Data provenance is essential for debugging query results, auditing data in cloud environments, and explaining outputs of Big Data analytics. A well-established technique is to represent provenance as annotations on data and to instrument queries to propagate these annotations to produce results annotated with provenance. However, even sophisticated optimizers are often incapable of producing ef...

In vitro studies have been carried out to establish the nutritional differences between crude and refined vegetable oils; however, the impact of the consumption of these foods on metabolism, in particular the effect of buriti oil, needs to be further evaluated. The aim of this study was to evaluate the biochemical and murine parameters and the vitamin A and E status in young rats fed with diets...

We describe the set-up for an electrical muscle stimulation device based on near-infrared spectroscopy (NIRS), designed for use as a brain-computer interface (BCI). Employing multi-channel NIRS, we measured evoked cerebral blood oxygenation (CBO) responses during real motor tasks and motor-imagery tasks. When a supra-threshold increase in oxyhemoglobin concentration was detected, electrical sti...

INTRODUCTION HIV disclosure to a steady sexual partner (SSP) is important both in preventing HIV transmission and improving the quality of life of people living with HIV (PLHIV). Its determinants have been poorly investigated in the Democratic Republic of the Congo. The study objective was to determine factors independently associated with voluntary disclosure to one's SSP in PLHIV receiving se...

The federal government’s debt has increased dramatically in the past few years, and large annual budget deficits will probably continue indefinitely under current laws or policies. If current laws remain unchanged, deficits will total roughly $7 trillion over the next 10 years, the Congressional Budget Office (CBO) projects; if certain policies that are scheduled to expire under current law wer...

BACKGROUND The Healthy Carolinians community microgrants project provided microgrants to community-based organizations (CBOs) across North Carolina. These grants were made to serve as a catalyst to engage the CBOs in health promotion activities that addressed Healthy People 2010 objectives. The purpose of this initiative was to increase the awareness of Healthy People 2010 objectives, mobilize ...

Sputtered-deposited Zn(O,S) is an attractive alternative to CdS for Cu(In, Ga)Se 2 (CIGS) thin-film solar cells' buffer layer. It has a higher band gap and thus allows greater blue photon collection to achieve higher photon current. The primary goal of the thesis is to investigate the effects of the secondary barrier at the buffer-absorber interface on the distortions to current-voltage (J-V) c...

BACKGROUND Harm reduction case management relies on client-identified goals to drive the provision of care in order to "meet clients where they are at". This research measured the level of agreement between client-identified needs and agency-provided services at a community based organization (CBO) in Washington DC by examining: (1) the services clients most often identified, (2) the services m...
