The light propagates and is being guided by the core which is surrounded by the cladding. Light travels in the optical fiber in the form of total internal reflection in the core of the fibers. The flexibility, low tensile strength, low signal loss, high bandwidth and other characteristics of optical fibers favors it for use as a delay medium in many applications. Another favorable characteristic of optical fiber delay lines is are their relative insensitivities to environmental effects and electromagnetic interferences. The immunity of optical fibers to interferences and their less weight added advantages to it for use as delay medium. Single-mode and multi-mode are the two most popular types of optical fibers. Single-mode fibers have good propagation and delay properties with a minimal loss that allows the signal to propagate in a large distance with insignificant distortion or attenuation. The percentage of power transmission of single-mode fibers is found to be higher than that of the multi-mode fibers. It is, therefore, a preferred type for use as a delay line. In this paper, relative studies of the two optical fibers modes, and the results of power input/output measurement of the two modes are presented with a view to com i ng up with a better type for use as a delay medium.","PeriodicalId":236431,"journal":{"name":"MatSciRN eJournal","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134581479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite its rapid growth nanotechnology has largely been ignored by the average consumer. As a result, nanotechnology has flourished perpetuating the notion of a technology filled with infinite promise and the possibility to reshape our everyday lives for the better, with the creation of nano-medicines, improved manufacturing techniques, and access to greener energy. But, as with most technology, nanotech similarly comes with a darker side. While it is understood that nanomaterials threaten our ecosystem, the precise mechanisms and impact of these harms are largely unknown as are the potential risks to human health. Moreover, in the absence of a comprehensive regulatory framework, and due to the highly technical and uncertain nature of the science involved, efforts to research the environmental ramifications of nanotechnology can often prove frustrating. For all of these reasons, a primer focusing on the availability of resources in this area seems a timely and appropriate addition to the existing scholarship in the field. As such, this article provides environmental legal researchers and practitioners with a guide to researching the environmental, health, and safety ramifications of nanotechnology. The article discusses effective strategies for researching this topic in the United States and provides an annotated list of key Internet resources, agencies, reports, monographs, and articles.","PeriodicalId":236431,"journal":{"name":"MatSciRN eJournal","volume":"1138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123202774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vadlamani","doi":"10.2139/SSRN.1693838","DOIUrl":"https://doi.org/10.2139/SSRN.1693838","url":null,"abstract":"Current medicine is limited both by its understanding and by its tools. In many ways, it is still more an art than a science. Today’s drug therapies can target some specific molecules, but only some, and only on the basis of type. Doctors today can’t affect molecules in one cell while leaving identical molecules in a neighboring cell untouched because medicine today cannot apply surgical control to the molecular level. To understand what nanotechnology can do for medicine, we need a picture of the body from a molecular perspective. There are opportunities to design nanosized, bioresponsive systems able to diagnose and then deliver drugs, and systems able to promote tissue regeneration and repair (in disease, trauma and aging), circumventing chemotherapy. The long term goal is the development of novel and revolutionary bimolecular machine components that can be assembled and form multi-degree-of freedom nano devices that will apply forces and manipulate objects in the nanoworld, transfer information from the nano to the macro world, and travel in the nano environment. These machines are expected to be highly efficient, controllable, economical in mass production, and fully operational with minimal supervision. The emerging field of medical nanorobotics is aimed at overcoming these shortcomings. Molecular manufacturing can construct a range of medical instruments and devices with greater abilities. Ongoing developments in molecular fabrication, computation, sensors and motors will enable the manufacturing of nanobots. These are theoretical nanoscale biomolecular machine systems within a size range of 0.5 to 3 microns with 1-100 nm parts. Work in this area is still largely theoretical, and no artificial non biological nanobots have yet been built. These ultra miniature robotic systems and nano-mechanical devices will be the biomolecular electro-mechanical hardware of future biomedical applications.","PeriodicalId":236431,"journal":{"name":"MatSciRN eJournal","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125382627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
