| タイヤの接地面に作用する応力を測定するために, タイヤラグフェースの一点における法線方向応力, 接線方向応力及び横方向応力を同時に測定できる測定器を開発した。本測定器を1本のタイヤラグの3ヶ所すなわちタイヤ踏面中心部, 同側端部ならびにこれらの中間部の3ヶ所に埋め込んで各応力を測定した。測定例としてすべり率20%時の応力分布状態を示し, 最大接地応力値及び発生位置を検討した。 A three-dimensional stress transducer was developed to measure normal，tangential and lateral stresses on the lug face between a tire-lug and soil. Three transducers were mounted on the part of lug - end which is almost the same place of the tire tread center，on the outer edge of lug and a intermediate place of above two places. The stress distributions of three transducers were presented and the relationships between peak stresses and their rotational angles at 20% slippage were discussed. |

| The Betsukai town office implemented bovine viral diarrhea virus (BVDV) preventive activities (i.e., vaccination and surveillance) in 2006. Using bulk tank milk screening followed by individual blood tests using a Reverse Transcription-Polymerase Chain Reaction (RT-PCR) method, persistent infection (PI) cattle were detected and eliminated from the population. Based on data for PI cattle detected between 2006 and 2007, we conducted a case control study to find risk factors associated with the presence of PI cattle. Significantly associated farm level factors for increasing risk of producing PI cattle include; 1) no recent purchase of cattle (between 2004 and 2007) and 2) no prevention of people/animals entering the premises. This study suggests that not... |
