To establish a quantitative sampling method using mid-water trawls for estimating the stock abundance of Pacific saury (Cololabis saira), we carried out experimental fishing surveys using two types of mid-water trawl (SM-trawl: 4 panels, trawler 397 GRT and KM-trawl: 6 panels, trawler 2630 GRT).
In the current study, helicopter airborne surveys using two sources were conducted over the northern and eastern parts of the Ontake Volcano area with a flight speed of 50 100 km/h, as shown in Fig. 3.
Therefore, in two completely different genetic surveys, using two distantly related species, an activating mutation in the same conserved tyrosine residue was isolated.
Under the auspices of the Ministry of Education, surveys, using two methods of administration, paper-and-pencil and online, were administered to youth, ages 12 to 18 years (n = 272) who were living at a boarding school in northern Israel.
Both surveys used three cuff sizes.
The LBP prevalence estimates were therefore calculated at each survey using three different methods.
Today, surveys use seven categories and sometimes even more.
We designed an experimental internet survey using nine versions of a questionnaire with each version featuring a unique combination of original photographs, additional text and digitally edited photographs.
STUDY DESIGN: North Carolina Pediatrics Society members completed a self-administered, quasi-experimental mail survey, using two different case vignette versions.
In 1968, Norton Sound of Alaska was surveyed using two National Oceanic and Atmospheric Administration (NOAA) vessels during the Surveyor NORTSD68 cruise and Oceanographer OPR483 cruise (Figure 4).
