Terrestrial sulfidic springs support diverse microbial communities by serving as stable conduits for geochemically diverse and nutrient-rich subsurface waters. Microorganisms that colonize terrestrial springs likely originate from groundwater, but may also be sourced from the surface. As such, the biogeographic distribution of microbial communities inhabiting sulfidic springs should be controll...

Structural health monitoring is attracting attention as an effective means to understand the functional continuity of a building after earthquake. Previous studies have reported that continuous use buildings was restricted damage their foundation structures despite minor themselves. We propose identify soil springs using subspace method one indirect methods; then, this approach verified via num...

This paper describes four recent applications of analytical pyrolysis in environmental science and engineering. In all applications, samples were analyzed in order to provide information about the origin of organic matter or changes to an organic matrix. In the first application, pyrolysis-gas chromatography/mass spectrometry (GC/MS) and pyrolysis-GC/flame ionization detection (FID) were used t...

Nematodes are the most abundant type of animal on earth, and live in hot springs, polar ice, soil, fresh and salt water, and as parasites of plants, vertebrates, insects, and other nematodes. This extraordinary ability to adapt, which hints at an underlying genetic plasticity, has long fascinated biologists. The fully sequenced genomes of Caenorhabditis elegans and Caenorhabditis briggsae, and ...

A three-dimensional finite element analysis was carried out for the influence of soil-structure interaction (SSI) on seismic response an isolated continuous bridge with a friction pendulum system (FPS). SSI modelled using soil resistance vs deflection nonlinear springs (following p-y curves). The dynamic behaviour and bridges different coefficients FPS were investigated six measured ground moti...

In general, water cannot be economically pumped through raceways; it must flow through them by gravity. The need for large volumes of good quality water is the principal reason raceways have been limited to sites with large springs. Most raceway culture in the U.S. is with coldwater species such as trout and is based around locations with high volume, cold springs, or creeks. A few raceway syst...

Land use and occupation by agriculture urbanization generate several impacts on the natural environment water quality in a watershed is main parameter capable of reflecting consequences anthropogenic activities that occur this location. Protecting resources their tributaries utmost importance for preservation nature health population relation to direct indirect consumption water. In sense, obje...

background: geothermal waters could be suitable niches for thermophilic free living amoebae includ­ing naegleria and hartmannella . ardebil province, northwest iran is popular for having many hot springs for recreational and health purposes activity. the present research is the first molecular based investigation regarding the presence of naegleria and hartmannella in the hot springs of ardebil...

We present the design and development of a plant-inspired robot, named Plantoid, with sensorized robotic roots. Natural roots have a multi-sensing capability and show a soft bending behaviour to follow or escape from various environmental parameters (i.e., tropisms). Analogously, we implement soft bending capabilities in our robotic roots by designing and integrating soft spring-based actuation...

In the conventional static analysis of building frames, base is idealised on rigid supports and subdivided into three parts namely, superstructure, foundation ground soil, before design. real life situations, soil underneath undergoes deformations which may alter performance structure. this paper, it studied effect type response a frame system with both fixed flexible base. The Winkler model so...
