Three-phase induction motors are widely used and one of the factors that confirm the reduction of their performance is the presence of harmonics in their voltage supply. In this paper, the impact of non-sinusoidal supply voltages on the steady-state performance of different NEMA designs of squirrel cage induction motors (SCIMs) is presented. It presents the analytical modeling based on the equivalent circuit taking into consideration the skin effect impedance that incorporates the skin effect on the rotor bars, which is used to investigate the motor performance under such conditions. The importance of this study is that it compares all NEMA designs in terms of electromagnetic torque, efficiency, losses, power factor, stator and rotor currents, and derating factor under a distorted supply voltage that is polluted by the most significant odd harmonic orders at adjustable levels in the range of (0–25) % of THD<sub>v</sub>%. The obtained results are compared and validated with the system employed by using MATLAB/Simulink software.</p> Nihaya Abdulghafoor Othman, Hilmi Fadhil Ameen Copyright (c) 2023 Nihaya Abdulghafoor Othman, Hilmi Fadhil Ameen https://creativecommons.org/licenses/by-nc-sa/4.0 https://zancojournal.su.edu.krd/index.php/JPAS/article/view/320 Tue, 20 Dec 2022 00:00:00 +0000 Modelling Radial Oscillations of a Bubble in a Spherical Liquid-Filled Elastic Solid https://zancojournal.su.edu.krd/index.php/JPAS/article/view/356 <p>In this paper, equation of a spherical bubble oscillations in Newtonian and viscous fluid with considering compressible fluid flow in a spherical liquid-filled elastic solid was developed.

The directivity, gain, efficiency, bandwidth, VSWR, S11 and 2D-radiation pattern for each mentioned triangular patch shapes are computed utilizing CST and HFSS method. The computed results reveal generally that the ETMPA provide better radiation performance whereas the OTMPA displays lower antenna radiation parameter values compared to the other considered ones. In addition, the antenna parameters of ETMPA with the use of coaxial probe fed are also simulated and the results are compared to those previously achieved experimentally and theoretically by other researchers. Generally, a good agreement between mentioned antenna parameter results is displayed and reliability of those achieved by CST with inset fed techniques is clearly observed. Moreover, the overall antenna parameter obtained, respectively, with CST and HFSS techniques for inset fed ETMPA are S11 (-28.68, -20.64), VSWR (1.076,1.20), gain (5.82, 6.29) dB, directivity (6.85, 7.09) dB, bandwidth (0.452, 0.369) GHz, efficiency (78.9%, 83.2%) and with a small antenna size of about (3.88 mm<sup>3</sup>) which is most reliable for 5G technology application systems.</p> Bushra Adnan Rahman , Sattar Othman Hasan Copyright (c) 2023 Bushra Adnan Rahman , Sattar Othman Hasan https://creativecommons.org/licenses/by-nc-sa/4.0 https://zancojournal.su.edu.krd/index.php/JPAS/article/view/486 Tue, 20 Dec 2022 00:00:00 +0000 Influence of some Bio chars and organic fertilizers on some biological parameters of sweet corn (Zea mays L.) at Sulaimani Governorate, IKR. https://zancojournal.su.edu.krd/index.php/JPAS/article/view/324 <p> This study was conducted in July 2021 until October 2022 at kanipanka research farm, Sulaimani governorate, IKR with GPS readings of 35<sup>0</sup> 22’ 25.3<sup>”</sup> N, 45<sup>0</sup> 43<sup>’</sup> 24.5” E to test, the influence of five levels (0, 14, 28, 42 and 56 ton ha<sup>-1</sup>) of some treatments such as control (a1), rise husk bio char (a2), oak charcoal (a3) and poultry manure (a5) which equivalent to 0, 0.4, 0.8, 1.2 and 1.6% w/w% of soil, also five levels (0, 12.5, 25, 37.5 and 50 kg ha<sup>-1</sup>) of Humic acid (a4) to examine the quantity and quality of sweet corn.

