Abstract: Golf practice devices are adapted to facilitate practicing without obstructing a putting surface or practice area. According to one example, a golf practice device can include a first base member with a first clamping end and a first handle end, and a second base member with a second clamping end and a second handle end. A portion of the first base member located between the first clamping end and the first handle end may be hingedly coupled to a portion of the second base member located between the second clamping end and the second handle. At least one coupling arm may be pivotably mounted to the first base member, and an attachment feature may be coupled to the first coupling arm. In some examples, a sight or a cell phone with an integrated camera may be coupled to the attachment feature. Other aspects, embodiments, and features are also included.

Abstract: Golf practice devices are configured to facilitate putting without obstructing the greens. According to one example, a golf practice device can provide a visible indicator projected onto a surface of a golf green with a golf practice device coupled to a pole positioned vertically on the surface of a golf green. The golf practice device includes a base, a sight and a turret. The turret rotationally couples the sight to the base providing for rotationally positioning the sight to selectively place the visible indictor on the surface of the golf green, thereby providing a determined putting distance between the visible indicator and the pole. Other aspects, embodiments, and features are also included.

Abstract: The present invention relates to a live vaccine against Pasteurella multocida, for application of poultry by injection, per os or as aerosol, containing an attenuated non-virulent genetically stable strain of Pasteurella multocida, to a process for producing an attenuated genetically stable non-virulent strain of Pasteurella multocida, which comprises cultivating a virulent field strain, selecting after 18 hours at 37.degree. C. colonies of uniform size, of about 4 to 5 mm diameter, suspending these in a pH 5.5 buffer, subjecting same to a mutagen at a concentration causing a mortality of 90-99% after 30 minutes at 37.degree. C., centrifuging the microorganisms, washing same, plating same and selecting colonies of not more than 2.5 to 3 mm diameter after 18 hours at 37.degree. C.
