Formation of Aluminum (Al) Nanoparticles in water by femtosecond laser ablation is studied numerically by considering the effect of femtosecond laser parameters, target and liquid properties. The absorption of laser energy by Aluminum is simulated using Single-Temperature Model (STM) and results obtained from this model are compared with experimental studies. Classical Nucleation Theory is used to calculate free-energy of critical clusters production and size distribution of nanoparticles (NPs) as function of laser energy and pulse duration in femtosecond range by considering concentration and delay time during the laser generated plume expansion in liquid. Finally, we deduce and point the optimum condition for the growth of Aluminum NPs of desired size and dispersion using STM.

This study was designed to produce microbial polysaccharide xanthan by using Xanthomonas campestris, which is used widely in food and pharmaceutical industries as well as in oil extraction using alkali hyrdolysate of date extract as a carbon source for the growth of bacteria and production of the polysaccharide. In addition, the objective of this study was to enhance the production of xanthan by the bacteria by finding the most favorable conditions of agriculture. It was revealed that the most optimal incubational period was the fifth day where 3.7 g/l was produced (75.57%). Upon addition of different concentrations of extract of fermentation to the medium, the production was increased up to 4.71 g/l (80.47%). It was further increased on addition of 0.4% of magnesium phosphate 0.4% to the nutritional medium. It was shown that ammonium phosphate was the best tested nitrogen source, where 11.19 g/l of xanthan was produced. It was also found that the revolution speed of centrifuge has a stimulating effect on the production of xanthan, in which 200 revolutions/min increased the production up to 13.03 g/l (154%).

Encapsulation inside and adsorption of Lithium alkali metals (Li) on the surface of magnesium oxide armchair - nanotubes (MgONTs) with different diameters (3×3, 4×3, 5×3, 6×3, 7×3 and 8×3) was investigated by using density functional theory. According to the obtained results, the adsorption on the oxygen site of tube surfaces with adsorption energies with energies in the range of −0.93 to −1.11 eV are most stable than the encapsulation complexes in the range of −0.51 to −0.99 eV. Energy gap (Eg) of the nanotubes dramatically decreases upon the encapsulation / adsorption of the alkali metal, resulting in enhancement of their electrical conductivity. The order of energy gap decrement caused by the metal encapsulation / adsorption is as follows: adsorption > encapsulation. Li - MgONTs are photoactives and they have high values of oscillator strengths. The results suggest that the MgONTs were transformed from semi – insulator to semiconductor upon the alkali metal encapsulation / adsorption. Increasing the tube diameter, the adsorption energies of the MgONT-Li complexes are stable and the encapsulation energies of the alkali metal are decreased.

Hydatiosis is a widespread chronic zoonotic parasitic disease caused by helminthic larval stage of tapeworm Echinococcus granulosus.. In last year's many methods are used to activate and modulate the response of immune system of the host in order to evade the invasion of the parasite. The present investigation was aimed to find out the effect of attenuated protoscolices on the viability of lymphocytes which play very important role in the immune response against many parasites and the reflect of this attenuation on hydatid cyst protoscolices infectivity in vivo. Four groups of white male BALB/c mice were experimentally infected with helium-neon laser attenuated protoscolices that exposed to helium –neon laser for (10,30,50,100) minutes respectively. The results showed increase in lymphocyte viability (p<0.01), especially among mice that exposed to laser for 50 minutes (77.00±1.42) in comparison to control group(50.66±3.23),this increase in lymphocyte viability causes statistically (p<0.01) decrease in protoscolices infectivity (both cyst numbers and diameters)in comparison with positive control group which cause decrease in lymphocyte viability.

The rapid development of information and network technologies, networks already become an important part of peoples’ live. People not only can get more information by net, but also can find new ways to live and new business work. For example, network bank, online chat, net-shopping, … etc. Along with the new things' appearance, the problem of information security becomes more important. Something more than authentication is needed. The most attractive solution to this problem is the digital signature which is analogous to the handwritten signature. Digital signature technology more and more shows its important position in information security. The signature is formed by taking the hash of the message and encrypting the message. Digital signatures are used to detect unauthorized modifications to data and to authenticate the identity of the signatory. In addition, the recipient of signed data can use a digital signature as evidence in demonstrating to a third party that the signature was, in fact, generated by the claimed signatory. In this paper, an algorithm for signing text file has been presented. The famous RSA public key algorithm and the most popular hash function algorithms (SHA-1 & MD5) are used to generate the digital signature of a text file. The algorithm consist of two parts: signature generation and signature verification. Many experiments tested to examine the security of the presented work.

Activity time is the elapsed time required for an activity. Estimating is an inexact art, so we expect that our initial duration estimates have some error in them. What we would really like to know is how much this error is going to affect our estimate of the total project duration. Fortunately, with a few assumptions and very little extra work we can make some judgments about the likely amount of variation in the total project time. Estimating activity times is probably one of the project Evaluation and Review Technique's (PERT) most critical features. The concept of three times estimating are used (Optimistic Time, Most Likely Time, and Pessimistic Time). However, the best estimate of the time period (Most Likely Time) in which the activity can be accomplished was provided by experience. In this paper we attempt to optimize the most accurate estimates (Activity’s Most Likely Time) of the activity performance time using simulation . New method was proposed for this purpose and some details was explained about this method. The result show that the simulation is necessary to optimize estimating Activity’s Most Likely time as well as it's flexibility.

