Studies of literature, herbarium specimens, and living plants support the recognition of the three new species: Begonia culasiensis, B. merrilliana, and B. sykakiengii.
Both the specimens and library support the Harvard University course "Plants and Human Affairs" that has been taught to Harvard students for over 100 years.
Bleach-sedimentation has been hypothesised to concentrate acid-fast bacilli in sputum specimens and in support of this hypothesis a recent meta-analysis reported that bleach-sedimentation caused a 9% increase in tuberculosis diagnostic sensitivity compared to conventional smear-microscopy [ 13].
The technique is similar to the pushout test of fiber-reinforced ceramics, except for the specimen shape and support method.
Inconsistencies in design capacity predictions are considered to be due to the fact that the specimen length and support conditions pertaining to the test set-up varied among past experimental studies.
The design of bi-axial experiment is presented, in which the effects of the specimen geometric parameters, the contact between the specimen and the support, and the plastic deformation of substrate are numerically analyzed.
This is because the impact energy depends significantly on many parameters such as strain rate, shape of projectile, material and stiffness of the projectile and the specimen, incident energy, and support boundary conditions.
We thank Ms. Juliet Joly for her technical help with the manuscript preparation, and Drs. Subhashree Madhavan and Wei Lin for their help with the CEL files on the GEO site, Drs. Abbas Shakoori and Konstantin Shilo for assistance with the pathology specimens, and Dr. Kenneth Buetow for support.
