Resumen
This study aimed to determine the bioactive compounds and antioxidant activity of macroalgae in Moudolung Waters. The bioactive compounds in seven samples of macroalgae were extracted with methanol. Analysis of macroalgae bioactive compounds was carried out qualitatively by determining the presence of bioactive compounds including alkaloids, flavonoids, saponins, tannins, phenol hydroquinone, and steroids/ terpenoids. antioxidant activity was carried out using the DPPH (2,2-diphenyl-1-picrylhydrazyl-hydrate) method. Data were analyzed descriptively using Microsoft Excel and all data are expressed as mean. The results showed that these seven macroalgae species have bioactive compounds such as alkaloids, flavonoids, saponins, tannins, phenol hydroquinone, and steroids/terpenoids which function as antioxidants. The highest antioxidant activity was the MA6 (Turbinaria ornate) followed by MA1 (Hormopysa triquetra), MA4 (Ulva flexuosa syn. Enteromorpha flexuosa), MA5 (Eucheuma spinosum), MA2 (Sargassum muticum), MA3 (Gracilaria corticate), and MA7 (Ulva reticulata) were 75.25 mg/mL, 90.31 mg/mL, 134.52 mg/mL, 200.22 mg/mL, 216.91 mg/mL, 259.16 mg/mL, and 270.42 mg/mL, respectively. The results suggested that Turbinaria ornate and Hormopysa triquetra could be used as an important substitute for functional ingredients in foods and pharmaceuticals or nutraceuticals.

Resumen
In order to collaboratively explore an environment with a Micro Aerial Vehicle (MAV), an operator needs a mobile interface, which can support the operator’s divided attention. To this end, we developed the Micro Aerial Vehicle Exploration of an Unknown Environment (MAV-VUE) interface, which allows operators with minimal training the ability to remotely explore their environment with a MAV. MAV-VUE employs a concept we term Perceived First-Order (PFO) control, which allows an operator to effectively “fly” a MAV with no risk to the vehicle. PFO control utilizes a position feedback control loop to fly the MAV while presenting rate feedback to the operator. A usability study was conducted to evaluate MAV-VUE. This interface was connected remotely to an actual MAV to explore a GPS-simulated urban environment.

Resumen
ABSTRACT Infection of adult C57BL/6 (B6) mice with mouse adenovirus type 1 (MAV-1) results in dose-dependent encephalomyelitis. Utilizing immunodeficient mice, we analyzed the roles of T cells, T-cell subsets, and T-cell-related functions in MAV-1-induced encephalomyelitis. T cells, major histocompatibility complex (MHC) class I, and perforin contributed to acute disease signs at 8 days postinfection (p.i.). Acute MAV-1-induced encephalomyelitis was absent in mice lacking T cells and in mice lacking perforin. Mice lacking α/β T cells had higher levels of infectious MAV-1 at 8 days, 21 days, and 12 weeks p.i., and these mice succumbed to MAV-1-induced encephalomyelitis at 9 to 16 weeks p.i. Thus, α/β T cells were required for clearance of MAV-1. MAV-1 was cleared in mice lacking perforin, MHC class I or II, CD4+ T cells, or CD8+ T cells. Our results are consistent with a model in which either CD8+ or CD4+ T cells are sufficient for clearance of MAV-1. Furthermore, perforin contributed to MAV-1 disease but not viral clearance. We have established two critical roles for T cells in MAV-1-induced encephalomyelitis. T cells caused acute immunopathology and were required for long-term host survival of MAV-1 infection.

Resumen
This paper presents outdoor fully autonomous control for a Quad-Rotor MAV (Micro Air Vehicle). In case of natural disaster like earthquake, a MAV will be very effective for surveying the site and environment in dangerous area or narrow space, where human cannot access safely. In addition, it will be helpful to prevent secondary disaster. Our Autonomous Rotary-wing MAV is a quad-rotor type MAV which total mass is 660g and is capable of 10 minute outdoor flights. In order to measure the relative position of the MAV, we have installed a sensor-board which includes GPS, gyro, and acceleration sensors on our MAV. So it can achieve fully autonomous flight control with the complete embedded system. We also have installed a wireless camera to our MAV so it can transmit image data to the ground station. This paper describes model based autonomous hovering control, guidance control performance of our quad-rotor MAV.

