Performance Of A Novel In-Situ HCl For Carbonate and Sandstone Reservoirs
… reservoirs. Among these, hydrochloric acid (HCl) is the most commonly used acid because it is cheap and efficient. In carbonate reservoirs, HCl is used by itself to decrease skin damage by creating conductive wormholes; whereas in sandstone reservoirs, HCl is mixed generally with hydrofluoric …

An inquiry into the emergence of health care law in England and Wales as a distinct body of law : what lessons can be drawn from this in relation to Ghana?
… that a discrete body of health care law (HCL) can potentially offer more benefits to patients by providing protection for their rights and improving healthcare delivery as a result of making healthcare professionals and workers more aware of their legal duties towards patients than is the …

On the Development of Inductive Learning Algorithms: Generating Flexible and Adaptable Concept Representations
HCL achieves two functionalities: (1) flexibility in the representation, by increasing the complexity of the hypothesis comprised at each hierarchical layer, and (2) adaptability in the search for different representations, to know when to stop adding more layers in top of the hierarchical …

Release adjustment of drug combinations with different drug solubility
… to type of polymers, release of propranolol HCl was much faster than carbamazepine due to solubility differences. The modified method of simple mixing of EC with HPMC, followed by direct compression method, resulted in slower release of propranolol HCl. This retardation was attributed to …

Studies of trap generation in silicon-dioxide and electromigration in aluminum thin films
The effects of HCl on trap generation in SiO$\sb2$ film and at Si/SiO$\sb2$ interface at high electric fields are studied by avalanche electron injection. A comparison between a 9%-HCl-oxide MOS capacitor and a dry-oxide MOS capacitor shows that HCl decreases the hydrogenation rate of the boron …