The volume of the butt logs and middle logs was compared to the real volume (control), which was calculated by aggregating the volume measurements at (0.5) meters using Newton's method. Measurements were taken from 50 trees of (Eucalyptus camaldulensis) planted in Al-Khabat area in Erbil governorate. The sampled trees presented diameter at breast height (DBH) ranged from 30.2 to 75.6 cm and total tree height range from 13 to 27 m. The result showed that Newton`s formula was superior to all other formulas for estimating butt log volume of eucalyptus tree species plantation and Smalian`s formula was less accurate than other formulas. On the other hand, the centroid method was superior to all other formulas for estimating the middle log volume of eucalyptus tree species in the district of khabat in Erbil province. Moreover, the Hossfeld formula was less accurate than other formulas.</p> Ameer Abdulazeez Abdulla, Mohammed Hadayat Obeyed Copyright (c) 2023 Ameer Abdulazeez Abdulla, Mohammed Hadayat Obeyed https://creativecommons.org/licenses/by-nc-sa/4.0 https://zancojournal.su.edu.krd/index.php/JPAS/article/view/350 Tue, 20 Dec 2022 00:00:00 +0000 Secondary data collected from Ifraz-2 Erbil for Drinking Water Quality Assessment https://zancojournal.su.edu.krd/index.php/JPAS/article/view/456 <p>The goal of the current study was to use the Water Quality Index (WQI) to evaluate the overall drinking water quality status in Erbil City, Kurdistan Region of Iraq, by estimating the quality of the Greater Zab River (raw water) and the water treatment plant WTP at Ifraz-2 on the Greater Zab River, a tributary of the Tigris River. Thirteen physicochemical parameters, including turbidity, pH, electrical conductivity, total dissolved solids, total hardness, calcium, magnesium, alkalinity, chloride, sodium, potassium, nitrate, and sulfate, were evaluated between 2010 and 2021 using the WQI. The calculated WQI for the Greater Zab River's raw water quality ranged from (140.532) to (422.455) and the calculated WQI for WTP (Ifraz-2) ranged from (44.197) to (69.118). Accordingly, the results of Greater Zab River water were categorized as "very poor," "poor," and "unsuitable" for drinking purposes during the studied period (2010–2021). Furthermore, the results of the computed WQI for WTP of (Ifraz-2) are classified as "Excellent" and "Good". According to WQI, the WTP of Ifraz-2 from the current study was of good quality and suitable for consumption by humans. As a result, the efficiency (E%) of the Ifraz-2 WTP was found to be more efficient in 2016 (89.49%) than in other years and suitable for drinking. Except for a few samples, the physicochemical quality of most drinking water samples during the current study was within WHO limits.</p> Lanja Omer Tahir Copyright (c) 2023 Lanja Omer Tahir https://creativecommons.org/licenses/by-nc-sa/4.0 https://zancojournal.su.edu.krd/index.php/JPAS/article/view/456 Tue, 20 Dec 2022 00:00:00 +0000 Influence of Bamboo Biochar and Gibberellic Acid on Vegetative and Flower Production of Tagetes erecta L. https://zancojournal.su.edu.krd/index.php/JPAS/article/view/336 <p> This research was carried out in open field Grdarasha, Agriculture College, Salahaddin University through March 18<sup>th</sup> to August 21<sup>th</sup> 2021 to study the effects of Bamboo biochar (0, 3, 6 and 9 ton.ha<sup>-1</sup>) as soil application and foliar spray GA<sub>3</sub> (0, 200, 400 ml.l<sup>-1</sup>) on (<em>Tagetes erecta </em>L.) vegetative growth and flowering.

