Повний текст джерелаThe general context, in which this thesis is located, is the situation of the productive restructuring that has introduced innovative technology and new forms of management and mobilization of the workforce as part of a new balance of power between capital and labour from the structural crisis of seventies. Specifically, the research subject is the tension between efficiency and hierarchical control through increasing automation. To understand this tension we have studied with ethnographic methodology, organization and ways of controlling the labour force of two companies working oil in Bolivia. Based on the results of our research, we found that the trend of the technical division of labour has taken a contradictory process that illustrates the tension between the demands of technical efficiency in automation, such as the integration of work and relations of domination and hierarchy that are essential within the capitalist enterprise. The process, one side encourages the integration of work and elsewhere implements constraints to integration. Consequently, if we introduce a comprehensive approach to the process and, in the same direction, we consider not only the form but the content of social relations of production, abut and adversarial process that while looking for the exploitation and subordination of the labour force, opens spaces for new sources of productivity from the involvement of workers

Tremblay, Stéphanie. "Force field adaptation in speech production." Thesis, McGill University, 2006. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=103014.
Повний текст джерелаThe first study aimed at providing a test of whether somatosensory feedback plays a role in speech production beyond the language acquisition period in early childhood. In order to achieve this goal, we designed a pattern of forces that affects jaw movements during speech production, but at the same time has no measurable acoustic effect. We found that subjects compensated for such a distortion in speech movement trajectories, even though it had no impact on the sounds. In contrast, no adaptation was observed in matched non-speech jaw movements, indicating that this was not an inevitable consequence of exposing the orofacial apparatus to this pattern of forces. This is the first demonstration that somatosensory information on its own drives the achievement of articulator positions in speech.
In study one, it was observed that subjects only adapted to the loads in the opening phase of the jaw movement. In order to elucidate this somewhat unexpected finding, we carried out experiments in which we manipulated the linguistic content of the training utterance. We found that subjects compensated for the perturbations only in portions of the movement that contained a vowel-to-vowel transition. It was suggested that the required kinematic precision during a transition between two vocal tract shapes associated with vowels is higher than during transitions between a consonant and a vowel. It also points to the speech-like nature of the observed adaptation.
The third study aimed at investigating the extent to which speech motor learning generalizes across acoustic contexts. We trained subjects to produce utterances while exposed to a velocity dependent force field. After learning, the subjects were tested with new utterances, matched on dynamics to the ones used in training. Note that even if the acoustic contents of the test and the training utterances were different, the loads had a similar effect on both speech movements. We showed that learning did not transfer to the test utterances; therefore adaptation was restricted to the specific training context. These results point to the specificity of speech motor learning.

