An alternative
approach to the extraction of structure functions in deep inelastic e-p
scattering at 5 to 20 GeV
N.
Ghahramany and M. Nouri
Abstract:
Two
structure functions W1 (x, Q2 ) and W2 (x, Q2
) are determined by using the cross sections measured in the deep inelastic
electron-proton scattering experiments at Stanford Linac in the energy range of
5 to 20 GeV. In this paper an alternative mathematical approach have been used
in such determination, resulting in a larger number of points in the graphs of
the structure functions.

Simultaneous
Spectrophotometric Determination of Copper and Nickel from Their Alloys using
2-Hydroxy-4-n-butoxypropiophenone Oxime as an Analytical Reagent
P. K. PATEL
Abstract:
2-Hydroxy-4-n-butoxypropiophenone Oxime (HBPO) forms 1 : 2 complexes
with Cu (II) and Ni (II) in the pH ranges 5.0 - 9.5 and 9.0 - 10.5 respectively.
The reagent has been found to be useful for gravimetric and extraction
photometric determination of Cu (II) and Ni (II). It has also been successfully
used for simultaneous spectrophotometric determination of Cu (II) and Ni (II)
from their synthetic mixtures containing 318 - 2860 µg of Cu (II) and 294 - 2642 µg of Ni (II) at pH 9.5. Analysis of a standard coppernickel alloy (B.C.S.;
180/2) [68.12% copper and 30.35% nickel], Indian coin - 10 paise of 1962 [74.3%
copper and 24.44% nickel], german silver [64.5% copper and 25.2% nickel] and
cupro nickel tubing [68.16% copper and 30.45% nickel] also showed that HBPO can
be successfully employed for quantitative determination of copper and nickel
from the alloy with an error of measurement of < 1 %.

A Kinetic study of
Oxidation of Chalcone by Quinolinium Dichromate
* P. MANIKYAMBA and K. ARUNA
Abstract:
The kinetics of
oxidation of chalcone by quinolinium dichromate is studied in aqueous acetic
acid medium in the presence of H2SO4. The reaction is
first order each in [chalcone] and [oxidant]. The reaction is acid catalysed and
increase in the percentage of acetic acid in the solvent mixture increases the
rate. A mechanism involving a slow attack of (QH)H2+CrO4
on chalcone molecule is giving benzoic acid and phenyl acetaldehyde is proposed.
TOPSAR Model for Bathymetry Pattern
Detection along Coastal Waters of Kuala Terengganu, Malaysia
Maged
Marghany, K.B. Yunus and Mohd. Lokman Hussien
Abstract:
This work
presents the application of inversion of the linear Kernal of Voltera model to
detect underwater bottom topography. The water depth simulated based on
the continuity equation of current movements. The result shows that Kernal
of Voltera model can produce a good description map of coastal water bathymetry.
The current movements are in range direction with coastal water bathymetry.
The current movements are in range direction with maximum speed of 1.3m/s which
flowed over water depth ranged from 10 to 20m.
Radarsat Modeling of Residual
Currents and their Effects on Oil Spills Spreading
Maged Marghany
Abstract:
Oil spill movements can be modeled from Radarsat image. Radarsat data
recognized as good tool for oil spills detecting and modeling. In doing
so, the finite element model of Doppler shift frequency was applied in order to
investigate water movements from Radarsat image. The ground data of Tidal
elevation was used to simulate the real current velocities. The simulated
current was correlated with current velocities. The simulated current was
correlated with current patterns modeled from Radarsat image. The residual
current in Malacca Straits are dominated by tide-forcing. In this study,
the oil spills transport model included surface spreading and the effects of
horizontal residual current movements.
The results show that the oil spills spread
as an ellipse in the direction of the major axis of residual current ellipse.
The residual current of tidal components suggested that the oil spill transport
in Malacca Straits is function of tidal flood towards the north direction.
It can be said that the modeling of residual current from Radarsat data could be
good tools for oil spill transport.

Activation energy parameters for the
hydrodynanic flow of the aqueous solution of 1,4 Dioxane and Acetonitrile under
magnetic field through a cellulose acetate membrane
Meena
Sharma* and Deepika Gupta
Abstract:
The enthalpy of activation ΔH*, the
entropy of activation ΔS* and the free energy of activation ΔG* have been
measured for the hyderodynamic flow of the aqueous solution of acetonitrile and
1,4-Dioxane through cellulose acetate membrane under the effect of magnetic
field. The enthalpy of activation ΔH* decreases with decrease in magnetic field
in both the cases ΔH* increases with increase in concentration and voltage, ΔS*
decreases with increase in magnetic field strength but the value of ΔS*
increases with increase in concentration and voltage. The value of free energy
of activation decreases as the concentration increases.

Quasi-elastic electron-deuteron
scattering and calculation of neutron electromagnetic form
factors at Q2=1.75 to 4.00 (GeV/c)2
N. Ghahramany, M. Vaez
zadeh Asadi and G. R. Boroun
Abstract:
Electric and Magnetic form
factors of neutron are calculated via electron-deuteron scattering at 1.511-
5.507 GeV energy using SLAC group data. The study of our results show that the
neutron electric form factor is not equal to zero; rather it has small value
indicating, in spite of the fact that total charge is almost neutral, there is a
nonuniform charge distribution within the neutron and magnetic form factor
follows the dipole fit.

Flow of an
electrically conducting incompressible fluid past a hot vertical porous wall in
the presence of transeverse magnetic field with periodic temperature
K. C. SARANGI and V. K. SHARMA#
Abstract:
An analytical solution of a free
convective flow of a viscous, electrically conducting incompressible fluid past
a hot vertical porous wall in the presence of transverse magnetic field is
obtained in the presence of constant suction velocity and span wise co
sinusoidal wall temperature. Approximate solutions of the equations of the
motion and energy have been obtained by the method of regular perturbation. The
effects of the Hartmann number on the functions affecting the mean velocity,
temperature field are discussed numerically and shown through graphs. The
expression of skin friction coefficient and Nusselt number at wall are derived.
The numerical values of skin friction and Nusselt number are presented through
table.

Abstract:
This paper
outlines the major findings on the pulp and paper industry. The strategy put
forward in this paper shows the energy consumptions and environmental
performance. The average energy consumption for Indian pulp and paper mill is 35
GJ/ton against 23GJ/ton in Japan, which has a similar pulp to paper ratio. The
average specific carbon dioxide emission from the sector is 2.39 tonne of paper
produced. The study is to identify and priorities major information gaps and
needs about the current trends of CO2 emissions, so as to access the level of
awareness of environmental issues and resources. The study is to identify
available incentives and capacity for industrial management and potential of
cleaner technologies and to examine and quantify the opportunity to promote
industrial management and cleaner friendly technologies.
