Analysis of Film Waving in LCD Backlight Module

Su, Pei-chun 03 September 2005 (has links)
Liquid crystal display is the most valuable and universal produce of the electric monitor presently. Due to the non-luminant display device, it must use the light source of the backlight module to reach display effect . In backlight module field , it is focus on the even distribution of the light source and the perfect appearance without any defect occurrence. Besides, the existence of film waving will cause the bad phenomenon .To improve and avoid the defect occurrence,through the workable analysis experiment can find the real element progressively . In the experiment , we will focus on the characteristic of the film material and each material¡¦s dimension which analyze by BM-7 and Nieo LCD analyzer,etc. According to angle orientation.From the result,we can realize that the stronger structure material and larger heat capacity of Diffusion Film, will decrease the expand and shrink for temperature , and film waving caused by temperature changing, which may resolve the film waving effectively.

The application of phage display technique in oral cancer treatment

Wang, Chun-fu 23 June 2007 (has links)
Phage display is a molecular technique accomplished by incorporation of the nucleotide sequence encoding the protein to be displayed into a phage or phagemid genome as a fusion to a gene encoding a phage coat protein. After several rounds of selection and amplification, high affinity phage clones, and thus high affinity ¡§homing peptides¡¨ can be obtained. Cell-binding homing peptides selected in this manner could be linked by physical or genetic manipulation to gene therapy vectors that mediate their own entry (viral or non-viral vectors) to facilitate targeting. Homing peptides that target specific cellular receptors can also be used as a treatment modality to induce various signal transduction pathways or even apoptotic signals of cancer cells. Oral squamous cell carcinoma (OSCC) is one of the most common cancers in the world. It has become the fourth cancer death reason of males in Taiwan. Radical surgery combined with postoperative chemotherapy and/or radiotherapy is still the major modality for treatment of OSCC. The 5-year survival rate of OSCC is still discouraged in recent years. Patients with OSCC present numerous challenges to treating physicians. In this study, we aimed to isolate and identify homing phage clones specific to oral cancer cells by panning with a random phage peptide library. The homing phage clones will be used as a basis to improve targeting specificity of gene therapy vectors. A NCBI BLAST search was performed and close similarities were found to several important molecules biologically with the homing peptides carried by phage clones. Characterization of the selected phage-29 was then studied by immunohistochemical methods. Internalization of this phage-29 is sequence-specific and mediated by integrin £\v£]6 in HSC-3 cells rapidly. We also confirmed that the integrin £\v£]6-targeting homing peptide is universally useful in all major kinds of head and neck cancer. We will further study the possible biological functions of the other homing peptides to see whether these peptides could have potential applications for oral cancer treatment.

The Research of Using Scenario Analysis and STP Strategy to Research New Products Entering The Market-Take CNT-FED for Example

Chuang, Fu-Chi 02 July 2003 (has links)
The tendency of using flat panel display (FPD) to be the final receiver of digital information is going to take shape because of the digitization. Besides the traditional cathode ray tube (CRT) display , there are several display products in the FPD market, such as liquid crystal display (LCD) , Plasma Display Panels (PDP), organic light-emitter diode (OLED) and so on. Nowadays, because of the innovation of nanotechnnology, which drove the development of carbon nanotubes field effective display (CNT-FED). This new products driven by technology will confront two questions as follows : (1) The can¡¦t understand the real scale of market. (2) They can¡¦t forecast the time they need to spend to realize the market chance. Therefore , how to modify the new-products-entering model is an worthy problem to research . The research was done by using the ways of interviewing experts and secondary data collection. Then, we used scenario analysis to build the most possible scenario that CNT-FED may encounter in the future. Under the scenario, we used the approachs of STP strategy to develop th model that CNT-FED enters the market in the future.From the conclusion of this research, we know that CNT-FED should choose the market segment of big panel at the first time entering the market, and it will complete with PDP. Because the performance of CNT-FED is much better than PDP , we need to let the customers realizing and identifying this difference. Therefore, we can reduce the weakness of CNT-FED because of its high price , and , then, we can build the niche market of CNT-FED.

