Morphological and Electrical Properties of gold nanoparticles /macroPorous Silicon for CO2 Gas
...Show More Authors

In this work, the fine structure macro-porous silicon (macroPS) substrate was prepared by photo-electro-chemical etching of n-type silicon wafer. Ultraviolet illumination condition of wavelength 360nm wavelength and intensity of about 100mW/cm2 with etching current density of about 50 mA/cm2 and etching time 5
min was employed. The Hybrid device gold nanoparticles /macroPorous Silicon (AuNPs/macroPS) was fabricated by deposition AuNPs into mPS substrate Via immersion plating process of macroPS in the solution of HAuCl4 with the (10-3M) concentration and 2min immersion time. The characteristics of PS before and after
immersion process were investigated by scanning electron microscopy (SEM), EDS, X-Ray diffraction (XRD), photoluminescence (PL) and Infrared spectroscopy (FTIR). The J-V characteristics of sandwich structure showed that the maximum sensitivity of the AuNPs/macro PS was about (90.5%)for compared with macro-PS substrate. The current-voltage characteristics were performed in primary vacuum with a base pressure of about 0.2mbar and CO2 with 1mbare concentrations.  Significant enhancement was observed in sensitivity of the AuNPs/macroPS hybrid device and temporal response after deposition the AuNPs.

Electroconvulsive Therapy: Attitudes and Practice of Iraqi Psychiatrists
...Show More Authors

Background: Although Electroconvulsive Therapy (ECT) is still regarded as a controversial treatment by some people, it is an important and effective treatment. The practice of ECT is different across the world.

Objectives: to obtain an overview of the electroconvulsive therapy   practice in Iraq.

Method: Forty item self administered questionnaire about the attitude and practice of ECT, was sent (by mail or delivered by the researcher) to 73 Iraqi psychiatrists during the period from March to September, 2007.

Results: Half of participants had asked for the patient's consent, and all asked the family for the consent,    72%

The expansion in water projects implementations in Turkey and Syria becomes of great concern to the workers in the field of water resources management in Iraq. Such expansion with the absence of bi-lateral agreement between the three riparian countries of Tigris and Euphrates Rivers; Turkey, Syria and Iraq, is expected to lead to a substantially reduction of water inflow to the territories of Iraq. Accordingly, this study consists of two parts: first part is aiming to study the changes of the water inflow to the territory of Iraq, at Turkey and Syria borders, from 1953 to 2009; the results indicated that the annual mean inflow in Tigris River was decreased from 677 m3/sec to 526 m3/sec, after operating Turkey reserv

Analysis and Development of Customer Billing Telephony System
...Show More Authors

The telecommunications industry has gone through series of development efforts to provide quality services to their consumers. Generally, telecommunication industry provides two main services such as telephony and internet which involved customer registration, billing and payment. However, the challenge confronting telecommunications industry is to meet the customer satisfaction in the billing system such as accuracy, easy to understand and unambiguous billing issue. In order to develop Customer Billing Telephony System,a user experience study is conducted to gather the user requirements. Hence, the CBTS was developed that takes into consideration user’s value experience that provides a support for managing and monitoring billing proce

Sources of Threatening Educational Security: Means and Effects
...Show More Authors

Today’s world confronts various threats from different sources. Similar to deprivation of energy, economic facilities, or political deposition, educational poisoning is one of the dangerous phenomena that result from distorting and corrupting the ethical and educational components of teaching by various material and non – material means.This paper sheds light on the concept of the educational system which is not a mere process of teaching, but rather an endless process of socialization that begins in the family and develops into religious, ethical, scientific and mythological systems, all of which form the cognitive component. It also defines the necessary means by which it is transmitted from one generation into another. The educati

Chitosan and Keratin Hydrolysate Treatment of Archived Newsprint
...Show More Authors

  The study is focused on the modification of the standardized newspaper with natural polymers chitosan and keratin hydrolysate applied on the paper surface from polymer solution. This modification is based particularly on the formation of the complexes between acidic surface groups on cellulose fibers and the natural polymers which improved the mechanical properties of the paper and the positive results which were observed particularly in folding endurance of the newspaper.

Design and Evaluation of Polygonal Trough Solar Concentrator
...Show More Authors

     In this paper, a solar concentrator is designed in the form of a concave half-cylindrical mirror consisting of polygonal reflective surface plates. The plates are arranged to give a hemispherical shape to the design. These surfaces work to receive solar radiation and focusing by reflecting it to the receiver that is placed in front of the reflecting surfaces. The results are compared with a system consisting of a concave reflecting surface of the same dimensions to obtain a good criterion for evaluating the design performance. The results showed a low acceptance angle for the design for all the samples used due to the geometrical design nature. The optical efficiency affected by the angle of incidence greatly by

The scholars of Arabic - may God reward them with the reward of the doers of good - laid down the rules of this language, the cycle of which never ceases to dazzle minds, so they adopted principles according to which they judged the denomination of this word, and the accusative of that, and determined in its light the worker and the done, until they reached us the rules and foundations of our dear language, and it is obvious that they differ. The origins of grammarians from one school of thought to another, or from one world to another, especially with regard to the subsidiary rules, and this difference was clearly reflected in what we have received from the rules, as we find a difference in the rulings that they restricted to the one fa
