Rhizobium sp. H41 isolated from weathered tuff can weather tuff and release Fe, Si, and Al from the rock under nutrient-poor conditions. Here, we report the draft genome sequence of strain H41, which may facilitate a better understanding of the molecular mechanism involved in rock weathering by the bacterium.

the ability of trees to trap dusts convinces their use for preventing the transport of dust over longer distances. this ability is increasingly important in threatened areas with dust invasion. the purpose of this study was to compare the size and distribution of particles deposited on the leaves surface of fraxinus rotundifolia, platanus orientalis, and robinia pseudoacacia trees, in paveh, we...

In spite of increasing demands for service, many municipal street departments in Iowa have faced budget shortfalls due to revenue limitations. These budget shortfalls do not allow them to maintain an aging street system adequately without careful planning. Thin maintenance surface (TMS) techniques have been developed to extend pavement life by mitigating existing distresses. TMS techniques, suc...

background and objectives: in the last few decades, losses of our cultural heritage due to biodeteriorationare beinghighly recognized. from museum objects to rock monuments, the microbial biodeterioration agents are found to be the most destructive. possibilities for proper preservative measure(s) are always more when it is only a monument, statue, museum article, or pre-historic art in any sma...

The aim of the present study was to perform morphological and chemical characterizations microplastics (MPs) found in seawater samples from coast city Fortaleza (CE) using Fourier-transform infrared (FTIR) spectroscopy, Raman spectroscopy differential scanning calorimetry (DSC). Sampling performed a neuston sampler. MPs were separated based on difference density. with varied morphologies found....

Demonstrated that analog of diffractive and refractive 3D optics in free space can be developed to manipulate surface waves such as surface plasmon polaritons (SPPs). It has been shown that an air-gap control of a floating dielectric block can generate the dynamic phase and amplitude modulation of the SPP transmission coefficient. Unlike conventional bulk optics, the nano-scale surface optics f...

Abstract 7 Long sampling tubes are often required for particle measurements in street 8 canyons. This may lead to significant losses of the number of ultrafine (those below 9 100 nm) particles within the sampling tubes. Inappropriate treatment of these losses 10 may significantly change the measured particle number distributions (PND), because 11 most of the ambient particles, by number, exist ...