Повний текст джерелаKollimada, Aiyappa Somanna. "Study of the factors regulating traction force production by cells." Thesis, Université Grenoble Alpes, 2020. http://www.theses.fr/2020GRALY050.
Повний текст джерелаMechanical forces are involved in many physiological processes including morphogenesis, migration, division and differentiation. All these events involve a tight regulation of both the magnitude and spatial distribution of the contractile forces at the cell and tissue-level. Although we know that at the molecular level, the regulation of force production and transmission relies on the complex interplay between a well-conserved set of proteins of the cytoskeleton, we still do not have a comprehensive understanding of the mechanisms supporting force generation at the entire cell level. In addition, the magnitude of the traction forces exerted by cells on their underlying extracellular matrix in culture and as such the cell to cell variation of theses forces remain difficult to predict, largely because of the difficulty to characterize precisely how molecular components forming the actomyosin and adhesion networks, individually or via their specific interplay, are related to the force magnitude exerted by these cells. In this context, the aim of my PhD project was to investigate how key biological parameters are precisely related to force generation and regulation process.The first part of my study thereby focused on looking into the effect of the progression of the cell cycle on cell to cell heterogeneity in traction forces. I demonstrated that although the cell cycle status of the cells had a major impact on the magnitude of forces exerted by cells, it was not impacting the overall cell to cell variability in the traction force exerted. I also examined next the possibility that some internal/subcellular contractile efforts could be dissipated instead of being transmitted to cell anchorages by looking at the interplay between actin dynamics and traction forces. The analysis of actin turnover in stress fibers showed that although variations in strain energies were associated to variations in actin dynamics, they were not significant enough to explain the large cell to cell heterogeneities measured in traction force. Finally, I conducted a study dedicated to the characterization of the biochemical composition of the actomyosin network and adhesion pattern of cells in relationship with the force generated and transmitted by cells. To that end, I implemented the standard TFM assay in order to introduce an intermediate labeling step allowing for simultaneous measurement of traction forces and intracellular protein contents. This assay was then used to characterize the content of molecules of the actomyosin cytoskeleton and of the adhesions, either alone or in combination, and force. This work first demonstrated that the vinculin content measured at the level of the entire cell and the area of the focal adhesions, represented good predictors of force. I then showed that actin and myosin displayed broader deviations in their linear relationship to the strain energies, and thus appeared as less reliable predictors of force. Instead, my data suggested that their relative cellular amount plays a key role in setting the magnitude of force exerted by cells. I finally demonstrated that although the alpha-actinin content was not correlated at all with force magnitude, the relative amount of alpha-actinin as compared to actin content was of key importance to regulate force production.In conclusion, these results identified the biochemical contant of focal adhesion and the relative amounts of molecular motors and crosslinkers per actin as key parameters involved in setting the magnitude of force exerted by cells and thereby shed new light on the mechanisms supporting force generation at the entire cell level

Повний текст джерелаHere we present the results of two distinct projects in the field of cellular mechanics. In the first project, we describe a non-monotonicity in the scaling of force production in actomyosin stress fibers. We develop a continuum mechanical model to explain that non-monotonicity and, using both analytical and numerical techniques, conclude that the scaling is due to an interaction between different physical lengthscales inherent in the actomyosin force-production system. Using singular perturbation methods, we study the model further to make predictions about the physical conditions under which a cell can break symmetry. In the second project, we explore how lipid flow in the plane of the plasma membrane contributes to membrane translocation during cell migration. By numerically solving the Stokes equations, we quantify the magnitude of the force necessary to generate this flow, and analyze how the presence of transmembrane protein obstacles influences the resulting front-to-rear membrane tension gradient. We make several analytic estimates of the mechanical importance of this membrane tension for cell motility.

Повний текст джерелаAction forces have been identified as risk factors. Therefore, the collection and analysis of action forces is an essential part of the ergonomic evaluation. Up to now, there was a lack of a standardized and systematic approach to evaluate action forces, especially in the automotive production. Thus, in the present thesis a methodical approach is described to evaluate action forces systematically. The thesis is divided into four studies. The first study contains the identification of the variety of action forces in the different manufacturing areas of automotive production. The second study describes the detailed analysis of action forces in the assembly shop, which is the manufacturing area with the highest count of action forces in the automotive production. The third study describes the direct measurement of action forces in laboratory conditions. The action forces are applied by a testing machine. The fourth study consists of the direct measurement of action forces, which are applied by subjects. Thereby, the methodical approach to perform direct measurements has been evaluated. The findings of the thesis can be used as a guideline, to evaluate action forces in the automotive production. Also the findings highlight the potential for further research projects

Повний текст джерелаMolecular motors are essential agents of force production in the cells: they convert the chemical energy released by the hydrolysis of ATP into mechanical work. This thesis focuses on myosins, a family of molecular motors responsible for actin-based motility. Myosin VI is unique among all of the myosin superfamily members in that it moves in the opposite direction of all other known myosins. Previous work revealed myosin VI tail ability to fold back, constituting a potential auto-inhibited state that prevents motor activity. Several myosin VI partners, binding to the C-terminal tail of the myosin, have been identified and shown to recruit the motor for different functions. In the first chapter of this thesis, the mechanism allowing the regulation of myosin VI activity has been studied using biochemical and biophysical analysis (SAXS, light scattering, microscopy, binding assays and mutagenesis). GIPC1, the most studied myosin VI partners, promotes myosin dimerization and activation. During my PhD, I have been also involved in two other projects, in line with my thesis project, that have led to the publication of four articles. Two shorter chapters are therefore devoted to these projects. The second chapter of my thesis explores myosin VII activity regulation by its cellular partners. Finally, the third chapter is devoted to the allosteric regulation of myosins activity by small molecules

