description: Attempts to separate the power of classical and quantum models of computation have a long history. The ultimate goal is to find exponential separations for computational problems. However, such separations do not come a dime a dozen: while there were some early successes in the form of hidden subgroup problems for abelian groups--which generalize Shor's factoring algorithm perhaps most faithfully--only for a handful of non-abelian groups efficient quantum algorithms were found. Recently, problems have gotten increased attention that seek to identify hidden sub-structures of other combinatorial and algebraic objects besides groups. In this paper we provide new examples for exponential separations by considering hidden shift problems that are defined for several classes of highly non-linear Boolean functions. These so-called bent functions arise in cryptography, where their property of having perfectly flat Fourier spectra on the Boolean hypercube gives them resilience against certain types of attack. We present new quantum algorithms that solve the hidden shift problems for several well-known classes of bent functions in polynomial time and with a constant number of queries, while the classical query complexity is shown to be exponential. Our approach uses a technique that exploits the duality between bent functions and their Fourier transforms.

description: Using recently published, high-precision pi+pi- cross section data by the BABAR experiment from the analysis of e+e- events with high-energy photon radiation in the initial state, we reevaluate the lowest order hadronic contribution a_mu[had,LO] to the anomalous magnetic moment of the muon. We employ newly developed software featuring improved data interpolation and averaging, more accurate error propagation and systematic validation. With the new data, the discrepancy between the e+e- and tau-based results for the dominant two-pion mode reduces from previously 2.4 sigma to 1.5 sigma in the dispersion integral, though significant local discrepancies in the spectra persist. We obtain for the e+e- based evaluation amu[had,LO] = (695.5 +- 4.1) 10^-10, where the error accounts for all sources. The full Standard Model prediction of a_mu differs from the experimental value by 3.2 sigma.

description: Recent developments in laser-excited photoemission electron microscopy (laser-PEEM) advance the visualization of electronic nematicity and nematic domain structures in iron-based superconductors. In FeSe and BaFe$_2$(As$_{0.87}$P$_{0.13}$)$_2$ superconductors, it has been reported that the thickness of the electronic nematic domain walls is unexpectedly long, leading to the formation of mesoscopic nematicity wave [T. Shimojima $\textit{et al.}$, Science $\textbf{373}$ (2021) 1122]. This finding demonstrates that the nematic coherence length $ξ_{\rm nem}$ can be decoupled from the lattice domain wall. Here, we report that the electronic domain wall thickness shows a distinct variation in related materials: it is similarly long in FeSe$_{0.9}$S$_{0.1}$ whereas it is much shorter in undoped BaFe$_2$As$_2$. We find a correlation between the thick domain walls and the non-Fermi liquid properties of normal-state resistivity above the nematic transition temperature. This suggests that the nematic coherence length can be enhanced by underlying spin-orbital fluctuations responsible for the anomalous transport properties.

Graph fusion algebras of WLM(p,p')

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider the W-extended logarithmic minimal model WLM(p,p'). As in the rational minimal models, the so-called fundamental fusion algebra of WLM(p,p') is described by a simple graph fusion algebra. The fusion matrices in the regular representation thereof are mutually commuting, but in general not diagonalizable. Nevertheless, we show that they can be brought simultaneously to block-diagonal forms whose blocks are upper-triangular matrices of dimension 1, 3, 5 or 9. The directed graphs associated with the two fundamental modules are described in detail. The corresponding adjacency matrices share a complete set of common generalized eigenvectors organized as a web constructed by interlacing the Jordan chains of the two matrices. This web is here called a Jordan web and it consists of connected subwebs with 1, 3, 5 or 9 generalized eigenvectors. The similarity matrix, formed by concatenating these vectors, simultaneously brings the two fundamental adjacency matrices to Jordan canonical form modulo permutation similarity. The ranks of the participating Jordan blocks are 1 or 3, and the corresponding eigenvalues are given by 2cos(jπ/n) where j=0,...,n and n=p,p'. For p>1, only some of the modules in the fundamental fusion algebra of WLM(p,p') are associated with boundary conditions within our lattice approach. The regular representation of the corresponding fusion subalgebra has features similar to the ones in the regular representation of the fundamental fusion algebra, but with dimensions of the upper-triangular blocks and connected Jordan-web components given by 1, 2, 3 or 8. Some of the key results are illustrated for W-extended critical percolation WLM(2,3).

