Full textCellulosa nanofibriller (CNF) är ett förnybart material med unika styrkeegenskaper. En svårighet med produktion av CNF är att CNF suspensioner innehåller stora mängder vatten. Om volymerna av CNF suspensioner kan minskas med avvattning genom centrifugering, då kan transport- och lagerkostnader sänkas. Målet med det här examensarbetet är att undersöka vilken inverkan olika parametrar har på CNF-avvattning genom centrifugering och identifiera optimala förhållanden för maximalt avlägsnande av vatten. En laboratoriestudie utfördes på fyra olika material. De fyra materialen är 2 w% enzymatiskt behandlad CNF (CNF1), 1.9 w% karboxymetylerad CNF (CNF2) och två kommersiella prover (1.9 w% CNFA och 1.8 w% CNFB). Den huvudsakliga metoden var analytisk centrifugering upp till maximalt 2330 g. De testade parametrarna var initial koncentration innan centrifugering, temperatur, NaCl tillsats, pH, och applicerat fast kompressionstryck (g-kraft och ytvikt). Förutom centrifugeringsexperimenten så karaktäriserades the fyra mmaterialen med laser diffraktion, UV-vis absorption, dynamisk ljusspridning och vägningar av torrhalt. Analys av den experimentella data som insamlats visar att en ökad initial koncentration ger en högre slutkoncnentration, men mindre vatten kan bortföras. Temperaturförändringar har ingen effekt på separation av CNF och vatten. Vid ett applicerat fast kompressibelt tryck på 3 kPa och en initial koncentration 1.5 w% kan koncentrationerna 5.5 w%, 1.5 w%, 4.0 w%, och 4.3 w% nås för CNF1, CNF2, CNFA, och CNFB. Efter extrapolering av polynoma funktioner passad till experimentell data förutspås att koncentrationerna 9.1 w%, 1.5 w%, 6.9 w%, och 7.9 w% kan nås för CNF1, CNF2, CNFA, and CNFB vid 22 kPa och en initial koncentration på 1.5 w%. Förtjockningen av CNF suspensioner som kan, eller förutspås kunna nås genom centrifugering i det här examensarbetet innebär att det är möjligt att avlägsna stora mängder vatten, till exempel kan vatteninnehållet i CNF1 minskas från 65.7 liter/kg CNF till 10.0 liter/kg CNF vid 22 kPa fast kompressionstryck. Koncentrationerna vid 22 kPa fast kompressionstryck är extrapolerade från exprimentell data <3 kPa fast kompressionstryck. Den karboy- metylerade CNF2 kan inte avvattnas om den inte späds ut eller om salt eller pH justeras. Detta är direkt kopplat till de elektrostatiska krafterna i suspensionen och Debye längden. Tillsats av salt eller sänkt pH eliminerar också de koncentrationsgradienter som kan förekomma i utspädda centrifugerade CNF2 suspensioner.

Effective separation and purification of biopharmaceutical products from the media in which they are produced continues to be a challenging task. Such processes usually involve multiple steps and the overall product loss can be significant. As an integrative technique, high gradient magnetic separation (HGMS), together with the application of functional magnetic particles, provides many advantages over traditional techniques. However, HGMS has a number of drawbacks; and its application is limited because it is inherently a batch process and it is difficult to recycle the magnetic nanoparticles. This thesis explores the development of a new type of continuous magnetic separation process, called magnetically enhanced centrifugation (MEC), which exploits the interactions of magnetic particles with magnetic field gradients, forced convective flows and large centrifugal forces. Magnetically susceptible wires in a uniform magnetic field facilitate the capture and aggregation of magnetic particles on wires, and a centrifugal force perpendicular to the magnetic force conveys the particle sludge parallel to the wires in a continuous mode. The primary focus of this thesis is multi-scale modeling and simulation to understand the underlying physics of MEC processes. The potential of MEC as an effective unit operation for biopharmaceutical downstream processing has been demonstrated. Unlike traditional batch-mode HGMS, MEC has a great advantage in that it can be operated continuously as magnetic particles captured on wire surface are constantly removed.
(cont.) A dimensionless model for simulating the trajectories of magnetic particles in combined magnetic and flow fields has been developed. The model was first applied to single wire configurations and then extended to multi-wire arrays. It was shown that modified rhombic arrays can provide high capture efficiency while maintaining low pressure drop. It is also shown that capture efficiencies based on results for clean, particle-free wires, may be seriously in error because the particle buildup that accumulates on the wire significantly distorts the flow and the magnetic fields and thus influences the particle trajectories. The dynamic buildup growth process was treated as a moving-boundary problem. Simulation results have shown that the capture efficiency decreases dramatically as particle buildup volume increases. In addition, the influence of particle chaining under magnetic dipole-dipole forces on separation efficiency has been investigated. Magnetic particles form chains as soon as they enter a background magnetic field, and are captured in the form of particle chains. The hydrodynamic force on particle chains was calculated using a 3-D CFD simulation. The capture radius calculated with considering the chaining effect is few times as great as the capture radius calculated assuming individual particles. Bench-top MEC experiments have shown that magnetic particle buildup generally comprises two layers with distinct structures: a spiky layer with all chains parallel to the magnetic field, and a densely-packed layer near the wire.
(cont.) This unique structure reflects the dominance of magnetic forces near the wire and of magnetic dipole-dipole interactions at locations further from the wire. As more and more particles accumulate on the wire surface, the centrifugal force can overcome the cohesion of the layer or the adhesion of the layer to the wire, leading to movement of the buildup material. The onset of such movement can be achieved either by increasing the centrifugal force or by increasing the buildup height. Energy and force analyses have been carried out to study various scenarios of buildup movement. For monodisperse magnetic particles, four scenarios can be expected: chain-like layer collapsing down (I), rigid body movement (II), buildup breakage (III), and mixed behavior of rigid body movement and buildup breakage (IV). A set of design formulas were derived to predict buildup structure and different scenarios. Useful scenario and operating regime diagrams were obtained. A discrete element modeling (DEM) package was developed to study the dynamics and rheological behavior of highly concentrated magnetic particle systems. For monodisperse magnetic particles, simulation results confirmed the four regions of the scenario diagram as predicted by force arguments. For polydisperse magnetic particles, DEM simulations showed that the buildup exhibits solid-like behavior when centrifugal effects are small, and liquid-like behavior with a continuous velocity profile when centrifugal effects are large.
(cont.) DEM simulations were able to predict the three dimensional effects, including the buildup profiles at the wire tip. Taken together, the results of this work provide a general strategy that can be used as a starting point for the design, evaluation, and optimization of magnetically enhanced processes that are suitable for biopharmaceutical downstream processing.

