Although a substantial body of information exists regarding the use of solid minerals as electron sinks for biological processes (e.g., the reduction of ferric iron [ 20]), considerably less is known about how microorganisms recognize, attach to, and extract electrons from solid substrates.
Substantial data exists about the information sources women use for utilising complementary medicines and treatments generally, however little is known about the sources of information used in pregnancy.
Although substantial genomic information existed for bacterial endosymbionts before any such aphid resources, the development of aphid genomics has led to a better understanding of the interaction between bacterial endosymbionts and host species, namely with Buchnera aphidicola [9], [28], [29], [30], [31].
It is clearly observed from this figure that substantial amount of spectral information exists in high frequency region ((>40) Hz) of the averaged magnitude spectra.
Nevertheless substantial information gaps exist as to the exact incidence, prevalence, therapy and particularly to associated therapeutic success.
However, based on the low-pass filtering results it appears that substantial information does exist even when the size of the smoothing window is on the order of a second.
Very few have studied the viability of postcard prenotification even though use of postcards brings about rather substantial cost savings relative to other forms; what information exists comes from studies undertaken in the context of a telephone survey.
Although surgical site infections (SSIs) are known to cause substantial illness and costs during the index hospitalization, little information exists about the impact of infections diagnosed after discharge, which constitute the majority of SSIs.
Whereas serosurveys have been successfully conducted in developing countries with pediatric immunization schedules that follow EPI guidelines, 5, 6 little information exists on how to overcome the substantial logistical challenges that such efforts entail, particularly in rural regions.
Although there is substantial research on mode I fracture behaviour of composites, limited information exists on mode II behaviour.
