Red spinach (Amaranthus tricolor L.) contains various secondary metabolites that act as antioxidants. These activities can be used to maintain the health of facial skin due negative impact free radicals in form cosmetic preparations peel-off gel mask. This study aims make a mask preparation from red extract meets requirements for physical evaluation preparation. The extraction process was carri...

Visual genes may become inactive in species that inhabit poor light environments, and the function and regulation of opsin components in nocturnal moths are interesting topics. In this study, we cloned the ultraviolet (UV), blue (BL) and long-wavelength-sensitive (LW) opsin genes from the compound eye of the cotton bollworm and then measured their mRNA levels using quantitative real-time PCR. T...

The purpose oi' the study was to investigate, through laboratory tests, the potential for developing fatigue indicators for which some merit was evident from prior research. The response of photographic emulsions, phosphor coatings,and chemical indicator coatings to physical and surface-chemical reactions associated with fatigue damage in 2024-T3 aluminum was investigated. Many indicators were ...

CDOM is the most important sunlight-absorbing dissolved substance in the sea and a critical component of the global carbon cycle. Irradiated CDOM produces reactive species that interact in the ocean in a complex series of photochemical and electron transfer reactions that impact the color and oxidative capacity of surface waters, the growth of marine biota, and the production of volatile gases ...

At synapses formed between dissociated neurons, about half of all synaptic vesicles are refractory to evoked release, forming the so-called "resting pool." Here, we use optical measurements of vesicular pH to study developmental changes in pool partitioning and vesicle cycling in cultured hippocampal slices. Two-photon imaging of a genetically encoded two-color release sensor (ratio-sypHy) allo...

in the present investigation attempts were made for the first time to use the fundamental color stimulus as the input for a fixed optimized neural network match prediction system. four sets of data having different origins (i.e. different substrate, different colorant sets and different dyeing procedures) were used to train and test the performance of the network. the results showed that the us...

Various tests have been done of the STIS using internal wavecals to measure thermal motion of the spectral format on the detectors. In most cases, the spectral format moves less than the speci cation not to exceed 0.2 pixels per hour. Primary causes of the motion are 1) changes to the thermal design dictated by the warmer Aft Shroud environment and 2) on-orbit power cycling of MAMA electronics ...

The rate of the triacylglycerol/fatty acid substrate cycle was measured in vivo in adipose tissue of virgin and lactating rats with pups removed. The rate decreased by 70% in adipose tissue of lactating rats and increased 9-fold on removal of the pups. Similar differences in cycling rate were seen in adipose tissue incubated in vitro in the presence of isoprenaline.

Simultaneous lipolysis and reesterification form the triacylglycerol/fatty acid (TAG/FA) cycle, a substrate cycle commonly used for thermogenesis. Its rate was measured in vivo by indirect calorimetry and continuous infusion of [2-(3)H]glycerol and [1-(14)C]palmitate, after injection of leptin or vehicle saline in rabbits. Leptin stimulated in vivo lipolysis from 9.66 +/- 0.62 to 14.78 +/- 0.93...

Two novel system configurations were proposed for oxy-fuel natural gas turbine systems with integrated steam reforming and CO2 capture and separation. The steam reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel with oxygen as the oxidizer. Internal combustion is used, which allows a very high heat input temperature. Moreover, the turbine...
