The use of postharvest irradiation to improve colour has been successful on apples, and the objectives of this thesis were to optimise conditions during irradiation for apples and to evaluate the effects of irradiation on pears. 'Cripp's Pink' apples responded to postharvest irradiation with high-pressure sodium (HPS) lights by developing a red blush, whereas the response to irradiation with UV 8 plus incandescent lights was less effective. '8raeburn' apples held at -0.5°C for 4 or 8 weeks prior to irradiation showed a decrease in hue angle and an increase in anthocyanin concentration after 72 hours of irradiation with HPS lamps. In 'Forelle' pears treated in the same way, neither colour development nor anthocyanin synthesis was affected by irradiation. '8raeburn' and 'Cripp's Pink' apples picked weekly for 5 weeks until the optimum harvest date were irradiated with HPS lights. A significant increase in fruit colour was only measured in mature fruit of both cultivars. 'Cripp's Pink' apples were harvested from two production areas with different microclimates, namely, Ceres and Grabouw, and stored for 0, 2 or 5 days at -0.5 °C before irradiation for 120 hours at either 6°C or 20°C. Fruit from Ceres that were irradiated immediately after harvest developed better colour at 6 °C than at 20°C. The differences between fruit irradiated at the two temperatures were no longer significant after 5 days of cold storage prior to irradiation. Fruit from Grabouw consistently developed better colour when irradiated at 6°C than at 20°C. Colour development slightly after 5 days of cold storage prior to irradiation. In another experiment, fruit from both areas were stored at -0.5°C for 20 days before irradiation at either 6°C or 6/20°C. The fluctuating temperature regime resulted in decreases in hue angle of 70° and 65° for the fruit from Grabouw and Ceres, respectively. The decreases were smaller (±200) when fruit were irradiated at 6°C. The hue angle value of well-coloured 'Cripp's Pink' apples held at 3rC under HPS lights for 144 hours increased from 29.3° to 48.3°, and anthocyanin concentration decreased from 739.9 IJg·g·1to 283.6 IJg·g·1. Control fruit held at the same temperature in the dark did not show any change in hue angle value or anthocyanin concentration. 'Bon Rouge' and 'Red d' Anjou', two full red pear cultivars, irradiated with HPS lights for 72 hours, showed no significant changes in hue angle. 'Forelle' pears, harvested with or without attached leaves, were irradiated with HPS at two temperature regimes, 20°C and 200/6°C. The resulting decreases in hue angle were attributed to yellowing and not red colour formation. In conclusion, the response of apples to postharvest irradiation was affected by maturity and temperature, while pears failed to respond at all.
AFRIKAANSE OPSOMMING: Rooikleurontwikkeling van twee-kleur appels en pere verseker beter pryse vir die produsente. Na-oesbestraling om kleur te verbeter is al suksesvol uitgevoer op appels, en die doelwit van hierdie tesis was om die kondisies vir appels gedurende bestraling te optimaliseer en om die effek van bestraling op pere te evalueer. 'Cripp's Pink' appels het reageer op na-oesbestraling met hoëdruk-natriumligte (HDN) deur 'n rooi blos te ontwikkel, terwyl die reaksie op bestraling met UV-B plus gloeilamplig minder effektief was. 'Braebum' appels opgeberg by -O.5aC vir 4 of 8 weke voor bestraling het 'n afname in die kleurskakeringswaarde getoon, asook 'n toename in antosianienkonsentrasie na 72 uur se bestraling met HDN ligte. 'Forelle' pere wat dieselfde behandeling ontvang het, het geen kleurontwikkeling en geen antosianienontwikkeling getoon na bestraling nie. 'Braebum' en 'Cripp's Pink' appels wat weekliks geoes is vir 5 weke tot die optimum oesdatum is bestraal met HDN ligte. Slegs die volwasse vrugte van beide kultivars het 'n betekenisvolle toename in kleur getoon. 'Cripp's Pink' appels is geoes in twee produksie areas met verskillende mikroklimate, naamlik Ceres en Grabouw. Vrugte is opgeberg vir 0, 2 of 5 dae by -O.5aC voor bestraling vir 120 uur by of 6aC of 20aC. Vrugte van Ceres wat onmiddellik na oes bestraal is het beter kleur ontwikkel by 6aC as by 20aC. Kleurontwikkeling by vrugte bestraal by 6 of 20aC het nie verskil wanneer vrugte vooraf opgeberg was by -~5ac vir 5 dae nie. Vrugte van Grabouw het konstant beter kleur pntwikkel wanneer bestraling by 6°C eerder as 20°C plaasgevind het. In die volgende eksperiment, was beide die vrugte van Ceres en Grabouw vir 20 dae opgeberg by -o.soC voor bestraling by 6°C of 6°/20°C. Die flukturerende temperatuur regime het afnames van 70° en 65° in kleurskakeringswaarde getoon vir die vrugte van Grabouw en Ceres, respektiewelik. Die afname was kleiner (±200)wanneer vrugte by 6°C bestraal is. 'Cripp's Pink' appels wat goed gekleur was en opgeberg is by 3rC terwyl dit blootgestel is aan HDN ligte vir 144 uur, het 'n toename van 29.30 tot 48.3° getoon vir die kleurskakeringswaarde, en antosianienkonsentrasie het afgeneem van 739 I'g.g-1 tot 283.6 I1g.g-1. Die kontrole vrugte opgeberg by dieselfde temperatuur in die donker het geen verandering in beide die kleurskakeringswaarde of die antosianienkonsentrasie getoon nie. 'Bon Rouge' en 'Red d' Anjou', twee volrooi peerkultivars, is bestraal met HDN ligte vir 72 uur en het geen betekenisvolle verandering in kleur getoon nie. 'Forelle' pere, geoes met of sonder 'n aangehegte stingelsegment, is bestraal met HDN ligte by twee verskillende temperatuur regimes, nl. 20°C of 20/6°C. Die afname in kleurskakeringswaarde is aan vergeling toegeskryf eerder as aan rooikleurontwikkeling. Ter opsomming, die reaksie van appels op na-oes bestraling is beïnvloed deur rypheid en temperatuur, terwyl pere geen reaksie getoon het nie.

