introduction long-term climate records are valuable for environmental planning, and tree rings allow records to extend to the time before the establishment of weather stations. for a better understanding of the past climate fluctuation and to mitigate the effect of climate fluctuation, dendroclimatic reconstructions have been applied in many parts of the world. inter annual variations of climat...

T elimination of health disparities in the United States is a national priority and overriding goal for Healthy People 2010 (HP 2010). Surveillance of health indicators among minority populations is essential to eliminating disparities. Surveillance is critical for program planning, policy making, evaluating population-based strategies, and tracking progress toward national and state objectives.

background: cigarette smoking is one of the most important health‑related risk factors in terms of morbidity and mortality. in this study, we introduced a new method for deriving the transitional probabilities of smoking stages from a cross‑sectional study and simulated a long‑term smoking behavior for adolescents. methods: in this study in 2010, a total of 4853 high school students were random...

During the academic year, Army ROTC cadets are required to participate in mandatory physical training; however, during summer months training is not required. The purpose of this study was to determine if there is a change in cadet VO2max after the summer when training is not mandatory. Participants completed a graded exercise treadmill test to determine their VO2max in late spring of 2010 and ...

Summer repeated hydrographic surveys and 4 years of mooring observations are used to characterize for the first time the interannual variability of the bottom water in the Mertz Glacier Polynya (MGP) on the East Antarctic shelf (142 E–146 E). Until 2010, large interannual variability was observed in the summer bottom salinity with year-to-year changes reaching 0.12 in Commonwealth Bay, the regi...

introduction: air temperature as an important climatic factor can influence variability and distribution of other climatic parameters. therefore, tracking the changes in air temperature is a popular procedure in climate change studies.. according to the national academy in the last decade, global temperature has raised 0.4 to 0.8⁰c. instrumental records show that, with the exception of 1998, th...
