The purpose of this study was to determine the effectiveness of pneumatic reduction of intussusception using equipment readily available in the hospital. Twenty-two children aged between four months and four years had pneumatic reduction of intussusception. The device used was assembled using (i) a hand-held pump attached to a pressure gauge, and (ii) a 3-way Foley's balloon catheter. There was...

the colorado beetle, leptinotarsa decemlineata (say), is the major defoliating and exotic insect pest of potato plants and has caused serious problems in the east azerbaijan and ardabil regions of iran since emerging in the absence of natural native enemies. in the development of a suitable control strategy based on integrated pest management, it is important to recognize control methods that d...

The utilization of pneumatic muscles in the actuation of robotized systems is still in its early stages, hence the requirement of a study of such constructive solutions. Consequently the paper presents the constructive solution and performance of a robotized arm actuated by pneumatic muscles. This system is mounted on a wheelchair for persons with locomotive disabilities. The main reason underl...

UNLABELLED To evaluate whether, by using an arthropump (irrigation equipment with pressure sensor), pneumatic tourniquet use could interfere with the duration of surgery, recovery of movement and joint volume in patients who underwent knee videoarthroscopy for partial meniscectomy. METHODS 103 patients divided randomly into two groups regarding use or nonuse of a pneumatic tourniquet were eva...

Engineering estimates of methane emissions from natural gas production have led to varied projections of national emissions. This work reports direct measurements of methane emissions at 190 onshore natural gas sites in the United States (150 production sites, 27 well completion flowbacks, 9 well unloadings, and 4 workovers). For well completion flowbacks, which clear fractured wells of liquid ...
