abstract the aim of this study is of the effect of structural changes in higher education on changes of output in sistan and baluchestan province using structural decomposition analysis (sda). the input-output tables of this region for the period 2006-2011 have been employed as the database of the model. the structural changes were decomposed into two factors: changes in share of specific secto...

To better understand the formation processes of biogenic secondary organic aerosols (SOAs) over remote oceanic regions, aerosol samples were collected from 2010 to 2012 at Chichijima Island in western North Pacific (WNP). The analyzed by gas chromatography-mass spectrometry for SOA tracers, which are produced photochemical oxidation volatile compounds (BVOCs), including isoprene, monoterpenes, ...

Spring-based artificial reverberation was one of the earliest attempts at compact replication of room-like reverberation for studio use. The popularity and unique sound of this effect have given it a status and desirability apart from its original use. Standard methods for modeling analog audio effects are not well suited to modeling spring reverberation, due to the complex and dispersive natur...

Background We intend to study the inhibitory effect of sulfur compound in Ramsar hot spring mineral on tumor-genesis ability of high natural background radiation. Objective The radioprotective effect of sulfur compounds was previously shown on radiation-induced chromosomal aberration, micronuclei in mouse bone marrow cells and human peripheral lymphocyte. Ramsar is known for having the highes...

Warming in northern high latitudes has changed the energy balance between terrestrial ecosystems and the atmosphere. This study evaluated changes in regional surface energy exchange in Alaska from 2000 to 2011 when substantial declines in spring snow cover due to spring warming and large-scale fire events were observed. Energy fluxes from a network of 20 eddy covariance sites were upscaled usin...

Based on ambient air quality data of the four key cities (Nanning, Liuzhou, Guilin, and Beihai) in Guangxi, China, along with an analysis main emission sources, topographic features, weather conditions, backward trajectories, variation pollutants pollution episodes were studied. Results showed that was most serious Liuzhou followed by Nanning Beihai. PM2.5 dominant pollutant each city, O3, PM10...

To improve our mechanistic understanding and predictive capacities with respect to climate change effects on the spring phytoplankton bloom in temperate marine systems, we used a process-driven dynamical model to disentangle the impact of potentially relevant factors which are often correlated in the field. The model was based on comprehensive indoor mesocosm experiments run at four temperature...
