Impact of Positive Lifestyle Behaviors on Direct Health Care Cost Savings for Low Back Pain

Arthritis Care &Research, EarlyView.
Objective This study aimed to investigate the relationship between a previously purpose‐developed lifestyle behavior scale and health care cost savings related to low back pain (LBP). Methods This longitudinal study used data from the Australian Twin Back (AUTBACK) study. LBP and lifestyle behavior measures were collected at baseline. Physical activity

Addressing Economic Insecurities Can Improve Patient‐Reported Outcomes in Lupus

Arthritis Care &Research, Accepted Article.
Background Economic insecurities, such as food, housing, transportation, and financial challenges, are modifiable risk factors and influence patient‐reported outcomes (PROs) in systemic lupus erythematosus (SLE). We examined: 1) associations between economic insecurities and PROs; 2) the impact of screening and addressing economic insecurities during ...

Comparison of simulation modeling and satellite techniques for monitoring ecological processes [PDF]

In 1985 improvements were made in the world climatic data base for modeling and predictive mapping; in individual process models and the overall carbon-balance models; and in the interface software for mapping the simulation results. Statistical analysis

Biospheric context of Siberian development [PDF]

, 2008
Productivity of ecosystems surrounding a city is important for supporting its activities in a sustainable way. The total terrestrial net primary production (NPP) shows biosphere potential to supply primary food energy source for all non-autotrophic ...

Rheocasting versus Die Casting: An Insight into the Low‐Cycle Fatigue Behavior of AlSi7Mg0.6

Advanced Engineering Materials, EarlyView.
The study compares rheocast lightweight components with high‐pressure die cast materials regarding microstructure and fatigue behavior. Rheocast process offers higher efficiency due to lower casting temperatures. Despite some microstructural differences, both processes show similar strengths (yield strength 125 MPa, tensile strength 240 MPa).

Primary productivity in Bahr Al-Najaf Depression Reservoir/Iraq

Kufa Journal for Agricultural Sciences, 2018
The primary productivity was calculated depending on pelagic and benthic biomass. Monthly samples were obtained from four study stations (February 2015 to January 2016). The pelagic primary productivity values were ranged between1.26 mg. cm-2.

Comparative Ecological and Physiological Characteristics of the Response of Oak (Quercus robur L.) Seed Stands to Forest Growth Conditions

Лесной журнал
A comprehensive retrospective ecological and physiological analysis of tabular data on the dry mass of stands of the genus Quercus aged from 10–20 to 140–200 years has been carried out in order to convert them into quantitative indices of the functioning

Global evidence on nitrogen saturation of terrestrial ecosystem net primary productivity

Environmental Research Letters, 2016
The continually increasing nitrogen (N) deposition is expected to increase ecosystem aboveground net primary production (ANPP) until it exceeds plant N demand, causing a nonlinear response and N saturation for ANPP.

Primary Productivity was Limited by Electron Donors Prior to the Advent of Oxygenic Photosynthesis [PDF]

, 2019
To evaluate productivity on the early Earth before the advent of oxygenic photosynthesis, we integrated estimates of net primary production by early anaerobic metabolisms as limited by geological fluxes of key electron donor compounds, phosphate, and ...
