This study includes the evaluation of the problem of seawater intrusion in Al-Bassa area in
2014 through chemical monitoring of a group of sampling wells, under certain condition
that were subjected to the area during the research, representing by
rainfall precipitation in
the study area was only 500 mm/ year, as a result in the suspension of irrigation from 16
October lake and reuse of many abandoned pumping wells.
This study founds an increasing in the salinity values in the Al- Bassa coastal area of
summer in 2014, ranging between(665.6-6432mg/l)after increasing daily pumping rates, in
addition to the increasing of chloride and sodium concentrations in most of sampling wells
water in conjunction with high salinity levels. In the fall, the salinity values ranged
between 490-950 mg / l. The geochemistry of Na/Cl indicates values less than 0.84 in
most water samples during the summer, while in autumn this percentage was higher than
0.84 in most samples ,to be an indicator for marine water.
This study aims to evaluate the effect of intrusion method on the
occlusal relationships during the Anterior Open Bite treatment by
applying Decortication and Low Level Laser by using posterior bite
block to intrude the posterior segment by analyzing study casts.
With the recent advances in the field of network security, a technique called
Intrusion Detection System IDS is developed to further enhance and make network secure.
It is a way by which we can protect our internal network from outside attack, and
can take
appropriate action if needed. Using intrusion detection methods, information can be
collected from known types of attack and can be used to detect if someone is trying to
attack the network. Many techniques are there to detect intrusion in a network like
signature matching, anomaly based and others.
The work presented here studies and compares the techniques used by intrusion
detection systems, and focuses on the signature matching technique. It discusses the open
source, free intrusion detection system Snort. Another open source intrusion detection
system Bro is also discussed. It compares these systems alarms against the open source
tool IDSWakeup.
Fibre optics have greatly developed over the past decades, making it usable in wired communication systems.
It has many advantages such as:
High channel capacity.
Interference immunity.
Low loss.
Security & Immune to intrusion.
That’s w
hy it became so popular in different types of usage.
This article discusses the security of fibre optics, proposes an intrusion detection system able to detect
different intrusion techniques, and specifies the intrusion point depending on modes and optical powers.
