Abstract

Direct FIA methods for estimation of Naringenin (NG) in different samples were proposed. These methods are based on diazotization coupling reactions of two reagents: method (A) p-chloroaniline (PCA) and method (B) procaine hydrochloride (PRH) with NG in basic medium. Yellow dyes with maximum absorption at 416 and 415 nm were formed respectively. Calibration curves were constructed over different NG concentrations, linearity was from 1- 70 and 1- 40 µgmL-1 with detection limits of 0.55 and 0.24 µgmL-1 for (A) and (B) respectively. All analytical variables involved in the FIA procedure were evaluated and optimized. The established methods were successfully applied for the determination of NG in its supplements and urine samples.

Abstract

Tropical illnesses caused by parasites proceed to cause socioeconomic devastation that reverberate worldwide protozoan parasites, like Leishmania. This parasite has an enormous public health problem in many countries. There is a growing requisite for new control methods for many of these illnesses due to the increasing drug resistance showed by the parasites and problems with drug poisonousness. In this study, fifty-five patients (burns and wounds) were collected from patients from Al-Yarmouk Hospital and Teaching Baghdad Hospital during the period from November, 2015 to January, 2016. Cultural and morphological characteristic examination, biochemical tests were conducted and confirmed the diagnosis by antibiotics sensitivity test and Vitek-2 system. The results identified thirty-three Staphylococcus aureus and thirty Pseudomonas aeruginosa from skin burn and wounds. Vitek 2 system gave confirmation of positive results for both strains with a probability 98-99%. The S. aureus isolate (S3) and P. aeruginosa (P 5) was chosen among bacterial isolates as a good producer for crude both bacteriocins according to their widest inhibition zone by well diffusion assay WDA. Two steps method extraction were used for bacteriocin purification, first via ammonium sulphate at 70% and next step by Sephadex G-50 gel filtration chromatography. The two new drugs staphylococcin and pyocin at different concentrations was used for the treatment of L. tropica and L. donvani. All concentration of Staphylococcin showed no inhibitory activity on promastigotes of L. tropica and L. donvani. While the concentration of 32.5 µgmL-1 of pyocin showed the maximum cytotoxic effect on promastigotes of L. tropica and L. donovani, where the inhibition rate (IR%) were 87.1% and 87.9% respectively. As part of the research objectives is the discovery of new treatments against leishmaniasis also benefit from improved models.

Abstract

Microbiological quality (total plate count, yeast and molds, coliform, and E. coli) of wheat cultivated in seven provinces of Iraqi were determined and compared to Standard Quality of Iraq (IQS) and to the standardization of Food and Drug Administration (FDA). The samples were collected from fields, and some samples taken from near of a street (reachable by people) and far of a street as well as rural fields. The regulation has two limits, which are good and acceptable limits, and the samples within the acceptable limit should be two samples of five. The results showed that all analyzed samples were within the acceptable limit that approved by IQS and FDA. There was one field exceed IQS regulation and there were several fields exceed the FDA regulations related to the number of samples within the good limit. The main reason for exceeding was total plate count (APC) followed by yeast and molds. Enhancing the microbiological quality of wheat cultivated in Iraq should be truly considered to be within IQS and FDA regulations.

Abstract

Investigation of geotechnical vulnerability (liquefaction) and Zonation of the southern region of the Caspian Sea is my most important aim in terms of destructive earthquakes hazard potential. Past geologic events on the south coast of Caspian Sea indicates that destructive earthquakes lead to the death of numbers in this area. Remained evidence of seismic events happening indicates extensive landslides, liquefaction and soil subsidence in the residential and even natural area. Therefore, in this study determination of geotechnical vulnerability (liquefaction) intensity in southern coast of Caspian Sea against natural forces resulting from earthquakes and coastal construction via geographical information system environment (GIS) is considered as the research most important purposes. Therefore, seismic and consequence natural phenomena hazards potential are high in Southern Caspian region. The results of this study indicate that in terms of performance of instability factors such as: storm waves, sedimentary material subsidence and slide, coastal sand liquefaction, the southern part of the Caspian Sea coastal areas and sea bed sections are so vulnerable. So my aim of this study at first is to illustrate the variety of methodologies currently in use for preparation of seismic hazard maps and to evaluate basic principles of zonation for different purposes and at different scales. Guidelines and recommendations for seismic microzonation should be incorporated into seismic regulations. Indeed, by its results susceptible of risk area are determined and high risks areas are identified in terms of occurrence of geotechnical processes such as liquefaction by this recommendations many researchers apply this methods for seismic-geotechnical hazard zonation in three grade.

