The potential climate benefits of seaweed farming in temperate waters.

Seaweed farming is widely promoted as an approach to mitigating climate change despite limited data on carbon removal pathways and uncertainty around benefits and risks at operational scales. We explored the feasibility of climate change mitigation from seaweed farming by constructing five scenarios spanning a range of industry development in coastal British Columbia, Canada, a temperate region identified as highly suitable for seaweed farming. Depending on growth rates and the fate of farmed seaweed, our scenarios sequestered or avoided between 0.

Assessing fisheries nutrient yields: The Northwest Atlantic, 1950-2014.

Fisheries are important sources of nutrients for people, but fisheries science and management do not consider nutrient information. The result is that fisheries are conducted without knowledge of how exploited species portfolios produce nutrients, how these yields have changed over time, and how they may change in the future. Here, we develop approaches for nutrient-informed analysis, and illustrate their use by applying them to catches from northwest Atlantic fisheries from 1950 to 2014.

Causes of Early Hip Revision Vary by Age and Gender: Analysis of Data From a Statewide Quality Registry.

Background: While total hip arthroplasty (THA) is extremely successful, early failures do occur. The purpose of this study was to determine the cause of revision in specific patient demographic groups at 3 time points to potentially help decrease the revision risk.

Methods: Data for cases performed between 2012 and 2018 from a statewide, quality improvement arthroplasty registry were used.

Design and manufacturing of roller bearing polymeric cages and development of a theoretical model for predicting the roller push-out force.

In the present work, polymeric cages with 18 different pocket geometries are developed to investigate the effects of geometrical parameters and material properties on the amount of roller push-out force. An experimental setup including a specialized injection molding tool is designed and fabricated and three sets of polymeric cages are manufactured using the selected materials (PA46, PA66, PPA). Force measurements are carried out five times on each pocket and three cages for each material are tested.

Enhancing the quality of clinical supervision in nursing practice.

Clinical supervision has been an aspect of nursing practice in various forms for several years; however, it remains challenging to ensure its widespread implementation across healthcare organisations. There is an increasingly evident need for formalised support in nurses' busy practice settings, so it is important to improve the quality of clinical supervision in healthcare. This will also assist nurses in providing evidence of their continuing professional development as part of revalidation.

Equipping an urban hospital police and security team with Narcan: part two.

In their article in the last issue of the Journal, the authors reported on their health system's decision to equip their security officers with Narcan, the nasal-spray form of naloxone, and train them to use the drug to revive patients and non-patients overdosed with heroin or other life-threatening opioids. The decision, they said, was prompted with an increase in individ- uals who may come to the hospital ' 32 buildings and over 130 offsitefa- cilities to "shoot up" themselves. In this follow-up report, they describe what has happened in the seven months since the policy was begun-- how many times Narcan was utilized; what happened during such incidents; lessons learned; and how comfortable security officers are with this new re- sponsibility.

Optimal Mortgage Refinancing: A Closed Form Solution.

We derive the first closed-form optimal refinancing rule: Refinance when the current mortgage interest rate falls below the original rate by at least [Formula: see text] In this formula (.) is the Lambert -function, [Formula: see text] is the real discount rate, is the expected real rate of exogenous mortgage repayment, σ is the standard deviation of the mortgage rate, is the ratio of the tax-adjusted refinancing cost and the remaining mortgage value, and is the marginal tax rate. This expression is derived by solving a tractable class of refinancing problems.

Coaching for clinicians.

CLINICAL SUPERVISION (CS) continues to be promoted across the UK as a legitimate work based activity for nurses, midwives and health visitors who work in the NHS. It also receives attention from allied health professions.

Skin reflectance of children and young adults of Aymara ancestry.

The skin reflectance of 556 Andean Indians of Aymara ancestry (305 males, 251 females; 10.0-29.9 yr) residing in La Paz, Bolivia (average altitude of about 3,600 m) is described.
