The sample program began in May 2023 and includes the examination of several heavy elements, including but not limited to (As, Cd, Cu, Pb, Va, Ni, Zn, Bo, Cr, Co, Li, Mn, Se, and Ag)The essential goals of this research are to find that the samples have concentrations within the acceptable limits as prescribed in Iraqi drinking water standards. The average Heavy metal Pollution Index (HPI) concentration is 955, which is considerably less than the crucial index value of 100. The percentage of groundwater samples that exceeds the 100-index value is 5%, indicating that the water is completely unsuitable unfit for drinking, while 90 percent are rang from excellent to very poor quality according to HPI. The MI concentration was 0.16 with 88.6 % percent of groundwater samples were found to be very pure water class. The results show that the groundwater in the Akre-Bardarash basin of wells 1,2, and 3 is highly polluted in the northeast part, and wells 22 and 30 are also highly polluted in the south-east part. All of the wells mentioned above are unfit for human consumption. The impact of human activity and industrial activity on the study area has played an important role in the pollution of groundwater quality in the northeast and southwestern parts of the Akre-Bardarash Basin. According to the findings of the current study, it can be concluded that the water can be used safely for drinking without any negative effect on human health, except wells 1,2, and 3 in the northeast part and wells 22 and 30 in the southwest part.","PeriodicalId":23142,"journal":{"name":"Tikrit Journal of Pure Science","volume":"27 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141357363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given that the Dibdibba hydrogeological aquifer is thought to be the main source of water in this region, this site is chosen for performing the hydrogeological assessment. The study included 60 wells located on the west of the study area in Najaf Governorate. In these wells, the groundwater depths were measured in the field at the beginning of December 2021. The water stream was between 7.8 and 37.7 meters above the sea level, while the well depths ranged from 2.83 to 34 meters. Then, the spatial distribution of depths and water streams was mapped. Many wells were left by farmers because the water stream had gone down and the depth of the water had increased. The flow net of groundwater was determined to have two directions. The first direction was from the west to the east, and the second one was from the west and northwest to the southeast. The hydraulic properties of the Dibdibba aquifer in this study area were extracted by pumping tests. The experiments were carried out for five wells distributed over the area. The data was replaced with input into software for pumping tests, then analyzed by Newman's and Jacob's corrected methods for unconfined aquifers. Transmissivity values in experiments (T) ranged between 348 and 596 square meters/day, while hydraulic conductivity ranged between 14.1-22.5 m/day. The specific yield (Sy) equivalent to the storage coefficient in a confined aquifer was between 0.006 and 0.0302. The results of pumping test showed that the aquifer was of unconfined type according to the Neuman's and Jacob's corrected curves. In addition, the hydraulic property values were similar in all experiments with a slight difference, which may be related to the differences in saturated thickness, total depths, hydraulic gradient, and properties of rocks and sediments.","PeriodicalId":23142,"journal":{"name":"Tikrit Journal of Pure Science","volume":"257 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139159962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This formation typically has low shale content at the BN-1 well. At the same time, in the MW-2 well, the middle part of the studied formation is dominated by shaly and shale intervals, possibly affected by the Sarmord and Balambo depositional environments. Although the upper part of Qamchuqa Formation is mainly composed of dolomite with minor dolomitic limestone, marl and shale are occasionally present. Furthermore, porosity values are commonly less than 15% in both wells; nevertheless, there are a few intervals where porosity significantly increases. The formation at the BN-1 well has a higher porosity than the MW-2 well. Moreover, the secondary porosity is relatively low as 4.0% at the MW-2 well, while in the well of BN-1, it ranges between < 4.0% and 7.5%. The measured permeability of the formation suggests good permeability. According to the shale volume, porosity, and permeability, the upper part of Qamchuqa Formation is subdivided into three reservoir units. RU 1 at the MW-2 well and RU 2 at the BN-1 well have the most substantial reservoir properties. However, the lowest reservoir quality appears within RU 1 of the BN-1 well and RU 2 at the well of MW-2. Additionally, residual hydrocarbons constitute an extensive fraction of the pore spaces, while tiny portions of the moveable one can be discovered along all reservoir units of the formation. Finally, considering the hydrocarbon movability of the MW-2 well, the upper part of Qamchuqa Formation is defined by primarily movable oils in RU 1 and 2. In contrast, moveable oils are detected in almost all of the reservoir units of the BN-1 well.","PeriodicalId":23142,"journal":{"name":"Tikrit Journal of Pure Science","volume":"21 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139158060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

X-ray diffraction (XRD) showed that the width of the peaks decreases with increasing the ratio of doping with copper. This leads to an increase in the crystal size and in the intensity of the copper peaks, as well as a gradual decrease in the intensity of the titanium dioxide peaks. The results of the atomic force microscope showed that increasing the inoculation percentage leads to an increase in the surface roughness and the average grain diameter, and thus an increase in the growth of the particle size. The electrical tests (Hall effect) showed that the prepared films are of (n-type) and that the concentration of carriers (n) increased with the doping ratio, while the mobility values (µH) decreased directly with the increase in copper.

The process of tracking people and studying their behaviour could result in a large set of information that can help researchers in studying reactions. The techniques of detection and tracking the movement of people are used in the sports field, where the athlete's movement is studied and analyzed within the game. Based on the information obtained from the process of tracking the athlete's movement, it is possible to improve the playing performance as well as avoid injuries and choose the best playing strategy. In some games, the accuracy of athlete's performance is a measure of the points given to the athlete's like gymnastics. This study reviews a set of articles that relied on computer vision as well as deep learning in the process of distinguishing and analysing the athlete's movement. The articles are confined to the years from 2015 to 2022, dealing with different indoor and outdoor sports. Certainly, the study of indoor games is better because the influence of weather conditions is less than that of outdoor ones. Reviewing the articles demonstrates that relying on computer vision systems is more effective than relying on human rulers, as humans are more prone to error. As for relying on the deep learning techniques for detecting the object, the results are very positive, due to the correct detection of the object. The results of the analysis of this object will be more accurate.","PeriodicalId":23142,"journal":{"name":"Tikrit Journal of Pure Science","volume":"11 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139158875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
