In this work, we have studied many control parameters effect which plays an important role to determine the density concentration of carriers in the Quantum Dot Laser (QDL) system. Our study is based on theoretical model equations which derived from the rate equations. The equations were applied to the GaInAsP/InP QDL with wavelength 1.55μm. We produce a theoretical simulation and analytical solution of the equations by a Mathematical program.Theoretical equations are used to study the effect the parameters by controlling the value of each : the carrier's density and occupancy of the Level of a carrier confined in a QD. There are two cases : when the cross - section of the internal absorption losses has a influential amount and a nather it case when approaching zero border. As well as, we study the impact of the parameters on the threshold current density and its compounds. In addition, we study the role of these parameter to determining the maximum temperature of QDL operation through effect on temperature rang of the system.The temperature effects on the carriers’ activities in the system are studied, whereas the characteristics temperature of QDL has been studied in the two cases : with / without internal losses.The effects of structure and control parameters are applied to Study many factors. Such as : surface density of QD, mean size of QDs, optical confinement layer, spontaneous radioactive recombination time and resonator losses.

Directional couplers can be used to make important planar optical integrated circuits for optical communications, such as Mach - zehnder interferometers and wavelength division multiplexers. Wavelength division multi/demultiplexing of optical signals is an efficient means to increase the information density per fiber.Both the coupled mode theory and the FD numerical method are used in this study to analyze multiwaveguide DCs.In this thesis, we present an analytical expression for crosstalk of MWGDC based on relationship between the normal modes and local modes, where these modes are obtained numerically using FD mothed.Also, the mode field profile and their evolution along the structure are presented through the analytical expression and calculated numerically using FD method. With the help of this analytical expression, the input power can be controlled to be enter from a chosen hannel. This enable us to calculate the crosstalk that corresponds to a certain input channel.The transmission characteristics of a four channel multiplexer based on three MZI can be described in terms of the propagation matrices. In this study, the coupling coefficient of DC and the phase shift of MZI are treated to be wavelength dependent parameters. Crosstalk introduced by such process are also calculated.The transmission characteristics of three arm MZI as a DWDM is investigated theoretically by deriving the propagation matrix of 3WGDC using coupled mode theory. Thus, two parameters are introduced, and , as a designing controlling parameters for DWDM devices. By adjusting these parameters a DW DM devices can be presented.

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.

