USING FIBERGLASS TO CONSOLIDATE COMPLEMENTING MATERIALS IN ARCHAEOLOGICAL GLASS “EXPERIMENTAL STUDY” [PDF]

open access: yesShedet, 2020
Due to the breakable nature of glass, archaeological objects made of that material lose some of their parts and need to be completed.A new technology using fiberglass is presented in the consolidation and improvement of the properties of complementing ...

Crossing the Finish Line

open access: yesJournal of Postsecondary Student Success, 2021
Each year, hundreds of thousands of students leave higher education without earning their degree. Helping these students return and complete their degree is an enormous opportunity for higher education to propel social and economic mobility for students

Another proof of Banaschewski's surjection theorem [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2019
We present a new proof of Banaschewski's theorem stating that the completion lift of a uniform surjection is a surjection. The new procedure allows to extend the fact (and, similarly, the related theorem on closed uniform sublocales of complete uniform ...

Completed careers [PDF]

open access: yesIEEE Electromagnetic Compatibility Magazine, 2012
We find that another of our outstanding EMC contributors for many decades has passed on. Dr. Tom Dvorak, as I would like to say, was father of the enormously successful EMC Zurich symposium held in several venues but mostly in Zurich, Switzerland. I recall all the times I attended this symposium, giving papers and workshops and chatting with Tom.

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

open access: yesPopulation Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Influence of Fault Slip on the Stress of Perforated Casing in Shale Gas Horizontal Wells of Baima Block

open access: yesShiyou jixie
Casing deformation seriously restricts the development and utilization of shale gas in Baima block. To clarify the stress variation law of perforated casing under fault slip, study was conducted using a combination of field investigation and numerical ...

Complete mergeability and amodal completion [PDF]

open access: yesActa Psychologica, 1999
When image fragments are taken to correspond to the visible portions of a single occluded object, the object is said to 'amodally complete' behind the occluder. Kellman and Shipley (Kellman, P. J., & Shipley, T. F. (1991). A theory of visual interpolation in objective perception.

Elementary quotient completion [PDF]

open access: yes, 2012
We extend the notion of exact completion on a weakly lex category to elementary doctrines. We show how any such doctrine admits an elementary quotient completion, which freely adds effective quotients and extensional equality. We note that the elementary

UV completion without symmetry restoration

open access: yes, 2013
We show that it is not possible to UV-complete certain low-energy effective theories with spontaneously broken space-time symmetries by embedding them into linear sigma models, that is, by adding "radial" modes and restoring the broken symmetries.

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders

open access: yesPopulation Ecology, EarlyView.
We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...
