Introduction: Restoring and maintaining normoglycemia by intensified insulin therapy in critically ill patients is a matter of ongoing debate since the risk of hypoglycemia may outweigh positive effects on morbidity and mortality. In this context, adsorption of insulin to different catheter materials may contribute to instability of glucose control. We studied the adsorption of insulin to diffe...

The wellbore downhole strings corrosion has attracted extensive interest as most of the oilfields in China enter high water-cut period. Injection inhibitors, one effective protection methods, is employed to mitigate corrosion. Nevertheless, its wider application suffers from insufficient knowledge regarding distribution inhibitors inside tubing, particularly with different inhibitor injection c...

Two new disposable cannulas for internal drainage of subretinal fluid are described in this article. We describe a curved and a straight version consisting of plastic hubs, 20 gauge proximal and 25 gauge distal stainless steel hypodermic tubing, and soft and flexible silicone tubing overmounts. Both these cannulas facilitate atraumatic drainage of subretinal fluid through pre-existing retinal h...

This study examined bacterial growth and type on biofilm-controlling dental unit waterline (DUWL) tubing (T) and control manufacturer's tubing (C) in a laboratory DUWL model using ultrapure source water that was cycled through the lines. Sections of tubing lines were detached and examined for biofilm growth using SEM imaging at six sampling periods. Bacteria from inside surfaces of T and C, sou...

In patients with traumatic injury of an upper limb it is often necessary to both secure intravenous (IV) access and record blood pressure noninvasively in the other upper limb. This may cause intermittent obstruction to the flow of IV fluids during cuff inflation. Also backflow of blood into the IV tubing when the cuff is inflated and the temporary stasis which occurs predisposes to clotting of...

A new optical pressure transducer system (Viggo) has been assessed and compared with a standard P10 transducer (Spectramed) using a similar 20-gauge cannula, both in vitro in terms of linearity and frequency response and in vivo using an animal model. The linearity of the transducers was comparable; the resonant frequencies were 106 Hz and 75 Hz, respectively. However, the resonant frequency of...

Background and Introduction In 2003 ETD held a successful International Conference and Workshop on HRSG Technology at which the importance of repair and maintenance technologies was recognised as a major factor in the successful and economic plant operation. As a relatively new, and rapidly evolving, technology HRSGs have had a history of faults, particularly in early models, which were not des...

Legionella spp. and Mycobacterium avium complex (MAC) are opportunistic pathogens of public health concern. Hot water systems, including showers, have been identified as a potential source of infection. This paper describes the colonization of Legionella and MAC on the flexible tubing within a model potable shower system, utilizing thermostatic mixing and a flexible shower head. A MAC qPCR meth...
