Jupiter's interior and deep atmosphere: The initial pole-to-pole passes with the Juno spacecraft

Abstract: On 27 August 2016, the Juno spacecraft acquired science observations of Jupiter, passing less than 5000 kilometers above the equatorial cloud tops Images of Jupiter’s poles show a chaotic scene, unlike Saturn’s poles Microwave sounding reveals weather features at pressures deeper than 100 bars, dominated by an ammonia-rich, narrow low-latitude plume resembling a deeper, wider version of Earth’s Hadley cell Near-infrared mapping reveals the relative humidity within prominent downwelling regions Juno’s measured gravity field differs substantially from the last available estimate and is one order of magnitude more precise This has implications for the distribution of heavy elements in the interior, including the existence and mass of Jupiter’s core The observed magnetic field exhibits smaller spatial variations than expected, indicative of a rich harmonic content

Identifying Global and Culture- Specific Dimensions of Humor in Advertising: A Multinational Analysis

Abstract: Humor is a commonly used communication tool in advertising in the United States, but U.S. marketers know little about its use and effectiveness in foreign markets. Such limited knowledge hinders international managers' ability to determine which aspects of humorous communications are likely to be amenable to global standardization and which should be adapted to local expectations. The authors examine the content of humorous television advertising from four national cultures: Korea, Germany, Thailand, and the United States. Findings indicate that humorous communications from such diverse national cultures share certain universal cognitive structures underlying the message. However, the specific content of humorous advertising is likely to be variable across national cultures along major normative dimensions such as collectivism- individualism.

Release of Inorganic Constituents from Leached Biomass during Thermal Conversion

Abstract: Leaching of inorganic materials has recently been shown to substantially improve the combustion properties of biomass fuels, especially straw but including other herbaceous and woody fuels. Leaching with water removes large fractions of alkali metals (typically >80% of potassium and sodium) and chlorine (>90%). Smaller fractions of sulfur and phosphorus are also removed. Alkali metals are heavily involved in ash fouling and slagging in combustion and thermal gasification systems. Chlorine is a facilitator of alkali volatilization, and contributes to corrosion and air pollution. The presence of these elements has reduced or eliminated the use of certain biomass fuels in many combustion applications, even where such use might provide significant environmental benefits. Leaching could mitigate the undesirable effects of biomass ash in thermal systems. Reported here for the first time are comparative studies of volatile inorganic species evolving from leached and unleached biomass fuels during thermal convers...

Direct evidence for human use of plants 28,000 years ago: starch residues on stone artefacts from the northern Solomon Islands

Abstract: The excavation of Kilu Cave and the discovery of a Pleistocene prehistory for the Solomon Islands have already been reported in ANTIQUITY by Wickler & Spriggs (62: 703–6). Residue analysis of stone artefacts from the site now provides the earliest direct evidence for the prehistoric use of root vegetables, in the form of starch grains and crystalline raphides identifiable to genus. The direct microscopic identification of starch grains opens new avenues for the study of the plant component of human diets in the distant past.
