BACKGROUND Driver error and inadequate skill are common critical reasons for novice teen driver crashes, yet few validated, standardised assessments of teen driving skills exist. The purpose of this study is to evaluate the construct and criterion validity of a newly developed Simulated Driving Assessment (SDA) for novice teen drivers. METHODS The SDA's 35 min simulated drive incorporates 22 ...

Changes in the composition of fatty acids (FA) were determined in lipid extracts isolated from developing ovaries containing ovules and developing seeds of Echium vulgare L. The samples were collected successively over 20 days beginning with the first day after flowering. The contents of the n-6 FA family members, i.e., γ-linolenic (GLA) (C18 : 3) and linoleic (LA) (C18 : 2) acids changed in a ...

OBJECTIVES To analyze factors determining the time between injury and study drug administration (SDA) in a randomized controlled trial (RCT) of acute severe traumatic brain injury (TBI) and to discuss the ethical implications. METHODS Time frames prior to SDA, differentiated per country, were analyzed in a recently conducted RCT in severe TBI. Per protocol, the time window for SDA was 6 h aft...

Structural analysis is concerned with the decomposition of traffic matrix into basis vectors, which corresponds to temporal patterns. In general, the effectiveness of basis vectors is determined by the extent to which it approximates the current week as well as subsequent consecutive week traffic matrix, i.e., the basis vectors should be temporally stable. Principal component analysis (PCA) is ...

The health benefits of long-chain (n-3) PUFA have been widely reported in the literature. Despite the potential benefits, consumption of these fatty acids continues to fall below recommendations from various health and regulatory agencies. Incorporation of long-chain PUFA in foods represents a considerable challenge due to the increased risk of lipid oxidation resulting in the development of of...

The link between specific dynamic action (SDA) and protein deposition was investigated in copepodites stage V of two calanoid copepod species, the neritic Acartia tonsa and the oceanic Calanus finmarchicus. This was done by measuring respiration before, during, and after a specific feeding period and measuring the incorporation of carbon into proteins. These were also measured on individuals in...

Strand displacement amplification (SDA) is an isothermal, in vitro method of amplifying a DNA sequence for diagnostic purposes. We have combined SDA with fluorescence polarization detection in a closed, homogeneous format. A fluorescently labeled oligodeoxynucleotide detector probe hybridizes to the amplification product that increases in concentration during SDA. The single- to double-stranded...

The Bacillus subtilis histidine kinase KinA controls activation of the transcription factor governing sporulation, Spo0A. The decision to sporulate involves KinA phosphorylating itself on a conserved histidine residue, after which the phosphate moiety is relayed via two other proteins to Spo0A. The DNA-damage checkpoint inhibitor Sda halts this pathway by binding KinA and blocking the autokinas...

The "social brain" of humans reflects widespread neural resources dedicated to understanding the conversational language, emotionality, states of mind, and intentions of other persons. A social deafferentation (SDA) hypothesis for induction of active schizophrenia is proposed. Analogous to hallucinations produced by sensory deafferentation, such as phantom limb, the SDA hypothesis assumes that ...
