Statistical Process Control (SPC) is approaching that uses statistical techniques to monitor the process. The methods of quality control are widely used in controlling any strategy—the widely used control charts. A traditional variable control chart includes three lines: the Centre Line (CL), the Upper Control Limit (UCL), and the Lower Control Limit (LCL), all of which are represented by numeric values—represented by numeric values. A control chart illustrates the centerline of the average value of the quality feature under investigation. Depending on numeric observation values, a process is either "in control" or "out of control." Considering the current, there are no questions regarding the observations and their values during the production process. However, when these observations include human judgments, assessments, and choices, a continuous random variable (xi) of a manufacturing process should be made up of the variable. The MEWMA and Mahalanobis distance control chart techniques are used when more than one variable is involved. This paper aims to compare the MEWMA and Mahalanobis distance chart for three compounds for water drinking production in the ALA -Factory in the Sulaimani-Iraq region. So, linguistic terms can be used instead of the exact value of the continuous random variable. Today, quality control has become one of the most essential techniques for studying all variables to control production or consumption decision factors. Quality control's primary aim is to guarantee that the goods, services, or processes delivered satisfy particular standards and are reliable and satisfactory. The factor's direct approach is based on the product's quality.

A factorial experiment with complete randomized design carried out in Erbil governorate, Iraq on two varieties of pears (Pyrus communis L.) spadona and compote cv. to investigate the effects of ethylene and temperature treatments on fruits ripening. The experiment includes four treatments; the control (cold storage at 0±1 C° and 85-90 relative humidity), the second was putting the fruits in ambient temperature with exposure to ethylene gas (300 mg/l) for 24 hours, third and fourth treatments were putting the fruits in the ripening cabinet at 20 C° either for 8 days, or 12 days. Results indicate that compote variety was differing significantly in decreasing weight loss and fruits firmness and increasing fruits peel pigments content and peroxidase enzyme activity compared to spadona variety. Slower ripening process was gained from cold storage treatment where the fruits remain non-ripened compared to other treatments, whereas ripening fruits at 20C° for 12 days fastened the ripening process by giving highest TSS, and lowest fruits firmness, in addition to percent of weight loss. For the condition of northern Iraq, the best treatment for ripening pear fruits is treating with ethylene gas or ripening the fruits at 20C° for 8 days.

The influence of high irradiance, drought stress and their cross-talk were explored in tobacco plants (Nicotiana tobaccum) grown under low light (250 μmol m-2 s-1) irradiance (LL) and high (1600 μmol m-2 s-1) irradiance (HL) then exposed to water deficient condition for 7 or 14 days. The detached leaves of HL-treated plants showed less water loss compared to LL plants. The HL-treated and 7 days drought-stressed plants had higher fresh and dry weights, as well as water content than the LL and drought-stressed leaves. The survival rate in 21 days drought-stressed plants after 3 days of re-watering was 50% in HL-grown and 0% in LL-grown plants. A transcriptome profiling analysis of the tobacco responses to light intensity highlights the increased abundance of a large group of drought-related transcripts including DROUGHT-RESPONSIVE ELEMENT BINDING FACTORS (DREBs), C-REPEAT/DROUGHT-RESPONSIVE BINDING FACTOR 1 (CBF1), GLYCINE-RICH RNA BINDING PROTEINS (GRPs), WRKY33 and MYCs transcription factors, as well as zeaxanthin epoxidase, which play as a regulator of plant responses to water deficient condition. These findings identify light-dependent changes in the cell redox state that limit water loss and enhance plant responses to drought stress.

Abstract Background: In this study, we have used the middle hepatic vein with the right lobe, and we studied the venous outflow dynamics immediately after transplant retrospectively meanwhile we studied the impact of the graft function on donor functionality and overall donor safety. Method: Between October 2017 to October 2020, we performed 40 adult to adult live donor liver transplants at Zheen International Hospital (Erbil, Kurdistan Region). Postoperative Doppler ultrasound was performed for recipients and donors immediately after surgery and then daily until discharge. Results: The donor age (28.5 ± 6.9) year, male/ female 19/ 21, intensive care unit stay (1.2 ± 0.43), floor stay (5.2 ± 1.4) days, their portal vein velocity (43.5 ± 18.4 ml/sec), hepatic artery resistive index (0.6 ± 0.09) and triphasic/ continuous venous outflow 30/10, their postoperative day one and at the discharge total serum bilirubin were (2.8 ± 1.8) and (2 ± 1.4), their postoperative day one and at the discharge international normalization ratio were (1.7 ± 0.5) and (1.2 ± 0.2) respectively. The recipient age (48.5 ± 11.3), male/female 27/13, intensive care unit stay (4.75 ± 3.9), floor stay (7.7 ± 3.7) days, portal vein velocity (63.96 ± 24.65 ml/sec), hepatic artery peak systolic velocity (74.76 ± 32.85) hepatic artery resistive index (0.7 ± 0.15), and triphasic/continuous venous outflow 27/13. Conclusions: Middle hepatic vein incorporation in live donor liver graft is safe with a favorable outcome for recipient and donor, doppler US is one the important tool for evaluation and follow up of donor and recipient for detection of vascular complications and assessment of venous outflow and graft function. In addition, early discharge of the donor is a reasonable option.

