This current study was conducted an agricultural nursery in the Al-Muqdadiya district which is in the north of Baqubah, the center of Diyala governorate and lies 90 km north east of the capital Baghdad. The experiment was done in autumn on capsicum annuum L, Hybrid Barbarian F1, the Indian origin. It aimed to investigate the impact of treatment with melatonin and glutathione on the Vegetative features of capsicum annuum L grown under polluted conditions with cadmium. The experiment was carried out according to Randomized Complete Block Design (R.C.B.D.) in three replicates. It includes three transactions, these were cadmium which was added to soil with the two concentrations 0 and 15 mg.kg soil-1, whereas melatonin and glutathione were added spreading on the leaves with the concentrations 0,50, and 100 mg.l-1. The results showed a significant decrement in plant height, number of leaves, and leaf area as a result of treating the agricultural soil with cadmium at a concentration of 15 mg.kg soil-1, compared to the treatment without the addition of cadmium, i.e. the control treatment. It was also shown from the results obtained that there was a significant increase in all the studied traits as a result of spraying the plants with melatonin and that the highest average for each of the plant height, number of leaves, and leaf area was obtained as a result of spraying the plants with melatonin at a concentration of 100 mg. l -1. Significant increases were also obtained in all the traits under study as a result of spraying plants with glutathione at a concentration of 100 mg.l-1.

Background: Pseudomonas aeruginosa is one of the most common Gram-negative bacteria responsible for outbreaks of infection and morbidity in hospitals. The difficulty in treating them lies in their possession of a wide range of virulence factors in addition to their ability to have natural and acquired resistance to antibiotics especially the multi-drug resistance (MDR) ones. Material and Methods: 114 samples were collected and isolated from burns and wounds patients hospitalized in Baquba Teaching Hospital, during the period from September to December 2022. These isolates were diagnosed using conventional diagnostic methods, microscope diagnosis, and biochemical tests, and then the final diagnosis was made using the VITEK2 compact system device. Results: 43 isolates 42% were obtained from the total collation samples of P. aeruginosa. A test was conducted to detect the ability to from biofilms, and the results were as follows: (Strong adherent 41%, n=7), (Moderately adherent 23%, n=4), (Weakly adherent 35%, n=6), and they were tested for sensitivity towards 12 antibiotics, and the results were as follows: AMC 96%; CAZ 100%; CTX 100%; CRO 100%; FEP 75%; MEM 76%; AK 82%; TOB 76%; GN 70%; E 94%; PB 23%; CIP 47%. 17 of them were isolates with multidrug resistance (MDR). Sequence analysis was used to detect the presence of (pslD, pslA, rhlR) genes in 17 isolates of P. aeruginosa, and the obtained results were as follows: the presence of the pslD gene at arte of (94%; n=16), the pslA gene at rate of (100%; n=17), and the rhlR gene at rate of (100%; n=17).

In this research, the NiFe2O4 and CuFe2O4 nanoparticles nanoparticles were synthesized by sol-gel auto combustion technique and diagnosed by various techniques such as infrared (FTIR), X-ray diffraction (XRD) and Field Emission Scaning Elecron Microscopy (FESEM). Diagnostic results showed obtaining (Ni and Cu) nanoparticles. Then (PVA, NiFe2O4/PVA and CuFe2O4/PVA) films were prepared and the electrical conductivity was studied for the prepared films by LCR device. The electrical conductivity are (8.93E-09, 1.49E-05 and 7.00E-06) for (PVA, NiFe2O4/PVA and CuFe2O4/PVA), respectively. Nickel and copper ferrite nanoparticles showed a apparent increase in electrical conductivity for the pure polymer.

Two solvent extracts (Methanol and aqueous) of Rosmarinus officinalis were estimated for their antibacterial action against three types of bacteria that cause food poisoning (Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus). The results revealed that the alcoholic extract of Rosemary has significant antibacterial action against bacterial infections compared with aqueous extract.. The phytochemical examination revealed the presence of (alkaloid, carbohydrates, phenols, flavonoids, tannins, proteins and saponins only in the aqueous extract). Additionally, (DPPH assay) for the antioxidant analysis was also carried out using the two extracts of which alcoholic extract showed exceptional antioxidant activity. The results show that , it is clear that in the upcoming Rosemary plant may pave the way for designing the new medicines for controlling bacterial diseases.

This paper discusses the use of a biometric system for secure authentication based on deeper exploration in hand vein patterns to derive more reliability as a good biometric trait. The proposed system identifies internal hand vein patterns, and also identifies individuals correctly throughout their lifetime. The proposed system follows a three-phase approach comprising data processing, feature extraction, and feature evaluation. For the advanced filtering techniques in a dataset of 420 hand vein images, the approach goes to Box filters, HFEF, and CLAHE, then to discrete cosine transformation and image fusion. The features are extracted through PCA Net for acquiring the most distinctive attributes of hand veins. The different machine learning algorithms used in this evaluation for classification of the extracted features include SVM, Logistic Regression, and Naive Bayes. Results indicate highest accuracy for Logistic Regression algorithm (99.7%) and SVM algorithm of (99.6%). However, Random Forest algorithm has an accuracy of (98%), while Naive Bayes algorithm shows poorer accuracy of (91%).
