Tow type of Gemini surfactants cationic were prepared for the hydrophilic, 4,4`- Oxy bis (N-hexadecyl benzene ammonium di bromide ) (H2), and N, N-di hexadecyl-4 (4-hexadecyl ammonium)phenoxy benzene ammonium di bromide (H3) these compounds diagnosed by technical of ( lR,1 HNMR and 13 CNMR), also applied by calculating the balance between hydrophilic groups and hydrophobic emulsifying Breaking of Emulation groups HLB, and prepared two types emulsifying Breaking of Emulation of doping aforementioned surfaces and evaluated the efficiency in oil water separators and compared with commercial de emulsifier Rp/6000 ,it was less efficiency from commercial de emulsifier .

A study was conducted during winter season of2011-2012 in a polyethylene house under desert region at Al-Zubair-Basrah province to evaluate the effect of grafting of two indeterminate cultivars (Randy and Shannon) on two different rootstock (Spirit and Beaufort) by two method of grafting (cleft and approach) and compared them with un-grafted plants for both cultivars in growth and quantity and quality of yield. Experiment included 10 treatments implemented by randomized complete block design with three replicates and means were compared by revised least significant difference test at test 0.05 level. Results showed approach grafting method was superior in success of grafting compared to cleft grafting. Both grafting methods caused significant decrease in plant height, total number of leaves, percent of infection by diseases that transferred by soil, total acidity and total soluble solids compared to un-grafted plants.

The research study and compare the effect of the use of natural coagulation assistant extract leaves conocarpus with alum and iron trichloride. The study was based on a series of tests (Jar - test) on the raw water turbidity ranged between (17 - 20) Mg /lwater raw Turbidity manufacturer of (75) Mg / l have been used doses of different Assistant curdling natural and of coagulants basic (alum , and iron trichloride) were measured turbidity final (Turbidity) the after-treatment has been found that the reduction ratios of turbidity was perfect in the case of the use of natural Assistant coagulation with alum or iron trichloride Compared with alum alone or ferric chloride alone. The results of the use of natural coagulation assistant with Alum approach or slightly better compared with the use of assistant coagulation with iron trichloride. It was the degree of movement and function acidic effect on the process of coagulation and sintering was observed that raising the temperature in the case of using the assistant curdling natural unity has given positive results, the percentage of reduction of turbidity to (100%) has a temperature (55, 65) C° and the percentage of reduction (84.5 %) has a temperature of 45 C°

The alga Lyngbya aeruginosa Menegh. Ex Gomont isolated from shutt Al-Arab river in the south of Basrah city. The alga culturing in the modified medium of Chu-10. Two compound were identificated by using GC-mass which is represented by compound Tributyl acetylcitrate and 1,2-Benzenedicarboxylic acid.

The paper deals with the role of image states on charge exchange during scattering of Li atom in its ground and excited states (2s,3s,4s) from Cu(111) surface, where we calculate the positive ionization probability of atomic level of the alkali atoms by using the ( ) interaction levels method, in which the Hamiltonian operator is written by Dirac-notations formula and taking into account both life times for atomic levels and image levels. The positive ionization probability of atomic level and final probability are drawn as function to scattering time and the inverse velocity. We note that the effect of image states appear as an oscillations at high velocities in curve. The amplitude of these oscillations differs for different alkali electronic states, which is increase as the energy of the atomic level increasing.

The present study was conducted in a private orchard at Abi El-Khassib District , Basrah Governorate during the growing season of 2012 on date palm trees "Phoenix dactylifera L." cv. Barhi aged 15 years old to investigate effect of spraying seaweed extract "kelpak" at concentrations of (0 , 8 and 16 cm3.L-1) and NPK fertilizer at concentrations of (0 , 4 and 8 gm.L-1) and their combinations on nitrogen , phosphorus , potassium and total protein concentrations of leaf and fruit . Results showed that spraying treatment of 16 cm3.L-1 kelpak recorded significant increases in phosphorus and potassium concentrations of leaf at Kimri stage , nitrogen and phosphorus and potassium and total protein concentrations of fruit at all stages of growth and ripening . Spraying treatment of 8 cm3.L-1 kelpak significantly increased nitrogen and total protein concentrations of leaf and fruit at Kimri stage . Spraying treatment of 8 gm.L-1 NPK recorded significant increases in nitrogen and phosphorus and potassium and total protein concentrations of leaf at Kimri stage and of fruit at all stages of growth and ripening . The bi-combination of spraying kelpak at 16 cm3.L-1 and NPK at 8 gm.L-1 recorded significant increases in nitrogen and phosphorus and potassium and total protein concentrations of leaf at Kimri stage and of fruit at all stages of growth and ripening . The bi- combination of 8 cm3.L-1 kelpak and 8 gm.L-1 NPK significantly increased nitrogen and total protein concentrations of fruit at Kimri stage

The positive parity energy levels of even-even 186-194Pb nuclei have been studied by using interacting boson model (IBM) with N0 bosons number. The interacting boson model with configuration mixing (IBM-CM), which takes into account the two-particle-two-hole (2p-2 h) excitations is applied. A sequence of (01+, 02+, 21+,……………) levels has been investigated, and compared with available data. According to this study, the 02+ states are N0+2 space. The electric quadruple transition probabilities between the levels are analyzed in decomposition which reveal the detailed nature of the energy levels. The results obtained are found in good agreement with recent experimental data. It was pointed out that interacting boson approximations are equitably reliable.
