Polypropylene having high maleic anhydride content, between about 5 and about 45 g wt %, may be prepared by first reacting a metallocene-prepared polypropylene having terminal unsaturation with one mole equivalent of maleic anhydride to give polypropylene having a single unsaturation and a terminal succinic anhydride moiety. This product is then reacted with additional maleic anhydride in the presence of a free radical initiator (such as a peroxide or UV radiation) to give a polypropylene with maleic anhydride moieties along the backbone. The polypropylene product does not suffer scission or crosslinking with subsequently undesirable increases in molecular weight or viscosity. The maleic anhydride moieties provide reactivity to the polypropylene and thus expand its uses and applications.

A cache server prefetches one or more web pages from an origin server prior to those web pages being requested by a user. The cache server determines which web pages to prefetch based on a graph associated with a prefetch module associated with the cache server. The graph represents all or a portion of the web pages at the origin server using one or more nodes and one or more links connecting the nodes. Each link has an associated transaction weight and user weight. The transaction weight represents the importance of the link and associated web page to the origin server and may be used to control the prefetching of web pages by the cache server. The user weight may be used to change a priority associated with a request for a web page. The user weight and transaction weight may change based on criteria associated with the origin server.

A circularly shaped weight includes an opening in the center having a handle extending there through. The handle bi-sects the opening and creates equal openings for receiving a hand or foot of the user. The weight is particularly useful for individuals who may be incapacitated by arthritis or other physical ailments that may prevent them from properly grasping a weight. The novel shape is useful in stacking the weights when they are not in use. A plurality of circularly shaped weight may be fastened together via a coupler.

A method and system for selecting dental constructions using translucent materials that match an individual's preexisting tooth appearance uses a set of reference templates. The reference templates are constructed from layers of various translucent dental materials positioned on bases constructed from actual or simulated tooth structures. The layers of translucent materials have a thickness that varies in increments that correspond to the likely thicknesses of the materials when used in dental constructions. A reference table is created based upon color measurements of each of the reference templates. A color measurement of the individual's preexisting teeth is then compared to the reference table to determine which particular dental construction will most closely match the individuals preexisting teeth.

An elongated shaft has a shock-absorbing core, a fiber-reinforced durable plastic outer skin encasing the core, and an elongated stiffening member encased within the core. The elongated stiffening member may be a spar or a hollow tube. If it is a hollow tube, the tube may contain a weight that moves along the inside of the tube as the shaft is swung. The shaft also has a way to attach athletic equipment, such as a lacrosse head frame and net, to one end.

The invention relates to a permanent magnet direct current motor comprising: the inside of a shell of the motor is provided with a stator and a rotor, a stator core is provided with a winding coil, a rotor rotating shaft is provided with a magnetic core folded by discoid copper sheets. The periphery of the magnetic core is fixed with a rotor magnetic tile and the motor is provided with sensor magnetic steel and a position sensing element of a hall element. The sensor magnetic steel is arranged in a magnetic steel seat which is fixed on the motor rotating shaft extending out of an end cover and the sensor magnetic steel and the hall element are arranged in a cavity consisting of the end cover and a dust cover. As the magnetic steel seat is fixed on the motor rotating shaft extending out of the end cover, the permanent magnet DC motor is not interfered by the outside, so an electronic reversing signal of the motor is not interfered by the machining precision of the rotor and the armature current. The position sensing element is only influenced by the environment temperature, thereby leading the motor to work more stably.

A method may include receiving, by a CDN node, configuration information and conducting route exploration based on the configuration information to obtain an exploration value. After the CDN node receives an access request to a domain required dynamic acceleration, the exploration value of the CDN node and other CDN nodes may be multiplied by a corresponding weight associated with the configuration information, respectively, and corresponding values may be added together to obtain a path value of an individual return-to-source routing path. A return-to-source routing path may be further selected based on path values to perform a return-to-source operation. The techniques of the present disclosure achieve adjustment of selection orders of optimal return-to-source paths in various scenarios.
