Aqueous biphasic systems (ABS) or aqueous two-phase systems (ATPS) are clean alternatives for traditional organic-water solvent extraction systems.. ABS are formed when either two polymers, one polymer and one kosmotropic salt, or two salts (one chaotropic salt and the other a kosmotropic salt) are mixed at appropriate concentrations or at a particular temperature.

It happens if conjugated bilirubin is present. In an indirect positive test, the patient's serum is first treated with alcohol and later mixed with diazo reagent. This causes development of a red colour. It is seen if unconjugated bilirubin is present. If both conjugated and unconjugated bilirubin are present the reaction is termed a biphasic ...
The current mainstay of treatment is therapy-based. Specialist breathing techniques, most commonly termed biphasic breathing techniques or EILOBI are recommended to reduce turbulent inspiratory airflow and thus reduce chance of laryngeal closure. [18] Direct laryngeal visualisation during exercise to deliver biofeedback has been employed with ...
