Objective(s): Iranian researchers have enriched conventional engine oil with nanoparticles at the Institute of Petroleum Research and hope that this product can replace conventional engine oil due to the improved effects of copper nanoparticles on oils. the purpose of this study was to investigate the pathological effect of engine oil enriched with copper nanoparticles on the rat.Methods:...

Mafic rocks including basalts and gabbros are the main constituents of Birjand ophiolites. They are found in several places and show low grade metamorphism in the field and under the microscope. Chondrite-normalized REE patterns for basalts and gabbros indicate that these rocks are transitional-enriched to depleted mid-oceanic ridge basalts respectively. Otherwise, N-MORB normalized trace eleme...

The theory of enriched accessible categories over a suitable base category V is developed. It is proved that these enriched accessible categories coincide with the categories of flat functors, but also with the categories of models of enriched sketches. A particular attention is devoted to enriched locally presentable categories and enriched functors.

Isosurface extraction is a standard method for visualizing scalar volume data that can be used to render a specific material boundaries inherent in multi-material data sets. Multiple transparent isosurfaces can thus be used to visualize multiple material boundaries, but still fail to capture any data in between the boundary layers. We describe how isosurfaces can be “enriched” with surrounding ...

[18f]kf, considered as a reference standard for positron emission tomography of the skeletal system, was produced by the bombardment of enriched water ([18o]h2o>95%) with high energy protons in nrcam cyclotron. after the extraction of fluoride from enriched water as kf, and passing it through microbial filter and fine adjustment of acidity and osmolality, it was converted into an injectable for...

We develop a homotopy theory of categories enriched in a monoidal model category V. In particular, we deal with homotopy weighted limits and colimits, and homotopy local presentability. The main result, which was known for simplicially-enriched categories, links homotopy locally presentable V-categories with combinatorial model V-categories, in the case where all objects of V are cofibrant.

The model checking problem for open systems has been widely studied in the literature, for both finite–state (module checking) and infinite–state (pushdown module checking) systems, with respect to CTL and CTL. In this paper, we further investigate this problem with respect to the μ-calculus enriched with nominals and graded modalities (hybrid graded μ-calculus), in both the finite–state and in...

As with traditional feed grains, the form in which flax seed is fed impacts egg production and hen performance (Choi et al. 1986, Vilarino et al. 1996). Flax seed form also affects the amount of omega-3 polyunsaturated fatty acid (PUFA) incorporated into the egg. Differences in the omega-3 content of eggs from laying hens fed whole versus milled flax seed have been reported, with many researche...
