Urinary tract infection is the presence of microorganisms mostly bacteria in the urinary tract, one of the reasons that increases the risk of infection is diabetes, which is the most common metabolic disorder that is increasing at an alarming rate all over the world, due to high blood sugar caused by weak immunity leading to This results in damage to neutrophil function and decreased antibacterial activity in urine and thus bacteriuria.The study included 118 samples (73 samples for diabetic patients and suffering from urinary tract infection, and 45 samples for UTI without diabetes), where the level of interleukin-6 was measured in these two groups and compared with the control group (20 samples), and the level of this immune cytokine was compared at Infection with different bacterial species.
The level of interleukin-6 was high in patients with urinary tract infection who did not suffer from diabetes, which reached (24.1 ± 8.75) ng/ml compared to the control samples whose level was (0.763 ± 4.18) ng/ml and with a significant difference (0.01>p). . There is a significant increase for IL-6 in patients with urinary tract infection without diabetes (2.58±9.77) compared to the control samples whose level reached (0.551±3.79) at a significant level (P>0.01).
The highest level was when infected with E.coli and its level was (3.92 ± 17.51) ng/ml in normal UTI patients and (2.571 ± 13.43) ng/ml in diabetic patients.

The association between obesity and type 2 diabetes may be partially mediated by altered adipose tissue secretion of adipokines. Adiponectin is an adipokines with anti-inflammatory and insulin-sensitive properties. It is a regulated low secretion in obesity, the concentrations of adiponectin and calcium in the blood serum of obese patients and type 2 diabetes will be estimated in Salah al-Din Province: Iraq, where the study included (90) samples (60) for patients with diabetes - type II and (30) from healthy subjects. The ages of the affected and healthy people ranged between 35-75 years. The results showed a significant increase at the level of probability (P≤0.01) in the level of adiponectin and calcium concentrations in patients with type 2 diabetes compared to healthy subjects, and through the results we obtained, adiponectin may play an important role in prevention of type 2 diabetes.

This study investigates reservoir quality for the Middle–Late Eocene Pila Spi Formation in Shaqlawa (Sarkand) and Gulley Keer (Shekhan) areas in Kurdistan Region of Iraq. Lithologically, the Pila Spi Formation in the studied sections is composed of limestone, dolomite, dolomitic limestone, chalky limestone, and marl. The thickness of the formation is about 102m and 200m in Sarkand and Gully Keer sections respectively. In order to evaluate the reservoir characterization of the studied formation, different techniques such as a microscopic study and core plug analysis were used. The Pila Spi Formation is characterized by several pore's types namely; vugs, moldics, channels, interparticles, fractures, boring, fenestral, and intragranulars. Several diagenetic processes were also recognized such as dolomitization, pressure solution, stylolization and dissolution. Based on the petrographic study, the lower part of the formation in Sarkand section has a porosity average of 8%, while it has an average of 21% and 17% in middle and upper parts. In Gulley Keer section, the porosity values of the formation are about 9%, 17, and 19%, in the lower, middle and upper part, respectively. The Scanning Electron Microscope (SEM) study shows almost the same porosity values, and the pore's sizes are between micropore to mesopore for the studied sections. Furthermore, the results of the core plugs analysis are roughly in agreement with optical assessments since the measured porosity values from Sarkand section are 8%, 18.5%, and 18% for lower, middle and upper parts, respectively. The porosity values of Gulley Keer section for lower, middle and upper parts of the studied section are 2.5%, 17.25%, and 22.5%, respectively. Consequently, the results revealed that the Pila Spi Formation has a good porosity except the lower part. In regards with permeability, the measured values of permeability displayed an avenge of 0.109md and 0.6698md for Sarkand and Gulley Keer respectively in which suggested fair to good permeability.

The Govanda Formation was deposited during the Early-Middle Miocene Epoch in the intermountain areas between Zagros Suture and Imbricate zones. The Paleoecology and depositional environment of the Govanda Formation has been studied in detail in Mergasor and Penjwen districts for the first time. The formation in these two sections from bottom to top is comprised of thick bedded, oyster and chert bearing conglomerate, pebbly sandstone, red-brown shale and siltstone, fossiliferous limestone and detrital limestone. The formation in Mergasor, Beshkariya Village is 85 m thick and in Penjwen, Gole Village is 60 m thick. The study is based on the detailed microscopic analysis on the benthic and planktonic foraminifera with miscellaneous fossils that exists in the carbonate rocks of the Govanda Formation. Larger and smaller benthic foraminifera include the following genera: Operculina sp., Borelis melo sp., Austrotrilina sp., Peneroplis sp., Meanderopsina sp., Miogypsinoids and Miogypsina sp., Archaias sp., Amphistegina sp., Textularia sp., Lepidocyclina sp., Miliolids, Quenquiloculina sp., Pyrgo sp., Spiroloculina sp., Triloculina sp., Ammonia sp., Elphidium sp., Dendritina sp. and Rotalia venoti dominated the limestones of the Govanda Formation. Planktonic foraminifers are mostly includes the following genera: Globigerinoids sp., Globigerina sp., Globorotalia sp. and Orbulina sp. Moreover, miscellaneous fossils include corals, coralline red algae, echinoderms, bivalves, ostracods, bryozoans, brachiopods and serpulid worms (Ditrupa sp.). The paleoecological condition of the formation was interpreted as follow; the temperature of the Govanda basin ranges between 15-30 °C, nutrient level is between eutrophic to mesotrophic, salinity ranged between normal saline to hypersaline water, light intensity ranging from euphotic to mesophotic and less oligophotic zones, the water depths ranged between 0-120 m, the clastic influx was high in the basin, differences in size and shape within foraminifers of the Govanda Formation indicate various depositional environments and ecological conditions, the water energy was moderate. The environment of deposition is interpreted as being ramp environment. Depending on the different microfauna that exist in the formation, four main zones are distinguished in the ramp model of the Govanda Formation as follows; proximal inner ramp setting which includes open lagoon, distal inner ramp setting which includes back-reef environment, proximal middle ramp setting which includes reef and fore-reef environments, distal middle ramp/ proximal outer ramp setting, which includes open marine environment.

