The interaction of 2, 3-butadione monooxime (B) with phenol and its five substituents in n-heptane are studied by using uv spectroscopy. The study lead to the formation of mono-protonated, bi-protonated as well as intramolecular hydrogen bonding species. The later are found to be of the type O − H∙∙∙∙N and O − H∙∙∙∙O. The process of hydrogen bond formation is confirmed here from uv spectra and the calculated thermodynamic parameters. This shows that ∆H and ∆S have a negative signs, in addition to their values which support hydrogen bond formation.

Out of 50 samples obtained from humans of different environments, 18 were diagnosed as Staphylococcus aureus. 6 out of these diagnosed isolates were tested for elimination of resistance to antibiotics by chloroform and acetone extracts of the plant Olivera dicumbens.
Bacterial isolates were treated with subminimum inhibitory concentrations (sub-MIC) of the above mentioned extracts. Percentage of loss of resistance of colonies to antibiotics was measured. Chloroform extract at the concentration 250 mg/ml was found to be the most effective concentration inducing resistance of this bacteria to the antibiotic Ciprofloxacin. Highest percentage loss of resistance (38%) was found in the 5th isolate. For loss of resistance to the antibiotic Ampicillin, highest resistance (36%) was found in the 6th isolate. On the other hand, the least loss of resistance was found against the antibiotic Nalidixic acid in the 5th isolate. No clear effect was obtained with the acetone extract. It can, therefore, be concluded that the chloroform extract may have acted as mutagenic, eliminating the resistance of certain Staphylococcus aureus isolates to some antibiotics.

The effect of substitution of the ion instead of La+3 in the superconductor was studied, an increase in electrostatic potential energy E. P. (E) with increase of Sr % was noticed, and a step change in P. E. when Sr is added is noticed indicating a phase change occurrence in the crystal structure .Increase of Tc, with the increase of Sr, noticed earlier, is linked with increase of E.P. and a relation between E.P. and Tc is found , the increase of Tc is due the creation of holes by valance difference between La & Sr, which also leads to collapse of crystal by reduction of repulsion between Sr & Cu atoms this have the same effect as the application of pressure on the crystal, which increases Tc also. For x >0.15, Tc decreases due to the appearance of vacancies which may have screening effect of the electrostatic field.

The present study carried out to investigate the injuries of radio frequency on the nonsensory components (lens, cornea, choroid, iris, sclera and optic nerve) of two species of teleost fishes which were Chalcalburnus mussulensis and Noemacheilus angora. The fishes exposed to 80KHz and 1400 volts of radiofrequency for sixty day. The time of exposure was five hours daily. The dissection of samples occurred at thirty day and sixty day.
The results revealed several histophathological changes for each of the above components, but the lesions were more sever in N.angora than C.mussulensis. After thirty day of exposure, different lesions were appeared in the various parts of the two species. The injuries were more sever at sixty day, which generally summarized as: lens cataract, pyknosis of lens capsule in C.mussulensis while in N.angora wide deterioration in lens was appeared which were pyknosis, necrosis and wrinkiling of the whole lens. The lesions of cornea were deterioration of some parts of central cornea epithelium, pyknosis of Bowmans membrane and keratocytes, degradation of Descemet membrane and endothelium. on the other hand necrosis and rarfaction of the stroma occurred: The previous lesions variable in the different regions of eye ball (dorsal, ventral etc.). The injuries were more sever in N.angora. The iris of C.mussulensis degenerate completely in some regions and appeared as a thin dens structure generally. In N.angora the iris dialated in some regions and several mass of melanocytes appeared in all of the area, necrosis of blood capillaries and gauanophore cells also appeared. In some regions the discrete feature of the iris disappeared. The choroid lesious in C.mussulensis appeared as: Necrosis and disruption blood capillaries, bleeding, necrosis rarefaction of the argentum layer, necrosis and shrinkage of choroid gland. In the N.angora most of the choroid was deteriorated. The sclera of the C.mussulensis showed rarefaction and unorganization of collagenous fibers at the central part, pyknosis and thining at the peripheral parts. In the N.angora rarefaction and swallowing of scleral collagenous fibers occurred. The optic nerve of the N.angora showed deterioration and edema in specific region. We could conclude that the low level of radiofrequency induced obvious and variable injuries in the nonsensory components of the eye of two species of fishes. The variation may be due to the species differences.

In this study we focused on adding ferrosilicon and this adding was in form of different ratio and constant size of these additive to the matrix of Iraqi cement (Om Quasar factory for cement). the prepared samples was in form of cubic and evaluated as they were treated different (water treatment, moisture treatment dry treatment). All the prepared samples had a proportion of (3/1 cement to sand) and in the form of cubes with aside (50 mm) long. they also had the weight–rate of the added ferrosilicon to the cement which was (1% - 5%). The obtained results showed that the cement mixture that had the weight rate of 1% at moisture curing is the best as it has good mechanical properties (flexural strength, splitting tensile, compressive strength). These properties have been used to study the resistance of the modified cement to the chemical agents that attack cement and concrete.
