the present experiment was carried out to investigate the nutritive value of banana tree leaves and stems silage by use of in vitro gas production and as well in situ nylon bag techniques. experimental treatments were comprised of: 1- stems and leaves of banana trees (control), 2- stems and leaves of banana trees’ silage without addition of any additive, 3- stems and leaves of banana trees’ sil...

We report new laboratory studies of the radiation-induced destruction of glycine-containing ices for a range of temperatures and compositions that allow extrapolation to martian conditions. In situ infrared spectroscopy was used to study glycine decay rates as a function of temperature (from 15 to 280 K) and initial glycine concentrations in six mixtures whose compositions ranged from dry glyci...

Introduction: After about 400 m of MSL Curiosity rover travel, at Bathurst Inlet, sol 54, two APXS analyses were made. On sol 102 Rocknest_3 at the Rocknest site was also analysed by APXS. Bathurst is part of an in-situ, eroded surface (Fig. 1a). The association of Rocknest_3 (Fig. 1b) with surrounding, similar rocks at the Rocknest site strongly suggests that it has a local origin as well. Bot...

This paper presents an in-situ inspection and experimental investigation on the pore solution pH of concrete cover for the corrosion initiation of rebars under a long-term natural carbonation reaction. A 77-year-old steel mill was inspected, and 35 concrete column cover samples were collected to test the pH of the pore solution and phase compositions layer by layer. The variation in pH and phas...

The LiF–AlF3 system with additions of MgO and MgF2 has been studied by 17O, 25Mg, 27Al 19F in-situ high temperature NMR, ex-situ solid state NMR X-ray powder diffraction for a wide range compositions. description the speciation in melts its evolution different operational parameters such as temperature, time composition were obtained MgF2/MgO-(1-x)LiF-xAlF3 x = 14.5, 25 35.5 mol% systems. signa...

A lack of methods for measuring the protein compositions of individual synapses in situ has so far hindered the exploration and exploitation of synapse molecular diversity. Here, we describe the use of array tomography, a new high-resolution proteomic imaging method, to determine the composition of glutamate and GABA synapses in somatosensory cortex of Line-H-YFP Thy-1 transgenic mice. We find ...

Introduction High precision in situ analysis of trace-element compositions and isotope ratios has revolutionised geochronology and geochemistry over the past decade. Most of the advances are due to the proliferation of laser-ablation microprobe inductively coupled plasma mass spectrometry (ICP-MS) and the rapid development of the multi-collector (MC-) ICP-MS. One of the main benefits of in situ...

Water-flooded oil reservoirs have specific ecological environments due to continual water injection and oil production and water recycling. Using 16S rRNA gene clone library analysis, the microbial communities present in injected waters and produced waters from four typical water-flooded oil reservoirs with different in situ temperatures of 25 °C, 40 °C, 55 °C and 70 °C were examined. The resul...
