Intensity Calibration in the Presence of a Disturbing Effect Dependent on Wavelength [PDF]

open access: yesSymposium - International Astronomical Union, 1994
Conversion of light detector signals to intensity values is one of the most important factors influencing precision of spectroscopic observations. Most of the classical light detectors used in astronomical practice are more or less nonlinear.

Measurement of changes in marine benthic ecosystem function following physical disturbance by dredging [PDF]

open access: yes, 2012
Measuring the impact of physical disturbance on macrofaunal communities and sediment composition is important given the increased demand for the exploitation and disturbance of marine ecosystems.

Ice disturbance intensity structures benthic communities in nearshore Antarctic waters [PDF]

open access: yes, 2007
Ice scouring is one of the 5 most significant natural forces acting on ecosystems, yet very few data exist linking the intensity of ice disturbance with parameters of benthic community structure.

Consequences of plateau pika disturbance on plant-soil carbon and nitrogen in alpine meadows

open access: yesFrontiers in Plant Science
The presence of burrowing mammals can have extensive effects on plants and soils, creating bare soil patches in alpine meadows and potentially altering plant-soil carbon (C) and nitrogen (N). This study focuses on the plateau pika (Ochotona curzoniae) to

Coastal dynamic geomorphology under high intensity disturbance: research progress and perspectives

open access: yesShui kexue jinzhan, 2023
The coastal zone is the strongest interaction zone among the land, ocean, and atmosphere, and it is also the area that is most affected by global climate, sea-level change, and human activities.The dynamic process of the coastal zone has obvious ...

Testing the intermediate disturbance hypothesis: response of fouling communities to various levels of emersion intensity [PDF]

open access: yes, 2004
Connell¹s intermediate disturbance hypothesis (IDH) postulates that diversity peaks at an intermediate level of disturbance frequency or intensity. To test the validity of this concept for the species-poor marine hard-bottom community of the Western ...

Identifying Patterns of Hospitalizations Among Childhood Cancer Survivors: A Population‐Based Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Childhood cancer survivors (CCSs) experience more hospitalizations than the general population. We aimed to identify distinct hospitalization patterns among Queensland CCSs and the associated characteristics. Methods Cases (aged ≤14 years) diagnosed between 1995 and 2019 while residents of Queensland were identified through the ...

Differences in functional traits of herbaceous plants in Sanjiang plain wetland under human disturbance gradient and their response strategies to environmental changes

open access: yesFrontiers in Plant Science
Using the Honghe Nature Reserve in the Sanjiang Plain as a case study, this research tests the central hypothesis that increasing anthropogenic disturbance intensity shifts the ecological strategies of dominant plant species along a resource-conservative

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
