Wood storage in a wide mountain river: case study of the Czarny Dunajec, Polish Carpathians

EARTH SURFACE PROCESSES AND LANDFORMS, Issue 12 2005
omiej Wy
Abstract Storage of large woody debris in the wide, mountain, Czarny Dunajec River, southern Poland, was investigated following two floods of June and July 2001 with a seven-year frequency. Within a reach, to which wood was delivered only by bank erosion and transport from upstream, wood quantities were estimated for eighty-nine, 100 m long, channel segments grouped into nine sections of similar morphology. Results from regression analysis indicated the quantity of stored wood to be directly related to the length of eroded, wooded banks and river width, and inversely related to unit stream power at the flood peak. The largest quantities of wood (up to 33 t ha,1) were stored in wide, multi-thread river sections. Here, the relatively low transporting ability of the river facilitated deposition of transported wood while a considerable length of eroded channel and island banks resulted in a large number of trees delivered from the local riparian forest. In these sections, a few morphological and ecological situations led to the accumulation of especially large quantities of wood within a small river area. Very low amounts of wood were stored in narrow, single-thread sections of regulated or bedrock channel. High stream power facilitated transport of wood through these sections while the high strength of the banks and low channel sinuosity prevented bank retreat and delivery of trees to the channel. Considerable differences in the character of deposited wood existed between wide, multi-thread channel sections located at different distances below a narrow, 7 km long, channellized reach of the river. Wood deposited close to the downstream end of the channellized reach was highly disintegrated and structured into jams, whereas further downstream well preserved shrubs and trees prevailed. This apparently reflects differences in the distance of wood transport and shows that in a mountain river wider than the height of trees growing on its banks, wood can be transported long distances along relatively narrow, single-thread reaches but is preferentially deposited in wide, multi-thread reaches.

Genetic variations among Mycoplasma bovis strains isolated from Danish cattle

FEMS MICROBIOLOGY LETTERS, Issue 1 2000

Abstract The genetic heterogeneity of Mycoplasma bovis strains isolated in Denmark over a 17-year period was investigated. Forty-two field strains isolated from different geographic locations and specimens, including strains from 21 herds involved in two outbreaks of M. bovis -induced mastitis, and the type strain of M. bovis (PG45T) were assayed for variations in the BglII and MfeI restriction sites in the chromosomal DNA by using the amplified fragment length polymorphism (AFLP) fingerprinting technique. The obtained genomic fingerprints consisted of 62,68 AFLP fragments in the size range of 50,500 bp. Among the analyzed strains, 18 different AFLP profiles were detected. The similarity between individual fingerprints, calculated by Dice similarity coefficient, ranged from 0.9 to 1.0. Twenty-five strains, including 23 which were isolated during two outbreaks of M. bovis -induced mastitis which occurred 2 years apart, showed indistinguishable AFLP patterns. More genetic diversity was observed among the recent strains. The similarity of the genotypes of the field strains to that of the M. bovis type strain (PG45T) was 97.7%. The results of this study have demonstrated a remarkable genomic homogeneity of Danish strains of M. bovis that were probably epidemiologically related and which have remained stable for a considerable length of time. Furthermore, this study has demonstrated that AFLP can be used for genomic fingerprinting and discrimination of M. bovis strains. [source]

Linearity in rhetorical organisation: a comparative cross-cultural analysis of newstext from the People's Republic of China and Australia

INTERNATIONAL JOURNAL OF APPLIED LINGUISTICS, Issue 2 2000
Guy RamsayArticle first published online: 3 APR 200
Second or foreign language teachers would be familiar with student comments such as, "I can't follow what they're saying!", "What are they getting at?", or "What's their point?", particularly when reading L2 texts of considerable length. This paper seeks to address the issues premised by such comments made by L2 learners of Modern Standard Chinese, within the rubric of contrastive rhetoric studies. Such studies to date have produced equivocal evidence of variation in rhetorical organisation across culturo-linguistic groups. In order to contribute to this continuing debate, this study employs the Rhetorical Structure Theory analytic framework to produce pictorial representations of lengthy Chinese and Australian news journal text. Results obtained clearly demonstrate the feasibility of using the RST framework in this kind of analysis. While the small size of the newstext corpus severely limits the generality of other findings, they give tentative support to the contrastive rhetoric hypothesis. Pedagogical implications include the benefits of promoting awareness of such cross-cultural variation within the L2 classroom. [source]

Making Sense of Theatre in the Third Reich

HISTORY COMPASS (ELECTRONIC), Issue 5 2010
Gerwin Strobl
In the crowded field of studies on Nazi Germany the role of theatre in the Third Reich continues to be a neglected subject. The reluctance to engage with the topic is particularly true among historians and is in striking contrast to the attention devoted in recent years to other branches of the arts. Yet theatre actually received lavish funding from the Nazi regime. Indeed at no time in the history of the German stage was the provision so opulent, and the Nazi leadership went to considerable lengths to maintain the theatre sector even in wartime. The neglect of the theatre therefore constitutes more of a reflection on the priorities of the historical profession than those of the Nazi regime. This article attempts to redress the balance and to explore possible reasons for the limited treatment of the subject in the existing literature. [source]
