BACKGROUND Guillain-Barré Syndrome (GBS) is a severe paralytic neuropathy associated with virus infections such as Zika virus and Chikungunya virus. There were also case reports of dengue fever preceding GBS. With the aim to understand the mechanisms of GBS and dengue outbreaks, this ecological study investigates the relationships between GBS, dengue, meteorological factors in Hong Kong and glo...
Huang H., Han Y., Song J., Zhang Z., Xiao H. (2016): Impacts of climate change on water requirements of winter wheat over 59 years in the Huang-Huai-Hai Plain. Soil & Water Res., 11: 11–19. Daily data from 40 meteorological stations in the Huang-Huai-Hai Plain from 1955 to 2013 were analyzed using the Mann-Kendall test and partial correlation to determine the temporal trends of meteorological f...
Fasciola hepatica is an important trematode parasite of economic importance that infests sheep and cattle worldwide. We conducted a detailed investigation into the spatial distribution of F. hepatica infestation in farmed sheep in Qinghai (Wutumeiren) province, Mainland China. Mathematical modelling was used to assess the inter-relationships between meteorological and geographical factors and t...
Prediction method for large diatom appearance in winter with meteorological data and MODIS derived turbidity and chlorophyll-a in Ariake Bay Area in Japan is proposed. Mechanism for large diatom appearance in winter is discussed with the influencing factors, meteorological condition and in-situ data of turbidity, chlorophyll-a data with the measuring instruments equipped at the Saga University ...
The factors determining the spatial and temporal distribution of West Nile virus (family Flaviviridae, genus Flavivirus, WNV) activity are not well understood. Here, we explore the effects of hydrological and meteorological conditions on WNV infection among Culex genus mosquitoes collected during 2001-2009 in Suffolk County, Long Island, NY. We show that WNV infection rates in assayed pools of ...
according to webster and wind (1972) and anderson et al (1987), “organizational buying is a complex process and involves many people from different functional areas, multiple goals and potentially conflicting decision criteria. moreover, the customers of today are also more knowledgeable and selective when making their purchasing decisions. since a key to organizational survival is the retentio...
Extended Abstract Introduction and Objective: Meteorological indexes are among the factors affecting the yield of various agricultural and livestock products. Given the leading climate change, examining the impact of meteorological limit indices on livestock production can now be an important challenge for producers. Therefore, the purpose of this meteorological analysis is on the trend of Ira...
To clarify the mechanism of radon transport from soil to surface, long term continuous measurements of radon exhalation were conducted at one site in combination with measurements of radon concentration in soil gas, soil temperature, pressure difference, soil moisture and meteorological parameters. Based on the results of measurements over a two year period, the influence of meteorological and ...
With the consideration of the existing Ka-band satellite channel model in data processing method deficiency, the Ka-band satellite channel propagation characteristic is analyzed and the influence of meteorological factors on the satellite channel is discussed. The channel of meteorological factor principal component is obtained by using the principal component analysis and fuzzy clustering anal...
