Summary
A new, safe, fast, and inexpensive method for imaging herbarium specimens was developed. This technique allows small herbaria to digitize their collections efficiently, improving access to botanical data.
Area of Science:
- Botany
- Biodiversity Informatics
- Digital Curation
Background:
- Major institutions are digitizing collections, but many smaller herbaria lack resources.
- Less than 1% of Japan's 10 million herbarium specimens are digitized.
- Improved access to digitized specimens is crucial for scientific research.
Purpose of the Study:
- To present a new, accessible imaging method for herbarium specimens.
- To enable local and small herbaria to digitize their collections effectively.
- To meet minimum image quality standards for long-term digital preservation.
Main Methods:
- Development of a custom-made copy stand and LED lighting system.
- Utilized a mirrorless interchangeable lens camera for specimen capture.
- Employed three part-time workers over an eight-month period.
Main Results:
- Successfully imaged 73,180 herbarium specimens.
- Achieved an average imaging rate of 571 specimens per day.
- Produced two RAW and two JPEG files per specimen, meeting quality guidelines.
Conclusions:
- The described method is safe, fast, simple, and cost-effective for digitizing herbarium specimens.
- This approach is suitable for small or local herbaria, enhancing collection accessibility.
- The generated digital files are appropriate for long-term storage and future use.

03:21Genome Size and the Evolution of New Genes
9.1K
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Cell sizes vary widely among and within organisms. Bacterial cells range between 1-10 micrometers (μm)and are considerably smaller than most eukaryotic cells. The smallest bacteria are 0.1 μm in diameter—about a thousand times smaller than eukaryotic cells, which typically range from 10-100 μm.

01:21Brick Sizes

Brick sizing plays a crucial role in construction, influencing both the aesthetics and structural integrity of buildings. Bricks are defined by three dimensions: width, thickness, and length. They are commonly designed to fit modular measurements, typically in multiples of 4 inches or 8 inches in width, to facilitate uniform construction and compatibility with other building materials.
Modular bricks are the most common type and are sized to include the mortar joint, which is essential for...

8.0K
A simple pendulum consists of a small diameter ball suspended from a string, which has negligible mass but is strong enough to not stretch. In our daily life, pendulums have many uses, such as in clocks, on a swing set, and on a sinker on a fishing line.
The period of a simple pendulum depends on two factors: its length and the acceleration due to gravity. The period is completely independent of any other factors, such as mass or maximum displacement. For small displacements, a pendulum is...

01:12Maximum Size of Aggregate
550
The maximum size of aggregate is defined as the aperture of the sieve retaining 15 percent or more of the particles present in the aggregate sample. The aggregate's maximum size impacts the concrete's water requirement, workability, and strength. Larger aggregates reduce the surface area needing cement paste coverage, which can lower water needs, thereby allowing a decrease in the water-to-cement ratio when the desired workability and richness of the mix are to be maintained, which can...
