No full textThis dataset comprises information extracted from case studies of animal and plant conservation translocation published in the first six volumes (2008-2018) of the IUCN/SSC's 'Global Reintroduction Perspectives' series. It includes: project metadata; summary project methods; self-reported information relating to any mortality, ill-health or reproductive compromise; and any health management practices mentioned in the case studies.
The data are summarised in an accompanying data article (Beckmann & Soorae. 2022. Conservation translocations from the ‘Global Reintroduction Perspectives’ series: Disease and other biological problems. http://doi.org/10.1002/2688-8319.12163)

The reorientation of t-butyl groups in butylated hydroxytoluene: A deuterium nuclear magnetic resonance spectral and relaxation time study
No full textDeuterium nuclear magnetic resonance (NMR) spectra and spin-lattice relaxation times were determined in order to study the dynamics of t-butyl groups in butylated hydroxytoluene. The results are consistent with a model first proposed by Beckmann et al. [J. Magn. Reson. 36, 199 (1979)], where there is an inequivalence between the methyl groups within each t-butyl group. While two methyl groups reorient rapidly relative to the whole t-butyl rotation, the remaining methyl group is more restricted in its motion, reorienting at a rate comparable to that of the t-butyl group itself. The spin-lattice relaxation data show two T1 minima, the high temperature minimum (40-degrees-C) corresponding to the combined t-butyl and "slow" methyl rotations, and the low temperature minimum corresponding to "fast" methyl group rotation. Using an explicitly defined T1 fitting function, the T1 data yield activation energies of 2.2 and 6.0 kcal/mol for the fast methyl and t-butyl rotations, respectively, both in agreement with Beckmann's values obtained from proton T1 experiments. It was also possible to simulate the low temperature deuterium NMR spectra from T = - 160-degrees-C to T = - 80-degrees-C using the aforementioned dynamical inequivalence between the t-butyl methyl groups. While the fast methyl group rotation was in the motional narrowing region for T > - 160-degrees-C, it was possible, from the simulations, to determine the t-butyl exchange rates to within 10%. The jump rates are remarkably close to the values predicted from the T1 results. Above - 80-degrees-C, the spectra could not be simulated, implying that a third motion must be present to further alter the high temperature line shapes. The effective axial asymmetry of the T > - 20-degrees spectra indicates that the additional motion involves a two site exchange.PT: J; CR: ABRAGAM A, 1961, PRINCIPLES NUCLEAR M, P451 ALBERT S, 1972, J CHEM PHYS, V56, P1332 ALBERT S, 1976, J CHEM PHYS, V6, P3277 ALBERT S, 1976, J CHEM PHYS, V64, P3277 ARONSON M, 1981, CHEM PHYS, V63, P349 BECKMANN P, 1978, J MAGN RESON, V32, P391 BECKMANN P, 1979, J MAGN RESON, V36, P199 BECKMANN P, 1981, CHEM PHYS, V63, P359 BECKMANN PA, 1984, J MAGN RESON, V59, P63 BEVINGTON PR, 1969, DATA REDUCTION ERROR, CH11 BLOEMBERGEN N, 1948, PHYS REV, V73, P679 BLOOM M, 1980, CAN J PHYS, V58, P1510 DAVIS JH, 1976, CHEM PHYS LETT, V42, P390 DAVIS JH, 1983, BIOCHIM BIOPHYS ACTA, V737, P117 DRUYAN ME, 1976, J AM CHEM SOC, V98, P4801 ELSAFFAR ZM, 1972, J CHEM PHYS, V56, P1477 FABER DH, 1974, ACTA CRYSTALLOGR B, V30, P449 FROST JC, 1980, PHILOS T ROY SOC B, V290, P567 FROST JC, 1982, J CHEM SOC FARAD T 2, V78, P2139 GALL CM, 1981, J AM CHEM SOC, V103, P5039 GOLDBERG I, 1975, ACTA CRYSTALLOGR B, V31, P2592 GRIFFIN RG, 1981, METHOD ENZYMOL, V72, P108 HASEBE T, 1985, J CHEM SOC FARAD T 2, V81, P735 HASEBE T, 1985, J CHEM SOC FARAD T 2, V81, P749 HURT CJ, 1975, ACTA CRYSTALLGR, V91, P273 LEADBETTER AJ, 1985, J CHEM SOC FARAD T 2, V81, P1067 MAZEBAUDET M, 1973, ACTA CRYSTALLOGR B, V29, P602 MCKENZIE TC, 1975, ACTA CRYSTALLOGR B, V31, P1778 MOOIBROEK S, 1985, CAN J CHEM, V63, P2926 MOOIBROEK S, 1988, CAN J CHEM, V66, P734 OREILLY DE, 1973, J CHEM PHYS, V59, P3576 OWEN NL, 1974, INTERNAL ROTATIONS M, P157 POWLES JG, 1953, J CHEM PHYS, V21, P1695 POWLES JG, 1953, J CHEM PHYS, V21, P1704 RIPMEESTER JA, 1985, J CHEM PHYS, V82, P1053 SPIESS HW, 1981, J MAGN RESON, V42, P381 STEJSKAL EO, 1958, J CHEM PHYS, V28, P388 STEJSKAL EO, 1959, J CHEM PHYS, V31, P55 TORCHIA DA, 1982, J MAGN RESON, V49, P107 VEGA AJ, 1987, J CHEM PHYS, V86, P1803 WITTEBORT RJ, 1987, J CHEM PHYS, V86, P5411; NR: 41; TC: 13; J9: J CHEM PHYS; PG: 8; GA: FA778Source type: Electronic(1

An (s, S) inventory system with Poisson demands and exponential lead time
No full textThis paper considers a stochastic inventory system with Poisson demand and exponentialy distributed delivery time. Unsatisfied demand is lost. Optimality of an s, S policy and D = S–s ≥ s are assumed. The steady state probabilities of the system are calculated, average costs are obtained and the minimized. Two limiting cases may be solved in closed form: rate of demand much larger or much smaller than rate of delivery. In the last case the Wilson lot size formula is regained. Stochastic inventory systems have been studied extensively in the literature (see, for example, Arrow, Karlin and Scarf 1958. Hadley and Within 1963, Veinott and Wagner 1966, Beckmann 1961, Kaplan 1970, Simon 1971, Sivazlian 1974
