Studying the Behavior of Asphalt Stabilized Gepseous Soil for Earth Embankment Model
The study presents the test results of stabilizing gypseous soil embankment obtained from
Al- Faluja university Campus at Al-Ramady province. The laboratory investigation was divided
into three phases, The physical and chemical properties, the optimum liquid asphalt (emulsion)
requirements (which are manufactured in Iraq) were determined by using one dimensional
unconfined compression strength test.in the first phase , The optimum fluid content was 11%
(6% of emulsion with 5% water content).. At phase two, the effect of Aeration technique was
investigated using both direct shear and permeability test. At phase three for the case of static
load , the pure soil embankment model under dry test condition was investigated, The testing
program included the determination of the unconfined compressive strength, direct shear
strength, constant head permeability test, and one dimensional consolidation test for pure and
asphalt stabilized gypseous soil. Testing was carried out in dry and absorbed conditions, the
maximum pressure that can be supported before failure (ultimate sustained pressure) is 0.76
MPa with vertical settlement (0.21 mm) . However, For the pure soil embankment model under
absorbed condition it was found that the maximum pressure before failure (ultimate sustained
pressure) is 0.3 MPa with vertical settlement (12 mm), Which reflects the reduction in bearing
capacity by (61%). Compression was made for absorbed stabilized soil and un-absorbed soil
tested under hydraulic conductivity test for seven days, the results showed that a very low
margin deffeneces in maximum pressure resistance and settlement were obtained (4.38 MPa ,
0.11mm ) and (4.11MPa , 0.12mm)

Radiation beam scanning for leaky wave antenna by using slots
This paper provides an insight of a new, microstrip leaky wave antenna. It holds the ability to continue steer its beam at a swapping frequency. This is done with acceptable impedance matching while scanning and very little gain variation. Investigation is carried out on LWAs’ control radiation pattern in steps at a band frequency via vertical and horizontal slots. The enhancement is realized by etching horizontal and vertical slots on the radiation element. This study also presents a novel half-width microstrip leaky wave antenna (LWA). The antenna is made up of the following basic structures group’s vertical and horizontal slots. The reactance profile at the microstrip’s free edge and thus the main beam direction is changed once the control-cell states are changed. The radiation pattern direction changes by sweeping the operating frequency between 4 GHz to 6 GHz.The main beam may be directed by the antenna between 15o and 55o. C band achieved the measured peak gain of the antenna of 10 dBi at 4.3 GHz beam scanning range
Review on fixed-frequency beam steering for leaky wave antenna
This paper aims to survey the efforts of researchers in response to the novel and effective technology of control radiation pattern at a fixed frequency for leaky wave antenna (LWA), map the research landscape from the literature onto coherent taxonomy and determine the basic properties of this potential field. In addition, this paper investigates the motivation behind using beam steering in LWA and the open challenges that impede the utility of this antenna design. This paper offers valuable recommendations to improve beam steering in LWA. The review revealed the development and improvement of several techniques of beam scanning LWA.

A new model for iris data set classification based on linear support vector machine parameter's optimization
Data mining is known as the process of detection concerning patterns from essential amounts of data. As a process of knowledge discovery. Classification is a data analysis that extracts a model which describes an important data classes. One of the outstanding classifications methods in data mining is support vector machine classification (SVM). It is capable of envisaging results and mostly effective than other classification methods. The SVM is a one technique of machine learning techniques that is well known technique, learning with supervised and have been applied perfectly to a vary problems of: regression, classification, and clustering in diverse domains such as gene expression, web text mining. In this study, we proposed a newly mode for classifying iris data set using SVM classifier and genetic algorithm to optimize c and gamma parameters of linear SVM, in addition principle components analysis (PCA) algorithm was use for features reduction
Histophysiology study of interleukin-4 in thyroid cancer patients
Introduction.Interleukins have promising prospects in the clinical treatment of cancer. Interleukin-4 (IL-4) is an anti-inflammatory cytokine with an immunosuppressive effect on antitumor activity by immune cells, but the mechanical action of IL-4 in thyroid cancer is unknown. Aim: to investigate the effect of IL-4 expression in thyroid cancer patients. Furthermore, to clarify the association between obesity and thyroid cancer.
Material and methods.The present study was conducted on 115 subjects with thyroid nodules (36 with thyroid cancer and 79 with benign lesions) in Basrah, Iraq, from November 2019 to April 2022. To conduct a histophysiology study of IL-4.
Results.There was a significant difference in serum IL-4 between the thyroid cancer and control subjects. A higher level of serum IL-4 was observed in the Hashimoto thyroiditis group. There was no significant difference in body mass index (BMI) between thyroid cancer and control subjects. The expression of tissue IL-4 in thyroid cancer patients was strong in 8 (22.22%) slides, moderate in 7 slides (19.44%), weak in 8 slides (22.22%), and negative in 13 slides (36.11%), while in the control group, it was strong in 7 (30.44%) slides, moderate in 8 slides (34.79%), weak in 5 slides (21.74%) and negative in 3 slides (13.03%).
Conclusions.These findings indicate that serum levels of IL-4 may help diagnose thyroid cancer and identify patients with active disease who deserve closer medical attention. Furthermore, the secretion of IL-4 was systematic and not localized in thyroid cancer tissues. Obesity was not associated with a prevalence of thyroid cancer

Blood parameters, symptoms at presentation and adverse in-hospital outcomes of COVID-19 pneumonia in patients with hypertension
Background: We aimed to explore the association of clinical symptoms of COVID-19 pneumonia, blood parameters on admission, and anti-hypertensive drugs with in-hospital outcomes, including length of hospital and intensive care unit (ICU) stay, receiving mechanical ventilation, degree of lung injury, and in-hospital death among patients with hypertension.
Material and methods: This retrospective study conducted in patients with newly diagnosed COVID-19 pneumonia from August 20, 2020 to September 25, 2020.
Results: A total of 182 patients with COVID-19 pneumonia were included in the present study. The patients were categorized into those with hypertension (n = 82) or without hypertension (n = 100). Patients on angiotensin receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs) showed no significant increase in the risk for all in-hospital outcomes. Old age [0.6 (0.5–2) p < 0.00], fever [0.3 (0.2–1.8), p < 0.00] and low lymphocytes percentage [0.3 (0.2–1.2), p < 0.00] were associated with increased risk for extensive lung injury. Old age [0.4 (0.1 = 0.7) p < 0.01], high neutrophil count [0.3 (0.2–2), p = 0.02] and low lymphocyte percentage [0.3 (0.1–0.7), p = 0.01] were associated with prolonged hospital stay while low lymphocytes percentage [0.7 (0.6–0.9), p < 0.00], old age [1.2 (1–1.4), p = 0.01] and fatigue [2 (1–4), p = 0.04] showed significant association with prolonged length of ICU stay. Low lymphocytes percentage [0.7 (0.6–1), p < 0.00], old age [1.1 (1–1.2), p = 0.01] and fatigue [2 (1.7–4), p = 0.02] were associated with increased risk for receiving mechanical ventilation. Risk for in-hospital death was associated with increased neutrophil percentage [1.2 (1–1.5), p = 0.01] and old age [1.1 (1–1.2), p = 0.03].
Conclusions: ARBs and ACEIs showed no significant association with adverse in-hospital outcomes. Old age, low lymphocytes percentage and high neutrophils percentage on admission were independent predictors for increased risk of in-hospital mortality and morbidity among COVID-19 pneumonia patients with hypertension