Resumen
Miniature unmanned aerial vehicle (MAV) is more and more widely used in daily life. The small size of MAVs brings them many advantages like high portability and manoeuvrability. MAVs are playing important roles in many aspects because of their own catachrestic and advantages. There are many kinds of MAVs such as single-rotor MAV, multi-rotor MAV, fixed-wing MAV and bionic MAV. Each of them has its own advantages and drawbacks. The applications of them are decided by these characteristics. In order to better design MAV, in this paper, the advantages and disadvantages of the MAVs are analysed. The four most common kinds of MAVs are discussed in this paper. They have differences in structure and characteristics. The differences between these aspects are displayed in this paper. The suitable application scenario for each kind of MAV is provided based on its own peformance characteristics. This paper may offer a reference for MAV design.

Resumen
Dal mese di Novembre 1991 all'Agosto 2001, 115 pazienti sono stati ricoverati per una Malformazione Artero-Venosa (MAV) presso la Clinica Neurochirurgica dell'Università di Torino. Novantaquattro pazienti su 115 (82%) sono stati ricoverati dopo un sanguinamento. Novantaquattro (82%, 82 sanguinanti, 11 non sanguinanti) sono stati sottoposti a vari trattamenti (chirurgico, endovascolare, radiochirurgico o associazioni dei precedenti). Risanguinamento: Nessuno dei 9 pazienti portatori di MAV non sanguinanti e non sottoposti a trattamento per varie ragioni, ha avuto un sanguinamento nel periodo di follow up di 1–10 anni. In 12 pazienti, su 94 che avevano già avuto una emorragia, abbiamo osservato il risanguinamento della MAV (13%). MAV sanguinanti: Sul totale di 82 pazienti trattati, 43 (53%) sono stati dimessi senza deficit neurologici, 19 (23%) con deficit minori, 11 (13%) con gravi deficit neurologici, 9 pazienti sono deceduti (11%). MAV non sanguinanti: Sul totale di 11 casi trattati, 8 sono stati dimessi senza deficit neurologici (73%), 2 casi con deficit minori (18%) e 1 paziente è deceduto (9%). Le tecniche di trattamento sono state variamente combinate. Il trattamento chirurgico è stato associato a buoni risultati nel 50% dei casi, con mortalità dell '8%. Malformazioni artero-venose sanguinanti: ogni tipo di trattamento di una MAV deve mirare alla sua completa esclusione. In generale il nostro comportamento nel trattamento di pazienti con MAV sanguinante è il seguente: - In caso di MAV superficiali, di volume inferiore a 25–30 cm3 e in aree non eloquenti, l'approccio è chirurgico. - In caso di MAV sulla faccia mesiale dell'emisfero o che interessano la regione del cingolo o il corpo calloso, l'esclusione della MAV può essere ottenuta con l'aggressione chirurgica diretta o con la radiochirurgia eventualmente preceduta da parziale embolizzazione. - Le MAV profonde para o intraventricolari o della testa del n. caudato o strio-capsulo-talamiche possono essere trattate chirurgicamente, ma di solito vengono sottoposte a radiochirurgia. - Le MAV in aree eloquenti, se piccole sono sottoposte a radiochirurgia, se di dimensioni maggiori sono dapprima sottoposte ad embolizzazione e successivamente a radiochirurgia. - Le MAV vicine ad aree eloquenti o che in parte le coinvolgono, ad esempio MAV parieto-occipitali corticali o cortico-sottocorticali sono di solito sottoposte a trattamento chirurgico, eventualmente preceduto da un trattamento endovascolare. Malformazioni artero-venose non sanguinanti: in linea generale le MAV di piccolo volume in aree non eloquenti vengono sottoposte al trattamento chirurgico. Se superano i 25–30 cm3 possono essere sottoposte a trattamento endovascolare e successivamente alla chirurgia. Le MAV superiori ai 25–30 cm3 in aree eloquenti, in particolare se irrorate da feeders profonde non vengono di solito sottoposte ad alcun trattamento.

