Filtration is the process of removing suspended objects from the fluid by passing it through a
porous filter. In this study porous ceramic water filter was preparation from Iraqi local
porcelanite and Iraqi white kaolin with ratio (10%) as a binding material, and natural additives
)wheat flakes( with ratio (5,10,15,20,25, and 30) %. Ceramic materials used in the manufacture
of the filter are environment - friendly materials and harmless. Filter is not expensive and easy
to prepare, the specimens were formed by dry pressing then fired at (1200) ˚C, to evaluation of
prepared filters the following tests were performed, linear shrinkage, loos in mass, apparent
porosity, water absorption, apparent density, permeability as physical properties, compressive
strength and diametrical strength as mechanical properties. The result shows that the linear
shrinkage decreased to 0.6 %, loos in mass increased to 24.25 %, apparent porosity increased
to 55%, water absorption increased to 50.99%, apparent density decreased to 1.07(g/cm3),
permeability increased to 0.131(cm2/ bar. min), compressive strength decreased to 1 (MPa) and
diametrical strength decreased to 3 (MPa) with adding ratio (30%) of wheat flakes (W.F),
scanning electron microscopy (SEM) using to studying the microstructures which showed
homogenies distribution of pores form a net in filter, adding wheat flakes with (30) % give
highest pores.

Ulcer is an inflammatory break reaction in the mucous membrane of stomach. The results
showed non- significant changes in most clinical, hematological parameters depended in the
experiment. While the biochemical; parameters exhibited a significant change. Prevent index
was (27.08%). The level of pH of stomach, volume of gastric fluid, free acidity and total acidity
levels, showed a significant change. Gastric mucosa was more severely affected and showed
more severe and numbers of lesion in those exposed to aspirin alone, then in aspirin and plant
extract. Aqueous – methanol extract of Cordia dichotoma fruit showed mild gastric protection
against aspirin induced ulcer.

A new generalization of faintly continuous function was defined and some basic properties were given. Correlation between faintly simply-continuous function and simply-connected spaces was proved, the property of simply-normal and simply-compact space had been studied.

This review highlighted the biochemical hypolipidemic action of some herbs and medical plants and could submit a good survery regarding intended plants and herbs as well promote and indicate the biochemical functions and importance of natural plants in medicince as a biochemical alternatives with no reverse or side effects. The present study have highlighted the biochemical hypolipidemic action of some herbs and medicinal plants: Daudelion Taraxacum officinale, Basil Ocimum sanctum L., Dill Anethum graveolens, Celery Apium gravedense., Fenugreek Trigonella Foenum-graccum, Grapes Vitis vinifera, Olive tree Olea europea L., Green tea Comellia sinenis, Blue berry Vaccinium angnstifolium juice and Clove Eugenia caryophyllus.

The current study included 926 faecal specimens for children with diarrhea who attended Dohuk Teaching Hospital, Maternity and Children Hospital, and some health centres and local laboratories in Dohuk governorate during the period June 2019 till February 2020 and with exclusively for the 1-12-year age groups. The current study showed that the total incidence of Giardia was 5.16% (52 samples out of 926 samples). It was examined by direct wet wipe and the method of flotation using light microscopy to detect the feeding and parasitic stages of the parasite, which were found in various faecal samples. The microscopic results examination showed that the infection rate among males was higher than that of females, 6.12% and 5. 11%, respectively, the highest rate of infection was recorded in the age group 2-4 years, and the lowest percentage was in the age group 8-10 years, 46. 15% and 5.67%, respectively. As for the monthly distribution of infection, the highest incidence was recorded in June and the lowest incidence was in January, at 10. 09% and 1. 92%, respectively. The infection was twice higher among the residents of rural areas, compared to the urban population with 7.07% and 4. 45%, respectively, and the results of the statistical analysis showed that there were significant differences at the probability level at 0.05.

In this study the magnetic nanoparticles of Co1-XZnXFe2O4 were prepared with different X values (X = 0, 0.1, 0.3, 0.5, 0.7 and 0.9 respectively), using co-precipitation method. The ferrites with a Nano scale was ranging from (10 to28 nm), and the structural properties were tasted prepared samples using X-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM). The structural results showed that the particles have a cubic spindle phase and that the particles have a Nano scale, with a clear agglomeration between the particles sites Finally, the magnetic properties tests showed that the particles have high magnetic saturation.

Two hundred samples of Acinetobacter baumannii have been collected from different types of
infections which included 50 samples from blood, 20 samples from urinary tract infections, 30
samples from wound infections, 40 samples from burn infections and 25 samples from stool
samples from several hospitals in Baghdad city (Central Children's Hospital, Al Karama
Hospital, Karkh General Hospital, Al-Ameen Medical City Hospital, Educational Labs,
Baghdad Teaching Hospital, Child Protection Hospital and Burns and Wounds Hospital).These
isolates have been grown on MacConkey agar and blood agar and then identified by
biochemical tests and also by using API20E and VITEK-2 systems. After identification, 40
isolates have been identified as Acinetobacter baumannii (9 isolates from blood, 1 from urinary
tract infections, 4 from each of wound infections and respiratory tract infections, 8 from burns
and 14 from stool samples). Genotypic detection of some virulence genes of A. baumannii
which included cnf1 and cnf2, showed the presence of these genes in 10 % and 0%, respectively.
Sequencing analysis of cnf1 gene revealed that it has six genetic mutations affecting the
translation of amino acids.