description: Cold atoms in an optical lattice execute Bloch-Zener oscillations when they are accelerated. We have performed a theoretical investigation into the case when the optical lattice is the intra-cavity field of a driven Fabry-Perot resonator. When the atoms oscillate inside the resonator, we find that their back-action modulates the phase and intensity of the light transmitted through the cavity. We solve the coupled atom-light equations self-consistently and show that, remarkably, the Bloch period is unaffected by this back-action. The transmitted light provides a way to observe the oscillation continuously, allowing high precision measurements to be made with a small cloud of atoms.

description: Carbon-doping of GaN layers with thickness in the mm-range is performed by hydride vapor phase epitaxy. Characterization by optical and electrical measurements reveals semi-insulating behavior with a maximum of specific resistivity of 2 × 1010 Ω cm at room temperature found for a carbon concentration of 8.8 × 1018 cm−3. For higher carbon levels up to 3.5 × 1019 cm−3, a slight increase of the conductivity is observed and related to self-compensation and passivation of the acceptor. The acceptor can be identified as CN with an electrical activation energy of 0.94 eV and partial passivation by interstitial hydrogen. In addition, two differently oriented tri-carbon defects, CN-a-CGa-a-CN and CN-a-CGa-c-CN, are identified which probably compensate about two-thirds of the carbon which is incorporated in excess of 2 × 1018 cm−3. © 2019 The Authors.

Frontier conflict in Van Diemen's Land
Creators: name: Clements, NP
Publisher: name: University Of Tasmania
Year: 2023

description: Eastern Van Diemen's Land was the site of the most intense frontier conflict in Australia. What is known today as the Black War (1824-1831) produced at least 450 colonial casualties and all but wiped out the Aborigines. This thesis examines the attitudes and experiences of the men, women and children ‚Äö-black and white ‚Äö- who were involved. It asks: How did each side perceive the other? What motivated them to violence? What tactics did they employ? How did each side cope with being hunted? And what was the emotional cost? These questions are long overdue. Historians have almost invariably examined the War from the 'top down', poring over ethical and legal questions. These are important concerns for posterity, but they were not those of Aborigines or frontier colonists. Their beliefs, desires, behaviours and emotions constituted the human side of the Black War, and they have been all but ignored. The alternating white/black chapters of this thesis juxtapose the perspectives of colonists and Aborigines. Close attention has been paid to the minutiae of frontier life, which were a chief determinant of behaviour and experience. Drawing on a range of methods, the cultures, voices and actions of participants have been sifted from Tasmania's vast archive. To verify and contextualise this anecdotal evidence, a catalogue of all recorded violent incidents and their details has been appended. The Black War was a guerrilla war consisting of hundreds of ambushes on Aborigines' camps by night, and on colonists' huts by day. Exceptions to this day/night pattern were rare, which meant the War was fought and experienced according to a solar rhythm. A key source of white violence was sex deprivation. European women being extremely scarce, so frontiersmen sought black females any way they could. Later, revenge and self-defence also motivated them to kill. Aborigines attacked whites to resist invasion, avenge mounting insults, and to plunder food and blankets. Both lived in suffocating fear, terrified of their enigmatic foes. Likewise, both saw themselves victims, and both felt justified in victimising the other. It was not a battle between good and evil, but a struggle between desperate human beings. This thesis challenges a range of long-standing assumptions about the War, while also providing new evidence and perspectives. Its attitudinal and experiential analysis illuminates the War in a new light, while its quantitative analysis indicates a larger-scale conflict than previously imagined, with distinct and telling patterns of violence. Moreover, a systematic examination of frontier conflict at the ground level and from both is all but untried in Australian history.

description: We study the distribution of the Schmidt coefficients of the reduced density matrix of a quantum system in a pure state. By applying general methods of statistical mechanics, we introduce a fictitious temperature and a partition function and translate the problem in terms of the distribution of the eigenvalues of random matrices. We investigate the appearance of two phase transitions, one at a positive temperature, associated to very entangled states, and one at a negative temperature, signalling the appearance of a significant factorization in the many-body wave function. We also focus on the presence of metastable states (related to 2-D quantum gravity) and study the finite size corrections to the saddle point solution.

