Abstract:
The forest tree species Hevea brasiliensis is extensively planted in the humid tropics to meet the increasing demand for natural rubber. Huge quantities of planting stock are therefore needed. The seed option remains the easiest and cheapest way to establish plantations of rubber trees but those show a great variability for vigor and also for latex yield. The rationale of produ- cing clones for overcoming this variability was already obvious in the early 1910’s but due to the difficulties encountered at that time for rooting shoots, grafting was used as an alternative cloning method. The striking increase in yield noticed from the graft-derived clonal plantations warranted their large scale development. Eventually, the budded clones by virtue of their much higher and uniform produc- tivity supplanted the seedlings in most industrial plantations. However, grafting is also associated with drawbacks and for decades efforts aiming at mass producing selected rubber tree clones on their own roots by rooted cuttings have been pur- sued. However, this approach was pro- gressively abandoned due to disappoin- ting rooting results and, from the 70’s onwards, priority has been given to in vitro methods which were booming during this period. But despite 40 years of heavy investments, industrial H. brasiliensis clones could still not be mass micropro- pagated in vitro efficiently enough to meet the requirements of large scale produc- tion. The situation may change radically soon, however, due to the development of new nursery techniques adapted to the mass clonal production by rooted cuttings of any H. brasiliensis selected genotype. Efforts to improve the techniques as well as the establishment of new field trials are underway in order to determine if self-rooted rubber tree clones are more productive than grafted ones. This old issue is becoming of overriding impor- tance considering the increasing pres- sure on land availability reducing thereby the prospects for expanding rubber tree plantations.

Abstract. We assessed the influence of the marine diazotrophic cyanobacterium Trichodesmium on the bio-optical properties of western tropical South Pacific (WTSP) waters (18–22∘ S, 160∘ E–160∘ W) during the February–March 2015 OUTPACE cruise. We performed measurements of backscattering and absorption coefficients, irradiance, and radiance in the euphotic zone with a Satlantic MicroPro free-fall profiler and took Underwater Vision Profiler 5 (UPV5) pictures for counting the largest Trichodesmium spp. colonies. Pigment concentrations were determined by fluorimetry and high-performance liquid chromatography and picoplankton abundance by flow cytometry. Trichome concentration was estimated from pigment algorithms and validated by surface visual counts. The abundance of large colonies counted by the UVP5 (maximum 7093 colonies m−3) was well correlated to the trichome concentrations (maximum 2093 trichomes L−1) with an aggregation factor of 600. In the Melanesian archipelago, a maximum of 4715 trichomes L−1 was enumerated in pump samples (3.2 m) at 20∘ S, 167 30∘ E. High Trichodesmium abundance was always associated with absorption peaks of mycosporine-like amino acids (330, 360 nm) and high particulate backscattering, but not with high Chl a fluorescence or blue particulate absorption (440 nm). Along the west-to-east transect, Trichodesmium together with Prochlorococcus represented the major part of total chlorophyll concentration; the contribution of other groups were relatively small or negligible. The Trichodesmium contribution to total chlorophyll concentration was the highest in the Melanesian archipelago around New Caledonia and Vanuatu (60 %), progressively decreased to the vicinity of the islands of Fiji (30 %), and reached a minimum in the South Pacific Gyre where Prochlorococcus dominated chlorophyll concentration. The contribution of Trichodesmium to zeaxanthin was respectively 50, 40 and 20 % for these regions. During the OUTPACE cruise, the relationship between normalized water-leaving radiance (nLw) in the ultraviolet and visible and chlorophyll concentration was similar to that found during the BIOSOPE cruise in the eastern tropical Pacific. Principal component analysis (PCA) of OUTPACE data showed that nLw at 305, 325, 340, 380, 412 and 440 nm was strongly correlated to chlorophyll and zeaxanthin, while nLw at 490 and 565 nm exhibited lower correlations. These results, as well as differences in the PCA of BIOSOPE data, indicated that nLw variability in the greenish blue and yellowish green during OUTPACE was influenced by other variables associated with Trichodesmium presence, such as backscattering coefficient, phycoerythrin fluorescence and/or zeaxanthin absorption, suggesting that Trichodesmium detection should involve examination of nLw in this spectral domain.

