Forty meat samples were collected from different places in Diyala province (20 samples for
each of the regular slaughter and meat slaughtered in the streets). Bacterial community detection
were done via using suitable media. The results indicated Staphylococcus aureus isolates were
30% and 90% that isolated from meat samples that were taken from slaughter houses and street
slaughtered respectively. Isolation percentage of E.coli were 20% and 30% that isolated from
slaughter houses and street slaughtered respectively. Isolation percentage of Klebsiella spp
were 10% and 70% of meat samples that isolated from slaughter houses and street slaughtered
respectively. Pseudomonus spp isolation percentage was 10% from street slaughtering meat
samples. The Street slaughtered meat was highly contaminated as a comparative with that meat
came from slaughter houses. This study proved that the Erythromycin was highly effective
against Staphylococcus aureus, Ampicloxacilline was highly effective against Escherichia coli
and Klebsiella was highly affected by Tetracycline.

The research includes a study of evaluating the treatment efficiency of the sewage plant in the
Tuz Khurmatu district during the period from September 2020 to July 2021. Three study sites
have been selected. The study includes measuring certain physicochemical and biological
properties of water (the biological properties include studying the quality of algae). As for the
physicochemical properties, they include measuring (air and water temperature, pH, dissolved
oxygen, biological oxygen requirement (BOD5), active phosphate and active silicates).
The results found that air temperature ranges between 12- 49°C, while the water temperature
ranges between 9- 40°C. The pH values have a wide range during the months of the study
ranging between 6.20 - 8.45. The values of the dissolved oxygen range between 1.25-3.10 mg/L,
and the values of the biological requirement for oxygen range between 19.2- 47.2mg/L. The
study also shows that the wastewater during the study period is of a light basicity in which
bicarbonate ions prevail. Nutrient concentrations fluctuate depending on the nature of the site
and the date of sample collection, as the effective phosphate ranges between 2.32-7.76 mg
phosphorous-phosphate/liter. As for the silicate values, they range between 0.38- 6.61 mg atom

Acinetobacter baumannii carries modifying enzymes, are resistant to many broad-spectrum
antibiotic, including: - Amikacin, Tobramycin and Gentamycin (Aminoglycoside), the genes
that encode the Aminoglycosides enzymes was aadA1 and aacC1 genes confer resistance to
anti-group aminoglycoside.
Two Hundred clinical samples were collected from different sources of infection included
(50 sample of blood, 55 sample of sputum, 50 samples of Urine , 10 samples of wound, 10
samples of burn ,10 samples of throat swab and 15 samples of body fluid from plural infusion).
Clinical samples were cultured in different media, Blood agar, MacConkey agar and CHROM
agar and incubated at 37°C for 24–48 h. for diagnosis used biochemical tests including (oxidase
and catalase) and microscopic examination, for final detection using Vitik2 compact system
and API 20E . After identification we obtained 40 isolates of Acinetobacter baumannii,
including 14 isolates from blood (35%) , 15 isolates from sputum (38%) , 4 isolates from wound

In this paper, we recall the results related to the quadratic family of pseudo-differential
operators, and we gave similar results for to the cubic family of pseudo-differential operators,
also we benefited from the facilities obtained by using the pseudo-differential operators. We
define the pseudo-differential operator on Rn by using some particular kind of functions known
as symbol with some examples. At the end, we explain the hypotheses on the class of symbols
and minimal decreasing ray to prove the existence of a total system of eigenvectors

The current study investigated that malignant breast cancer (BC) was shown to be associated
with a single nucleotide polymorphism (SNP) on chromosome 12 in the IL-12 subunit p40 gene
(rs3212227, A/C) malignant BC. In an Erbil city case–control research involving 140 infected
persons and 70 healthy women, the allelic and genotypic occurrences of SNPs were examined.
Having the minor allele (A) raised the chance of getting malignant BC by a whopping 109%
(95 percent confidence interval [CI]: 0.68 to 1.74). P < 0.05; OR = 0.92; 95 percent confidence
interval [CI]: 0.57 to 1.47) was found for the primary allele (C). Genetic assessments in the
current study have found that homozygosis in the CC and AA allele groups (P< 0.05; OR =
1.06 & 0.94, 95 percent confidence intervals: 0.54 to 2.06 & 0.46–1.91) was related with a
developed hazard of malignant BC, while the CA allele group (P< 0.05, OR = 0.80, 95 percent
confidence intervals: 0.37–1.70) was associated with a lower risk. There was no link between
the heterozygous genotype and breast disease in the research. There may be a link between the
A allele's increased production of IL12B p40 mRNA and an increased risk of BC, but further
research is needed to confirm this
