New chelate compounds, with general formula [M (HL)2(H2O)2]. when [M= Co(II), Ni(II), and Cu(II)] and [M (HL)2].(H2O)2 for Zn(II) and Cd(II), were prepared by reacting chloride salts of these metal with new azo-oxime ligand 2-Hydroxy(3-trifloromethylphenylazo)-benzaldehydeoxime (H2L), which was prepared by coupling of diazonium salt of 3-Methylanilin with Salicylaldoxime. The new azo-oxime ligand and its chelate complexes were characterized by available techniques and the results showed that Co(II), Ni(II), and Cu(II)] chelate complexes have octahedral geometry where Zn(II) and Cd(II), have tetrahedral geometry. The ligand and their metal complexes was tested invitro against the sensitive organisms Staphyllococcus aureus, Streptococcus mutants, Escherichia coli and Proteus mirabilis as antibacterial and Aspergillus flavus, Aspergillus terreus as fungicidal. The activity data show that the metal complexes higher antibacterial and antifungus activity than the free liga

This work was concentrated on preparation of activated carbon which also call (charcoal) from natural agricultural wastes (leg & leaves and empty ear of corn, Wheat & Barley grass and herb residues) and industrial residues (Paper drafts and Sawdust). These residues were treated first with Sodium Hydroxide (1:2) (1 of the raw materials : 2 of NaOH), then burning at 550 ± 25 °C for three hours to complete the carbonization process. The reaction mixture was purified by washing with distillation water and neutralized using 10% Hydrochloric acid. Reflux for one hour, filtrate and washing with distilled water, and leaves to dry at 110 – 120 °C for 24 hours. The physical properties of preparing activated carbon were determined and compared with a commercial activated carbon which supply by B.D.H. chemical company.

Environmental concerns have driven the need to remove sulphur-containing compounds from diesel fuel for reducing of SOx emissions which participates in decreasing environmental pollution and acid rain. As the oxidative desulphurization is conducted under very mild reaction conditions, much attention has been recently devoted to this process.
In this contribution, desulphurization of peroxide in the presence of an acid catalyst such as formic acid, followed by extraction of the diesel fuels has been investigated by chemical oxidation of sulphur containing compounds with hydrogen oxidized compounds using acetonitrile or dimethylformamide (DMF). Oxidative desulphurization (ODS) of diesel fuel was found to be very promising approach for the reduction of up to 85 to 90 % of sulphur content at low temperature (25-50 0C) and atmospheric pressure. The reaction found to be exothermic so, the heat liberated during the reaction maintained continuity of the reaction at higher than room temperature through reaction period, therefore no need to further heating. The flash point of the fuel was decreased and other physical and chemical properties were affected as number of oxidized fuel extraction is repeated. Such extraction also removed sum of other aromatic hydrocarbons and affected the yield.

Extraction of sulphur compound in diesel fuel without oxidation by DMF, alcohol, ethyl alcohol, diethyl ether, acetyl chloride, acetonitrile and other organic solvents were investigated. The investigation showed that the best solvent for sulphur content compound extraction was DMF.
In this study, modifications of the oxidation process occurred including the application of UV. radiation to improve the oxidation process as conducted. The new system required less oxidant and energy as compared to previous generations of desulphurization process without the significant loss of desulphurization efficiency and minimum impact on the fuel quality.

This study recommends that the oxidation extraction technique be used to meet the future environmental sulphur regulations in Kurdistan region north of Iraq

Benzidine was converted to the corresponding bis-diazonium salt which was introduced in coupling reaction with alkaline solution of 2-hydroxybenzaldehyde as coupling reagent to give bis-azo derivative (1) containing two aldehyde groups. The resulting bis-aldehyde (1) was then introduced in condensation reaction with 2-amino-5-mercapto-1,3,4-thiadiazole to produce the bis-imine (2).Then compound (2) was reacted with maleic anhydride and phthalic anhydride to give (3a and 3b) respectively .All compounds were spectral identification by FTIR and 1H-NMR.

Rh(III) chloro complex as homogeneous catalyst has been used in the oxidation of threonine by N-chlorosccinimde (NClS) in acid medium. The reaction shows first order kinetics with respect to NClS and zero order in threonine concentrations, the reaction also shows first order kinetics with respect to Rh(III). The reaction product [succinimide] was added to the reactions and had no effect on the rate of oxidation of threonine by NClS using Rh(III). Changing ionic strength, dielectric constant and chloride ion of the medium has no effect on the rate of oxidation. H2OBr+ and [Rh(H2O) Cl5]-2have been suggested to be the reactive species of NClS and Rh(III) chloride at this pH. The rates were determined at four different temperatures and the activation parameters were evaluated. Aldehyde have been identified to be the oxidation products of the reaction.

Obesity is an important factor associated with lifestyle-related diseases, and this factor may be related to periodontitis. Aims of the present study were to investigate the effect of obesity on gingival health ,pocket depth and gingival recession of both genders in Erbil city.
Methods: Body Mass Index (BMI) was determine for (200) patients who had regular daily tooth brushing; visiting Erbil medical centers. Clinical examination of the periodontal health was performed by reporting plaque, gingival indices, pocket depth and gingival recession among males and females individual.
Results: obese females reported the greater mean of PLI, GI, GR and PD than obese males; with statically significant differences of PLI and GI between obese males and obese females (P ≤0.008 and P≤.003) but statistically not significant difference was found for healthy and pre-obese groups for both genders. , also statistically not significant differences were found for gingival rescission and pocket depth between the male and female groups for all parameters. all study parameters in male and female revealed a highly significant difference between healthy & pre-obese, healthy & obese and pre-obese &obese groups (P ≤0.000 ).
Conclusions:. The present study shows that obesity has an effect on gingival health but it has little effect on pocket health and gingival rescission. Obese females reported more gingivitis,gingival recession and pocket depth than male.

The subject of the research is the study of adsorption of pigment dye malachite on to Metal oxide. One of these is metal oxides, cadmium oxide, was chosen as the adsorbents of this dye In the thermal range from 298K to 328K. The study included the test of applying the isotherm models of Langmuir, Freundlich, Elovich and Temkin to the practical adsorption data of the dye under study using the UV spectroscopy. The test results gave linear relations and good correlation coefficients, specifically Temkin and Freundlich .isotherm.
The kinetic data were modeled by using pseudo-first-order, pseudo-second-order, Elovich and intra-particle diffusion kinetics equations, The pseudo-second-order and intra-particle diffusion kinetic model was found to correlate with the experimental data well for the dye.
Adsorption adsorbents were also used to obtain the values of the thermodynamic functions (Free energy ∆G, enthalpy ∆H and ∆S entropy) within the experimental thermal range (328-298K) based on the calculation of the values of the equilibrium constant (Keq). The results indicated that adsorption is endothermic and physical and that entropy increases with increasing temperature and that the reaction is spontaneous in experimental conditions.
