A California anthropologist, Stuster had helped design U.S. space stations by studying crew productivity in cases of prolonged isolation and confinement: Antarctic research stations, submarines, the Skylab station.
For example, the indirect cost estimate we applied for congenital syphilis ($60,421) was substantially more conservative than that of a 1983 study which estimated the lifetime cost of special educational needs and reduced productivity per case of congenital syphilis at over $200,000 [ 94].
Taking all the results into account, in 26.1% of cases we found increased productivity upon addition of an organic solvent, whereas in 73.9% of cases solvent addition led to a reduction of enzyme productivity.
Fungal biomass followed an upward trend when the genotypes were grown in mixture, but in many cases the productivity of particular combinations could not be predicted from that of the constituents when in monoculture, indicating non-additive effects.
In some cases, the productivity of an undergraduate led directly to progress in the postgraduate's research because the undergraduate was responsible for a small component of the postgraduate's larger project.
In this study, different agro-residues were tested for tannase production under submerged fermentation and it was observed that the high tannase productivity in case of P. emblica and S. cumini leaves corresponded to their high tannin content.
In addition, Mr. Dillon wrote, commissioners' productivity is not monitored, creating "a significant backlog of cases".
The lost productivity per case of untreated chlamydia in females has been estimated at $148 [ 85].
The lost productivity per case of HIV has been estimated at $831,614 [ 6].
Using this 0.5 ratio, the estimated lost productivity per case of untreated STI was as follows: $13 for chlamydia in men; $171 and $34 for gonorrhea in women and men, respectively; and $286 for syphilis in men and women.
