Two Applications of Boolean Valued Analysis [PDF]
Siberian Mathematical Journal, 2019, Vol.60, No.5, 902-910, 2019 The paper contains two main results that are obtained by Boolean valued analysis. The first asserts that a universally complete vector lattice without locally one-dimensional bands can be decomposed into a direct sum of two vector sublattices that are laterally complete and invariant under all band projections and there exists a band preserving linear ...

The effect of duration of preservation on the quality, MDA level, and DNA damage of post-thawed Bali cattle bull sperm [PDF]
Iraqi Journal of Veterinary Sciences, 2019 Frozen semen quality is one of many factors that promote successfully of artificial insemination. Preservation at 5ºC is one of the steps of semen freezing to obtain high fertility sperm after added with the extender.

Determination of a cooling-rate frame for antibiotic-free preservation of boar semen at 5°C
PLoS ONE, 2020 Hypothermic storage of boar semen provides the possibility to omit antibiotics from semen extenders so long as sperm quality is maintained and bacterial growth prevented. The objective of this study was to determine an optimal cooling-rate frame for boar

Kinetic Analysis of Discrete Path Sampling Stationary Point Databases [PDF]
, 2006 Analysing stationary point databases to extract phenomenological rate constants can become time-consuming for systems with large potential energy barriers. In the present contribution we analyse several different approaches to this problem. First, we show how the original rate constant prescription within the discrete path sampling approach can be ...

Recent advances in preservation of boar semen in liquid state: An overview
International Journal of Chemical Studies, 2020 Current century of artificial insemination (AI) of female pigs, knowledge about the preservation of boar semen is still very limited. In pig liquid semen preservation was mainly done at 15-20 ˚C for 5 days. The short-term and long-term extenders are used
