In this work the electrochemical behavior of Para-nitro aniline
and metoxy benzealdehyde was studied by cyclic voltammetric
method on glassy carbon electrode in alkaline medium . It was
found that the Para- nitro aniline needed five electrons to reduce to
the azo group.
In this paper, we propose modifications to TCP by
introducing adaptive delay and loss response (TCP-ADaLR) to
mitigate the adverse effects of satellite link characteristics.
The goal of all prosthetic treatment is to obtain a satisfying
functional and esthetical oral status. Successful treatment outcome
following prosthetic treatment relies on healthy hard tissues but
also on healthy soft tissues. The aim of this study is to
comparatively assess the clinical and biochemical parameters in
gingival sulcus around the teeth received zerconium ceramic
crowns with supra and sub-gingival crown margin position.
This paper presents an accurate mathematical model of threephase
induction motor for both transient and steady-state studies. this
model takes into account the network harmonics, Skin Effect and
Stator and Rotor Magnetic Saturation. and to be able
to present the
real motor and its internal physical phenomena better than the
existing classical models.
This paper presents the monitoring horizontal and vertical displacements of railway
which heavy cranes run on using special geodetic techniques for the purpose provaiding
rialway stability and safe working cranes on it. To quaranty that heavy crane
s work safly, a
rialway should be just horizontal– a small error of milimeters leveling is allowed according
to working conditions for cranes. A rialway shoud also maintain its spaces to facilitate the
crane motion on it. Monitoring railway vertical displacements involve measuring the
relative vertical displacements of target points that are distributed along the railway in two
cases: static and dynamic. vertical displacements determined by precise leveling which are
performed using digital high accuracy level. The precise leveling measurments of target
points have been connected to stable benchmark that are located in surrounding terrain of
railway for purpose of further studies. In this paper the alignment method was used to
monitoring the railway horizontal displacements using digital rulers and total station
provided by a prism fixed forcely on the railway. This is done by measuring the small bias
angles of the targat points which are distributed along the railway. This research has
illustrated the efficiency of alignment method in order to calculate the horizontal
displacements of railway axis.
In this article we study two classes of contact metric three manifolds,
where first we investigate the necessary and sufficient condition for the contact
metric three manifold to be partially pseudo- Ricci-symmmetric manifold of
constant type.
We
find also two relations that the 3-dimensional (k,m,n ) _ contact
metric manifold has to satisfy to be partially pseudo- Ricci-symmetric manifold
of constant type.
The Study aimed at recognizing the problem of the stable and the
changeable and its educational dimensions. To achieve this aim, the study
try, through its use of a comparative deconstruction course, to clarify that
there are two opposite philosop
hies that are related to educational work.
The first philosophy sees that the basic principles of education recur and
never change, whereas the second philosophy sees that the only way for
arrangement for a changeable society is to face the educational thought
that believes in continuous renwal to set up the experience. The study
introduced a suggested conception for educational philosophy that forms,
in its abstract, a moderate stance.
