摘要:
An ATV is described with a frame and at least three wheels suspended from the frame. At least one of the wheels is a front wheel and at least one of the wheels is a rear wheel. The front wheel defines a front axis and the rear wheel defines a rear axis. A power unit drives at least one of the wheels on the frame. A straddle-type seat is provided with a main seat portion for a driver and a secondary seat portion, rearward of the main portion, for a passenger. A back rest is also provided for the secondary seat portion, the back rest having a back-supporting front surface positioned in front of the rear axis. At least one of the wheels is steered by a steering member.

An all-terrain vehicle (ATV) includes a frame and a pair of front and rear wheels suspended from the frame. A straddle-type seat has a main portion and a secondary portion to accommodate a driver and a passenger. The wheelbase of the ATV is increased in length (compared to conventional ATVs) so as to increase stability and comfort for the driver, and/or to accommodate a passenger behind the driver. The passenger and secondary seat portion are disposed in front of the rear wheel axis and moved closer to the center of the wheelbase. Moreover, the combined center or gravity of the ATV, rider, and passenger is moved closer to the center of the wheelbase to improve stability, comfort and/or safety. The driver and passenger each have sufficient space to actively position themselves without significantly interfering with each other.

摘要:
The machinability characteristics of P/M ferrous sintered compacts are improved when the compact is prepared from a ferrous powder having a maximum particle size less than about 300 microns, and from at least about 0.01 weight percent of a boron nitride powder comprising agglomerates of irregular-shaped, submicron particles.

An alloy for after-fabrication hot-dip galvanizing containing mainly Zn to which is added Bi up to the solubility limit to improve drainage of the Zn alloy.
摘要:
The present invention is directed toward adjuvants that effect an innate and/or a specific immune response. The adjuvants contain at least one lipoprotein, such as Lip, Lip fragments or Lip variants, where the lipoprotein comprises at least one pentameric unit and at least one lipid moiety. Adjuvants wherein the lipoprotein make up at least 10% of the adjuvant by weight/volume are provided.
摘要:
The present invention relates to a method of obtaining different biologically pure cultures of bacteria isolated from different species of Taxus such as Taxus canadensis. T. brevifolia, T. baccata, T. cuspidata, and T. hunnewelliana, wherein the bacteria produce in vitro taxanes and paclitaxel, and wherein the bacteria are of the genus Sphingomonas, Bacillus, Pantoea or Curtobacterium. Also, the present invention relates to a method of a bacterial mass production of at least one taxane or paclitaxel. There is also disclosed a novel bacterial taxane. The present invention also relates to the use of different biologically pure cultures of bacteria isolated from different species of Taxus, wherein the bacteria are able to biotransform pro-taxanes. There is also provided a process for improving taxanes and paclitaxel production of taxanes and paclitaxel producing bacteria which include culturing bacteria in the presence of a mutagenic agent for a period a time sufficient to allow mutagenesis. There is disclosed two new mutated bacteria which have an increased yield of pro-taxane biotransformation.
