INFLUENCE OF HYDROGEN-ION CONCENTRATION EXPONENT ON UNDRAINED SHEAR BEHAVIOUR OF BENTONITES

Theoretical Undrained Shear Behaviour of Unsaturated Soils

Prediction method for undrained shear behaviour of unsaturated soils is discussed in this paper. Based on Original Cam Clay model, authors have proposed constitutive model for unsaturated soils that the effect of water content is incorporated into superloading surface concept. Firstly, stress path of constant volume shear test is formulated under constant void ratio condition. And relationship ...

the influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry

بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...

Amphoteric Colloids. I. Cii_emical Influence of the Hydrogen Ion Concentration

I t is often stated (Pauli, H6ber, and others) that both ions of a neutral salt affect the physical properties of an amphoteric electrolyte (ampholyte) simultaneously and in the opposite sense; so that the total result is the algebraic sum of the opposite action of the oppositely charged ions of the neutral salt. 1 The writer has beelz able to show by experiments on gelatin and on pig's bladder...