Abstract:
Carbon nanotubes grafted with stearyl alcohol (CNTs-SA) was used to enhance the thermal conductivities of the microcapsules. Differential Scanning Calorimeter (DSC) and thermogravimetry (TG) analysis method are employed to measure thermal properties of the prepared MicroPCM containing the grafted CNTs (MicroPCM/CNTs-SA). The results indicated the phase change temperature and latent heat of MicroPCM/CNTs-SA was 26.2°C and 47.7J/g. An increase in thermal conductivity, thermal stability of MicroPCM/CNTs-SA was observed. After 100 heating and cooling cycles, MicroPCM/CNTs-SA still had better durability and thermal stability.

Abstract:
Microarc oxidation coating and microarc oxidation-fluorocarbon coating were prepared on the surface of AZ80 magnesium alloy profiles. The phase structure, surface morphology and corrosion resistance of the coatings were investigated using SEM, XRD, copper sulfate spot test and polarization curve test. The main phase compositions of the microarc oxidation coatings were MgO, Mg2SiO4, MgSiO3, MgF2 and MgAl2O4. With increasing pulse voltage, the oxidation coating became thicker and the microstructure of the coating surface became compact; therefore the coating corrosion resistance was improved. The oxidation coating with pulse voltage of microarc oxidation controlled between 300-438V obtained the best corrosion resistance. The corrosion current density of magnesium alloy reduced 1-3 orders of magnitude after microarc oxidation treatment with increasing pulse voltage, and the corrosion resistance of microarc oxidation-fluorocarbon coating is desirable.

Abstract:
In this study, we used a micro-ultrasound (microUS) system that we developed in-house as an alternative method for tumor growth calipers. In addition, microUS was combined with small-animal positron-emission tomography (microPET) for tumor metastatic assessment. MicroUS provides anatomical information that can be used for tumor volume measurements while microPET is a functional imaging method with positron-emitting radiophamaceuticals, such as 18F-labeled deoxyglucose, [18F]FDG. In this study, microUS and microPET were performed in a mouse tumor longitudinal study (2–8 weeks), both with 3D tumor segmentation and volume measurements. Compared with vernier calipers, microPET generally overestimated tumor volumes during weeks 2–4 due to its inadequate spatial resolution. During weeks 5–8, standard deviations of microPET results were large due to tumor hypoxia or necrosis. On the contrary, microUS tumor volume measurements were more reliable as they were less affected by these factors. Nonetheless, microUS is not able to provide functional information similar to that provided by microPET. Therefore, microUS and microPET are complementary to each other as microUS has superior spatial resolution and microPET provides functional information, such as hypoxia or necrosis in the progression of the tumor. With image registration and fusion, the combination can be a valuable tool for cancer research.

Abstract:
Microencapsulated phase change materials (MicroPCM) were prepared via sol–gel method using paraffin as heat storage core and silica as inorganic shell. The morphology feature, chemical structure, thermal properties and thermal stability of MicroPCM were characterized by the field emission scanning electron microscope (FE-SEM), Fourier transform infrared spectroscopy (FTIR), the differential scanning calorimeter (DSC), simultaneous thermal analyzer (STA) and the thermal conductivity meter. The results indicated that MicroPCM were spherical in shape with the shell thickness in the range from 236[Formula: see text]nm to 303[Formula: see text]nm. The stirring speed and TEOS dosage were key factor on the latent heat and supercool effect of MicroPCM. The maximum latent heat of MicroPCM was 240.2[Formula: see text][Formula: see text] with the heat loss of only 0.2[Formula: see text][Formula: see text] in phase transformation when it was prepared at the stirring speed of 400[Formula: see text]r/min and TEOS dosage of 20[Formula: see text]ml. MicroPCM was a promising material for thermal energy storage (TES).

Microarc oxidation coatings were prepared on the surface of AZ31 magnesium alloy profiles. Oxidation time of the coatings was between 5min-10min. The phase structure, surface morphology and corrosion resistance of the coatings were investigated using SEM, XRD, copper sulfate spot test and polarization curve test. The results indicate: the main phase compositions of the microarc oxidation coatings are MgO, Mg2SiO4 and MgSiO3; with increasing pulse voltage, the micropore diameter of the coating surface becomes larger, the micropore number reduces and the coating surface roughness increases; the corrosion current density of magnesium alloy reduces significantly after microarc oxidation treatment. The pulse voltage of microarc oxidation should be controlled between 240V-360V to obtain the best corrosion resistance.

