Silver nanoparticles (AgNPs) are broadly designed for various application. In the current research silver nanoparticles (AgNPs) have been examined for their poisonous outcome on human lymphocyte and chicken embryo fibroblast cell line. AgNPs were synthesized by a simple and easy method from AgNO3 solution with glucose exposed to microwave radiation. The typical size of AgNPs were 30 nm with spherical shape. The cells which cultured with diverse concentrations of silver were examined for their viability using MTT assess, a photometric technique to conclude cell metabolism. The results show that the cell viability of the both cell type were diminished significantly (P<0.05) in dosage dependent mode, and the silver nanoparticles presented higher cytotoxicity to CEF than to human lymphocyte at the same concentration and time point.

Journal of University of Anbar for Pure Science , Volume:12 Issue:2

The artichoke (Cynara scolymus) belongs to Asteraceae family. It is included in British and European Pharmacopeia and has long–used in traditional medicine in several countries. The plant primarily grows in North Africa and Mediterranean; in addition, it is cultivated around the world. Artichoke is wildly distributed in Iraq at the watery lines and boundary of the field. The aim of study was to induce callus from leaves as explants, and to compare between contents of total phenolic and total flavonoids that extracted from the induced callus and from leaves. The induced callus was maintained on Murashige and Skoog (MS) medium supplemented with Naphthalene Acetic Acid (NAA) and Benzyl Adenine (BA). The highest percentage of callus (100%) was induced from the combination (5mg/l NAA plus 2 mg/l BA), followed by (86.67%) with the combination (3mg/l NAA plus 1mg/l BA). Two types of callus (friable and compact) were induced. The extract of friable callus produced 0.858 mg/g of total phenolic, while leaves extract produced 167.24 µg/ mg of total flavonoids. Auxins and cytokinins that added together in the culture medium seemed to be necessary for artichoke tissue culture.

A model depend on ratio number atoms of the Surface to the internal atoms used to calculate the mean bonding length (dmean(r)) of silicon nanoparticles with radius (r) in the range of (1.2nm ? r ? 10nm). The results compared with the (dmean(r)) which measured from high resolution transmission electron microscope (HRTEM) in the range of (r), using AUTO CAD software for measuring nanoparticle radius and the spacing between adjacent fringes that correspond to dhkl – spacing. The results obtained that the theoretical model is in good agreement with the experiment for all (r) range. The lattice parameter (dmean(r)) are found to increases from (0.235nm) for bulk Si up to (0.262nm) for nanoparticles having a size down to 3nm, then it is increased sharply at about the critical radius of silicon nanoparticle (r = 1nm), which related to the atomic surface behavior

A Proposed Method for Achieving the Confidentiality of Arabic Texts

Yaseen Hikmat Ismaiel

Journal of University of Anbar for Pure Science , Volume:12 Issue:2

Due to the rapid development of distributed computing systems, the use of local networks, and the huge expansion of the Internet, the process of maintaining the confidentiality of information becomes important and necessary. Encryption is one of the most important ways to keep information confidential and to prevent unauthorized people from disclosing this information. Many cryptographic algorithms have appeared in different ways and methods. But most of these algorithms have been devoted for encrypting texts in the English language. Because of the increasing important and sensitive information exchange in the Arabic language by users on the Internet, an urgent need has appeared to build dedicated encryption systems for the Arabic language. The aim of this research is to provide a proposed encryption method that uses the idea of combining the methods of transposition and substitution cipher for the purpose of Arabic texts confidentiality. This research depends on using diacritics in the Arabic language to perform the process of substitution cipher. The efficiency of the proposed method has been tested on different texts; the method provides high speed execution, the length of the encrypted texts is almost close to the clear text length, and the confidentiality of the resulting encrypted texts is high.

Journal of University of Anbar for Pure Science , Volume:12 Issue:2

The concentrations of Pb2+ and Cd2+ in the blood of 30 persons working in the Liquid Battery Factory in Baghdad were measured applying the Differential Pulse Polarography (DPP) method. It was found that for the majority of the blood samples, the Pb2+ concentration valueswere acceptable and within the acceptable natural limits(10-20µg/100ml).Exceptionsare 4 samples which showed higher lead ion concentrations. The infected persons worked at a location with high lead presence in the factory. As for the measured Cd2+ concentrations, the results for all the blood samples showed normal values, within the defined acceptable concentration (5.4µg/100ml). However, onconsidering the other defined acceptableconcentration, as reported in the literature, (3µg/100ml), three workmen were found, to have higher Cadmium ion concentration in their blood. It was also found that, compared with the calibrated DPP results, themeasured Atomic Absorption Spectroscopic (AAS) results showed much higher concentration values and should therefore be not acceptable. The measured concentrationsofboth ionswere independent from the age of the workers. Inspections for the presence of Cu2+ ions in the blood samples failed in detecting any traces of it.
