Investigation of the final stages of a P4-like coliphage infection in Escherichia coli through scanning, transmission and nano-scanning-auger electron microscopy (NanoSAM)

Enlargement of bacterial cells during bacteriophage replication has been observed in the past with T-even, Lambda and N4 bacteriophages by the use of transmission electron microscopy (TEM) and light microscopy techniques and hypotheses explaining the enlargement of bacteriophage-infected cells have been postulated in literature. In this study, enlarged Escherichia coli cells were observed using scanning...

Assessment of soil erosion in the Ihsaniye watershed area, Afyonkarahisar, Turkey

  This article discusses research in which the authors apply the Universal Soil Loss Equation (USLE), Geographical Information Systems (GIS) and Remote Sensing (RS) to the mapping of the soil erosion risk in the Ihsaniye watershed, Afyonkarahisar, Turkey. The rainfall-runoff erosivity (R) factor was developed from annual precipitation data and from previous studies. Soil maps and soil survey data were used to...

A preliminary study on characterisation of mechanical behaviour of hydrated cement treated crushed rock base using the disturbed state concept

For road pavements in Western Australia, base layers are usually constructed using hydrated cement treated crushed rock base (HCTCRB) of which the mechanistic properties with the reliable material model are necessary for rational pavement analysis and design. The purpose of this study is to present the experimental results produced from the assessment of the mechanical behaviour of HCTCRB and the material modelling...

Interaction between suspended and settled solid particles in cassava wastewater

  Cassava (Manihot Esculenta, Crantz) is a very important staple food in most developing countries. During its processing into cassava flour or garri, wastewaters are generated and are indiscriminately discharged into the public sewers or into the environment and in some cases; the fermented wastewater is usually poured into latrines with the aim of degrading sewage. This study is aimed at finding out...
