  3. Biological effects of embedded depleted uranium (DU). Summary of Armed Forces Radiobiology Research Institute research

    International Nuclear Information System (INIS)

    The Persian Gulf War resulted in injuries of US Coalition personnel by fragments of depleted uranium (DU). Fragments not immediately threatening the health of the individuals were allowed to remain in place, based on long-standing treatment protocols designed for other kinds of metal shrapnel injuries. However, questions were soon raised as to whether this approach is appropriate for a metal with the unique radiological and toxicological properties of DU. The Armed Forces Radiobiology Research Institute (AFRRI) is investigating health effects of embedded fragments of DU to determine whether current surgical fragment removal policies remain appropriate for this metal. These studies employ rodents implanted with DU pellets as well as cultured human cells exposed to DU compounds. Results indicate uranium from implanted DU fragments distributed to tissues far-removed from implantation sites, including bone, kidney, muscle, and liver. Despite levels of uranium in the kidney that were nephrotoxic after acute exposure, no histological or functional kidney toxicity was observed. However, results suggest the need for further studies of long-term health impact, since DU was found to be mutagenic, and it transformed human osteoblast cells to a tumorigenic phenotype. It also altered neurophysiological parameters in rat hippocampus, crossed the placental barrier, and entered fetal tissue. This report summarizes AFRRI's depleted uranium research to date

    To assess the overall outcome and success of Fontan surgery at our institute. Patients and Methods: For this retrospective study, institute's cardiac surgery database was used. Patients of single ventricle physiology, who had normal Left Ventricular End-diastolic Pressure and pulmonary artery pressures, were included. Data was analyzed using SPSS version 16. Results: A total of 34 Fontan procedures were done. The mean age at operation was 4.83 +- 1.37 years. There were 22(64.7%) males and 12(35.3%) females. Twenty five (73.5%) had a staged Fontan (successful previous Bidirectional Glenn's shunt, BDG). Nine (26.5%) were primary Fontan procedures (no successful previous Bidirectional Glenn's shunt, BDG). Thirty two (94.8%) were Extra Cardiac Conduit Fontan (ECCF) and 2(5.8%) were Intra Cardiac Fontan. Mean Bypass time was 132.65 +- 48.44 minutes. Aorta was cross clamped in intracardiac Fontan and its mean time was 43.31 +- 5.85 minutes. Fenestration was employed in 14(41.2%) patients. Mean pre-operative oxygen saturations were 77.41 +- 10.27%, which significantly increased to 93.94 +- 3.96 % post-operatively (p<0.001). In-hospital mortality was 2(5.8 %). Conclusion: Fontan surgery has acceptable morbidity and mortality in our set up. (author)

    Established colonies of Anopheles campestris, Anopheles cracens, Anopheles dirus, Anopheles kleini, Anopheles minimus, Anopheles sawadwongporni, and Anopheles sinensis are maintained at the Armed Forces Research Institute of Medical Sciences (AFRIMS). Females were provided blood meals on human blood containing citrate as an anticoagulant using an artificial membrane feeder. The mean wing length, used as an estimate of body size, for each species was compared to blood-feeding duration (time), blood meal volume, and numbers of eggs oviposited. Except for An. campestris and An. cracens, there were significant interspecies differences in wing length. The mean blood meal volumes (mm(3)) of An. kleini and An. sinensis were significantly higher than the other 5 species. For all species, the ratios of unfed females weights/blood meal volumes were similar (range: 0.76-0.88), except for An. kleini (1.08) and An. cracens (0.52), that were significantly higher and lower, respectively. Adult females were allowed to feed undisturbed for 1, 3, and 5min intervals before blood feeding was interrupted. Except for An. campestris and An. sawadwongporni, the number of eggs oviposited were significantly higher for females that fed for 3min when compared to those that only fed for 1min. This information is critical to better understand the biology of colonized Anopheles spp. and their role in the transmission of malaria parasites as they relate to the relative size of adult females, mean volumes of blood of engorged females for each of the anopheline species, and the effect of blood feeding duration on specific blood meal volumes and fecundity.

  14. Optimizing Armed Forces Capabilities for Hybrid Warfare – New Challenge for Slovak Armed Forces

    Directory of Open Access Journals (Sweden)

    Peter PINDJÁK

    2015-09-01

    Full Text Available The paper deals with the optimization of military capabilities of the Slovak Armed Forces for conducting operations in a hybrid conflict, which represents one of the possible scenarios of irregular warfare. Whereas in the regular warfare adversaries intend to eliminate the centers of gravity of each other, most often command and control structures, in irregular conflicts, the center of gravity shifts towards the will and cognitive perception of the target population. Hybrid warfare comprises a thoroughly planned combination of conventional military approaches and kinetic operations with subversive, irregular activities, including information and cyber operations. These efforts are often accompanied by intensified activities of intelligence services, special operation forces, and even mercenary and other paramilitary groups. The development of irregular warfare capabilities within the Slovak Armed Forces will require a progressive transformation process that may turn the armed forces into a modern and adaptable element of power, capable of deployment in national and international crisis management operations.

  15. Proximal arm kinematics affect grip force-load force coordination.

    Science.gov (United States)

    Vermillion, Billy C; Lum, Peter S; Lee, Sang Wook

    2015-10-01

    During object manipulation, grip force is coordinated with load force, which is primarily determined by object kinematics. Proximal arm kinematics may affect grip force control, as proximal segment motion could affect control of distal hand muscles via biomechanical and/or neural pathways. The aim of this study was to investigate the impact of proximal kinematics on grip force modulation during object manipulation. Fifteen subjects performed three vertical lifting tasks that involved distinct proximal kinematics (elbow/shoulder), but resulted in similar end-point (hand) trajectories. While temporal coordination of grip and load forces remained similar across the tasks, proximal kinematics significantly affected the grip force-to-load force ratio (P = 0.042), intrinsic finger muscle activation (P = 0.045), and flexor-extensor ratio (P joint cannot fully explain the observed changes, as task-related changes in intrinsic hand muscle activation were greater than in extrinsic hand muscles. Rather, between-task variation in grip force (highest during task 3) appears to contrast to that in shoulder joint velocity/acceleration (lowest during task 3). These results suggest that complex neural coupling between the distal and proximal upper extremity musculature may affect grip force control during movements, also indicated by task-related changes in intermuscular coherence of muscle pairs, including intrinsic finger muscles. Furthermore, examination of the fingertip force showed that the human motor system may attempt to reduce variability in task-relevant motor output (grip force-to-load force ratio), while allowing larger fluctuations in output less relevant to task goal (shear force-to-grip force ratio).

  16. Gravitoinertial force level influences arm movement control

    Science.gov (United States)

    Fisk, J.; Lackner, J. R.; DiZio, P.

    1993-01-01

    1. The ability to move the forearm between remembered elbow joint angles immediately after rapid increases or decreases of the background gravitoinertial force (G) level was measured. The movements had been well-practiced in a normal 1G environment before the measurements in high-(1.8G) and low-force (0G) environments. The forearm and upper arm were always unsupported to maximize the influence of altered G-loading and to minimize extraneous cues about arm position. 2. Horizontal and vertical movement planes were studied to measure the effects of varying the G load in the movement plane within a given G background. Rapid and slow movements were studied to assess the role of proprioceptive feedback. 3. G level did not affect the amplitude of rapid movements, indicating that subjects were able to plan and to generate appropriate motor commands for the new G loading of the arm. The amplitude of slow movements was affected by G level, indicating that proprioceptive feedback is influenced by G level. 4. The effects of G level were similar for horizontal and vertical movements, indicating that proprioceptive information from supporting structures, such as the shoulder joint and muscles, had a role in allowing generation of the appropriate motor commands. 5. The incidence and size of dynamic overshoots were greater in 0G and for rapid movements. This G-related change in damping suggests a decrease in muscle spindle activity in 0G. A decrease in muscle spindle activity in 0G and an increase in 1.8G are consistent with the results of our prior studies on the tonic vibration reflex, locomotion, and perception of head movement trajectory in varying force backgrounds.

    A novel 6 degrees of freedom (DOFs) wearable exoskeleton arm, ZJUESA, based on man-machine system is presented. It can be used in robot bilateral teleoperation as master arm with force-feedback. With introducing the revolute-prismatic-spherical(RPS) parallel mechanism and planetary gear mechanism, it is designed based on the anatomy of human upper-limb. With the sensors on this external mechanical structure, the human operator motion is detected and converted to the slave robot control command. Additionally the pneumatic system on it generates a force feedback by using hybrid fuzzy control. As a result, the human operator may have a feeling of doing the work directly.

    The Great War had a huge impact on Italian society. The organisation of the armed forces health service faced extreme difficulties due to the extensive loss of life of an almost exclusively terrestrial war. In this context, the role of the medical staff and nursing staff was essential, as the example of the volunteer Red Cross nurses testifies. However, this conflict revealed the need to improve the training of the nursing staff, as was the case in Anglo-Saxon countries.

    1. Forward reaching movements made during body rotation generate tangential Coriolis forces that are proportional to the cross product of the angular velocity of rotation and the linear velocity of the arm. Coriolis forces are inertial forces that do not involve mechanical contact. Virtually no constant centrifugal forces will be present in the background when motion of the arm generates transient Coriolis forces if the radius of body rotation is small. 2. We measured the trajectories of arm movements made in darkness to a visual target that was extinguished as movement began. The reaching movements were made prerotation, during rotation at 10 rpm in a fully enclosed rotating room, and postrotation. During testing the subject was seated at the center of the room and pointed radially. Neither visual nor tactile feedback about movement accuracy was present. 3. In experiment 1, subjects reached at a fast or slow rate and their hands made contact with a horizontal surface at the end of the reach. Their initial perrotary movements were highly significantly deviated relative to prerotation in both trajectories and end-points in the direction of the transient Coriolis forces that had been generated during the reaches. Despite the absence of visual and tactile feedback about reaching accuracy, all subjects rapidly regained straight movement trajectories and accurate endpoints. Postrotation, transient errors of opposite sign were present for both trajectories and endpoints. 4. In a second experiment the conditions were identical except that subjects pointed just above the location of the extinguished target so that no surface contact was involved. All subjects showed significant initial perrotation deviations of trajectories and endpoints in the direction of the transient Coriolis forces. With repeated reaches the trajectories, as viewed from above, again became straight, but there was only partial restoration of endpoint accuracy, so that subjects reached in a straight

    The ability to predict the musculoskeletal response to external loads has multiple applications for the design of machines with a human interface and for the prediction of outcomes of musculoskeletal interventions. In this study, we applied an inverse-inverse dynamics technique to investigate its ability to predict arm posture in response to isometric hand forces. For each subject, we made a three-dimensional musculoskeletal model using the AnyBody Modelling System (AMS). Then, we had each subject-specific model hold a weight anteriorly to the right shoulder joint at a distance of half of the arm length. We selected the glenohumeral abduction angle (GHAA) as the only free parameter. Subsequently, we used inverse-inverse dynamics to find the optimal GHAA that minimised a performance criterion with physiological constraints. In this study, we investigated the performance of two different objective functions: summation of squared muscle activity (SSMA) and summation of squared normalised joint torques (SSNJT). To validate the simulation results, arm posture responses to different isometric downward hand forces were measured for six healthy male subjects. Five trials were performed for each loading condition. The results showed that, with an increase in hand load, there was a reduced GHAA in all subjects. Another interesting finding was that self-selected postures for lighter tasks varied more than postures for heavier tasks for all subjects. To understand this, we investigated the curvature of the objective function as a function of the load and observed an increased curvature with increased load. This may explain the reduced intra-subject variations observed for increasing loads.

    In the article the problems concerning characteristic features of the local wars and armed conflicts, organization bases of construction of The Army and Fleet medical support modern system are discussed. The organization of personnel medical security is considered depending on the duration, intensity and spatial scope of military conflict, peculiarities of group (forces) application and ways of military actions conduction. The distribution of federal troops sanitary losses during the war in Chechenskaya Republic is shown depending on the type, localization and degree of injuries gravity as well as volume of the wounded and invalids evacuation by air transport and work of military medical institutions. The following principles of construction of the Armed Forces medical support system are formulated: The system must be in compliance with troops goals, structure, strategy and tactics, its specificity; development of medical security forms and methods, their historicism; interdependency, completeness and integrity of the system's elements; territorial aspects of its construction and management optimization. Considering character of the goals being laid on the Mobile Forces the paramount importance is attached to the level of readiness of medical service and its formations and units to act in crisis situations.

    Full Text Available Introduction: Because of the dangers in the nature of flight, pilots have to fly in perfect medical conditions. Besides the undesirable effects of the diseases, side effects of the medications used in the treatment might also risk flight safety. In this study, we investigated the drug use attitude of Turkish Armed Forces pilots. Material-Method: In order to investigate their drug use attitude, a questionnaire was given to 408 pilots at GATA Aerospace Medical Center. Drug use attitude, drugs used by pilots and side effects were questioned. Results: 41 % of pilots reported that they used drugs during active flying. But the drug use rate of Army pilots was 57 %, which was higher than the Air Force and Navy pilots. The most common used drugs were analgesics. Conclusion: It is obvious that pilots might use drugs without informing their flight surgeon. Flight surgeons should always educate the pilots about the importance and dangers of self-medication.

    In a previous study, we found the perception of force magnitude to be anisotropic in the horizontal plane. In the current study, we investigated this anisotropy in three dimensional space. In addition, we tested our previous hypothesis that the perceptual anisotropy was directly related to anisotropies in arm dynamics. In experiment 1, static force magnitude perception was studied using a free magnitude estimation paradigm. This experiment revealed a significant and consistent anisotropy in force magnitude perception, with forces exerted perpendicular to the line between hand and shoulder being perceived as 50% larger than forces exerted along this line. In experiment 2, postural arm dynamics were measured using stochastic position perturbations exerted by a haptic device and quantified through system identification. By fitting a mass-damper-spring model to the data, the stiffness, damping and inertia parameters could be characterized in all the directions in which perception was also measured. These results show that none of the arm dynamics parameters were oriented either exactly perpendicular or parallel to the perceptual anisotropy. This means that endpoint stiffness, damping or inertia alone cannot explain the consistent anisotropy in force magnitude perception.

    Full Text Available BACKGROUND: Few studies have examined suicide risk in individuals once they have left the military. We aimed to investigate the rate, timing, and risk factors for suicide in all those who had left the UK Armed Forces (1996-2005. METHODS AND FINDINGS: We carried out a cohort study of ex-Armed Forces personnel by linking national databases of discharged personnel and suicide deaths (which included deaths receiving either a suicide or undetermined verdict. Comparisons were made with both general and serving populations. During the study period 233,803 individuals left the Armed Forces and 224 died by suicide. Although the overall rate of suicide was not greater than that in the general population, the risk of suicide in men aged 24 y and younger who had left the Armed Forces was approximately two to three times higher than the risk for the same age groups in the general and serving populations (age-specific rate ratios ranging from 170 to 290. The risk of suicide for men aged 30-49 y was lower than that in the general population. The risk was persistent but may have been at its highest in the first 2 y following discharge. The risk of suicide was greatest in males, those who had served in the Army, those with a short length of service, and those of lower rank. The rate of contact with specialist mental health was lowest in the age groups at greatest risk of suicide (14% for those aged under 20 y, 20% for those aged 20-24 y. CONCLUSIONS: Young men who leave the UK Armed Forces were at increased risk of suicide. This may reflect preservice vulnerabilities rather than factors related to service experiences or discharge. Preventive strategies might include practical and psychological preparation for discharge and encouraging appropriate help-seeking behaviour once individuals have left the services.

It argues that the higher military leadership in Bishkek shares a common distrust of the Tashkent regime and overall uncertainly about power sharing two months after regime change, while lower level personnel may have provoked the Uzbek minority, because of their nationalist feelings (the majority of police and army personnel are ethnic Kyrgyz and overall frustration with the fragmented political leadership. The situation was further exacerbated by the lack of political control over the security forces and their lack of adequate training to deal with civic unrest.

    Full Text Available The authors propose a comparison between two force-position controllers with gravity compensation simulated on the DEXTER bioinspired robotic arm. The two controllers are both constituted by an internal proportional-derivative (PD closed-loop for the position control. The force control of the two systems is composed of an external proportional (P closed-loop for one system (P system and an external proportional-integrative (PI closed-loop for the other system (PI system. The simulation tests performed with the two systems on a planar representation of the DEXTER, an eight-DOF bioinspired arm, showed that by varying the stiffness of the environment, with a correct setting of parameters, both systems ensure the achievement of the desired force regime and with great precision the desired position. The two controllers do not have large differences in performance when interacting with a lower stiffness environment. In case of an environment with greater rigidity, the PI system is more stable. The subsequent implementation of these control systems on the DEXTER robotic bioinspired arm gives guidance on the design and control optimisation of the arms of the humanoid robot named SABIAN.

    Full Text Available Problem statement: The assistance of person with limited ability of arm movement is necessary for rehabilitation reasons. This aid is required not only to cover the human performances of the arm in motion and force but also to have a strictly stable dynamics. In this study, we proposed a cooperative system between a disabled arm and a robotic manipulator to reach such objectives. Desired positions and contact forces were imposed by the disabled human whereas appropriate torques were applied by the manipulator to follow human intension. Approach: Various control strategies were proposed during recent years to solve position/force control problem. The impedance control concept was used in this study. A relationship between the dynamics of the robot and its energy was developed to derive stability conditions of the robotic system at the constrained motion phase using a suitable Lyapunov approach. Results: New sufficient conditions of asymptotic stability were developed. To prove the efficiency of the proposed approach, a prototype of a human arm coupled to cooperative constrained robotic manipulator was used. The simulation results showed the stability and the performances of the proposed approach. Conclusion: Results showed the possibility of their use in a real context of rehabilitation of injured and disabled people.

    Full Text Available The paper considers a problem pertaining to reduction of the Armed Forces of the Republic of Belarus and necessity to carry out economically reasonable reforms optimizing strength of financial personnel with the purpose to decrease its number but without undermining financial and operational activities of the Armed Forces as a whole. It has been proposed to optimize strength of financial personnel in the Armed Forces while executing organizational staff transformations such as introduction of a centralized accounting system for service personnel by an example of the Ministry of Defense of the Russian Federation.Normative for financial personnel strength of the supposed unified financial centre which is involved in accounting recordings on salary and other payments has been calculated on the basis of inter-branch standards. While taking as an example a conventional organization “B” with staff strength which is equal to the strength of the Armed Forces of the Republic of Belarus the possible efficiency in introduction of the centralized accounting system for service personnel has been determined in the paper. According to represented calculations reduction of financial personnel dealing with accounting recordings on salary and other payments in the whole organization “B” can constitute up to 60 persons with more than 200 branches which are carrying out independent payment accounting for personnel concerned.Dependence of strength normative on number of financial bodies, percentage of personnel receiving payments through a unified financial centre and concentration of financial and economic document circulation has been determined in the paper. It has been pointed out that it is not sufficient to determine quantitative indices in order to ensure an objective reflection of the efficiency of possible introduction of the centralized accounting system for service personnel in the Armed Forces.

    Over the last 10 years, the UK armed forces (UKAF) have been involved in operations worldwide. Mental health in the armed forces (AF) has been the subject of considerable interest in part because of a perceived added risk of psychological distress in this population. Inpatient psychiatric services are provided through partnerships with NHS hospitals. The Cavell Centre, Peterborough's acute inpatient psychiatric unit has up to four beds for service personnel, under the care of a civilian consultant psychiatrist and his AF Foundation Year 2 doctor (F2). This was the only Ministry of Defence (MoD) inpatient unit which had a training post for an AF doctor, but the post ended in August 2014 with the closure of MoD Hospital Unit Peterborough (MDHU(P)). This article outlines the differences in civilian and AF inpatient care and discusses the training value of AF doctors managing service personnel who are psychiatric inpatients.

    2010-07-01

    Biodynamic responses of the hand-arm system have been mostly characterized in terms of driving-point force-motion relationships, which have also served as the primary basis for developing the mechanical-equivalent models. The knowledge of localized vibration responses of the hand-arm segments could help derive more effective biodynamic models. In this study, the transmission of z h-axis handle vibration to the wrist, elbow and the shoulder of the human hand and arm are characterized in the laboratory for the bent-arm and extended arm postures. The experiments involved six subjects grasping a handle subject to two different magnitudes of broad-band random vibration, and nine different combinations of hand grip and push forces. The vibration transmissibility data were acquired in the z h- and y h-axis at the wrist and shoulder, and along all the three axes around the elbow joint. The results show that the human hand-arm system in an extended arm posture amplifies the vibration transmitted to the upper-arm and the whole-body at frequencies below 25 Hz, but attenuates the vibration above 25 Hz more effectively than the bent-arm posture, except at the shoulder. The magnitudes of transmitted vibration under an extended arm posture along the y h-axis were observed to be nearly twice those for the bent-arm posture in the low frequency region. The results further showed that variations in the grip force mostly affect vibration transmissibility and characteristic frequencies of the forearm, while changes in the push force influenced the dynamic characteristics of the entire hand-arm system. The magnitudes of transmitted vibration in the vicinity of the characteristic frequencies were influenced by the handle vibration magnitude.

    We investigated how humans with hereditary cerebellar degeneration [spinocerebellar ataxia (SCA) type 6 and 8, n = 9] and age- and sex-matched healthy controls (n = 9) adapted goal-directed arm movements to an unknown external force field. We tested whether learning could be generalized to untrained regions in the workspace, an aspect central to the idea of an internal model, and if any learning could be retained. After removal of the force field, SCA patients showed little or no learning-related aftereffects indicating that repeated force-field exposure never led to successful force compensation. In contrast, healthy control subjects quickly adapted their movements to the new force field. The difference in force adaptation was significant for movements to targets that required both the shoulder and elbow joint (P < 0.001). Moreover, the generalization of learned movements to targets outside the learned workspace was prevented by the cerebellar degeneration (P < 0.01). Retention of force adaptation was significantly lower in SCA patients (P = 0.003). The severity of ataxia in SCA patients correlated negatively with the extent of learning (r = -0.84, P = 0.004). Our findings imply that progressive loss of cerebellar function gradually impairs force adaptation. The failure to generalize learning suggests that cerebellar degeneration prevents the formation of an internal representation of the limb dynamics. PMID:13679403

    This is an exploratory study of the accurate endpoint force vector production by the human arm in isometric conditions. We formulated three common-sense hypotheses and falsified them in the experiment. The subjects (n=10) exerted static forces on the handle in eight directions in a horizontal plane for 25 seconds. The forces were of 4 magnitude levels (10 %, 20%, 30% and 40% of individual MVC). The torsion moment on the handle (grasp moment) was not specified in the instruction. The two force components and the grasp moment were recorded, and the shoulder, elbow, and wrist joint torques were computed. The following main facts were observed: (a) While the grasp moment was not prescribed by the instruction, it was always produced. The moment magnitude and direction depended on the instructed force magnitude and direction. (b) The within-trial angular variability of the exerted force vector (angular precision) did not depend on the target force magnitude (a small negative correlation was observed). (c) Across the target force directions, the variability of the exerted force magnitude and directional variability exhibited opposite trends: In the directions where the variability of force magnitude was maximal, the directional variability was minimal and vice versa. (d) The time profiles of joint torques in the trials were always positively correlated, even for the force directions where flexion torque was produced at one joint and extension torque was produced at the other joint. (e) The correlations between the grasp moment and the wrist torque were negative across the tasks and positive within the individual trials. (f) In static serial kinematic chains, the pattern of the joint torques distribution could not be explained by an optimization cost function additive with respect to the torques. Plans for several future experiments have been suggested. PMID:23080084

    Full Text Available 2012 has a double significance for this year sees the centenary of the founding of the African National Congress (8 January and of the creation of the Union Defence Forces (1 July, two organisations that have for much of the twentieth century shared a contested history. Yet, in a remarkable bouleversement, South Africa has come through this difficult past and, over the past two decades, a new South African society has been recreated following an interesting period of adjustment following the end of the Cold War and the growth of democracy in the developing world. These changes have necessarily affected her armed forces and the roles defined for them. Some commentators, particularly in the years immediately following 1994, asserted that military power had lost all of its vaunted, Cold-War importance in a new postmodern environment. Others still, recognising future challenges, argued that South Africa, beset with far-reaching socio-economic crises, could no longer afford the burden of military forces. Most scholars agree now that these perspectives were short-sighted and that, while the risk of major conflict has receded, the events of 9/11, and its consequences, demonstrate that the continental and international landscapes are less certain, less stable and less predictable, than that for which many had hoped. Clearly, South African interests are intertwined inextricably in regional and global affairs and if she is to protect these interests and ensure her security, she must maintain credible military force capable of meeting an array of contingencies. It was with this in mind that the strategic arms deal, since the subject of much debate, was passed by parliament:[i] the promise of a full technological transformation, to accompany the human transformation, offered.

  15. Motor adaptation to Coriolis force perturbations of reaching movements: endpoint but not trajectory adaptation transfers to the nonexposed arm

    1. Reaching movements made in a rotating room generate Coriolis forces that are directly proportional to the cross product of the room's angular velocity and the arm's linear velocity. Such Coriolis forces are inertial forces not involving mechanical contact with the arm. 2. We measured the trajectories of arm movements made in darkness to a visual target that was extinguished at the onset of each reach. Prerotation subjects pointed with both the right and left arms in alternating sets of eight movements. During rotation at 10 rpm, the subjects reached only with the right arm. Postrotation, the subjects pointed with the left and right arms, starting with the left, in alternating sets of eight movements. 3. The initial perrotary reaching movements of the right arm were highly deviated both in movement path and endpoint relative to the prerotation reaches of the right arm. With additional movements, subjects rapidly regained straight movement paths and accurate endpoints despite the absence of visual or tactile feedback about reaching accuracy. The initial postrotation reaches of the left arm followed straight paths to the wrong endpoint. The initial postrotation reaches of the right arm had paths with mirror image curvature to the initial perrotation reaches of the right arm but went to the correct endpoint. 4. These observations are inconsistent with current equilibrium point models of movement control. Such theories predict accurate reaches under our experimental conditions. Our observations further show independent implementation of movement and posture, as evidenced by transfer of endpoint adaptation to the nonexposed arm without transfer of path adaptation. Endpoint control may occur at a relatively central stage that represents general constraints such as gravitoinertial force background or egocentric direction relative to both arms, and control of path may occur at a more peripheral stage that represents moments of inertia and muscle dynamics unique to each

    A particular emphasis is put on a novel wearable exoskeleton arm, ZJUESA, with 6 degrees of freedom, which is used for the robot teleoperation with the force-feedback in the unknown environment. In this external structure mechanism, the 3-revolution-prismatic-spherical (3RPS) parallel mechanism is devised from the concept of the human upper-limb anatomy and applied for the shoulder 3-DOF joint. Meanwhile, the orthogonal experiment design method is introduced for its optimal design. Aiming at enhancing the performance of teleoperation, the force feedback is employed by the pneumatic system on ZJUESA to produce the vivid feeling in addition to the soft control interface. Due to the compressibility and nonlinearity of the pneumatic force feedback system, a novel hybrid fuzzy controller for the precise force control is proposed and realized based on the Mega8 microcontroller units as the units of the distributed control system on ZJUESA. With the results of several experiments for master-slave control with force feedback, the feasibility of ZJUESA system and the effect of its hybrid fuzzy controller are verified.

    2015-06-01

    Full Text Available This paper describes the design, development and evaluation tests of an integrated force sensor prototype for portable Coordinate Measuring Arms (CMAs or AACMMs. The development is based on the use of strain gauges located on the surface of the CMAs’ hard probe. The strain gauges as well as their cables and connectors have been protected with a custom case, made by Additive Manufacturing techniques (Polyjet 3D. The same method has been selected to manufacture an ergonomic handle that includes trigger mechanics and the electronic components required for synchronizing the trigger signal when probing occurs. The paper also describes the monitoring software that reads the signals in real time, the calibration procedure of the prototype and the validation tests oriented towards increasing knowledge of the forces employed in manual probing. Several experiments read and record the force in real time comparing different ways of probing (discontinuous and continuous contact and measuring different types of geometric features, from single planes to exterior cylinders, cones, or spheres, through interior features. The probing force is separated into two components allowing the influence of these strategies in probe deformation to be known. The final goal of this research is to improve the probing technique, for example by using an operator training programme, allowing extra-force peaks and bad contacts to be minimized or just to avoid bad measurements.

    While conflict-induced forced migration is a global phenomenon, the situation in Colombia, South America, is distinctive. Colombia has ranked either first or second in the number of internally displaced persons for 10 years, a consequence of decades of armed conflict compounded by high prevalence of drug trafficking. The displacement trajectory for displaced persons in Colombia proceeds through a sequence of stages: (1) pre-expulsion threats and vulnerability, (2) expulsion, (3) migration, (4) initial adaptation to relocation, (5) protracted resettlement (the end point for most forced migrants), and, rarely, (6) return to the community of origin. Trauma signature analysis, an evidence-based method that elucidates the physical and psychological consequences associated with exposures to harm and loss during disasters and complex emergencies, was used to identify the psychological risk factors and potentially traumatic events experienced by conflict-displaced persons in Colombia, stratified across the phases of displacement. Trauma and loss are experienced differentially throughout the pathway of displacement.

