Naphthenic acids (NAs) are natural constituents in many petroleum sources, including bitumen in the oil sands of Northern Alberta, Canada. Bitumen extraction processes produce tailings waters that cannot be discharged to the environment because NAs are acutely toxic to aquatic species. However, aerobic biodegradation reduces the toxic character of NAs. In this study, four commercial NAs and the...

We examined the psychometric properties of the Novaco Anger Scale-Provocation Inventory (NAS-PI, 1994 version) in Dutch violent forensic psychiatric patients and secondary vocational students. A confirmatory factor analysis of the subscale structure of the NAS was carried out, reliability was investigated, and relations were calculated between NAS-PI scores and other measures of personality tra...

Background Brain-derived neurotrophic factor (BDNF) is a type of growth factor that promotes growth and survival of neurons. Fetal exposure to opiates can lead to postnatal withdrawal syndrome, which is referred as neonatal abstinence syndrome (NAS). Preclinical and clinical studies have shown an association between opiates exposure and alteration in BDNF expression in the brain and serum level...

We present new implementations and results for the NAS Parallel Benchmarks 2 suite. The suite currently consists of seven programs. Of these LU, SP, BT, MG and FT have previously been released. Here we describe implementations of EP and IS, as well as a rewritten version of FT that corrects some problems with the original release.

from Directly Attached (DAS) to Storage Area Networks (SAN). Along the way, Sun in 1984 invented NFS, and Network Area Storage (NAS) was born. Since then other NAS protocols have been added, most notably the Windows-based Server Message Block (SMB), a.k.a. CIFS. But throughout the history of storage, NAS has been regarded as poorly performing and unreliable compared to SAN and DAS. Certainly Ne...

N-acetyl serotonin (NAS) as a melatonin precursor has neuroprotective actions. Nonetheless, it is not clarified how NAS protects neuronal cells against oxidative stress. Recently, we have reported that N-palmitoyl serotonins possessed properties of antioxidants and neuroprotection. Based on those, we hypothesized that NAS, a N-acyl serotonin, may have similar actions in oxidative stress-induced...

Cloud architectures are moving away from a traditional data center design with SAN and NAS attached storage to a more flexible solution based on virtual machines with NAS attached storage. While VM storage based on NAS is ideal to meet the high scale, low cost, and manageability requirements of the cloud, it significantly alters the I/O profile for which NAS storage is designed. In this paper, ...

BACKGROUND Novel agents (NAs) such as thalidomide and bortezomib have been administered in combination with autologous stem-cell transplantation (ASCT) to effectively treat multiple myeloma (MM). However, whether NAs perform better as induction treatments prior to transplantation, or as post-transplant maintenance therapies remains unclear. METHODS We retrospectively analyzed 106 consecutive ...
