The ionization theory of discharge in gases may in many respects be considered a model of the mathematical treatment of physical processes. Townsend and subsequently Schumann succeeded in describing, not only qualitatively but also quantitatively, the entire diversity of discharge phenomena both in …

Book Review: S.N. Rzhevkin. Hearing and Speech in the Light of Modern Physical Research.
This article was first published in the “Bell System Technical Journal” and subsequently appeared in a German translation as a separate booklet with a preface by E. Schrödinger (published by S. Ilirzel, Leipzig, 1929). The present translation was made from the original English text and checked again…

Presidential Address delivered at the opening of the Section of Mathematical and Physical Sciences of the British Association for the Advancement of Science, July 24, 1929.
This article examines the production of solid carbon dioxide and its possible use as a refrigerant for long-distance transport of perishable goods, especially Siberian export butter. It surveys the practical advantages of dry ice, develops thermodynamic and cost calculations for a multistage carbon …
This paper examines the Dörfel springless cam valve steam distribution system for steam engines, emphasizing its design features, operating characteristics, and comparison with other forced cam valve systems such as Lentz, Proell, and Stumpf. Using a numerical design example for the high-pressure cy…
The paper addresses the selection of economically advantageous diameters for branched compressed gas or steam pipelines, a problem not resolved by prescribing velocity or allowable pressure loss alone. It formulates the annual cost as the sum of compression energy, pipeline amortization and repair, …
This paper presents a proposed logarithmic sheet, Type A, intended as a cheaper and more accurate substitute for the ordinary slide rule. Shubin describes the layout of primary, secondary, and intermediate logarithmic scales, together with printed rulers, and explains how products, quotients, powers…
This paper presents a modified use of the method of foci for analyzing statically indeterminate frame structures, with particular attention to constructing influence lines. The proposed approach interprets influence lines through the elastic rotation and displacement of frame joints, allowing suppor…
This paper examines methodological ambiguities in the 1927 All-Union Standard for testing the constancy of volume of Portland cement, especially the reliance on visually noticeable warping and radial cracks in cement pats. It argues that the standard should specify procedures for detecting fine defo…
This paper examines whether distillery stillage should be dried at Siberian distilleries, with special attention to the Novosibirsk plant, where seasonal disposal problems arise. It reviews proposed drying systems, argues that export of dried stillage from Siberia is economically doubtful, and repor…
This paper examines the deterioration of Siberian export butter during long summer transport to foreign markets and argues that existing ice-cooled railway refrigeration was insufficient in both capacity and temperature depth. Using shipment statistics, grading data, price comparisons, and estimates…
This paper examines the gravimetric determination of lead as lead sulfate in solutions containing ferric iron, a condition insufficiently specified in standard analytical procedures. Through controlled precipitation experiments with lead nitrate, ferric nitrate, sulfuric acid, varied standing times,…
This study examines how selected Kuznetsk Basin coals change during oxidation in storage and under accelerated laboratory conditions, with particular attention to caking ability, calorific value, volatile products, and coking behavior. The authors compared summer open-air storage of several Kemerovo…
This paper develops analytical and graphical-analytical procedures for determining the attitude elements of a bed surface at a given point, especially the azimuth and zenith distance of the line of dip and the related strike direction. It argues that practical exploration cases, including observatio…
This note addresses inconsistencies in the derivation and use of formulas for the vertical angle and the horizon reading in geodetic and mine-surveying instruments. It proposes a theoretical treatment based on the distinction between senior and junior directions of readings and on the use of a desig…
This article surveys landslide hazards affecting cities and railway approaches along the Middle and Lower Volga, emphasizing their hydrogeological causes, aggravation by river erosion, and intensification through construction, damaged drainage, water-supply leakage, and wartime neglect. Drawing on r…
This paper examines landslide damage affecting railway earthworks in the North Caucasus and along the Black Sea coast, with particular attention to drainage-based stabilization methods. Drawing on field observations, railway administration records, engineering designs, and geological interpretations…
This paper investigates the appearance and growth of numerous cracks in a 123.75 meter railway bridge truss, first observed in small numbers and later recorded as 52 defects distributed across chords, posts, and bracing members. It combines detailed visual inspection, leveling and geometric measurem…
This article surveys the sanitary and economic problem of removing and using sludge produced by mechanical wastewater treatment, with particular attention to sludge from settling structures. Drawing on contemporary European and American data, it compares sludge quantities, moisture content, composit…
This paper examines nailed joints as simple, inexpensive connectors for timber structures, comparing them with bolts and steel dowel pins and surveying their use in beams, arches, trusses, and built-up compression members. It reports laboratory tests on pine board specimens joined with wire nails, i…
This study examines how pyridine is oxidized by potassium permanganate under neutral, alkaline, and acidic conditions, with attention to how reaction conditions affect product formation and possible reaction mechanisms. The authors oxidized pyridine at room temperature and at 70 to 80 degrees using …
This paper examines the preparation of simple ethers, especially phenyl ethers, by the Williamson reaction of sodium or potassium alcoholates with halogenated hydrocarbons. The authors review known limitations of the method, then describe preparative procedures using phenolates in alcoholic solution…
This paper examines the preparative use of acetic anhydride for converting alcohols into acetic acid esters, as an alternative to more cumbersome or costly methods reported for many of these compounds. The authors treated a series of primary, secondary, tertiary, unsaturated, cyclic, and aromatic al…