The study was conducted in Plant physiology laboratory, department of biology, college of education for pure sciences, University of Basrah from 1/6/2015 till 10/7/2016 in order to evaluate the effect ofpretreatment (soaking) seeds of corn (Zea mays L.) cv. Baghdad 3with salicylic acid (SA) on germination, early seedlings growth and to minimize the effect of water stress induced with poly ethylene glycol (PEG). The study included the following experiments : 1 - Effect of SA and PEG on germination using a hydroponic culture and Hoagland solution in which corn seeds were soaked in three concentrations (0.1,0.3,0.5) mMof SA in addition to control treatment with distilled water for six hours. Water stress were induced with PEG at concentrations of 0 (distilled water),1%,2%,3%,6%,9% and 12%. This experiment indicated that the optimum soaking concentration with SA was 0.5 mM and that there was no germination at 12% PEG.2 - Effect of interaction between corn seeds pretreatment with DW, 0.5mM of SA for six hoursand PEG at all previous concentrations except 12%, on early corn seedlings growth using hydroponic culture and Hoagland nutrient solution, for three weeks.3 - Effect of interaction betweencorn seeds pretreatment with DW, 0.5 mM of SA for six hoursand water stress induced with PEG at 3% and 6% on vegetative growth using pots filled with a mixture of sand and peat moss for three months.The parameters were evaluated after each of the previous experiments, also , Biochemical test . Plant height, leaves number, root length and number, dry and fresh weight for shoot and roots, while the followingparameters were evaluated in corn leaves after pots experiment : 1 - Biochemical tests included : proline and glycine betain concentrations, total carbohydrates, total chlorophyll, sodium and potassium ions concentrations.2 - Leaves anatomical study to compare the effect of PEG inducedwater stress and the role of its interaction with pretreatment with SA on thegrowth and development of internal structure of corn leaves.The following results were estimated : 1 - Germination percentage : increasing water stress in the nutrient media reduced the % germination significantly when compared with control treatment. Seeds pretreatment with SA enhanced the germination percent and the highest percent was at interaction between PEG at 1%, 2% and SA at 0.5 mM.2 - Growth parameters for seedling at hydroponic culture indicated that plant height, fresh and dry weight for shoot and roots have increased significantly when seeds were pretreated with 0.5 Mm SA All theprevious parameters were reduced significantly under PEG induced waterstress especially at 9%. Interaction between SAand PEG caused apositive significant increases in all studied parameters especially atconcentrations less than 6% and 9% PEG.3 - Growth parameters for corn plants grown at pots have showed a significant increase when pretreated with SA compared with that treated with DW. PEG caused a significant decrease in the growth parameters IIIespecially at 6%. Interaction between DW and 6% PEG recorded the lowest growth in all studied parameters. 4 - Biochemical tests : There was a significant increase in total carbohydrates and total chlorophyll content in leaves of corn plants pretreated with SA in compare with that pretreatdwith DW while the content of proline and glycine betaine were higher significantly in leaves pretreated with DW.In case of PEG induced water stress, the highest total carbohydrates content was at 6%, highest chlorophyll content at 3% while proline and glycine betaine highest content were at 6% PEG. 5 - Sodium and Potassium Concentration : The highest potassium concentration was at plant treated with SA while the highest sodium concentration was at plant treated with DW. Increasing PEG concentrations caused a significant increase in potassium concentration and a significant decrease in sodium concentration. Interaction results revealed that the highest potassium and the lowest sodium concentrations were at interaction between SA and PEG at 6%. 6 - Anatomical study results revealed that increasing water stress effected the leaves tissues structures and this were cleared at vascular bundles tissues (xylem and phloem tissues) and bundle sheath. Upper and lower epidermis, polliform cells were also affected by increasing water stress.The anatomy of leaves also showed that there was a positive enhancement in the structure of leaves tissues in the plants grown from pretreated seeds with SA.

A total of 210 human venous blood samples were collected from Basrah province ( 190 randomly collected from people living in different regions of Basrah province , 10 blood samples from people who did not have a history of shrimp consumption or dealing with it used as negative control group, anther 10 samples of people who are sensitive to shrimp used as a positive control group). The samples were serologically tested by Enzyme Linked Immunosorbent Assay (ELISA) to estimate the distribution of total and specificIgE in the sera of studied individuals . Polymerase Chain Reaction (PCR) was performed to detect the HLA - DQB1*02 , *0302 , *0305 allels. The immunological study included the preparation of two types of Metapenaeus affinis allergens which are the raw allergens and the boiled allergens used in Indirect ELISA test to determin shrimp food allergies by serodiagnosis , while Direct ELISA test was used to estimate the distribution of total IgE by quantitative serological methods in the sera of studied samples. the concentration of protein in antigens extracts was estimated, the protein concentration in the boiled shrimp extract was less than its concentration in the raw extract.The results of direct ELISA test demonstrated a decrease in the level of total IgE antibodies in most of the studied samples , the level of IgE <100 recorded a significant high rate 98.4% which is more than the level of IgE > 100 which recorded apercentage of 1.6% and there was a significant difference between them. The Indirect ELISA test results revealed that the total percentage of IgE distribution of the raw and boiled shrimp antigens were 57.8% and 74.2% respectively and there was a significant difference between males and females .However , the difference was not significant between the age groups P>0.05.The molecular study was conducted to detect the presence of some alleles HLADQB1* 02, *0302, *0305 gene in the blood samples by using PCR . The current study showed that the association of the presence of these alleles and the level of total immunoglobulin is highly significant.Also the current study showed that a high significant difference was found between the positive samples to the studied alleles and the seropositive and seronegative results of raw and boild shrimp allergen specific IgE based on Indirect ELISA (P≤0.01).The results of PCR showed a high frequency ratio of HLADQB1 * 0302 97.2% in allergic patients of shrimp boild allergen and 56.9% in allergic patients of shrimp raw allergen .Also the current study showed a very high frequency ratio of HLADQB1 *0305 98.2% in the individuals who showed positive results for the raw allergen and recorded 65.2%. in the individuals who showed positive results for the boild allergen ,while HLADQB1*02 showed in one sample of studied samples which recorded positive results to raw and boild allergens of shrimp .The current study demonstrated also that the alleles frequency in some of studied samples which are seronegative by Indirect ELISA test , HLADQB1*0302 was 30.9% in raw antigens, while in the negative boild sample was not observed . HLADQB1*0305 was 1.23% in serongative of raw allergen and 16.32% in boild allergen. However, HLADQB1*02 was notobserved in seronagative to raw and boild shrimp allergen.

