Several plants, including nightshade, become more toxic as they wilt and die, posing a danger to horses eating dried hay or plant matter blown into their pastures. [ 3 ] The risk of animals becoming ill during the fall is increased, as many plants slow their growth in preparation for winter, and equines begin to browse on the remaining plants.
Silicone rubber is an elastomer composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations. Silicone rubbers are often one- or two-part polymers, and may contain fillers to improve properties or reduce cost.
The treatment of equine lameness is a complex subject. Lameness in horses has a variety of causes, and treatment must be tailored to the type and degree of injury, as well as the financial capabilities of the owner. Treatment may be applied locally, systemically, or intralesionally, and the strategy for treatment may change as healing progresses.
Bis(trimethylsilyl)amine is synthesized by treatment of trimethylsilyl chloride with ammonia: [3] 2 (CH 3) 3 SiCl + 3 NH 3 → [(CH 3) 3 Si] 2 NH + 2 NH 4 Cl. Ammonium nitrate together with triethylamine can be used instead. [4] This method is also useful for 15 N isotopic enrichment of HMDS.
Krytox fluoroether-based grease pictured alongside a tube of Dow Corning silicone grease (green). Both are often used in laboratories, including in high-vacuum applications, due to their inertness. Both are often used in laboratories, including in high-vacuum applications, due to their inertness.
Polyvinyl siloxane (PVS), also called poly-vinyl siloxane, vinyl polysiloxane (VPS), or vinylpolysiloxane, is an addition-reaction silicone elastomer (an addition silicone). It is a viscous liquid that cures (solidifies) quickly into a rubber-like solid, taking the shape of whatever surface it was lying against while curing.
