Erbil Polytechnic University Announced The Internationalization Of The Polytechnic Journal in a ceremony

On Wednesday, the 3rd of May, 2023, in the presence of the Rector of the University, Prof. Dr. Edrees Muhamad Tahir Harki, a number of presidents of Kurdistan universities, the General Director of the Divan of the Ministry of Higher Education,the Ministry of Higher Education and Scientific Research Consultants, a parliament member, the Vice Rectors, teachers and researchers of the Erbil Polytechnic University the international journal introduction ceremony was held.

At the beginning of the ceremony, the Rector of the University, Prof. Dr. Edrees Muhamad Tahir Harki welcomed the guests and explained the importance of this strategic and unique step. His Excellency said: “today, we are pleased to celebrate with you the launch of the Polytechnic Journal, which is registered on the platform of (Elsevier Digital Commons).

Ladies and Gentlemen, if we look at the universities of the world in general in recent years, they made many changes in the university system of higher education as we see that these universities follow a culture of internationalization, and those universities that have moved towards internationalization are far ahead of those that have not been able to internationalize their universities.

In fact, the internationalization of a regional or local university requires a radical and permanent change in the philosophy, direction and strategy of the university. So, the university leadership should use this philosophy. We as the Erbil Polytechnic University have continuously worked on internationalization of the university in many areas. If you want to internationalize a university, you must work with all institutions in the university and programs and conduct scientific research jointly with other universities.

At the Erbil Polytechnic University, we aim to step forward to enable researchers of our university and universities in Erbil and Kurdistan Region in general to be able to do their research internationally, because we have master’s and doctoral students It is a very good thing to do. Because of being evaluated in a local journal and locally have been read it may not be very visible. For this reason, we thought it is  necessary to take this initiative and register the Polytechnic Journal on the Elsevier platform to make it easier for our researchers to internationalize their research.

We hope that we can work on how to make our university international in the future. I welcome you again and we hope that this journal open be a new gate for all teachers and researchers of Kurdistan universities.”

Then the Vice Rector for Scientific Affairs and Higher Education, Asst. Prof. Dr. Nageb Toma Bato briefed the audience on the history of the Polytechnic Magazine and explained the details and working methods in the past and present, as well as the stages that the magazine has passed through.

Later, Asst. Prof. Dr. Karwan Wasman and Dr. Rawaz Ahmad Kurda jointly discussed the registration and implementation of the journal’s work in the platform and how to publish research and registration of researchers were explained.

Then His Excellency the University Rector Prof. Dr. Edrees Muhamad Tahir Harki awarded the researchers with a free of charge publishing of their research in this journal.

  • Abstract

    High-strength concrete is used to reduce the size of the beams in addition to enhancing the strength,
    this leads to overestimated cost in comparison with normal-strength concrete while using normal-strength concrete leads to the overestimated amount of concrete (layer size) of the beam section. For
    balancing the condition between the cost and size of beams, the benefit of both materials is used, by
    using beams in two layers, high-strength concrete in the compression zone (top layer), which is more
    beneficial for beam strength, and normal strength concrete in tension zone (bottom layer), which is no
    need using high strength concrete the in-tension zone. This study investigates the flexural and shear
    behavior of reinforced concrete beams consisting of two layers with different concrete strengths
    (grades), for beams with and without shear reinforcement (stirrups), considering the effect of shear-span ratio, layer thickness, layer compressive strength, and the overlap time casting of the two layers.
    The experimental program consists of a total of nineteen reinforced concrete beams of dimension (125
    mm x 250 mm) with a total length of 1200 mm, the beams are reinforced with longitudinal
    reinforcement (4Ø12mm) and using (Ø8mm) bar as transverse reinforcement (stirrups). The
    experimental results show that the crack pattern of the two-layer reinforced concrete is closer to the
    crack of the control beam with one layer. Increasing the compressive strength of the concrete of the
    top layer, the ultimate failure load increased by (8.35%, 15.6%, and 18.85%), with respect to the
    (control beam) with the full depth of normal concrete. By increasing the high-strength layer thickness,
    the value of shear strength (Vc) and ultimate shear strength (Vu) increased linearly. The casting overlap
    time of up to (60 min) can be used for casting two-layered reinforced concrete beams, which is
    recommended, beyond this time the strength of the shear strength (Vc) and, ultimate shear strength
    (Vu) decreases. With increasing the shear span ratio (a/d) from (1 to 1.5 and 2) the ultimate load
    failure decreased by (33% and 50%). The shear strength capacity decreases with increasing stirrup
    spacing.
    Key Words: Two-layer RC beams, HSC beams, NSC beams, Shear strength, Ultimate shear
    strength.

  • ABSTRACT

    The reason for using composite materials across a variety of sectors is their light

    density and consequently, this study's goal is to enhance the mechanical and

    physical properties of polymer composite materials. To do this, two types of

    polymer epoxy resin used as a matrix and reinforced with various fibers, including

    mica and pinecone fiber as natural and glass fiber as synthetic fibers. Each fiber

    added to the strength of epoxy resin by 15%, and creating hybrid composite by

    combing mica and glass fibers; also glass and pinecone fibers at different wt%

    (10:5, 7.5:7.5, and 5:10). Mica and pinecone fiber were also combined at wt%

    (7.5:7.5). Due to mica fiber being used here to reinforce polymer composites for the

    first time so three different forms (long fiber, powder and particle form) are used

    and compared the results. Pinecone fiber used previously but no one mixed it with

    glass fiber and these types of epoxy. Each sample was created using the hand lay-up

    approach. The bulk density has been measured as a physical property, and

    mechanical properties (tensile strength, flexural strength, and impact energy) have

    all been carried out in accordance with ASTM standards.

    Composite materials reinforced by glass and mica fiber in long fiber unidirectional

    form were utilized. Noticing that mica fiber had a role in lowering bulk density to

    2.76% for sikadur epoxy and 1.93% for master brace epoxy. Nevertheless, glass

    fiber increased bulk density. Both fibers enhanced mechanical properties; however,

    glass fiber has a bigger influence rather than mica fiber, even though mica fiber

    may also provide improvements from 26% to 67% to each of them.

    Also composite materials reinforced by unidirectional glass fiber and pinecone

    fibers as reinforcement uses while using powdered pinecone. Pinecones

    significantly impact reducing bulk density; for example, both epoxy had decreases

    of 6.947% and 4.3%, respectively. In terms of mechanical properties pinecone fiber

    had a decline effect, it saw a 5-26% decrease in the tensile and flexural strengths, 39-51% for impact energy, and however, when coupled with glass fiber, it had

    positive results.

    Using mica as (long fiber, particle, and powder), all enhanced bulk density by 2-

    4%, but the effect was greatest when pinecone was added. In terms of tensile and

    flexural strength, all of them improved by 10–60%, but the long fiber show greater

    effect. However, impact energy increased by 26–50%, the powder form achieved

    more value, but when mixed with pinecone, the impact energy decreased roughly 25

    to 30 % comparing with the neat epoxy
