CHAPTER – 1 1. INTRODUCTION Carbon nanotubes are allotropes of carbon with cylindrical nanostructure. Constructed with length-to - diameter ratio of up to 132,000,000 :1. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. Nanotubes are members of fullerene structural family. Nanotube’s walls are formed by one-atom thick sheet of carbon called Graphene. The combination of…

• Samples taken from the trees were shade dried for ten days before carrying out the experiments. • After drying of leaves, they were pulverized. • From the pulverized samples, 10 gm of material was weighed and soaked in 100 ml of each Acetone, methanol and water for at least 24 hours(aqueous) and to a maximum of 72 hours(methanolic and acetone). Fig : Extracts and Essential Oil of Cinnamomum tamala…

International investment law as an instrument for sustainable development The relation between international investment law and sustainable development is ?two sided?.[footnoteRef:2] This statement is also supported by Newcombe, he states sustainable development is indeed needed in the future, thus, foreign direct investment (FDI) could be the main instrument to ensure any development agenda.[footnoteRef:3] Furthermore, Foreign direct investment also contributes toward financing sustained…

Extra Virgin Olive Oil Impairs UV-Induced Cell Damage in Cancer-Prone Mice INTRODUCTION Ultraviolet radiation produces various wavelengths that are part of the electromagnetic spectrum. The four different UV wavelengths are classified as UVA, UVB, and UVC. UVA produces the longest wavelength at 320-400nm, UVB produces wavelengths from 290-320nm, and UVC wavelengths are the shortest wavelength that is completely absorbed by the ozone layer. However, it is known that…

There is a study that done by Harvard students in which they observed pregnant women who were exposed to high levels of pollution. The effect that the children that were born were exposed to getting autism. Autism is an disorder that can affect brain development, cause abnormals behavior in a social environment, and cause speech impairments. Pollution also causes a lot of problems within the body such as heart disease, lung cancer, and asthma. Raising awareness for both of these problems can be…

INTRODUCTION Oral Controlled Release Drug Delivery Systems1, 2: Oral controlled release drug delivery is a drug delivery system that provides*give the continuous oral delivery of drugs at predictable and reproducible kinetics for a predetermined period throughout the course of GI transit and also the system that target the delivery of a drug to a specific region within the GI tract for either local or systemic action. All the pharmaceutical products formulated for systemic delivery via*throw…
