Elements and Compounds

Elements and Compounds

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...

Sustainable Development

Sustainable Development

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Periodic Classification of the Elements

Periodic Classification of the Elements

The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

In Vitro Drug Release Testing: Overview, Development and Validation

In Vitro Drug Release Testing: Overview, Development and Validation

In vitro dissolution and drug release tests assess how quickly and how much of a drug is released from its dosage form into an aqueous medium under standardized laboratory conditions. These tests are essential tools in pharmaceutical development and quality assurance, offering insight into the drug's performance before clinical use.During formulation development, dissolution testing identifies incomplete or inconsistent drug release issues. It also supports decisions on selecting the optimal...

Survey Safety

Survey Safety

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Reliability and Validity

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Background:

Head injuries in vehicle crashes pose significant risks to pedestrians.
Finite element (FE) simulations are crucial for understanding pedestrian head injury mechanisms.
Current FE human body models are computationally expensive, limiting broad impact scenario studies.

Purpose of the Study:

To develop and validate a computationally efficient FE pedestrian model.
To facilitate future research on pedestrian head safety.
To overcome limitations of existing models in terms of computing time.

Main Methods:

Development of a FE pedestrian model with 432,694 elements.
Validation of the model at segment and full body levels using cadaver test data.
Analysis of pedestrian responses under lateral impact loading and vehicle-to-pedestrian impact configurations.

Main Results:

The FE pedestrian model demonstrated responses within cadaver test corridors for knee, pelvis, thorax, and shoulder under lateral impact.
Upper body (head, T1, T8) trajectories showed good agreement with cadaver data in vehicle-to-pedestrian impacts.
The model's computational efficiency was established for broader application.

Conclusions:

The developed FE pedestrian model is a validated and computationally efficient tool.
This model can significantly contribute to pedestrian head safety studies.
It offers a valuable resource for simulating various impact scenarios in vehicle-pedestrian crashes.