    2014-01-01

    We present a detailed study of of a global bifurcation occuring in a turbulent von K\\'arm\\'an swirling flow. In this system, the statistically steady states progressively display hysteretic behaviour when the Reynolds number is increased above the transition to turbulence. We examine in detail this hysteresis using asymmetric forcing conditions --- rotating the impellers at different speeds. For very high Reynolds numbers, we study the sensitivity of the hysteresis cycle --- using complementary Particle Image Velocimetry (PIV) and global mechanical measurements --- to the forcing nature, imposing either the torque or the speed of the impellers. New mean states, displaying multiple quasi-steady states and negative differential responses, are experimentally observed in torque control. A simple analogy with electrical circuits is performed to understand the link between multi-stability and negative responses. The system is compared to other, similar "bulk" systems, to understand some relevant ingredients of nega...

  20. Satellite vehicle tracking aiming to increase traffic safety within the Serbian Armed Forces

    2012-10-01

    Full Text Available The purpose of this work is to show how to affect the most important factor of traffic safety - an individual, by using some technical solutions of satellite tracking of vehicles. By using units of the Land Forces as an example, a brief analysis of traffic safety for vehicles less than 5 years old has been performed. It is noticed that the number of traffic accidents with these vehicles involved has increased, so we tried to use one software package commercially available in order to show all advantages and disadvantages which could be noticed during this kind of vehicle tracking. The conclusion is that preventive vehicle tracking can improve traffic safety, but that a techno-economic analysis has to be done as well, in order to create all the necessary conditions for the introduction of this system in the units of the Serbian Armed Forces.

  1. Etiology and pattern of maxillofacial injuries in the armed forces of pakistan

    International Nuclear Information System (INIS)

    To determine the etiology and pattern of maxillofacial injuries in the Armed Forces of Pakistan in terms of anatomical distribution of injuries. Three hundred consecutive patients of Armed Forces of Pakistan with maxillofacial injuries reporting to AFID and admitted to the hospital or treated as out-patients in the oral surgery clinic, were included in this study. Isolated nasal bone and frontal sinus fractures were excluded from the study. Anatomical distribution, frequency and etiology of fractures, rank at job and occupational as well as personal hobbies were recorded. Descriptive analyses were used to determine mean, standard deviation, percentage and range values. The most frequent bone fractured was the mandible, which accounted for 159 cases (53%). The zygomatic complex was fractured in 51 cases (17%), the maxilla in 12 cases (4 %), and the alveolar process in 21 cases (7%). The most common cause was road traffic accident (168 cases; 56%), followed by accidental fall (69 cases; 23%), gunshot injuries (27 cases; 9%), sports related injuries (15 cases; 5%), and injury associated with a fight (12 cases; 4%); there were only 9 cases of animals related injuries (3%). In this series, mandible was the most commonly fractured facial bone, while road traffic accident was the most common etiological factor. Results could be influenced by the personal and working environment. (author)

  2. Conducting qualitative research in the British Armed Forces: theoretical, analytical and ethical implications.

    Finnegan, Alan

    2014-06-01

    The aim of qualitative research is to produce empirical evidence with data collected through means such as interviews and observation. Qualitative research encourages diversity in the way of thinking and the methods used. Good studies produce a richness of data to provide new knowledge or address extant problems. However, qualitative research resulting in peer review publications within the Defence Medical Services (DMS) is a rarity. This article aims to help redress this balance by offering direction regarding qualitative research in the DMS with a focus on choosing a theoretical framework, analysing the data and ethical approval. Qualitative researchers need an understanding of the paradigms and theories that underpin methodological frameworks, and this article includes an overview of common theories in phenomenology, ethnography and grounded theory, and their application within the military. It explains qualitative coding: the process used to analyse data and shape the analytical framework. A popular four phase approach with examples from an operational nursing research study is presented. Finally, it tackles the issue of ethical approval for qualitative studies and offers direction regarding the research proposal and participant consent. The few qualitative research studies undertaken in the DMS have offered innovative insights into defence healthcare providing information to inform and change educational programmes and clinical practice. This article provides an extra resource for clinicians to encourage studies that will improve the operational capability of the British Armed Forces. It is anticipated that these guidelines are transferable to research in other Armed Forces and the military Veterans population.

Due to the disuse of the arms, passive joint stiffness increases and providing only gravity compensation becomes insufficient to support the arm function. Hence, joint stiffness compensation is also

  5. A comparative study of the active force control schemes applied to robot arm

    International Nuclear Information System (INIS)

    In this paper, a comparative study of three different types of active force control (AFC) schemes applied to a robotic arm is described. The study particularly focuses on the techniques to compute the estimated inertia matrix (ΙΝ) of a robotic manipulator necessary for the execution of the AFC strategy since the computation of (ΙΝ) is the common central theme to all AFC-based schemes. The first of the three AFC schemes is based on the conventional method of obtaining (ΙΝ), the second uses artificial neural network while the third incorporates an iterative learning algorithm. The study also discusses the characteristics of the (ΙΝ) curves obtained, the trajectory track performance of the schemes and the effects of the modelled disturbances. The robustness of all the AFC schemes are also ascertained in the study. (Author)

    2013-02-01

    This report summarizes incidence rates of the five most commonly diagnosed sexually transmitted infections (STIs) among active component service members of the U.S. Armed Forces during 2000 to 2012. Human papillomavirus (HPV) infections were the most common, followed in decreasing order of frequency by infections associated with chlamydia, herpes simplex virus, gonorrhea, and syphilis. Compared to their counterparts, women, younger service members, soldiers, and enlisted members had higher incidence rates of each STI. Rates tended to be lower among married personnel. Rates of chlamydia, HPV, and gonorrhea diagnoses were notably higher among women during 2006 to 2008 but rates of the latter two infections have since declined sharply. The relatively recent introduction of STI screening among young service women and the HPV vaccine are discussed.

    The fluid dynamics of cephalopods has so far received little attention in the literature, due to their complexity in structure and locomotion. The flow around octopuses, in particular, can be complicated due to their agile and dexterous arms, which frequently display some of the most diverse mechanisms of motion. The study of this flow amounts to a specific instance of the hydrodynamics problem for rough tapered cylinder geometries. The outstanding manipulative and locomotor skills of octopuses could inspire the development of advanced robotic arms, able to operate in fluid environments. Our primary aim was to study the hydrodynamic characteristics of such bio-inspired robotic models and to derive the hydrodynamic force coefficients as a concise description of the vortical flow effects. Utilizing computational fluid dynamic methods, the coefficients were computed on realistic morphologies of octopus-like arm models undergoing prescribed solid-body movements; such motions occur in nature for short durations in time, e.g. during reaching movements and exploratory behaviors. Numerical simulations were performed on translating, impulsively rotating, and maneuvering arms, around which the flow field structures were investigated. The results reveal in detail the generation of complex vortical flow structures around the moving arms. Hydrodynamic forces acting on a translating arm depend on the angle of incidence; forces generated during impulsive rotations of the arms are independent of their exact morphology and the angle of rotation; periodic motions based on a slow recovery and a fast power stroke are able to produce considerable propulsive thrust while harmonic motions are not. Parts of these results have been employed in bio-inspired models of underwater robotic mechanisms. This investigation may further assist elucidating the hydrodynamics underlying aspects of octopus locomotion and exploratory behaviors.

    2001-03-23

    A classical visuo-manual adaptation protocol carried out on a rotating platform was used to test the ability of subjects to adapt to centrifugal and Coriolis forces when visual feedback of the arm is manipulated. Three main results emerge: (a) an early modification of the initial trajectory of the movements takes place even without visual feedback of the arm; (b) despite the change in the initial trajectory, the new external force decreases the accuracy of the pointing movements when vision is precluded; (c) a visual adaptive phase allows complete adaptation of the pointing movements performed in a modified gravitoinertial field. Therefore vision would be essential for subjects to completely adapt to centrifugal and Coriolis forces. However, other sensory signals (i.e. vestibular and proprioceptive) may constitute the basis for early but partial correction of the pointing movements.

    2015-12-01

    The Department of Energy Atmospheric Radiation Measurement (ARM) Program is developing a routine large-eddy simulation (LES) modeling framework at the ARM Climate Research Facility sites, known as the "LES ARM Symbiotic Simulation and Observation" (LASSO) Workflow. The routine simulations will be assessed using comprehensive ARM observations of the atmosphere and land-surface states, particularly cloud observations. Since small changes in thermodynamic profiles can manifest large changes in cloud properties, successful simulations require careful initialization, appropriate forcing, and possibly suitable lateral boundary conditions. We use a multiscale data assimilation (MS-DA) system as a major methodology for producing forcing datasets required by the LES modeling. The MS-DA will be implemented in the regional Weather Research and Forecasting (WRF) model at a cloud resolving resolution (~1 km). MS-DA leverages existing reanalyses (e.g., the NCEP North American Regional Reanalysis, NARR) and operational forecasting products (e.g. the North American Mesoscale Forecast System, NAM; the High-Resolution Rapid Refresh, HRRR) products, and takes advantage of ARM observations to directly constrain the spectra of horizontal scales down to a few km. The analysis from the MS-DA allows deriving initial conditions and forcing datasets for a range of spatial and temporal scales, developing hydrometeor forcing, exploring time-varying boundary conditions, and diagnosing other needed thermodynamic variables. It is stressed that the datasets from the MS-DA are integrated with datasets from other sources to form ensembles to account for uncertainties. The methodologies, implementation and evaluations are presented.

    International Nuclear Information System (INIS)

    To determine the frequency of risk factors of coronary artery disease (CAD) in apparently healthy soldiers of Pakistan Armed Forces. Study Design: Cross sectional descriptive study. Place and Duration of Study: Department of medicine, CMH Okara from July 2012 to Dec 2012. Patients and Methods: The study included 2215 male currently serving soldiers in age range of 18 to 52 years by consecutive sampling. Relevant history, body mass index (BMI), waist circumference (WC) and blood pressure (BP) of each subject were recorded. BMI > 25 kg/m/sup 2/ and WC > 90 cm was considered obesity and abdominal obesity respectively. BP > 140/90 mmHg was defined as hypertension. All the participants of study underwent blood glucose fasting, blood glucose random, ECG recording, personality assessment and lipid profile. Risk estimation was done using Eric Brittain scoring system. Results: In our study group 95.5% patients were having at least 1 risk factor of CAD, 54 % were having 2 to 4 risk factors while 3.93% had > 4 risk factors. Risk estimation of CAD using Eric Brittain scoring system showed that a large proportion of study group had high probability of developing ischemic heart disease in next 6 years. Conclusion: A large proportion of our soldiers are harboring risk of CAD due to increase in frequency of 8 conventional CAD risk factors especially obesity. (author)

    2015-06-01

    There is an integral connection between leadership, mentoring and professional career progression within the nursing profession. The purpose of this article is to examine recommendations and best practices from the literature and provide a basis to construct a formalized successful mentoring dyad program with guidelines on establishing and maintaining a productive mentoring relationship over long distance. Canadian Armed Forces (CAF) nurses practice within a unique domain both domestically and abroad. The military environment incorporates many aspects of mentoring that could benefit significantly by distance interchange. Supported through examining literature within nursing, CAF publications and other professions along with contrasting successful distance mentoring programs, the findings suggest that a top-down, leadership-driven formal mentoring program could be beneficial to CAF nurses. The literature review outlines definitions of terms for mentorship and distance mentoring or e-mentoring. A cross section of technology is now embedded in all work environments with personal communication devices commonplace. Establishing mentoring relationships from afar is practical and feasible. This article provides a guided discussion for nursing leaders, managers and grassroots nurses to implement mentoring programs over distances. The recommendations and findings of this article could have universal applications to isolated nursing environments outside of Canadian military operational frameworks. PMID:26560257

    Full Text Available The Revolutionary Armed Forces of Colombia (FARC have been one of the world's most consistently formidable violent non-state actors over the last forty years. Unsurprisingly, the group has provided one of the most compelling and concerning examples of the level of technical sophistication attainable by sub-state organizations. Over the last two decades the group has carried out an iterative and innovative process that, in reaction to improved detection capabilities, has brought them from depending on disposable go-fast boats to transport drugs to possessing fully submersible and reusable covert vessels for transportation. The following case study will discuss the development of narco-submarines and the underlying motivations behind the pursuit of this complex engineering task. The case study will outline the different phases of the narco-submarine development and highlight FARC’s determination to overcome the challenges present in each design. This discussion will show how FARC’s systematized acquiring of information and expertise has resulted in the accomplishment of fully submersible vessels, capable of transporting more than 10 tons of illicit product.

    Full Text Available This paper, through the narratives of activists and Meira Paibis reiterates the slogan—repeal the Armed Forces Special Powers Act (AFSPA, which is draconian and anti-people in spirit. The atroci- ty, which has been meted out on the people of Manipur because of this Act, is a profound viola- tion of human rights. Rape, mindless killings, kidnapping, fake encounters have been normalised by virtue of this Act. The youths have been badly affected due to the conflict emerging out of this Act which treats people in Manipur as ‘objects’ against the imagined boundaries of the Indian na- tion-state for security from the neighbouring nations. In this process, the lived experiences of the people have been pushed to the periphery against the massive motive of the state to protect bor- ders and the imagined nation, which is a direct offshoot of the legacy of colonialism in India. The paper has tried to capture the history of Manipur on a capsule to concretise the struggle of Irom Sharmila and the ‘hopes’ she gives to the people of Manipur for ‘peace’ and ‘justice’. Alongside, it makes a humble attempt to describe the ‘life’ of Irom Sharmila. In addition, it describes the rage of Manipuris, which have given rise to insurgency asking for ‘freedom’ through various platforms.

  4. A New Crank Arm-Based Load Cell for the 3D Analysis of the Force Applied by a Cyclist

    Directory of Open Access Journals (Sweden)

    Alexandre Balbinot

    2014-12-01

    Full Text Available This report describes a new crank arm-based force platform designed to evaluate the three-dimensional force applied to the pedals by cyclists in real conditions. The force platform was designed to be fitted on a conventional competition bicycle crankset while data is transmitted wirelessly through a BluetoothTM module and also stored on a SD card. A 3D solid model is created in the SolidWorks (Dassault Systèmes SOLIDWORKS Corp. to analyze the static and dynamic characteristics of the crank arm by using the finite elements technique. Each crankset arm is used as a load cell based on strain gauges configured as three Wheatstone bridges. The signals are conditioned on a printed circuit board attached directly to the structure. The load cell showed a maximum nonlinearity error between 0.36% and 0.61% and a maximum uncertainty of 2.3% referred to the sensitivity of each channel. A roller trainer equipped with an optical encoder was also developed, allowing the measurement of the wheel’s instantaneous velocity.

    2003-01-01

    Objective: To assess the incidence, types and risk factors of military training-related injuries in recruits of Chinese People's Armed Police Forces (CPAPF). Methods: A cohort study was made on the risk factors of injuries in 805 male recruits during the military training from December 25, 1999 toDecember 25, 2000. Results: A total of 111 recruits (14%) experienced one or more injuries, and the cumulative incidence was 16.1 injuries per 100 soldiers in a year. And 77.7% of the injuries belonged to overuse injuries of the skeletal and muscular systems, the most common type of which was stress fractures. Most injuries occurred in the 3rd month of training. Univariate analysis and logistic regression analysis of possible risk factors for overuse injuries were carried out, and a number of risk factors were identified: history of agricultural labor, history of lower limb injury, flatfoot and less running exercise before entry into the army. But a suitable body mass index (BMI) was a protective factor. Examination of age, body height, smoking, body flexibility and frequency of 2-mile running revealed no significant association with the injuries. Conclusions: History of agricultural labor, history of lower limb injury, flatfoot, less running exercise before entry into the army and lower BMI were risk factors of the overuse injuries. In order to decrease the incidence of overuse injuries, the young people with good physical ability and shapely body type should be selected during conscription. During the training, nutrition should be improved so as to decrease the incidence of injuries.

    In the German Armed Forces sports activities should bring the benefits of good health and trained fitness which are the hallmarks of sportsmen. In order to achieve this aim it is important to avoid accidents which negate the benefit of sports. Until today there appear to be no studies in existence which demonstrate the risk factors of sports activities undertaken while in military service. Equivalent studies on civilian sport activities are scarcely comparable. To find out risk factors for accidents with any period of recovery we followed sports accidents while on duty in a German barracks with 4,300 soldiers over a two-year period. Additionally we asked about the time needed for recovery from each accident, parameters of lifestyle, the body mass index and the possibility of a nightshift before each accident. We examined a minimum of 410 accidents. We found associations between the accidents studied and particular risk factors, including doing sports more than two times a week, being active in a fitness or sports club, having the accident together with another sportsman and doing a nightshift before the day of the accident. Bad ground conditions contributed to a large number of accidents. A body mass index of 25 and higher had a significantly prolonged time for recovery. To avoid accidents, sport and ground conditions should be adapted to each other. In addition, overweight people are not only compromised for cardiovascular and neurological diseases but also have a higher risk of needing a prolonged time for recovery, thus it is important that overweight should be avoided and not only just be treated.

    Military fitness is defined as a hierarchical 4-level construct in the German armed forces: (a) "Fundamental/Baseline Fitness," (b) "Basic Military Fitness," (c) "Task Fitness," and (d) "Mission Fitness." "Fundamental/Baseline Fitness" is assessed with the "Basic Fitness Test." However, this test alone is not sufficient to assess readiness for the physical demands of deployments. The first part of the article describes the development of a tool mirroring the specific physiological requirements of military operations on a joint forces level. The "Basic Military Fitness Tool" (BMFT) combines 4 crucial military demands into one single timed test run performed with field uniform (5 kg), body armor (13.4 kg), and helmet (1.6 kg): (a) maneuver under fire: 130 m run with changes in direction, velocity, and body position, (b) casualty rescue: 40 m of dragging a 50 kg load, (c) load carrying: 100 m carrying of two 18 kg loads, and (d) load lifting: lifting a 24 kg load on to a 1.25 m high rack 5 times. The second part covers the first assessment of BMFT selectivity between high- and low-performing groups. Muscle mass and strength are important factors for working with loads. Thus, female soldiers are expected to need more time to complete BMFT because of their on average lower muscle mass. Eighteen female (age = 28.5 ± 6.6 years, lean body mass [LBM] = 45.0 ± 4.5 kg; mean ± SD) and 104 male soldiers (age = 30.0 ± 8.4, LBM = 64.3 ± 7.1) completed isometric strength testing (hand grip = 344.3 ± 51.4 N and 547.3 ± 79.1 N, elbow flexors = 118.9 ± 16.9 and 235.1 ± 42.0, knee extensors = 433.2 ± 87.4 and 631.4 ± 111.4) and BMFT (259.2 ± 44.0 and 150.0 ± 21.1 s). Except age, all variables differed significantly (p < 0.01) between groups.

  11. Unsteady hydrodynamic forces acting on a robotic arm and its flow field: application to the crawl stroke.

    2014-04-11

    This study aims to clarify the mechanisms by which unsteady hydrodynamic forces act on the hand of a swimmer during a crawl stroke. Measurements were performed for a hand attached to a robotic arm with five degrees of freedom independently controlled by a computer. The computer was programmed so the hand and arm mimicked a human performing the stroke. We directly measured forces on the hand and pressure distributions around it at 200 Hz; flow fields underwater near the hand were obtained via 2D particle image velocimetry (PIV). The data revealed two mechanisms that generate unsteady forces during a crawl stroke. One is the unsteady lift force generated when hand movement changes direction during the stroke, leading to vortex shedding and bound vortex created around it. This bound vortex circulation results in a lift that contributes to the thrust. The other occurs when the hand moves linearly with a large angle of attack, creating a Kármán vortex street. This street alternatively sheds clockwise and counterclockwise vortices, resulting in a quasi-steady drag contributing to the thrust. We presume that professional swimmers benefit from both mechanisms. Further studies are necessary in which 3D flow fields are measured using a 3D PIV system and a human swimmer.

    In 2013, the Canadian Armed Forces (CAF) implemented the Fitness for Operational Requirements of Canadian Armed Forces Employment (FORCE), a field expedient fitness test designed to predict the physical requirements of completing common military tasks. Given that attaining this minimal physical fitness standard may not represent a challenge to some personnel, a fitness incentive program was requested by the chain of command to recognize and reward fitness over and above the minimal standard. At the same time, it was determined that the CAF would benefit from a measure of general health-related fitness, in addition to this measure of operational fitness. The resulting incentive program structure is based on gender and 8 age categories. The results on the 4 elements of the FORCE evaluation were converted to a point scale from which normative scores were derived, where the median score corresponds to the bronze level, and silver, gold, and platinum correspond to a score which is 1, 2, and 3 SDs above this median, respectively. A suite of rewards including merit board point toward promotions and recognition on the uniform and material rewards was developed. A separate group rewards program was also tabled, to recognize achievements in fitness at the unit level. For general fitness, oxygen capacity was derived from FORCE evaluation results and combined with a measure of abdominal circumference. Fitness categories were determined based on relative risks of mortality and morbidity for each age and gender group. Pilot testing of this entire program was performed with 624 participants to assess participants' reactions to the enhanced test, and also to verify logistical aspects of the electronic data capture, calculation, and transfer system. The newly dubbed fitness profile program was subsequently approved by the senior leadership of the CAF and is scheduled to begin a phased implementation in June 2015. PMID:26506187

    In this paper,the practicality and feasibility of Active Force Control (AFC) integrated with Fuzzy Logic(AFCAFL) appliedto a two link planar arm actuated by a pair of Pneumatic Artificial Muscle (PAM) is investigated.The study emphasizes on the application and control of PAM actuators which may be considered as the new generation of actuators comprising fluidic muscle that has high-tension force,high power to weight ratio and high strength in spite of its drawbacks in the form of high nonlinearity behaviour,high hysteresis and time varying parameters.Fuzzy Logic (FL) is used as a technique to estimate the best value of the inertia matrix of robot arm essential for the AFC mechanism that is complemented with a conventional Proportional-Integral-Derivative (PID) control at the outermost loop.A simulation study was first performed followed by an experimental investigation for validation.The experimental study was based on the independent joint tracking control and coordinated motion control of the arm in Cartesian or task space.In the former,the PAM actuated arm is commanded to track the prescribed trajectories due to harmonic excitations at the joints for a given frequency,whereas for the latter,two sets of trajectories with different loadings were considered.A practical rig utilizing a Hardware-In-The-Loop Simulation (H1LS) configuration was developed and a number of experiments were carried out.The results of the experiment and the simulation works were in good agreement,which verified the effectiveness and robustness of the proposed AFCAFL scheme actuated by PAM.

    2014-01-01

    This study examined changes in the propulsive force and stroke parameters of arm-amputee and able-bodied swimmers during tethered swimming. Eighteen well-trained female swimmers (nine unilateral arm amputees and nine able-bodied) were videotaped performing maximal-effort 30 s front-crawl swims, while attached to a load cell mounted on a pool wall. Tether force, stroke rate, stroke phase durations and inter-arm angle were quantified. The able-bodied group produced significantly higher mean and maximum tether forces than the amputee group. The mean of the intra-cyclic force peaks was very similar for both groups. Mean and maximum tether force had significant negative associations with 100 m swim time, for both groups. Both groups exhibited a similar fatigue index (relative decrease in tether force) during the test, but the amputees had a significantly greater stroke rate decline. A significant positive association between stroke rate decline and fatigue index was obtained for the able-bodied group only. Inter-arm angle and relative phase durations did not change significantly during the test for either group, except the recovery phase duration of the arm amputees, which decreased significantly. This study's results can contribute to the development of a more evidence-based classification system for swimmers with a disability.

    Full Text Available The Point of Departure: The Military Transfer Concept A cursory examination of the literature now available on the South African Defence Force would suggest that such literature contains an embarrassment of riches. A more careful scrutiny, however, suggests that. in terms of nominal measurement. it can be grouped into fairly discrete categories covering the first (1880-1881 and second (1899-1902 Anglo-Boer Wars, World Wars I and II, the Korean conflict. and the growth of the South African Defence Force as a natural complement to the world isolation engendered by the pursuit of the policy of apartheid. The last category is more appropriately considered as part of the civil-military and foreign policy history of the Republic of South Africa because of the severance of the Commonwealth tie in 1961 and the declaration of the arms embargo against the Republic in 1963.

    A possible mechanism by which disodium cromoglycate (DSCG) prevents a decrease in regional cerebral blood flow but not hypotension in primates following whole body gamma irradiation was studied. Several studies have implicated superoxide radicals in intestinal and cerebral vascular disorders following ischemia and ionizing radiation, respectively, The superoxide radical is formed during radiolysis in the reaction between hydrated electrons and dissolved oxygen. For this reason, the efficiency of DSCG to scavenge hydrated electrons and possibly prevent the formation of the superoxide radical was studied. The results show that DSCG is an efficient hydrated-electrons scavenger and may effectively compete with oxygen for hydrated electrons preventing the radiolytic formation of the superoxide radicals.

  4. Forced arm use is superior to voluntary training for motor recovery and brain plasticity after cortical ischemia in rats

    Science.gov (United States)

    2014-01-01

    Background and purpose Both the immobilization of the unaffected arm combined with physical therapy (forced arm use, FAU) and voluntary exercise (VE) as model for enriched environment are promising approaches to enhance recovery after stroke. The genomic mechanisms involved in long-term plasticity changes after different means of rehabilitative training post-stroke are largely unexplored. The present investigation explored the effects of these physical therapies on behavioral recovery and molecular markers of regeneration after experimental ischemia. Methods 42 Wistar rats were randomly treated with either forced arm use (FAU, 1-sleeve plaster cast onto unaffected limb at 8/10 days), voluntary exercise (VE, connection of a freely accessible running wheel to cage), or controls with no access to a running wheel for 10 days starting at 48 hours after photothrombotic stroke of the sensorimotor cortex. Functional outcome was measured using sensorimotor test before ischemia, after ischemia, after the training period of 10 days, at 3 and 4 weeks after ischemia. Global gene expression changes were assessed from the ipsi- and contralateral cortex and the hippocampus. Results FAU-treated animals demonstrated significantly improved functional recovery compared to the VE-treated group. Both were superior to cage control. A large number of genes are altered by both training paradigms in the ipsi- and contralateral cortex and the hippocampus. Overall, the extent of changes observed correlated well with the functional recovery obtained. One category of genes overrepresented in the gene set is linked to neuronal plasticity processes, containing marker genes such as the NMDA 2a receptor, PKC ζ, NTRK2, or MAP 1b. Conclusions We show that physical training after photothrombotic stroke significantly and permanently improves functional recovery after stroke, and that forced arm training is clearly superior to voluntary running training. The behavioral outcomes seen correlate with

    As of early January 2005, the French Armed Forces Health Services were on the ground in Indonesia to contribute to relief operations following the tsunami in Indonesia on December 26, 2004. Findings of preliminary investigation performed upon deployment of the first French elements demonstrated that a major priority was to speed up vaccination against measles in children between the ages of 6 months and 15 years. A vaccination campaign was planned in cooperation with Indonesian authorities and UNICEF. Implementation involved training of personnel and setting up vaccination clinics in refugee camps, schools, and neighborhoods in the city of Meulaboh. The vaccination campaign was hampered by a number of problems in particular involving logistics and required constant supervision. A survey to evaluate the results of the campaign in terms of vaccination coverage showed that the objective of vaccinating 70% of children in refugee camps was achieved. The survey provided other child health indicators that will be helpful to local authorities taking over after the departure of the French Armed Forces Health Services. PMID:16038345

    This paper describes a mechanical technique to reduce the nozzle reaction force of a sandblasting rig. A theoretical evaluation of the magnitudes and direction of action of typical sandblasting nozzle forces has been conducted and a technique for exploiting available energy in order to reduce the magnitude of the forces at the nozzle has been developed.Experimental results from a variety of tests in different configurations have confirmed the theoretically determined force magnitude's accuracy and shown that forces of up to 106N can be present in typical sandblasting operations. The results have also shown that an up to 77% reduction of force at the nozzle can be achieved by applying the developed mechanicaltechnique.

    The report provides a basis for the Armed Forces long-term planning, and how changes in the global energy supply may mean new challenges and threats, as well as the advantages and disadvantages that can be associated with different future energy solutions for Armed Forces own activities, primarily relating to fuel and power during operation. One conclusion is that the potential conflict between energy security and climate-security can lead to far-reaching security implications and that continued global fossil dependency contributes to increased safety of political and military focus on a number of potential conflicts. A new such area may be the Arctic, as in the wake of climate change will become available for exploitation. Large scale global renewable energy can bring greater geographical spread - and reduced pressure on existing 'hot-spots'. Nuclear power is unlikely to be influential in the overall global energy security, but security problems associated with the production of nuclear materials can spread and be strengthened. Furthermore, the energy problems of connected to gaps between rich and poor, which may lead to social friction and conflict. The trend toward increased nationalisation and politicization of the energy is in contrast to free trade and market liberalism and may lead to further militarization of energy resources. Bilateral energy contracts may result in division within the EU and create a hindrance to joint positions and actions, such as in international efforts. As for Armed Forces own future energy solutions, the knowledge of alternative fuels (eg alcohols, diesel variants, gaseous fuels) and energy converters (eg hybrid vehicles, fuel cells) is reviewed. The following alternative principle solutions fuel and power are discussed: 1. Power from small-scale electricity generation via solar cells and small wind farms and power stations with liquid fuel as a supplement. Transport with plug-in hybrid vehicles, i.e. liquid propellants in

    The history of interprofessional education (IPE) in the USA is a checkered one, characterized by boom and bust cycles of advancement and retrenchment, expansion and contraction. The successful development, implementation and continuation of IPE in health and social care in US higher education institutions all depend on a number of factors related to how individuals and organizations do or do not support it in the academic setting. Deliberate and planned change to advance IPE requires a comprehensive theoretical framework to guide it and insure its success. A transtheoretical model (TTM) of institutional change is proposed as a comprehensive framework of the stages, processes and forces that can facilitate and maintain change in support of IPE. The TTM framework recognizes the complexity of change, and captures and organizes important elements from different organizational theories. It also provides a structure for conceptualizing the multiple dimensions needed for change, offering intervention strategies and leverage points to be used by leaders in promoting and maintaining it. Finally, the TTM model suggests that the stabilization of IPE programs over the long term is dependent on a real and significant shift in institutional values in response to forces from both within and without the organization.

