BACKGROUND HIV viral load testing as a component of antiretroviral therapy monitoring is costly. Understanding the full costs and the major sources of inefficiency associated with viral load testing is critical for optimizing the systems and technologies that support the testing process. The objective of our study was to estimate the costs associated with viral load testing performed for antire...

cylindrical thin-walled tubes due to construction and easy installation, high energy absorption capacity are used in the automotive industry as an impact energy absorber. however, the main weakness of cylindrical tubes is in the high initial peak load. therefore, in this paper, to overcome this weakness, a buckling initiator is used at the top of the tube. this buckling initiator is a steel rod...

D evelopers typically measure a Web application’s quality of service in terms of response time, throughput, and availability. Poor QoS translates into frustrated customers, which can lead to lost business opportunities. At the same time, company expenditures on a Web site’s IT infrastructure are a function of the site’s expected traffic. Ideally, you want to spend enough, and no more, allocatin...

A method has been developed for preparing load models for power flow and stability. The load modeling (LOADMOD) computer software transforms data on load class mix, composition, and characteristics into the from required for commonly–used power flow and transient stability simulation programs. Typical default data have been developed for load composition and characteristics. This paper defines ...

OBJECTIVES Kenya is one of the first African countries to scale up a national HIV viral load monitoring program. We sought to assess program scale up using the national database and identify areas for systems strengthening. METHODS Data from January 2012 to March 2016 were extracted from Kenya's national viral load database. Characteristics of 1,108,356 tests were assessed over time, includin...

1. Methods not clear. No methods described, and no primary outcomes described. The method section was revised to describe the method and primary outcomes. In a controlled trial on PITC (Cape Town, 2007), we compared HIV follow-up care for a nested cohort of 930 HIV-positive patients. We cross-referenced HIV testing and laboratory records to determine access to CD4 and viral load testing as prim...

Reinforced concrete (RC) slabs exhibit complexities in their structural behavior under load due to the composite nature of the material and the multitude and variety of factors that affect such behavior. Current methods for determining the load-deflection behavior of reinforced concrete slabs are limited in scope and are mostly dependable on the results of experimental tests. In this study, an ...

For all that it is a common topic of conversation and concern among people and organizations that build or depend on web-based applications, testing a website in such a way that the test can reliably predict performance is still often more of an art than a science. More than a few brilliant minds have dedicated their careers to this complex topic. Several have published detailed and mathematica...

All hospitals must have an emergency power testing program that includes generator load testing and emergency power supply system maintenance. This document examines a management program that uses lessons learned from an emergency power testing program to improve the hospital's facilities and training.
