and extinct snakes, determine unexpected drivers of strike speed, and see how new fangs are connected to the venom duct.