Resumen
The drift of inertial navigation system (INS) will lead to large navigation error when a low-cost INS is used in microaerial vehicles (MAV). To overcome the above problem, an INS/optical flow/magnetometer integrated navigation scheme is proposed for GPS-denied environment in this paper. The scheme, which is based on extended Kalman filter, combines INS and optical flow information to estimate the velocity and position of MAV. The gyro, accelerator, and magnetometer information are fused together to estimate the MAV attitude when the MAV is at static state or uniformly moving state; and the gyro only is used to estimate the MAV attitude when the MAV is accelerating or decelerating. The MAV flight data is used to verify the proposed integrated navigation scheme, and the verification results show that the proposed scheme can effectively reduce the errors of navigation parameters and improve navigation precision.

Resumen
ABSTRACT Adenovirus fiber knobs are the capsid components that interact with binding receptors on cells, while an Arg-Gly-Asp (RGD) sequence usually found in the penton base protein is important for the interaction of most adenoviruses with integrin entry receptors. Mouse adenovirus type 1 (MAV-1) lacks an RGD sequence in the virion penton base protein. We tested whether an RGD sequence found in the MAV-1 fiber knob plays a role in infection. Treatment of cells with a competitor RGD peptide or a purified recombinant RGD-containing fiber knob prior to infection resulted in reduced virus yields compared to those of controls, indicating the importance of the RGD sequence for infection. An investigation of the role of integrins as possible receptors showed that MAV-1 yields were reduced in the presence of EDTA, an inhibitor of integrin binding, and in the presence of anti-αv integrin antibody. Moreover, mouse embryo fibroblasts that were genetically deficient in αv integrin yielded less virus, supporting the hypothesis that αv integrin is a likely receptor for MAV-1. We also investigated whether glycosaminoglycans play a role in MAV-1 infection. Preincubation of MAV-1 with heparin, a heparan sulfate glycosaminoglycan analog, resulted in a decrease in MAV-1 virus yields. Reduced MAV-1 infectivity was also found with cells that genetically lack heparan sulfate or cells that were treated with heparinase I. Cumulatively, our data demonstrate that the RGD sequence in the MAV-1 fiber knob plays a role in infection by MAV-1, αv integrin acts as a receptor for the virus, and cell surface heparin sulfate glycosaminoglycans are important in MAV-1 infection.

Resumen
ABSTRACT mSur2, a subunit of the Mediator complex, is required for efficient mouse adenovirus type 1 (MAV-1) replication (L. Fang, J. L. Stevens, A. J. Berk, and K. R. Spindler, J. Virol. 78:12888-12900, 2004). We examined the contributions of early-region 1A (E1A) to mSur2 function in MAV-1 replication with E1A mutant viruses. At a multiplicity of infection (MOI) of 1, viruses containing CR3 replicated better in Sur2+/+ mouse embryonic fibroblasts (MEFs) than in Sur2−/− MEFs. In contrast, viruses lacking CR3 replicated no better in Sur2+/+ than in Sur2−/− MEFs. This result supports the hypothesis that the E1A CR3-mSur2 interaction is important for MAV-1 replication. However, at an MOI of 0.05, viruses lacking CR3 showed replication defects in Sur2−/− MEFs compared to Sur2+/+ MEFs, suggesting an E1A CR3 interaction-independent function of mSur2 in MAV-1 replication in cell culture. Paradoxically, CR1Δ, CR2Δ, and CR3Δ mutant viruses replicated slightly more efficiently than wild-type (wt) MAV-1 and E1A null mutant viruses in Sur2−/− MEFs at an MOI of 0.05. Coinfection of Sur2−/− MEFs with wt MAV-1 and CR1Δ, CR2Δ, or CR3Δ mutant viruses rescued the defects of wt MAV-1 replication. This result suggests that an inhibiting effect on wt E1A protein expression and/or E1A function might account for the severe viral replication defect of MAV-1 in Sur2−/− MEFs at an MOI of 0.05. Moreover, titrations of virus yields from infected brains of inbred strains of mice showed that E1A null and CR3Δ mutant viruses had a significant defect in virus replication compared to wt MAV-1. This result supports the hypothesis that the MAV-1 E1A-mSur2 interaction is important in MAV-1 replication in mice.

