Polyagglutinability of red blood cells is a rare immunological phenomenon, it is due to a cryptic antigen that is abnormally present on the surface of red blood cells. The aim of our work is to shed light on polyagglutinability, which is still poorly understood cause of discordance between the cell and serum tests and can sometimes have harmful transfusion consequences.

In this study, the effects of LED light wavelengths blue and red on both photosynthetic performance and morphology of Gerbera jamesonii plantlets was investigated. The results showed the photosynthesis efficiency via the photo-pigment system and mediated regulation of rubisco activase encoding gene (RCA) mechanism was significantly enhanced by blue light.

We report on the achievement of high-efficiency green, yellow, and red InGaN/AlGaN dot-in-a-wire nanowire light-emitting diodes grown on Si(111) by molecular beam epitaxy. The peak emission wavelengths were altered by varying the growth conditions, including the substrate temperature, and In/ Ga flux ratio.

Color perception is important for fish to survive and reproduce in nature. Visual pigments in the retinal photoreceptor cells are responsible for receiving light stimuli, but the function of the pigments in vivo has not been directly investigated in many animals due to the lack of color-blind lines and appropriate color-perception tests.

The synthesis of fluorescent carbon quantum dots (CQDs) and their applications have attracted great attention due to their excellent properties. Especially, the unique visible-light absorption and photo-induced electron transfer properties make CQDs available in photocatalytic degradation of organic dye pollutants in water resources. Herein, we synthesized nondoped CQDs and boron-doped CQDs (B-CQDs) by hydrothermal method and compared their photocatalytic degradation activity of methylene blue (MB) and methyl red (MR) dyes under visible light irradiation.

Infrared spectral analysis of milk is cheap, fast, and accurate. Infrared light interacts with chemical bonds present inside the milk, which means that Fourier transform infrared milk spectra are a reflection of the chemical composition of milk. Heritability of Fourier transform infrared milk spectra has been analysed previously.

Effects of red Y2O3:EU3+ phosphor in silicone lens on the color rendering ability of white led lamps
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.

This paper applied an ordered probit model to investigate factors associated with RLR using questionnaire data collected in Hanoi. Generally, this paper found that males and motorcyclists have a higher likelihood of RLR than females and car drivers. In addition, the younger and lower-income road users and the ones who are businessmen and who have a commuting trip in off-peak hours are more likely to run the red light.

In the present study, ZnO nanostructures were ultrasonically synthesized and immobilized on the surface of diatomite and used for visible light photocatalysis of Acid Red 88 (AR88) in the aqueous phase. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses were employed for characterization of the samples. The process was optimized via response surface methodology (RSM) on the basis of central composite design (CCD).

The average correlated color temperature analysis indicates that the Y2MoO6:Pr3þ NPs can be useful for use in warm light sources. The Y2MoO6: Pr3þ (5 mol%) NPs were used for the design of anti-counterfeiting ink in security applications. The tunable properties of the prepared Y2MoO6:Pr3þ NPs make them suitable for multifunctional applications.

The solution of paracetamol and sildenafil (Penagra) was effectively sensed using modified carbon paste electrodes. LNPs showed a good photocatalytic activity (PCA) for Orange Red (OR) dye under UV light irradiation. These results indicate that the synthesized LNPs are a good candidate for displays, waste water treatment and for the use as electrochemical sensors.

The nanocomposites exhibit a flower-like morphology with the required elemental composition of Ba, W, O, Mo and S. The photocatalytic activity of the BaWO4eMoS2 nanocomposites (75 mg) for dye (20 mM) removal is 95% upon a solar light exposure in 80 min. The photocatalytic reactions were found to obey the pseudo-first-order kinetics according to the LangmuireHinshelwood model.

Vertebrates use different pigmentation strategies to adapt to various environments. A large amount of research has been done on disclosing the mechanisms of pigmentation strategies in vertebrates either under light, or, living in constant darkness. However, less attention has been paid to non-obligate, darkness dwellers. Red-spotted toothed toads Oreolalax rhodostigmatus (Megophryidae; Anura) from the karst mountainous region of southwestern China are non-obligate cave dwellers.
