A simple form of Rayleigh pitot tube formula
Rayleigh pitot tube formula is a very basic and commonly used formula in aerodynamics. It gives the rate of the total pressure behind a normal shock wave and the pressure of freestream at a given Mach number. Although the relation is rigorous in... continue reading
Shallow-transfer problems in Erzya-Moksha conjunctive-preterite2 syncretism
The Mordvin languages, Erzya and Moksha, have as many as eight moods, including the Conj(unctive), and Ind(icative). Both languages have two Ind preterites (Prt1, Prt2) and a non-past. In Erzya, Prt2 and Conj have distinct morphology, whereas, in... continue reading
Calculation of multi-dimensional information acquisition in space potential disintegration target
Some space debris belongs to the upper stage of the rocket, and propellant remains inside the debris, which may explode and generate more space debris. In order to identify potential disintegration targets in space, understand the remaining amount... continue reading
Spacecraft cluster cloud high-frequency optimization computing theory
The satellite-ground collaborative computing requires information transmission between the satellite and the ground, which will cause significant delay, resulting in a time from calculation to execution of more than milliseconds. In the best case,... continue reading
Develop a uniform tool to assess sanitation in urban slums
The quality of sanitation is poor in urban slums across the globe. Sanitation deprivations are greater in urban slums in developing countries, which continually experience unmanageable influxes of slum dwellers.
Governments have limited... continue reading
Utility of kidney dialysis for recovery following marathons or ultra-marathons
Recent observations indicate the presence of Acute Kidney Injury and impaired renal function in a majority of participants in marathons of a standard distance of 42.2km (26.2mi). This impairment, and the resulting electrolyte imbalances, may delay... continue reading
Possible role of ozone depletion in insect depopulation
Insect populations have been found to be precipitately decreasing, with some studies indicating a decline in flying insect biomass of as much as 80% since the 1980s, in some areas. A number of possible causes for this phenomenon have been... continue reading
Pragmatic Autoethnography: Thoughts on why it may be needed
Autoethnography is a reflexive subjective narrative qualitative research method, both a product and a process, whereby the researcher (‘auto’) depicts (‘graphy’) their understanding of their lived experience within an ethnographic (‘ethno’) or... continue reading
Space Debris Fingerprint Definition and Identification
The amount of space debris is increasing, and the threat to normal human space activities is also increasing. The concept of fingerprints of space debris is proposed here. It is necessary to define the fingerprints of space debris, and identify... continue reading
Testing the role of radicals in sleep deprivation`s antidepressant effect.
Recent research on sleep deprivation(SD) has demonstrated in the mouse large free radical increases after two days SD, selectively in the small intestine (and large).1. This timescale closely parallels that of the quick, hard to sustain, human... continue reading
