Effects of Brassica on the human gut microbiota
… moiety. Within this fermentation model, the relative proportions of members of the genus Lactobacillus were found to significantly increase when the microbiota was repeatedly exposed to a broccoli leachate, and 16S rDNA sequencing identified these as L. fermentum. Metabolite analysis detected …

Diet of three mormoopid bats (<i>mormoops blainvillei</i>, <i>pteronotus quadridens</i>, and <i>pteronotus portoricensis</i> ) on Puerto Rico
… Hymenoptera, and Lepidoptera, although the relative proportions of these orders differed among species. Variation in diet was primarily due to species, but season, habitat, and sex also affected the composition of insects in the feces. In addition, species-level identification of prey was …

Estimation of origin-destination flows for dynamic traffic assignment
… flows, deviation from historical data, and relative proportions in historical data. The method can be easily extended to make use of other sources of information such as direct measurements of OD flows from probe vehicles. The framework is extended to allow for nonnegativity and capacity …

Study of the microstructure and mechanical properties of hummingbird wing-bones
… macroscale measurements were taken to compare relative proportions of each of the bones of interest, which included the humerus, radius, and ulna. Upon examining the images produced via micro-computed tomography and scanning electron microscopy, it was found that trabecular bone was present, …

The developmental basis of evolutionary changes in limb proportions
… This diversity is driven by changes in the relative proportions of the three limb segments that are conserved among mammals. Despite the importance of limb proportions to mammalian evolution, the developmental mechanisms that regulate mammalian limb proportions remain largely unknown. In …

The same but better: understanding ceramic variation in the Hebridean Neolithic
… variation is limited to slow drifts in the relative proportions of certain rim forms. Across the Outer Hebrides, decorative elaboration and the presence of large numbers of distinctive vessel forms would appear to mark out certain assemblages seemingly associated with communal gathering and …

Student Learning Heterogeneity in School Mathematics
… respectively). There were differences in relative proportions of students who were distributed across levels and classes. Moreover, grade 9 models were more complex than the reported four achievement levels. To explore intrinsic modeled results further, latent factors were plotted against …

Studies with dithizone : the extraction of thallium (III)
… of intermediate products which depend on the relative proportions of reactants, the pH of the aqueous phase, the order of mixing of reactants, the time of phase equilibrium and the nature of the organic solvent used. The reaction between thallium(III) and dithizone is essentially oxidative in …

Studies of clay minerals and their decomposition products
… in the thermal products of hectorite, their relative proportions varying with temperature. Protoenstatite was stabilised with respect to metastable clinoenstatite upon cooling from 12000 C by the presence of exchanged transition metal cations. Solid state Nuclear Magnetic Resonance …

Avian fauna, palaeoenvironments and palaeoecology in the late quaternary of the Western and Southern Cape, South Africa
… confirmed the close resemblance between the relative proportions of seabirds in archaeological and beached assemblages and earlier assumptions that the composition of seabird samples in archaeological sites could not otherwise have been achieved. It is shown that this simple but effective …

Microbiological Profile of Purulent-Septic Diseases in Maxillofacial Surgery // Микробиологичен профил на гнойно-септичните заболявания в лицево-челюстната хирургия
… descriptive statistics (absolute frequencies and relative proportions). The goals include: determining the overall etiological structure of infections; conducting a comparative analysis of the microbiological profile in odontogenic and non-odontogenic origins; tracking the dynamics of the main …

Therapy of porphyria with oral activated charcoal
… further in the chapters which follow. The relative proportions in which the porphyrins and porphyrinogens exist in tissues ( and indeed in urine, stool and plasma) are largely unknown, though one might expect a considerable proportion to be present as the porphyrin, in view of the rapidity …

Geochemistry of slow-growing corals : reconstructing sea surface temperature, salinity and the North Atlantic Oscillation
… incorporate strontium (Sr) and calcium (Ca) in relative proportions inversely to the sea surface temperature (SST) in which the skeleton is secreted. [Delta]180 of the coral skeleton changes based on both temperature and the [delta]180 of sea water ([delta]Ow), and 6Ow is proportional to sea …

Major Sclerotial Polypeptides Of Psychrophilic Fungi: Identification, Immunological Relatedness, Localization And In Vivo Synthesis
… Typhula incarnata. The number, molecular mass, relative proportions and isoelectric points of the major sclerotial polypeptides varied from species to species. Furthermore, several of the major sclerotial polypeptides were shown to be antigenically related by Ouchterlony double-diffusion and …

The Influence of Environmental Conditions and Co-Occurring Parasites on Blood Physiology in Eastern Hellbenders (<i>Cryptobranchus alleganiensis</i>)
… Here, I measured hematocrit, hemoglobin, relative proportions of polychromatic red blood cells, and white blood cell differentials in a wild population of male Eastern Hellbender salamanders (<i>Cryptobranchus alleganiensis</i>) which remain with their nest for up to ~8 months and have …

Wear and friction studies of alumina: Correlation with electron triboemission
… characterized from SEM micrographs by different relative proportions of plastic flow material and fractured surface in the wear scar. In all but one wear regime, the correlation between the wear volume and cumulative triboemission is modest (linear regression coefficient R2 = 0.71); including the …

Identity and dynamics of the microbial community responsible for carbon monoxide oxidation in marine environments
… of CO-oxidizing marine alpha group organisms. Relative proportions of CO-oxidizing Roseobacter and Paracoccus cells were resolved microscopically by microautoradiography in combination with DAPI and fluorescent-labeled oligonucleotide probes (Substrate Tracking AutoRadiography - Fluorescent In …
