Abstract-
For near infrared imaging of neonatal head surrounded by cerebrospinal fluid layer, we have developed an imaging modality, which uses perturbation Monte-Carlo estimation of Jacobian of the forward model for photon propagation. In this case, we have shown that the conventional techniques, which uses diffusion approximation for light transport in tissue, fails to give the reconstruction of tissue optical proper ....etc

BIOSORPTION OF METALS


SELECTION OF BIOMASS
While choosing the biomass for metal biosorption, its origin is a major factor .

Biomass can come from, activated sludge or fermentation waste from industries like those of food, diary and starch .

organisms coming from their natural habitats are good sources of biomass.

Fast growing organisms that are specifically cultivated for biosorption purposes


TYPES OF BIOMASS

Agricultural products

Seaweeds

Fungi and Yeast

Bacteria

SCATTERING PARAMETERS OF CIRCULATOR

SCATTERING PARAMETERS OF CIRCULATOR

AIM: To study the operation of ferrite circulator and hence measure
i. Insertion loss ii. Isolation ii. And to determining S parameters

EQUIPMENT: Microwave Source (RKO/GO), Isolator, Variable Attenuator, Frequency meter, Slotted line , Tunable probe with detector, detector mount with detector, VSWR meter, Circulator and Matched Terminations-2.

THEORY: The circulator is a multi port junction that permits transmission in certain w ....etc

Wide angle X-ray scattering (WAXS) is an X-ray diffraction technique that is often used to determine the crystalline structure of polymers. This technique refers to the analysis of Bragg Peaks scattered to wide angles, implies that they are caused by sub-nanometer sized structures.Wide angle x-ray scattering is the same technique as Small-Angle X-ray Scattering (SAXS) with the distance from sample to the detector is shorter and thus diffraction maxima at larger angles are observed.The technique is a time-honored but a somewhat out-of-favor tec ....etc

CONDUCTIVITY ,FERMI LEVEL ,
MEAN FREE PATH &
RELAXATION TIME
FOR TYPICAL MONO-VALENT METALS
IS SHOWN IN TABLE

The conductivity may be obtained experimentally .
Further we can get by using eqn given below
= ( n*Qe2 * )/me --(1)
but obtained may not be accurate but we will get an idea of magnitude of . In a monovalent metal no of free e- /m3 is equals the no of atoms /m3 . From table we find that relaxation time T is of the order of 10-14 sec .Thus we can say that T is extremely small f ....etc

The Structure of Metals



Crystal Structure of Metals

Common crystal structures for metals
Body-centered cubic (BCC) - alpha iron, chromium, molybdenum, tantalum, tungsten, and vanadium.
Face-centered cubic (FCC) - gamma iron, aluminum, copper, nickel, lead, silver, gold and platinum.
Hexagonal close-packed - beryllium, cadmium, cobalt, magnesium, alpha titanium, zinc and zirconium.

electrical resistivity tomography ppt

Abstract
Electrical Resistivity Tomography (ERT) has become one of the most applied and user-favourable geophysical technique in geomorphological research. Multiple character of the technology using various electrode arrays significantly reduces measurement time and is suitable for applications even in hardly accessible mountain areas. ERT can be used for various problems concerning slope deformations and accompanying landform assemblages. Our study shows that the best results are obtained in sites with hi ....etc
