THE MODE OF ACTION OF SULFANILAMIDE ON STREPTOCOCCUS. II [PDF]

open access: yesJournal of Experimental Medicine, 1939
The precise mode of therapeutic action of sulfanilamide on streptococcus can be arrived at only by considering the sum total of factors that inhibit or favor the natural growth of the microorganism under the experimental conditions that obtain, whether in vivo or in vitro.

Effect of loading mode and impact velocity on crack propagation of coal

open access: yesMeikuang Anquan, 2021
In order to study the influence of loading mode and impact velocity on coal crack propagation law, asymmetric semi-circular bend specimens were used to develop test and numerical simulation with multiple impact speeds under three loading modes of mode Ⅰ,

Delivering interlaminar reinforcement in composites through electrospun nanofibres

open access: yesAdvanced Manufacturing: Polymer & Composites Science, 2019
Electrospun nonwoven veils comprising thermoplastic fibres (average diameter 400–600 nm) based on polysulfone (PSU), polyamide (PA-6,6), and polyetherimide (PEI) have been fabricated and used as interlaminar reinforcements in carbon fibre composites ...

II. A new mode of respiration in the myriapoda [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. (B.), 1892
Abstract In the course of some work which I have been doing lately, 1 have been led to consider the systematic position of the Scutigeridæ or Cermatidæ. C. L. Koch, in his well known work, “System der Myriapoden,” includes this group in an order by itself, dividing the Myriapods into three orders of ecpial value.

Semilattice modes II: the amalgamation property [PDF]

open access: yesAlgebra Universalis, 1995
Although varieties of semilattice modes behave in many ways like those of modules, there is at least one important difference: varieties of semilattice modes do not necessarily have the amalgamation property. However, if the semiring \(R({\mathcal V})\) shown to be associated with each variety \({\mathcal V}\) of semilattice modes in the first of these

Experimental Study on Delamination of Composite Laminates with 0°/45° Interface under Mode I, Mode II and Mixed-mode I/II Loading

open access: yesJournal of Aeronautical Materials, 2018
High performance carbon-reinforced composite materials have become important aeronautical materials. During the service time, the delamination fracture of composite structures is a common failure mode.