description: We examine how nuclear masses are related to the density dependence of the symmetry energy. Using a macroscopic nuclear model we calculate nuclear masses in a way dependent on the equation of state of asymmetric nuclear matter. We find by comparison with empirical two-proton separation energies that a smaller symmetry energy at subnuclear densities, corresponding to a larger density symmetry coefficient L, is favored. This tendency, which is clearly seen for nuclei that are neutron-rich, nondeformed, and light, can be understood from the property of the surface symmetry energy in a compressible liquid-drop picture.

description: We numerically study the thermoelectric transports of Dirac fermions in graphene in the presence of a strong magnetic field and disorder. We find that the thermoelectric transport coefficients demonstrate universal behavior depending on the ratio between the temperature and the width of the disorder-broadened Landau levels(LLs). The transverse thermoelectric conductivity $α_{xy}$ reaches a universal quantum value at the center of each LL in the high temperature regime, and it has a linear temperature dependence at low temperatures. The calculated Nernst signal has a peak at the central LL with heights of the order of $k_B/e$, and changes sign near other LLs, while the thermopower has an opposite behavior, in good agreement with experimental data. The validity of the generalized Mott relation between the thermoelectric and electrical transport coefficients is verified in a wide range of temperatures.

description: In a recent FTC by Tremblay {\sl et al} (2009 {\sl J. Phys. A: Math. Theor.} {\bf 42} 205206), it has been conjectured that for any integer value of $k$, some novel exactly solvable and integrable quantum Hamiltonian $H_k$ on a plane is superintegrable and that the additional integral of motion is a $2k$th-order differential operator $Y_{2k}$. Here we demonstrate the conjecture for the infinite family of Hamiltonians $H_k$ with odd $k \ge 3$, whose first member corresponds to the three-body Calogero-Marchioro-Wolfes model after elimination of the centre-of-mass motion. Our approach is based on the construction of some $D_{2k}$-extended and invariant Hamiltonian $\chh_k$, which can be interpreted as a modified boson oscillator Hamiltonian. The latter is then shown to possess a $D_{2k}$-invariant integral of motion $\cyy_{2k}$, from which $Y_{2k}$ can be obtained by projection in the $D_{2k}$ identity representation space.

description: À cause des conflits prolongés, des millions de personnes en République Démocratique du Congo (RDC) ont fui leur foyer pour chercher un refuge ailleurs. On note ce phénomène surtout dans l’Est du pays. La majorité de personnes déplacées à l’intérieur du pays (PDI) se réfugient dans des villes et d’autres communautés locales plutôt que dans des camps des déplacés. Bukavu, la capitale de la province du Sud-Kivu, en est un exemple. Ces dernières années, Bukavu a connu une croissance rapide en raison de l’afflux de personnes déplacées et d’autres migrants, principalement en provenance des territoires voisins. Pourtant, dans la ville, les personnes déplacées se débrouillent en grande partie par elles-mêmes, et nombre d’entre elles connaissent une précarité socio-économique. La connectivité est l’un des moyens par lesquels les PDI peuvent améliorer leur situation. Les premières et plus importantes connexions que les personnes déplacées mobilisent à leur arrivée sont les liens familiaux. C’est à partir de là qu’elles commencent une “chaîne de connectivité” sur la voie de l’intégration locale. Nos recherches à Bukavu montrent que de nombreuses personnes dépendent des autres pour être ou devenir autonomes : Elles obtiennent l’accès à l’emploi, au logement ou aux services de base grâce à leurs réseaux.

description: It is well known that inverse semigroups are closely related to étale groupoids. In particular, it has recently been shown that there is a (non-functorial) equivalence between localic étale groupoids, on one hand, and complete and infinitely distributive inverse semigroups (abstract complete pseudogroups), on the other. This correspondence is mediated by a class of quantales, known as inverse quantal frames, that are obtained from the inverse semigroups by a simple join completion that yields an equivalence of categories. Hence, we can regard abstract complete pseudogroups as being essentially ``the same'' as inverse quantal frames, and in this paper we exploit this fact in order to find a suitable replacement for inverse semigroups in the context of open groupoids that are not necessarily étale. The interest of such a generalization lies in the importance and ubiquity of open groupoids in areas such as operator algebras, differential geometry and topos theory, and we achieve it by means of a class of quantales, called open quantal frames, which generalize inverse quantal frames and whose properties we study in detail. The resulting correspondence between quantales and open groupoids is not a straightforward generalization of the previous results concerning étale groupoids, and it depends heavily on the existence of inverse semigroups of local bisections of the quantales involved.

