Since spermatozoa lack the machinery to repair DNA damage, to improve the likelihood of establishing a healthy pregnancy, it is preferable to process ejaculates of stallions with a high sperm DNA fragmentation index (DFI) before artificial insemination or intracytoplasmic sperm injection.

Effectively enhancing recovery of fine spodumene via

Feb 18, · Abstract The effects of shear strength on aggregation flotation processes for fine spodumene (particle size less than 19 μm) were investigated in this study. Sodium oleate was used as a surfactant and collector. The shear strength was controlled by varying the agitation speed of a selfmade stirring apparatus. The aggregation process was studied by measuring the continuous

Chapter 2 Habitat Fragmentation

The cumulative impact of habitat fragmentation results from the combined incremental effects of habitat loss, reduced patch size, increased edge, and patch isolation. The impacts are cumulative across scales and over time affect populations of organisms as well as individuals. These impacts are not related linearly to the extent of original habitat.

Inertial settling of a sphere through an interface. Part 1

The influence of several of these parameters on four specific features observed in the course of the experiments, namely the pinchoff position, the floating/sinking transition, the volume of the attached drops and the average size of the droplets formed during the fragmentation process, is examined in

The effect of particle size distribution on froth

Aug 31, · While the effect of particle size on froth stability and flotation performance has been the focus of much research, the literature is contradictory on whether fine particles stabilise or destabilise flotation froths from a physicsbased perspective (i.e. negating liberation and surface chemistry effects).

Flotation The Past, Present and Future of Mineral

To me, that is the solution to advanced process control in flotation, he said. I struggle to imagine somebody developing a model, being willing to spend the amount of money that it would take to collect all the data on factors that are likely to affect a flotation process. The alternative is that we learn (the machine learns).

The Effect of Sulfurization Process on Flotation of Copper

In the next step, flotation process was conducted to test the effect of pulp density. The studies were carried out at pH 11.0 and the weight of sample varied at 200 g, 250 g, 300 g and 350 g. Sulfurization conditions for the third sulfurized sample were utilized and


The flotation process has always been considered one of the most effective techniques for particle and fats separation (Ramirez et al., 1999). This process of flotation represents the water treatment process based on the adsorption or attachment of materials on the surface of gas bubble passing through a solution or suspension.
