Optimal Arousal Theory01:23

Optimal Arousal Theory

858
The optimal arousal theory suggests that performance is maximized when an individual experiences a moderate level of arousal. This theory is closely tied to the Yerkes-Dodson law, which illustrates an inverted U-shaped relationship between arousal and performance. The law, formulated by psychologists Robert Yerkes and John Dodson, implies an ideal arousal level for optimal performance, and deviations from this level can lead to declines in effectiveness.

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Social Exchange Theory

40.8K
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Formulation and Manufacturing Process: Physical Attributes of Generic Tablets and Capsules

336
Bioequivalence in generic drugs, such as tablets and capsules, refers to their pharmaceutical equivalence to the brand-name counterparts. However, for therapeutic equivalence, manufacturers must also consider physical attributes like size, shape, and weight (FDA Guidance for Industry, December 2003). Discrepancies in these aspects could impact patient compliance and cause medication errors. For instance, swallowing difficulties, often experienced with larger tablets or capsules, can lead to...

Band Theory02:35

Band Theory

17.2K
When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.
Conductor, Semiconductor,...

Area of Science:

  • Pharmaceutical Technology
  • Materials Science
  • Data Mining

Background:

  • Pharmaceutical pellets are critical spherical dosage forms produced via extrusion/spheronization.
  • Pellet quality, including shape and active pharmaceutical ingredient (API) content, is influenced by composition and manufacturing parameters.
  • Optimizing pellet production requires understanding the impact of various technological process parameters.

Purpose of the Study:

  • To apply a knowledge discovery method, the dominance-based rough set approach (DRSA), to identify critical process parameters in pharmaceutical pellet manufacturing.
  • To establish decision rules linking process parameters to pellet quality attributes.
  • To provide insights for optimizing the extrusion/spheronization process for enhanced pellet quality.

Main Methods:

  • An information system was constructed using condition attributes (API amount, excipient type/amount, screw speed, rotation speed, spheronization time/temperature) and a decision attribute (pellet quality via aspect ratio).
  • The dominance-based rough set approach (DRSA) was employed to analyze the information system and derive decision rules.
  • This data-driven approach aimed to uncover significant relationships between process variables and pellet quality outcomes.

Main Results:

  • The DRSA analysis successfully induced decision rules that highlight significant process parameters affecting pharmaceutical pellet quality.
  • Key technological parameters influencing pellet shape and overall quality were identified through rule induction.
  • The study demonstrated the effectiveness of DRSA in evaluating critical factors in the extrusion/spheronization process.

Conclusions:

  • The derived decision rules offer valuable information for optimizing pharmaceutical pellet manufacturing processes.
  • Understanding and controlling identified critical parameters can lead to improved quality and consistency of manufactured pellets.
  • This research provides a data-driven framework for enhancing drug delivery systems through optimized pellet production.
