Identification was done by a botanist, Dr. Tsabang Nole of the Institute of Medical Research and Medicinal Plants Studies (IMPM), Yaoundé, Cameroon with voucher specimen references as follows: M. indica (TN6225), P. guajava (TN6226), C. papaya (TN6227), C. citratus (TN6228), C. sinensis (TN6229), O. gratissimum (TN6230).
The Haigh diagram shows a good matching between the specimen reference material and the component fatigue data.
In this study, three different fracture toughness testing methodologies are investigated: three-point bending on Chevron notched specimen ("reference" baseline), Palmqvist indentation test, and Hertzian indentation method.
and deposited at Raw Materials Herbarium & Museum, NISCAIR, New Delhi (specimen reference number 1729/29).
Plant identification and voucher specimen referencing were done at the Institute of Medical Research and Medicinal Plants Studies (IMPM) Herbarium, Yaoundé, Cameroon, by a botanist.
The plant was identified at the Scientific Institute of Rabat by Prof. M. Fennane, and the specimen was deposited in the Scientific Institute herbarium under the voucher specimen reference N° RAB78140.
The plant identity was confirmed by Dr. Marlene Cross, Department of Biology, Mercyhurst University, and a reference voucher specimen (Reference number: TREC He- 00818) was deposited in the Herbarium of the Tom Ridge Center, Erie, Pennsylvania [ 23].
The first group included three unreinforced concrete slab specimens (References).

The contact probe, specimen and reference probe are immersed within a chosen electrolyte, which for this study, is aqueous 0.01% NaCl.
Our current efforts to create the holistic, deterministic (a single specimen), and reference atlas have taken more than a decade and this is still work in progress.
