Sampling Design Sample Clauses

Sampling Design. An appropriate and defensible sampling design should be used as the basis for data collection for use in compliance decisions. The choice of a sampling design depends on several factors including but not limited to, the decision to be made with the data, frequency of dredging, historical or known location of shoaling, historical or known volumes of materials dredged, and cost of sampling and analysis. Chapter 8 of both the Green Book and ITM, should be used for detailed guidance for developing the sampling strategy, however, the guidance provided in the ITM is more technically advanced and should be used as reference for preparing a sampling strategy. Plumb (1981) provides additional guidance on sample design.

Sampling Design. The sample design applied was unchanged from what was proposed in the feasibility study (D1.1) and delivered in D1.2 as a as a georeferenced vector file. The approach is summarised as follows. The selection of sample units was based on a stratified systematic and random sampling selection (two stage approach). The first stage was implemented by applying a 20 x 20 km grid over the overall area of the AOI. In a second stage, multiple sample units were randomly selected in sequence for each grid cell based on the 500 x 500 m sub-grid as illustrated in Figure 3; resulting with 338 segments selected. 1 ▇▇▇▇▇://▇▇▇▇▇▇▇▇▇.▇▇▇▇▇▇▇▇▇▇.▇▇/web/cscda/dataset-details?articleId=394198 The spatial distribution of the sample units over the crop and non-crop strata are shown in Figure 4 However, a visual assessment of some of the selected segments was made during the feasibility study and showed that some crops were also sometimes present in the other areas stratum. Therefore, this assessment was conducted based on available imagery from Google Earth / Bing Maps over all segments to identify, from the overall samples, the segments without any crops present. This information was used to determine the number and location of the segment to be surveyed as an input to the contract for Upande Ltd. In total out of the overall sample of 338 segments, 259 segments were identified to contain field parcels and therefore were to be surveyed. 5.1 Segment survey protocol

Sampling Design. The FSA will provide data on the consumption of fresh, chilled salmon (kg) broken down by retailer, government office region, and month of the year (this is based on the Defra’s latest Family Food dataset as derived from the 2019/20 Expenditure and Food Survey). We can also provide population data for local authorities, to aid sampling within regions. This information should be used to produce a sampling plan that is representative of UK market share for these factors. Applicants should sample according to the marginal totals of market share data provided across retailers and should indicate how well represented different regions of the UK will be in their sampling. We encourage applicants to finalise sampling plans in discussion with FSA statisticians and microbiologists. N.B. Care should be taken to avoid sampling multiple raw salmon from the same batch. This survey and sampling design will be subject to expert peer-review as part of the FS900350 tender evaluation process. On award of the contract, the successful applicant will be required to submit a more detailed design reflecting the requirements as set out in this specification document. In addition to the survey design, the contractors for Lot 1 will be expected to conduct the sampling and transportation of collected samples to the testing facility, ensuring that there is a robust system for sample identification and data recording, and that samples are handled appropriately, including use of methods to avoid cross-contamination and ensuring adequate temperature controls during transit, making sure all samples receive identical sampling and transportation processes. Close liaison with the testing laboratory is essential to ensure correct sample handling and agree delivery times, as well as for the transfer of sample information. Samples must have sufficient time left on the use by date to ensure that they are still in date when tested. Once samples have been purchased, the manager of the retail outlet should be handed a letter that FSA will provide, explaining that a sample has been taken and what it will be used for. The applicant should create an Excel spreadsheet database, which is password protected, of the samples collected with the following details being recorded for each sample at the point of sampling: • A unique sample number (to be determined by the sampler) • Date and time of purchase • Retail outlet name and address • Brand name (if any) • Skin or skinless • Product full text descriptio...

Sampling Design. A Generalized Random-Tessellation Sampling (GRTS) survey design was recommended by ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇ (2009) for monitoring habitat status and trend in the Columbia River Basin. The GRTS design was initially developed under the EPA’s Environmental Monitoring and Assessment Program and is a probabilistic sampling design that has been shown to be advantageous for generating habitat condition parameters with known statistical characteristics. The CHaMP monitoring design follows a GRTS design with a 3 year rotating 1-to-1 split panel structure to distribute sampling effort in space and time, and has management tools for sampling design. Implementing a GRTS survey design correctly is critical to producing a final dataset with known statistical characteristics requiring the implementation of strict procedures during the site evaluation and selection process. A GRTS Site Selection Protocol and Tool will be provided to each collaborator to support field crews with efficiently completing the process while strictly enforcing design requirements.

