Low-pressure detachment nanolithography

Nanotechnology, 2006
A simple, one-step method is developed to fabricate various nanostructures such as nanoholes and nanolines based on the detachment of an organic polymer film in contact with a patterned polyurethane acrylate mould under a low physical pressure (1-2 bar) at ambient conditions.

Pressure control in a low-pressure casting furnace [PDF]

, 2005
The casting of light alloy components is a technology commonly used in aeronautic industry. This operation is possible, for example, using a low-pressure casting system, where it is important to control the temperature but also the maximum value and the time history of the pressure inside the furnace.

Reignition of an Arc at Low Pressures

Transactions of the American Institute of Electrical Engineers, 1934
An investigation of factors influencing the reignition potential of an alternating current arc at low pressure is reported in this paper. The investigation was undertaken to determine if such data could throw more light on the transition from a glow discharge to an arc. The results are consistent with a theory proposed previously by one of the authors.

Desalination at low temperatures and low pressures

Desalination, 2009
Abstract A low-temperature phase-change desalination process configuration is presented in this study. This configuration enables saline water to be evaporated at near-ambient temperatures under near-vacuum level pressures created by the barometric head without any mechanical energy input. Thermodynamic advantages and benefits of lowtemperature phase-

The Development of a New Piezoresistive Pressure Sensor for Low Pressures

IEEE Transactions on Industrial Electronics, 2018
This paper presents the design methodology and fabrication process of a novel piezoresistive pressure sensor with a combined cross-beam membrane and peninsula (CBMP) diaphragm structure for micropressure measurements. The sensor is then analyzed through various experiments.

PRESSURE WAVES IN SO-CALLED LOW-PRESSURE HYDROCEPHALUS

The Lancet, 1972
Abstract Episodes of raised intracranial pressure were discovered in patients who were thought to have low-pressure hydrocephalus. Possibly these episodes identify patients in whom continuing deterioration may be expected, and the long-term measurement of intracranial pressure in such patients may be valuable in deciding which of them should have a ...

Nasalance and Nasality in Low Pressure and High Pressure Speech

The Cleft Palate Craniofacial Journal, 1998
Objective This study compared nasalance measures and nasality ratings in low pressure (LP) and high pressure (HP) speech. Subjects The subjects for this study were 25 children ranging in age from 5 to 13 years. Twenty of the subjects were patients followed by a craniofacial team, and five had no history of communication disorder.

High-volume, low-pressure cuffs. Are they always low pressure?

Chest, 1991
Ischemic tracheal complications due to the ETT cuff occur in approximately 10 percent of mechanically ventilated critically ill patients despite the use of high-volume, low-pressure ETT cuffs. Using a laboratory model, we studied the effects of airway pressure on three different ETT cuff designs, including two "low pressure" designs.
