Abstract New series of mixed ligand complexes of some divalent transition metals with some bi-dentate ligands such as o-phenylenediamine , anthranilic acid, L-alanine and phthalic acid have been prepared and characterized using different techniques , in particular elemental analysis infrared spectroscopy, electron paramagnetic resonance and molar conductivity . Element analyses data reveal that the prepared complexes were formed in MLL ' (1:1:1 ra-tio). Infrared spectra exhibit one mode of chelation site, through oxygen side of the hy-droxy1 group in COOH and nitrogen side of the amino group (NH2). Electron paramagnetic resonance spectra indicated the presence of paramagnetic phenomena and supported the geometrical structures of the complexes under investigation , being either octahedral or square planar. The molar conductance measurements indicated non-electrolytic complexes. .

Abstract The aim of the paper is to study the relationship between the internal migration and distance in Iraq , using the 1997 Population census data . The research shows that there are many interchange streams between the near by Governorate . The relationship between streams will in-crease if will consider the distance as an effective factor except for Baghdad governorate . The Paper shows that the Correlation between migration and distance appeared to be negative. Bagdad Governorate occupied more than half of the total interchange net migration streams between the profitable governorates, the Middle Eu-phrates governorates more than one fifth than streams, and the other govern-orates more one fifth also. Later, the migrants started to migrate to the nearby places because the government limited the migration to Bagdad , after the 1987 Population Census . Finally , the research shows also that there are Patterns of the profitable governorates in the west if Iraq, and another Pattern of the loser governorates Extending to the eastern and southern and parts of Iraq. .

Abstract Tomato yellow leaf curl virus (TYLCV) is considered as one of the most important viruses on tomato in both protected and open field cultivation in Iraq . several trials were carried out to limit the losses causcd by this virus through the use of insecticides to control Bemisia tabaci. Vector of this virus. Also,several kinds barrier plants were used to limit the movement of the vector and clean it out of the virus before its arrival to tomato plants . This study was designed to determine the effect of alcoholic extracts of henna (lawsonia inermis) thuja (thuja orientalis) and Tamarisk (Tamarisk brachystachy) on the multiplication of TYLCV in tomatoe. The virus multiplication was followed by immune-double diffusion test. The antiserum of TYLCV was obtained by inccting 1.72mg of virus in arabbit at four times (0.43 mg / m) for each ) two intravenously without freund adjuvant and two intamuscularty with an equal volume of incomplete freund adjuvant at intervals of one week. Results showed that effective concentration of Henna and Tamarisk extract was 4000 ppm with protective period of 10 days , where as that for Thuja extract was 3000 ppm with protective period of 12 days . No effect on the plants growth due to the application of the extracts was abserved. .

Abstract The present research edeals with an important issue in the Islamic financial system i.e , the fathers , sons, responsibility in marrying each other if need be , as well as the support of their wives . Is this responsibility part of compulsory expenditure in cumbent on fathers or sons ? The raising of decent family in Islam can only be achieved by Com- mitment to the costs and other lawful duties imposed by Islam . Especially mutal financial commitments among members of a given family . The present research has focussed on this paortial issue by clarifying the evidence as will as the opinions of Islamic scholars . These opinions manifest the interest of the Islamic Law in the welfare the Islamic Society . .

Abstract Root-kont nematodes reducc crop production annually by about 5% world wide . In Wadi Hadhramaut , Republic of Yamen , Onion cultivation is affected by thid pathogen . In infected areas, Loss of Onion yield is estimated by 53.5% . In severe infected plots reached 81% . Field studies were conducted to in vesstigate the effect of a non chemi cal method to control Root-Kont nematodes on Onion . A naturally in fected area was coverd with transparent sheet of polyethylene for three different periods , in cluding an un covered control . 60.45 and 30 daysof Soil Solari –zation decreased the disease uncovered control . Onion Yield signilicantly . Increased to 300 . 252 and 184 % for the three tested periods respectivcly . .

Abstract New series of mixed ligand complexes of some divalent transition metals with some bi-dentate ligands such as o-phenylenediamine , anthranilic acid, L-alanine and phthalic acid have been prepared and characterized using different techniques , in particular elemental analysis infrared spectroscopy, electron paramagnetic resonance and molar conductivity . Element analyses data reveal that the prepared complexes were formed in MLL ' (1:1:1 ra-tio). Infrared spectra exhibit one mode of chelation site, through oxygen side of the hy-droxy1 group in COOH and nitrogen side of the amino group (NH2). Electron paramagnetic resonance spectra indicated the presence of paramagnetic phenomena and supported the geometrical structures of the complexes under investigation , being either octahedral or square planar. The molar conductance measurements indicated non-electrolytic complexes. .
