摘要:
A mild inexpensive process for treating lignocellulosic biomass involves oxidative delignification of wood using an aqueous solution prepared by dissolving a catalytic amount of manganese (III) acetate into water and adding hydrogen peroxide. Within 4 days and without agitation, the solution was used to convert poplar wood sections into a fine powder-like delignified, cellulose rich materials that included individual wood cells.
摘要:
In one implementation, an object analysis system identifies an object within a software module, and determines a size of the object based on at least one operation within the software module. The object analysis system identifies the object and determines the size of the object without reference to source code of the software module.

This disclosure is directed to a device for facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The device includes an intravascular device including a shaft having a distal end and a proximal end. The device includes a handle assembly fixed about the proximal end of the shaft, the handle assembly including a first portion. Rotation of the first portion in a first direction about a longitudinal axis of the shaft causes rotation of the shaft in the first direction when a torque applied by the first portion to the shaft is below a first maximum torque. Further rotation of the first portion in the first direction about a longitudinal axis of the shaft does not cause rotation of the shaft in the first direction when the torque applied by the first portion to the shaft is equal to or above the first maximum torque.

Mechanically attached connections for conduits may include a conduit gripping member and first and second connection members. The first and second connection members may be, for example, a nut member and a body member where the connection members cause axial movement of the conduit gripping member to grip and seal the conduit when the assembly is pulled-up. The mechanically attached connection may include a sensing function for detecting or sensing a condition or characteristic of at least one of the following: the mechanically attached connection, one or more of the connection members, the fluid contained by the mechanically attached connection, or a combination thereof. The sensing function may be, for example, a sensor that is integrated with at least one of the nut member and the body member.

System, method and program product for detecting a malicious SQL query in a parameter value field of a request. The parameter value field is searched for query operands, characters and/or symbols and combinations of query operands, characters and/or symbols indicative of malicious SQL injection. A respective score assigned to each of the query operands, characters and/or symbols or combinations of query operands, characters and/or symbols found in the parameter value field is added to yield a total score for at least two of the query operands, characters and/or symbols or combinations of query operands, characters and/or symbols found in the parameter value field. Responsive to the total score exceeding a threshold, the request is blocked.

Devices, systems and methods for treating diseases and disorders effecting the cardiovascular system of the human body are disclosed. An exemplary blood vessel in accordance with this disclosure comprises a shaft, tip member fixed to the shaft, and a probe extending beyond a distal surface of the tip member. In some useful embodiments, the tip member is relatively atraumatic and the probe is shaped so as to be more likely to produce trauma than the tip member.
摘要:
A method and system for ordering and aggregating log streams. Log streams for events from different sources are received. If different sources have different recording cycles, or time epochs, that lead to different temporal granularities, then all of the log streams are combined into a single time epoch that is equal to the longest time epoch. Log streams from sources having shorter time epochs continue to retain information about their original time epochs, in order to retain information about the order of the events in those log streams. The log streams are re-ordered, both before and after being integrated into the aggregate log, by acquiring additional data from the different sources, thus permitting the likely cause/effect relationship between events.
摘要:
A light source includes a base, a light-transmissive envelope coupled to the base, a composition disposed within the light-transmissive envelope, and a gas phase contained by the envelope for suppressing vaporization of the composition at operating temperatures greater than about 2000 Kelvin. The composition includes a first region and a second region and operable to suppress or reflect photons having a wavelength greater than about 700 nm and to emit or transmit photons having a wavelength between about 400 nm and about 700 nm.
