Abstract

The parasite Entamoeba histolytica has been isolated and cultivated in vitro via using Locke-egg medium (LEM) and Liver infusion agar medium (LIAM) . After that, the effect of some types of sera (sheep, bovine and human) on the growth and activity of the parasite in the two culture media was investigated. The reproduction rate has been significantly increased when the sera of sheep and bovine were supplemented to LEM medium to reach 105.5 and 142.6%, respectively. Human blood group (A) serum was also effective, but with a less degree, and such effect was a medium-dependent (LEM: 49.1%; LIAM: 26.9%).

Abstract

Bacterial contamination of AL-Habania reservoir was studied during the period from February 2005 to January 2006; samples were collected from four stations (AL-Warrar, AL-Theban regulator, middle of the reservoir and the fourth was towards AL-Razzaza reservoir). Coliform bacteria, faecal Coliforms, Streptococci, and faecal Streptococci were used as parameters of bacterial contamination in waters through calculating the most probable number. Highest count of Coliform bacteria (1500 cell/100ml) was recorded at AL-Razaza during August, and the lowest count was less than (300 cell/100ml) in the rest of the collection stations for all months. Fecal Coliform bacteria ranged between less than 300 cells/100ml in all stations for all months to 700 cell/100ml in AL-Warrar, AL-Razaza and in the middle of the reservoir stations during August. Streptococci bacteria count ranged between less than 300 cell/100ml to 700 cell/100ml as a highest record in AL-Razaza station during August for both. The ratio between fecal coliforms and fecal streptococci (FC: FS) was detected to determined the origin of the pollution in the reservoir depending on Geldrich statistical law in this research, the ratio ranged between (1) to (2.3).

Abstract

This research deals with the study of top soil electrical conductive regions located within Baghdad City. The research included measuring the dissolved soil material extraction Electrical Conductivity (EC) with an aqueous solution for the top (0-30 cm) soil layer of the study area. As the electrical conductivity values increase by increasing the amount of dissolved salts in principle, we can consider that the aim of this research is to predict the amount and distribution of (soil contamination with salts) which is represented by the (Salt Index), this factor calculated for each soil representative sample taken from the region with a depth of (30 cm). Laboratory (EC) test values measured by the use of solutions (EC) digital meter for the extract of the dissolved soils with a distilled de-ionized water using the ratio of (2:1) .The distributed (EC) values for the field representative soil samples used lately to plot a contour equi-electrical conductivity map and EC soil fluctuation profiles, in which reflected the top soil layer salinity distribution according to Tigris river position in the study area , also it reflects the increase and decrease of this layer salinity in a relation to the river position. This study concluded that the highest soil salinity concentrations located at the southern east part of the study area, while the lowest concentrations are located on the intersection areas with Tigris river stream, other areas in which are few kilometers far from the river stream showed moderate salinity concentrations. These results could be helpful for Environmental and agricultural benefits, through identifying the salty soil pollution region and look for ways of treatment.

Abstract

Two dimensional power spectral analysis techniques have been applied on gravity data for AR Rub' Al Khali region to estimate the depths to basement structures. The studied region is located in NE Yemen where little information about the deep geology is available. The estimated depth values are ranging between 3.5 to 9.5Km. The western and eastern parts have the deepest values while the middle part has an elevated basement features. The distribution style of deep and shallow structural features reflect the orientation of graben and horst structures with lateral displacements. The graben structures with great depths and with large areal extent highlight the importance of this region for possible oil accumulation, since most Yemen oil fields are located within graben structures. The deduced shapes, trends, and depths of these structures and their three dimensional representation are so useful and encourage the future oil exploration in this part of Yemen territory.

Abstract

The modified Bohm diffusion equation is studied in the inner region of plasma column in Q-machine. The instability factor (C-factor) and modified Bohm diffusion efficient are calculated in that region of plasma column. The results are compared with those calculated according to Bohm equation and with experimental results. The comparison with experimental shows a better agreement when the instability factor (c) is taken into the account. The diffusion coefficient and the instability factor are calculated for strong and weak turbulence case. The results of both cases are examined with Bohm diffusion equation as well as with experimental results. A good fitting has been obtained for strong turbulence results with experimental results. Whereas, an approximate agreement are found between weak turbulence results in the region near from a center and edge of plasma.

