Remaining phosphorus estimated by pedotransfer function

Phosphorus metabolites in the human placenta estimated in vivo by magnetic resonance spectroscopy.

Normal human placental metabolism has been studied in vivo by image localised 31P magnetic resonance spectroscopy in 13 women with anterior placentas; five, however, were too fat for useful spectral signals to be obtained. Magnetic resonance spectra of good quality which were considered to have arisen from the placenta were obtained from seven women with uncomplicated pregnancies (median gestat...

RNA function and phosphorus use by photosynthetic organisms

Phosphorus (P) in RNA accounts for half or more of the total non-storage P in oxygenic photolithotrophs grown in either P-replete or P-limiting growth conditions. Since many natural environments are P-limited for photosynthetic primary productivity, and peak phosphorus fertilizer production is inevitable, the paper analyses what economies in P allocation to RNA could, in principle, increase P-u...

The value of remaining lifetime is close to estimated values of life.

Workers under 50 on average will spend 10-20% of their future hours working. So, assuming they value leisure time at the wage rate, the value of their lives is 5-10 times their future lifetime earnings. This value is close to values of life estimated by compensating wage differentials or willingness to pay.

Estimating Hydraulic Conductivity Using Pedotransfer Functions

Phosphorus release from ash and remaining tissues of two wetland species after a prescribed fire.

Dead plant tissues and ash from a prescribed fire play an important role in nutrient balance and cycling in the Florida Everglades ecosystem. The objective of this study was to assess the dynamic changes in total phosphorus release (TPr) from ash or tissues of either cattail (Typha domingensis Pers.) or sawgrass (Cladium jamaicense Crantz) to water. Natural-dead (senesced-dead) and burning-dead...