The first step in road maintenance is to inspect the road surface and then accurately detect potholes. However, manually identifying them is costly and time-consuming. In this study, unmanned aerial vehicle (UAV) imagery was used to create orthophotos of the roads and, using deep learning methods, potholes were detected. The used deep learning method in this study is the "you only look once" (YOLO) algorithm. YOLO is one of the "deep learning-based approaches" to detecting objects and is a single-stage network which requires only one forward propagation across the neural network and focuses on the entire image. The fourth version of YOLO is YOLOV4, which has two different architectures (YOLOv4 and YOLOv4-tiny). Two roads were chosen as the study areas, and to generate the orthophotos of the roads, UAV was used to acquire images. To train both methods in the process of detecting potholes using deep learning, 5300 images were used, 90% used for training and 10% applied for testing. The two used architectures were trained for 6000 iterations. Both methods were evaluated based on the average loss, mean average precision (mAP), and training and testing time. The results showed that the (mAP) values for YOLOv4 and YOLOv4-tiny were 91. 2% and 85.7%, respectively. At the end of the 6000 iterations, the average loss for YOLOv4 is 0.30% and for YOLOv4-tiny is 0.34%. In the training process, YOLOv4 needs 29 seconds for each iteration, while YOLOv4-tiny requires only 8 seconds. In the test process, YOLOv4-tiny is faster at detecting potholes than YOLOv4. The approaches were tested on orthophotos created by processing UAV photos. When comparing the detection of both architectures with visual detection, the results showed that YOLOv4 was able to detect most of the potholes on roads, but YOLOv4-tiny detected a lower number of potholes.</p> Dana Mohammed Ali, Haval A.Sadeq Copyright (c) 2023 Dana Mohammed Ali, Haval A.Sadeq https://creativecommons.org/licenses/by-nc-sa/4.0 https://zancojournal.su.edu.krd/index.php/JPAS/article/view/247 Tue, 20 Dec 2022 00:00:00 +0000 The combined Application of Iron and Phosphate Solubilizing Bacteria to enhance Wheat (Triticum aestivum L.) growth and yield https://zancojournal.su.edu.krd/index.php/JPAS/article/view/351 <p>This study had the objective of evaluating the efficiency of prepared iron and phosphate biofertilizers in improving wheat growth and yield. To isolate bacteria that dissolve iron and phosphate, different soil samples were collected from the Erbil governorate, a total of eighteen iron solubilizing bacteria were selected on a modified agar medium and all isolates belonged to Pseudomonas fluorescence. Twenty-two isolates of phosphate solubilizing bacteria were recognized and referred to P. putida, P.fluorescens, and Bacillus megaterium using microscopical, cultural, physiological and molecular tests. According to iron and phosphate solubilizing efficiency test, the most efficient isolate of iron solubilizing bacteria (Pfl3) and P-solubilizin bacteria (Ppu2, Bm14) were selected for biofertilizers preparation&nbsp; Local and imported iron and phosphate biofertilizers were applied in pot experiment. Most biofertilizers were significantly increased yield components of wheat plants. Maximum shoot length, root length, tillers number,1000 seed weight, spike number and yield (99.60cm, 58.95cm, 22, 38.75g. 20, 5.52 ton/ha&nbsp; respectively) were recorded by incoculation with P. Flourence + P. putida +B. megatrium significantly higher than uninoculated control and treatments with imported biofertilizer. It can be concluded that local iron and phosphate solubilizing bacterial isolates can be used for Fe and P biofertilizers. &nbsp;&nbsp;</p> dedawan K.Rahman, Aras M Khudhur, Haifa S Yaseen Copyright (c) 2023 dedawan K.Rahman, Aras M Khudhur, Haifa S Yaseen https://creativecommons.org/licenses/by-nc-sa/4.0 https://zancojournal.su.edu.krd/index.php/JPAS/article/view/351 Tue, 20 Dec 2022 00:00:00 +0000 EVALUATION OF HEALTH RISK ASSESSMENT FOR CADMIUM, LEAD AND ZINK IN SOME COMMON CANNED FOODS IN ERBIL CITY MARKETS https://zancojournal.su.edu.krd/index.php/JPAS/article/view/407 <p>This study was conducted for assess health hazard and concentration of some heavy metals including, Zinc (Zn), Cadmium (Cd), and Lead (Pb) in some canned foods involved canned fish, canned cheese and canned tomato paste that selected randomly from various markets in Erbil city.

