An experiment was conducted to study the effect of four isolates of Pseudomonas spp. on the growth of two plants Radish & Cowpea and on the concentrations of macro elements & microelements . This experiment included two parts , the 1st. part included isolation and characterization of 4 isolates of Pseudomonas bacteria from local Iraqi soils Baghdad . The 2nd part included planting two plants Radish & Cowpea in plastic pots size 5Kg -soil in the green house Biology Dept. College of Science , after planting we added the isolates to the pots , and after 50 days, the growth parameters length , fresh and dry weight , percentage of germination were recorded , and the concentrations of macro elements Mg ,P ,K ,Fe, and Ca ,and microelements Zn ,Cl ,Mo ,Cu ,and Ba. The results showed that the bacterial isolates were effective in promoting the growth of two plants comparing with control plants , the concentrations of maco & microelements were increased in both plants after adding the bacteria to the plants. Results were analyzed statistically using the least significant difference and at the level of probability of 0.05.
Nerium oleander known as oleander has belonged to the poisonous plants its habitat in a tropical andsubtropical region. The chemical analysis with GC-Mass of the alcoholic extract of oleander leaves revealedthat this plant has many chemical compounds more than 80 compounds and high-peaks about 29 compoundswhich are represented by alkaloids, phenol, terpenes, and fatty acid. HPLC analysis showed many essentialoils that have many biological effects.To evaluate the antibacterial activity of the alcoholic extract of N. oleander against locally isolatedPseudomonas aeroginosa the broth micro-dilution method was adapted to different concentrations werestarted from 3.9 to1000 mg/ml. The results revealed that the alcoholic extract has antiba

Phonetic-physiological principle is the main parameter by which the elements and criteria of cognitive activity in the presented study are distinguished. On the basis of the above mentioned parameter, we select the investigated criteria and elements. The first criterion is semantic, reflects the accordance of the elements of thinking to sound combinations in the studied languages, and allows us to distinguish the second criterion – morphonological. The second criterion depends on the phonetic changes of these combinations occurring in the process of speech activit

Show MoreThe main idea of this paper is to define other types of a fuzzy local function and study the advantages and differences between them in addition to discussing some definitions of finding new fuzzy topologies. Also in this research, a new type of fuzzy closure has been defined, where the relation between the new type and different types of fuzzy local function has been studied

Out of 120 isolates from different clinical cases, only 75 were found and confirmed that they belong to the Pseudomonas aeruginosa bacteria. The result revealed that the LasB virulent gene was present in 63 isolates with 63% percentage. The gel electrophoresis showed that the molecular weight of LasB gene was 300 bp. DNA sequences of LasB gene was done, and the results showed the presence of some gene mutations like substitution, addition and deletion with 97% identity with the Refseq gene. From the other side, the results of identities of translated nucleotides sequence with the original sequence of amino acids revealed that there are no effects of gene mutations on translation of the product protein.
Acinetobacter baumannii (A. baumannii ) is considered a critical healthcare problem for patients in intensive care units due to its high ability to be multidrug-resistant to most commercially available antibiotics. The aim of this study is to develop a colorimetric assay to quantitatively detect the target DNA of A. baumannii based on unmodified gold nanoparticles (AuNPs) from different clinical samples (burns, surgical wounds, sputum, blood and urine). A total of thirty-six A. baumannii clinical isolates were collected from five Iraqi hospitals in Erbil and Mosul provinces within the period from September 2020 to January 2021. Bacterial isolation and biochemical identification of isolates

This experiment was carried out in the greenhouse of Al-Adawi area of the Damascus Governorate, and labs of the Horticulture Department, Faculty of Agriculture, Damascus University during the period 2020-2021, to study the effect of biofertilizer, Em1 (0, 4, 8 ml/l), and seaweed extract, Alga 600 (0, 1, 2 g/l) and their interactions on growth and productivity of strawberry plant cv. Festival. data were calculated after six months of culture. The combination treatment of Em1, (8 ml/l) and Alga 600 (2 g/l) resulted in the best morphological parameters (23,93 cm, 27.87, 138.81 cm² for plant height, leaf number, and area respectively), physiological parameters (10.30 %, 60.00 mg/100 gm wet weight, 0.59 % for total soluble solids, v

The Experiment was conducted during the fall of 2002-2003 at the botanical gardenor of biology Department, Ibn- Al Hiatham Education college Baghdad University to study the effect of two planting dates (23/10 and 6/ll 2002) with different concentrations of GA3 (100 and 200 ppm) on growth characters and the active material of two cultivars (Local and German) of chamomilla (Matricaria chamomilla L.) plants. Randomized complete Block Design (R.C.B.D.) was used with three replications . Each one of the experiment units 1x1m .The parameters study were plant height, no shoots, no inflorescence branches and nodes , leaf area and leaf area index and violate oil percentage. The result showed that planting date. At 23/10 give a significant
