Detergent is one of the pollutants that poses significant threats to ecological systems. Detergents can also dissolve in wastewater and negatively impact the efficiency of wastewater treatment facilities. They are used for a variety of functions, most notably hygiene, and are an integral aspect of human life. This means that there are a variety of routes by which detergent components can reach the environment. In this Study, twenty-three detergent samples from local markets in Baghdad. The aim of this study is to investigate the concentration of heavy metals Cobalt (Co), Chromium (Cr),Lead (Pb),Zinc (Zn), Iron (Fe) and Cadmium (Cd) in some detergents using Atomic Absorption Spectrophotometer. The results of the concentration of heavy elemen

In this paper, two new simple, fast and efficient block matching algorithms are introduced, both methods begins blocks matching process from the image center block and moves across the blocks toward image boundaries. With each block, its motion vector is initialized using linear prediction that depending on the motion vectors of its neighbor blocks that are already scanned and their motion vectors are assessed. Also, a hybrid mechanism is introduced, it depends on mixing the proposed two predictive mechanisms with Exhaustive Search (ES) mechanism in order to gain matching accuracy near or similar to ES but with Search Time ST less than 80% of the ES. Also, it offers more control capability to reduce the search errors. The experimental tests

Rivest Cipher 4 (RC4) is an efficient stream cipher that is commonly used in internet protocols. However, there are several flaws in the key scheduling algorithm (KSA) of RC4. The contribution of this paper is to overcome some of these weaknesses by proposing a new version of KSA coined as modified KSA . In the initial state of the array is suggested to contain random values instead of the identity permutation. Moreover, the permutation of the array is modified to depend on the key value itself. The proposed performance is assessed in terms of cipher secrecy, randomness test and time under a set of experiments with variable key size and different plaintext size. The results show that the RC4 with improves the randomness and secrecy with

The influence of Toxoplasma gondii on some biochemical parameters has lately gained an increasing attention. The aim of this study was to assess the levels of some biochemical parameters in Toxoplasma positive and negative subjects. An analytical case–control study was achieved in Baghdad for the period from October 2018 until March 2019. Forty nine females participated in this study, with an age range of 18-55 years. The participants were separated into two groups, namely Toxoplasma positive subjects (n=21) and Toxoplasma negative subjects (n=28), based on enzyme-linked immunosorbent assay (ELISA). Blood and serum samples were collected from all subjects to evaluate the serum levels of cholesterol,

The present study was aimed to biosynthesis of silver nanoparticles by using rhaminolipid produced from local isolate Pseudomonas aeruginosa as reducing and stabilizing agent. Silver nanoparticles (AgNPs) synthesized by green method have shown several applications such as biomedical, anticancer, bio sensing, catalysis etc. Characterization study of purified bioemulsifier using thin layer chromatography (TLC) was demonstrated that the biosurfactant contains mono, and di- rhamnolipid with Rf values of 0.86 and 0.36 respectively. Optimization results of biosynthesis silver nanoparticles were revealed that an increasing in intensity of Surface Plasmon Resonance (SPR

 This study was aimed to displayed effect of this nanoparticles on pregnant mother and embryos. All females administration of AgNPs suspension orally during the gestational period (for 21day) in two doses low 2mg and high dose 20 mg /Kg body weight and the control group received D.W only. The pregnant females (60 females) include the control group and the treated group  was subdivided in to two groups, pre and post implantation and all the mothers weighted along the study. The embryos and their brains after retrieved weighted and the crow-rump length (CRL) measurement also. The results showed that the active form of Ag can be transport the placental barrier and blood brain barrier (BBB). This nanoparticles showed advers

This research was aimed to study the pollen morphology for the genus Pterocephalus(Vaill)  from Dipsacaceae family in Iraq, and to utilize these feathers in isolating the species as valuable taxonomic traits for enriching Iraqi flora. The study included characteristics of the type, shape, size, sculpturing and apertures, as well as determining the full dimensions using light microscopy as well as numerical analysis of this species and draw polygonal shapes and denderogram  convergence between species. The results of the study of pollen and polygonal forms showed significant differences in the characteristics at the level of each species, which helps to identifi

This study was aimed to measure the decolorization of tattoo dyes by different chemicals and polyphenol oxidases from several plant sources. The tattoo inks removal market has burgeoned over the years, due to increased spread of tattooed persons about the world. Laser and surgery are presently the gold standards for removing of the tattoo. However, both of them have blemishes. Consequently, lots of persons were preferring easier, faster and cheaper procedures for tattoo remove. In this study polyphenol oxidases enzyme from many plant sources and different chemicals were used for decolorization of tattoo dyes in vitro. The polyphenol oxidase enzyme was used for removing of tattoo dyes (brown and blue) in order to demonstrate their

This study was aimed to purified and characterized  the  bacteriocin produced from Lactobacillus acidophilus HT1,  in order to use it in a skin pharmaceutical formula. The optimal conditions for bacteriocin production was investigated and results showed that modified nutrient broth was the best medium with glucose (30 gm/L) and yeast extract (7 gm/L) with peptone (7 gm/L) were the optimum carbon and nitrogen sources. In addition, 2% inoculum size, 37C◦ and pH 6.4 were the optimal conditions to obtain maximum bacteriocin

This study was depend to select Pseudomonas aeruginosa A3 as a good producer of rhamnolipid (RL) biosurfactant after screening on agar plate where it was able to biosynthesize 4.3 g/L with emulsification index 52% and reducing the surface tension of water to 33.2 mN/m. Therefore, this study was aimed to increase the production of biosurfactant from selected isolate by exposure to several physical and chemical mutagenic factors like gamma radiation, nitrosoguanidine, ethyl methane sulfonate and lithium chloride. The results were shown that 0.2 g/L of nitrosoguanidine was the best mutant for increasing the production to about 2 folds (9.4 g/L) after 15 mins exposure to this material, as well as the emulsification index and

Variety of virulence factors are involved in the pathogenicity of Escherichia coli isolates, the common cause of the urinary tract infections.(UTIs). This study was aimed.to determine some virulence factors.involved in the pathogenicity.and the phylogenetic.grouping of uropathogenic E. coli isolates.from UTIs in compare.with isolates.from gut.microbiota (fecal flora) In.this study ,E coli isolates  were collected from  samples .urine (n = 25), fecal samples (n = 25) samples of  the same patients with UTI, and from fecal samples (n= 5 as control )of patients without UTI. The detection of phylogenetic grouping and some virulence genes among the all isolates were confirmed by PCR technique. The resul

Carbon monoxide (CO) contamination represents a major global concern. This study aimed to detect the concentration of CO, emitted from various vehicles exhausters which are important contributors in deteriorating air quality. The data was collected throughout the heavy parking period at Al- Jadyria campus in Baghdad University. The vehicles were classified into two main groups according to the type of gasoline they are filled with; including premium leaded and leaded free gasoline (PLG and LFG respectively), as well as engine size, odometer, brand and model. Seven low duty vehicles for each engine size (<1.6 to >2.0) liter were selected randomly. A portable gas detector type (Altair® 4X) was used to measure exhausted emiss

The aim of this study is to develop a bioconversion process of chitin to chitosan in solid-state fermentation. A classical optimization of one factor at the time was performed and revealed that maximum chitin deacetylase (CDA) production can be obtained in corn medium moisturized with mineral salt solution and with an initial moisture of 1:1 level (w/v).
