Erosion and sedimentation that will lead to morphological changes in rivers are found in alluvial rivers. Morphological changes in rivers can cause numerous problems, so studying the shape of alluvial rivers in morphology is very important in morphology science. In this study, morphology changes of the Zohreh River in the Hendijan plain, for a length of about 23 km between latitudes 30´ 49° and...
Methane (CH4 ) fluxes from world rivers are still poorly constrained, with measurements restricted mainly to temperate climates. Additional river flux measurements, including spatio-temporal studies, are important to refine extrapolations. Here we assess the spatio-temporal variability of CH4 fluxes from the Amazon and its main tributaries, the Negro, Solimões, Madeira, Tapajós, Xingu, and Pará...
A new species of Brevitobrilus Tsalolikhin, Brevitobrilus montanus n. sp., found in high mountain lakes and rivers in Granada, Spain, is described. Additional data on Brevitobrilus granatensis (Ocafia &Zullini, 1988) n. comb. are provided. Brevitobrilus raontanus n. sp. is characterized by moderate size (1.3-1.8 mm), amphid aperture width one-quarter the head width, subterminal seta distance fr...
The aim of the present investigation was to get an impression of the geographic influences on the dialectal variation in a country. In previous investigations, the correlations between linguistic distances and geographic distances using dialect data from the Netherlands and Norway were calculated (Gooskens and Heeringa 2004, Nerbonne et al. 1996). The results showed a high correlation in the ca...
This study examined the relationships between different types of urban green and blue space (UGS/UBS) self-reported health (SRH), disparities in benefits associated with them. Using data from a social survey Shandong Province multi-source including remote sensing land use vector polygons parks map service providers, we measured proximity coverage ratio various UGS/UBS types. The Euclidean dista...
Fiji recently experienced a sharp increase in reported typhoid fever cases. To investigate geographic distribution and environmental risk factors associated with Salmonella enterica serovar Typhi infection, we conducted a cross-sectional cluster survey with associated serologic testing for Vi capsular antigen-specific antibodies (a marker for exposure to Salmonella Typhi in Fiji in 2013. Hotspo...
Gregory Bateson was one of the last and most distinguished products of the school of anthropology that Haddon and Rivers created in Cambridge after the Torres Strait Expedition. Beginning his career shortly after Rivers' death, Bateson used the interwar years to create a theoretical approach that continued and deflected that of Haddon and Rivers. His major ethnography from this period, Naven, e...
Today, underwater acoustic communication is developing for its various applications. For signal transmission in underwater using ocean/ sea/lakes/rivers as a medium an appropriate underwater acoustic system is required. The significant characteristic of ocean makes the underwater communication difficult using electromagnetic waves. The characteristics of an acoustic signal make a good candidate...
Genetic structure and diversity of mummichog (Fundulus heteroclitus) populations were investigated using mitochondrial DNA (mtDNA) sequences. Forty-six haplotypes were identified among 208 mummichog from the Elizabeth and York Rivers in Virginia, USA. No evidence of decreased gene or nucleotide diversity for mummichog from polycyclic aromatic hydrocarbon (PAH)-contaminated sites was observed. H...