And monitoring the effectiveness of some of the most widely used biocides in our hospitals on these isolates and select the most effective one to be used in infection control of these hospitals. <strong>Methods:</strong> This study included 81 klebsiella spp. isolates were collected from different clinical specimen from different hospitals in Erbil City from 1August to 1 November 2021. Susceptibility against 50 isolates of <em>Klebsiella pneumoniae</em> was assessed for 10 antibiotics by the disc-agar method and ten biocides by the cup plate agar diffusion method. <strong>Results:</strong> From (81) isolates only 50 (%62) were <em>Klebsiella pneumonia</em>. There were 2(4%) isolates not biofilm producers and 48(96%) isolates as biofilm producers. Their antibiotic resistance profile showed all isolates (% 100) was resistance to Ampicillin, while (%74) isolates was showed susceptibility to Imipenim and Meropenim and (%57.1) to ciprofloxacin. Also, Statistical analysis showed that the higher and lower mean of biocide were Virkon and Alcohol- Base which were 51.54mm and 12.91mm respectively. <strong>Conclusion:</strong> Our observations imply that side by side bacteria increase the ability to resist against biocides. In addition, Virkon was the most effective biocide against <em>K. pneumoniae</em> isolates. We recommend pay attention to choose the best biocide to prevent the growth of pathogenic bacteria and control the infection in hospitals.</p> Halima Mohammed Saber, Payman Akram Hamasaeed Copyright (c) 2023 Halima Mohammed Saber, Payman Akram Hamasaeed https://creativecommons.org/licenses/by-nc-sa/4.0 https://zancojournal.su.edu.krd/index.php/JPAS/article/view/302 Tue, 20 Dec 2022 00:00:00 +0000 Optimisation of CAFE assay for the evaluation of ethanol preference in Drosophila melanogaster https://zancojournal.su.edu.krd/index.php/JPAS/article/view/278 <p><strong> </strong></p> <p> Alcohol is one of the most harmful psychoactive drugs which can cause various medical, physical, social, financial, and work-related problems.</p> <p>The fruit fly <em>Drosophila melanogaster</em> has been proposed to be a useful model to explore alcohol-induced behavioural, cellular and molecular mechanisms. The capillary feeder assay (CAFE) has been used to measure the development of preference for alcohol that is observable in <em>Drosophila</em> as well in mammals including humans.</p> <p>The aim of this study was to investigate and optimize the CAFE assay to validate further studies using this technique. The parameters that were investigated were: the ethanol concentration and length of exposure, both during pre-exposure and during the preference assay, and whether the sex of the flies affected the outcome. The results indicate that a minimum of two days of pre-exposure of 15% ethanol is required to induce preference for 15% vs 5% ethanol, while there was no significant difference in extending the preference assay beyond two hours and males and females flies behaved in similar manner. Overall these results further validate and better define the usefulness of the CAFE assay for the measurement of alcohol preference in <em>Drosophila</em> as a method to explore the mechanisms of preference which may apply also to higher organisms.</p> Jiyan Ali Omar Copyright (c) 2023 Jiyan Ali Omar https://creativecommons.org/licenses/by-nc-sa/4.0 https://zancojournal.su.edu.krd/index.php/JPAS/article/view/278 Tue, 20 Dec 2022 00:00:00 +0000 Epidemicity and Genotyping of Pediculus humanus capitis de Geer by Cytochrome Oxidase I gene among Syrian refugees dwelling some camps of Erbil, Kurdistan Region of Iraq https://zancojournal.su.edu.krd/index.php/JPAS/article/view/267 <p>The objectives of the current study are to determine risk factors associated with the rampancy and molecular genotyping of the head lice (Pediculus humanus capitis de Geer) infesting Syrian refugees in some temporary camps of Erbil, Kurdistan region of Iraq. To meet the requirements of the study, some primary schools of refugee camps were chosen to collect the relevant data in the afore-mentioned city. The V-Comb trap method was used to obtain specimens of head lice from 202 students of both gender who attend refugee camp schools regularly. The analyzed data revealed that the prevalence rates of pediculosis among 6-10 and 11-15-year-old students were 69% and 64% respectively. The highest infestation rate (79%) was recorded among female students, whilst the lowest outbreak rate (61%) was detected among male students. Regarding the impact of hair lengths on the prevalence of the insect, the highest rate of infection (81.53%) was recorded for medium hair whilst the lowest rate (41.17%) was determined for long hairs. Concerning the hair posture factor, the rates of infestation were 100%, 73% and 55% for spring, straight, and wavy hairs respectively in the 6-10-year-old group. Ultimately, Genomic DNA extraction were performed and Mitochondrion Cytochrome Oxidase I gene was used successfully for PCR amplification and sanger sequencing for genotyping then submission of our query sequences to the NCBI GenBank . </p> Hemdad H.

