honey has antibacterial activity. the aim of this study was to evaluate the antibacterial activity of honey on streptococcus mutans and lactobacillus.in this in vitro study, solutions containing 0%, 5%, 10%, 20%, 50% and 100%(w/v) of natural hamadan honey were prepared. each blood (nutrient) agar plate was then filled with dilutions of the honey. the strains of bacteria were inoculated in blood...

OBJECTIVES The aim of this study was to investigate the effect of manuka honey, artificial honey and an antibacterial component (methylglyoxal) on cell division in methicillin-resistant Staphylococcus aureus (MRSA). METHODS Viability of epidemic MRSA-15 NCTC 13142 incubated with manuka honey, artificial honey and methylglyoxal was determined, and structural effects monitored by electron micro...

abstractin this work, the micro powder was the product of cedar leaf (mpcl) is used as a low-cost adsorbent for the removal of pb2+ ions from aqueous solutions. bath experiments were used to determine the best adsorption conditions the adsorption percentage of pb2+ ions mpcl samples at different initial ph, contact time (tc), adsorbent dosage and temperature (t) were investigated. effective rem...

The extensive mortality of yellow-cedar along more than 1000 kilometers of the northern Pacific coast of North America serves as a leading example of climate effects on a forest tree species. In this article, we document our approaches to resolving the causes of tree death, which we explain as a cascade of interacting topographic, forest-structure, and microclimate factors that act on a unique ...

Fantastic Realism is a genre which remind us of Russia and its great writer Dostoevsky. This genre has been developed in Iran among Iranian writers who have been familiar with the books of world literature, especially Russian literature. Fantastic Realism employs and combines reality and imagination, and while it concerns the reality related to human beings, it pictures that kind of reality whi...

The conjugate gradient method is a powerful algorithm to solve well-structured sparse linear systems that arise from partial diierential equations. We consider here three diierent conjugate gradient schemes for solving elliptic partial diierential equations that arise from 5-point diierence schemes: the classical CG, CG with a block diagonal-block incomplete Cholesky preconditioner and the redu...

honey is a by-product of flower nectar and the upper aero-digestive tract of the honey bee, which is concentrated through a dehydration process inside the bee hive. honey has a very complex chemical composition that varies depending on the botanical source. it has been used both as food and medicine since ancient times. human use of honey is traced to some 8000 years ago as depicted by stone ag...