Abstract:
The effect of negative pulse voltage on the microstructure and corrosion resistance of microarc oxidation film of A356 aluminum alloy treated by microarc technique was investigated by SEM, coating thickness gauge and electrochemical workstation etc. The results show the negative pulse voltage greatly influences the microstructure and corrosion resistance of microarc oxidation film by its electrode reaction. The film thickness increases while the size of pore and roughness of the film surface decreases initially and then increases with negative pulse voltage increasing. The microarc oxidation treatment considerably improved corrosion resistance, and the highest corrosion potential was -1.16V, which was 0.38V higher than that of substrate, and the corrosion current was lower than that of substrate about three orders of magnitude.

Abstract:
In many branches of science it is important to be able to measure elemental distri­butions on the micrometre level. Therefore a Synchrotron X-ray Fluorescence microbeam has been built at the SRS, Daresbury. The synchrotron microprobe technique for trace element analysis (micro-SXRF) is the subject of this study. This thesis begins with an overview of different microprobe techniques for trace element analysis. Features and capabilities are presented which are used to compare these meth­ods and to make clear the relation between micro-SXRF and the other microprobes. This is followed by a review of relevant literature, which is related to X-ray focussing in gen­eral and the application of synchrotron radiation for trace element analysis, as well as the design and development of synchrotron microbeams. Tools are presented to calculate and judge the quality of optical shapes and configura­tions for the design of X-ray optics. Aberration theory is used to derive the necessary fo­cus conditions as well as the main aberration terms and ray-tracing to design the optical components of the microprobe. The conclusion of the calculations is that in the case of the single crystal option the ellipsoid has the best X-ray optical features. Criteria have been formulated in order to design a microprobe for trace element analysis. Finally an ellipsoidally shaped concave bent Si(lll) crystal has been constructed as the basic element of the microprobe. The results are presented in terms of beam profiles and flux densities to demonstrate the focussing action of the bent crystal and in terms of de­tection limits and sensitivities to demonstrate the analytical features, which are consis­tent with calculations. A final resolution of 10x15 pm2 is obtained and a flux density of about 104 ph/(s.mA.pm2) is measured for 15 keV quasi-monochromatic radiation, which is able to detect femtogram levels in favourable cases. The last part of this study is devoted to the design of X-ray optics for the ESRF (Greno­ble). Comparisons are made for what can be expected if the ESRF source parameters are used rather than the SRS source parameters for the same type of optics. A planar-ellip­soid combination seems to be a good option for focussing as well as managing the high intensity of the incident white beam.

Abstract:
Neste trabalho apresentamos o projeto do microtron principal do IFUSP. Inicialmente são apresentados os fundamentos teóricos relativos à estabilidade do feixe em um microtron, bem como discussões sobre a ótica do feixe. No trabalho são feitas basicamente 3 tipos de simulações distintas: simulação da dinâmica longitudinal e transversal da etapa síncrona, simulação da dinâmica transversal das linhas de transferência (inserção e extração) e a simulação relativa à otimização do projeto dos eletroímãs principais. As simulações longitudinais mostraram que é possível reduzir a energia de entrada do microtron principal de 4,9 para 2,5 MeV, o que permitira a eliminação do primeiro estágio síncrono (microtron booster). A energia final do microtron principal passa a ser 38 MeV. Foram realizados os projetos de duas linhas de inserção no principal para essas as duas energias (2,5 e 4,9 MeV) e foi feita uma análise comparativa desses dois projetos. O projeto da linha de extração também foi analisado levando em consideração duas energias de extração (5,8 e 38 MeV) para se mostrar a viabilidade dessa etapa.
In this work we present the design of the IFUSP main microtron. Initially, the theoretical foundations for the beam stability in the microton are presented as well as the beam optics is discussed. Three different kinds of simulations were done: Longitudinal and transversal beam dynamics in the synchronous part of the machine, transversal beam dynamics concerning the transfer lines and simulations related to the design of the main magnets. The longitudinal simulations sugested that it is possible to reduce the initial energy of the main microtron from 4.9 to 2.5 MeV, this would permit the elimination of the first synchronous stage (booster microtron). The final energy of the main microtron will be 38 MeV. The design of two insertion lines in the main microtron for the two different energies (2.5 and 4.9 MeV) was done and a comparative analysis between these two designes is presented. The design of the extraction line also takes into account two different extraction energies (5.8 and 38 MeV) in order to show de viability of this part.