Artificial gravity (AG) created by short-radius centrifugation is a promising countermeasure to the physiological de-conditioning that results from long-duration spaceflight. However, as on Earth, gravity alone does not ensure fitness. We will need to supplement passive exposure to AG with physical exercise to achieve a comprehensive countermeasure. Before AG exercise can be deemed safe and effective, we must understand how Coriolis accelerations and a gravity gradient affect our biomechanics and how centrifuge-based exercises differ from Earth-upright ones. Two experiments were designed to investigate the squat biomechanics while upright in the laboratory and while lying supine on a horizontal, clockwise-rotating short-radius centrifuge at speeds up to 30 revolutions per minute. Constant force springs provided additional resistive force up to 25% of body weight. Dependent measure included the three-dimensional position of the left and right knee, left and right foot reaction forces, and muscle activity. We investigated the Coriolis-induced mediolateral knee perturbations and the sensory-motor after-effects from a multiple repetition protocol. The upright and centrifuge biomechanics were compared for similarities and differences between them. In addition, a two-dimensional kinematic model was developed to predict foot reaction forces, Coriolis accelerations, and joint torques.
(cont.) Our results show that mediolateral knee travel during the AG squats was 1.0 to 2.0 centimeters greater than Earth-upright squats. Increasing the rotation rate or adding resistive force did not affect the results. The peak foot forces increased with rotation rate, but rarely exceeded 200% body weight. The ratio of left-to-right foot force during centrifugation was non-constant and approximately sinusoidal, suggesting a postural correction for the Coriolis accelerations. There was a qualitative difference in the foot force vs. knee angle profile between upright and centrifuge-supine because of the centripetal acceleration. Muscle activity, however, was qualitatively similar between the conditions. The kinematic model was used to evaluate the exercise safety and extend the results to larger-radius centrifuges. We conclude that centrifugation provides a unique and challenging environment for exercise and that a brief artificial gravity squat can be carried out safely. The results are extended to cycle ergometry, when possible, and recommendations are made for future AG squat protocols.

Artificial Gravity (AG) provided by short-radius centrifugation is a promising countermeasure to the health problems associated with long duration human spaceflight. Head-turns performed during centrifugation, however, trigger a disturbing vestibular response that is only qualitatively understood. In order to design an efficient incremental adaptation procedure, the present study investigates the quantitative aspect of the vestibular side effects associated with AG, in particular, the relationship among crosscoupled stimulation, vestibular response, and adaptation. We tested 20 young adults with supine right-quadrant yaw head-turns performed in a dark environment during short-radius centrifugation. We studied the changes in vestibular response and adaptation to head-turns at different levels of cross-coupled stimulation. Nine combinations of head-turn angle (20°, 40° or 80°) with centrifugevelocity (12, 19 or 30 rpm) were tested over two consecutive days.
(cont.) There were four key findings: 1. All measures, except the slow-phase velocity (SPV) peak amplitude of the vestibulo-ocular reflex, decrease significantly between the two experimental days, which demonstrates that significant adaptation is achieved. 2. Large head-angles lead to longer vertical vestibulo-ocular reflex time-constants than smaller angles do, but do not lead to greater adaptation. 3. In the nose-up position, the perceived body-tilt is highly correlated with the true tilt of the gravito-inertial force at mid-chest level. 4. The SPV-peak amplitude and all subjective ratings except body-tilt show significant correlation with the intensity of the cross-coupled stimulus (CCS): the larger the CCS, the stronger the vestibular response.

