Maneuver Warfare
Maneuver warfare, or manoeuvre warfare, is a military strategy which seeks to shatter the enemy's overall cohesion and will to fight. Background Maneuver warfare, the use of initiative, originality and the unexpected, combined with a ruthless determination to succeed, seeks to avoid opponents' strengths while exploiting their weaknesses and attacking their critical vulnerabilities and is the conceptual opposite of attrition warfare. Rather than seeking victory by applying superior force and mass to achieve physical destruction, maneuver uses preemption, deception, dislocation, and disruption to destroy the enemy's will and ability to fight. Historically, maneuver warfare was stressed by small militaries, the more cohesive, better trained, or more technologically advanced than attrition warfare counterparts. The term "tactical maneuver" is used by maneuver warfare theorists to refer to movement by forces to gain "advantageous position relative to the enemy," as opposed to ...

Valsalva's Maneuver
The Valsalva maneuver is performed by a forceful attempt of exhalation against a closed airway, usually done by closing one's mouth and pinching one's nose shut while expelling air out as if blowing up a balloon. Variations of the maneuver can be used either in medical examination as a test of cardiac function and autonomic nervous control of the heart, or to clear the ears and sinuses (that is, to equalize pressure between them) when ambient pressure changes, as in scuba diving, hyperbaric oxygen therapy, or air travel. A modified version is done by expiring against a closed glottis. This will elicit the cardiovascular responses described below but will not force air into the Eustachian tubes. History The technique is named after Antonio Maria Valsalva, a 17th-century physician and anatomist from Bologna whose principal scientific interest was the human ear. He described the Eustachian tube and the maneuver to test its patency (openness). He also described the use of this m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orbital Maneuver
In spaceflight, an orbital maneuver (otherwise known as a burn) is the use of propulsion systems to change the orbit of a spacecraft. For spacecraft far from Earth (for example those in orbits around the Sun) an orbital maneuver is called a ''deep-space maneuver (DSM)''. The rest of the flight, especially in a transfer orbit, is called ''coasting''. General Rocket equation The Tsiolkovsky rocket equation, or ideal rocket equation is an equation that is useful for considering vehicles that follow the basic principle of a rocket: where a device that can apply acceleration to itself (a thrust) by expelling part of its mass with high speed and moving due to the conservation of momentum. Specifically, it is a mathematical equation that relates the delta-v (the maximum change of speed of the rocket if no other external forces act) with the effective exhaust velocity and the initial and final mass of a rocket (or other reaction engine.) For any such maneuver (or journey involvin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leopold's Maneuvers
In obstetrics, Leopold maneuvers are a common and systematic way to determine the position of a fetus inside the woman's uterus. They are named after the gynecologist Christian Gerhard Leopold. They are also used to estimate term fetal weight. The maneuvers consist of four distinct actions, each helping to determine the position of the fetus. The maneuvers are important because they help determine the position and lie of the fetus, which in conjunction with correct assessment of the shape of the maternal human pelvis, pelvis can indicate whether the delivery is going to be complicated, or whether a caesarean section is necessary. The examiner's skill and practice in performing the maneuvers are the primary factor in whether the fetal lie is correctly ascertained. Alternately, position can be determined by ultrasound performed by a sonographer or physician. Performing the maneuvers Leopold maneuvers are difficult to perform on obese women and women who have polyhydramnios. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerobatic Maneuver
Aerobatic maneuvers are flight paths putting aircraft in unusual attitudes, in air shows, dogfights or competition aerobatics. Aerobatics can be performed by a single aircraft or in formation with several others. Nearly all aircraft are capable of performing aerobatics maneuvers of some kind, although it may not be legal or safe to do so in certain aircraft. Aerobatics consist of five basic maneuvers: * Lines (both horizontal and vertical), * loops, * rolls, * spins, and * hammerheads. Most aerobatic figures are composites of these basic maneuvers with rolls superimposed. A loop is when the pilot pulls the plane up into the vertical, continues around until they are heading back in the same direction, like making a 360 degree turn, except it is in the vertical plane instead of the horizontal. The pilot will be inverted (upside down) at the top of the loop. A loop can also be performed by rolling inverted and making the same maneuver but diving towards the ground. It can be v ...

Military Strategy
Military strategy is a set of ideas implemented by military organizations to pursue desired strategic goals. Derived from the Greek word '' strategos'', the term strategy, when it appeared in use during the 18th century, was seen in its narrow sense as the "art of the general", or "'the art of arrangement" of troops. Military strategy deals with the planning and conduct of campaigns, the movement and disposition of forces, and the deception of the enemy. The father of Western modern strategic studies, Carl von Clausewitz (1780–1831), defined military strategy as "the employment of battles to gain the end of war." B. H. Liddell Hart's definition put less emphasis on battles, defining strategy as "the art of distributing and applying military means to fulfill the ends of policy". Hence, both gave the pre-eminence to political aims over military goals. Sun Tzu (544–496 BC) is often considered as the father of Eastern military strategy and greatly influenced Chinese, Japanese ...

