Tap water differs from pure water, it contains more chemical contents arise in drinking water, it effect on health concern only after extended exposure of years, rather than months. The purpose of this article is to study the optical properties of tap water by using different power density from He-Ne laser beam transport through some samples. These samples of water mostly contain NaCl salts and clay .When we increasing concentration and sample length we can observed that decreasing transmittance ,(absorption and extinction) coefficients while the absorbance will be increased .At the 5 cm sample length we observed that tap water has transmittance about 17%, while NaCl (0.7) concentration has 58%,clay solute has 2%, and mixing from (0.7 NaCl and 0.15 clay) concentrations has transmittance 8%, The absorbance and absorption coefficient of tap water is greater than NaCl and less than clay alone and mixing (clay with salt) at the same sample length.

In this study, silver colloidal nanoparticles have been prepared by chemical reduction of silver nitrate by trisodium citrate as a reduction agent. The adding time of the reduction agent was held constant while the time of stirring was varied. The resulting silver nanoparticles were characterized by UV-VIS absorption spectroscopy. The non-linear refractive index and absorption coefficient of silver nanoparticles were investigated using a single beam z-scan technique. The excitation source was a continuous wave (CW) of 532 nm diode laser with a beam power of 40 mW. All investigated samples showed negative and large thermally-induced non-linear refractive indices. Other nonlinear optical parameters (i.e.β,χ_r^((3)),χ_i^((3))) were also calculated. Our measurements confirm that the non-linear parameters are caused by self-defocusing process making them potential candidates for nonlinear optical devices.

This study was carried out to evaluate the antitumor effect of live attenuated measles virus Schwarz (MV) vaccine strain on tumor cell lines in vitro. Live attenuated measles virus Schwarz vaccine strain was obtained from Aventis Pasteur, France. Live attenuated measles virus Schwarz strain was propagated on Vero, human Rhabdomyosarcoma (RD) and human Glioblastoma-Multiform (GBM) cell lines which were supplied by Iraqi Center for Cancer and Medical Genetic Researches (ICCMGR). Results revealed that cell fusion occurred after 24 h of infection. The infected confluent monolayer appeared to be covered with syncytia with granulation and vaculation of cells after 72 to 120 h. Moreover, the formation of large round empty plaque spaces was observed in infected cells. Results of oncolytic cytopathic effect showed that after 120 h of exposure alterations in morphology of Vero, RD and GBM cells. Cells were rounded, shrink, clustered cells and large empty space with cell debris as a result of cell lysis and death. Haemadsorption effect of MV was studied and result recorded that all cell lines infected with virus have the ability for haemadsorption human red blood cells after 72 h of infection. While uninfected cells gave negative results. Detection of MV H protein by monoclonal antibodies in infected cells of all cell lines by immunocytochemistry assay gave positive results (brown color) in cytoplasm of infected cells. Cell viability was measured after 72 h of infection by MTT assay. Results showed a significant cytotoxic effect for measles virus (P ≤0.05) on growth of RD and GBM cell lines at the first dilution and the second one after 72 h of infection. When the dilution increases, there was a significant decline in the inhibitory effect with a significant cytotoxic effect as compared with the control. Also, concentrated inoculums of measles virus showed a significant cytotoxic effect when compared with the control.

In this work a standoff Raman spectroscopy SRS system has been designed, assembled andtested for detecting explosives (Ammonium nitrate, Trinitrotoluene and Urea nitrate) in darklaboratory at 4 m target-telescope distance. The SRS system employs frequency doubled Nd:YAGlaser at 532 nm excitation with laser power of 250 mW and integration time of 2 second. The Cassegrain telescope was coupled to the Ventana Raman spectrometer using a fiber optics cable, and Notch filter is used to reject Rayleigh scattering light. The Raman scattered light is collected by a telescope and then transferred via fiber optic to spectrometer and finally directed into charge coupled device CCD detector. In order to test SRS system, it has been used to detect the Raman spectra of Toxic Industrial Compounds TIC such as acetone, toluene, and carbon tetrachloride. The SRS results were compared with conventional Raman microscopy results using a bench top Bruker SENTERRA Raman instrument.

Lipopolysaccharide was extracted from invasive local isolate Klebsiella pneumonia previously isolated from neonate blood samples. LPS was extracted by phenol hot water method and partial purified by gel filtration chromatography on sepharose CL-6B gel. The results showed that the percentage of carbohydrate amount in the partially purified LPS extract was 9.5% while the percentage of protein in the same extract was 0.06% with no nucleic acids. Intravenous administration of (0.1and1)μg/kg of partial purified LPS in the rabbit led to increase body temperature in dose dependent manner (38.8° and 40.2°)C respectively. Intraperitonial administration with the dose 10μg/mouse cause an increasein serum cytokine (IL-1α, IL-6 and TNFα) level after 4 hr of the injection. Conclusion: LPS extracted from pathogenic isolate of K.pneumoniae with high purity, has immunomodulator effect by increasing serum cytokine (IL-6 & IL-1α) level which play a role in the elevation of body temperature, and TNFα after 4hr of intraperitonial administration of LPS.

In this study, the effects of three insecticides including: Fenvalerate, Thiacloprid and Fenoxycarb on egg parasitoid, Trichogramma evanescens were investigated. The toxicity of insecticide were tested using two laboratory tests: (a) direct spray on Ephestia cautella eggs containing the parasitoid for effects on parasitism and emergence of the adult parasitoids (b) adult parasitoid exposure to dry insecticide films residue in glass vials. All insecticides were prepared according to the manufacturer’s recommendations for field application. Results showed that these insecticides varied in toxicity and have different degrees of effect regarding the emergence and parasitism of the parasitoid. Fenoxycarb was non-toxic or low toxic to T. evanescen and did not affect immature stages development and adult emergence. Whereas, Fenvalerate was highly noxious to the parasitoid and significantly reduced the percentage of emergence and parasitism of T. evanescens developing in host eggs. The effects of Thiacloprid were slightly toxic to T. evanescens as it fell into the class 2 when parasitoids were directly exposed to chemical residues. While, Fenvalerate classified as moderately toxic and caused higher mortality than Fenoxycarb and Thiacloprid in both glass surface residues and direct spray of host eggs. Therefore, obtained data provided useful data for implementing both chemical and biological control strategies in integrated pest management.

Fourth gathering, nine indicators were presented to various force 1, 5 and 10 mW of He-Ne laser at various circumstances 5, 10 and 15 min (laser). The optical properties were considered with bright unmistakable UV-visible and FTIR spectroscopic. In addition, the optical vitality band cavity and carbons number was computed at various gamma measurements and diverse time's introduction of He-Ne laser. The outcomes for second, third, fourth and fifth gatherings demonstrate expanding in the absorbance with expanding in the time presentation of He-Ne laser and gamma dose. The FTIR spectrum indicate moving in the groups of CR-39 track indicator presented to gamma beam, laser and (γ +laser), for gamma beam demonstrate expanding in the absorbance at 300 kGy and unsymmetrical diminishing of absorbance at 500-1600 kGy, and for CR-39 identifier presented to (γ +laser), the impacts demonstrate unsymmetrical diminishing in the force absorbance with increment in the gamma measurements, at laser impacts indicate expanding in the absorbance A, with expanding in the time introduction of He-Ne laser at various forces.
