Ferrite nanoparticles with the spinel-type structures Cu1-xZnxFe2O4 (where; x= 0.0 to 1.0) were synthesized using auto-combustion sol-gel method. Auto-combustion reaction temperature was determined by thermo-gravimetric analysis (TG), and found it is in the range of (200-220)°C. Fourier transform infrared spectra (FTIR) showed two absorption bands (v1 and v2) that are attributed to the stretching vibration of tetrahedral and octahedral sites in the spinel structure. X-ray diffraction was used to study the structural properties of the above investigated ferrites. Powder-forming particle sizes were characterized and calculated by XRD pattern peak (311) and scanning electron microscopy (SEM). As a result the average particle size found to be in the range of 15-30 nm. The lattice parameter (a) was calculated for each composition and it is in the range of (8.2733 to 8.3720 A°). A significant decrease in density and subsequent increase in porosity were observed with increasing Zn content in Cu-Zn ferrite.

The aim of the present work is to use (ARIMA) model (Auto Regressive Integrated Moving Average) in the treatment of the cuts in time series of evaporation data. Time series of monthly average evaporation data (1971-1999) has implemented in our study .It has been observed that the above mentioned model can be used and operated in the treatment of cuts in particular the increased of pre cuts data as when the input data (348) month the value of (MAE,RMSE, R2) is (0.0978, 0.140574, 0.997544) respectively and hence decrease the accuracy with decrease of data. It is also noted that if the input (120) month (MAE,RMSE, R2) is (0.3055, 1.079692, 0.889669) respectively.

الخلاصة

Two new surfactants were synthesized from renewable materials via click chemistry. The starting materials are carbohydrates (e.g. methyl glycoside) and fatty acid derivatives based on both saturated and unsaturated fatty acids with a total chain length of C12 and C18. Target applications of these surfactants focus on the stabilization or emulsions, in particular water-in-oil emulsions. The synthetic scheme applied a multi-step methodology, including activation, functionalization and finally coupling with fatty acids derivatives by using click chemistry technique. Surfactants were identified and their purity confirmed by NMR type 1H and 13C in addition to high resolution mass spectroscopy. Physical properties were studied by optical polarizing microscopy (OPM), differential scanning calorimetry (DSC) and surface tension measurements. Lyotropic phases were investigated by contact penetration with water under the OPM, while surface tension measurements used the DuNouy ring approach. The latter enables the determination of critical micelle concentrations

Three transition metal-Phthalocyanines are investigated (metals= Co,Ni,Cu) using semi-empirical methods. PM3 and ZINDO/S have been used because they maintain transition metal parameters. PM3 has been used for geometrical optimizations, while ZINDO/S has been used for single point calculations to predict the electronic energy states. The last one is showed better results for single point calculations while the former was better for geometrical optimizations. The symmetries reached were D4hforCuPc while it was D2h for CoPc and NiPc. The obtained bond lengths compared with reported experimental and more sophisticated theoretical methods values. The results were in good agreement. The obtained molecular orbital energies were of reasonable accuracies. Nevertheless, these methods are much faster when compared with expensive Ab-initio methods that need high performance expensive computers. Three dimensional plotting of electronic charge distributions and electrostatic potential isosurfaces have been plotted as well.

This research was carried out to study the effect of Agaricus bisporous mushroom on reducing the sugar and cholesterol in blood and determine its activity on improving the bactericidal power of serum collected from a group of healthy volunteers. So, about fifty healthy volunteers from both sexes ranging in age from (20-30 years) and of a weight between (65-100 kg) were included in this study. Results of nourishing (150g) of Agaricus bisporus mushroom as a diet to about (40) healthy volunteers from both sexes twice a week for two months did not show any change in body weight mass (BW) compared with the controls after two months of mushroom administration. However, a significant difference (P <0.05) in serum glucose and cholesterol concentrations in both (male and female volunteers of the study) was detected. In addition, the effect of Agaricus bisporus mushroom administration on the bactericidal activity of normal serum was also studied and a significant difference (P <0.05) in the bacterial colony counts especially in the colony counts of the bacterium Staphylococcus aureus was recorded. Moreover, the ethanolic extract of the Agaricus bisporous mushroom showed a significant (P <0.05) antibacterial activity against Staphylococcus aureus strains only.

The present study was conducted for the period from 1st/ August/ 2010 to 30th/ November/2011 in Baquba city.The study aimed to explore the diagnostic capability of two laboratory techniques namely; rapid latex agglutination test, enzyme-linked immunosorbant assay for the detection of rotavirus in stool specimens of human. The study included 120 patients with acute diarrhea, 70 were male and 50 were female. The age range was from two months to 5 years.Detection of rotavirus in stool specimens was done by direct agglutination test (DAT) and Enzyme-liked immunosorbant assay (ELISA). The results of present study showed that the overall infection rate by rotavirus among patients with acute diarrhea by DAT and ELISA tests was 70% and 93.33%. The sensitivity and specificity of DAT and ELISA tests in detecting of RV in human stool specimens were 75.56% and 66.67% for the DAT test, whereas, 91.3% and 66.67% for ELISA test. The study concluded that rotavirus was detected in high rates among children less than 5 years old with acute diarrhea in Baquba city, particularly those less than 2 year old. Furthermore, the detection rate by ELISA was higher than by DAT test, suggesting that ELISA is the most appropriate method with excellent sensitivity and specificity for detection of RV in stool specimens in a setting like that in Baquba city.

We have studied the effect of gamma radiation on the absorption spectra of Poly methyl methacylatc doped Blue methyl (PMMA:Blue methyl) films deposited for thickness (25 ± 1 µm) by using solvent casting method. Transmittance and Absorptance spectra have been recorded in order to determine reflectivity. These films show that the energy band gap has decreased from about (2.16eV) before irradation to about (1.97 eV) and (1.21 eV) after irradiation . The optical constants such as refractive index , extinction coefficient , real and imaginary parts of dielectric constant have also been studied , It was seen that all the parameters under investigation were affected by gamma irradiation.

Discriminant analysis is use in situations where the clusters are known a priori. The aim of discriminant analysis is to classify an observation, into these known groups. For instance, in credit scoring, a bank knows from past experience that there are good customers(Who repay their loan without any problems) and bad customers(Who have had difficulties repaying their loans). When a new customer asks for a loan, the bank has to decide whether or not to give the loan. The information of the bank is given in two data sets: multivariate observations on the two categories of customers(including age, salary, marital status, the amount of the loan and the like)
