Because of the contaminants represented by heavy metals in the aquatic
environment have an adverse effects need to be addressed, therefore, a laboratory
simulation was conducted on Cd using kaolinite that collected from Ga’ara Formation
as considered as a natural sorbent material that can be used to remove heavy metals
from aqueous environments. Mineralogical study was conducted on kaolinite using
X-Ray diffraction (XRD), Scanning Electron Microscope (ESM) and Energy-
Dispersive X-ray Spectroscopy (EDS) for the purpose of investigating the microtexture.
It was found that kaolinite has pure phase of very fine grains with a very little
quantity of quartz and has a number of active sites for adsorption. Chemical analyzes
were performed using atomic absorption spectroscopy (AAS), Electron Probe Micro
analyzer (EPMA) and Energy-Dispersive X-ray Spectroscopy (EDS) techniques
confirmed a purity of kaolinite due to high alumina content, except a rare slica content
originated from quartz. Kaolinite sorption efficiency was investigated through a series
of laboratory experiments. The optimal reaction conditions were determined to be as:
pH 5 to 9, but the best is 9, and the eqilibrium reaction time is 40 minutes, and the
solid to liquid ration is 1.25 gm to 50 ml. The effect of the initial Cd concentration on
the sorption efficiency of kaolininte was also investigated and shows that the sorption
proportionally increases with high concentration. All the laboratory experiments
indicate that the reaction is an indothermic.
Concentrated research topic in the study of key variables in the work of the inspectors general offices , which are in the application of quality management standards audit work and reduce the incidence of corruption.

Background: JAK2V617F mutation is the most prevalent molecular abnormality in myeloproliferative neoplasms (MPNs) and has become a valuable marker for diagnosis of MPNs. Almost all patients with polycythemia vera (PV) have this acquired mutation. However, it has also been found in many other hematological diseases, and some studies even detected the presence of JAK2V617F in normal blood samples.
Objectives: To discuss the actual need to defer blood donors with high hematocrit.
Patients and methods: This prospective case control study was started on 16th of December 2012 and completed on 8th of July 2013, and enrolled 94 male blood donors who attended the National Blood Transfusion Center (NBTC) in Bagh
Background: five clinical phases were described in patients with chronic (HBV) infection: HBeAg- positive HBV infection, HBeAg- positive chronic HB, HBeAg negative HBV infection, HBeAg-negative CHB and occult HBV infection. Aim: This study aimed to determine the incidence of the unclassified phase (gray zone) in chronic hepatitis B patients and its significant in the clinical practice. Patients and methods: The study was conducted retrospectively on 109 patients' who have HBsAg positive for more than 6 months. The data recorded include; HbeAg and anti-HBe Ab, ultrasound of the abdomen, HBV DNA load and alanine aminotransferase (ALT), accordingly; we classify the patients to known clinical phases. Patients who were unfit one of these phases

The game theory has been applied to all situations where agents’ (people or companies) actions are utility-maximizing, and the collaborative offshoot of game theory has proven to be a robust tool for creating effective collaboration strategies in a broad range of applications. In this paper first, we employ the Banzhaf values to show the potential cost to waste producers in the case of a cooperation and to reduce the overall costs of processing non-recyclable waste during cooperation between producers. Secondly, we propose an application of the methodology to study a case for five waste producers' waste management in the Al-Mahmudiya factory with the aim of displaying the potential cost to waste producers in case of cooperatio

The current study aims to determine the prevalence of Trichomonas vaginalis and Candida spp., and also to identify Candida parapsilosis and some virulence genes. It was conducted in Bint Al-Hoda Hospital of Maternity and Children in Thi-Qar province, south of Iraq for the period from the beginning of January to the end of December 2020. Two hundred and fifty samples were collected from the female genital tract for women whose age ranged between 17-50 years. Microscopic, traditional and molecular tests were used in the sample examination. The results recorded 12 (4.8%) samples infected with T. vaginalis parasite, whereas 130 (52%) samples showed Candida yeast distributed as follows: 75 (30 %) <

Agricultural chemicals on a large scale of use throughout the world, and there are many studies about these chemicals and its disadvantages, but most of them were limited to its impact on mammals such as rodents in determine. This study was designed to determine the impact of these chemicals on DNA damage for E. coli bacteria from Iraq. The DNA is similar in terms of structure and function in all living organisms with a different in number and sequence of the nitrogenous bases among living organisms. This study showed that snails and slugs killer material Metaldehyde are strongly bind with the DNA extracted from bacteria, and herbicides Glyph

These principles have been planted in the conscience and conscience of man, and it is the principle that is considered to be an inextricable right with the existence of human in the collective relations between humans in general and members of a group of groups or conglomerates unintentionally organized but created by circumstances. Accordingly, all international and domestic legislations considered it to be a human right, especially in relation to equality in the right to work, equality in other rights and what is associated with the remuneration of work (wages) and related to its attachments and leave.

Back ground: Oral isotretinoin is recommended
for sever nodulocystic acne in the doses 0.5-
2mg/kg/day which is usually associated with higher
incidence of adverse effects. To reduce the
incidence of side-effects and to make it more costeffective,
the lower dose regimen of isotretinoin has
been used.
Aim: To compare the efficacy and tolerability of
oral isotretinoin 10mg and 20mg/day in acne
vulgaris.
Methods: one hundred and twenty patients with
acne vulgaris were randomized into two treatment
regimens each consisting of 60 patients. The first
was treated with 10mg/day and the second group
with 20mg/day for 24 weeks. Fifty five patients
from the first group and 47 patients from the second