Resumen
ABSTRACT Infection with mouse adenovirus type 1 (MAV-1) results in fatal acute encephalomyelitis in susceptible mouse strains via infection of brain endothelial cells. Wild-type (wt) MAV-1 causes less brain inflammation than an early region 3 (E3) null virus in C57BL/6 mice. A mouse brain microvascular endothelial cell line infected with wt MAV-1 had higher expression of mRNAs for the proinflammatory chemokines CCL2 and CCL5 than mock- and E3 null virus-infected cells. Primary mouse brain endothelial cells infected with wt virus had elevated levels of CCL2 compared to mock- or E3 null virus-infected cells. Infection of C57BL/6 mice with wt MAV-1 or the E3 null virus caused a dose-dependent breakdown of the blood-brain barrier, primarily due to direct effects of virus infection rather than inflammation. The tight junction proteins claudin-5 and occludin showed reduced surface expression on primary mouse brain endothelial cells following infection with either wt MAV-1 or the E3 null virus. mRNAs and protein for claudin-5, occludin, and zona occludens 2 were also reduced in infected cells. MAV-1 infection caused a loss of transendothelial electrical resistance in primary mouse brain endothelial cells that was not dependent on E3 or on MAV-1-induced CCL2 expression. Taken together, these results demonstrate that MAV-1 infection caused breakdown of the blood-brain barrier accompanied by decreased surface expression of tight junction proteins. Furthermore, while the MAV-1-induced pathogenesis and inflammation were dependent on E3, MAV-1-induced breakdown of the blood-brain barrier and alteration of endothelial cell function were not dependent on E3 or CCL2.

The process of estimating motion trajectory through an unknown environment from a monocular image sequence is one of the main challenges in Micro Air Vehicle (MAV) navigation. Today MAVs are becoming more and more prevalent in both civilian and military operations. However, with their reduction in size compared to traditional Unmanned Aircraft Vehicles (UAVs), the computational power and payload that can be carried onboard is limited. While there is ample research in motion estimation for systems that are deployed on the ground, have various sensors, as well as multiple cameras, a current challenge consists of deploying minimalistic systems suited specifically for MAVs. This thesis presents a novel approach for six-degrees of freedom motion estimation using a monocular camera containing a Field-Programmable-Gate-Array (FPGA). Most implementations using a monocular camera onboard MAVs stream images to a ground station for processing. However, an FPGA can be programmed for feature extraction, so instead of sending raw images, information is encoded by the FPGA and only frame information, feature locations, and descriptors are transmitted. This onboard precomputation greatly reduces bandwidth usage and ground station processing. The objectives of this research are (1) to show how the raw computing power of an FPGA can be exploited in this application and (2) to evaluate the performance of such a system against a traditional monocular camera implementation. The underlying motivation is to bring MAV systems closer to complete autonomy, meaning all the computation needed for estimation and navigation is carried out autonomously and onboard.

