Acid deposition and repeated biomass harvest have decreased
soil calcium (Ca) availability in many temperate forests worldwide, yet
existing methods for assessing available soil Ca do not fully characterize
soil Ca forms. To account for discrepancies in ecosystem Ca budgets, it
has been hypothesized that the highly insoluble biomineral Ca...
OBJECTIVE: To evaluate the effectiveness of a 3-month treadmill desk intervention in eliciting changes in physical activity and sedentary behavior among overweight/obese office workers. METHODS: A randomized controlled trial was conducted among overweight/obese office workers (n=41; mean age = 40.1 ± 10.1 years) at a private workplace. Participants were randomly...
CONTEXT: In older adults with multiple conditions, medications may not impart the same benefits seen in patients who are younger, or without multi-morbidity. Furthermore, medications given for one condition may adversely affect other outcomes. Beta-blocker (β-Blocker) use with coexisting cardiovascular disease (CVD) and chronic obstructive pulmonary disease (COPD) is such...
A radioactive particulate release experiment to produce a near-field ground deposition representative of small-scale venting from an underground nuclear test was conducted to gather data in support of treaty capability development activities. For this experiment, aCO₂‐driven “air cannon” was used to inject ¹⁴⁰La, a radioisotope of lanthanum with 1.7‐d half-life...
BACKGROUND: In the prenatal period, women can have sustained contact with nurses and other clinicians, forming relationships that are likely to be health enhancing both for the woman and her unborn child. Yet first trimester care use in Oregon dropped noticeably over the past decade. In comparison with Washington State,...
OBJECTIVE: Pharmacokinetic interactions exist between combined
oral contraceptives and protease inhibitors (PI). However, such
information is lacking for progestin-only oral contraception. We
sought to define the steady-state pharmacokinetic interaction between
norethindrone (NET) and PI in HIV-infected women.
METHODS AND DESIGN: We conducted an open-label, prospective,
nonrandomized trial to characterize the...
Open Educational Resources (OER) are increasingly used
in the higher education landscape as a solution for a variety of
copyright, publishing and cost-prohibiting issues. While OERs are
becoming more common, reports of usability tests that evaluate how
well learners can use them to accomplish their learning tasks have
lagged behind....
The paper describes for the first time the analysis of the structure of compressed wood using computed tomography. The anatomical structures of Douglas-fir and hybrid poplar before and after densification with the Viscoelastic Thermal Compression (VTC) process were described by pore size distributions and mean pore sizes and compared. The...
This publication is prepared to assist processors of specialty food, distributors, vendors, and food regulators of backgrounds and experience in finding specific information on producing safe specialty food products. This publication discusses the unique characteristics of specialty foods, identifies food safety concerns in specialty foods production, and provides examples of...
Land-use regulations are contentious everywhere because of their potential negative effects on private property values. In recent years, “pay or waive” compensation legislation has been passed in a number of U.S. states, requiring governments to compensate property owners for losses due to land-use regulations or grant exemptions from the regulations...
