Climate change is leading to a disproportionately large warming in the high northern latitudes, but the magnitude and sign of the future carbon balance of the Arctic are highly uncertain. Using 40 terrestrial biosphere models for the Alaskan Arctic from four recent model intercomparison projects – NACP (North American Carbon Program) site and regional syntheses, TRENDY (Trends in net land atmos...
The in situ application of rice straw enhances CH4 emissions by a large margin. The ex situ application of rice straw in uplands, however, may mitigate total global warming potential (GWP) of CH4 and N2O emissions from paddy-upland coexisting systems. To evaluate the efficiency of this practice, two field trials were conducted in rice-rice-fallow and maize-rape cropping systems, respectively. Y...
Among many environmental problems, soil erosion poses a serious threat to the region known as Chittagong Hill Tracts (CHTs) in Bangladesh, comprising three districts, namely Bandarban, Rangamati, and Khagrachari. The annual rate for this hilly terrain was calculated using Revised Universal Soil Loss Equation (RUSLE) model integrated with Remote Sensing Geographic Information System (GIS). range...
Cancer is the most frequent cause of death in both developing and developed countries, including Korea. The aim of this study was to present survival rates of Korean cancer patients. Survival analysis was carried out with data collected under the Korea Central Cancer Registry Program, which included all cancer patients diagnosed from January 1, 1997 to December 31, 1997. We have analyzed the ef...
The productivity of terrestrial ecosystems is limited by soil fertility, such assoil phosphorus (P). decomposition litter the main process that affects nutrient cycling. To understand characteristics and release under P addition, we conducted a 2-year bag experiment at addition rates (0–12.5 g m−2 yr−1). All decomposed faster during second growing season due to highly concentrated precipitation...
Stathokostas, Liza, Shanthi Jacob-Johnson, Robert J. Petrella, and Donald H. Paterson. Longitudinal changes in aerobic power in older men and women. J Appl Physiol 97: 784–789, 2004. First published March 26, 2004; 10.1152/japplphysiol.00447.2003.—The purpose of this study was to describe the longitudinal (10 yr) decline in aerobic power [maximal O2 uptake (V̇O2 max)] and anaerobic threshold [ve...
[1] Firn-air and ambient air measurements of CHF3 (HFC23) from three excursions to Antarctica between 2001 and 2009 are used to construct a consistent Southern Hemisphere (SH) atmospheric history. The results show atmospheric mixing ratios of HFC-23 continuing to increase through 2008. Mean global emissions derived from this data for 2006–2008 are 13.5 ± 2 Gg/yr (200 ± 30 10 gCO2equivalent/yr, ...
Agroforestry is an agricultural diversification practice that purposefully grows trees together with crops and/or animals. Nitrogen (N) plays a pivotal role in the sustainability and productivity of these systems. In this study, we synthesize our current understanding data availability N dynamics agroforestry systems, providing first comprehensive synthesis on major pathways agroforests. We rev...
The decline of N from N-labelled mature pea residues was followed in unplanted soil over 16.5 yr. Eight years after residue incorporation, 24% of the residue N input was still present in the soil and, after 16.5 yr, 16% of the residue N input remained. A double exponential model successfully described the decay of N from N-labelled pea residues. The total residual N declined with average decay ...
We compared clinical characteristics, management, and clinical outcomes of nonagenarian acute myocardial infarction (AMI) patients (n=270, 92.3 ± 2.3 yr old) with octogenarian AMI patients (n=2,145, 83.5 ± 2.7 yr old) enrolled in Korean AMI Registry (KAMIR). Nonagenarians were less likely to have hypertension, diabetes and less likely to be prescribed with beta-blockers, statins, and glycoprote...
