Abstract: This study entails some of the theoretical characteristics of Bose - Einstein intensification of the ideal gas properties, since the wave function behavior has been studied and analysed according to the effect three types of external potentials trapping that are used in the production Bose - Einstein condensation which are (harmonic potential, optical lattice potential , and double well potential) that have been used as individual or overlapping potentials, and the value of the non - linear has been confirmed according to fixed values in the whole study in order to the study the effect of the other elements. The effect anisotropy AL has been studied according to the behavior of the wave function and the distribution potential where the harmonic potential has individually at first, than it has been overlapped with the optical lattice potential in order to study this factor. Furthermore,the effect of this factor has been explained due to the distribution potential, function wave and relation type between the factor itself, chemical potential and energy. Additionally, we have used the intertwined harmonic potential with the optical lattice to study the effect of optical lattice potential factor q after confirming the harmonic potential AL at certain values, with exposition of it's effect the wave function behavior and distribution of potential with explanation to the nature of the relation between the chemical potential and energy with this factor. In addition to that, we have studied the influence of the center of double well potential coefficient A on the nature and behavior of the wave function and potential, and the nature of the relationship between this factor and chemical potential and energy. Noting the effect of these factors on the behavior of the wave function and the distribution of potential, therefore it has effect in Bose - Einstein condensation production.

Abstract: In this work, the dynamics of electron transport through a system consists of qubit (two coupled quantum dots) electrostatically coupled with single - electron transistor (quantum dot coupled to leads). The time - dependent Hamiltonian, that is used to describe the system energy, includes the electrostatic coupling between the qubit and the single - electron transistor. The time - dependent equations of motion for all the creation and annihilation operators are expressed in Heisenberg representation to derive the differential equations of motion for the quantum dots occupation numbers of the qubit and the single electron transistor, the related equations of motion for the correlation functions and also the formula that calculates the current which tunnels from the left lead to the single - electron transistor quantum dot. The system of equations of motion are treated by using the wide band approximation, and are solved numerically by using six order Runge - Kutta method, where the error is calculated at each step of time. By getting use of the system of differential equations solutions, the qubit and the single - electron transistor quantum dots occupation numbers are calculated as a function of time, in addition to the current that tunnels from the left lead to the single electron transistor quantum dot as a function of time.The main goal of this study in to investigate the effect of the parameters that related to the qubit and the single - electron transistor and their role in determing the electron transport process features through the whole system. These parameters, that are related to the initialization, manipulation and measurement processes, are the qubit and the single electron transistor quantum dots energy levels, the coupling strength between the qubit quantum dots, the electrostatic coupling between thequbit and the single electron transistor in addition to the coupling strength between the single - electron transistor quantum dot and the leads as well as the leads properties such as tempreture and band width. The effects of quantum dots energy levels tuning and the symmetry of the coupling with leads on the electron transport through the system are also investigated.Our study highlights four important physical features that related to the initialization, manipulation and measurement processes, these are : 1. The occupation numbers of the quantum dots of the qubit and the single electron transistor and the current of SET at the final time of measurement.2. The charge accumulation on the qubit quantum dots, at the final time of measurement, on the far - removed quantum dot and the nearest one to the single - electron transistor, that can be controlled by appling bias voltage and gate voltage.3. The determination of the time - current dependence if it follows the dependence of the far - removed or the nearest qubit quantum dot occupation number on time.4. The role of qubit energy levels tunning and the asymmetric coupling with the leads in determining the suitable initialization and manipulation processes get the quantum measurement with high quantum efficiency.

