The Roles of Bacteria and Fungi in Plant Nutrition02:11

The Roles of Bacteria and Fungi in Plant Nutrition

47.4K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Machines

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. One example of a machine is the cutting plier, which is used to cut wires by applying forces to its handles. When equal and opposite forces are exerted on the handles of the cutting plier, they cause the cutting edges to come together and apply equal and opposite reaction forces on the wire, which are greater than the applied forces.

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Organisms exhibit remarkable metabolic diversity, categorized based on how they acquire energy and carbon. These strategies enable survival in various ecological niches and are essential for maintaining energy flow and nutrient cycling within ecosystems.Energy and Carbon SourcesOrganisms are classified as phototrophs or chemotrophs based on energy acquisition. Phototrophs use light as their energy source, while chemotrophs rely on oxidizing chemical compounds. Further differentiation arises...

Area of Science:

  • Public Health
  • Nutrition Education
  • Machine Learning Applications

Background:

  • Participant attrition in nutrition education programs like EFNEP can limit program effectiveness.
  • Identifying at-risk individuals is crucial for targeted interventions and resource allocation.

Purpose of the Study:

  • To develop and evaluate machine learning models for predicting attrition among adult EFNEP participants using preprogram data.
  • To identify key predictors of attrition to inform retention strategies.

Main Methods:

  • Secondary data analysis of 339,335 adult EFNEP participants nationwide (2013-2022).
  • Development and comparison of logistic regression, random forest, and eXtreme Gradient Boosting models.
  • Prediction of attrition based on preprogram food behaviors, dietary intake, demographics, and program characteristics.

Main Results:

  • The eXtreme Gradient Boosting model showed the best predictive performance (F1 score=0.68, recall=70%).
  • Significant predictors of attrition included Cooperative Extension region, EFNEP funding tier, enrollment year, income, age, race, residence, number of children, and preprogram diet/activity levels.

Conclusions:

  • Machine learning effectively identifies patterns associated with attrition in nutrition education programs.
  • These models can guide targeted interventions to enhance participant retention and program impact.