description: When a hazardous event occurs, such as an earthquake, eruption, storm, tsunami or landslide, there are often delays in understanding the severity and extent of the hazard and impacts. There are gaps in loss databases that inform forecast and warning systems, monitoring networks have gaps and there is limited capacity for officials to quickly visit every site to assess the damage. This results in delays in response, a reliance on media for situational awareness and a lack of information to inform response decisions and messaging. There are also gaps in loss databases, which help inform future risk management decisions and impact-based forecast and warning systems. We conducted 16 interviews with stakeholder agencies to understand their challenges in accessing real-time hazard and impact information. As a potential solution, we scoped out developing a real-time hazard and impact visualisation tool for Aotearoa New Zealand. We also aligned with other projects to collect data on the public’s willingness to submit observations (N = 4725, through an online survey) and to understand user needs for risk modelling outputs (six workshops and a survey, N = 145). We found that there is a need to connect existing hazard and impact data from multiple agencies, including monitoring data, forecasts and warnings and real-time risk/impact model outputs. Additionally, more crowdsourced observations would be beneficial, despite the associated data quality challenges. There was support for an online viewer application to be co-developed, as well as making data available to be incorporated into agencies’ existing dashboards. We provide a plan for moving forward with this concept. (auth)
Improved parametrization of the growth index for dark energy and DGP models

description: We propose two improved parameterized form for the growth index of the linear matter perturbations: (I) $γ(z)=γ_0+(γ_{\infty}-γ_0){z\over z+1}$ and (II) $γ(z)=γ_0+γ_1 \frac{z}{z+1}+(γ_{\infty}-γ_1-γ_0)(\frac{z}{z+1})^α$. With these forms of $γ(z)$, we analyze the accuracy of the approximation the growth factor $f$ by $Ω^{γ(z)}_m$ for both the $ω$CDM model and the DGP model. For the first improved parameterized form, we find that the approximation accuracy is enhanced at the high redshifts for both kinds of models, but it is not at the low redshifts. For the second improved parameterized form, it is found that $Ω^{γ(z)}_m$ approximates the growth factor $f$ very well for all redshifts. For chosen $α$, the relative error is below 0.003% for the $Λ$CDM model and 0.028% for the DGP model when $Ω_{m}=0.27$. Thus, the second improved parameterized form of $γ(z)$ should be useful for the high precision constraint on the growth index of different models with the observational data. Moreover, we also show that $α$ depends on the equation of state $ω$ and the fractional energy density of matter $Ω_{m0}$, which may help us learn more information about dark energy and DGP models.

Las colocaciones lexicas en aprendientes españoles de italiano como LE y aprendientes italianos de español como LE
Creators: name: Minervini, Rosaria
Publisher: name: Annali - Sezione Romanza
Year: 2020

description: El objetivo de este estudio es presentar el uso que hacen de las colocaciones léxicas aprendientes italianos de español como LE y aprendientes españoles de italiano como LE en los niveles A1 y B1 del MCER. Para llevar a cabo el análisis, se ha recurrido al CORpus del ESPañol de los Italianos (CORESPI) y al CORpus del ITaliano de los Españoles (CORITE), y los datos sobre el uso de las colocaciones se han analizado desde una óptica cualitativa y cuantitativa. Una vez descrita la importancia de los estudios sobre la interlengua de lenguas afines para mejorar el proceso de enseñanza-aprendizaje y tras haber esbozado qué se entiende por colocación léxica, se analiza la interlengua de estos aprendientes estudiando el tipo de estrategias de aprendizaje que aplican a la hora de aprender estos elementos del sistema lingüístico. Además, se ha pretendido dilucidar si estos elementos aparecen ya en los primeros niveles del aprendizaje por tratarse de lenguas afines y si su aparición se da de manera similar en aprendientes de español y de italiano como lengua extranjera. Finalmente, los datos de los dos niveles se cotejan para averiguar las diferencias de uso entre ambos desde un punto de vista tanto cualitativo como cuantitativo

