Researchers concerned both with diesel exhaust health effects and with mechanisms of particulate matter (PM) formation have an interest in gaining understanding of PM size distributions from heavy-duty on-road diesel engines. Prior research has been done on particulate size measurement but the results fall short in understanding PM size distributions because of the response time or size range of the instruments used. This study reports the transient size distributions of PM from a 1992 Detroit Diesel Series 60 on an engine dynamometer from a full flow dilution tunnel for a FTP Transient Cycle using a Cambustion ® Differential Mobility spectrometer (DMS 500). The size bins selected for this study for the nucleation and accumulation modes were 20nm and 60nm bins, respectively. The accumulation mode during the accelerations and the nucleation mode during the decelerations were clearly observed from the distributions with respect to time. Distributions were also observed during the test cycle showing the transition between the two modes. From the results obtained from the analysis, no strong correlation between the 60nm particles and engine speed was observed even though higher counts of accumulation particles were observed at the same time that the vehicle activity occurred. Similarly, there was no correlation between the accumulation mode particles and power. When the distributions of nucleation and accumulation mode particles were plotted against each other, there was no correlation or anti-correlation. The average size distributions were also analyzed during the four periods of the FTP Transient cycle and the highest counts were observed during the Los Angeles Freeway (LAF) period. Also, higher counts at the second New York Non Freeway (NYNF) were observed during the cycle.

In further exploration of structural fire as an urban parasite, the influence of areal population density and housing overcrowding on incidence and average size of structural fires is analyzed. Because the more people per square mile and per room the greater the incidence and size of the structural fires, the destruction of housing by fire and fire-related building abandonment creates fertile ground for even greater fire damage due to the crowding of the refugees into the remaining housing stock. The vicious circle of housing overcrowding and fire holds serious implications with respect to other density dependent factors, such as public health, the public transportation system, and sanitation. Parasitology continues to provide insight into the mechanisms of the behavior of structural fire and its impacts.

Plagiothecium mauiense was first described in 1927 by V.F. Brotherus, based on materials from Hawaii. It has, so far been, treated as a separate species. A detailed analysis of the original material housed in the New York Botanical Garden Herbarium (NY01256708) found the specimen to be characterised by a lack of metallic lustre; concave, asymmetrical, lanceolate to lanceolate-ovate leaves, shrunken in their dry condition; a straight, not denticulate, acute to apiculate apex; elongate-hexagonal cells in irregular transverse rows, 101–131 × 15–21 µm at mid-leaf; very lax areolation, with decurrencies composed of three rows of cells. These characteristics indicate that this species is identical to the original material of P. longisetum (e.g. H-SOL 1563 011; PC0132572). Hence, we propose that P. mauiense should be recognised as a new synonym of P. longisetum. In addition, a review of P. longisetum syntypes found one (H-SOL 1563 011) to have the same date of collection as the protologue, and to possess a quite abundant gametophyte turf with well-preserved sporophytes, indicating it to be fertile. Considering the above, we propose that specimen H-SOL 1563 011 be designated the lectotype of P. longisetum.

A detailed granulometric analysis of native starches of various botanical origin was carried out: sorghum with a granule size of 3,5–21,7 μm and an average size of 11,0 μm, wheat with a granule size of 2,8–30,7 μm and an average size of 12,4 μm, rice with a granule size of 2,7–7,9 μm and an average size of 5,3 μm, triticale with a granule size of 4,0–30,7 μm and an average size of 13,2 μm, rye with a granule size of 4,9–42,8 μm and an average size of 21,2 μm, pea with a granule size of 6,1–32,3 μm and an average size of 20,4 μm, chickpea with a granule size of 6,0–25,6 μm and an average size of 14,8 μm, amaranth with a granule size of 0,5–1,5 μm and an average size of 1,1 μm, barley with a granule size of 3,0–21,4 μm and an average size of 10,9 μm, tapioca with a granule size of 2,8–31,2 μm and an average size of 10,6 μm, oat with a granule size of 3,96–14,91 μm and an average size of 7,39 μm, potato with a granule size of 7,7–60,0 μm and an average size of 21,7 μm, corn with a grain size of 3,6–19,2 μm and an average size of 9,8 μm, corn high amylose with a granule size of 3,3–11,65 μm and an average size of 7,11 μm, corn high amylopectin with a granule size of 4,26–18,26 μm and an average size of 9,94 μm, wheat from the «Shortandinskaya 95» variety With a granule size of 1,74–20,48 μm and an average size of 7,05 μm, wheat from the «Astana» variety with a granule size of 2,52–26,74 μm and an average size of 8,30 μm, wheat from the «Akmola-2» variety with a granule size of 2,43–26,22 μm and an average size of 8,11 μm. Based on the granulometric analysis of native starch, an innovative, highly effective, economical and environmentally friendly method of purposefully changing the physicochemical properties of native starches of various botanical origin was developed using the combinatorial method.

Background and aims – Confusion over the taxonomic identity of Neidium iridis (Ehrenb.) Cleve (= Navicula iridis Ehrenb.) has persisted for more than 130 years with identifications of valve shapes varying from elliptical to linear and sizes from 100 to 300 µm. This confusion can be linked to the rarity of the species and poor attention to the original line drawings of Ehrenberg. This study examines the type material of Navicula iridis and further uses additional material from North America to define the species Neidium iridis. Methods – Mica and material from Christian Gottfried Ehrenberg’s Collection were studied to examine Navicula iridis. Light and electron microscope techniques were used to document the variability of valve morphology of original material in comparison with other fossil and recent materials. Key results – Ehrenberg designated no nomenclatural type for Navicula iridis at the place of its first description, and until recently the original material was not studied. One freshwater extant locality was identified (New York, West Point) in the original 1843 publication, and in his notes and drawings. Examination of the micas and material from the type locality, showed that Navicula iridis was very rare. Two specimens were found that matched the line drawing presented by Ehrenberg. In addition, we examined Ehrenberg’s original material with SEM, as well as two other localities in North America and present LM and SEM documentation of additional valve forms. A further evaluation of the status of Neidium columnaris, Neidium maximum and an unknown taxon in relation to Neidium iridis is presented. Conclusions – The findings of this study elucidate the taxon Navicula iridis (= Neidium iridis) as described by Ehrenberg in 1843. This will assist in the identification of other large Neidium taxa which to date have been associated with Neidium iridis.

The annual publication of the Theatre Library Association is designed “to gather and disseminate scholarly articles dealing with the location of resource materials” relating to all media as well as popular entertainments, the evaluation of those resources, and to include as well “monographs of previously unpublished original material.” The volumes are slim ones, so we should not expect coverage of the many theatre collections available to scholars and practitioners, but rather a highly selective series of essays reflecting the priorities of the Association or of the individual volume editors. This certainly appears to be the case here: the 1998 volume concerns itself with eighteenth- and nineteenth-century American pleasure gardens, whereas, after a publication hiatus of three years, the 2001 volume is focused around the acquisition, scope, and use of four major archives—those of the Joseph Papp/New York Shakespeare Festival and of Lucille Lortel in the New York Public Library of the Performing Arts, the Lawrence and Lee Theatre Research Institute at Ohio State University, and the holdings of the Weill—Lenya Research Center in New York. As a consequence, the tones of the two volumes are very different, as is their utility. The first volume appears to be directed toward a disinterested readership; the second addresses those who might actually use the particular collections.
