Herbal remedies are used in induction of lactation. In view of that .Borage Officinalis was employed to ensure an abundant milk supply or rectify milk insufficiency .However, this remedy has not been scientifically tested .The animals were treated with the aqueous extract of Borage Officinalis flowers at a daily concentration of 100 mg / kg body weight /ml for each rat through Oro-gastric tube for 14 days. Animals were subdivided into subgroups according to their physiological status. Mammary glands of these animals were processed for histological, histochemical and immunohistochemical studies. Parameters indicated that the aqueous extract of Borage Officinalis flowers induced lactogenesis in the mammmary glands of virgin and pregnant rats

      Using three-point bending experiments,  the effect of the particle size of SiO₂ on the flexural properties of epoxy composites was investigated. Young modulus and flexural strength were studied for different weight percentage of filler  (2,4,6,8 and 10) wt%.The size of SiO₂ particles varied from micro (100um) to nano (12nm) .

Flexural strength and  Young modul were found to increase with the filler content, but when the particle size decreased to the nanoscale, the  Young module  increased. Flexural strength was higher for microcomposites than nanocomposites.

Vibrio cholerae enterotoxin was extracted by cooling centrifugation and filtration
with milipore filter (0.22um) and was purified by using Sephacryl –S- 6 gel
filtration,the content of protein was estimated . The results showed protein
concentration was 28.5 microgram/ml,the present of enterotoxin was detected by
infant suckling mouse method.
.The cytopathic effect of enterotoxin was studied by injecting a number of mice with
purified enterotoxin, It was found caused shortening the villi of the intestine at
concentration 55 and 45 ug /ml of purified enterotoxin, while the effect on liver
showed degenerative change with necrosis at 55 ug/ml of enterotoxin and caused
necrosis and infiltration of inflammatory ce

Abstract

The current research aims to examine the effect of the Adi and Shayer model on the achievement of fifth-grade students and their attitudes toward history. To achieve the research objective, the researcher has adopted two null hypotheses. 1) there is no statistically significant difference at the level of (0.05) between the average score of students of the experimental group who study the history of Europe and modern American history according to the model of Addie and Shayer, and the average scores of the students of the control group who study the same subjects according to the traditional method in the test of post-achievement. 2) There was no statistically significant difference at the level (

Staphylococcus lugdunensis, isolation between 12.5 to 1.8% routine works may be a possible peroral route of infective endocarditis and found in the oral cavity by examined using saliva. Similar supragingival plaque isolation was observed. The increased bacteria resistance to antibiotics multiple have led to novel methods for resistance bacteria; antimicrobial agents are well known (ZnO NPs) by biological method and are lower toxicity and biology safety ZnNOPs activity by plant extraction and less toxicity as well as bio-safe. The nanoparticle was synthesized by biological method (Green) by barberry (Berberis vulgaris) extract. In this study using (WAD) method using different concentrations between (128, 64, 32, and 16) mg/mL of ZnO NPs, The

  A dynamic experimental study of thermal decomposition of low density polyethylene has been carried out with two different heating rates  .As usual , we can determine the activation energy of any polymer using( 3 - 6 ) TGA experiment as minimum , but  in  this work , we estimate the activation energy of  LDPE  using two of  TGA  experiments only

Experimental densities, viscosities η, and refractive indices n_D data of the ternary  ethanol+ n-hexane + 3-methyl pentane system have been determined at temperatures 293.15,303.15 and 313.15 K and at atmospheric pressure then these properties were calculated theoretically by using mixing rules for densities, viscosities and refractive indices .After that the theoretical data and the experimental data were compared due to the high relative errors in viscosities an equation of viscosity was proposed to decrease the relative errors.
