Furthermore, no significant differences were noticed between the infection and the kind of sex . Also it appeared that the infection rate was high among those sent for general stool examination in July 2002 and October and December in 2003 and the rate was low in January 2002 and April 2003.

The goal of this study was to apply the concept of passive microwave remote sensing to find the data set of microwave brightness temperatures of the dry soil surface as a function of actual salinity factors that influence the dielectric properties of the soil.



From the agricultural point of view, salinity factor refers to the state of accumulation of the soluble salts in the soil. In many area, this factor limiting plant growth (such as sodium chloride).
The measurements of the dielectric permittivity were conducted using shorted-circuited-waveguide technique at L-and C-band microwave frequencies (i.e. 1.4GHz and 5GHz, respectively). The dielectric properties of the salted soil samples were investigated at a thermodynamic temperature of 20.4 c .
The results show that the frequency of 1.4GHz (L-band) is more effective frequency for study of the penetration depth of the soil surface. Also the vertical polarized microwave signals is preferred to study the variation of the emission characteristics of the dry soil with respect to the salinity by using the microwave radiometric remote sensing techniques especially at low microwave frequency.

This paper describe the preparation of new ligand bis-(n-butylthio)ethane (L) from the reaction of dibromoethane and potassium-n-butylthiolate. Mono nuclear complexes were obtained by direct reaction of the above ligand with CoCl2.6H2O,NiCl2.6H2O and CuCl2.4H2O in 1:1 metal to ligand , while the dinuclear complexes were obtained from the reaction with SbCl3 or Bi(NO3)3 in 2:2 metal to ligand. Trinuclear complexes of general formula [M´2M(L)2X6]Cl2 were obtained from the reaction of [M´2(L)2X6], M´= Sb+3 or Bi+3 with metal chloride in 1:1 molar ratio, M=Co+2, Ni+2 or Cu+2.
The prepared complexes were characterized by metal analysis, IR,U.V-visible spectroscopy, conductivity and magnetic measurements.

his study indicates the biological activity of Allium. The activity extracts including alcoholic and ethanolic volatile oil was studied against eight bacterial species: Salmonella typhi, Shigella flexneri, Escherichia coli, Proteus mirabilis, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis.

In the present study, antibacterial properties of three different extracts from Glycine max L. seeds were screened against four types of Gram-positive and negative bacteria Staphylococcus aureus, Bacillus cereus, Klebsiella pneumoniae and Pseudomonas aeruginosa using agar-well diffusion method and comparing with standard antibiotics Chloramphenicol, Cephalexin, Tetracycline and Gentamycin. The ethanol extract demonstrated good inhibitory effects against most tested bacteria using the extract concentration 200mg/cm3 compared with chloroform and petroleum ether extracts which gave clear inhibitory effect against Ps. aeruginosa using the same extract concentration the study also revealed the complete resistance of B. cereus towards chloroform and petroleum ether extracts but was inhibited using all ethanol extract concentrations and the proportion between inhibitory effect and extract concentration was direct.

The present study aimed to investigate the effects of passive smoking to induce embryonic malformations and eye lesions during development of the swiss albino mice Mus musculus. The pregnant females were exposed to cigrate smoking at variable time periods (1.5,2,2.5,3) hour daily, which started at the 7th day of pregnancy until delivery of neonate. The results revealed no pregnant period prolongation in contrast to control group. The results showed at the exposure of the mice for (1.5)hrs daily for two weeks of passive smoking there were no morphological malformatios, but some histological features appeared such as scleral pyknotic, lens swelling. At (2)hrs of exposure daily, there were (15%) of the seen embryos showed malformations; one of these morphological defect was congested. But the histopathological features were central retinal hyperplasia, and corneal pyknosis. At(2.5)hrs exposure to passive smoking, (17%) of embryos showed limb deformity and some histopathological malformations such as lens dentation and apoptosis of some neural retinal cells. At(3)hrs exposure daily, (25%) of embryos suffered from morphological and histological malformations represented in face deformity, necrosis of inner plexiform layer and ganglion cells pyknosis of the retina, compared with the control group

This paper tackles the attitude of nursing staff towards the use of computers in hospitals especially in matters of documenting patients' records, and surgeries by Microsoft Access program which store data and other relevant information as information-bases set in tables and organized formulae, then displaying them in a way that facilitates access to data, storage of data and retrieve of data. Besides, this paper has designed a questionnaire consisting of question items regarding the attitudes of nurses made up of a sample of secondary school, health institutes and university graduates who currently practise or work at four hospitals in Nineveh district.
Their answers have been statistically analyzed by Microsoft Excel according to their qualifications.
Results confirmed hypothesis regarding the positive response to the use of computers since they reduce the paper work bulk, let alone the usefulness of computers as a clinical and administrative tool that is highly efficient in organizing nursing processes .However, the secondary school graduates do not find computers useful for their work.

Gambusia affinis fishes were exposed to 2,4 and 8 mg Cd/L of water for 8 days and for 2,4, and 8 days to 10 mg Cd/L of water. Gills were used to investigate the effect of cadmium on the activity of four enzymes measured by calorimetric methods.

There were no clear changes in the activity of Alkaline phosphatase at different concentrations but the activity increased at different periods of exposure to cadmium.

There was no change in the activity of aspartate aminotransferase (AST) at different concentrations and periods of exposure. Alanine aminotransferase (ALT) activity increased at the concentrations 2 and 8 mg Cd/L, but the activity increased after the first period and decreased gradually at other periods of exposure to the metal.

Some parameters and their effects on CO2 laser output were studied in this research. This has been done through studying the effect of gases mixture pressure inside the electrical discharge tube and effect of electrical discharge current. Calculating (E/N) through molecular population using the optimum power parameters of the molecular laser CO2, was done. The theoretical value of output power and this value were compared with the practical value. It was found that the optimum operating conditions for the system were (35 mbar) as an operating pressure and (25 mA) as discharge current, where the velocity of the cooling water flow rate was . System efficiency in the optimum operating cases of CW CO2 laser reached (1.7%) and system output power was (0.765 Watts). The best value of the factor (E/N) of the system has been determined and found to be (3.42  10–16 V.cm2) which is near the international calculated standard value of CO2 laser systems

t may be possible to find the Wiener polynomial with respect to a generalized distance of a compound graph constructed from two graphs having some kind of regularity. In this paper, we obtain the Wiener polynomials for a generalized distance of compound graphs constructed from a complete graph with some other special graph, such as a complete bipartite graph, a star, and a wheel, using binary operations defined by Gutman [4]. The Wiener index with respect to such generalized distance for each such compound graph is also obtaine

The aim of this paper is to establish a new method for calculating generalized curvature and generalized torsion. This method depends on at least three points infinitely close to the considered point. The established method is characterize from other methods by using only dot and cross product of vectors combined from this points, without any parameter that interacts in the defined curve by using some concepts of nonstandard analysis given by Robinson A. and axiomatized by Nelson E.

This research tackles the analysis of spatial covariance structure for two different spatial data sets which involve the crome ore and copper ore respectively, where crome ore lies in a regular lattice and the copper ore lies in an irregular lattice. The fitted Varigoram function to the crome ore is appeared to be the spherical model while the fitted one to the copper ore is appeared to be the De Wijsian model, the De Wijsian model is characterized to have infinite variance and this can be seen in figures that are obtain in this work. Finally, the elementary Krigins is carried to both ores and the results are encouraging
