RESEARCH ON SEED SEPARATION PROCESS ON A GRAVITY-CASCADE SEPARATOR

INMATEH Agricultural Engineering, 2020
Different designs of separators are used for separating seeds. The principle of separator operation is based on various physical, mechanical and aerodynamic properties of seeds. Gravitational separators are promising because energy is not spent on separation process in this type of separators.

Separable Hilbert space in loop quantum gravity [PDF]

Journal of Mathematical Physics, 2004
We study the separability of the state space of loop quantum gravity. In the standard construction, the kinematical Hilbert space of the diffeomorphism-invariant states is nonseparable. This is a consequence of the fact that the knot space of the equivalence classes of graphs under diffeomorphisms is noncountable.

Gravity Separation Tests of a Complex Rutile Ore

Minerals
The complex rutile ore containing TiO2 and ZrO2 exhibited a high economical value. To effectively recover TiO2 and ZrO2 from the raw sample, a complete gravity separation process including a spiral chute and a shaking table was proposed.

Validation of a Probabilistic Mathematical Model for Soybean Seed Separation in a Gravity Column

Сельскохозяйственные машины и технологии
In mathematical models of the separation process in a gravity column, the coefficient of bar vibration is frequently disregarded as seeds and impurities move along the curved surface of the gravity column, which, in turn, affects the quality of ...

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

FEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Versatile vector tools for efficient protein screening across multiple expression systems

FEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for