3D engine for immersive virtual environments

Anderson, Christopher Dean 17 February 2005 (has links)
The purpose of this project is to develop a software framework, a 3D engine, which will generate images to be projected onto facets of a spatially immersive display (SID). The goal is to develop a software library to support the creation of images of specified 3D environments which are specific to the display geometries of a polyhedral class of SIDs. Part of this goal is developing auxiliary software to allow this library to be thoroughly tested. When properly working, the images being displayed on adjoining faces of the SID appear spatially and temporally consistent with one another, creating the illusion that the user is within a surrounding three-dimensional space.

Exploring the jumping spider mimicry of Eugauria albidentata (Lepidoptera, Crambidae, Musotiminae) through ethological and visual ecological approaches

Wang, Mu-Yun 12 August 2009 (has links)
Predator mimicry refers to a peculiar and rarely investigated example of Batesian mimicry in nature. This mimicry scenario exists between predator and prey in which prey resembles the form, behaviour or signals exhibited by the predator to avoid or reduce risk of predation. In the Lepidoptera, there are many micromoth taxa that are phylogenetically unrelated and geographically widespread exhibiting colour patterns that are putatively involved in jumping spider mimicry. In the present study, we aimed to answer the following questions: (1) what kinds of colour pattern and display behaviour could really allow the moths to participate in jumping spider mimicry? (2) does the moth receive different predation pressure from male and female spiders? (3) why is the mimetic moth not immediately taken by the spider? Is it really because the spider sees the moth as another spider? (4) Is there any evidence justifying any visual signal displayed by the moth participated in the jumping spider mimicry? The experimental results showed that the predation rates on mimetic moths of jumping spider were significantly lower than the non-mimetic moths, and spiders exhibited specific behaviour that was displayed for conspecific communication. But not all the presuming mimicking moths can decrease predation from the spiders. Female spiders show significantly higher predation rate to the mimicking moths, while male spiders tend to display more frequently to the moth. In behaviour comparison test in male jumping spiders, we found the behaviour displayed toward mimicking moths are closer to conspecific or heterospecific female spiders, suggesting that female spiders are more likely to be the model of the mimicry systems. Previous studies have shown that UV and fluorescent signals are important in courting behaviour of jumping spider, so we block the UV reflectance signals on the wing pattern of the mimetic moths. The results show that the predation rate of moths without the UV signals is significantly higher than control group which blocked the non-ultraviolet patterns. However, there were still several jumping spiders displayed to the UV-blocking moth, suggesting the UV signals are not the only feature participate in the jumping spider mimicry system.

Identification of novel allosteric modulators of the glycine receptor using phage display technology

Tipps, Megan Elizabeth 31 October 2011 (has links)
The glycine receptor (GlyR) is a ligand-gated ion channel and a member of the cys-loop receptor family. Like other members of this family, the GlyR is a target for many drugs of abuse, including alcohol. While the effects of alcohol on these receptors have been well-characterized, the contribution of each receptor subtype to the overall physiological and behavioral effects of alcohol use are unclear. This is partially due to the limited pharmacology of the GlyR, which limits the ability to isolate GlyR function within a complex system. One method for identifying compounds that bind to and modulate a given target is phage display. This approach uses bacteriophage to screen a large number of peptide sequences for affinity at a given target. We developed a phage selection protocol to identify peptides that bind to the GlyR. These peptides were then tested for functional effects at the GlyR using two-electrode voltage clamp physiology. We identified several peptides that were able to modulate GlyR function. Peptide D12-116 showed specificity for the GlyR over two closely related γ-aminobutyric acid (GABA) channels. In addition, this method is easily adapted for the selection of peptides that bind to any cell-expressed target, increasing the utility of phage display in the neurobiology field. Another shortcoming in GlyR pharmacology is the lack of modulators with specificity for a single GlyR subtype. We next adjusted our selection protocol to search for peptides that can distinguish between the different Gly R α subtypes. We identified several promising lead peptides that show subtype preference. Finally, we found that trifluoroacetic acid (TFA), a common peptide contaminant, also modulates GlyR function. This finding has important implications for both previously reported peptide modulators and the pharmacology of several volatile anesthetics, for which TFA is the major metabolite / text
