An interaction between dietary cobalt and selenium was revealed when groups of female weanling rats were fed standard rations, containing different concentrations and ratios of the two trace elements, continuously over a 15 week period. It was found that the levels of selenium in the heart and skeletal muscle were positively related to dietary selenium and negatively related to dietary cobalt, ...

Colonization of the gastrointestinal tract and composition of the microbiota may be influenced by components of the diet, including trace elements. To understand how selenium regulates the intestinal microflora, we used high-throughput sequencing to examine the composition of gut microbiota of mice maintained on selenium-deficient, selenium-sufficient, and selenium-enriched diets. The microbiot...

Abstract Mutual coupling between the multiple antenna designs is a critical problem which deteriorates performance of input output (MIMO) system. It affects efficiency and influences correlation. In this paper, study on isolation elements presented. The antennas are placed cost-effective compact dielectric substrate with different orientations to minimize A CPW fed designed using FR4 substrate,...

The interaction of antimesometrial decidual cells and collagen fibrils was studied by light microscopy and ultrastructural cytochemistry in fed and acutely fasted mice on days 9-11 of pregnancy. Fibrillar elements in the extracellular space consisted of collagen fibrils and filamentous aggregates (disintegrating collagen fibrils). Intracellular vacuoles exhibited typical collagen immersed in el...

The expression of lipoprotein lipase mRNA (LPL mRNA) was studied in rat hearts by use of a sulfur-35-labeled antisense mRNA probe. Rats were studied under three conditions: fed, fasted, and injected with cholera toxin (an irreversible agonist of adenylate cyclase) and then fasted. The highest LPL activity was found in the hearts of cholera toxin-injected, fasted rats. After injection of cholera...

This letter describes a wideband circularly polarized (CP) array antenna with 2 × alignment of sequentially rotated CP patch elements. Each element has diamond-shaped artificial ground structure (DAGS), which extend the 3-dB axial ratio (AR) bandwidth antenna, and elements in are fed relative phases 0°, 90°, 180° 270°. The main purpose this work is to show potential AR by combination DAGS seque...

We present a systematic design method for cylindrical conformal array of rectangular waveguide-fed metasurfaces. The metasurface consists multiple curved waveguides loaded with metamaterial elements—electrically small apertures—inserted into the upper conducting walls waveguides. Each element radiates energy free space to contribute an overall radiation pattern. Thus, geometry or electrical con...

according to high costs of phase shifters in antenna arrays, new methods for beam steering without phase shifter were introduced. frequency diverse array (fda) concept is another approach to beam steering problem. in this structure, the subsequent antenna elements are fed with stepped discrete frequencies causing continuous scanning of space in time. so a range-angle dependent scanning is made ...
