Title: Synchronous Oscillator Using High Speed Emitter Couple Logic (ECL) Inverters
Authors: Chakraborty, B; Pal, R. R.
Abstract: This paper presents a synchronous oscillator using a high speed low
voltage Emitter Coupled Logic (ECL) inverter. Using the positive
feedback the locking range increases, compared to the oscillator
without any positive feedback. A maximum improvement (increase)
of locking range of around 172% was obtained from circuit
simulation as well as from practical circuit, using discrete
components. Here the supply voltage requirement is 2.1 volts.

Title: Low Molecular Mass Gelators of Organic Liquids
Authors: Maity, Gopal Chandra
Abstract: In recent years there has been a considerable interest in developing new
types of low molecular mass organogelators because of their potential
technological applications. Several classes of low molecular weight
compounds form stable and efficient gels with various organic solvents at
low concentrations. One-component and two-component gelators are
grouped separately. Each group is self-assembled by various noncovalent
to form various structures with nanometer and micrometer dimension

Title: Study of Speed Enhancement of a CMOS ring VCO
Authors: Chakraborty, B; Pal, R. R.
Abstract: Positive feedback has been added to a fully differential CMOS amplifier.
With the introduction of positive feedback, the delay time reduces and
the speed of operation increases. An even or odd number of stages can
be cross coupled or directly coupled to form a ring Voltage Controlled
Oscillator or Current Controlled Oscillator (VCO/CCO). Pspice
simulation shows an improvement (increase) of speed of around 167 %.
Instead of using positive feedback if we use negative feedback then also
the speed improves but it requires a higher value of feedback resistance,
which is not favoured in integrated circuit fabrication. Here the typical
supply voltage requirement is ±2 volt. Using this amplifier some
applications have also been discussed.

Title: Effect of Magnetic Field on Pulsatile Blood Flow Through an Inclined Circular Tube with Periodic Body Acceleration
Authors: Sanyal, D C; Das, K; Debnath, S
Abstract: A mathematical model has been developed for studying the
characteristics of blood flow in a rigid inclined circular tube with
periodic body acceleration under the influence of a uniform magnetic
field. The blood is supposed to be couple stress fluid. Finite Hankel and
Laplace transforms are used to obtain the analytical expressions for
velocity profile, flow rate and acceleration of blood. The flow velocity
deviates with various parameters such as Hartmann number, gravitational
parameter, body acceleration, inclination angle, time etc. and this
deviation of flow velocity can be regulated by a proper use of magnetic
field.
