The particle size analysis of soils and its use in forensic science--the determination of particle size distributions within the silt and sand fractions.
Methods are described for the determination of the particle size distributions in small soil samples using a Coulter Counter Model ZB for the silt fraction (60μm–2μm) and conventional sieving for the sand fraction (2mm–60μm). An examination of the reproducibility of the methods using duplicate 1·5g samples of eighteen different soils has shown that they are highly reproducible and that the differences between the soils were easily demonstrated both in the silt and sand particle distributions. The methods have also been shown to be reproducible for sample weights as low as 200mg of whole soil.
USE OF THE COULTER COUNTER (MODEL B) FOR PARTICLE-SIZE ANALYSIS OF SOILS
THIS REPORT DEALS WITH THE CALIBRATION OF A MODEL B COULTER COUNTER AND METHODS DEVELOPED FOR ITS USE IN THE PARTICLE-SIZE ANALYSIS OF SOILS. COULTER COUNTER ANALYSES OVER A RANGE OF SOIL MATERIALS ARE COMPARED WITH DATA OBTAINED WITH A PLUMMET BALANCE, SEDIMENTATION BALANCE PIPETTE ANALYSIS, AND A SET OF STANDARD SQUARE-HOLED SIEVES. THE APPLICATION OF THE APPARATUS IN SEDIMENTOLOGICAL STUDIES IS DISCUSSED. /TRRL/
Code switching in Ahdaf Soueif's The Map of Love
This article examines the phenomenon of code switching in The Map of Love (1999) by the Egyptian—British writer Ahdaf Soueif. Though she chooses English as a medium for her creative expression, Soueif deploys Arabic in her narrative to represent different aspects of the linguistic and cultural norms of Egyptian society. The article's methodology is informed by Kachru's framework on contact literature and his categorization of the occurrence of literary code switching or bilingual creativity into different strategies that encompass cultural and linguistic processes. The results indicate the predominance in The Map of Love of the discourse strategies of employing lexical borrowing, culture-bound references and translational transfer. Finally, the article analyzes the functional motivation of code switching in the postcolonial context of the novel and how the use of certain creative strategies might enhance or diminish the narrative's effectiveness and readability.
