Fixed Action Patterns01:06

Fixed Action Patterns

17.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Non-ohmic Devices

1.5K
In most substances, the current flow is proportional to the voltage applied to it. A simple relationship between the values of current, voltage, and resistance is known as Ohm's law. Nonohmic devices do not exhibit a linear relationship between voltage and current. One such device is the semiconducting circuit element known as a diode. A diode is a circuit device that allows current flow in only one direction.
Consider a simple circuit consisting of a battery, a diode, and a resistor. A...

Mnemonic Devices01:23

Mnemonic Devices

432
Mnemonic devices are cognitive tools that facilitate memory retention by linking new information to familiar patterns or organizational strategies. These techniques are beneficial for remembering complex or lengthy sets of information by simplifying and structuring them in easily retrievable ways.
Acronyms
Acronyms are created by using the initial letters of a series of words to form a new word or phrase. This approach condenses complex information into a single, memorable entity. For example,...

Oxygen Requirements and Growth Patterns01:29

Oxygen Requirements and Growth Patterns

1.4K
Microorganisms exhibit diverse oxygen requirements and growth patterns driven by their metabolic strategies and environmental adaptations. Oxygen, while essential for many organisms, can also be toxic under certain conditions, shaping how microorganisms grow and survive.Oxygen Requirements of MicroorganismsMicroorganisms are classified based on their ability to use or tolerate oxygen:● Obligate aerobes like Mycobacterium tuberculosis need oxygen for energy production, as it serves as the...

Burn Injuries01:22

Burn Injuries

4.4K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Summary
This summary is machine-generated.

Seated pedestrians using assisted mobility devices (AMDs) are more likely to have pre-existing health conditions and a higher risk of thoracic injuries like pulmonary contusions when struck by a car.

Area of Science:

  • Trauma research
  • Public health
  • Gerontology

Background:

  • Aging populations increasingly use assisted mobility devices (AMDs) for independence.
  • Pedestrians using AMDs face risks in automobile versus pedestrian (AVP) crashes.
  • This study compares injury patterns and comorbidities in seated versus standing pedestrians involved in AVP crashes.

Purpose of the Study:

  • To compare the injury patterns of seated pedestrians in AMDs versus standing pedestrians struck by automobiles.
  • To analyze comorbidities and outcomes in these two pedestrian groups.

Main Methods:

  • Data from the Arizona State Trauma Registry (2010-2015) for AVP crashes.
  • Matched cohort study comparing seated (n=70) and standing (n=140) pedestrians by age and gender.
  • Analysis of comorbidities, injury patterns, Injury Severity Score (ISS), hospital length of stay (LOS), and mortality.

Main Results:

  • Seated pedestrians had higher rates of comorbidities (89% vs. 66%) and functional dependence (21% vs. 1%).
  • No significant differences in overall injury patterns by body region were observed.
  • Seated pedestrians showed a trend towards more pulmonary contusions (14% vs. 4%).

Conclusions:

  • Injury patterns in seated pedestrians differ slightly from standing pedestrians after AVP crashes.
  • Seated pedestrians are more prone to comorbidities, potentially complicating medical care.
  • Findings emphasize the need for tailored care and injury prevention for vulnerable pedestrian populations.