Повний текст джерелаUnder certain South African conditions, Redglobe develops a colour that is too dark and thus unacceptable for the Far Eastern markets. These markets require a pink colour instead of a dark red colour. The cultivation of grapes with an acceptable colour involves amongst other, canopy management practices. This generally includes the removal of leaves and/or lateral shoots. Hereby, the leaf area and the microclimatic conditions in the canopy are altered. The aim of this study was to test the usefulness of leaf and lateral shoot removal at different defoliation times after anthesis in order to obtain a pink coloured Redglobe crop. Other quality aspects, namely total soluble solids (TSS), total titratable acidity (TTA), berry mass and total yield, were also evaluated. A canopy management trial was conducted on six year old Redglobe vines with moderate vigour. The treatment design was a 2 x 3 x 4 factorial and involved two leaf removal (L) levels (L0 = 0% leaf removal; L33 = 33% leaf removal) in combination with three lateral shoot removal (LS) levels (LS0 = 0 % lateral shoot removal; LS50 = 50% lateral shoot removal; LS100 = 100% lateral shoot removal). Four defoliation times (DT) were selected: 36 (pea berry size), 69 (véraison), 76 (one week after véraison) and 83 (two weeks after véraison) days after anthesis (DAA). A total of 24 treatment combinations, replicated in four blocks, were applied. Generally, treatment combinations involving 33% leaf removal lowered the main shoot leaf area. Likewise, the lateral shoot leaf area was decreased by increasing levels of lateral shoot removal at any defoliation time. As expected, 33% leaf removal applied in combination with any level of lateral shoot removal, always resulted in a lower total vine leaf area compared to where 0% leaf removal was part of the treatment combination. Compensation reactions occurred and in this regard the main shoot leaf size increased due to 33% leaf removal applied at 1 week after véraison and 2 weeks after véraison. Treatment combinations involving lateral shoot removal increased the ratio of main shoot leaf area to the total leaf area. On the other hand, the main shoot leaf area percentage was lowered by the application of 33% leaf removal at 2 weeks after véraison compared to no leaf removal at the same defoliation time. It can therefore be assumed that the contribution of lateral shoot leaves to grape composition might have increased in cases where the main shoot leaf area was lowered at a later stage (e.g. 2 weeks after véraison). The bunches were visually evaluated and divided into classes from dark (class one) to light (class nine). This visual bunch evaluation showed that the mean bunch colour was in class three (lighter than class two) due to the defoliation time. The lateral shoot removal x leaf removal interaction resulted in a mean bunch colour that was in classes 2 and 3. However, within these classes, there was a tendency that bunch colour decreased for defoliation times later than pea berry size. The lateral shoot removal x leaf removal interactions showed that bunch colour was darker when the treatment combinations involved 0% leaf removal. The percentage of bunches with the desired colour was increased by application of the treatments at véraison, compared to the other defoliation times, and also with 50% lateral shoot removal and 100% lateral shoot removal compared to 0% lateral shoot removal. Biochemical analyses confirmed that increased levels of lateral shoot removal generally lowered the anthocyanin concentration regardless of defoliation time. A similar effect on TSS was observed, i.e. from véraison onwards, the application of 50% lateral shoot removal and 100% lateral shoot removal tended to lower TSS. The effect of these levels of lateral shoot removal at véraison was significant. The role of the lateral shoots in colour development and sugar accumulation is therefore emphasized. Furthermore, the special role that lateral shoots also play in berry development is illustrated in that berry mass tended to decrease when 100% lateral shoot removal in combination with 33% leaf removal and 100% lateral shoot removal in combination with 0% leaf removal were applied at véraison. This, together with the positive relationship obtained between grape colour and the lateral shoot