This chapter extends the book’s insights about nature, technology, and nation to the larger history of the modern period. While the modern nation loses its grip as a locus of identity and analysis, attempts to understand the operation, disruption, and collapse of continental and global infrastructures continue to mix the natural and the machinic in ways that define them both. Those vulnerabilities emphasize large-scale catastrophe; historiographically, they mask the crucial role of small-scale failures in the experience and culture of late modernity, including its definition of nature. Historical actors turned the uneven geographical distribution of small-scale failures into a marker of distinctive local natures and an element of regional and national identity. Attending to those failures helps not only situate cold-war technologies in the larger modern history of natural and machinic orders; it helps provincialize the superpowers by casting problematic “other” natures as central and primary.

The geographical distribution and ages of larvae of the blue grenadier, Macruronus novaezelandiae, based on ichthyoplankton surveys in southern Australian waters in 1984 and 1985, indicate that the species spawns primarily off the west coast of Tasmania in winter, and may spawn on a lunar cycle. Winter spawning off Tasmania is also suggested by adult gonad morphology: gonado-somatic indices peaked in winter, and mature and spent individuals were collected off the west coast of Tasmania. Small numbers of larval blue grenadier were also collected off north-eastern Tasmania, suggesting the occurrence of small-scale and sporadic spawning in that area. The date of first spawning differed by a month between 1984 and 1985, and was apparently related to broad-scale interannual differences in the oceanography of southern Australian waters. Use of oceanographic features to retrocast spawning dates for blue grenadier suggests that shifts in the date of first spawning of approximately one month are common in this species.

Xylebrous morstatti Hag. is a shot-hole borer which is well known as a pest of coffee. It has also been recorded from avocado pear (Persea americana) in Fiji, and is here reported attacking the same tree in the Seychelles, where it appears to be too scarce so far to do any serious damage.The infestations and nature of the damage on avocado pear are described and illustrated, and the recorded geographical distribution of the insect is summarised.A method of insecticidal control is described which, on the small scale on which it was carried out, appears to have been successful.

In the present study, distribution and abundance of Munronia pinnata (Wall.) Theob. in Sri Lanka were explored in 6 provinces, 7 districts, 68 Divisional Secretariat Divisions (DSD) and 395 Grama Niladari (GN) areas. Fifty three GN areas were identified as M. pinnata abundant areas. In 217 GN areas, the plant is found in small scale and in 65 GN areas it was rarely found. M. pinnata was not found in 8 DSDs. Ten new localities were found and three of them were in the wet zone. The highest diversity was found in Monaragala and Matale districts. Populations well adopted for a range of climatic conditions were observed in Madulla, Nilgala, Warakapola, Ritigala and Haldumulla. Monaragala, Wellawaya, Mathurata, Meemure and Kithulpe were identified as unique populations for conservation. Monaragala, Badulla and Matale appear to be the most suitable districts for commercial cultivation of M. pinnata. This is the first record of an extensive systematic survey on the distribution of M. pinnata in Sri Lanka.Key words: Munronia pinnata; Systematic survey; Meliaceae; Conservation; Cultivation; Medicinal plants.DOI: 10.3329/bjpt.v18i1.7837Bangladesh J.

Intergroup Conflict ◽

Abstract De Dreu and Gross predict that attackers will have more difficulty winning conflicts than defenders. As their analysis is presumed to capture the dynamics of decentralized conflict, we consider how their framework compares with ethnographic evidence from small-scale societies, as well as chimpanzee patterns of intergroup conflict. In these contexts, attackers have significantly more success in conflict than predicted by De Dreu and Gross's model. We discuss the possible reasons for this disparity.

AbstractWe applied advanced image enhancement techniques to explore in detail the characteristics of the small-scale structures and/or the low contrast structures in several Coronal Mass Ejections (CMEs) observed by SOHO. We highlight here the results from our studies of the morphology and dynamical evolution of CME structures in the solar corona using two instruments on board SOHO: LASCO and EIT.

A new family of scanning probe microscopes has emerged that is opening new horizons for investigating the fine structure of matter. The earliest and best known of these instruments is the scanning tunneling microscope (STM). First published in 1982, the STM earned the 1986 Nobel Prize in Physics for two of its inventors, G. Binnig and H. Rohrer. They shared the prize with E. Ruska for his work that had led to the development of the transmission electron microscope half a century earlier. It seems appropriate that the award embodied this particular blend of the old and the new because it demonstrated to the world a long overdue respect for the enormous contributions electron microscopy has made to the understanding of matter, and at the same time it signalled the dawn of a new age in microscopy. What we are seeing is a revolution in microscopy and a redefinition of the concept of a microscope.Several kinds of scanning probe microscopes now exist, and the number is increasing. What they share in common is a small probe that is scanned over the surface of a specimen and measures a physical property on a very small scale, at or near the surface. Scanning probes can measure temperature, magnetic fields, tunneling currents, voltage, force, and ion currents, among others.
