In vitro collapse of DNA by trivalent cations like spermidine produces torus (donut) shaped DNA structures thought to have a DNA organization similar to certain double stranded DNA bacteriophage and viruses. This has prompted our studies of these structures using freeze-etch low Pt-C metal (9Å) replica TEM. With a variety of DNAs the TEM and biochemical data support a circumferential DNA winding model for hydrated DNA torus organization. Since toruses are almost invariably oriented nearly horizontal to the ice surface one of the most accessible parameters of a torus population is annulus (ring) thickness. We have tabulated this parameter for populations of both nicked, circular (Fig. 1: n=63) and linear (n=40: data not shown) ϕX-174 DNA toruses. In both cases, as can be noted in Fig. 1, there appears to be a compact grouping of toruses possessing smaller dimensions separated from a dispersed population possessing considerably larger dimensions.

Focusing on the interplay between memory and place, this article examines the rationale behind the use of axonometric drawings (axons) in a geographical research study of the Tumen/Tuman River region encompassing the borders shared by China, Russia and North Korea. The concepts of “memory of place” and “place of memory” guide the structure of this project and the flow of this article. “Memory of place” emphasises the lived experience of our physical senses, and helps determine the great potential of visual methodologies in the fields of geographical and landscape research and study. Drawn up using the graphic production techniques of abstracting, foregrounding, highlighting and juxtaposing, axons avail themselves of and inform both realist and idealist states of mind. In contrast, “place of memory” references a particular type of materiality and helps us understand Tumen Shan-shui as a library of memories that reveals a profusion of contested aesthetic, cultural and political meanings. Axons serve to tell narratives revealing desires, actions and undertakings that have shaped and continue to shape the substance of the memory sites in question including infrastructure, architecture and signage. Initially adopted by the author as a medium for recording and communicating due to security restrictions imposed in the border areas in question, the creation of axons generated new insights on methods of documentation in landscape research, and the places and landscapes themselves.

Contemporary trends in popular music incorporate timbres, formal structures, and production techniques borrowed from Electronic Dance Music (EDM). The musical surface demonstrates this clearly to the listener; less obvious are the modifications made to formal prototypes used in rock and popular music. This article explains a new formal section common to collaborative Pop/EDM songs called the Dance Chorus. Following the verse and chorus, a Dance Chorus is an intensified version of the chorus that retains the same harmony and contains the hook of the song, which increases memorability for the audience. As the name implies, the Dance Chorus also incorporates and acknowledges the embodiment performed in this section.

Sound or audio engineering is a branch of the field of engineering, which involves the process of recording sound and reproducing it by various means, as well as storing in order to be reproduced later. Known as sound or audio engineers, these trained professionals work in a variety of sound production fields and expert in recording methods. They can be instrumental to implement the affordable technologies and technical process to distribute the audio data hence, making it accessible for future generations. The current role of these engineers not only to perform or limited to recording session but they create metadata for archiving and preservation for future needs. Currently, product sleeves of ethnographic recordings represent no technical elements of how traditional music recordings are produced. The product details focus only to some extent on historical elements and musical notation. To an audio archivist, declaring what devices are in a recording is not linked with preservation data. Apart from the format, the sleeved design, technical specification is essential to other social scientists such as audio engineer and field recordist of the future. The aim of the present research is to capture optimum dynamic range of the sound and applying a signal processing that would not alter the tonality, timbre and harmonic of the sound. Further applying a suitable information storage for the metadata to be preserve or archived for future accessing and reproduction.
