In this work, two cone-inverted cylindrical and cross-hybrid dielectric resonator antennas are stacked and excited by the coaxial probe method with an operating standard resonant frequency of 5.438 GHz. A drawback of these standard Dielectric Resonator Antennas (DRAs) is their narrow bandwidth. For good antenna performance, a stacked DR geometry and a thick dielectric substrate having a low dielectric constant are desired since this provides large bandwidth, better radiation power, reduces conductor loss and nonappearance of surface waves. Many approaches, such as changing the shape of the dielectric resonator, have been used to enhance bandwidth. Using DRA, having the lowest dielectric constant, increases the bandwidth and the electroma

A theoretical study to design a conformal microstrip antennas was introduced in this work. Conformal microstrip antennas define antennas which can be conformed to a certain shape or to any curved surface. It is used in high-speed trains, aircraft, defense and navigation systems, landing gear and various communications systems, as well as in body wearable. Conformal antennas have some advantages such as a wider-angle coverage compared to flat antennas and low radar cross-sectional (RCS) and they are suitable for using in Radome. The main disadvantage of these antennas is the narrow bandwidth. The FDTD method is extremely useful in simulating complicated structures because it allows for direct integration of Maxwell's equations depending o

 Is the subject of the financial structure of the most important topics for which she received the interests of scientific research in the field of financial management , as it emerged several theories about choosing a financial structure appropriate for the facility and behavior change funding them , and in spite of that there is no agreement on a specific theory answer various questions in this regard , and a special issue of the financial structure optimization.

The objective of the research was to identify the most important theories of the structure of modern financial theory has been to focus on the capture of financial firms in two different stages of their life cycle , so-called growth and ma

Background: Diabetes is a serious risk factor for atherosclerotic cardiovascular disease and an important cause of mortality. Dyslipidemia is commonly related to type 2 diabetes, and the atherogenic index of plasma is a strong marker to predict the risk of atherosclerosis and coronary heart disease.

Objective: To study the association of atherogenic indices lipids in type 2 diabetic Iraqi patients with cardiovascular disease.

Patients and Methods: This clinical study was conducted at Baghdad Teaching Hospital/ Medical City-Baghdad from October 2022 to February 2023. Sixty type 2 diabetic patients were recruited for this study: 30 patients with cardiovascular disease and 30

The protection of public money and its surrounding with special provisions that guarantee that protection from every legal or material assault by the supervisory bodies competent to combat corruption are described as a criminal procedural protection aimed at prosecuting criminals in general crimes and government corruption crimes in particular, and working to recover funds and return them to the state treasury, These agencies operate in an integrated format, each other and in a coherent manner with each other, in order to achieve the purpose of their establishment and reach the basic goal, which is to eliminate corruption from the theoretical side Practical reality.

        Francisco de Quevedo is a well-known man of letters in the Golden Age of Spanish literature. He is the witness who related to us, in his works, the Spanish community  in that era. He showed in most of his writings the political weakness of Spain, and made prominent the remarkable literary aspect of Spain. He had a very good tlent for poetry, and a rather polite  style in exploiting colloquialisms in his literary writings. He wrote about philosophy, where his most prominent work was "The cradle and the grave". The writer was also very well-known for his puns which were employed to clarify his inner thoughts regarding  the Spanish  situation at that time.

Background: There has always been a need for valuable measurements that can be used to measure hearing loss degree in patient who cannot responses to the subjective (behavioral) tests.

Objectives: to examine the accuracy of the click - Auditory Brain stem Response (ABR) test in estimating the hearing loss degree in comparison with the behavioral tests {Free Field (FF)  or Pure Tone Audiometry (PTA )}.

Subjects and method: One hundred twenty one children, with suspected hearing loss, their age between 1-9 year, 51 females and 70 males were examined in this work.
Result: The relationship between the hearing loss thresholds using the behavioral 

     One technique used to prepare nanoparticles material is Pulsed Laser Ablation in Liquid (PLAL), Silver Oxide nanoparticles (AgO) were prepared by using  this technique, where silver target was submerged in ultra-pure water (UPW)  at room temperature after that Nd:Yag laser which characteristics by 1064 nm wavelength, Q-switched, and 6ns pulse duration was used to irradiated silver target. This preparation method was used to study the effects of laser irradiation on Nanoparticles synthesized by used varying laser pulse energy 1000 mJ, 500 mJ, and 100 mJ, with 500 pulses each time on the particle size. Nanoparticles are characterized using XRD, SEM, AFM, and UV-Visible spectroscopy. All the structural peaks determined by the XRD

Separation of Trigonelline, the major alkaloid in fenugreek seeds, is difficult because the extract of these seeds usually contains Trigonelline, choline, mucilage, and steroidal saponins, in addition to some other substances. This study amis to isolate the quaternary ammonium alkaloid (Trigonelline) and choline from fenugreek seeds (Trigonella-foenum graecum L.) which have similar physiochemical properties by modifying of the classical method. Seeds were defatted and then extracted with methanol. The presence of alkaloids was detected by using Mayer's and Dragendorff's reagents. In this work, trigonilline was isolated with traces of choline by subsequent processes of purification using analytical and preparative TLC techniques.

Atorvastatin calcium (ATR) is an antihyperlipidemic agent used for lowering blood cholesterol levels. However, it is very slightly soluble in water with poor oral bioavailability, which interferes with its therapeutic action. It is classified as a class II drug according to Biopharmaceutical Classification System (low solubility and high permeability).
