Abstract. Multisensor data fusion technology is a new frontier technology. According to the demand of greenhouse environment monitoring, the paper puts forward a new kind of data fusion method based on Dempster-Shafer (D-S) evidence theory and agricultural expert system. The experimental results show that the method can improve the veracity of decision of measuring and controlling greenhouse en...

As we saw last week, the worldwide scientific community has reached consensus that global warming is inevitable if humans continue to dump "greenhouse gases" into the atmosphere at anything like present rates. Greenhouse gases include carbon dioxide, methane, nitrous oxide, chlorofluorocarbons (CFCs) and a few others. These gases act like the glass covering a greenhouse, letting sunlight in but...

Farming practices are known to exert strong control over the soils’ function to act as sources or sinks for greenhouse gases (GHG). A recent meta-analysis based on the evaluation of 74 published long-term system comparisons provides a comprehensive data base regarding soil organic matter development (SOM) and C sequestration potential of organic systems (Gattinger et al., 2012). Furthermore, th...

1) there is a natural greenhouse effect that keeps the world warmer than it otherwise would be; 2) greenhouse gases are increasing in the atmosphere because of human activities and they are trapping increasingly more heat; 3) there is a collective picture of a warming world and humans have likely contributed; and 4) continued increase in greenhouse gases is projected to lead to increases in sea...

OBJECTIVE To examine the efficacy of adjunctive right prefrontal high-frequency repetitive transcranial magnetic stimulation (rTMS) treatment in adolescent mania patients as compared to sham stimulation. METHODS Twenty six right handed patients aged 12-17 years diagnosed with bipolar mania were randomized to receive daily sessions of active or sham rTMS (20 Hz, 110% of motor threshold, 20 tra...

This study was conducted to determine status of heavy metals in agricultural soils under different patterns of land use. A total of 38, 40 and 45 soil samples for bare vegetable field, greenhouse vegetable field, and grain crop field were respectively taken from surface layer (0-20 cm) from selected experimental areas away from suburbs of ten counties (or districts or cities) in four provinces ...

Volume 2 • Issue 1 • 1000e104 Adv Dairy Res ISSN: 2329-888X ADR, an open access journal Although water vapour is the largest and essential greenhouse gas inclusive of ozone in the stratosphere, the mitigation of anthropogenic six greenhouse gases such as carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, hydrofluorocarbons and perfluorocarbons have been established as legally binding...

A primitive economic model with classical population theory is constructed in order to examine the greenhouse effect on the sustainability of human population as well as the environmental tax when the sustainability is in danger. The conclusion of this paper is that when the negative effect is small, the tax can guarantee the sustainability, where the effective tax rate interval for the sustain...

Agricultural ecosystems are important contributors to atmospheric greenhouse gasses (GHGs); however, in situ winter emission data in saline-alkali fields are scarce. Gas samples were collected during different periods, from three rice (R1–R3) and three maize (M1–M3) fields with different soil pH levels and salinity conditions. Carbon dioxide (CO2) emissions in the rice and maize fields decrease...

In Reply:—Drs. Parker and Behringer correctly point out that in our review on the potential toxic effects of nitrous oxide we did not cover its contribution to the greenhouse effect; this omission was predicated by considerations of space, direct relevance to patient care, and a lack of relevant data that is less than 20 yr old. Correctly, Drs. Parker and Behringer indicate that nitrous oxide c...
