Abstract Background Nowadays, light-emitting diodes (LEDs) as a new lighting technology, have been emerged an alternative source of light for plants due to their wavelength specificity, the narrow width bands, small size, solid structure, long lifetime, and low heat generation. Here we investigated effect different LED sources on essential oil components antioxidant activity Melissa officinalis...

PURPOSE To evaluate the risk factors for pterygium in the dry, high altitude province of Ilam, Iran. METHODS The study included patients who presented to ophthalmology clinic. The patients were divided into two groups: 210 diagnosed with pterygium or pinguecula (unilateral or bilateral), and 210 healthy controls. Demographic variables, living environment, disease type, disease laterality, fam...

a key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. so, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. the x-ray diffraction patterns indicated that exfoliated ty...

Reservoir modeling is the process of generating numerical representations of reservoir conditions and properties on the basis of geological, geophysical, and engineering data measured on the Earth’s surface or in depth at a limited number of borehole locations. Therefore, reservoir modeling requires an incorporation of the data from a variety of sources, along with an integration of knowledge a...
