To explain anaerobic nitrite/nitrate production at the expense of ammonium mediated by manganese oxide (Mn(IV)) in sediment, nitrate and manganese respirations were investigated in a strain (Shewanella algae C6G3) presenting these features. In contrast to S. oneidensis MR-1, a biotic transitory nitrite accumulation at the expense of ammonium was observed in S. algae during anaerobic growth with...

The results of a maser survey toward ninety-nine protostars in the Orion molecular cloud complex are presented. The target sources are low-mass protostars identified from infrared observations. Single-dish observations were carried out in the water maser line at 22 GHz and the methanol class I maser lines at 44, 95, and 133 GHz. Most of the detected sources were mapped to determine the source p...

In the current work, a systematic approach is exercised to monitor amended soil reliability for housing development program holistically understand targeted material mixture and building input derived, focusing on three governing parameters: (i) optimum moisture content (OMC), (ii) maximum dry density (MDD), (iii) unconfined compressive strength (UCS). It in essence selection of machine learnin...

We report the detection of spatially-extended mid-infrared emission around the luminous embedded star IRc9 in OMC-1, as seen in 8.8, 11.7, and 18.3 μm images obtained with T-ReCS on Gemini South. The extended emission is asymmetric, and the morphology is reminiscent of warm dust disks around other young stars. The putative disk has a radius of roughly 1. 5 (700 AU), and a likely dust mass of al...

Abstract Powder metallurgy is important in material preparation. Due to the inertness of carbon materials, however, sintering powdered into physically coherent bulks has been a great challenge even at high temperature (2000 °C). Improving activity powders key success consolidation powders. Here ordered mesoporous (OMC) used as starting produce highly homogeneous novel bulks. During 1800 °C, hug...

Entomopathogenic nematodes (EPNs) are obligate parasites of insects. EPNs generally have a broad host range, easily mass reared, and can kill some insects within 48 h. safe for vertebrates, plants, other non-target organisms. However, disadvantages that make them less effective against foliar insect pests such as sensitivity to desiccation, ultraviolet (UV) radiation, high temperatures. The goa...

Laboratory tests for the estimation of compaction parameters, namely maximum dry density (MDD) and optimum moisture content (OMC) are time-consuming costly. Thus, this paper employs artificial neural network technique prediction OMC MDD aggregate base course from relatively easier index properties tests. The grain size distribution, plastic limit, liquid limits used as inputs development ANNs. ...
