Fineness of Cement01:15

Fineness of Cement

539
The fineness of cement directly influences the rate of hydration, as the hydration begins at the surface of the cement particles. In addition to hydration, the fineness of cement is vital for various properties of concrete including workability, gypsum requirement, and long-term behavior. The fineness of cement is represented in terms of the specific surface of cement which is typically measured in square meters per kilogram, with several methods available for this determination.

Fineness Modulus01:19

Fineness Modulus

1.5K
The fineness modulus (FM) of aggregate is a numerical index that measures the coarseness or fineness of the particles. It is calculated by adding the cumulative percentages of aggregate retained on each of a specified series of sieves and dividing the sum by 100.
Consider performing sieve analysis on sand through a set of ASTM sieves. The weight of aggregate retained in each sieve and pan placed at the bottom is recorded, as given in Column B of Table 1.
To determine the fineness modulus of...

Motor Units00:46

Motor Units

62.0K
A motor unit consists of two main components: a single efferent motor neuron (i.e., a neuron that carries impulses away from the central nervous system) and all of the muscle fibers it innervates. The motor neuron may innervate multiple muscle fibers, which are single cells, but only one motor neuron innervates a single muscle fiber.

Motor Units01:13

Motor Units

8.3K
The motor unit is a fundamental component of the neuromuscular system and plays a crucial role in coordinating muscle contractions. It consists of a somatic motor neuron, which connects and controls multiple skeletal muscle fibers, forming a single functional segment. The axon of the motor neuron branches out and establishes synaptic connections known as neuromuscular junctions with individual muscle fibers within the motor unit.
Motor units come in different sizes, with smaller units...

Motor Unit Stimulation01:20

Motor Unit Stimulation

3.9K
When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

Hierarchy of Motor Control01:18

Hierarchy of Motor Control

6.3K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Area of Science:

  • Biomedical Engineering
  • Rehabilitation Science
  • Human-Computer Interaction

Background:

  • Neuromotor rehabilitation requires patient feedback, traditionally subjective and therapist-dependent.
  • Vibrotactile biofeedback shows promise in enhancing rehabilitation interaction and physiological processes.

Purpose of the Study:

  • To design and evaluate an interactive system for upper limb neuromotor rehabilitation.
  • To provide objective, multimodal feedback to patients during rehabilitation exercises.

Main Methods:

  • An interactive system using active markers and image processing for upper limb rehabilitation was developed.
  • The system incorporated drawing activities in augmented and virtual reality environments.
  • Multimodal feedback (vibrotactile, visual, sound) and force measurement were employed for user correction.

Main Results:

  • The system assists patients with shoulder, elbow, or wrist injuries.
  • Eleven participants engaged in fine motor skill strengthening activities.
  • A 10% average improvement in patients' fine motor skills was observed, indicated by reduced error rates.

Conclusions:

  • The developed system offers objective feedback to aid patients in neuromotor rehabilitation.
  • The system has potential applications for nursing assistants in patient care.
  • The findings support the efficacy of audio-vibrotactile feedback in improving fine motor skills.
