Method of Testing Oxygen Regulators

Oxygen regulators are used in aircraft to regulate automatically the flow of oxygen to the pilot from a cylinder at pressures ranging up to 150 atmospheres. The instruments are adjusted to open at an altitude of about 15,000 ft. and thereafter to deliver oxygen at a rate which increases with the altitude. The instruments are tested to determine the rate of flow of oxygen delivered at various altitudes and to detect any mechanical defects which may exist. A method of testing oxygen regulators was desired in which the rate of flow could be determined more accurately than by the test method previously used (reference 1) and by which instruments defective mechanically could be detected. The new method of test fulfills these requirements

The Graces of 2020: Catholic Campus Ministry Students Seek Out Blessings Amid a Tumultuous Year

Two staff members at DePaul University’s Catholic Campus Ministry (CCM), Amanda Thompson and Dan Paul Borlik, CM, offer their thoughts and those of CCM student leaders on the COVID-19 pandemic and other societal issues facing the US in 2020. The article relates how these issues affected the DePaul community. It also discusses how the students were formed in the practice of critical theological reflection and how they applied it as they experienced and responded to the crises of this terrible year. The authors note the particular relevance of the Exodus story in coping with 2020’s crises

Angling for the "Powte": a Jacobean Environmental Protest Poem

In his monumental 1662 history of the drainage of the fens, the antiquarian William Dugdale reports that outraged locals composed “libellous songs” to protest the theft of their commons. Preserving a rare specimen of this genre, Dugdale printed an anonymous ballad entitled “The Powtes Complaint.” The song adopts a non-human point of view to bewail the destruction of both the wetlands ecology and the fen-dwellers’ economy. This essay examines four different manuscripts of the ballad in the British Library, documenting their variants and commenting on their significance. It also seeks for answers to some pressing questions: when was the song written and where? What did it sound like? What socio-historical and environmental circumstances prompted its composition? How does the ballad portray the fenland ecology, and how does it compare with other seventeenth-century literary representations of the fens? What exactly is a pout? What is the nature of its complaint? And who was the person behind the song
