“Our Artillery Would Smash It All Up:” Canadian Artillery During the Battle of the Somme, September-November 1916

The historiography of the First World War has produced no recent comprehensive study of the Canadian artillery, despite its importance on the battlefield. This article seeks to explain how Canadian artillery evolved on the Somme. The central conclusions of this article are that the Canadian artillery’s performance during the battle was mixed, and that a number of technological, tactical, and organizational changes, not all of them Canadian, in the Canadian Corps that we recognize from the artillery of 1917-1918 were developed during, or as a result of, the Somme

Rahul Sankrityayan, Tsetan Phuntsog and Tibetan Textbooks for Ladakh in 1933

In 1933 the Indian scholar and social activist Rahul Sankrityayan (1893-1963) compiled a set of four Tibetan-language readers and a grammar for use in Ladakhi schools, together with his Ladakhi colleague Tsetan Phuntsog. The readers contain a mix of material from Western, Indian, Ladakhi and Tibetan sources. This includes simple essays about ‘air’ and ‘water’, selections from Aesop’s fables, Indian folk stories, biographies of famous people in Ladakhi and Tibetan history, poems by Ladakhi authors, and extracts from the Treasury of Elegant Sayings by Sakya Pandita Kunga Gyaltsen (1182-1251). This essay begins with a review of earlier Tibetan-language schoolbooks published in British India, and then discusses the circumstances that led to Sankrityayan’s involvement in the Ladakh project. The second part of the essay examines the contents of the readers and the grammar, including—where possible—the authorship of particular sections. Finally, the essay briefly reviews linguistic developments in Ladakh since the publication of the textbooks

Hydrodynamic capabilities of an SPH code incorporating an artificial conductivity term with a gravity-based signal velocity

This paper investigates the hydrodynamic performances of an SPH code incorporating an artificial heat conductivity term in which the adopted signal velocity is applicable when gravity is present. In accordance with previous findings it is shown that the performances of SPH to describe the development of Kelvin-Helmholtz instabilities depend strongly on the consistency of the initial condition set-up and on the leading error in the momentum equation due to incomplete kernel sampling. An error and stability analysis shows that the quartic B-spline kernel (M_5) possesses very good stability properties and we propose its use with a large neighbor number, between ~50 (2D) to ~ 100 (3D), to improve convergence in simulation results without being affected by the so-called clumping instability. SPH simulations of the blob test show that in the regime of strong supersonic flows an appropriate limiting condition, which depends on the Prandtl number, must be imposed on the artificial conductivity SPH coefficients in order to avoid an unphysical amount of heat diffusion. Results from hydrodynamic simulations that include self-gravity show profiles of hydrodynamic variables that are in much better agreement with those produced using mesh-based codes. In particular, the final levels of core entropies in cosmological simulations of galaxy clusters are consistent with those found using AMR codes. Finally, results of the Rayleigh-Taylor instability test demonstrate that in the regime of very subsonic flows the code has still several difficulties in the treatment of hydrodynamic instabilities. These problems being intrinsically due to the way in which in standard SPH gradients are calculated and not to the implementation of the artificial conductivity term.Comment: 26 pages, 15 figures, accepted for publication in A&

Owner challenges on major projects: The case of UK government

Many studies agree that owner organisations are important for successful project organising, but they tend to focus on particular aspects of project organising rather than providing a holistic analysis of owners as organisations. Our objective is to collect evidence of the full range of challenges public sector owners face in managing their major projects. After reviewing the literature on owner organisations, we carry out a case survey of 26 major projects to identify the principal challenges using a content analysis of UK National Audit Office Value for Money reports. Our original contribution is that the findings provide the first comprehensive picture of the full range of challenges of project organising faced by owner organisations. These findings push us theoretically to extend the scope of research in project organising to identify an extended core set of dynamic capabilities for project owner organisations to address these challenges

Distances to nearby molecular clouds and star forming regions.III. Localizing extinction jumps with a Hipparcos calibration of 2mass photometry

We want to estimate the distance to molecular clouds in the solar vicinity in a statistically precise way. Clouds are recognized as extinction discontinuities. The extinction is estimated from the $(H-K) \ vs. \ (J-H)$ diagram and distances from a $(J-K)_0 \ vs. \ M_J$ relation based on Hipparcos. The stellar sample of relevance for the cloud distance is confined by the FWHM of the $A_V / D_{\star}(pc)$ or of its derivative. The cloud distance is estimated from fitting a function to the $(A_V, 1/ \pi_{JHK})$ pairs in this sample with a function like $arctanh^p (D_\star /D_{cloud})$ where the power $p$ and $D_{cloud}$ both are estimated. The fit follows the $(A_V, 1/\pi_{JHK})_{cloud}$ data rather well. Formal standard deviations less than a few times 10 pc seem obtainable implying that cloud distances are estimated on the $\lesssim$10$\%$ level. Such a precision allows estimates of the depths of cloud complexes in some cases. As examples of our results we present distances for $\sim$25 molecular clouds in Table ~\ref{t2}. $Keywords$: interstellar medium: molecular cloud distance

Astrophysical Weighted Particle Magnetohydrodynamics

This paper presents applications of weighted meshless scheme for conservation laws to the Euler equations and the equations of ideal magnetohydrodynamics. The divergence constraint of the latter is maintained to the truncation error by a new meshless divergence cleaning procedure. The physics of the interaction between the particles is described by an one-dimensional Riemann problem in a moving frame. As a result, necessary diffusion which is required to treat dissipative processes is added automatically. As a result, our scheme has no free parameters that controls the physics of inter-particle interaction, with the exception of the number of the interacting neighbours which control the resolution and accuracy. The resulting equations have the form similar to SPH equations, and therefore existing SPH codes can be used to implement the weighed particle scheme. The scheme is validated in several hydrodynamic and MHD test cases. In particular, we demonstrate for the first time the ability of a meshless MHD scheme to model magneto-rotational instability in accretion disks.Comment: 27 pages, 24 figures, 1 column, submitted to MNRAS, hi-res version can be obtained at http://www.strw.leidenuniv.nl/~egaburov/wpmhd.pd