    French military personnel are subject to a compulsory vaccination schedule. The aim of this study was to describe vaccine adverse events (VAE) reported from 2002 to 2010 in armed forces. VAE are routinely surveyed by the military Centre for epidemiology and public health. For each case, military practitioners fill a notification form, providing patient characteristics, clinical information and vaccines administered. For this study, VAE following influenza A(H1N1)pdm09 vaccination were excluded. Among the 473 cases retained, 442 (93%) corresponded to non-severe VAE,including local, regional and systemic events, while 31 corresponded to severe VAE, with two leading to significant disability. The global VAE reporting rate (RR) was 14.0 per 100,000 injections. While stationary from 2002 to 2008, the RR increased from 2009. The most important observations were a marked increase of VAE attributed to Bacillus Calmette-Guérin (BCG) vaccine from 2005 to 2008, a high RR observed with the inactivated diphtheria-tetanus (toxoids)-poliovirus vaccine combined with acellular pertussis vaccine (dTap-IPV) from 2008 and an increase in RR for seasonal influenza vaccine VAE in 2009. Our RR for severe VAE (1.1 VAEper 100,000) appears comparable with rates observed among United States civilians and military personnel. The increase observed from 2009 could be partly explained by the influenza A(H1N1)pdm09 pandemic which increased practitioner awareness towards VAE. In conclusion, the tolerance of the vaccines used in French armed forces appears acceptable.

    Data collected at the Department of Energy Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) Central Facility (SCF) are analyzed to determine the monthly and hourly variations of cloud fraction and radiative forcing between January 1997 and December 2002. Cloud fractions are estimated for total cloud cover and for single-layered low (0-3 km), middle (3-6 km), and high clouds (more than 6 km) using ARM SCG ground-based paired lidar-radar measurements. Shortwave (SW) and longwave (LW) fluxes are derived from up- and down-looking standard precision spectral pyranometers and precision infrared radiometer measurements with uncertainties of approximately 10 Wm(exp -2). The annual averages of total, and single-layered low, middle and high cloud fractions are 0.49, 0.11, 0.03, and 0.17, respectively. Both total and low cloud amounts peak during January and February and reach a minimum during July and August, high clouds occur more frequently than other types of clouds with a peak in summer. The average annual downwelling surface SW fluxes for total and low clouds (151 and 138 Wm(exp-2), respectively) are less than those under middle and high clouds (188 and 201 Wm(exp -2), respectively), but the downwelling LW fluxes (349 and 356 Wm(exp -2)) underneath total and low clouds are greater than those from middle and high clouds (337 and 333 Wm(exp -2)). Low clouds produce the largest LW warming (55 Wm(exp -2) and SW cooling (-91 Wm(exp -2)) effects with maximum and minimum absolute values in spring and summer, respectively. High clouds have the smallest LW warming (17 Wm(exp -2)) and SW cooling (-37 Wm(exp -2)) effects at the surface. All-sky SW CRF decreases and LW CRF increases with increasing cloud fraction with mean slopes of -0.984 and 0.616 Wm(exp -2)%(exp -1), respectively. Over the entire diurnal cycle, clouds deplete the amount of surface insolation more than they add to the downwelling LW flux. The calculated CRFs do not appear to be significantly

    Full Text Available A substantial amount of research has been conducted into the mental health of the UK military in recent years. This article summarises the results of the various studies and offers possible explanations for differences in findings between the UK and other allied nations. Post-traumatic stress disorder (PTSD rates are perhaps surprisingly low amongst British forces, with prevalence rates of around 4% in personnel who have deployed, rising to 6% in combat troops, despite the high tempo of operations in recent years. The rates in personnel currently on operations are consistently lower than these. Explanations for the lower PTSD prevalence in British troops include variations in combat exposures, demographic differences, higher leader to enlisted soldier ratios, shorter operational tour lengths and differences in access to long-term health care between countries. Delayed-onset PTSD was recently found to be more common than previously supposed, accounting for nearly half of all PTSD cases; however, many of these had sub-syndromal PTSD predating the onset of the full disorder. Rates of common mental health disorders in UK troops are similar or higher to those of the general population, and overall operational deployments are not associated with an increase in mental health problems in UK regular forces. However, there does appear to be a correlation between both deployment and increased alcohol misuse and post-deployment violence in combat troops. Unlike for regular forces, there is an overall association between deployment and mental health problems in Reservists. There have been growing concerns regarding mild traumatic brain injury, though this appears to be low in British troops with an overall prevalence of 4.4% in comparison with 15% in the US military. The current strategies for detection and treatment of mental health problems in British forces are also described. The stance of the UK military is that psychological welfare of troops is

    Data collected at the Department of Energy Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) central facility are analyzed for determining the variability of cloud fraction and radiative forcing at several temporal scales between January 1997 and December 2002. Cloud fractions are estimated for total cloud cover and for single-layer low (0-3 km), middle (3-6 km), and high clouds (greater than 6 km) using ARM SGP ground-based paired lidar-radar measurements. Shortwave (SW), longwave (LW), and net cloud radiative forcings (CRF) are derived from up- and down-looking standard precision spectral pyranometers and precision infrared radiometer measurements. The annual averages of total, and single-layer, nonoverlapped low, middle and high cloud fractions are 0.49, 0.11, 0.03, and 0.17, respectively. Total and low cloud amounts were greatest from December through March and least during July and August. The monthly variation of high cloud amount is relatively small with a broad maximum from May to August. During winter, total cloud cover varies diurnally with a small amplitude, mid-morning maximum and early evening minimum, and during summer it changes by more than 0.14 over the daily cycle with a pronounced early evening minimum. The diurnal variations of mean single-layer cloud cover change with season and cloud height. Annual averages of all-sky, total, and single-layer high, middle, and low LW CRFs are 21.4, 40.2, 16.7, 27.2, and 55.0 Wm(sup -2), respectively; and their SW CRFs are -41.5, -77.2, -37.0, -47.0, and -90.5 Wm(sup -2). Their net CRFs range from -20 to -37 Wm(sup -2). For all-sky, total, and low clouds, the maximum negative net CRFs of -40.1, -70, and -69.5 Wm(sup -2), occur during April; while the respective minimum values of -3.9, -5.7, and -4.6 Wm(sup -2), are found during December. July is the month having maximum negative net CRF of -46.2 Wm(sup -2) for middle clouds, and May has the maximum value of -45.9 Wm(sup -2) for high clouds. An

    Full Text Available Background/Aim. Millions of soldiers around the world represent one of the most vulnerable populations regarding exposure to human immunodeficiency virus (HIV infection. The programs for HIV prevention remain the most viable approach to reducing the spread of HIV infection. Very few studies have tested the effectiveness of HIV preventive interventions undertaken in military population. The aim of this study was to determine the effectiveness of educational film to transfer knowledge about HIV infection to soldiers. Methods. We performed a quasi-experimental study among 102 soldiers of the Serbian Armed Forces. The experimental intervention consisted of the HIV knowledge pre-questionnaire, watching a film on HIV knowledge, then the post-HIV knowledge questionnaire. The results of pre-and post-HIV knowledge questionnaires were compared. Results. There were 23 questions in the test. The average total score on the questionnaire before watching the film was 18.23 and after watching it was 20.14, which was statistically significant difference (p < 0.001. Conclusions. The results of the study show that viewing a film on HIV infection is an effective method of transferring knowledge about HIV to the Serbian military population.

    Armed Forces personnel who deploy as individual augmentees (IAs), with a unit other than their formed unit, often fill shortages or provide specialized knowledge or skill sets. This article examined the effect of deploying as an IA on mental health outcomes and unit cohesion. A U.K. military cohort study was used to compare IAs (n = 1352) with personnel who had deployed with a formed unit (n = 2980). Differences between the groups in questionnaire assessed symptoms of post-traumatic stress disorder (PTSD Checklist-Civilian Version), common mental disorders (General Health Questionnaire-12) and alcohol misuse (Alcohol Use Disorders Identification Test) were examined with logistic and negative-binomial regression analyses. There was no difference between IAs and those who deployed with a formed unit in level of unit cohesion, symptoms of post-traumatic stress disorder or common mental disorder. Deployment as an IA was associated with less alcohol misuse (Odds Ratio 0.77, 95% Confidence Interval 0.63-0.94). IAs appeared able to integrate with the group they deployed with as levels of unit cohesion were similar to personnel who deployed with a formed unit. IAs were also at a lower risk of alcohol misuse compared to personnel who deployed with a formed unit.

  6. Strategic Renewal in Regulatory Environments. How inter- and intra-organisational institutional forces influence European incumbent energy firms

    International Nuclear Information System (INIS)

    How do incumbent firms strategically renew in regulatory environments? Assuming that regulation can both constrain and enable a firm's strategic renewal opportunities, we investigate how and to what extent incumbent firms undertake exploitative and explorative strategic renewal actions in order to remain competitive. Exploitative strategic renewal involves those actions that strengthen or optimise a firm's current resource deployments, whereas explorative strategic renewal relates to actions that generate new sources of value creation for the firm. Based on old institutional theory, new institutional theory, neo-institutional theory and institutional entrepreneurship literature, a multi-level framework that combines selection and adaptation arguments has been developed and applied to investigate strategic renewal behaviour of a sample of European energy incumbents. At industry level of analysis, results show how inter-organisational institutional forces significantly impact firms' choices of exploitative and explorative strategic renewal actions through regulative, normative and cognitive forces. At organisational unit level of analysis, we find that the extent of intra-organisational regulative forces is positively related to exploitative strategic renewal actions. In addition, entrepreneurial proclivity appears to be a catalyst of both exploitative and explorative strategic renewal actions. Finally, our results provide insights how environmental selection and firm level adaptation are interrelated in the context of regulation. The extent of inter-organisational regulative forces positively moderates the relationship between intra-organisational regulative forces and exploitative strategic renewal actions.

Based on old institutional theory, new institutional theory, neo-institutional theory and institutional entrepreneurship literature, a multi-level framework that combines selection and adaptation arguments has been developed and applied to investigate strategic renewal behaviour of a sample of European energy incumbents. At industry level of analysis, results show how inter-organisational institutional forces significantly impact firms' choices of exploitative and explorative strategic renewal actions through regulative, normative and cognitive forces. At organisational unit level of analysis, we find that the extent of intra-organisational regulative forces is positively related to exploitative strategic renewal actions. In addition, entrepreneurial proclivity appears to be a catalyst of both exploitative and explorative strategic renewal actions. Finally, our results provide insights how environmental selection and firm level adaptation are interrelated in the context of regulation. The extent of inter-organisational regulative forces positively moderates the relationship between intra-organisational regulative forces and exploitative strategic renewal actions.

  8. The arms race control

    International Nuclear Information System (INIS)

    Written in 1961, this paper presents the content of a book entitled 'The arms race control' where the author outlined the difference between disarmament and arms control, described the economic and moral role of arms race, the importance of force balance for international security. He wandered whether arms control could ensure this balance and whether nuclear balance meant force balance. Force balance then appears to be a precarious and unsteady component of international security. He commented the challenges of disarmament, recalled some arguments for a nuclear disarmament. Then he discussed what would be an arms control with or without disarmament (either nuclear or conventional)

    Full Text Available A prospective study of all native kidney biopsies performed over one year at the Riyadh Armed Forces Hospital, Riyadh, Saudi Arabia was conducted. During this period, 52 kidney biopsies were performed of which, 49 had adequate tissue. All biopsies were processed for light microscopy, immunofluorescence and electron microscopy. The indications for biopsy included the nephrotic syndrome (n=28; 53.8%, asymptomatic proteinuria (n=12; 21.2%, acute nephritic presentation (n=7; 13.5% and asymptomatic hematuria (n=7; 13.5%. Primary glomerulonephritis (GN, excluding IgA nephropathy (IgAN was seen in 34 of the 49 patients (77.6%. Focal and segmental glomerulosclerosis and mesangial proliferative GN were the most common histological diagnoses (31% and 20.4% respectively. Surprisingly, we found a high prevalence of IgA nephropathy (IgAN of 14.5% in comparison with other studies. The prevalence of mesangiocapillary glomerulonephritis (MCGN was low (2% and can only be explained as incidental. The study patients were followed-up for an average of 26.3 weeks. At the end of the observation period, 50% has unchanged course, 37.5% had improved their renal function and protein excretion, and 12.5% had deteriorated. The prognosis of different GN groups and renal survival rate cannot be assessed or calculated in this study because of the relatively short duration of follow-up. Our study further emphasizes the need for a national GN registry and long-term follow-up, in order to recognize the common patterns of GN, their natural histories, the appropriate line of management, and to try and arrest their progression to end-stage renal disease.

    Full Text Available The aim of the study is the identification and forensic-medical and anthropological evaluation of the remains of soldiers of the National Armed Forces murdered by the secret police in September 1946 in the Opole region. The remains were located during the search for mass graves of victims of the Communist regime carried out by the Institute of National Remembrance (IPN. Material and methods: In June 2012 and April 2013, in the area of the Hubertus clearing between the villages of Barut and Dąbrówka, 41 human bone fragments were revealed in the course of archaeological works carried with use of the open pit method at the probable site of the liquidation of one of the groups of soldiers from the unit of Captain Henryk Flame, aka “Bartek”. In the vicinity of the ruins of the former Scharfenberg manor, in a forest of the Łambinowice commune, a mass grave was discovered containing the remains of at least 25 individuals, mostly young men. The grave was damaged and bore traces of subsequent interference. The forensic-medical-anthropological examination procedures were carried out, the biological profile of the victims evaluated, the minimum number of individuals (MNI determined and the injuries interpreted. Results : A portion of the remains discovered near the village of Barut bore traces of trauma associated with a great force. On the remains from the mass grave in the Łambinowice commune, numerous traces of injuries of the perimortem trauma nature were disclosed, including gunshot damage, both within the skulls and in post-cranial skeletons. Conclusions : The activity of the Institute of National Remembrance led to the confirmation of archival data regarding the site of liquidation of one of the partisan groups of the National Armed Forces in the vicinity of the village of Barut in the Opole region. The research did not allow unambiguous determination of the origin of remains discovered in the mass grave in the Łambinowice commune. The

    Full Text Available The public consciousness is an important characteristic which requires serious enhancement in Thailand. The objective of this study is to examine the existing problems and the public consciousness of the inservice military officers. As a result shows, there is currently no precise training system for public consciousness training at the Royal Thai Armed Forces Headquarters. The tasks are carried out by the chain of command. A study of the existing problems and the public consciousness could lead to the development of a training model to enhance public consciousness. If the in-service military officers, who would return to their hometown all over the country after being discharged, were to have public consciousness characteristics as a foundation for everyday life, the nation would head up the force to help society.

    Full Text Available Adequate nutrition is very essential, especially for the Armed Forces, to buildup their nutritional reserveswhile deriving maximum benefits of training/peak performances in operational situations by keeping theirmorale high. The present study reviews/examines the adequacy of the existing ration scales of the ArmedForces personnel stationed under different terrain conditions of the country/recruits at various training centres.Food samples were collected from different strategic locations during different seasons of the year and analysedfor their nutrient composition like proximal constituents, vitamins A, E, B1, B2, C, and dietary fibre. Basedon the data generated, the daily nutrients/energy consumption by the soldiers/recruits, were calculated separatelyboth for personnel in plains and at high altitudes. Soldiers in plains, on an average consumed protein 124.2+ 13.0 g, fat 98.8 + 29.6 g and energy 3632+317 kcal/person/day, while their counterparts at high altitudesconsumed protein 120.4 + 11.2 g, fat 120.1 + 31.1 g, and energy 3906 + 423 kcal/person/day. The study clearlyindicate that the present ration scales for the Service personnel, both in plains and at high altitudes (9000 ftto 15000 ft is adequate wrt their nutrient density. It is however suggested to ensure adequate supply of goodquality fresh vegetables, fruits, and meat, which inturn would not only help to keep the morale of the soldiers,high and cheerful, especially at high altitudes, but will also enable adequate micronutrient availability. Thefibre levels in the diets of these soldiers have also been found to be well within the limits (20 -35 g/ person/day recommended for optimal health.Defence Science Journal, 2008, 58(6, pp.734-744, DOI:http://dx.doi.org/10.14429/dsj.58.1701

    2014-06-01

    Full Text Available Freedom of expression is one of the most fundamental rights in a democratic society. In fact, the freedom to express one’s opinion and to impart, as well as to receive, information, is essential for the participation in the democratic process. The ability to make decisions as a citizen requires access to information; the participation in the life of the society requires the ability to express one’s opinions. It is imperative that in a democratic society, as it is envisaged by the European Convention on Human Rights (ECHR, everybody is able to express their views, regardless as to whether these views correspond to the views of those who are in power. This ability is one of the key differences between democracy anddictatorship. In particular in the nation-states of Eastern Europe, which have only known freedom for a bit less than a quarter of a century, the growth of democratic structures is inextricably linked to the ability to exercise this right. But while human rights in principle pit the citizen against the State, the citizen who serves the State in a professional function might also wish to express opinions that go against the view of those who are entrusted with leading the State. This is particularly the case when it comes to members of the armed forces. The jurisprudence of the Convention organs with regard to the right of public officials and other State agents to express their opinion freely is not as coherent as it is with regard to other questions concerning the ECHR. In a case decided in late 2013, the European Court of Human Rights dealt with this question with regard to Lithuania. In this article, the authors look at the question of how far the State can restrict the freedom of expression of members of the armed forces under the European Convention on Human Rights.

    The French joint military health corps has long experience in malaria control. Many military physicians played an essential role in the 19th century: Maillot revolutionized malaria treatment by using quinine during the conquest of Algeria, and Laveran discovered the causal parasite (the genus Plasmodium) there. This experience continued under the direction of Laveran and the Sergent brothers on the eastern front in Greek Macedonia during World War I. The vast coordinated control plan established on this front from 1917 delivered the French infantrymen from malaria and led to victory over the Bulgarian forces, which capitulated in September 1918.

    2016-01-01

    Objective: The purpose of this study was to estimate the contribution of the mission in Afghanistan to the burden of mental health problems in the Canadian Armed Forces (CAF). Methods: Data were obtained from the 2013 Canadian Forces Mental Health Survey, which assessed mental disorders using the World Health Organization’s Composite International Diagnostic Interview. The sample consisted of 6696 Regular Force (RegF) personnel, 3384 of whom had deployed in support of the mission. We estimated the association of past-year mental health problems with Afghanistan deployment status, adjusting for covariates using logistic regression; population attributable fractions (PAFs) were also calculated. Results: Indication of a past-year mental disorder was identified in 18.4% (95% confidence interval [CI], 17.0% to 19.7%) of Afghanistan deployers compared with 14.6% (95% CI, 13.3% to 15.8%) in others. Afghanistan-related deployments contributed to the burden of a past-year disorder (PAF = 8.7%; 95% CI, 3.0% to 14.2%), with the highest PAFs being seen for panic disorder (34.7%) and posttraumatic stress disorder (32.1%). The PAFs for individual alcohol use disorders and suicide ideation were not different from zero. Child abuse, however, had a much greater PAF for any past-year disorder (28.7%; 95% CI, 23.4% to 33.7%) than did the Afghanistan mission. Conclusions: The mission in Afghanistan contributed significantly to the burden of mental disorders in the CAF RegF in 2013. However, the much stronger contribution of child abuse highlights the need for strong military mental health systems, even in peacetime, and the need to target the full range of determinants of mental health in prevention and control efforts.

  16. Forces that direct the competition in the electric power industry in the new institutional scenery

    International Nuclear Information System (INIS)

    This work identifies the probable strategic characteristics of the interconnected North-Northeast Brazilian electricity industry, after the current restructuring and privatization process has been implemented. It is a 15.0 thousand MW generation industry supplying more than 33.5 million consumers. The normative scenery for analysis of the electricity industry takes into consideration the premises that the government establishes the vertical separation of generation, transmission, distribution and retailing, and introduces the regulation to a competitive industrial structure in generation and retailing. It is assumed that free access to transmit and distribute electricity and broad choices for consumers are the main features for competition in both generation and retailing. The essence of formulating strategy is to relate a company with its environment, considering the industrial structure. Porter's five forces model for industry environment and competition, emphasizing the role of the government in such regulated industry, is the basic theoretical reference. The main strategic characteristics related to entry barriers, rivalry intensity, supplier power, customer power and substitute products are analyzed. (author)

  17. Incidence of hiatal hernia in service members, active component, U.S. Armed Forces, 2005-2014.

    2016-08-01

    From 2005 through 2014, a total of 27,276 active component service members had incident diagnoses of hiatal hernia documented in their medical records. The overall incidence rate was 19.7 cases per 10,000 person-years (p-yrs); annual incidence rates ranged from 16.5 to 22.2 cases per 10,000 p-yrs. Rates overall increased monotonically with increasing age and were higher among Air Force and Army members, officers, and healthcare workers than their respective counterparts. During the surveillance period, the 27,276 service members who had incident diagnoses of hiatal hernia accounted for 44,092 hiatal hernia-related encounters overall (1.6 encounters per case). Among all incident cases, 235 (0.86%) had surgical repairs documented during the period. The frequency of surgical treatment of hiatal hernias among military members mirrored the low frequency in U.S. civilian practice. During 2010-2014, most surgical procedures (79%) were accomplished via laparoscopic approaches. The incidence rates of hiatal hernia diagnoses reported here likely greatly underestimate the true incidence in U.S. military populations. Reasons for the underestimates and comparisons with other populations are discussed.

    The basic directions of system of antituberculous actions in the Armed Forces of the Russian Federation includes: 1) non-admission of citizens, sick of tuberculosis, on military service; 2) allocation of group of persons with the raised risk of tuberculosis among all military servicemen, dispensary dynamic supervision over them and carrying out of chemoprophylaxis; 3) revealing of tuberculosis among military servicemen at preventive medical inspections (including fluorography), and also in case of reference for medical aid with the symptoms specifying on possibility of tuberculosis; 4) carrying out antiepidemic actions in military unit, in case of revealing patient, sick of tuberculosis, well-timed, qualitatively and in full. The major stage of antituberculous actions is a profound medical examination of young reinforcement (recruits under service call and under the contract) after the arrival in army. Preventive actions in group of persons with the raised risk of tuberculosis also are a priority for the medical service of military unit. Final desinfection, controllable emergency chemoprophylaxis and extraordinary fluorography of contact persons under epidemic indications are crucial important for decrease of morbidity in the army focuses of tuberculosis.

    Full Text Available Background/Aim. Wars of the nineties in former Yugoslavia, Somalia, Rwanda imposed new tasks to the United Nations (UN forces, such as providing humanitarian aid, protection of civilians, peacekeeping, and in many instances providing armed enforcement of peace. The aim of this study was an observational analysis of Serbian participation in the UNs Mission in the Democratic Republic of Congo with the emphasis on stress and coping techniques. Methods. Serbian contribution in this mission dates back to April 2003 till the present days with a military contingent consisting of six members as a part of Air Medical Evacuation Team. The observed stressogenous factors acted before arrival to the mission area and in the mission area. In this paper we analysed ways to overcome them. Results. The productive ways of overwhelming stress used in this mission were: honesty and openness in interpersonal communications, dedication to work, maintaining discipline and order, strict following of appropriate regime of work, diet, rest and recreation; regular communication with family and organizing and participation in various social, cultural and sports manifestations. Conclusion. This analysis indicates that out of all the observed factors, the most important is appropriate selection of personnel.

    Objective To assess whether the delay to care among Canadian Armed Forces (CAF) personnel who sought care for a mental disorder changed over time and in association with CAF mental health system augmentations. Design A stratified, random sample (n=2014) was selected for study from an Afghanistan-deployed cohort (N=30 513) and the 415 (weighted N=4108) individuals diagnosed with an Afghanistan service-related mental disorder were further assessed. Diagnosis-related data were abstracted from medical records (22 June 2010 to 30 May 2011). Other data were extracted from administrative databases. Delay to care was assessed across five mental health system eras: 2002/2004, 2005/2006, 2007, 2008 and 2009/2010. Weighted Cox proportional hazards regression assessed the association between era, handled as a time-dependent covariate, and the outcome while controlling for a broad range of potential confounders (ie, sociodemographic, military and clinical characteristics). Taylor series linearisation methods and sample design weights were applied in generating descriptive and regression analysis statistics. Primary outcome The outcome was the delay to mental healthcare, defined as the latency from most recent Afghanistan deployment return date to diagnosis date, among individuals with an Afghanistan service-related mental disorder diagnosis. Results Mean delay to care was 551 days (95% CI 501 to 602); the median was 400 days. Delay to care decreased in subsequent eras relative to 2002/2004; however, only the most recent era (2009/2010) was statistically significant (adjusted HR (aHR): 3.01 (95% CI 1.91 to 4.73)). Men, operations support occupations, higher ranks, non-musculoskeletal comorbidities and fewer years of military service were also independently associated with longer delays to care. Conclusions CAF mental health system changes were associated with reduced delays to mental healthcare. Further evaluation research is needed to identify the key system changes that

    Cardiomyopathies are a group of heterogeneous myocardial diseases that are frequently inherited and are a recognised cause of premature sudden cardiac death in young individuals. Incomplete expressions of disease and the overlap with the physiological cardiac manifestations of regular intensive exercise create diagnostic challenges in young athletes and military recruits. Early identification is important because sudden death in the absence of prodromal symptoms is a common presentation, and there are several therapeutic strategies to minimise this risk. This paper examines the classification and clinical features of cardiomyopathies with specific reference to a military population and provides a detailed account of the optimum strategy for diagnosis, indications for specialist referral and specific guidance on the occupational significance of cardiomyopathy. A 27-year-old Lance Corporal Signaller presents to his Regimental medical officer (RMO) after feeling 'light-headed' following an 8 mile unloaded run. While waiting to see the RMO, the medical sergeant records a 12-lead ECG. The ECG is reviewed by the RMO immediately prior to the consultation and shows voltage criteria for left ventricular (LV) hypertrophy and inverted T-waves in II, III, aVF and V1-V3 (Figure 1). This Lance Corporal is a unit physical training instructor and engages in >10 h of aerobic exercise per week. He is a non-smoker and does not have any significant medical history. PMID:26246349

    2015-01-01

    The concept of 'deformable arm scale' (completely different from a traditional rigid arm balance) is theoretically introduced and experimentally validated. The idea is not intuitive, but is the result of nonlinear equilibrium kinematics of rods inducing configurational forces, so that deflection of the arms becomes necessary for the equilibrium, which would be impossible for a rigid system. In particular, the rigid arms of usual scales are replaced by a flexible elastic lamina, free of sliding in a frictionless and inclined sliding sleeve, which can reach a unique equilibrium configuration when two vertical dead loads are applied. Prototypes realized to demonstrate the feasibility of the system show a high accuracy in the measure of load within a certain range of use. It is finally shown that the presented results are strongly related to snaking of confined beams, with implications on locomotion of serpents, plumbing, and smart oil drilling.

    Full Text Available Background: Military deployment to combat zones puts military personnel to a number of physical and mental challenges that may adversely affect mental health. Until now, few studies have been performed in Europe on mental health utilization after military deployment. Objective: We compared the incidence of mental health consultations with the Military Mental Health Service (MMHS of military deployed to Afghanistan to that of non-deployed military personnel. Method: We assessed utilization of the MMHS by the full cohort of the Netherlands Armed Forces enlisted between 2008 and 2010 through linkage of mental health and human resource information systems. Results: The total population consisted of 50,508 military (18,233 deployed, 32,275 non-deployed, who accounted for 1,906 new consultations with the MMHS. The follow-up was limited to the first 2 years following deployment. We observed higher mental health care utilization in deployed vs. non-deployed military personnel; hazard ratio (HR, adjusted for sex, military branch and time in service, 1.84 [95% CI 1.61–2.11] in the first and 1.28 [1.09–1.49] in the second year after deployment.

    This image highlights the hidden spiral arms (blue) that were discovered around the nearby galaxy NGC 4625 by the ultraviolet eyes of NASA's Galaxy Evolution Explorer. The image is composed of ultraviolet and visible-light data, from the Galaxy Evolution Explorer and the California Institute of Technology's Digitized Sky Survey, respectively. Near-ultraviolet light is colored green; far-ultraviolet light is colored blue; and optical light is colored red. As the image demonstrates, the lengthy spiral arms are nearly invisible when viewed in optical light while bright in ultraviolet. This is because they are bustling with hot, newborn stars that radiate primarily ultraviolet light. The youthful arms are also very long, stretching out to a distance four times the size of the galaxy's core. They are part of the largest ultraviolet galactic disk discovered so far. Located 31 million light-years away in the constellation Canes Venatici, NGC 4625 is the closest galaxy ever seen with such a young halo of arms. It is slightly smaller than our Milky Way, both in size and mass. However, the fact that this galaxy's disk is forming stars very actively suggests that it might evolve into a more massive and mature galaxy resembling our own. The armless companion galaxy seen below NGC 4625 is called NGC 4618. Astronomers do not know why it lacks arms but speculate that it may have triggered the development of arms in NGC 4625.

