In this paper, Steam Assisted Gravity Drainage (SAGD) is introduced and its advantages over ordinary steam injection is demonstrated. A simple simulation model is built and three scenarios of natural production, ordinary steam injection, and SAGD are compared in terms of their cumulative oil production and cumulative oil steam ratio. The results show that SAGD can significantly enhance oil prod...

OBJECTIVES this study examined the effect of immune modulation therapy (IMT) on claudication distances. MATERIALS AND METHODS a double-blind placebo controlled trial was performed on patients with disabling intermittent claudication with randomisation stratified for short and long distance IC. For IMT, following exposure to UV light, oxidisation and 42.5 degrees C, 10 ml of citrated autologou...

The spray formation and breakup of n-dodecane was investigated experimentally on a common rail diesel injector using a long working distance microscope. The objectives were to further the fundamental understanding of the processes involved in the initial stage of diesel spray formation under engine-like operating conditions, i.e. high ambient pressure and temperature. Present measurements show ...

BACKGROUND Despite widespread use of steroids to treat sacroiliac joint (SIJ) pain, their duration of pain reduction is short. Platelet-rich plasma (PRP) can potentially enhance tissue healing and may have a longer-lasting effect on pain. OBJECTIVES To assess the efficacy and safety of PRP compared with methylprednisolone in ultrasound-guided SIJ injection for low back pain. STUDY DESIGN Pr...

Background: Spasticity is one of the problems after a stroke. Due to this increase in muscle tone, patients are confronted with problems in motor control and difficulties in activities of daily living and complications such as shortness and contracture. The aim of this study was to examine the effects of the simultaneous use of both splint and botulinum toxin-A (BTX-A) injection on spasticity, ...

We have performed a prospective double-blind, randomised controlled trial over two years to evaluate the efficacy and safety of an intra-operative peri-articular injection of triamcinolone acetonide in patients undergoing medial unicondylar knee replacement. We randomised 90 patients into two equal groups. The study group received an injection of triamcinolone acetonide, bupivacaine, and epinep...
