We describe an alternative method for realizing a carbon nanotube spin field-effect transistor device by the direct synthesis of single-walled carbon nanotubes (SWNTs) on substrates by alcohol catalytic chemical vapor deposition. We observed hysteretic magnetoresistance (MR) at low temperatures due to spin-dependent transport. In these devices, the

Ethics and morality is debatable. But the concept of ethics always relate to moral responsibilities.It is debatable due to different views and different interpretation on what is considered as unethical and immoral conduct. Sometimes certain acts are not unethical or immoral in certain countries but considered as immoral in the other country. Basic

Media optimization of RCI hybridoma cell culture for monoclonal antibody production was carried out in T -Flask experiment. The three identified important variables to affect the cell viability were studied. By using Central Composite Design of Response Surface Methodology(STATISTICA v 6.1) has shown that cell viability was mainly affected by gluta

Objective: To compare angioplasty (PTA), supervised exercise (SEP) and PTA + SEP in the treatment of intermittent claudication (IC) due to femoro-popliteal disease Methods: Over a 6 years period, 178 patients (108 men, median age 70 years) with angioplastiable femoro-popliteal lesions were randomized to: PTA, SEP or PTA + SEP. Patients were assesse

In today’s automation systems transducers are making core elements in the instruments and the circuits used for measurement, control and industrial applications. The task of a transducer is to reproduce a physical quantity as an electrical signal which with the help of conditioning circuits, is transformed into a form that suits a corresponding A

The major needs in machining are high material removal rate, good work surface finish and low tool wear. These objectives can be achieved by reducing tool wear using proper cooling system of the tool during machining. In the present work a tool has been modified to apply liquid nitrogen as coolant through a hole made in the tool so that liquid nitr

All control systems suffer from problems related to undesirable overshoot, longer settling times and vibrations while going form one state to another state. Most of relevant techniques had been in the form of suggesting modification and improvement in the instrumentation or interfacing part of the control system and the results reported, remain suf

In the present study an analysis has been done to evaluate the electrode wear along the cross-section of an electrode compared to the same along its length during EDM of aluminum and mild steel using copper and brass electrodes. In an overall performance comparison of copper and brass electrodes, we found that electrode wear increases with an incre

This paper attempts to model and design a simple fuzzy logic controller with Variable Reference. The Variable Reference (VR) is featured as an adaptability element which is obtained from two known variables – desired system-input and actual system-output. A simple fuzzy rule-based technique is simulated to show how the actual system-input is grad

The liquid properties such as buoyancy, pressure at a depth, relative electrical permittivity, electrical conductivity, thermal conductivity, absorption of radiation, liquid surface reflection of sound or light waves, are used to design the different types of liquid level transducers for liquid level measurement in any process industry. The contact
