The susceptibilities of chips of a dacite, an andesite and a spilite (altered basalt) are also experimentally investigated for a range of chip sizes from a few mm down to 200 μm. The relationship is quite flat until very small grain sizes are reached where the susceptibility either ...
A waveform’s period is the most basic measurement. It is the time duration on a single cycle of a periodic waveform shown as parameter P1 in the figure. The oscilloscope measures period by measuring the time between waveform crossings of a fixed threshold voltage for waveform segments with the...
Depending on the amount of baking you plan to do, there are several options for buying bags of chocolate chips. For very small quantities that might need to be melted down, choose a bar of baker's chocolate. Chocolate chips are made to withstand the heat of an oven and have a higher s...
The Raman peak intensity of gallic acid in plastic bags is the highest, and the vibration spectrum can be clearly distinguished. The signal intensity of gallic acid in plastic bottles and glass bottles is weaker, and the peak intensity at 114.7 cm−1 (3.441 THz) is obviously weaker. The ...
The realized sensor consists of the following parts: the microfluidic chip where the reaction and absorption measurement take place; the pump for the sample; the pumps for the reagent, wash, and standard solutions; the waste container; and the housing. All parts are described in the following ...

After two years, the mesh bags were removed from the ground and the shale chips were reweighed to determine two-year mass loss. Subsequently, binocular microscopy was used to compare the before and after characteristics of the shale chips through comparison to photographs taken of each chip ...
Hermitically sealed bags are essential for dry foods such as potato chips and various types of cereals to retain their freshness and safety. Autonomous sensors can improve the current shelf life labels by letting both consumers and producers know when the packaged food is fresh and safe. In ...
The leaves were collected and immediately sealed in plastic bags, kept in an ice chest, and then transported to the laboratory for spectral measurements. The measurements were conducted followed those described by Pu et al. (2003) [20]. The light source was a 100 W halogen reflectorized lamp...
