amount, and the process is repeated. In order to build an object the controlling drawing for each layer changes very slightly.
Typical standard manufacturing methods are subtractive, that is material is removed from a base form by machining with a lathe, with a drill, by cutting, planing or broaching. By contrast 3D-printing is an additive process, because material is added, layer by layer.
5.2 Drug Delivery System
5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug
piezoelectric crystal.
Quartz Crystal Microbalance= A poly film-coated piezoelectric quartz crystal sensor
The range of resonance frequency= 10~30 MHz
The detection limit = 10^-12 g for analyte molecules( according to Sauerbrey’s equation )

Surface Acoustic Wave sensor in which the acoustic wave on the surface of the piezoelectric crystal, launched and received on t
For example, thanks to satellite system, it can find heavy traffic area and find alternative routes very fast.
2. Gmail: Google developed the Nexus one. So Nexus One share features of Google. For example, Nexus One is compatible with Google Mail (Gmail). As a result, users don't have to carry heavy laptop computers to send and receive e-mails.
3. Browsers: People tend to use a smart phone to br
interaction in which information processing has been thoroughly integrated into everyday objects and activities. In the course of ordinary activities, someone "using" ubiquitous computing engages many computational devices and systems simultaneously, and may not necessarily even be aware that they are doing so. This model is usually considered advancement from the desktop paradigm.

● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for

Siemens composes of portfolio focusing on environment such as Reproductive energy wind power generation and solar heat power generation. Also, environment-friendly technologies- water treatment tech and air pollution control tech- apply to all business. Besides, Siemens considers efficiency of energy technology. It evolves complex fire power plant, driving system for i
is obtained through neuromarketing. Understanding how and why consumers feel various emotions is the most essential step for all marketing strategies, since they can turn out to be a great failure if customers do not empathize with them. In a sense, neuromarketing, dealing with emotions and subconscious of consumers, encompasses virtually all kinds of marketing trends to come in the future.
