The lifecycle theory of saving and consumption predicts that changes in an economy’s rate of economic growth will affect its aggregate saving rate by changing the lifetime resources of younger people relative to older people. However, studies that track the saving behavior of cohorts of household heads over time as they age have yielded estimates of age-saving profiles that are too flat for gro...

Body condition may predict individual fitness because those in better condition have more resources to allocate towards improving their fitness. However, the hypothesis that condition indices are meaningful proxies for fitness has been questioned. Here, we ask if intraspecific variation in condition indices predicts annual reproductive success and survival. We monitored a population of Neochmia...
The National Centers for Environmental Prediction–National Center for Atmospheric Research (NCEP–NCAR) reanalysis is used to estimate time trends of, and analyze the relationships among, six indices of cyclone activity or forcing for the winters of 1949–99, over the region 208–708N. The indices are Eady growth rate and temperature variance, both at 500 hPa; surface meridional temperature gradie...
cadmium effects on soil microbial indices and on the interaction of arbuscular mycorrhiza fungi (amf) and as well on plant growth promoting rhizobacteria (pgpr) were investigated. the experiments were performed in the framework of a factorial design with levels of cadmium (0, 10, 30 and 100 mg kg-1 soil), and microbial inoculations (control, pgpr and amf) employing russian kanapweed as the expe...
Background and purpose: Increase in elderly population of a country requires new policies and plans. Therefore, it is necessary to study the state of aging in the country and different provinces. This research aimed to study the status of population aging based on the recent census data and identifying effective factors in Iran. Materials and methods: Indicators of population aging, including ...
