Launched on the same rocket as the RME, the Low-power Atmospheric Compensation Experiment ( LACE ) satellite was built by the United States Naval Research Laboratory ( NRL ) to explore atmospheric distortion of lasers and real-time adaptive compensation for that distortion.

LACE was also used to evaluate ground-based adaptive optics, a technique now used in civilian telescopes to remove atmospheric distortions.

LACE was studied to some extent in the USA during the late 1950s and early 1960s, and by late 1960 Marquardt had a testbed system running.

Meanwhile the main Van Nuys plant was also involved in research into new systems, including a nuclear-powered ramjet for Project Pluto and a liquid air cycle engine ( LACE ) for the Air Force's Aerospaceplane efforts.

This was followed by the liquid air cycle engine ( LACE ) idea which was originally explored by Marquardt and General Dynamics in the 1960s as part of the US Air Force's aerospaceplane efforts.

In an operational setting with LACE, the system was to be placed behind a supersonic air intake which would compress the air through ram compression, then a heat exchanger would rapidly cool it using some of the liquid hydrogen fuel stored on board.

A variety of designs were studied during the lifetime of the project, including most of the early efforts on liquid air cycle engines ( LACE ) and even a nuclear-powered ramjet.

Thus, the advantages, or disadvantages, of the LACE design continue to be a matter of some debate.

Al's Bar, Gorky's, the Atomic Cafe, and LA Contemporary Exhibitions ( LACE ) are some well-known sites.

However, as NASA moved to ballistic capsules during Project Mercury, funding for research into winged vehicles slowly disappeared, and LACE work along with it.

SABRE is an evolution of Alan Bond's series of liquid air cycle engine ( LACE ) and LACE-like designs that started in the early / mid-1980s for the HOTOL project.

A Liquid Air Cycle Engine ( LACE ) is a type of spacecraft propulsion engine that attempts to increase its efficiency by gathering part of its oxidizer from the atmosphere.

By 1959 this work had resulted in the Recoverable Orbital Launch System, or ROLS, based around a LACE engine, known at the time as a Liquid Air Collection System, or LACES.

Technicians at the Naval Research Laboratory ( NRL ), work on the Low-powered Atmosphere Compensation Experiment ( LACE ) satellite.

These sorts of systems have been explored in the LACE concept.

Conceptually LACE works by compressing and then quickly liquefying the air.

The LACE design then blows the compressed air over a heat exchanger, in which the liquid hydrogen fuel is flowing.

One issue with the LACE system is that in order to appreciably reduce the mass of the oxygen carried at launch, a LACE vehicle needs to spend more time in the lower atmosphere to collect enough oxygen to supply the engines.

Hence, much as the costs of using LH2 rather than a hydrocarbon fuel may well outweigh the Isp benefit of using LH2 in a Single-Stage-To-Orbit rocket, the costs of using more LH2 as a propellant and air-liquefaction coolant in LACE may well outweigh the benefits gained by not needing to carry as much LOX on board.

Most significantly, the LACE system is far heavier than a pure rocket engine having the same thrust ( air-breathing engines of almost all types have relatively poor thrust-to-weight ratios compared to rockets ), and the performance of launch vehicles of all types is particularly affected by increases in vehicle dry mass ( such as engines ) that must be carried all the way to orbit, as opposed to oxidizer mass that would be burnt off over the course of the flight.

The most commonly proposed approach is the scramjet, but turborocket, Liquid Air Cycle Engine ( LACE ) and precooled jet engines have also been proposed.

In addition, unlike the LACE concept that preceded it, SABRE ’ s precooler does not liquefy the air letting it run more efficiently.

At Stettin the university-educated artist, who had studied German, was chosen to serve as interpreter and clerk in the office of the Stalag commander.

Observers, in the two school systems studied here, judged the teachers in the structured schools to be more impersonal and demanding, while the atmosphere in the unstructured schools was judged to be more supporting and accepting.

Furthermore, the hydrolysis of paraoxon was studied in mammalian sera, and it was found that it is hydrolyzed by albumin ( or a factor attached to it ) in addition to arylesterase.

His face was still creased in pain as he studied the underside of his arm.

`` That was before I studied law.

Reared in England, she studied to be a teacher, earned several scholarships and was graduated with honors from the University of London.

He was an artisan, a man who studied his trade and developed his craftsmanship the way a goldsmith or a wood carver did.

he studied them, compared them with what he had been taught as a nestling, struggling to bridge between languages, the one he thought with and the one he was learning to think in.

For example, Boas studied immigrant children to demonstrate that biological race was not immutable, and that human conduct and behavior resulted from nurture, rather than nature.

The system was first discovered at the end of the 19th century, and first excavated and studied in the 1970s.

More recent researchers, in particular Ronald Willis and Joy Munns have studied the tour in detail and concluded that the presentation was made after a private cricket match played over Christmas 1882 when the English team were guests of Sir William Clarke, at his property " Rupertswood ", in Sunbury, Victoria.

Cofounder Marc Bloch ( 1886 – 1944 ) was a quintessential modernist who studied at the elite École Normale Supérieure, and in Germany, serving as a professor at the University of Strasbourg until he was called to the Sorbonne in Paris in 1936 as professor of economic history.

The reciprocal influence between the French school and Polish historiography was particularly evident in studies on the Middle Ages and the early modern era studied by Braudel.

Using his excellent knowledge of Greek, which was then rare in the West, to his advantage, he studied the Hebrew Bible and Greek authors like Philo, Origen, Athanasius, and Basil of Caesarea, with whom he was also exchanging letters.

He studied theology and canon law, and after acting as parish priest in his native diocese for twelve years was sent by the pope to Canada as a bishop's chaplain.

Ambros studied at the University of Prague and was well-educated in music and the arts, which were his abiding passion.

The most famous pupil of Ammonius Saccas was Plotinus who studied under Ammonius for eleven years.

He was at the head of the Peripatetic school at Rome, about 58 BC, and was the teacher of Boethus of Sidon, with whom Strabo studied.

" Like his brother Baldwin III, he was more of an academic than a warrior, who studied law and languages in his leisure time: " He was well skilled in the customary law by which the kingdom was governed – in fact, he was second to no one in this respect.
