The Impact

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

Drawing upon concepts of expressive equipment and body image, the aim of this study is to explore how men diagnosed and treated for penile cancer construct their penis and its surgical disfigurement (penectomy). Using maximum variation sampling with the intention to acquire the broadest range of experiences of stage of disease and treatment, 27 cisgender men (aged 48-83, x=63) who had surgical treatment consented for their data to be archived for analysis. From a dramaturgical perspective, the constructionist thematic analysis explored direct and indirect talk about the penis after surgery. The analysis showed that through graphic and sequential narratives of dismemberment revealed, participants constructed a post-surgery period in which they both wanted and did-not-want to see their penis. Additionally, participants constructed themselves managing difficult emotions through others and seeing themselves being rejected by a potentially desiring (female) Other. The findings extend research on male genitals by showing how the post-surgery penis can function as something hidden but visceral and traumatic when revealed. Importantly, this paper illustrates body image as expressive equipment where body and identity are formed in the image of manhood, which is an intersubjective (sexual) object between self and other.

AbstractThe microscopic surface features of asphalt binders are extensively reported in existing literature, but relatively fewer studies are performed on the morphology of asphaltene microstructures and cross-examination between the surface features and asphaltenes. This paper reports the findings of investigating six types of asphalt binders at the nanoscale, assisted with atomic force microscopy (AFM) and scanning transmission electron microscopy (STEM). The surface features of the asphalt binders were examined by using AFM before and after being repetitively peeled by a tape. Variations in infrared (IR) absorbance at the wavenumber around 1700 cm−1, which corresponds to ketones, were examined by using an infrared s-SNOM instrument (scattering-type scanning near-field optical microscope). Thin films of asphalt binders were examined by using STEM, and separate asphaltene particles were cross-examined by using both STEM and AFM. In addition, connections between the microstructures and binder’s physicochemical properties were evaluated. The use of both microscopy techniques provide comprehensive and complementary information on the microscopic nature of asphalt binders. It was found that the dynamic viscosities of asphalt binders are predominantly determined by the zero shear viscosity of the corresponding maltenes and asphaltene content. Limited samples also suggest that the unique bee structures are likely related to the growth of asphaltene content during asphalt binder aging process, but more asphalt binders from different crude sources are needed to verify this finding.
