Effect of Annealing Temperature on Structural and Optical Properties of CdS Thin Films Prepared by CBD and Thermal Evaporation Techniques

Mohammad Ali; Saeed J. Abbas; Alaa S. Al-Kabbi

Journal of Basrah Researches (Sciences), Volume 45, Issue 1, Pages 1-14

The CdS thin films were deposited on glass substrates by two different methods, chemical
bath deposition (CBD) and thermal evaporation (T.E.). The effect of annealing temperature on the
structural and optical properties of the CdS thin films were investigated. The structural properties of
CdS thin film was studied by X-ray diffraction. It was observed that the films have a polycrystalline
hexagonal (wurtzite) structure with preferred orientation along (002) plane. The crystallite size
calculated from XRD increases as the annealing temperature is increased. We observed that the
lattice constant, micro strain, dislocation densities and number of crystallites per unit area of the
films are quite different in these processes from XRD analysis by considering high intense
diffraction peaks of the as-deposited and annealed films. The energy band gap in nanocrystalline
CdS thin films has been estimated from absorption measurements. The band gap values for CBD-
CdS thin films decreased from 2.75 to 2.45 eV and for T.E.-CdS thin films decreased from 2.60 to
2.43 eV with increasing annealing temperature. Small nanocrystals display wide band gaps as a
result of the quantum confinement experienced by nanocrystals of a certain size.

Journal of Basrah Researches (Sciences), Volume 45, Issue 1, Pages 14-31

    Currently, chalcone derivatives are an interest research for the designing a new compounds as anticancer agents due to the privilate structure of chalcone compounds in the drug discovery system. In this study, we synthesized 5 chalcone derivates which are (CH (A) , CH (B) , CH (C) , CH (E) , and CH (D)) from the reaction of substituted acetophenone with 2- pyridine carboxyaldehyde by using Claisen- Schmidt condensation method and catalyze the reaction by KOH pellets. After purification process, the yield was good to characterize them by using chemical structure analysis (FTIR, C13NMR, Mass spectrum), which approved their structures. Cytotoxicity evaluation was with 100 µM for each concentration compound against Human Breast Cancer MDA-MB231 Cells and we identified two pyridine chalcone derivatives showed a moderate action. The results of toxicity evaluation pave a forward step to develop new anticancer agents as from pyridine chalcones as a lead structure.

Pre-Treatment Of Erythrocytes With Garlic Or Tea Tree Oil Promotes Oxidation Of The Peroxiredoxin 2 Protein And Makes The Cells Less Susceptible To Infection By Plasmodium Falciparum


Journal of Basrah Researches (Sciences), Volume 45, Issue 1, Pages 45-56

      Plasmodium falciparum, the causal organism of the most deadly form of human malaria, lacks catalase and glutathione peroxidase enzymes and thus is highly dependent on peroxiredoxin (Prx) enzymes for its defence against oxidative stress. In addition to its own five Prx enzymes, P. falciparum also uses the human Prx2 protein which it imports from the host erythrocyte. Here we have investigated the effects of pre-treatment of uninfected erythrocytes with increasing concentrations of garlic or tea tree oil on the redox/oligomerization state of the Prx2 protein and on the P. falciparum parasitemia in the erythrocytes. Both oils were shown to be able to disrupt the Prx2 redox state in pre-treated uninfected erythrocytes by promoting oxidised dimer formation. Garlic oil was a more potent promotor of the oxidation/inactivation of the Prx2 protein than tea tree oil. The results also showed that both oils promoted oxidation/inactivation of the Prx2 protein at the 2nd generation ring stage and also appeared to promote oxidation of other sulfhydryl group-containing proteins. Additionally, pre-treatment of uninfected erythrocytes with the test oils made the erythrocytes less susceptible to infection by P. falciparum at the 2nd generation ring stage (new infections). Garlic oil was more effective than tea tree oil in this respect. Thus, oxidation of the Prx2 protein might be involved in decreasing the susceptibility of pre-treated uninfected erythrocytes to infection by P. falciparum. These results suggest that garlic and tea tree oils could be used as antimalarial drugs.

The mammalian typical 2-Cys peroxiredoxin (Prx) proteins have emerged as important sensors and transducers in the cellular response to oxidative stress. Plant natural products have been shown to have both pro- and anti-oxidant effects but their exact mechanisms of action are not fully understood. Here we show that selected compounds from garlic and tea tree oils promote either oxidised dimer formation or hyperoxidised monomer formation in the typical 2-Cys Prx proteins. Diallyl disulphide (DADS) and diallyl trisulphide (DATS) were the main constituents of garlic oil and showed similar effects to their parent oil but DATS was more effective than DADS that indicating to the importance of the number of sulphur atoms. Tea tree oil was a less potent promotor of the oxidation of the Prx proteins than garlic oil. In contrast, terpinen-4-ol, the major constituent of tea tree oil, was a very effective promotor of the oxidation of the Prx proteins. We show that the results could partly, but not entirely, be explained by differences in the effects of the tested compounds on the activity of thioredoxin reductase (TrxR), the enzyme required for the regeneration of the reduced monomer form of the Prx proteins from their oxidised dimer form. The results are discussed in terms of the involvement of the typical 2-Cys Prx proteins in the cellular response oxidative stress.