Resumen
A new visual registration algorithm (Adaptive Iterative Closest Keypoint, AICK) is tested and evaluated as a positioning tool on a Micro Aerial Vehicle (MAV). Captured frames from a Kinect like RGB-D camera are analyzed and an estimated position of the MAV is extracted. The hope is to find a positioning solution for GPS-denied environments. This thesis is focused on an indoor office environment. The MAV is flown manually, capturing in-flight RGB-D images which are registered with the AICK algorithm. The result is analyzed to come to a conclusion if AICK is viable or not for autonomous flight based on on-board positioning estimates. The result shows potential for a working autonomous MAV in GPS-denied environments, however there are some surroundings that have proven difficult. The lack of visual features on e.g., a white wall causes problems and uncertainties in the positioning, which is even more troublesome when the distance to the surroundings exceed the RGB-D cameras depth range. With further work on these weaknesses we believe that a robust autonomous MAV using AICK for positioning is plausible.
En ny visuell registreringsalgoritm (Adaptive Iterative Closest Keypoint, AICK) testas och utvärderas som ett positioneringsverktyg på en Micro Aerial Vehicle (MAV). Tagna bilder från en Kinect liknande RGB-D kamera analyseras och en approximerad position av MAVen beräknas. Förhoppningen är att hitta en positioneringslösning för miljöer utan GPS förbindelse, där detta arbete fokuserar på kontorsmiljöer inomhus. MAVen flygs manuellt samtidigt som RGB-D bilder tas, dessa registreras sedan med hjälp av AICK. Resultatet analyseras för att kunna dra en slutsats om AICK är en rimlig metod eller inte för att åstadkomma autonom flygning med hjälp av den uppskattade positionen. Resultatet visar potentialen för en fungerande autonom MAV i miljöer utan GPS förbindelse, men det finns testade miljöer där AICK i dagsläget fungerar undermåligt. Bristen på visuella särdrag på t.ex. en vit vägg inför problem och osäkerheter i positioneringen, ännu mer besvärande är det när avståndet till omgivningen överskrider RGB-D kamerornas räckvidd. Med fortsatt arbete med dessa svagheter är en robust autonom MAV som använder AICK för positioneringen rimlig.

Resumen
Flapping wing propulsion has the potential to revolutionise the field of Micro Aerial Vehicles (MAVs), but little is known about the effect of flapping motion on the performance of flapping wings. Prototype MAVs have achieved flight with passive flapping wings moving in a sinusoidal flapping motion, but the possible benefits of alternative flapping motions have not been studied in detail. This thesis presents the development of an Integrated Testing System (ITS), which allows the evaluation of flapping wing performance for different flapping motions. A detailed parametric study of the effect of flapping motion on wing performance is performed, and the optimal flapping motion for several passive flapping wings is determined by hardware-in-the-loop optimisation of two wing performance metrics. The developed ITS was able to automatically test a variety of passive flapping wings, and demonstrated precise control of the flapping motion and accurate and repeatable measurements of average lift force, mechanical power, and wing twist angle. The parametric study revealed that of the three flapping motions tested, the sinusoidal flapping motion generated the highest lift force, but a smoothed triangular motion was able to generate lift significantly more efficiently under load. The optimal flapping motion was successfully determined for three flapping wings, and was found to increase the loaded effciency of the wings by an average of 31% over a sinusoidal flapping motion. The determined optimal motion was almost identical for the three tested wings, and was found to strongly resemble the flapping motion of insects These findings demonstrate that significant improvements in the performance of passive flapping wings can be achieved by relatively minor variations of the flapping motion. This increased understanding will ideally lead to more efficient flapping wing MAVs with higher payloads, longer flight times, and improved performance.

Advances in millimeter-scale fabrication processes have enabled rapid progress towards the development of flapping wing micro air vehicles with wing spans of several centimeters and a system mass on the order of 100mg. Concerning flight stability and control mechanisms for these mass and power limited devices, this dissertation explores the use of underactuated “mechanically intelligent” systems to passively regulate forces and torques encountered during flight. Several experiments demonstrate passive torque regulation in physical flapping wing systems. Finally, this dissertation concludes with a detailed description of the Printed Circuit MEMS manufacturing process, developed to address the practical problem of building complex insect-scale machines.

Resumen

This thesis project has been carried out at Linköpings universitet at the Department of Mechanical Engineering. The emphasis of the project lies in the exploration of automatic selection of components for a propulsion kit. Specifically for this project, propulsion based on electric power and meeting the requirements for use in a Micro Aerial Vehicle (MAV). The key features include a systematic selection method based on user criterias and a model for evaluating propeller performance. These are implemented in a program written as a part of the project. The conclusion is that it is possible to make a program capable of a component selection and that the programs usability is mainly reliant on three factors: model for propeller evaluation, method of selection and the quality of the component database.

