The present invention belongs to the field of pharmaceutical industry and relates to novel crystalline omeprazole sodium ethanol solvate and to the process for its preparation, which acts as intermediary compound to the processes for its conversion into different crystalline forms, first of all to a known omeprazole sodium form A, with low amount of residual solvents, i. WLAN devices communicate using WLAN protocols and PAN devices communicate using PAN protocols, allowing for lower power transmissions over the wireless medium relative to transmissions over the WLAN. 5 KHz to about 50 KHz may be applied to the patient’s spinal chord region to address low back pain without creating unwanted sensory andor motor side affects. A wiring connected to the protective elements and positioned under the grounding wiring and the power supply wiring is pulled out in a pulling-out region between the nMISFET forming region and the pMISFET forming region and between the grounding wiring and the power supply wiring to be connected to the conductive layer. During the steps of forming the HSG-Si layer, the temperatures of the first and second heaters are regulated to maintain the surface temperature of the wafer constant. The magnetic fastener is operable to be removably attached to the magnetic portion.
