The anthocyanins are water-soluble pigments which facilitates their incorporation into numerous aqueous food systems.
The fruits were harvested at the fully mature stage, then were washed in running tap water and drained.
The prepared samples were incubated at 50°C in a water bath and treated by different extraction time(90–150 min).
As a result, extraction time (X1; min), ethanol concentration (X2; %, v/v ethanol/water) and solvent to solid ratio (X3; mL/g) were selected to be optimized for the extraction of blackcurrant anthocyanins and extraction yield (Y) was taken as the response of the design experiments.

However, because of the large number of sensors, the system is relatively large and expensive, and the preparation process is complex requiring professional support.
To analyze and judge the signal’s characteristics requires for SlimScarf a suitable signal recognition mechanism Signals acquired from experiment respectively are chewing signal (Chewing gum), liquid-food-swallowing signal (swallow water), solid-food-swallowing signal (swallow bread) and sound signal(read book).
Solid food may be accompanied by liquid such as water or saliva.

As a result, soil, surface water, underground water and atmosphere in the contaminated sites have seriously threatened human health and ecological environmental safety.
Health risk assessment for contaminated sites refers to analyzing the main exposure pathway of human to pollutants in soil and underground water in the contaminated sites and assessing carcinogenic risk or hazard quotient of these pollutants to human health on the basis of site environment investigation [5].
Sampling and analysis On the basis of the investigation and analysis on the previous production history, raw materials, products, production process and pollution prevention and renovation measures regarding this site, a professional judgment method is adopted to set sampling points of maximum likelihood and representativeness for collecting topsoil samples and deep soil samples.

Furthermore, the lotus (Nelumbo nucifera) leaf is well known for its inherent self-cleaning property due to having extremely high water-repelling capacity and superhydrophobicity.
A combination of micro/nanoscale structure and low surface energy material (epicuticular wax crystals) contribute to the excellent self-cleaning and superhydrophobic behavior of lotus leaf, where such surfaces exhibit high water contact angle (> 150°) and low sliding angle (< 10°) [5].
Superhydrophobic surfaces (water contact angle >150°) tend to resist bacterial cell attachment [6].
The processed general writing language (.GWL) file was then transferred to a Photonic Professional GT (Nanoscribe GmbH, Germany) for printing of 3D nano-/microstructures.
The materials were fixed using 4% paraformaldehyde for 30 mins and dehydrated by immersing the samples in ethanol and water mixtures with increasing concentrations (50%, 60%, 70%, 80% and 99.8%), and then dried using different parts of ethanol and hexamethyldisilazane (HMDS) solution starting from (2:1), (1:2) and pure HMDS in a fume hood.

These are always artificial aggregates produced within the ironmaking or steelmaking process, or in the production of nonferrous metals Such metallurgical by-products tend to be termed ‘slags’ not just by laymen but even by the professional public.
Granulated slag is blast furnace slag composed mainly of grains below 5 mm in size, with deep open pore, produced by rapid cooling of molten waste by quenching with pressure water; its use in roadbuilding is rare.
Free lime converts to portlandite Ca(OH)2 in the presence of water (Fig. 1).
The volume changes of water saturated samples tested at the temperature of 75°C amounted to 27.4% after 122 days for the samples compacted by 100% Proctor Standard energy, and 43.1% after 188 days for the sample compacted by Proctor Modified energy.

First of all, it is to talk about submersible pump in which both of the media of the volute inside and outside are water.
Critical situation of total reflection exists in the water-volute plate interface.
(3) pi is incident sound pressure; pt is sound pressure of transmitted waves; f is the frequency of sound waves; D is volute thickness; Z is the impedance. ρ1 and ρ2 are density of water and volute plate respectively, ρ1 = 1000kg/m3, ρ2 = 7850kg/m3.

Communication failures in surgery are often underpinned by the inherent differences in professional practice across disciplines.
A high pressure water jet cleaner was used to remove any residual paint and to neutralize the carbon on the surface area of the cylinder head.
