Superficial peels cause injury to the epidermis, so are used to treat superficial conditions, including melasma, acne, and dyschromias.
Skin conditions that can be treated by the GP according to the committee, are viral infections concerning the herpes simplex virus and the varicella zoster virus, venous ulcera cruris, venous insufficiency oedema, and superficial skin conditions concerning bacteria, fungi and yeast.
A rare CNS condition, superficial siderosis, is caused by repeated subarachnoid hemorrhage (Fearnley et al., 1995; Levy, et al., 2007; Yamawaki 2012) that results in the deposition of hemosiderin in the subpial layer of the brain and/or spinal cord, and/or in cranial nerves (Yamawaki 2012).
(i) fluidization conditions (superficial gas velocity, settled bed height), (ii) particle properties (minimum fluidization velocity), and (iii) bed size (diameter).
Agreement of results obtained with this model with existing literature data is good, especially at lower superficial gas velocity conditions.
The CFB risers were operated over a wide range of industrially relevant conditions: superficial gas velocities from 6.5 to 18.3 m/s with solid fluxes from 20 to 400 kg/m2/s.
An explicit formula for the creep velocity is derived in terms of the end conditions, superficial velocity, heat capacity ratio between phases, and heat of reaction.
Experiments were performed in a cylindrical bubble column under dilute to dense conditions (superficial gas velocity (UG) in the range of 1 40 cm/s).
This study also showed that there existed the flow plugging phenomena in the low region of the test section at high superficial gas velocity conditions in the vertical large diameter pipe.