Abdominal Thrusts
Abdominal thrusts, also known as the Heimlich maneuver or Heimlich manoeuvre, is a first aid procedure used to treat upper airway obstructions (or choking) by foreign objects. American doctor Henry Heimlich is often credited for its creation. Performing abdominal thrusts involves a rescuer standing behind a patient and using their hands to exert pressure on the bottom of the diaphragm. This compresses the lungs and exerts pressure on any object lodged in the trachea, hopefully expelling it. Most modern protocols, including those of the American Heart Association, American Red Cross and the European Resuscitation Council, recommend several stages for airway obstructions, designed to apply increasingly more pressure. Most protocols recommend encouraging the victim to cough, followed by hard back slaps, and finally abdominal thrusts or chest thrusts as a last resort. Some guidelines also recommend alternating between abdominal thrusts and back slaps. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalen's Maneuver
Phalen's maneuver is a diagnostic test for carpal tunnel syndrome by an American orthopedist named George S. Phalen. Technique The patient is asked to hold their wrists in complete and forced flexion (pushing the dorsal surfaces of both hands together) for 30–60 seconds. The lumbricals attach in part to the flexor digitorum profundus tendons. As the wrists flex, the flexor digitorum profundus contracts in a proximal direction, drawing the lumbricals along with it. In some individuals, the lumbricals can be "dragged" into the carpal tunnel with flexor digitorum profundus contraction. As such, Phalen's maneuver can moderately increase the pressure in the carpal tunnel via this mass effect, pinching the median nerve between the proximal edge of the transverse carpal ligament and the anterior border of the distal end of the radius. By compressing the median nerve within the carpal tunnel, characteristic symptoms (such as burning, tingling or numb sensation over the thum ...

McRoberts Maneuver
The McRoberts maneuver is an obstetrical maneuver used to assist in childbirth. It is named after William A. McRoberts, Jr. It is employed in case of shoulder dystocia during childbirth and involves hyperflexing the mother's legs tightly to her abdomen. It is effective due to the increased mobility at the sacroiliac joint during pregnancy, allowing rotation of the pelvis and facilitating the release of the fetal shoulder. If this maneuver does not succeed, an assistant applies pressure on the lower abdomen (suprapubic pressure). Current guidelines strongly recommend against pulling on the infants head, as this could lead to brachial plexus injury. Instead, support while keeping the neck straight is indicated. The technique is effective in about 42% of cases. Note that suprapubic pressure and McRobert's maneuver together will resolve 90% of cases.

Müller's Maneuver
Müller's maneuver is a procedure used in medicine to diagnose some types of tinnitus, and other medical problems. Procedure After a forced expiration, an attempt at inspiration is made with closed mouth and nose, whereby the negative pressure in the chest and lungs is made very subatmospheric; the reverse of a Valsalva maneuver. This technique is designed to look for collapsed sections of airways such as the trachea and upper airways. In this maneuver, the patient attempts to inhale with his mouth closed and his nostrils plugged, which leads to a collapse of the airway. Introducing a flexible fiberoptic scope into the hypopharynx to obtain a view, the examiner may witness the collapse and identify weakened sections of the airway. Müller's maneuver is used to help determine the cause of sleep apnea. A positive test result means the site of upper airway obstruction is likely below the level of the soft palate, and the patient will probably not benefit from a uvulopalatopharyngop ...

Credé's Maneuver
The Credé maneuver is a technique used to void urine from the bladder of an individual who, due to disease, cannot do so without aid. The Carl Siegmund Franz Credé, Credé maneuver is executed by exerting manual pressure on the abdomen at the location of the bladder, just below the navel. Patients can learn to perform the maneuver on themselves as it is simple to do. The method is also used in obstetrics to aid the body in expelling the placenta after childbirth.

Sellick Maneuver
Cricoid pressure, also known as the Sellick manoeuvre or Sellick maneuver, is a technique used in endotracheal intubation to try to reduce the risk of regurgitation. The technique involves the application of pressure to the cricoid cartilage at the neck, thus occluding the esophagus which passes directly behind it. Cricoid pressure should not be confused with the "BURP" (Backwards Upwards Rightwards Pressure) manoeuvre, which is used to improve the view of the glottis during laryngoscopy and tracheal intubation, rather than to prevent regurgitation. As the name implies, the BURP manoeuvre requires a clinician to apply pressure on the thyroid cartilage posteriorly, then cephalad (upwards) and, finally, laterally towards the patient's right. History and technique In 1961 Brian Arthur Sellick (1918–1996), an anaesthetist, published the paper ''Cricoid pressure to control regurgitation of stomach contents during induction of anesthesia—preliminary communication'', describing the ...