Sampling Design. The following section provides an overview of the sampling effort for game that will be conducted. Detailed information on sampling procedures and methods are presented in Section B2. Two game species (deer and elk), one animal for each, will be collected from area(s) within the OU3 site. If an elk cannot be collected within a two-week baiting period, then two deer may be collected. Muscle (flank and backstrap) tissue samples will be collected from each game animal and analyzed for LA. Measured LA concentrations in muscle tissue will be used to determine if human exposures to LA from ingestion of game have the potential to cause unacceptable health risks. Five other types of tissue will be also collected from the game animals, including liver, kidney, lung, diaphragm, and heart, to provide additional information on tissue burdens in game animals. Fish (trout) were collected from the Mill Pond as part of the implementation of the OU3 Phase V Part B SAP/QAPP (EPA 2012a). These fish are currently frozen in archive at the CDM ▇▇▇▇▇ field office in Libby. These fish will be sent to the analytical laboratory, filleted, and the fillet samples will be analyzed for LA. Measured LA concentrations in fillet tissue will be used to determine if human exposures to LA from ingestion of fish have the potential to cause unacceptable health risks.

Sampling Design. To begin monitoring effects of treatments, one 96 ft by 96 ft (0.212 acre) test plot within each field was selected. The two test plots, North and South, were each divided into sixteen, 24 ft by 24 ft (0.013 acre) subplots (see photo) to test four iterations of each of the treatments. In addition to the control, treatments for the North and South test plots were: biochar only, compost only, and a biochar and compost mix (mix). The recommended methods in “A Guide to Conducting Biochar Trials” by the International Biochar Initiative (pages 7-14) were used to design the layout of the subplots, and randomize the assignment of treatments to subplots (Major, 2009). Refer to Appendix 1 for the coordinates of the test plots, and the randomization values used to assign treatments to subplots. Table 2 indicates which treatments were assigned to the North and South subplots.

Sampling Design. The sample type was a purposive sample which were recorded previously and diagnosed according to the current diagnostic criteria for pelvic organs tumor enrolled in (MoH) from three Medical complex centers (AL Shifa, Rantisi specialist of pediatric hospital and EGH) in Gaza strip, numbering 120 patient from the date of the beginning of electronic archiving in MoH (May 2017) to beginning study data (March 2019).

Sampling Design. The following provides an overview of the sampling effort that will be conducted. Detailed information on sampling procedures and methods are presented in Section B2. Sampling will begin with the collection of one tree bark composite sample from the sample location. A total of fifty tree bark composite samples will be collected. Following bark collection, one duff composite sample will be collected near each tree that was sampled for tree bark. A total of fifty duff composite samples will be collected. The requirements for field QC sample collection are discussed in Section B5.1.

Sampling Design. Sampling plans for ▇▇▇▇▇▇▇▇▇▇ sites will consider site conditions as they relate to known or suspected releases of hazardous substances. Plans will be developed according to the specific needs and phase of each ▇▇▇▇▇▇▇▇▇▇ site. Typical plans may focus on establishing a baseline for existing contamination at a site, filling data gaps from previous investigations, or documenting that a remedial action has been completed according to site-specific cleanup goals. Contractors will be responsible for coordinating with the appropriate analytical laboratory for proper sampling containers, forms, and equipment at least two weeks prior to conducting field activities. Any field activities involving sampling will require a site-specific SAP to be submitted by the contractor for DEQ and EPA approval prior to initiating field activities. These plans must include the information listed in Section A6 of this QAPP. Sampling equipment will be assembled based on the type of samples to be collected from the site. All sampling equipment will be checked for proper calibration, assembly, and operation prior to use. Sampling equipment will be transported in a manner that will preserve its cleanliness.
