Introduction The very first fully digital camera came into existence in 1975. The camera was created by the Kodak inventor, Steve Sasson. Sasson pieced together the camera and took the first picture which was of his lab assistant. The picture was recorded on a cassette tape and displayed on a television screen. The first digital cameras sold commercially were small and could fit in the palm of your hand. Now we have everything from small hand held cameras to larger cameras with changeable lenses…

New method of synthesis of oligoetherols with carbazole ring Renata Lubczak Abstract: The new method of synthesis of multifuntional oligoetherols with carbazole ring suitable for obtaining the polyurethane foams of enhanced thermal resistance was presented. At the first step of the synthesis the carbazole was reacted with excess glycidol to obtain the product of (n +1) functionality, where n is number of equivalents of glycidol reacted with carbazole. Carbazole reacts with glycidol without…

connected to the company’s wide area network (WAN). The WAN is set up with a T3 leased dedicated line running fiber optic cables. This line securely connects all three stores together forming their WAN. The T3 line connects to an optical router that then connects to the stores LAN. Each store LAN is set up with a 100 t-base fast Ethernet connection that is also fiber optic (Kudler, 2008). Fiber optic cables are faster than the copper cables, and the T3 line sends data rapidly. Each store…

While ubiquitous Internet access is extremely convenient and enables marvelous new applications for mobile users, it also creates a major security vulnerability—by placing a passive receiver in the vicinity of the wireless transmitter, that receiver can obtain a copy of every packet that is transmitted! These packets can contain all kinds of sensitive information, including passwords, social security numbers, trade secrets, and private personal messages. A passive receiver that records a copy of…

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…

Your Inner Fish by Neil Shubin Chapter Questions Chapter 1 – Finding Your Inner Fish 1.

CHAPTER-1 INTRODUCTION Concrete a manmade material widely and greatly used in construction Industry. This concrete is a mixture of adequate proportion of cement, water and aggregate. Hardening (or) strength of this material is obtained by the chemical action between water and cement. As the time increases the stronger it grows (i.e strength of concrete is directly proportion to its age).The durability, strength, versatility and other characteristics of concrete depends upon the properties and…
