Sustainable Development

15.1K
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.

Design Example: Sustainability in Concrete Building

412
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

Communication01:03

Communication

8.7K
Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

65.9K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Aggression01:47

Aggression

30.4K
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Additional Subnuclear Structures02:10

Additional Subnuclear Structures

5.4K
The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals. 
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles,...

Summary

BioPortal hosts numerous biomedical ontologies, but many large ones lack maintenance. Key reasons for discontinued ontology support include funding shortages and resource limitations.

Area of Science:

  • Biomedical Informatics
  • Ontology Engineering

Background:

  • BioPortal is a leading repository for biomedical ontologies, containing 716 diverse ontologies as of June 2018.
  • It provides metadata on ontology size, update frequency, and usage.
  • Observed maintenance gaps in large, effort-intensive ontologies prompted further investigation.

Purpose of the Study:

  • To investigate the reasons behind the lack of sustained maintenance for biomedical ontologies within the BioPortal repository.
  • To identify common factors contributing to the discontinuation of ontology development and support.

Main Methods:

  • Conducted an informal email inquiry with ontology curators.
  • Analyzed factors affecting the long-term maintenance of biomedical ontologies.

Main Results:

  • Lack of funding is a primary reason for discontinued ontology maintenance.
  • Unavailability of human resources significantly impacts ontology support.
  • Ontologies being merged or folded into other projects is another common factor.

Conclusions:

  • Sustained maintenance of biomedical ontologies is challenged by financial and human resource constraints.
  • Strategic decisions, such as ontology integration, also contribute to maintenance cessation.
  • Understanding these factors is crucial for the long-term viability of biomedical knowledge resources.
