Abstract This essay is addressed to discrepancies between musical and political time. It uses the death of Hugh Masekela to consider the changing pattern of intergenerational relationships and the place of music within local and transnational freedom movements. The impact of technological change on the mediation of political solidarity is then examined through two principal examples: the elaboration of generic racial identity and the weaponization of culture and information by the alt-right and its fellow travelers.

Streszczenie:

Minimally invasive surgery (MIS), even with its shortcomings, has had a far reaching impact in the field of surgery. During MIS procedures, as the surgeon's hands are remote from the site of the surgery, they do not have a feel of the tissue being manipulated and the forces that should be applied to manipulate the tissue. Studies are being conducted to provide tactile and force feedback of the tissues being manipulated to the surgeon. However, the surgeons are trained in conventional surgery and are familiar with the forces that they apply on the conventional surgical tools. Therefore, before such studies are conducted, there is a need for quantitative comparison of conventional and laparoscopic tools. The purpose of the present investigation was to determine if the forces applied on the conventional surgical forceps are the same as those applied on the laparoscopic forceps during the same procedures. The results of the study showed that the handle and tip forces in laparoscopic forceps were significantly different from that of the conventional surgical forceps (p ≤0.005). The results also showed that the mean power of the surface EMG measured from flexor pollicis brevis (flexor of the thumb) and the extensor pollicis brevis (extensor of the proximal thumb) while manipulating laparoscopic forceps were significantly different from that measured while manipulating conventional surgical forceps for the same procedure (p ≤ 0.005).

Streszczenie:

There exists an opinion that the modern numerical methods allow to solve practically any problem in mechanics. But it should be noted that both analytical and experimental methods, as before, are urgent, and exactly a complex of methods develops the mechanics of deformable rigid bodies. The statement of a problem in displacements for some possible cases of equivalent substitution of loads allows to formulate necessary and sufficient conditions of existence of an analogy presenting the effect of a forced deformation in the form of the sum of surface and volume forces, the effect of volume forces in the form of the sum of surface forces and forced deformations, the effect of surface forces in the form of the sum of forced deformations and volume forces. The substitution of volume forces for surface loads and forced deformations allows to extend the use of experimental methods and often to solve through an experimental-and theoretical approach the problems, which cannot be solved through other methods. The obtained results are a considerable step in the development of one of the approaches combining experimental, analytical and numerical methods of solution of linear problems in mechanics of deformable rigid bodies.

Acknowledgements 2556. References 255While the intermolecular forces between biological molecules are no different from those that arise between any other types of molecules, a ‘biological interaction’ is usually very different from a simple chemical reaction or physical change of a system. This is due in part to the higher complexity of biological macromolecules and systems that typically exhibit a hierarchy of self-assembling structures ranging in size from proteins to membranes and cells, to tissues and organs, and finally to whole organisms. Moreover, interactions do not occur in a linear, stepwise fashion, but involve competing interactions, branching pathways, feedback loops, and regulatory mechanisms.

Compression (or crushing) is used to induce nerve injury in test rats to study nerve degeneration and regeneration. The compression forces could be applied using a variety of techniques developed by several investigators. The lack of precise control of the applied compression may be the source of significant variations among observations. In this study, a Mosquito and dressing forceps were used. The Mosquito forceps was calibrated to determine the tip load corresponding to the clamping position. The dressing forceps was modified, instrumented with strain gauges and calibrated to directly measure the force applied at its tip. These two forceps were used to induce known and controlled nerve compression in 75 male Wistar rats (280–300g). The applied forces were of the order of 40N and 20N, for the Mosquito and dressing forceps, respectively.

Streszczenie:

Inherent in the construction of many experimental apparatus designed to measure the hydro/aerodynamic forces of rotating machinery are features that contribute undesirable parasitic forces to the measured or test forces. Typically, these parasitic forces are due to seals, drive couplings, and hydraulic and/or inertial unbalance. To obtain accurate and sensitive measurement of the hydro/aerodynamic forces in these situations, it is necessary to subtract the parasitic forces from the test forces. In general, both the test forces and the parasitic forces will be dependent on the system operating conditions including the specific motion of the rotor. Therefore, to properly remove the parasitic forces the vibration orbits and operating conditions must be the same in tests for determining the hydro/aerodynamic forces and tests for determining the parasitic forces. This, in turn, necessitates a means by which the test rotor’s motion can be accurately controlled to an arbitrarily defined trajectory. Here in, an interrupt-driven multiple harmonic open-loop controller was developed and implemented on a laboratory centrifugal pump rotor supported in magnetic bearings (active load cells) for this purpose. This allowed the simultaneous control of subharmonic, synchronous, and superharmonic rotor vibration frequencies with each frequency independently forced to some user defined orbital path. The open-loop controller was implemented on a standard PC using commercially available analog input and output cards. All analog input and output functions, transformation of the position signals from the time domain to the frequency domain, and transformation of the open-loop control signals from the frequency domain to the time domain were performed in an interrupt service routine. Rotor vibration was attenuated to the noise floor, vibration amplitude ≈0.2 μm, or forced to a user specified orbital trajectory. Between the whirl frequencies of 14 and 2 times running speed, the orbit semi-major and semi-minor axis magnitudes were controlled to within 0.5% of the requested axis magnitudes. The ellipse angles and amplitude phase angles of the imposed orbits were within 0.3 deg and 1.0 deg, respectively, of their requested counterparts.

