though intravenous (iv) magnesium sulphate (mgs04) has additive effect to beta-2 agonists, its additive benefit in face of combination therapy with beta-2-agonists and ipratropium (standard therapy of severe acute exacerbation of asthma) remains unaddressed. the aim of this investigation was to evaluate the role of iv mgso4 when used as an adjunct to standard therapy of severe exacerbations of ...

As an emerging flexible-scale energy storage technology, underwater compressed gas (UW-CGES) is regarded as a promising option for offshore platforms, renewable farms, islands, coastal cities, etc. Liquid accumulation often occurs in transmission pipelines, which challenge to overcome. In this study, experimental investigation carried out on the pressure distribution characteristics of liquid f...

Hydrotalcites are a promising candidate for capturing CO2, but their strong inter-particle forces produce significant agglomeration and poor fluidisation quality in micro-fluidised bed technology. Therefore, this study we performed detailed hydrodynamic experiments using the pressure drop characterisation approach to identify viable MFBR designs operating conditions these Geldart C powders. Our...

main goal in the management of patients with severe traumatic brain injury (tbi) is control of intracranial pressure (icp). decompressive craniectomy is an accepted technique for control of refractory intracranial hypertension in patients with severe tbi. because of high complication rate after decompressive craniectomy, new techniques such as basal cisternostomy have developed. we herein repor...

About two-thirds of fields that exist in the world right now are classified as mature fields. Mature usually have a lot problems occurred during production. field is which has produced much fifty percent their established proved plus probable resources estimation or for more than twenty-five years. Empowerment well can be increasing efficiency productivity. Productivity decline caused by low ma...

Proportional-Integral-Derivative (PID) controllers reign absolute when automatic control is applied. There an expressive number of tuning rules for these in literature. However, highly oscillatory (or underdamped) systems, such as the ones found oil production and polymerization reactors, available methods provide poor closed-loop performance robustness. Besides, most are developed systems base...

Abstract Hydrothermal carbonization (HTC) reacts with biomass in water at a high temperature and pressure to produce hydrochar higher heating value (HHV) lower ash content than dry torrefaction. The potassium can promote thermochemical conversion; however, it lowers the melting of ash, causing slugging fouling. Therefore, this study, investigated effect on HTC sorghum bagasse by comparing remov...

Significant advances have taken place in the last few years in the development of control designs for nonlinear infinite-dimensional systems. Such systems typically take the form of nonlinear ODEs (ordinary differential equations) with delays and nonlinear PDEs (partial differential equations). In this article we review several representative but general results on nonlinear control in the infi...
