Trimmed Mean01:10

Trimmed Mean

3.4K
While measuring the mean of a data set, care needs to be taken when associating the mean to its central tendency. The same goes for the arithmetic mean, the geometric mean, or the harmonic mean. This is because the presence of a single outlier data value can significantly affect the mean. That is, the mean is sensitive to fluctuations in the data set.
Although certain measures of central tendency are not sensitive to outliers, there are alternative versions of the mean that get around the...

Sampling Continuous Time Signal

751
In signal processing, a continuous-time signal can be sampled using an impulse-train sampling technique, followed by the zero-order hold method. Impulse-train sampling involves the use of a periodic impulse train, which consists of a series of delta functions spaced at regular intervals determined by the sampling period. When a continuous-time signal is multiplied by this impulse train, it generates impulses with amplitudes corresponding to the signal's values at the sampling points.
In the...

Sampling Methods: Sample Types

3.3K
Sampling materials are classified into three main types: solid, liquid, and gas.
Solid samples include a variety of substances, such as sediments from water bodies, soil, metals, and biological tissues. Two standard methods for extracting sediments from water bodies are grab sampling and piston coring. Grab sampling involves using a device to collect a discrete sediment sample from the bottom of a water body with minimal disturbance. Grab samples do not always represent the entire area due to...

Three-Dimensional Microscopy in Microbiology

842
Three-dimensional imaging techniques are essential in cell biology, allowing researchers to visualize intricate cellular structures with high resolution. Two prominent methods, Differential Interference Contrast Microscopy (DIC) and Confocal Scanning Laser Microscopy (CSLM), provide distinct advantages for imaging live and thick specimens, respectively.Differential Interference Contrast MicroscopyDIC microscopy enhances contrast in transparent, unstained samples by converting phase...

Convenience Sampling Method00:55

Convenience Sampling Method

11.6K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
Convenience sampling is a non-random method of sample selection; this method selects individuals that are easily accessible and may result in biased data. For example, a marketing...

Area of Science:

  • Food Safety
  • Microbiology
  • Agricultural Science

Background:

  • Current pathogen sampling methods for fresh beef may not adequately represent the proportion of beef trimmings in large batches.
  • Effective pathogen detection is crucial for ensuring the safety of fresh beef products.

Purpose of the Study:

  • To compare the efficacy of two novel, nondestructive sampling devices (CSD and MSD) against established industry methods (N60 Excision and N60 Plus) for pathogen detection in beef trim.

  • Analysis of samples for naturally occurring Escherichia coli O157:H7, Salmonella, inoculated surrogates, and indicator organisms.
  • Experiments conducted across multiple plants, days, and lean percentage mixtures.

Main Results:

  • Both CSD and MSD demonstrated similar or better organism recovery compared to N60 Excision and N60 Plus.
  • CSD showed similar prevalence of Salmonella and indicator organisms compared to N60 methods.
  • CSD and MSD detected similar or higher prevalence of E. coli O157:H7 and its surrogates, with comparable indicator organism levels.

Conclusions:

  • The continuous sampling device (CSD) and manual sampling device (MSD) are effective alternatives for sampling beef trim.
  • These novel methods offer comparable or superior pathogen and indicator organism recovery to current industry standards.
  • Implementing CSD or MSD can enhance pathogen sampling and detection programs in fresh beef processing.