Human short-radius centrifugation (SRC) is being investigated as a volume-efficient means of delivering intermittent doses of "artificial gravity" to counter the deleterious effects of long exposures to weightlessness. Rotation rates on short radius centrifuges are high to provide the needed g-loading, and therefore entail a variety of unusual vestibular stimuli when certain head movements are made. Since these movements can elicit inappropriate nystagmus, illusions of tumbling, and motion sickness, efforts have been made to adapt people to the stimuli. So far these efforts have been successful in showing that people will adapt to at least one plane of head motion, the yaw (transverse) plane, during supine head-on-axis rotation. However, astronauts must be adapted to all planes of head motion if they are to function normally on the centrifuge. If adaptation to yaw head turns transferred to some extent to pitch (sagittal) plane turns, or any other plane of motion, it would greatly simplify and hasten the adaptation process. To investigate if transfer of adaptation across planes is possible, 10 subjects in the Experimental Group performed a sufficient number of yaw plane head turns to demonstrate adaptation. Adaptation was indicated by decreases in metrics of the off-axis vestibuloocular reflex induced by the head turns, and by subjective ratings of illusory motion. A block of pitch movements was performed before and after the yaw movements, and these two pitch blocks were compared to assess how much adaptation to pitch head turns had taken place. The same procedure was followed on a subsequent day. A Control Group of 10 subjects performed only the blocks of pitch turns, and their adaptation was compared to the adaptation to pitch turns measured in the Experimental
(cont.) Group. While both Control and Experimental Groups showed statistically significant signs of adaptation to pitch head turns, we failed to find any significant differences between the amounts of adaptation. If true, this result implies that adaptation to SRC may need to be performed one plane of motion at a time. Additionally, it implies that the brain and vestibular system does not build up a generalized model of SRC stimulation, but rather builds adaptation one input at a time.

(cont.) not build up adaptation, all subjects in the experimental group who completed the protocol showed signs of adaptation to the stimulus. Only one subject did not complete the five sessions, setting the drop-out rate at about 14%. If this conclusion holds true with more subjects, then a better protocol of adaptation has been unveiled.
In order to counteract the debilitating effects of the space environment on the human body, short-radius intermittent centrifugation is investigated as a possible means to expose astronauts to artificial gravity. Whereas AG is efficient in providing stimuli for muscles, bones and cardiovascular system, short-radius centrifugation elicits discomfort and illusory sensations of motion if particular head movements are made while spinning. Past research has shown that human beings can adapt to these sensations and undergo various stimuli without the disturbing effects of motion sickness, sensations of tumbling and inappropriate eye movements. However, current protocols for adaptation basically consist in repeated exposure to the discomfort. This solution is not satisfactory because the drop-out rate oscillates between 30 and 50%. Since it is not acceptable to spend days of training on astronauts who, in the end, because of this training, could become unsuitable for flight, it is of primary importance to find a training protocol that achieves adaptation without going through permanent discomfort. Incremental exposure to centrifugation is expected to be a compromised protocol to bring trainees to adaptive level without exposing them to maximum discomfort. Seven subjects were exposed to centrifugation during a five-day protocol, over which the speed of rotation was progressively increased. As in previous protocols of adaptation, subjects performed provocative head movements at all speeds. A control experiment had ten subjects exposed to centrifugation without making head turns, in order to verify to what extent the experimental conditions of measurement impact the subjects' behavior and reactions. While subjects in the control experiment did

Long-duration spaceflight results in severe physiological deconditioning, threatening the success of interplanetary travel. Exercise combined with artificial gravity provided by centrifugation may be the comprehensive countermeasure needed to prevent such deconditioning. The aims of this study were (1) to characterize the physiological responses to longitudinal g-gradient and high g-levels during short-radius centrifugation, and (2) to quantify the fitness benefits of an eight-week exercise program on a short-radius centrifuge. In the first experiment, we utilized a tilting short-radius centrifuge to investigate heart rate, blood pressure, and calf volume responses to high g-level and g-gradient centrifugation with and without light exercise (stepping in place). All measures increased significantly with increasing g-level and increasing g-gradient, but these effects were reduced significantly when the subject stepped in place. In the second experiment, we quantified the effectiveness of an eight-week exercise program using a stair-stepper and resistive arm bands on a horizontally-rotating short radius centrifuge. Healthy, previously sedentary subjects exercised at a constant heart rate three times per week for eight weeks, and underwent measurements to test aerobic capacity and endurance, strength, and body composition at weeks 0, 4, and 8. Eight subjects successfully completed 24 exercise sessions with little or no discomfort. After eight weeks of exercise, we found significant improvements in aerobic capacity (increased work rate for a given heart rate, increased stepping endurance), muscular strength (increased number of push-ups), and body composition (decreased leg fat percentage, increased pelvic bone mineral content).
(cont.) Stepping in place significantly reduced the physiological responses to increasing g-level and g-gradient, suggesting that subjects may be able to better tolerate exposure to high-g centrifugation if they exercise. Further, an eight-week exercise program using a stair-stepper on a short-radius centrifuge resulted in improvements to aerobic capacity, strength, and body composition. These two studies demonstrate the feasibility and benefits of exercise in an artificial gravity environment.