leaf area:fruit mass ratio, accentuates the role of active leaf area during the ripening period. The possible effect of the microclimatic light environment on colour must also be considered. However, although the light intensity increased with increased levels of LS, the colour that was obtained was probably not associated with the differences in light intensity. It was found that it is possible to manipulate the colour of Redglobe grapes with defoliation treatments. However, the treatments that have a decreasing effect on grape colour also affected other quality parameters like TSS and berry size negatively. Although, it is possible to reduce the colour of Redglobe through the application of leaf and lateral shoot removal at different defoliation times, the question arises whether the treatment combinations used in this study are worthwhile to pursue because the mean bunch colour that was obtained was still too dark. However, it was possible to increase the percentage of bunches with the desired colour. Therefore, if such treatments are applied, it must be approached cautiously, keeping in mind that assimilate supply has to be sustained throughout the ripening period.

Повний текст джерелаPrimed information is more accessible in memory and can thus easily be recognized. Prerequisites for priming include subliminal perception, goals, reliability, non alert and non habitually. The study aims to gain broader understanding regarding subliminal primings influence. The purpose of this thesis was to see whether the customers in a store could be manipulated, primed, to take a specific colour on plastic bags at checkout and if there are any gender differences in the effect of priming. Participants were 490 customers, of whom 333 men. Two different signs with different colours were placed at the checkout. It was noted if customers chose the primed colour of the plastic bag or not. The results showed a significant difference, the participants chose the same colour on the plastic bag as the sign. No gender differences were found. Research shows that priming effects can be opposed if people make themselves aware of potential unconscious influences.

Повний текст джерелаA spectrally based normalization methodology (Wpt normalization) for linearly transforming cone excitations or sensor values (sensor excitations) to a representation that preserves the perceptive concepts of lightness, chroma and hue is proposed resulting in a color space with the axes labeled W, p, t. Wpt (pronounced “Waypoint") has been demonstrated to be an effective material color equivalency space that provides the basis for defining Material Adjustment Transforms that predict the changes in sensor excitations of material spectral reflectance colors due to variations in observer or illuminant. This is contrasted with Chromatic Adaptation Transforms that predict color appearance as defined by corresponding color experiments. Material color equivalency as provided by Wpt and Wpt normalization forms the underlying foundation of this doctoral research. A perceptually uniform material color equivalency space (“Waypoint Lab" or WLab) was developed that represents a non-linear transformation of Wpt coordinates, and Euclidean WLab distances were found to not be statistically different from ΔE* 94 and ΔE00 color differences. Sets of Wpt coordinates for variations in reflectance, illumination, or observers were used to form the basis of defining Wpt shift manifolds. WLab distances of corresponding points within or between these manifolds were utilized to define metrics for color inconstancy, metamerism, observer rendering, illuminant rendering, and differences in observing conditions. Spectral estimation and manipulation strategies are presented that preserve various aspects of “Wpt shift potential" as represented by changes in Wpt shift manifolds. Two methods were explored for estimating Wpt normalization matrices based upon direct utilization of sensor excitations, and the use of a Wpt based Material Adjustment Transform to convert Cone Fundamentals to ”XYZ-like" Color Matching Functions was investigated and contrasted with other methods such as direct regression and prediction of a common color matching primaries. Finally, linear relationships between Wpt and spectral reflectances were utilized to develop approaches for spectral estimation and spectral manipulation within a general spectral reflectance manipulation framework – thus providing the ability to define and achieve “spectrally preferred" color rendering objectives. The presented methods of spectral estimation, spectral manipulation, and material adjustment where utilized to: define spectral reflectances for Munsell colors that minimize Wpt shift potential; manipulate spectral reflectances of actual printed characterization data sets to achieve colorimetry of reference printing conditions; and lastly to demonstrate the spectral estimation and manipulation of spectral reflectances using images and spectrally based profiles within an iccMAX color management workflow.