Muter M.A.; A.Z Al-Mayahi; W.M Al-Mosawi

Journal of Basrah Researches (Sciences), Volume 45, Issue 1, Pages 86-101

      Shatt Al-Arab River is one of the most important Iraqi waterways. It has suffered from different types of natural and man-made variations, specifically the past 40 years  such as dramatic declination in water discharges due to recent hydraulic constructions. These changes  affected the bottom, sub bottom, and geomorphologic features of the river bed. To images these changes, a marine geophysical survey represented by high-resolution Sub–Bottom Profiler  was carried out to describe the morphology, structure, and sub-bottom layers of Shatt Al-Arab river. Four sub-bottom transverse profilers were carried out by Strata Box transducers, 10 kHz at Al-Sendebad Island, Al-Ashaar, Um Al-Rasas Island and Sihan meandering areas.
      The results of the sub-bottom profilers showed that the used technique is an essential tool to map sub-marine geological features and locate the buried structures in the river bottom. Specifically,  at Al-Sendebad Island,  there is a depositional process have increased  about 5 m, the recorded depth was  18 m, but it was about  (24-22 m) in previous studies. In Al-Ashaar site section,  many types of sub bottom layers formed by recent and old deposits were correlated with well-log data, the bearing strata is located at 20 m under the bottom of the river. At Um Al-Resas Island,  there is no indication of tectonic activity which may form the Island. The highest depth of the river bottom  recorded at Sihan meandering is about 22 m. These changes may due to  the changes in the hydrological and depositional systems of the river. At Sihan meandering, there are  many prominent features like large depths, river meander, buried channels of ancient streams and a possible trace of fault which may be an indication of neotectonic activity.

Journal of Basrah Researches (Sciences), Volume 45, Issue 1, Pages 102-116

    Many studies have been carried out to find the best method for classification of remote sensing data. Traditional methods depend only on pixel value without using the spatial and geometric information of object which is consider an important source to classify the satellite imagery. This study compared between pixel-based and object-based classification algorithms using Sentinel-2 imagery. As for object-based image analysis, the image was segmented in to homogeneous groups using appropriate variables such as scale, shape, size and probability. Classification based on segments was done by a nearest neighbor classifier, while the classification based on pixel value was done by manual digitizing by using the principles of visual interpretation. For accuracy assessment, an error matrix was used to assess the classification between two types of classification. The producer’s accuracy for gully class using object-based image analysis was 90.7% while the user’s accuracy for gully using pixel classification was 84.8%. These classification techniques were subjected to accuracy assessment and the overall accuracy was 89.2% and 0.78 for Kappa coefficient. The results of classification and its accuracy assessment show that the object-based image analysis approach gave more accurate results.

Journal of Basrah Researches (Sciences), Volume 39, Issue 2, Pages 49-56

The objective of this paper is to study the stability of charged isentropic superdense star models. A limitation of the density variation for different models guided by a specific choice of a measure of departure from physical geometry of the physical space to ensure the physical acceptability have been obtained and analyzed. The solution so obtained has large density and pressure at the center, however the energy conditions are seen to be satisfied throughout certain spherical regions. In addition to that, these models are seen to satisfy various physical conditions. In our present paper the stability of charged superdense star has been found. Runge-Kutta method has been implemented for the superdense models which it has been found to satisfy various physical conditions.

Maytham A. Shahed; Emad S. Jabbe

Journal of Basrah Researches (Sciences), Volume 34, Issue 1, Pages 64-72

This paper presents new techniques for noise reduction depending on filters. The two proposed filters are to simulate and improve the effects of two kinds of smoothing filters: Mean and Median filters. These two filters are of amplitude and statistic kinds but they are vibrated between the linear and nonlinear kinds.The first proposed filter takes the average of mean and median filters for each pixel in the image as a new pixel in the filtered image. While the second filter takes the average of the W median intensity values in the mask (H×W) for each pixel in the image as a new pixel in the filtered image.Simulations show that the proposed filters work well in suppressing two different kinds of noise: Poisson and Gaussian from both images grayscale and RGB while preserving image details.

T.M.Muhsin and K.J.Humadi; R.R.Hateet

Journal of Basrah Researches (Sciences), Volume 40, Issue 1, Pages 94-101

An endophytic fungus isolated from root of tomato plant displayed considerable antibacterial activity. The fungus was identified as Fusariumsolanibased on morphological characterization. Fungal extraction was carried out by ethyl acetate solvent. The metabolite showed activity against both bacterial testes. Bioactivity of fungal extract against E. coli(ATCC25922) and S. aureus (NCTC6571)by using a disc diffusion technique was examined. The inhibition zones exhibited by fungal extract were 28 mm diam of E. coli and 45 mm diam of S. aureus . MIC test revealed that the extract of Fusariumsolaniexhibited a minimal inhibition values (12.5 and 6.25 ug/L) against E. coli and S. aureus, respectively. A verification of non-toxicity of the fungal extract against human blood revealed a negative test. The chemical analysis of the fungal crude extract showed that extract of Fusariumsolani contains Tannins group and phenol compounds, absent amino acid and flavenoide.The metabolite produced by the endophytic fungus could be an alternative source of antimicrobial agents against clinical pathogens.
