The Quality of Colostrum and Its Effects on Calves Growth Characteristics in Holstein Cattle
Journal of Agricultural Sciences, 2007 This study was carried out to determine colostrum quality in Holstein Cows. Colostrum quality has been estimated by using a colostrometer. The colostrometer works by measuring the specific gravity of colostrum and then takein advantage of the linear ...

Separation of Copper from Telephone Cables by Gravity Concentration
Inżynieria Mineralna, 2018 Waste electric and electronic equipment (WEEE) is the fastest growing waste stream compared to other types of waste and thus there is an increasing need for its efficient management. Disposal at landfills is not desired by the fact that this type of waste contains a number of useful materials that can be used again, as well as dangerous substances for ...

Advanced Materials, EarlyView.Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.