Texto completo
Resumen
This thesis addresses flight control of the perch landing maneuver for micro-aerial vehicles. A longitudinal flight model is constructed for a pigeon-sized aircraft. In addition to a standard elevator control surface, wing-rotation also considered as a non-standard actuator for increasing low-speed aerodynamic braking. Optimal state and control trajectories for the perch landing maneuver are computed using commercial software. A neighboring optimal control law is then developed and implemented in a set of flight simulations. Simulations are run with both a quasisteady and an unsteady aerodynamic model. The effectiveness of wing rotation and of the neighboring optimal control law is discussed, as is the importance of unsteady aerodynamics during the maneuver. Wing rotation was found to be minimally effective in this case, but it showed potential to be more effective in further research. The unsteady aerodynamic model has significant influence over the success or failure of the maneuver.

Resumen
Mycobacterium avium subsp. paratuberculosis (MAP) is the etiological agent of a severe inflammatory bowel disease (IBD) in ruminants, known as Johne’s disease or paratuberculosis. Johne’s disease is considered to be one of the most serious diseases affecting dairy cattle both in Israel and worldwide. Heavy economic losses are incurred by dairy farmers due to the severe effect of subclinical infection on milk production, fertility, lower disease resistance and early culling. Its influence in the United States alone is staggering, causing an estimated loss of $1.5 billion to the agriculture industry every year. Isolation of MAP from intestinal tissue and blood of Crohn's patients has lead to concern that it plays a potential pathogenic role in promoting human IDB including Crohn’s disease. There is great concern following the identification of the organism in animal products and shedding of the organism to the environment by subclinically infected animals. Little is known about the molecular basis for MAP virulence. The goal of the original proposed research was to identify MAP genes that are required for the critical stage of initial infection and colonization of ruminants’ intestine by MAP. We proposed to develop and use signature tag mutagenesis (STM) screen to find MAP genes that are specifically required for survival in ruminants upon experimental infection. This research projected was approved as one-year feasibility study to prove the ability of the research team to establish the animal model for mutant screening and alternative in-vitro cell systems. In Israel, neonatal goat kids were repeatedly inoculated with either one of the following organisms; MAP K-10 strain and three transposon mutants of K-10 which were produced and screened by the US PI. Six months after the commencement of inoculation we have necropsied the goats and taken multiple tissue samples from the jejunum, ileum and mesenteric lymph nodes. Both PCR and histopathology analysis indicated on efficient MAP colonization of all the inoculated animals. We have established several systems in the Israeli PI’s laboratory; these include using IS900 PCR for the identification of MAP and using HSP65-based PCR for the differentiation between MAV and MAP. We used Southern blot analysis for the differentiation among transposon mutants of K-10. In addition the Israeli PI has set up a panel of in-vitro screening systems for MAP mutants. These include assays to test adhesion, phagocytosis and survival of MAP to/within macrophages, assays that determine the rate of MAPinduced apoptosis of macrophages and MAP-induced NO production by macrophages, and assays testing the interference with T cell ã Interferon production and T cell proliferation by MAP infected macrophages (macrophage studies were done in BoMac and RAW cell lines, mouse peritoneal macrophages and bovine peripheral blood monocytes derived macrophages, respectively). All partners involved in this project feel that we are currently on track with this novel, highly challenging and ambitious research project. We have managed to establish the above described research systems that will clearly enable us to achieve the original proposed scientific objectives. We have proven ourselves as excellent collaborative groups with very high levels of complementary expertise. The Israeli groups were very fortunate to work with the US group and in a very short time period to master numerous techniques in the field of Mycobacterium research. The Israeli group has proven its ability to run this complicated animal model. This research, if continued, may elucidate new and basic aspects related to the pathogenesis MAP. In addition the work may identify new targets for vaccine and drug development. Considering the possibility that MAP might be a cause of human Crohn’s disease, better understanding of virulence mechanisms of this organism might also be of public health interest as well.
