Sampling Plans01:23

Sampling Plans

994
Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Planning Nursing Care I

6.0K
The planning phase of the nursing process helps nurses set priorities, outline patient-centered goals and expected outcomes, and tailor nursing interventions to align with the aligned care plan. Through the planning phase, the nurse applies critical thinking skills to align and develop interventions according to the patient's needs. It provides continuity of care allowing patients to receive the maximum benefit from treatment. It serves as a pilot plan for allocating individual staff to a...

Planning Nursing Care II

A nursing care plan can present in two forms: informal and formal. Informal is a care plan for the individual use of the nurse and goals they wish to accomplish during their shift. Informal care plans are not included in the patient chart. A formal nursing care plan is a written or computerized guide that organizes patient care. It is further subdivided into two: standardized and individualized care plans. Standardized care plans are pre-populated care plans for specific patient populations,...

Field Effect Transistor01:29

Field Effect Transistor

1.2K
Field-effect transistors (FETs) are integral to electronic circuits and distinguished by their three-terminal setup: the gate, drain, and source. These transistors operate as unipolar devices, which utilize either electrons or holes as charge carriers, in contrast to bipolar transistors, which use both types of carriers. The primary function of the FET is to modulate the flow of these carriers from the source to the drain through a channel. The voltage difference between the gate and source...

Electric Field01:16

Electric Field

12.9K
Consider two point charges, each exerting Coulomb force on the other. It is possible to describe the Coulomb interaction via an intermediate step by defining a new physical quantity called the electric field.
In the new picture, imagine that the first charge sets up an electric field independent of all other charges in the universe. When another charge comes in its vicinity, the second charge experiences an electric force depending on the electric field at that point. The source charge does not...

Area of Science:

  • Agricultural Entomology
  • Pest Management
  • Quantitative Ecology

Background:

  • Brown stink bug (Euschistus servus) is a significant pest impacting corn (Zea mays) production in the southeastern US.
  • Effective integrated pest management (IPM) strategies necessitate reliable population monitoring tools.
  • Understanding the spatial distribution of E. servus is key to developing efficient sampling plans.

Purpose of the Study:

  • To develop a practical and reliable sampling plan for monitoring Euschistus servus populations in commercial corn fields.
  • To determine the optimal sample size for estimating E. servus density at different corn growth stages.
  • To compare the cost-reliability of whole plant versus partial plant sampling methods.

Main Methods:

  • Field sampling of E. servus adults and nymphs in North Carolina corn fields (n=14) over two years (2016-2017).
  • Analysis of spatial distribution using variance-to-mean ratio and Taylor's power law (b).
  • Calculation of optimum sample sizes based on Taylor's power law constants and economic thresholds for different corn growth stages (V4-V6, R1-R4).

Main Results:

  • Euschistus servus exhibited a predominantly aggregated spatial distribution in corn.
  • Optimal sample sizes varied by corn growth stage and sampling method, with specific numbers calculated for vegetative and reproductive stages.
  • Partial plant sampling was found to be equally or more cost-reliable than whole plant sampling for E. servus adults across all tested corn growth stages.

Conclusions:

  • The aggregated distribution of E. servus necessitates careful consideration in sampling plan design.
  • Partial plant sampling offers a cost-effective alternative to whole plant sampling for managing brown stink bug populations in corn.
  • Implementing these findings can enhance the efficiency and effectiveness of IPM programs for E. servus in corn.
