Effect of seminal plasma and egg yolk concentration on freezability of goat semen
The objective of this study was to evaluate the effects of egg yolk and seminal plasma on the viability of cryopreserved goat semen. To this end, four fertile Saanen bucks, aged between 10 months and 1 year, and weighing 18 to 25 kg, were used. Semen was

Evaluation of the Temperature and Time in Centrifugation-Assisted Freeze Concentration
Centrifugation is a technique applied to assist in the freeze concentration of fruit juices and solutions. The aim of this work was to study the influence of the time–temperature parameters on the centrifugation process as a technique applied to assist ...

Solid-liquid separation techniques for efficient recovery of P2O5 from phosphoric sludge [PDF]
Phosphoric acid sludge is one of the prominent problems in the phosphate industry. Its production co-occurs with large losses of P2O5 that affect the process performance. Management and valorization of this waste is a key issue.

Adiabatic field-free alignment of asymmetric top molecules with an optical centrifuge [PDF]
We use an optical centrifuge to align asymmetric top $\mathrm{SO_2}$ molecules by adiabatically spinning their most polarizable O-O axis. The effective centrifugal potential in the rotating frame confines sulfur atoms to the plane of the laser-induced rotation, leading to the planar molecular alignment which persists after the molecules are released ...

Artificial gravity through short-arm centrifugation has potential as a multi-system countermeasure for deconditioning and cranial fluid shifts that may underlie ocular issues in microgravity. However, the optimal short-arm centrifugation protocol that is

Context: To compare optical density (OD) and fibrinogen content of leukocyte-rich and platelet-rich fibrin (L-PRF) generated by standard protocol (2700 rotations per minute [RPM] for 12 min) versus relative centrifugal force (RCF)-adjusted protocol ...
