Work is done when energy is transferred from one object to another. In other words, work is when a force acts on something that undergoes a displacement from one position to another. Forces can vary as a function of position, and displacements can be along various paths between two points. The increment of work (dW) done by a force acting through an infinitesimal displacement can be defined as the dot product of force () and displacement () vectors.
The dot product can be expressed in...

Work is a fundamental concept of mechanical engineering and has many applications. Understanding how work is calculated and the different types of work can help us better understand physical processes and provide insights into complex problems.
Work is defined as the result of a force acting on an object, causing it to move along the line of action of force. It is also defined as the process of transferring energy through the application of force on an object, resulting in its displacement.

First Pass Effect

7.4K
Presystemic elimination, or the first-pass effect, is the metabolism of drugs that reduces their effective concentration at the site of action. Apart from the first-pass effect, the systemic bioavailability of the drug is also reduced by other factors, including incomplete absorption or chemical degradation of drugs.
Depending on the route of administration, drugs can be metabolized in the liver, intestine, lungs, and vasculature. Orally administered drugs are first absorbed through the...

First Impression

First impressions play a crucial role in social perception, shaping how individuals assess others in professional, academic, and interpersonal contexts. Psychological research highlights the significance of cognitive biases, such as the primacy and recency effects, which influence how people interpret and recall information.The Primacy Effect and Cognitive AnchoringThe primacy effect describes the tendency for initial information to impact judgment disproportionately. When individuals encounter...

Virtual Work

The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

Work Done by Many Forces

The total work done on an object acted upon by multiple forces can be computed using two methods that give the same result. In one method, the work done by each force is first calculated. Then, those values are summed algebraically to calculate the total work done by all the forces. In the second method, the net force is first calculated by a vector sum of all the forces. Then, the work done by this force is obtained.
Since forces perpendicular to the displacement do no work, they do not...

Area of Science:

  • Environmental studies
  • Philosophy
  • Psychology
  • Decolonial studies

Background:

  • The current climate emergency has deep roots in historical and ongoing societal structures.
  • Academic critiques in the 1990s, following the Columbian quincentenary, questioned environmental and ontological perspectives.
  • The emergence of new materialisms and indigenous ontologies signifies a shift in understanding.

Purpose of the Study:

  • To present diverse understandings of the climate emergency's origins.
  • To explore alternative transitional pathways and the role of psychology.
  • To analyze the impact of coloniality on education and worldviews.

Main Methods:

  • Review of environmental and ontological critiques from the 1990s.
  • Analysis of new materialisms and indigenous relational ontologies ('ontological turn,' 'decolonial turn').
  • Examination of coloniality's effects on education and exploration of alternative visions.

Main Results:

  • Identifies deep-rooted causes of the climate crisis in historical and academic analyses.
  • Highlights the significance of decolonial and indigenous perspectives in addressing the crisis.
  • Suggests psychology's potential role in fostering necessary transitions and alternative world visions.

Conclusions:

  • The climate emergency requires understanding its historical and ontological underpinnings.
  • Decolonial and indigenous approaches offer crucial insights for alternative futures.
  • Psychology can contribute to discourse and action for a sustainable transition.