The results show higher indoor radon levels and radon effective dose especially in kitchen as compared to other locations. High values of radon activity may be due to use of water and cooking gas in kitchen.The average annual effective dose for kitchen varying from 2.316±0.172 mSv/y recorded in Al Nasiriya district to 0.759±0.0348 mSv/y recorded in Suq AlShyouk district.The second study used 186 samples of LR 115 Type II dosimeters collected from 57 Hospitals and Health centers, also Passive method is used to measure the radon indoor levels and lung cancer risk. The results show that the calculated indoor radon levels and radon effective dose in Hospitals are higher than that in Health Centers.The maximum average annual effective dose in Health Centers is 2.504±0.114 mSv/y , while for Hospitals is 3.150±0.091 mSv/y.In the two studies most of the radiation dose are not higher than the world wide average back ground dose of 2.4 mSv/y and hence they does not pose any serious threat to the occupants.The third study aims is to measure the concentration of boron in waters of Thiqar Governorate (southern of Iraq), the water is supplied from two major sources (Tigris and Euphrates Rivers). 165 samples collected from 55 location for three types of water (rivers water, Tab water, drink water). Colorimetric curcumin method is used to measure the boron concentration in the water samples. The maximum Boron concentrations in Thiqar Governorate for River water (surface water) (1.729 mg/l) in Nasiriya district, Tab water(0.3 mg/l) in Chibiesh district and Drink water (0.286mg/l) in Chibiesh district. The results shown that Euphrates river is more polluted with boron element, because its pass in highly occupied region and meager factories ,facilities lay on it, where Tigris average value 0.244 mg/l,while Euphrates average value 0.794 mg/l.The present work shows most of the boron concentration in Tigris river aren't higher than the world wide back ground <0.5 mg/l. In general Euphrates river results are higher than the world wide back ground, but it's still in the low concentration levels for boron, where the European Union established a value of 1.0 mg/L for boron in 1998 for the quality of water intended for human consumption, also New Zealand has established a drinking water standard for boron of 1.4 mg/L

Abstract: The present thesis Conducts polymer (polyaniline) doped with Dodycyl Benzene Sulfonic Acid (DBSA) was prepared by chemical polymerization and with the help of ammonium persulphat (NH4)2S2O8 as oxidizing agent.Multi well carbon tubes MWNTs are ultrasonically treated with strong acide using a 3 : 1 mixture of concentrated H2SO4 and HNO3, producing carboxylic groups c - MWNTs .Nanocomposite conducting polymers PANIDBSA/ MWCNTs was prepared with adding different weight ratios (0%,1%,2%,3%,5%)(MWNCTs to PANI - DBSA). Accordingly, films of these nanocomposite polymer were prepared by spin coating technique .To study the optical properties, these films were deposited on glass, and on interdigitated finger electrode for the - electrical properties.The chemical structure of the prepared polymers PANI - DBSA, c - MWNCT and PANI - DBSA/MWCNTs are characterized by the FTIR spectra .The results indicated an appearance of functional group of doping with DBSA and MWNCTs changed to c - MWNCTs.The structure of preparation films are characterized by X - RAD diffraction .The results show crystalline peaks partial crystallinity of the PANI - DBSA/MWNCTs. The grain size of polymer was calculated by Scherrer relation.Morphologies and diameters of the nanocomposite were studied by Atom ic Force Microscope(AFM) and Scanning Electron Microscope (SEM). The average diameters of nanocomposite change between (81 - 118) nm and the roughness increased with increasing of MWNCTs in nanocomposite. Ology and the thickness were measured by Scanning Electron Microscope (SEM).The result shows the polymer covered MWNCT.The optical properties of preparation film were studied from absorbance spectra at wave - lengths of (300 - 1100 nm). The analyses of optical measurement shows direct transition with energy gap decreasing increases MWNCTs about(3.4 - 1.9) eV. The reflection spectrum is analysed to find same optical constant like extension coefficient and refraction coefficient.The electric conductivity was measured and it was found that the thin films correlate with the ohmic behaviour at voltage under 10V.The electricalconductivity increases as the ratios of MWNCTs increases in PANIDBSA/ MWNCTs nanocomposite from(6.17x10 - 3 S/cm ) at 0wt% to (1.12x10 - 1 ????/cm ) at 5wt% .The effect of temperature on the electric conductivity of all ratios of thenanocompositesare also studied. The resultindicated the activationenergy decrease as MWNCTs increase from 0.15 at (0wt %) to 0.05 at (5wt %).In electronic applications of nanocomposite conducting polymers solar cell,two kinds of solar cells (ITO/TiO2/PANI - DBSA/MWCNTs/C/ITO ) and (ITO/TiO2/PANI - DBSA/MWCNTs/dye/C/ITO) were fabricated. The currentvoltage characteristics are measured at light source 100mw/cm2.The solar cell parameter like open circuit voltage VOC ,short circuit current JSC, shunt resistance RSh, series resistance RS, full factor FF, and efficiency η, are calculated. The efficiency of solar cell at different ratios of MWNCTs in PANI - DBSA/MWNCT were calculated. The result indicated that the efficiency increased as MWNCTs increase. The efficiency of solar cells also increases with adding dye.
