Abstract: A system may include a ventilation duct, which partially or completely surrounds a pluggable optoelectronic module. The pluggable optoelectronic module may be plugged into electronic equipment, which includes a fan to cause airflow from a front of the electronic equipment (where the pluggable optoelectronic module is plugged) to a rear of the electronic equipment. The ventilation duct may cause airflow to contact the pluggable optoelectronic module, such as at a heatsink of the pluggable optoelectronic module, as it goes from the ambient atmosphere to ventilation openings at the front of the electronic equipment.

Abstract: A system has a gas supply and at least one tank defining an interior. A first port is positioned within the interior of each tank of the at least one tank and is in selective fluid communication with the gas supply. A conduit extends between and provides fluid communication between the gas supply and the first port. A first valve is fluidly positioned between the gas supply and the first port. The first valve is configured to selectively permit fluid communication between the gas supply and the first port. A pressure sensor is in fluid communication with the conduit. The computing device is configured to: cause the first valve to open, receive a first signal from the pressure sensor indicative of pressure within the conduit, and determine a quantity of fluid in the tank based on the first signal from the pressure sensor.

Abstract: A composition for treating a disease affecting the hoof of an animal comprising an active ingredient and a colloid former is described. The active ingredient may comprise zinc sulphate, copper sulphate, an organic acid, an alkali metal salt or a mixture thereof. The composition as disclosed has the advantage that it is more effective at applying an active ingredient to a hoof than a conventional, non-colloid system.
