To assess the variation in distribution, extent, and NPP of global natural vegetation in response to climate change in the period 1911-2000 and to provide a feasible method for climate change research in regions where historical data is difficult to obtain. In this research, variations in spatiotemporal distributions of global potential natural vegetation (PNV) from 1911 to 2000 were analyzed w...

Understanding the processes that determine above-ground biomass (AGB) in Amazonian forests is important for predicting the sensitivity of these ecosystems to environmental change and for designing and evaluating dynamic global vegetation models (DGVMs). AGB is determined by inputs from woody productivity [woody net primary productivity (NPP)] and the rate at which carbon is lost through tree mo...

Non-paralytic polio (NPP) is commonly thought to be synonymous with "abortive polio," in which the poliovirus neither entered the CNS nor damaged neurons. Described are two epidemic illness -"The Summer Grippe" and Iceland disease -apparently caused by a low virulence but neuropathic type 2 poliovirus, studies showing that neuronal lesions in the brain and spinal cord and muscle weakness were c...

UNLABELLED Spinal cord injury (SCI) causes a high incidence of motor and sensory dysfunctions accompanied with neuropathic pain. No effective treatment is available. Both somatosensory evoked potential (SSEP) and neuropathic pain (NPP) are transmitted via myelinated large diameter fibers of deep sensory pathways. Here we aimed to evaluate whether SSEP can consistently and objectively assess tra...

the present study modeled how future terrestrial net primary productivity (npp) changes spatiotemporally for the eastern mediterranean biomes of turkey using carnegie ames stanford approach (casa) model, moderate resolution imaging spectroradiometer (modis) data, the four regional climate change scenarios (rcp 2.6, rcp 4.5, rcp 6.0 and rcp 8.5), and such ancillary data as percent tree cover, la...

The carbon dynamics of terrestrial ecosystems was globally simulated with a mechanistic model, Sim-CYCLE, at a spatial resolution of 0.5° × 0.5° in longitude and latitude. Gross photosynthetic production (GPP), net primary production (NPP), carbon storage, absorption of photosynthetically active radiation (APAR), and light-use efficiency (LUE) were addressed. Assuming an equilibrium state under...

Forests are dynamic in both structure and species composition, and these dynamics are strongly influenced by climate. However, the net effects of future tree species composition on net primary production (NPP) are not well understood. The objective of this work was to model the potential range shifts of tree species (DISTRIB Model) and predict their impacts on NPP (PnET-II Model) that will be a...

Introduction: There is concern about cancer risk from living near nuclear power plants (NPP). Different studies yield different results and this study seeks to add to the body of knowledge on the topic. Methods: Using an ecological design, pair-wise comparisons were made for cancer death rates (CDR) in three county classifications for U.S. NPPs: counties where a NPP was located, counties that b...

Labile carbon (C), which is principally comprised of non-structural carbohydrates, is an essential intermediary between C assimilation and structural growth in deciduous forests. We developed a new approach that combined meteorological and biometric C cycling data for a mixed deciduous forest in Michigan, USA, to provide novel estimates of whole-ecosystem labile C production and reallocation to...

A 2×2 factorial experiment was conducted to study the effect of dietary calcium and non-phytate phosphorus (nPP) imbalance on calbindin and NaPi-IIb mRNA levels in the small intestine and tibia parameters of broiler chicks. One hundred and forty four 1-d-old Arbor Acres male broiler chicks were divided into four treatments consisted of six replicates with six chicks each. The two dietary calciu...
