Background: Complete tumour response (pCR) to neo-adjuvant chemo-radiotherapy for rectal cancer is associated with a reduction in local recurrence and improved disease-free and overall survival, but is achieved in only 20–30% of patients. Drug repu

An experimental field trial was performed on Ilkley Moor, an upland moor in northern England, to assess the effectiveness of two cutting treatments as alternatives to traditional moorland burning practice. Plots where the above-ground vegetation was

The effects of frequency of application, initial soil moisture content, rate of water application and soil organic matter content on the accumulation of dimethoate in different soils have been studied in the laboratory. It was found that: residual ac

Soils collected from the Gezira irrigation scheme in Sudan were incubated with five pesticides (pyrolan, α‐and β‐endosulphan, γ‐HCH and dieldrin), using three independent methods (incubation of microbial culture with soil and leachates, with

The effects of pH, ultra‐violet irradiation and temperature on the persistence and breakdown of dieldrin, endosulphan, gamma‐HCH and pyrolan were studied in leachates from a loam soil. Except for dieldrin which remained exceptionally stable throu

It was found that pH, temperature and the type of medium are important factors affecting the stability of dimethoate in soils and solutions. Evaporation is a minor factor in determining the loss of dimethoate from water. Within the pH range of 7–11

For a given application of dimethoate, the loss by leaching increased with soil type in the following order: clay clay loam > sand > S.C.L. > loam. However, the loss due to evaporation alone was in the order; sand > S.C.L. > clay loam > loam. Biologi

The effect of concentration on leachability and adsorption of γ‐HCH, dieldrin, endosulphan and pyrolan was studied in a sandy clay loam from Northern England (Yorkshire region), under laboratory and greenhouse conditions. Concentration did not aff