  17. Bistable Head Positioning Arm Latch

    Wasson, Ken; Endo, Juro; Mita, Masahiro; Abelein, Nathan

    A simple, low cost, yet effective device has been developed for immobilizing the head-arm assembly in a disk drive or similar mechanism during power-off conditions. The latching scheme also provides a consistent means of releasing the head-arm assembly from the immobilized position upon power up of the disk drive. The latch uses no electrical power in either immobilized or released state. This design is immune to extreme torque and linear shock forces applied to the disk drive case. The latch system can use the energy stored in the spinning disks to drive the head-arm assembly toward a safe position while simultaneously arming the latch mechanism to secure the head-arm assembly in the safe position upon arrival. A low energy five msec pulse of current drives the latch from one state to the other. Solenoids as presently used in latch mechanisms are bulky, expensive, have variable force characteristics, and often generate contaminants. The latch described in this paper is expected to replace such solenoids. It may also replace small magnet latches, which have limited latch force and apply unwanted torque to a proximate head positioning arm.

  19. Response of the middle atmosphere to anthropogenic and natural forcings in the CMIP5 simulations with the Max Planck Institute Earth system model

    KAUST Repository

    Schmidt, H.

    2013-03-06

    The ECHAM6 atmospheric general circulation model is the atmosphere component of the Max Planck Institute Earth System Model (MPI-ESM) that is used in the Coupled Model Intercomparison Project Phase 5 (CMIP5) simulations. As ECHAM6 has its uppermost layer centered at 0.01 hPa in the upper mesosphere, these simulations offer the opportunity to study the middle atmosphere climate change and its relation to the troposphere on the basis of a very comprehensive set of state-of-the-art model simulations. The goals of this paper are (a) to introduce those new features of ECHAM6 particularly relevant for the middle atmosphere, including external forcing data, and (b) to evaluate the simulated middle atmosphere and describe the simulated response to natural and anthropogenic forcings. New features in ECHAM6 with respect to ECHAM5 include a new short-wave radiation scheme, the option to vary spectral irradiance independent of total solar irradiance, and a latitude-dependent gravity-wave source strength. The description of external forcing data focuses on solar irradiance and ozone. Stratospheric temperature trends simulated with the MPI-ESM for the last decades of the 20th century agree well with observations. The future projections depend strongly on the scenario. Under the high emission scenario RCP8.5, simulated temperatures are locally lower by more than 20 K than preindustrial values. Many of the simulated patterns of the responses to natural forcings as provided by solar variability, volcanic aerosols, and El Nino-Southern Oscillation, largely agree with the observations. 2013.

    2013-01-01

    Skeletal structures act as lever arms during walking. Muscle activity and the ground reaction against gravity exert forces on the skeleton, which generate torque (moments) around joints. These lead to the sequence of movements which form normal human gait. Skeletal deformities in cerebral palsy (CP) affect the function of bones as lever arms and compromise gait. Lever arm dysfunction should be carefully considered when contemplating treatment to improve gait in children with CP.

    Embedding computational models in the physical world is a critical step towards constraining their behavior and building practical applications. Here we aim to drive a realistic musculoskeletal arm model using a biomimetic cortical spiking model, and make a robot arm reproduce the same trajectories in real time. Our cortical model consisted of a 3-layered cortex, composed of several hundred spiking model-neurons, which display physiologically realistic dynamics. We interconnected the cortical model to a two-joint musculoskeletal model of a human arm, with realistic anatomical and biomechanical properties. The virtual arm received muscle excitations from the neuronal model, and fed back proprioceptive information, forming a closed-loop system. The cortical model was trained using spike timing-dependent reinforcement learning to drive the virtual arm in a 2D reaching task. Limb position was used to simultaneously control a robot arm using an improved network interface. Virtual arm muscle activations responded to motoneuron firing rates, with virtual arm muscles lengths encoded via population coding in the proprioceptive population. After training, the virtual arm performed reaching movements which were smoother and more realistic than those obtained using a simplistic arm model. This system provided access to both spiking network properties and to arm biophysical properties, including muscle forces. The use of a musculoskeletal virtual arm and the improved control system allowed the robot arm to perform movements which were smoother than those reported in our previous paper using a simplistic arm. This work provides a novel approach consisting of bidirectionally connecting a cortical model to a realistic virtual arm, and using the system output to drive a robotic arm in real time. Our techniques are applicable to the future development of brain neuroprosthetic control systems, and may enable enhanced brain-machine interfaces with the possibility for finer control of

    1986-03-01

    Most of the nuclear debate consists of arguments about which weapons systems should be built, controlled, canceled, frozen, or retired. Short of virtually complete, multilateral nuclear disarmament, however, no change in the pace, balance, or even the direction of the arms race can make much difference in the risk of nuclear war, the damage should one occur, or the division of international political power. This includes Star Wars, the nuclear freeze, and even large cuts in or stabilization of offensive nuclear arsenals. A better starting point for nuclear politics would be the insight that nuclear weapons have completely changed the logic of power as it has been handed down through the ages. Military force, perfected to its highest level, has invalidated itself - for in a nuclearized world, any resort to force by a nuclear power risks escalation to its ultimate level, and thus to oblivion for all. Trying to rationalize and control the ultimate force is far less realistic and important than limiting the provocation of conflict and the use of force at lower, non-nuclear levels - by the United States, it clients, and, to the extent possible, its adversaries. 13 references.

At present the importance of the health non-commissioned officers (NCO) is emphacized.In practice, the nealth NCO are the right-hand men of the military doctors. However, most of the heath NCOs have only the educational levels of senior even junior middle schools,haven' t received School record education, and lack of information technology knowledge and skills and Intrinsic motivation. Not willing to remain in the army and do long-term service, some of them apply forretirement.To solve these problems,the performance assessment system should be implemented and management should be strengthened. Professional trining should be enforced so as to raise the professional quality of the NCOs,for example, in syomatological, laboratory examionation, radology, etc. Attention should be paid to military-civilian interface sp as to ensure the employment of the health NCOs out of service.

    2012-01-01

    In order to understand the physical mechanisms underlying non-steady stellar spiral arms in disk galaxies, we analyzed the growing and damping phases of their spiral arms using three-dimensional $N$-body simulations. We confirmed that the spiral arms are formed due to a swing amplification mechanism that reinforces density enhancement as a seeded wake. In the damping phase, the Coriolis force exerted on a portion of the arm surpasses the gravitational force that acts to shrink the portion. Consequently, the stars in the portion escape from the arm, and subsequently they form a new arm at a different location. The time-dependent nature of the spiral arms are originated in the continual repetition of this non-linear phenomenon. Since a spiral arm does not rigidly rotate, but follows the galactic differential rotation, the stars in the arm rotate at almost the same rate as the arm. In other words, every single position in the arm can be regarded as the co-rotation point. Due to interaction with their host arms, ...

Consequently, the stars in the portion escape from the arm, and subsequently they form a new arm at a different location.

Since a spiral arm does not rigidly rotate, but follows the galactic differential rotation, the stars in the arm rotate at almost the same rate as the arm. In other words, every single position in the arm can be regarded as the corotation point. Due to interaction with their host arms, the energy and angular momentum of the stars change, thereby causing radial migration of the stars. During this process, the kinetic energy of random motion (random energy) of the stars does not significantly increase, and the disk remains dynamically cold. Owing to this low degree of disk heating, short-lived spiral arms can recurrently develop over many rotational periods. The resultant structure of the spiral arms in the N-body simulations is consistent with the observational nature of spiral galaxies. We conclude that the formation and structure of spiral arms in isolated disk galaxies can be reasonably understood by nonlinear interactions between a spiral arm and its constituent stars.

    Energy Technology Data Exchange (ETDEWEB)

    Woolsey, R.J. (ed.)

    1984-01-01

    The range of debate over strategy and arms control today is broader than it was in the late 1950s and early 1960s. In part this is because the early 1980s debate has involved questioning of the fundamental notion of deterrence - by no less than the American Catholic bishops. Today's debate has also seen a national nuclear freeze campaign that, although its congressional supporters have held firmly to a bilateral approach, was tilted perceptibly towards unilateralism by noncongressional leaders at their national conference in February 1983. In one way or another the authors wrestle with different aspects of one central question: could the beginning steps for any consensus be possible, in today's climate, on strategic issues. Ethical issues are addressed in the first 3 papers: Charles Krauthammer, On Nuclear Morality; Patrick Glynn, The Moral Case for the Arms Buildup; and Michael Quinlarc, Thinking Deterrence Through. Three chapters on strategic considerations include: Brent Snowcroft, Understanding the US Strategic Arsenal; William J. Perry, Technological Prospects for US Strategic Forces; and Richard Burt, The Strategic and Political Lessons of INF. Arms control and politics is treated in chapters by: Walter B. Slocombe, Arms Control: Prospects; and Colin S. Gray, Arms Control: Problems. The nonnuclear dimensions of strategy are discussed in chapters by Amory B. and L. Hunter Lovins, Reducing Vulnerability - The Energy Jugular; and Robert Kupperman, Vulnerable America. The chapters on space and defense are: Hans Mark, Arms Control and Space Technology; and Newt Gingrich and John Madison, Space and National Defense. The concluding chapters are by Sen. Sam Nunn, The Need to Reshape Military Stategy; and the editor, R. James Woolsey, The Politics of Vulnerability, 1980-1983.

    North Korea proposed the strategy of carrying out economic construction and building nuclear armed forces simultaneously on March 2013.For various factors, economy was more emphasized in this strategy than the similar policy in the past while the national defense was the priority.However, such an economic reform can not re-move the drawbacks of planned economy;therefore, it is limited.Besides, factors such as nuclear weapon develop-ment and investment environment may impede and challenge North Korea’ s economic cause.It is proposed that North Korea should improve its economic efficiency and management, as well as attract more foreign investment and open wider to the outside world.%2013年3月,朝鲜提出金正恩时代的“国家运行基本政策”———“经济与核武并行路线”。其中经济领域的任务,呈现不同以往的特征,对经济的重视较以往已达到了更高的程度,多种因素促使朝鲜把经济当作最重要的任务之一,同样为“并行路线”,金日成时期的“并行路线”重在国防,金正恩则将焦点置于经济。然而,不涉及计划经济本身的弊端的经济改革仍将是有限度的,加之核开发问题、投资环境等一系列制约性因素,未来朝鲜在经济领域所推行的任务仍将面临各种障碍和挑战,其预期的效果也将有待时间的检验。在内部提高效率改善经济管理,同时为从外部引进外资而扩大开放将成为今后一个时期朝鲜的经济政策方向。

  4. Retraining of interjoint arm coordination after stroke using robot-assisted time-independent functional training

    2011-05-01

    Full Text Available We have developed a haptic-based approach for retraining of interjoint coordination following stroke called time-independent functional training (TIFT and implemented this mode in the ARMin III robotic exoskeleton. The ARMin III robot was developed by Drs. Robert Riener and Tobias Nef at the Swiss Federal Institute of Technology Zurich (Eidgenossische Technische Hochschule Zurich, or ETH Zurich, in Zurich, Switzerland. In the TIFT mode, the robot maintains arm movements within the proper kinematic trajectory via haptic walls at each joint. These arm movements focus training of interjoint coordination with highly intuitive real-time feedback of perform-ance; arm movements advance within the trajectory only if their movement coordination is correct. In initial testing, 37 nondisabled subjects received a single session of learning of a complex pattern. Subjects were randomized to TIFT or visual demonstration or moved along with the robot as it moved though the pattern (time-dependent [TD] training. We examined visual demonstration to separate the effects of action observation on motor learning from the effects of the two haptic guidance methods. During these training trials, TIFT subjects reduced error and interaction forces between the robot and arm, while TD subject performance did not change. All groups showed significant learning of the trajectory during unassisted recall trials, but we observed no difference in learning between groups, possibly because this learning task is dominated by vision. Further testing in stroke populations is warranted.

    International Nuclear Information System (INIS)

    Nowadays, the use of various nuclear sources in some fields of the life has brought many practical advantages in general; especially in the next several years, our country will begin construction of the first nuclear plant. However, if there were user carelessness or objective disadvantageous factors (earthquake, tsunami, etc.), that disadvantages could lead to a radiation accident or nuclear accident which causes damages not only for economy but also for public health. Therefore, the emergency response to radiation accident, especially the emergency medical response that has a great important position. To satisfy this real demand, in 1996, Vietnam Ministry of Defence made the decision to establish Center for Nuclear Medicine and Radiation Protecting (now becomes Military Institute of Medical Radiology and Oncology) with the main missions are research, applying radiation protecting methods and organizing treatments to radiation injured victims. To fulfill above main missions, with the help of Vietnam Atomic Energy Institute (VAEI), Vietnam Agency for Radiation and Nuclear Safety (VARANS), the doctors and staffs of our Institute have been participated in the international training courses and workshops that organized in Vietnam or in regional countries about emergency medical response to radiation accidents, they get valuable information, knowledge and documents from these courses and workshops. Depending on the principles of radiation emergency medical response to nuclear/ radiation accidents that International Atomic Energy Agency (IAEA) guided, and with the experience learned from other countries in Asia region, our Institute have been gradually improving on organization and curing processes for the radiation victims and also setting the preparedness for emergency medical response to radiation accidents if maybe they could occur.

    2015-10-01

    The Atmospheric Radiation Measurement (ARM) Program was created in 1989 with funding from the U.S. Department of Energy (DOE) to develop several highly instrumented ground stations to study cloud formation processes and their influence on radiative transfer. In 2003, the ARM Program became a national scientific user facility, known as the ARM Climate Research Facility. This scientific infrastructure provides for fixed sites, mobile facilities, an aerial facility, and a data archive available for use by scientists worldwide through the ARM Climate Research Facility—a scientific user facility. The ARM Climate Research Facility currently operates more than 300 instrument systems that provide ground-based observations of the atmospheric column. To keep ARM at the forefront of climate observations, the ARM infrastructure depends heavily on instrument scientists and engineers, also known as lead mentors. Lead mentors must have an excellent understanding of in situ and remote-sensing instrumentation theory and operation and have comprehensive knowledge of critical scale-dependent atmospheric processes. They must also possess the technical and analytical skills to develop new data retrievals that provide innovative approaches for creating research-quality data sets. The ARM Climate Research Facility is seeking the best overall qualified candidate who can fulfill lead mentor requirements in a timely manner.

  1. Strategic forces briefing

    1989-04-06

    The Strategic Forces Briefing'' is our attempt, accomplished over the past several months, to outline and highlight the more significant strategic force issues that must be addressed in the near future. Some issues are recurrent: the need for an effective modernized Triad and a constant concern for force survivability. Some issues derive from arms control: the Strategic Arms Reduction Talks (SALT) are sufficiently advanced to set broad numerical limits on forces, but not so constraining as to preclude choices among weapon systems and deployment modes. Finally, a new administration faced with serious budgetary problems must strive for the most effective strategic forces limited dollars can buy and support. A review of strategic forces logically begins with consideration of the missions the forces are charged with. We begin the briefing with a short review of targeting policy and implementation within the constraints of available unclassified information. We then review each element of the Triad with sections on SLBMs, ICBMs, and Air-Breathing (bomber and cruise missile) systems. A short section at the end deals with the potential impact of strategic defense on offensive force planning. We consider ABM, ASAT, and air defense; but we do not attempt to address the technical issues of strategic defense per se. The final section gives a brief overview of the tritium supply problem. We conclude with a summary of recommendations that emerge from our review. The results of calculation on the effectiveness of various weapon systems as a function of cost that are presented in the briefing are by Paul Chrzanowski.

    Full Text Available   Nonspecific activity-related arm pain is characterized by an absence of objective physical findings and symptoms that do not correspond with objective pathophysiology. Arm pain without strict diagnosis is often related to activity, work-related activity in particular, and is often seen in patients with physically demanding work. Psychological factors such as catastrophic thinking, symptoms of depression, and heightened illness concern determine a substantial percentage of the disability associated with puzzling hand and arm pains. Ergonomic modifications can help to control symptoms, but optimal health may require collaborative management incorporating psychosocial and psychological elements of illness.

    2006-12-01

    In this study, we investigated biomechanical contributions of the high guard position of the arms observed only in a subgroup of toddlers at very early stages of gait development. Six healthy toddlers who showed this peculiar arm posture were involved in this study. They participated in two data collection sessions (1 month apart). We used three-dimensional analysis of arm posture during gait to estimate the changes in forces and torques generated by the arms and acting on the upper trunk segment. Across visits, toddlers' increase in walking speeds coincided with lowering arm postures. Despite the apparent trend of changes in arm posture in this group of toddlers, the interaction between arm posture and upper trunk position created a variety of changes in forces and torques among individuals. Findings of this study exhibited an example of the exploration of dynamics by toddlers in the early stage of gait development.

    This report first outlines that nuclear installations are subject to illegal intrusions which challenge their safety and security. It outlines that these installations are extremely sensitive and particularly threatened (the energy sector, as a key sector, is submitted to a specific regulation, and threats are potentially serious), that, beyond the terrorist threat and the risk of sabotage, nuclear installations are regularly facing other illegal behaviours (illegal intrusions are a recurrent issue, and drones are emerging as a new kind of threat), that the protection of nuclear installations is carried out by forces dedicated to this mission (a specialised military force for EDF sites, civil forces for the CEA and Areva, the role of the French Air Force to protect airspace), and that recent legal advances must be deepened. The second part outlines that the present legal protection framework in inadequate and incomplete. The French legal regime is presented and some foreign examples are evoked, and the need of creation of a specific penal regime is outlined. The general discussion and the discussion of the bill project articles are reported. A table proposes a comparative overview between the existing arrangement, the bill project text, and the Commission's text

    This report summarizes results of a visit by the report authors to Marinduque Island, Philippines, in May 2000. The purpose of the visit was to conduct a preliminary examination of environmental problems created by a 1996 tailings spill from the Marcopper open-pit copper mine. The mine was operated from 1969-1996 by Macropper Mining Corperation, under 39.9% ownership, and design and management control of Placer Dome, Inc. Our trip expenses to and from the Philippines were funded by the USGS. In-country expenses were paid by the offices of Congressman Reyes and the Governor of Marinduque, Carmencita O. Reyes. This report includes observations we made based on our relatively short visit to the island, and observations based upon a preliminary review of the literature available on the islanda??s mining-environmental issues. In addition, we have included preliminary interpretations and analytical results of some water, sediment, and mine waste samples collected during our trip. We also highlight the environmental and human health issues we fell are in need of further study and consideration for mitigation or remediation. This report is preliminary and is not intended to be a comprehensive or final review of the islanda??s mining-environmental issues; many areas of further study are clearly neededa?|

  10. Documenting the Effects of Armed Conflict on Population Health.

    War and other forms of armed conflict have profound adverse effects on population health. It is important to document these effects to inform the general public and policy makers about the consequences of armed conflict, provide services to meet the needs of affected populations, protect human rights and document violations of international humanitarian law, and help to prevent future armed conflict. Documentation can be accomplished with surveillance, epidemiological surveys, and rapid assessment. Challenges include inadequate or absent data systems, social breakdown, forced migration, reporting biases, and the fog of war. The adverse effects of the Iraq War on population health demonstrate how the effects of armed conflict on population health can be documented. We recommend the establishment of an independent mechanism, operated by the United Nations or a multilateral organization, to investigate and document the effects of armed conflict on population health.

    Armed conflict has raged in Colombia since at least the 1960’s, involving governmental forces, rebel groups, and paramilitary forces. The Uribe government (2002-2010) declared that Colombia was not in a ‘state of armed conflict’ but was rather facing a ‘terrorist threat’. This declaration was done in fear of conferring a political status to the armed groups, and most particularly, in fear that a recognition of armed conflict would open the possibility of endowing the Revolutionary Ar...

  14. Octopus-inspired multi-arm robotic swimming.

    2015-05-13

    The outstanding locomotor and manipulation characteristics of the octopus have recently inspired the development, by our group, of multi-functional robotic swimmers, featuring both manipulation and locomotion capabilities, which could be of significant engineering interest in underwater applications. During its little-studied arm-swimming behavior, as opposed to the better known jetting via the siphon, the animal appears to generate considerable propulsive thrust and rapid acceleration, predominantly employing movements of its arms. In this work, we capture the fundamental characteristics of the corresponding complex pattern of arm motion by a sculling profile, involving a fast power stroke and a slow recovery stroke. We investigate the propulsive capabilities of a multi-arm robotic system under various swimming gaits, namely patterns of arm coordination, which achieve the generation of forward, as well as backward, propulsion and turning. A lumped-element model of the robotic swimmer, which considers arm compliance and the interaction with the aquatic environment, was used to study the characteristics of these gaits, the effect of various kinematic parameters on propulsion, and the generation of complex trajectories. This investigation focuses on relatively high-stiffness arms. Experiments employing a compliant-body robotic prototype swimmer with eight compliant arms, all made of polyurethane, inside a water tank, successfully demonstrated this novel mode of underwater propulsion. Speeds of up to 0.26 body lengths per second (approximately 100 mm s(-1)), and propulsive forces of up to 3.5 N were achieved, with a non-dimensional cost of transport of 1.42 with all eight arms and of 0.9 with only two active arms. The experiments confirmed the computational results and verified the multi-arm maneuverability and simultaneous object grasping capability of such systems.

  15. Phoenix Stretches its Arm

    2008-01-01

    [figure removed for brevity, see original site] Click on image for animation The Phoenix spacecraft is scheduled to begin raising its robotic arm up and out of its stowed configuration on the third Martian day, or Sol 3 (May 28, 2008) of the mission. This artist's animation, based on engineering models, shows how Phoenix will accomplish this task. First, its wrist actuator will rotate, releasing its launch-restraint pin. Next, the forearm moves up, releasing the elbow launch-restraint pin. The elbow will then move up and over in small steps, a process referred to as 'staircasing.' This ensures that the arm's protective biobarrier wrap, now unpeeled and lying to the side of the arm, will not get in the way of the arm's deployment. The arm is scheduled to straighten all the way out on Sol 4 (May 29, 2008), after engineers have reviewed images and telemetry data from the spacecraft showing that the biobarrier material has been cleared. The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.

    2012-02-01

    Full Text Available There are many causes of flywheel failure. Among them, maximum tensile and bending stresses induced in the rim and tensile stresses induced in the arm under the action of centrifugal forces are the main causes of flywheel failure. Hence in this work evaluation of stresses in the rim and arm are studied using finite element method and results are validated by analytical calculations .The models of flywheel having four, six and eight no. arms are developed for FE analysis. The FE analysis is carried out for different cases of loading applied on the flywheel and the maximum Von mises stresses and deflection in the rim are determined. From this analysis it is found that Maximum stresses induced are in the rim and arm junction. Due to tangential forces, maximum bending stresses occurs near the hub end of the arm. It is also observed that for low angular velocity the effect gravity on stresses and deflection of rim and arm is predominant.

  11. Optimized electrostatic inchworm motors using a flexible driving arm

    International Nuclear Information System (INIS)

    A new motor architecture that uses in-plane electrostatic gap-closing actuators along with a flexible driving arm mechanism to improve motor force density is introduced, optimized, manufactured, and tested. This motor operates similarly to other inchworm-based microactuators by accumulating small displacements from the actuators into much larger displacements in the motor. Using an analytical model of the inchworm motor based on the static force equilibrium condition, optimizations of a full motor design were performed to maximize motor force density. In addition, force losses from supporting flexures were included to calculate the theoretical motor efficiency for different motor designs. This force density optimization analysis of the gap-closing actuators and supporting motor structures provided the basis for designing and manufacturing inchworm motors with flexible driving arms and gap-closing actuators. The motor required only a single-mask fabrication and demonstrated robust performance, a maximum speed of 4.8 mm s−1, and a maximum force on the shuttle of 1.88 mN at 110 V which corresponds to area force density of 1.38 mN mm−2. In addition, instead of estimating motor force based on drawn or measured dimensions which often overestimates force, the demonstrated maximum motor force was measured using calibrated springs. The efficiency of the manufactured motor was measured at 8.75% using capacitance measurements and useful work output. (paper)

  12. Can a small-changes approach help address the obesity epidemic? A report of the Joint Task Force of the American Society for Nutrition, Institute of Food Technologists, and International Food Information Council.

    Science.gov (United States)

    Hill, James O

    2009-02-01

    The continued rise in obesity rates in most countries suggests that current programs and initiatives designed to combat obesity have not been successful in reversing the obesity epidemic. Obesity rates are increasing because of a gradual weight gain in most populations. There has been little long-term success in treating established obesity through lifestyle change, perhaps because of the large permanent changes in diet and physical activity required to keep weight off. An alternative strategy to address the obesity epidemic involves not focusing on weight loss but promoting small changes in diet and physical activity to initially prevent further weight gain. With the use of this strategy, obesity rates could first be stabilized in most populations and then, over time, decrease gradually. Supporting data show that small reductions in conscious energy intake and increases in physical activity can reduce excessive weight gain. The opportunity exists to use the small-changes approach to bring different stakeholders together to create a national initiative to address the global epidemic of obesity. The Joint Task Force of the American Society for Nutrition, Institute of Food Technologists, and International Food Information Council believe that a small-changes framework, aimed at helping people make conscious small changes in lifestyle behaviors, in combination with efforts by the private sector to gradually "ratchet down" some of the environmental factors that have contributed to excessive energy intake and the declining rates of physical activity, can be successful in reducing obesity rates. Such an initiative would benefit from the support of educational and social marketing campaigns developed with governmental input and support. PMID:19088151

    探讨本体位置不控、姿态受控的漂浮基柔性臂空间机器人系统在惯性参数不确定情况下的动力学建模与控制问题.根据系统位置几何关系、动量守恒关系和第二类拉格朗日方程,由假设模态法,建立漂浮基柔性臂空间机器人的系统动力学模型.利用该模型,针对系统惯性参数不确定情况,提出具有L2扰动抑制的刚性运动神经网络L2增益鲁棒控制策略,以使柔性臂空间机器人的本体姿态到达期望位置的同时,机械臂各关节铰能够协调地跟踪关节空间的期望轨迹.为了主动抑制柔性振动,运用虚拟力的概念,构造同时反映柔性模态和刚性运动轨迹的混合期望轨迹,通过改造原有的控制方案,提出基于虚拟力概念的神经网络L2增益鲁棒控制策略.提出控制器的优点在于,既不要求系统动力学方程关于惯性参数呈线性函数关系,也无须预知系统精确的动力学模型;由于运用了虚拟力的概念,从而仅通过设计一个控制输入便可同时保证刚性轨迹跟踪并对柔性振动进行主动抑制,更适应于空间机器人系统的实际应用.理论分析及仿真算例均表明了控制方法的可行性.%Concerned dynamic modeling and control problems are discussed for free-floating flexible arm space robot with uncertain parameters and an uncontrolled base. According to the geometric relationship and law of conversation of momentum, the Lagrange equation of the second kind is utilized to model the dynamic function of the flexible arm space robot incorporating the assumed modes method. By using this model, a neural network L-two-gain robust control scheme with i-two-gain disturbance attenuation is proposed to dominate the base attitude and the joint angle of manipulator to track desired trajectories synchronously in joint space on condition that system parameters are unknown. In order to damp out vibration, conception of virtual force is used to design

    In the chapter, I discuss the role day care institutions play in the construction of the idea of proper childhood in Denmark. Drawing on findings from research on ethnic minority children in two Danish day care institutions, I begin with a discussion of how childcare institutions act as civilising...... agents, empowered with the legitimate right to define and control normality and proper ways of behaving oneself. I aim to show how institutions come to define the normal child and proper childhood in accordance with current efforts toward reinventing national culture, exemplified by legislation requiring...... current testing of Danish language fluency levels among pre-school minority children. Testing language skills marks and defines distinctions that reinforce images of deviance that, in turn, legitimize initiatives to enrol children, specifically minority children, in child care institutions....

  2. Elastic lever arm model for myosin V

    CERN Document Server

    Vilfan, A

    2005-01-01

    We present a mechanochemical model for myosin V, a two-headed processive motor protein. We derive the properties of a dimer from those of an individual head, which we model both with a 4-state cycle (detached, attached with ADP.Pi, attached with ADP and attached without nucleotide) and alternatively with a 5-state cycle (where the power stroke is not tightly coupled to the phosphate release). In each state the lever arm leaves the head at a different, but fixed, angle. The lever arm itself is described as an elastic rod. The chemical cycles of both heads are coordinated exclusively by the mechanical connection between the two lever arms. The model explains head coordination by showing that the lead head only binds to actin after the power stroke in the trail head and that it only undergoes its power stroke after the trail head unbinds from actin. Both models (4- and 5-state) reproduce the observed hand-over-hand motion and fit the measured force-velocity relations. The main difference between the two models c...

