In this paper we have studied the optical properties of CuBr thin

films.  Different  sample  thicknesses  have  been  prepared  by  using thermal evaporation  technique with 14.4 runlsec as the average deposition rate and 1 00°C as the substrate temperature.

        Polycystic ovary syndrome (PCOS) has a high predisposition to many cardiometabolic risk factors that increase susceptibility to severe complications of COVID-19 and also exhibit an increased likelihood of subfertility. Therefore, women with polycystic ovary syndrome may be disproportionately affected by this epidemic and its related consequences. The accumulation of extra body fat that has the possibility of affecting health is referred to as obesity, which is the outcome of an imbalance between energy intake and expenditure, whereby more calories are consumed than are expended through exercise. This study investigated the relationship between angiotensin-converting enzyme 2 and insulin resistance and other parameters in PCOS

Zinc Oxide transparent thin films (ZnO) with different thickness from (220 to 420)nm
±15nm were prepared by thermal evaporation technique onto glass substrates at 200 with
the deposition rate of (10 2) nm sec

, X-ray diffraction patterns confirm the proper phase
formation of the material. The investigation of (XRD) indicates that the (ZnO) film is
polycrystalline type of Hexagonal and the preferred orientation along (002) plane. The Optical
properties of ZnO were determined through the optical transmission method using ultraviolet-visible spectrophotometer with wavelength (300 – 1100) nm. The optical band gap values of
ZnO thin films were slightly increased from (2.9 - 3.1) eV as the film thickn

The aim of this paper is to design feed forward neural network to determine the effects of
cold pills and cascades from simulation the problem to system of first order initial value
problem. This problem is typical of the many models of the passage of medication throughout
the body. Designer model is an important part of the process by which dosage levels are set.
A critical factor is the need to keep the levels of medication high enough to be effective, but
not so high that they are dangerous.

The morphological description of inner ear in Barbus luteus have been investigated.
The results of the present study revealed that the fish under investigation has a pair of
inner ears which are embedded in two otic capsules of the skull. The inner ear contains two
main structures, the first is the Osseous Labyrinth (OL), and the second is the Membranous
Labyrinth (ML).
Both of (OL) and (ML) consist of three semicircular canal (SCC). These are anterior,
posterior and horizontal semicircular canals (ASCC, PSCC and HSCC).
The (OL) contains three chambers while the (ML) contains saccular structures which
are called otoliths organs represented by utriculus (U), sacculus (S) and lagena (L). Each of
the saccu

        In this study, nickel cobaltite (NC) nanoparticles were created using the sol-gel process and used as an adsorbent to adsorb methyl green dye (MG) from aqueous solutions. The adequate preparation of nickel cobaltite nanoparticles was verified using FT-IR, SEM, and X-ray diffraction (XRD) studies. The crystalline particle size of NC nanoparticles was 10.53 nm. The effects of a number of experimental variables, such as temperature, adsorbent dosage, and contact time, were examined. The optimal contact time and adsorbent dosage were 120 minutes and 4.5 mg/L, respectively. Four kinetic models—an intraparticle diffusion, a pseudo-first-order equation, a pseudo-second-order equation, and the Boyd equation—we

Fusarium wilt is one of the most significant diseases that affects tomato plants and is caused by the fungus Fusarium oxysporum, whether in fields or greenhouses. The current research aimed to identify the Fusarium incarnatum (Desm.) Sacc. agent that causes Fusarium wilt on tomato plants for the first time in Iraq by morphological and molecular methods, in addition to detecting the phylogenetic distance and similarity of the Iraqi isolates to other isolates globally. In January of 2023, the wilt signs were apparent on wilted tomato plants in Al-Mahmoudiya fields in Iraq. The isolate was confirmed and molecularly diagnosed according to the internal transcribed spacer (ITS) region. The se

serum total sialic acid (TSA) in individuals with typhoid fever. The individuals were at age of (35-45) years old and (TSA) was measured by resorcinol reagents. The results showed significant reduction in (TSA) compared to control or normal individuals.

The family of zinc-dependent endopeptidases known as matrix metalloproteinases (MMPs) has been linked to both healthy and unhealthy kidney physiology. Members of the MMP family known as gelatinases (MMP-2, MMP-9) are essential for the degradation of the extracellular matrix (ECM). This effect plays a significant role in the progression of chronic kidney disease (CKD).and as an indicator of chronic renal failure (CRF), which is a permanent loss of kidney function that occurs when the glomerular filtration rate (GFR) falls below 60 ml/min/1.73 m² for more than 3 months. The presented study was established to investigate the MMP-2 and -9 concentrations in the urine and serum among Iraqi patients with CRF undergoing regular weekly dialysis

  Twenty binary liquid crystalline mixture diagrams were investigated with polarizing microscope and differential scanning calorimeter (DSC). Four binary mixture diagrams were constructed to identify the smectic phase which is found to be the same in all components of the homologous series (4-n-alkoxy -2, 3, 5, 6-tetra methyl-4-n-alkoxy azo benzene) (nPA4M). The fifth binary mixture diagram was between the (6PA4M) and the reference liquid crystal compound, terephthlylidene-bis (4-n-butylanaline) (TBAA) to   identify the type of smectic mesophase of these compounds, and the results obtained were compared with the literature.

The master sintering concept is introduced as a unifying sintering model for the initial, intermediate and final stage of sintering. The master sintering curve is independent on the time-temperature trajectory due to account for its integral. The master sintering curve is constructed on a material parameter, which is the activation energy for sintering and other curve shaping parameters, which depends on the initial state of the powder. Literature data of sintering of TiO2 compacts with two initial packing densities of 55% and 69% of theoretical is utilized for the construction of the master sintering curves. The higher initial packing density compact shows higher densification rate, which is reflected by different set of shaping paramet