The effect of 5 mg of Diazepam on driving-related skills : equating impairment to a blood-alcohol concentration level, and investigating subjective perception of impairment
Creators: name: Derrick, ML
Publisher: name: University Of Tasmania
Year: 2023

description: A mixed-measures research design was employed to investigate the effects of a single acute 5mg dose of diazepam on psychomotor performance and subjective experience. Following a doubleblind protocol, 34 benzodiazepine-naive participants were administered 5mg of diazepam or placebo. Tasks measuring the driving-related skills of psychomotor processing speed, sensory motor reaction time, vigilance, divided attention and tracking, as well as subjective alertness and subjective competence, were completed for 150 minutes post-ingestion. Deleterious effects of diazepam tended to peak at 60 minutes post-ingestion, with the largest effects being of a moderate magnitude. Psychomotor processing speed and vigilance were more deleteriously affected than sensory motor reaction time and divided attention. Dissociations between the alertness and competence ratings given before and after test battery completion suggest that self-monitoring accuracy may not be fully intact under the influence of the 5mg dose. A method for equating impairment to a blood-alcohol concentration (BAC) equivalency was trialled. This method involved the application of a regression equation to performance decrement measurements from the tracking task. The BAC equivalency of impairment found in the current study utilising this method was .041%, however it is recognised that this is likely to be an underestimation for older diazepam users and for people taking regular, repeated 5mg doses for the first several weeks. Consequently, many diazepam users may be impaired by diazepam to an extent considered risky for driving (more than .05% BAC). It is reasonable to suggest that Medical Practitioners should educate patients when prescribing diazepam, so that patients are aware of the steps they can take to reduce their crash risk when under the influence of diazepam.

description: We develop a new integration technique allowing one to construct a rich manifold of particular solutions to multidimensional generalizations of classical $C$- and $S$-integrable Partial Differential Equations (PDEs). Generalizations of (1+1)-dimensional $C$-integrable and (2+1)-dimensional $S$-integrable $N$-wave equations are derived among examples. Examples of multidimensional second order PDEs are represented as well.

description: We study the quantum Hall effect (QHE) in graphene based on the current injection model. In our model, the presence of disorder, the edge-state picture, extended states and localized states, which are believed to be indispensable ingredients in describing the QHE, do not play an important role. Instead the boundary conditions during the injection into the graphene sheet, which are enforced by the presence of the Ohmic contacts, determine the current-voltage characteristics.

description: En matière de féminisation des noms de métiers, grades et fonctions, la question de savoir si un mot doit son existence et, d’une certaine façon, sa légitimité dans le patrimoine lexical d’une langue, à la norme qui l’impose ou à l’usage qui l’implante, est cruciale. Cette communication se veut tout d’abord un état des lieux sur l’actuelle féminisation des noms de métiers, tant du point de vue de la politique volontariste de l’État français (circulaires, recommandations), que du point de vue strictement linguistique (marques du genre, opposition de type morphologique, lexical, arbitraire et motivation...). En étendant notre enquête à l’espace francophone (politiques belges, québécoises...), on abordera les questions et points suivants : les recommandations sont-elles suivies ? ; les freins, les blocages ; les polémiques ; les différences entre dictionnaires. On s’interrogera sur le mode d’évaluation de ces implantations. Grâce aux nouveaux outils (archives web de la Bibliothèque Nationale de France), on proposera une mesure d’implantation à grande échelle à partir d’exemples précis (ex : cheffe entre 2016-2017)

description: We present a structural analysis of the graphene/Ru(0001) system obtained by surface x-ray diffraction. The data were fit using Fourier-series expanded displacement fields from an ideal bulk structure, plus the application of symmetry constraints. The shape of the observed superstructure rods proves a reconstruction of the substrate, induced by strong bonding of graphene to ruthenium. Both the graphene layer and the underlying substrate are corrugated, with peak-to-peak heights of (0.82 +/- 0.15) A and (0.19 +/- 0.02) A for the graphene and topmost Ru-atomic layer, respectively. The Ru-corrugation decays slowly over several monolayers into the bulk. The system also exhibits chirality, whereby in-plane rotations of up to 2.0 degrees in those regions of the superstructure where the graphene is weakly bound are driven by elastic energy minimization.