  4. Study on a 7-DOF anthropomorphic weld arm

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    A kind of new obstacle space expression is proposed in this paper, in which a virtual force field (VFF) is built. Using the torque and joint optimization acted by the virtual force field on the anthropomorphic weld arm, the real-time selection of a redundant join (R-joint) is done and its equivalent virtual torque is obtained, thus the redundant joint can be controlled with whose force feedback. An inverse kinematics solution of a 6-DOF robot is applied to other six joints of the arm. Simulation experiments indicate the new inverse kinematics solution has perfect collision avoidance effect, and it is well simplified. Therefore, it can be applied to a welding task in complex operation space.

The target capture process is considered as pre-impact phase,impact phase and post-impact phase. The space robot and target are separated subsystem in the pre-impact phase, and the dynamics model of free-floating space robot is derived by the second Lagrange equation. In the impact phase, base on the total momentum conservation of space robot and target, the impact effect for the space robot motion is calculated by momentum theorem. In the post-impact phase, the dual-arm space robot has captured the target and formed a closed-chaln hybrid system, considering the unstable motion which is caused by the impact effect in the impact phase, a robust control algorithm is proposed

    Safety of the occupant during the crash is very essential design element. Many researches have been investigated in reducing the fatal injury of occupant. They are focusing on the development of a dummy in order to obtain the real human-like motion. However, they have not considered the arm resist motion during the car accident. In this study, we would like to suggest the importance of the reactive force of the arm in a car crash. The influences of reactive force acting on the human upper extremity were investigated using the impedance experimental method with lumped mass model of hand system and a Hybrid III dummy with human-like arm. Impedance parameters (e.g. inertia, spring constant and damping coefficient) of the elbow joint in maximum activation level were measured by free oscillation test using single axis robot. The results showed that without seat belt, the reactive force of human arm reduced the head, chest, and femur injury, and the flexion moment of the neck is higher than that of the conventional dummy.

    U.S. service members are at risk of malaria when they are assigned to endemic areas (e.g., Korea), participate in operations in endemic areas (e.g., Afghanistan, Africa) and visit malarious areas during personal travel. In 2011, 124 service members were reported with malaria. Nearly three-fourths of cases were presumably acquired in Afghanistan (n=91) and one-fifth were considered acquired in Africa (n=24). One-quarter of cases were caused by P. vivax and one-fifth by P. falciparum (including 6 Afghanistan-acquired infections); most cases were reported as "unspecified" malaria. Malaria was diagnosed/reported from 51 different medical facilities in the United States, Afghanistan, Kyrgyzstan, Iraq, Germany and Korea. Providers of care to military members should be knowledgeable regarding and vigilant for clinical presentations of malaria outside of endemic areas. PMID:22309389

  15. Institutions and Modernity

    Directory of Open Access Journals (Sweden)

    Witold Morawski

    2013-09-01

    Full Text Available Purpose: Modernity consists of many confl icting aspects: It brings many empty promises, yet has resulted in new institutions that create bridges between the values and interests of millions of people who seek freedom, prosperity, quality of life, strengthened democracy and social justice. In this paper I attempt to a gain and loss account against modernity, because institutional rules are not only conducive to cooperative interactions, but to hostile interactions as well. People are not always guided by moral commitment, but rather more often driven by cold calculation or coercion.Methodology: Modernity has at least three defi nitions. The fi rst defi nition is based on ideas that took over the imagination of the era. The second defi nition is based on an analysis of the behavior of people who respond to reason as well as emotion and believe that they act more rationally than their ancestors or the traditional “others”. The third defi nition is the one closest to my heart, consisting of the use of institutional categories. Institutions offer practical ways of connecting ideas and people. The challenge for them is the result of deepening local and national interdependencies, but increasingly often also regional (e.g. European and global. Interdependencies are the result of the scientifi c and technological revolution, global markets, global governance mechanisms, the emergence of new social forces and cultural confl icts (against the background of reconciling identity and differences.Conclusions: The most important task is to identify the mechanisms of complex systems so that people know how to act under conditions of uncertainty, risk and crisis. Hence, the expectations toward institutions often exceed their abilities. Even though new institutions are being created and old ones are being fixed, we are witnessing and participating in, institutional paralysis and the decay (e.g. corruption. In this situation, it is imperative not only to

  16. Strong Force

    CERN Multimedia

    Without the strong force, there could be no life. The carbon in living matter is synthesised in stars via the strong force. Lighter atomic nuclei become bound together in a process called nuclear fusion. A minor change in this interaction would make life impossible. As its name suggests, the strong force is the most powerful of the 4 forces, yet its sphere of influence is limited to within the atomic nucleus. Indeed it is the strong force that holds together the quarks inside the positively charged protons. Without this glue, the quarks would fly apart repulsed by electromagnetism. In fact, it is impossible to separate 2 quarks : so much energy is needed, that a second pair of quarks is produced. Text for the interactive: Can you pull apart the quarks inside a proton?

  18. Segmental and kinetic contributions in vertical jumps performed with and without an arm swing.

    Feltner, Michael E; Bishop, Elijah J; Perez, Cassandra M

    2004-09-01

    To determine the contributions of the motions of the body segments to the vertical ground reaction force (Fz), the joint torques produced by the leg muscles, and the time course of vertical velocity generation during a vertical jump, 15 men were videotaped performing countermovement vertical jumps from a force plate with and without an arm swing. Linear kinematic, Fz, and joint torque data were computed and compared using repeated measures analysis of variance. Maximum jump height was significantly larger in the arm swing jumps compared to the no arm swing jumps and was due to both a higher height of the center of mass (CM) at takeoff (54%) and a larger vertical velocity of the CM at takeoff (46%). The net vertical impulse created during the propulsive phase of the arm swing jumps was greater due to a trend of an increased duration (0.021 s) of the propulsive phase and not to larger average values of Fz. In the arm swing jumps, the arm motion resulted in the arms making a larger maximal contribution to Fz during the middle of the propulsive phase and decreased the negative contribution of the trunk-head and thigh to Fz late in the propulsive phase. Last, the arm swing decreased the extensor torques at the hip (13%), knee (10%), and ankle (10%) early in the propulsive phase but augmented these same extensor torques later in the propulsive phase.

  19. The objective qualification of non-international armed conflicts: A Colombian case study

    Full Text Available

    Armed conflict has raged in Colombia since at least the 1960’s, involving governmental forces, rebel groups, and paramilitary forces. The Uribe government (2002-2010 declared that Colombia was not in a ‘state of armed conflict’ but was rather facing a ‘terrorist threat’. This declaration was done in fear of conferring a political status to the armed groups, and most particularly, in fear that a recognition of armed conflict would open the possibility of endowing the Revolutionary Armed Forces of Colombia (FARC with a ‘belligerency status’. From a legal point of view, the government’s fears were unfounded, since contemporary international humanitarian law does not require a formal for a situation to qualify as armed conflict. During the Uribe administration, efforts were made by the Ministry of Defense to identify operational rules of engagement with precision, violations of international humanitarian law were publicly denounced, and the apex courts adjudicated on issues of international humanitarian law. This seemingly paradoxical situation illustrates the importance of the objective definition of armed conflict, which has been a defining characteristic of international humanitarian law since 1949.

    Limited knowledge exists about the forces acting on mitral valve annuloplasty repair devices. The aim of this study was to develop a new mitral annular force transducer to measure the forces acting on clinically used mitral valve annuloplasty devices. The design of an X-shaped transducer in the present study was optimized for simultaneous in- and out-of-plane force measurements. Each arm was mounted with strain gauges on four circumferential elements to measure out-of-plane forces, and the central parts of the X-arms were mounted with two strain gauges to measure in-plane forces. A dedicated calibration setup was developed to calibrate isolated forces with tension and compression for in- and out-of-plane measurements. With this setup, it was possible with linear equations to isolate and distinguish measured forces between the two planes and minimize transducer arm crosstalk. An in-vitro test was performed to verify the crosstalk elimination method and the assumptions behind it. The force transducer was implanted and evaluated in an 80kg porcine in-vivo model. Following crosstalk elimination, in-plane systolic force accumulation was found to be in average 4.0±0.1N and the out-of-plane annular segments experienced an average force of 1.4±0.4N. Directions of the systolic out-of-plane forces indicated movements towards a saddle shaped annulus, and the transducer was able to measure independent directional forces in individual annular segments. Further measurements with the new transducer coupled with clinical annuloplasty rings will provide a detailed insight into the biomechanical dynamics of these devices. PMID:26903412

  3. Weak Force

    CERN Multimedia

    Without the weak force, the sun wouldn't shine. The weak force causes beta decay, a form of radioactivity that triggers nuclear fusion in the heart of the sun. The weak force is unlike other forces: it is characterised by disintegration. In beta decay, a down quark transforms into an up quark and an electron is emitted. Some materials are more radioactive than others because the delicate balance between the strong force and the weak force varies depending on the number of particles in the atomic nucleus. We live in the midst of a natural radioactive background that varies from region to region. For example, in Cornwall where there is a lot of granite, levels of background radiation are much higher than in the Geneva region. Text for the interactive: Move the Geiger counter to find out which samples are radioactive - you may be surprised. It is the weak force that is responsible for the Beta radioactivity here. The electrons emitted do not cross the plastic cover. Why do you think there is some detected radioa...

    This study analyzed the biomechanical and physiological effects of the arm swing in roller ski skating, and compared leg-skating (i.e. ski skating without poles) using a pronounced arm swing (SWING) with leg-skating using locked arms (LOCKED). Sixteen elite male cross-country skiers performed submaximal stages at 10, 15 and 20kmh(-1) on a 2% inclined treadmill in the two techniques. SWING demonstrated higher peak push-off forces and a higher force impulse at all speeds, but a longer cycle length only at the highest speed (all Pski skating increases the ski forces and aerobic energy cost at low and moderate speeds, whereas the greater forces at high speed lead to a longer cycle length and smaller anaerobic contribution.

    Institutions formalize the intuitive notion of logical system, including both syntax and semantics. A surprising number of different notions of morphisim have been suggested for forming categories with institutions as objects, and a surprising variety of names have been proposed for them. One goal of this paper is to suggest a terminology that is both uniform and informative to replace the current rather chaotic nomenclature. Another goal is to investigate the properties and interrelations of these notions. Following brief expositions of indexed categories, twisted relations, and Kan extensions, we demonstrate and then exploit the duality between institution morphisms in the original sense of Goguen and Burstall, and the 'plain maps' of Meseguer, obtaining simple uniform proofs of completeness and cocompleteness for both resulting categories; because of this duality, we prefer the name 'comorphism' over 'plain map.' We next consider 'theoroidal' morphisms and comorphisims, which generalize signatures to theories, finding that the 'maps' of Meseguer are theoroidal comorphisms, while theoroidal morphisms are a new concept. We then introduce 'forward' and 'semi-natural' morphisms, and appendices discuss institutions for hidden algebra, universal algebra, partial equational logic, and a variant of order sorted algebra supporting partiality.

To keep ARM at the forefront of climate observations, the ARM infrastructure depends heavily on instrument scientists and engineers, also known as Instrument Mentors. Instrument Mentors must have an excellent understanding of in situ and remote-sensing instrumentation theory and operation and have comprehensive knowledge of critical scale-dependent atmospheric processes. They also possess the technical and analytical skills to develop new data retrievals that provide innovative approaches for creating research-quality data sets.

The Nuclear Non-Proliferation Treaty (NPT), the completion of the Comprehensive Test Ban Treaty (CTBT), and the Chemical Weapons Treaty (CWC) are indicative of the great strides made in the non- proliferation arena. Simultaneously, the Intermediate Nuclear Forces Treaty (INF), the Conventional Forces Treaty in Europe (CFE), and the Strategic Arms Reduction Treaties (START), all associated with US-Soviet Union (now Russia) relations have assisted in redefining European relations and the security landscape. Finally, it now appears that progress is in the offing in developing enhanced compliance measures for the Biological and Toxin Weapons Convention (BTWC). In sum, all of these achievements have set the stage for the next round of arms control activities, which may lead to a much broader, and perhaps more diffused multilateral agenda. In this new and somewhat unpredictable international setting, arms control and disarmament issues will require solutions that are both more creative and innovative than heretofore.

    Full Text Available L’Arménie est une petite république du Caucase, à la limite sud–est de l’Europe, qui a gagné son autonomie en 1990 après l’ouverture du bloc soviétique. Le nouveau Ministère du Patrimoine a sollicité la coopération de la France pour mettre en place une nouvelle politique culturelle. Tout d’abord, une évaluation sur place de la situation dans les domaines des monuments historiques, de l’archéologie et de l’Inventaire a permis d’envisager les réponses à proposer. Pour la demande d’informatisation des dossiers d’inventaire déjà réalisés sous l’autorité de l’Académie de Saint–Petersbourg, nous avons proposé de former des chercheurs arméniens aux méthodes et techniques de l’Inventaire général. L’accueil d’une stagiaire pendant trois mois au service régional de l’Inventaire de Haute–Normandie a été suivi par la mise en place d’un équipement informatique à Yérévan, puis par l’accueil et la formation de techniciens informaticiens et photographes arméniens. De retour dans leur pays ils ont commencé à remettre en place un service d’inventaire dont le programme comprend la création d’une base de données patrimoniales, le recensement de la ville de Yérévan, la numérisation d’images pour la publication d’un indicateur du patrimoine et la préparation de dossiers de protection au titre du patrimoine mondial.The Armenian heritage comprises both archaeological remains of towns destroyed by never–ending wars and a number of old churches from the eleventh and twelfth centuries. Yerevan, the capital of Armenia, was founded three thousand years ago and is one of Europe’s oldest capitals. From 1925 it has developed according to an ambitious urban planning project. After the major political upheavals of 1991, a special ministry was created to look after the architectural and movable heritage of the country and to promote the Armenian national identity.

    The primary objective of this study was to establish the coordinate frame for force control by observing how parameters of force that are not explicitly specified by a motor task vary across the workspace. We asked subjects to apply a force of a specific magnitude with their hand. Subjects could complete the task by applying forces in any direction of their choice in the transverse plane. They were tested with the arm in seven different configurations. To estimate whether contact forces are represented in extrinsic or intrinsic coordinates, we applied the parallel transport method of differential geometry to the net joint torques applied during the task. This approach allowed us to compare the force variability observed at different arm configurations with the force variability that would be expected if the control system were applying an invariant pattern of joint torques at the tested configurations. The results indicate that for the majority of the subjects, the predominant pattern was consistent with an invariant representation in joint coordinates. However, two out of eleven subjects also demonstrated a preference for extrinsic representation. These findings suggest that the central nervous system can represent contact forces in both coordinate frames, with a prevalence toward intrinsic representations.

    Data and metadata standards promote the consistent recording of information and are necessary to ensure the stability and high quality of Atmospheric Radiation Measurement (ARM) Climate Research Facility data products for scientific users. Standards also enable automated routines to be developed to examine data, which leads to more efficient operations and assessment of data quality. Although ARM Infrastructure agrees on the utility of data and metadata standards, there is significant confusion over the existing standards and the process for allowing the release of new data products with exceptions to the standards. The ARM Standards Policy Committee was initiated in March 2012 to develop a set of policies and best practices for ARM data and metadata standards.

    Full Text Available The relative contribution of arm stroke and leg kicking to maximal fully tethered front crawl swimming performance remains to be solved. Twenty-three national level young swimmers (12 male and 11 female randomly performed 3 bouts of 30 s fully tethered swimming (using the whole body, only the arm stroke, and only the leg kicking. A load-cell system permitted the continuous measurement of the exerted forces, and swimming velocity was calculated from the time taken to complete a 50 m front crawl swim. As expected, with no restrictions swimmers were able to exert higher forces than that using only their arm stroke or leg kicking. Estimated relative contributions of arm stroke and leg kicking were 70.3% versus 29.7% for males and 66.6% versus 33.4% for females, with 15.6% and 13.1% force deficits, respectively. To obtain higher velocities, male swimmers are highly dependent on the maximum forces they can exert with the arm stroke (r=0.77, P<0.01, whereas female swimmers swimming velocity is more related to whole-body mean forces (r=0.81, P<0.01. The obtained results point that leg kicking plays an important role over short duration high intensity bouts and that the used methodology may be useful to identify strength and/or coordination flaws.

    Postural sway during quiet stance is attenuated by actively maintained contact of the index finger with a stationary surface, even if the level of applied force (proprioceptive information about the hand and arm can serve as an active sensor of body position relative to the point of contact. A geometric analysis of the relationship between hand and torso displacement during body sway led to the prediction that arm and hand proprioceptive and finger somatosensory information about body sway would be maximized with finger contact in the plane of body sway. Therefore, the most postural stabilization should be possible with such contact. To test this analysis, subjects touched a laterally versus anteriorly placed surface while in each of two stances: the heel-to-toe tandem Romberg stance that reduces medial-lateral stability and the heel-to-heel, toes-outward, knees-bent, "duck stance" that reduces fore-aft stability. Postural sway was always least with finger contact in the unstable plane: for the tandem stance, lateral fingertip contact was significantly more effective than frontal contact, and, for the duck stance, frontal contact was more effective than lateral fingertip contact. Force changes at the fingertip led changes in center of pressure of the feet by approximately 250 ms for both fingertip contact locations for both test stances. These results support the geometric analysis, which showed that 1) arm joint angles change by the largest amount when fingertip contact is maintained in the plane of greatest sway, and 2) the somatosensory cues at the fingertip provide both direction and amplitude information about sway when the finger is contacting a surface in the unstable plane.

    1989-01-01

    Dual-arm satellite grappling involves the integration of technologies developed in the Sensing and Perception (S&P) Subsystem for object acquisition and tracking, and the Manipulator Control and Mechanization (MCM) Subsystem for dual-arm control. S&P acquires and tracks the position, orientation, velocity, and angular velocity of a slowly spinning satellite, and sends tracking data to the MCM subsystem. MCM grapples the satellite and brings it to rest, controlling the arms so that no excessive forces or torques are exerted on the satellite or arms. A 350-pound satellite mockup which can spin freely on a gimbal for several minutes, closely simulating the dynamics of a real satellite is demonstrated. The satellite mockup is fitted with a panel under which may be mounted various elements such as line replacement modules and electrical connectors that will be used to demonstrate servicing tasks once the satellite is docked. The subsystems are housed in three MicroVAX II microcomputers. The hardware of the S&P Subsystem includes CCD cameras, video digitizers, frame buffers, IMFEX (a custom pipelined video processor), a time-code generator with millisecond precision, and a MicroVAX II computer. Its software is written in Pascal and is based on a locally written vision software library. The hardware of the MCM Subsystem includes PUMA 560 robot arms, Lord force/torque sensors, two MicroVAX II computers, and unimation pneumatic parallel grippers. Its software is written in C, and is based on a robot language called RCCL. The two subsystems are described and test results on the grappling of the satellite mockup with rotational rates of up to 2 rpm are provided.

    Previous literature suggests that learning and memory formation can be influenced by diet and exercise. In the current study, we investigated the combined effects of forced swimming exercise (FSE) and every other day fasting (EODF) on spatial memory formation and on the levels of brain-derived neurotrophic factor (BDNF) in the hippocampus of Wistar male rats. The radial arm water maze (RAWM) paradigm was used to assess changes in learning and memory formation, whereas ELISA assay was used to measure BDNF protein levels. The FSE and/or EODF were simultaneously instituted for 6 weeks. Results show that FSE improved learning, short-term as well as long-term memory formation, and significantly increased BDNF protein in the hippocampus (p0.05). In addition, EODF did not modulate beneficial effect of swimming exercise on cognitive function (p>0.05). Thus exercise enhanced, while EODF did not affect spatial learning and memory formation.

    The National Aeronautics and Space Administration (NASA) is developing a robotic mission to visit a large near-Earth asteroid (NEA), collect a multi-ton boulder from its surface, and redirect it into a stable orbit around the Moon. Once returned to cislunar space in the mid-2020s, astronauts will explore the boulder and return to Earth with samples. This Asteroid Redirect Mission (ARM) is part of NASA’s plan to advance the technologies, capabilities, and spaceflight experience needed for a human mission to the Martian system in the 2030s. Subsequent human and robotic missions to the asteroidal material would also be facilitated by its return to cislunar space. Although ARM is primarily a capability demonstration mission (i.e., technologies and associated operations), there exist significant opportunities to advance our knowledge of small bodies in the synergistic areas of science, planetary defense, asteroidal resources and in-situ resource utilization (ISRU), and capability and technology demonstrations. In order to maximize the knowledge return from the mission, NASA is organizing an ARM Investigation Team, which is being preceded by the Formulation Assessment and Support Team. These teams will be comprised of scientists, technologists, and other qualified and interested individuals to help plan the implementation and execution of ARM. An overview of robotic and crewed segments of ARM, including the mission requirements, NEA targets, and mission operations, will be provided along with a discussion of the potential opportunities associated with the mission.

    In this paper, a new approach for a multilayer elastic beam to provide a driving force and driving distance for a MEMS safe and arming system is presented. In particular this is applied where a monolayer elastic beam cannot provide adequate driving force and driving distance at the same time in limited space. Compared with thicker elastic beams, the bilayer elastic beam can provide twice the driving force of a monolayer beam to guarantee the MEMS safe and arming systems work reliably without decreasing the driving distance. In this paper, the theoretical analysis, numerical simulation and experimental verification of the multilayer elastic beam is presented. The numerical simulation and experimental results show that the bilayer elastic provides 1.8–2 times the driving force of a monolayer, and a method that improves driving force without reducing the driving distance.

  14. Scanning ARM Cloud Radar Handbook

    Energy Technology Data Exchange (ETDEWEB)

    Widener, K; Bharadwaj, N; Johnson, K

    2012-06-18

    The scanning ARM cloud radar (SACR) is a polarimetric Doppler radar consisting of three different radar designs based on operating frequency. These are designated as follows: (1) X-band SACR (X-SACR); (2) Ka-band SACR (Ka-SACR); and (3) W-band SACR (W-SACR). There are two SACRs on a single pedestal at each site where SACRs are deployed. The selection of the operating frequencies at each deployed site is predominantly determined by atmospheric attenuation at the site. Because RF attenuation increases with atmospheric water vapor content, ARM's Tropical Western Pacific (TWP) sites use the X-/Ka-band frequency pair. The Southern Great Plains (SGP) and North Slope of Alaska (NSA) sites field the Ka-/W-band frequency pair. One ARM Mobile Facility (AMF1) has a Ka/W-SACR and the other (AMF2) has a X/Ka-SACR.

    Continuous quality control of patient management in the resuscitation room has enabled the Federal Armed Forces Medical Centre Ulm to achieve quality standards that are recognized at both the national and the international levels. This is shown in the fact that the hospital is currently being certified as a supraregional trauma center. A major focus has invariably been placed on interdisaplinarity and compliance with nationally and internationally agreed standards. ATLS @ and PHTLS @ algorithms, which are recognized both nationally and internationally, have been successfully adapted to meet the latest requirements such as a multi-slice CT examination of the whole body and thromboelastography. With this background, medical service officers and non-commissioned officers are able to use the knowledge and skills they have acquired in Ulm also on foreign deployments, which require a particularly high level of flexibility and adaptability.%德国乌尔姆市联邦国防军医疗中心复苏病房对患者实行连续质量控制的医疗处理,此项措施使得该中心的医疗处理工作质量达到了国内和国际先进水平,该院最近被认证为跨地区的创伤医疗中心.医院始终不渝地坚持多学科性建设并保持医疗技术处于国内和国际先进水平.按照国内和国际标准制定的ATIS@和PHTLS@规则系统,例如全身多层CT检查、血栓弹性描记法已被用来满足最新的技术需求.在这样的技术背景下,当部队被派往需要高度的灵活性和适应能力的国外部署时,医务人员和非现役军官就能够充分地运用他们在乌尔姆中心医院获得的知识和技能来完成他们所承担的任务.本文介绍了在复苏病房中对多发性创伤患者进行预处理、为复苏医疗组成员提供培训所需要的现有资源,以及对患者的预处理可获得最佳效果的规则方法,此外还介绍了近十年来为达到现有质量标准所做的改进措施.

Hence the assumptions made in applying the dynamic model to behaviors such as static arm stiffening that leads to arm extension through bend propagation and the patterns of activation used to simulate such behaviors should be modified to account for movements combining bend propagation and arm elongation.

  17. Supporting the President's Arms Control and Nonproliferation Agenda: Transparency and Verification for Nuclear Arms Reductions

    The President's arms control and nonproliferation agenda is still evolving and the details of initiatives supporting it remain undefined. This means that DOE, NNSA, NA-20, NA-24 and the national laboratories can help define the agenda, and the policies and the initiatives to support it. This will require effective internal and interagency coordination. The arms control and nonproliferation agenda is broad and includes the path-breaking goal of creating conditions for the elimination of nuclear weapons. Responsibility for various elements of the agenda will be widely scattered across the interagency. Therefore an interagency mapping exercise should be performed to identify the key points of engagement within NNSA and other agencies for creating effective policy coordination mechanisms. These can include informal networks, working groups, coordinating committees, interagency task forces, etc. It will be important for NA-20 and NA-24 to get a seat at the table and a functional role in many of these coordinating bodies. The arms control and nonproliferation agenda comprises both mature and developing policy initiatives. The more mature elements such as CTBT ratification and a follow-on strategic nuclear arms treaty with Russia have defined milestones. However, recent press reports indicate that even the START follow-on strategic arms pact that is planned to be complete by the end of 2009 may take significantly longer and be more expansive in scope. The Russians called for proposals to count non-deployed as well as deployed warheads. Other elements of the agenda such as FMCT, future bilateral nuclear arms reductions following a START follow-on treaty, nuclear posture changes, preparations for an international nuclear security summit, strengthened international safeguards and multilateral verification are in much earlier stages of development. For this reason any survey of arms control capabilities within the USG should be structured to address potential needs

    From October 1 through September 30, 2016, the Atmospheric Radiation Measurement (ARM) Aerial Facility will deploy the Cessna 206 aircraft over the Southern Great Plains (SGP) site, collecting observations of trace-gas mixing ratios over the ARM’s SGP facility. The aircraft payload includes two Atmospheric Observing Systems, Inc., analyzers for continuous measurements of CO2 and a 12-flask sampler for analysis of carbon cycle gases (CO2, CO, CH4, N2O, 13CO2, 14CO2, carbonyl sulfide, and trace hydrocarbon species, including ethane). The aircraft payload also includes instrumentation for solar/infrared radiation measurements. This research is supported by the U.S. Department of Energy’s ARM Climate Research Facility and Terrestrial Ecosystem Science Program and builds upon previous ARM Airborne Carbon Measurements (ARM-ACME) missions. The goal of these measurements is to improve understanding of 1) the carbon exchange at the SGP site, 2) how CO2 and associated water and energy fluxes influence radiative forcing, convective processes and CO2 concentrations over the SGP site, and 3) how greenhouse gases are transported on continental scales.

At the outbreak of war in September, 1939, the armed forces of the Union consisted of a Permanent Force of 352 Officers and 5033 men, and an Active Citizen Force of 918 Officers and 12 572 men. Of the Permanent Force, 173 Officers and 1664 men formed the South African Air Force, 47 Officers and 562 men were members of the South African Artillery and 17 Officers and 1 705 men formed the Special Service Battalion, a unit consisting of men who served on a short-service basis for a minimum of one year. The rest were concerned principally in the supply services and in administering the Active Citizen Force. The latter was roughly parallel to the Territorial Army in Britain, since membership, although nominally compulsory, was in effect restricted to volunteers from among the various age groups called up annually for compulsory registration. Members of the Active Citizen Force were enrolled in units, some of which could show a history dating back to the middle of the last century, and were required to perform 1½ to 4 hours of non-continuous training per week, and 15 days of continuous training, in camp, each year.

    Full Text Available The single party was the militarized political institution of the new authoritarian regime lead by King Carol II by using the armed hand of single organization in the state, The National Guard. The militarization of policy represented the main dimension of the regime and the state architecture revealed the single party capacity to militarize the administrative institutions. The architecture of National Renaissance Front was similar to a military unit, the official attributions of the National Guard consisted in the maintenance of order in the territory, and unofficially regarded the monitoring of members and opposites of the party and regime, by control and surveillance activity. The National Guard was politicized institution of the regime and of the single party which proved its inefficiency because of the subordination of the commandant general to the single party. Militaries lead the single organization as well as the National Guard.

  3. Structural Optimization of Slender Robot Arm Based on Sensitivity Analysis

    2012-01-01

    Full Text Available An effective structural optimization method based on a sensitivity analysis is proposed to optimize the variable section of a slender robot arm. The structure mechanism and the operating principle of a polishing robot are introduced firstly, and its stiffness model is established. Then, a design of sensitivity analysis method and a sequential linear programming (SLP strategy are developed. At the beginning of the optimization, the design sensitivity analysis method is applied to select the sensitive design variables which can make the optimized results more efficient and accurate. In addition, it can also be used to determine the scale of moving step which will improve the convergency during the optimization process. The design sensitivities are calculated using the finite difference method. The search for the final optimal structure is performed using the SLP method. Simulation results show that the proposed structure optimization method is effective in enhancing the stiffness of the robot arm regardless of the robot arm suffering either a constant force or variable forces.

