We consider extremal graph-theoretic problems on regular structures. The problems ask to maximize a certain parameter of the structures in question under the condition that the values of some other parameter(s) are constant. This is where the term isoparametric is taken from. The graph problems we consider are edge-isoperimetric problems, and the poset problems are dealing with the notion of Ma...

Let $R$ be a commutative ring with nonzero identity and let $M$ unitary $R$-module. The essential graph of $M$, denoted by $EG(M)$ is simple undirected whose vertex set $Z(M)\setminus {\rm Ann}_R(M)$ two distinct vertices $x$ $y$ are adjacent if only ${\rm Ann}_{M}(xy)$ an submodule $M$. $r({\rm Ann}_R(M))\not={\rm Ann}_R(M)$. It shown that connected diam}(EG(M))\leq 2$. Whenever Noetherian, it...

The aim of this study was to investigate the effects of a 12-week rehabilitation program on body composition, shoulder pain, and isokinetic internal/external torques of pitchers with impingement syndrome. A total of 30 pitchers were divided into 2 groups: experimental group (EG, n = 16) and control group (CG, n= 14). The rehabilitation program consisted of physical therapy, warm-up, work-out, a...

Embryonic germ (EG) cells derived from primordial germ cells are undifferentiated and pluripotent stem cells. In our study, primordial germ cells isolated from the genital ridges of Beijing duck (Anas domestica) embryo at stage 28 were co-cultured with mice embryonic fibroblasts. Duck EG cells grew with a high nuclear:cytoplasm ratio and were positive for periodic acid-Schiff and alkaline phosp...

Objectives: The objective is to see the effectiveness of hydrocortisone (HC)-ethanol gel (EG) ointment in treating children with Moderate-to-severe atopic dermatitis (AD). Methods: Thirty moderate-to-severe AD participated a 2-week double-blind, randomized, and controlled clinical trial. They were randomly assigned apply either an 1% HC or novel containing dispersed EG droplets HC. At end 2 wee...

Ethylene glycol (EG)-based lubricant was prepared with dissolved organosolv lignin from birch wood (BL) and softwood (SL) biomass. The effects of different lignin types on the rheological, thermal, and tribological properties of the lignin/EG lubricants were comprehensively investigated by various characterization techniques. Dissolving organosolv lignin in EG results in outstanding lubricating...

Polyvinyl alcohol (PVA) nanofibers encapsulating eugenol (EG)/cyclodextrin (CD) inclusion complexes (IC) (EG/CD-IC) were produced via electrospinning technique in order to achieve high thermal stability and slow release of EG. In order to find out the most favorable CD type for the stabilization of EG, three types of native cyclodextrins (α-CD, β-CD, and γ-CD) were used for the formation of EG/...

Several studies have suggested that olfactory ensheathing glia (EG) can form Schwann cell (SC)-like myelin. Because of possible misinterpretation attributable to contaminating SCs, the capacity of EG to produce myelin needs to be explored further. Therefore, we compared the abilities of adult EG, purified by immunopanning with p75 antibody, and adult SCs to produce myelin when cocultured with p...

OBJECTIVE The objectives of this study were to analyze efficacy of immature and mature mouse oocytes after vitrification and warming by applying various combinations of cryoprotectants (CPAs) and/or super-rapid cooling using slush nitrogen (SN(2)). METHODS Four-week old ICR female mice were superovulated for GV- and MII-stage oocytes. Experimental groups were divided into two groups. Ethylene...

We report photoresponse measurements from two comparable epitaxial graphene (EG) devices of different thicknesses (2-layer vs. 10-layer EG) made on SiC substrates. An asymmetric metal contact scheme was used in a planar configuration to form a Ti/EG/Pd junction. By moving the laser illumination across the junction, we observed an increased photocurrent signal resulting from local enhancement of...
