Resistance movements

Fluidization refers to the condition in which soHd materials are given free-flowing, fluid-like behavior (29). As a gas is passed upward through a bed of sohd particles, the flow of gas produces forces which tend to separate the particles from one another. At low gas flows, the particles remain in contact with other soflds and tend to resist movement. This condition is referred to as a fixed bed. As the gas flow is increased, a point is reached at which the forces on the particles are just sufficient to cause separation. The bed then becomes fluidized. The gas cushion between the soflds allows the particles to move freely, giving the bed a Hquid-like characteristic. 

The friction force between sliding objects resists movement. In this schematic, the block is being moved to the right. 

Other sets of hair cells are formed in specialized parts of the inner ear.964 The three semicircular canals detect angular acceleration in three directions, while the sac-like utricle and saccule detect linear acceleration including gravitational attraction. These two organs each contain a patch of hair cells whose tips project into a gelatinous layer, which is overlain by a field of small crystals of calcium carbonate. These little stones (otoliths) provide an inertial mass, which resists movement causing the hair cell tips to bend and activate mechanoreceptors to send information about balance and orientation to the brain. 

Mechanical Agitation. Devices consisting of a horizontal or vertical shaft with arms may be used to break up material and thereby cause it to flow. However, if the force resisting movement of such devices is large enough it can render the device useless either because of insufficient power to turn it or enough power to cause it to self-destruct. In general, such devices should only be used in relatively small bins and hoppers. 

One reason for this rapid development of the concentration camp system was the spread of active resistance movements, particularly in German-occupied territories. A Polish source remarks in this regard 29... 

The Polish resistance movement, which certainly had no vested interest in whitewashing the conditions in the camp, had the following to say on the food in Majdanek concentration camp in early 1943 53... 

Very often, rumors like this did not arise spontaneously, but were the result of false reports deliberately spread throughout the camps by the resistance movement. That the reports on deliberate mass exterminations in the camps lack any real basis is obvious from the mere fact that the versions spread during the war often failed to accord with the post-war versions in any way. The following is an example. 

The text of the reports spread by the resistance movement relating to mass killings in Auschwitz have been reproduced by Enrique Aynat, Estudios sobre el Holocausto , Graficas Hurtado, Valencia 1994. 

Baum thus generously admits that the reports were resistance movement propaganda . In the next edition, published in 1957, however, he states ... 

Thus, propaganda became publications, by means of which the world was informed Baum was transferred from Auschwitz to Mauthausen, where he assiduously continued his propaganda activity in the local camp resistance movement. 

The suppression of the steam chambers in favor of gas chambers received its impetus from a report of the Jewish-Polish cabinetmaker Jankiel Wiemik, which first appeared in May 1944 in the Polish language but was then translated into English that same year. Wiemik, who according to his statements had been interned in Treblinka for a year and had escaped from there, plagiarized in this text the report of the resistance movement of November 15, 1942, but replaced the steam chambers with gas chambers in every instance and mentioned a motor as the instrument, without, however, specifying that it had been a diesel motor. Evidently he believed - with good reason - that steam as a murder method was all too unbelievable. 

In moving from one location to another, relative to neighboring particles, a particle must surmount a certain potential energy barrier that arises from forces resisting movement. This effect is a function of both particle size and shape and is most... 

The enormous value Acre s extractivists place on the forest is exemplified in the well-documented and highly publicized rubber tapper resistance movement. During the wholesale conversion of forest to pasture during the 1970s and 1980s, many extractivist families in Acre risked their lives when threatened with expulsion from their forested lands (Allegretti 1990, Hecht and Cockburn 1989). Indeed, it was this movement that eventually led to the creation of the first extractive reserves in Acre. Simply stated, deforestation eliminates the resource base from which the extractivist livelihood depends. 

It has been mentioned in section 3.5 on epoxy crack injection systems that epoxies do not do well in wet conditions because they resist movement. Polyurethane resins are suitable for injection of cracks in concrete or masonry in dry or damp conditions. They can be successfully applied in cracks having a width in excess of 0.2 mm. On curing they form an elastic seal impermeable to water. 

The Faculty of Science in Paris had appointed her as a lecturer in 1932, and in 1937 it conferred on her the title of professor. The year before, the French government had named her undersecretary of state for scientific research. In 1938 her research on the action of neutrons on the heavy elements was important in the discovery of uranium fission. The next year, the Legion of Honour inducted her as an officer. During World War II, Frederic led the underground resistance movement as the president of the Front National. 

Italy, in 1919, Primo Levi was trained as a chemist. In 1944, he was arrested as a member of the Italian Anti-Fascist resistance movement and deported to a concentration camp at Auschwitz, Poland. There, his knowledge of chemistry played a pivotal role in keeping his body as well as his spirit intact, as described in his memoirs. Survival in Auschwitz and The Reawakening. After the war, Levi continued to write until his death in Turin in April 1987. 

In 1930 Szent-Gyorgyi returned to Hungary as a professor of medicinal chemistry. He joined the anti-Nazi resistance movement in Hungary during World War II and was for a while exposed to constant danger. He left Hungary in 1947 to join the staff of the Marine Biological Laboratory at Woods Hole, Massachusetts. 

Following Spielman and the aims of this book, our discussion is confined to the capture of particles in liquid suspension from low-speed laminar flows, where the particles are generally small compared with the collector. The two principal transport mechanisms are (a) Brownian diffusion for submicrometer-size particles, and (b) interception of micrometer-size, nondiffusing, inertia free particles with the collector as a consequence of geometrical collision due to particles following fluid streamlines. Inertial impaction, which can be important for gas-borne particles, is usually unimportant for particles in liquids, because the particle—fluid density difference is smaller and the higher viscosity of liquids resists movement relative to the fluid (Spielman 1977). In this section we shall... 

His brother Dietrich, also an opponent of the Nazis, did not fare so well. Dietrich was a theologian of renown as the author of widely acclaimed books and articles on ecumenism. During World War II he was a member of military intelligence but worked secretly for the resistance movement. Dietrich was... 

Fixture rates are defined as the time required for two microscope slides, bonded in a Vi-in. overlap, to resist movement from light finger pressure. Gaps estimated at 1-3 mils. 

Data from mechanical and dielectric measurements can be related, certainly in a qualitative, if not always in a quantitative, way. Formally, the dielectric constant (e ) can be regarded as the equivalent of the mechanical compliance (J ), rather than the modulus, and this highlights the fact that mechanical techniques measure the ability of the system to resist movement, whereas the dielectric approach is a measurement of the ability of the system to move, given that the groups involved must also be dipolar. Interestingly, the dielectric loss (e") appears to match the loss modulus E" or G") more closely than the loss compliance when data are compared for the same system. 

This type of estimate of the major force Fc is useful in the analysis of deflection and vibration problems in machining and in the proper design of work holding devices, because these devices must be able to resist movement and deflection of the part during the process. In general, increasing the speed, the feed, or the depth of cut will increase the power requirement. Doubling the... 

A second major unanswered question is, How should the device mechanically interact with the patient Should it assist movement, resist movement, tune itself to the level of the patient, or simply go along for the ride, measuring the patient s movement. As noted earlier, preliminary clinical results with the ARM Guide suggest that unassisted movement exercise may be as effective as mechanically assisted exercise in promoting movement recoveiy. Other therapy techniques besides assisting in movement have been developed, many of which could be automated. Rehabilitators...
