Building the foundations of a formal system of the laptop table: حنان غازي صالح
...Show More Authors

The study of the laptop computer table is one of the important studies at the present time due to the importance of electronic computers that are used in work sites and homes for very long hours, so one of the most important basics of caring for the comfort of the user lies in the design of the laptop table in different shapes and sizes and multiple functions in addition to calculating the measurements of the human body and the extent Its compatibility with the design and measurements of laptop computer tables by taking into account the calculations and measurements of the dimensions of the user's body of all ages and their consistency and use with the general measurements of the tables and the importance of research comes through the establishment of a knowledge base covering the topic of research to be of benefit to designers and specialists in this field and of benefit to product users as this study is It included all aspects of the tables, and the aim of this study was: to find foundations for building the formal system for the laptop table to be more suitable for the user. As for the limits of the research, the study of the formal system for the laptop table of the Chinese company Havic and available in the Iraqi market during the year 2011-2012 This study contains four chapters, the first chapter includes the research problem and the need for it in addition to oh The amount of research and its objectives and limits. As for the second chapter, it included the previous studies and the theoretical framework, which in turn contained three topics, the first was titled Foundations of Building the Formal System for the Laptop Desk and it contained an overview of the laptop computer, the laptop table, the system, the shape, and the second topic was titled Multifunctionality of the Laptop Table The third topic is on the mechanism of the human body ergonomics and its relationship to the laptop table. And then this chapter ended with indicators. The third chapter includes research procedures and methodology, and includes description and analysis of sample samples according to the axes analysis form. Finally, the fourth chapter included the results of the analysis, conclusions, recommendations and proposals. 1. The design system was distinguished by the efficiency of the functional performance and it helped in that the flat and supportive surface of the table surface in addition to the mechanism of the movement of the legs up and down as well as laterally and this achieved a distinct performance aspect although there were no fans for cooling The laptop computer while working and this was achieved in Form No. (1) and the percentage was 50%, while Model No. (2) achieved higher efficiency in functionality due to the presence of fans and the percentage was 50% .2 The dimensions of the computer tables differed according to the user’s need, as they were voluntary To the user as he wants through the size of the table tops and its inclination mechanism in addition to controlling the height and drop of the table legs. 3 The interconnectedness between the design parts aims to influence the functionality in a good way and this was achieved through the use of appropriate fastening means for the mechanism of movement and movement of the table by 50%

Determination of the Fertility of Southern Iraqi Soil Using Laser - Induced Breakdown Spectroscopy System
...Show More Authors

In this work, seven soil samples were brought brought to study and analyses the element concentrations from different southern regions of Iraq using laser-induced breakdown spectroscopy (LIBS) technique. It has been documented as an atomic emission spectroscopy (AES) technique. Laser-induced plasma utilized to analyze elements in materials (gases, liquids, and solids). In order to analyze elements in materials (gases, liquids, and solid). The Nd: YAG laser excitation source at 1064 nm with pulse width 9 ns is used to generate power density of 5.5 x 1012 MW/mm2, with optical spectrum in the range 320-740 nm. From this investigation, the soil sample analysis of the southern cities of Iraqi, it is concluded that the rich soil element of P, Si,

Calculate of the Rate Constant of Electron Transfer in TiO2 – Safranine Dye System
...Show More Authors

         A theoretical calculations of the rate constant of electron transfer (ET) in a dye – semiconductor system with variety solvent are applied on system contains safranineT dye with TiO2 in many solvents like water, 1-propanol, Formamide, Acetonitrile and Ethanol.

    A matlap program has been written to evaluate many parameters such that, the solvent reorganization energy, effective free energy, activation free energy, coupling matrix element and the rate constant of electron transfer.

    The results of the rate constant of electron transfer calculated theoretically are in a good agreement with experimental and theoretical value

Effect of Annealing on the Crystallization of Poly Vinyl Chloride for Drug Delivery System
...Show More Authors

Poly vinyl alcohol has been studied for its ability to form crystallites by using annealing method. Semicrystalline films of poly vinyl alcohol (PVA) were prepared by casting 11.5 wt. % and 13 wt. % PVA aqueous solution onto glass slides at annealing temperature range 90 -120°C and duration time 15- 60 minute. This allowed the macromolecules to form crystallites, small regions of folded and compacted chains separated by amorphous regions where single PVA chain may pass through several of these crystallites. Degree of crystallinity of PVA films (hydrogels) was determined by method of density; on the other hand the swelling behavior was conducted by the determination of water uptake, wet degree of crystallinity, gel fraction and solubilit

Calculation of the Radionuclide Concentrations in Samples of Condiments by Using Gamma Spectroscopy System
...Show More Authors

 The aim of this work  is to evaluate concentrations of  natural and artificial radionuclide  in nine different samples of condiments from local markets.     The concentrations of 238 U , 232 Th ,40k  and 137Cs  were measured by using gamma spectroscopy with a high- purity germanium detector. The concentrations of 238 U, 232 Th ,40k  and 137Cs   were found to be in a range of  (21.4 - 91.13), (15.7 - 88.11) , (285.56 – 1100) and (5.1 - 27.5) Bq.kg-1  respectively. These concentrations are not hazardous to public health and the activities are within the allowed  levels
