This study reveals through the investigation in the orations of Holy Continent Imam Ali (pbh)that Antithesis and Collection are two Rhetoric sciences of art are clear in the systematical oration of the Nahj Al-Balagha Book occupying widely range of the orations as they are intervened and adjacent in most texts with each their intersection with other Rhetoric sciences of art are clear in the systematical oration of the Nahj AKL-Balagha Book

Magnesium Phthalocyanine (abbreviated MgPc) like other methallophthalocyanines have limited solubility in most solvents this behavior prevented complete spectroscopic studies. In this paper MgPc was prepared and Infra-red peaks were characterized, and MgPc has been found to be soluble in several solvent (DMF, DMSO, THE, Pyridine and Chlorobenzene). The study show that the position of Q-band show very small change in non aromatic solvent DMF, DMSO and THF. The blue shift was observed in aromatic solvent (chlorobenzene) this is because of the aggregation of MgPc molecules and the aggregation increase as the concentration increase. In pyridine a red shift of Q-band was observed.

Investigation of antibacterial activity of flavonoides extract of lawsonia inermis leaves was carried out on gram positive and gram negative pathogenic bacteria , the results exhibited a variable susceptibilities of microorganism for different concentration of flavonoides extract (6.25 ,12.5 ,25 ,50 ,100 mg/ml). The activity of this extract was associated with high concentration (100 mg/ml) using plate methods flavonoides extract of L. inermis had the highest effect and wide diameter of growth inhibition zone agiants Streptococcus sp. And it has no effect of growth of Burkholderia pseudomallei and Staphylococcus aureus was noticed except at very high concentration.

Numerical model for the distribution of laser intensity through lenses exhibiting spherical aberration is proposed. The diffraction integral equation is modified for the case of CO2 laser in a gas discharge plasma. A multiple distinct collinear regions of intense ionization along the optic axis near the lens focus with equidistance separations are observed, and the distance between them is measured. The results are compared with some available experimental data, and the comparison shows a good agreement between them.

Otitis media with effusion (OME) is a common problem especially in children and if not diagnosed early and treated appropriately may lead to serious complications.
Our study was conducted to assess the audiological changes associated with OME regarding the type, intensity and each frequency affected. The study involved 50 patients with age range from 4-15 years old. The average of air conduction thresholds in the submitted cases (conductive deafness) were 31dBHL in the range between (0-50) dBHL. 500Hz is the most frequency affected and the least affected one is 2000Hz. In bone conduction thresholds (sensor neural hearing loss), we found that the frequency 1000Hz is the most affected one, while the frequency 250Hz is the least affected.

In this study we test the effect of magnetic field on the corrosion of Iron in NaCl – solution of different ratios. The samples of Iron were put in the NaCl-solution of different ratios of concentration ranged between (1% , 2% , 3% , 4% and 5%). The magnetic field effect on the hydrogen reduction and on the activation –controlled iron dissolution reaction .Results show that the magnetic field effect on the corrosion of Iron in the NaCl-solutions and increased the corrosion. See the figures(1-7) that represent the corrosion of iron in NaCl-solutions with applying magnetic field and without magnetic field. In control group fig(1), we show the highest loss in weight while in magnetic field group fig(2), we show the lowest weight loss. This can be ascribe to effect of magnetic field on the reduction and oxidation reactions of corrosion.

This study aims to finding out the reasons of pupils' weakness in compassion at primary stage according to their teachers' opinion.
This research applicator upon compassion teachers of the academic year (2009 - 2010), the research sample consist of (100) teachers of primary stage, of first, the research processed exploratory study consisted of the following question: what is reasons which lead to the weakness of pupils in compassion.
Was offered to exploratory sample consisted of (50) teachers, than the researcher processed the find study which was formed according to the teachers

During the present study, three apple varieties were injured In vitro to facilitate a route for fungi to attack apple samples. The present study revealed that, most number of fungi was 10 species recorded by yellow apple variety, and the lowest was 5 fungal species isolated from red apple variety, whereas 6 fungal species recorded in green apple variety.
The most appearance percentage was 100% recorded by Penicillium expansum in all varieties, and the most abundant fungi genera associated with yellow apple are Aspergillus, Penicillium, Alternaria, Monilinia and Cladosporium.whereas the fungi genera which were isolated from red apple variety belong to Aspergillus, Penicillium, Cladosporium and Monilinia.
Three genera of fungi were isolated from Green apple variety which was
Aspergillus, Penicillium and Fusarium.

Ninety-eight samples were collected from some primary schools children in misan. This study included 20 schools (10 males, 10 females).Fifty eight samples from males and forty samples from females. Samples were collected from (Hair, skin, nail and foot). Ten species belong to three genera were isolated and identified the fungi included: Six species from the genus Trichophyton, three species from the genus Microsporum and one species from genus Epidermophyton.
The antifungal susceptiblity test for 10 fungal isolated against some antifungal drugs using well diffusion method was done, in vitro where all the isolates showed a high sensitivity against clotrimazole (100 %) than other antifungal (fluconazole and nystatin

In this research certain properties for pare to distribution with two parameters had been proved, to achieve the main propose of research, which is the comparison between Bays method and classical methods to estimate the shape parameter using simulation.
Monte-carlo methods for different models the comparison between standard Bays estimator and other estimators have been done using MSE (Mean square error) and MAPE (Mean absolute percentage error) assuming different values for sample size and for scale parameter is known.
The experimental aspect and results of simulation experiments and analysis of the results are explained in tables.

In this present paper, experimental results on fire retardant efficacy of low-density polyethylene added with various contents ratio of sun flower plant as a filler agent were reported .The ratio of doping was 5,10,20,30,40 and 50 Of weight where the size of sun flower particles used in this research was (<425) micrometer .Several parameters were studied like average of burning time , burning rate and percentage of burning rate .The obtained results showed that sun flower as a suitable additive to low density polyethylene and the increase of doping ratio leads to decrease in average of burning time at doping ratio (10%-50 %) where this behavior is opposite to the 5% ratio hence there is an increase in time of burning . A similar results were obtained when calculating burning rate .Also the percentage of burning time has two values positive for doping ratio equal or much than 10% while negative value was found at doing ratio 5% relatively to it’s pure value where negative sign explaining the mode of burning resistance of low density polyethylene.

The study has done for assessment of the activity for aqeous, Organic Solvents (alcoholic and hexane extract) and the Secondary compound alkaloids and flavonoids for an algae Chara sp. Against the fourth larval in star of Culex quinquefasciatus.
The result showed different activity for the used extracts in larvae killing hexane has the strongest effect with LC50 and LC90 reached for 1000, 3000 part per million (ppm) after 24 h from the treatment respectively with mortality rate 65.27% , then 1000, 4000 ppm for alcoholic extracts and 1000, 6000 ppm for alkaloids after 48h with mortality rate 62.1% and 54.70% finally, aqeous and flavonoid extracts were the least effects among the used extracts with mortality rate 4.16% and 36.1% respectively
