چکیده
We develop a theoretical model for a fluidic current source consisting of a via, a detour channel, and a push-up type micro-valve. The model accurately describes the non-linear behaviour of this type of device, which has been previously measured experimentally. We show how various structural parameters and material properties of the device influence the saturated flow rate and the minimum driving pressure required for the device to function as a current source. Conversely, the model can be used to design a fluidic current source with a desired saturated flow rate and low operational pressure. The present model can be straightforwardly applied to microfluidic circuits composed of many functional autoregulatory devices.

He took his M.D. in 1890. He was appointed House Surgeon to the Children's Hospital, then Registrar and in 1896 Physician : he held this appointment until 1905 when he was appointed Consultant Physician. During the whole of his life, until he retired in 1946, he was in busy general practice, and endeared himself to all whom he met, patients and colleagues alike. He was an enthusiastic pioneer m...

متن کامل‘Chronophilia’: Entries of Erotic Age Preference into Descriptive Psychopathology
A scientific nomenclature of erotic age preferences informed the mid- through late nineteenth century joint appearance of homosexuality and sexual abuse of minors on the medico-legal scene. Yet, even in the twenty-first century, legal, psychiatric and culture-critical dimensions of related terms are rarely cleanly distinguished. Review of primary sources shows the ongoing Western suspension of ...