  4. Unsteady hydrodynamic forces acting on a robotic hand and its flow field.

    2013-07-26

    This study aims to clarify the mechanism of generating unsteady hydrodynamic forces acting on a hand during swimming in order to directly measure the forces, pressure distribution, and flow field around the hand by using a robotic arm and particle image velocimetry (PIV). The robotic arm consisted of the trunk, shoulder, upper arm, forearm, and hand, and it was independently computer controllable in five degrees of freedom. The elbow-joint angle of the robotic arm was fixed at 90°, and the arm was moved in semicircles around the shoulder joint in a plane perpendicular to the water surface. Two-component PIV was used for flow visualization around the hand. The data of the forces and pressure acting on the hand were sampled at 200Hz and stored on a PC. When the maximum resultant force acting on the hand was observed, a pair of counter-rotating vortices appeared on the dorsal surface of the hand. A vortex attached to the hand increased the flow velocity, which led to decreased surface pressure, increasing the hydrodynamic forces. This phenomenon is known as the unsteady mechanism of force generation. We found that the drag force was 72% greater and the lift force was 4.8 times greater than the values estimated under steady flow conditions. Therefore, it is presumable that swimmers receive the benefits of this unsteady hydrodynamic force.

  5. Instituting Commoning

    Directory of Open Access Journals (Sweden)

    . STEALTH.unlimited

    2015-06-01

    Full Text Available Starting from the origins of the notion of management, this paper explores how commons governance is constituted by the earlier influential research of Elinor Ostrom, and pursues this with reference to scholars such as Saki Bailey, who emphasises that the choice of regulatory frame is ultimately a political one. We then argue that commons have to be ‘instituted’ in an open manner in order to remain accessible. This demands a set of scripts, rules or agreements that keep the process of commoning in place, and, simultaneously, keep commoning in a constant process of reproduction. We examine this tension and look at the shift in understanding about what ‘institutions of the commons’ have entailed in practice over the course of the last century and a half. Finally, we return to the political dimension to touch upon the question of whether, with the disappearance of the welfare state, a coherent concept of society can emerge from the current upsurge of commons initiatives.

    2012-01-01

    We study the problem of identifying the top $m$ arms in a multi-armed bandit game. Our proposed solution relies on a new algorithm based on successive rejects of the seemingly bad arms, and successive accepts of the good ones. This algorithmic contribution allows to tackle other multiple identifications settings that were previously out of reach. In particular we show that this idea of successive accepts and rejects applies to the multi-bandit best arm identification problem.

    We present a completely practical TunaDrive piezo motor. It consists of a central piezo stack sandwiched by two arm piezo stacks and two leg piezo stacks, respectively, which is then sandwiched and spring-clamped by a pair of parallel polished sapphire rods. It works by alternatively fast expanding and contracting the arm/leg stacks while slowly expanding/contracting the central stack simultaneously. The key point is that sufficiently fast expanding and contracting a limb stack can make its two sliding friction forces well cancel, resulting in the total sliding friction force is <10% of the total static friction force, which can help increase output force greatly. The piezo motor's high compactness, precision, and output force make it perfect in building a high-quality harsh-condition (vibration resistant) atomic resolution scanning probe microscope.

  11. Nuclear arms race gearing for speedup

    International Nuclear Information System (INIS)

    To probe the rationale behind the big buildup in US strategic arms that is presaged by the current enhanced R and D effort - and to explore the broader, more long-term role of science and technology in the nuclear arms race - C and EN in recent months spoke with a host of experts both within and outside the defense establishment. It is a topic of incredible complexity, high controversy, and of the highest stakes imaginable - the survival of civilization. This buildup will include over the next decade, apart from the MX, a new, highly accurate, submarine-launched ballistic missile and a fleet of very large submarines to carry it; an air-launched cruise missile; a new long-range bomber; a new intermediate-range missile and a new ground-launched cruise missile, both capable of hitting targets in the Soviet Union from proposed bases in Western Europe; and a new sea-launched cruise missile that can be fired from conventional submarines or other naval vessels. To spokesmen for, and members of, the defense establishment the US buildup is prudent, even minimal. According to them, it is needed to keep the US at least on a par with the growth of Soviet strategic might which was very substantial in the 1970's and which will carry over into the 1980's with further major gains. It also is needed to keep the lid on Soviet expansionism; and it is the best way to prevent a nuclear war. To critics, the proposed buildup is the height of lunacy. According to them, the US strategic arsenal is more than adequate today. And it can continue to serve its only legitimate purpose - to deter nuclear war, no matter how much the Soviets may choose to build up their nuclear forces - with a much-more-modest modernization program

  12. Different strategy of hand choice after learning of constant and incremental dynamical perturbation in arm reaching

    2014-02-01

    Full Text Available In daily life, we encounter situations where we must quickly decide which hand to use for a motor action. Here, we investigated whether the hand chosen for a motor action varied over a short timescale (i.e., hours with changes in arm dynamics. Participants performed a reaching task in which they moved a specified hand to reach a target on a virtual reality display. During the task, a resistive viscous force field was abruptly applied to only the dominant hand. To evaluate changes in hand choice caused by this perturbation, participants performed an interleaved choice test in which they could freely choose either hand for reaching. Furthermore, to investigate the effect of temporal changes on arm dynamics and hand choice, we exposed the same participants to another condition in which the force field was introduced gradually. When the abrupt force was applied, use of the perturbed hand significantly decreased and not changed during the training. In contrast, when the incremental force was applied, use of the perturbed hand gradually decreased as force increased. Surprisingly, even though the final amount of force was identical between the two conditions, hand choice was significantly biased toward the unperturbed hand in the gradual condition. These results suggest that time-varying changes in arm dynamics may have a greater influence on hand choice than the amplitude of the resistant force itself.

    The National Aeronautics and Space Administration (NASA) is developing a mission to visit a large near-Earth asteroid (NEA), collect a multi-ton boulder and regolith samples from its surface, demonstrate a planetary defense technique known as the enhanced gravity tractor, and return the asteroidal material to a stable orbit around the Moon. Once returned to cislunar space in the mid-2020s, astronauts will explore the boulder and return to Earth with samples. This Asteroid Redirect Mission (ARM) is part of NASA's plan to advance the technologies, capabilities, and spaceflight experience needed for a human mission to the Martian system in the 2030s and other destinations, as well as provide other broader benefits. Subsequent human and robotic missions to the asteroidal material would also be facilitated by its return to cislunar space. Although ARM is primarily a capability demonstration mission (i.e., technologies and associated operations), there exist significant opportunities to advance our knowledge of small bodies in the synergistic areas of science, planetary defense, asteroidal resources and in-situ resource utilization (ISRU), and capability and technology demonstrations. Current plans are for the robotic mission to be launched in late 2021 with the crewed mission segment conducted using an Orion capsule via a Space Launch System rocket in 2026. In order to maximize the knowledge return from the mission, NASA is providing accommodations for payloads to be carried on the robotic segment of the mission and also organizing an ARM Investigation Team. The Investigation Team will be comprised of scientists, technologists, and other qualified and interested individuals from US industry, government, academia, and international institutions to help plan the implementation and execution of ARM. The presentation will provide a mission overview and the most recent update concerning the robotic and crewed segments of ARM, including the mission requirements, and potential

    Full Text Available Cinema is an act of representation and it is based on the construction of reality inspired by experience. In Colombia, cinema has not been the product of a structured industry, but rather the effort of some filmmakers who have found different ways of telling stories about topics that are part of the national experience. The armed conflict in Colombia, understood as the confrontation between government forces and organized outlawed groups, has prevailed for more than fifty years and has been present in art forms ever since. This research examines a sample of Colombian films to establish the different ways the subject of the armed conflict has been represented in Colombian cinema.

  17. A dynamic model for generating actuator specifications for small arms barrel active stabilization

    Pathak, Anupam; Brei, Diann; Luntz, Jonathan; Lavigna, Chris

    2006-03-01

    Due to stresses encountered in combat, it is known that soldier marksmanship noticeably decreases regardless of prior training. Active stabilization systems in small arms have potential to address this problem to increase soldier survivability and mission effectiveness. The key to success is proper actuator design, but this is highly dependent on proper specification which is challenging due to the human/weapon interaction. This paper presents a generic analytical dynamic model which is capable of defining the necessary actuation specifications for a wide range of small arms platforms. The model is unique because it captures the human interface--shoulder and arm--that introduces the jitter disturbance in addition to the geometry, inertial properties and active stabilization stiffness of the small arms platform. Because no data to date is available for actual shooter-induced disturbance in field conditions, a method is given using the model to back-solve from measured shooting range variability data the disturbance amplitude information relative to the input source (arm or shoulder). As examples of the applicability of the model to various small arms systems, two different weapon systems were investigated: the M24 sniper weapon and the M16 assault rifle. In both cases, model based simulations provided valuable insight into impact on the actuation specifications (force, displacement, phase, frequency) due to the interplay of the human-weapon-active stabilization interface including the effect of shooter-disturbance frequency, disturbance location (shoulder vs. arm), and system parameters (stiffness, barrel rotation).

    2015-01-01

    We study the mechanism of human arm-posture control by means of nonlinear dynamics and quantitative time series analysis methods. Utilizing linear and nonlinear measures in combination, we find that pathological tremors emerge in patient dynamics and serve as a main feature discriminating between normal and patient groups. The deterministic structure accompanied with loss of complexity inherent in the tremor dynamics is also revealed. To probe the underlying mechanism of the arm-posture dynamics, we further analyze the coupling patterns between joints and components, and discuss their roles in breaking of the organization structure. As a result, we elucidate the mechanisms in the arm-posture dynamics of normal subjects responding to the gravitational force and for the reduction of the dynamic degrees of freedom in the patient dynamics. This study provides an integrated framework for the origin of the loss of complexity in the dynamics of patients as well as the coupling structure in the arm-posture dynamics.

    This work identifies the probable strategic characteristics of the interconnected North-Northeast Brazilian electricity industry, after the current restructuring and privatization process has been implemented. It is a 15.0 thousand MW generation industry supplying more than 33.5 million consumers. The normative scenery for analysis of the electricity industry takes into consideration the premises that the government establishes the vertical separation of generation, transmission, distribution and retailing, and introduces the regulation to a competitive industrial structure in generation and retailing. It is assumed that free access to transmit and distribute electricity and broad choices for consumers are the main features for competition in both generation and retailing. The essence of formulating strategy is to relate a company with its environment, considering the industrial structure. Porter's five forces model for industry environment and competition, emphasizing the role of the government in such regulated industry, is the basic theoretical reference. The main strategic characteristics related to entry barriers, rivalry intensity, supplier power, customer power and substitute products are analyzed. (author)

  1. Piezoresistive Tactile Sensor Discriminating Multidirectional Forces

    Directory of Open Access Journals (Sweden)

    2015-10-01

    Full Text Available Flexible tactile sensors capable of detecting the magnitude and direction of the applied force together are of great interest for application in human-interactive robots, prosthetics, and bionic arms/feet. Human skin contains excellent tactile sensing elements, mechanoreceptors, which detect their assigned tactile stimuli and transduce them into electrical signals. The transduced signals are transmitted through separated nerve fibers to the central nerve system without complicated signal processing. Inspired by the function and organization of human skin, we present a piezoresistive type tactile sensor capable of discriminating the direction and magnitude of stimulations without further signal processing. Our tactile sensor is based on a flexible core and four sidewall structures of elastomer, where highly sensitive interlocking piezoresistive type sensing elements are embedded. We demonstrate the discriminating normal pressure and shear force simultaneously without interference between the applied forces. The developed sensor can detect down to 128 Pa in normal pressure and 0.08 N in shear force, respectively. The developed sensor can be applied in the prosthetic arms requiring the restoration of tactile sensation to discriminate the feeling of normal and shear force like human skin.

    The human migrations have been one of the motors in the history of humanity. During the twentieth century, internal forced displacement has been an important component of the migration processes in the world. Colombia, a paradigm for this phenomenon, is a country with more than three and a half million people displaced over the last 25 years by force of the violence resulting from an internal armed conflict. Besides the socio-demographic effects in the reconfiguration of the cities, this problem affects the human condition of the victims deteriorating their health and quality of life. This article aims to show the general panorama of migrations forced by violence in the world and to analyze the peculiarities of this phenomenon in the Colombian case. We conclude that forced displacement is a serious violation of human rights producing a human drama by exposing the affected individuals and communities to vulnerability and a deep deterioration of their quality of life and health.

    1995-01-01

    The described and improved multi-arm invention of this application presents three strategies for adaptive control of cooperative multi-arm robots which coordinate control over a common load. In the position-position control strategy, the adaptive controllers ensure that the end-effector positions of both arms track desired trajectories in Cartesian space despite unknown time-varying interaction forces exerted through a load. In the position-hybrid control strategy, the adaptive controller of one arm controls end-effector motions in the free directions and applied forces in the constraint directions; while the adaptive controller of the other arm ensures that the end-effector tracks desired position trajectories. In the hybrid-hybrid control strategy, the adaptive controllers ensure that both end-effectors track reference position trajectories while simultaneously applying desired forces on the load. In all three control strategies, the cross-coupling effects between the arms are treated as disturbances which are compensated for by the adaptive controllers while following desired commands in a common frame of reference. The adaptive controllers do not require the complex mathematical model of the arm dynamics or any knowledge of the arm dynamic parameters or the load parameters such as mass and stiffness. Circuits in the adaptive feedback and feedforward controllers are varied by novel adaptation laws.

  7. Hot Galactic Arms Point To Vicious Cycle

    Science.gov (United States)

    2001-12-01

    NASA's Chandra X-ray Observatory has revealed the aftermath of a titanic explosion that wracked the elliptical galaxy known as NGC 4636. This eruption could be the latest episode in a cycle of violence that is triggered by gas falling into a central massive black hole. Chandra's images of NGC 4636 show spectacular symmetric arms, or arcs, of hot gas extending 25,000 light years into a huge cloud of multimillion-degree-Celsius gas that envelopes the galaxy. At a temperature of 10 million degrees, the arms are 30 percent hotter than the surrounding gas cloud. "The temperature jump, together with the symmetry and scale of the arms, suggests that we are observing the effects of a tremendous outburst that occurred in the center of the galaxy," said Christine Jones of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., lead author of a paper on these observations scheduled for publication in Astrophysical Journal Letters. "The energy of this explosion would be the equivalent of several hundred thousand supernovas." The arms appear to be the leading edges of a galaxy-sized shock wave that is racing outward at 700 kilometers per second, or 1.6 million miles per hour. At this speed, it would take 3 million years for the structures to attain their present size. Cavities detected in the hot gas cloud to the east and west of the center of the galaxy support the shockwave explanation. The authors suggest that the explosion is part of a majestic cosmic feedback process that keeps the galaxy in a state of turmoil. Over a period of a few million years, a hot gas cloud that envelops the stars in the galaxy cools and falls inward toward a central, massive black hole. The feeding of the black hole by the infalling material leads to an explosion that heats the hot gaseous envelope, starting the cycle anew. NGC 4636 NGC 4636 Background Subtracted This feedback cycle may explain one puzzling feature of the galaxy - the lack of a strong radio source of the type that is

  8. Segregation of chromosome arms in growing and non-growing Escherichia coli cells

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available In slow-growing Escherichia coli cells the chromosome is organized with its left (L and right (R arms lying separated in opposite halves of the nucleoid and with the origin (O in-between, giving the pattern L-O-R. During replication one of the arms has to pass the other to obtain the same organization in the daughter cells: L-O-R L-O-R. To determine the movement of arms during segregation six strains were constructed carrying three coloured loci: the left and right arms were labeled with red and cyan fluorescent-proteins, respectively, on loci symmetrically positioned at different distances from the central origin, which was labeled with green-fluorescent protein. In non-replicating cells with the predominant spot pattern L-O-R, initiation of replication first resulted in a L-O-O-R pattern, soon changing to O-L-R-O. After replication of the arms the predominant spot patterns were, L-O-R L-O-R, O-R-L R-O-L or O-L-R L-O-R indicating that one or both arms passed an origin and the other arm. To study the driving force for these movements cell growth was inhibited with rifampicin allowing run-off DNA synthesis. Similar spot patterns were obtained in growing and non-growing cells, indicating that the movement of arms is not a growth-sustained process, but may result from DNA synthesis itself. The distances between loci on different arms (LR-distances and between duplicated loci (LL- or RR-distances as a function of their distance from the origin, indicate that in slow-growing cells DNA is organized according to the so-called sausage model and not accordingto the doughnut model.

    1986-05-01

    This report reviews the arms-control policy and decision-making process of the last several administrations with the emphasis on how frictional forces, not unlike those discussed by von Clausewitz, affect the process. It is discusses friction within administrations, as a result of Congressional actions, from nongovernmental organizations, and from the media. Friction is present in every process involving individuals and organizations with differing views and objectives. It may not be desirable to remove all friction from the process, even if it were possible to do so, lest the decision makers stifle creativity and lose the benefit of a variety of views and approaches.

  14. Bionic robot arm with compliant actuators

    Science.gov (United States)

    Moehl, Bernhard

    2000-10-01

    Traditional robotics uses non-compliant materials for all components involved in the production of movement. Elasticity is avoided as far as possible, because it leads to hazardous oscillations and makes control of precise movements very difficult. Due to this deliberate stiffness, robots are typically heavy and clumsy structures in comparison to their living counterparts (i.e. man and animals). Yet, moving systems in nature cope not only with the difficulties introduced by compliant materials, they also take advantage of the elasticity in muscles and tendons to produce smooth and even rapid movements. It is understood, that elasticity in a multi-jointed moving system requires sophisticated control mechanisms- as provided by a nervous system or a suitably programmed computer. In this contribution I shall describe a two-jointed robot with purpose-built elasticity in its actuators. This is accomplished by spiral springs places in series with a conventional electric motor and a tendon to the arm. It is shown that, with sufficiently soft elasticity, oscillations can be avoided by active oscillation damping. (Such active oscillation damping presumably also governs movement control in man and animals.) Furthermore, once the major problem has been overcome, elasticity is found to offer a wide spectrum of valuable advantages, as far as the most serious problems in traditional robotics are concerned. They are summarized by terms such as less dangerous, position tolerant, lightweight construction, controlled forces, and ballistic movements. These will be explained in detail and presented for discussion.

    2013-01-01

    Background Tennis elbow (TE) is a common musculotendinous degenerative disorder of the extensor origin at the lateral humeral epicondyle. Different modes of treatment are used for management of tennis elbow. Objectives This study investigated the effect of the taping technique (TT) on pain, grip strength and wrist extension force in treatment of tennis elbow. Patients and Methods Thirty patients (16 men /14 women with a mean age of 32.2 years) with tennis elbow of their dominant arm participated in this study. Outcome measures were assessment of pain at the lateral aspect of the elbow, grip strength and wrist extension force before and five to ten minutes after application of elbow tape on the affected and unaffected arms. A Visual Analog Scale was used to assess pain. A dynamometer and a hand-held dynamometer were used for evaluation of grip strength and wrist extension force, respectively. Results Among the variables, significant differences were found in wrist extension forces between effected and unaffected arms (P = 0.02). Changes in grip strength showed statically significant improvements in the affected arm compared to the unaffected arm (P = 0.03). Also, in assessment of pain at the lateral epicondyle, the mean change between affected and unaffected arms was significant, with P = 0.001. Conclusions The taping technique, as applied in this study demonstrates an impressive effect on wrist extension force and grip strength of patients with TE. Elbow taping also reduces pain at the lateral aspect of the elbow in these patients. PMID:24350156

  18. Learning and Control Model of the Arm for Loading

    Science.gov (United States)

    Kim, Kyoungsik; Kambara, Hiroyuki; Shin, Duk; Koike, Yasuharu

    We propose a learning and control model of the arm for a loading task in which an object is loaded onto one hand with the other hand, in the sagittal plane. Postural control during object interactions provides important points to motor control theories in terms of how humans handle dynamics changes and use the information of prediction and sensory feedback. For the learning and control model, we coupled a feedback-error-learning scheme with an Actor-Critic method used as a feedback controller. To overcome sensory delays, a feedforward dynamics model (FDM) was used in the sensory feedback path. We tested the proposed model in simulation using a two-joint arm with six muscles, each with time delays in muscle force generation. By applying the proposed model to the loading task, we showed that motor commands started increasing, before an object was loaded on, to stabilize arm posture. We also found that the FDM contributes to the stabilization by predicting how the hand changes based on contexts of the object and efferent signals. For comparison with other computational models, we present the simulation results of a minimum-variance model.

    To achieve its long-term goal of sending humans to Mars, the National Aeronautics and Space Administration (NASA) plans to proceed in a series of incrementally more complex human spaceflight missions. Today, human flight experience extends only to Low-Earth Orbit (LEO), and should problems arise during a mission, the crew can return to Earth in a matter of minutes to hours. The next logical step for human spaceflight is to gain flight experience in the vicinity of the Moon. These cis-lunar missions provide a "proving ground" for the testing of systems and operations while still accommodating an emergency return path to the Earth that would last only several days. Cis-lunar mission experience will be essential for more ambitious human missions beyond the Earth-Moon system, which will require weeks, months, or even years of transit time. In addition, NASA has been given a Grand Challenge to find all asteroid threats to human populations and know what to do about them. Obtaining knowledge of asteroid physical properties combined with performing technology demonstrations for planetary defense provide much needed information to address the issue of future asteroid impacts on Earth. Hence the combined objectives of human exploration and planetary defense give a rationale for the Asteroid Re-direct Mission (ARM). Mission Description: NASA's ARM consists of two mission segments: 1) the Asteroid Redirect Robotic Mission (ARRM), the first robotic mission to visit a large (greater than ~100 m diameter) near-Earth asteroid (NEA), collect a multi-ton boulder from its surface along with regolith samples, demonstrate a planetary defense technique, and return the asteroidal material to a stable orbit around the Moon; and 2) the Asteroid Redirect Crewed Mission (ARCM), in which astronauts will take the Orion capsule to rendezvous and dock with the robotic vehicle, conduct multiple extravehicular activities to explore the boulder, and return to Earth with samples.

    Octopuses are molluscs that belong to the group Cephalopoda. They lack joints and rigid links, and as a result, their arms possess virtually limitless freedom of movement. These flexible appendages exhibit peculiar biomechanical features such as stiffness control, compliance, and high flexibility and dexterity. Studying the capabilities of the octopus arm is a complex task that presents a challenge for both biologists and roboticists, the latter of whom draw inspiration from the octopus in designing novel technologies within soft robotics. With this idea in mind, in this study, we used new, purposively developed methods of analysing the octopus arm in vivo to create new biologically inspired design concepts. Our measurements showed that the octopus arm can elongate by 70% in tandem with a 23% diameter reduction and exhibits an average pulling force of 40 N. The arm also exhibited a 20% mean shortening at a rate of 17.1 mm s(-1) and a longitudinal stiffening rate as high as 2 N (mm s)(-1). Using histology and ultrasounds, we investigated the functional morphology of the internal tissues, including the sinusoidal arrangement of the nerve cord and the local insertion points of the longitudinal and transverse muscle fibres. The resulting information was used to create novel design principles and specifications that can in turn be used in developing a new soft robotic arm.

    2016-01-01

    Full Text Available In this study, 2 DOF mathematical models of Pitman arm steering system are derived using Newton’s law of motion and modeled in MATLAB/SIMULINK software. The developed steering model is included with a DC motor model which is directly attached to the steering column. The Pitman arm steering model is then validated with actual Pitman arm steering test rig using various lateral inputs such as double lane change, step steer, and slalom test. Meanwhile, a position tracking control method has been used in order to evaluate the effectiveness of the validated model to be implemented in active safety system of a heavy vehicle. The similar method has been used to test the actual Pitman arm steering mechanism using hardware-in-the-loop simulation (HILS technique. Additional friction compensation is added in the HILS technique in order to minimize the frictional effects that occur in the mechanical configuration of the DC motor and Pitman arm steering. The performance of the electronically actuated Pitman arm steering system can be used to develop a firing-on-the-move actuator (FOMA for an armored vehicle. The FOMA can be used as an active safety system to reject unwanted yaw motion due to the firing force.

    Humanoid robots are designed and built to mimic human form and movement.Ultimately,they are meant to resemble the size and physical abilities of a human in order to function in human-oriented environments and to work autonomously but to pose no physical threat to humans.Here,a humanoid robot that resembles a human in appearance and movement is built using powerful actuators paired with gear trains,joint mechanisms,and motor drivers that are all encased in a package no larger than that of the human physique.In this paper,we propose the construction of a humanoid-applicable anthropomorphic 7-DoF arm complete with an 8-DoF hand.The novel mechanical design of this humanoid arm makes it sufficiently compact to be compatible with currently available narrating-model humanoids,and to be sufficiently powerful and flexible to be functional; the number of degrees of freedom endowed in this robotic arm is sufficient for executing a wide range of tasks,including dexterous hand movements.The developed humanoid arm and hand are capable of sensing and interpreting incoming external force using the motor in each joint current without conventional torque sensors.The humanoid arm adopts an algorithm to avoid obstacles and the dexterous hand is capable of grasping objects.The developed robotic arm is suitable for use in an interactive humanoid robot.

  6. Changing patterns of US arms transfers

    Salomone, M.D.

    1985-01-01

    The thesis has three purposes. First is to explore the changing patterns of US arms transfers from Fiscal Year 1950 (FY 1950) through Fiscal Year 1980 (FY 1980). Second, is to describe and assess the decision-making process for arms transfers within the US Government. Third is to examine and critique the conventional wisdom concerning US arms transfers, to support that wisdom, or to offer an alternate empirically supported view. The conventional wisdom about US arms transfer is that they have been rising at an alarming rate, and that this is the result of an arms transfer decision-making process which is out of control. This belief is founded on an empirically based proposition that arms transfers have been rising at an alarming rate. However, this proposition has never been empirically validated. To explore this conventional wisdom, the author establishes the historical, political and defense policy contexts for US arms transfers over the period FY 1950 through FY 1980. The author critiques the conventional wisdom about US arms transfers, analyzes the many ways that arms transfers have been measured, and explores the impediments to accurate measurement and assessment of the phenomenon.

    1995-01-01

    The European Robotic Arm (ERA) is a contribution to the Russian Segment of the International Space Station Alpha. It will start operating on the Russian Segment during the assembly phase. ERA is designed and produced by a large industrial consortium spread over Europe with Fokker Space & Systems as prime contractor. In this paper, we will describe some of the overall design aspects and focus on the development of several mechanisms within ERA. The operation of ERA during the approach of its end effector towards the grapple interface and the grapple operation is discussed, with a focus on mechanisms. This includes the geometry of the end effector leading edge, which is carefully designed to provide the correct and complete tactile information to a torque-force sensor (TFS). The data from this TFS are used to steer the arm such that forces and moments are kept below 20 N and 20 N.m respectively during the grappling operation. Two hardware models of the end effector are built. The problems encountered are described as well as their solutions. The joints in the wrists and the elbow initially used a harmonic drive lubricated by MoS2. During development testing, this combination showed an insufficient lifetime in air to survive the acceptance test program. The switch-over to a system comprising planetary gearboxes with grease lubrication is described. From these development efforts, conclusions are drawn and recommendations are given for the design of complex space mechanisms.

    1989-01-01

    The KALI distributed robot programming and control environment is described within the context of its use in the Jet Propulsion Laboratory (JPL) telerobot project. The purpose of KALI is to provide a flexible robot programming and control environment for coordinated multi-arm robots. Flexibility, both in hardware configuration and software, is desired so that it can be easily modified to test various concepts in robot programming and control, e.g., multi-arm control, force control, sensor integration, teleoperation, and shared control. In the programming environment, user programs written in the C programming language describe trajectories for multiple coordinated manipulators with the aid of KALI function libraries. A system of multiple coordinated manipulators is considered within the programming environment as one motion system. The user plans the trajectory of one controlled Cartesian frame associated with a motion system and describes the positions of the manipulators with respect to that frame. Smooth Cartesian trajectories are achieved through a blending of successive path segments. The manipulator and load dynamics are considered during trajectory generation so that given interface force limits are not exceeded.

    We investigated whether slower velocity of arm movement affects grip-force generation in conditions with the finger touch provided to the wrist of the target arm. Nine subjects performed the task of lifting and transporting an object at slow, intermediate, and fast velocities with a light finger touch from the contralateral arm and without it. There was an effect of velocity of arm movement on grip-force generation in both conditions. However, when the no touch and touch trials performed with similar velocity were matched, the effect of touch on grip-force reduction was statistically significant (p touch conditions and underlines the importance of using a contralateral touch in the performance of activities of daily living. It also points to a possibility of the development of therapeutic advances for the enhancement of grip-force control in patients with neurological impairments.

    The most commonly used propulsion method for handcycling is moving the arms symmetrically. Previous studies indicated that during outdoor handcycling symmetrical arm movements are more efficient. During locomotor movements, however, arm movements are performed asymmetrically in combination with leg movements. We questioned which combination of arm and leg movements is more efficient during combined arm and leg cycling for stationary use.

  14. Tangential finger forces use mechanical advantage during static grasping.

    Science.gov (United States)

    Slota, Gregory P; Latash, Mark L; Zatsiorsky, Vladimir M

    2012-02-01

    When grasping and manipulating objects, the central controller utilizes the mechanical advantage of the normal forces of the fingers for torque production. Whether the same is valid for tangential forces is unknown. The main purpose of this study was to determine the patterns of finger tangential forces and the use of mechanical advantage as a control mechanism when dealing with objects of nonuniform finger positioning. A complementary goal was to explore the interaction of mechanical advantage (moment arm) and the role a finger has as a torque agonist/antagonist with respect to external torques (±0.4 N m). Five 6-df force/torque transducers measured finger forces while subjects held a prism handle (6 cm width × 9 cm height) with and without a single finger displaced 2 cm (handle width). The effect of increasing the tangential moment arm was significant (p forces (in >70% of trials) and hence creating greater moments. Thus, the data provides evidence that the grasping system as a rule utilizes mechanical advantage for generating tangential forces. The increase in tangential force was independent of whether the finger was acting as a torque agonist or antagonist, revealing their effects to be additive.

