Structural Analysis of Hirudin Using FT-IR and FT-Raman Spectroscopic Techniques
FT-IR and FT-Raman spectra of hirudin have been recorded from the native solid hirudin. The conformation of the molecule has been discussed on the basis of IR and Raman data. It has been concluded that hirudin molecule has a mixed a-helix and random coil conformation.
متن کاملATR FT-IR Imaging of Human Hair Cross-Section
Human hair is typically 50-100 μ in diameter, previous transmission and ATR studies of its cross section1,2 reveal three major identifiable regions. The core, or medulla, typically 5-10 μ in diameter, is surrounded by the cortex, making up the bulk of the hair and finally an outer layer or cuticle, typically less than 5 μ in thickness. Biochemical compositional studies may be performed by exami...
متن کاملSpatial Resolution in ATR FT-IR Imaging: Measurement and Interpretation
ATR FT-IR imaging with germanium crystals offers the potential for acquiring infrared spectral images at up to four times higher spatial resolution than is possible using conventional reflectance or transmission imaging. There is often some confusion over the meaning and inter-relationship of terms such as “spatial resolution,” “pixel size” or “sampling interval,” and it may be hard to understa...
متن کاملanalysis of ruin probability for insurance companies using markov chain
در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولSurface characterization of feldspathic ceramic using ATR FT-IR and ellipsometry after various silanization protocols.
OBJECTIVES This study characterized the feldspathic ceramic surfaces after various silanization protocols. METHODS Ceramic bars (2 mm × 4 mm × 10 mm) (N = 18) of feldpathic ceramic (VM7, VITA Zahnfabrik) were manufactured and finished. Before silane application, the specimens were ultrasonically cleaned in distilled water for 10 min. The ceramic specimens were randomly divided into nine group...
