Indoors, pollutants in dust and air are often generated from sources such as environmental tobacco smoke, building materials, furniture, cleaning and hygienic products, air fresheners, computers, printers, cooking and other indoor activities, and from people themselves.
For example, EC and OCM are often generated by motor vehicles, whereas sodium ion is associated with aerosolized sea salt (Ito et al. 2004; Schlesinger 2007; Thurston et al. 2011), although these pollutants all have multiple sources.
If we consider that eye, head, and body rotations are often generated simultaneously, multiple efference copy signals must be added together and subsequently discounted from the resultant optic flow to signal heading accurately.
Peptide libraries that include fluorogenic and binding tags are often generated by solid-phase synthesis.
In classical TV algorithm and Curvelet threshold algorithm, the staircase effects and curve-like artifacts are often generated in the restored cartoon part, respectively.
The proteases that activate PARs are often generated and secreted during injury and inflammation, and PARs orchestrate tissue responses to these insults, including hemostasis, inflammation, nociception, and repair mechanisms [ 34].
However, in addition to the desired precision base substitution, other types of mutations such as indel and proximal-site deamination are often generated.
Nanomaterial interactions with biological systems are complex and, accordingly, associated data are often generated at multiple levels of detail.
The recent large-scale studies [ 47, 49] suggested that 63 to 72% of all genome-mapped transcription units in the mouse overlap with antisense cDNA or EST and multiple-sized transcripts are often generated from the SA loci [ 48].
Many districts, however, lack reliable information, and in this case, data on causes of death and burden of disease profiles are often generated from a small number of longitudinal community demographic surveillance sites that collect data on probable cause of death through verbal autopsy (6).
