Frozen ground and snow cover monitoring in the South Shetland Islands, Antarctica: Instrumentation, effects on ground thermal behaviour and future research

Cuadernos de Investigación Geográfica, 2016
The study of the thermal behavior of permafrost and active layer on the South Shetland Islands, in the western side of the Antarctic Peninsula (Antarctica), has been our research topic since 1991, especially after 2006 when we established different ...

Framing National Education in Hong Kong: A frame analysis of power dynamics in stakeholders' competing narratives

British Educational Research Journal, EarlyView.
Abstract This article examines how national education in Hong Kong functions as a contested arena in which state and non‐state actors struggle over the meaning of citizenship, identity and schooling. Using inductive frame analysis of 319 news articles (2020–2025) from five Chinese‐ and English‐language outlets, it identifies diagnostic, prognostic and ...

Cellular-Automata model for dense-snow avalanches [PDF]

, 2007
This paper introduces a three-dimensional model for simulating dense-snow avalanches, based on the numerical method of cellular automata. This method allows one to study the complex behavior of the avalanche by dividing it into small elements, whose ...

Growth response of temperate mountain grasslands to inter-annual variations in snow cover duration [PDF]

Biogeosciences, 2015
Abstract. A remote sensing approach is used to examine the direct and indirect effects of snow cover duration and weather conditions on the growth response of mountain grasslands located above the tree line in the French Alps. Time-integrated Normalized Difference Vegetation Index (NDVIint), used as a surrogate for aboveground primary productivity, and

Where Do We Fit? Reflections on Research Interview Practice, Project Design, and Interpretation**

Berichte zur Wissenschaftsgeschichte, EarlyView.
What is special about historical research interviews in the history of science, technology, and medicine, and how do they compare to the tools of oral historians and social scientists? This essay reflects on three interview projects I have undertaken, each taking a distinct shape.

Changes in extreme nival conditions in Poland during the second half of the 20th century

Meteorologische Zeitschrift, 2008
The two main objectives of this study are: 1. to assess the scale of extreme nival conditions in Poland; 2. to provide a fragmentary, regional verification of the IPCC thesis of the increasing frequency of extreme atmospheric phenomena during recent ...

Seasonal snow cover indicators in coastal Greenland from in situ observations, a climate model, and reanalysis [PDF]

The Cryosphere
Seasonal snow cover has important climatic and ecological implications for the ice-free regions of coastal Greenland. Here we present, for the first time, a dataset of quality-controlled snow depth measurements from nine locations in coastal Greenland ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Snow cover on the Lagonaky high plateau (Western Caucasus)

Лëд и снег, 2017
The paper presents characteristics of a snow cover observed on the Lagonaky high plateau (the Western Caucasus) in the interfluve of the rivers Belaya and Pshekha along two snow-measuring courses. The period of observations is 1973–2015, and the altitude
