Abstract (sommario):

In this study, Cd2SnO4 nanoparticles were produced using a sol-gel technique. X-ray diffraction was used to investigate the Cd2SnO4 nanoparticles. Transmission electron microscope (TEM) with Fourier transform infrared spectrophotometer (FTIR), FE-SEM images show that manufactured Cd2SnO4 nanoparticles have cubic structures with some irregular cubic shaped nanoparticles. XRD patterns of the prepared thin films showed that the nanoparticles have a polycrystalline structure. The wide bands between 551 and 854 cm-1 are attributable to the framework vibrations of the Sn-O bond in SnO2, and the band at 551 cm-1 is also due to cadmium and oxygen in this area, according to the FTIR analysis. The TEM result shows the presence of cubic shaped nanoparticles. The interaction between the cadmium nanoparticles and the cellular contents of the fungi may be the reason for the antifungal effectiveness of Cd2SnO4 nanocomposites.

Abstract (sommario):

Abstract Ceramic membranes are considered superior over their polymeric counterparts for applications at high temperature, pressure, and in aggressive environments with additional advantages of cleaning at high temperature. Preparation of porous ceramic membrane is expensive because the ceramic materials cannot be processed in a liquid state as polymers. Ceramic membrane synthesis involved solid powder preparation, consolidation, suspension formation, calcination, and sintering temperature which makes its synthesis very expensive. Geopolymerization is a heterogeneous reaction of aluminosilicate materials and chemical activators to form a three-dimensional structure having high mechanical strength without sintering. The overall percent energy and cost-saving of geopolymeric membranes were compared with conventional ceramic membranes. Recently, the geopolymerization technique has been used for membrane synthesis to replace conventional ceramic membrane synthesis. The objective of this review article is to discuss the potential opportunities and challenges in the synthesis and application of geopolymeric membranes.

Abstract (sommario):

The aim of this thesis was to synthesise CoAPO-34 and FeAPO-34 using ionothermal synthesis in the presence of organic amines. Using this method provides an alternative route to prepare such materials under low pressure instead of the higher pressure associated with hydrothermal or solvothermal synthesis. Both materials have chabazite (CHA) topology and they are known to act as catalysts. CoAPO-34 was ionothermally prepared using 1-ethyl-3-methylimidazolium bromide (EMIMBr) in presence of 1, 6-hexadiamine (HDA). This study has found that when the synthesis was carried out without HDA, AlPO-11 was preferentially obtained instead of CoAPO-34. Broad line signals which appear between 2000 to 5000 ppm in both spin-echo ³¹P NMR spectra of as-synthesised and calcined CoAPO-34 confirm that the Co²⁺ ions have been successfully incorporated within the framework of the material. FeAPO-34 was synthesised under ionothermal conditions using 1-ethyl-3-methylimidazolium chloride in the presence of ethylenediamine (EDA). In the absence of EDA, the synthesis has produced AlPO-34 instead of FeAPO-34. Broad line signals that appear between 1000 to 14000 ppm in spin-echo ³¹P NMR spectra of both as-synthesised and calcined FeAPO-34 are direct evidence of isomorphous substitution of framework aluminum by Fe(II) or Fe(III). Another aim of this study was to explore the ionothermal synthesis of copper containing aluminophoshate of DNL-1 (Cu/DNL-1). This material was attractive to explore because it contains 20 ring extra-large pores and Cu(I) species in the channels of the framework, potentially giving material the ability to simultaneous store NO and to generate NO from NO₂⁻ anions. Cu/DNL-1 was successfully prepared under ionothermal conditions using EMIMBr and HDA. Without HDA in the synthesis, AlPO-11 was obtained. In this material, copper ions were not incorporated in the Cu/DNL-1 skeleton framework. This was confirmed by absence of broadline signal at >500 ppm in spin-echo ³¹P NMR spectrum of the sample. The copper ions are expected to be present as extra-framework cations. Extra-framework Cu(I) species that were formed by high temperature calcination of Cu/DNL-1 are active to produce NO from NO₂⁻. Therefore, the calcined Cu/DNL-1 can be used to simultaneously store and produce NO from nitrite. This has the potential to signiﬁcantly extend the lifetime of gas delivery in the material to prevent thrombus formation.