Abstract

The vibration frequencies and infrared absorption intensities for the fluoranthene molecule (C16H10) and their positive and negative radical ions have been calculated using ab initio method according to the density functional theory (DFT) at the B3LYP / 6-311G basis set, in addition to PM3 semi-empirical quantum chemical method. Although, the importance of this molecule due to their presence in interstellar space and their environmental contaminating properties, the literatures miss to a complete classification for (3N-6) vibration modes and the vibration frequencies and infrared absorption intensities calculations for the negative radical ion. For these reasons our calculation and classification considered to be assignment. All calculated vibration frequencies rearrangement as the Hertzberg convention, then classified symmetrically and assigned by valence for (3N-6) modes depending on graphical pictures obtained by using Hyperchem program. Generally, the calculated vibration frequencies values showed a good agreement and compatible with values measured experimentally and those calculated by other theoretical methods.

Abstract

One of most the important compounds which have active hydrogen (substrate) is the thiols which used in a wide field in preparation of Mannich bases . A large number of Mannich bases have been prepared as a biologically active compound (pharmaceutical, pesticides, bactericidal, fungicidal and tuberculostatic) and in order to correlate their structure and reactivity with their pharmacological activity such as . It has been reported that the reaction is easily proceeded by using primary and secondary amine beside formaldehyde. But when we tried the reaction of thiols as substrate and formaldehyde and succinimide instead of amine, the reaction did not proceed to give Mannich base but product were methylenene – bis – sulfide . Mannich base can go farther reaction such as (addition, substitution, cleavge, polymerization, hydrogenation) to produce numerous numberbof compound so we tried to hydrogenation tetrazole derivative which gave different product which depened on type of hydrogen on reagent. Reduction of 2 – ethyl benzoyle – phenyl tetrazole which performed with hydrogen gas in methanol solution in presence palladium on carbon as catalyst, the tow products were separated by column chromatography. Reduction of 2 – methyl – 2 (2 – cycloheptane) – 5- phenyl tetrazole. The methanolic solution the ketone was refluxed with equimolar amount of potassium borohydride and the product is isolated and purified to give. and identified by C.H.N analysis and NMR spectra.

Abstract

The widespread of internet allover the world, in addition to the increasing of the huge number of users that they exchanged important information over it highlights the need for a new methods to protect these important information from intruders' corruption or modification. This paper suggests a new method that ensures that the texts of a given document cannot be modified by the intruders. This method mainly consists of mixture of three steps. The first step which barrows some concepts of "Quran" security system to detect some type of change(s) occur in a given text. Where a key of each paragraph in the text is extracted from a group of letters in that paragraph which occur as multiply of a given prime number. This step cannot detect the changes in the reordering letters or words of the paragraph and text without changing the letters themselves. So, the next step uses one of the error detection methods which is named Hamming Codes to find out the locations of the change in the received text. After that; at the third step, RSA as a primary encryption method has been used to encrypt the keys extracted to the first step and second step in order to prevent the intruders to break down the security of the method.

Abstract

In the current Windows version (Vista), as in all previous versions, creating a user account without setting a password is possible. For a personal PC this might be without too much risk, although it is not recommended, even by Microsoft itself. However, for business computers it is necessary to restrict access to the computers, starting with defining a different password for every user account. For the earlier versions of Windows, a lot of resources can be found giving advice how to construct passwords of user accounts. In some extent they contain remarks concerning the suitability of their solution for Windows Vista. But all these resources are not very precise about what kind of passwords the user must use. To assess the protection of passwords, it is very useful to know how effective the widely available applications for cracking passwords. This research analyzes, in which way an attacker is able to obtain the password of a Windows Vista PC. During this research the physical access to the PC is needed. This research shows that password consists of 8 characters with small letter characters and numbers can easily be cracked if it has know usual combinations. Whereas a Dictionary Attack will probably not find unusual combinations. Adding captel letter characters will make the process harder as there are several more combinations, so it will take longer time but is still feasible. Taking into account special characters it will probably take too long time and even most Dictionary Attacks will fail. For rainbow tables the size of the table has to be considered. If it is not too big, even these small passwords cannot be cracked. For longer passwords probably the simplest ones, small letter characters and numbers, can be cracked only. In this case brute force takes too long time in most cases and a dictionary will contain only a few words this long and even the rainbow tables become too large for normal use. They can only be successful if enough limitations are known and the overall size of the table can be limited.
