Color index

The light-emitting diodes (LEDs) have emerged as a sustainable illumination solution in the lighting industry. However, the commercial LEDs suffer from low chromatic rendition performance. This work proposes a feasible approach to enhance the quality of commercial LED packages via regulating scattering factors.

This paper relies on remote sensing images, collected from Sentinel-2 satellite, to preliminarily map the green space in Da Nang city. The remote sensing data was collected in November 2022. The normalized difference vegetation index (NDVI) is used to recognize the green space pixels. Based on this preliminary study, the area of green space in Da Nang city is approximately 140 km2 , which occupies roughly 56% of the total urban area.

This study was aimed to evaluate the physicochemical properties and chemical profile of seeds oil obtained from new seven sunflower (Helianthus annuus L.) lines as well as their antioxidant and enzyme inhibition activity. The seeds powder was extracted by maceration in n-hexane. The oil content of the seven lines was ranged from 20.04% to 36.65% and was either yellow or pale yellow in color. No significant variations were observed on the refractive index (1.46 unit) of the oil.

In this study, a novel compound is synthesized by adding the red Y2O3:Eu3+ dopant to formal phosphor packages, and used as a component in multi-chip white LED lamps (MCW-LEDs). It was found that this solution can enhance the color rendering index (CRI) of MCW-LEDs that have correlated color temperature (CCT) of 8500 K to the value of more than 86.

Let G be an edge-colored graph. A path in G is a conflict-free path if it contains a color used on exactly one of its edges. The graph G is called conflict-free connected if every two distinct vertices is connected by at least one conflict-free path. The graph G is said to be properly edge colored (properly colored for simplifying), meaning an assignment of colors to edges so that no vertex is incident to two edges of the same color.

Fruit flesh color in watermelon (Citrullus lanatus) is a great index for evaluating the appearance quality and a key contributor influencing consumers’ preferences. But the molecular mechanism of this intricate trait remains largely unknown. Here, the carotenoids and transcriptome dynamics during the fruit development of cultivated watermelon with five different flesh colors were analyzed.

Managing the color uniformity of WLEDs means controlling the size and concentration of ZnO. With the concentration of 10% ZnO, the lumen output of LEDs reaches the highest values. Meanwhile, when the concentration and size of ZnO are 14% and 500 nm respectively, ∆CCT is reduced to the lowest value. Based on the manufacturers' requirements, the most appropriate ZnO concentration and particle size can be determined. However, if requirements include both lumen and color uniformity, the right choice is 14% concentration with 500 nm particle size of ZnO.

In this paper, the rst issue presented and analyzed by several experiments is the in- uence of the distance between phosphor layers in the dual-layer and triple-layer remote package on luminous ux and color rendering property. During the simulation, it was realized that it was possible to create a suitable distance to create higher quality white light-emitting diodes (WLEDs) by adjusting the distance between the phosphor layers.

The protein ki67 (pki67) is a marker of tumor aggressiveness, and its expression has been proven to be useful in the prognostic and predictive evaluation of several types of tumors. To numerically quantify the pki67 presence in cancerous tissue areas, pathologists generally analyze histochemical images to count the number of tumor nuclei marked for pki67.

Rice blast caused by Pyricularia grisea (Cooke) Sacc. became one of the most important disease in rice growing areas of Telangana State because of its wide distribution and destructiveness under favourable conditions. However, sometimes resistant varieties may become ineffective due to evolutionary changes in the pathogen population. Keeping in view the importance of disease, studies were conducted on cultural and morphological variability of P. grisea isolates.
