The research summarizes the use of remote sensing techniques represented by satellite images captured in 2004 in order to prepare the specialist to deal with Arc GIS erosion map of the Wadi Al-Batin Fan in southern Iraq. The 9.3 program was used with spatial data, aerial photographs and satellite images and in drawing different maps and conducting analysis on different types of spatial data.
The satellite image was prepared in order to draw the dry valleys in the Wadi Al-Batin Fan and the length of each dry valley was calculated in order to clarify the Interpolation The satellite image was subjected to the Bergsma command and using the equation for classifying the degrees of erosion in the region.
The results showed the presence of four degrees of erosion in the region and the area of ​​each degree of erosion was calculated and it was found that the non-erosion range is the dominant one in the region

In this research, a practical study was conducted for two different designs of solar water heaters that operate by natural circulation. The study included testing two solar water heaters, the first has four glass faces (the upper, front and side faces) except for the back face and the lower base which are made of wood, and the second has only one glass face which is the front face and the rest of the faces are all made of wood. The test was conducted under different climatic conditions of the city of Basra (2010\12\2010 and 26\12\2010 and 23\12\2010 for three days only, which are (22). These results showed an advantage in the performance of the heater with one glass face over the heater with four glass faces, 38% - 49% for the heater with one face, and the efficiency ranged between (% 44%) (% 67).

In this research, the effect of adding unsaturated polyester resin in different proportions to the Iraqi cement mixture (production of Umm Qasr plant) was studied. Different on the Iraqi cement mixture (production of Umm Qasr plant, treated in three different ways (water treatment, moisture treatment, air treatment), and the samples prepared in proportions of mm150) and containing the weight proportions of the additive to the cement (1 cement/3 sand) and in the form of a cube with a side length ranging from 2%-8%) and with an increase of 2%, it became clear from the results obtained that the highest compressive strength (%) for moisture treatment and water treatment and gradually decreased with an increase in the proportion of 2%, as for air treatment, there was no significant effect of adding unsaturated polyester gum on improving the compressive strength, as it was equal for pure cement with that to which this material was added at the proportion (%), at which the compressive strength increased for the other two treatments (water treatment, moisture treatment).

In this work, the rate of motion of an atomic-sized quantum dot attached to a solid surface will be calculated using a microscope probe, where Hamiltonian described the transition to the Keldysh mode. Therefore, our calculations were based on the non-equilibrium Green's function method for the fixed height STM. The vibrational decay rate due to electron-hole pair excitation, the vibrational generation rate due to inelastic tunneling current, as well as the total rates of vibrational excitation and re-cooling between the potential well levels were calculated and examined. These rates are related to the concept of the so-called effective temperature, which all enter into the calculation of the motion rate as a function of all the processing variables, especially the bias voltage, temperature, and electron-vibration coupling interaction.

A biological experiment was conducted to demonstrate the effect of liquid waste discharged from petrochemical and fertilizer plants in the province of 1:3, industrial waste water only (without mixing) and Shatt al-Arab water, Basra after mixing it with Shatt al-Arab water in the proportions of 1:1 to compare the copper and lead content in corn plants grown in sandy mixed soil. The soil was placed in 4 kg plastic pots and corn seeds were planted at a rate of 10 seeds in each pot. The plants were thinned to three

After ten days of germination, the plants were watered with the prepared dilution ratios.

The results showed the possibility of using industrial waste water in irrigation without causing any damage or pollution to the plant and soil. The rate of copper content in the plant and the available copper in the soil was superior, reaching 0.0399 mg/kg waste, the petro treatment in the rate of waste content of the plant and 0.2330 mg/kg soil, respectively. While the petro water treatment was superior in lead in the plant and reached 0.0297 mg/kg waste. The industrial water was superior only in the rate of copper content
1 in the rate of lead content in the plant and: in the plant and the available copper in the soil, while the mixing ratio was superior in the available lead in the soil.

The efficiency of gasoline in the formalin-ether technique in detecting parasites was evaluated. 90 stool samples were collected and divided into four groups: diethyl ether. The first group did not contain parasitic infections, while the other groups contained single infections of parasites. Each sample was concentrated using both ether solvents (Hymenolepis nana, Giardia lamblia, Entamoeba histolytica 45.5%) of the total number) and gasoline in addition to using the direct smear method. The results of the tests showed that 41 of the samples contained the parasites under study, in addition to the absence of significant differences when using both solvents in the concentration process. The study also showed the ability of gasoline in preserving the morphological characteristics of cysts and eggs, which confirms its use as an alternative to ether, which has many risks.

This experiment was conducted as part of a comprehensive study to investigate the mechanism of salt tolerance of date palm seedlings, Halawi cultivar. The results of the study showed that irrigation with sodium chloride solution at different concentrations (0, 6, 12, 18 and 24) dS/m affected the leaf content of plant hormones and some vegetative growth traits (leaf area and fresh leaf weight). The results showed a decrease in leaf area from 29.99 cm2 to 14.72 cm2 and the fresh leaf weight decreased from 2.40 to 0.84 g in the control and 24 dS/m2 treatments, respectively. Salt stress significantly affected the leaf content of plant hormones, as the levels of auxin-like substances, gibberellins and cytokinins decreased with increasing salt concentration, while the concentration of plant hormones auxins, gibberellins and cytokinins (85.4, 17.4 and 84.6) mg/kg in the control treatment decreased to (20.9, 6.37 and 60.2) mg/kg in the 24 dS/m salt treatment for plant hormones, respectively. While there was an increase in the leaf content of abscisic acid with increasing salt concentration, as the leaf content of abscisic acid increased from 89.58 mg/kg in the control treatment to 131.81 mg/kg in the 24 dS/m salt treatment.