This is a multi-center retrospective study of patients underwent low anterior resection for rectal cancer. Ileostomy had been done to protect low lying Colo-rectal anastomosis, closure of ileostomy had been delayed in some patients due to patient own will, surgical complications (anastomotic leak) or coarse of chemotherapy. This study aimed to find the effect of temporary ileostomy on post-operative bowel defunction which is called Low anterior resection syndrome (LARS), and include; urgency, difficulty in emptying of bowel, and incontinence for feces and flatus. A total of 50 patients included in this study, the age ranges from the 19 to 80 years old with a mean age of 51.96 years. The total number of males was (33, %66). Majority of patients were overweight (21, 42%). The distance of tumors from the anal verge were less than 10 cm in (31,62%). The mean duration of fecal diversion was 7.17 months. Loop ileostomy were closed before six months in (27,54%). The mean duration of diversion of patients developed no LARS was 6.87 months which is shorter than those of developed LARS (7.31). Lower BMI patients are more prone to develop LARS, while Obese patients are more susceptible to develop major LARS. Nineteen cases developed LARS among those patient’s ileostomy closed before six months, and 15 cases developed LARS in those ileostomies closed after six months.

The expansion of urbanization and the lack of open spaces in cities, urban green spaces have become very important, especially in recent decades. Among urban green spaces, parks are important because they have leisure and recreational functions, and the favorable physical and mental effects on humans have been proven today. Depreciation of materials, park equipment, destruction of vegetation and lifestyle changes over time have changed the needs and desires of the people and caused the old parks do not meet the needs of citizens. Today, improving parks is a new approach that makes parks matches the demands human beings have evolved over time with the advancement of technology. Shadi Park in Iraq is one of the regional urban parks; the lack of its design, as well as the wear and tear of some uses, lack of optimal lighting system and various uses by different age groups reduces the number of visits. In this research, based on field perceptions of the park and public opinion polls, prioritization and solutions to strengthen the presence of people has been pointed out. The results of the questionnaire indicate the priority of people's demands, the most important of which include: building a sports venue for women, proper service of restaurants and cafes during the day and night, the presence of swimming pools and fountains in the park, parking at the entrances, space allocation to hold cultural and artistic festivals.

A laboratory study for adsorption of potassium (K) determination was conducted on six soils located in Sharazur plain from the Kurdistan Region of Iraq in 2021 using the batch technique method. Potassium (K) adsorption isotherms were achieved by equilibrating 5.0 g of soil samples with eight grades of K (0 to 300 mg L-1) as KCl in 50 ml of 0.01M CaCl2 solution. To match the data of adsorption, Freundlich, Langmuir, and Temkin adsorption isotherms were used. The results show that the amount of adsorbed K ranged between (45.78 to 52.49) % added K. The Freundlich model fit the equilibrium K adsorption data better for the Serwan location of soil (silty loam), as demonstrated by a greater coefficient of determination (R2 =0.90). The value of heterogeneity factor 1/n for the Freundlich model ranged from (0.34 to 0.47) kg mg-1, which was less than one. The sorption processes for all of the studied soils were normal adsorption. The constant of the Langmuir isotherm (KL) aligned from (0.107 to o.425) L mg-1. Smaller KL values mean that more adsorbed K would be transformed to a non-exchangeable form, either through the creation of crystalline K or through ion occultation. The RL values indicate the type of isotherm, the values of RL> 1 that means the adsorption nature to be unfavorable. The Temkin equilibrium binding constant (AT) was high for all studied soils except the soils of Bestan Sur and Grdigo locations, the high value of AT indicates high binding energy. The Temkin constant (bT) ranged from (10.46 to 13.47) J mole-1 that was related to the nature of the adsorption energy, a positive value indicates that the adsorption process is exothermic.