Abstract:
Les plaquettes jouent un rôle majeur dans le maintien de l’hémostase, ainsi que dans les phénomènes de thrombose et d’occlusion vasculaire. Elles ne contiennent pas d’ADN génomique, mais recèlent néanmoins un transcriptome complexe. Bien que les ARN messagers (ARNm) plaquettaires peuvent être traduits de novo, notamment en réponse aux stimuli physiologiques, les mécanismes contrôlant cette synthèse demeurent obscurs. Notre équipe a démontré que les plaquettes humaines contiennent une quantité abondante et diversifiée de microARN, suggérant leur implication dans le contrôle de la traduction des ARNm plaquettaires. Suite à une stimulation, les plaquettes libèrent des microparticules (MP), qui permettent de véhiculer des signaux biologiques, dont du matériel génétique, à des cellules réceptrices. L’implication des microARN plaquettaires dans la communication intercellulaire via les MP reste à être approfondie. Mes travaux de doctorat, portant sur l'étude des complexes ribonucléoprotéiques au sein des plaquettes, ont montré l’implication des microARN et de la protéine T-cell-restricted intracellular antigen-1 (TIA-1) dans la reconnaissance et la régulation des ARNm plaquettaires, apportant ainsi de nouvelles connaissances sur les mécanismes moléculaires impliqués dans la régulation de la synthèse protéique de novo suite à l’activation des plaquettes. De plus, l’étude de la communication intercellulaire entre les plaquettes et les macrophages a permis de montrer que les MP plaquettaires (i) livrent des microARN aptes à réguler l’expression d’ARNm endogènes chez les cellules réceptrices, et (ii) reprogramment les fonctions primaires des macrophages, laissant entrevoir de nombreuses implications physiologiques. Les résultats de ma thèse suggèrent que les microARN plaquettaires contribuent au maintien de l’hémostase, en participant à la régulation de la synthèse protéique des plaquettes et en modulant l’expression génique des cellules environnantes. L’étude de la fonction des microARN plaquettaires a permis de mettre en relief la complexité de la régulation de l’hémostase et du système circulatoire.
Platelets play an important role in hemostasis, as well as in thrombosis and coagulation processes. Lacking genomic DNA, they nevertheless harbor a complex transcriptome. Although platelet messenger RNAs (mRNAs) can be used for de novo protein synthesis, especially in response to physiological stimuli, mechanisms controlling this synthesis remain unclear. Our team demonstrated that human platelets contain an abundant and diverse array of microRNAs, suggesting their involvement in the control of platelet mRNA translation. Following stimulation, platelets release microparticles (MPs) that convey biological signals and genetic material to recipient cells. The involvement of platelet microRNAs in the intercellular communication via MPs remained incompletely understood. The study of microRNA-containing ribonucleoprotein complexes inside platelets revealed the involvement of microRNAs and of the protein T-cell-restricted intracellular antigen-1 (TIA-1) in the recognition and regulation of platelets mRNAs, thereby improving our understanding of the molecular mechanisms regulating de novo protein synthesis upon platelet activation. Moreover, the study of intercellular communication between platelets and macrophages demonstrated that platelet MPs could (i) deliver functional microRNAs capable to regulate endogenous mRNA expression in recipient cells, and (ii) reprogram primary functions of macrophages, suggesting numerous physiological effects. My thesis results suggest that platelet microRNAs contribute to maintain the hemostatic balance, in regulating the synthesis of essential proteins and by modulating gene expression of surrounding cells. The study of platelet microRNA functions underscores the complexity of the regulatory processes of hemostasis and of the circulatory system.