Abstract (sommario):

This thesis aims to investigate structural, optical and photoelectrochemical behavior of CdS nanowires and their heterojunctions with CdTe and polypyrrole nanowires. In the first part, CdS nanowires have been synthesized via electrochemical template-based route. It has been observed that synthesis conditions, such as bias voltage and deposition time, affect the morphology, optical and photoelectrochemical characteristics of CdS nanowires. Depending on the deposition time, length of the CdS nanowires changed from 100-200 nm to 3-4 m. Also the diameter of the nanowires increased with increasing the deposition time. Structure of the CdS nanowires has been confirmed by X-ray diffraction spectrometry and EDX analysis. Phototelectrochemical performances of the CdS nanowires have been changed dramatically with bias voltage and deposition time.In the second part of this thesis, CdTe nanostructures have been deposited on CdS nanowires. Change in optical and photoelectrochemical behavior of CdS nanowires after CdTe deposition has been investigated. Organic semiconductors and their composites with inorganic materials have been gaining attention due to tunable optical, electrical and magnetic properties. Also, ease of fabrication techniques, and therefore, low cost made these materials attractive for lots of applications including photovoltaic devices and flexible electronics. In the last part of this thesis, heterojunctions of CdS and Polypyrrole (Ppy) nanowires have been synthesized. Like CdS/CdTe heteronanostructures, first the CdS nanowires have been electrochemically deposited in anodized alumina template and then Ppy has been successfully deposited on CdS nanowires. In order to investigate the effects of polypyrrole synthesis conditions on CdS/Ppy heteronanostructures, CdS nanowire synthesis conditions have been kept constant. It has been observed that morphology and photoelectrochemical behavior of the Ppy nanowires has been affected from Ppy synthesis conditions. The photoelectrochemical performance changes of CdS/Ppy heteronanostructures have been also investigated in this part.

Testo completo

Abstract (sommario):

Printed lens antennas offer the possibility of realizing shaped beam patterns using no more complexity than is required for pencil beam patterns. Shaped beam patterns can be obtained by appropriately determining the complex transmission coefficient required for each cell (or element) of the printed lens, taking into account the varying feed field over the input surface of the lens. Certain ranges of transmission coefficient amplitude and phase are undesirable (eg. too low an amplitude implies a large reflection at the lens input surface). It would be preferable to constrain the range of values that the transmission coefficient can take as an integral part of the lens synthesis procedure, and thus the transmission coefficient itself needs to be the synthesis variable. In this thesis a synthesis technique for doing this is developed based on the method of generalized projections, modified to “operate” in the space of transmission coefficients. This makes it possible to immediately perceive what influence constraints on the actual transmission coefficients have on the possible radiation pattern performance. In addition, an approach that allows one to constrain the transmission coefficient to values that must be selected from an available database of transmission coefficients is incorporated into the synthesis technique.

Abstract (sommario):

In the name of scholarship, there has been a tendency to either downplay or ignore all together the emotional aspects that are often the driving force of creative undertakings. One does not have to do this with the music of Brahms, because expression and technique are not mutually exclusive. This study examined the integral connection between personal experience, text and music that is demonstrated so uniquely and emphatically in the Alto Rhapsody. The study began with a description of key events that shaped the musical and personal life of the composer: from the launching of his career in 1853 to the writing of his Alto Rhapsody in 1869. Brahms's relationship to the text of the Rhapsody, three central stanzas from Goethe's Harzreise im Winter, was discussed. The music was analyzed under the categories of formal design, texture, and motion. Each category featured a comparison between the Brahms setting and the earlier one which inspired it: Johann Friedrich Reichardt's 1790 version. Analysis of the formal design began by weighing the personal factors that influenced the two Rhapsodies . The means by which vocal and instrumental textures were used to enhance textual meaning were evaluated. The musical analysis concluded with a description of rhythmic, melodic and harmonic motion employed in the Alto Rhapsody. Viewed as a synthesis of personal experience, text and music, the Alto Rhapsody provided a unique opportunity to gain insight into various features of the composer and his art. This study explored the aspects of contrast, balance and emotional expression. Analysis of Brahms's Alto Rhapsody revealed significant relationships between the composer, his chosen text and the musical materials and methods used to compose the work. An understanding of these relationships can serve as the basis for informed interpretation, effective rehearsal and expressive performance.

