Among the hormones involved in milk production and release are oxytocin, prolactin, and dopamine. Oxytocin, released in pulsatile "spikes" from the posterior pituitary in response
Refractory the refractory castable is that is selected for an application, the physical properties of the material can be drastically reduced if care is not taken during the mixing, pouring, and curing processes. Particularly with the use of more complex refractory castables to solve specific wear issues, installation variables become even more critical to the performance of a lining. Unfortunately, lining quality is often compromised by field conditions during material placement. Project schedules, crew skill levels, equipment availability, job cost pressures, or other demands can sometimes influence proper refractory installation. Improper water addition, mix time variations, over- or under-vibration, and improper
