of cataract formation (Cuttriss et al.,2011). Although the other type of carotenoids which are mostly occur in green leaves lacking in pro-vitamin A, they are still important to human health as they may have relation to cancer prevention. 2. Fourier transforms infrared spectroscopy…

At the time of the paper’s publication, the CW NMR was not the conventional norm for NMR spectra measurements. Fourier Transfer (FT) NMR was the alternative NMR machine that was available. FT-NMRs offeed better resolution and all nuclei were excited at the same time instead of measuring the absorption of individual nuclei in a sweeping fashion. However, the CW NMR…

1. INTRODUCTION Electrochemical Impedance Spectroscopy is an effective method of analyzing the intricate electrical resistance of a process and it is sensitive to surface phenomena and changes in the bulk properties. Thus it plays a major role in electrochemical research. It has been diligently used for the interpretation of corrosion mechanisms and in the characterisation of charge transport over the membrane. In the area of biosensors, it is especially appropriate for the detection of…

2. Materials and Methods: The keratin was extracted from Chicken feather which were collected from the local market of Raipur (21.14°N 81.38°E) Chhattisgarh, India. The 91% food grade alginate (sodium salt form) was purchased from Loba Chemie. The β-mercatpoethanol (mol. wt. 78.13) from LOBA Chemie, sodium dodecyl sulfate (SDS) (mol. wt. 288.38) and urea (mol. wt. 60.06) was purchased from Merck, and ethanol was purchased from Sigma-Aldrich. Antimicrobial strain of gram negative bacteria…

A novel solid-phase synthesis methodology of N-substituted-2-aminothiazolo[4,5-b]pyrazine derivatives was developed. The key step in this synthesis strategy is tandem reaction of isothiocyanate terminated resin 2 with o-halo-2-aminopyrazine, affording cyclized 2-aminothiazolo[4,5-b]pyrazine resin 4. To increase the diversity of our library, Suzuki coupling reaction was performed at the position C6. Further functionalization of 2-aminothiazolo[4,5-b]pyrazine core skeleton with various…

“This is by far the worst water quality we’ve ever seen in our sailing careers,” said Ivan Bulaja, a coach for an Austrian team training at Guanabara Bay in Rio de Janeiro, where the 2016 Olympics will be held. The waters are polluted with sewage, dead fish, and trash, posing a serious threat to athletes training or competing there. Kristina Mena, a professor of public health, is an expert in water quality, and conducted a risk test for athletes competing in the waters Rio, assuming they would…

Introduction Throughout the world, millions of tons of plastic are produced annually and used in countless ways, from packaging to exfoliants in cosmetics (REF). Plastic’s wide popularity stems from its desirable properties, such as being aesthetically pleasing and cost effective. Much of the plastic on the market consists of disposable, one-time-use items. Discarded plastic then accumulates in the environment; so far many studies have shown that plastic accumulates in marine ecosystems…

Differences between Human Hairs and Animal Hairs Once determining that the fibrous evidence is a hair, our next step is on how to distinguish the feature differences between a human hair and an animal hair as shown in Table 8 (Sapp, 2004). (33 words) Animal Hair Coronal Spinous Human Hair Imbricate Table 8. Feature Differences between Human…

200°C followed by a cooling to 25°C to erase the thermal history, then a second heating was made to 200°C. Heating and cooling rate was always of 10°C/min under nitrogen flow of 40 ml/min. The functional groups of PLA and LA can be analyzed by Fourier Transform Infrared Spectroscopy…

The most important advantage is that person walking image can be captured from long distance and the image is then processed with low resolutions. Here focus on two different techniques Principle Component Analysis (PCA) only and PCA with radon transform (RT) on machine vision for gait recognition purposes. In gait recognition silhouette defined as a region of pixels of the walking person and the silhouette extraction mainly focuses on segmenting the human body. The silhouette extraction…
