The Avanah Formation (Middle Eocene) was studied in the Haibat sultan section at Bina Bawi Anticline, Northeast of Erbil city within the Iraqi Kurdistan region. The field observation indicated that the formation occurs as Carbonate interbeds within the lower and middle parts of the Gercus Formation, which consists mainly of light yellowish to creamy color, well-bedded, marly, and dolomitic limestone with some intercalations of sandstones and marls reaching about 32 m thick characterized by lateral variations in facies and thicknesses. A petrographic study of 16 thin slices of carbonate rocks indicated that most of the matrix is composed of micrite, with a few microspars. Foraminifers, dasycladacean green alge, and Ostracods make up the skeleton grains. Non-skeletal grains mainly include peloids, intraclasts, and extraclasts. Depending on detailed microfacies analysis in the current study, five main microfacies and fourteen submicrofacies were discovered. The total of all petrographic, facies and textural investigations indicates that the Avanah Formation in the Haibat Sultan area was deposited in the shallow marine inner platform within subtidal, intertidal, and supratidal environments

Several algebraic structures have been studied by many authors to discuss the relationships among them. This article aims to study two algebraic structures, namely semigroup and BA-algebra, by combining them in one form, namely BA-semigroup and investigate some of its properties. This paper studied the BA-sub-semigroup, an ideal and BA-homomorphism of a BA-semigroup with some of their properties. Some examples are given to illustrate the results.

To interpret the provenance 0f Injana Formation, 20 sandstone samples of Injana Formation were collected from Zawita and Dekala areas north Iraq (10 for each sections ), then thin section have been done sildes. The petrographic study showed that the sedimentary, metamorphic and igneous rock fragments, quartz (mono&polycrystalline) and feldspars (microcline, orthoclase and plagioclase) make up the main grain components of the sandstone. Carbonate cement is more common cementing minerals, and the matrix is subordinate. The percentage of mono-quartz and sedimentary, igneous rock fragments are greater than the amounts of feldspar and poly-quartzand metamorphic fragments. A diagenetic processes were represented by the carbonate, iron oxides and evaporite cements, as well as compaction, cementation, and dissolution. The majority of the rocks of Injana Formation’s provenances are sedimentary and igneous, with minor amounts of subordinate metamorphic rocks. These sandstones are considered to be immature and classified as immature Litharenites type. The tectonic provenances that are extrapolated from petrographical results are transitional and lithic with effect of uplifting of Alpaine oroging recycled origin which are derived from the order rocks during the Miocene age.

This study included an assessment of the hydrogeological conditions of the Mishraq sulphur fields before production, by measuring groundwater levels in (11) wells in Mishraq-2 in 2021, as well as the information of wells obtained, which are (12) wells in Mishraq-3, (68) wells in Mishraq-1. Groundwater levels ranged between (187.71-205.80) m in Mishraq-1, while in Mishraq-2 it ranged between (189.19-196.26) m, as for Mishraq-3 the levels were between (186.4-194.98) m. The contour maps were drawn for the movement and levels of groundwater, showing that the direction of groundwater movement in Mishraq field-1 is from the west and northwest to the east, with a slight slope towards the southeast, towards the Tigris River, while in the Mishraq field-2, we notice that the direction of groundwater movement is From the east to the west, that is, toward the Tigris River, as for Mishraq field-3, it was found that the direction of movement is from the southeast toward the northwest, that is, toward the Tigris and Great Zab rivers. So it can be said that the Tigris and Great Zab rivers are the two drainage areas in these three fields. The hydraulic properties were analyzed in (44) wells in the three Al-Mishraq fields. Where the values of Transmissivity (T) in Mishraq field-1 ranged between (24.4-1557.5) m2/day, as for Mishraq-2 it ranged between (23-96.91) m2/day, while in Mishraq-3 it ranged between (10.5-4002) ) m2//day, and the hydraulic conductivity (K) ranged between (0.26 -14.68) m/day in Mishraq field-1, as for Mishraq-2 it ranged between (0.7-4.2) m/day, while in Mishraq-3 It ranged between (0.37-119.09) m/day.

In this paper, the general formula of the Crank-Nicolson Numerical Method was derived and applied to solve the heat diffusion. The same problem then has been solved using ADI numerical method. The results of the Crank-Nicolson numerical method were compared with that of the ADI numerical method. The comparison results revealed that Crank-Nicolson is more accurate than the results of ADI at the initial steps of the problem solution.

It is one of the principal genera that belong to the group of ‘lactic acid bacteria’ (LAB), which also includes Streptococcus and Lactobacillus. The study aimed to detect Enterococcus spp. bacteria using molecular diagnostics .Twenty-one isolates (21%) from 100 samples belonging to Enterococcus spp. were obtained. Three isolates belonging to (two) Enterococcus avium (9.52%) one of them isolated from Kaymak and the other from yoghurt, the other one was (one) Enterococcus casseliflavus (4.76%) which isolated from Ricotta (Made by buffalo milk). After diagnosing by Vitek-2 system of Klebsiella pneumoniae bacteria and detecting its biofilm formation by ‘Congo Red Agar’ method with antibiotic test, the effect of the Enterococcus avium and Enterococcus casseliflavus (supernatants and pellets) on its biofilm formation was tested. Moreover, when compare; to the control group, the effect was highly ‘significant’ (p.0.0069).

The primary goals of transportation agencies and researchers studying traffic operations are to ease traffic and increase road safety through the use of vehicular ad hoc networks. Agencies can't achieve their goals without reliable and consistent data on the current traffic situation. The Level-of-Service (LOS) index is a helpful measure of freeway traffic operations. Conventional fixed-location cameras and sensors are impractical and expensive for gathering reliable traffic density data on every road in large networks. Flow data is a new, low-cost option that has the potential to boost safety and operations. This study proposes an algorithm for hourly LOS assessment by incorporating flow data provided by the MIDAS (Motorway Incident Detection and Automatic Signaling) system. The proposed algorithm uses machine learning techniques to classify LOS data based on the flow of traffic. The input features that are subject to prediction are a group of technical indicators. The real-world LOS was determined by analyzing data from stationary sensors. The outcomes demonstrate that technical indicators can be utilized to enhance the accuracy of LOS estimation (Random Forest= 93.1, k-nearest neighbors = 92.5, and Support Vector Machine = 91.4). The current work introduces a novel approach to the selection of technical indicators and their use as features, which allows for highly accurate short-term prediction of LOS estimation.
