Steric Effects of Alkyl Ammonium Salts on the Combustion of Exchanged Smectite Clays
<p>Bomb calorimetry was explored as a new method for determining the cation exchange capacity (CEC) of clays. Smectite clays were modified with several alkyl ammonium salts varying in number of carbons and the spatial orientation of the carbons about the central nitrogen atom. The clays used, …

Use of bioelectrical impedance analysis (BIA) to predict water and energy content of juvenile Rainbow Trout (Oncorhynchus mykiss)
… to effectively assess the well-being of fish. Bomb calorimetry and proximate analysis are currently the most dependable and accurate methods to estimate energy content and body composition. However, bioenergetic studies that employ the traditional methodology necessitate the killing of fish to …

Bioelectrical impedance analysis as a predictor of fish health and energy content in juvenile rainbow trout (Oncorhynchus mykiss)
… done by measuring body content using bomb calorimetry or proximate composition analysis; however, both of these methods necessitate sacrificing the fish in order to obtain accurate data. This has led to research into novel non-lethal methods of analyzing fish tissue so as to determine …

Organic emissions during oven drying of wood
… significant differences between the two samples. Bomb calorimetry was used to measure the heating value of the Douglas fir samples both before and after oven drying. The bomb calorimetry, however, proved to not have the sensitivity to accurately measure the small differences in heating value …

SYNTHESIS AND CHARACTERIZATION OF BIODIESEL FUELS FROM FURFURYL ALCOHOL AND SPENT COFFEE GROUNDS
… <sup>1</sup>H-NMR. FaFurE samples also underwent bomb calorimetry studies. Acid catalysis was unsuccessful at producing either FAMEs or FAEEs from coffee oil. Base catalysis, however, was successful. FAMEs were produced in 73% conversion and FAEEs were produced in 81% conversion under …

Effect of flour protein content on the utilization of shortening and cellulose in biscuits
… content of the biscuits was also determined by bomb calorimetry. No significant differences were detected in biscuit volume, crumb and crust color, or tenderness. The biscuits prepared with lower levels of shortening were moister than the biscuits prepared with higher levels of shortening. Wo …

Custom engineered nanomaterials for energetics and energy applications
… thermo-gravimetry (TG), differential scanning calorimetry (DSC), and bomb calorimetry. TG results indicate the stability of the biocidal content as well as the individual decomposition and oxidation reactions involving the nanomaterials. DSC results are used to quantify the thermal energy …

SEASONAL FLAMMABILITY COMPARISONS OF NATIVE AND EXOTIC PLANTS IN THE POST OAK SAVANNAH, BLACKLAND PRAIRIE, AND PINEYWOODS ECOREGIONS OF TEXAS
… (February) and growing (August) season. Oxygen bomb calorimetry (OBC) and proximate analyses estimated ash-free net heat content (NHC-AF; MJ kg<sup>-1</sup>) and proportions of volatile matter (VM%), fixed carbon (FC%), and ash percent (ash%). Pyrolytic and oxidative thermogravimetric analyses …

Energetics and Mechanism of Boron/Oxidant Combustion Reactions
… systems have been measured by the use of bomb calorimetry, the results being discussed in relation to the probable reactions taking place in each system. Conclusions have been drawn as to the nature of the reactions which provide heat outputs in excess of the theoretical values in the …

Methods Of Analysis For Fermentation Science Products Using Various Analytical Techniques
… Quantitation of Residual Biomass Using Oxygen Bomb Calorimetry (OBC). </p> <p>The first major technique employs liquid chromatography to separate and quantitate major sugars (xylose and glucose) in the saccharification of biomass (switchgrass). Storage conditions can determine the economic …

Local impacts of White-nose Syndrome on the foraging ecology of insectivorous bats
… removed from half the moths in each size class. Bomb calorimetry was used to determine the gross heat (cal/g) of moths in each treatment. To account for potential differences in energetic value among species, specimens of Malacosoma americanum, Halysidota tessellaris, and Iridopsis sp. moths were …

Variation in Egg Components: A Study of Maternal Investment and Resource Partitioning in the Nesting Loggerhead Sea Turtle; Estimating Genic Variation and Mapping Genetic Lineage of a Rare Captive Helodermatid Population: <em>Heloderma Horridum Charlesbogerti</em>
<p>Loggerhead sea turtles have the highest egg yields of any oviparous non-avian reptiles. Blood urea nitrogen levels increased as the season progressed while total blood albumen and total protein levels decreased. Wet egg mass (H = 1.7719 df = 2 p = 0.0375*) and albumen mass (H = 6.0507 df = 2 p = …

Aspects of the community structure and reproductive ecology of the common sea-urchin Parechinus angulosus Leske around the Cape Peninsula, South Africa
… male and female Parechinus by micro-bomb calorimetry were found to be in very close agreement, in fact practically identical. The significant mean size differences between urchins of the 2 study sites could be shown to be very 1 ikely due to the availability of food. This was shown by …
