Door closers are widely used for doors in commercial buildings, not only for safety purposes but also for reducing the airflow through door openings. This study aimed to develop a method for quickly assessing, in the design phase, the heating and cooling energy cost saving from using an effective door closer. The method developed in this study consists of a stop angle model, airflow model, and ...

Effective power saving mechanism is the most significant issue for extending the lifetime of mobile stations in wireless metropolitan area network (MAN). In this paper, we propose an effective method to analyze the system performance of the power saving class type II in IEEE 802.16e. We present a queueing model with two kinds of vacation mechanisms to capture the working principle of the networ...

BACKGROUND & AIMS Despite the clinical benefits of using standard (non-disease specific) oral nutritional supplements (ONS) in the community and care homes, there is uncertainty about their economic consequences. METHODS A systematic review was undertaken according to recommended procedures to assess whether ONS can produce cost savings and cost-effective outcomes. RESULTS 19 publications w...

BACKGROUND Low molecular weight heparins hold several advantages over unfractionated heparin including convenience of administration. Enoxaparin is one such heparin licensed in the UK for use in unstable coronary artery disease (unstable stable angina and non-Q wave myocardial infarction). In these patients, two large randomised controlled trials and their meta-analysis showed small benefits fo...

BACKGROUND Seven-valent pneumococcal conjugate vaccine (PCV7) had profound public-health impacts and is considered cost-effective and potentially cost saving. Two new PCVs have been launched, a 10-valent vaccine (PCV10) and a 13-valent vaccine (PCV13). We examined public-health and economic impacts of PCV pediatric national immunization programs (NIPs) in Germany, Greece, and the Netherlands. ...

In spite of controversies, dialyzer reuse has remained an integral part of hemodialysis because of lower cost, good overall safety record, and improved membrane biocompatibility. Reuse declined in developed countries from the beginning of this century because of mass production of hemodialyzers at favourable price with better biocompatible membrane. Abandoning dialyzer reuse became challenging ...

Job losers exhibit significant heterogeneity in wealth holdings and in the marginal propensity to consume transitory income. We consider potential sources of this heterogeneity, whether (some of) the unemployed face borrowing constraints, and the implications of this heterogeneity for unemployment insurance. We show theoretically how the optimal benefit can depend significantly on borrowing con...

BACKGROUND Pre-exposure prophylaxis (PrEP) with tenofovir and emtricitabine prevents HIV infections among men who have sex with men (MSM). PrEP can be given on a daily or intermittent basis. Unfortunately, PrEP is not reimbursed in most European countries. Cost-effectiveness analyses of PrEP among MSM in Europe are absent but are key for decision makers to decide upon PrEP implementation. MET...