Ledwell, Paul H. "A synthesis of form, color, and content in relief sculpture". Virtual Press, 1989. http://liblink.bsu.edu/uhtbin/catkey/724972.

Testo completo

Abstract (sommario):

The successful combination of form, color, and content prior to the relief construction movement in the 1960's was usually associated with two-dimensional artwork. The problem, then was whether the artist could successfully combine form, color, and content in three-dimensional sculpture pieces.The content of the work described relates to the artist's personal experiences as an underground uranium miner through the medium of relief sculpture. The successful combination of form, color, and content conveyed the artist's mining experiences to a neophyte audience. The visual variety and motif in the work, however, will not be lost on any members of the audience who are also sculptors.The methods used by the artist included textbook research and studio experimentation to produce a series of pieces which would address the successful combination of form, color, and content. The research also included a study of other artists' use of shape and color in the relief sculpture format. The artist's findings were documented in the form of a thesis paper and also eight relief sculpture pieces which employed a combination of wood and paint. The paint was applied to the wood structure using a heavy impasto technique which completely obscures the wood and allows the artist to manipulate both form and color. The texture invites the viewer to explore the surface and shapes without consciously sorting out what materials are used in the construction of the sculpture.

Meng, Xiangjun. "A synthesis technique for radial line slot array antennas with isoflux radiation patterns". Thesis, University of Ottawa (Canada), 2009. http://hdl.handle.net/10393/28325.

Testo completo

Abstract (sommario):

In this thesis the possibility of using radial line slot array (RLSA) antennas to provide low profile isoflux radiation patterns suitable for use as circularly-polarized tracking, telemetry & command (TT&C) antennas on low Earth orbit (LEO) satellites is investigated. The RLSA antenna elements are slot pairs located on concentric circles on the top plate of a radial waveguide. Conventional synthesis techniques cannot be used due to the fact that the RLSA antenna is a non-uniformly spaced array, the elements do not all have the same orientation, and the excitation amplitudes and phases are linked to the actual physical location of a particular slot pair. A technique is therefore developed for synthesizing such an RLSA antenna. Keywords: Antennas, Radial Line Slot Antennas, Isoflux Radiation Patterns

Abstract (sommario):

Graphical and analytical syntheses have been well applied to path, motion and function generation of planar mechanisms. Optimization techniques in common, require “good initial guesses” and do not necessarily converge to a solution. This paper presents a methodology to synthesize mechanisms employing an evolutionary optimization approach technique known as Differential Evolution. The initial bounds for the design variables are defined automatically using a newly developed and novel technique called the Geometric Centroid of Precision Points. Optimum synthesis of four-bar linkages for path generation with user defined accuracy level at required precision points is discussed.

Testo completo

Abstract (sommario):

A main topic of inverse problems in crystallography appears to have been phase recovery of diffracted fields in diffraction crystallography1,2. In this paper we deal with a problem of detecting yet another type of phase in a structure image (or a lattice fringe image) obtained by the direct observation of a crystal using a high-resolution electron microscope. The phase in our problem represents spatial distortion of lattices in a crystal rather than the phase of X-ray or electron wave fields. We note that a quasi periodic structure of atoms observed in a TEM (transmission electron microscopy) image or in a STM (scanning tunnel microscopy) image bears a close similarity to an optical interferometric fringe pattern having spatial carrier frequencies, where lattice distortion or atom displacement may be regarded as a spatial fringe shift. The interpretation of the distorted lattice image as an interferogram permits us the use of spatial heterodyne technique for highly sensitive detection of the lattice distortion, where a phase change by 2π corresponds to the displacement of an atom by a lattice constant. Based on this interpretation, we propose a crystallographic heterodyne technique for precisely determining the positions of dislocated atoms using the Fourier fringe analysis technique originally developed for optical heterodyne interferometry3,4.

