A retrieval lanyard is a nylon webbing lanyard used to raise and lower workers into confined spaces, such as storage tanks. An activation lanyard is a lanyard used to fire an artillery piece or arm the fuze on a bomb leaving an aircraft. [5] A deactivation lanyard is a dead man's switch, where pulling a lanyard free will disable a dangerous device.
The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
In the 'disengage' style MARDs, a small but simple hook attached to the pilot chute allows for the RSL to include a lanyard that is engaged with the hook. During main canopy jettison, the RSL opens the container, and the included lanyard pulls the hook, which extracts the reserve deployment bag and begins the rest of the reserve deployment.
Biology Today: An Issues Approach is a college-oriented Biology textbook by Eli C. Minkoff and Pamela J. Baker designed to integrate the teaching of biological concepts within the context of current societal issues relating to these topics. [1] It is the original issues-oriented introductory-level general biology textbook. [2]
Entrez is both an indexing and retrieval system having data from various sources for biomedical research. NCBI distributed the first version of Entrez in 1991, composed of nucleotide sequences from PDB and GenBank, protein sequences from SWISS-PROT, translated GenBank, PIR, PRF, PDB, and associated abstracts and citations from PubMed. Entrez is ...
A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of the corkscrew-like flagella of many prokaryotes).
In biology, an identification key, taxonomic key, or frequently just key, is a printed or computer-aided device that aids in the identification of biological organisms. Historically, the most common type of identification key is the dichotomous key , a type of single-access key which offers a fixed sequence of identification steps, each with ...