Streszczenie:

A new calibration method of frictional forces in atomic force microscopy (AFM) is suggested. An angle conversion factor is defined using the relationship between torsional angle and frictional signal. When the factor is measured, the slopes of the torsional angle and the frictional signal as a function of the normal force are used to eliminate the effect of the adhesive force. Moment balance equations on the flat surface and the top edge of a commercial step grating are used to obtain the angle conversion factor. After the factor is obtained from an AFM system, it can be applied to all cantilevers without additional experiments.

Streszczenie:

Governments often supplement the regular military with paramilitaries and progovernment militias (PGMs). However, it is unclear what determines states’ selection of these auxiliary forces, and our understanding of how auxiliary force structures develop remains limited. The crucial difference between the two auxiliary types is their embeddedness in official structures. Paramilitaries are organized under the government to support/replace the regular military, whereas PGMs exist outside the state apparatus. Within a principal–agent framework, we argue that a state’s investment in a particular auxiliary force structure is shaped by available resources and capacity, accountability/deniability, and domestic threats. Our results based on quantitative analysis from 1981 to 2007 find that (a) state capacity is crucial for sustaining paramilitaries, but not PGMs; (b) PGMs, unlike paramilitaries, are more common in states involved in civil conflict; and (c) although both paramilitaries and PGMs are associated with regime instability, there is no significant difference between them in that context.

Streszczenie:

The traditional approach of using free vibration modes in the assumed mode method often leads to an extremely slow convergence rate, especially when discete interactive forces are involved. By introducing a number of forced modes, significant improvements can be achieved. These forced modes are intrinsic to the structure and the spatial distribution of forces. The motion of the structure can be described exactly by these forced modes and a few free vibration modes provided that certain conditions are satisfied. The forced modes can be viewed as an extension of static modes. The development of a forced mode formulation is outlined and a numerical example is presented.

Introduction. In order to achieve a minimal trauma to the inner ear structures during array insertion, it would be suitable to control insertion forces. The aim of this work was to compare the insertion forces of an array insertion into anatomical specimens with three different insertion techniques: with forceps, with a commercial tool, and with a motorized tool.Materials and Methods. Temporal bones have been mounted on a 6-axis force sensor to record insertion forces. Each temporal bone has been inserted, with a lateral wall electrode array, in random order, with each of the 3 techniques.Results. Forceps manual and commercial tool insertions generated multiple jerks during whole length insertion related to fits and starts. On the contrary, insertion force with the motorized tool only rose at the end of the insertion. Overall force momentum was 1.16 ± 0.505 N (mean ± SD,n=10), 1.337 ± 0.408 N (n=8), and 1.573 ± 0.764 N (n=8) for manual insertion with forceps and commercial and motorized tools, respectively.Conclusion. Considering force momentum, no difference between the three techniques was observed. Nevertheless, a more predictable force profile could be observed with the motorized tool with a smoother rise of insertion forces.

Designing mechanical systems which are submitted to vibration requires calculation methods which are very different to those used in other disciplines because, when this occurs, the magnitude of the forces becomes secondary and the frequency with which the force is repeated becomes the most important aspect. It must be taken care of, given that smaller periodic forces can prompt disasters than greater static forces. The article presents a representative problem regarding systems having forced vibration, the mathematical treatment of differential equations from an electrical and mechanical viewpoint, an electrical analogy, numerical modeling of circuits using ANSYS finite element software, analysis and comparison of numerical modeling results compared to test values, the post-processing of results and conclusions regarding electrical analogy methodology when analysing forced vibration systems.

Background. To assess the peeling forces exerted by different calibers of microsurgical forceps on an experimental model of epiretinal membrane.Methods. A model of epiretinal membrane was constructed using thin cellulose paper and heptanes-isopropyl alcohol 1% mixture. The model was mounted on a force censoring device. Subsequently, flaps were created with three different microsurgical forceps of different calibers. We recorded the number of attempts, the duration of the event, and the pushing and the pulling forces during the peeling. The results were compared by a one-way ANOVA and a Fisher unprotected least significant difference test with an alpha value of 0.05 for statistically significance.Results. There was a statistical significant difference on the pulling and pushing forces between the 25 gauge (13.79 mN; −13.27 mN) and the 23 (6.63 mN; −5.76 mN) and 20 (5.02 mN; −5.30 mN) gauge, being greater in the first (P<0.001). There were no differences in the duration of all events, meaning that all the forces were measured within the same period of time.Conclusions. The 25 gauge microsurgical forceps exerted the greatest mechanical stress over our simulated epiretinal membrane model and required more attempts to create a surgical suitable flap. The clinical implication of this finding is still to be determined.

Abstract The longlasting process of transformation of the armed forces, as well as the reduction of staff resulted in the loss of certain capabilities. In times of transformation, the different structures of the Bulgarian Armed Forces, led by the desire to preserve their most important capabilities, namely the combat ones, are forced to lay off mainly parts of their maintenance and support units. In order to compensate for these lost capabilities, the armed forces resorted to the use of outsourcing services for the repair and maintenance of armament and military equipment.This article studies and analyses the use of outsourcing services for the maintenance and repair of equipment and armament available in the structures of the Bulgarian Armed Forces.

Streszczenie:

Nonlinear aerodynamic forces on the flat plate subjected to a forced torsional oscillation of asymptotically varying amplitude at high reduced velocities are investigated by using computational fluid dynamics method integrated with continuous wavelet transform method. The domain decomposition algorithm is used in the numerical simulation to accommodate large amplitude oscillation of plate. The continuous wavelet transform is used to extract the instantaneous amplitude and phase features from the computed time histories of the asymptotically aerodynamic forces on the plate. The results show that the computed characteristics of the aerodynamic forces are in good agreement with the available experimental data. The nonlinear features of the aerodynamic forces are well revealed by the present method.
