Ready Mixed Concrete01:26

Ready Mixed Concrete

378
Ready-mixed concrete, also known as pre-mixed concrete, is prepared in a centralized plant and then transported in trucks to construction sites where it is ready for placement. This type of concrete is categorized into central-mixed, truck-mixed (or transit-mixed), and shrink-mixed. Central-mixed concrete is entirely prepared at a plant and moved to the site in agitator trucks that rotate at a speed of 2 to 6 rpm. Truck-mixed concrete, on the other hand, has the ingredients batched at the plant...

Global Climate Change01:50

Global Climate Change

29.1K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Rates of Change01:20

Rates of Change

143
The rate of change is a central concept in mathematics that quantifies how one variable varies in response to another. It serves as a foundational tool in modeling dynamic systems across disciplines such as physics, biology, economics, and engineering. Understanding both average and instantaneous rates of change enables the analysis of behavior in functions that describe real-world phenomena.Average Rate of ChangeFor a function f(x) defined over an interval [x1,x2], the average rate of change...

Work Done During Volume Change

5.3K
In mechanics, work is done on an object when the force acting on it displaces the object. In thermodynamics, work done on a system can be estimated when the system's volume changes during any thermodynamic process.
Consider a gas confined to a cylinder fitted with a movable piston at one end. If the gas expands from volume V1 to volume V2, it exerts a force on the piston, such that the piston moves by a distance dr.
The work done by the gas on the piston can be expressed as

Net Change Theorem01:22

Net Change Theorem

80
The Net Change Theorem is a fundamental principle in calculus that establishes a direct relationship between a function’s rate of change and its accumulated change over an interval. Mathematically, it states that the definite integral of a function's derivative over a given interval [a,b] yields the net change in the original function:This theorem has significant applications in various real-world scenarios, including physics, economics, and engineering. A particularly useful application...

Le Chatelier's Principle: Changing Temperature02:19

Le Chatelier's Principle: Changing Temperature

35.7K
Consistent with the law of mass action, an equilibrium stressed by a change in concentration will shift to re-establish equilibrium without any change in the value of the equilibrium constant, K. When an equilibrium shifts in response to a temperature change, however, it is re-established with a different relative composition that exhibits a different value for the equilibrium constant.
To understand this phenomenon, consider the elementary reaction:

    Summary

    This new psychopharmacology approach classifies drugs by their brain neurobiology and mechanism of action. It helps clinicians target specific patient symptoms by understanding how medications affect brain cells and neurotransmitters.

    Area of Science:

    • Neuroscience
    • Psychopharmacology
    • Clinical Psychiatry

    Background:

    • Current psychotropic drug classification lacks a neurobiological basis.
    • Clinicians need a framework to link medication action to patient symptoms.

    Purpose of the Study:

    • Introduce a novel classification system for psychotropic medications.
    • Align medication selection with neurobiological mechanisms of action.

    Main Methods:

    • Classifying psychotropic drugs based on their specific neurobiological targets in the brain.
    • Focusing on the interaction between drugs, brain cells, and neurotransmitters.

    Main Results:

    • A proposed framework for understanding psychotropic drug action.

  • Emphasis on correcting underlying neurobiological dysfunctions related to patient symptoms.

    • Conclusions:

    • This neurobiological classification aids clinicians in selecting appropriate psychotropic medications.
    • Understanding mechanism of action enhances treatment efficacy for psychiatric conditions.
