A field experiment was established in a high elevation red spruce (Picea rubens Sarg.) - balsam fir (Abies balsamea) forest on Mount Ascutney Vermont, USA in 1988 to test the nitrogen (N) saturation hypothesis, and to better understand the mechanisms causing forest decline at the time. The study established replicate control, low and high dose nitrogen addition plots (i.e., 0, 15.7 and 31.4kgNH...
Background: Herpes infections were caused predominantly by sexually transmission diseases. Especially the Herpes simplex viruses 1 and 2 appear in many parts of the body. Dermatologists were difficult to diagnose the infections, they can identify after performing blood and CSF tests. Prevalence of age and sex of herpes infections is important to optimize for herpes control strategies. Therefore...
To establish a short rotation coppice (SRC) system in the temperate region of East Asia, planting was conducted for cuttings from seven species, including Salix eriocarpa, S. gilgiana, gracilistyla, integra, sachalinensis, serissaefolia, and subfragilis, with wide distribution eastern Japan. During cultivation, cheap compost derived swine manure containing high concentrations various nutrients ...
Chronic systemic steroids can suppress the immune system. We aimed to identify impact of frequent steroid bursts on function asthmatic children. Children ages 3-18 years with asthma were divided into study (≥2 bursts/1yr) and control groups (0-1 bursts/1yr). Lymphocyte subsets, mitogen proliferation assays, total IgG, pneumococcal diphtheria/tetanus IgG evaluated. 75 patients enrolled (study gr...
Purpose—The primary objective of this study was to investigate if changes in 18F-FLT kinetic parameters, taken at an early stage after start of therapy, could predict overall survival (OS) and progression-free survival (PFS) in patients with recurrent malignant glioma undergoing treatment with bevacizumab and irinotecan. Experimental Design—High-grade recurrent brain tumors were investigated in...
The Iran Water Resources Management Company constructs many dams to control surface water that provide a new potential for aquaculture activities. Trophic status index and natural potential for fish production were investigated in nine small dam reservoirs from northwest of Iran. Prediction of fish productivity was calculated based on phytoplankton biomass (using chlorophyll a concentration in ...
The phenomenology of neutrino oscillations is extended to the neutron-antineutron oscillations predicted by the grand unified theories. There are six parameters in general describing the one-flavor oscillations: two real Majorana masses (of opposite signs), three Euler’s angles, and a phase multiplier χ. The sum of the Majorana masses, treated as a small parity-violating parameter ǫ, induces th...
The solar contribution to global mean air surface temperature change is analyzed by using an empirical bi-scale climate model characterized by both fast and slow characteristic time responses to solar forcing: t1 1⁄4 0:470:1yr and t2 1⁄4 872yr or t2 1⁄4 1273yr. Since 1980 the solar contribution to climate change is uncertain because of the severe uncertainty of the total solar irradiance satell...
