Heteroatom-doped nanoporous carbons are now emerging as alternatives to platinum and its alloys as electrocatalysts to facilitate oxygen reduction reaction in metal-air batteries and fuel cells. However, the synthesis of nanoporous carbons usually involve in complicated procedures and intensive chemicals, which may dramatically raise their manufacture cost that even surpasses that of precious platinum. Herein, we demonstrate the single-step, chemical-free fabrication of N, P dualdoped honeycomb carbon that has hierarchically porous structure and oxygen electrocatalysis activity close to the benchmark Pt/C...

A water recycling system was installed at the Nova Scotia Hospital Central Laundry in Dartmouth, Nova Scotia in the spring of 2014. The consequent reductions in the consumption of water and steam at this facility have been measured over a 20-month period and are presented here in nominal units and as a financial analysis. Cumulative savings over this period have been calculated to be $351,567, representing a 53% annual return on investment after accounting for annual operating and maintenance costs.

Although the impact the environment can have on human health is well understood, the healthcare system's impact on the environment is a topic that's only been explored since the mid-1990s. More recent has been a realization of the risks that climate change poses to health and healthcare. Although there are numerous direct benefits for hospitals adapting environmental sustainability programs, this article examines how the systemic approach taken by the University Health Network's (UHN) Energy & Environment program not only improves the hospital's environmental performance and provides significant cost savings but also supports several areas of focus that are part of UHN's current journey of renewal...

For new technology and innovation such as precision medicine to become part of the solution for the fiscal sustainability of Canadian Medicare, decision-makers need to change how services are priced rather than trying to restrain emerging technologies like precision medicine for short-term cost savings. If provincial public payers shift their thinking to be public purchasers, value considerations would direct reform of the reimbursement system to have prices that adjust with technologically driven productivity gains...

The purpose of tinnitus retraining therapy (TRT) is to induce habituation, first of the reaction to the tinnitus signal, and subsequently to habituate the perception of tinnitus itself. Habituation of sound is achieved through sound treatment which involves the use of low-level broadband noise mainly through noise maskers. Noise maskers are costly hence there is a need to find an alternate source of noise like MP3 and mobile phones. The goal of present study was to find out whether persons with tinnitus may be successfully treated with TRT using sound treatment from the noise presented through mobile phones...

Space heating accounts for the largest energy end-use of buildings that imposes significant burden on the society. The energy wasted for heating the empty space of the entire building can be saved by passively heating the immediate environment around the human body. Here, we demonstrate a nanophotonic structure textile with tailored infrared (IR) property for passive personal heating using nanoporous metallized polyethylene. By constructing an IR-reflective layer on an IR-transparent layer with embedded nanopores, the nanoporous metallized polyethylene textile achieves a minimal IR emissivity (10...

INTRODUCTION: A retained placenta is diagnosed when the placenta is not delivered following delivery of the baby. It is a major cause of postpartum haemorrhage and treated by the operative procedure of manual removal of placenta (MROP). METHODS AND ANALYSIS: The aim of this pragmatic, randomised, placebo-controlled, double-blind UK-wide trial, with an internal pilot and nested qualitative research to adjust strategies to refine delivery of the main trial, is to determine whether sublingual glyceryl trinitrate (GTN) is (or is not) clinically and cost-effective for (medical) management of retained placenta...

BACKGROUND: Tension band wiring (TBW) and locked plating are common treatment options for Mayo IIA olecranon fractures. Clinical trials have shown excellent functional outcomes with both techniques. Although TBW implants are significantly less expensive than a locked olecranon plate, TBW often requires an additional operation for implant removal. To choose the most cost-effective treatment strategy, surgeons must understand how implant costs and return to the operating room influence the most cost-effective strategy...

REVIEW
Abdullah A Gibriel, Ola Adel
Genetic variants have been reported to cause several genetic diseases. Various genotyping assays have been developed for diagnostic and screening purposes but with certain limitations in sensitivity, specificity, cost effectiveness and/or time savings. Since the discovery of ligase chain reaction (LCR) in the late nineties, it became one of the most favored platforms for detecting these variants and also for genotyping low abundant contaminants. Recent and powerful modifications with the integration of various detection strategies such as electrochemical and magnetic biosensors, nanoparticles (NPs), quantum dots, quartz crystal and leaky surface acoustic surface biosensors, DNAzyme, rolling circle amplification (RCA), strand displacement amplification (SDA), surface enhanced raman scattering (SERS), chemiluminescence and fluorescence resonance energy transfer have been introduced to both LCR and ligation based amplifications to enable high-throughput and inexpensive multiplex genotyping with improved robustness, simplicity, sensitivity and specificity...

The treatment of hepatitis C virus in monoinfected and HIV-coinfected patients has greatly changed over recent years as a result of the introduction of direct-acting antiviral agents (DAAs), which have revolutionized clinical outcomes and led to sustained virological response rates above 90-95%. The discovery of new molecules and the subsequent competition between pharmaceutical companies, together with the negotiated price policies pursued by many national health systems, have led to a gradual reduction in the cost of DAAs, and expand their use to an increasing number of patients, including those with mild liver damage...

The essays in this issue of The Journal of Medicine and Philosophy explore an innovative voucher program for encouraging kidney donation. Discussions cluster around a number of central moral and political/theoretical themes: (1) What are the direct and indirect health care costs and benefits of such a voucher system in human organs? (2) Do vouchers lead to more effective and efficient organ procurement and allocation or contribute to greater inequalities and inefficiencies in the transplantation system? (3) Do vouchers contribute to the inappropriate commodification of human body parts? (4) Is there a significant moral difference between such a voucher system and a market in human organs for transplantation? This paper argues that while kidney vouchers constitute a step in the right direction, fuller utilization of market-based incentives, including, but not limited to, barter exchanges (e...

Pressure ulcers represent a major current health problem and cause an important economic impact on the health care system. Most studies on the prevention of pressure ulcers have been carried out in hospital contexts, with respect to the use of hyperoxygenated fatty acids, and to date no studies have specifically examined the use of olive oil-based treatments. AIM: To evaluate the cost of using extra virgin olive oil, rather than hyperoxygenated fatty acids, in the prevention of pressure ulcers among persons with impaired mobility and receiving home care...

This technical correspondence considers finite-time synchronization of dynamical networks by designing aperiodically intermittent pinning controllers with logarithmic quantization. The control scheme can greatly reduce control cost and save both communication channels and bandwidth. By using multiple Lyapunov functions and convex combination techniques, sufficient conditions formulated by a set of linear matrix inequalities are derived to guarantee that all the node systems are synchronized with an isolated trajectory in a finite settling time...