Повний текст джерелаThe development of very high power lasers in the latest decade opened up new horizons in a various field, such as the production of accelerated ion beams. When a laser beam interacts with a target, the generated beam can contain energetic ions or electrons with a large energy spectrum (1–200 MeV). This energy distribution depends on the laser power and the nature of the target.Physicists studying the interaction between laser and materials are really interested in having very thin (10 µm) ribbons of solid hydrogen that could be used as a target. Indeed, during the interaction between a laser and such a target, a pure proton beam can be created. Protontherapy is one of the main potential applications which uses the special properties of accelerated protons to destroy cancerous tumor. This technique, lighter and cheaper, could replace in the next years huge particle accelerators situated underground the equipped hospitals. This PhD thesis was about developing a way to get and characterize such ribbons, using a new extrusion process.Extrusion of solid hydrogen requires a high pressure (10 MPa to 40 MPa) and a low temperature (below 13K). This is achieved by using the thermodynamic properties of the fluid. First, the cell is filled in with solid H2, then closed. Afterward, the upper part is heated to liquefy the solid. The expansion, resulting from the phase change creates a pressure on the solid hydrogen, located below the liquid. The extrusion is realized through a micron-sized hole at the bottom of the cell. The main difference with a classic extrusion process is the absence of moving parts.First solid hydrogen ribbons (1mm large and 100 microns of thickness) have been obtained in March 2014, leading to an article in a peer review (laser and particle beams (2014) 32,569-575, Continuous production of a thin ribbon of solid hydrogen). The use of a 50 micron nozzle was satisfying but it showed the limitation in the design of the cell, leading to an upgraded one, which will enable to extrude thinner ribbons.A cylindrical nozzle (140 microns diameter) has also been used to obtain long cylinders of solid hydrogen and to be able to understand the solid hydrogen flow in simple geometries. In parallel, several numerical simulations have been carried out to establish the flow behavior of solid hydrogen during the extrusion process. An “home made” model has been developed for which experimental results and numerical calculations fit quite well for different nozzles' geometries.Using small ribbon defaults as velocity tracers, cross-correlation algorithm has also been developed to measure the velocity during the extrusion process. The ribbon thickness is also extracted from image analysis. These results are also correlated by flowmeter measurements and appeared to be accurate.Several laser teams have shown a great interest for these results and a collaboration contract has been signed with the laser PALS team (Prague) to install an updated version of this cryostat, able to be plugged in their vacuum chamber. The team wants to shoot the solid hydrogen target to understand the laser/matter interaction and accelerate proton through the TNSA (Target Normal Sheath Acceleration) principle. It will be the first time such target will be shot. The installation of the cryostat is scheduled by the end of august and the first experiments are planned during november 2015. LULI's laser team at Palaiseau in France is also interested in using these targets and is planning to shoot them in January 2016. In parallel, CNRS physicists of the ILM (Institut Lumière Matière de Lyon) would like to use these targets to generate X-UV radiation

