This study describes the determination of some phenols in four different zones of Tigris river in Iraq including, AL-Krieat, AL-Kadhimiya, AL-Jadiriyah, and AL-Adhamiyah. The phenolic compounds analyzed were (2,3-dimethylphenol, 4-chlorophenol, 3-nitrophenol and 2,4-dinitrophenol) using reverse phase high performance liquid chromatography (RPHPLC) with a UV detector on ODS-C18 column(150×4.6 mm I.D) and a mobile phase consisted of methanol-water(30:70)%(v/v) at pH 5.0, and a column temperature at 30C° with 20 µL injection. UV detection helps to identify different phenols at wave length at 280 nm with a flow rate at 0.5 ml/min. The separation time was (< 6) min.The results indicated that the AL-Adhamiyah zone contains the highest concentration of 3-nitrophenol (0.094 µg/mL), while the AL-Jadiriyah zone recorded the lowest concentration of 3-nitrophenol (0.056 µg/mL).On the other hand the other phenolic compounds studied did not record any concentration in four zones of Tigris river. The values of correlation coefficient and accuracy were calculated for 3-nitrophenol, the graph was linear with very good correlation coefficient (R2>0.9999).
The dry weight of the liver of Rana ridibunda was expressed as percentage of the dry
weight of the body. The female liver weight always exceeds that of the male, except in July
and September. The difference between males and females for the whole year, regardless of
months, was not significant. Livers of both sexes were relatively large prior to hibernation
(December), decreased during hibernation (January and February) until a minimum weight in
March (post-hibernation).
The increase of liver weight during December is apparently simply to meet the metabolic
requirements for survival during hibernation. The percent reduction in liver weight during
hibernation was 1.081% in males and 1.356% in females. The decrease
Background: Breast cancer is the most frequent cancerous tumor and major cause of death from cancer between women all over the world.
Objectives: is to assess if ultrasound features of breast cancer can predict its histopathological grade and HER2 status of breast cancer for patients had their diagnosis in Oncology Teaching Hospital in Medical city complex from September 2014 to November 2015
Patients and Methods: This is retrospective study of 102 patients whom histopathologically proved breast cancer had reviewed their ultrasound findings and correlate them with histopathological grade and HER2 status.
Results: well circumscribed lesions, poorly defined and spiculated lesions are more likely to be of intermediate to high grade
In the present study, male albino mice were used to estimate the effects of titanium dioxide nanoparticles (TiO2) suspension used in two doses (150, 600 mg/kg) through intraperitoneal route. The results revealed a significant difference (p≤0.05) among the control and experimental groups in all haematological parameters, including a significant increase in White Blood Cell (W.B.C) count, Mean Cell Volume (MCV), Mean Cell Haemoglobin Concentration (MCHC), and Mean Cell Haemoglobin (MCH). Also, the results showed a significant decrease in Red Blood Cell (R.B.C.) count and Haemoglobin (Hb). Biochemical tests included AST and ALT and showed a significant elevation in all exposed groups, while ALP was

Objective: To evaluate whether the SOX2 protein could be used as a predictor in patients with GC and to assessment the correlation between the IHC expression of the SOX2 protein and the various clinic pathological Parameters as age, sex, histopathological subtypes, grade and stage of the tumor by immune-histochemical Technique. This is a retrospective study conducted on 60 randomly selected patients (30) normal versus (30) GC, at the pathology department of the Gastroenterology and Hepatology Teaching Hospital & some private hospitals. It were collected and diagnosed during the period between from 2014 to 2018. From each block were stained with H&E and IHC stained for SOX2. The Statistical analysis was done using SPSS system, and the differ

Polycaprolactone is one of the natural biodegradable polymers mainly used in bioplastics production for packaging, usually composed of non-toxic compounds and biodegradable. The aim was to examine the role of zinc oxide (ZnO) nanopowder on the,wettability , thermal and anti-bacterial effect nanocomposites. Pure PCL and PCL-based bio- nanocomposites doped with various ratios of ZnO nanoparticles from 0% to 5wt% were prepared through the arrangement of throwing procedure. The results show that wettability properties in relation to ideal PCL and that they were increasingly hydrophobic from 57º.8 to 69º.53 because add ZnO nanocomposites,the thermal stability between 300 and 400 ° C makes them perfect for the application

Background: Congenital defects in continuity of the intestine are morphologically divided into either stenosis or atresia and constitute one of the most common causes of neonatal intestinal obstruction.
Patients and methods: This is a prospective study for analyzing (60)neonates with jejunoileal atresia who were managed at Children Welfare Teaching Hospital in Baghdad over a three years peroid extending from 1st January 2004 to 1st January 2007.
Results: Thirty six patients (60%) had jejunal atresia while ileal atresia was in(24) patients(40%).The most common type of jejunoileal atresia was type IIIa (38.3%) of the cases and the second was the type II (25%).The clinical presentation for jejunal atresi

Our main interest in this study is to look for soft semi separations axioms in soft quad topological spaces. We talk over and focus our attention on soft semi separation axioms in soft quad topological spaces with respect to ordinary points and soft points. Moreover study the inherited characteristics at different angles with respect to ordinary points and soft points. Some of their central properties in soft quad topological spaces are also brought under examination.
A high power N2 laser of the three stage-Blumlein circuit designed, which consist two identical electrodes, four capacitors and three spark gaps which designed discharge geometry with minimum inductance. This system gives a maximum energy 18 mJ with a pulse time 6.65 ns and wave length 337.1 nm. The distance between spark gap terminals has large effect on the output energy. The ideal distance were 11 mm between the terminals for the first spark gap and 4 mm between the terminals for the second spark gap, the distance between the terminals of the spark gaps has a significant effect on the resulting energy, where the energy decreases when the distance between the terminals of the first and second s

Adsorption techniques are widely used to remove certain classes of pollutants from waters, especially those that are not easily biodegradable. Dyes represent one of the problematic groups. The removal of methyl green from waste water using bamboo was studied in batch and continuous system. In batch system equilibrium time and adsorption isotherm was studied at different concentrations (5, 10, 15, 20, 25 and 30 ppm) and 50 mg weight of adsorbent.
Langmuir and Freundlich equations were applied for adsorption isotherm data. Langmiur equation was fitted better than Freundlich equation (R2=0.984 for Langmuir equation).The maximum percentage dye removal obtained 79.4% and adsorption capacity was 15.5 mg/g. For continuous system the breakthr