Abstract:
This thesis is concerned with the application of Laser Microprobe Mass Spectrometry (LAMMS) to the microanalysis of inorganic materials and in particular to the quantification of such analyses. The investigation consists both of an assessment of the capabilities of a LAMMS instrument, the Cambridge Mass Spectrometry LIMA 2A, and an attempt to correlate experimental results with theoretical predictions. The principles of the operation of a LAMMS instrument are discussed and a description of the LIMA 2A instrument is presented. A survey of the literature concerned with the interaction of a high-powered laser with a solid specimen to produce a plasma, the basis of the LAMMS technique, is included. Particular emphasis is given to the description of this interaction in terms of a model based on a local thermodynamic equilibrium (LTE) in the plasma. This model is applied to the conditions estimated to be produced in the LIMA instrument to make simple predictions of expected results. A discussion of the possible methods for converting LAMMS data into a quantitative analysis is given, along with a brief description of the statistical techniques used for data handling. Several model materials, principally chosen for their well-defined composition and known lateral homogeneity, are used in this work. These are single-crystal silicon, a binary copper-nickel alloy and three III-V semiconductors drawn from the Ga-In-As system. The effect of the instrument itself is investigated, with a view to establishing its contribution to the errors observed in the data. This is followed by an investigation of the variation of both the absolute and relative ion signals produced. The variations in the relative ion signals are then compared with the predictions of the LTE model in an attempt to establish its validity. This comparison is also used to estimate the conditions produced in the laser-induced plasma and their variation with specimen chemistry and laser power density. The general conclusions of the investigation are drawn together in a discussion of the preferred methods for the quantification of LAMMS data and the expected error in the resulting analysis. It is shown that, provided appropriate methods are used, the LAMMS technique can provide quantitative analyses with precisions of about 5-20%.

Abstract:
Various approaches have been investigated for micropart (∼250 μm in size) manipulation especially for their controlled positioning for automated assembly of MEMS devices. The motion dynamics of a micropart in a dry-friction environment due to controlled deformation of a continuous flexible surface have been developed and are used to study the sensitivity of micropart motion and micropositioning as function of micropart and surface material properties and input actuator properties. The dynamics consider Van der Waal’s forces, effects of surface deformation profile, relative surface roughness, the dynamic compression of asperities and their effect on the dynamic friction coefficient based on extending Kogut-Etsion friction model through a quasi-dynamic coefficient of friction estimation. The motion of the micropart is affected by these parameters, and it is found that for some combinations of parameters a range exists that could cause motion while outside this range either there is no motion or the micropart detaches from the surface. The understanding of the effects of these parameters on micropart motion could pave the way towards controlled micropart translocation and manipulation employing a continuous flexible surface for microassembly, processes requiring controlled micropart handling for homogeneous or heterogeneous microdevice mass production, or for the development of microconveyor systems.

Abstract:
A fluidic experimentation platform, consisting of a piezoelectrically driven microdrop generator which is mounted on a quick-action clamping device, is introduced. Microdrop generators are playing an increasingly important role in many industries. Even though their beginnings were in the printing and coating sector, their strengths are more and more used in other sectors. The wide variety of properties of the fluids like molten polymers, dispersions, or monomers usually require a redesign of the microdrop generator for each application to achieve drops of the size, with the speed, and uniformity that are needed. Therefore, the use of rapid prototyping (RP) techniques for the adaption of microdrop generators to new boundary conditions is indispensable. The presented microdrop generator is based on the diaphragm design. A silicon base plate includes the fluidic components. The number of nozzles is three. Even if one nozzle is clogged two other nozzles are working. The diaphragm is made of borosilicate glass. On top of the diaphragm a piezoelectric transducer is glued. The piezoelectric transducer and the diaphragm form a bimorph actuator. Since only the borosilicate glass and the silicon are in contact with the fluid the assembly is highly chemical resistant to aggressive media. Thus, a very broad range of fluids is ejectable. Besides the laser as main tool a dicing saw is involved in the process flow. Investigations for the optimum machining parameters are presented. In this project four equal microdrop generators respectively 12 nozzles and one further silicon base plate for further quality inspection of the whole batch are manufactured simultaneously. They serve as a good basis for fluidic experiments. Only six process steps are necessary to fabricate one microdrop generator within 25 min. Up to 16 microdrop generators can be batch fabricated in a 4″ process chain with rapid prototyping techniques. The realized quick-action clamping device supports a rapid exchange of the microdrop generators and enables future technologies. Here, the electrical and the fluidic connection of the microdrop generator are realized. The microdrop generator is inserted into a groove and is at the same time fluidically and electrically connected via four spring contacts. Special feature is that no gluing or soldering processes are necessary. The device is constructed in a modular way to add further components like a heating cartridge or a fluid reservoir. Overall, the exchange of one microdrop generator can be realized within one minute. The use of the batch fabricated microdrop generator in combination with the presented quick-action clamping device guarantees an efficient execution of fluidic experiments.