    This paper reports the rationale and design of a robotic arm, as inspired by an octopus arm. The octopus arm shows peculiar features, such as the ability to bend in all directions, to produce fast elongations, and to vary its stiffness. The octopus achieves these unique motor skills, thanks to its peculiar muscular structure, named muscular hydrostat. Different muscles arranged on orthogonal planes generate an antagonistic action on each other in the muscular hydrostat, which does not change its volume during muscle contractions, and allow bending and elongation of the arm and stiffness variation. By drawing inspiration from natural skills of octopus, and by analysing the geometry and mechanics of the muscular structure of its arm, we propose the design of a robot arm consisting of an artificial muscular hydrostat structure, which is completely soft and compliant, but also able to stiffen. In this paper, we discuss the design criteria of the robotic arm and how this design and the special arrangement of its muscular structure may bring the building of a robotic arm into being, by showing the results obtained by mathematical models and prototypical mock-ups.

  18. Why we cannot grow a human arm.

    Science.gov (United States)

    Ricci, John L

    2013-11-01

    There are several significant issues that prevent us from growing a human arm now, or within the next 10-20 years. From a tissue engineering perspective, while we can grow many of the components necessary for construction of a human arm, we can only grow them in relatively small volumes, and when scaled up to large volumes we lack the ability to develop adequate blood/nerve supply. From a genetic engineering perspective, we will probably never be able to turn on the specific genes necessary to "grow an arm" unless it is attached to a fetus and this presents enormous ethical issues related to farming of human organs and structures. Perhaps the most daunting problem facing the transplantation of a tissue engineered or transplanted arm is that of re-innervation of the structure. Since the sensory and motor nerve cells of the arm are located outside of the structure, re-innervation requires those nerves to regenerate over relatively large distances to repopulate the nervous system of the arm. This is something with which we have had little success. We can grow repair parts, but "growing an arm" presents too many insurmountable problems. The best we could possibly do with tissue engineering or genetic engineering would be the equivalent of a fetal arm and the technical problems, costs, and ethical hurdles are enormous. A more likely solution is a functional, permanent, neuroelectronically-controlled prosthesis. These are nearly a reality today.

    This paper analyzes the phenomenon of “forced migration” in Malaysia. It examines the nature of forced migration, the challenges faced by Malaysia, the policy responses and their impact on the country and upon the forced migrants. It considers forced migration as an event hosting multifaceted issues related and relevant to forced migrants and suggests that Malaysia has been preoccupied with the issue of forced migration movements. This is largely seen in various responses invoked from Malaysi...

    The advancements in fields like robotics and medicine continuously require improvements of sensor devices and more engagement of cooperative sensing technologies. For example, instruments such as tweezers with sensitive force sensory heads could provide the ability to sense a variety of physical quantities in real time, such as the amount and direction of the force applied or the texture of the gripped object. Force sensors with such abilities could be great solutions toward the development of smart surgical tools. In this work, a unique force sensor that can be integrated at the tips of robotic arms or surgical tools is reported. The force sensor consists of a single bioinspired, permanent magnetic and highly elastic nanocomposite cilia integrated on a magnetic field sensing element. The nanocomposite is prepared from permanent magnetic nanowires incorporated into the highly elastic polydimethylsiloxane. We demonstrate the potential of this concept by performing several experiments to show the performance of the force sensor. The developed sensor element has a 200 μm in diameter single cilium with 1:5 aspect ratio and shows a detection range up to 1 mN with a sensitivity of 1.6 Ω/mN and a resolution of 31 μN. The simple fabrication process of the sensor allows easy optimization of the sensor performance to meet the needs of different applications.

For these reasons, early developments in cosmetic and body-driven prostheses date some centuries ago, and they have been evolving ever since. Following the end of the Second World War, rapid developments in technology resulted in powered myoelectric hand prosthetics. In the years to come, these devices were common on the market, though they still suffered high user abandonment rates. The reasons for rejection were trifold – insufficient functionality of the hardware, fragile design, and cumbersome control. In the last decade, both academia and industry have reached major improvements concerning technical features of upper limb prosthetics and methods for their interfacing and control. Advanced robotic hands are offered by several vendors and research groups, with a variety of active and passive wrist options that can be articulated across several degrees of freedom. Nowadays, elbow joint designs include active solutions with different weight and power options. Control features are getting progressively more sophisticated, offering options for multiple sensor integration and multi-joint articulation. Latest developments in socket designs are capable of facilitating implantable and multiple surface electromyography sensors in both traditional and osseointegration-based systems. Novel surgical techniques in combination with modern, sophisticated hardware are enabling restoration of dexterous upper limb

    At the University of Florida we developed the University of Florida LISA Interferometer Simulator (UFLIS) in order to study LISA interferometry with hardware in the loop at a system level. One of the proposed laser frequency stabilization techniques in LISA is arm locking. Arm locking uses an adequately filtered linear combination of the LISA arm signals as a frequency reference. We will report about experiments in which we demonstrated arm locking using UFLIS. During these experiments we also discovered a problem associated with the Doppler shift of the return beam. The initial arm locking publications assumed that this Doppler shift can perfectly be subtracted inside the phasemeter or adds an insignificant offset to the sensor signal. However, the remaining Doppler knowledge error will cause a constant change in the laser frequency if unaccounted for. Several ways to circumvent this problem have been identified. We performed detailed simulations and started preliminary experiments to verify the performance of the proposed new controller designs.

    Full Text Available The report focuses on the design and demonstration of an anthropomorphic robotic arm with seven degrees of freedom using readily available low-cost components to perform different real time human hand applications. The robotic arm consists of a shoulder, elbow, wrist and a five-finger gripper. It can perform different gripping actions, such as lateral, spherical, cylindrical and tip-holding gripping actions; each finger has three movable links. The actuator used for the robotic arm is a high torque dc servo motor and the five-finger gripper consists of five cables placed like tendons in the human arm. Implementation is done using a human hand glove which senses the motion from sensor technology to produce a proportional analog voltage, digitized via the microcontroller Atmel ATmega32. The microcontroller then through the processed signal controls the mechanical structure that is the robotic arm. Keywords –

    2013-01-01

    We study the influuence of the forcing on the steady turbulent states of a von K\\'arm\\'an swirling flow, at constant impeller speed, or at constant torque. We find that the different forcing conditions change the nature of the stability of the steady states and reveal dynamical regimes that bear similarities with low-dimensional systems. We suggest that this forcing dependence may be an out- of-equilibrium analogue of the ensemble inequivalence, valid for long-range interacting statistical systems, and that it may be applicable to other turbulent systems.

  10. Geometric Clutch model version 3: the role of the inner and outer arm dyneins in the ciliary beat.

    Science.gov (United States)

    Lindemann, Charles B

    2002-08-01

    The Geometric Clutch model of ciliary and flagellar beating uses the transverse force (t-force) that develops between the outer doublets of the axoneme as the regulator for activating and deactivating the dynein motors and organizing the flagellar beat. The version of the model described here adds detail to the formulations used in the two previous versions as follows: (1) In place of two opposing sets of dyneins, the new model has four sets of dyneins, corresponding to two sets on each side of the axoneme acting in series. (2) The four sets of dyneins are each subdivided into two ranks representing inner and outer arm dyneins. (3) The force produced by each dynein is governed by a force-velocity relationship that is independently specified for the inner and outer arms. Consistent with the original model, the new version of the Geometric Clutch model can simulate both the effective and recovery stroke phases of the ciliary beat using a single uniform algorithm. In addition, the new version can operate with the outer arms disabled. Under this condition, the simulation exhibits a beat pattern similar to the original but the beat frequency is reduced to approximately one third. These results are contingent on using force-velocity relationships for the inner and outer arms similar to those described by Brokaw [1999: Cell Motil. Cytoskeleton 42:134-148], where the inner arms contribute most of the driving force at low shear velocities. This constitutes the first examination of the effects of the force-velocity characteristics of dynein on a cilia-like beat in a theoretical framework. PMID:12112138

    We present a completely practical TunaDrive piezo motor. It consists of a central piezo stack sandwiched by two arm piezo stacks and two leg piezo stacks, respectively, which is then sandwiched and spring-clamped by a pair of parallel polished sapphire rods. It works by alternatively fast expanding and contracting the arm/leg stacks while slowly expanding/contracting the central stack simultaneously. The key point is that sufficiently fast expanding and contracting a limb stack can make its two sliding friction forces well cancel, resulting in the total sliding friction force is piezo motor's high compactness, precision, and output force make it perfect in building a high-quality harsh-condition (vibration resistant) atomic resolution scanning probe microscope.

    2014-01-01

    This essay intends to offer a comment on concepts, trends and attitudes concerning arms control and strategic stability with reference to the current international security situation. It also offers observations from two different perspectives about strategic stability: one proceeds from the concept of universal security and aims to prevent conflicts and instability from disrupting regional and international security environment on which nation states depend so much for their peaceful development; the other starts from maintaining the global leadership by a super power and aiming to contain any challenge that sways or is likely to sway its dominating status. If China and the United States commit themselves to the undertaking of a new type of major powers relationship that stresses win-win cooperation, they will be able to contribute greatly to a stable international security architecture that is good for world peaceful development.

  14. Arms control and the rule of law

    International Nuclear Information System (INIS)

    Many who speak of the end of the Cold War emphasize the warming of international relations when they speak of the momentous consequences of this event. According to this image, the half century since Trinity has been a period of sparse international communication during which the Eastern and Western blocs hibernated in their isolated dens of security alliances. Yet it is equally valid to consider the implications of the end of the war footing that has underlain the policies of all of the major military powers during the last fifty years. While meaningful international dialogue was in a state of relative lethargy during much of this period, the military establishments of the Great Powers were actively engaged in using as much force as possible in their efforts to control world affairs, short of triggering a nuclear holocaust. International discourse, at least in English, was rife with such military images as appeasement, containment, crisis stability, and tripwires. From the military posture of the U.S. and Russia a tense peace ironically emerged, but the terms by which decisions were made about controlling weapons of mass destruction (i.e., nuclear, chemical, and biological weapons) were the terms of war. The thesis of this paper is that the end of the Cold War marks a shift away from reliance on military might toward an international commitment to control weapons of mass destruction through the rule of law developed by John Rawls. The progression of agreements during this century to limit weapons of mass destruction testifies to this new development.

    The automatic polishing process for three-dimensional forms, such as prototype models of products made of acrylic resin, are being required to develop in order to reduce cost and time consumption. This paper proposes a new polishing technique using magnetic compound fluid (MCF) and robotic arm. Firstly, a polishing unit, which can generate a dynamic magnetic field and be attachable to the robotic arm, is developed. This unit can hold MCF slurry that acts as a flexible and restorable polishing tool for the sake of magnetic force. Secondly, the effects of the clearance between workpiece and polishing unit, the composition of MCF slurry, the relative motion, the dynamic magnetic field and the supplied amount of slurry on polishing characteristics of acrylic resin are experimentally demonstrated. As a result, the smoothest surface roughness is achieved to below 10 nm Ra in a few min, and the feasibility of polishing the free-formed device by controlling robotic arm has been confirmed.

  17. Secretory vesicle transport velocity in living cells depends on the myosin-V lever arm length.

    Myosins are molecular motors that exert force against actin filaments. One widely conserved myosin class, the myosin-Vs, recruits organelles to polarized sites in animal and fungal cells. However, it has been unclear whether myosin-Vs actively transport organelles, and whether the recently challenged lever arm model developed for muscle myosin applies to myosin-Vs. Here we demonstrate in living, intact yeast that secretory vesicles move rapidly toward their site of exocytosis. The maximal speed varies linearly over a wide range of lever arm lengths genetically engineered into the myosin-V heavy chain encoded by the MYO2 gene. Thus, secretory vesicle polarization is achieved through active transport by a myosin-V, and the motor mechanism is consistent with the lever arm model.

  18. Phylogeny of diving beetles reveals a coevolutionary arms race between the sexes.

    Directory of Open Access Journals (Sweden)

    Johannes Bergsten

    Full Text Available BACKGROUND: Darwin illustrated his sexual selection theory with male and female morphology of diving beetles, but maintained a cooperative view of their interaction. Present theory suggests that instead sexual conflict should be a widespread evolutionary force driving both intersexual coevolutionary arms races and speciation. METHODOLOGY/PRINCIPAL FINDINGS: We combined Bayesian phylogenetics, complete taxon sampling and a multi-gene approach to test the arms race scenario on a robust diving beetle phylogeny. As predicted, suction cups in males and modified dorsal surfaces in females showed a pronounced coevolutionary pattern. The female dorsal modifications impair the attachment ability of male suction cups, but each antagonistic novelty in females corresponds to counter-differentiation of suction cups in males. CONCLUSIONS: A recently diverged sibling species pair in Japan is possibly one consequence of this arms race and we suggest that future studies on hypoxia might reveal the key to the extraordinary selection for female counter-adaptations in diving beetles.

    To achieve its long-term goal of sending humans to Mars, the National Aeronautics and Space Administration (NASA) plans to proceed in a series of incrementally more complex human spaceflight missions. Today, human flight experience extends only to Low-Earth Orbit (LEO), and should problems arise during a mission, the crew can return to Earth in a matter of minutes to hours. The next logical step for human spaceflight is to gain flight experience in the vicinity of the Moon. These cis-lunar missions provide a "proving ground" for the testing of systems and operations while still accommodating an emergency return path to the Earth that would last only several days. Cis-lunar mission experience will be essential for more ambitious human missions beyond the Earth-Moon system, which will require weeks, months, or even years of transit time. In addition, NASA has been given a Grand Challenge to find all asteroid threats to human populations and know what to do about them. Obtaining knowledge of asteroid physical properties combined with performing technology demonstrations for planetary defense provide much needed information to address the issue of future asteroid impacts on Earth. Hence the combined objectives of human exploration and planetary defense give a rationale for the Asteroid Re-direct Mission (ARM). Mission Description: NASA's ARM consists of two mission segments: 1) the Asteroid Redirect Robotic Mission (ARRM), the first robotic mission to visit a large (greater than ~100 m diameter) near-Earth asteroid (NEA), collect a multi-ton boulder from its surface along with regolith samples, demonstrate a planetary defense technique, and return the asteroidal material to a stable orbit around the Moon; and 2) the Asteroid Redirect Crewed Mission (ARCM), in which astronauts will take the Orion capsule to rendezvous and dock with the robotic vehicle, conduct multiple extravehicular activities to explore the boulder, and return to Earth with samples.

  20. On Control of Reaching Movements for Musculo-Skeletal Redundant Arm Model

    2009-01-01

    Full Text Available This paper focuses on a dynamic sensory-motor control mechanism of reaching movements for a musculo-skeletal redundant arm model. The formulation of a musculo-skeletal redundant arm system, which takes into account non-linear muscle properties obtained by some physiological understandings, is introduced and numerical simulations are perfomed. The non-linear properties of muscle dynamics make it possible to modulate the viscosity of the joints, and the end point of the arm converges to the desired point with a simple task-space feedback when adequate internal forces are chosen, regardless of the redundancy of the joint. Numerical simulations were performed and the effectiveness of our control scheme is discussed through these results. The results suggest that the reaching movements can be achieved using only a simple task-space feedback scheme together with the internal force effect that comes from non-linear properties of skeletal muscles without any complex mathematical computation such as an inverse dynamics or optimal trajectory derivation. In addition, the dynamic damping ellipsoid for evaluating how the internal forces can be determined is introduced. The task-space feedback is extended to the ‘virtual spring-damper hypothesis’ based on the research by Arimoto et al. (2006 to reduce the muscle output forces and heterogeneity of convergence depending on the initial state and desired position. The research suggests a new direction for studies of brain-motor control mechanism of human movements.

    Around the world, there are an estimated 300,000 to 500,000 children involved in armed conflict. Children can be abducted into a fighting force to fight or serve as sex slaves. Child soldiers have depression, anxiety, and posttraumatic stress symptoms; however, evidence is mixed because of methodologic limitations. Various mental health interventions have been tried, with promising results. Child and adolescent psychiatrists are uniquely trained in understanding and assisting youth to heal from such extraordinary experiences. A public health paradigm could include interventions that are based on a comprehensive assessment of interweaving developmental, biological, psychological, and sociocultural factors. PMID:26346388

  3. Physicists' Forced Migrations under Hitler

    2011-03-01

    When the Nazis came to power in early 1933 they initiated formal and informal measures that forced Jews and political opponents from public institutions such as universities. Some physicists retired and others went into industry, but most emigrated. International communication and contact made emigration a viable option despite the desperate economic times in the Great Depression. Another wave of emigrations followed the annexation of Austria in 1938. Individual cases as well as general patterns of migration and adaptation to new environments will be examined in this presentation. One important result of the forced migrations was that many of the physicists expelled under Hitler played important roles in strengthening physics elsewhere, often on the Allied side in World War II.

  4. Interactions between planar grafted neurofilament side-arms.

    2011-06-16

    The side-arms of neurofilaments (NFs) have been proposed to be highly disordered, leading to an entropically and electrostatically based repulsion that modulates interfilament spacing. To characterize the behavior of two interacting polymer brushes in a system of this type, we performed molecular dynamics simulations of neurofilament brushes using a four bead reduced amino acid set coarse-grained model. In these simulations, we examined components of the neurofilament brush, NF-L, NF-M, and phosphorylated NF-H (NF-HP), individually. Each protein type was grafted to planar surfaces and simulations were performed for a range of separations of two apposed grafted surfaces. The calculated force-separation curves show the force increases as the reciprocal separation as predicted for polyelectrolyte brushes at high salt. All three systems can be overlapped on a single force-separation curve, which is not expected given the variation in amino acid sequence and charges on the polymers. Examination of structural properties shows scaling behavior in the average brush height, end-to-end distance, and the density interpenetration. Some of this scaling can be understood in terms of treating the NF proteins as effective polyelectrolytes, but some cannot suggesting a distinct polyampholyte behavior. Correlations are found between oppositely charged residues in opposite brushes. However, these correlations are weak in comparison to the strong correlations within each brush. In comparison with recent experimental data that observes condensed and expanded gel states, our results suggest that the condensed state structure involves significant interdigitation of the side-arms.

    This work illustrates new tools and methods for an in vivo and direct, but non-invasive, measurement of an octopus arm mechanical properties. The active elongation (longitudinal stretch) and the pulling force capability are measured on a specimen of Octopus vulgaris in order to quantitatively characterize the parameters describing the arm mechanics, for biomimetic design purposes. The novel approach consists of observing and measuring a living octopus with minimally invasive methods, which allow the animal to move with its complete ability. All tools are conceived in order to create a collaborative interaction with the animal for the acquisition of active measures. The data analysis is executed taking into account the presence of an intrinsic error due to the mobility of the subject and the aquatic environment. Using a system of two synchronized high-speed high-resolution cameras and purpose-made instruments, the maximum elongation of an arm and its rest length (when all muscles fibres are relaxed during propulsion movement) are measured and compared to define the longitudinal stretch, with the impressive average result of 194%. With a similar setup integrated with a force sensor, the pulling force capability is measured as a function of grasp point position along the arm. The measured parameters are used as real specifications for the design of an octopus-like arm with a biomimetic approach. PMID:19965276

    2012-12-01

    Full Text Available This article presents the design of a newly developed 2DoF robotic arm with a novel statically balanced and bi-stable compliant grasper as the end effector for laparoscopic surgery application. The arm is based on internal motors actuating 2 rotational DoFs: pitch and roll. The positive stiffness of the monolithic grasper has been compensated using pre-curved straight guided beams that are preloaded collinear with the direction of actuation of the grasper. The result is a fully compliant statically balanced laparoscopic grasper. The grasper has been successfully adapted to a robotic arm. The maximum force and stiffness compensations were measured to be 94% and 97% (i.e. near zero stiffness respectively. Furthermore, the feasibility of adjusting for bi-stable behavior has been shown. This research can be a preliminary step towards the design of a statically balanced fully compliant robotic arm for laparoscopic surgery and similar areas.

  8. Arms control and disarmament: A new conceptual approach

    International Nuclear Information System (INIS)

    In the frame of the Millennium Assembly of the UN, the Secretary-General urged the global community to seize a sense of the occasion that comes from the turning of the century, to step back from today's headlines and take a broader, longer-term view of the state of the world and the challenges it poses. In partnership with the Stockholm International Peace Research Institute (SIPRI), the Department for Disarmament Affairs (DDA) is taking up precisely that challenge. This panel discussion is part of a series of events sponsored by the Department to deepen the discussion on topical disarmament and security related issues. It is also part of the constant search for a new approach, a new concept, a new paradigm or vision for disarmament and arms control since the end of the cold war, the end of the post-cold war period and the beginning of the new century. It is axiomatic that progress in disarmament is closely linked to the evolution of the security environment. Disarmament cannot be separated from the new geo-political and security configurations in Europe, new demonstrations of nuclear capability in Asia, the emergence of new conflicts that are being driven mainly by internal and ethnic strife and that are outrageous in their brutality in Europe, Asia and Africa. Today's agenda is still full and diverse in the traditional areas of disarmament, nuclear, chemical and biological disarmament as well as ballistic missile defense and proliferation and conventional disarmament including landmines. Like many organizations, research institutes, researchers and individuals in the field of security, DDA has set store on the reliability and credibility of the research and publications produced by SIPRI. As an independent international institute for research on problems for peace and conflict, disarmament and arms control founded in 1966, SIPRI's primary research has been consistently objective, timely, comprehensive and clearly presented.

    The influence of physical forces exerted by or felt by cells on cell shape, migration, and cytoskeleton arrangement is now widely acknowledged and hypothesized to occur due to modulation of cellular inside-out forces in response to changes in the external fibrous environment (outside-in). Our previous work using the non-electrospinning Spinneret-based Tunable Engineered Parameters' suspended fibers has revealed that cells are able to sense and respond to changes in fiber curvature and structural stiffness as evidenced by alterations to focal adhesion cluster lengths. Here, we present the development and application of a suspended nanonet platform for measuring C2C12 mouse myoblast forces attached to fibers of three diameters (250, 400, and 800 nm) representing a wide range of structural stiffness (3-50 nN/μm). The nanonet force microscopy platform measures cell adhesion forces in response to symmetric and asymmetric external perturbation in single and cyclic modes. We find that contractility-based, inside-out forces are evenly distributed at the edges of the cell, and that forces are dependent on fiber structural stiffness. Additionally, external perturbation in symmetric and asymmetric modes biases cell-fiber failure location without affecting the outside-in forces of cell-fiber adhesion. We then extend the platform to measure forces of (1) cell-cell junctions, (2) single cells undergoing cyclic perturbation in the presence of drugs, and (3) cancerous single-cells transitioning from a blebbing to a pseudopodial morphology.

    2012-01-01

    The quality of contracting institutions has been thought to be of second-order importance next to the impact that good property rights institutions can have on long- run growth. Using a large range of proxies for each type of institution, we find a robust $negative$ link between the quality of contracting institutions and long-run growth when we condition on property rights and a number of additional macroeconomic variables. Although the result remains something of a puzzle, we present eviden...

    In this study, a technique has been suggested to reduce a backpack load by transmitting determined loads to the children arm. The purpose of this paper is to estimate school children arm muscles while load carriage as well as to determine the safe load can be carried at wrist while walking with backpack. A mathematical model, as three DOFs model, was investigated in the sagittal plane and Lagrange multipliers method (LMM) was utilized to minimize a quadratic objective function of muscle forces. The muscle forces were minimized with three different load conditions which are termed as 0-L=0 N, 1-L=21.95 N, and 2-L=43.9 N. The investigated muscles were estimated and compared to their maximum forces throughout the load conditions. Flexor and extensor muscles were estimated and the results showed that flexor muscles were active while extensor muscles showed inactivity. The estimated muscle forces were didn't exceed their maximum forces with 0-L and 1-L conditions whereas biceps and FCR muscles exceeded their maximum forces with 2-L condition. Consequently, 1-L condition is quiet safe to be carried by hand whereas 2-L condition is not. Thus to reduce the load in the backpack the transmitted load shouldn't exceed 1-L condition.

    The ability to generate a high racket speed and a large amount of racket kinetic energy on impact is important for table tennis players. The purpose of this study was to understand how mechanical energy is generated and transferred in the racket arm during table tennis backhands. Ten male advanced right-handed table tennis players hit topspin backhands against pre-impact topspin and backspin balls. The joint kinetics at the shoulder, elbow and wrist of the racket arm was determined using inverse dynamics. A majority of the mechanical energy of the racket arm acquired during forward swing (65 and 77% against topspin and backspin, respectively) was due to energy transfer from the trunk. Energy transfer by the shoulder joint force in the vertical direction was the largest contributor to the mechanical energy of the racket arm against both spins and was greater against backspin than against topspin (34 and 28%, respectively). The shoulder joint force directed to the right, which peaked just before impact, transferred additional energy to the racket. Our results suggest that the upward thrust of the shoulder and the late timing of the axial rotation of the upper trunk are important for an effective topspin backhand.

    Full Text Available Recently, more researchers have focused on nursing-care assistant robot and placed their hope on it to solve the shortage problem of the caregivers in hospital or nursing home. In this paper, a nonprehensile two-cooperative-arm robot is considered to realize holding motion to keep a two-rigid-link object (regarded as a care-receiver stable on the robot arms. By applying Newton-Euler equations of motion, dynamic model of the object is obtained. In this model, for describing interaction behavior between object and robot arms in the normal direction, a viscoelastic model is employed to represent the normal forces. Considering existence of friction between object and robot arms, LuGre dynamic model is applied to describe the friction. Based on the obtained model, an optimal regulator is designed to control the holding motion of two-cooperative-arm robot. In order to verify the effectiveness of the proposed method, simulation results are shown.

    Full Text Available This paper presents a novel kinematic reconstruction of the human arm chain with five degrees of freedom and the estimation of the shoulder location during rehabilitation therapy assisted by end-effector robotic devices. This algorithm is based on the pseudoinverse of the Jacobian through the acceleration of the upper arm, measured using an accelerometer, and the orientation of the shoulder, estimated with a magnetic angular rate and gravity (MARG device. The results show a high accuracy in terms of arm joints and shoulder movement with respect to the real arm measured through an optoelectronic system. Furthermore, the range of motion (ROM of 50 healthy subjects is studied from two different trials, one trying to avoid shoulder movements and the second one forcing them. Moreover, the shoulder movement in the second trial is also estimated accurately. Besides the fact that the posture of the patient can be corrected during the exercise, the therapist could use the presented algorithm as an objective assessment tool. In conclusion, the joints’ estimation enables a better adjustment of the therapy, taking into account the needs of the patient, and consequently, the arm motion improves faster.

    2014-07-01

    From the Sun's location in the Galactic disk, different arm tracers (CO, H I, hot dust, etc.) have been employed to locate a tangent to each spiral arm. Using all various and different observed spiral arm tracers (as published elsewhere), we embark on a new goal, namely the statistical analysis of these published data (data mining) to statistically compute the mean location of each spiral arm tracer. We show for a typical arm cross-cut, a separation of 400 pc between the mid-arm and the dust lane (at the inner edge of the arm, toward the Galactic center). Are some arms major and others minor? Separating arms into two sets, as suggested by some, we find the same arm widths between the two sets. Our interpretation is that we live in a multiple (four-arm) spiral (logarithmic) pattern (around a pitch angle of 12°) for the stars and gas in the Milky Way, with a sizable interarm separation (around 3 kpc) at the Sun's location and the same arm width for each arm (near 400 pc from mid-arm to dust lane).

  5. Furthering critical institutionalism

    2015-03-01

    Full Text Available This special issue furthers the study of natural resource management from a critical institutional perspective. Critical institutionalism (CI is a contemporary body of thought that explores how institutions dynamically mediate relationships between people, natural resources and society. It focuses on the complexity of institutions entwined in everyday social life, their historical formation, the interplay between formal and informal, traditional and modern arrangements, and the power relations that animate them. In such perspectives a social justice lens is often used to scrutinise the outcomes of institutional processes. We argue here that critical institutional approaches have potentially much to offer commons scholarship, particularly through the explanatory power of the concept of bricolage for better understanding institutional change.  Critical institutional approaches, gathering momentum over the past 15 years or so, have excited considerable interest but the insights generated from different disciplinary perspectives remain insufficiently synthesised. Analyses emphasising complexity can be relatively illegible to policy-makers, a fact which lessens their reach. This special issue therefore aims to synthesise critical institutional ideas and so to lay the foundation for moving beyond the emergent stage to make meaningful academic and policy impact. In bringing together papers here we define and synthesise key themes of critical institutionalism, outline the concept of institutional bricolage and identity some key challenges facing this school of thought.

  6. The arms race between fishers

    Rijnsdorp, Adriaan D.; Poos, Jan Jaap; Quirijns, Floor J.; HilleRisLambers, Reinier; De Wilde, Jan W.; Den Heijer, Willem M.