Optical and photonic fibers represent versatile systems for light manipulation. They are used to guide, reflect, emit, and absorb light, and can be designed to alter the light's spectral composition in any of these light-matter interactions. Additional functionality arises from the combination of these effects in single fibers, and the ability to employ fibers as individual strands, or as woven networks. Two distinct light-manipulating-fiber systems are the focus of this thesis: (1) photonic fibers, which have vivid structural color that changes reversibly in response to mechanical or electrical stimuli, and (2) leaky light guides, which emit light along their length when illuminated from one end. Mechanochromic fibers that convert a mechanical perturbation into an optical response can be used, standalone or integrated into textiles, as easy-to-read strain sensors. Such fibers respond to elongation with a gradual shift in their reflected color through the visible range of light.
In particular, their use in compressive bandages - discussed in detail in this thesis - could greatly improve the efficiency of compression therapy for chronic venous ulcers and other vascular maladies. Electrochromic fibers exploit the electrochemically-tunable absorption of poly(3,4-ethylenedioxythiphene) polystyrene sulfonate, a common conducting polymer, to design devices that can be flipped between a vivid, structurally colored state, and a dull, absorption-colored state. Custom optical multilayer and lumped parameter models are used to analyze the behavior of these fibers. Leaky light guides, by distributing light throughout volumes of algae culture, could yield greater productivity in microalgae cultivation, while lowering energy requirements. The combination of these factors could enable the economically favorable generation of algal biomass for fuels, feedstock, pharmaceuticals, and many other uses.
A passive system for distributing light throughout culture volumes, by selectively scattering light out of light-guiding fibers, is developed and implemented. The process of designing and manufacturing these leaky light guides, and their use in a variety of laboratory-scale bioreactors with live microalgae cultures, are described.

Повний текст джерелаIdag ökar efterfrågan på smarta robotar som kan ta egna beslut och samarbeta med människor i föränderliga miljöer. Tillämpningsområdena för robotar med kamerasensorer kommer sannolikt att öka i en framtid av artificiell intelligens med algoritmer som blir mer intelligenta och anpassningsbara än tidigare. Syftet med detta kandidatexamensarbete är att utveckla en robotarm som, med hjälp av en kamerasensor, kan ta upp och sortera godtyckliga objekt när de uppträder på oförutsägbara positioner. Robotarmen har tre frihetsgrader och hela konstruktionen är 3D-printad och modulariserad för att vara underhållsvänlig, men också anpassningsbar för nya tillämpningsområden. Kamerasensorn ¨ar integrerad i ett externt kamerastativ med sitt synfält över robotarmens arbetsyta. Kamerasensorn detekterar objekt med hjälp av en färgfiltreringsalgoritm och returnerar sedan storlek, position och signatur för objekten med hjälp av en kantdetekteringsalgoritm. Objektens storlek används för att kalibrera kameran och kompensera för den radiella förvrängningen hos linsen. Objektens relativa position används sedan till invers kinematik för att räkna ut hur mycket varje stegmotor ska rotera för att erhålla den önskade vinkeln på varje axel som gör att gripdonet kan nå det detekterade objektet. Robotarmen har även tre olika potentiometrar integrerade i varje axel för att reglera rotationen av varje stegmotor. Resultaten i denna rapport visar att robotarmen kan detektera och plocka upp till 90% av objekten när kamerakalibrering används i algoritmen. Slutsatsen från rapporten är att förvrängningen från kameralinsen har störst påverkan på robotarmens precision och därmed resultatet. Det går även att konstatera att metoden som används för att korrigera kameraförvrängningen påverkas av geometrin samt orienteringen av objekten som ska detekteras, men framför allt variationer i belysning och skuggor över arbetsytan. En annan slutsats är att belysningen över arbetsytan är helt avgörande för om kamerasensorn ska kunna särskilja objekt med olika färgmättad och nyans.

