A proposed diachronic revision of Late Quaternary time-stratigraphic classification in the eastern and northern Great Lakes area
The AA. present the diachronic nomenclature for finer subdivisions of time and events since the penultimate glaciation (last 130,000 years), recognized in the eastern and northern Great Lakes area centered on Ontario. A deliberate attempt was made
Lichens: lichenometric dating of diachronous surfaces
This software is designed to facilitate the interpretation of large samples of lichen sizes obtained from diachronous surfaces. The lichen sizes are obtained by recording the longest axis of the largest single lichen on each boulder. The central aim
Geschäftsstrassen als Freizeitraum. Synchrone und diachrone Uberlagerung von Versorgungs-und Freizeitfunktion, dargestellt an Beispielen aus Nürnberg. (Retail streets as leisure space. Synchronous and diachronous superposition of provision
Outlines the strengths and weaknesses of different ways that geographers organize time : temporal cross-sections; synchronic cross-sections; diachronic subsections; temporal integration. - (DWG)
Based on the non-diachronic nature of loess-paleosol sequences, a paleosol dating method is suggested. The origin of the modern Yellow River drainage system is studied. Correlation of loess, paleosol, and aquatic sediment sequences of China
This excellent study uses a diachronic approach to examine the transformations in the Hunza Valley. External interventions brought by the Karakoram Highway have changed the internal structure and economic conditions. Grazing high pastures has
The varied types of modern deposit of the present-day Southern Bight are used as a partial guide for a review of the diachronous deposits of the Holocene marine transgression. The flooding of the barrier separating the Southern Bight from the North
Case studies a different scales show that interesting results can be obtained from diachronic studies of the relations between climate and agriculture. A systematic study of deviations from trends for agricultural index numbers during the last

This paper illustrates a procedure aimed at estimating diachronically soil sealing in suburban areas by using cartographical and statistical data. The procedure was applied (1949-2006) to the metropolitan area of Rome. Random sites were chosen
. The history of the discipline was divided for the diachronic analysis in seven periods while the realm of the settlement research was divided into four research areas. - (DG)
are inferred from the geological evidence : rapid, episodic and slow. They indicate that Antarctic palaeo-ice-streams did not respond uniformly to external forcing at the end of the last glacial cycle. Rather, their diachronous retreat reflects the dominance
In this paper, diachronic and event classifications are proposed for the Great Lakes region. Well-established names, including Wisconsin, Sangamon, and Illinois, are used at the episode (or glaciation/interglaciation) rank without significant
it possible to carry out accurate datings. The diachronisms among different infilled valleys may be caused by both human activity and complex responses of the system. This paper synthesizes existing knowledge and a climatic model for the late Holocene, and its
hazards of the more mature fans. This study demonstrates that complications arise from differences in the timing of fan inititation, and with the degree of diachroneity.

frequently oscillate, producing pronounced diachronism. Bottom melting removes all debris prior to calving at the ice front so that, ice shelves do not play a part in deposition in the open ocean| 2. Outlet glaciers, in contrast, have high sediment content
On the synchronic level, the analysis shows which causes affect subjects according to age and sex, and indicates in particular the causes of greater than average masculine mortality. As far as the diachronic level is concerned, the period
