acetylcholinesterase and 5’-nucleotidase were approximately 4-， 2.5- and 3-times， respectively， higher in the plasma membrane fraction compared to those in crude homogenates. The eleιtron microscopic exa mination of the prepared SPMV showed verγ high purity. The vesic1es， which were separated according to size， demonstated a homogeneous distribution and no longer showed the presenc... In order to provide a basis for studying the molecular mechanism of pharmacological action of local anesthetics and to develop a fluorescence spectroscopic method which can detect the microviscosity of native and model membranes using intramolecular excimerization of 1,3-di(l-pyrenyl)propane (Py-3-Py), we examined the effect of lidocaine·HCl on the microviscosity of model membranes of phosphatidylcholine fraction extracted from synaptosomal plasma membrane vesicles (SPMVPC). The excimer to... -

total of 50 conidia per fruit. Near real-time microscopic images were acquired and displayed onto a video monitor using a charge-coupled device camera (KP-C550; Hitachi, Tokyo, Japan) attached to the light microscope. Images of germ tubes on the video monitor were transcribed onto transparency films with a marker pen, and the transcripts were traced with a graphics digitizer (SummaSketch II;... 42 μm long. Prolonged rewetting up to 40 hr did not restore germ tube elongation on slide glasses under substrate treatments. Model simulation using weather data sets revealed that ending infection periods by a dry period of at least 1 hr decreased the daily infection periods, avoiding the overestimation of infection warning. This information can be incorpo- rated into infection models for scheduling fungicide sprays to control apple white rot with fewer fungicide applications. -

off by a razor blade. Appressorium formation from germinating conidia on the fruit surface was observed under light microscope at 400X magnification without staining. One hundred conidia from 5~6 microscopic fields of views were examined for appre- ssorium formation and the percentage of conidia forming appressoria was determined. If the original conidia from which appressoria were formed could... A logistic model for describing combined effects of both temperature and wetness period on appressorium formation was developed using laboratory data on percent appressorium formation of Colletotrichum acutatum. In addition, the possible use of the logistic model for forecasting infection risks was also evaluated as compared with a first-order linear model. A simplified equilibrium model for enzymatic reactions was applied to obtain a temperature function for asymptote parameter (A) of logistic... -

files. If the motion trace is obtained for bus, it cannot be used for other vehicles. Moreover, only few numbers of traces are available. Traffic based simulators [16] are useful in evaluating microscopic traffic. Micro simulation creates a virtual model of urban transportation infrastructure to simulate the interaction of traffic. It captures the influence of real world traffic using series of... based model has been proposed to define the mobility behavior of the vehicles. Different types of influence on the mobility have been lumped and the profile of the motion of vehicles has been modeled as a Gaussian profile. In this model, a driver, first, selects the source, destination and his path and then, selects the parameters of the profile according to his/her presumption. Simulation and results show that profile based model is able to generate realistic and smooth mobility patterns. -

of deposits to clarify the specific reasons that affect the degree of ash deposition. The SEM images and EDX results of deposits collected at 80 0℃ are shown as Fig. 4 to Fig. 6. Obviously, the microscopic morphology of the ash deposits of the three fuels at the high and bottom layer is different. As far as the shape and particle size of Berau coal is concerned, the shape at the top layer... In recent years, many countries have invested enormous efforts to tackle increasingly harsh environmental problems, especially the greenhouse effect. The addition of biomass into coal is regarded as a promising technology to mitigate CO2 emissions. However, the costs related to retrofitting injection systems and unstable combustion inhibit this option. Therefore, this thesis developed a two-in-one fuel that impregnates molasses into the holes of low-rank coal(LRC), which can be directly applied... -

al., 2013b). The microscopic observations and histological section images of the TM, middle ear cavity, and ossicles showed the morphological or middle ear structural changes in AOM ears. Figure 2 displays the microscopic observations of the TM and middle ear in control,OME, and AOM ears of guinea pigs (Guan et al., 2013a). In normal ear (Figure 2A), the TM was translucent and no fluid was visible... Hearing impairment is one of the most common physical disabilities in the world. Conductive hearing loss results from dysfunction of the middle ear, and sensorineural hearing loss results from abnormalities within the cochlea or central nervous system. To improve the diagnosis of hearing loss and develop new technologies for restoration of hearing, changes of the middle ear and cochlear functions in relation to ear structural disorders in hearing impaired ears need to be characterized. This... -

of volume resistivity. 2.4. Microscopic measurements The dispersion and distribution of CNT in the PC matrix were measured by transmission electron microscopy (TEM, JEM- Fig. 2. Schematic diagram of melt extruding with various loads. PC: polycarbonate, CNT: carbon nanotube. Table. 1. Extrusion conditions for preparation of MWCNT/PC nano- composites in this study Condition Screw speed (r/min)... Multi-walled carbon nanotube (MWCNT)/polycarbonate (PC) nanocomposite was prepared by direct melt mixing to investigate the effect of the shear rate on the surface resistivity of the nanocomposites. In this study, an experiment was carried out to observe the shear induced orientation of the MWCNT in the polymer matrix using a very simple melt flow indexer with various loads. The compression-molded, should be eliminated. MWCNT/PC nanocomposite sample exhibited lower percolation thresholds (at 0.8... -

limited to low surface energy materials, and it can be extended to the fabrication of hydrophobic surfaces for many systems. Various low surface energy materials have been developed to modify microscopic scale surfaces to form superhydrophobic surfaces. Fluorinated compounds, silane, and long alkyl chain fatty acids are typical low surface energy com- pounds, and have the ability to endow... Materials with appropriate surface roughness and low surface energy can form superhydrophobic surfaces, displaying water contact angles greater than 150°. Superhydrophobic carbon-based materials are particularly interesting due to their exceptional physicochemical properties. This review discusses the various techniques used to produce superhydrophobic carbon-based materials such as carbon fibers, carbon nanotubes, graphene, amorphous carbons, etc. Recent advances in emerging fields such as... -

도로용량편람에서 제시하는 서비스수준은 새로운 교통시설 설치 또는 기존 시설 확장에 근거로 사용되고 있다. 신호교차로 서비스수준 분석은 다섯 단계로 진행되는데 그 중 3단계는 차로군 분류 단계이다. 이 단계에서 분류된 차로군으로 연속적인 분석을 진행하기 때문에 서비스수준 분석 시 중요한 요소 중 하나이다. 하지만 본 연구에서 분석한 결과 회전교통량이 적은 경우에도 불구하고 실질적 전용회전차로군으로 분류되는 점을 발견하였다. 이러한 문제점에 대한 대안으로 USHCM의 차로군 분류 방법을 차용하는 방법, 공용차로 당...