description: Fe-Pd-based ferromagnetic shape memory alloys constitute an exciting class of magnetically switchable smart materials that reveal excellent mechanical properties and biocompatibility. However, their application is severely hampered by a lack of understanding of the physics at the atomic scale. A many-body potential is presented that matched ab inito calculations and can account for the energetics of martensite ↔ austenite transition along the Bain path and relative phase stabilities in the ordered and disordered phases of Fe-Pd. Employed in massively parallel classical molecular dynamics simulations, the impact of order/disorder, point defects and severe plastic deformation in the presence of single- and polycrystalline microstructures are explored as a function of temperature. The model predictions are in agreement with experiments on phase changes induced by ion irradiation, cold rolling and hammering, which are also presented.

description: We study longwave Marangoni convection in a layer heated from below. Using the scaling $k = O(\sqrt{\rm Bi})$, where $k$ is the wavenumber and ${\rm Bi}$ is the Biot number, we derive a set of amplitude equations. Analysis of this set shows presence of monotonic and oscillatory modes of instability. Oscillatory mode has not been previously found for such direction of heating. Studies of weakly nonlinear dynamics demonstrate that stable steady and oscillatory patterns can be found near the stability threshold.

La manifesta oscurità del peccato. La donna dandy e il paradosso satanico in Barbey d’Aurevilly
Creators: name: Di Benedetto, Angela
Publisher: name: Annali - Sezione Romanza
Year: 2020

description: Onnipresente nell’opera romanzesca di Barbey d’Aurevilly, il satanismo assume nelle Diaboliques un carattere che potremmo definire paradossale. Paradossale per l’incontro, nelle figure femminili qui rappresentate, tra il furore erotico e pulsionale della femme fatale fin de siècle e l’elegante distacco del dandy. Paradossale anche per la contraddizione inscritta nel loro essere tra il bello, concepito come artificio, e l’animalità intesa come forza istintuale. Le donne diaboliche di queste novelle rappresentano infatti un paradosso nell’epoca moderna: da una parte si inscrivono nella discendenza baudelairiana per i tratti tipici del dandy che connotano le protagoniste (la freddezza, l’imperturbabilità e l’abilità di dissimulare intenti ed emozioni), dall’altro quei tratti li attribuiscono all’essere nel quale Baudelaire vedeva la vera antitesi del dandy, la donna, qui, essenza di sadica crudeltà

description: We study the primordial spectra and the gravitational-wave background (GWB) of three models of semi-classical, quantum or string gravity where the big bang is replaced by a bounce and the primordial tensor spectrum is blue: ekpyrotic universe with fast-rolling Galileons, string-gas cosmology with Atick-Witten conjecture and pre-big-bang cosmology. We find that the ekpyrotic scenario with Galileons does not produce a GWB amplitude detectable by present or third-generation interferometers, while the Atick-Witten-based string-gas model is ruled out in its present form for violating the big-bang-nucleosynthesis bound, contrary to the original string-gas scenario. In contrast, the GWB of the pre-big-bang scenario falls within the sensitivity window of both LISA and Einstein Telescope, where it takes the form of a single or a broken power law depending on the choice of parameters. The latter will be tightly constrained by both detectors.

Formation and catalytic properties of some ruthenium (II) olefin complexes in solution.
Creators: name: Louie, Judy Sok Beng
Publisher: name: University of British Columbia
Year: 2011

description: A kinetic study of the complex formation between chlororuthenate (II) species and the olefinic substrates, 1,1 difluoroethylene, fluoroethylene and acrylamide in aqueous hydrochloric acid solution has been carried out. The kinetics were studied either by measurement of gas uptake or by following spectrophotometrically at 680 mμ the disappearance of the blue Ru (II) species at experimental conditions in which ruthenium, olefin and chloride concentrations were varied. A two step process involving an initial dissociation of a chloride ligand seems likely for these systems, but a detailed discussion is limit ed by lack of information on the equilibria between chlororuthenate (II) species in solution. No evidence was obtained for hydrogenation by molecular hydrogen of the 1,1 difluoroethylene or fluoroethylene through a π-complex formed with the chlororuthenate (II) species. Catalytic hydration of these olefins to acetic acid and acetaldehyde respectively was however observed, and a mechanism is proposed to account for this; this appears to be the first, report of a transition metal catalysed hydration of olefins. Acrylamide was not hydrated but could be catalytically hydrogenated to propionamide; the kinetic data fit a well established mechanism. Similarities between the hydrogenation and hydration processes are pointed out.
