摘要:
Rapid, voltage controlled phase modulation of continuous wave THz radiation is demonstrated. By transmitting an infrared laser beam through a phase modulator, the phase of the THz radiation which is generated by the photomixing of two infrared beams can be directly modulated through a 2π phase shift. The 100 kHz modulation rate that is demonstrated is approximately three orders of magnitude faster than what can be achieved by mechanical scanning.

摘要:
Non-invasive THz spectroscopic apparatus and methods are provided for detecting and/or identifying constituents such as variations in a structural entity where chemical or biological entities can reside. Position dependent scattering of THz radiation is employed to image voids and defects in the internal structure of samples, enabling the determination of contamination, spoilage or readiness of products such as wine in sealed containers.

Aspirin is one of the most widely used drugs in the treatment of inflammation, pain and fever. It has more recently found application in the prevention of heart attacks and stroke and is being studied as a cancer chemopreventative agent. Despite its value aspirin continues to be underutilized because it causes gastric bleeding. The technology under development potentially removes this problem. It is designed to reduce contact between the drug and the intestinal lining. An isosorbide aspirinate prodrug compound is thus provided. The compound has the general structure as shown in general formula (I) wherein Y is a C1-C8 alkyl ester, a C1-C8 alkoxy ester, a C3-C10 cycloalkyl ester, an arylester, a C1-C8 alkylaryl ester or —C(O)ORring, wherein Rring is a 5-membered aromatic or nonaromatic 5-member ring having at least one heteroatom substituted for a carbon of the ring system, which can be unsubstituted or substituted with at least one nitric oxide releasing group.

According to some embodiments, a plurality of new work notifications are received, each associated with a producer identifier. A set of non-appointed new work notifications may be determined, including a first non-appointed new work notification and a second non-appointed new work notification, the second non-appointed new work notification being received after the first non-appointed new work notification, and at least some of the non-appointed new work notifications may be automatically prioritized such that the second new work notification is assigned a higher priority as compared to the first new work notification. It may then be arranged for a manual appointment processing procedure to be performed for at least some of the non-appointed new work notifications in accordance with the prioritizing.
摘要:
A needle assembly (N) for RF ablation of target tissue in e.g. the liver (L) of a patient comprises a radial array of electrodes (1) in the form of loops which can be expanded by feeding the proximal ends of the Y electrodes along the bore of the needle assembly. An RF power supply (2) is connection between the array of electrodes and a skin pad (P) in contact with the skin (S) of a patient and, in accordance with the invention, is biased by a DC power supply 4 which generates electro-osmotic and/or electrolytic effects in the target tissue. In particular, chloride ions are discharged to generate chlorine which has a potent cytocidal effect and water can be attracted to the array of electrodes by electro-osmosis, thereby alleviating the problems of low electrical and thermal conductivity encountered with conventional apparatus.

摘要:
A falling film evaporator is provided for use in a two-phase refrigeration system or process system. The evaporator includes a shell having an upper portion, a lower portion, and a tube bundle having tubes extending substantially horizontally in the shell. A hood is disposed over the tube bundle, the hood having an upper end adjacent the upper portion above the tube bundle, the upper end having opposed substantially parallel walls extending toward the lower portion, the walls terminating at an open end opposite the upper end. Once liquid refrigerant or liquid refrigerant and vapor refrigerant is deposited onto the tube bundle, the substantially parallel walls of the hood substantially prevent cross flow of refrigerant vapor or liquid and vapor between the tubes of the tube bundle.
摘要:
A heat exchanger is provided having a first path and a second path through which air passes with heat transferred between the two paths. Exterior moist air is delivered to the first path together with a dissolved desiccant. An exothermic reaction takes place with heat transferred to the second path. Moist air passes through the second path with water in the second path being caused to evaporate thereby cooling air passing along the second path.

A rotor blade sensor for detecting a rotor blade (430) comprising an electrical oscillator arranged to generate an oscillating signal. An antenna (300) includes a coil (100) having one or two winding layers coupled to the electrical oscillator. The antenna (300) may instead or as well include a coil (100) comprising a plurality of winding layers, each layer being separated by al spacer for substantially reducing inter-layer capacitance, being coupled to the electrical oscillator. The antenna (300) is driven in use by the oscillating signal of the oscillator at substantially a resonant frequency of the antenna (300). The antenna generates an antenna electromagnetic field that interacts with a rotor blade (430) such that the electrical characteristics of the antenna (300) vary as the interaction between the antenna (300) and the rotor blade changes and a detector circuit is arranged to monitor these electrical characteristics.