This study was conducted to assess the state of submerged aquatic plants in some areas of East Hammar marsh and Shatt al - Arab River, as measured by some of the chemical and physical properties of water and sediment in six stations, three of which are located in East Hammar marsh (Nagara, Sallal and Almshab) and the other three are located in the Shatt al - Arab (the island Muhammadiyah, Salhiya and Mhella). Environmental surveys of submerged aquatic plants were done and registered their presence, their vegetation cover and biomass as well as the biodiversity indices (diversity and evenness, and dominance) for 12 months from October 2015 until September 2016.The air temperature in the East Hammar marsh ranged between 19 - 45.3 C, water temperature 14.3 - 32.4C , transparency between 20 - 100cm , Turbidity between 20.9 - 65.3 NTU, depth of 50 - 160 cm and dissolved oxygen between 5.4 - 6.9 mg / L, pH between 7.6 - 8.6 , electrical conductivity between 3.8 - 12.5 mS / cm, nitrates between102.23 - 549.64 μg/L, effective phosphorus between 4.15 - 9.6 μg/L . As for the Shatt al - Arab River values ranged : air temperature between 18 - 48 C , water temperature was between 14.2 - 32.3 , Transparency between 23 - 90 cm, turbidity between 12.8 - 68.3 NTU , depth of 60 - 200 cm , dissolved oxygen between 5.4 - 7.9 mg / L , pH between 7.5 - 8.51 , electrical conductivity between 2.8 - 12.4 mS / cm , nitrates between 106.17 - 569.42 μg/L, effective phosphorus between 4.93 - 9.13 μg /L .BpH and electrical conductivity values of the sediments in the Shatt al - Arab and East Hammar marsh were reached 7.7 - 8.3 and 1.08 - 2.91 mS / cm and 7.5 - 8.4 and 1.12 to 3.05 mS / cm respectively, effective phosphorus values in sediment ranged in sediment of East Hammar marsh between 5.69 - 42.51μg/L, While in Shatt al - Arab fluctuated between 5.12 - 40.3 μg/L, and the value of the organic matter in the Shatt al - Arab were 5.6 to 14.5%, while in the East Hammar marsh reached 7.4 - 15%. The sediments are similar texture in the Shatt al - Arab and East Hammar marsh (Silty clay).The presence of three species were recorded in the Shatt al - Arab River included Potamogeton crispus , Potamogeton pectinatus and Potamogeton perfoliatus, while five species in the East Hammar marsh Ceratophyllum demersum, Myriophyllun spicatum , Potamogeton crispus , Potamogeton pectinatus and Potamogeton perfoliatus.As calculated biodiversity evidence was that East Hammar marsh was more diverse than the Shatt al - Arab, while dominancy was clear in the Shatt al - Arab, compared with East Hammar marsh.This study showed that the sudden rise in salinity values as well as increased nutrients led to degradation of water quality, which was reflected on the presence and vegetation cover of submerged aquatic plants as well as biodiversity resulting from the presence of Tilapia and other fish that use submerged aquatic plants as food as well as the human factor.
