Telang flower is a plant that has health effect on the body. 10% telang can be used as natural food coloring. Steamed cake also traditional favored by community. usually uses synthetic coloring to attract consumers. This study aimed examine antioxidant capacity, chemical characteristics, and organoleptic properties of steamed with addition extract petals flower. research using experimental appr...

In senescing carnation (Dianthus caryophyllus L.) flowers, ethylene is produced from the gynoecium, and acts as a diffusible signal received by petals to induce the expression of 1-aminocyclopropane-1-carboxylate (ACC) synthase (DC-ACS1) and ACC oxidase (DC-ACO1) genes in the petals. This results in autocatalytic ethylene production in the petals. We investigated ethylene production in cut flow...

By combining a spiral zone plate (SZP) and grating, we propose single optical element, termed composited grating (CSZPG), to generate flower mode vortices with the equicohesive petals has long focal depths. Theoretical analysis reveals that CSZPG can approximately petals, it longer depths compared conventional SZP. Moreover, performance of on period, length radius is investigated. The experimen...

A sunflower with p petals consists of sets whose pairwise intersections are identical. The goal the problem is to find smallest r=r(p,k) such that any family rk distinct k-element contains a petals. Building upon breakthrough Alweiss, Lovett, Wu and Zhang from 2019, Rao proved r=O(plog(pk)) suffices; this bound was reproved by Tao in 2020. In short note we record r=O(plogk) suffices, using mino...

A sunflower with $r$ petals is a collection of sets so that the intersection each pair equal to all them. Erd?s and Rado proved lemma: for any fixed $r$, family size $w$, at least about $w^w$ sets, must contain petals. The famous conjecture states bound on number can be improved $c^w$ some constant $c$. In this paper, we improve $\mathrm{log}\ w)^w$. fact, prove result robust notion sunflowers,...

Angular distribution of light diffracted out of the plane of two-dimensional photonic crystals (PhC) has been studied in the azimuthal direction with a specially designed waveguide structure. The optical images of the light extraction patterns from the guided photoluminescence light are obtained with laser excitation in the center of the annual structure made on GaN multilayer. For increasing l...