Abstract

Reservoir unit classifications can be used in reservoir characterization of carbonate reservoirs where there is variability in the distribution of petrophysical properties. This requires the integration of geological and petrophysical data at different scales. In this study, cores and thin sections from Yamama Formation (Lower Cretaceous) at Gharaf oilfield, southern Iraq, were studiedto identify reservoir units. Ninereservoir units (units Y1 to Y9) were identified based on petrophysical evaluation by using interactive Petrophysics program (IP) software and depositional environments and related microfacies.The unit Y2 have the highest reservoir quality, which consists of grain-supported facies(packstone and grainstone) characterized by high values of effective porosity and oil volume.The second important reservoir unit is unit Y7 where oil exists in wells Ga-1, Ga-4, and Ga-5. By contrast, the unit Y6 is identified with no observable reservoir quality due to low porosity of mudstone microfacies. The computer processes interpretation (CPI) results show that unit Y1 has poor petrophysical properties except in wells Ga-3 and Ga-4 where reservoir properties are enhanced by fractures. Other units are characterized by different degrees of reservoir quality, and they are differentiated in terms of effective porosity, water saturation, clay volume, and facies types.

Abstract

In this paper a Г-ring M is presented. We will study the concept of orthogonal generalized symmetric higher bi-derivations on Г-ring. We prove that if M is a 2-torsion free semiprime Г-ring , D_n and G_n are orthogonal generalized symmetric higher bi-derivations associated with symmetric higher bi-derivations d_n and g_n respectively for all n ϵN. Then the following relations are hold for all x,y,zϵM,αϵГ and nϵN: (i) D_n (x,y)αG_n (y,z)=G_n (x,y)αD_n (y,z) =(0) hence D_n (x,y)α〖 G〗_n (y,z)+ G_n (x,y)αD_n (y,z)=0 . (ii) d_n and G_n are orthogonal and d_n (x,y)αG_n (y,z)=G_n (x,y)αd_n (y,z)=(0) . (iii) g_n and D_nare orthogonal and g_n (x,y)α D_n (y,z)=D_n (x,y)αg_n (y,z)=(0) . 〖(iv) d〗_n and g_n are orthogonal symmetric higher bi-derivations . (v) d_n G_n=G_n d_n=0 and g_n D_n=D_n g_n=0 .

Abstract

Lately, a growing interest has been emerging in age estimation from face images because of the wide range of potential implementations in law enforcement, security control, and human computer interactions. Nevertheless, in spite of the advances in age estimation, it is still a challenging issue. This is due to the fact that face aging process is not only set by distinct elements, such as genetic factors, but by extrinsic factors, such as lifestyle, expressions, and environment as well. This paper applied machine learning technique to intelligent age estimation from facial images using J48 classifier on FG_NET dataset. The proposed work consists of three phases; the first phase is image preprocessing which include five stages: gray scale image, noise removable, face detection, image size normalization and clipping process. The second phase is a data mining process which includes three stages: feature extraction, feature selection and classification using j48 classifier. The third phase includes two stages, estimation and evaluation. FG-NET dataset is used which is divided into three classes; first class represents (3-7), (26-30) ages and this class represents the ages from 3 to 7 years and from 26 to 30 years because this class have four attributes from any one of this images, second class represents (8-25) ages and this class represents the ages from 8 to 25 years because this class have five attributes from any one of this images, last class represents (31-50) ages and have nine attributes from any one of this images. The Experimental results illustrate that the proposed system can give results with high precision and low time complexity. The practical evaluation of the proposed system gives accuracy up to 89.13 % with time taken of 0.023.

Abstract

Meerkat Clan Algorithm (MCA) that is a swarm intelligence algorithm resulting from watchful observation of the Meerkat (Suricata suricatta) in the Kalahari Desert in southern Africa. Meerkat has some behaviour. Sentry, foraging, and baby-sitter are the behaviour used to build this algorithm through dividing the solution sets into two sets, all the operations are performed on the foraging set. The sentry presents the best solution. The Flexible Job Shop Scheduling Problem (FJSSP) is vital in the two fields of generation administration and combinatorial advancement. In any case, it is very hard to accomplish an ideal answer for this problem with customary streamlining approaches attributable to the high computational unpredictability. Most scheduling problem are mind boggling combinatorial problem and exceptionally hard to settle. The experimental result that compare with Cuckoo Search algorithm, Artificial Fish Search Algorithm, and Camel Herd Algorithm show that the MCA can find optimal solution because it provides a good strategy.

Abstract

In this paper, the method of estimating the variation of Zenith Path Delay (ZPD) estimation method will be illustrate and evaluate using Real Time Kinematic Differential Global Positioning System (RTK-DGPS). The GPS provides a relative method to remotely sense atmospheric water vapor in any weather condition. The GPS signal delay in the atmosphere can be expressed as ZPD. In order to evaluate the results, four points had been chosen in the university of Baghdad campus to be rover ones, with a fixed Base point. For each rover position a 155 day of coordinates measurements was collected to overcome the results. Many models and mathematic calculations were used to extract the ZPD using the Matlab environment. The result shows that the ZPD values in mm depend on the water vapor intensity in the atmosphere and the mean temperatures. Also, the mean temperature model can be generated to calculate the Water Vapor Intensity( WVI( for 20 km highest.