Recent power distribution networks comprise abundant sensitive loads, which extremely impact the power quality of source in electrical power networks. Voltage dip, voltage rise, imbalanced voltage, line notching and distortion of harmonics are problems of power quality frequently take place. Pre-disturbance voltage compensation strategy and phase-locked-loop (PLL) based dq- space vector control are presented to improve a Dynamic Voltage Restorer (DVR), which restore the magnitude of voltage disturbance and displacement of phase angle to prior of voltage disturbance. 3-phase Multilevel strategy of Space Vector Pulse Width Modulation (MSVPWM) based- Multilevel Diode Clamped Converter (MDCC) is proposed as switching pulse signals employed low frequency, which creates high levels of voltage and fewer harmonics in the output waveform in comparison to 2-level SVPWM based- DVR. 3-level SVPWM based- DVR under balanced and imbalanced distortion voltage disturbances included sags and swells injected appreciated quantities of voltage, thereby attained ideal sinusoidal waveform with lower Total Harmonic Distortion THD% compared to 2-level SVPWM based- DVR. Furthermore, real and imaginary powers balanced effectively at sensitive load during various distortion voltage disturbance conditions via presented work. The proposed simulation model of multi-level SVPWM based- DVR is implemented by dedicating the software system of MATLAB/SIMULINK. The results of simulation exhibit the effectiveness and efficiency of the presented work under different distortion voltage disturbance conditions.

Diabetes mellitus is one of the most common chronic health condition worldwide and the most common endocrine disease in children and adolescences. The aim of this study is to find out the risk factors, which lead to pathogenesis of type 1 diabetes mellitus among children and adolescent in diabetes health center Suleimani city. A descriptive cross sectional study was conducted at a special center for Type 1 Diabetes Miletus A questionnaire was developed and administered to a convenience sample of (170 ) mothers or fathers. Descriptive statistics data (frequency, percentage, mean and stander deviation) and also Factorial analysis (principal component analysis) was used in order to identify the effective factors affecting diabetes in children and Adolescents. The finding show that, 39.4 % of samples were aged between (9-13) years old, which stated as the highest rate among all age groups, while the minority of age was between (1-4) years old, which was equal to 8.2% of the total and the (Mean ±S.D) was equal to 10.44±4.04 respectively. The majority of age at diagnosis was between (5-8) years old, which is 35.3% and their food habit was normal diet, which is 73.5%, while the Sugar diet and Fatty diet were 25.9% and 0.6%y respectively. Most of the participants, 19.4% of family history was Type 2 diabetes, which was the first rank of the family history and majority of them were Kurdish in nationality. Age at diagnosis and mode of delivery considered as the first factor affect the type 1 diabetics mellitus. The second most common factor effect on diabetes disease in children and adolescents are maternal habit and maternal disease followed by Gestational age at birth and Neonatal disease, then food habits, Neonatal weight was estimated as the fourth component factors affecting Type 1 diabetes mellitus. Residency and Family history of autoimmune disease were ranked in the fifth line of factor, finally the weakest factor is nationality by total variance of 8.552%. The first years of life is play an important role in triggering and the development of type 1 diabetes mellitus among children and adolescent , also maternal diseases ( gestational diabetes, pre-eclampsia and perinatal infection during pregnancy), healthy diet during pregnancy and education programs are recommended

Liver mineral concentrations of 232 samples from slaughtered animals, including lamb, yearling, sheep, and cattle, checkin, and fish were detrmined, using X-ray fluorescence spectrometer, to provide data regarding to the liver mineral concentrations (mg/kg dry weight). The mean liver Zn and Co liver conentrations of lambs (286, 1.9), yearling (233, 1.7), sheep (254, 1.8), and cattle (276, 1.8) in majority samples were adequate, while liver Pb concentrations of mentioned animals (45.3, 48.1, 46.4, 39.6) mg/kg respectively were high and exceeded toxic levels. In checkin, the mean liver Cu, Zn, and Co were also adequate, with the mean values of (26.4), (298.8), and (1.8) mg/kg respectively. Though, the mean liver Fe concentration (2257.0 mg/kg) was high, and liver Pb concentration (6.2 mg/kg) was reched toxic level. In fish, for majority liver samples, the mean concentration of Cu (191.8), Fe (6800.0), Zn (202.8), Co (3.3), Pb (8.6), and Ni (6.3) were high and toxic. In conclusion, liver Pb (and Ni only in fish) concentration in all studied animals for the majority of examined sample were higher than normal and toxic. Wherese, other studied minerals in majority of liver samples were adequate. Therefore, it can be concluded that there are problems on animal and human health (due to high concentration of Pb and Ni) would be raised at present from the consumption of ovine, bovine, checkin, and fish slaughtered from the city of Erbil.