Повний текст джерелаOil, gas and minerals are indispensable resources for our economies and are sought-after. They are particularly prone to illicit financial flows such as corruption, tax avoidance and money laundering. Awareness of the extent of illicit practices in the extractive sector is relatively new. Over the last two decades, various measures have been adopted, forming an ambitious legal framework to combat illicit financial flows in the extractive sector. Despite the existence of this legal framework, illicit practices are still persistent. Stakeholders within the extractive sector such as companies and public officials have been able to adapt and be creative in order to abuse, circumvent and manipulate this legal framework in order to preserve their advantages and perpetuate illicit financial flows. They can also use legal and financial engineering, which provides them with an arsenal of legal tools and mobilizes experts who master the legal, political and financial environment in which companies and public officials evolve. Hence while wanting to combat illicit financial flows, law can find itself propitious to these illicit practices and even to their service

Using nanostructures to manipulate surface plasmon polariton (SPP) plane waves is an important issue. The interactions of surface nanostructure on SPP wave involve not only the in-plane behavior, but also out-of-plane scattering which is captured as the far-field radiated light. In this dissertation, by using the monochrome laser and multiwavlength laser, the three-dimensional focusing and diverging of SPP waves by a plasmonic structure composed of laser-fabricated gold nanobumps were studied. The forward and backward scattering from individual gold nanobump are observed above and below gold surface, respectively. The gold nanobump structure confers additional three-dimensional propagating wave vectors on SPP wave for departing from surface. A practical application to manipulate the three-dimensional plasmonic scattering is proposed by arranging the gold nanobumps. We manipulate the scattering of SPP waves by various plasmonic structures composed of arranged nanobumps on a gold thin film. Upon controlling the geometry of the plasmonic structures, the height, position, and pattern of scattered light can be modified as desired. It provides a simple and efficient way to project a specific light pattern into free space, and demonstrate the capability of three-dimensional light manipulation. By precisely designing a particular curved structure with appropriate radius of curvature and adjacent interspacing of nanobumps, we can construct a clear single focusing spot at a specific altitude. These results confirm the easy controllability of the focused spot in three-dimensional space by settling the unit curved structures. This research has potential to be applied in the area such as the integrated photonic circuit in the future.

The nano-scale thickness and higher quantum yield compared to other two dimensional materials made transition metal dichalcogenides (TMDCs) a good candidate for realizing ultra-small light emitting devices. However, TMDCs encountered obstacles for practical application since the quantum yields of TMDCs were still relatively low in contrast to traditional semiconductors. Thus, we integrated quantum dots (QDs) with monolayer tungsten diselenide (WSe2), and utilized silver nanodisk (Ag ND) arrays, a kind of plasmonic metasurfaces which could boost absorption and emission at specific resonance frequency, to directly enhance the emission of monolayer WSe2 as well as convert the light from QDs to WSe2. Among the two effects induced by the metasurface, the light conversion or so-called color conversion described the process of one material absorbing the light from other material or source, and then re-emitted the light with absorber’s wavelength, which was a crucial phenomenon used in illumination or display. There were three parts of experiments in the thesis. The first part of experiment will focus on how to realize the Ag ND metasurfaces with desired resonant wavelengths. With the help of FEM simulation as well as bilayer photoresist lift-off process, we designed and fabricated a series of metasurfaces for studying their impact on the color conversion. In the second part, we observed the dependence of plasmonic resonant wavelength. The metasurfaces were made on silica with monolayer WSe2, and their direct enhancement to TMDCs was measured by photoluminescence (PL) system first. Then, we spray coated QDs on them for studying color conversion and found the ideal resonant wavelength located at position between QDs and WSe2 but closer to QDs. At last, we attempted to further increase the conversion efficiency by tuning the metal density of our Ag ND metasurfaces while making all their resonant wavelengths around the ideal position observed in second part. We repeated the measurement in second part and found the density of Ag ND could also affect the enhancement along with conversion efficiency. With higher density came stronger localized surface plasmon effect, which result in the improvement of both effects we got. The successful demonstration of controlling light conversion between QDs and WSe2 through plasmonic metasurfaces suggested that the TMDCs had the potential to be applied to light emitting devices or display technology such as white light emitting diodes (WLEDs) with the assist of localized surface plasmon effect.