Повний текст джерелаThis thesis work is divided into two parts that relate to each other. The first part investigates driving forces and limiting factors in the customisation of information on packaging and the second part focuses on how the customisation task should be performed in order to obtain high productivity and efficient logistics. Opportunities with hybrid printing solutions where conventional technology is combined with digital printing are discussed.The first of the included papers talks about the driving forces and limiting factors in the customisation of information on packaging and focuses on marketing aspects and consumer value. The second paper investigates the logistical aspects of using digital printing to add information on pre-printed packaging, with the primary focus on the opportunities to reduce changeover time and printing form costs. The third paper investigates how digital printing can be integrated into a packaging line and identifies critical productivity related parameters. These three papers are analysed together in this report, giving input to conclusions about the driving forces and limiting factors in the customisation of information on packaging and how the customisation task should be performed to obtain high productivity and efficient logistics. Hence, this thesis work does not originate solely in one discipline. Digital printing technology, logistics and marketing aspects are all considered to draw conclusions.
It is shown that it is possible to obtain marketing advantages, fulfill market demands better, get increased consumer value and reduced costs by using a hybrid printing solution. There exists at the same time a number of limiting factors, such as print quality demands, additional costs and reliability issues that are crucial to consider before concluding whether or not customisation of information on packaging would be successful in any given business scenario.
Different scenarios for where the customisation task can be inserted into a value chain are defined and discussed. Explicit studies of one of the scenarios are made. This scenario is defined as having a customisation task inline in a packaging line. The other scenarios, customisation at the packaging producer and customisation at the wholesaler/retailer, are not explicitly investigated, but it has been possible to discuss these scenarios as well through the research results obtained. The results show that there are factors that point towards the scenario where digital printing is performed at the producer as being the most beneficial. A number of critical productivity related factors for this scenario are identified in paper III, which gives guidelines on how to obtain high productivity when a digital printing task is integrated into a packaging line. It is finally shown that it is possible to obtain high delivery service and efficient logistics by using a hybrid printing solution. It is, however, of crucial importance that possible drawbacks be considered in order to accurately conclude whether a hybrid printing solution will be successful or not.

Повний текст джерелаBasement membrane (BM) is a dense sheet of specialized extracellular matrix that separates epithelia from underlying tissue. The penetration of cells through BM barriers, called “invasion”, is an important process during normal tissue development and in cancer metastasis. Much has been understood concerning the genetics and signaling of how holes are formed in the BM during invasion. However less is clear about the physical forces involved: how myosin contractility participates in BM removal and how different actin polymerization factors and crosslinkers contribute to the invasive process. To address these questions, we studied an invasion event in a developmental process, anchor cell (AC) invasion in Caenorhabditis elegans. AC breaching of the BM is known to depend on an actin-rich protrusion and the activity of matrix metalloproteases (MMPs), similar to cancer cell invasion. RNAi knockdown of different actin polymerization activators and nucleators, and expression of a dominant negative form of an Arp2/3 complex activator specifically in the AC showed that AC invasion depended strongly on branched filaments formed via WASP/WSP-1 activation of the Arp2/3 complex. Super-resolution microscopy indicated that the AC invasive protrusion was densely packed with filaments, in keeping with the idea that the invasive protrusion was highly branched. We further showed that another Arp2/3 complex activator, WAVE/WVE-1, could enable invasion when WASP/WSP-1 was absent. Formins appeared not to play a major role and actin cross-linking proteins were likewise dispensable for AC invasion. In wild type worms, we observed that myosin activity was not needed for invasion. However it has been reported that cancer cells upregulate myosin contractility to invade in the absence of proteases, so we used a worm deleted for the five main MMPs of the worm genome to test the role of myosin in this context. AC invasion took place in MMP- worms, but with a time delay. RNAi knockdown of different components of the myosin machinery gave no enhancement of the invasion defect. In addition visualization of the actin cytoskeleton in MMP- worms revealed that actin was concentrated in the AC protrusion and barely detectable in the cortex, making it unlikely that myosin contraction of the cortex was helping the cell squeeze through the BM as reported in cancer cells in the absence of proteases. All together these results showed that the invasive cell adapted its branched actin filament polymerization to maintain invasion in different biochemical and environmental contexts. This plasticity is a crucial point that needs to be better understood in order to develop future treatments targeting cancer cell invasion
