development of mini-gypsum blocks for soil moisture measurement and their calibration to compensate for temperature
to measure soil water content (or soil matric suction) in thin layers of about 30mm, conventional gypsum blocks are not suitable. to carry out the task, mini-gypsum blocks were constructed using plaster of paris in an innovative fashion. a power relationship was found between the soil water content and the mini-gypsum blocks’ readings in kω. the calibration results showed that readings of m...
متن کاملOxygen sensor via the quenching of room-temperature phosphorescence of perdeuterated phenanthrene adsorbed on Whatman 1PS filter paper.
Perdeuterated phenanthrene (d-phen) exhibits strong room-temperature phosphorescence (RTP) when adsorbed on Whatman 1PS filter paper. An oxygen sensor was developed that depends on oxygen quenching of RTP intensity of adsorbed d-phen. The system designed employed a continuous flow of nitrogen or nitrogen-air onto the adsorbed phosphor. The sensor is simple to prepare and needs no elaborate fabr...

The Changing Distribution of Job Satisfaction The distribution of job satisfaction widened across cohorts of young men in the U.S. between 1978 and 1988, and between 1978 and 1996, in ways correlated with changing wage inequality. Satisfaction among workers in upper earnings quantiles rose relative to that of workers in lower quantiles. An identical phenomenon is observed among men in West Germ...
متن کاملCalibration and validation of a soil water simulation model (WaSim) for field grown Amaranthus cruentus
A water simulation model (WaSim) to simulate the growth and development of Amaranthus cruentus as well as the components of water balance for a typical sandy-clay-loam soil of Akure has been described. Dry season experiments were carried between January and March of 2005 and 2006. Amaranthus seeds were established on the field and three irrigation water managements were imposed on the crop to d...
متن کاملwhatman paper (fta cards) for storing and transferring leishmania dna for pcr examination
background: diagnosis of cutaneous leishmaniasis (cl) is often made based on clinical manifestation. correct diagnosis and identification of the parasite are crucial for choosing the effective treatment and for epidemiological studies. on the other hand, determination of leishmania species is necessary for designing appropriate control programs. diagnosis by pcr is becoming a 'gold standard'...