The little size of the smartphone screen limited the amount of information that can be presented in a single scene, thus the user needs to give more instructions to system for getting corresponding amount of information in the traditional screen, therefore, if the manipulation performance of smartphone can be improved through the design, it can save a lot of unrevealed time of the user. Due to the human performance is primary affected by the ability of the human information process, and the vision is the primary channel for human to receive the exterior information. In the visual performance aspect, the former research indicated that the color is important to influence the human visual performance, and the ability of human information process can be affected through the presentation of information that is changed by colors, thus improving the visual performance. Therefore, the research discussed whether the effect on the visual performance through applying the color can be applied to improve the manipulation performance in the smartphone interface. The research used experimentation as the research method, applying the color combination of font color and background color to change the presentation of number information on screen, and requesting the participant to execute the visual searching and the touch manipulation on the right number. The experiment applied the 7 different hues and the 3 different luminance contrast to construct the color combination as the independent variable, and applied the manipulation time of the participant as the dependent variable, and analyzed the result of experiment through One-way ANOVA statistic analysis. The result of the experiment: in the same luminance contrast combination, the 7 different hues have no significant influence on the manipulation time, indicated that the color combination of experiment have no significant influence on the manipulation performance among the hues; in the same hue, the 3 different luminance contrast combinations have no significant influence on the manipulation time, indicated that the color combination of experiment have no significant influence on the manipulation performance among the luminance contrast combinations. Due to the result of experiment is not consistent with the expectation of the research hypothesis, therefore, discussing the factors that can influence performance such as the variety of color combinations of font color and background color, the size of font, the number of groups, the spacing between information groups, the density of information in the screen, the movement distance of touch manipulation, the balance of the learning effect of the participant, and the test patterns that is applied to balance the movement distance and the learning effect in the experiment, whether the relation of the patterns and the tests is fair enough in design. As a result of the discussing of the factors, the factors that are related to the visual performance and the reaction time applied the suggestion of the former human factor engineering research except the color combination limitation, therefore, the color combination of the research can not induce significant variation among the tests is because of the variety limitation of the color-pairings, or, in the condition that other factors that has been proved do influence performance were adopted in optimization, the color combination of experiment can not affect the manipulation performance in smartphone interface. On the other hand, there is a probability that one of the experiment control variables is the dominant factor that can influence the manipulation performance.

Повний текст джерелаThe aim of this placebo-controlled clinical trial was to determine the role of spinal manipulation in the management of irritable bowel syndrome (IBS), in terms of the patients' subjective response to treatment. It was hypothesized that spinal manipulation would have a greater effect than placebo in reducing the intensity of the symptoms of IBS. Thirty subjects diagnosed with IBS were randomly divided into two groups. Each group consisted of 15 subjects, aged between 18 and 50. Patients were treated twice a week for three weeks and once in the fourth week. Thereafter, each patient returned approximately 1 month later to be assessed for any longer-term benefit to treatment. Patients in the experimental group received spinal manipulation directed at areas of spinal fixation, as determined by motion palpation. Patients in the control group were treated using a detuned ultrasound machine over areas of spinal fixation. Treatment was performed with the same degree of enthusiasm in both groups, where possible.

