Studying some of the optimal conditionals for the best bacterial isolates from soil and its effects on their growth rates
...Show More Authors
Abstract<p>The current study aimed to use some bacterial isolates from the local soil of Baghdad city by study the effects of temperature, pH and incubation period on the growth rates of isolated bacteria and choose the optimal conditions for their diversity and for understanding bacterial growth and their requirements for survival and proliferation. This information can be applied to obtain their high growth rate for use in various fields such as agriculture, medicine and environmental sciences in the future. And it used to assess the degree of variation in across bacteria species in pH, temperature and incubation period. A number of local bacterial isolates as <italic>Enterobacter cloacae</italic>, <italic>Aeromonas hydrophila, Pantoea spp.</italic>, <italic>Pseudomonas mendocina</italic> and <italic>Serratia fonticola</italic> identified in this study. The growth rate of the bacterial isolates was tested by growing each bacterial isolate in a different range of pH (4, 7 and 10) and under the influence of several temperatures (52, 35 and 50) and within different incubation periods (24, 48 and 72) hours The optimal conditions were determined by measuring the optical density (absorbance) at a wavelength of 600 nm, which represents bacterial growth. The optimal conditions for <italic>E. cloacae</italic> were determined to be a pH of 10 and a temperature of 35°C after a 72hour incubation period. Similarly, <italic>A. hydrophila</italic> exhibited optimal growth at a pH of 7 and a temperature of 35°C after a 72hour incubation period. <italic>Pantoea</italic> spp. demonstrated optimal growth at a pH of 7 and a temperature of 25°C after a 24hour incubation period. <italic>P. mendocina</italic> displayed optimal growth at a pH of 7 and a temperature of 25°C after a 72hour incubation period. Lastly, <italic>S. fonticola</italic> exhibited optimal growth at a pH of 7 and a temperature of 50°C after a 72hour incubation period.</p>

Effect of some plant extracts on germination and seeding of Raphanus sativus and effect on surface growth of Rhizoctonia solani
...Show More Authors

The experiment was conducted to study the effect of leaves extract of Salvia sclarea , Rosmarinus officinalis and Thymus vulgaris with 10% and 30% concentration on germination of seeds and growth of seedlings . The effect of these extracts on infection percentage of seeds decay and surface growth of Rhizoctonia solani . The results showed that the three extracts effected significantly to reduced percentage of seeds germination, acceleration of germination , promoter indicator , infection percentage of seeds decay and surface growth of R. solani especially in 30% concentration .

Genotyping of fusA Gene from Clinical Isolates Acinetobacter baumannii in Baghdad
...Show More Authors

This study aims at detecting the differences in genotyping of coding region fusA gene in clinical isolates of Acinetobacter baumannii from Baghdad, Iraq. Collected two hundred clinical samples (50 samples from urine, 50 samples from wound, 50 samples from sputum and 50 samples from otitis infections). Laboratory diagnosis for bacterial isolates carried out by some biochemical tests and confirmed by using VITEK- 2 compact system. The results appeared that twenty isolates of Acinetobacter baumannii in all these samples. Genotyping study was performed of coding region fusA gene of the extracted genome of all bacterial isolates and used specific primers in achieved amplification process of this target gene. DNA sequencing of this gene and alig

A Survey Study Of A Sample Of The Public Of Baghdad  Governorate

The current study aimed to identify the most prominent psychological and behavioral repercussions of the exposure of the elderly to the news of the Corona pandemic and to determine the mechanisms of their exposure. On an intended sample on both sides of (Al-Karkh and Al-Rasafa) and the simple random sample was adopted to choose the place of distribution of the questionnaire and the intentional sample.

 The research concluded several results, most TV news is still a primary source of information and that most of the sample move between stations to see more information about the pandemic and that the presentation of views confuses the elderly ،There

Synthesis of zinc nanoparticles by laser induced plasma and its effects on levels of thyroid hormones
...Show More Authors

In the present study, the effect of Zinc nanoparticles on levels of (T3 , T4 and TSH) hormones was investigated. Zinc nanoparticles were synthesized by Laser induced plasma.The Nd: YAG Nd: YAG laser with a wavelength of 1064 nm was used to generate nanomaterials of the elements (zinc) upon collision with target atoms. Plasma generated by different laser intensity is generated. After confirming the preparation of zinc nanoparticles, XRD, AFM was examined, and the effect of these substances on the thyroid gland (T3, T4, TSH) was observed for two doses of each component (1 ml / kg, 4 ml / kg) after conducting a cytotoxicity examination of the lymphocytes of the rats extracted from Rat spleen was 1.8% less toxic to zinc, and as noted The
