Ultrasonic washing of textiles.

We present the results of experimental investigation of ultrasonic washing of textiles. The results demonstrate that cavitation bubbles oscillating in acoustic fields are capable of removing soils from textiles. Since the washing performance is mitigated in a large washing bath when using an ultrasonic transducer, we propose a novel washing scheme by combining the ultrasonic vibration with a co...

Hand washing for preventing diarrhoea.

BACKGROUND Diarrhoea is a common cause of morbidity and a leading cause of death among children aged less than five years, particularly in low- and middle-income countries. It is transmitted by ingesting contaminated food or drink, by direct person-to-person contact, or from contaminated hands. Hand washing is one of a range of hygiene promotion interventions that can interrupt the transmission...

Autophagy plays a WASHing game.

Beclin 1 is a crucial regulator of autophagy. It forms a complex with ATG14L, VPS34 or the class III phosphatidylinositol 3-kinase AMBRA1 to control autophagosome formation. A study in this issue of The EMBO Journal (Xia et al, 2013) reports that WASH, a protein known to regulate endosomal sorting, hampers autophagy by inhibiting the AMBRA1-dependent polyubiquitylation of Beclin 1. This modific...

A machine for washing Wassermann tubes.

One of the most irksome tasks in a pathological department is the washing of test-tubes. Particularly is this so when a thousand or more tubes have to be washed at the end of a long day doing Wassermann and Kahn tests. If the task is postponed to the next day the cleaning process becomes more difficult. It seemed that a machine was needed for the mechanical rinsing of tubes immediately after th...
