In the present study new azetidinone derivatives containing sulfa drug moiety have been prepared by cyclocondensation of the Schiff bases derived from sulfa drugs with chloroacetyl chloride in the presence of triethylamine. The Schiff bases are prepared by the condensation reaction of the sulfa drug (sulfadiazine and sulfanilamide) with the 5-nitro-2-furancaroboxyaldehyde. The structure of the azetidinons were confirmed by elemental analysis (C. H. N.) and FT-IR, 1H-NMR spectroscopy. The compounds were screened for their antimicrobial activity against Staphylococcus aureus, Escherichia coli, Aspergilus niger and Aspergilus flavus. The compounds exhibited good antimicrobial activity in comparison with standard drugs.

This research study examine streets dust pollution in Basrah city by heavy metals Pb, Cd, and Cu in this study it has been taking 100 dust specimen .50 from North Basrah and 50 from South Basrah including crowded general streets, bystreets, and from some street nearer to main Stations generators and from some housetops or terraces and gardens of some houses, this study included 25 region in North. and South in' Basrah city where the levels of heavy metals concentration were determined using flame atomic absorption spectrophotometer AAS after the laboratory digestion of dust samples using aqua regia, the study was conducted to include the effects of accumulation of heavy metals derivatives on soil surface as a result of emissions of such heavy metal and to include the effects on the environments. by this research it was found that the highest concentration level of lead in dust of Karmat Ali / Al- najebea (Kr.nj) sample in Karma Ali site equal to 160 mg/L then the maximum level of lead in dust of Hartha site also equal to 85 mg/L in gent sample the lowest level of lead 62mg/L and comparing to level 52 mg/L of lead in dust in Alzbeer site was found in N-Z sample, while the Higher level of lead in dust in South Alzbeer site was found in S-Z sample, equal to 70 mg/L and the lowest level of lead in dust in Karma site equal to 95 mg/L ,while the lowest of lead in dust in North Alzbeer in site St1 45 mg/L and lowest in S-Z 37 mg/L . The Cd and Cu very equality in parts that we are studies so as to concerted in Pb higher differently metal .

Background: Cervical lymphadenopathy is a common problem in children. The condition most commonly represents reaction to an infection in the drainage area but occasionally it might herald the presence of a more serious disorder like malignancy and biopsy is appropriate if there is continued progression or lack of any regression within 4-6 weeks. Immediate biopsy should be sought in the case of an enlarged supraclavicular lymph node or for findings suggesting malignancy such as hard, fixed, or nontender nodes.

The Mechanical properties of (LDPE-463): luffa composite was assessed with respect to the effect of filler content luffa varying from 2.5% to 25% by weight in the composite. Obvious improvement in the mechanical parameters was recorded when adding luffa with 2.5% weight ratio. The mechanical properties of loaded film have been evaluated through several parameters concerning the elastic deformation based on measuring the load – elongation characteristics. The behavior of the stress - strain curve was analyzed in terms of the cold drawing model. Experimental difficulties appeared above 5% mixing ratio, and these difficulties were due to the separation in phase which makes the sample processing impossible. Experimental results showed that elastic behavior increased with increasing luffa filler up to 2.5 % concentration.

: In this paper, we use variational iteration method (VIM) to handle the differential-algebraic equations(DAEs) systems. The results reveal that the variational iteration method (VIM) is more efficient than the ADM and it is very effective, convenient and quite accurate to systems of linear partial differential equations. It is predicted that VIM can be found widely applicable in engineering.

The experiment was carried out in one of the orchards date palm station at Qurna region of the Public Authority for Nakheel, located north of Basra for the growing season 2012. To study the effect of spraying three levels of phosphorus (zero, 100, 200) mg / L / offshoot, and three levels of proline (zero, 100, 200) mg / l / offshoot, and interaction on vegetative characteristics of date palms cv. Aljbjab. The results showed spray treatment with phosphorus concentration of 200 mg / l / offshoot gave a significant effect in vegetative characteristics (number of Palme, Palme length, Alkhosh length and width) and the content of the Palme of the major elements nitrogen, phosphorus and potassium and content of carbohydrates compared other treatment. The proline treatment was a significant effect at 200 mg at all of the above qualities characteristics compared to other treatments, and the interaction between treatment was a significant in all characteristics study .

This study showed the all concentration used 20 , 30, 40 / 100 L gives the high sufficiency and reduced the density of kind of insects aphid significant compare the control
