Rotavirus removal in waste stabilization ponds is a relatively slow process: in a series of ten ponds (a 1-d anaerobic pond followed by nine 2-d ponds) its numbers were reduced from 1.4 × 105 per litre to zero, and in an “innovative” series (a 1-day anaerobic pond, 3-d facultative pond, 3.8-d, 3-d and 5-d maturation ponds) from 5.1 × 104 per litre to <5 per litre. Faecal coliforms were better indicators of rotaviruses than was Clostridium perfringens .

Vacuum furnace has been used for brazing repair of aerospace components, but it is a slow process which typically takes a few hours. The prolonged heating and cooling cycles could cause some adverse effects on the components such as excessive grain growth. A rapid brazing technique using induction coil was studied to evaluate its suitability for localized repair. Induction brazing of Inconel 718 was carried out using AMS 4777 brazing paste at different temperatures (950 °C, 1050 °C and 1150 °C ) for various durations (2 min, 10 min and 20 min). Microstructure and microhardness were evaluated. The experimental results show that brazing at 1050 °C leads to desirable microstructures in a short period of merely 2 min. The study demonstrates the potential application of induction brazing for rapid localized aerospace repair.

Subcortical structures are in a strategic functional position within the cognitive networks and their lesion can interfere with a great number of functions. In this study, we describe fourteen subjects with exclusively subcortical vascular lesions (eight in the basal ganglia and six in the thalamus) and the interrelation between their language alterations and other cognitive abilities, as attention, memory and frontal executive functions. All patients were evaluated through the following batteries: Boston Diagnostic Aphasia Examination, Boston Naming Test, Token Test, Benton Visual Retention Test, Trail Making, Wisconsin Card Sorting Test and a frontal scripts task. All patients underwent MRI and twelve underwent SPECT. Results show that these patients present impairment in several cognitive domains, especially attention and executive functions. These alterations affect language abilities, and this fact must be considered in the rehabilitation efforts.
