Background Use of popliteal nerve blocks (PNBs) as an alternative or adjunctive therapy to traditional methods of pain control (e.g., systemic or spinal anesthesia and opioids) is increasingly popular in foot and ankle surgery. Methods We reviewed on

This research investigated a new technique known as foam granulation for the continuous manufacturing of pharmaceuticals by a twin screw extruder. Six grades of hypromellose were compared as binders in the trials, using two addition methods: foam inj

This paper investigates foam granulation in a twin screw extruder as a new continuous wet granulation technique for pharmaceutical powder drug formulations. Foamed aqueous binder has a reportedly lower soak-to-spread ratio than drop or spray liquid a

The influence of filler selection in wet granulation was studied for the novel case where the binder is delivered as an unstable, semi-rigid aqueous foam to an extrusion process. The work primarily examined the impact of differing concentrations of m

The effects of conventional, bole only harvesting (CH) and whole-tree harvesting (WTH) on major inorganic nutrient concentrations (K, NO3-N, NH4-N, PO4-P and Ca) in soil water are described from Beddgelert forest in North Wales. Monitoring of nutrien

Hydrochemical data have been collected for between 6 and 9 years from forest harvesting experiments in small catchments (>10 ha) at Plynlimon and Beddgelert, Wales, UK. Felling resulted in rapid increases in NO 3 - and K+ concentrations at both sites

The options for large scale liming of river systems are reviewed with particular reference to the River Tywi in Wales, a major salmonid river with a reservoir in the upper catchment. For hydrological source area liming the cost of lime transport is h

Catchment liming is one of the main techniques available for treating acidified surface waters. It also provides one of the few tests of models developed to forecast the effects of future changes in stream chemistry. In this study, three experimental

The survival of artificially implanted eggs, alevins and parr of brown trout Salmo trutta (L.) was assessed in streams of different acidity. Chemical analysis included detailed aluminium speciation of surface and interstitial water samples, taken ove

The distribution of larvae of the dragonfly Cordulegaster boltoni was assessed in eighteen streams in contrasting land use in the upper catchment of the River Tywi, mid-Wales, in each year during 1985–1989, inclusive. Larvae occurred abundantly in