Testo completo

Abstract (sommario):

The idea behind the method of constrained image restoration by compensating the point spread function (PSF) is to obtain a restoration filter such that when it is convolved with the PSF the resulting function, called the composite point spread function (CPSF), satisfies appropriate optimization criteria. Ideally it would be desirable to obtain a CPSF that is a delta function; i.e., the restoration filter would be the inverse filter. However this is not possible due to the instability and serious noise amplification of such filters. Stable filters using this approach can be obtained by minimizing an appropriate width measure while constraining the output noise power [1-3]. There are significant advantages in using this method for image (or signal) restoration over other commonly employed procedures. First, the restoration operator can be constrained to a specific size, thereby controlling the duration of transients due to edge effects and reducing the computational burden. Second, the procedure is not dependent on statistics of the image but only on the sensor PSF, the noise, and the sampling grid. Third, for image enhancement it is possible to combine the interpolation and deconvolution procedures into a single operation, thereby increasing the speed and efficiency of the processing.

Abstract (sommario):

Frequency-resolved optical gating[1, 2] (FROG) is a technique that uses a phase-retrieval algorithm to obtain the intensity, I(t), and phase, ϕ(t), from a measured spectrogram of the pulse. Previous simulations have shown that, for noise-free data, the algorithm retrieves the correct intensity and phase for all pulses attempted, including those with complex intensity and phase structure. In practice, however, noise is present in actual FROG traces, and here we discuss the effects of noise on FROG and image-processing techniques to improve the retrieval.

Abstract (sommario):

Project Title: "Development of a plasmid-based reverse genetics system for the Bluetongue and Epizootic Hemorrhagic Disease viruses to allow comparative characterization of the function of the NS3 viroporin in viral egress". Project details: No - IS-4192-09; Participants – Ehrlich M. (Tel Aviv University), Parker J.S. (Cornell University), DermodyT.S. (Vanderbilt University); Period - 2009-2013. Orbiviruses are insect-borne infectious agents of ruminants that cause diseases with considerable economical impact in Israel and the United States. The recent outbreaks of BTV in Europe and of Epizootic Hemorrhagic Disease Virus (EHDV) in Israel, underscore the need for: (i) a better comprehension of the infection process of orbiviruses, (ii) the identification of unique vs. common traits among different orbiviruses, (iii) the development of novel diagnosis and treatment techniques and approaches; all aimed at the achievement of more effective control and treatment measures. It is the context of these broad goals that the present project was carried out. To fulfill our long-term goal of identifying specific viral determinants of virulence, growth, and transmission of the orbiviruses, we proposed to: (i) develop reverse genetics systems for BTV and EHDV2-Ibaraki; and (ii) identify the molecular determinants of the NS3 nonstructural protein related to viroporin/viral egress activities. The first objective was pursued with a two-pronged approach: (i) development of a plasmid-based reverse genetics system for BTV-17, and (ii) development of an "in-vitro" transcription-based reverse genetics system for EHDV2-Ibaraki. Both approaches encountered technical problems that hampered their achievement. However, dissection of the possible causes of the failure to achieve viral spread of EHDV2-Ibaraki, following the transfection of in-vitro transcribed genomic segments of the virus, revealed a novel characteristic of EHDV2-Ibaraki infection: an uncharacteristically low fold increase in titer upon infection of different cell models. To address the function and regulation of NS3 we employed the following approaches: (i) development (together with Anima Cell Metrology) of a novel technique (based on the transfection of fluorescently-labeledtRNAs) that allows for the detection of the levels of synthesis of individual viral proteins (i.e. NS3) in single cells; (ii) development of a siRNA-mediated knockdown approach for the reduction in levels of expression of NS3 in EHDV2-Ibaraki infected cells; (iii) biochemical and microscopy-based analysis of the localization, levels and post-translational modifications of NS3 in infected cells. In addition, we identified the altered regulation and spatial compartmentalization of protein synthesis in cells infected with EHDV2-Ibaraki or the mammalian reovirus. In EHDV2-Ibaraki-infected cells such altered regulation in protein synthesis occurs in the context of a cell stress reponse that includes the induction of apoptosis, autophagy and activation of the stressrelated kinase c-Jun N-terminal Kinase (JNK). Interestingly, inhibition of such stress-related cellular processes diminishes the production of infectious virions, suggesting that EHDV usurps these responses for the benefit of efficient infection. Taken together, while the present project fell short of the generation of novel reverse genetics systems for orbiviruses, the development of novel experimental approaches and techniques, and their employment in the analysis of EHDV-infected cells, yielded novel insights in the interactions of orbiviruses with mammalian cells.