    An analysis of the changes in the Dutch demersal fishing fleet since the 1950s revealed that competitive interactions among vessels and gear types within the constraints imposed by biological, economic and fisheries management factors are the dominant processes governing the dynamics of fishing fleets. Double beam trawling, introduced in the early 1960s, proved a successful fishing method to catch deep burying flatfish, in particular sole. In less than 10 years, the otter trawl fleet was replaced by a highly specialised beam trawling fleet, despite an initial doubling of the loss rate of vessels due to stability problems. Engine power, size of the beam trawl, number of tickler chains and fishing speed rapidly increased and fishing activities expanded into previously lightly fished grounds and seasons. Following the ban on flatfish trawling within the 12 nautical mile zone for vessels of more than 300 hp in 1975 and with the restriction of engine power to 2000 hp in 1987, the beam trawl fleet bifurcated. Changes in the fleet capacity were related to the economic results and showed a cyclic pattern with a period of 6-7 years. The arms race between fishers was fuelled by competitive interactions among fishers: while the catchability of the fleet more than doubled in the ten years following the introduction of the beam trawl, a decline in catchability was observed in reference beam trawlers that remained the same. Vessel performance was not only affected by the technological characteristics but also by the number and characteristics of competing vessels.

  8. Gravitoinertial force background level affects adaptation to coriolis force perturbations of reaching movements

    1998-01-01

    We evaluated the combined effects on reaching movements of the transient, movement-dependent Coriolis forces and the static centrifugal forces generated in a rotating environment. Specifically, we assessed the effects of comparable Coriolis force perturbations in different static force backgrounds. Two groups of subjects made reaching movements toward a just-extinguished visual target before rotation began, during 10 rpm counterclockwise rotation, and after rotation ceased. One group was seated on the axis of rotation, the other 2.23 m away. The resultant of gravity and centrifugal force on the hand was 1.0 g for the on-center group during 10 rpm rotation, and 1.031 g for the off-center group because of the 0.25 g centrifugal force present. For both groups, rightward Coriolis forces, approximately 0.2 g peak, were generated during voluntary arm movements. The endpoints and paths of the initial per-rotation movements were deviated rightward for both groups by comparable amounts. Within 10 subsequent reaches, the on-center group regained baseline accuracy and straight-line paths; however, even after 40 movements the off-center group had not resumed baseline endpoint accuracy. Mirror-image aftereffects occurred when rotation stopped. These findings demonstrate that manual control is disrupted by transient Coriolis force perturbations and that adaptation can occur even in the absence of visual feedback. An increase, even a small one, in background force level above normal gravity does not affect the size of the reaching errors induced by Coriolis forces nor does it affect the rate of reacquiring straight reaching paths; however, it does hinder restoration of reaching accuracy.

    1985-01-01

    From a new survey of the 2.6 mm line of CO in the southern Milky Way, 37 molecular clouds were identified along the Carina arm from l = 282 deg to 336 deg with masses generally greater than 10 to the 5th solar mass. The clouds lie approximately every 700 pc along a spiral segment that is nearly 25 kpc long and has a pitch of about 10 deg. The total mass of these clouds is 40 x 10 to the 6th solar mass, or rougly 1 x 10 to the 6th solar mass each on average. The abrupt tangent point in molecular clouds at l = 280 deg and the characteristic loop structure in the l-v diagram are unmistakable evidence of a CO spiral arm in Carina. This arm apparently connects with the northern hemisphere Sagittarius arm to form a single 10 deg spiral which extends more than two-thirds of the way around the Galaxy.

    Part-time faculty has become an important labor force in Chinese colleges and universities. The number of them has risen rapidly and its structure varies in different types of higher education institutes (HEIs), which results from integration of the social motivation and the inner motivation of schools' reform. From the institutional point of view, some problems related to the management of part-time faculty members are as follows: defects of institution design, deficiency of appointment institution mechanism, unreasonable wage treatment institution and unscientific evaluation institution. The institution construction of pat-time staff includes aspects such as qualification examination, appointment, wage, reward and punishment, evaluation, professional development and so on.

  14. The Arms Trade Treaty Opens New Possibilities at the UN

    2013-05-01

    Full Text Available On 2 April, 2013, the Arms Trade Treaty, which had been blocked for ten years in the consensus-bound Conference on Disarmament in Geneva, was put directly before the United Nations General Assembly, and was passed by a massive majority. This historic victory opens new possibilities for progress on other seemingly intractable issues. In particular, it gives hope that a Nuclear Weapons Convention might be adopted by a direct vote on the floor of the General Assembly. The adoption of the NWC, even if achieved against the bitter opposition of the nuclear weapon states, would make it clear that the world’s peoples consider the threat of an all-destroying thermonuclear war to be completely unacceptable.Other precedents can be found in the International Criminal Court and the Ottawa Land Mine Treaty, both of which were adopted despite the vehement opposition of militarily powerful states. The Arms Trade Treaty, the ICC and the Land Mine Treaty all represent great steps forward. Although they may function imperfectly because of powerful opposition, they make the question of legality clear. In time, world public opinion will force aggressor states to follow international law.

    The aim of the paper is to examine the correlation between clinical data, nutritional, respiratory and functional parameters in amyotrophic lateral sclerosis (ALS). This is a descriptive study of 111 ALS patients [91 spinal onset (GS) and 20 bulbar onset (GB)] carried on using nutritional and respiratory parameters and amyotrophic lateral sclerosis functional rating scale (ALSFRS). ALSFRS was analyzed in the main domains (D1, D2 and D3). Forced vital capacity and anthropometric measurements, there was significant association for GS and GB, and in GS there was positive correlation with midarm circumference (MAC) (r=0.30; P=0.020), midarm muscle circumference (r=0.29; P=0.026), arm muscle area (r=0.28; P=0.033) and protein-caloric malnutrition score (r=0.27; P=0.039), while for GB only with body weight (r=0.64; P=0.024). On correlation of nutritional parameters and ALSFRS for GS patients we observed that MAC and %MAC presented positive association with both issues of D1 and D2. For GB, the total score in addition to correlate positively with anthropometric parameters related to lean body mass also presented negative association with a parameter associated with body fat. In summary, it is suggested that the application of anthropometry of arm could be useful in routine monitoring of ALS patients. PMID:26788263

    2001-01-01

    DNA is of structural polymorphism, which is useful in nanoarchitecture; especially, four-arm DNA junc tions can be used to assemble nanowebs. The static four-arm DNA junctions were designed and synthesized. One-arm DNA and two-arm DNA came out simultaneously with the four-arm DNA junction's formation. A new method, termed the two-step method, was proposed and the productivity of four-arm DNA junctions was increased. A nanoweb was assembled successfully, but it showed irregularity itself. It was not the same as we expected. We consider that it is aresult from the flexibility of four-arm DNA junction.

    2010-01-01

    We investigate the relationship between spiral arms and star formation in the grand-design spirals NGC 5194 and NGC 628 and in the flocculent spiral NGC 6946. Filtered maps of near-IR (3.6 micron) emission allow us to identify "arm regions" that should correspond to regions of stellar mass density enhancements. The two grand-design spirals show a clear two-armed structure, while NGC 6946 is more complex. We examine these arm and interarm regions, looking at maps that trace recent star formation - far-ultraviolet (GALEX NGS) and 24 micron emission (Spitzer, SINGS) - and cold gas - CO (Heracles) and HI (Things). We find the star formation tracers and CO more concentrated in the spiral arms than the stellar 3.6 micron flux. If we define the spiral arms as the 25% highest pixels in the filtered 3.6 micron images, we find that the majority (60%) of star formation tracers occurs in the interarm regions; this result persists qualitatively even when considering the potential impact of finite data resolution and diffu...

  19. Force propagation and force generation in cells.

    Jonas, Oliver; Duschl, Claus

    2010-09-01

    Determining how forces are produced by and propagated through the cytoskeleton (CSK) of the cell is of great interest as dynamic processes of the CSK are intimately correlated with many molecular signaling pathways. We are presenting a novel approach for integrating measurements on cell elasticity, transcellular force propagation, and cellular force generation to obtain a comprehensive description of dynamic and mechanical properties of the CSK under force loading. This approach uses a combination of scanning force microscopy (SFM) and Total Internal Reflection Fluorescence (TIRF) microscopy. We apply well-defined loading schemes onto the apical cell membrane of fibroblasts using the SFM and simultaneously use TIRF microscopy to image the topography of the basal cell membrane. The locally distinct changes of shape and depth of the cytoskeletal imprints onto the basal membrane are interpreted as results of force propagation through the cytoplasm. This observation provides evidence for the tensegrity model and demonstrates the usefulness of our approach that does not depend on potentially disturbing marker compounds. We confirm that the actin network greatly determines cell stiffness and represents the substrate that mediates force transduction through the cytoplasm of the cell. The latter is an essential feature of tensegrity. Most importantly, our new finding that, both intact actin and microtubule networks are required for enabling the cell to produce work, can only be understood within the framework of the tensegrity model. We also provide, for the first time, a direct measurement of the cell's mechanical power output under compression at two femtowatts. PMID:20607861

Numerical simulations were performed using a Lattice-Boltzmann model for moderate Reynolds numbers. The computation of the hydrodynamic force on the foil is related to the the wake structure. In particular, when the foil's centre of mass is fixed in space, numerical results suggest a relation between drag coefficient behaviour and the flapping frequency which determines the transition from the von K\\'arm\\'an (vKm) to the inverted von K\\'arm\\'an wake. Beyond the inverted vKm transition the foil was released. Upstream swimming was observed at high enough flapping frequencies. Computed hydrodynamic forces suggest the propulsion mechanism for the swimming foil.

  2. Malaysia and forced migration

    Full Text Available This paper analyzes the phenomenon of “forced migration” in Malaysia. It examines the nature of forced migration, the challenges faced by Malaysia, the policy responses and their impact on the country and upon the forced migrants. It considers forced migration as an event hosting multifaceted issues related and relevant to forced migrants and suggests that Malaysia has been preoccupied with the issue of forced migration movements. This is largely seen in various responses invoked from Malaysia due to “south-south forced migration movements.” These responses are, however, inadequate in terms of commitment to the international refugee regime. While Malaysia did respond to economic and migration challenges, the paper asserts that such efforts are futile if she ignores issues critical to forced migrants.

Not unlike the disturbed client seeking psychotherapy, the problems the institution has with the introduction of computers are symptoms of deeper problems.

    2009-06-01

    We have extensively used arm cycling to study the neural control of rhythmic movements such as arm swing during walking. Recently rhythmic movement of the arms has also been shown to enhance and shape muscle activity in the legs. However, restricted information is available concerning the conditions necessary to maximally alter lumbar spinal cord excitability. Knowledge on the neuromechanics of a task can assist in the determination of the type, level, and timing of neural signals, yet arm swing during walking and arm cycling have not received a detailed neuromechanical comparison. The purpose of this research was to provide a combined neural and mechanical measurement approach that could be used to assist in the determination of the necessary and sufficient conditions for arm movement to assist in lower limb rehabilitation after stroke and spinal cord injury. Subjects performed three rhythmic arm movement tasks: (1) cycling (cycle); (2) swinging while standing (swing); and (3) swinging while treadmill walking (walk). We hypothesized that any difference in neural control between tasks (i.e., pattern of muscle activity) would reflect changes in the mechanical constraints unique to each task. Three-dimensional kinematics were collected simultaneously with force measurement at the hand and electromyography from the arms and trunk. All data were appropriately segmented to allow a comparison between and across conditions and were normalized and averaged to 100% movement cycle based on shoulder excursion. Separate mathematical principal components analysis of kinematic and neural variables was performed to determine common task features and muscle synergies. The results highlight important neural and mechanical features that distinguish differences between tasks. For example, there are considerable differences in the anatomical positions of the arms during each task, which relate to the moments experienced about the elbow and shoulder. Also, there are differences between

  13. Dual Arm Work Module Development and Appplications

    Energy Technology Data Exchange (ETDEWEB)

    Noakes, M.W.

    1999-04-25

    The dual arm work module (DAWM) was developed at Oak Ridge National Laboratory (ORNL) by the Robotics Technology Development Program (RTDP) as a development test bed to study issues related to dual arm manipulation, including platform cotilguration, controls, automation, operations, and tooling. The original platform was based on two Schilling Titan II manipulators mounted to a 5-degree-of- freedom (DOF) base fabricated by RedZone Robotics, Inc. The 5-DOF articulation provided a center torso rotation, linear actuation to change the separation between the arms, and arm base rotation joints to provide "elbows up," elbows down," or "elbows out" orientation. A series of tests were conducted on operations, tooling, and task space scene analysis (TSSA)-driven robotics for overhead transporter- mounted and crane hook-deployed scenarios. A concept was developed for DAWM deployment from a large remote work vehicle, but the project was redirected to support dismantlement of the Chicago Pile #5 (CP-5) reactor at Argonne National Laboratory in fiscal year (FY) 1997. Support of CP-5 required a change in focus of the dual arm technology from that of a development test bed to a system focussed for a specific end user. ORNL teamed with the Idaho National Environmental ,Engineering Laboratory, Sandia National Laboratory, and the Savannah River Technology Center to deliver a crane-deployed derivative of the DAWM, designated the dual arm work platform (DAWP). RTDP staff supported DAWP at CP-5 for one FY; Argonne staff continued operation through to dismantlement of the reactor internals. Lessons learned from this interaction were extensive. Beginning in FY 1999, dual arm development activities are again being pursued in the context of those lessons learned. This paper describes the progression of philosophy of the DAWM from initial test bed to lessons learned through interaction at CP-5 and to the present investigation of telerobotic assist of teleoperation and TSSA- driven robotics.

  14. The drag force during the transient regime

    CERN Document Server

    Souza, P V S; de Oliveira, P M C

    2015-01-01

    In this paper, we analyze the drag force acting on a cylinder in a wind tunnel. The inspiration comes from an experimental result: a small, light ball falls on air; its speed increases, reaches a maximum, decreases and finally stabilizes. This surprising breaking behavior is due to the gradual formation of the so-called von K\\'arm\\'an street of air vortices behind the ball: while it is not completely formed, the transient drag force is smaller than the known steady state value and the ball can reach speeds higher than its final value. To show it, we treat the similar problem of a cylinder inside a wind tunnel suddenly switched on, by solving the Navier-Stokes dynamic equation. We use a finite difference method with successive relaxations on a grid. We also treat the case of a rotating cylinder, leading to the Magnus force. The novelty is the method we use to calculate these forces, which avoids the traditional surface integration of velocity gradients; the latter demands a very precise determination of the ve...

    1993-03-01

    EXOS has developed two state of the art prototype master controllers for controlling robot hands and manipulators under the Small Business Innovation Research (SBIR) program with NASA. One such device is a two degree-of-freedom Sensing and Force Reflecting Exoskeleton (SAFiRE) worn on the operator's hand. The device measures the movement of the index finger and reflects the interaction forces between the slave robot and the environment to the human finger. The second device is a position sensing Exoskeleton ArmMaster (EAM) worn by a human operator. The device simultaneously tracks the motions of the operator's three DOF shoulder and two DOF elbow. Both of these devices are currently used to control robots at NASA. We are currently developing a full fingered SAFiRE and a position sensing and force reflecting EAM under two second phase SBIR grants with NASA. This paper will include discussions of: (1) the design of the current prototypes, (2) kinematics of the EAM and force control of the SAFiRE, (3) design issues that must be addressed in developing more advanced versions, and (4) our progress to date in addressing these issues.

    The present invention is a low friction, low inertia, six-axis force feedback input device comprising an arm with double-jointed, tendon-driven revolute joints, a decoupled tendon-driven wrist, and a base with encoders and motors. The input device functions as a master robot manipulator of a microsurgical teleoperated robot system including a slave robot manipulator coupled to an amplifier chassis, which is coupled to a control chassis, which is coupled to a workstation with a graphical user interface. The amplifier chassis is coupled to the motors of the master robot manipulator and the control chassis is coupled to the encoders of the master robot manipulator. A force feedback can be applied to the input device and can be generated from the slave robot to enable a user to operate the slave robot via the input device without physically viewing the slave robot. Also, the force feedback can be generated from the workstation to represent fictitious forces to constrain the input device's control of the slave robot to be within imaginary predetermined boundaries.

    We use a global climate model to compare the effectiveness of many climate forcing agents for producing climate change. We find a substantial range in the "efficacy" of different forcings, where the efficacy is the global temperature response per unit forcing relative to the response to CO2 forcing. Anthropogenic CH4 has efficacy ˜110%, which increases to ˜145% when its indirect effects on stratospheric H2O and tropospheric O3 are included, yielding an effective climate forcing of ˜0.8 W/m2 for the period 1750-2000 and making CH4 the largest anthropogenic climate forcing other than CO2. Black carbon (BC) aerosols from biomass burning have a calculated efficacy ˜58%, while fossil fuel BC has an efficacy ˜78%. Accounting for forcing efficacies and for indirect effects via snow albedo and cloud changes, we find that fossil fuel soot, defined as BC + OC (organic carbon), has a net positive forcing while biomass burning BC + OC has a negative forcing. We show that replacement of the traditional instantaneous and adjusted forcings, Fi and Fa, with an easily computed alternative, Fs, yields a better predictor of climate change, i.e., its efficacies are closer to unity. Fs is inferred from flux and temperature changes in a fixed-ocean model run. There is remarkable congruence in the spatial distribution of climate change, normalized to the same forcing Fs, for most climate forcing agents, suggesting that the global forcing has more relevance to regional climate change than may have been anticipated. Increasing greenhouse gases intensify the Hadley circulation in our model, increasing rainfall in the Intertropical Convergence Zone (ITCZ), Eastern United States, and East Asia, while intensifying dry conditions in the subtropics including the Southwest United States, the Mediterranean region, the Middle East, and an expanding Sahel. These features survive in model simulations that use all estimated forcings for the period 1880-2000. Responses to localized forcings, such

    Full Text Available Although it is common for armed groups to splinter (or “fragment” during contexts of multi-party civil war, current guidance on Disarmament, Demobilization, and Reintegration (DDR does not address the challenges that arise when recalcitrant fighters, unwilling to report to DDR, break ranks and form new armed groups. This Practice Note addresses this issue, drawing lessons from the multi-party context of the DRC and from the experiences of former members of three armed groups: the Rally for Congolese Democracy-Goma (RCD-Goma, the National Congress for the Defense of the People (CNDP, and the DRC national army (FARDC. While the findings indicate that the fragmentation of armed groups may encourage desertion and subsequent participation in DDR, they also show that active armed groups may monitor DDR programs and track those who demobilize. Remobilization may follow, either as active armed groups target ex-combatants for forced re-recruitment or as ex-combatants remobilize in armed groups of their own choice. Given these dynamics, practitioners in settings of partial peace may find it useful to consider non-traditional methods of DDR such as the use of mobile patrols and mobile disarmament units. The temporary relocation of ex-combatants to safe areas free from armed groups, or to protected transitional assistance camps, may also help to minimize remobilization during the reintegration phase.

  20. A comparison of the moment arms of pelvic limb muscles in horses bred for acceleration (Quarter Horse) and endurance (Arab).

    Selective breeding for performance has resulted in distinct breeds of horse, such as the Quarter Horse (bred for acceleration) and the Arab (bred for endurance). Rapid acceleration, seen during Quarter Horse racing, requires fast powerful muscular contraction and the generation of large joint torques, particularly by the hind limb muscles. This study compared hind limb moment arm lengths in the Quarter Horse and Arab. We hypothesized that Quarter Horse hind limb extensor muscles would have longer moment arms when compared to the Arab, conferring a greater potential for torque generation at the hip, stifle and tarsus during limb extension. Six Quarter Horse and six Arab hind limbs were dissected to determine muscle moment arm lengths for the following muscles: gluteus medius, biceps femoris, semitendinosus, vastus lateralis, gastrocnemius (medialis and lateralis) and tibialis cranialis. The moment arms of biceps femoris (acting at the hip) and gastrocnemius lateralis (acting at the stifle) were significantly longer in the Quarter Horse, although the length of the remaining muscle moment arms were similar in both breeds of horse. All the Quarter Horse muscles were capable of generating greater muscle moments owing to their greater physiological cross-sectional area (PCSA) and therefore greater isometric force potential, which suggests that PCSA is a better determinant of muscle torque than moment arm length in these two breeds of horse. With the exception of gastrocnemius and tibialis cranialis, the observed muscle fascicle length to moment arm ratio (MFL : MA ratio) was greater for the Arab horse muscles. It appears that the Arab muscles have the potential to operate at slower velocities of contraction and hence generate greater force outputs when compared to the Quarter Horse muscles working over a similar range of joint motion; this would indicate that Arab hind limb muscles are optimized to function at maximum economy rather than maximum power output.

  2. Understanding and Improving CRM and GCM Simulations of Cloud Systems with ARM Observations

    The works supported by this ASR project lay the solid foundation for improving the parameterization of convection and clouds in the NCAR CCSM and the climate simulations. We have made a significant use of CRM simulations and ARM observations to produce thermodynamically and dynamically consistent multi-year cloud and radiative properties; improve the GCM simulations of convection, clouds and radiative heating rate and fluxes using the ARM observations and CRM simulations; and understand the seasonal and annual variation of cloud systems and their impacts on climate mean state and variability. We conducted multi-year simulations over the ARM SGP site using the CRM with multi-year ARM forcing data. The statistics of cloud and radiative properties from the long-term CRM simulations were compared and validated with the ARM measurements and value added products (VAP). We evaluated the multi-year climate simulations produced by the GCM with the modified convection scheme. We used multi-year ARM observations and CRM simulations to validate and further improve the trigger condition and revised closure assumption in NCAR GCM simulations that demonstrate the improvement of climate mean state and variability. We combined the improved convection scheme with the mosaic treatment of subgrid cloud distributions in the radiation scheme of the GCM. The mosaic treatment of cloud distributions has been implemented in the GCM with the original convection scheme and enables the use of more realistic cloud amounts as well as cloud water contents in producing net radiative fluxes closer to observations. A physics-based latent heat (LH) retrieval algorithm was developed by parameterizing the physical linkages of observed hydrometeor profiles of cloud and precipitation to the major processes related to the phase change of atmospheric water.

    An exoskeleton force feedback dataglove is developed, which uses the pneumatic artificial muscles as actuators. On the basis of the simplified hand model, the motion equation is deduced according to the theory of Denavit-Hartenberg. The model of the equivalent contact forces exerted by the object on the finger is proposed. By the principle of virtual work, the static equilibrium of finger is established. The force Jacobian matrix of finger is calculated, and then the joint torques of the finger when grasping objects are obtained. The theory and structure of the force feedback datagolve are introduced. Based on the theory of motion stabilization of four-bar linkage, the flexion angles of joints are measured. The torques on finger joints caused by the output forces of pneumatic artificial muscles are calculated. The output forces of pneumatic artificial muscle, whose values are controlled by its inner pressure, can be calculated by the joint torques ofthe finger when grasping objects. The arms of force, driving torques and the needed output forces of pneumatic muscle are calculated for each joint of the index finger. The criterion of output force of pneumatic muscle is given.

    2015-04-01

    The Milky Way is a spiral galaxy with (or without) a bar-like central structure. There is evidence that the distribution of suspected cosmic ray sources, such as supernova remnants, are associated with the spiral arm structure of galaxies. It is yet not clearly understood what effect such a cosmic ray source distribution has on the particle transport in our Galaxy. We investigate and measure how the propagation of Galactic cosmic rays is affected by a cosmic ray source distribution associated with spiral arm structures. We use the PICARD code to perform high-resolution 3D simulations of electrons and protons in galactic propagation scenarios that include four-arm and two-arm logarithmic spiral cosmic ray source distributions with and without a central bar structure as well as the spiral arm configuration of the NE2001 model for the distribution of free electrons in the Milky Way. Results of these simulation are compared to an axisymmetric radial source distribution. Also, effects on the cosmic ray flux and spectra due to different positions of the Earth relative to the spiral structure are studied. We find that high energy electrons are strongly confined to their sources and the obtained spectra largely depend on the Earth's position relative to the spiral arms. Similar finding have been obtained for low energy protons and electrons albeit at smaller magnitude. We find that even fractional contributions of a spiral arm component to the total cosmic ray source distribution influences the spectra on the Earth. This is apparent when compared to an axisymmetric radial source distribution as well as with respect to the Earth's position relative to the spiral arm structure. We demonstrate that the presence of a Galactic bar manifests itself as an overall excess of low energy electrons at the Earth. Using a spiral arm geometry as a cosmic ray source distributions offers a genuine new quality of modeling and is used to explain features in cosmic ray spectra at the Earth

    Chemistry is determined by the electrostatic forces acting within a collection of nuclei and electrons. The attraction of the nuclei for the electrons is the only attractive force in a molecule and is the force responsible for the bonding between atoms. This is the attractive force acting on the electrons in the Ehrenfest force and on the nuclei in the Feynman force, one that is countered by the repulsion between the electrons in the former and by the repulsion between the nuclei in the latter. The virial theorem relates these forces to the energy changes resulting from interactions between atoms. All bonding, as signified by the presence of a bond path, has a common origin in terms of the mechanics determined by the Ehrenfest, Feynman and virial theorems. This paper is concerned in particular with the mechanics of interaction encountered in what are classically described as 'nonbonded interactions'--are atoms that 'touch' bonded or repelling one another?

    We present Heisenberg's equation of motion for the radial variable of a free non-relativistic particle in D dimensions. The resulting radial force consists of three contributions: (i) the quantum fictitious force which is either attractive or repulsive depending on the number of dimensions, (ii) a singular quantum force located at the origin, and (iii) the centrifugal force associated with non-vanishing angular momentum. Moreover, we use Heisenberg's uncertainty relation to introduce a lower bound for the kinetic energy of an ensemble of neutral particles. This bound is quadratic in the number of atoms and can be traced back to the repulsive quantum fictitious potential. All three forces arise for a free particle: ''Force without force''. (orig.)

    the stable and planned and predominantly national models of economic organization supported by the Keynesian state, which dominated in the 30 years after 1945, to the uncertain and high-risk environment of the current period in which globalization has opened up the possibility of new forms of firms...... and institutions. In this paper, we emphasize that in the current context of globalization, firms and actors within firms are continuously developing the way in which they organize work and employment to produce goods and services that are competitive in global markets. The paper argues that new market conditions...... lead firms to constant experimentation in work organization as they seek to position themselves within systems of production and innovation that are global in nature. This creates a pressure for institutional change to facilitate the process of firm-level experimentation; it also tends to create...

    The emergence of the market as a regulatory tool for the public sector and the promotion of competition among institutions are based upon the idea that they promote institutions' responsiveness to society and a more efficient use of public funds. However, autonomous institutions forced to compete under market-like conditions may follow strategies…

    This document describes a new Atmospheric Radiation Measurement (ARM) data set, the ARM Cloud Retrieval Ensemble Data Set (ACRED), which is created by assembling nine existing ground-based cloud retrievals of ARM measurements from different cloud retrieval algorithms. The current version of ACRED includes an hourly average of nine ground-based retrievals with vertical resolution of 45 m for 512 layers. The techniques used for the nine cloud retrievals are briefly described in this document. This document also outlines the ACRED data availability, variables, and the nine retrieval products. Technical details about the generation of ACRED, such as the methods used for time average and vertical re-grid, are also provided.

    Using the decades of experience of developing concepts and technologies for verifying bilateral and multilateral arms control agreements, a broad conceptual systems approach is being developed that takes into account varying levels of information and risk. The IAEA has already demonstrated the applicability of a systems approach by implementing safeguards at the State level, with acquisition path analysis as the key element. In order to test whether such an approach could also be implemented for arms control verification, an exercise was conducted in November 2014 at the JRC ITU Ispra. Based on the scenario of a hypothetical treaty between two model nuclear weapons states aimed at capping their nuclear arsenals at existing levels, the goal of this exercise was to explore how to use acquisition path analysis in an arms control context. Our contribution will present the scenario, objectives and results of this exercise, and attempt to define future workshops aimed at further developing verification measures that will deter or detect treaty violations.

    In order to improve the link between an operator and its machine, some human oriented communication systems are now using natural languages like speech or gesture. The goal of this paper is to present a gesture recognition system based on the fusion of measurements issued from different kind of sources. It is necessary to have some sensors that are able to capture at least the position and the orientation of the hand such as Dataglove and a video camera. Datagloge gives a measure of the hand posture and a video camera gives a measure of the general arm gesture which represents the physical and spatial properties of the gesture, and based on the 2D skeleton representation of the arm. The measurements used are partially complementary and partially redundant. The application is distributed on intelligent cooperating sensors. The paper presents the measurement of the hand and the arm gestures, the fusion processes, and the implementation solution.

    Interarm star formation contributes significantly to a galaxy's star formation budget, and provides an opportunity to study stellar birthplaces unperturbed by spiral arm dynamics. Using optical integral field spectroscopy of the nearby galaxy NGC 628 with VLT/MUSE, we identify 391 HII regions at 35pc resolution over 12 kpc^2. Using tracers sensitive to the underlying gravitational potential, we associate HII regions with either arm (271) or interarm (120) environments. We find that most HII region physical properties (luminosity, size, metallicity, ionization parameter) are independent of environment. We calculate the fraction of Halpha luminosity due to the diffuse ionized gas (DIG) background contaminating each HII region, and find the DIG surface brightness to be higher within HII regions compared to the surroundings, and slightly higher within arm HII regions. Use of the temperature sensitive [SII]/Halpha line ratio map instead of the Halpha surface brightness to identify HII region boundaries does not ch...