The stratigraphy and mineralogy of Balambo Formation (Aptian - Cenomanian) in exposed surface section near Chomabrok village in the Imbrication zone, northeastern Iraq is studied. The Formation is 450 meters thick and consists of thin to medium to thick bedded yellowish-brown, and black to dark gray limestones, marly limestones, with thin- medium bedded, grayish - black marl and shale, with thin bands of black cherts and abundant nodules and lenses. From the field observations and petrographic studies, the formation mainly made from two main lithofacies types; marly limestone-marl lithofacies and cherty limestone lithofacies. The petrographic study of carbonate rocks deepened on 79 thin sections and demonstrated that the carbonates of Balambo Formation composed of micrite ground mass with abundant skeletal grains; planktonic and some benthic foraminifera, radiolaria, calcisphere, ostracods, pelecypods, larva-ammonoids, small-brachiopods, sponge spicules, echinoid spines, and bioclasts. Non-skeletal grains include peloids only. Using extraction method and according to an assessment of foraminiferal assemblages and based on the defined planktonic foraminifera the assigned age of Balambo Formation in the studied section is Aptian to Cenomanian as upper Balambo age. The results of X-ray diffraction (XRD) analysis for bulk mineralogy of selected shale and marl samples suggested the presence of phyllosilicate with abundant calcite, common quartz, and moderate Fluorapatite with minor dolomite content. Illite is the dominant clay mineral in the Balambo Formation and indicates a hot, arid climate during most

Thermal plasma spraying method was used for coating the pre-prepared surfaces of turbine blades. Nickel (Ni) was used as a base material with a fixed percentage of alumina (5%Al2O3), and (5,10,15,20,25%) of Boron carbide (B4C) as reinforcement material. Cermet powders were mixed for one hour, then the coating bases of steel type (316L) were prepared and roughened using sandblasting to increase the adhesion strength between the coated materials and the base. The bonding material represented by (Ni-22% Cr-10%Al-1%Y) was sprayed with a thickness of (150µm), and then the base and reinforcement material were sprayed with a thickness of (350-400 µm). Thus, the final thickness of the prepared samples was (550-500 µm). After that, the samples were sintered at 900°C for two hours. The hardness test was applied to the samples, indicating the best hardness after sintering at (25%) reinforcement ratio of 590Hv. As for porosity, its lowest value was obtained at 7%, while the best value of adhesion strength was obtained after sintering at (25%) of B4C. However, the results of the scanning electron microscope (SEM) showed the weakness and the presence of pores in the coating layers at the low percentage of reinforcement. While the mechanical and physical properties were improved with the increase

ABSTRACT
Polycrystalline thin films were prepared from CdO nanoparticles in the chemical Bath deposition (CBD) with different molar concentrations at (0.01, 0.03, 0.05, 0.07) M.
In order to obtain the best results, the structural and optical properties of CdO films were studied under the influence of increasing molar concentration, the results of the absorbance measurements there showed a change in the absorbance spectrum of the (CdO) films upon the increase in the molar concentration in the deposition, The value of the absorbance is within the limits of short wavelengths and where the absorbance increases at the wavelength (λ≤550 nm), and we note that it increases with the decrease in the wavelength and that the increase in the molar concentration in the deposition leads to an increase in thickness where the greater the absorbance increases the thickness. All samples of the prepared films were examined using scanning electron microscopy (SEM) at 2,000x magnification in order to identify the nature of the surface of the prepared films and to note the change in particle size with increasing molar concentration in the deposition. Experimental results showed that the grain size increases its crystal growth with increasing molar concentration, and this was shown by X-ray, AFM measurements.

Online social media (OSM) generates a massive amount of data about human behavior based on their interactions. People express their opinions, comments and share information about variety of topics of their daily life through OSM. The majority of the comments are divided into three categories: Positive, negative, and natural. Regarding the negative comments, the OSM platform facilitates abnormal actions, such as unsolicited messages, misinformation, rumors, the dissemination of fake news and propaganda, as well as the dissemination of malicious links. Therefore, one of the most significant data analytic activities for identifying normal and deviant individuals on social networks is abnormality detection. This paper proposes a hybrid model based on three famous deep learning approaches to discover the behavioral abnormalities, and negative comments in the OSM platforms. The selected benchmark for our research is the airline sentiment in a Twitter dataset. In the proposed method, the dataset is fed to the LSTM network; next, the output of LSTM feeds the CNN network. CNN combines features and generates various feature maps. In the next step, we reduce and select the most important features. Finally, the selected features are given to ANN to classify the data. The proposed method (LSTM + CNN + ANN) is compared with various classical machine-learning (ML) techniques. The experimental results show that the proposed method enhances the accuracy and precision on average by %8.6 and %8.4, respectively in compared to the classical ML techniques