The colorchip (PANTONE® formula gude solid uncoated), digital image acquisition and processing (DIAP), and high performance liquid chromatography analysis were used in the present study. In experiment I, 4.09±0.02 g blood parrot were fed with eleven commercial enhanced pigment feeds coming from domestic and foreign countries for two weeks. A control diet without pigment included was made in this study. The questionnaires of the behavior of the ornamental fish consumers were investigated. There were no significant different weigh gain of fish fed control and commercial diets. The astaxanthin concentration of commercial diets ranged from 5.7 to 1164.2 mg/kg. After one week feeding, the astaxanthin concentrations of fish fin of D grouper, the fish skin of C group and the fish muscle of I group showed the highest levels, 26.96 + 1.75, 22.28 + 0.14 and 18.55 + 0.14 mg/kg, respectively. However, after two weeks feeding, the astaxanthin concentrations of fish fin of B group, and the fish skin and fish muscle of E group showed the highest levels, 26.97 + 1.75, 20.74 + 0.37, and 7.6 + 0.17 mg/kg, respectively. Through DIAP observation, the highest level of L*, a*, b*, C* and H* values were found in H group (55), J group (22), D group (30), E group (35) and control group (1.4), respectively. Through color chip observation, the highest level was found in D group (43) and the lowest level was found in K group (16). The questionnaire was distributed to the ornamental fish trade show during October. From this survey, we know the following facts: 1) Taiwanese consumers like to raise small size ornamental fish; 2) they like the colorful ornamental fish; 3) they can afford below 250 NT dollars for 100 g diet; 4) they are used to buy the domestic diets rather than alien diets. In experiment II, 6.41±0.10 g blood parrot were fed diets containing 0, 50 (AX50), 100 (AX100), 150 (AX150), 200 (AX200) and 250 (AX250) mg/kg astaxanthin for three weeks. Fish were fed twice a day (9:00, 17:00) of 2% body weight. After two weeks feeding trial, fish fed AX200 diet had the highest concentration of astaxanthin in fin and skin (18.84±1.73 and 14.08±0.90 mg/kg, respectively). The a* and H* values were optimum in fish fed AX150 diet. In experiment III, 2.87±0.02g gold fish were fed diets containing 0, 25, 50, 75 and 100 mg/kg astaxanthin for four week. Fish were fed 1% body weight diets twice a day (09:00 and 17:00), and photoperiod was maintained 10L:14D in light treatment (AX0-L, AX25-L, AX50-L, AX75-L and AX100-L diets) and 24D in dark treatment (AX0-D, AX25-D, AX50-D, AX75-D and AX100-D diets). Fish fed AX50-L diet showed the highest concentration of astaxanthin in skin and muscle (18.50±2.92 and 27.52±0.57 mg/kg, respectively) after four weeks feeding trial. However, fish fed AX100-L diets showed the highest level of a* and H* values. In dark treatment, the highest concentrations of astaxanthin were found in skin and muscle when fish fed AX50-D and AX25-D diets repectively (19.69±1.17 and 18.78±1.07 mg/kg, repectively), and The a* and H* values were highest in fish fed AX100-D diet.

In this thesis, we systematically study the GaN-based LEDs in two aspects: the emission characteristics of semipolar InGaN/GaN quantum well with strain manipulation and the carrier transport of dual color light-emitting-diodes. The first part of the thesis investigates the optical anisotropic behaviour of the (11$ ar{2}$2) and (20$ ar{2}$1) semipolar InGaN/GaN single quantum well LEDs. The influence of different indium compositions of the quantum well, and different degrees of strain relaxation along the projection of $c$-axis are discussed in detail. Our developed one dimensional model is used to solve drift-diffusion, Poisson equations, and 6$ imes$6 $kcdot p$ Schr"{o}dinger equations to investigate the band structures and emission characteristics. The study shows that for the (11$ ar{2}$2)-plane, there exists a switching of light emission polarization directions with the increase of indium composition. While for the (20$ ar{2}$1)-plane, the polarization ratio $ ho_{y''x''}$ can be achieved over 90$\%$ with a high indium composition and a large degree of strain relaxation, which is promising for laser diodes and LCD backlight modules applications. The second part of the thesis will investigate the carrier transport of a novel GaN-based dual color light-emitting diodes (LEDs) with an additional p-GaN layer inserted between the two-color wavelength MQWs. We apply our 2D Poisson, drift-diffusion solver with an extra plug-in function considering the indium fluctuation to make the simulation result more precise. The result shows that by properly selecting the doping density and the thickness of the p-GaN insertion layer, we can effectively optimize the ratio of output light intensities between the dual color wavelength even under a low bias current density.
