Minimum requirements for automated peak finding are stated. Methods for measuring the full-energy peak efficiency with calibrated sources are given. Performance tests that ascertain the proper functioning of the Ge spectrometer and evaluate the limitations of the algorithms used for locating and fitting single and multiple peaks are described. Methods for the measurement of and the correction for pulse pileup are suggested. Techniques are recommended for the inspection of spectral-analysis results for large errors resulting from summing of cascade gamma rays in the detector. Suggestions are provided for the establishment of data libraries for radionuclide identification, decay corrections, and the conversion of gamma-ray rates to decay rates. 517 $aANSI Std N42.14-1991 606 $aGermanium diodes$xStandards 615 0$aGermanium diodes$xStandards. 676 $a621.381522 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996279879303316 996 $aANSI Std N42.14-1991$93646494 997 $aUNISA LEADER 06337nam 22006854a 450 001 9910828909703321 005 20200520144314.0 010 $a1-281-24221-7 010 $a9786611242213 010 $a0-387-68923-0 024 7 $a10.1007/978-0-387-68923-4 035 $a(CKB)1000000000410501 035 $a(EBL)372899 035 $a(OCoLC)261324893 035 $a(SSID)ssj0000150942 035 $a(PQKBManifestationID)11136810 035 $a(PQKBTitleCode)TC0000150942 035 $a(PQKBWorkID)10280901 035 $a(PQKB)11332192 035 $a(DE-He213)978-0-387-68923-4 035 $a(MiAaPQ)EBC372899 035 $a(Au-PeEL)EBL372899 035 $a(CaPaEBR)ebr10223612 035 $a(CaONFJC)MIL124221 035 $a(PPN)123744474 035 $a(EXLCZ)991000000000410501 100 $a20071004d2008 uy 0 101 0 $aeng 135 $aur|n|---||||| 181 $ctxt 182 $cc 183 $acr 200 14$aThe Everglades experiments$b[electronic resource] $elessons for ecosystem restoration /$fCurtis J.

It has been designated an International Biosphere Reserve, a World Heritage Site, and a Wetland of International Importance, in recognition of its significance to all the people of the world. However, it is apparent that the Everglades have undergone radical changes in both water flow and water quality over the years. The Everglades Experiments: Lessons for Ecosystem Restoration is a synthesis of the key findings and a summary of the experiments conducted during a fourteen-year period (1989-2003) by the Duke University Wetland Center and its partner institutions. Synthesized by Curtis J. Richardson, the findings are the result of extensive experimental research on the effects of water, nutrients, and fire on the Everglades communities. The research focused on such key questions as: What are the effects of increased nutrient and water inputs on the native plant and animal communities? What is the long-term nutrient storage capacity of the Everglades? and How can water management in the Everglades be improved to maintain the natural communities? This work covers both the structural and functional responses of the Everglades ecosystem via experimental and gradient studies on microbial activity, algal responses, macroinvertebrate populations, macrophyte populations, and productivity in response to alterations to nutrients in soil and water, hydrologic changes, and fire. Importantly, this volume reclassifies the Everglades, provides a comparison of historic and current ecological processes, and presents a new working hydrologic paradigm, which collectively provides essential lessons for the restoration of this vast peatland complex. 410 0$aEcological studies ;$vv. 201. 606 $aEcosystem management$xResearch$zFlorida$zEverglades 606 $aEcosystem management$zFlorida$zEverglades 606 $aRestoration ecology$zFlorida$zEverglades 607 $aEverglades (Fla.)$xEnvironmental conditions$xResearch 607 $aEverglades (Fla.)$xEnvironmental conditions 615 0$aEcosystem management$xResearch 615 0$aEcosystem management 615 0$aRestoration ecology 676 $a639.909759/39 700 $aRichardson$b Curtis J$01624683 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910828909703321 996 $aThe Everglades experiments$93959820 997 $aUNINA
