The long-term accumulation of Zn in soils provides the microbial community time to adapt to this heavy metal. To assess the effects of long-term exposure to Zn on the metabolic diversity and tolerance to Zn of soil microbial community, the pollution-induced community tolerance (PICT) method, based on the Biolog microtitre plate system, was used. It especially is useful to study gradients of pol...

AIMS To determine whether chelated sources of ferric iron were efficient inhibitors of biofilm formation in Pseudomonas aeruginosa and might be suitable for drug delivery to the lungs of cystic fibrosis (CF) patients via nebulization. METHODS AND RESULTS The response of P. aeruginosa biofilms to elevated iron concentrations in the form of eight structurally varied iron chelators in a microtit...

In the inversion of land surface temperature (LST) from satellite data, obtaining the information on land surface emissivity is most challenging. How to solve both the emissivity and the LST from the underdetermined equations for thermal infrared radiation is a hot research topic related to quantitative thermal infrared remote sensing. The academic research and practical applications based on t...

In this study, planning, design and cost analysis of prefabricated beef cattle barns carried out. Steel mesh was used to strengthen the foundation structure. Galvanized-sheet material as carrier cover material, shaped like a trapezoid cross-section. The barns, which are planned in form tunnel cross-section tie-stalls type, designed for 10, 20 30-cattle be particularly suitable family enterprise...

We developed a blowhole detection method using laser ultrasonic in this study. The blowholes are problem fillet welded lap joints galvanized steel sheets often used automobile manufacturing. Fillet joint composed of 2.3 mm or 1.6 thickness plates were as specimen, and measurement was performed on the sections without with defects whose positions identified advance by RT (radiographical test). I...

With an increase in the service time of high-speed railway tunnels, various defects caused by construction-quality secondary lining begin to appear. How evaluate safety such tunnels and take countermeasures is very important for safe operation tunnels. Based on load-structure method a numerical simulation, this paper studied short-term long-term missing section anti-crack reinforcement mesh pla...

Mechanically stabilized earth walls, MSEW, around Florida were instrumented through their concrete covers to survey corrosion rates of galvanized strip soil reinforcement by polarization measurements. The first broad survey was made 10 years ago as a baseline and a new survey is currently underway to assess long term corrosion rate trends. Initial results of an ongoing survey confirm low rates ...

Heat treatment carried out on steel materials will have an effect the hardness and changes in metal structure iron or steel. The addition of this depends type material used, temperature, cooling medium used such as oil, air, water. In study, cutting knife was increased through a heat process to determine result 2 mm plate. test object is which be heated temperature 850°C, cooled using SAE 35 oi...

rocess and quality control are exP tremely important in achieving optimum production and they have a special place in continuously operating processes. Real-time process monitoring is the comerstone of maintaining an efficient electroplating process. For the steel industry, zinc and nickel electroplating processes used for anticorrosion treatmentl must be monitored to maintain certain standards...
