Background: Hashimoto's thyroiditis has been found to coexist with differentiated thyroid cancer in surgical specimens, but an association between the two conditions has been discounted by the medical literature. So, we performed this research to determine any potential relationship between Hashimoto's thyroiditis and the risk of developing differentiated thyroid cancer in clinical status. we assessed the related clinical factors linking these conditions, especially serum thyroid-stimulating hormone concentration, family history of thyroid disease, gender& young age group. Aim of study: to determine that hashimoto’s thyroiditis increases risk for differentiated thyroid carcinoma. Patients and method: This study is a Cross-sectional study carried out in surgical ward of Baghdad teaching hospital, where 82 patients followed up for one year from 1/10/2017 to 1/10/2018. Clinical history and examination with thyroid function tests, ultrasound and FNAC done for them pre operatively, post-operatively all thyroid specimen sent for histopathological study. Results: Differentiated thyroid cancer with Hashimoto's thyroiditis patients: (84.6%) had papillary thyroid cancer with Mean age of patients is 37.3±3.3 and Female gender represents 92.3% of differentiated thyroid cancer with Hashimoto's thyroiditis patients. About 53.8%of differentiated thyroid cancer with Hashimoto's thyroiditis patients had high thyroid-stimulating hormone at presentation. About 61.5% of differentiated thyroid cancer with Hashimoto's thyroiditis patients had positive family history of thyroid disease. Most our patients had multinodular goiter 80.5%, only 19.5% had single nodule, in Differentiated thyroid cancer with Hashimoto's thyroiditis patients (papillary thyroid cancer: 81.8% multinodular goiter and18.2% Single nodule, while all Follicular Thyroid Cancer patients had multinodular goiter).Fine needle aspiration biopsy in diagnosis of Hashimoto's thyroiditis pre-operation had Sensitivity 61% & specificity98%.

Because the Coronavirus epidemic spread in Iraq, the COVID-19 epidemic of people quarantined due to infection is our application in this work. The numerical simulation methods used in this research are more suitable than other analytical and numerical methods because they solve random systems. Since the Covid-19 epidemic system has random variables coefficients, these methods are used. Suitable numerical simulation methods have been applied to solve the COVID-19 epidemic model in Iraq. The analytical results of the Variation iteration method (VIM) are executed to compare the results. One numerical method which is the Finite difference method (FD) has been used to solve the Coronavirus model and for comparison purposes. The numerical simulat

In this paper , the CO2 laser receiver system is designed and studied, with wavelength laser 10.6 ?m in room temperature , and to evaluate the performance and discussion it via the package of optical design (ZEMAX), from its output the Spot Diagram is measured through RMS ,and from the Ray fan plot , the aberrations is found which is the normal error for the best focus named (under corrected ) , the other output was the Geometric Encircled Energy in the spot diagram . and found that the radius of spot diagram at 80% (R80%) from the total energy ,and focal shift .The designed system have high efficiency and low cost .
Passive optical network (PON) is a point to multipoint, bidirectional, high rate optical network for data communication. Different standards of PONs are being implemented, first of all PON was ATM PON (APON) which evolved in Broadband PON (BPON). The two major types are Ethernet PON (EPON) and Gigabit passive optical network (GPON). PON with these different standards is called xPON. To have an efficient performance for the last two standards of PON, some important issues will considered. In our work we will integrate a network with different queuing models such M/M/1 and M/M/m model. After analyzing IPACT as a DBA scheme for this integrated network, we modulate cycle time, traffic load, throughput, utilization and overall delay

Ziziphora persica Bunge is recorded as a new Study in Iraq. This species has been collected from Jabal Sinjar in Nineveh province in the north western part of Iraq. The morphological characters, habitat and geographical distribution of the species with a key to Ziziphora L. species in Iraq have been provided.
