At a river crossing, people usually prefer taking a bridge to swimming. However, if the bridge seems not to be strong enough, what would they do? The authors conducted a retrospective study to demonstrate the usefulness of intraoperative bowel decompression and irrigation in patients with left colonic obstruction or left colon perforation [1]. They used a new intraoperative colonic irrigator (N...

intra-city natural structures have always had a key role in creating sustainable urban greenspaces. adapting to natural features and relating the intra-city greenspaces to such natural structures as river-valleys, hillsides, lakes and forests, guarantee the endurance, sustainability and longevity of the natural quality of city. this paper looks at intra-city natural structures which have underg...

Protodioscin is used as a marker of saponin content that could cause hepatotoxicity in ruminants. In Brachiaria spp. from two regions of the Colombian Eastern Plains (east mountain range of the Andean-"piedemonte" and Ariari River Valley) were determined this metabolite at 14 and 28 days post-cutting under different climatic conditions. No protodioscin was detected in B. dictyoneura or B. humid...

Anthropogenic disturbances in nature can be defined by energy and emergy terms. I studied four saline meadows with different protection status to see if they differ in species richness and plant biomass of halophytes and in the level of anthropogenic disturbance. The four studied meadows were located in the Kujawy region, the central part of Poland. The first study area was the reserve of halop...

As extreme surface processes, long-term river damming and outburst events can impact sediment supply transportation in valleys therefore significantly change the landscape. Lacustrine sediments were identified wide Xigaze Valley, middle reaches of Yarlung Tsangpo River Tibet, an area which has been considered to have a paleodammed lake. However, evolutionary process mechanisms associated with t...

The cultivated/domesticated peach (Prunus persica var. persica; Rosaceae, subgenus Amygdalus; synonym: Amygdalus persica) originated in China, but its wild ancestor, as well as where, when, and under what circumstances the peach was domesticated, is poorly known. Five populations of archaeological peach stones recovered from Zhejiang Province, China, document peach use and evolution beginning c...

This study investigates the effects of reductions in nitrogen oxide (NOx) emissions from major point sources on daily maximum 8-h ozone concentrations in the eastern United States. The Community Multiscale Air Quality (CMAQ) model was utilized in photochemical simulations on a matrix of modeling scenarios permitting an examination of the separate effects of emission changes and meteorological i...