Using different copper salts and copper complexes as catalysts under benign to mild conditions at a temperature range (40-65˚C, under air) without the addition of any additives (base, oxidant, and ligands). The reactions were followed using a UV-Vis spectrophotometer and the absorbances were measured at maximum wavelengths for the biphenyl production of each five selected (1a-d). The observed rate constants (kobs) were calculated using a pseudo-first-order equation and unsubstituted 1a was selected for optimization processes. The experimental results showed good to excellent curve fit (R2=0.9967-0.9998) to the pseudo-first-order equation and origin software was used for this purpose. Among all copper catalysts, the observed rate constant (kobs) for cupric acetate (Cu(OAc)2)is much higher than others, (kobs=0.1605 min-1), while CuCl2.2H2O has a minimum observed rate constant, kobs=0.0216min-1. The two copper complexes [Cu(4-mba)2(tmeda)], and [Cu(3-mba)2(H2O)2(tmeda)] require a mild condition (85˚C) which is higher than other copper catalysts when 1a is used as reactant the value of kobs is (0.0176, 0.0343 min-1) respectively, while using p-tolylboronic acid (1b) as reactant the value of kobs is (0.0173, 0.0147 min-1) respectively.</p> Hawta K.

To find out the effect of menopause on sex hormone levels such as estrogen, testosterone, and progesterone in serum menopausal women and to elevate the relationship between these hormones and CVD. This case-control study included (224) participants (menopausal women with CVD and non-CVD) in the age range (of 40-69 years) who visited (The surgical specialty hospital cardiac center and Hawler teaching hospital). A self-administered questionnaire was used for data collection. Fasting serum metabolic parameters and hormones were measured which included (E2, TT, P, SHBG) and (Total Cholesterol, Triglycerides, HDL, LDL, and VLDL). Women with CVD represented 60.7%., who had previously been diagnosed by specializes in the cardiac center, and healthy menopausal women represented 39.3%. The mean value of E2 was significantly lower in menopausal women with CVD (20.066±1.773 Pg/ml vs 29.455±3.807 Pg/ml) along with serum progesterone level (0.234±0.0102 ng/ml vs 0.452±0.137 ng/ml) and SHBG level (31.705±1.085 nmol/L vs 37.191±1.804 nmol/L) compared to healthy menopausal women (for all, p&lt;0.05). On the other hand, a significantly elevated level of total testosterone (17.970±1.28 nmol/L vs 10.552±.99nmol/L) was observed in menopausal women with CVD compared with healthy women (p&lt;0.001). Multiple linear regression analysis showed the E2 negative correlation with LDL-C (p&lt;0.01), and TT negative correlation with HDL-C (P&lt;0.01). Low serum levels in terms of sex hormones, (E2, P, and SHBG) with high-level serum TT might be contributed to cardiovascular disease.</p> Halala H. Mohammed, Leweza B.

The synthetic pathway includes two steps, as described here: Initial step was synthesis of N-(4-(6-methylbenzothiazol-2-yl) phenyl)-1-(substituted phenyl)methanimine (1-7), via the reaction of 4-(6-methylbenzothiazol-2-yl)aniline with a variety of substituted benzaldehydes in absolute ethanol utilizing glacial acetic acid as catalyst. The next step was synthesis of tetrazole derivatives (8-14) by the reaction of the synthesized imines (1-7) with sodium azide in dry dioxane. Spectroscopic methods (FT-IR, <sup>1</sup>H-NMR and<sup> 13</sup>C-NMR) were used to determine the structures of the produced products. The synthesized compounds were tested for antibacterial activity against two types of bacteria<em> Staphylococcus aureus </em>(Gram +ve) and<em> Escherichia coli</em> (Gram -ve). The results showed good activities against both types of bacteria.</p> Bana S. Abdulrahman, Roshna B. Nadr Copyright (c) 2023 Bana S. Abdulrahman, Roshna B.
