Abstract: A method for mitigating airborne pathogens from a livestock house is disclosed. In an embodiment, the method comprises using a cross-flow ventilation system, which is fluidly connected to a livestock house and configured to control the air quality and movement by introducing ambient air into at least one air filtration system that is attached to a side wall of the house; conditioning the air in the air filtration system by performing at least one step selected from filtering, cooling, disinfecting, or pressurizing the air; introducing the conditioned air into an air chamber; flowing the conditioned air from the air chamber into the house through at least one ventilation panel to the opposing sidewall with a laminar or substantially laminal flow of air; and removing the air from the house using an exhaust fan attached to a side wall opposite the side wall containing the air filtration system.

Abstract: A process for the production of a fluorobenzonitrile wherein a chlorobenzonitrile having a chlorine atom in an ortho- or para- position with respect to a nitrile group is heated with an alkali metal fluoride at a temperature between 200.degree. and 250.degree. C., in the presence of sulpholane.

Abstract: A method of preparing a fluoronitrobenzene containing a fluorine atom in the para position with respect to the nitro group, comprising heating a polychloronitrobenzene or chloronitrobenzene containing a chlorine atom in the para position with respect to the nitro group with an alkali metal fluoride in the presence of sulpholane.