E-Government refers to the use of new information and communication technologies (ICTs) by governments as applied to the full range of government functions. In particular, the networking potential offered by the Internet and related technologies has the potential to transform the structures and operation of government. The real benefit of e-government lies not in the use of technology, but in its application to processes of transformation. The sensitivity level of all E-Government systems will be determined based on the sensitivity of the data processed or the importance of the system to mission accomplishment. Security is one of the most important issues in E-government. All systems must include security controls that reflect the true importance of the information processed on the system and/or the government investment embodied in the components of the E-Government system. Zero-knowledge are proofs that show a statement to be true without revealing anything other than the veracity of the statement to be proven. In the other word, The Zero-Knowledge is a concept used in many cryptography systems to allow a party to prove that he/she knows something, without having to send over the value of this knowledge. In this implementation, it will be used to prove the identification of the user without sending over the some pseudo- random numbers. These numbers changing with any sending. In this research we illustrates the zero-knowledge proofs (ZKPs) in e-government security with the fact that there is no additional hardware required. This research managed the security of transmission during e-government process depending on zero-knowledge proofs to Indentify and verify the transmission. The data transmitted over this system are not usable by the hacker to help fake an identity .

Starting from the fact that the Information Technology is a Transformer Technology, this fact applied to one of the most complex Iraqi directorates, which is Karbala Real Estate Registration Directorate, by converting its hardcopy and complicated processes to simple digital one. A big challenge for most of the countries was to digitize this moderate, firstly because storing precious personal properties on a computer or making property transaction is difficult to be assured. The second reason is that this moderate is connected with other moderates to finalize its processes such as the tax office or municipality. The third reason is that converting legislations to software is a very difficult task. The implemented system performed three main processes which were property transaction, property division and property registration. The first step in implementation was by converting the Act of Iraqi Real Estate Registration to software workflow, as it describes any process related to estates (transaction, division, leasehold,…etc.). The second step was entering the real estate’s information in the database. The current process is reengineered and reduced the complications of the routines by means of software security and facilities that provided by the programming language that have been used. The system can solve a number of the sever problems in this moderates, but required to be fully operational by implementing the other parts of the system and connecting it with other moderates.

Currently, multimedia technology is widely used. Using the video encoding compression technology can save storage space, and also can improve the transmission efficiency of network communications. In video compression methods, the first frame of video is independently compressed as a still image, this is called intra coded frame. The remaining successive frames are compressed by estimating the disparity between two adjacent frames, which is called inter coded frame. In this paper, intra frame was transformed using Discrete Wavelet Transform (DWT). The disparity between each two frames was estimated by Diamond Search (DS) Algorithm. The result of the Motion Vector (MV) was encoded into a bit stream by Huffman encoding while the remaining part is compressed like the compression was used in intra frame. Experimental results showed good results in terms of Peak Signal-to-Noise Ratio (PSNR), Compression Ratio (CR), and processing time.

Hair samples (n=236) (control or healthy) individuals were collected from Karbala, a city in south-western Iraq. The study population consisted of males (n=196) and females (n=40). All cases were subdivided according to smoking habits (non and active) so as to compare the levels of trace elements in scalp hair in relation to smoking habits. V, Mn, Co, Cu, Zn, Sr and Cd levels in washed scalp hair were measured by inductively coupled plasma mass spectrometry (ICP-MS). The validity and accuracy of the methodology were evaluated by using a certified reference material GBW 09101 Human Scalp Hair with an acceptable range for elemental recoveries ranging from 90 to 107 %. The results obtained showed significantly higher mean level (µg/g dry. weight) of Sr (11.58) in the scalp hair when compared with the reference range values for control or healthy individuals reported in different countries (0.06 – 6.31 µg/g). It was found that the mean values of Sr and Co were significantly higher in females than males, whilst the levels of V, Mn, Cu, Zn and Cd were similar (at a probability level p = 0.05). Hair of smokers contained significantly more V, Sr and Cd than the hair of non-smokers (at P = 0.05). The levels of Mn, Co, Cu and Zn were similar in both sub-groups of smoking activity (at P = 0.05).

Development of an analytical method was used to determine O-nitro phenol compound by coupling reaction for diazotized solution of p-amino benzoic acid in the presence of buffer solution Na2HPO4 (PH= 10.8) to give a compound with a single azo dye salt having orange color soluble in water with high absortivity at a wave length 449 nm , an early study to have a perfect optimum condition was made for the determination. A calibration curve for a range of concentration (5-75)pm was taken and the value of molar absortivity was 1.5*103 L.mol-1.cm-1 with a relative standard divation more than 1.26% and a recovery 98.77% . As we study the nature of the azo dye by mole fraction method, from the practical value we found that the mole fraction of the dye compound is 1:1(phenol:p-amino benzoic acid) and the stability factor reach to 1.4*106 L.mol-1 .

In this paper a polarographic behavior of rare earth cations (Pr 3+, Eu3+ and Gd3+) complexes with crown ethers was studied. The factors that effect of diffusion current was investigated, it was found that 0.1M KCl is the suitable supporting electrolyte with drop time of 1.4 sec. Direct current polarography revealed half wave potential E ½ of –1.496V, -1.507V and –1.524V for (Pr 3+, Eu3+ and Gd3+) respectively. A shift in half wave potential of metal ions to negative values by adding the crown compound to the metal ion indicates the complex formation. The extraction of the complexes of Pr (III), Eu (III) and Gd (III) with crown compounds (B15C5, 18C6, B218C6 and B2 24C8) were performed with picric acid in different organic solvents. The slope analysis methods indicates that Pr 3+, Eu3+ and Gd3+ forms 1:1 complexes with B15C5, 18C6 and B2 18C6. In addition Pr 3+ form 1:1 complex with B2 24C8 while other ions forms 1:2 sandwich complexes with B224C8. The results of the extraction of Pr 3+, Eu3+ and Gd3+ are a good agreement with the results obtained polarograpically.
