The conventional narrative of the Vietnam War often glosses over
the decade leading up to it. Covering the years 1954-1963, this
book presents a thought-provoking reexamination of the war's long
prelude--from the aftermath of French defeat at Dien Bien
Phu--through Hanoi's decision to begin reunification by force--to
the assassination of South Vietnamese President Ngo Dinh Diem.
Established narratives of key events are given critical reappraisal
and new light is shed on neglected factors. The strategic
importance of Laos is revealed as central to understanding how the
war in the South developed.
In the 1970's the National Oceanic and Atmospheric Administration
(NOAA) was made to manage our oceanic and atmospheric resources.
The Southwest Fisheries Science Center is the research arm of
NOAA's Southwest Region. Scientists study all areas from the
Pacific Ocean to the Antarctic to make sure that the ocean and
animals in it stay healthy and safe.
Fuel efficiency of aircraft is of great importance to the military
and private sector. A more efficient wing design for UAVs would
lead to improvements in mission support while reducing fuel costs
for the Air Force. An experimental investigation of one candidate
design, the Houck Aircraft Configuration, has been conducted in the
AFIT low speed wind tunnel. This aircraft shares similarities to
other joined-wing aircraft, but includes curved flow-guides of
varying spanwise camber connecting the upper and lower wingtips.
Experimental results show that the addition of flow guides on the
24" Houck Configuration results in a 2.5% reduction in L/Dmax at Re
H 80K and a 0.3% reduction in L/Dmax at Re H 125K. This trend shows
a decrease in the performance gap as the Reynolds number increases
from 80K to 125K. It is recommended that additional testing at
higher Reynolds numbers be performed to determine if an increase in
performance can be shown. The designed flow guides proved to be
successful in combining the upper and lower wing-tip vortices into
a single vortex. The flow guides alter what would be two smaller
compact vortices and instead produce a slightly larger, spread out
vortex which follows the curve of the flow guide. Ultimately,
evidence of improvements in aerodynamic efficiency will need to be
shown before other claims of the design are demonstrated to be
fully successful.
Arthur Goodzeit Award For seven weeks in 1929, the Republic of
China and the Soviet Union battled in Manchuria over control of the
Chinese Eastern Railroad. It was the largest military clash between
China and a Western power ever fought on Chinese soil, involving
more that a quarter million combatants. Michael M. Walker's The
1929 SinoSoviet War is the first full account of what UPI's Moscow
correspondent called 'the war nobody knew' a 'limited modern war'
that destabilized the region's balance of power, altered East Asian
history, and sent grim reverberations through a global community
giving lip service to demilitarizing in the wake of World War I.
Walker locates the roots of the conflict in miscalculations by
Chiang Kaishek and Chang Hsuehliang about the Soviets' political
and military power-flawed assessments that prompted China's attempt
to reassert full authority over the CER. The Soviets, on the other
hand, were dominated by a Stalin eager to flex some military muscle
and thoroughly convinced that war would win much more than petty
negotiations. This was in fact, Walker shows, a watershed moment
for Stalin, his regime, and his still young and untested military,
disproving the assumption that the Red Army was incapable of
fighting a modern war. By contrast, the outcome revealed how
unprepared the Chinese military forces were to fight either the Red
Army or the Imperial Japanese Army, their other primary regional
competitor. And yet, while the Chinese commanders proved weak,
Walker sees in the toughness of the overmatched infantry a hint of
the rising nationalism that would transform China's troops from a
mercenary army into a formidable professional force, with powerful
implications for an overconfident Japanese Imperial Army in 1937.
Using Russian, Chinese, and Japanese sources, as well as
declassified US military reports, Walker deftly details the war
from its onset through major military operations to its aftermath,
giving the first clear and complete account of a little known but
profoundly consequential clash of great powers between the World
Wars.
