To assess the ability of the nose to warm and humidify inhaled air, we developed a nasopharyngeal probe and measured the temperature and humidity of air exiting the nasal cavity. We delivered cold, dry air (19-1 degrees C, <10% relative humidity) or hot, humid air (37 degrees C, >90% relative humidity) to the nose via a nasal mask at flow rates of 5, 10, and 20 l/min. We used a water gradient a...

Cenozoic plant relicts are those groups that were once widespread in the Northern Hemisphere but are now restricted to some small isolated areas as a result of drastic climatic changes. They are good proxies to study how plants respond to climatic changes since their modern climatic requirements are known. Herein we look at the modern distribution of 65 palaeoendemic genera in China and compare...

Representations of femininity in video games and other media are often discussed with reference to the most popular games, their protagonists and their sexist predicament. This framing leaves in shadow other dimensions. We aim to identify some of them and to open a broader horizon for examining and designing femininity and gender in games. To this end we look into games with creative portrayals...

Ambient particles may undergo modifications to their chemical composition as a consequence of climatic variability. The determination of whether these changes modify the toxicity of the particles is important for the understanding of the health effects associated with particle exposure. The objectives were to determine whether low levels of particles promote cardiopulmonary effects, and to asse...

The Amazon Basin is dominated by convective rainfall with significant spatial and diurnal variability. Diurnal seasonal distributions of events were determined from Cloud Top Temperature (CTT) between January 2008 December 2010 in city Belém-PA. decis technique was used to select the most intense (rainfall rate ≥ 15 mm h–1), which subsequently, subclassified into deep convection (DCE) shallow (...

In semiarid or arid conditions, the change of root-zone soil moisture can be almost instantaneously reflected by vegetation through biophysical process. This study investigated feasibility of mapping root-zone soil moisture using MODIS-derived NDVI via statistic approach at three sites (New Mexico, Arizona, and Texas) selected from the Soil Climate Analysis Network (SCAN). These three sites rep...

A severe outbreak of dermatophilosis occurred in 1985 in a herd of Brahman cows imported from Martinique in Guadeloupe in July 1983. Little was known on this disease in Guadeloupe until then, for the local zebu breed is naturally highly resistant to diseases transmitted by ticks or associated with them. Conditions of appearance and development of the disease were studied in relation with herd m...

Influence of long-term changes in climate and CO2 concentration on intrinsic water-use efficiency (iWUE), defined as the ratio between net photosynthesis (A) and leaf conductance (g), and tree growth remain not fully revealed in humid subtropical China, which is distinct from other arid subtropical areas with dense coverage of broadleaf forests. This study presented the first tree-ring stable c...
