How fertile are earthworm casts? A meta-analysis
Geoderma, 2019It has long been established that earthworms beneficially affect plant growth. This is to a large extent due to the high fertility of their casts. However, it is not clear how fertile casts are compared to bulk soil, and how their fertility varies ...

Accuracy of transferring analog dental casts to a virtual articulator.
The Journal of prosthetic dentistry (Print), 2020STATEMENT OF PROBLEM Complex digital workflows have been developed to create virtual dental patients. Direct and indirect digital methods are available for transferring analog patient information to virtual articulators. The direct method consists solely

Dermatology, 1980
Peripilar hair casts are a pathological occurrence which is probably greater than the few reports seem to suggest. In 2 patients the authors have found fine, whitish nodular accretions of epithelial cells and keratinous debris surrounding the hair shafts of the scalp over a length of 3–7 mm located at various distances from the base of the hair along ...

International Journal of Dermatology, 1988
A case of hair casts in an 8-year-old girl is described. The disorder is rare, the first description dating back to 1897 with a total of only 31 cases reported in the literature since then. The results of research conducted using the optic and electron microscopes (transmission and scanning) are recorded.

Evaluation of the accuracy of digital and 3D-printed casts compared with conventional stone casts.
The Journal of prosthetic dentistry (Print), 2020STATEMENT OF PROBLEM Digital scans present an efficient substitute for traditional dental impressions, although physical casts are still needed for some procedures, leading to the use of 3D printing in fixed prosthodontics. However, studies comparing the
