Bronchial asthma: Advice for patients traveling to high altitude

open access: yes, 2009
This article examines the possibility of travelling to altitude for patients suffering from bronchial asthma. The mountain environment, the adaptations of the respiratory system to high altitude, the underlying pathophysiologies of asthma and the ...

Changes in body composition during acute exposure to high altitude is related to acute mountain sickness

open access: yesTravel Medicine and Infectious Disease
Background: Acute hypoxia exposure leads to a high incidence of acute mountain sickness (AMS) and changes in body composition, while the relationship between body composition and AMS remains unclear.

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

open access: yesChemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

Arterial oxygen saturation and hemoglobin mass in postmenopausal untrained and trained altitude residents

open access: yes, 2007
Because of lacking ventilatory stimulation by sex hormones in postmenopausal women (PW), one might expect a lowered arterial oxygen saturation (S(O(2))) in hypoxia and therefore a stronger erythropoietic reaction than in young women (YW). Nine untrained (

Comparison of Dried Blood Spot Sampling Methods for RNA‐Based Biomarker Measurement in Anti‐Doping

open access: yesDrug Testing and Analysis, EarlyView.
This study demonstrates that RNA‐based biomarkers of erythropoiesis, ALAS2 and CA1, can be reliably quantified across commonly used DBS sampling matrices, including venous and capillary blood spotted on cellulose cards and the Tasso‐M20 device. ABSTRACT Dried blood spot (DBS) sampling offers logistical advantages, but it remains unexplored whether ...

Permeability of granite from a shallow buried mountain pipe gallery tunnel under unloading confining pressure

open access: yesDeep Underground Science and Engineering, EarlyView.
Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

Dynamic geo‐hydrogeological monitoring‐driven situational awareness for real‐time floor water inrush risk prediction in deep mining

open access: yesDeep Underground Science and Engineering, EarlyView.
The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

open access: yesDeep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Magnetic local time dependency on cusp ion velocity dispersions in the mid-altitude cusp

open access: yes, 2001
Observations of cusp ion velocity dispersions made by the TIMAS instrument on the Polar spacecraft in the mid-altitude cusp during intervals of northward interplanetary magnetic field (IMF) reveal a clear ordering with magnetic local time (MLT).
