Essays on Spectra

The general effort involves in-depth investigation into the fundamental mechanism of turbine engine noise generation and will heavily depend on the results of current Department of Transportation and National Aeronautics as well as Space Administration engine noise reduction programs (Prasad & Atassi, 2009). The first effort in this series is focused toward afterburning supersonic jet exhaust system that has an operating condition typically of supersonic transport (SST) and long-range strategic aircraft propulsion system. The supersonic jet exhaust noise effort entails three programs directed tow developing the technology to significantly reduce supersonic aircraft population system noise with minimum associated weight penalties ...

Raman spectroscopy is dependent on scattering of light. When light interacts with matter, energy exchange can take place through absorption, simulated emission, Raman scattering or spontaneous emission. In Raman scattering, the emitted photons have less energy and lower frequency in comparison with the absorbed photons. Some energy of the emitted photons is transferred to the molecules. Raman spectroscopy is a method which collects the chemical fingerprints associated with molecules. Every molecule has different levels of vibrational energy and the emitted photons experience shift in their wavelengths. The wavelength shifts are collected,examined and analyzed for sample identification. Raman spectroscopy ...

Introduction:

Nanobiotechnology serves as an imperative technique in the development of clean, nontoxic, and eco-friendly procedures for the synthesis and congregation of metal NPs having the intrinsic ability to reduce metals by specific metabolic pathways. Silver nanoparticles are particularly interesting nanoscale systems due to the ease with which they can be synthesised and modified chemically. Synthesis of silver nanoparticles has been widely researched due to their interesting size and shape-dependent properties [26]. These novel properties can be tailored by controlling their size, shape, composition, structure and crystallinity. Due to their size features and advantages over available anti-microbial properties, chemical imaging ...

Chapter 1 – Introduction to Color Study

1. What is the difference between direct light and reflected light? Give examples of each. Direct light travels from the source to the destination without being interrupted while reflected light is the light produced when the direct light bounces off a material. One example of direct light is the sunlight while reflection from the mirror is an example of reflected light (Young, Freedman & Ford, pp. 1080). 2. Describe the cause of color, the means used to generate it, and the effect. Light consists of a spectrum of light wavelengths which have a representative color; thus, upon reaching the retina ...

I. Introduction Advances in recombinant DNA technology and bioinformatics-based data analysis have driven the explosion of structural biology in the last two decades (Kelly, Jess, and Price 119). This has resulted to the identification of at least 2000 proteins annually and a growing need in performing structural studies in these new proteins. The current trend involves the concern of analyzing protein structures close to its natural conditions (and other conditions) and of measuring their rates of structural changes, an essential factor in their biological functions. The technique of circular dichroism (CD) has gained an increasing popularity in addressing these ...

Summary of Article

INTRODUCTION Altered oligonucleotides, specifically, labeled RNA serve as important tools in biochemical and biomedical research and have been commonly utilized for therapeutic and analytical purposes . Although there are many studies on post-synthetic techniques on DNA, such as by Marx et al., very few reports have described the techniques related to RNA. An efficient automated RNA synthesis with an optimal yield is a prerequisite for post-synthetic derivatization. It is a commonly accepted truth that RNA production is much more troublesome and challenging than DNA synthesis, owing to its lesser coupling efficiency in the synthesis cycle along with the requirement to ...