Abstract:
In this study, we examine an efficient method for fabricating microrods with high accuracy, using a cutting process. Two problems exist in the fabrication of microrods using the cutting process. The first problem is low processing accuracy due to microrod deflection resulting from the cutting force acting during the process and microrod breakage at the end of the process. The second problem is deterioration of the cut surface due to low cutting speed resulting from the small diameter of the microrod. We propose the following methods to solve these problems. For the first problem, we propose a cutting method that uses a cutting-tool path and cutting sequence to achieve a minimum cutting force acting on the microrod during the process. For the second problem, we propose a cutting method that uses ultrasonic vibration to decrease the cutting force, thereby realizing good cutting surfaces under the low-cutting-speed condition. As a result, we succeeded in the fabrication of a linear microrod with a 50 μm diameter and an aspect ratio of 100, as well as a microrod for a friction wheel with a complex stepped shape of 70 μm minimum diameter. Thus, we demonstrated the effectiveness of the proposed cutting method for microrods.

Abstract:
Abstract Owing to the wide applications in a large variety of multi-disciplinary areas, electrowetting-based digital microfluidics (DMF) has received considerable attention in the last decade. However, because of the complexity involved in the droplet generation process, the techniques and configurations for precise and controllable microdrop generation are still unclear. In this paper, a numerical study has been performed to investigate the impact of electrode arrangements on microdrop generation in an electrowetting-based DMF Platform proposed by a previously published experimental work. The governing equations for the microfluidic flow are solved by a finite volume formulation with a two-step projection method on a fixed numerical domain. The free surface of the microdrop is tracked by a coupled level-set and volume-of-fluid (CLSVOF) method, and the surface tension at the free surface is computed by the continuum surface force (CSF) scheme. A simplified viscous force scheme based on the ‘Hele-Shaw cell’ model is adopted to evaluate the viscous force exerted by the parallel plates. The generation process has been simulated with three different electrode arrangements, namely, ‘SL’, ‘SW’, and ‘SQ’. The effect of electrode arrangement on microdrop volume has been investigated. Besides, the influences of the initial microdrop location and volume on the generation process for the ‘SL’ design have been studied. The results can be used to advance microdrop generation techniques for various electrowetting-based DMF applications.

Full text
Abstract:
Use of microencapsulated phase change material (microPCM) in a single phase carrier of fluid for enhanced cooling has been demonstrated by many researchers for the case of laminar flow. However, very little is known about the behavior of microPCM fluids for turbulent flows. Here we consider the flow of octacosane microPCMs in a 50/50 by volume ethylene glycol/water carrier fluid. This high temperature microPCM fluid, with Tmelt = 60°C, has a much lower viscosity than room temperature microPCM fluids. Room temperature microPCMs in 50/50 by weight ethylene glycol/water carrier fluid generally operate at Reynolds numbers much below the critical value due to their large viscosity and the unreasonably large pumping power required to produce turbulent flow. At 60°C, however, the flow can become transitional and perhaps fully turbulent with moderate pressure rise pumps. This paper presents the performance of an octacosane based microPCM fluid operating in the transitional region at Reynolds numbers up to 2900. Transitional flow convective heat transfer coefficients are shown to be as much as 50% higher than laminar flow values. In addition, surface temperatures are reduced with increasing Reynolds number.

Abstract:
Electrical coupling in microgyro is an important phenomenon which can affect its performance and reliability. The objective of this study was to characterize the influence of leakage voltages on microgyro performance. The study was performed with a vibrating microgyro, which is based on electrostatic actuation and optical sensing, and fabricated by bulk micromachining of SOI wafers. Two parameters were measured in this study: (1) amplitude ratio between leakage voltage measured on the sense pads and actuation voltage applied to the actuation pads and (2) phase shift of those voltages. It is found that the net electrostatic force exerted on the sense masses of the microgyro is quite small due to symmetry of the leakage voltages. Hence, the corresponding displacement is negligible small. Frequency dependency of the leakage voltages and resulting electrical coupling is considered as one of the mechanisms for bias short term instability and estimated to be less than 1°/hr.
