Blended Learning (BL) is the use of both offline and online methods for teaching and learning; it
allows for a planned and deliberate embeddedness of online learning into the education system and tests its
applicability alongside offline learning, which ensures adaptability to emerging challenges and the
upskilling of the digital capabilities of Iraqi youth. This approach was a serious try to improve the education
and E-learning and it indeed had a dramatic effect as it worked to promote the general well-being of learners
in Iraq. This paper investigates and presents a comparison between the E-learning applications during BLA
(in term of their features, flexibility, ease of use, advantages and disadvantages, and privacy and security).
The outcome of the study was relied on a questionnaire made in various Iraqi universities. A total of 100
people participated in the questionnaire, divided into two groups: students and lecturers. The results showed
that most lecturers and students prefer Google Meet. Google classroom and Zoom were the second popular
applications whereas Microsoft Teams was the least choice for both groups.

In this paper, URUK, a discrete four-dimensional chaotic map, is proposed for secure
communication. The 0-1 tests, the Lyapunov Exponent (LE) tests, and the National Institute of Standard
and Technology (NIST) tests, which are typically used to verify the randomness of bits, are employed to
evaluate the dynamic behavior of the system based on a variety of criteria. Based on the results of tests
demonstrating the system's characteristic chaotic and random behavior, it is reliable for use in covert
communications and image encryption.

It should be noted that there is a joint work between biomedicine such as forensic medicine and
information technology through the use of information technology technologies in all fields, including
determining the of DNA profile. One of the leading biotechnologies in this field is data mining techniques.
There are many ways to identify disaster victims, such as fingerprints, dental record and DNA profile
matching. DNA matching is a highly accurate identification way that does not need specific parts of the
victim's body. Deoxyribose Nucleic Acid (DNA) is the basic elements that make up an entire section of a
human. The core elements store unique information for each individual and will be passed on through
generations. DNA also helps in identifying the father in paternity testing,. The limitation of applying DNA
matching for disaster victim identification lies on expensive and time consuming process. To address this
situation, in this paper, we performed a method to measure the confidence of matching of human DNA
profiles identification using Association Rule Classification System is proposed. In this Classification
system, DNA profile data is used as an input that stores human identity along with its DNA profile. advisable
information or good patterns from present datasets for certain objective. The results were satisfactory and
characterized by large percentage and high accuracy. Finally, performance of this system is evaluated and
in turns the proposed

Considering the huge amount of information, it becomes so difficult to deal with and
understand only in condition they were organized, classified and saved as data base that can be deal with
automatically and to make use of it without interfering with its meaning and significance. Here comes the
need to invent new methods and systems to save such information and deal with. An example of such
systems is Management Information System and Geographic Information System. The ability of geographic
information systems to prepare the geographic database and represent it as digital maps is verified by
processing mineral data. This research aims to produce digital maps of mineral materials in Iraq by
converting a paper map (geological map) at a scale (1:1000000) into a digital map using the survey process
and modifying the coordinate system for this map using the georeferencing process. Then the layers are
extracted from this map using the digitization process, and these layers are represented, and the proportion
of these materials on these layers is represented as a circular sector. The purpose of a geodatabase is to
create features in GIS datasets and to determine the relationship between features that are shown on maps
as layers, where each layer represents a specific type of feature that was used for spatial analysis.

The study aimed to review the experiences of others in e-learning from different universities in
Iraq and countries around the world about facing the Covid-19 and how to face the crisis in the educational
field and come up with positive outcomes to advance the educational reality. The researchers used an
electronic questionnaire (Google Form) to collect information from (152) male and female students, the
questionnaire included (15) questions about e-learning, and the positive answers supported the success of elearning
in getting out of the Covid-19 crisis with satisfactory positive results.

A bio-organic coating was created familiar the biological system by extracting hydroxyapatite from
the original natural sources, including eggshells, fish bones, and cockle shells. Natural polymer extract from
Aloe Vera, it was used as the basic material for the coating and natural hydroxyapatite was added. In order
to reduce the impact of metallic within the biological system and improvement the cell viability of metallic
implants.

The security of image transmission is an important issue in digital communication. As well as it is
necessary to preserve and protect important information for several applications like military, medical and
other services related to high confidentiality over the Internet or other unprotected networks. In this paper a
proposed encryption scheme was introduced that using Lorenz system with a circular convolution and
discreet cosine transform (DCT). The diffusion process was achieved using three levels of Arnold transform
permutation: - namely, block level, inside each block and pixel level. The image was divided into blocks of
sizes 8x8 pixels and shuffle by applying Fisher-Yates permutation image pixels. The DCT was applied to
each block and multiplied by the H kernel matrix to achieve the circular convolution. Next the logistic map
is used for diffusion to get the cipher image. A new key generation method is applied in order to produce
the key values for generating the chaos numbers sequence. Finally applying the discreet wavelet transform
(DWT) to the image will produced four quarters (LL, LH, HL and HH). The cosine of each pixel in the LL
and HH quarters were computed. The sine of each pixel in the LH and HL quarters were also computed in
order to generate the keys for the chaos sequence. By using this way of keys generation in every image, the
differential attack possibility will be negligible.
